Powering 7i76e board was created by Aldenflorio
I have several questions, am I able to use either a 12v or 48v power supply? Along with that I find it quite confusing with the diagrams of how to wire up the THCAD-10 to the Mesa, along with that the wiring to the hypertherm 45 (not the xp one)

THCAD FO+, FO-, GND, +5V
7i76e A+, A-, GND, +5V

The output of the power supply only has -v and +v

so do they go in the perspective a’s?

what do I hook ground to? And what do I hook +5v to?

I would buy a 24 volt power supply for plasma. This video I did covers all the connections

Maybe I should know this: though the output of the 12v power supply is -v and +v.

does -v go to +24v and +v go to ground?

-V to GND
+V to +24V
You should really find someone who knows at least a bit of electronics.

Yeah, I’ve built an entire working table from scratch already. This is my second. I just forget stupid stuff like this sometime
