Title: Now What! Jog says mm - Gcode say G21 - machine moving in inches
Post by: kdoney on August 12, 2009, 08:13:56 AM

I do appreciate your help and I know this is the best value I have found in many years of hobby (or professional) cnc.

Presuming you have this working now as your other thread seems to say you are threading correctly.
Had a look at the xml and it seemed fine and seemed to work fine here.

No, actually this is a boring move. I just found out I've been using an unlicensed copy in the shop. Would that matter? I can check again.

I did notice you had the Y axis enabled in Turn, most people dont have a Y on their lathe so if you dont disable it. Probably not the problem but worth doing anyway.
