Recently got the cheapest klipper 3D printer called the Kingroon KP3S V2 because I need to make parts on the go. For under 200usd let's see how good or bad it is.

Every printer is a Klipper printer if you swap enough parts.

Finally got my Creality K2 to print some cubes though. Without any of the Creality crap really, camera works, Orca works, etc.

Need to move on to printing something "useful". And maybe some day I'll try the filament changer.

It amazes me how many people on-line are bitching. "I ran it out of filament and there was a line in my print." "The power went out and when it resumed there was a defect." I dunno, maybe put it on a UPS if your power sucks and don't let it run out of filament. Sigh.

I bought a PETG Carbon Fiber filament, I heard that there are some health issues with CF filaments. Should I add to my printer a fume extractor or the danger with these filaments is if I decide to sand my 3d prints?

Printing: If your printer is enclosed, you can build a 'bento box' air purifier for inside the printer or build a powered fume vent to the outside. Or wait an hour after the plate is cool.

Sanding. Yeah. Use a sander that has a wet/dry vac hose attach. If you are 'dremel sanding' use a fume station or a 'big mouth' wet/dry vac attach.

The 3D printer community is stuffed full of retards. I'm in one on Facebook merely to see what sort of dumb shit they get up to.

Last night my printer decided to lose its z-axis, it then proceeded to ram the print nozzle into the build plate and permanently gouge an outline of what I was trying to print into the build plate. FFFFFFFFFFFFFFFFFFFFFFFFffffffffffffff.

So sorry for you. I've been there.
There are lots of chinese after-market plate stickers or even entire replacement plates.

Or, If it's not too bad, you can wear your scars with pride...

It wouldn't surprise me if your nozzle got fucked up as well, probably should check that too.

I ordered the kit version of this wee beastie last week:
prusa.png

Holy shit, I tried to just save the image from the Prusa site and encountered my first .AVIF in the wild. I have regrets.

I was really on the fence for a while, Bambu vs. the Creality. I've had a CR-10 for years now that I've grown attached to, but I was really gay for the LIDAR sensor. Well turns out, the Bambu printers are locked-down as a nun's pussy. Even the custom firmware is like an "overlay" rather than a complete firmware image. My buddy got the Creality, and it's yuuuuge, but I decided I've already earned my fucking 3d printer scout badge and decided to buy something that just works and will last for years. Also the upgrade-ability of the Prusas sounded nice. I intend on getting the MMU later this spring. Apparently the MMU wastes a lot less filament changing than the Creality one poops out. I know I could get more bang for my buck with the other guys, but I'm tired of troubleshooting chineesium shit. And while I can reflash the Creality as easily as the Prusa, it dawned on me that I shoudn't need to reflash the Prusa which is nice. I'm also tired of building Marlin with all the custom shit for my CR-10 every time I want to add something.

Personally I think this is the way to go. The only downside I could possibly see is that they still only use 1 stepper driver for the Z axis even though it has 3 motors. We'll have to see if that winds up being a bottleneck. I love my MMU3 on my MK4S. The waste is super low and as long as you build it correctly it'll work like a champ. The buffer kind of sucks because it takes up so much space, but I'd recommend that above any self-rewinding spool holders as those have their own issues.

Don't worry, even Bambu guys will say it's very gimmicky.

Seriously? I thought the bullshit was ironed out and the LIDAR was demonstrably better than the typical induction/touch sensors - confused.

So much bullshit in this sector...

Anecdotally I don't think the LIDAR on the X1 Carbon does much outside of auto-calibrating flow rate. For first layer consistency I've had roughly the same experience with eddy current sensors (Beacon), touch (Prusa's loadcell), and the arcane dance that the X1 Carbon does. I've become a bit disillusioned with my X1 because it just has random ass failures that don't seemingly make any sense (random z-offset issues, layer shifts with .6mm nozzles, random thermistor failures), should be way better at printing ABS than it actually is, and Bambu's firmware garbage. I've heard tell about BTT working on a replacement board for the X1 that'll make it an open source machine, but I don't know what kind of timeline that's on nor whether or not it'll be worth anyone's time.

I had a tad bit of leftover filament left in my grey roll and someone suggested something kiwifarms related...so I made this little token. Feel free to do whatever the fuck you want with it irdk

Leave one along with a black rose on someone's doorstep when they've been dox'd.

That's true but this one is plug and play out of the box klipper ready. I got an enclosure for it so no reports on print quality or software experience yet.

I've also heard rumblings that Bambu will be locking down their printers when it comes to printing firearms and associated parts (if they don't already). I know not everyone buys their printers to print guns, but if you bought the thing you should be able to print whatever you want.

Honestly it's unwise to try to print anything like that on a printer that is network connected anyway. With some of the shit ass legislation that New York is trying to push, it puts into question printing lowers either way. I'm a huge advocate for self-built machines if that's your goal. They can be way more expensive, but you control what they can and can't connect to, you can write your own firmware, and don't have to worry about external connections. Otherwise, just keep things off the cloud and I think you'll be fine. I'm still banking on BTT creating a replacement main board for Bambu printers that circumvents the DJI inspiration wholesale.

I can't see Bambu giving a shit what you print, so long as you've paid the piper. I can, however, see them stealing anything remotely interesting intellectual property-wise.

If you want to build your own machine from scratch, the Voron project is cool. I considered doing one, but I'm just not interested in spending that much time on the project. They're still pretty neat.

I'd also recommend Voron but only because I've built 2 and have nearly finished my third. Candidly the design of the 2.4 is convoluted and not really worth your time. To your point, they're a massive time investment either way, so if your goal is printing then just get something ready made.

Daily reminder to air-gap your printer.

A team of minor attracted persons academic researchers (Montclair State University) partnered with cloud-based 3d printing management platform 3DPrinterOS to develop a 3dprinting tool. The tool detects if firearm components are being printed, and will block/abort the print.
This unholy alliance is targeting popular 3dprinter manufactures to force-feed this algo into their code.

Development goals include print terminations and surreptitious alerts to federal, state, and local authorities.

Print&Go is also using this algorithm and have developed a tool called 3D GUN'T.
No, I am not kidding.
3D GUN'T has developed a database of 'ghost guns' and firearm components. The software boasts about the use of AI to continually update the database. Additionally, the software logs every print into an encrypted file accessible to authorities. It also uses the 3d printer camera(s) to monitor, record, and terminate any print of 'ghost gun' components.

Of course, our glowing agencies have nothing to do with these efforts

I wonder how it works. Do they use AI to detect gun shaped prints or do they take known gun files and add them to a block list?

If it's the latter, you can use CAD software to tweak the file a little (IE: imprinting "Lol Gun't" into the plastic) to change the hash of the file. Whoever came up with this should fall down a set of stairs and land on a pile of Legos.
