Update: This issue has been (sort of) resolved. turns out that the display requires an extruder axis to be defined to consider the printer connected. had to add a fake extruder axis on unused pins that normally connects to the M5 expansion board. The screen works as expected but the controller is of course spitting out errors on boot because there is no driver connected to it’s specified pins.
If anyone actually reads this i hope it may help you out.
The core of this issue lies somewhere in the code that determines if a printer is connected but unfortunately i was unable to find said code to be able to modify it. Any pointers in the right direction would be awesome.
