>They determined it was because of the part cooling fan being off turning off the board cooling fan.
I am the chinky tools anon. And yes, on early revisions of the ender 3(like mine) the part cooling fan is on the same PWM channel as the board fan. My steppers haven't lost any steps and fucked up coordinates since I've rewired the board fan. Later revisions of the e3 do fix this, however. I'm just not sure what version they switched over.

That was a fairly quick mod once I found the right size hex bit. Thanks anon. Doing a reprint with the board fan on 100% all the time when the printer is on.

Not that you really care because it just seems like you're being purposely stupid at this point, but I just confirmed it is indeed the case, atleast on my ender 3 version. Turning the parts cooling fan off also shuts the board fan off because they're tied into the same PWM channel.

Fucking chinks.
