6. Working Principle of the 3D Printer
For 3D print, first a file is needed that contains the three-dimensional data of the object to be printed (a common format of such a
file is, e.g., a .stl-file).
This file can be produced with the corresponding software or with a 3D-scanner. There are also many printing files already online
that can be downloaded to print an object as quickly as possible.
The actual printer software has the task to render the above three-dimensional file into a file that the printer can print. This is a
file in which the individual print layers, the print temperatures for printing head and heating bed, etc. are specified. The file has
the extension “.gcode”.
This GCODE printing file is sent to the 3D printer either via the USB interface by the computer, or an SD card with the printing file
is put into the card reader and the 3D printer is used in standalone operation.
The 3D printer then prints the print file layer for layer according to the FFF (Fused Filament Fabrication) / FDM (Fused Deposition
Modelling) procedure.
At the actual print, the filament material is transported from the filament roll to the print head (extruder).
In the extruder, the filament material is melted and then applied to the heating plate via a fine extruder nozzle layer by layer.
The heating plate moves in the Y and Z directions, the extruder moves in the X-direction. Thus, all prerequisites to produce a three-
dimensional object by horizontal application of the present layers are created.
A 3D printer is a highly complex device in which many parameters must be set depending on the printer, printed object
and filament material used.
Additionally, the adhesion of the printed object on the printing plate is influenced by printing plate temperature, fila
-
ment material, shape of the printed object and surface properties of the printing plate.
Ambience influences such as drafts, grease on the printing plate, etc. also play a role in the quality and adhesion of the
printed object.
For the above reasons, it is not possible to achieve high-quality print results at once and without previous experi
-
ments.
Change the adjustable parameters in small steps to achieve the best printing results for your application. The printing
examples enclosed on the SD-card provide references, but must be refined for perfect results depending on the above
parameters.

9. Assembly of the Mechanical Parts
The following chapters refer to the assembly of the 3D printing construction kit, but are also interesting for owners of the ready-
made device as information for later accessory assembly.
If you have purchased the finished device, you can skip the following chapters and continue directly with the chapter “Initial
commissioning”.
a) General Information
Take enough time for the assembly. Hurrying often leads to mistakes that may damage components or ruin the time
benefit by elaborate rework.
The workplace should be suciently large and clean so that the dierent components and assemblies can be put down
and installed easily.
The
stainless steel parts of the construction kit are very sensitive to dirt. Wash your hands before installing these parts
and use cotton gloves if necessary. Remove the protective film only directly before assembly.
Always observe the images during assembly. Here, the assembly locations and correct alignment of the components
are shown.
All mechanical components of the construction kit are produced extremely precisely. Never apply any force during as
-
sembly. All parts can be assembled without any great application of force. If this is not the case, rethink the assembly
step and reread the corresponding description in these instructions.
When tightening the screws, ensure that you do not tighten them too tightly. Many screws are turned into aluminium
threads and therefore must not be tightened as far as it would be possible, e.g., in steel threads. A table with the re-
commended tightening torques of the screws can be found in the appendix of these instructions.
Sort the screws by size before assembly. This facilitates assembly, since you do not have to look for individual screws.
For
countersunk-head screws, the length (l) is measured with the screw head; for cylinder head screws, the length
measurement takes place without the screw head. The diameter (d) is always measured by the thread.
9
Application of the threadlocker varnish
In the following instruction, some screws must be secured with threadlocker varnish. This is indicated accordingly in the text.

10. Wiring of the Electrical Components
a) General Information
ATTENTION Mains voltage - the connection, installation and wiring of the electrical components must only be perfor-
med by an electrician who is familiar with the applicable safety provisions. Before commissioning, inspection accor-
ding to the applicable safety provisions must be performed by an electrician.
During the connection work, the mains line must never be connected to the mains.
Drag
chains
The drag chains have tabs on one side of the links through which the lines are pushed into the chains. Since the drag
chains can only be bent in one direction, the tab position must be observed (open on the inside > bottom in the follow-
ing figure and open on the outside > top in the following figure). This is indicated when describing the individual work
steps.
When pushing in the lines, always push in the stronger lines first and then the thinner ones. If the tabs of the drag chains
do not return to their initial position when pushed in, the tabs can be pulled back carefully with long-nosed pliers.
The
lines must be cleanly placed next to each other in the drag chain and must not be twisted.
When clipping in the drag chain ends into already-installed drag chain end pieces, small flat pliers with which the end
links of the drag chains are latched in the nipples or holes of the end pieces are helpful. Observe that the drag chain ends
latch cleanly with the end pieces. Do not apply any great force, since the plastic material would be damaged otherwise
and the drag chain or end piece would be rendered useless (loss of warranty/guarantee!).
Lines
Lines that may be swapped are marked with numbers.
These
numbers are placed on labels and line ends that are connected to the PCBs in the device socket. Therefore, ob
-
serve that the marked line ends must be placed in the device socket when placing the lines.
In the Annex, you will find a wiring plan for the main PCB in which the required line connections are marked.

11. Final Work
If the motors are moved manually, the display may light up. This is not a malfunction. A voltage induced by the movement
causes the display to light up.
Connection of the earthing plate
Place the heating plate onto the spacer bolts of the undertable
and connect the two plug connectors from line 12 and 20.
Basic
setting limit switch Z-direction
Loosen
the actuation screw in the Y-plate for the limit switch in
the Z-direction and turn it all the way into the hexagon bolt.
Carefully turn the toothed belt of the bottom plate until there is
a gap of 0.5 mm (+/-0.2 mm) set between the heating plate and
extruder. 0.5 mm correspond roughly to the thickness of 5 lay
-
ers of printer paper (80 g/m²).
Caution:
No force must be applied to the heating plates, since
the ceramics material would break otherwise (loss of war
-
ranty/guarantee).
Set the adjustment screw so that the limit switch of the Z-di
-
rection is tripped in this position (a slight click is audible).
Move
the extruder and Y-plate manually and ensure that the
extruder cannot touch the heating plate anywhere in the work
-
ing area and that the same distance is complied with every-
where.
If this is not the case, the undertable plate must be aligned
carefully. However, the heating plate must be taken o first
(danger of breaking!).
After this setting, counter the setting screw with the nut
again.
55
Discharge tensions of the threaded circulation spindles
Slightly loosen the attachment screws of the threaded circula

12. Initial Commissioning
Before initial commissioning, all transport protections or fuses that have been installed during installation must be
removed.
a) Assembly of the Filament Holder and the Filament Hose
Assembly of the filament holder
1x hexagon screw M8x120
2x
car body washer M8
4x nut M8
Push the hexagon screw from the inside outwards through the
corresponding bore in the left side part and attach it from the
outside with a nut.
Put on car body washer and counter with another nut.
At
the end of the hexagon screw, turn on a nut, enclose the car
body washer and counter with another nut.
Note: Printable adapters for dierent filament rollers can be
downloaded from the product page of the 3D printer online.
Push filament hose into the feed basic part and fasten it at the
filament hose holder with a small cable tie (99 mm).
Caution:
do not contract the table tie too far. The filament hose
must not be crushed.
Align the filament hose so that it has enough play for move
-
ments of the extruder carriage.
Note:
Filaments from various manufacturers cause a high friction
resistance in the hose. Therefore, please check that the fila
-
ment can be moved freely before use. If friction is too high,
the alternative filament holder (see „First Print of an Example
Object from the SD Card“) can be used.
58
b) Insertion of the Filament
Pull the filament hose end from the infeed basic part.
Push the filament roller onto the filament holder and guide the
filament through the filament hose until it escapes on the other
side.
The filament roller must move freely.
Cut into the filament end at a 45°-angle. Insert the filament
through the bore and past the feed motor into the extruder to
the stop.
Push
the filament hose end into the infeed basic part.
Tighten all spring screws so that the filament is cleanly guided
but also is not deformed badly by the filament feed.
It must be possible for the feed motor to turn without slippage
or catching when pulling or pushing at the filament.
The filament must be guided in a straight line from the top be-
tween the feed motor and the ball bearing into the bore at the
extruder. It must not catch at the bore edge of the extruder.
59
c) Setup and Transport
When setting up the 3D printer, observe that the mains switch at the low power device combination socket must be
easy to reach so that the device can be switched o quickly and easily in case of malfunction.
Ensure proper ventilation when setting up the device. Do not put the device down on soft supports such as a carpet or
bed, etc. the air circulation also must not be impaired by other objects. This prevents heat dissipation from the product
and may lead to overheating (danger of fire).
When setting up the device, make sure that it has a stable footing and place it on a stable underground. Persons may
be injured if the 3D printer drops.
When setting up the device, make sure that the connection cables are neither pinched nor damaged by sharp edges.
Always place cables so that no one can trip over them or be caught in them. There is a danger of injury.
Never place the device on any valuable or sensitive furniture surfaces without sucient protection.
Put up the 3D printer on a level, stable and non-vibration-sensitive surface.
If you want to transport the 3D printer, secure the moving parts and the heating bed with adhesive tape or cable ties.
d) Mains Connection and First Activation
The mains socket to which the 3D printer is connected must be close to the device and easily accessible to quickly
separate the device from the mains voltage in case of an error.
Do not let the mains cable come into contact with other cables.
Be careful when handling mains cables and mains connections. Mains voltage may cause potentially fatal electric
shock.
Make sure that no cables lie around openly. Install cables professionally to prevent accidents.
Before plugging in the mains plug, ensure that the device voltage indicated at the 3D printer corresponds to the availa
-
ble mains voltage. Do not connect the device if the indication does not correspond to the available mains voltage.
Incorrect supply voltage may lead to irreparable damage to the device and danger to the user.
Plug the low power device plug of the mains line into the low power device combination socket at the rear of the device.
Plug the mains plug of the mains line into a protective contact socket.
Switch on the printer with the mains switch at the low power device combination socket (put the switch in position I).
The
lighting now lights up and the display shows the welcome screen briefly.
Then the main menu appears:
(1) Extruder
temperature (actual/target)
(2) Temperature heating bed (actual/target)
(3) Print
plate oset in mm from the home position
(4) Measured value of the print sensors at the extruder
(5) Status information
The target temperatures are not displayed here yet, since the extruder and heating bed are not heated yet.
60
Function description of the operating buttons:
(1) Direction buttons for navigation in the menu structure (left / right / top / bottom)
(2) OK
button for confirmation of a selection in the menu
(3) Heating plate movement up / down
(4) Filament infeed + = forward / - = back
(5) Printing pause
1x push: Print stops
2x
pushes: Printing head moves away from printed object (the previous position remains saved)
(6) Continuation
of print after a printing pause
e) Calibration
Before calibration, filament must be inserted (see “Insertion of the Filament”), since the measured values are falsified
otherwise. The filament must not be introduced into the extruder in this case, however. It only needs to be clamped
between the ball bearing and infeed knurl. If there is already some filament in the extruder, move it out with the manual
filament infeed first. Caution: If the extruder has already been used, it must be heated first.
Calibration should be performed now and then. It is a prerequisite for high printing quality. Perform the calibration after
a transport of the 3D printer or any changes to the heating plate in any case.
This calibration does not replace the correct basic setting of the limit switch for the Z-direction. It serves to balance
out slight irregularities of the heating plate while printing.
Ensure that the heating plate is supported levelly on the spacer bolts.
Ensure
that the extruder nozzle is clean on the outside. If it is contaminated, clean it as described in chapter “Mainte
-
nance and Care”.
The figures on the display screens may vary a little depending on firmware version.

Push OK Select „Extruder“ with the direction buttons.
Push OK and select „Bed Temp“ with the direction buttons. Push OK
Set „100 °C“ with the direction buttons. Push OK
Push the direction button „left“ 2x to return to the main menu.
Wait until the actual temperature of the heating plate in the
display indicates 100 °C and then let heating continue for ap
-
prox. 5 more minutes until the temperature of the heating plate
has stabilised.
Push OK and select „Configuration“ with the direction but

tons.
Push OK and select „Heat Bed Scan“ with the direction but-
tons.
62
Push the direction button „left“ 2x to return to the main menu.
The status display of the main menu shows „Heat Bed Scan“.
The geometry of the heating plate is now measured automati
-
cally. This process will take a while.
After
measurement, the heating plate returns to the home posi
-
tion and the display shows „Scan completed“.
If
the display shows „Scan aborted“, this means that
measurement has been aborted. In this case, repeat
the basic setting of the limit switch for the Z-direction
(see chapter „Final Work“ earlier in these instructions).
Push OK Select „Extruder“ with the direction buttons.
Push OK and select „Bed Temp“ with the direction buttons. Push OK
Set
„0 °C“ with the direction buttons. Push OK
63
Push the direction button „left“ 2x to return to the main menu.
Wait until the actual temperature of the heating plate in the
display shows room temperature again.
f) First Print of an Example Object from the SD Card
When heating, there may be slight development of smoke or steam. This is normal. Please ensure the corresponding
ventilation.
If you are printing with PLA filament, cover the heating plate with cleaning tape or a slightly structured crepe tape.
You can find the print files on the enclosed SD card in the folder GCODE. The printing files are saved in the two folders
“ABS” and “PLA” depending on the filament type used.
Push the enclosed SD card into the SD card reader at the right of the 3D printer.
Push OK and select „SD-Card“ with the direction buttons. If
the printer was already switched on before insertion of the SD
card, the option „Mount Card“ must be performed.
Push OK and select „Print file“ with the direction buttons.
Push
OK and mark the desired file in the corresponding folder
„ABS“ or „PLA“ with the direction buttons.
Confirm with OK.
The display returns to the main menu and the heating plate is
heated.
Then the axes move to the home position and the extruder is
heated.
Once the extruder has reached its operating temperature,
printing starts.
The progress of heating of the heating plate and extruder can be tracked based on the temperature displays in the upper
display line.
The printing progress can be tracked in the lower status display.
64
During the first centimetres of printing, the distance between the heating plate and extruder can be fine-adjusted manually with
the buttons for heating plate movement (3).
It should be approx. 0.2 mm (corresponds to about twice the paper thickness of regular 80g/m² printer paper).
For this setting, observe that the extruder must not touch the heating plate since it may be damaged otherwise (loss of
warranty/guarantee).
The distance between the extruder and heating plate is set precisely with the software later (Z-compensation), but the
manual setting is sucient for the first prints.
If no filament escapes from the extruder at first, the filament infeed button (4) must be pushed until filament escapes.
Let the printed object cool o for a few minutes after printing. When the temperature of the heating plate is below 40 °C (see dis
-
play), the printed object comes free from the heating plate and you can remove it.
Removing
the SD card
Push OK and select „SD-Card“ with the direction buttons. Push OK and select „Unmount Card“ with the direction but
-
tons.
Push OK again and then remove the SD card.
Push
the direction button „left“ 2x to return to the main menu.
The enclosed SD card holds, among others, a printing file for an alternative filament holder (file name
“Filament_guide.gcode”, also see description enclosed with these instructions).
You can install this filament holder instead of the filament hose at the 3D-printer. For this, cut a short piece (approx. 3 cm)
from the filament hose and plug it into the filament introduction at the extruder as a centring piece.
65
13. Operation at the Printer
a) Menu Overview
Operation takes place via the left key block at the printer:
The direction buttons are used for navigation in the menu structure (left / right / top / bottom)
The OK button is used to confirm a selection in the menu and to call the menu structure from the main menu (description above
under “Mains Connection and First Activation“).
The menu structure may deviate slightly depending on firmware.

14. General Notes on 3D Printing
The print quality of 3D printers depends on a great many factors.
It is not always possible to achieve a satisfactory print result at the first attempt.
Extruder
temperature
The best extruder temperature depends on the filament material and the printer layer thickness. The manufacturer information for
the printing temperature can vary very strongly here.
Perform the first test prints at a temperature in the middle range of the manufacturer’s information.
To optimise the print quality, print the same object with the same printing layer thickness and dierent extruder temperatures in
5 °C steps and then compare the results.
This way you can approach the best extruder temperature for dierent filaments and printing layer thicknesses most easily.
If
the extruder temperature is set too hot, the material cannot cool o fast enough and will melt the layer below again.
If the extruder temperature is too low, the filament will not become liquid enough and the filament flow is not homogeneous. The
individual filament layers also cannot combine suciently.
Heating
bed temperature
The best heating bed temperature also depends on the filament material. It permits perfect adhesion of the printed object to the
heating plate.
PLA can also be printed without a heating bed, but a temperature of approx. 60 °C has turned out to be ideal.
When printing PLA (particularly at small objects with a small footprint), the heating bed should additionally be applied with clea
-
ning tape or a slightly structured crepe tape to increase surface adhesion.
ABS needs a heating bed for printing. Otherwise it will not adhere at all or only insuciently. Here, a temperature of approx.
160 °C should be tried out.
If the heating bed temperature is too high, the printed object may distort or the lower layers will cool o too slowly.
If
the heating bed temperature is too low, the printed object will not adhere suciently or the corners will come free of the heating
plate while printing.
Print layer thickness
The
print layer thickness determines the height of the individual print layers and thus the resolution and quality of the printed
objet.
The thinner the printed layers, the better the print quality and the longer the print duration.
The thinner the printed layers, the lower the print quality and the shorter the print duration.
Experiment with the above parameters to find the best printer results for you depending on the material used.
The
first print attempts should be done with PLA filament, since it is a material that can be mastered relatively easily and
that is subject to fewer problems with shrinkage, accuracy and adhesion on the heating plate.

15. Software “Repetier Host”
a) General Notes on Software
It is unfortunately not possible to explain the complete function of the enclosed software in the scope of this instruction. For this,
we refer to the integrated online help function and the information on www.repetier.com.
The basic operation and the path to the first printout are, however, described below to that you can get a result quickly and
easily.
The enclosed SD card holds a custom version of the software that contains the printer settings and configuration files
for the RF1000 in the folder “Repetier-Host”. We urgently recommend to install the custom version of the software since
then you do not need to configure the software and the required drives are already installed as well.
Configuration of the software and driver installation are explained below in the Annex to these instructions for the
sake of completeness. However, the software only needs to be configured if you install the basic version of the soft
-
ware from www.repetier.com. The configuration files required for this are enclosed on the included SD card in the
folder “Slic3r Settings”.
If you have already installed a previous basic version of the software, the old version can be uninstalled and the cu
-
stom version can be newly installed. The slicer settings of the previous version are not deleted and reappear in the
custom version.
The software Repetier-Host performs the following tasks:
Placement of the 3D-object to be printed on the printing plate.
Slicing of the object to be printed into thin layers that the 3D printer can print out layer for layer. The result of this process is a
G-Code file.
Review
of the G-Code files for error and printability.
Sending the G-Code files to the printer or saving on an SD card for standalone print.
Monitoring the 3D printer in operation.
Setting and storage of printer and filament-specific data.
b) Installation
Install the file “setupRepetierHost_RF1000_3D_x_xx.exe” from the directory “Repetier-Host” from the SD-card (x_xx designates
the software version here).
For the installation of the custom version of the software the user has to be registered as an administrator. Otherwise the
necessary configuration files and printer settings won´t be installed.
Alternatively, the installation file for the basic version of the software can also be downloaded from www.repetier.com. There,
MacOS X- and LINUX versions of this software are oered as well.
Prerequisites for installing under Windows:
Microsoft
.Net Framework 4 must be installed on the computer. This software can be downloaded free of charge from
www.microsoft.com.
The further system requirements for installation of Repetier-Host (also for other operating systems) are found on www.
repetier.com.
Updates for Repetier-Host are regularly published under www.repetier.com. Updates of the custom version can be found
on www.conrad.com in the download area on the product page of the 3D-printer.
71
c) Connection of the Connected Printer
Start the programme Repetier-Host and select printer settings at the upper right in the window.
(1) Set the port and baud rate as displayed.
The port number is system-dependent. You can find it in the device manager of the control panel, under connections
(COM and LPT).
(2) Click “OK”.
72
Click “Connect” in the upper left of the main screen of the software.
After a few seconds, the symbol appears in green and the label turns to “Disconnect”.
The printer has successfully been connected to the software and only some manual settings can be tested.
73
d) Manual Operation via the Software
Click the tab “Manual Control” on the main screen of the software.
Before trying out manual printer control, the settings for the limit switches for the Z and Y axes must have been per-
formed (see pages 31 and 54). In the finished device, this has already been performed at production but should be
inspected again for reasons of safety.
If this is not observed, there may be damage to the 3D printer (loss of warranty/guarantee).
(1) Printer
moves into the home position
(2) X-axis
moves into the home position
(3) Y-axis moves into the home position
(4) Z-axis moves into the home position
(5) The arrow icons can be used to operate the corresponding axes manually. Depending on where the arrow is clicked,
dierently long routes are run. The route length is displayed when the mouse pointer is moved across the corresponding
button of the arrow.
(6) Switch o motors to move them manually.
(7) Printer
moves into the parking position.
(8) Switching the extruder heating on/o, e.g. to heat the extruder before filament change. Below this, the temperature and
filament infeed can be operated.
(9) Switching the heating bed on/o. Below this, the temperature can be set.
74
e) Placement of a Printing Object in the Software
Click the “+” symbol on the main screen of the software in the object placement tab.
Select the desired file and click “OK”.
The 3D object “drops” onto the printing plate in the main window.
The following file types can be opened with this software:
*.stl
(STL-files)
*.obj (OBJ-files)
*.3ds (3D-Studio-files)
In the folder «STL» on the enclosed SD card, you will find a few examples for the first printing attempts. However, there
are already many places online where you can download 3D files (e.g. www.thingiverse.com).
Alternatively,
you can, of course, also use a 3D programme to make your own.
75
Short description of the most important buttons in the object placement tab:
(1) Adding objects (as described above)
(2) Deleting the objects from the printing plate
(3) Copying
objects for multiple printing (in another window, the number of copies can be chosen)
(4) Centring the object on the printing plate
(5) “Dropping” again (this button should be pushed again before the further steps to ensure that the object is supported cleanly
on the printing plate)
(6) In the fields below, the object can still be moved, scaled and rotated.
Use the scaling function to compensate the size retention of the printed object here as well. If it is known, e.g., that the
filament material used shrinks by 2 %, set the scaling to the value 1.02 (this is an approximate reference value). After
printout, you can measure the object and adjust scaling again if required.
76
f) Preparation for Print
To be able to print the object, it first needs to be sliced into individual printing layers. This process is referred to as “slicing”.
Slicing of the placed printing object
(1) Select
suitable slicer settings for your print.
The settings are always marked with the following routine:
Printer_Filament material_Layer thickness_Nozzle diameter
Example: RF1000_ABS300_100_05 = RF1000_3mm ABS_layer thickness 100 µm (= 0.1 mm)_nozzle diameter 0.5 mm
Always use the same settings in the input fields “Print settings”, “Printer settings” and “Filament settings”.
(2) Further settings can be made optionally here. However, this should only be done by experienced users. For functions, see
the
online help function of the software.
(3) Click “Slice with Slic3r”, to slice the 3D file.
77
The finished printing file appears in the graphics window after calculation.
To the right of it, the G-code (layer description) appears, and below a control with which the layer view can be influenced.
This layer view serves to check for errors before printing.
In
the very left of the screen, there is a tool bar that serves view control.
For more detailed descriptions of the functions, see the online help function of the software.
78
g) Printing
The printing file produced in this manner can be printed now. There are two options for this:
(1) Click “Save Job” to save the print file on an SD card and then print it out stand-alone.
(2) You
can also click “Start job” to send the file directly to the connected 3D printer via the USB interface of the computer and
print it.
Here, the log window (3) below the image shows current information on software, slicer and printer during printing.
79
The graphics window may be switched to display temperature curves. There, the temperatures and their course are graphically
displayed in a chart.
During
the first centimetres of printing, the distance between the heating plate and extruder can be manually adjusted with the
buttons for heating plate movement (3).
It should be approx. 0.2 mm (corresponds to about twice the paper thickness of regular 80g/m² printer paper).
For this setting, observe that the extruder must not touch the heating plate since it may be damaged otherwise.
The distance between the extruder and heating plate is later set precisely with the software but the manual setting is
sucient for the first print.
If no filament escapes from the extruder at first, the filament infeed button (4) must be pushed until filament escapes.
At PLA printing of small objects with a small footprint, it is recommended to apply the heating plate with cleaning tape or
a slightly structured crepe tape before printing. Spraying the heating plate with hair spray can be helpful here as well.
These measures increase adhesion of the printed object on the heating plate.
Let the printed object cool o for a few minutes after printing. When the temperature of the heating plate is below 40 °C (see dis
-
play), the printed object comes free from the heating plate and you can remove it.
If the printed object does not come loose easily, you can loosen it carefully with a painter’s spatula, knife, etc.
Do not apply any mechanical force on the heating plate. Danger of heating plate breakage!
80
h) More Detailed Description of the Slicer Functions
Below some settings of the slicer are explained that are only to be changed by experienced users. The use of wrong
settings can result in damage to the 3D printer or defective printouts.
Beginners should first work with the basic settings that are integrated in the custom version in any case.
If you make any changes to the settings, these must be saved in the configuration settings by clicking the disc icon.
Save the dierent settings as a configuration setting. Assign unique names for the dierent configuration settings so that
you can assign them uniquely to the dierent filament types, print resolutions, etc. later.
For
more information, read the integrated online help function.
Click the software in the tab “Slicer” (1) to Configure (2) in the right window.
The window of the slicer (3) is opened.
81
Print Settings
(1) Layer height (accuracy/resolution of the print object)
(2) Layer
height of the first layer (influences the adjustment and adhesion on the printing plate; set the first layer a little thicker
than the following layers)
(3) Number of outer wall layers
(4) Activate for hollow bodies (e.g. vases)
(5) Filled layer number top/bottom
(1) Object
filling (0-1 = 0-100%)
(2) Filling
pattern of the object and the first and last layer
82
(1) Loops are circles, that are drawn around the object when printing starts, stabilise the filament flow before the actual object
is printed. Here, number, distance from the object, height and minimum length are specified.
(2) Brim is a thin edge that is placed right around the object to increase the footprint and thus adhesion to the printing plate.
Here,
the width of the brim is specified.
(1) Selection and adjustment of the supporting material that is needed when printing complex objects such as bridges or hollow
spaces (poss. required for printing object with overhangs > 45°).
The first printing attempts should be without a supporting brim since the result here is usually better again.
83
Filament Settings
(1) Filament diameter and filament diameter tolerances according to the manufacturer specification are set here. If no
manufacturer’s
specification is present, these values can also be measured with a calliper (measure 1 m of filament material
in 10 dierent points and then set the average here).
(2) Temperature settings for extruder and heating bed separated by first and all other layers.
Observe the settings recommended by the filament manufacturer!
Since the best values may fluctuate extremely depending on the filament manufacturer, perform your own tests based on
the pre-settings to achieve the best printing quality. When performing the tests, proceed in 5 °C steps and compare the
results during or after printing with other settings. The first layer should always be printed a little more hotly for better
adhesion on the heating plate.
(1) Here you can choose between automatic cooling and permanent operation of the fan at the extruder.
(2) Setting
of the fan speed.

(1) The starting code contains the first commands that the 3D printer performs. Here, e.g. a Z-compensation can be started.
The Z compensation is unnecessary if the distance between the extruder nozzle and heating plate is set manually with the
buttons of the operating fields (as described before when starting a printing process).
Procedure
for determination of the correct command:
Move the printer to the home position.
Switch o the motors and return to the main menu display.
Move the extruder and the heating plate so that the extruder is placed centrally above the heating plate.
Place a normal, singly folded printer paper (80 g/m²) between the extruder and heating plate.
Move
the heating plate with the buttons for the heating plate movement up until the paper can just be moved. A distance of
approx. 0.2 mm is set here.
Do not move the heating plate up too far. Danger of breaking the heating plate!
Read the printing plate oset from the home position in the display (Z value in the second display line).
Convert
the oset read to motor steps according to the following formula:
642 x distance value = number of steps to be set
Example: Your measured -0.27 mm >> 642 x (-0.27) = -173.34 steps (also about -173 steps)
This means that the starting code must be moved up by 173 steps (- => up / + => down)
The Z-compensation command then would be:
M3000
M3004 S-173 (-173 is the number of the determined steps for the Z-motor)
(2) The end code will be performed at the end of the print and could contain, e.g. the run into a removal position for the printed
object.
Detailed information on the G-Codes can be found, e.g., in http://reprap.org/wiki/G-code
86
(1) Setting of the nozzle diameter
(2) Settings for the filament withdrawal if the extruder moves to another position of the printed object during printing. If the
filament was not withdrawn here, there would be drop or string formation that would negatively influence printing quality.
16. Software “Cura”
a) General Notes on Software
It is unfortunately not possible to explain the complete function of the “Cura” software in the scope of this instruction. We refer to
the instructions and the forum under www.ultimaker.com.
The basic operation and the path to the first printout are, however, described below to that you can get a result quickly and
easily.
To further facilitate this, we have collected some printer and material-specific configuration files for the software that are enclo
-
sed on the included SD card.
Cura
is another high-performance software solution for 3D printing that is easy to operate even for beginners.
b) Installation
Download the software from www.ultimaker.com.
Install the setup file that you have downloaded.
If during installation the operating system shows a message according to which the driver has not passed the Windows logo
test, choose “Continue installation”.
87
c) Setup of the Software
Connect the 3D printer to a free USB interface of the computer and switch it on.
If the printer has not been connected to the computer before, the operating system recognises new hardware and is looking for
the corresponding driver.
Select
manual driver selection and enter the directory.
The printer driver is in a subdirectory of the directory “Arduino” on the enclosed SD card (just open the folders and
subfolders in the “Arduino” directory until the directory “drivers” is displayed).
If during installation the operating system shows a message according to which the driver has not passed the Windows logo
test, choose “Continue installation”.
Start the software.
The “Configuration Wizard”, which will guide you through the setup process of the 3D printer, appears:
(1) Click
“Next”.
88
(1) Select “Other” in the next window.
(2) Confirm the selection with “Next”
(1) Select
“Custom...” in the next window.
(2) Confirm the selection with “Next”
89
(1) Enter the values shown in the figure in the field on the following screen.
(2) Click “Finish” to complete the wizard.
The software starts and there is already an object on the printing area.
(1) Click
“File”
(2) Select “Machine settings”
90
(1) Select the serial port to which your printer is connected.
The port number is system-dependent. You can find it in the device manager of the control panel, under connections
(COM and LPT).
(2) Set the baud rate as shown.
(3) Click “OK” to save the changes.
(1) Click
“File”.
(2) Select “Open Profile”.
Select a filament configuration file for the filament used by you in the selection window and confirm your selection.
You can find the configuration file “Settings.ini” on the enclosed SD card in the folder “Cura”. Alternatively, you can skip
this step. The software then uses its own basic settings that are sucient for the first print.
91
d) Use of the Software in the Quickprint Mode
(1) Click “Expert”.
(2) Select “Switch to quick print...”
The
software interface is now simplified and only very few settings need to be made before printing.
This surface is ideal for producing the first test prints and familiarising yourself with the software settings and the resulting
changes.
In Quickprint mode, start and end G-Codes or Z-calibration are not supported. These settings are, ho
-
wever available in expert mode (for more information, see the instructions and the forum under
www.ultimaker.com).
Try printing the object already on the software printing plate with dierent settings and inspect the dierent results.
Find some information on the possible settings enclosed:
(1) Selection of the printing quality (the higher, the slower the print)
(2) Selection
of the filament material and filament diameter
(3) With the field activated, supporting structures are printed as well (required when printing out with overhangs, e.g. for
bridges)

17. Filament Change
Before filament change, the extruder must be heated so that the old filament can be cleanly replaced from the extruder.
Do not touch the hot extruder nozzle when replacing the filament, danger of burns!
Always wait for the extruder temperature to be reached at filament change and let the extruder heat for approx. ano
-
ther minute, since the extruder may break otherwise.
(1) Switch on the extruder heating.
(2) Set a temperature suitable for the inserted filament material (ABS: 270 °C / PLA 230 °C).
(3) When the temperature is reached, let the extruder heat for approx. another minute and then move the filament material out
of
the extruder with the manual control:
“Extrude” moves material into the extruder, “Move in” pulls the filament from the extruder.
Here, speed and length of the material that is being conveyed per mouse click can be set.
After
the old filament has been removed from the extruder, you can pull it out of the filament hose and insert the new filament.
Then
proceed as described for “Initial Commissioning”, in “Inserting the Filament” to insert the new filament.
Use the manual control of the software again and let enough material extrude until the residue of the old material has completely
escaped form the extruder (can be recognised by the colour change).
Switch o the extruder heating again and have the extruder cool o.
95
18. Firmware Update
The firmware is updated frequently to optimise the properties of the 3D printer.
The currently installed firmware version of your printer is briefly displayed in the upper display line after switching on the printer.
For firmware updates, see https://github.com/RF1000/Repetier-Firmware. Here, the most recent firmware updates are
provided. You can choose between two “branches”:
“Master” is the final version of the firmware.
“Development” is the version of the firmware that is currently subject to development.
The firmware link can also be reached in the custom software Repetier-Host under “Help” > “RF1000 Firmware”.
Update
process
The printer must be connected to the USB interface of the computer and must not be connected to any other software
(for Repetier-Host, e.g. click “Separate”).
Download the corresponding update file and save it on your computer.
Execute
the file arduino.exe, which is on the enclosed SD-card (folder “Arduino” and its version subfolders until you find the file
“arduino.exe”.
A window opens
In the menu “Tools”, select the option “Board” and set the type “Arduino Mega 2560 or Mega ADK”.
96
In the menu “Tools”, select the option “Serial port” and set the correct port.
The port number is system-dependent. You can find it in the device manager of the control panel, under connections
(COM and LPT).
In the menu “File”, choose the option “Open...” and select the file “repetier.ino” from the downloaded firmware folder.
The file “repetier.ino” can be found via the following file path: “Repetier-Firmware-master\src\ArduinoAVR\Repetier”
97
A new window opens.
Click “Upload” in the menu “File” here to transfer to the new firmware to the 3D printer.
After
a successful firmware update, the 3D-printer will start again and briefly display the new firmware version in the first dis
-
play line after the start.
19. Maintenance
a) General Information
Periodically verify the technical safety of the 3D printer, e.g. check for damage to the mains cable and the casing.
If you have reason to believe that the device can no longer be operated safely, disconnect it immediately and make sure it is not
operated unintentionally. Pull the mains plug from the mains socket!
It
can be assumed that safe operation is no longer possible if:
the device is visibly damaged
the device no longer works
the device has been stored under unfavourable conditions for an extended period of time or
after exposure to extraordinary stress caused by transport
Always
observe the following safety information before cleaning or servicing the 3D printer:
Live components may be exposed if covers are opened or components are removed.
The device must be disconnected from all power sources before any servicing or repair work is carried out.
Capacitors inside the device may still carry voltage even though they have been disconnected from all power sour
-
ces.
Only qualified experts familiar with the hazards involved and the relevant regulations must perform repairs.
98
b) Cleaning
Device
The outside of the 3D printer should only be cleaned with a soft, dry cloth or brush.
Never use any aggressive cleaning agents or chemical solutions on plastic parts, stickers or the display since these
parts would be damaged otherwise.
Nozzle
cleaning
Caution: Danger of burns. Do not touch the hot nozzle directly.
Outside cleaning of the nozzle:
Carefully
wipe o the extruder nozzle after each print using tissue paper or similar.
The nozzle still has to be hot for this. If this is not the case, heat up the extruder nozzle first.
Inner cleaning of the nozzle:
Heat up the extruder and actuate the manual feed forward and backward several times until enough filament is extruded.
If
the extruder continues not to extrude enough material after this procedure, let the extruder cool o to the lower melt tempe
-
rature of the filament as indicated by the manufacturer (filament material must only be viscous anymore) and carefully confirm
manual infeed backwards until the filament has been transported out of the extruder, including contamination. Cut o the conta
-
minated part of the filament and reinsert it after heating up the extruder again.
Cleaning
the heating plate
Caution: Danger of burns. Let the heating plate cool o before cleaning.
Clean and degrease the heating plate thoroughly with a soft rag and some acetone after each print.
c) Fuse Replacement
If you have to replace the fuse, ensure that you only use fuses of the specified type and rated current (see “Technical Data”) as
a replacement.
Never repair fuses or bridge the fuse holder.
Unplug the mains plug from the mains socket and disconnect the low-voltage line from the low power device combination so
-
cket at the rear of the device.
Using a suitable screwdriver to push the fuse holder out of the low power device combination socket carefully.
Remove
the defective fuse and replace it with a new fuse of the indicated type.
Carefully push the fuse holder with the new fuse back into the low power device combination socket at the device.
After this, you can reconnect the device to the mains voltage and take it into operation.
d) Checking the Belt Tension
Check the tension of the drive belts now and then.
If required, retention them by setting the belt tensioner with the setting screws so that the toothed belts can still be twisted by
180° easily with two fingers.
The toothed belts must not be tensioned too strongly. If a belt tensioner bends, the belt tension must be reduced under
all circumstances.
99
Method for precise setting of the belt tension
For this, you need a weight of 1 kg, such as a water bottle filled with water to reach the specified weight of 1 kg. You also need a
cord for attachment.
Fasten the heating plate with adhesive tape or similar first to keep it from falling out and being damaged if the printer
tips.
Place a soft support under the printer so that it is not scratched when tipping and so that it cannot damage the table
top.
Now tip the printer to its front near the edge of the table and
attach the weight to the part of the toothed belt for the X-direc
-
tion that is now at the bottom using the cord.
The weight must be suspended so that it can move freely.
Measure the distance between the two toothed belt halves as
shown in the figure. Set a distance of 28 mm with the belt ten
-
sioner.
Now tip the printer to the right side near the edge of the table
and attach the weight to the part of the toothed belt for the Y-
direction that is now at the bottom using the cord.
The weight must be suspended so that it can move freely. For
this, it must be threaded through an opening in the side part
near the right threaded circulation spindle.
Measure the distance between the two toothed belt halves as
shown in the figure. Set a distance of 30 mm with the belt ten
-
sioner.
100
Tip the printer onto its back close to the edge of the table and
remove the bottom sheet.
Attach the weight to the part of the toothed belt for the Z-direc
-
tion that is now at the top with the cord.
The weight must be suspended to be freely movable but may
touch the mains unit housing. This is not a problem.
Measure the distance between the two toothed belt halves as
shown in the figure. Set a distance of 41 mm with the belt ten-
sioner.
101
e) Nozzle Change
Caution: Danger of burns. Do not touch the hot nozzle or the extruder directly.
To replace the extruder nozzle, the extruder must first be heated to a temperature suitable for the inserted filament material.
When
the temperature is reached, remove the inserted filament material as described in “Filament Change”.
Screw o the extruder nozzle (1) from the extruder with a 10 mm hexagon wrench (2). Always secure the extruder against twi
-
sting at the flattened area of the nozzle thread above the nozzle with the enclosed nozzle wrench (3).
The extruder must not twist during nozzle change and the nozzle must never be turned when cold since the cement
layer above the nozzle may break otherwise. This will render the extruder useless.
Clean the thread at the extruder of filament residue (e.g. with a brass brush).
Coil
a piece of sealing tape of about 5 cm around the nozzle thread at the extruder and carefully screw the new nozzle onto the
extruder. Secure the extruder against twisting again with the enclosed nozzle wrench.
Do not wrap the sealing tape beyond the nozzle thread since the nozzle will clog otherwise. We recommend our PTFE
high-temperature tape from the accessory programme of the 3D printer.
Carefully screw in the new extruder nozzle. Never apply any strong forces for this.
Then insert the filament again as described in “Filament Change”.
Switch o the extruder heating again and have the extruder cool o.
20. Handling
Never connect the mains plug to a mains socket immediately after the device has been taken from a cold to a warm environ-
ment. The resulting condensation may destroy the device. Allow the device to reach room temperature before connecting it.
Wait until the condensation has evaporated.
Never pull the mains plug from the mains socket by the cable. Only pull it from the mains socket by the intended grip areas.
Disconnect the 3D printer from the mains voltage if you are not going to use it for an extended period of time.
Disconnect the mains plug from the mains socket during thunderstorms for reasons of safety.
The heating plate and extruder may heat up strongly in operation. Do not touch these parts during or just after operation. Let
these parts cool o first.
102
21. Troubleshooting
With this 3D printer, you have purchased a product that is built to the state of the art and operationally safe.
Nevertheless, problems or errors may occur. Therefore, we would like to describe how to eliminate possible errors here:
Always observe the safety information!
The 3D printer does not work after switching on. The display and print space lighting remain dark:
Check
the connection of the mains line.
Check the mains socket. Is it properly supplied with current?
Check the mains fuse (also see “Fuse change” in chapter “Maintenance”).
No USB connection to the 3D printer is possible:
Check
the USB line connection.
Is the right USB port selected in the software?
Are the required drivers installed?
Unplug the USB line and then plug it in again.
Start the software again.
Switch the 3D printer o and on again.
Start
the computer again.
Use another USB port.
Connect the 3D printer directly to a USB port of the computer. Do not use any USB hub.
Calibration of the heating plate stops. The display shows the message “Scan aborted”:
Heat
the extruder to melting temperature of the inserted filament and transport the filament a few steps backwards out of the
extruder. The filament must not cause any forces to be exerted on the extruder but the ball bearing holder still must be loaded
by the filament.
The extruder nozzle must be clean from the outside (if required, heat and wipe o first – caution: hot nozzle!)
Perform the basic settings of the limit switch for the Z-direction again. The plate distance must not be too large.
The
pressure sensors may have been installed under tension. In this case, loosen the screws of the print sensors and then
retighten them evenly.
The print has defects:
Check
the extruder and heating bed temperature settings. They must match the filament material and print object. Experiment
with the temperature settings in steps of 5 °C for a prefect print result.
Only start the print when the extruder and the heating bed have reached the specified temperature.
The distance between the heating plate and extruder is set incorrectly. Perform Z calibration or set the distance more precisely
when starting the print using the buttons at the 3D printer.
When
printing from the PC, do not use any other programmes requiring high computing power. Virus scanners and downloads
may also impair signal transfer to the 3D printer. Try performing the same print from the SD card to ensure that the USB connec
-
tion is not the cause of the problems.
103
The filament supply breaks o or there is not enough filament material supplied:
Check the filament unroller. It must turn easily.
Check whether the filament material has caught on the filament unroller. The filament hose at the filament roller may have
caught.
Some filament types do not slide through the filament hose properly. If required, use the alternative filament holder that you can
print from the SD card (file name “Filament_guide.gcode”).
The
set extruder temperature is too low for the filament material used. The feed knurl slips at the filament material.
Check whether the feed knurl slips on the motor axis of the extruder motor. The grub screw may have come loose. If the feed
knurl slips in spite of the grub screw being tightened, use a grub screw with a point or slightly file down the motor axis in the
area of the grub screw to reduce slippage.
The
clamping spring screws at the filament feed are not tightened well enough. Therefore, the drive slips.
Check that the filament material runs into the extruder from above cleanly. It must be able to run past the extruder motor from
above and into the bore of the extruder without scraping or clamping anywhere. If this is not the case, loosen the nut at the
extruder and the screws at the feed basic part and align the parts so that the filament is cleanly inserted into the extruder.
The
extruder nozzle is clogged. Heat up the extruder and actuate the manual feed forward and backward several times until
enough filament is extruded.
Let the extruder cool down to just below the melt temperature specified by the manufacturer for the filament (filament material
must only be viscous anymore) and carefully actuate the manual feed backwards until the filament with contamination has been
removed from the extruder. Cut o the contaminated part of the filament and reinsert it after heating up the extruder again.
Printing stops during the process:
Check the settings of your computer. It must not switch to standby mode while printing (energy option settings) or simply shut
down (installation of software or software updates during printing).
If the value measured by the printing sensors at the extruder exceeds a threshold, the printer will automatically switch to pau
-
se mode for reasons of safety. Printing can be started again by pushing the button for continuing printing (play button). If this
happens frequently, the print sensors are installed under tension. In this case, loosen the screws of the print sensors and then
retighten them evenly.
The printed object does not adhere to the heating plate:
The
temperature of the heating plate is set incorrectly. Experiment with the temperature settings in steps of 5 °C for a prefect
print result.
When printing problematic objects, it is beneficial to let the heating plate heat up for approx. 15 minutes before printing.
Check whether the heating (red foam material) adheres cleanly to the ceramics printing plate. It must not come loose (even
partially). If this is the case, the temperature distribution of the heating plate is insucient and the printed objects cannot adhere
well.
There are residues on the heating plate that prevent adhesion of the object. Rub the heating plate with a soft cloth that is soaked
with a solvent (e.g. acetone).
The
heating plate has not reached the set temperature yet.
At PLA printing of small objects with a small footprint, it is recommended to apply the heating plate with cleaning tape or a
slightly structured crepe tape before printing. This increases adhesion of the printed object on the base plate.
The
printed object cannot be removed from the heating plate:
Wait until the heating plate has cooled down to less than 40 °C.
Use a painter’s spatula or a knife to remove the object.
Repairs other than those described above should only be carried out by an authorised specialist.

b) Notes on the Print Files (GCODE Files) on the Enclosed SD Card
The folder “GCODE” on the enclosed SD card holds various finished printing files.
These files do not need to be sliced with a software like the Repetier-Host first. They can be printed right from the SD card (also
see “First Print of an Example Object from the SD Card”).
The
files are saved in the folder “ABS” and “PLA”, depending on the filament type used.
Example: Heart.gcode in the folder ABS = small heart for printing with ABS filament

This chapter is only targeted at users who do not have the custom version of the software installed. If you have instal
-
led the custom version (can be recognised by the image of the RF1000 3D-printer when the programme starts), you may
skip this chapter. It only serves information purposes then.
The folder “Slic3r Settings” on the enclosed SD-card contains dierent configuration files (.ini-files) for the basic version of the
software Repetier-Host.
If you have installed the custom version adjusted for the RF1000 of the Repetier-Host software, configuration files are already
integrated into the software.
The files are designated as follows:
Printer name_Filament material_Layer thickness_Nozzle diameter.ini
Example:
RF1000_ABS300_100_05.ini = Printer RF1000_Filament 3mm ABS_Layer thickness 100 µm (=0.1 mm)_Nozzle Diameter 0.5 mm
The option VASE permits printing of objects with filling (e.g. cylinder) as hollow bodies without having to produce the
corresponding 3D file for it.
If a cylinder-shaped body is printed with the option VASE, the resulting object has a bottom plate and a thin outer wall
(like a vase).
e) Setting up the Slicer
This chapter is only targeted at users who do not have the custom version of the software installed. If you have instal
-
led the custom version (can be recognised by the image of the RF1000 3D-printer when the programme starts), you can
