  • My 4 last employers have used desktop Linux to some extent:

    • Ericsson (Swedish telecoms), default was to have a Windows laptop with X server (Citrix?) but a few of us were lucky enough to get a Linux laptop.
    • Vector (German automotive), Linux dev. environment in a VM on Windows laptops.
    • Opera Software (Norwegian web browser), first day I was given a stack of components and told to assemble my PC and then install my Linux distribution of choice.
    • And a smaller company, which shall remain unnamed, also used Windows laptops with Linux dev. env. in VM.

    Sure most of it was on top of Windows, but if you fullscreen it you can barely tell the difference :)


  • It sounds like bed adhesion might have got worse, perhaps you have touched the print surface with your fingers while removing prints? You could try removing the plate and washing it with warm water and soap. Some people use IPA but if you do then you need to make sure you really wipe it clean before it evaporates, otherwise the dissolved fats will stay on the bed. If your bed has some kind of anti-stick coating I think there’s also a risk that you damage if you use stronger solvents.

    As for warping in general it could be an indication that your flow rate is exceeding your melting capacity. If you have an all metal hotend you could try printing at higher temp, if not then try reducing print speed instead.


  • My first couple of computers had AmigaOS and even from the start Windows felt like complete garbage in comparison, but eventually I had to buy a PC to keep up with the times. After that I kept looking for alternative OS:es, tried Linux dual booting but kept going back to Windows since all the programs and hardware I needed to use required it. When I finally decided to go full time Linux, some time between 2005 and 2010, it was because I felt like I was just wasting my life in front of the computer every day. With Windows it was too easy to fire up some game when I had nothing else to do, and at that time there were barely any games for Linux so it removed that temptation. But that has ofc. changed now and pretty much all Windows games work equally well on Linux :)


  • Ahh, I thought you meant you had a 0.2mm nozzle, but now I see you probably meant layer height.

    Moisture absorbtion is rarely a problem with PLA, but hopefully dehydration won’t hurt, as long as you don’t accidentally overheat it and it deforms. I’ve left rolls of PLA out in the open for 6 months without noticing any deterioration. Both your filaments used to print fine, and then the oozing spontaneously started with both of them?

    2mm retraction should be more than enough for a direct drive extruder.



  • What filament and other slicer settings? Could be too hot. Could be retraction settings. Did the oozing start when you switched nozzles? If it’s a cheap Amazon nozzle it might be faulty and have a different diameter than advertised. Did you follow the correct procedure with hot tightening when switching nozzles? If not, you might have got molten filament in between the nozzle and the heat break.





  • It’s not easy trying to research which 3d printer to buy, there is more click bait and marketing than impartial reviews out there, and search engines tend to promote the garbage. And without a lot of 3d printing experience, it can be difficult to know if a “review” is paid for by the printer’s manufacturer, or just trying to trick you into clicking their affiliate links. There are also no consistently good brands if you’re looking for a cheap printer, pretty much all of them have produced a few good printers and others that have more flaws. For example old Ender 3 and Ender 3 Pro were very good at the time, and Creality built up a lot of brand recognition, but then they switched to low quality components and seemingly stopped doing quality control and made a bunch of crap. Now it might be turning around again, as Creality’s latest printers are starting to look decent again, although perhaps a little overpriced.

    Personally I use this spreadsheet to compare pros and cons of budget printers. It’s maintained by a group of users at a 3d printing discord server, and while one cannot know for sure none of them have any ties for example to Sovol (the most recommended budget brand currently), they’ve seemed quite impartial to me so far.
