After updating with the latest firmware 3.12.2 the printer keeps showing a message "Self Test Failed"
Hi. I have a Prusa MK3S and Friday May 12 I updated to the new firmware 3.12.2. The printer was working perfectly until the update. Now an error message keeps showing saying that the printer is not yet calibrated, the X axis length is wrong... (I bought pre-assembled!!!) and have been using for 2 years with NO PROBLEM! Tried to go through what the manual says to fix what message says but no luck. This is annoying because I bought it pre-assembled exactly not to have any issues. But something went wrong in this last update and now I'm not able to fix it by myself. Any help would be great.
Thank you.

During the last few weeks many users reported problems of various sorts with this firmware version. I would suggest to just go back to the previous version 3.11.0. You say that worked fine on your printer before (also on mine!). I also went back to this version after I installed a Revo V6 hotend on my MK3S+, as this was the recommended firmware by the manufacturer of the Revo V6.

Well, just an update, I had to roll back to 3.10.1. I haven't had time to test with a print but, at least the self test went through all the way. Thanks.

I have been having extrusion issues. PLA printing from 205 and 202. No issues until update. I am rolling back tonight. But not sure if Firmware or Prusa Slicer version?
Either way reverting firmware and trying again. I have changed out PTFE tube, nozzle, done a cold pull all looking great. Calibration fine but my first layer nozzle just not extruding right. The first "test" line looks great and when high looks like full round extrusion. But when i get down to meet bed roughly -1.45 for me smooth steel plate. i watch it string and have intermittent stings and globs. Here's hoping rollback works.

So i think it was i still wasn't quite close enough for good first layer. Did a lot of research last night, images etc. i lowered from -1.45 to -1.525ish and i was able to print.
Now i just have some small layer issues and "extra" burnt filament that i need to adjust for. Realized all this after my post of course.
Going to re-flash to current version and try again.
Other printer i believe has heat creep and i am going to start troubleshooting that this weekend.
