I am most vexed with myself today. Yesterday I was almost done getting the ALPS 2010 finished and I went and plugged the power in backwards 😭 It must have got at least 24v up the earth line.
It still powers up but only if the print head cable is disconnected, otherwise it makes a faint angry hissing noise...I guess something is shorted.
I might be very lucky and its just a board component I've fried, but the print heads are delicate so it doesn't look good 😟
