No DC Voltage to printer bed

[TKCC71]

I have a new V3 Rostock kit that I assembled. I had to have my bed replaced because it was not pushing the right amount of resistance.

The previous bed would heat up but would take almost 30 min to get to 60 and then would not go any higher, as a result SeeMeCNC sent me a replacement bed. So I've re sauldered the new bed and installed it. The problem I'm having now is that the 12V DC power supply is not providing any power. I tested it with a volt meter at the power supply and there is nothing. I reloaded the firmware and still now power coming out. Any suggestions?


I checked the Rambo but I am getting 12V from there?

The same power supply provides power for the Rambo, so I find it hard to believe you aren't seeing 12V at the power supply. To test 12V power at the power supply, put the red lead of your voltmeter on one of the +V screws, and the black lead of your voltmeter on one of the -V screws.

Check the blade fuse on the Rambo. If that's not it, you need to start rechecking/testing your DC wiring.

Thanks Eric. I used a different ground and didn't show I'm getting 12V to the bed at the solder points and at the power supply but its not heating up. The Led isn't lighting up. I checked my continuity and all seems good. The Led lights up when I test it. The thermister is working and also reading temperature (Test with a heat source).

Any thoughts?

Disregard. It miraculously started working? Thanks
