Hey all (first post here!),
I have implemented a continuous mesh probing algorithm for inductive and other non-contact binary probes: first, the probe hysteresis is measured with a few up/down movements, and then, the bed mesh is scanned with a standard serpentine motion. During the motion, toolhead zig-zags along the Z axis, creating a number of on and off trigger points along the path. At the end, a constant mesh grid is interpolated from the trigger point location data. The results seem to be accurate and highly repeatable. See the video below.
EDIT: Uploaded a wrong video, fixed the Youtube link.
