Question 3: When the machine returns the filament, it can't be
returned. What should I do when stuck in the pneumatic joint?
Question 4: What should I do if I cannot resume printing after
power shutdown?
1. Before returning the material, please
heat the nozzle first, and then withdraw
the consumables as soon as possible. If
you can't pump it, you can re-feed the
material with the advanced material,
and melt the extruded block formed at
the end of the consumable in the
nozzle.
2. When withdrawing the
consumables, before the end of
the consumables reaches the
pneumatic joint, we will usually
pull the Teflon directly from the
Teflon and cut the end of the
consumables.
3. Because the end of the
consumables in the nozzle will be
deformed by heat, if the end
deformed consumables are directly
pulled out, it may be stuck to the
pneumatic joint or the limit switch for
damage detection. (The limit switch
for the broken material detection is
single. Towards).
If the power is suddenly turned off when the part is first printed, the machine
will not save the print data. Unless the height of the print exceeds 0.5mm, the
power failure will be supported. If the height is less than 0.5mm, it is
recommended to reprint directly.
