Problems with removing support structure (PETG, picture attached)

Problems with removing support structure (PETG, picture attached)  

New Member

Hello Prusa community,

I'm quite new to printing, but so far my prints are running quite well. I have just one problem, which I couldn't solve by myself so far:

For the part I'm printing at the moment, I need to place support structure on the part itself. The Slicer puts two layers between the part and the support structure by default, which I find nearly impossible to remove. Any suggestions how to print the support and the removing it easier?

Thanks a lot

Check the Z separation. Prusa Slicer defaults to .1, which is for soluble supports.

Change it to .2 (removable). And leave a little gap between X Y pieces. Only support overhead.

It will always be hard to get perfectly clean separation...

I use no interface layers when supporting flat surfaces, and set contact Z to 0.01 mm (zero dot zero one).  This allows direct support and minimizes bridging droop and creates a flat underside.  I also adjust support spacing and angle to best support the direction of the bridging filament - 2 mm is sometimes too close together. This part I used 3.9 mm spacing.

It is always wise to get more than one opinion......

I printed [this]( ) with 0.4mm Contact Z distance and the result was perfection.

I'm not sure why 0.1 is the default, I mean, by default not everyone is trying soluble support from the begging, at least should be a warning in the app.
