I originally planned that on my Bridgeport conversion but after using my CNC-only Shizuoka for a while (it never had any handwheels), I decided that for me there's no point retaining manual controls when you have a wireless MPG. This achieves the same effect (handwheel controlling quill and table movement) yet can be used almost anywhere. You also get consistent and deadly accurate operation with DRO readout and the moment of inertia of the X&Y handwheels wasn't improving the servo responses on my system. I often do manual operations using the MPG such as squaring up stock, slotting, drilling holes etc.

I'm starting to have similar thoughts about my lathe conversion, having started out planning to retain all manual controls. Instead I think I'll keep the manual parts in case I sell the machine and go fully CNC.
