btw. those {1} are not actualy in the code might be a Bug with this Forum.

It dosen't want to move Z even.

M574 X3 Y3 S3

X3 Y3 is not valid. It must be either 1 or 2. 1 is low end of travel, 2 is high end of travel. S3 is correct though for stall detection.

The Z moves are the only place where H2 is correct. H1 means seek the endstop. H2 means move the motor regardless if it's homed or not.

I tryed this for now with no moving Axis.

Should probably remove the H2 from that one.

Meaning nothing moved?

[AS-3D Druck]

Okay i got it now kind off.
My Problem was i got in my config before (2.05) steps M92 and after that M350 for interpolation on those steps etc. but in this config as you can see before i got it the other way around.
So i changed that and now i got movment back.

The only thing that i try to fix is now why it runs to the set direction is on the End and still tackles it a few times and than sets back to the middle as intended.

I currently try to change the sensitivity but still not great.

//EDITE:
Got it now on 4 and it seems to work

I'm not sure what that means.

But sounds like you got it working now?

Yes, i can provide my new Home X and Y File + Config if someone wants to look at it. (Troubleshooting etc.)
