so up until today my P1P was printing perfectly. No trouble whatsoever. But starting today, I have a very weird thing happening on every print, essentially rendering each print useless.
When I start printing and after the bed leveling is done, the printer prints a line (as always). However, the beginning of the line is skipped. It continues over to the first position, leaving a trail of filament along the way. As soon as it goes down to print, I get a bubble, then it starts moving and I get nothing. After about 2cm, it starts drawing a line again. As it goes back to the beginning of the next line, same thing is happening. I am a beginner and don’t know how to troubleshoot this. Does anybody know, what is happening?
Edit: Thought, it may be a temperature problem. Checked with PETG print at 250°, same problem, if not worse. (Last picture)
Edit 2: I also realised, that the fan in front on the hot end (hot end fan?) is not spinning at all.
