Troubleshooting
Here follow the issues we usually deal with: knowing the answer in advance my save you precious time!
#1 – Little or no extrusion
•
Filament has quality issues (diameter is bigger than 3.1mm or smaller than2.6mm, polymer purity problems,
filament is contaminated with powder/dust)
Check filament diameter, if needed discard the spool
•
Nozzle partially jammed
Clean nozzle or swap it with a new one
•
Wrong slicer settings for the filament (usually: extruder not hot enough, printing speed too fast)
Check your slicing setting, be sure to use right ones for current polymer
•
Dirty feeding roller – filament is sliding on it
Clean the feeding roller
•
Insufficient feeding pressure
Increase feeding pressure (using the knob)
•
Extruder has electrical issues
Check the connector to be fully seated
Check cable integrity
You may want to change extruder for a new one
•
Feeding roller setting screw is loose
Tighten it using a 2mm hex key
#2 – Part won't stick to the plate
•
Plate is dirty
Clean the plate using Acetone (when printing ABS) or alcohol-based cleaners (PLA) or just with warm water and
soap (PA) to remove fingerprints, glue leftovers and other adhesion improvement substances
•
Z offset is too big
Decrease Z offset setting in your slicer
•
First layer speed is too high
Decrease first layer speed in your slicer settings
•
Polymer in use is not compatible with printing bed surface
Change surface or use an adhesion improvement product (hairspray or any other product)
•
Printing plate is too cold
Increase thermal settings (plate and heated chamber)
•
Part has very small “foot area” compared to height
Decrease printing speed
Increase layer thickness
Enlarge support / use brim
Check alternative part orientation
