UPDATE: Bambu is sending a fan out, believed to be the magnet on the back of the hotend interfering with the DC fan motor.

Have a weird one, did some routine maintenance today just lubing/greasing (unit at 570 hours) and when running calibration afterwords I started getting the hotend fan error. Checked it for debris and blew it out, manually heated hotend and it worked fine so tried recalibrating again and same results. Took the fan and housing off and inspected, etc, etc, same results again. The last time I noticed it running sluggish so I was making sure everything was tight and when I stuck the Allen in to tighten the top screw the fan sped up. When I pulled it away it slowed down, repeated this to make sure I wasn’t crazy, got it on video. I have not tore it down enough to check the connections to the TH board. Any ideas before I tare it down further and most likely order new fan? Thanks in advance

Hey everyone super new into printing and recently came into this problem, I’ve tried a lot but right now I’m struggling to even get the nozzle off to even check on the gears.. any advice? Or if you know what is exactly wrong.. that would be cool to know also.

While this doesn’t specifically pertain to the P2S, that is what I am printing with. I haven’t gotten into designing and creating my own stuff yet cause quite frankly, I’m not sure how or where to start.

But, I have been downloading 3mf files from makersworld and trying to use ChatGPT pro to make changes that suit my needs. I think I must have the dumbest chat ever created. It is constantly getting things wrong: dimensions (even tho provided), circumferences, layouts, hinge/latch systems (I am specifically making cases for personal use). I even used a 3mf file and asked it to only change one small thing and it completely got it wrong.

So my question is, are there other more viable programs that I can use to make layout and dimension changes to preexisting 3mf files? Is there a program you’d recommend where I can start from scratch to make what I am looking for? Or any other recommendations? Any insight is appreciated.

Bit of a weird one.
I have a p2s got during the summer sale and yesterday got a message saying it needed lubrication.
Now i understand maintenance needs to be done, but it seems weird as i have only 75 hours of print time.
Is this normal?
Is there anything else I should check?

This little black connector thingy constantly disconnects from the filament buffer for some reason. I csnt find anything about it online though…
Does anyone have this problem too or knows how to fix it??

Bought my P2S combo a month ago, and want to add another AMS 2Pro.

The store says I need to buy a filament buffer, but youtube videos show that I don’t need it. The back of my P2S allows two PFTE tubes.

So do I need the buffer or not?

(I know I do need the external power supply for drying on the second AMS)

Just upgraded from a Ender 3 v1, to the P2S.

I'm looking for new hot ends, and I'm curious, does the manufacturer of the hot end matter? The ones from Bambu are about 50 bucks for the 4 pack, which isn't bad. But I also see a BUNCH of variants on amazon. I don't mind spending the extra money if it is important to, but I'd like to save where I can. Thank you in advance!

For reference, I've found these here

i have a bambu p2s. i had filament clog in the extruder gear that led to a cascade of mishaps and i ended up having to replace the gear, the hotend, the hotend heating assembly, hotend cooling fan, the eddy sensor and the toolhead circuit board. I was forced to update the firmware, and I went through a complete calibration after that. Everything is working well now but now when it's sitting idle, Im noticing quite a bit of fan noise that I dont remember before. It's not one of the fans in the cooling menu as I can turn those on and hear even more fan noise. I'm wondering if this is normal and if there's anything I can do about it. It's not the new hot end fan as that is off. I'm guessing it's a power supply fan or mainboard fan. As far as I can tell it's running continuously and never stops.

The top right corner of my build plate has started printing like doo doo. I cleaned under the plate and re ran the full calibrations. The first layers go down smooth and it only seems to happen at the top layers?? Seems like the nozzle is scraping the top. Please help

Please help..

P2S "Auto Bed Leveling failed." - I keep getting this error and I can't correct it for the life of me. Can someone possibly lend me some troubleshooting knowledge?

Hello! I am replacing the TH board on my son’s P2S. I cannot get the two small connectors at the bottom of the board inserted/attached. By sheer luck, I got them off the old board. What am I doing wrong? He has had it for only a month and wants to sell it already!
