Review: This thing has no business being as nice as it is for $255. - Update: I have modeled a cover for the belt and pulleys. Thingiverse ID: 7266411 Update: To learn how to update the settings in PathPilot (if installing on a Tormach), find me in the Tormach Operators Group on Facebook. Original: Every once in a while China really outdoes themselves. This is one of those times. This thing is simple, clean and accurate. Now, honestly, there isn't too much to these, but this little package for $250 is a great deal. I found a random $20 controller to go with this and it works great. Spins plenty fast, even with the 6:1 reduction. Mating it to my Tormach took some work, but in the end, operates perfectly. Tormach is not expecting a 4th axis with a 6:1 reduction ratio, so none of the micropulse pin settings on the stepper driver generate a proper 360 degree turn when commanding a 360 degree move. You have to go into an .inc file on the controller and change the 4th axis SCALE. Then, if you want it to turn faster, you have to change some speeds, also in the .ini files. It's all on the LinuxCNC forum. But very easy to do and saves $3000 versus a MicroARC. Highly recommended.
Review: Best 4th axis for home CNC - Very nice unit. I could not find any backlash or any play. Got it in just two days. It worked right out of the box. Price is better that Ebay. I'm going to use 2" aluminum blocks under the unit to turn pieces up to 9" diameter, without them you can do 5" diameter.

### ⭐⭐ Dead Motor on arrival
*by K***. on April 26, 2026*

The quality of the chuck and tail stock looks really good but the motor was shorted out when it arrived. I wired it in and immediately got an alert on my stepper drive and the motor would not turn. I wired in another motor the the drive and everything runs perfectly. I have over 12 years experience building CNC plasma tables, milling machines and lathes
