So here is the electrical diagram you asked for:
I have a couple of words of explanation to go along with the diagram as well.
I created the diagram to lay out all the power electronics and the main power distribution of the QueenBee Pro CNC. This means that there are no terminal numbers or attachment points for the connection to the Arduino nano I am using as a breakout board.
I have included the ground connections to the limit switches and the stepper motor drivers. This is a signal ground meant to be attached to the COM or GND terminal on your controller NOT the negative rail of your DC power supplies.
And that is about it, if you have any questions, let me know somehow and I’ll see what I can do.
If you want some help designing a complete control system for your machine contact me and we can sort something out.
