Im just using PLA and the bed is Kapton tape, I think I've got a handle on the detachment issues, but the artifacts are a real pain, particularly when printining a part that has multiple colours per level.... heres what I mean

You see the cones are great, but the cube which prints great in single colour just looks really bad in multi colour even after I fettle it.... the failed print on the left shows what it looks like before fettling.
I may try it again with cooler extruder temps and increase the extruder retracts at colour change... maybe slow the print speed a little too
