The original sensor is known to deliver a bit random results.
ABL is not needed,
so why not just use a microswitch instead, see the pictures for results, with this microswitch,
clearly 10 times as accurate over any other sensor i tried.
my plate is not bend, so it is perfectly more than enough just to trim level on the 4 corner knobs of the bed.
