I have x1c for 1 week now and first 3 days the quality was out of the world but then i started getting weird finish its not smooth anymore tried recalibrating tightening belts cold pulls on the nozzle but nothing seems to help…
Something has changed…
If you reprint an old model that previously worked well, does it show the same issues?
Try to identify what might have changed — the answer could lie there.
Already tried that and the issue remains even on an old part that was ok before with the same roll of filament…
If everything is the same — same spool, same G-code, same printer — and the print suddenly starts failing or shows weak layer bonding, this is what I would try to troubleshoot the issue:
1. Dry the filament – Even if it’s the same spool that previously worked, ambient humidity can still affect it over time. A thorough drying cycle can often restore print quality.
2. Check for a partially clogged nozzle – These can be deceptive. The first layers may look fine, but a restriction builds up and causes under-extrusion later on. I would either run a cold pull or just swap to a clean nozzle to rule it out.
Those two steps solve most unexpected extrusion issues for me.
Does it also appear on the upper end of the print or only near the buildplate?
