Looks like he bypassed the velocity loop and soldered signal wire directly into a specific point in the amplifier farther down the line. This is working well, no issues with motors or drives so far.
When i got the machine I cleaned up alot of the wiring and traced nearly every wire in the machine and got rid of anything not needed. Nothing at all worked in the original control box on the front of the machine so i stripped that and added a LCD display, keyboard, buttons and overrides and an MPG so this machine could be operated like a normal VMC instead of fiddling with a laptop. I had to add a Konnect board to get the number of inputs and outputs i needed.
