Hi, I have just built a cnc and to all extents and purposes it works. But, there is always a but I have been trying to put together some code to level the spoil board, it starts well but after it prints about a third of the way through it stops, normally I would assume a problem with the build but other code works no problem. I am using BCNC via grbl and Raspberry PI. hope someone can assist with this. Thanks Ernie
