Filament preset change with M600 (using 2 or more existing filament presets)  

Filament preset change with M600 (using 2 or more existing filament presets)

If I'm printing a part with a PLA preset (eSun, for example) and want to finish the last ten layers with a different PLA preset (Prusament)...how is this accomplished? M600 assumes you're changing the color of a filament with the same diameter and flow properties (which is a big assumption).

In my case, I've tuned the presets since the filament diameter and extrusion multiplier are different, and I want to see these parameters show up in the actual part.

So far, I've had to run the slicer with both filament presets and a color change event (M600), then in an editor, I manually copy and paste the first half of one filament and the second half of the other filament into the same G-code. I was hoping for an in-slicer method.

Thanks.
