The wiring of the machine was quite simple because there were only two stepper motors to control and a relay for switching the plasma cutter on and off. For that, I used two TB6600 stepper drivers, a 12V 5A power supply, a relay module, and an Arduino Nano. I used grbl as the firmware because there are a lot of different CNC / CAM / Control tools available that support grbl. I wired the stepper motors according to the grbl pinout and wired the relay module to the water cooling pin (M8, M9 Gcode Command). The stepper motor drivers are powered by the 12V power supply and the Arduino NANO is powered by the connected USB device.
