How do I solve this ripple?

I've been trying to chase this issue for a long time now. I can't seem to find a solution. It always happens on the first layer. I've tried using Elmers school glue, aqua net and ABS juice on my glass bed and nothing seems to work for this issue.

I've been using hairspray to help keep my prints sticking to the bed. It's been working wonderfully. Also check the temperature of your heated bed. It's possible that you have it set too high.

Jaeg was close, for me, what worked (with PLA) was raising the temp to 60º for the first layer and 50º for the rest. Also, layer height solved a lot, but the z-endstop looks correctly configured for your printer.

I had this rippling a lot on glass to I put an aluminum sheet with kapton on it instead of glass and now my prints couldn't be better!
