Can I mix DMM and Teknic SDSK step and direction servos on the Acorn. (X and Y DMM and Z Teknic)

Acorn doesn't care where it sends its step and direction signals.
Cheers,

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

As Tom mentioned, not an issue.
Do make sure your motors are sized properly to the driven load.
Not sure which DMM drives you are talking about, DYN2? Which require DC input?

You have to pay close attention to the FAULT signal. Teknic pulls that signal LOW until there is a fault, then the signal goes HIGH. DMM leaves that signal HIGH until there is a fault and then pulls the signal LOW.

Excellent point Mike.

Thanks to everyone for your help. I was considering using a Teknic NEMA 34 on the quill of my knee mill for Z. I love the simplicity of the SDSK system. I use two of them on my lathe. However, after doing a price comparison I have decided to use a DMM NEMA 34/DYN4 motor. I already have three 130mm/DYN4 motors for X, Y and W (knee).
