My setup with the G540 is all complete and works fine but the motors direction is not the way I wanted. Like when I press the page UP keyboard button the Z axis goes down. I know I can change the Active Low from green to red or from red to green or perhaps from the Homing / Limits page click on the Reverse column? 

It’s also easy for me to switch the motor wiring but I don’t know which pair. From the attached Keling wiring schematic which pair of wires will change the motor direction?

Hi,
just change one pair, keep the blue and red together and the green and yellow together, but swap the terminals
in which they go.

Thanks Craig, will give it a try

Checking the Reverse column is a lot easier than changing wires.

You are right Gerry, wiring was not as easy as i thoought and the Reverse column did the trick, thanks
