i just got a series 2 ez trak DX II. 1996 vintage. after i have loaded a program and click until it says turn spindle on to enable run, and i go to hit the / button to zero the z axis after i have touched off, the program locks and the upper right hand corner goes to AUTO RDY, and i cannot proceed with the program. sounds like a software glitch, but i was wondering if anyone had ever heard of this, as it is annoying to not be able to zero my z axis anywhere in the program without locking it. please help me...
