I would like to load two different color PETG filaments in the left and right extruders and select what layer to change from one to the other in Luban. Has this ever been implemented? I’ve looked for “color change” and found several discussions and posts about the M600 command but those were all concerned with a single extruder. Thanks, ---

Just paint it, Icon on the far left below the support icon, be careful though the additives in different formulas of filament types even within the same brands don’t play together nicely all the time ![Screenshot 2023-09-16 142255](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/3/c/3cde46f23a88c901d932987e97b8fc28b93ff016.png) ---

I didn’t realize that’s what that thing was for. Thanks!
