Damage Heater E1
-
Hello,
I have successfully controlled a Berd-Air by E1 heater for month but I made a mistake in reconnecting after a modification. I have probably reversed the flyback diode.
The sentence was immediate.
When the pump started during the print, I got these messages followed by a shutdown of the printer:-
M106 S0.1
-
list itemError: short-to-ground reported by driver(s) 0 1 2 3 4
-
list itemError: over temperature shutdown reported by driver(s) 0 1 2 3 4
-
list itemWarning: VIN under-voltage event (5.1V)
I managed to restart the board and everything seems to work properly except E1 heater.
It is continuously running from the start (E1 led is on).
I connected a fan on the output and is always on with no pwm.
I don't see visually damaged component on the board.Which component may be causing the problem?
And if it's hard to replace, is there a way to disable this output?
