Printer Crashing on bed mesh leveling
Hello, I have an issue with my Prusa i3/mk3s with it’s leveling. I finished a print over night and then tried to print again this morning. The tool head crashed into the connectors for the headed bed on the y axis, so I did a recalibration, when it would get to the mesh leveling, the second point in the middle of the bed would crash into the bed at the front of the board in the middle. I don’t know what all the sudden it started having fits with me. I just installed a Pi zero w but it worked after I did that. The only thing I did different was print directly to the PI modular from the slicer V2.2. And I just updated the printer firmware 2 days ago. Can someone help me out?
thanks,
Mike

Disconnect all the extras and retry. Once you've ruled out the Rpi isn't the issue then look at other causes. As for "it worked, now it doesn't" - ESD damage is like that. You can damage a device such that it will fail minutes to weeks later.

ESD?
RE: Printer Crashing on bed mesh leveling
Hi, first thing I would do would to check the pinda probe, if its to far away from the bed the nozzle will crash. If it it to close to the nozzle wont go far enough down. If that does not work try reflashing it or factory resetting it.

ElectroStatic Discharge damage ... winter is here, and with it comes dry air that promotes ESD.

That happened to me, definitely could be an issue with the mesh-bed leveling

More info is needed, but if in an enclosure, melted extruder parts are possible; even a warm room can be problematic for a MK3S printing Nylon. The meltdown usually causes the PINDA to droop, but this typically causes the printer to print high requiring frequent Live-Z adjustments, not crash into the bed - but hey, melting plastic does odd things. Check that the PINDA is still vertical and not twisting
Could also be the random ESD near the printer corrupting EEPROM data - this often has gibberish LCD characters as a symptom.
But rereading the OP, flashing new firmware two days ago and the next print failed, sounds like - if there was a power cycle before this most recent fail - the EEPROM contents weren't cleared and reset after the flash. Best practice is to do a full factory reset with the data clear option, then calibrate the printer.

Alrighty I'll do a full reset then. I didn't melt anything from what I can see. I've only printed a could parts and they turned out great. It's just the one deal that it all the sudden acted funny all the sudden. Other than that all the prints have been great
I'll let you guys know if it gets fixed by doing a full reset

Pi Zero is pretty slow, maybe upgrade or use an old PC (I know I'll get flamed for that but if the PC is collecting dust what harm)
RE: Printer Crashing on bed mesh leveling
Rpi 3 or 4 is better than a 0, 1, 2 or even old PC because those can run OctoPrint quite well ...

I took out the Zero W then re-calibrated and it functioned just fine.
I waned the Zero W attached just to play with and experiment with. It also runs off of the power supply from the printer which is why I liked the idea. But I'm going to play around with it a little more.
I have a PI 3B+ that I can use which will work just fine. That is what I was using before and it worked well with no issues.
