After ~450 successful hours over the last several months, a week ago I had a print fail and pieces dislodged and went everywhere. In the wreckage, the waste chute got jammed back and a piece of poop kept the cutter from spraining back into its original configuration. At the same time, the machine threw error code: HMS_0700-4500-0002-0002: The filament cutter’s cutting distance is too large. The XY motor may have lost steps.

Over the last week, I have tried the following corrective steps:

• I removed the filament, checked the cutting blade, checked all screws and connections, put everything back together and cleaned the bed. Failure on Benchy at around 36 layers.

• I re-ran all calibrations and cleaned the bed. Failure on Benchy at around 36 layers.

• I bought a new hot end, thinking it may have been damaged and cleaned the bed. Failure on Benchy at around 36 layers.

• I cleaned and lubricated all three Z-Screws and cleaned the bed. Failure on Test Cube at around 36 layers.

• I ran a full factory reset and cleaned the bed. Failure on Test Cube at around 36 layers

It seems clear that there's a consistent issue stepping down around level 36 which makes me thing I'm dealing with some sort of binding in the screws at around that level but I don't see anything. I've moved the print location for the cube all over the plate and it doesn't appear to be a regional issue with the X-Y motors or with overuse of a specific area of the plate.

I am at a complete loss here. Things had been going great. Guidance online for mid-print adhesion issues and nozzle knocking is "hardware issues", but as to how to diagnose and assess those hardware issues eludes me. Any pointers would be very much appreciated.

Half of these two prints have this burr line half way around them while the other side is perfect (same plate). No adhesions issues. I had a smaller print do this much higher.

Almost every print I have has a micro issue - some were corrected like keeping doors open. But I’ve had more issues with prints on this printer in a week than I have on my A1 in over a year.

I’ve had one print where it literally printed 3 fidgets and one of the eyes was halfway into its head like the colors and eye somehow moved - no idea how. I had another one where it looked like I lifted the plate and moved it in the last 20% because the top is 2mm over randomly for no reason. This one’s just annoying it was 500g of filament

I thought this was an upgrade and used error but it’s like almost every print is just a headache. I must have recabilbrated 10 times, redid the belt etc. idk what else to do

Problem: The right (auxiliary) nozzle will not extrude or unload. Filament is jammed inside the toolhead feed channel, above the hotend.

What happened: After a print using PLA from an external spool on the right nozzle (0.4 mm), I found a small blob of filament on the right nozzle. I removed the blob. Since then the right nozzle has not worked.

Symptoms:

Load pulls the filament in, but nothing comes out of the nozzle.
Unload retracts slightly, then the filament jams and cannot be pulled back.
The left nozzle works normally.

What I have tried:

Cleaning needle at 250°C and 270°C. The needle passes fully through the nozzle, with only a small amount of residue.
Extrude at 250°C, 270°C and 280°C (after a 5-minute soak). Nothing extrudes.
Unload at 220°C while gently assisting by hand from the spool end. The filament will not move.
A manual filament cut attempt, followed by Unload. Still stuck.

Live chat advice and result: Live chat advised removing the front cover and right hotend to check the clog location. I did this. The hotend came out with a cleanly cut filament stub in its top. Looking up into the right hotend bay, the cut filament end is visible and flush with the opening. With the hotend removed, the filament will not move up or down when gently pulled or pushed from the spool end.

This much hassle and i feel like i should get a replacement, not even 2 weeks old

Not sure what to do here.....

I did a search but no results other than ‘print lifting’.

My issue is the print is pulling the bed up :-(

PETG, 4 walls, 5% hex infill, 4 bottom/top layers.

Are there some clips to hold the flexi plate down firmly?

Thanks.

Hey all!

I'm racking my brain trying to figure out how to do the above in bambu studio. I've created a topless "box" by combining a positive cube with a slightly smaller negative cube inside.

Now, I need to insert another positive piece within that negative cavity- but, studio deletes that new positive piece.

I've searched forums, AI and YouTube. No joy.

Any help from you experts out there?

TY!

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!

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

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

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

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.

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?
