You CAN use the Z-axis scale for feedback. You just need the Mill Ultimate software. You will get duplicate encoder messages when you exit machine setup, but you can ignore those.

After all best practices have been employed (twisted pair shielded wire, proper grounds, bypass caps, etc.), you might want to look into a signal isolator:

Actually, they can transmit significantly more Hp for the same mass. I've added idlers in the middle of my long belt span on my lathe to control whip. Same principle as a tensioner.

When I changed from a double-v to J-section belt the noise was CONSIDERABLY less.

This is the cable that I use - "Servomotor Continuous-Flex Cable" It's gone up a little - 14Ga is now $7/ft, and 10Ga is up to $12.45/ft but still worth it.

I have 4 machines with VFDs in the control box. Two are Yaskawa, one is a Baldor, and one is ABB. As Gary says, the amount of noise radiated from the VFD is very low on name brands. And, I'm using $6/ft shielded inverter cable, properly grounded, for the motor connections. You don't have to house th...

Most people just resort to adding a relay.

Gary has already stated the proper technique. You want a SINGLE power entry point to your machine. This is directly attached to the main disconnect. It is then divided to a series of breakers/fuses sized for the different loads. The wiring is sized to carry the amperage of the last upstream fuse. Fu...
