What happened? 

The printer can detect if a loaded G-code is not compatible with the current printer setup, thanks to a set of saved hardware settings. In this scenario, the printer shows the message "The G-code isn't fully compatible".

Error name: The G-code isn't fully compatible

Error code: #31803 (CORE One) #35803 (CORE One L) #26803 (MK4S) #27803 (MK3.9S) #28803 (MK3.5S) #13803 (MK4) #21803 (MK3.9) #23803 (MK3.5) #17803 (XL) #12803 (MINI)

How to fix it? 

Ensure full compatibility between the G-code and the printer. In particular, double-check both the G-code and the printer hardware settings in LCD Menu -> Settings -> Hardware, for differences in the printer model, the parameters of the installed nozzle, and other hardware settings.

I encountered this error it was honestly just that I forgot to change the printer nozzle size in settings. Glad it slowed me down to figure out something was wrong but I think just telling me that the nozzle settings are wrong similar to filament warnings would have been more precise.

If you got your printer set-up on Prusa Connect, then go to the tab "Prusa Connect" and select the printer, and push the button "Set as current".

I gotta say first time Prusa owner, Core One +, just finshed the build and this is very very annoying to have to fight every single print give the same error. Does not care if its PLA-CF, PLA, ABS, or PETG same message even if I select the correct filament from the printer and presets in PrusaSlicer. It takes loading and unloading to get it to just print. Not a good look.

First off, you if ran into this after recently upgrading your firmware you can safely press Print to continue.
To fix the problem, when using the Prusa Slicer, with an up to date version of the Slicer, go to the printers tab and printers are available, for me they are;
Original Prusa MK4 0.4 nozzle
Original Prusa MK4 Input Shaper 0.4 nozzle
Select the Input Shaper version and this should correct the issue.

Note: The only difference I can find are in the Printer tab Notes section.
PRINTER_VENDOR_PRUSA3D
PRINTER_MODEL_MK4
has been replaced with
PRINTER_MODEL_MK4IS
