It’s not clogged: I fished out the mangled piece of TPU and printed something else with it straightaway - several times. Not sure why it starts clicking like that with that filament. Worse: it seems to do it almost always at the same point in that print.
I applied some glue to the sheet and it didn’t increase the adhesion by much, but it increased it enough and the print went through okay:
However, now I have another problem: I tried to print another one with the same material and the head started to make clicking noises mid-print and stopped flowing 😢 I’m not sure what’s going on with this now. Maybe I need to raise the temperature or something.
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.
It’s heavy on both sides. Also, I need to keep this thin wall facing up because otherwise it would be essentially impossible to remove from the support. And I need the bits facing up to be very clean, while I can afford some nastiness on the bit that faces down after I’m done removing and cleaning the supports.
I added a giant brim all around the part (connected to the part). The whole thing - part, brim and all - simply comes unstuck.
Thanks.
I tried lowering the speed (I can’t see any settings to limit it in only one axis though) but from what I read is safest for TPU / TPE, it turns a 2-hour print into a 2-day affair. Not an option for a printer that’s used by everybody in the company all the time.
how about they leave the fluoride in it for starters?
Mistreating disabled people is the prerogative of the state now that the US is fully fascist. The DOJ is investigating because the state doesn’t like competition.
Remember, it’s an Elon Musk gig. He easily confuses billions and millions on his DOGE website.
My guess is, Tesla in fact sold 8.669 vehicles this weekend - i.e. eight new cars and 0.669 car’s worth of spare parts.
It’s so easy to mistakenly type a comma when you meant a period…
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.
The only way she would care about labor is if she was pregnant…
And you know it’s AI slop because Musk has two left feet.
AI…

Dumb Fox News bimbo needs to keep her trap shut.
Worth noting: rare breeds tend to be weaker, less adapted to their environment and disappear easily.
That’s why they’re rare.
Hmm, RFK Jr. looks a lot browner than I remember him from last week…
He is much too verbose, launches into side topics that have nothing to do with the subject on hand, and he speaks much too fast. But that’s his style. I believe he’s on the spectrum and doesn’t really know how to focus on what he has to say.
Having said that. I think Louis Rossmann wouldn’t be Louis Rossmann, or even be as efficient as he is, if he didn’t do that.
You were right: after some trial and error, I backed off both idler tensioning screws 2 full turns and then the print went without a hitch. It looks cleaner too. And I don’t know if it’s related (now sure how it would be, but who knows…) the part didn’t warp. First time I get a complete straight TPU part.
Thanks for the tip!
