Maintenance & Troubleshooting Manual
•
Defective stepper driver (temporary test: swap the Z driver with extruder #3 or #2
•
Z screw movement is irregular: check coupling (screw-motor) and bearings (fully seated into
bottom plate)
•
Dirt trapped on screw nuts: remove any contamination and clean area. Use a clean cloth to remove
any dirt traces from screws. This could be a symptom of hairspray (or any other aerosol
contaminant) being used INSIDE the printer.
•
Broken-defective Z leadscrews/nuts: dismount machine and inspect.
•
Defective Z motor-gearbox
•
Defective motor cabling (loose crimp)

xis Won’t Move
If the selected axis doesn’t move check as follow:
•
Cable from motherboard to stepper motor is OK (fully seated and undamaged)
•
Stepped motor driver is fully seated into motherboard
•
(X or Y) pulley is firmly locked on motor shaft
•
(Z) motherboard fan is running
•
stepper driver current is OK
If above checks are OK, there are three possible reasons:
1)
Faulty stepper driver: swap with a filament feeder driver (upper three topmost positions) and see
if it moves. If yes, be sure to adjust current.
2)
Faulty cable
–
try a temporary replacement with a spare cable (or get one temporary off the
filament feeder)
3)
Faulty stepper motor (VERY, VERY RARE): replace motor
