The good news is the points seems to be taken in the "right" order now.
But the toolhead connected to the U motor needs to be active while the mesh is running for the U axis to move.
Which was not needed for RRF3.6.0-rc1 and before.
The points are being recorded in the right order in the heightmap file.

But the Klicky triggering was not detected again about midway through the second mesh calibration breaking it.

@dwuk3d this particular bug was new in 3.6.0-rc.1.

Programming Z probes connected to expansion boards is not yet supported. For now you need to temporarily connect the Smart Effector to the main board if you want to change its sensitivity. I've logged this issue: https://github.com/Duet3D/RepRapFirmware/issues/815

dc42 created this issue in Duet3D/RepRapFirmware open Support programming Smart Effector sensitivity when the effector is connected to an expansion board #815

@Cognirit we've also integrated the scanning Z probe into our new Revo Roto Tool Board.

@o_lampe said in "Cat whiskers" sensor as Z-probe?:

@arhi
It only makes sense to spend more money than a BLTouch would cost, when the result is equal or better.

To me it would make sense investing time if it would solve a problem that exist and is not solved. TBH I don't see what unsolved problem this could solve except to work as underbed probe. ATTM I don't know of reliable underbed probe. Probing from the top, I doubt it can have smaller footprint than some piezo/bltouch/easytouch/.. sensor .. and as for precission and repeatability a simple microswitch is "good enough" so

but a real winner would be the heatsink-necklace as it has zero offset and requires less force than piezos.

I can't visualize how would this work

can you please share your config? this can help me too
