I have the Acro 1010 assembled per the openbuilds video. However, there is no information or video on how to wire the thing. I have the wiring connections to the OpenBuilds Version 4 driver board. But do not see a way to mount the board to the front rail. Openbuilds supplied everything (wires/nuts-bolts) to hook it up. Does anyone have any pictures of how you layed out your wiring? I did manage to get a drag chain on my X axis. Not sure how to rout things from there. I did NOT order the control board holder that is shown on the openbuilds web store. Is this what I am missing?
