Found a post about setting the IJ mode from inc to abs. That seemed to fix it. I did a dry run on my good PC and all looks good. The only thing I need to figure out now is the Z movement. By default it sets the cut depth to 0.000. Is that the standard? All of my other test runs I set the material surface to 0.000 and the minimum to however deep I want the cut. In the case of this drawing it is -0.090. Or is it better to keep the minimum set to 0.000 and the maximum set to about .250 above the material surface?
