Hi,
I have been trying for several weeks to set up the auto-zero function in Mach 3. I have tried several scripts, which I am sure work ok (from the amount of positive comments)
My spindle is earthed, so I only use 1 cable to the touch-plate. On the diagnostics screen the digitize light lights up when the plate touches the bit. But, when I run the script, the spindle actually moves up.
I have changed my screenset and put an indicator light beside the auto-zero button. I have noticed that this light flickers very briefly for no apparent reason. Does this mean that I have a short somewhere?
Electronics is not my strongest suit, so I would appreciate any help you can give me.

Thanks,
Gareth
