Hi, I am very new in this forum and hope that your expertise can solve my problem.

First of all: sorry for my poor english.

I am trying to print a part from TPE ( Also TPU). at the end of the Print ( after almost 11 hours) the surface below the ( Trees style) supports gets some irregularities.

I also tryed the classic support but unfortinutely the problem did not dissapear. This is how it starts:

The Black Filament is TPE (Filaflex). I tried already a lot and i am still not happy with the results.

Maybe I should reduce the distance betweenthe supports and the model? So many Parameters??

Thank you for your help.
