11 FAQ(Frequently Asked Questions)

11.1 Abnormal extrusion

1) The filament is tangled. The nozzle temp is too low to reach the melting temperature
required.
2) There is carbonized residue inside the nozzle.
3) Please replace it with the spare nozzle. Insufficient heat dissipation of radiator of the
extruder head causes the filament in the tube to melt in advance and the extrusion strength
is insufficient. Please check whether the cooling fan works normally.
4) The slicing speed is so fast that the nozzle speeding can't match it. Please reduce the printing
speed.
5) Be sure the smooth in extruder inside after long-time printing. Please keep clean on a regular
basis avoiding plugging.
11.2 The gear of the extruder skips and makes an abnormal
noise
1) The nozzle is clogged; please refer to 11.1 abnormal extrusion.
2) Check whether the friction force between the extruder gear and the filament is enough.
Please clean the residue.
3) Check whether the voltage of the driver (Vref) of the extruder is normal, and try to
increase it by 0.1v until it works normally, max 1.2v.

11.3 First layer abnormal

1) Non-stick: a. the nozzle is too far from the hot bed. Please re-level the bed, try to stick
masking paper or glue stick on the surface of the hot bed.
2) Not extruding and the bed scratched: a. the nozzle is too close from the hot bed. Please
re-level the bed; b. check if the nozzle extrusion normal.

11.4 Layer shift

1) The printing speed is too fast. Please slow it down.
2) The belt of X or Y axis is too loose. Please tighten it.
3) The X or Y axis synchronization wheel is not fixed firmly. Please adjust the eccentric nuts.
4) The voltage of the driver of X/Y axis is too low.
