Grab this and this . Cut off the plug SD uses, strip the wires back about 1/2", use the crimp pins I linked, then slide them into the 4 pin housings. This will guarantee fits right side up or upside down.
It's a little extra work for you, but someone screwed up crimping the plug. You can:
1) Splice new wires into the old plug (if it still exists
2) Email Solidoodle and wait a few more weeks for yet another replacement (risk they may just send the same one back)
3) Grab the items I linked and prevent this from ever happening again. Plus, these plugs are awesome

Sounds like you plugged it in reverse.
Unplug, flip, then re plug.

You could have fixed this by rolling the connector 180 degrees or swapping any two pins in the connector. Or flipping it in firmware.

If I can't fix the board I'll look at just replacing it, thanks for those suggestions IronMan, I did not know what options were available so I'll start with those if I get to that point smile

If I can fix it I'm defiantly going to be making my own cables, probably should have done that originally but I was having trouble finding the correct ends and pins and would have to get the crimp tool so when they said they would send me one I just dropped looking at making my own.

I only recommend this if you have a deft hand and lean wallet (otherwise you're better buying a new board. I would not even bother if you're using a pololu board just get a new one. The chip itself is like $4.50 and the board is $10)

But i have replaced the DRV8825 chips a couple times before. The key is to load a ton of solder on the pins on one side to get a good thermal mass, lift that side with a xacto knife while you're running the iron up and down the length. The second half is easier to remove for evident reasons. Now you want to solder-wick up the remaining solder, apply flux to the pins, and place your new chip onto the board. The best technique for these mofos is to tack the corner pins with big globs (small as you can, but they will be too big), then drag-solder. The surface tension will wick solder to each of the well-fluxed pins as you drag a soldering iron with some solder on it across the pins.   If you ever feel things are heating up too much just give it another shot after it cools and reapply flux.

Total shit that they gave you bad cables though, it's a bad sign to not have your crimping art down 100%, because bad crimps are a future mechanical stress failure, whether they were tightened too much or nicked too badly.


I haven't had trouble with the stepper-motor cables (those come from the stepper motor factory), but I would be cautious about replacement cables for any other part of the system from pololu. Esp parts that move a lot, i would get high quality silicone wires from hobbyking or some other hobby-shop.  The wire that my solidoodle came with was very low quality and eventually fatigued from the printer head movement.

Good luck with SD Support and hopefully they will send you a new board.  If not, you can consider an upgrade to a Rumba, Ramps, or Smoothieboard...

If you got a replacement cable from them that is black twisted wire inspect it closely, I did not notice but the wires are actually exposed a little when they leave the connector and apparently touched while the print head was moving around. I tried connecting a different axis to my extruder plug on the board and got nothing so I think it is dead. I just sent them an email so we will see how that goes, took them forever (4 months) to get get me a working replacement cable after the first one broke. I've never dealt with a worse product or worse support.
