Ian Rommies issue is that the Effector tilt causes the probe to trigger at differing height around the bed and unfortunately this negates the use of the Bed Comp anyway and the prob will be just the same with a BLTouch.
I think DJ's Piezo idea will do away with that error as it uses the Nozzle tip itself as the probe point.
I wonder how difficult it would be to use Strain gauges on a
CB material or even better a Carbon Fibre effector with a set of Hayden's rod's?
