  • My mother lost her shop because she was selling charms (on bracelets she made) that had copyrighted/trademarked designs that she bought from China. She didn’t produce the actual infringing part, just partnered it with her own stuff. She still lost her shop after a few strikes.

    I assure you that Etsy is serious about that, but it takes a few reports to actually shut the shop down. If nobody else is reporting them, it could take forever.

    Go ahead and report them. If they’re really bad about this, they’ll lose their shop immediately. Otherwise, it’s a very strong warning.

    Edit: Also, if you really don’t mind them printing it, but want credit, release it under an appropriate license that states that. Otherwise, you’re only helping unethical people and preventing ethical people from doing it.

    When I’ve had something like that (or just underextrusion randomly part way through a print) I’ve decided it was a clog and did a “cold pull” on the filament to fix it and it seemed to work. It can be insidious because it sometimes clog and sometimes doesn’t.

    Though, I’ve also had people suggest it was “heat creep” where the heat gets too far upwards and melts the filament too early.

    I tried a never-used nozzle with no difference.

    The bed hasn’t been cleaned in a while, but the parts that aren’t underextruded stick very hard. And it happens the same in every place on the bed (I’ve tried about 8 now, always with the same pattern) and 2 different beds.

    I’m still thinking it’s a pressure issue, where it initially doesn’t have enough pressure for some reason. But I turned up the KAMP purge flow and it made no difference, and extruding 2 skirt lines made no difference that I could tell.

    My next step is going to give the bed a good cleaning… And even try the other side that I’m pretty sure I’ve never used yet.

    I’m printing ASA at 30/50mm/s right now, and I’ve halved the pressure advance value without any noticeable change. I agree with looks like pressure advance, though. I’ll try a really slow print soon and see if that matters.

    Printing PLA at 120mm/s had it show very lightly, but it’s still there.

    I’ve tried it on a textured PEI (ASA) sheet in multiple spots, and a smooth PEO (PLA) sheet, same results. It’s always the same size and orientation, thought the PLA one was a lot harder to see.

    The plate isn’t that clean, and I’ve used a lot of 3DLAC on it. I’ll likely try cleaning it again soon out of desperation, but I can’t see it being likely to change anything.

    I’ve tuned basically everything, and changing my pressure advance value made no difference. 105 bed, 245 hot end for ASA. 60/220 for PLA.
