bed level on the fly print pattern

Use the STL for the nozzle size you have installed or create your own custom file with openSCAD. I always carry these gCode files on my SD cards, anytime I want to check my bed level I just print the corresponding file and adjust the screws as needed to get perfect plastic. It will print a zig zag pattern from front to back twice so: 1. Begin by checking the front two thumb screws and make sure you're getting a flat topped line of plastic that is not too thin and sticking to the bed. 2. As it works its way back, check the rear area. 3. If the bed is close, simply cancel the print after the first pass and proceed to the back. If the bed needs significant adjustment, let the print come back to the front and remove all the plastic before it continues to the back again.
