Pla Peeling
Not sure whats going on here, here are my specs and the things I have tried
Prusa i3 printer with a marlin board
200c ,212c & 220c hot end
60c bed temp
Kapton tape & painters tape
Bed is def level and paper thin close
If the printer has to make long strokes the PLA will peel up like shown in the attached picture.
The picture shows the 3rd layer of a raft.
If I print the item without a raft it does just fine.Pla Peeling
It would appear it only happens on long travel distances.
Any help?

Hi Tim,

Welcome to CW forum.
Please try it with another filament, to close out what can be bad.

That looks like contraction due to cooling to me. I print PLA at 185 degrees on an unheated bed and don't have much trouble with contraction unless the part has a very large contact area with the print bed.

AFIK the bed is a little to far from the nozzle.
