The assembly instruction for the Onyx recommends that the 3 black and 3 yellow go to the heated bed connections on the rambo board. Does this mean that there will be no wires going to the mosfet and motor logic connectors? This doesn't make sense to me. I have my Rostock powered up and I can connect with Repitier but the steppers won't work in manual mode and I can't get the lcd to show anything other than white boxes, I have uploaded the firmware and it passes the verify but the screen doesn't reset and come up like the directions show.....
If there is supposed to be power to the mosfet and logic connections which wires would go to them if the 3 black and 3 yellow are feeding the heated bed?
Thanks Bill

Re: Power input connections Rostock/onyx
Two other black and yellow. There are plenty of them at the power supply.
Re: Power input connections Rostock/onyx
all the yellow wires are 12v all the black wires are ground. You'll have one yellow wire and one black for motors and logic, You'll have one yellow and black for mosfets, its recommended to have 3 yellow and 3 black wires for heat bed and as aehM_mey said you can use any one of the yellow wires in that wire harness from the power supply. Each is a separate circuit so each need power inputs.
here's my example. My yellow wires are red because i modded the power supply to get rid of that mess of wires.

Re: Power input connections Rostock/onyx
This post answered my question. I've not worked with computer power supplies before, and the one that came with my kit didn't have a 6-pin connector like the directions described... So thanks!
For clarification, the green wire is a remote or switched lead, right? It flips a relay inside of the power supply to turn it on when it sees ground?

yes green wire goes to the switch, the other side of the switch goes to ground.
you can use the gray wire as a power on led, you can use the purple wire as a standby led. (5v leds)
all orange wires are 3.3v, all yellow wires 12v, all red wires 5v, http://forum.seemecnc.com/viewtopic.php ... 8&start=40
