- Comment on Is my stepper motor failing? 1 week ago:
It was, in fact, one of those tiny bearings.
- Comment on Is my stepper motor failing? 1 week ago:
Welp, it was one of the tiny ball bearings of the extruder gear axle.
- Comment on Is my stepper motor failing? 1 week ago:
UPDATE:
It apparently was a damaged ball bearing. Upon opening the extruder once again I found some black grease littered around one of the tiny bearings that’re supporting the extruder gear axle. Replacing them solved the issue, many hours of printing with no angry cicada in my printer anymore.
Would’ve never expected such a tiny thing to make this much ruckus.
- Comment on Filament won't adhere? 1 week ago:
Something I didn’t see mentioned so far: have you checked if your nozzle is perhaps too old? I had filament curling upwards and creating blobs due to a nozzle being too old. Especially brass nozzles can wear out rather quickly if you use your printer regularly. If the filament would like to stick to the nozzle itself or move sideways (i.e. curling up when extruded) it rather quickly screws up prints.
Simplest way to check is of course to use other filament.
- Comment on Is my stepper motor failing? 1 week ago:
It’s no fan, I checked that. Also definitely comes from the extruder assembly, I could slightly manipulate it if I was pushing on the filament from above.
- Comment on Is my stepper motor failing? 1 week ago:
I’ve checked the print it was working on and changed the Z-offset, had no influence on these scraping sounds. It’s definitely somehow connected to the extrusion, that’s why I assumed it to be the stepper.
Do you think those really tiny bearings used for the extruder axis’ can make such a sound? Other than that I’m really out of ideas outside basically sanding down anything that could be the problem… I even made sure to print the whole MK4 extruder you see in the video on the Prusa MK4S of my local hackspace to make sure it has perfect dimensional correctness etc.

This is some prime authoritarian bullshit. Who needs properly declared laws and rules anyway, the current administration are “the good guys”, right?? They’ll just tell you if you’re wrong.

Probably like a huge chicken.
- Comment on Looking to get my first 3d printer, any suggestions? 2 weeks ago:
My guy, first off: the current most powerful printer is the T250, which is 100% open-source. Secondly: Neither Printables (Prusa) nor Thingiverse (Ultimaker) needs a registration for people to download stuff. Not defending Thingiverse or Ultimaker, they definitely also did shit. But that doesn’t mean you have to step right into it (unless you’re into such things). Prusa also made some weird choices (by far not as much as others though). Thirdly: even modern printers with fancy new tech like toolhead switching can and are being build with Klipper as their control software (Snapmaker U1), and Sovol based their company around offering easy-to-use printers with off-the-shelf parts closely based on Voron designs. And I probably don’t need to explain how Prusa operates. None of them are perfect kof course, but there’s zero need for the kind of enshittification Bambu and Creality now stand for.
These cheap hobby printers went nowhere until Bambu started up.
You’re deluded. There’s nothing special about Bambu printers, except perhaps their (by now) awful failure rate and printer recalls. Although it might indeed be special to build printers where the hotend successfully melts itself, the newest problems with the A1 (not the first time Bambu printers are suffering from thermal runaway due to bad thermistors, literally the most dangerous failure there is). The one thing they do like a pro is marketing and capturing marketshare by selling underpriced hardware with increasingly closed software through influencer campaigns.
To call everything that already existed when Bambu was created “cheap hobby printers” is just absurd.
All 3D printing that is practical is backed by VC.
Rofl, so Prusa printers aren’t practical. Noted.
- Comment on Looking to get my first 3d printer, any suggestions? 3 weeks ago:
The older ones can get mostly hacked (not sure about their newest devices), but given Bambu’s increasing reliance on closed source code, custom parts that are not easily replacable and their financial need to lock people into their ecosystem (they’re backed by Venture Capital) it will be a constant fight. And you never know if they’ll lock down something with the next patch. Not to mention that, by using their services, you’re forcing others into soft-dependencies as well (e.g. their model website “MakerWorld” requires everyone who wants to download more than 5 individual parts to register = more data and ads for Bambu).
There’s no reason to buy into something like that.
- Comment on Looking to get my first 3d printer, any suggestions? 3 weeks ago:
If you can stretch that a tiny bit perhaps the Anycubic Kobra S1 is an idea (I think I saw that machine for 369€). Apparently not much for tinkering, but a cheap “just works” device with probably the cheapest upgrade path for multi-colour printing. Its enclosure also enables you to immediately try out more demanding materials like ASA (for UV resistance), ABS or Nylon. And of course PHA, the only truly compostable material (not yet too common, but f.e. Colorfabb sells those).
I see a lot of people recommending Creality. Be aware that Creality is about to go public. There already are signs of enshittification since they announced that plan (incl. a website for 3D models filled with stolen work and AI trash), so I’d avoid them as much as Bambu.
For filament I’ve had some really bad experiences with cheap stuff as well (tangles, air bubbles, dirt etc.), so I’ll add some recommendations too. Mind that this is just my personal experience.
tl;dr Cheap printer: Anycubic High quality printer: Prusa To avoid!: Bambu, Creality
Cheap filament: TINMORRY, eSUN High quality filament: extrudr, Prusament, Colorfabb Recycling filament: Recyclingfabrik (EU), Prusament
- Comment on I'm Unable to get any PETG HF Filament to Stick on the Bed after having Switched from a 0.4mm to a 0.2mm Nozzle [Bambu P1S] 4 weeks ago:
That’s how I solved my adhesion issues as well (with ASA and a .3 nozzle, but should be the same in principle).
- Comment on Accessibility is important 4 weeks ago:
I heavily disagree. As a visual learner I need pictures. Everything is visual to me, even math, language, programming… if you give me a wall of text using abstract terms I won’t understand shit. I require graphs, visual representations, mindmaps, something.
It might not be the optimal medium for everyone (there is no universally accessible medium for anything!), but to argue that pictures make things less accessible is just plain wrong.
- Comment on The Saga Of Hacking A Bambu X1 Carbon 4 weeks ago:
It’s the kind of enshittification Bambu is moving towards. I kind of expect them to do something like this in the near future, only allowing the “correct” filament and hiding the full potential of “your” machine behind subscriptions nust like car manufacturers.
- Comment on Indoor lettuce growing in 3D printed pots 5 weeks ago:
Depends on the usecase though. If it’s something you could reasonably lose in nature (like markers you put in the ground, small signs and such) I’d rather use pure PHA. It will degrade of course, but that’s a good thing after all. I’d rather reprint some small utilities occasionally than damaging the very nature I’m trying to foster after all.

- Comment on Polypropylene as a filament - lost in tech 1 month ago:
Are there any technical / mechanical capabilities (outside of its flexibility to produce sturdy springs and such) of PP that only it can provide over other, less environmentally damaging materials?
I’m always trying to stick with materials that are either compostable (PHA) or truly recyclable (PLA, PETG) unless there are properties I absolutely need (like ASA for UV resistance & strength or TPU for flexible & protective parts). I wonder what PP does over TPU or other more common filaments and how it compares in terms of sustainability.
- Comment on Router suggestions for a complete noob 1 month ago:
Not sure about the availability in your region, however I have good experiences with AVM Fritz!Box routers. They are proprietary but extremely easy and reliable without sacrifycing security or features. They’re from a german company and basically the go-to router vendor here by both ISPs and in retail.
- Comment on Stealthburner extruder grinding 2 months ago:
My printer currently sounds similar, also the extruder (i3 Mega MK4 X-Carriage w/ DD). It doesn’t impact the print quality so far, but I really wonder what it could be.
In my case it’s especially noteworthy that it only happens sometimes, depending in speed and current direction of the head. Perhaps this really is the sound of a bad bearing, with yours being really fucked already?
- Comment on Microwave Intensifies 2 months ago:
Reminds me of the diy antenna made out of copper wire, an empty CD spool and a single CD on its back. Those antennas could work as far as 1km if there was no obstruction, or 400m through light obstructions. It was awesome.

That’s guilt by association. Their viewpoint is awful.
I also wished there was no security at the gate of concerts, but I happily accept it if that means actual security (if done reasonably of course). And quite frankly, cute anime girl doing some math is so, so much better than those god damn freaking captchas. Or the service literally dying due to AI DDoS.
- Comment on Destroyed my Glass Print Bed - What to do now 2 months ago:
The magnetic plate indeed warps, not due to heat though but the material on it warping. I saw that on both the i3 Mega as well as a Prusa MK4S with PETG and ABS. Printing big solid objects close to a corner would cause the corner to be lifted up, as the warping of the object is often times stronger than the magnetic plates. Probably gives you an idea of how much force a glass plate has to withstand, especially with badly warping materials like ABS. You can counter this issue with some strong clamps. Doesn’t happen on most prints anyway, only on really large and solid ones. The magnetic adhesion in the center is strong enough for anything.
- Comment on Destroyed my Glass Print Bed - What to do now 2 months ago:
I did exactly that to my i3 Mega to attach the magnetic plate directly to the heat plate. I indeed bend the whole thing in the process, fortunately though I was able to fix it (Z-Probe reports a maximum difference of 0.37 now). Don’t recommend though.
The industrial-grade glue they used is an absolute nightmare. If you choose to go that route definitely get yourself a proper heatgun as well as acetone, a spatula and some safety mask (for the acetone fumes). If you got an oven for tinkering perhaps heating the whole thing up to weaken the glue.
Leaving the glass plate where it is and putting something new on top definitely is way easier. Not sure I’d do this a second time myself (probably not).
