How to Change Nozzle on Bambu Lab P1S (Complete Hotend Assembly)

[@antmax]

Thanks. I have been holding off changing nozzles because for some reason I thought I'd have to remove the PTFE tube. Glad it's so straight forward.

[@mindlessgreen]

Remember that it's as easy if you buy the 'Complete Hotend Assembly'. If you buy the hotend, thermister, fan etc separately, it takes more work.

[@Soccermojo]

Only like a few more minutes to assemble . I just bought the Hotend and nothing else decause it was cheaper (on Amazon)and I just used the same fan and thermister.

[@darkreddust2135]

I made that mistake but it was pretty easy to install the thermister and fan is just 2 screws.

[@Projectsmanger]

On Bambu lab software. You also need to go to your device and from left top Printer Part. Need to change the nozzle part and also do the calibrating.

[@deeber35]

Did you have trouble reconnecting the 2 connectors? Having a tough time of it.

[@IMChrisThom]

Thank you for being concise and to the point

[@engineer3dprints]

That is my goal with this YT channel 🙂

[@tricky_business]

Thank you! I think a subscription would come in handy as i recently bought this model from somebody else. Totally new to 3d printing so i reckon i can learn a thing or two from your experience/expertise :)

[@drakegettelman3879]

If I get a smaller one do I have to do any calibrations

[@MattManuel]

Good video. Quick and to the point. As another commenter mentioned, unload your filament first then be sure to power off the printer before disconnecting the wires.

[@TheHaxxsaw]

Did you run calibration after installation of new hotend?

[@engineer3dprints]

The first calibration after installing the hotend was completed in this video

[@zachhalliwell553]

@@engineer3dprintsI think the OP meant the actual calibration function in the printer’s settings on the screen, not the benchy.

[@krige]

Isn't some step required before starting to change the nozzle? Like extruding the existing filament?

[@TheNitroFX1]

Bambulab printer always cut the filament and clean the nozzle after every print :)

[@benjaminwiedmer]

@@TheNitroFX1 not true, you have to unload first....

[@TheNitroFX1]

@@benjaminwiedmer depends. If you use the ams it always cut the filament, clean and unload

[@benjaminwiedmer]

​@@TheNitroFX1 Oooookay, thaats true 😅

[@KonradWegrzyniak]

whats the difference between swapping just the nozzle vs the complete assembly?

[@BTRusnak]

Big difference. I recently bought CHT high flow nozzle upgrade and came to this video to see how to do that. However this isn't a nozzle swap it's a complete hotend replacement video.

[@trader37]

Appreciate the simple to understand video! I just changed out the hotend based on your instructions and it was super simple!

[@amazinggaming5090]

the replacement nozzle that the printer comes with is just the nozzle. it doesn't have that rubber thing. is it necessary for the rubber cover?

[@binsuliman77]

u can detach all of the old parts from the old hotend such as the fan and the thermister and the silicon cover and attach them on the new one

[@Luceid]

lol! Excellent video! Love the anticipation and mystery. I was glued from the very beginning and got trolled at the end. SO GOOD! I'm sure that can be tweaked lol. Haha. Thanks for the laugh! Also loved the ultra high definition timelapse footage of the P1S. Always a treat to watch.

[@engineer3dprints]

😆

[@kenrodriguez9645]

So many people say screw it in tight, then heat up the nozzle to 250, let it sit and heatsoak, then tighten it again while it's hot. I've heard that multiple times, but never had to change a nozzle before. Just wondering if there's any merit to that.

[@engineer3dprints]

Thats not a bad idea. Wouldnt hurt but I doubt things would expand that much to make a difference

[@zachhalliwell553]

Pro-tip that I just discovered that wasn’t mentioned in this video but should be common sense. lol UNLOAD THE FILAMENT FIRST if you have any in there. I was so focused on doing everything in the video just right that I didn’t notice I still had filament loaded before I pulled out and the filament broke. I was able to get it out of the extruder but it’s still in the old nozzle. Thankfully I don’t need that nozzle anymore.

[@connermcgarrah2171]

All that you would have to do would be to cut the filament at the top and then reinstall the nozzle, heat it up and extrude some filament like normal. I only know this bc I did the same 😝. No need to trash a perfectly good nozzle.

[@zachhalliwell553]

@@connermcgarrah2171 lol thanks that’s what I figured and what I was going to try if I ever want to use that nozzle again. Thankfully I just purchased two hardened steel ones so I shouldn’t need it anyway, but I’m still keeping it just in case.

[@makedaevilmage]

I just changed out my clogged nozzle wit the replacement one ... but when I heated up the nozzle, it started to smoke. Scared the heck outta me and turned off the printer ... is this normal?

[@engineer3dprints]

Depends how much smoke. It’s possible there is some residue from manufacturing burning off but if its anything more than that, no it’s not normal

[@BTRusnak]

Misleading title. I came here to see how to replace the nozzle at the end of the hot end and got a video on how to swap out completely assembled hot ends.

[@Bordeminisme]

This video is missing several critical steps like turning the printer off and unloading the filament

[@engineer3dprints]

If someone is taking apart a printer while it’s turned on, they probably shouldn’t own a printer.

[@ramadandu75]

@@engineer3dprints It's my first printer, and everybody makes mistake and try to learn that's the point. The video is a step by step tutorial on how to change this part. I shouldn't be owning a printer apparently, but I tried following the video and forgetting to turn off the printer. Now idk why but the fan don't want to work. Maybe that's not related to forgetting to turn off the printer or maybe it's the issue. But damn that was a close minded answer.

[@citizen_of_world7305]

⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠@@engineer3dprintssome printers may have components which are available for hot swap and you are still missing part of unloading filament which is also crucial. You can presume whatever you want but why doing tutorials which are obviously missing vital parts. Moreover Bambu Lab is positioning as plug and play and new users friendly. So if someone is making video tutorials and missing important parts of video tutorials, they probably shouldn’t make tutorials. No hate, much love:)

[@3DJackFoster]

FANTASTIC! The link bambu sent me does not show how the hotend actually fits and does not show that the screws need to be pulled out of the hotend. I guess I should have watched the video a lot closer as the screws are missing when they pull the hotend out. My bad sorta. After much cussing I came back and searched and found your video. I was already subscribed and I definitely hit the like button. Might as well ad more to this. Got the hotend installed and now won't print with error code. Finally found out it was fan not plugged in good. Did a factory reset and then did a full calibration. Now it puts out filament but it messes up the preprint pass and drags that out to start printing. Puts down a nice first layer except for the blob that is created by dragging the preprint filament to the print area. Goes through a nice first layer except for the blob. Hits the blob and then it all goes to hell. It has done this twice now. I am thinking there needs to be some kind of Z-axis calibration like on my Prusa mini. I will have to search for such and if anyone has a link I would appreciate it. Thanks again.

[@engineer3dprints]

Awesome! Glad it helped

[@3DJackFoster]

@@engineer3dprints I got that installed and now it won't print. It gets hot and moves around but it won't print. Now it is back and forth email imatation tech support for a few days and it may run again. I don't think I will ever buy another Bambu printer. I have a Prusa Mini that has been bullet proof and wish I would have bought another larger Prusa. Thanks again for your help.

[@Dannosaurusrexx]

I changed my nozzle when I kept having a mesh/bed leveling failure but now every-time I print it won’t adhere. I did a calibration but it still does it. Any suggestions?

[@joshuakaarlela]

Hey! If you're still having trouble. Try 0000steel wool just taking the sheen off the too. Should fix problem

[@cheizaguirre5494]

U fix it ?

[@3DJackFoster]

Glue stick. I have resisted using a glue stick for over a year. Had a difficult one decided to use a glue stick and now I just glue everything it's just the whole heck of a lot easier like the cliche don't fight City Hall glue stick seems to solve the problem

Loving this channel already learned alot about my P1S. Any chanxe you could do one about periodic maintenance? Where and what to grease/lube, checking belt tension etc. Love your content :):)
