I just got Mach3 licensed got my ports configured and the motors tuned. All axes responds well to manual control. But when I try to run the roadrunner file recommended as a test in the videos I run into a problem. The program seems to run to completion but it routes out the entire design in an area about 20mm sq. I can’t image that this is the plan. So I must have something misconfigured in Mach3. The manual says I can scale a part but I don’t see where it tells me how. I would appreciate any suggestions
