Improvements of multi-material printing
For a long time, a community-developed feature exists which claims to improve filament tips during toolchange sequences, which would in turn increase reliability of devices depending on reasonable tip shape (such as Prusa MMU1 and MMU2). This feature is referred to as "skinnydip", and the basic principle is to push the filament back into the melt zone after it was unloaded to melt off the thin string that the filament often has. We at Prusa Research have tested the feature several times, but the results were not very convincing and we never integrated the feature into PrusaSlicer. After doing more experiments recently, we found out that the technique is more convincing when preceded by very rapid ramming.
Based on that knowledge, we decided to implement very similar approach for reshaping the filament tip. Because the goal is to reshape the filament tip using the mostly empty nozzle, instead of melting off the thin filament tip, we call our approach "stamping". There are two new parameters in Filament Settings (filament_stamping_distance and filament_stamping_loading_speed) which control how far and how fast should the filament be pushed after the initial unload. The stamping moves are coupled with cooling - the stamping moves are performed between the individual cooling moves.
