We've had some adhesion problems in the past, but recently this seems to be solved by recalibrating the platform (+half a turn closer). The current problem is with the first layers after the raft (as can be seen in the 2nd pic). Here the surface is very bad, it seems like the surface has cracks that open.
Guess the learning will never end;-)
So if I understand correctly it's essentially the first layer that is causing problems where it seems you have bad adhesion to the bed, right? I actually had that same issue with regular PLA where it turned out that I had to perform some proper bed leveling. If the nozzle is little too far from the bed, it will not stick well. Just a suggestion, I'm still learning myself :-)
