Multiple prime towers


Recommended Posts

Posted · Multiple prime towers

First off, Prime towers are AMAZING, and the way that Cura switches extruders for dual head prints is fantastic.

What about more heads? I run an E3D cyclops, which can be run as a rudementary mixing head, leading to my printer having 15 "extruder" settings, that can run customized mixes of filament. What I would love to have is the ability to tell Cura to run more than two of these "extruders" in a given print, and for it to use more than just the one prime tower (or maybe a different style of prime tower) for additional extruders.

I have noticed that when setting the printer to anything more than two extruders only the first two get primed, all the rest do not, meaning that mixes cannot become consistent.

I would use a purge location, but as my printer is a delta bot (Rostock Max) the extruder moves in three axes, so a single purge location is very much suboptimal, and I cannot figure out how to tell cura to select the "previous" "current" and "next" extruders in the before and after extruder switch gcode.

I have searched around trying to find a way to do this, but as my coding ability extends only a little bit past arduino and VBA I haven't been able to wrap my head around the slicing engine enough.
