Hi all 
New to 3d printing and the P1S is my first 3d printer. Very impressed so far, print quality has been top draw with no failures yet! 
I have one quick question. Today when printing the inserts to Jorge Rui Toolcase off Makerworld the first layer has a rough spot near the front of the bed but the rest of the first layer looks perfect! What causes this and how can it be rectified? Printing with eSUN PLA+
