Troubleshooting
Most likely to least likely:
- Extruder
- Stuttering:
- 4-pin connector on the board needs reseated (unplug, replug).
- Not Extruding:
- Idler tension too tight (digs hole in PLA) or too lose.
- Uneven Extrusion:
- Gears not making proper contact. There is currently a black plate between the extruder motor and chassis in order to keep the gears flush.
- Idler not doing it's job.
- Cold Extrusion Prevented:
- If this occurs before a print, you can warm the tip manually with your hand until it reaches a temperature where it will set temp. You can fix this forever by reflashing the min temp for extrusion in the firmware.
- Chassis
- Prints not filling properly and/or skewed lines in XY:
- Gears on X/Y motors have come loose, and need reseated and tightened on the flush part of the motor shaft.
- Belts are too lose.
- Gears on the motors are bad and the belts are slipping on them.
- Prints are lopsided:
- Bed is uneven. The bed is very finnicky and does not always sit perfectly flat on the rails, raising in one corner (usually back left). Secure the bed.
- First layer not smashed enough:
- Z-axis home is not close enough to the bed. This can be adjusted during the print by twisting the Z-rods but home position should be adjusted.
- The settings in slicer are not using a 120% fill for the first layer (as opposed to 100% for normal layers).
