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...
