I have printed ASA on my Anycubic S1. It's enclosed but doesn't have an active chamber heater. It uses the bed heater to slowly heat the chamber. It's $350.

It technically worked the very first time but it still took like 3 prints tuning the temperature to get good layer adhesion. (I was printing extremely thin and narrow parts and the ASA would break along layer lines.)

Going only by YouTube reviewers, the Qidi Plus 4 seems to be the best low end for "engineering" filaments. $700 and out of the box it has a hardened nozzle, high temp hardened extruder, and active chamber heating- plus a 305mm build volume. Even their $400 Q2 has a hardened nozzle and active chamber heating.

While the U1 is incredible, it cannot do ASA out of the box.

If I were to buy another printer, the Snapmaker U1 is at the very top by a huge margin.

But I wouldn't recommend it for ASA. Out of the box it is an open air printer without active chamber heating.

The network effect. It's big enough that small forums get enough posts to stay active which keeps more people using it.

For example Lemmy has a 3d printer forum that has a few posts a week. Reddit has forums not just for 3d printing but for every specific model of printer and each gets a much activity as Lemmy's generic forum.

If I'm searching for something, Google will show Reddit content but not Lemmy because there isn't an answer on Lemmy.

He's using the wrong words. No printer has an accelerometer.

Automatic bed leveling requires a printer support it. Klipper can't do it if the hardware isn't there. Same with flow rate calibration. Manual in Klipper requires test prints and then editing the config files. Flow rate on modern printers is calibrated automatically using the camera.

Klipper can't do a bed mesh if the printer doesn't have a probe.

Manual bed leveling means using a sheet of paper and adjusting bed screws to get it at the right height.

People totally got killed by doing their own maintenance

People have totally gotten killed from maintenance done by a "professional" (new kid on the job at the shop.)

I watch YouTuber CarCareNut and he's shown many stupid mistakes made by dealerships.

I assure you I take greater care doing repairs than a tech who will get yelled at if they don't finish the job fast.

Yeah but my mp3's from Kazaa are all 128. I want to hear them perfectly as the original ripper intended without distortion from the cables. The gold connector adds warmth to the sound.

That said, I can't comment on her character,

Yoko described herself as a bad mother who twice abandoned her child in search of fame.

The argument that apes have never asked a question "is a classic example of overstatement," said Heidi Lyn, a professor at the University of South Alabama's Comparative Cognition and Communication Lab at the Department of Psychology and Marine Science.

"There is plenty of evidence of apes asking questions, although the structure may not look exactly like humans asking questions," Lyn explained.

Modern wine growers use astrology to plant?

I would think that's a tiny subset of the producers.

 

I'm working on some models and have found that if I add an SVG modifier, Orca slices it beautifully. But I'd rather have the SVG's "baked" in the model so it's easier for others to download and freely share the STLs and print without a 3mf.

The problem is that if I put SVG image in Fusion and then export the model, when Orca renders the G-code, the quality is poor to bad. The same SVG added in Orca looks great.

STL with decal built into the STL geometry in Orca:

STL in Orca after "Preview" so you can see the layer lines:

The same file but applying the SVG as a modifier instead of it being part of the imported STL.

Does anyone have any suggestions on how I could get an STL to have the same quality as using a modifier? Or maybe a way to go backwards from gcode to STL so that I can share the higher quality version that Orca creates?

 

I've been pricing out components for my first new build in 20 years. (I've bought many ebay servers and a few mini PCs in between).

The parts are around $2k. But then I look at the amd ai max+ 395 PCs that are out or coming out shortly and I think I might be buying an already obsolete platform. For the same price I'd get 16 cores and over 2x the memory bandwidth.

 

I've made some prints fit in my printer by printing them at a diagonal. I work it out by spinning it until I don't get an error from the slicer.

I'd rather be able to calculate exactly what will fit beforehand instead of spinning the model around in CAD or the slicer.

Has anyone found/used a calculator that can do this?

"Emmitsburg Mayor Frank Davis voted for Donald Trump in hopes he would cut federal spending. Now Davis hopes those cuts don't include the permanent cancellation of classes at the National Fire Academy, which is part of the town's identity and helps drive its economy. Davis is also a chief at Emmitsburg's firehouse, known as the Vigilant Hose Company."

Trump killed the Fema training academy. It's not coming back.
