I have a running problem with art cam

I use vetric for my 2d cutting with mach 3 and punch for my drawing these all work well with no problems

However when I try to run a 3d program from artcam it will no run, the scale is all wrong (micro mm it would seem) lol

has anyone got any answers or had the same problems I've owned Artcam since 2015 but never used it shame as it's got some nice features.
