In CamBam (free version) the tool path looks correct, with multiple depth increments and multiple passes of the profile. When I load the gcode into M3 (free version) it only "loads" the top profile pass. It does not seem to recognize the additional passes & depth cuts. It will run one pass of the profile and then quit. I expect it to increase the depth of the bit, then run the profile again.
What am I doing wrong? Is this a limitation to the free version of M3?
Thanks!
