He's in Wisconsin eating his cheese hat at the moment.

More accurately phrased: See which countries US importers are going to have to pass the cost of importing from to US consumers the most.

I'm guessing the price of eggs won't go down all that much after all...

Trump said the US would charge half of the fees he feels trading partners unfairly impose on the US

on US citizens, is what he left off.

Well, you experienced the rise of fascism 1933-Germany-stylee, and now here's your chance to experience the Great Depression of 1929. The second Trump presidency is in fact a living history lesson.

The stupid thermometer has just exploded. Those fucking idiots Heritage Foundation and the orange utan have just triggered a new worldwide great depression...

Hey Americans: how about you use that 2nd amendment of yours you keep bringing up for what it was originally intended for for a change?

True enough...

It says something about the state of the nation when the only recourse against fascism is something this pointless. But I admire the effort and I understand the symbolism of the gesture. Congrat Cory Booker!

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 flies off the bed when it becomes too heavy.
