(1) 36v 8.8a Power Supply
(1) Interface Board depending on the one selected (USB or Parallel)


Choose From 3 Interface Boards

Parallel Board: Works with Mach3, Mach4, or Linux-CNC. Parallel Port and Parallel Cable Required on PC running a 32 bit OS. Software can be purchased from BuildYourCNC.

Pokey57CNC Controller :Recommended if you wish to use Mach3 or Mach4. This is a feature rich controller that has 4 onboard relays, 8 available motor connections for a maximum of 8 axes, inputs, outputs, and much more.

Mach3 USB Board: Works with Mach3 ONLY. Connects through standard USB port. Mach3 can be purchased from BuildYourCNC.

  • [3 Axis Electronics Combo (All Large Motors)] Would the single 8.8A power supply be undersized for 3 6.0A Drivers? would you recommend getting another PS?

    That depends on a few factors. In most cases, three 3.0 amp motors and drivers will not exceed 8.8 amps of available current. All of the motors would need to be at full torque to reach the 9 amps (3x3). This depends on the mechanical method you are using for each motor, and how you are using the machine. In most cases, only two motors are moving at a time (i.e. 3D carving where the X and Z are moving simultaneously and the y only moves to go to the next row). In traditional cutting profiles, only the x and y are moving simultaneously and the z-axis moves at the location it needs to start cutting the next layer.

    With that said, it is ok to add an extra power supply if you feel you need more available current.

Here is a tutorial on connecting drivers and stepping motors to the USB Interface for CNC machines. We offer the USB interface/controller for those that have a laptop, or don't have a parallel port on their computer, and who prefer to use the Planet-CNC software. Here I show a video on the entire process to get your USB Interface connected to the stepper drivers and stepper motors correctly and in a simple and trouble free way.
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.

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.
