I have decided to have a go at Linuxcnc/PathPilot and wanted to sort out my schematic before completing the wiring so no surprises get me after the fact. I wanted to defer to the trailblazer who have been there and done it to make sure my foundation for wiring is sound. From the other thread, an update, I purchased a correct 5v encoder to avoid the voltage divider requirement, rather start going into this with as few "work arounds" as possible.
If you can spare a moment to review my connections and poke holes in it I your input and feedback is greatly appreciated!
2 things, Mesa has diferential outputs for step and direction, so that is +-10V, not 5V, some drives (most) are 3.3 or 5V only so you have to use only dir+ and step+ OR dir- and step- and wire the other wire to gnd or +5V respectively. Or just make sure they can handle 10V.
Also i would not power the switches through the Mesa board, wire them to power supply through a fuse.
The rest is good.

This is the information I found for my motors and drives, I'm not sure if they are ok to run +/-10v. Maybe you see something I don't?
The information I posted I see says differential, and 5v or 24v, but I don't see anywhere that it states +/- 10v. Sorry if this should be simple, but I've always wired it the other way. But I see it states that differential is better in the manual and if these drives can be wired that way I would like to do so.
Ok after a long time searching, i found this blurb in the description... And it states that all step and direction outputs are 5v....... And my drive state they support differential so I'm going to assume I am good to go to write the step drives as shown. I wil correct the sensor voltage connections direct to the 24v power supply as instructed!
Well, after a long weekend of wiring, the control cabinet is finished. Just need to run a new 220v power outlet to the new lathe location and power everything up. Now it's time to dig into Linux cnc and figure out what's needed to make stuff move!
