So there hasn’t been any RAM manufactured in Europe in nearly 20 years? Is that the point you’re making?

This, I think, is related to where I draw the line between a ‘moon’ and a ‘sattelite.’ If an average human can hit escape velocity under muscle power, it’s a satellite. If you can strand someone there, it’s a moon.

Mainland Europe has never had a culture of computer hardware development or manufacture. They’ve been coasting on the United States and Britain since WWII. Name me a CPU architecture developed in the EU. There’s one, ARM. British.

Furthermore, Europe just doesn’t have the work ethic to run a chip fab. You know those attempts to bring fabs to the United States? They’re running afoul of American labor laws, turns out American citizens won’t work 14 hour days like the Taiwanese. You lazy ass Europeans with your 51 weeks of vacation a year don’t have a snowball’s chance in hell of making your own CPUs.

not that I’m aware of; I designed the part with this shenanigan in mind and used PrusaSlicer.

It is in fact a fairly old, homemade budget printer.

I built this printer around 11 years ago, it’s a Folger 2020 i3, the company folded years ago. This is back before flexible PEI coated steel build plates were common; the bed assembly is a simple aluminum plate with a PCB heater suspended above it at the four corners by spring-loaded screws, and then the glass is binder clipped onto that. Glass was pretty much the meta for 3D printer build plates at the time because it’s a perfectly flat material that’s cheap and easy to source. The choice of a mirror over clear glass was mostly an aesthetic choice, though sometimes it can make it easier to manually level the bed, it makes it easier to see the gap between the nozzle and the bed.

This machine is pretty legacy by now and it’s starting to show some signs of wear but it does still work.

Oh, I just about forgot: One of the best things you can do is sit and watch it print, even as it’s going slightly wrong. That can be instructive. Watch it do things like overhangs, bridges, small features, etc.

It has been my experience that you can just forget about disk space usage when sysadmin-ing an old person.

The olds that I’ve set up with computers basically don’t move in. They go to a couple websites. They don’t create files, they don’t install a lot of software, they aren’t playing all 500GB of Red Dead Redemption 2. Like, I’ve gotten ready to move files across, prepared full on network connections or brought large external SSDs to transfer files from one computer to another or to copy them off of Windows to copy them back on with Linux…half a gig of pictures, maybe.

We’re talking about folks who might not install any software on the computer at all because they live in a browser.

I have Mint installed on my Aunt’s laptop, which she basically never uses. Fun thing I learned: APT can get constipated if it doesn’t run in a few months. It got itself somewhere you couldn’t GUI out of so I had to use the terminal. It needed something like an apt clean or an apt --fix-broken or something, the error message it gave me told me what command to run, but that needed to happen.

I think you’re alright, Mint’s whole thing is being defuckulated Ubuntu.

“All this slicer stuff”:

So an STL file stores the shape of an object by defining triangles by their vertices in 3D space. Kind of like a giant 3D connect the dots puzzle. I’ll note here: This is a close but imperfect approximation of a shape, especially curved surfaces are actually highly faceted. Other file types like AMF or 3MF or something might be able to do true curves, I’m not sure. An STL only stores the surfaces of an object, it is up to the program that is reading it to interpret the interior as hollow or solid or whatever.

Your 3D printer can’t understand an STL file. It’s a fairly simple machine, it’s got a couple heaters, a couple fans and a few motors, and it needs to be told what to do with them in very direct terms. Most 3D printers use a command langauge called G-Code for this; a line of G-Code might look like this: G1 X35.386 Y181.683 E27.01397 I actually copied that line out of a G-Code file. It’s commanding the printer to move the nozzle from its current position in a straight line to an X, Y and E position. E is the extruder axis, get used to that 3D printers actually track motion in 4 axes. G-Code is designed to be human readable and writable, and I suggest you learn a little bit about how it works for reasons I’ll get to later, but for the most part you’re going to use software to automatically generate G-Code, using a slicer.

A slicer is what we call 3D printer CAM software. 3D printers usually create objects by laying down thin, flat layers of plastic that can be described in 2D terms, so the software “slices” the model into a bunch of horizontal cross sections to arrive at a 2D shape, and then uses an algorithm to draw that shape using lines of extruded plastic. G-code has commands for curves and such but most slicers just use a series of very short straight lines.

The general algorithm is going to be something like “draw a few laps of this layer’s outline. Color inside the lines, and then move the Z axis up a fraction of a millimeter and do it again.” Things like how many laps it does drawing the outline, how densely to color inside the lines and in what pattern, along with what temperatures to heat the bed and nozzle among many other things are adjustable in the slicer’s settings. Almost all of the 3D printer’s behavior is actually decided by the slicer.

Including the little routines it goes through at the very beginning and end of the print. You’ll find a page in the settings that allow you to write custom G-Code that it will copy paste at the beginning of each file, at the end of each file, and sometimes between each layer. I have a Prusa-style bed flinger printer, and I added a command to the end script to run the bed all the way forward as if presenting the model, to make it easier to get to for removal. This is why I said it’s wise to learn a little about G-Code, so you can add customizations here.

Additional tools: I like to keep a pair of needle nose pliers near the printer to grab oozed filament, some side cutting pliers for snipping filament, I have some dedicated allen wrenches for the common adjustments on my machine, and a razor scraper for removing prints from the bed. Your machine may have different features than mine so adjust accordingly.

Oh just give it a minute. Europeans pretending they’re not following right behind the US, that their own right wing retards aren’t consolidating power.

Yeah, Denmark might actually try their stupid idea.

Well I mean, it was implemented about as well as California Prop 65, which had the effect of printing “This product contains chemicals known in the state of California to cause cancer” on literally everything ever made.

Uh huh, and how’d the Danish government arrive in power?

I have told this story several times.

In late 2013 or so, I bought a Raspberry Pi 1B as part of my amateur radio hobby. I did all my actual work on a Windows laptop, the Pi was pretty much just a toy, and I learned a little about Linux with it.

Mid-2014, the display in my aging laptop died. I was going back to school that fall, I needed a laptop. So I ordered a high end Inspiron from Dell. And Dell sold me a lemon. That laptop would just…shut off and never turn back on again. And then I’d call Dell’s tech support. They’d send a tech out within a week or two. He’d throw a part in it, and then it would last somewhere between days and seconds. After waiting over a week to get a tech to come out and fix it, it didn’t finish booting before it died again. I finally got them to replace the laptop outright, with a system that lacked many of the features I had explicitly ordered.

I am no longer a Dell customer.

That whole time, I needed a computer, and the only thing I had was that Raspberry Pi in addition to my Galaxy S4. It was real fun typing up homework in LibreOffice on a single core 700Mhz ARMv6 and 512MB of RAM.

I finally got a running Dell, after an entire semester, loaded with Windows 8.1. Windows 8.1 was a total pube fire. Linux felt more familiar at that point, so I tried a few different systems, discovered Linux Mint, and 11 years later I don’t have any computers that run Windows.

Well, I’m an American, and we’re collectively blamed for the fuckshit our government does, so absolutely yes.

But also, if the Danish government passes a law that goes into effect, how does it matter how many or how few Danes wanted it?

many don’t deliver enough power for a Pi 4.

What’s the difference?

Fun fact: Bell peppers are tasty.
