No power, only whining
So I’ve had my MK3 kit for a while and thought I would give it a go during the 4th of July Holiday. This was actually a MK2 to MK3 kit so I didn’t want to put my printer out of commission unless I had a whole day to put this together so I wouldn’t be without a printer for long.
After about 12 hours I got it all finished, and when I went to power on I hear this high pitched whining noise from the PSU (sounded like coil whine). I checked for lights but I don’t see anything on the Einsy or the LCD. Any thoughts on what to check next?

First, re-check that you have the red and black wires from the power supply on the correct terminals on the Einsy Rambo board.
Next is to contact support via chat to report the problem.

Its humming because it doesn't know the words.
Proud owner of a Mk3 that is producing very nice prints. There is room for improvement as I learn more about it, but so far I am very happy.
