### ⭐⭐⭐⭐⭐ Worked perfectly when others didn't
*by P***R on May 25, 2024*

I used this to interface the spindle on my CNC with the control software. I had tried a different one which didn't work, so I ordered this one to give it another try, and it worked perfectly. Used with a Chinese HY VFD and Mach3 software

### ⭐⭐⭐⭐⭐ Fácil de usar.
