I have a custom Cartesian style 3D printer. The controller board has been upgraded to a BIGTREETECH SKR V 1.4 Turbo. This is a 32 bit board.
Marlin 2.0.3 seemed to build and install with less issues than others. I'm using VS code to work with Marlin. My big problem is with homing all axis. For some reason the Z axis finishes with the extruder 6 mm above the bed. The extruder goes below the bed to start printing. It's damaging the bed. What can be done in Marlin 2.0.3 to fix it?
