Hi m8

No I do everything in metric, but find it's odd because the first two programs I did work fine, but anything new doesn't seem to work right. I re-did the vac bed program, but now find the bit drops to the cutting height; still a good 20mm above the work piece then runs across to where it needs to start, and had it been cutting would have gone straight across the workface, instead of travelling then dropping down.

I'm going to uninstall the program and start again, as still no joy from the artcam fourm.
