Is there someone that know the mathematics behind the MeshBedLevel points.
I have a “semi working” piece of software that uses the probe to meassure the points that MBL do in the manual procedure.
The X1 Y1 have a Z value of 13.85
The meassured Z value is -2.40 and I know that the Z_PROBE_OFFSET should be 2.40mm ( found with a paper under nozzle).
To transform this 0 ( 2.4 + -2.4 = 0) to the 13.85 I need the mathematics behind how the manual procedure created that value.
When I have the probe-meassured values transformed with the mathematics of the manual MBL I will update the MBL point with
G29 S3 Xn Yn 13.87 ( = the probe meassured value is 0.02mm more accurate than the “feel-the-friction-on-a-paper” method)
This is the last part in Marlin3DprinterTool that I think really will increase performance on the first layer.
