The glass scales will give you the table position so it might be best to monitor them.

I'm installing rotary encoders on my servo's which will provide the feedback to the Gecko's, pretty straight forward. The machine also has glass scales installed that I plan to retain so that I can use the DRO when using the machine manually. Originally I thought I had to use a sound logic encoder board from Rogers Machine (which I have purchased but not received yet) to accomplish this. However, after reading the Mach 3 manual again, can't I just connect the glass scales to the differential inputs on the SS to do the same thing? Or does the Encoder board come with some additional software?There are only 3 differential inputs on the SS but you could connect to them or for that matter any of the other Inputs but just single ended.The encoder interface board comes with a Plugin I believe which allows you to set up a following error to halt Mach if its exceeded then you can update the DROs from the encoders and carry on.
Another question about the Sound Logic encoder board, does it just plug into one of the 26 pin headers on the SS board? Or does it have to go back to the PC to a parallel port?It was originally meant to connect to a second parallel port so yes it just connects to Port2 on the SS.
As far as inputs/outputs go for Mach 3, can I just choose whichever Port/Pin I need as long as I choose one that is assigned to an input or output as necessary?Yes just the same as you would have done if using the Parallel Port
