  • Make sure you didn’t accidentally turn “E in mm^3” on in the settings (if it’s stock firmware) – no fucking clue why they allowed that setting to stay on that machine; as it was from a time when switching from the 3mm standard to 1.75mm standard.

    Also, never listen to anyone who tells you to start adjusting E-steps to fix a flow problem. They mean well, but they clearly don’t have enough experience to understand when or why you’d want to change that. E-Steps is a calculated value from the manufacturer based on known dimensions. If something is wrong hardware-wise, you fix THAT instead. E-Step adjustment was for the old days when you were making your own hobbed bolts by running a tap along the edge of a bolt and every bolt you made came out with a different effective diameter. Manufacturers know the exact diameter of their drive gears, and thus know the correct estep value and you don’t need to change it.

    sniped down the bowing tube and made sure it was flush with the nozzle.

    The fact that you said you snipped the bowden tube worries me; you’ve gotta cut it with a blade. Flush cutters do not leave it flat enough at the bottom and you’ve likely just caused yourself more issue. Either use a PTFE cutter designed for it, or a razor blade of some sort (Xacto knife, paint scraper blade, etc)

    https://www.youtube.com/watch?v=uKN0VOuul0o – This video is quite possibly one of the best videos on the subject matter. Take 14 minutes out of your life and read it and commit the knowledge to memory; especially if you own an older Ender 3.

    You can also disconnect your PTFE tubing from the extruder side of the equation, heat up your hot end, and try to extrude 100mm of filament, while trying to hold back the filament from the extruder – It should be pretty strong, if it slips too easily, you can narrow down your issue to the extruder. If it’s strong, but it’s tearing the filament apart when you try and print - then the issue will be down at the hot end. (Or possibly misconfigured slicer setting, like you’ve set your layer height to 3.0mm instead of 0.3mm for example) You want to divide and conquer here. Test the pieces separately, then fix the actual issue.

    Additionally, Touch probes don’t fix leveling issues. If the machine isn’t printing fine before you add a touch probe, they won’t magically make things work - all they do is automate the process for an already perfectly-functioning machine. They can also correct for non-linear malformations, but they are not there to fix a leveling issue if you have one.

    Check your nozzle diameter too – that looks similar enough to glow-in-the-dark filament that I’m going to mention it – DON’T. Glow in the dark filament is as abrasive as carbon fiber, and if your machine isn’t set up to handle it, it will wallow out a nozzle until it doesn’t match what the printer expects. If it’s wallowed out, you’ll regularly end up with nasty surfaces, etc.

    There are so many things that this could be. Change your E-steps back to 93 if you’ve changed it. You’ll only mask the problem. If you’ve swapped over to some sort of dual-gear extruder (bad idea btw) - make sure your E-steps match what they tell you to use (typically 130) - or you can get this too.

    More, good, well-lit pictures of the extruder area of your machine would help diagnosis - hot end with the fan shroud/cover off might help too. Basically – the more information you can give us, the easier it is for us to help. Pictures do a lot for those with good attention to detail; as you might miss something that we won’t.







  • There really isn’t. That’s why Bambu has such a strong stranglehold on the market. The price/feature set balance is just sooooooo tilted in their favor right now that it’s hard to legitimately pick something else unless you are a stone wall when it comes to compromise in open source philosophy. If the open source philosophy and dogma aren’t really part of who you are, there’s no reason this change will affect you in the first place.


  • I don’t like Prusa all that much either, but they are A LOT better than bambu.

    In what aspect? Because it’s not reliability. Or speed. Or ease of repair. Or features. Or price.

    Jo’s been throwing shit at the wall as fast as he can to catch up to Bambu; and that’s good for all of us - certainly. But this isn’t a Bambu vs Prusa thing here. Prusa added the dogbone that voids your warranty if you want to flash a new bootloader to the buddyboard – did you have a problem with that? Did you cry ‘slippery slope’ back then?

    What about all the other great machines out there that are quickly catching up to Bambu’s feature set? The K2 seems to be quite interesting. There’s room for everyone here.


  • Still gonna be Bambu out of my mouth 9 out of 10 times. This change doesn’t affect most of my customers (to put it in perspective, I do over 1k unique 3D printer repairs per year).

    I’m still an open source enthusiast/zealot - but the fact is, most “normal” people, don’t give a flying shit about this stuff.

    This will be a footnote in my suggestions to them, however.


  • Because I’ve seen every open source company I love do the same thing over time.

    Makerbot. Ultimaker. Prusa.

    Remember the “Dogbone” you have to break on the buddy-boards to be able to flash your own bootloader? None of you people stopped buying Prusa back when that happened…

    This hasn’t been implemented yet, so we don’t know the full details - I’m gonna wait and see where the chips fall before being so reactionary. I’m also going to be a pragmatist, and not pretend that other machines out there don’t exist. Bambu will have competition soon - the K2 already seems to be picking up steam, and Creality has a pretty good history when it comes to this kind of thing. There’s plenty of competition in the market, and Bambu printers are good enough for most people for now.

    Kinda like the Glowforge (a laser cutter) when it came out - it’s got all the proprietary locked down stuff, and their users don’t care. But real C02 lasers still exist, and are popular too. There’s room for both.

    I’m not discounting those users who bought, and then had a ‘feature’ removed. I believe that’s terms for a class action if they don’t allow third party slicers to be used; but I don’t think that’s the full story of what’s going on here.

    My family and I are devout followers of the Satanic Temple (Not really ‘Satanists’ per-se however); and while yes - I know there are some problematic issues with the leadership, they still use what they are doing in a hilarious way to troll our government when they create christian-centered laws. A lot of what they stand for mirrors my own personal moral code before I ever discovered them. The freedom to offend, is just as important as the freedom of bodily autonomy. Without it, it’s impossible to push for changes.


  • I run a repair shop, and don’t own a Bambu Labs printer - also never will. I’m not their target.

    However, out of the easily 100+ customers I know that use a Bambu; maybe 2 of them use a different slicer. Most people won’t be affected by this change and it’s only communities with enthusiasts like ours that will end up caring.

    That said, Bambu printers are still a MASSIVE step ahead of even their closest competition. This probably won’t stop me from recommending them to consumers in the future, because while I am a zealot; first and foremost concern is that my customers are able to print reliably and easily.

    Additionally – The community always figures this stuff out. Bambu Slicer is open source, and I’m sure it won’t take much for them to get around this tiny little speed bump.

    This was my initial worry with them to begin with, and it seems to have been founded now; but until someone comes up with a comparable ecosystem, at the same price and quality of Bambu Labs, then it’s still a no-brainer to be purchasing them for 99% of people.

    You should still get mad, be vocal, and complain - they’ve reversed course before on other things (Linux Firmware) - so enough of an outcry should poke them into doing something different.





  • Reddit-tier behavior right here. Because you’re just looking at the mod log and attributing every thing ever modded to my entire history of posts. I participate in lots of communities, and a majority of my stuff isn’t ever modded or deleted.

    And it’s actually worse over here, because instance admins have access to the history of your up/downvotes, so they can dive even DEEPER and have been caught doing that exact thing.

    But way to miss the point - and then go even deeper in proving the point I was making; and being a great example of that point.




  • There is not a single product you use that doesn’t have the support of some trump supporter behind it. You gonna go live in the woods off of the fat of the land?

    The food you buy, probably 90% Trump supporters. Gonna stop eating? Drive a car? Use plastic at all? All Trump supporting oil barons. Gonna stop using that stuff too? No?

    But you’ll sit here and virtue signal that you’re such a gooooood person because you’re swapping over to another VPN…

    That also ends up having the same supporters behind it. Great, you hate trump, wooo you’re such a virtuous person, (news flash: I’m sure most people do) – Now come back to earth with the rest of us. Too many of you people let this shit live rent-free in your heads constantly.
