Step 27: Y-Axis Motor Wire Connections
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. Now we come to the wire connections. To describe the bigger picture, first mechanically, the motors must turn the screw to provide linear power transmission (movement back and forth). The motor needs power to turn the motor shaft, so the motor connects to the driver board that will accept three motor connections, one for each axis. The driver board is connected to a power supply to provide power to the driver board. The computer is also connected to the driver board to provide step pulse and direction instructions.

Step 21: Driver Caps, Resistor Networks and Mosfets

The resistors are in, right? Ah, I know, you want to see the complete assembly before you dig in. Ok, on to this part of the assembly. Please don't ask me what Mosfets are, but the word sound cool! I can tell you that they stand for Metal Oxide Semiconductor Field Effect Transistor. I have personally read about fifty descriptions of this electronic animal and I still can't figure it out. It doesn't say much for a Berkeley grad! Well, I'm open to some plain English interpretations without the word "drain" in them. Are you still with me?

Step 28: The X and Z Motor Wire Connections
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. Why have one, when you can have two for the price of one. Really, I don't think I could do another wire soldering video, but there is some good instructional material here. Otherwise, I wouldn't waste your time.
