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.
