Is PROBE_CALIBRATE primarily intended for printers that don't use TAP?
TAP can determine the z_offset within a micron according to PROBE_ACCURACY but yet it doesn't save this information to .cfg, why not?
I'm confused, if we take the average of -0.475250 from code above, and add the paper thickness 0.075 (measured using PROBE_ACCURACY with paper in place and then subtracting the averages), we get -0.400275 pretty close to what the paper method returns, in my case z_offset = -0.405...
I should be able to put the following in my probe.cfg right?

Code:
#probe accuracy results: maximum -0.475000, minimum -0.476250, range 0.001250, average -0.475250, median -0.475000, standard deviation 0.000500 no paper cold
