MK3s With MMU3 not showing up as an option when uploading from PrusaSlicer
I recently upgraded my old MMU2 to the MMU3 when I finished installing it back on to the MK3s Prusa Connect did not recognize that it had the MMU3 and I was unable to send files to the printer. I removed the printer from Prusa Connect and added it back in and this fixed it for 2 prints. Now when I try to send any files to the printer Prusa Connect will not present me with any printers and just says theres no compatible printers for the multi material files.
Things I have tried so far:
Reseting the printer and MMU3
Disconnecting it from the network and adding it back in once the printer and MMU3 are booted up
I am currently running the latest firmware on both the printer and the MMU3
Thanks for any assistance with this.

I have this problem with my XL as well. I recently updated the FW to 6.2.2+8853. I did a print of a couple prusa parts, then Prusa Connect doesn't recognize the printer as online. I added the printer to prusa connect, then I could see that it's idle from prusa slicer's prusa connect, but when I slice and try to send to connect it says there are no compatible printers.
Looks like I can manually transfer the gcode file to USB like a caveman still, and start a print.

I have this same issue. I see the no compatible printers when trying to print anything. Upgraded to the MMU3 on my MK3S+. I can "force" it by uploading the file directly and printing but not ideal. Hoping there is a way to resolve this.

It is the same for me. Seems like the printer is sometimes not recognized as MK3SMMU3 but as MK3S.
I can sometimes fix it by rebooting the RPi and the printer, but it is not fully reproducable. Sometimes waiting helps.
tbh this is quite a nuisance, as it completely breaks the Send to Connect workflow :'(
I'd be more than happy to swap the auto-recognition for a configuration setting. I imagine most people don't detach/attach the MMU that often.

Hi all, same for me, I have 2 printers MK3S+MMU2S and prusa connect call them only MK3S and stop me from uploading or printing gcode files
It says "No compatible printers"
I use RPi zero attached to printer board
I formatted 2 new microSD cards and configured the 2 printers again, removed and added again to connect but nothing changed.
I must upload directly to the printer from the connect page and functionalitys in the android app are limidet

I applied this fix a few weeks ago and have not had an issue since. If you feel comfortable with ssh - it was pretty simple to update the file manually.
