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!
