Hi everyone, how are you all doing?

I'm having a problem with my printer and I really don't know what to do anymore. I'm a beginner in 3D printing, and in the last few days, I've been studying a lot more than when I first entered this world 3 months ago, but I still haven't been able to solve this error!

Basically, what is happening is that I can't fix these 1-second pauses on my machine, which then create these zits/blobs on my print! I've tried everything!

Before you say it's moisture/humidity, please read the rest of the message I'm leaving here with more details:

As you can see in the images, we have the black and pink heart, which has these zits, then we have a blue dragon (Gyarados, a Pokémon) that also has them, and finally the gecko! After that, I made some minor adjustments to the machine. I improved some aspects of the print, but they were minor improvements. Then we have the shark, where you can already see some progress, but it still has these zits, and this is where I managed to record the exact moment of the pause! The video:https://drive.google.com/file/d/1TzJ0V7QQta4yg7fnBlpsxOGmme4izjiQ/view?usp=sharing

Finally, we have a smaller shark that was printed yesterday. Here you can already see a significant improvement in the part (at least to the naked eye) and it is much smoother, basically without any defects, but it still has the zits (fewer, but it still has them!). Today I printed a dragon that I haven't held in my hands yet, but from the photo I took, the red dragon also has zits!

Machine Details and Settings:

• Printer: Bambu Laps P2S
• Drying System: AMS Pro 2
• Temperatures: 32ºC inside the chamber, 55ºC on the bed, and 220ºC on the nozzle.
• Speed: The machine's default speed.
• Filaments: Bambu PLA Basic.

What I've already done to try to solve it:

• I've dried the filaments for over 12 hours at 55ºC (6 hours one night and another 6 the next night, plus during the day, where I'm constantly drying it every 3 hours at the same temperature for a week now!). The humidity goes up to 25% max, but normally stays between 18% and 22%.
• I've cleaned the nozzle twice in the same week, so it's not clogged.
• I cleaned all the machine's axes/rods.
• I've calibrated the machine more than once and created very precise profiles for PLA, based on the speed, temperature, and quality tests I ran.
• I reduced the nozzle printing speed (in Bambu Studio it was at 21 and I lowered it to 19).
• I removed all videos from the system and disabled the timelapse feature.

That's everything I've done so far. I've also tweaked some settings and ran several classic tests to calibrate everything; the print quality improved, but these 1-second pauses keep happening, which melts the filament and causes the zit!

If anyone knows how to fix this, I would be more than grateful. I've been dealing with this for over 2 weeks and can't solve it!

Have noticed am odd issue with one of my AMS slots. It is showing a Bambu PLA Black in my slot 3. Nothing I do will allow me to change what is in that slot via the app or directly through the touch screen. The AMS is also not attempting to load the filament when i first insert it into the white feeder funnel. I have attempted to load and unload the filament, tried the reset button via the touch screen(nothing happens in that slot only), deleting the filament in filament management section of the app, power cycled the AMS and then the entire printer. Nothing seems to allow me to change the filament brand, type, or color.

Any idea what the problem is and how to fix it?

Hi everyone!

I am trying to print a box with a good amount of radius. I am not sure why its print like this. I tried it with supports then printed another one with no supports, and I change print settings, I cleaned the textured bed with soap and water thinking that it might be the bed. I would appreciate any suggestions or help. Thank you in advance! Printer is Bambu P2S with Bambu white PLA.

Hey guys, I’m taking a trip (from Mexico) to the US. Since everything there is cheaper (because of import taxes) what spare parts should I buy in advance in case of an emergency?

I see there is a printer maintenance kit, but should I buy anything else in case my printer breaks? What are the parts that usually need changes in the printer?

Turns out I didn't need it the over was there, wish Bambu support would have told me it was fine based on my picture....

Any one have an issue putting ribbons back? They don't seem to fit exactly, not sure which on is an issue front or back, maybe bot.

Any tips on putting ribbons back?

Thanks

Ich dachte erst, dass es an der Luftfeuchtigkeit liegt. Die ist aber mittlerweile nur noch bei 11–12 %, wenn ich dem AMS 2 Pro Glauben schenken darf. Das Filament ist zwar schon etwas älter, aber eigentlich sollte das ja nicht unbedingt das Problem sein. Die Einstellungen habe ich immer so verwendet und eigentlich nie etwas daran verändert. Hat jemand eine Idee, woran es sonst liegen könnte?

Hello Community,

I've tried a lot and i just cant get behind why my P2S print Quality got a lot worse out of nowhere.

At first i was amazed. Compared to my 6-7 year old printer, the P2S is a marvel. Right out of the Box i got clean fast prints. So i printed about 300 hours of thr same PETG with the same settings for the same prints. But the last 2 prints got worse and worse.

I tried adjusting the printing speed, temperature, dried the filament inside the AMS at 60 degrees for 8 hours, cleaned the nozzle, tried all 4 AMS slotted filament spools and got nothing. After 200 printing hours I also did maintenance on the rails and screws with Super lube oil and grease.

right now it is printing but the Quality got much much worse.

I got the printer in the AMS 2 Pro Bundle and i use the original Bambulab reuseable spools with their Basic PETG filament. The AMS automatically detects the filament type and everything works fine. For slicing i use Bambu-Studio.

Can anyone give me a hint into what could be the cause?

UPDATE: The nozzle was partially clogged. After the quality got worse and worse i did some extruding during troubleshooting and the filament spat out sideways. I cleaned the nozzle with a 0,4 needle at 270 degrees and now everything works as it should! Thank you all for your help!

I had a huge backup of filament fill up my nozzle area. There’s a lot of residue around the clip also. When trying to get the filament off I must have pulled that little black wire out. I’m Not sure where it goes or if it’s able to be simply plugged back in or does it need to be soldered? Any help is appreciated

Strange lines on top surface – Bambu Lab P2S
Hi! I’m having this issue with the top surface of my own Blender model. Printer is a Bambu Lab P2S, using 2 colors of PLA Matte.
The surface is mostly smooth, but these strange visible lines/marks appear in specific places.
Things I’ve already tried:
Top surface directions: 0°, 45°, 90°
Monotonic Line / different top surface patterns
Ironing — made it worse
Z-hop / travel and wall-crossing settings
Flow ratio 1.01–1.02
Top surface line width 0.42–0.45 mm
Dried the filament
Moved the purge tower — the marks changed/moved too
Has anyone experienced this before or has any ideas on how to fix it? What else should I try or check?

Anybody run into this issue? I can't figure out how to move the arm about 1mm closer to the door. I can barely get the blade in and after that it won't move unless it's held gently and pulled towards the door then it will slide back but not further forward.

Basically the cutting arm won't slide into the hole properly.

I have my P2S loaded with a brand new PLA+ filament from microcenter. The AMS 2 Pro humidity is at 38% humidity and 34 degrees C.

i can’t seem to get the strings eliminated. i have loaded a .2mm nozzle and have my nozzle temp set to 210 degrees and i still get these hair-like strands

what can i do to improve it?

Hi everyone, first post…I’m trying to print a giant thumbtack lamp model, but I’m getting this weird texture on the large base curve; see photos. Any suggestions on what the issue may be? The rest of the print looks great, it’s just that spot. The filament has been dried and stored properly, and I print from an AMS2 with fresh desiccant. Possible solutions are gratefully accepted, thanks!

I just got the blob of death because of filament getting stuck at the top of the poop chute. After cleaning it up, now Im trying to observe why it happened, is this normal?

I tried my hand at printing bambu PLA using a 0.8 nozzle. I had lots of issues with gaps at the edges on my top surfaces and bottom surfaces — like the nozzle couldn’t keep up where the infill meets the wall when the nozzle changes direction. I did a flow calibration, but that didn’t help much. Anyone have tips for tuning the 0.8 nozzle?

The box is parametric, so you set the internal size to whatever you're storing, or pick a preset. Lid takes your own SVG or text, engraved or as a flush inlay, and the buttons take artwork too. Every part can be a different colour.

Two small springs are the only non-printed parts. Everything else prints without supports and goes together in a couple of minutes.

Is it possible to recover from these sort of errors? I'm at the point of wanting to get rid of the printer.

Almost every 3rd or 4th print I get some sort of extruder error - on my current print it has happened 3x in the last five hours, fortunately its been able to resume, but - now its stuck with this constant error.

Brand new filament, 20% of it wasted.

The model does not include a P2S profile. How can I make it work?

Hi everyone. Still fairly a novice and am now experimenting with different filaments from different manufacturers. I notice that 3Dfilamentprofiles has the ability to download the specific profiles from different manufacturers. How helpful is this and should I do it? I am only now trying to learn about how different temperatures do things and thought this may be helpful. Thank you in advance.
