PETG and supports

Hi folks,
I've been using petg for a while now and love it.
But i still haven't been aable to generate supports in either slic3r or kisslicer
that seperate as easily as abs or pla. Usually it is the top horizontal or
near horizontal surfaces that are glued to the model.

Has anyone come up with settings for slic3r or kisslicer that lets petg
supports come away easily?


Many thanks,
Andrew

I use Simplify 3D with PETG and the supports were no harder to remove than for PLA. So it's not inherent to the PETG.

Umm,
Thanks for that. I had been wondering if it is a slicer issue.

Do you use a bed fan?

No part fan.

think that s3d uses 2 empty layers between interface material and the part by defaut if that helps any

Appreciate the help everyone.
I think I might have to give up on kisslicer and slic3r and buy simplify3d.
I've stepped the z spacing in kisslicer from 0.2mm to 1.2mm and seen no difference.
I've changed the extrusion factor for the support down to 0.4. No difference but
it seems to affect the extrusion factor for the main model.

Very frustrating. If I could get the supports to work I'd be using PETG only.
