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.

Some Information about End Mills (Rotational Cutters) for CNC Machines
I receive a healthy dose of questions about end mills and which ones that I use. I usually respond with answers like, my end mill will probably differ from your end mill. So, what is this thing called an end mill anyhow? If you are new to CNC machining and routing, you may have never heard of the thing. I could imagine googling something like, "CNC bits". Using the terminology "bit" is not all that incorrect. Bits are commonly referred to as drill bits, but routers use router bits. If you're looking to cut various metals and composites, end mills are the tools of choice. However, end mills will also work on wood, depending on the type of end mill selected.
