Hi all,
In the past month or so my P1S keeps clogging the filament…
Tried different rolls/makes, opened the extruder, cleaned the gears…
A new nozzle, works for like month tops and it starts to clog.
No matter what I do, it just keeps clogging; literally makes me throw it out the window 
Top cover has been removed, so cannot blame the heat.
Any advices?
What size of nozzle and what type of filament? Is the extruder jamming (heat creep) or is the nozzle clogging? You are unable to clear the clog?
0.4, simple PLA, dual/tri colour filaments.
It’s like under extruding.
Yeah I clear the clog, but the next print same thing happens…
Maybe it’s not screwed on tight enough, resulting in a snag condition. Check the wiki.
It’s fully tight, I know there are issues with TPU having the tensioner screw fully tight…but not PLA
I always had problems with silk filament clogging due to them being much thicker. I switched to 0.6mm nozzle and clogs are a thing of the past. Quality is almost identical with 0.12mm layers.
I see there was no real answers, did you ever figure this out. Im having same issue. My p1s has clogged more in the last 4 months than my 2 vypers combined in the last year. How can a such an expensive and “high quality” be so unreliable? My creality k1 max is blowing the bambu out of the running completely
Same here ! printed with 2 printers from last december to about May of 24 . After that it has been a night mare ! Clogs every other print. Nevermind , trying to print longer than 1.5 hours . I know I don’t have nozzle issues nor extruder issues because I bought brand new parts for every single one of my printers. I’ve also bought a $200.00 dehumidifier for my basement to make sure to keep that sucker under 30% humidity. I bought an expensive spool dryer that didn’t do the trick either. I seem to be able to print with all the other colors or silk filament but basic black PLA is a disaster. Sometimes I get through a one hour print and then I have to give it a break then I can print again. If I try to print back-to-back I will guarantee get a clog. I’m starting to think and assume that it is heat creep. I’m assuming that the summer conditions in my basement are quite different than spring and winter. But it’s a bit confusing because when I look at the thermometer with the AC running and the dehumidifier clearing the air the conditions seem identical to winter period in any case I’m completely besides myself and I have no recourse. Every time I read these posts everyone points at the Super silly obvious stuff. I’m not knocking anyone i’m just saying it’s something deeper and I can’t seem to figure it out. The killer part of all of this is I’m trying to run an Etsy business which has been extremely successful. But that might come to an end because of these issues
I’ve had my P1S for 3 weeks… I ran out of filament on a print… then a clog. I cleaned out the clog. Printed 1 item all good, Ordered a new PLA black from Bambu, boom 2 clogs!! Yet the PLA Silk didn’t clog before it! Does that mean the PLA black I got from bambu is bad? I am very new and don’t want to advertise anything until I get this issue figured out! 0.4 Nozzle that came with the machine. Of course bambu china is on holiday until the 8th…About to do a return! I have researched all over the place and can’t find an answer why it is doing this. Any idea’s would be greatly appreciated!
So, I got some help from other users on here and after I cleaned the clog…I have left the top open. Its called heat creep! Its too hot inside. I am now printing again with no clog or issue!
Did anyone figure this out 
I’m in the same boat. I got the PS1 so I would have to do little maintenance as I’m not wanting to spend a ton of time fiddling with 3d stuff.
All,
Not sure if it’s related but I started having clogging issues after replacing a broken AMS internal hub mount. I printed the mount after it cracked, started getting clogs every other print. The wiki cautions against over tightening as you might affect the feeding…I’ve loosened it and so far it’s OK but I’ll report back if there are any further issues.
So a few reply’s referred to using black filament and it clogging left and right…I’ve been printing on matte gray for a couple months …switch to matte black got through a few prints and then boom, clog after clog …at first it was only 3rd party prints but now I just tried to run a test print off of maker world and it happened on that…is it just black filament is garbage?
I’m having the same problem with my P1S. I got it in November 2025, and it worked quite well for a few weeks. Then all of a sudden it clogs every single print. I’ve gone back and forth with support, they finally shipped me a new nozzle, extruder and front housing assembly. They confirmed that in the logs it was overheating despite the top lid being off and the door being open. I received the parts and installed them, I was able to complete 7 successful prints but it started to clog again and now clogs every single time again. Unsure where to go at this point…
I’m only a novice with the P1S, as I’ve only had mine just over a week. However, I’m not new to 3d printing, as I’ve owed a couple of Ender 3 pro’s for the last 6 years.
Not sure what you have done recently, but something I’ve found out once prints started to fail, is to re-level the bed, e-steps and z axis, then it worked for a while (I know the P1S has auto calibration) but after reformatting the SD card, and then recalibrating my ender it would again work for a couple of months. I know the ender configuration file is held on the SD card, I’m not sure if the P1S works in the same manner.
Just a thought, change the SD card or reformat the SD card and recalibrate may be worth a shot. Please anyone out there correct me if I’m wrong.
I’ really new at this, so pls excuse the niavite…
I see that several people referenced heat creep - can someone explain please. And how hot is too hot in the PS1?
The nozzle needs to be hot to melt the filament inside it
The extruder needs the filament to be thoroughly solid, in order to grip and push it.
Heat creep is when the extruder encounters filament that has been warmed to become soft. The gears then squish and shovel material into spaces that are not the nozzle, and when that solidifies, you get a bulge in the plastic - clog - that is too large to travel down OR up through the machine. Disassemble + clear, etc etc. Theres a lot of creative thermodynamic ways this happens, but mostly its due to insuffucient cooling in the heat brake [broke fan] or the chamber just being too warm so that the fan systems can’t actually keep cool areas cool
