1 or 2 dedicated 120VAC circuits for my CNC?

YES! Thanks. I had a feeling I needed to run power through the output terminals on the SSR instead of how I had it hooked up. I just was not sure where the power should come from.

So just to be clear, I should run the power for the contactor from the 24VDC PSU directly and not from field power/ground on the Mesa?

Nevermind! I got it! Thanks for the guidance. My brain is mush.

Not sure why the red light on the SSR when it is enabled. I normally expect green for go and red for no-go. LOL. But whatever. It works.
