Rich
Im on vacation and not near the Mach3 PC. I have attached the manual and the wiring diagram. Google drive is with you every where. There was also a MACH3 copy with the card but I did not use it. I have a legal copy. The seller claimed it was a Smooth Stepper card. Im quite sure that the card does not handle treading and this is the problem.
What if I connect the index sensor direct to the LPT? Its possible to have several cards in the Mach3.
Thank you for the advices Rich.

Yea, right, and he also has a bridge in China he would like to sell you! Evil

As replied before,  Can't specifically answer if that will work.
You can try and see what happens.....................

So ask the seller these questions:
  Does the driver board support Mach3 threading?
Did he say yes?

In threading you can't have two different inputs for the RPM as indicated by the DRO.
The index provides rpm info to Mach, and as you said, the index and DRO indication seems to be working. So manualy set the rpm for the spindle, then Mach3 should be using the info from the index input for threading, and that will be reflected in the DRO.

When time to implement threading, the rpm value is given to Mach, it must be stable before it will be used ( else motion will not occur). With two inputs they would be fighting each other where one implies  speed up whle the other may slow down, and that fighting also impacts the next threading  move.

This goes back to:

   What exactly is represented by that output from the card?
BTW, I requested the xml file you are using for the lathe.
I am not a mind reader on how you have things configured ........... Smiley
