Check plate cleanliness, selected build surface, bed calibration, temperature and relevant printer instructions.
SOLVE / TROUBLESHOOTING
Review likely causes one by one instead of changing every setting at the same time.
Check plate cleanliness, selected build surface, bed calibration, temperature and relevant printer instructions.
Review moisture, temperature, travel moves and retraction only where your extrusion system supports adjustment.
Often involves thermal contraction, bed adhesion and ambient conditions.
Consider collisions, mechanical resistance, movement system condition and acceleration settings.
Investigate material choice, moisture, temperature, flow and part orientation before changing infill.
Adjust orientation, support geometry and interface settings for your nozzle, layer height and filament.
Safety: Do not modify electrical wiring, power supplies or heating circuits without appropriate expertise. Follow the manufacturer’s maintenance procedures first.
