3d-XYZ Z ACME Lead Nut Block and Z Axis

Hey all,

Is it normal that the Z Acme Lead Nut block runs really hard over the Z axis?

This should normally go easy, no?

Mine is really hard spinning over it. Is this normal?

Kind regards


Ok, after moving it hard by hand 3 times up and 3 times down it is moving slightly. I assume it was just a bit tight :wink:

I had similar, after loosening off the nuts that hold the z-axis in place slightly and loosening and re-tightening the bottom plate to allow it to seat itself rather than force it to align with the rail it now moves with relative ease.
