Well, that was a boring afternoon. The issue of the extruder is fixed, I fitted a different stepperdriver and now it works. I also think I know the enable issue is not an issue. Marlin keeps enable at false, until you call for the axis (or extruder) to move for the first time. Then enable becomes true and it all works.
The issue now comes down to the homing failing. I made a little gcode printfile and ran it from SD, as I feel the computer communication also burdens the MEGA's processor. The hotend heats up, Z moves, X and Y are homed, and then the Z should start homing but it doesn't. It comes back with "Homing failed" and I need to reset.
I also tried homing all axis individually, moving 10 mm away from each sensor before homing the next axle, but it keeps failing on the Z.
All thoughts are welcome, I will now change the topic title if I still can.
