combining material types

[ultiarjan 1,168]

I just tested a (dual extrusion) combination of Refill recycled PET (245) and PLA (205), printed ok, but failed as the PET does not stick AT ALL on top of the PLA ... (on a flat layer) anyone knows which material combinations stick or don't stick ?  When mixing "side by side" and 20% overlap it's ok in this case.

FYI, the 2 headed UM2 setup:
