Cannot send Mk4-MMU3 file stored in Connect Files to MK4 with MMU3  

RE: Cannot send Mk4-MMU3 file stored in Connect Files to MK4 with MMU3

I am having the same issue you describe, printer upgraded to the 6.0.2 firmware.

Posted by: @shapernx

PrusaSlicer - 2.7.4

Prusa Mk4 with MMU3 FirmWare : 6.0.0+14794

I have some files sliced for "MK4ISMMU3" that I store on the Connect-Files but, when  I try to send them to my MK4-MMU3, I have this error:

(note that the printer make is "Mk4 MMU3")

It's like Prusa Connect can't update the printer type with MMU even though the little image is updated for the printer.

Piling on.  Been having this issue for a while.  Upgraded to 6.0.2 yesterday and it continues. Getting really annoying to have to download/upload bgcode files to print them and I don't want to remove/re-add my printer to Connect (and lose history/stats) unless I really have to.

Opened on issue on Github as well:

Hi, thanks for the bug report. It turned out our compatibility table has grown a bit too complex :)). This particular case along with some others should be fixed now, sorry about that!

I have the same issue on a MK3S with MMU3

RE: Cannot send Mk4-MMU3 file stored in Connect Files to MK4 with MMU3

Same issue today with a MK3.5 + MMU3 an FW6.0.2. Have to use in PS2.8 A5 a physical printer, because the "Send to connect" button does not find a compatible printer.

RE:

PrusaConnect is now completly unusable for me!

I have 2 MK3S+ with MMU3. When trying to print using PrusaConnect i get this message saying i have no compatible printer.

Hi Ed, is the issue still persisting? From the screenshot you provided the printer is not marked as with MMU, otherwise the printer icon would have the MMU unit shown. Have you turned on the MMU option in the Printer Settings?

RE: Cannot send Mk4-MMU3 file stored in Connect Files to MK4 with MMU3

I have set the MMU3 on in the printer settings. I didn't have any isseus before the last PrusaConnect update.

I removed 1 off my printers from Prusa connect. Now i can print my mmu3 files. If i add the 2nd printer again and i try to print a mmu3 file i get a selection screen for my printers. Both are now marked as incompatable.
