    That’s so strange, I have no problems printing PETG all the time.

    Yeah, I don’t know - I’ve never had any big issues in the past with it either (I mostly print PLA+ though, unless I need something more heat-resistant for my car or outdoor use).

    This particular issue was with an Ender 3 V2 running a BLTouch and an aftermarket textured PEI sheet in an enclosure - so there were no drafts or anything that would explain the bad adhesion either. Just scrubbed it with some water and dish soap. That was literally the only thing I messed with between the spaghetti result run and a great first layer run, so I figured I’d mention it in case it might help OP.

    I’m exclusively using textured PEI surfaces on my printers, and I can strongly recommend them as well. That’s why it was so surprising to see PETG refusing to stick, even though my first layer with PLA was having no issues at all.

    I mostly print PLA, and I was just done doing maintenance on the frame and doing some calibration, etc. Everything was dialed in - the only thing I didn’t bother with was the bed because I had no issues with PLA.
    Literally, the only change between PETG spaghetti and a great first layer was cleaning the bed.

    I was pulling my hair out over poor bed adhesion with PETG while I was having no issues with PLA. As in, completely failing a first layer test with PETG turning into spaghetti while PLA printed perfectly.
    Turns out that PETG seems to be more sensitive when it comes to how clean the bed is. Scrubbed the bed with water and dish soap and the same gcode that was producing spaghetti was now printing without any issues.


  • I wonder what it is that is keeping more diverse users away?

    One aspect is that federation is definitely a bit harder to wrap your head around technically.

    But I think another large contributor is the fact that culturally, the zoomers never really grew up with things like independent forums. I’m 33 and back in t the day it was very common for me to be signed up to many different forums for my different interests. Over time, I’ve seen the centralization of those communities, forums shut down and centralized services like Reddit, and lately Discord took their place.
    I remember a time when the internet wasn’t solely controlled by a handful of organisations, I can see the value in federated systems. But someone who only knows centralized services and walled gardens is likely to fear the wild, or at least won’t value it as much.

    //edit: Another thing to keep in mind, is that it’s just very common for this demographic to be early adopters for tech products and platforms. I remember when Twitter started, and a large part of its early user base was people in their 30s or older who were very into tech, or journalists. The reason I started using Twitter towards the end of the 2000s was because most of the podcast hosts and regular contributors on the TWiT network were using it.
    Seems to me that if you want to launch a social media platform, your early adopters are either guys who are into tech and in their 30s and 40s or teenage girls.







  • Unless I’m actively looking for a specific type of application, or to replace one I already run, I just check in on the subreddit periodically, just looking at the top posts from the past month or so.
    I guess I’ll start checking in on lemmy now.

    There was a time, where I was checking for new stuff to selfhost almost daily. But at this point, I have what I want, and there is no point in trying to change a running system.
