What do we need to do to get a replacement going?

I know that. I said that the sanguinololu was fine after it was replaced. The power supply is what went bad and needs to be replaced.

Yes, the wiring is correct. I sent all the pictures of it when we diagnosed the sanguinololu board was bad. The power supply worked long enough for me to level the bed, and start printing part of a print, then just up and died.

No output from the power supply. Multimeter confirms it is not working.

Won't turn on at all. The power supply is dead.

It's always plugged into the usb, that's how repetier runs and sends the code.

I have the exact same problem now. A couple weeks ago i received my replacement sanguinololu, after it was determined the z axis was shot, and then put it back together with new z axis threaded rods. I fired it up, leveled the bed, and started printing. 25minutes into the print, the green led went o...

same result. I exchanged the steppers as on of the first things when i was troubleshooting. I just retried and the same results happen, the z axis will only move up. I have swapped motors too, and the same issue

I sent a m119 through repetier host for each endstop. They all showed open. Then i would hold each endstop down and sent another m119 each time and they would show triggered for the one i pressed. That rules out the end stops. I have updated the firmware, no luck. I have swapped around the steppers ...

It does appear that my z axis endstop is bad. that being said, I have replaced it with the one from the x axis, and I am still getting the same results. The only difference is that if I hit the endstop, the movement stops, but it will not go down in z at all. I really think the board is the problem,...
