Help wiring G0704 Spindle to Mesa 7i96s

I have not. I've been taking too long figuring out if I can make a dual loop feedback system and learning I should pause that endeavor for now. Currently working on seeing if this thing can cut a semblance of a part then hopefully spindle control. Will update if I learn anything.

I did finally get my spindle to work. I removed everthing from the spindle control cabinet and replaced them with a KBSI-240D signal isolator paired w/ a KBMM-125 DC drive. Relatively simple wiring, I can put together a simple diagram if needed. Now I'm working on trying to get RPM feedback from the existing tach.
