Found the issue.
First the warning "phase A may be disconnected" which i was thinking its the motors is caused by not connecting the Z Motor. I only had X and Y connected for testing and saw the homescripts lift Z.
The main issue actually was the endstop switches. I have microswitches which are most likely worn or the cables are broke but they when i just wiggle the table they trigger like 10 times.
After replacing them all runs fine 🙂 The motor noise i thought was part of the problem is actually the normal idle sound i tweaked with M569 F. I was used to stealthChop from my old 2130 haha
Thanks for the help!
