I am also seeking a solution for use w/ my A2v4. I am struggling most with priming the extruders - I inserted some priming commands in the start g-code for each extruder that mimic Cura's "prime blob" feature (which is disabled for this printer). While that worked well for basic single extruder prints, it is not feasible for multi-material prints that switch back and forth between extruders because a 'blob' prints each time.

4.5 Mac will not open on my MacBook Pro running Catalina. Here is the message.
