Power Panic  

RE: Power Panic

Does anyone know what the output on the power panic line from the PSU should be for "power good" and "power fail"? My new XL won't go beyond a "power panic" error.

The knowledgebase says that the printer won't work if the cable is disconnected so there must be some sort of active signal on the line. I have checked the PP cable for open circuit or short circuit.

I believe you leave the black wire connected and the white one disconnected or vise versa isn't better to get replacement from prusa anyway

Thanks for the info: 6 hours on Prusa chat failed to elicit that information! Unfortunately it wont solve my problem because the cable actually tests fine, I think my problem lies on the main board.

Yeah exactly leaving 1 wire disconnected will stop the signal but confirm the cable is in I just carnt rember if it's the white or black you take oug so maybe try both
