Filament monitors

zendesigner

Hi,
As i'm going over all my printers to get them perfect, i noticed now in my Tronxy5 3 extruders that my filament monitors have not been tested yet.

When i do a M591 D0 i get this:

Duet3D laser filament monitor v1 on pin xstop, disabled, allow 10% to 120%, check printing moves every 3.0mm, calibration factor 1.000, version 1, measured min 0% avg 0% max 0% over 911.0mm

It seems not to measure anything. they have their ligths on and flashing so might be something else.
this is my config

;filament monitors
M591 D0 P5 C"xstop" R10:120 E3.0 S0 ; Duet3D laser sensor for extruder drive 0, connected to endstop input 0 (E0), tolerance 10 to 120%, 3mm comparison length, disabled
M591 D1 P5 C"ystop" R10:120 E3.0 S0 ; Duet3D laser sensor for extruder drive 1, connected to endstop input 1 (E1), tolerance 10 to 120%, 3mm comparison length, disabled
M591 D2 P5 C"zstop" R10:120 E3.0 S0

thanks zen

@zendesigner perhaps the laser filament monitor can't see your filament? There are some filaments that it doesn't work well with. Does the green LED on the filament monitor flash continuously when filament is moving through it?

hi thanks for the help. they flash quick blue when filament goes through, but one didn't do it consistently.
I removed it and there was some scraping dust blocking inside the sensor. so that was the culprit.

it's starting to measure now

Duet3D laser filament monitor v1 on pin xstop, disabled, allow 10% to 120%, check printing moves every 3.0mm, calibration factor 1.000, version 1, measured min -1% avg 0% max 0% over 92.9mm

cheers

mmm, now it stays -1% to max 1% ??

Duet3D laser filament monitor v1 on pin xstop, disabled, allow 10% to 120%, check printing moves every 3.0mm, calibration factor 1.000, version 1, measured min -1% avg 0% max 1% over 14966.6mm
