Simplify3D support doesn't come off

Has someone found working settings for the support generation in S3D?

Whenever I print (large) flat surfaces based on support structures they are basically impossible to remove.

I can print the same object, with the same material at the same temperature with Cetus's slicer and the support peals right off.

Here are my current settings although I already experimented with different values - without luck.


I tried reproducing Cetus's support as accurate as possible.

Please help me out if you know a solution.

Increase Upper Vertical Separation Layers to 1

Just to expand on that, you can reduce the horizontal offset a bit, I think I keep mine at .5mm 

If you are printing something with supports that start on top of parts of your print rather than just on the raft, also increase the Lower Vertical Seperation Layer to 1
