Terry,

OK, I'll give it a try....

Well......  Got a new one today!  A short program, just 30 lines or so, peck drilling two holes.  If I set look-ahead to 1, it works perfectly.  If I set it to 20, it will, at some random point in the program, try to send the Z axis to the other side of the planet at warp speed!  Some problems with offsets (even though this program isn't using any....).  Brian is working on it.

Regards,
Ray L.

HIYA RAY you will also find that Mach will sometimes MOVE the Z at an accelleraton rate so fast it will Trip a 1kw servo on a positionaol error(NO it is NOT a servo problem).
