My first printer was way back when Prusa was but a set of instructions and suggestions. Prusa did a lot of the research that caused other companies to succeed. And seeing what Bamboo is doing with it, it’s important for me to support prusa as I detest closed ecosystems.

So when it was time to get back into the hobby last year, I went for a Prusa Core One, and I’ve had no regrets.

It’s an excellent printer that is easy to use, and it’s very versatile, so that’s my suggestion.

The price tag is a bit higher than the competitors, but I don’t mind - they floated the R&D bill for the entire industry, and that carries an interest.

My home servers have generally a lot smaller attack surface, as only a few ports are actually routed to them, so in theoey I could get away with a more relaxed approach. But I’m also a big believer in defense-in-depth, so I follow the same rules of thumb:

• iptables (or equivalent) that drops anything incoming that isn’t wanted
• any public facing service (except ssh) gets its own user
• disable root login via ssh
• ssh login with key only on any user in sudoers

2. Kerbal Space Program
3. Minecraft

…don’t care about the rest of the list

Calibrations are important, but some of the defaults work well out of the box. Don’t expect perfection from the start, aim for “good enough” and improve over time.

• Bed leveling (tramming) is mostly automated these days, since it’s such a vital step
• Extrusion multiplier (a.k.a. flow rate) needs to be done on a per filament basis, but it’ll probably work fine with defaults. Dialing this in is useful, but not super critical in the beginning.
• Pressure advance… eh, no comment, as I haven’t mastered this yet. Suffice to say my petg prints could be better, and this is the likely reason

Beyond that, filaments vary in quality. Try to stick to one brand and type that works well for you and your needs and once you’ve mastered that, try others.

And learn blender (or anything else that can export to .stl or other supported formats). It turns your printer into a proper household tool you wouldn’t be able to live without. My house has so many functional prints that I wouldn’t be able to go back to not being able to print whatever doodad I need.

Well, there’s a footnote on my end: Me taking the drives home is a bit of a grey area, as the procedures say that the drives are to be mechanically destroyed when no longer needed. It doesn’t specify needed by whom. And I do attack them with my angle grinder, so it’s in accordance with company policy.

And yes, my employer knows and is OK with it.

I usually scavenge old drives from work. On one hand they’re a bit smaller than I’d like them to be, but in the other hand they’re free except from the minor work and documentation involved in ensuring that no company related data remain.

Yup, there’s no kinkshaming here

Under Tony Blair they were all merged into Department of Highland Security

A USB crapgadget built around a raspberry pi; It can record audio, stream video, mine bitcoin, it has a local LLM running, it takes voice commands, and it enumerated as a flash drive if you connect it to a host.

And it’s pretty awful at all those things.

All web servers are servers. Not all servers are web servers.

Web servers specifically serve HTTP and/or HTTPS, but there’s a myriad of other things. FTP, Minecraft, databases, mail, just to name a few

I wouldn’t say overpriced, as that carries the implication that nobody should pay that much.

But that it’s pricier than some competitors, sure. But they’ve basically floated the R&D cost for the entire industry, and that cost carries interest.

Already been to a few, but I never had the chance to visit Kenya

Prusa walked so other manufacturers could run. 15 years ago prusa were the ones who made 3d printing a viable hobby for the rest of us. And all this while keeping their designs and code open source.

Today I view the extra I pay today for their products as a well deserved reward for their integrity.

Joseph Prusa must be a happy man nowadays

Any chance the filament is unevenly extruded from the manufacturer? Try measure the spool in few places with some calipers to verify that the filament thickness is exactly 1.75mm, and that it doesn’t vary.

Also, might be worth it to check your flow rate/extrusion multiplier setting to ensure that the amount of plastic extruded matches what it is trying to do.

Sound advice outside of 3dprinting too

Your comment made me think it might be stripped teeth on belt(s) or gear(s)

From a 3d printing perspective, I have absolutely no idea.

But from the perspective of troubleshooting electronics, that’s a pretty awful situation: electrical shocks can cause all sorts of weird havoc with unpredictable behavior and unintuitive symptoms. If I was in your situation I would seriously consider cutting my losses short and replace ALL of the electronics and save myself from a major headache.

Source: I was tasked with fixing an MF/HF radio station that had been struck by lightning. And the ship it was on was only available around 0300 in the morning. I replaced so many components, including the ones that threw an error, but to no avail. I ended up replacing the entire station, antenna and tuner included.

Blender for most things, freecad sometimes

I started hosting stuff before containers were common, so I got used to doing it the old fashioned way and making sure everything played nice with each other.

Beyond that, it’s mostly that I’m not very used to containers.
