|'''Issue (symptom)'''
|'''Possible Cause (diagnosis)'''
|'''Potential Fix (cure)'''
|-
|Warping
|Not enough/too much model base surface contact to the print bed
|Add build plate adhesion such as a brim or a raft. Refer to adhesion section for further explanation.
|-
| rowspan="3" |Bad adhesion
|Dirty build plate
|Clean off the build plate first. Debris and oils from your fingers can cause difficulties for the material to stick.
|-
|Not enough/too much model base surface contact to the print bed
|Add build plate adhesion such as a brim or a raft.
|-
|Uneven print bed/Bed too far from nozzle at initial layer
|This is the least likely possibility. Relevel the build plate. Ask a Makerspace staff for more details.
|-
| rowspan="2" |No extrusion
|No filament
|Replace filament spool. Ask a Makerspace staff to replace the filament spool.
|-
|Filament clog
|Keep in mind that it is uncommon that this is the actual cause of lack of extrusion. Ask a Makerspace employee to assist with further diagnosis.
|-
| rowspan="3" |Underextrusion
|The forwarding mechanism (gearbox) ground through the filament
|Move the filament out of the forwarding mechanism. Use the change material feature to speed up the removal. While the mechanism is whirring to remove the material, pull slightly on the filament, at the back of the printer for the mechanism to grab. Break the filament clean off at the section where the filament was ground, clean up the end by cutting it off. Re-forward the material into the printer, making sure the right material is chosen in the menu.
|-
|Wet (very brittle) filament
|Remove wet section of the filament (0.25 to 0.5m length) and re-load. Ask a Makerspace staff for further support.
|-
|Filament clog
|Keep in mind that it is uncommon that this is the actual cause of lack of extrusion. Ask a Makerspace employee to assist with further diagnosis.
|-
|Print not level
|Model not well seated on bed (in slicer)
|Use the snap to bed feature in your slicer (when available), add a brim to preview which flat sections are well seated on the bed
|-
|Drooling
|No supports when needed
|Add supports. Refer to the supports section.
