I just started using different colors at certain levels, but it doesn’t act the same way as it did when I had my Ender3 S1.
I’m using Orca slicer.
On the 3V3+ the machine only pauses and I must go through the menus, to retract, extrude and then proceed.
On the S1, it would stop with a change filament message, and as I remember, to retract, all I needed to do was hit the button that was offered, replace the filament, then hit continue and it would resume printing with the new color after it purged itself.
On both machines it was just a M600 command if you checked the G code.
Seems like it’s a difference between Marlin, which was on the old machine and Kipper which is on the new one.
Is there some more code that I could use to automate level changes a little further?
