Thanks all. It's has the smooth stepper. I'll see if I can find a better dedicated PC but would rather spend the money on a rotary table.
Going to print the manuals next week at work. Picking up an old steel desk off CL today to sit it all on.

So far have a Taig CNC mill with the Ethernet link. Installed FreeCad on my laptop I use in the house. Can Mach 3 go on the laptop or should I dust off an old Dell and put it next to the mill downstairs?
Everything on the same wired network.
Thought could use the old monitor with the Dell...
