First Layer issues 

It could be that the print simply does not stick or you’re finding unwanted lines that cause the bottom shell to have an unexpected look. Additionally, it’s entirely possible for any fine detail on the bottom of your print to congeal into a blur with little semblance of any surface design.

What’s causing this 3D Printing Problem?

These 3D printing problems are typical signs that the print bed hasn’t been leveled properly. If the nozzle is too far away from the bed, the bottom surface often shows unwanted lines, and/or the first layer does not stick. If the nozzle is too close, blobs may be the result.

Troubleshooting:

1) Level the Print Bed

         Level the bed as per the instruction in the bed leveling topic. 

2)  Lower Bed Temperature

          Try knocking the bed temperature down by 5-degree increments, until you hit that sweet spot of adhesion, without loss of detail.
