My material is .04" (1mm) metal. My file is a 2-D DXF file. My intent is to just cut out a shape. Within in Meshcam, I am selecting “cutout” only. When cutting out the shape, the bit does not cut into the metal, it just runs along the top when using a z thickness of 1mm. I have set the thickness of the material to 2mm which allowed the bit to cut into the material, and am working up through .5mm increments. It finally cut through when I sent a material thickness of 3mm
For the bit, I have the depth per pass at .01", however, each of my runs makes just a single pass.
