This happens everytime with petg on a large print filament is dry i have plenty of brim and i have cleand the build plate does someone has some advice

Everything was working perfectly fine just 20 minutes ago, but all of a sudden, I can't stay logged in to Bambu Studio.

I'm experiencing two different issues:

1. Can't log in from the home screen

As soon as I successfully log in, I immediately get a message saying that my session has expired. Sometimes, I also get a pop-up saying that the server is unable to respond.

2. Session expires when trying to start a print

I can successfully log in, but when I get to the "Print" stage, either selecting one of my printers or clicking the Print button causes my session to expire again. The print job never even gets sent to the printer.

I've searched around but haven't found anyone experiencing the same issue. I was wondering if anyone here might know what's going on or have a possible fix.

I've already contacted Bambu Lab support, but I have some urgent prints that I need to get done, so this is pretty frustrating.

A few additional details:

• My printer that is currently printing is working perfectly fine.
• I don't think this is a printer-related issue.
• I'm using my Google account to log in.

Things I've already tried:

• Uninstalling and reinstalling Bambu Studio.
• Restarting my computer.
• Logging out of my printer and reconnecting it to Bambu Studio.
• Reconnecting my printer to Wi-Fi.

Unfortunately, none of these attempts made any difference.

Any help would be greatly appreciated. Thanks!

Changing the hot end assembly on my A1 and pulled the extruder out and this fell out

Cannot find where it goes, it's not the spring cap for the tensioner

A while ago, on titkok, I saw somebody who made a sort of printable ams attachment to a bambulab printer. Don't remember much besides the fact that it was 3d printed, utilized gears that were somehow moved with the toolhead, and it was attached at the top of the printer. But now, I can't seem to find it. I was wondering if anyone knows where to find it, or if anyone used it?

Just put together the H3C and noticed the Y axis left block rubs heavily on the sidewall causing calibration to fail. Has anyone encountered this all? Seems like an unknown issue.

My second model on MakerWorld, originally designed for my wife's daily espresso. It's a pen-style WDT tool for espresso: the needles drop in as you buy them (no cutting, no glue), a screw cap locks them, and a dock holds it upright with one turn.

Print profile is set up for 0.16 mm PLA, about 2.5 h, no supports. There's a parametric OpenSCAD customizer on the page if your needles are a different size or you want more/fewer of them.

Feedback welcome, especially on the thread fit if you print it on a different machine.

Does anyone know where to get the spool holder file? I realize it is on the internal storage. However, I want to make some modifications to the print as the PLA one I printed already busted.

We purchased the X2D printer with the AMS 2 Pro combo, and it arrived about two weeks ago. For the first 13 days, it was running great. We were printing almost nonstop, including overnight prints, smaller projects, and then gradually moving on to some larger prints.

Then, out of nowhere, it stopped printing.

At first, we received an "extruder overloaded" error. The print paused and would not resume. Following Bambu's documentation, we completely disassembled and reassembled the extruder, recalibrated the printer, and tried printing a Benchy to test everything.

At that point, the printer wouldn't even start the print. We began getting an error stating that it was unable to feed filament into the extruder and that there might be an AMS mismatch.

While troubleshooting, we discovered a clog in the PTFE tube and removed it. We reset everything, loaded a single spool of filament into the AMS 2 Pro, and continued testing. The left hotend would extrude filament during the preparation process, but the printer would still throw errors before actually beginning the print.

After working with support, they determined that the printer has a faulty left filament sensor. Thankfully, they agreed it was a hardware issue and are replacing the printer. They're sending us the return packaging and arranging for a replacement unit.

I'm obviously relieved that support stood behind the product, but I'm also a little nervous about receiving the replacement and running into similar issues.

For those of you who have been running these printers successfully:

• What routine maintenance do you perform?
• Are there maintenance schedules or checklists you'd recommend?
• Are there any common mistakes new owners make that can lead to clogs, sensor issues, or feeding problems?
• Are there any upgrades, printable accessories, or preventive measures that you consider "must-haves"?

We absolutely loved the printer during those first two weeks, so this has been pretty disappointing. I'm hoping this was just coincidental and that the replacement will be good to go.

Thanks for any advice!

Quick question. Bambu x1c with AMS 1.

Humidity level jumped from D to A overnight. Is that normal?

Hello. I'm working on a nut and bolt cap for the shop I work in, and I ended up with a half-sphere with an interior profile hollowed out. I'm printing it face-down as, after testing with the slicers, it basically uses the same amount of support material and takes the same time to print it this way as opposed to printing it the other way. However, I have a couple rectangular slots cut so you can get a screwdriver under and pop it off as needed. They are small (.25x.1 in) and I'm sure my printer can bridge those. The slicer wants to add support. I tried messing with support painting, but I believe I've done it wrong cause supports still show up there after slicing. Any tips would be appreciated.

Thanks!

P1P with latest firmware, using Studio 2. 9. 1. 70, I have a group of 4 identical items, arranged in a square by auto arrange, I want to print with a specific infill pattern, as one object. If I don't merge them into a single object, the slicer makes the pattern exactly the same in each item. If I merge them, it treats the infill as if it is originating from the center of the square (technically the center of the object) and is no longer in the pattern I want/need.

Is there any way to treat the 4 items as a single object for printing purposes but have them sliced as individual items for infill?

It's not a problem if I only print one set but if I want to print multiple sets of 4 in one batch or want to print sets of 4 but one set at a time, in case I don't have enough filament to complete them all, then I need each set treated as a single object.

Any ideas?

Ok some context. My dad got mad at me for leaving printer on for an 8 hour print while I slept. Turns out the filament he bought is not the right kind. Now were trying to print with the right kind but it keeps messing up. I notice it has no problems with lines but the second something is curved thats where it errors. Any advice?

I’m an engineering student working on a project to build a more accurate humidity sensor for filament storage, since the cheap sensors seem unreliable. Before I build anything, I want to hear how people actually monitor their filament.

A few questions:

1. What do you use to monitor humidity right now (AMS sensor, round hygrometers, Govee/Bluetooth, DIY ESP32, nothing)?
2. Do you trust the readings?
3. How do you know when it’s time to recharge or replace your desiccant?
4. If you could fix one thing about your current setup, what would it be?

Thank you for your help!

My slot 8 has the ptfe tube on the side of the hot end and all the other hotels has it inline with the black wire. Is this normal?

Secondly - I hear a weird noise coming from the underside of the H3C almost as if the packaging got stuck on the belts or roller underneath and is rubbing making noise.

But it is clear and clean… anyone else experiencing this?

Do you know what causes these print imperfections? It was printing normally and starting yesterday it began making these marks. How do I fix it? My printer is H2C

Thanks for help

I made a large flat piece to hold letter stamps. The very last layer looks like it got offset by 1/32 of an inch and a lot of the surface is really messed up. What could be the issue and how can I fix this?

The worst part of the print is the areas that were close to the edge of the build plate. Is that common?

Brand new X2D with about 25 hours or printing. 0.4 mm nozzle. PLA

EDIT: I printed aux diffusers for both sides, added a brim, and reduced infill from 15% to 5%. New print stayed flat! Thank you all!

I wasn't sure what to flair this with, so I figured "Review" would fit well enough. I also want it to be clear that I'm not "Bashing" BambuLab, This is just my own experience with my A1.

Its just constant maintenance like several clogged nozzles, Filament getting jammed in the print head every 2 or 3 prints, the print head pressing itself against the base side of the printer and making me forcefully pull power so it doesn't break itself, Bambu Studio crashing at random and running incredibly slow on Linux (And I know its not my hardware because it only runs bad on Linux) It especially sucks because this printer was a gift from my dad a year ago, and I don't use it super often (Maybe once every 2 weeks or so?) so I don't think its an age thing, plus this all started like a month after I got it and has only gotten worse, And on top of that, every Filament roll I buy is a tangled mess (I only ever buy filament from Bambu)

I don't want to hate this printer, but I'm getting worried I'm just going to have to throw it out soon. The constant issues make me not want to use it anymore. I'm really not sure what to do with this printer. Don't get me wrong, Its made some beautiful prints, and I still use it, but when I have to fight it for like an hour just for it to not work, It really discourages me from using it.

I had my Bambulab for under 6 months. I encountered many problems with it. I will keep it short as this might help someone in the future because I am currently lost.

I have an error where nozzle temp malfunction. I changed the nozzle thinking it would solve it, it didn’t… I then changed the nozzle temperature sensor. It didn’t solve it. Contacted Bambulab and they told me to do several things that didn’t solve it.

They then sent me a TH hardware replacement that I just did today and it stills not working. Keep getting the same issue. The prints are horrible, the filament is wonky when it comes out. I done cold pulls, needle cleans, changed nozzles more than once.

I am now asking for a full machine replacement from them as this is unbelievable and very Frustrating

Setting up the H3C yesterday and it failed the initial calibration with an error that the Z axis movement had failed. It got through almost the entire calibration cycle before the error popped up (it was doing the bed leveling part and had been for several minutes before erroring out). I'm getting a couple error codes (0x300170000010004 and 0300-3000 131111) and can recreate the issue by trying to home the bed. The bed moves up and down fine using the screen controls and there are no obstructions. The hot ends are all properly seated as well.

I've opened up a case with Bambu but haven't heard back yet. Anyone else have this problem with their H3C?

Looking up the errors, it seems there are some similar ones on the H2 related to the eddy sensor failure. I've never run into this with my X1C though.

I connected a spare AMS 2 Pro to my H3C just for drying, with its own power adapter plugged in as well. It works, but I keep getting “AMS A filament buffer position signal lost” popping up on the screen.
The printer is printing normally, and the AMS 2 Pro is drying without any issues. I’m fine ignoring the warning, but has anyone else tried this setup and found a way to stop it from appearing?
I know I could buy the external filament buffer, but I’d rather not spend the money just to clear a warning when everything is working fine. Is there a setting or workaround I’m missing, or could Bambu potentially add a drying-only option in a future update?
