This thing has no business being as nice as it is for $255.
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.

Tailstock bearing damaged (UPDATED very good customer service)
Just received the package. I noticed that the ball bearing that holds the tip of the tailstock is blocked or damaged,I was able to lose it with WD40 but still, it has a lot of friction. There is no instruction or information on how to fix this.Customer service helped me to solve the issue and I am pleased with the results. Four stars due to the initial issue

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.

Right size for what i needed for my small CNC milling projects
It would have been exactly what I was looking for but it didn’t run. Amazon packing was ok, but box containing item was falling apart. Did they give me a used one…I don’t know. Returning it and reordered another and hopefully it will work and we will be in business.
