Author Topic: MACH3 software DRO vs actual position issue please help!!!!!!!!!  (Read 251 times)

Hello, I am a newbie at lathes, I've spent most of my short experience time on CNC Mills, I just purchased an American Bridgemill and I'm having some difficulties. I'm going to explain this the best I can. I did make a previous post but I don't think I explained it correctly.

Long story short, I'm trying to cut a diameter using the jog. My numbers on the MACH 3 DRO do not match the actual diameter of the part that I just turned. All settings are on Diameter mode. If I cut .02 of a .5 diameter the DRO shows me .480 while the part diameter measures .460. Is there any way to see the true number on the DRO. i.e. if I cut .02 radius the DRO shows a .04 Diameter change?

I figure this is a setting someplace in the Mach3 program how do I change this?

Thank You.

Config -> Ports&Pins -> Turn Options -> X-Mode may help?
