1. Reorient, reprocess and resubmit the part
2. Run Z calibration
3. Replace tip shields and tip wipe assembly
4. If part has shifted in X or Y, refer to part quality section, part shift subsection.
5. In case of Z shift:
a. Realign Z guide rods.
b. Replace Z motor and leadscrew.

damage.
4. Check to make sure head blower fan hose is connected to blower.
5. If extrusion fails on first layer with a used modeling base, retry with a new one
6. Rerun Z calibration
7. Plugged Liquefier - replace tips.
8. Inspect model for excessive overfill.
a. Toolpaths should not overlap by more than 50%. If so, reorient and
reprocess STL.
b. If model curl has caused the part to contact the tip, reprocess part with
less dense fill. Re-run tip Z cal if part is separating from supports
c. If part curl continues, see part curl section
9. Check idler wheel gap.

14. Blower fan not supplying enough air flow - weak or stalling. Replace fan.
15. Replace umbilical cable
16. Replace controller board
17. In case of Z shift:
a. Realign Z guide rods.
b. Replace Z motor and leadscrew.
c. Replace Z assembly.
1. Filament motor is running very
fast.
1. Make sure the head connectors are seated properly.
2. Bad motor. Replace toggle head assembly.
3. Broken wire in the umbilical cable. Replace umbilical cable.
