Post your xml file.

BTW, I can't speak for WIN-CNC and will not entertain a comparison nor adaptation of Mach to their
boards / whatever.

It may not be a mechanical issue as the only thing at this point is that the gcode pathing is not the problem.

Here is simple test as far as postioning.
Air cut the program to and including line N180. ( so get rid of the second pass). The DRO will be at
X &Y coordinates of N180 and the location of the head should be that distance from XY=0.
If it is not there then your steps per unit may be wrong, or, it can be attributed to nunmber of things.

Measure accurately and also consider spindle runout.

Hi Rich

I finally found the problem.
As you said first it was a Hardware issue. It was a coincidence that it worked with the other Application.
The problem sesms to be the computer hardware. I've tried another machine and now it works.

TTL Signals were incorrect so the step motor lost steps during movement.

I'm really sorry for the work I've generated.

Best Regards
Chris

Chris,
 As long as you got it working that's all that matters. :)
