Hello guys ,

In many of my works I needed a 4th axis so I did some researches and figured out I will make one with a harmonic gear my self.
The machine is 770 3rd gen , as far as I read it's 4th axis plug and play.Just need the proper wiring and a new driver+ motor.


I've found a same number leadshine motor and driver (for half the price ) and decided to give it a go.
I've build all the parts on my tormach great result btw you can see from the pictures.


Problem : machine doesn't command this driver.... I did all the wiring similar to the other axis , when I control my 4th thru another XYZ driver it works....
Cannot find any differences in the drivers ... pictures attached. Only the PULDIR cable connector was different but I followed the order of wires and tested it in another XYZ drive and it worked....

Any guesses ?
