PLA bubbling in the first layer of a print
Oh wow. You are way over cooking your PLA. It is bubbling because it is BOILING. I can tell you have it too hot because the lines are all blurred as if they are liquid and pooled together. 

That said I can't give you details because you didn't post settings. I would start by turning the temps to 170&nbsp;&deg;C for hotend and 60&nbsp;&deg;C for plate. Also the gluestick it self should never bubble. It is unclear if that is an issue..
