3.4.0 Filament engine 2.0 problem?
I had an 8ish hour print running, and about 3 hours in my machine started beeping ("that's new" I thought).
I was printing with white filament. The print quality had been really really good so far. I came in to the message that the sensor wasn't reading properly, would I like to disable it. I was not happy, but I said yes. (Also, for reference, I accidentally killed my last filament sensor, this one is only two weeks old. Not dirty.)
Then the print head moved back to the center of the print, but exactly at the last layer height, so it scraped a bit on the nozzle. I gave it the benefit of the doubt and told it to 'resume print' and it proceeded to crash into the print, break it off the surface, and scrape the PINDA probe across the print.
Now I have to re-calibrate the whole thing.
I'm rolling my firmware back until this is improved... It was printing completely fine on the last firmware, and I typically print in black or white, no problems with either.
I like that Prusa is always trying to refine and improve, but maybe this needed more testing or a 'beta' tag before rolling it out and encouraging us all to flash our firmware.
