I don’t think this is the correct forum, but it’s the only one that will allow me to post.
I’m a newbie and bought a P1S last month. All of my filament has been purchased directly from Bambu. About a week ago, I got a clog in the toolhead. Since I couldn’t get access to this forum, I relied on a few YouTube videos about clearing clogs. Unfortunately, the clog was deep in the toolhead, and after several hours of trying to clear it, I gave up and replaced the toolhead with the spare provided. I again followed a couple of YouTube videos, and the replacement seemed to go smoothly. I was able to print a few items afterward.
The problem is that when I check the Bambu phone app while printing (this does not appear in the desktop app), I get an error message during printing:
“The Part Cooling Fan speed is too slow or stopped.”
There are two fans associated with the toolhead: one in the cover and one on the side of the toolhead, which I removed from the old hot end and installed on the new one. Based on my searching online and through ChatGPT, I believe the Part Cooling Fan is the one located in the cover housing. Is that correct?
I had to unplug this fan during the hot end replacement. All three plug connectors were fairly tight before removal, but they no longer seem that way. I believe the housing fan plugs into the top connector—is that correct? And is the correct orientation for the connector with the wires pointing downward?
I have removed the cover and tried 4–5 times to reseat and reconnect this plug, but I honestly feel like I’m missing something. Could someone point out what I might be doing wrong?
Also, I apologize if this comes across as overly frustrated. I did spend extra money on a Bambu Labs printer, and it’s been discouraging how difficult it has been to get official technical support.
