Hi everyone, I just started having a new problem: as my progam is run, I notticed that the cutter cuts deeper and deeper. Attaching a dial indicator and then jogging the z-axis up and then down 0.125" inches results in the head moving further and further down (between 5 ten-thousands and a mill each time). I tried changing the acceleration on the motor from 7.5 in/s^2 to 1in/s^2 and then 10 in/s^2 but it didn't seem to make a difference. Any advice what to check? I have a Taig Micromill 2000 being run by Mach 3. Thanks,

John
