## Customer Reviews

### ⭐⭐⭐⭐⭐ A Well-Made and Useful Stepper Ballscrew Mount
*by G***N on February 20, 2025*

This is a great adapter/jig for mounting and aligning a stepper motor to a ball screw. In my case, I'm converting a manual lathe to CNC, so this unit simplified the mounting of the motor driven end.Recommended

### ⭐⭐⭐⭐ Easy way to mount stepper motor and align with lead screw
*by D***K on January 22, 2025*

This is a great way to mount the stepper motors - makes the 'build your own' CNC much easier. Makes aligning the motor with the lead screw a no-brainer. Downside: expensive - cost more than the stepper motor. I first purchased a steel mount then discovered the same thing in aluminum which was much lighter which I liked.

### ⭐⭐⭐⭐ Awesome product but needs some adjustment parts
*by K***S on October 13, 2024*

This is an awesome adapter but the coupler to ball screw needs to be longer (40mm) and it’s made to go on the very end of table so if you mount it further up on the table then you need a wood shim to make it level. I would still buy this again.
