Had issues with bed adhesion, this and a bed temp adjustment made all the difference. Its nice not having to bed level after every print. I print on a glass bed so a temperature adjustment to insure the glass was at the right temperature was needed, this first adjustment help adhesion a bit better but the bed leveler was the final solution. The glass is not perfect but that no longer matters as the bed leveler checks 9 points and adjusts the Z axes to follow the bed based on the points, very cool!!
