The bed is \"level\" across the entire surface to better than 0.025mm, the measurement limit of my dial gauge.\r\n\r\nThe solution rides on top of the AUTO_BED_LEVELING feature and does not add a lot of code. If the auto bed levelling probes four or more points there is enough information available to solve the problem. \r\n\r\nHow is it best to submit this new feature? Could someone explain how to create a git pull request. Is their a guide for submitting pull requests that I missed?"}}
