Hallo
So habe ein Foto gemacht von den Zeilen wie ich das reingeschrieben habe und von der Fehlermeldung. Vielleicht findet wer den Fehler.

This is really a big big question. I've noticed most of the commercial 4th axes are worm gears driven by servos in the 30:1 to 100:1 range. That said, I've read good things about harmonic drives driven by servos or steppers. The biggest concern I had when deciding on my 4th axis was backlash. Harmonic drives and commercially built worm drives are really low backlash. I've always favored servos for their built in feedback, but steppers can also run encoders. I've never been a fan of open-loop axes of any sort.
