Many false positive errors #52

I've installed the v2 sensor at my creality K1 (only the motion sensor As there is only one pin available) and I'm getting often false positive errors. My detection length is 4.5mm and I'm printing PLA. Any ideas? Will try to increase the detection length after the current print, but too long could cause other issues when there is a real error 🫤

That device is a crap. I cut out motion detection sensor feature from firmware and use it as normal (yet overly expensive) switch.

During my attempts encoder sensor worked at complete random. Stating "filament present" when there was no filament at all, or throwing random runouts few seconds after print starting. I was unusable, no matter what detection length I set in firmware. Many other people also had that issue, there need to be some flaw in its design.
