Someone may have already posted this but if not here goes...
Built in support (beyond scripts and work around) for the use of the new version of Prusa Multi Material version 2. To users and Simplify 3d supports credit there are some scripts and work around approaches to extend the multi-extruder capabilities already in Simplify 3d. The Prusa approach requires unload/switch/load in addition to heat/cool and purge steps. As the complexity of multi-material increases it would be helpful if there was a wizard or module that can be used to initiate multi-material printing. The basics have already been implemented for multi-material I think its just a matter of more deliberate implementation into the software and operation.
Prusa users with the MMU 2.0 need to prod Prusa via their support dest to share and participate with Simplify 3d the necessary parameters, protocols etc the Simplify3d developers need to do this right.
