Review on Precision Manual Linear Motion 3 9Inch by Clint Mcloven

Better quality than I expected. I would like the wiring to be wrapped, but I did it myself. I would buy this again. If they had sold this with a driver it would have saved me the time of buying a driver for it and setting it up, but I ended up finding it. There are no specification labels on the stepper motor and no ordering documentation, so please keep a copy of the original Amazon listing. As you would expect, all nuts recorded are metric. They can be replaced by removing the end caps. Update: After a few months of light use, the bolt released jammed balls due to the lack of an Allen screw that inserts the balls into the bolt bearing. Because the plastic end seals on the scroll drive loosened over time due to improper attachment, the balls were not pinched. I rebuilt everything I could with the balls I could find and now I have to order a metric hex bolt to get it right. Now I understand that the valve has weak seals and even with a threaded plug it will most likely fail again.
