Just for clarification, I did not make a CNC motor controller out of a UPS; I’m only using the UPS housing as an enclosure for a commercial motor controller.
I purchased a table top CNC router from eBay, and the controller came mounted on a board. I didn’t pay a much for it so it wasn’t too big of a deal. But I soon found that the motor controller would be much better off in a protective case. It would also be nice to have an on/off switch. I initially planned on creating my own custom box using my router but I figured this would be more time effective and more durable.
This project is pretty easy but does require some soldering, drilling, and cutting.
I completed this project in about 4 hours, for a cost of about $5.00.
Step 1: Tools & Materials Needed.
Multi-meter for finding out the pin-outs of the switches, and double checking wiring.
Screwdriver you may need both a Philips and a flat.
A Utility knife (razor blade) for cutting the Sintra.
Wire strippers these will get a lot of use in this project 4 wires X 3 motors X 3 connections
Step Drill (or a regular drill bit) for drilling the vent holes and any necessary mounting holes.
Cordless Drill (optional) this makes taking apart the UPS very easy and quick.
A soldiering iron.
