1st time flex on powder coated sheet, print doesn't stick

hi,

 

I  tried to print my first phone case. and it did not go so well.

as long as the flat part was printing, it went very well. but once the flat part was finished and the sidewalls started to print, 2 corners started to detach from the sheet and began to curl upwards.

at one point, the super-pinda sensor caught the print and began to peel it of the sheet as the head was progressing.

this was the moment when I had to stop the print.

I did sheet preparation as instructed (clean/degrease it with IPA), filament is fillamentum flexfill TPU 98A "natural", I chose the corresponding settings in prusa-slicer.

what shall I try to prevent this? raise bed temperature? 

 

 

Best Answer by remington:

from smooth to textured i have to increase the z offset from -.700 to -.900.

perhaps this is part of it, but also, try printing it with a 5line brim to the print, it should help keep it attached
