My filament is stuck above the hot end as I took it off and it’s still stuck and i have no idea how to fix it and i don’t have the skills to pull it apart, as i won’t be able to put it back together again correctly.
i may have to send it in for repairs.
If your expectation is that this technology works like a “set it and forget it” desktop laser printer, unfortunately, we’re not there yet. That said, Bambu has done a lot to make troubleshooting as accessible as possible by providing excellent step-by-step videos and a top-tier Wiki. Believe me, if you’ve seen any of my posts, you’ll know I’m far from a Bambu fanboy—their support leaves much to be desired. But credit where it’s due: their guides for tasks like changing a nozzle are about as straightforward as they can be.
Think of it this way: if this were a car, your situation is like needing to learn how to change your own oil. While it’s possible to avoid getting hands-on, relying solely on external help will lead to more downtime and frustration in the long run. That’s just the reality of 3D printing today—users are expected to develop at least basic troubleshooting skills.
Take a deep breath, give the self-help resources a shot, and don’t hesitate to ask the community for clarification if you’re stuck. We’ve all been there, and while it can feel daunting at first, you’ll gain confidence quickly once you tackle these smaller issues.

In the meantime, before you give up and send in the printer, consult their Wiki page on this topic. Although this is for the X1, it’s the same process for the P1 since they share the same nozzle technology.
These two videos are embedded in that wiki page but view them first and I think it will bolster your confidence. It really isn’t as hard as it may first appear.
Also, even those of us who are already comfortable with this technology often will take the lazy way out and have spare full nozzles on hand if you don’t want to mess with unclogging. Bambu makes it real easy to replace them at a very reasonable price. I mean for $15, you can get the entire assembly and it only take three screws to install, just be careful with the wires and follow the video. You’ll be a pro in no time!!! What’s more, you’ll feel that empowerment that comes with knowing you got this!!!
Thanks for the info, I tried a cold pull but the exactor/extruder but is making a grinding noise, so it looks like i will need to pull it apart, but that will have to wait till tomorrow, as it’s 11pm here.
the 2nd video is what my problem is, just it won’t extract at all, the extruder is off and cleaned out, and the filament is stuck in the feeding in part.
I also had something like this with my X1 in the first week … Filament could no longer be retracted - and could not be extruded any further. So it was stuck in both directions. Cold pull didn’t work either, you could tighten it however you wanted.
In the end, it was an extruder clog.

Was then fixed again in 15 minutes. Should look very similar with the P series, right?
Here’s what I would recommend since this is your first time doing this. For the purposes of reducing variables and leaving nothing to chance, simply purchase a new hotend for $15, spare extruder for $35 and a hardened steel extruder for $20. I purchased two of them for spare’s sake and they are still in the box. This was mainly for peace of mind and I consider this like I would the expense of consumables over time. I know I will need them at some point.
While your at it, in order to save on shipping, stock up on other spare parts in the mean time.
Once you get these parts, just swap out the clogged part. At least you will know that you are working with a known good part. Then take your time and later disassemble the other part or experiment with unclogging it. This is a good skill to master.
Here is a tool that I had purchased some time ago fully expecting to need it and I still have it in my tool bag never used. It is a 1.75mm probe that can be heated to unclog an extruder. It may be worth having in your tool kit just in case.
Well i can’t buy a new extruder as the Australia store doesn’t have them listed, my printer came with a spare hot end, just it’s missing the little fan and the other wire attached to the outside of the hot end.
edit: scratch that, i use your link above and replaced the US to Au and it’s now showing.
Did I miss something here? Is there something damaged or why the consideration to buy everything new for a replacement?
In mechanical and electromechanical maintenance, best practices dictate replacing the suspect component rather than attempting a repair, particularly when the original poster has expressed a lack of confidence in their repair skills.
This approach is recommended for several reasons:
- Simplified Diagnostics: Replacing the component narrows the focus to determining whether the overall system functions correctly, avoiding the complexity and uncertainty of verifying the success of a repair.
- Reliability: A new component provides consistent and dependable performance, eliminating doubts about the effectiveness of the repair.
- User Confidence: For those unsure of their repair abilities, replacement aligns with best practices by offering clarity and assurance that the issue has been properly resolved without the complexities of a repair process.
In short, this approach is comparable to replacing an ink cartridge in an inkjet printer rather than troubleshooting whether the issue lies with the cartridge or the printer itself.
It is also worth noting that having spare components is essential in general. Procuring backup components not only supports this repair but also equips the original poster with spares for future needs, allowing them to build their repair skills incrementally without the pressure of extensive troubleshooting.
Extruder clog is inevitable stepping stone you have to step over with FDM printer, unless you pay premium for so call industrial printer and the special filament going with it. Such example is markforged printer and only use their onyx filament, which cost is about 10-20 times compare to P1S and random filament brand like esun/sunlu
@Olias, somehow I find your reply is very much likely from chatGPT , which I know it isn’t
Sorry, but this problem here still sound like a simple extruder clog to me. To follow a video or a thread with dozens of pictures is not that hard - replacing everything is also not as simple as it seems. And a week later with bad luck the same clog could happen again.
3D Printing will always be also tinkering around to solve problems.
That’s exactly why it’s good to have spares of the parts that need frequent removal. He wasn’t suggesting the OP swap the extruder and throw the clogged one away… he’s saying have an extra so you can swap it out and keep printing. Then take the clogged one apart and fix it. If it happens again swap that one back in and keep going.
Well… that may not be hard for you or I but we must respect that not everyone has the same comfort level. My response was intended to strike balance between respecting the original poster’s desire to avoid getting in too deep while at the same time ecouraging them that there was a path that could offer assurity with less risk. This was purely out of respect.
@PrinterMcgee however, summed it up best. So I won’t repeat that part.
Thats why I’m asking what I’m missing
Took that thing apart and Take that thing out is a difference in 3(?) screws? If you have it already in your hand, there not much more to do
Everything’s fine, thanks
I have taken the Hot end off ( it was partly clogged but is now clear) as I’m waiting on a replacement extruder before i take it out so i don’t lose any parts, it should arrive by Thursday the 12th of Dec.
once i have switched over the extruder i will, watch the video a few posts above that shows how to open it and remove the stuck filament.
ok just an update, i have just gotten round to replacing the extruder and now i have a question about the hot end that the videos above don’t cover, mine has a small metal wrap around the hot piece that has wires coming from it, the replacement that came with my printer does not hove this small wire or the wrap that keeps it attached to the hot end.
how do i go about attaching it to the new hot end?
