Bumps in first layer

[gerycruz 0]

Hi everyone I've been seeing this issue on and off, it's more common with larger, square-ish prints...

I've tried increasing or decreasing speed, bed and nozzle temperature but I can't seem to nail down the cause.  When I examine the skirt I get a nice squished flat line so I'm not sure it's bed alignment.

Thanks!

When the nozzle it's too close to the bed it makes that effect because some filament get's pull up by the nozzle. So, it's just a bit too close (tiny little bit).
