  • What have you done to clean the bed?

    I cleaned it with water and dish soap. There’s nothing like it for adhesion. Even IPA doesn’t quite get the same results.

    Has the TPU been dried?

    I left it in the dryer at 55C for 3 days. The internal hygrometer says 13%, I tried drying it hotter than that, but then it seems to have trouble travelling through the silicone tube - like friction or something.

    What’s the max speed you’re printing at?

    Whatever the default is for the Prusa-supplied preset for this very filament brand and make. I just lowered the nozzle temperature to prevent stringing and material “balling up” on the surface, and I raised the bed temperature to increase adhesion a bit.

    In addition to a brim, have you tried adding supports?

    There is a ton of support for that part: it’s organic support and it’s growing inside and outside the part without ever touching the part itself. The reason being, it’s basically a thin bellows that’s two layers thick, so I don’t want anything supporting the bellows, or any support growing from the bellows, because it’s super-fragile and it won’t survive removing the support. That’s one of the reasons why we ordered a Prusa XL with 2 heads: one will extrude the part in TPU while the other will extrude the support in PLA, which should fall right off.

    So since I told the slicer to avoid touching the bellows with the support trees, there’s a lot of it going around it on the outside. And indeed the bits of parts that I managed to print so far seem quite stiff and nicely supported. But the problem is, the entire thing simply comes unstuck and flies off the bed when it becomes too heavy.










  • I’m all for MFA, but ultimately, a GOOD password - or rather, a good password recipe - that resides in my brain must be included in the mix as far as I’m concerned. Because unlike other forms of authentication, that one can never be extracted, stolen or recovered without torturing me.

    So you can have your passwordless future: I’ll keep my passwords - in combination with other forms of authentication of course. Passwordless is lesser security for the lazy.




  • They didn’t “clash” at the White House: Zelensky got a bona fide dressing down from the orange utan and the couch fucker, like a little kid who done something wrong, purely based on untruths and lies.

    If anything, the man should be praised for keeping his cool. Can you imaging being scolded by those two morons while your country has been at war for three fucking years and you have to endure the indignity to try and save it? If I had been Zelensky, I would have spat on them, gotten up and left.
