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!

I wasn’t aware. I’ll look into this tomorrow. Thanks!

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 fly off the bed when it becomes too heavy.
- Comment on Trouble keeping a top-heavy TPE part on the bed 4 days ago:
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.
- Comment on Trouble keeping a top-heavy TPE part on the bed 5 days ago:
Thanks.
I tried lowering the speed (I can’t see any setting in 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.

- Comment on What is the minimum number of words needed to communicate 4 weeks ago:
I try to learn the following sentences in the language of a country I go to if I don’t know anything at all about that language:
- Hello, as polite as possible
- Goodbye, as polite as possible
- A beer please
- I’m sorry I don’t speak <language>: do you speak English?
I find this quite enough to strike up a conversation in most of the world. When people don’t automatically switch to English - perhaps because they don’t know it well enough - then I try another “universal” language like Spanish or French (universal mostly because of past colonialism, sadly). That implies speaking those languages of course.
If the locals won’t speak in English because of a prejudice against English (mostly French-speaking regions) I don’t even bother with the “I’m sorry…” bit.
If the locals are anti-Americans - very common, and getting more and more common - I affect a British accent. I wouldn’t fool a Brit for a New York minute but I’m convincing enough for a non-native English speaker to avoid being associated with the US.

- Comment on Why build for tomorrow when it's someone else's tomorrow? 4 weeks ago:
I’m from yesterday. When I was a kid in the 70’s, my tomorrow was the triumph of science, an evermore interconnected world of evermore educated people, the rule of individual rights and freedoms, the retreat of religion and magical thinking, fewer and fewer wars and the gradual end of poverty.
I’m very bitter today because somebody stole my future. But you can also argue that I, a man of yesterday, failed to shape the world of today too. We all failed.
If you’re a person of today, you need to work towards a better tomorrow right now. Because if you don’t, you’ll end up regretting not doing it later in life like I do.
