What Post Procesor are you currently using??
Attached is the latest Mazatrol M2 PP, it is configured to use an "A" axis rotary 4th axis.
BobCAD-CAM does not have a built in DNC for uploading or drip feeding to the Mazatrol control, you would need either the Predator Level 2 that you may have depending on the version of BobCAD you have, or another sofware like "Easy DNC" for example.
Hope this helps
Regards
Rob
