Topic: When does the fan of the extruder stepper motor run?

Simple question.
I have my SD2 for 1 week now, it´s quite hot here in germany these days, but the extruder stepper motor fan never started.
Do I have to switch it on manualy or what?

And.... by the way: The extruder assembly has 2 metal shafts, should this assembly be tight, or, like it is out of my box: I can wag the assembly a bit.

Thanks!

Should run all the time. Solidoodle probably wired the fan backwards, try reversing the connector.

I had the same problem. There are two Teflon blocks at the rear of the assembly. You can loosen the bolt  at the bottom, pinch the Teflon blocks together and tighten the bolt. This should remove the wiggle. Just don't tighten it to much, you don't want it to bind.

My fan quite often needs a little nudge to get started.

Should it also run in standby? Power cable pluged, but not printing?

just realized that the fan motor becomes hot but does not start blowing

It should always run if the printer is powered.
