Jato3d - I had the same problems. Turns out there were several causes, corrected with the help and advice of those here on this forum.
I was over-extruding. I needed to put in a more accurate diameter for the filament, and recalibrate the extruder using 40mm/min speed, rather than the 100mm/min recommended in the calibration guide (the lower speed corresponds more closely to the actual extrusion speed during printing). Fixing the overextrusion helped the prints release a little easier, and also cleaned up the surface and corners of my prints.
What does the surface of your first layer look like? Mine was a bit rough. There were “fins” of excess filament poking up parallel to the lines of print (where one line adjoined the next). Basically, I was dragging the nozzle through the extruded filament and smushing it down onto the print bed. Resetting the Z offset up a bit smoothed out the surface of the first layer dramatically, and also helped with part removal. It took a few tries to figure out how high to raise it, but for me, 0.1mm seemed to do it.
