I both my CNC about 6 months ago. Got frustrated during calibration and set it aside.
I am now back at it, and am cutting the sled. I am running into to a small issue with the sled cut though.
I am using 7/16 OSB as a first time trial (its what I had lying around). I find the Z axis ends up going too deep and cuts into the background board of the frame. I think this is referred to as the waste board. Since I am thinking my OSB is too thin, how would I go about knowing how to adjust the Z axis to avoid the over cut? Where in the Gcode would I find the thickness of the board that the code was written for?
