Ok, I didn't really know where to put this one, so I picked a forum that has alot of viewers. I am in the process of converting an old manual lathe to CNC. I was thinking that I could drop the gearbox off of the front , and just move the 2 axis with the jog pendant, but what if i still would like to use it manually sometime. Here is my solution: buy 2 MPG wheels and mount them on the front of the carrage so that I can still get the feel of a manual machine. Here is my problem: this is my first CNC conversion that I have really done all by myself. I'm running mach 3 through gecko 320's into 1200inlb servos with amt102 encoders. Where exactilly should the MPG wheels wire in to make this thing manual when I want it?
