IR Height Sensor
-
I finally got around to building my third printer. All 3 are exactly identical printers. I am noticing a weird issue with the 3rd IR height sensor. It boots into digital mode just fine, but it seems to trigger at 2 different heights. The first height is well off the bed, second height is about normal. Never seen this before. Is this unit defective?

@br7408 ISTR that there is a chance for false triggers at high distances due to stray reflections. I dont remember what the workaround/mitigation was.

@oliof It has this issue with any surface.
-
@br7408 it may be a faulty probe, a similar case of this was handled under warranty (ref https://forum.duet3d.com/topic/30051/ir-probe-faulty-triggers-well-before-the-actual-trigger-point/22). One for @Phaedrux I guess.

HMMM. Strangely it seemed to fix itself somehow. I wonder if the EBB 42 woke up stupid or something.
-
@br7408 it didnt endeavor the threat of replacemebt I guess.
