Mini+ firmware 5.1.2 not working again
After a few days of working just fine with .bgcode files, firmware 5.1.2/PrusaSlicer 2.7.1 is not working again. When I upload .bgcode files to a stick and put that into the printer, the stick is recognized, but no file is listed. Same when I upload .gcode files. I would love to go back to an earlier firmware and PrusaSlicer, but I haven't been able to find a way to do that. Has anyone else experienced this instability in 5.1.2? What are my options to get my printer working again?

No problem on my end. To downgrade, copy the firmware to the stick and hold down the knob while booting.

Well, mea culpa, I guess. As they say: "I have met the enemy, and he is me". Turns out I had a .stl file with a filename that started with a period (actually a decimal place as part of a number, without a leading 0). Windows was fine with that, and PrusaSlicer running on Windows had no problem opening it and creating a .bgcode file from it. But the file name sent to the printer started with that period, and the firmware choked on that (it simple did not recognize the file was on the USB drive). In the best of worlds, PrusaSlicer would have flagged it as a non-conforming filename, although Windows seems to allow it. Linux may not allow it, I presume. Thanks, fuchsr, for the guidance on how to go back to an earlier firmware, but I'm a happy camper now with 5.1.2.

Under Linux filenames starting with a dot are treated as hidden, so they are not presented in the listing if not requested.
Not sure if firmware allows showing hidden filenames, though.
See my GitHub and printables.com for some 3d stuff that you may like.

I upgraded to slicer 2.7.2 and Mini 5.1.2 and the printer kept having hang problems with bg code. After a couple of hours reverting to to previous levels and only now supporting g code the slicer and printer is working fine. I think the upgrade is too buggy for prime time.
