TPE warping problems I'm attempting to print some flexible TPE filament. But I failed to imagine TPE was this difficult to print.

Specs of the shop-brand filament:
Red 1.75&nbsp;mm TPE (+-0.05&nbsp;mm).
Hardness: 45D.
Print temperature: 220-260&nbsp;&deg;C with 0-95&nbsp;&deg;C bed.

I'm trying to print this on my original Prusa i3 MK3S with powder coated sheet with 0.20&nbsp;mm layer with PrusaSlicer 2.0.0.

What happens? After 3 or 4 layers, the print warps a lot and detaches from the plate. The object is 40&nbsp;mm long. The next image shows the print detaching from the build plate as well as a skirt of two layers height:



I've tried warmer/colder, more/less fan, faster/slower. I went down to 1&nbsp;mm3/s, which is 7&nbsp;mm/s. For reference, PLA prints 15&nbsp;mm3/s.

I readjusted my z-cal, and when I test print a first layer with TPE it's difficult to remove from the bed.

I also attempted the glue stick on smooth PEI sheet. Worked until the first few layers of infill, then it still warped.

Do I have bad filament with too much shrink, poor settings or is this 45D just too soft for my MK3s? 

Bonus pile of failures:
I have not given up yet!

And I figured it out, I think. I tried many things, dried the spool at 60C for an hour, Simplifiy3D's slicer, but eventually playing around I found a setting that resulting in no warping during the print.

Final solution:
- Original Prusa Powder Coated sheet.
- Changed the nozzle to 0.6 mm.
- 20 mm/s print speed, slow.
- 260 C nozzle temp, make it liquid to get best bed adhesion.
- 90 C bed, this keeps it soft at the bottom. Do not change the temperature, as this will detach the print.
- 0.95 Extrusion Multiplier instead of 1.2  

The extrusion multiplier did the trick. It kept pushing slightly too much stuff out, especially on the bottom layers causing ridges that is will pull on the next layer.
It did still warp a bit, I found that this stuff shrinks about 2% when cooled, and when you start infill, it will pull itself loose. Hence the 90C bed temp.



It still prints poorly, but it did print without creating "the blob"!
