Thank you so much! I was pulling my hair out with that one. The only thing left is the filament sensor.

@Phaedrux Thank you very much. I appreciate your help in figuring this out.

@Phaedrux Brand new board and it was mounted before I took the pics.

@bearer Ughhhhh.....dang. It was fine last night, then this. Thanks for the help

It was wired directly to the diagrams. I don't understand. I triple checked everything before I put it on the board.

It has no temp to speak of.

Everything disconnected but usb. No communication to the board at all.

Yes, I did and everything was ok. I followed the instructions and wiring explicitly.

So I checked my wiring, plugged it in, and I get this. No response from the board, and just these 2 LEDs lit up. Can anyone help with this?

Thank you so much! I was pulling my hair out with that one. The only thing left is the filament sensor.

@Phaedrux I have just the standard heatbreak and layer fan. 1 connector from the mks that reads fan. I have another 3 wire cable that runs from the PCB on the carriage, but my assumption was that it runs an LED. Maybe I've just been staring at it too long.
