We do plan to share as much detail as we can with the community. We've started with a silicone how-to, http://forum.structur3d.io/t/get-past3d-ep-1-3d-printing-silicone-part-1/208
Much of the information is similar for Nutella, with possibly some slight reduction in the motor settings (i.e., slightly slower speed).
Each printer is also slightly different when it comes to the settings with the Discov3ry. The motor settings (EEPROM or extrusion/print speed) for the Felix 3.0 are different than what we use for the Ultimaker 2 -- same material and same Discov3ry. So there will be some amount of optimization needed for now.
As our community starts using the Discov3ry, we hope they will share the details of their settings -- that way, eventually, a much larger assortment of ready-to-go printer settings will be here on our forum.
