UM2+ & Octopi: Rear Fan Issue

UM2+ with Octopi: Rear Fan Issue

After just a couple of attempts, I’ve managed to bring my UM2+ to work with OctoPrint on a Raspberry Pi.

Everything works well: file transfer, printing, camera, remote controlling of the process…

However, one thing I can’t bring to function: REAR FAN!

The two fans directed downwards work properly, but the rear fan remains still through the whole printing procedure.

Does anyone have the same issue and – even more importantly – a solution for that?

And does it work when you print from the sd card?

I should normally come on when the nozzle reaches 40°c

Yes, it does work when I print from the SD. That's why I believe it's an Octopi issue...

Problem "solved"!

Actually it disappeared.

After one week I decided to connect the OctoPi to my UM2+ again and now it works!?

I did not change ANYTHING...

IT-god works in mysterious ways...

Well that's strange... but good it works now (i've set your answer as best to resolve the issue)
