I formatted the USB stick (full format), and that seems to have fixed the issue.

Getting the same error now, about the USB being full (there's still plenty of room on it). I'll try a format when it's done with the current print.

Did you format the stick with FAT32, and a full format (not quick format)?

I'm having USB flash drive issues after the upgrade. First, i put the firmware on the flash drive and rebooted the printer. It did not do the firmware upgrade. When I put the flash drive back in my Windows PC, it would no longer read the drive. I put it back in the printer and all my gcode files still showed up, so I just left it there and uploaded files via Prusalink. Then last night I got an out of space error when attempting to upload a model for printing. I tried deleting files but that did not work. I then used my PC to completely wipe the drive and reformat it. That worked for one print, but now I'm getting this message from Prusaslicer:

Prusaslicer has encountered an error

Upload has failed. There is no suitable storage found at x.x.x.x.

Timeout was reached:

It's very odd that your printer has this issue and other printers do not.

I would agree - my Mk4 was purchased ready-built and has not been modified.

Loaded 6.0.1, everything back to normal, no 'stuck filament' errors.

Clearly, someone has changed whatever parameter looks for 'stuck filament' without mentioning the change in the changelog and without giving anyone else, i.e. the user, any chance of changing whatever parameter was changed back to whatever it was in 6.0.1.

Also, on the initial start of a print I thought (with 6.1.2) that the print head was going to slam into the bed considering the speed it was dropping, compared to 6.0.1, however, the print head did stop and do it's normal thing, but, again, the change didn't make it into the changelog (haven't tried 6.0.2, 6.0.3 or 6.0.4).

Loaded 6.1.2 and now I'm getting 'stuck filament' errors, which I 've never had before.

Looks like it's back to 6.0.1 which I know works with no problem.

I'm running 6.1.2 on my MK4 with a newly built MMU3, no issues so far!
