And this is not possible? N270 G0 Z#33 + 2

It looks like it works if you remove the N300 line numbering before the while

It looks like it works if you remove the N300 line numbering before the while

it works, but it not shows all the paths on the Toolpathview.
And it's possible to do G0 Z#33 + 2 ?

I will have to verify the toolpath, can do it in a few days only.
No, you can't do G0 Z#33 + 2
You could do:
#33 = #33 + 2
G0 Z#33

A working facemill gcode with lateral and Z steps.(test the toolpathview)
