Anyone has some decent profile settings for TPU?

[FraggleRock 5]

I currently have a couple of soft 3mm TPU filaments from Matterhackers and SainSmart.

I spent half a day trying to figure the one from Matterhackers. I was able to print some small 20mm domes that were somewhat acceptable although very fuzzy and also cloudy (it's a clear filament)

Then I tried to print a slightly larger model, and it failed spectacularly. Basically stopped extruding.

I don't know what's going on, but to save my sanity I thought I ask if any of you have been successful in printing with TPU. I'm using an UM3.

Thanks.

 

Also a side note: The default hardware profile for TPU on the printer is at 220 degrees extrusion, and the TPU I got recommends 240-260. So If I try to move some material on the printer to check the extrusion, it is not possible cause the temperature drops back to 220 degrees (from the printer profile)  when I move the menu choice from "printcore temperature" to "move material" option. I'm honestly irritated that these factory settings can't be overwritten as an option.

Hi,

 

I've good results using Ultimaker TPU (on an UM3, original feeders) and standard settings. Although it's a little bit stringy (especially at inner walls), the printing results are acceptable. So you could try duplicating the TPU profile and eventually change the temperature settings in that new profile.
