What are purge lines for? Why can’t the slicers just leave them out? Can they be edited out manually in the code file?

    The point of purge lines is to make sure that the nozzle is properly filled with molten plastic, and that there’s nothing stuck in it.

    If you’re printing with a skirt or brim, you can probably print fine without purge lines. If not, there’s a chance that your first layer starts off with a defect.

    If you really want to remove it, your slicer should have a Start G-Code section that is added to every print. If you know what you’re doing, you could edit part of that out.
