Well, some progress was made but not everything is working.
- I cannot extrude. Everything is up and running, it seems, but the stepper motor of the extruder won't turn. I also see upon start-up that Marlin echoes to Pronterface: "Filament settings: Disabled". But I don't know where to enable them.
- Another problem is that the communication with the TMC2130s is not stable. I start the printer (and check with M122 that all enables are false) and run G28. This works sometimes, sometimes it doesn't. X and Y homing works, sometimes Z does as well. If Z homing fails, it is due to the Z and E enables coming back true, when M122. If it didn't fail here, then I ask G29 and during this operation it fails. M122 shows some enables have changed to true and everything stops. Resetting the printer works. I am now putting on a 1,5A step-down converter instead of the lonely LM7805 I soldered to the back of the Arduino Mega, hoping this will give a better / more stable 5V. Although the LM7805 should give 1,5A, too, and it is not really warm, I just hope this will fix something...
