Skew angle innacuracy (or maybe hidden math joke)

[bharrisau]

klipper/klippy/extras/skew_correction.py

Lines 93 to 95 in 49c0ad6

	factor = calc_skew_factor(ac, bd, ad)
	gcmd.respond_info("Calculated Skew: %.6f radians, %.2f degrees"
	% (factor, math.degrees(factor)))

So calc_skew_factor returns the tan of an angle - but the print statement is referring to it as the actual angle. Should probably be printing the arctan of the skew factor for correctness.

But if you apply the fundamental theorum of engineering - we know that sin(x) = tan(x) = x. So the actual printed values are still really close to the true angles.
