Welcome to the SeeMeCNC Community

Yep, i got a 4 axis board and want to know what pins to jumper off on the Optical Iso's. or maybe this problem was fixed on the version?

The H-1_3-Axis-EasyDriver-Electronics_Manual-Draft-1-1 is for the 3 port.

Anyways im a newb and i need help.

Thanks a tone

Some are running it without doing the jumper thing, but it's pretty easy to do and can save you some grief.
