This would make open source dominant and kill off all the rest. Big money will battle to keep digital slavery.

The only use case I see for helping with STL files at this point, is if the path to quads is made easier. As others have said, STEP is far better because it retains π. I do not do file sharing or print the designs of others because they are usually of dubious quality. Sadly, legislation has made the subject of connecting and sharing political with no effective push back from businesses in this space. If I am forced to chose between digital slavery with internet and disconnecting, I prefer the island life. In prep for that impending dystopia, I would not use any online service like this in my tools. I hope it is useful for someone. GL.

OCR tool+ to autogen a suggested alt text. The path of least resistance needs to be lowered.

Alternatively, inverting the paradigm is likely to cause less issues and push back. Add the automated tool the the end user in need of the version. This obviously creates the issue of data quality and trust, but for the smaller group. What if there was a reply field silently posted to everyone’s notifications feed indicating anonymous instances of the tool being used to fill in the gaps for alt text? The message would need to be opt out or carefully presented. Perhaps it could be possible to modify the post itself via the tool? Better yet, make the alt text field a Wikipedia style affair anyone with an account can edit, but with a lock available to the OP. That would create much more healthy awareness of the need for alt text, as people posting the content will see the places where gaps are filled by an automated tool. It gives them the chance to edit. This does little to initially improve the experience of the most active alt text users, but it creates a strong cultural shift in awareness that should improve the situation greatly in the long term IMO.

Complex social hierarchy is a super important aspect to account for too. In the proprietary software realm, you infer confidence in the accumulated wealth hierarchy. In FOSS the hierarchy is not wealth, but reputation like in academia or the film industry. If some company in Oman makes some really great proprietary app, are you going to build your European startup over top of it? Likewise, if in FOSS someone with no reputation makes some killer app, the first question to ask is whether this is going to anchor or support a stellar reputation. Maybe they are just showing off skills to land a job. If that is the case, they are just like startups that are only looking to get bought up quickly by some bigger fish. We are all conditioned to think in terms of horded wealth as the only form of hierarchy, but that is primitive. If all the wealth was gone, humans are still fundamentally complex social animals, and will always establish a complex hierarchy. This is one of the spaces where it is different.

I have no confidence it will work or last. I’m not committing to anything either, but at a minimum I need the flattest image possible, meaning a square lens to object from a distance where perspective distortion is minimized. The largest camera sensor (silicon die) will produce the flattest image with less perspective distortion. Each image must contain a known measurement, such as a little machinist’s ruler or other. The point here is that the lines of known measurement must be as close to single pixel accurate as possible. I will not take the time to straiten or correct for errors, - if I have the time and feel like making something. The result will likely be ugly and might not work or last. I need to know the angles and sizes of those protrusions to utilize them like a dovetail. I do not trust anyone’s measurements, especially my own, and I have no desire to dial you up for the ‘measure thrice print twice, measure once unfinished dunce’ - rule. I need the Cartesian planes of X, Y, and Z, (right, front, top) at a minimum.

I probably do not have time within my project, but if I’m bored and waiting on a long print, maybe.

The cheapest fans available often have a lot of injection molded plastic that squeezes out of the gaps of the metal mold when the plastic parts are formed. Removing this may help some.

The cheapest fans now come with the small motor shaft embedded into the frame with a tiny ball of metal formed at the end of the shaft. The ball is what prevents the shaft and fan blade portion from coming out of the housing. This type of bearing and retention cause more friction than a design that uses a bushing and a small plastic retainer ring. They type with the retainer ring are usually floating in the magnetic field. The little plastic retainer ring on the shaft end is only present in cases where the fan is dropped causing more force than the magnetic field will hold onto. If a person such as yourself, presses on this type of fan at the fan blade hub, you will feel the magnetic field and see the hub deflect and then return to the center of the field. Spinning it will feel frictionless. With the ball shaft type, there is little deflection and it feels like a bit more friction when comparing two side by side.

With the ball shaft type, most of the noise will be coming from the friction and transmitted through the body of the enclosure. If you isolate the fan with some damping between it and the enclosure it will reduce the noise considerably. Damping the enclosure, and adding rubber feet between any table or surface may also help.

Check DNS logs. Discord is proprietary undocumented garbage that connects to dozens of raw IP addresses that have no documentation, rhyme, or reasoning. You have no clue what or who is connected in that mess of garbage, or why they are there.

It is about like, I’m going to give you access to a phone, a special phone, it just works.

It is a prison phone. You are in prison when you use it… technically. But you don’t really “see” the “place”. The other inmates are all around you. They see you, but you don’t see them. Never mind that though, the phone just works. Lots of people love that phone. Nobody asks questions. Just use the phone and pay no attention to all the rest. It will be fine.

Business model? Viability? Never mind all of that. Don’t ask questions like that. The numbers do not add up in the slightest. That is the magic of prisons. Justice costs a lot, but it is worth it right. Magic phone is easy. Ask no questions. Expect no answers. Totally normal, everyone is doing it.

The whole thing is a mass of clueless zombie morons that ask no questions and have no idea who what or why they are connected to with all those raw IP addresses. They all give trust blindly without accountability or understanding.

Is fluxer as network f’ed up as Discord without the minimum democratic standard of human readable domains, or is it the slavery of dozens of undocumented raw IP addresses?

My experience may or may not apply here… In automotive paint refinishing back 15+ years ago, 2 part epoxy primers are special. Most primers are (were) 2k urethane. These are similar to automotive 2k clearcoat in how they work. They both have similar thicknesses, leveling after wet coats, and to a lesser extent - drying properties. With drying properties, the surface levels within a minute or so but it forms a surface film and the back side remains tacky for longer. (Where they differ is that clearcoat takes much longer to fully cure, like weeks to months, while primer is workable within an hour or less.) Epoxy primers are high build fillers. They get hard as a rock and are a pain in the ass to sand down. The two main reasons for using an epoxy are for super rough large surfaces, and this the the relevant bit here, they are used to seal the surface.

In paint, there are a ton of nightmare situations. Like let’s say some brake fluid got on the paint in a crash, or some idiot used rattle can enamel on a car. Often what happens is that the repair I am doing is not the first time the panel has been repaired. While I would like to clean the issue completely and use typical 2k primers, the previous repair may have used epoxy and buried something terrible. I’m not going to strip the whole panel and have to spray additional adjacent panels to color match when I did not estimate this in the cost quote. Epoxy seals out EVERYTHING. With stuff like spray can enamel, the painted surface never cures. It remains reactive to the solvent of anything sprayed on top of it. If ABS trim or bumper covers are exposed to acetone, similar issues with reactions will happen, unless 2 part epoxy primer is used. Epoxy primer is impermeable in the context of automotive paint; it is the nuclear option. Everything else allows some solvents to pass through it over time.

If you have ever touched the paint of new cars and noticed the softness, that is uncured clearcoat that is still venting solvents in small quantities. This is also why jams painting inside of the seals is kept to a minimum clearcoat thickness. The thicker the clear, the longer it will take to fully cure. As an ex pro painter, that softness tells me a lot about a finish too. It actually starts forming around 5 minutes after the clear is shot, just after the fingerprint test does not pull a string when removed. That is the first moment when I am able to barely graze the surface with fingertips and not damage the surface. It is still very wet underneath at this stage.

Hopefully that illustrates how even the hardest of painted surfaces is still able to allow stuff to pass through it. If you want to stop that stuff, you need a paint that is made specifically to seal everything.

That said, the seals and other materials also need to be up for the task. Most of those are likely just dust seals. How you deal with corners is critical. Just look at stuff like Pelican cases.

Yeah. Got a kit of it from a thrift store years ago and try to use it in jigs to save printing when possible… 4.3mm bolt holes, 7×2.3mm square nut slots and 12.7mm pitch. I have it and M3 memorized.

It is just a cleanliness standard. It is not required. I spent a decade in the details of automotive paint. I only covered the surface basics for paint. What I call clean for paint is an order of magnitude more dirty than a surgeon, and they are orders of magnitude more dirty than a silicon chip foundry. When it comes to making plastic stick and look pretty, an automotive painter might be helpful for framing the scope of what is possible. All I can tell you is I have a Prusa and never have these problems, so I explained my experience and methodology as to why I do as I said. Again, sorry this upsets you.

I have not had problems with glass or PEI. Your other comments indicate you tried ABS. That will never work without an enclosure, and even then, it will not work particularly well on any Cartesian machine. Sorry that illustrative examples and abstractive reasoning are offensive to you.

It can coat the inside of the drier. Use Bounty paper towels as a control when in question. Bounty are often used in automotive paint shops for a few reasons, but they are trustworthy for composition. If the two plies are separated, they make a good strain filter. That is the primary reason they are used. They also tend to be lower lint though not perfect. A tack cloth is used in the booth with controlled filtered air flow either across or down draft, so it is not a concern for perfect paint.

One of the tricks of automotive painting is to add a couple of drops of Palmolive dish soap to the water bucket used with wet sanding. It makes 3M Imperial Wet/Dry sandpaper last several times longer and acts as a mild degreaser the whole time. Any residue is cleaned in the booth stage using a special Wax and Grease Remover solvent that is the least reactive of the painting solvents. While this solvent is used extensively, still the fact that Palmolive dish soap can be used at all indicates how it is clean, consistent, and chemically irrelevant. Automotive paint reacts with many chemicals but specifically silicon is the worst problem. It causes fisheyes aka little divot like holes to form in the clearcoat. In most situations involving contamination and adhesion, silicon is the main issue that will be very persistent. It is so bad in automotive paint that in the worst cases, we turn to adding an actual silicon solution into the 2k clearcoat and trying to guess what concentration will match the problem area to level it. Otherwise, the entire job must be stripped to the raw surface and start over. Silicon issues only show up in the final wet clearcoat layer shortly after it is sprayed and leveled.

The reason why I have written all of this is to illustrate this point: the silicon is essentially floating on every underlying layer. The solvent has wet the area and the silicon just floats to the top of some filler, 2k primer, sealer, top coat color and when it gets to the clearcoat it blows a hole through it. There are two solutions. Use a two part epoxy primer that is a pain in the ass to sand, or clean the the raw surface with lacquer thinner or virgin acetone. In automotive paint, those two solvents are dangerous for causing a ton of other contamination and reactions issues. However, these are the only solvents that will take off silicon without diluting it and making the problem worse. Alcohol is a joke with no place in the automotive paint world when I was painting. I got out before water based stuff ruined the industry by making refinishing exponentially more expensive. That is only the color coat and some primers, so there may be alcohol used in some way in these, but it will not involve cleaning. Tire shine is the main source of silicon issues in automotive paint.

I have the empirical experience to know what I am looking at with cleaning and solvents. Alcohol is okay for minor issues, but think of it as constantly diluting and wiping the problem across the whole surface. Eventually, just use some virgin acetone to actually clean the thing properly. Paint is just plastic too. Each type requires a different type of tooth to mechanically bond to. With printing, I use 600 grit to lightly knock the shine off of the print plate surface. I go lighter on the textured sheet, but I only use the textured sheet with PETG because it is the only one that takes the textured pattern completely without showing layer lines. I print weekly on average, and use acetone and sandpaper around once a year. When I use glue stick, I clean the plate with dish soap after. I use alcohol in between. You will need an enclosure for ASA, ABS, and any larger PC prints regardless of the sheet or glue. Two IKEA Lack tables with legs stacked using double sided screws, then a clear shower curtain liner, and some tack nails does the job for under $50.

I would never use towels from any drier that has ever had fabric softener used in it for automotive paint. That is a contamination nightmare for me.

PLA will be better for hardware store and hobby junk. You cannot use automotive class finishes and expect them to last. Generally stick to one brand. Most paints are formulated for steel. ABS is the closest to steel in thermal properties. The expansion is the most important attribute. PLA has a different thermal profile so catalysed 2-part paints will not work very well long term. Rattle can enamel is junk by comparison, but it never fully cures like automotive paints. That property helps it stay in place longer in general. There are special adhesion promoters like bulldog for automotive stuff, but the thermal properties will still be an issue.

Pro automotive paint is 99.9% sanding and prep work. It is far more intense and rigorous than people realize. Perfection happens in the prep work. The actual paint is just a way of showing off that perfection. Mastering automotive paint is actually all about defeating yourself. Perfection is not subject to your emotions or expectations. It is right when it is perfect.

You want the highest pressure spray cans as possible. Also, if you do not used all of the can at once, flip it upside down and clear the nozzle by letting the siphon into the empty void and spraying. If you have a compressor that does not shoot out a bunch of oil or water, a cheap Harbor Freight pink gun with the nozzle of the can beside the spray gun will work wonders by atomizing the spray far more effectively.

You are solely responsible for vetting the software that you choose to run.

I do not review or care about the tools a person uses to create their projects. I appreciate the disclaimer when the person discloses their aptitude and confidence in their code.

Free software and Unix culture is a culture of hackers. Stallman’s very degree is in AI. Emacs is mostly a thing because lisp was adapted early on for AI development many decades ago.

Junk code is nothing new. X11 is notoriously bad, yet you likely have parts of it running on your hardware. Proprietary code is far far worse than anything a hacker posts as open source, yet you are running proprietary blobs on whatever device you are looking at now. Even if you are like myself with a libreboot machine, Leah readily admits that you need to run the core duo microcode if you want it to run right, and are not using that hardware for your primary device. The culture of antiAI is dogmatic nonsense. It is a tool, not a religion. It can be used harmfully or helpfully. I can’t fix stupid in anyone except myself. I do not fault anyone for what they run, the projects they share, or the background they come from. I encourage everyone to be positive and help their fellow hackers. I value participation and enthusiasm. Dogma and negativity are toxic.

I am ultra liberal. You have a right to all information, a right to skepticism, a right to error, and a right to protest in non violent forms aka the right to offend others. You do not have a right to infringe the rights of others.

This anti AI populism infringes the rights to all information and right to error if any administrative actions are taken. Your right to protest and skepticism is duly noted. If these become toxic in any ways that alter the dissemination of information, or toxic/harmful to the individual sharing information, I will remove the offending comments. If the person continues, I will escalate. I am only the janitor here. I clean up the messes. I do not matter, but neither does anyone else here. It is a community, and only the community matters. Garbage software is bog standard. Crusade against things that matter like proprietary software leveraged hardware theft and SaaS.

Thanks for sharing.
