An awful lot of problems can be traced back to a badly calibrated bed. your problem is definitely one of them.
Meaning the bed isn't level across? I did the calibration and it works flawless on the standard prints it's just when the get better and tends to be only on 1 spot of the bed. Should I check that side?
