Duet Laser Filament Monitor

  • I am trying to calibrate my duet laser filament the LED is pulsing but when I send M591 D0 shows this
    Duet3D laser filament monitor v1 on input 10, disabled, allow 35% to 180%, check every 5.0mm, no data received

    and when I Enable S1 too little movement reported .
    and print pauses.

    You need to do a print to calibrate the sensor (with the sensor disabled i.e. S0 in the M590 command) then M590 D0 will display the accumulated calibration data too. But the "no data received" message suggests a wiring or configuration error.

  • Thanks, I will do a print and check

  • the Issue is with the Data out from the laser filament sensor to CONN_LCD to pin 10)Stp 11(LCD_DB4) no Data receiving!
    when I connect the sensor out to E0 STOP works flawlessly.
    is my configuration C10 is correct ?

    If you connected it to STP11 then you need C11 in that command, not C10.

  • @dc42 Solved!

    it looks like I was using wrong Pin for data , it works now with CONN_LCD
    4) STOP 11 (ENC_A)
