looks like after voltage spike in 220v mains something went really wrong and burned in k1 max, trying to figure out what is it.
it just don’t start, led behind creality label blinks fast and some ticking noise (from PSU probably),
screen is dark.
but if I remove hotend pcb cable from motherboard (24, rx, tx, gnd), screen starts and hangs on creality logo.
what should be resistance between 24v and gnd on hotend pcb on attached picture?
(marked yellow).
now it’s near 1 Ohm, looks like short between 24v and gnd.
it’s when HE pcb disconnected from MB, not sure what’s really burned, but looks like HE pcb?
