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 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.

Step 23: Driver Part 4
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. The driver is almost to a completion! We have installed all of the tiny components. Now to the big components. This is the logical process of putting together any circuit kit. The small components are difficult to insert if the larger components are installed already. Believe me, I've tried. Especially if there are jumper wires or resistors needed underneath chips and sockets.
