@zapta Alright.. using your comments as a place to start I found that having my Jerk control turned on in Cura led to some M566 x1800 commands that it was picking up. I turned off Curas control and just set it in the machine settings and now it slices properly.

I have installed this into Cura 4.62 and using on my Railcore II. When it goes to run it always defines my X end point as being 1800.

M557 X103.850:1800.000 Y115.304:164.705 S10.000 ; Leveling mesh defined by LevelingMeshOptimizer

Railcore of course doesn't like this and then just skips the mesh:

Error: M557: bad grid definition: Too many grid points; suggest increase spacing to 44.2mm
Error: G29: No valid grid defined for bed probing

Is there something I am doing wrong?
