Describe the bug

Since I upgraded SW to 3.14.0 via file E3D_REVO_FW_MK3_MK3S_MK3S+_FW_3.14.0.zip MK3S_MK3S+-E3DREVO_FW_3.14.0_MULTILANG.hex printer claim on each g-code that it is sliced for different printer type.
(I've uploaded this firmware multiple times to ensure that I didn't mix anything)

I used previous releases of PrusaFirmware made for E3DRevo hotend modification and always all worked well

In PrusaSlicer I use Original Prusa i3 MK3S & MK3S+ MMU2S Single profile.

Here is example G-code (using 0.6 nozzle, but there is the same with other nozzle sizes)

lock_cover_thin_0.6n_0.35mm_PETG_MK3SMMU2S_3h2m.zip

How to reproduce

1. Upgrade pinter with E3DRevo extruder to 3.14.0
2. Slice g-code as before
3. upload g-code to printer
4. Start print
5. "G-code sliced for different printer" warning appear on printer LCD

Expected behavior

Printer should accept his g-code without warning

@NightSkySK Thanks for the report. Are you using a custom PrusaSlicer Profile?
In the provided GCode you can see these two M862.x Gcodes

;TYPE:Custom
M862.3 P "MK3SMMU2S" ; printer model check
M862.1 P0.6 ; nozzle diameter check

which tell the printer for which printer type and nozzle size the Gcode has been sliced for.
The M862.3 P "MK3SMMU2S" ; printer model check points out that it is sliced for a MK3S with and MMU2S.
As the printer can't detect which hardware version of the MMU is connected it will set the type to MK3SMMU3 and that doesn't matches the provided version.

Please use the newer PrusaSlicer MK3S + MMU3 profile and / or update your custom PrusaSlicer profile.
If you don't have the MK3S+MMU3 profile use the Wizard to add it.
In case you have a custom profile for your REVO, you can use the Compare presets with another in PrusaSlicer to make a new MK3S+MMU3 profile from your custom MK3S+MMU2S profile.
