One of the biggest time wasters on prints requiring supports is the nozzle change. Is there any setting for doing mixed supports such that the only the first and last few layers are from nozzle2 (e.g. breakway) and the rest being from nozzle1 (e.g. PLA)? I force this behavior on some of my project like below by just making an extra part to fill that space:

Depending on the print size, this can save a bunch of time. In this example its a reduction of a little over 5 hours! I'm printing 8 of these, so 40 hours!

I feel someone likely already thought of this, but I'm not having any luck with my search keywords.

    Just change Support > Support Extruder > Support Infill Extruder to your first extruder.

    (I changed your first extruder to green PLA so you can see the difference)

    Thanks! Interesting that I still saved more time with my method, but I guess that depends on the support density. Also find it quite confusing that this is called infill where this means something totally different in the rest of the cura settings ¯\_(ツ)_/¯

    I think @Slashee_the_Cow meant Support Interface Extruder. Support Infill Extruder is also a thing, but not what's showing in the image.

    The file was originally set so that all support was being printed by the second extruder (white, printing breakaway). I changed the support infill to be printed by the first extruder (green PLA in my example) so it only needs to switch to the second for the interfaces.
