Note that using G10/11 won't handle "wipe during retraction" option in S3D.
I'll suggest you to use this model : https://www.thingiverse.com/thing:909901
Add it X times in S3d and customize each process with different retraction settings. (Don't forget to print with piece by piece option with enough clearance) the model is small it'll be easy.
At least you'll end up with a clean base to fine tune reactions with more complex models.
