MMU2 Firmware IS titled "MMU3"
You all know that the firmware located at:
https://www.prusa3d.com/downloads/firmware/prusa3d_fw_3_13_3_MK3S_3_0_2_MMU2S.zip (Link from MMU2 firmware download)
After decompressing zip files the firmware within the zipped folder is:
"MMU3_FW3.0.2+878.hex"
(The occurrence below happens after an update takes place on the MK3S - firmware 3.14.0) -
After double checking that I had the correct download for the MMU2- I Updated the MMU2 firmware... Now - every time I print - I get an error message that states - The print is sliced using a different printer - which is not the case...
I also got an error message about an "unknown Problem with the Z self leveling measurement" on measurement 3... The machine just started automatically doing its own full Z calibration ...
NOTE: Its already a huge hassle keeping up with your naming conventions... (ie adding a number and "plus")... or (2.5)... These are not industry standards for how to name hardware after modifications, so It's no wonder people developing the firmware updates can't keep track either... A BMW 3 series also has a chassis code (ie F30)... This helps identify that Yes - Its a 3 series, but this unit uses parts for an F30... This is an excellent example how to identify hardware when making revisions... We should also adapt this... Thank You, The End...

I also encountered the same problem as you hope it will be resolved.

I reinstalled the software for Win, but still need new parameters after identifying the new update.

Any update to this? I literally just updated firmware for my MK3S+ and MMU2 (they were very very out of date) and now everything I print complains that it's for the wrong printer. Seems to be behaving normal other than that warning at least.
RE: MMU2 Firmware IS titled "MMU3"
Looks like a firmware bug, and also looks like Prusa isn't interested in fixing this because I have the same issue after flashing my MK3S and MMU2S with the last printer and MMU firmware update (with MK3S_MK3S+_FW_3.14.1_MULTILANG.hex and respective MMU2S_MMU3_FW3.0.3+896.hex).
I tried and doublechecked everything on the slicer side and my printer keeps displaying the same error message "model was sliced for another printer model" every time I try to print a model (sliced correctly using PrusaSlicer 2.9.0).
I verified the generated gcodes in subject and they contain the correct printer model check: "M862.3 P "MK3SMMU2S"
So, the only logical issue remaining is that the printer is now looking to find a different string when it runs the printer model check in the gcode.
So, we all have the same issue here, an issue that came up with the 3.14.0 fw version and Prusa hasn't still fix in the 3.14.1.
Finally, the questions we all have are:
1. What is the updated printer firmware looking for to find in the gcode when it does the printer model check?
2. How do we properly fix this issue? (hopefully without removing the printer model check from the original printer start gcode, which has its good purpose for a reason)
3. Does Prusa have any plans to fix this bug?
