Bed Level Calibration Ruler

thingiverse

A simple comprehensive ruler to check your build platform leveling. I use this to get a really finely adjusted surface for my prints. Instructions: Scale the model in your slicer software to your layer height Set first layer height to 100% Print Let build platform cool and carefully peel the print up Using calipers, measure across the 3 circular areas. On my Powerspec Ultra 3d these correspond to the locations of the set screws for my platform. These should all be with +/- .03mm of your layer height and no more than +/- .05mm from each other. If necessary, adjust the set screw beneath that circular area by 1/8th turn, and go back to step 3 Otherwise, check the infill consistency throughout the print, it should be consistent across the entire print. Inconsistencies will be most apparent opposite the set screws. If there are inconsistencies and they are opposite to a set screw, adjust the 2 set screws closest to that corner by 1/4th turn, and go back to step 3 Otherwise your bed should be level to within +/- .05mm!
