I searched online and found some posts around on other sites that are a few years old, but nothing recent. There was lots of talk about how to prevent jamming and stringing in side of the Y.
I am printing PETG, so stringing is definitely a concern/possibility.
I am not doing fancy multi-layer work, really I just need to change colors once per print at a given layer. The Y just saves me from having to get to the printer to do it by hand

Any tips on what scripts/settings to put where to let this Y work?
