Wow, what a fool I feel I am asking this question.
I’ve done this before but can not remember how to stop a print at a specific layer in order to change the filament to another color and then resume the print.
I’d bookmark it, then make a note to remind myself that I bookmarked it, then a week later I’d forget I did that. Old brain no worky. It’s a good thing I can search my hard drive, my email and the internet, because if I can’t find it by searching, I’m lost. I have an advanced case of CRS.
