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.
It would have been more fun to paint cars if someone named the mixing colors like this. Yellow is actually quite rare in automotive mixing systems. You never see yellow cars. There are many you might mistake as actual yellow, but nearly all are a trick. There are usually 2 yellows that are used for tinting, mostly with whites. The primary black in automotive paint is actually yellow based. A tiny amount of black with a fine metallic is how most champagne colored cars are formulated.
Stump. I was a tree, but now a dump.

She has grown up in the era of me lying down all the time and has grown into lounging much the same.
Disconnect from their cycle and think for yourself. The news cycle is the primary problem. It is malicious theatrics. The further I have disconnected and distanced myself, for personal reasons, I only catch the periphery, but stuff makes much more sense overall. I write my own opinion and narrative because I have the space to form it.
We need DNS filtering to work on outgoing packages by default, and to make whitelist DNS stupid simple to implement for any parent and child processes. It should be as simple as launching with the command, including a preconfigured whitelist, and a pop-up message for "approve, deny, prepend to list." System wide and incoming packet filtering is insufficient for the modern world.
llama.cpp is at the core of almost all offline, open weights models. The server it creates is Open AI API compatible. Oobabooga Textgen WebUI is more user GUI oriented but based on llama.cpp. Oobabooga has the setup for loading models with a split workload between the CPU and GPU which makes larger gguf quantized models possible to run. Llama.cpp, has this feature, Oobabooga implements it. The model loading settings and softmax sampling settings take some trial and error to dial in well. It helps if you have a way of monitoring GPU memory usage in real time. Like I use a script that appends my terminal window title bar with GPU memory usage until inference time.
Ollama is another common project people use for offline open weights models, and it also runs on top of llama.cpp. It is a lot easier to get started in some instances and several projects use Ollama as a baseline for "Hello World!" type stuff. It has pretty good model loading and softmax settings without any fuss, but it does this at the expense of only running on GPU or CPU but never both in a split workload. This may seem great at first, but if you never experience running much larger quantized models in the 30B-140B range, you are unlikely to have success or a positive experience overall. The much smaller models in the 4B-14B range are all that are likely to run fast enough on your hardware AND completely load in your GPU memory if you only have 8GB-24GB. Most of the newer models are actually Mixture of Experts architectures. This means it is like loading ~7 models initially, but then only inferencing two of them at any one time. All you need is the system memory or the Deepspeed package (uses disk drive for excess space required) to load these larger models. Larger quantized models are much much smarter and more capable. You also need llama.cpp if you want to use function calling for agentic behaviors. Look into the agentic API and pull history in this area of llama.cpp before selecting what models to test in depth.
Huggingface is the goto website for sharing and sourcing models. That is heavily integrated with GitHub, so it is probably as toxic long term, but I do not know of a real FOSS alternative for that one. Hosting models is massive I/O for a server.

From 20 minutes ago... The sonic boom took 8 minutes to arrive.
I like the hacked breadboards so far. I made a sloppy super-breadboard. I should have glued it before soldering but was worried the glue might make it into the slots with the metal contacts. I also broke up the internal rails and labeled so that 8b data and 16b address all exist on the same set of 4 power rails.
I think I am having an issue with either some crossed wires or how Bus Request works with the Z80 versus how the Bus Enable of the 65x chips work. I think one or all may have some type of routine that does not high-z the buses immediately... a problem for tomorrow.
I watched Anton Petrov's last upload on the impossible merger of intermediate mass black holes,(https://www.youtube.com/watch?v=8p6PgXqL6OQ).
Do two orbiting black holes have a gravitational resonant effect that is different than a single object of an equivalent mass?
