I know people who have 3D printers that are little more than appliances. They buy it, they print with it, and they don’t change much of anything. That doesn’t describe me and, I’m guessing, it doesn’t describe you either. This does lead to a problem, though, when it comes to slicers. You have to keep changing profiles and modifying them. It can be hard to keep things straight. For example, if you have profiles for different nozzles, you get to make a choice: keep one profile and edit the parts that change, or keep multiple profiles and any common changes have to be propagated to the other profiles.

I’ve long wanted to create a system that lets me have baseline profiles and then just use specific profiles that change a few items in the baseline. Turns out, I didn’t need to do it. Prusa Slicer and its fork, SuperSlicer, have the capability already. Both of these, of course, are based on Slic3r, but the scripting languages are different and what I’m doing does require G-code scripting. The problem is, this capability is not documented very well and the GUI doesn’t really support it directly, which requires a little sidestepping. I’ll show you how I have things set up and where the limitations are. If you want to try your hand at it, I highly suggest you backup your configuration directory or switch to a new one.
