Looks like your drawing in ArtCAM may be too big, either that or you need to do some scaling. Afraid I am not familiar with  ArtCAM so cant really advise

If the G00 Y-40 is the first move in the G-code, then it sounds like your part is set up in ArtCam 40 units on the Y axis from zero origin.  If that's the case, when you zero the DRO's in Mach and run the part, then the first move would be a rapid move to where the part is oriented in ArtCam.

you are using the wrong post processor if that's the first line of code output.
Which post are you selecting in ArtCam
