Re: Analog Out weirdness, please help

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: https://www.amazon.com/Isolator-Insulation-Reliability-Conditioner-Transmitters/dp/B09TJTCDQ8 This product did not work. It requires 24V input,...

Re: Z/W Axis summing with scale on Z axis

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.

Re: Kitamura Mycenter Zero - DELTA Ethercat Retrofit

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.

Re: Help on isolation switch fit two circuits/power supplies

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...
