Hot end fan connector

Recommended Posts

Posted · Hot end fan connector

Whilst trying to diagnose a faulty build plate I noticed that according to the manual from https://github.com/Ultimaker/Ultimaker2/blob/master/um2%20assembly%20manual%20V1.1%20_english.pdf

the hot end fan connector should be located in the middle of the board. I noticed that mine is connected to an end connector on the right hand side of the PCB (bottom of the image below). Since this was fully assembled and has been working for quite some time now, i am assuming that this location is correct. Can any one comment on this. Should I move it or leave it where it is?

Either is fine; both are direct 5V out, unswitched. The central position was intended for the fan. The outer edge one for other general purpose connectivity, but both work just as well. Some early units came with the fans connected on the end - like mine. I'm not even sure if those had the the other connector - I haven't taken mine far enough apart to see.

But, yeah, don't worry about it.
