  • I’m going to make the assumption that is PETG you are working with. I had cobwebs like that when I tried moving over from doing PLA. There were a few things I had to work out to get better prints.

    1. Slow down the print speed and work up once you get acceptable prints. Try 40 to 50mm/s to start.
    2. Increase filament retraction. Default I think is like 0.2mm, try 1.0mm instead.
    3. Increase the travel speed. I’ve used 350mm/s, which helps break strings, as someone else already suggested.
    4. Drop the extruder temperature. PETG gets more stringy as it gets hotter. Lower temp may help, and if you aren’t trying to print at warp speed, bonding should still be good. Do small test prints to see where your cutoff is. Also, if the cooling fan on that Sovol is a bit anemic then printing cooler lets each layer solidify before the next one gets added. Hopefully you get things worked out, good luck.



  • Not a laptop, but I had an old motherboard from over 20 years ago not doing anything. Screwed it to a board on the wall of my shop. Added an old hard drive and some components out of the same old box it was in, and now have it running Mint. Found an old wifi card that works too, so I can look up parts and repair videos while I’m working on projects. Works great.










  • I’d played Doom with people on networked computers in college, but that wasn’t really “internet”. But right at the end of the 90’s when we started getting online game servers was great. Being able to play Unreal or Battlefield 1942 with random people from anywhere was amazing, and very addicting. Servers would have like 8 or maybe 16 player slots. More than that and lag would make the games unplayable. You’d keep refreshing the server lists looking for an open slot with a low ping, and join in. Actual early internet wasn’t terribly exciting. Pretty much just text only, maybe some tiny graphics, since download speeds were unbearably slow.
