Ten: Trouble Shooting
Question 1
layer shifting
Answer 1
Print speed is too fast, change your print speed to 30mm/s – 60mm/s.
The bell pully or bell might be loosened. Tighten them up.
The Stepper motor is missing steps. The current through the motor might be too
small so that the stepper motor doesn’t have enough torque. Increase the output
voltage from the stepper driver to increase the power of the stepper motor.
The stepper, stepper driver and the power supply might be overheated.
Overheating might affect the performance of steppers.
Question 2
Filament leak
Answer 2
The nozzle is not tightened. Heat up the nozzle and remove the filament before
tightening the nozzle with a plier. Do not touch the heated nozzle with your hand!
Question 3
Difficult to install filament
Answer 3
Straighten the end of the filament with your hand, and cut the very end of the
filament to a 45 degrees angle with plier
The screw on the extruder is too tight, slightly loosen it.
Filament jam in the white filament tube, heat up to 220 degree and remove the
jam filament
Question 4
Bobbling on the top of the print
Answer 4
Insufficient cooling is possible, make sure the fan is working.
Top layer height is too thin, increase top layer height in your print setting.
Question 5
Inconsistent extrusion
Answer 5
Check and see if the filament is jammed
Check and see if there is a nozzle jam
Double check if you are using the correct layer height and filament size setting
You might be using low quality filament that would often breaks.
Question 6
Stringing
Answer 6
Change the retraction distance and retraction speed.
Adjust the retraction setting by 1mm each time and compare the result.
Try lowering the print temperature by 5 degrees each time.
Lower the travel distance. Lower the distance between each model if you are
printing multiple models a time.
Question 7
Computer can not recognize the printer
