Mach3 & V-Carve Problem

[Ricardoco]

You have G21 at the beginning of the G-code, which defines it as metric and it certainly looks like it's in metric so that's fine. Perhaps Mach3 has inadvertently changed to imperial, as that can scale everything by 25.4 (or 1/25.4) which would make the effect you describe.

How mad is that, i didnt even check that because its a fresh install on a new pc and i know i selected MM, then in manual mode it worked fine, however, not with a program loaded with a g-code instruction stating metric!!. well it looks like you were correct, because when i checked it was set to Metric.... so go figure???
