I print in ABS and it's very rare for me to have adhesion problems. Last night I kept having the corners of a thin plate lift and that is just odd with my printing. Ends up when I designed the item I normally hit a button in my 3D software (Lightwave) that makes sure the object is flat on the Z axis, well I forgot to do that and my plate was 1 layer off the print bed, it still adhered well everywhere but the corners. Once I fixed that, no problems.
So it's just a reminder that problems can be caused by the simplest things we forget to check.
