I had previously adjusted the voltage to 1.5 but I checked it again and it was still 1.5, I have heard that the wire can go bad and people have been soldering them back together so I unplugged the wire going to my Z axis and moved it over to the extruder both on the board and on the steppers and now the extruder is working. Does anyone know of a guide for repairing the wires? are these standard ends I can just order more of?
Thanks for any assistance
Yes, the motor end is a standard. These look like JST PH 6-Pin connectors. They have 2mm spacing. (JST=Japan Solderless Terminal, in case you were wondering. JST site doesn't seem to say what "PH" is for.)
You can get them on e-bay, pololu, newark or digikey. I haven't been able to find them on mouser.
They require a special crimp tool (Official JST hand crimper is ~$500, clone is ~$35 at pololu) Talking to an EE friend today, the PH pins are supposedly a bear to manually insert & align properly. I haven't tried.
You can also get a connector with pre-crimped discrete wires on ebay. (the other end is raw). I have not yet found a ribbon cable harness.
I haven't looked at the system board, but from photos, the board end appears to be standard 0.1" connectors. If you have a crimp tool, these are fairly straightforward to put on. (Very hard without a crimp tool. Cheapster that I am, I tried once.) Look at the jst.com home page for what a good crimp looks like.
Since the SD cables seem to have a fairly high failure rate (at least from the SF message board), your best route might be to replace the SD cable with one from ebay and add the other end. If you go this route, twist the cable pairs to minimize EMI.
You can also contact one of those sellers and see if they'll do a special cable for you. (And maybe get them to list it so the rest of us can buy them. 
)
