when it is too close and too far?
A: The standard distance between the nozzle and printing bed is the thickness of a piece of A4
paper, Insert a piece of paper between the bed and the nozzle, with normal pull and with resistance
as the standard in the condition that do not scratch bed. The closer it is, the firmer the model will
be.
(1) The right distance between nozzle and bed: the ”silks” are flat, spread on bed very smooth
and no burrs.
(2) The distance is too far: the “silks” are fine round, spread on bed unevenly, with gaps and tilt.
filament come down to the bed is by gravity force. The rounded strips’ adhesion effect is not good,
they are easily moved. Printing effect is very unsatisfactory.
(3) The distance is too close: the “silks” are irregular protrusion(with burrs)on the both sides, but
thin in the middle. Or there are no silks coming down. Or the bed is scratched with a deep trace .
Q7: Why do there twist lots of filament nearby the nozzle in the process of printing? Model become
mess of silks?
A: There are several situation:
(1) When it happens in the initial printing, the distance between nozzle and bed is too far, the
silks cannot stick to the bed ,so it would become messy filament. Please twist the 4 bed screws 90
degree anti-clockwise. If still not ok , then please twist 90 degree anti-clockwise again till normal
printing.
(2) The bed is with oil, please use dry towel to tidy the bed, do not use hand to touch the bed
directly.
Q8: How can I move the printing head?
A: Please unplug the power ,then use hand to move the printing head to where you want. Please
do not try to move the head up and down, move along Z axis cannot realized by hand.
Q9: How can I move the printing head up?
A: Only in the condition that the printer is power on but is not working, press the printing button
for 3 seconds then release, it will goes up 1 cm.
Q10: Does the printer need warming up before each printing?
A: There needs to warm up when feed and retract operation, In the normal printing, you only need
to choose the model and wait about 1 minute, then printer will start work.
