Personally, my brain manages to filter out anything with a leading underscore (I don’t know the origin offhand, I think some system I worked with at some point used those on files that I knew I didn’t care about). So when coworkers use leading underscores it slows me down a bit.
It does work though
I have an MK4+MMU that I bought partially with the intent of building PLA-supported PETG and TPU parts. I haven’t dug in too far yet but in the few prints I’ve done the PLA has severely degraded interlayer adhesion. Presumably this can be addressed by purging (much) more on changes from PLA, but if I had known this before I bought, I would have seriously considered a multi-head printer.
