@themelle thanks for confirming.

Thanks for reporting this, it will be fixed in the next DWC version.

@Phaedrux yes for "KISS" it is rather far from that!

The replacement filament monitor arrived today - thanks for the really fast and painless swap!

Just installed, gave it a quick go ...

no more "Sensor not working" messages M591 D0 reports quite usable data Duet3D rotating magnet filament monitor v2 on input 3, disabled, sensitivity 25.33mm/rev, allow 85% to 115%, check every 3.0mm, current pos 14.8, measured sensitivity 25.21mm/rev, min 90% max 110% over 1252.5mm M122reports no frame errors anymore Extruder 0: pos 14.77, ok, measured sens 25.21mm/rev min 90% max 110% over 1252.5mm, errs: frame 0 parity 0 ovrun 0 pol 1 ovdue 0

Will do some more tests in the coming days, but those are by far the best results I was ever able to get!

Thanks to both the teams of Filastruder and Duet3D for your great support!
Much appreciated!

So it is essentially a matter of personal preference or part availability, and there are no real differences between fans for different voltages.
That is what I wanted to read 😉

Thank you, David.

Thanks for the quick response!

I understand that there are plenty of other things to be done first - I just wanted to be sure you noticed the voltage levels measurement you requested.

Thanks again!

I don't know why it only occurs on a layer change. The DRV8825 datasheet says it requires 1.9us step pulse with, 1.9us setup pulse interval, and setup and hold times both 650ns. So you should use at least T1.9:1.9:0.65:0.65 in the M569 command. What's surprising is that it works at all if you don't extend the step pulse width.

In practice, the values you specify in the T parameter get rounded up to the nearest multiple of the step pulse clock interval, which on the Arduino/RADDS is 1.52us.
