I bought a 4th axis and have everything figured out except the wiring. The wire colors on my 4th axis stepper motor are red, blue, green, yellow. The wire colors on the Y1 which I’m splicing to are red, blue, green, black. I connected red/red, blue/blue, green/green, yellow/black. I set all my Moto…

Just a heads up. We do not support 4th axis. If this is done incorrectly, you may permanently damage your controller and void the warranty. Keep that in mind!

There are people using the Y axis as a 4th axis A successfully. I realize your comment but am moving forward.

Here is the guy I got my info from. [image] 4th axis option Feature Requests I just set up mine to run a rotary as the Y-axis and it works fine. I’m sure you could run it as the X-axis as well. I’m using vcarve and only using it for the laser so far. So I just modified the…

So you can’t go by colors you have to know what wire is the A+, A-, B+, and B- of the stepper motor you are using is and then wire those into the correct port on the motor connector in the controller.

I agree. I always find and print the data sheets from the controller and stepper motors I am using (Buildbotics and ? in your case), then confirm the colour connections from those.

So where do I find the wiring codes on this one? [image]

Hey DaBooBear, [image] DaBooBear: So where do I find the wiring codes on this one? you will always find them on the datasheet. If you get not datasheet with it, I would stay away from the item. However if the stepper has only four wires, it is possible to find out the wiring (see below). A …

If it’s not listed in the posting or in the Q/A of the item you could ask them or do the above. If that is the same one I bought and posted about then it is listed in the Q/A section. I think I also posted it in my write up.

From the Amazon link I found for this 4th axis, the wiring diagram shows red and green are one coil pair, and yellow and blue are the second coil pair. The Buildbotics website gives the connector positions for the motor A+/-, and B+/- (left side of molex is the B coil pair, right side is the A pair)…
