Troubleshooting
Possible Solution
1. Inspect/replace if at fault.
2. Ensure correct power supply voltage, circuit size,
and machine is properly connected.
3. Ensure circuit is sized correctly and free of shorts.
Reset circuit breaker or replace fuse.
4. Fix broken wires or disconnected/corroded
connections.
5. Inspect/replace if at fault.
1. Tension/replace belt(s); ensure sprockets are
aligned (Page 42).
2. Wire motor correctly (Page 44).

4. Test/repair/replace.
5. Test/repair/replace.
1. Test/repair/replace.
2. Tighten motor to chassis.
3. Test/repair/replace.
Possible Solution
1. Level build plate (Page 24).
2. Increase temperature and restart preheating
process (Page 26).
3. Unwind filament from spool until it is not tangled or
overlapping.
4. Clean (Page 36) or replace (Page 40) nozzle.
5. Test/repair/replace.
6. Test/repair/replace.
7. Test/repair/replace.
1. Level build plate (Page 24).
2. Clean build plate, then re-apply adhesive (Page 25).
3. In slicer software, turn on brim, raft, or add
supports.
4. Adjust temperature and restart preheating process
(Page 26). Lower temperature may require slower
print speed.
5. In slicer software, reduce travel speed.
