Problem after firmware update
I just updated the firmware on my MK3S+ and MMU2S to the latest version and now I'm having issues with the MMU2S. I get an error when I try to print stating the idler can home properly and it cites the code prusa: 04125. It tells me to look for obstructions that would keep it from completing its task. FWIW, it all worked fine before the update. Also, I found after the update that I had to go into the settings and turn on the MMU, which seemed odd.
Any help with this would be greatly appreciated.
Thanks

RE: Problem after firmware update
Completed firmware updates 3_13_2_7080 and 3_0_1 on Mk3S+ with MMU2S. Printer updated fine, but MMU2 behaved unusual at startup, and printer was in non-MMU mode. Turned MMU on in settings (thank you Bill) and MMU repeated issue, but advised startup issue with spool and gave me options! Reduced sensitivity from 7 to 5. Now MMU starts up super fast and quiet. Not sure if sensitivity is too low, but can't get back to this setting to test! Oh well.

RE: Problem after firmware update
I backdated to 3.12.2 and 1.0.6 for the MMU2s and everything works again. After the latest update to PrusaSlicer to 2.7.1, I'm getting a notification of a firmware update available, But I'm not trying again until after I upgrade the printer to an MK4. I don't need any more trouble with it.

RE: Problem after firmware update
thanks i changed to 3.12.2 and 1.0.6
hopefully this avoids whatever hell prusa caused. but now i have no project to test with it as i could not use the machine and went with an alternative.

RE: Problem after firmware update
Since the MMU was disabled after the update, make sure to re-enable it in the settings. This might have impacted the configuration stored in firmware, and re-enabling it can help reinitialize the device.
Go to Settings > Hardware > MMU on the printer’s menu, and confirm the MMU2S is enabled.
