When printing large flat surfaces, the surface starts to separate into strips. The surface looks good near the edges but gets worse as you move toward the center of the surface. The attached pic shows an extreme case from a test piece I made where some of the strips completely pulled away from the surface. They usually just leave a rippled effect on the surface which can also be seen. I appreciate any help.
thanks

That usually means that you still need to adjust your bed level/position a bit more. If it's looking like separate lines that aren't sticking, then that corner of the bed is probably too low (the nozzle is too far away).

When each layer is only around 0.1-0.3mm thick, it's very easy to see these slight position problems
