I just soldered a wire on top of it bypassing it. I'll put an inline fuse on the line to the heater pack

They are zero ohm resistors. Often used in place of fuses. You can them from mouser or digikey. You just need to match the physical size. You could even just solder the new one on top of the existing bad one.

I just had this issue. The fuse , I think r271, looked fine on mine but had blown (tested by connecting the 2 points and printer finally worked). Visual inspection may not be good enough is my point.

Hi Carl
I've checked the power supply for wattage and it all just above 12v, I've also inspected the resistor and they look fine to me, http://i1336.photobucket.com/albums/o64 … lfu5xd.jpg

You propably have one of the nozzle heaters wires exposed near the nozzles heat block. Since the brush is brass and conductive, if you clean the nozzle while it is heating and brush one of those exposed wires you will do one of two things.

There is a resistor on the main board near the white connector on the left end. It will burn and leave you with no 12 volts. The other outcome is a now fried power supply.

Unless you can or you know someone who can surface mount solder and replace that resistor once you visually confirm it burned then you are left replacing the board. If it turns out the resistor did not burn, then I would confirm you have 12 volts from the supply by using a multimeter and placing the red lead on the leg of the white connector for the yellow wire and the black lead on the leg of the white connector for a black wire. With the machine on you should read 12 volts or so there.

Last time you used it successfully did you by any chance clean the nozzle with the brush just before you shut it down?

Hi i have a problem with my printer hope someone to help me out here.

I've have done about 20 print on the repetier host firmware on my davinci 1.0a. today I've turn on my printer and none of the axis is moving or have power to them. plus the led light won't light up. I've have try everything i can to get the printer up and running again but no success. have anyone ran into this problem before? If yes can someone help me out here. Firmware seen to be running fine, No error code or what so ever.
