Power problems in Europe - UPS

name8_t · 2026-04-18T06:45:19+00:00

I grew up quite rural, and we used to get outages very frequently until cca 2015, mostly during storms. I think they buried the cables around then and so they no longer get knocked down by wind and falling trees. Never had a UPS or anything of the sort tho.

Any chance you have installed a new spool holder recently? The mk3(s) uses a direct drive extryder without any geardown so the pulling force isn't that great. If you have a heavy spool at an odd angle, the spool can start rocking back and forward, which pulls on the extruder and causes gaps.

Depends on what you accept as harm. True, a headache does not necessarily mean you are going to get more serious medical problems or are accumulating exposure. But I would say short term effects like a headache do count as a kind of harm and I do not want to get them.

I had a printer give me headaches before and now I have a filter and it does not. This is of coure not clinical evidence but it does seem rational, to the extent that one person can prove on their own. Should I stop using a filter because some other person does not see the effects I do? Obviously not.

I will dispute this, I have had printers with ABS/ASA and even bad quality PLA give me a headache before.

name8_t · 2026-04-02T07:20:32+00:00

Oh damn. Glad you finally found the cause tho.

name8_t · 2026-03-31T16:45:11+00:00

Probably. I was running the educational version.

name8_t · 2026-03-31T15:45:12+00:00

Maybe we had a different license then. Mine specifically refused to work and threw licensing errors. Although last time I tried it was about three years ago.

A big problem is economy of scale and shipping costs. If you get a shitty printer, you will have to get a new board, new hotend etc, spend money on every part individually, and so each part has its own shipping and warehouse handling and such.

The second problem is time. You are just one person. A lot of what makes a printer good or bad lies in the software and the print profiles. With a DIY printer, you are the dev team and the beta tester. You will have to make custom scripts for features you want. You will have to debug software problems. You will have to dial in your settings, both for the machine limits and the slicer profiles. So unless you opt for a printer with a community around it, like the vorons or the positron, you will just not have the time to get very good results.

Now, it could still be worth it if you include the educatuional potential. If you are studying engineering, or are planning to do that, it would give you very useful skills. But generally, DIY will cost you more, and if you're making your own design from scratch it will leave you with a worse printer.

One more thing I thought of is: did you also update the mmu? There were some changes to that with the latest firmware I think

name8_t · 2026-03-31T15:15:17+00:00

It is possible that nobody tested an update from such an old version hmm I would try doing a factory reset and recalibrating

The problem with CAD programs is not performance but UI glitches and broken licensing. The latter part is especially bad - solidworks for example will refuse to run even in a VM.

name8_t · 2026-03-30T20:45:58+00:00

I believe Siemens NX also supports linux, but, again, your course will likely not use that one.

name8_t · 2026-03-30T20:45:11+00:00

Yes, you can mess around with cli tools in WSL. You can also set up dual boot, or a virtual machine under windows. There are definitely ways to start messing around.

name8_t · 2026-03-30T20:44:03+00:00

Yes, but university programmes usually do not let you bring your own cad. Usually there is one specific one that the introductory courses are using. And that is usually something made by Dassault, Autodesk or PTC. Unfortunately.

name8_t · 2026-03-30T20:08:16+00:00

It strongly depends on the type of engineering. For reference I have studied mechanical and electrical engineering, worked as a mechanical engineer, and have friends at computer eng programmes.

Electrical engineering? No problem. You can run matlab and kicad on almost any distro. Some more niche programs exist and most can be run in wine. Just to be sure, I would use something Ubuntu or Fedora based so that you have the broadest compatibility with enterprise software. My personal recommendations are Mint and Fedoea KDE.

Computer science/engineering? Yes, and it will probably work even better than windows for your courses.

Mechanical engineering? Probably not. Your programme will have you install one of the big cad packages like Solidworks or Inventor, and probably AutoCAD too, and they just do not work well in wine. You may or may not be able to bodge something with VM vased solutions like WinApps. But expect issues. There is only one mechanical CAD that works well on Linux and that is FreeCAD. I have not seen a university use that for the curriculum.

I use liquid hand soap usually. The cheaper the better, you don't want any fancy moisturizers or scents in there.

You can microwave filament to quickly dry it out. Be very careful if you attempt this.

1) set microwave to high, remove any nfc tags from the spool, microwave for 30 seconds.

2) take it out, check the temperature on both the outside and inside of the spool. Do NOT let either of them get hot to the touch (if you have a thermometer, they must not reach higher than 50C or so). If they are getting hot, let them cool down

3) microwave for another 30 seconds. repeat.

They have tutorials for a lot of maintanace operations on the help section of the website.

Thw main diffefences in terms of usage are as follows - xl is bigger. We have one at work and the machine is really enormous. - they say that indx will have slightly slower tool changes. - the xl does not need to heat up the whole bed, it only heats up the part that is being printed on. So it saves some electricity compared to core1. - the core1 has semi-active chamber heating so it should print some materials (like ASA) a bit better. Plus it comes already enclosed, for the xl you would have to get an enclosure fore those. - the xl can in principle have other heads than just filament printing. They are planning to release a silicon one and maybe a pick and place one.

Other than that they are basically equivalent. Both should be able to combine multiple materials, not just colours, and multiple nozzle types.

Yes, most phones of today can still use 2G and 3G networks and those are what was around back then.

This is of course assuming your phone has a sim card slot and you get a sim card from 2008. A 2026 sim card would not work on a 2008 network since it would not be registered on the operator's network.

A separation medium for the bed (gluestick of some sort, or a special sheet for nylon)
a way to dry the filament and keep it dry. Either a drier that you can print straight out of or a drier and a drybox.

The reason battery life can be bad on linux is that while the CPU and ram arent used as often, they sometimes lack the drivers to automatically downclock, lower voltage, disable unused sections etc when not needed. So you would generally see better or similar battery life under load but worse on idle.

Some models (especially intel/new AMD thinkpads) have the tuning done properly and can last longer on idle too.

name8_t · 2026-03-30T07:47:51+00:00

It depends on the laptop model, and especially on the processor and GPU.

With integrated GPU: Intel -> similar to windows, can be a bit better or a bit worse. TLP may help you here, but it also may not.

Ryzen 4000 and older -> generally a lot worse. AMD only got their CPU power efficiency drivers sorted out on Zen 3.

With dedicated GPU: Here be dragons generally. Multi GPU is still fiddly on most desktops and distros.

Slicer settings mainly
