Underextrusion after mishap
I've had my mini for about a month. Yesterday I switched from the powder-coated plate to the PEI and - like an idiot - neglected to adjust Z before printing & then took my eye off the ball. Heard a strange noise from the printer less than a minute later & returned my attention - observed that the nozzle was actually touching the plate and was so low it had scratched it in several places. Cursed robustly and stopped the print immediately. Now, I have an underextrusion issue. We've gone through all the steps on the underextrusion troubleshooting page, plus cold pulls - no change. Even dried out the filament in case it was a moisture coincidence. Anyone have thoughts on further things to try or what precisely could be damaged / need replacement?
RE: Underextrusion after mishap
I have had similar experience. I started having jams and under-extrusion between rolls and when changing rolls.
I cleaning cleaning filament and now no problem. Nova cleaning filament.
