.7 ohms

The heatbed is the MK2 A bed, the printer is the i3 pro B.

How do I go about testing the resistance of the bed?
Also what should the voltage be coming from the power supply?

At this time its printing perfectly again, just can't hook the heatbed wires up or its instant poof of smoke.

Not sure what that has to do with the heat bed but no, I did not install anything backwards. The stepper drivers came pre installed from you guys. The power plug for the extruder motor wasnt seated properly. Right now all I can do is print on blue tape with no heat bed.

All motors are working fine now there was a problem with the plug.

The heat bed still can not be hooked up as it results in instant smell of impending fire. The wires are not touching anywhere.

Ok, well first off, the blue part is right next to the fan. Second, this happens as soon as I turn the printer on. I haven't told the printer to heat the bed yet through the lcd or my computer, it is just heating itself. Second the mosfet gets so hot so fast that it has started to smoke and I prompt...

Im having issues with this. After a month or so of perfect printing my heat bed sky rocketed way higher then I had it set and the mosfet actually caught fire burning the board. I ordered another sanguinololu 1.3a board from you guys. After installation and burning of your firmware, I switched the po...

Ok, just as some other people on here are having problems my none of my stepper motors will move. I have gone over the wiring and everything is in order. I'm assuming I need to load firmware and am not sure where to begin as I am new to all of this. Any help would be appreciated. Thanks. I have the ...

I have assembled the i3 pro b printer and none of the motors will move or do anything. The heatbed heats just fine and the extruder heats just fine just can't get any movement going. Help please.

I have this same problem. Did you come up with a solution?
