New Project with Mesa 7I96 and THCAD-05

I would do it that way with the automation interface. I think without, I would send 5 volts back to the machine on 2 wires and have the frequency output on another two as it might be safer.

Yeah, I mounted mine in the plasma machine, I don't want any chance of the full arc voltage coming into the panel. I sent 24VDC to the machine and used one of those cheap buck converters to trim it to 5V.

How much easier would it be if I just bought the interface card for my machine? Would I need resistors and would I need to put the thcad in the plasma machine still?

You wouldn't need resistors and you could mount it in your control panel.

Thats a better idea. Solves any voltage loss. I used one for my laser pointer.

Need help with the motors stuttering on the axis on the wizard they run fine but when I run them through the axis they tend to stutter a bit I see it on the velocity on the display where they drop in speed and pickup and drop a bit. I have them wired on my kitchen table for now to make sure all is good before proceeding with the build. I mess with current settings on the drivers and still the same and this happens on all motors I see the stutter. Any idea what it can be?
