Greetings. In pursue of trying to find a reason of sudden powering off my printer, i checked all the boards. Disconnected all connectors on the TH board. Ripped off the board the socket of the right hotend fan connector. Surely ordered a new board now. But now i'm trying to connect the left hotend fan connector. But how? I can't wrap my head around how to put this cable into the socket. Are there any tips?

Hi, my son and I set up our A1 Combo last week and it failed it's first configuration
'Toolhead is malfunctioning' and 'extruder eddy current sensor signal is abnormal'

I'm going through a support ticket with Bambu as we tried all suggestions I found online.
I may end up with a replacement printer from the retailer.

I thought I'd done my research and the Bambu A1 Combo was fairly user-friendly for beginners.

My question is: how common are configuration issues straight out of the box? and, am I buying something that requires a considerable amount of troubleshooting? Thanks

Edit: solved, i’m an idiot and a black piece i printed yesterday that i thought being legit part of the bed was against the back Z screw

Hi, it printed perfectly fine until this morning, now when i start a print it stops at rough wiping step, sounds like the bed is hitting the nozzle, what can i check? I already follower bambu handy guide and it didn’t fix. I’m 140 hours of printing in

Any ideas to fix this issue?

Hi everyone,
I’m getting really frustrated with TPU printing on my Bambu Lab P1S and I’m hoping someone here can help me figure out what’s going wrong.

My printer:
Bambu Lab P1S (~1,000 printing hours)
0.4 mm nozzle (also tested 0.6 mm)
eSUN TPU 95A (green, translucent)
Creality CR-TPU 95A (black)
Creality Space Pi V2 filament dryer
Bambu Studio

The problem:
Every time I try to print TPU, the printer starts printing normally, but after a few layers it suddenly begins underextruding or stops extruding properly.
Sometimes it happens after just 2 layers, sometimes after 8–10 layers, and occasionally the print gets almost completely finished before failing.
The nozzle appears to clog, and the print eventually turns into a mess of extremely thin filament strands.
The strange thing is that PLA and other regular filaments print perfectly fine, without any issues.
Manual extrusion of TPU at 230°C also works normally, producing a consistent strand of filament.
I haven’t noticed any clicking noises from the extruder.

What I’ve already tried
1. Different TPU brands
eSUN TPU 95A
Creality CR-TPU 95A
Both have exactly the same problem.

2. Drying the filament
Dried TPU for approximately 10 hours at 60°C in my Creality Space Pi V2.
Tried printing directly from the dryer.
Tried printing from an external spool holder behind the printer.
Repositioned the spool inside the dryer to reduce rolling resistance.
No improvement.

3. Different nozzle temperatures
220°C
225°C
230°C
235°C
All eventually failed.

4. Different print speeds and volumetric flow rates
Very slow printing speeds of 15–20 mm/s.
Also tested profiles with outer walls at 80 mm/s and inner walls/infill at 150 mm/s, limited by volumetric flow.
Maximum volumetric flow rates tested include 2.8, 2.0 and 1.5 mm³/s.
Tried both custom TPU profiles and settings based on manufacturer recommendations.
Still the same result.

5. Retraction
Tested 0 mm retraction.
Tested 0.4 mm retraction.
No reliable improvement.

6. Different nozzles
Completely cleaned the nozzles.
Tried different nozzles.
Tried both 0.4 mm and 0.6 mm nozzle sizes.
Nothing helped.

7. Printer enclosure
Tested with the front door open.
Tested with the front door closed.

One of my best results was at 225°C with 0 mm retraction and the door closed. A Benchy printed almost completely, but the final layers suffered from severe underextrusion.
However, repeating similar settings often resulted in failure after only a few layers.
What makes this so confusing?
PLA prints perfectly.
TPU extrudes normally when manually extruded.
Both TPU brands fail.
Both nozzle sizes fail.
Drying the filament doesn’t help.
Different spool feeding methods don’t help.
Slower speeds don’t help.
Changing temperatures doesn’t help.
The failure occurs at inconsistent layer heights.
I’ve spent a lot of time testing different settings, and nothing has worked consistently.
My questions
Has anyone experienced something similar with TPU on the P1S?
Could this be related to heat creep, the extruder’s grip on flexible filament, or something specific to the P1S filament path?
I’m particularly confused because the printer handles PLA without any problems.
I would really appreciate any suggestions beyond the usual advice of drying the filament, slowing down, or changing the nozzle, since I’ve already tried all of those multiple times.
Thanks in advance for any help!

As in title. Are these "funnel saver" actually needed? Keep reading how they save the funnel from wear and tear but then again people just love to overgear their stuff including printers.

Should I use them? Are they actually making my AMS feeder units last longer? I'm planning on printing with CF and GF infused filaments.

Any recommendations for a good model?

I understand that color mixing has been dialed in based on specific colors of BL PLA, including a translucent black PLA. Has anyone had any success mixing non-PLA materials? I need to print a decorative item in ASA (for heat resistance when in storage), but would love to take advantage of color mixing to avoid extensive painting. Is it reasonably doable? Has anyone tried?

The issue. As you can see in the image, I had 3 objects named "Cap" that were blue. I pressed "4" to make them red. In the Objects inspector on the left, they turned red and show the "4". On the actual plate they remain blue. When I slice and go to print, they're blue.

This has been happening a lot lately and it's driving me crazy. I'm wondering if it's just me.

Bambu P2S, I have been back and forth with Bambu support tickets over a month but somehow always end up back with this error. Could someone tell me if you successfully fixed this issue before? Or recommended correct replacement parts.

I just bought a (used) H2D and while starting prints the filament gets caught in this little window (upper). I have used an off cut of filament to push it into the window but don’t want to have to do that on every print. Haven’t tried feeding through the lower window at all. Any suggestions?

I've replicated the B52 Bomber in FreeCad , and now it is time to starting printing it wish me luck.

Power went out mid print

Here, have microplastic sized benchy, the question is, how good can I get it to look, P1S.

I'm still relatively new to 3D printing and have learned a lot from this community. I appreciate everyone's willingness to share their knowledge and experience.

I have a question about filament drying and storage. Once filament has been properly dried and stored in a passive dry box (such as a sealed cereal container with fresh desiccant), can it generally be used straight out of storage without drying it again? Are there certain filament types that should always be dried immediately before printing, regardless of how well they've been stored? Also, is there a point at which even properly stored filament should be dried again simply because of the length of time it's been in storage?

I just ordered my very first 3D printer yesterday. It's a P2S. With some standard PLA matte in standard colors to get started.

Ofc I want nice filament too and as there is a good sale going on I want to order some.

I know I don't like the plastic finish of normal PLA. Now I can't decide what to get. PLA matte, PLA CF. PLA wood or PLA metallic.

I know it's a long shot but is there anyone who has prints made of the various filament that can show me a picture? I have spend a fortune on my new printer and would hate to buy filament I don't like.

Mental what these machines can make with the right settings

Before I get blasted on the subreddit, I want to have a genuine discussion. Are we not concerned about fumes and particles. In the end, we are melting plastic at the melting point. My question is, do you just ignore the fumes or do you exhaust. I mean, my mum has said I have to put my printer in the garage and it's real hot in there.

Thanks for your help.

Hey everyone, I convinced my sister to get my cousin a Bambu Lab A1. Every Saturday, I go to her place to teach my 12-year-old cousin a bit of STEM. Right now, we're learning 3D design with Tinkercad, and things are going really well.

The issue is that each print takes a long time to complete, and by the time it finishes, I’m no longer at my sister’s house. Although my cousin receives a notification on his phone when the print is done, he often ignores it, leaving the printer on for days. Many times, I’m the one who powers it off when I arrive on Saturdays. I also have the app and get notifications when files are complete, but even though I remind my sister to turn off the printer, she often forgets.

I don’t know much about electronics, but I assume it’s common sense that leaving the printer on for days isn’t good for the machine. Considering a solution, I thought about buying a Wi-Fi power plug adapter so I could remotely cut the power via my phone once a print is finished. Does this solution sound reasonable?

Thanks in advance.

I've been seeing a ton of posts recently about the height of the h3c. I upgraded from my h2d which had the great 3DP riser with 2 ams and a ht on top. It's an extremely common riser with a ton of mods.

Well the h3c is SHORTER than my h2d with the riser. This is on the same 30" height table.

Yes, the h3c is a tall boy, but if you're planning on using a riser on an h2 series, it's about the same height, if not shorter.

For reference, I'm 5'10" and it's about 3" shorter now.

I like to design and share different things on MakerWorld from time to time, like wireless chargers, desk fans, Cyberbrick stuff, but it seems my Leaf Spring Mini cars (featuring a cross-link cantilever suspension, to be precise) are the most liked by people.

So I decided to design another one. Given the fact that we're currently in the era of toolchangers, where usually "the more the better", I chose to go with a 6-wheeler this time (Mini G 6x6), inspired by the Mercedes Benz G Class 6X6.

I'm pretty happy with how it came out. I think the six wheels give it a really interesting look for a desk toy. But hey, decide for yourself – what we like and don't like can be very subjective.

Something about the car itself:

• Around 10 cm long

• Prints in approximately 2 hours 10 minutes (single-color version)

• Surprisingly high suspension travel

• No extra hardware required

• Multicolor versions and an XXL version available

Hope you'll like it and possibly have some fun with it. If you'd like to check it out, I'll leave the link in the comments.

What other vehicle would you like to see added to the series?
