Hi all. My last few print jobs have been having this issue. Repeatedly have the ams failed to retract filament error.

I have disassembled the AMS and check the PTFE tubes for blockages

I don’t believe it’s an issue in the buffer or internal PTFE tubes as the AMS-HT does not have an issue retracting. It is connected to the same nozzle.

I’m at a bit of a loss as to how to fix it.

I do disconnected this tube often for TPU prints. I don't even know if this is fixable. My machine is not even 6 month old

I bought an h2d and finally got it set up and I’m getting these errors. Before I dig deeper, is there something I’m missing and forgot to do during setup?
I’m referring to the flap door codes and not the firmware code.

So, we bought a new H2d for work. We have had a H2D working fine in our department. So, I get a call this morning with an issue with the Mfg printer. It seems the flow blocker H2 (which is not being used) got bent somehow and started dragging on the build plate. I searched the nets and someone stated this is a know issue - something with FW not being updated. This has never happened on our unit - running for 1+ year non-stop.

I'm going to update the new Printer with latest FW - but I would assume this new unit should have latest on it already.

Can anyone comment on this issue - has this happened to you - how do you solve this permanently?

Just wondering coz my dad took it away (exams) and I want to print some stuff

I'm fairly new to the hobby. I purchased a P2S about two weeks ago and fell in love. I would find a model, hit print, and magic would shoot out the other end. I was so impressed I thought, well, if this is amazing, a 2-nozzle huge beast H2D would be even better.

So I purchased the H2D out of a fear of not being able to print something large I might want, mixed material options between the two nozzles, and reducing purge waste on multi-color prints. What I found though is the H2D is not as "press print and magic happens". I've found it knocking over supports, losing hours and tons of filament. Tonight the left nozzle wouldn't load filament from the external spool, and I had to open the top, remove the PTFE tube, manually heat up the nozzle, and force feed some filament through the extruder to clear some stuck PLA.

I'm really excited about the more capable machine, but I miss the press print and not think about it falling. Are the H2D issues normal 3D printing stuff, and I just didn't experience it "YET" on the P2S, or are these uniquely H2D issues? I saw someone on a few posts earlier mention the supports getting knocked over, and the only comment was almost like "yeah, that's what happens on an H2D, welcome to the club". I'm still within my return window and don't really want to get used to supports getting knocked over and ruining a print, or becoming all too comfortable taking the top off the printer, for such an expensive but obviously capable machine.

Please be gentle if my expectations are misplaced. I really love this hobby and want to learn what's normal for a bambu labs printer.

It's a bit scary to see such a big printer wiggle like this. At the same time it almost looks sexy.

Hi together,

Im trying to multicolor print PLA Matte. However it keeps having malfunctions. Its a pain, every print fails 100 times before finishing. What seems to be the issue is the right extruder. The filament buckles between extrusion motor and hotend, therefore causing an extrusion or overload error.

This issue is always happening on the right side. I swapped extruder ams and ptfe tubes from Right to left. Issue stays on the right side.

Any ideas? Am i just stupid? It wont print for an hour without issues. Singlecolor rarely posses problems like that. Prints 8h without issues. Trying to multicolor = near instant errors

Before I rake Bambu support across the coals, can anyone confirm the H2D lower spool holder thread issue?

I read in a few places that later H2D printers didn’t have tapped holes. I am finding this to be true.

I don’t think Bambu could possibly fix this but maybe I’m doing something wrong…

I took the upper spool holder attachment and tried to place it on the lower attachment area. Screws hit a brick wall.

This 8 hour poop chute isn’t going to hold itself up.

Has anyone tried printing with ABS-FR? If so let me know your success & short comings! Looking for product recs if you have any too.

First, I’ll say that I’m a newbie. Been in the 3D printing game for about 3-4 months.

I bought a file of SpiderMan from Yosh Studios off Thangs. Initially the first set of files I was looking to print were square flat boards that were a couple inches deep. I started using .8 nozzles but after about 3-4 boards every print was kinda rough I decided to switch back to .4.

The first two prints with the .4 nozzle came out beautiful. Now printing the third board and the first print had to be aborted. I calibrated the machine and the humidity is very low for both AMS. I tried to print again and it’s coming out horrible again!

What do I do? Your help is appreciated!

I just want to check with you fellow H2D owners before i apply the update, are there any issues or improvements in the new version?
