Hello, have used 3 X1Cs for close to two years along with other brands for 10 years. In all of my setups, I have my printers on very solid, stable surfaces. I had bought the anti-vibration feet for the X1C, but after testing decided they weren’t necessary. I was surprised with the movement of the H2D and the pre-installed anti-vibration feet, but after reading on the topic it seemed like it wouldn’t be an issue.
I’m printing a mass amount of recorders (musical instrument recorders) in silk PLA. Silk adds some challenges, but nothing too bad and the print itself needs a very clean bed and good adhesion. On my X1Cs, they print effortlessly. Same basic slicing settings on the H2D and they fail every time. Get about 75% done and come apart from the brim and supports as well as random layer shifts. These are printed upright as tall tubes and I’ve printed dozens on the X1Cs without a single issue, but cannot get one finished on the H2D.
I am wondering if it’s possible the feet and H2D’s movement is to blame. Everything I read said it won’t affect print quality. I don’t know how to prove it for sure, but I feel like all of the movement on a tall skinny print is the only variable that explains it.
Has anyone else experienced this or do you think I’m way off? And if I’m right, is there any option to replace with standard feet like the X1Cs?
I don’t have much to add other than I was also trying to print a musical instrument (tin whistle) on the H2D and wanted to use the H2D over the X1C because I could print it in one piece with the extra height. I just couldn’t get it to reliably complete the print. I put the project on hold hoping that changes to the slicer might fix the problem but never considered that it might be the feet. Mine was getting knocked over during a color transition but maybe it could have been weakened by the movement due to the feet.
Thanks. I’m trying to print about 100 of the recorders in the link below. I’ve wasted 2 rolls of filament now and have literally sat and watched over and over. Perfectly clean bed. Same slicer settings that work on the x1c. I bumped up the support and brim and not matter what, once it reaches a height where the center of gravity is raised, it detaches or layer shifts. I’m totally convinced it’s the feet, but don’t know what to do about it. Wish Bambu gave the option like they did with the x1c. I see no advantage for my setup and only the potential for issues. https://makerworld.com/models/1212604
Why kind of build plate do you have on your X1 Vs the H2D? Are they different? Have you tried uping the bed temperature to 70 for better adhesion?
I know you said it printed perfect on your X1 so I’m trying to find where differences may be. I looked at the model and other people were having difficulty printing it too.
For what it’s worth, I tried taking the oem feet off the H2D and putting 70 duro sorbothane pads in their place in an attempt to lessen the wobble. Bad idea lol.
Instead of there being less motion, there was the same exact amount of wobble except now my decently sturdy table started shaking around with the H2D.
I immediately put the oem feet back on. Unless you have a base or table that’s 100% solid and mounted, I would advise against trying to replace the feet.
I’m surprised those are coming loose. There is a tremendous amount of support on them. The amount of support on my whistle model is tiny by comparison. Is it the filament? Silk filament always seems to be trying to sabotage the print in some way. Since you are printing it on the H2D, you could try printing the support material in a basic PLA and the model in the silk.
They’re the same. Textured PEI. And yes I did some temp tests since it was silk. The thing is, the adhesion is never lost which leads me to think it’s the motion. The brim and supports stay stuck on the plate and either the model detaches from supports or there’s a massive layer shift. And yes I saw all the difficulties, but it seemed like they were more from dirty build plates. Mine is perfectly clean like 5 times over and goes well on X1Cs, but fails on every h2d print.
Yeah I had printed a few on my X1Cs that I have at work in both regular and silk. 0 issues and it seemed like an easy print. Then my H2D at home can’t get through one successfully. I want them in silk but tested regular Bambu basic and nothing will fully finish.
Interesting. I was considering swapping out the X1C feet, but don’t know how interchangeable they are. My base is pretty impossible to wobble, but I don’t want the printer to possibly walk itself off. Just doesn’t make sense to me why Bambu put standard on the x1c with the option for anti vibration and only has anti vibration as an option for the h2d. Unless I’m severely mistaken I have a hard time believing it has no effect on any type of print.
I installed some TPU 95 feet on my H2D yesterday that I printed from maker world. HUGE difference. The machine is 10x better and I can’t tell a difference on my prints. With Arachne the prints still look great.
The fact that the printer shakes should have no impact on print quality, as the printer operates within its own reference system.
I tested this by isolating the printer from external vibrations, and there was no measurable difference in print quality—either better or worse. However, these tests were performed using an old, reliable Prusa MK3S, not a Bambu Lab printer.
People have tested the Bambu mini printing hanging from the ceiling which was impressive. So it’s hard to believe that the feet would be an issue but I don’t know there are people in that Makerworld post that believe changing the feet to tpu improved prints. I would think Bambu tested the feet situation to a good extent.
This doesn’t explain why it prints fine on the X1C vs the H2D but I was looking very closely at where the supports touch the model and they don’t seem to be supporting anything. The supports wrap around the model but then when you get to the top of the supports, there is nothing above it. The exception to this is the mouthpiece. That part does use and need the support. I don’t think the supports are doing much if anything everywhere else. I think the thing that it holding it is at the very bottom. You could try experimenting with adding a raft to it.
I just used some old Inland TPU 95 i had. I tried it just because I can’t stand how bad it was shaking. When I say it was a huge Improvement I’m not saying improvement on print quality but just on the amount of shaking. Print quality looks identical to me
I think this is a bug in the current version of Bambu Studio. I was printing something the other day and noticed the exact same issue where the tree supports were not supporting the items properly, there were a few layers missing from the support interface. If possible try to use regular supports instead of tree, or maybe reorient the object, thats how I fixed my print.
The H2D shakes and moves alooooot more than the x1c. They probably didn’t want people’s rickety tables wiggling apart and then them complaining that their printer crashed to the ground lol. That would be my guess why they put the anti vibe feet on it as standard. I use 50 duro sorbothane pads for my x1-c’s with good results.
