Print Problem Diagnostic
What does the print actually look like? Pick the closest match below.
Most likely causes, in order
- Retraction distance too short for your extruder type (Bowden vs. direct drive)
- Nozzle temperature at the high end of the filament's range
- Travel speed too slow, giving the nozzle more time to ooze
Most likely causes, in order
- Material with high shrinkage (ABS/ASA) printed without an enclosure
- Bed temperature too low for the material
- Part cooling fan too aggressive on the first several layers
Most likely causes, in order
- Normal staircase texture from layer height, on angled surfaces
- Loose belts or a racked gantry causing regular banding
- Inconsistent extrusion from partial under- or over-extrusion
Most likely causes, in order
- Nozzle too far from the bed (most common cause)
- Bed temperature not matched to the material
- Bed surface needs an adhesive for this specific material
Most likely causes, in order
- Flow rate miscalibrated — run the single-wall test to check which direction
- Nozzle partially clogged (under-extrusion) or worn oversize (over-extrusion)
- Filament diameter different from what the slicer profile assumes
