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.

3 and 4 Axis Stepper Motor Driver Board Based on the Allegro Chip
So, what exactly is a 3 and 4 axis stepping motor driver board. Actually, I am presenting the 3 axis stepping motor driver board in this article, but there is another much smaller board that will connect to this one that will provide an additional driver, making it useful for those wonderful 3D projects that use an indexer.

Step 20: Stepper Driver Part 1 - Resistors
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. Well... here we are, finally getting started with the electronics portion of the video series. The entire structure of the CNC machine is complete with the exception of the router mount. We will get to that a little later. For now, we will start on the assembly of the HobbyCNC 3 axis chopper unipolar stepper driver.
