Corrupted Prints
Every now and then my prints get corrupted, varies but usually I have to reinstall the Pi Deb install to resolve then ok till the next time.
It’s not the GCODE because when I use the same GCODE after reinstall all is ok.
v0.94.3.
Prusa MK3S
I can tell there will be a corruption as soon as the first layer starts printing, very fas 1st perimeter then prints a diagonal line from corner to corner, then.... see photo.

Thanks
Which FW version are you running on your MK3S? I am running version 3.10.0-RC1

Greetings, Patrick
The only thing I see is that the bed seems to be leveled incorrectly. The left front seems to be too high so extruder fails to extruder there. When nozzle is closer to bed it needs more force to extruder and might even fail. Nothing you normally see on a prusa since it autolevels. You can try increasing first layer height or adjust z offset for z probe. The pinda z probe is temperature dependent so you need to compensate for the pinda temperature, which might explain why it only sometimes happens. Don't know how much difference that makes, just read that this is the improvement of the pinda 2 and that firmware detects the type and corrects it based on measured temperature but I think it can also be calibrated. Not sure here.
Normally I would expect the same result with same bed temperature which is the main source to heat up pinda. But I also think it depend on how long you were close to the hot bed before starting.
You might also want to clean the extruder drive so it has more force. If it has lots of debris between teeth it starts loosing force.
Ok that’s an interesting theory but it doesn’t take into account the sometimes very fast movements and the diagonal line across the corners phenomenon.
Also this carried on all the way through the print on the photo I sent you the link of.
That movement does not happen when the print works.
Anyway so far since I’ve turned on ping pong I haven’t had a problem.
