Re: wiring Gecko drivers

Robert,

Are you able to move the axes? I just tried to wire my z axis motor
another way and burned out the Gecko for the second time... I do
have my limit switches working but not the z axis home sequence.
What software and what motion control board are you using? I have
not figured out how to get the brake to function yet.
