Posted · Fan printhead, Short Circuit

Hello my name is Jeroen from the Netherlands.

I have a Ultimaker 1.

My problem is the Fan at the printhead.

I bought a second fan for some extra cooling.

when i tried to test it I short circuit it.

for a minute or 2 my printer didn't turn on. When it did turn on again my fan wouldn't stop spinning. it won't go off.

For as far as i know the printer stil functions, its only the fan that's "crazy"

Please help me.

greetings,

Jeroen

    You broke Q4. The darlington transistor. It is easy to replace if you have beginner soldering skills. This large 3-pin part is located very close to the fan plug. It is not an expensive part.

    I think that’s true that yow blew the Darlington transistor and you can easily find it as it is black 3 pin devices and moreover you can also find it on the PCB as it is designated as Q4 on the PCB.
