Hi,

Hope this hasn't been asked elsewhere on this forum. I have searched, but my searching skills may not be up to par.

I'm trying to work out the connections between an Arduino UNO R3 running GRBL to a TB6560 stepper driver, specifically this one:

TB6560 Single Axis 3A Stepper Motor Driver - Green (10~35V)

The GRBL firmware has these outputs:

- Spindle Direction
- Spindle Enable
- Limit Z
- Limit Y
- Limit X
- Stepper Enable / Disable
- Direction Z
- Direction Y
- Direction X
- Step pulse Z
- Step pulse Y
- Step pulse X

The Stepper Driver has :

- EN +
- EN -
- CW -
- CW +
- CLK -
- CLK +

I've got the motors hooked up on the other end, just cant work out these connections.

Any help would be greatly appreciated.
