Is it possible to create a topographic map of the glass build plate surface utilizing multiple locations, for example the 4 corners, the center of the bed and maybe a few other points utilizing Marlin so the first layer always goes down the same layer height everywhere?
Due to the large number of variables like material type, bed temperature, how much the x-axis dips down in the center of the bed, etc it is difficult to always get a good first layer the first time every time so I am looking to eliminate one of the major problematic variables, namely unequal height of the hot end from the bed all across the bed, by creating a topographic map that the hot end can follow to create a uniform first layer.
Any suggestions on how to do this? A probe? The TAZ Mini bed leveling technique? Can Marlin even create a topographical map from input data?
