High Voltage Wiring Diagram

A project log for Sub $200 PCB Mill that doesn't suck!

A PCB mill inspired by open source CNC 3D printers with a custom design to fit standard size copper clad boards (6" x 4" / 160mm x 100mm)

was asked to create a wiring diagram for the NuggetMill5, so here it is.


I left the basic stuff for stepper motors and endstops out because I already described it in my logs below.

Motors are standard. Just make sure they move in the right direction with my configuration. If not, please turn the plug around and it should be fine. I stole the 5Volts for the relay from the I2C port. I also needed to use the MIN EndStop inputs for the three endstops that are supported with this version of grbl instead of MAX as described for the original grbl. Please keep that in mind.
