Part 4 of a series on how to build a CNC plasma cutter table. All the parts are complete. Check out my playlist for the build below. In this video, I am wiring the electronics of the CNC table. Some back story this is my 3rd build of a CNC plasma table. The first build you see in this video, while the second one I made was for a friend, featured in the THC video on my channel. This design is based on the design I designed for my friend. Hope this video helps.
I've updated the wiring diagram. This updated version should be a lot more clear than the one in this video. The updated version is located in the google drive folder under the name "Wiring Diagram Updated."

Notes: * These are the linear rails I bought, though because I don't have space in my shop I have to keep my machine outside and these rails have rusted, just keep this in mind ** I know the linked Stepper Motor Driver is unavailable. I just wanted to link the exact one I used. The second link is a driver that looks similar, I just have not used it so can't guarantee anything
