I feel like a child admitting I did something I wasn’t supposed to do to a parent right now. Please don’t yell at me…
So, I do a lot of medium draftboard on my GF and noticed the other day that my exhaust fan was sounding, different. I do the regular maintenance on everything else in my machine but not the exhaust fan. It was bad. My machine is located in a basement and I do not have the means to bring it outside for the recommended fan cleaning. Here comes the part that makes me wince. I have all the tools to remove the fan so I carefully did so. I wiped everything down so that it was nice and new looking. I then reinstalled the fan and hit the magic button on my next piece. What happened next baffles me to no end.
As soon as it got to cutting the draftboard smoke started pouring out the front of my GF. I canceled that print right away and assumed that I installed the fan backward somehow. Upon further inspection my fan was put back the way it was before and the rotation is correct. During start up, with the lid open and very carefully, I put my hand near the fan when it spun up and felt a surprising amount of air that was blowing into the machine… I’m at a loss. I’ve been messing with this for 3 hours now with no new results. I have a plus so there is no heat sink in the way. I even let it go for a bit and went outside to see that a lot of smoke was still going outside but now also going into my shop. Removing the fan was a no no I’m sure but it’s too late for that. Does anyone have any thoughts as to why this is happening?
Sorry GF mom and dad.
