Hi all I'm new here and could do with a little help
I recently purchased a small milling machine equipped with mach 3
I've been using the machine manually with no problems, however today I imported a dxf file from autocad, loaded the g code and when I run the program I have found
that the actual movement of the machine is greater than the movement shown on the DRO.
Mach 3 is not something i'm used to, could this be a simple problem or something more serious, any help would be greatly appreciated.

Sounds like the steps per unit are set incorrectly, either that or you have scaling set.

Thanks for this I have changed the steps per unit and it seems to be ok now
