Is there any source code for beacon surface to interact with Klipper?
I’m planning to develop something like that but use a physical digital vernier caliper instead of eddy current because the surface i’m printing is not metal.
I would suggest taking a peek at klipper/extras/probe_eddy_current.py, ldc1612.py, probe.py, and bed_mesh.py. I tried using a digital dial indicator with a with a roller tip but the indicator sometimes would read off by 0.02mm. I essentially implemented the rapid scan and would read the relative height every mm after zeroing once on the build surface (reading a value change set my z probe offset + height delta to nozzle). I was using this for a 24" garolite build plate but I ended up abandoning this for another method that was exponentially faster.
