Question about shielding of cables

[JAZZCNC]

Thanks for the response. I will be using the UCBB breakout board paired with the UC300ETH. I bought them in a package from CNCDrive in the hopes that it would make compatibility easier. Does that change anything with your answer?

The UCBB is a good board with nice fast opto's and you won't have any troubles with it.

I did miss understand the 24V PSU and thought you were using the control PC to provide. So Ignore what I said, how you have it will be fine. But I would still use Shielded cable and do all that I said regards Star Gnd etc.
