Nope, should be fine, just 5v 0v and your step/dir signals.

You using it as a spindle or something that you only need 1 line driver?

It's going to be my Z axis motor for the lathe

Ha ha ok, hope your putting a servo on the X as well, threading pullout just so much snappier with the accel of a servo
Hood

Unfortunately not  got a nema 34 slim type motor for the X it's the 650oz/in variety, wish I had a servo for the X maybe upgrade in time haha

Got the line driver, slightly confused about what the pin G does, do I connect it to +5v? May I have a diagram of how you had it configured, Regards Lewis

G is to enable the chip, just connect it to 5v. The -G you leave disconnected.

Okay thanks a lot managed to get the motor running with mach  , getting some problems with the drive tripping, wondering if it's tuning, the motor is making a subtle whistling sound and at different velocitys in mach it squeals periodically, at low rpm it seems fine however the drive trips randomly, regenerative energy maybe?

Regards Lewis

The motors may whistle faintly whilst stationary but should not be squealing at any speed.
What error does the drive show when it trips?
Hood

It doesn't show an error the LED display just flashes and you have to reboot the drive 

Guess I was a silly billy indeed the dynamic break wanted 24v to disengage I thought it needed 24v to engage  , oops rookie mistake haha
