Laser filament monitor and pressure advance



  • Hi all
    I have recently set up a laser filament monitor (1.7) on my Maestro ( firmware 2.03 ) possitioned between the extruder and spool on my Bowden setup. ( Min 40 max 140 ).

    All is working well and seeing good measurement %s on consistent print moves usually between 80-100%. However on very small infill moves ( line distance ~1mm ) I was seeing constant pauses per layer and measurements of min 10% and max 37% when pressure advance was active ( set to 0.15 ). As soon as I disabled pressure advance the measurements jumped up to min 43% max 81%.

    I'm just wondering if its possible for the laser filament monitor measurements to be negatively impacted by pressure advance.

    Thanks Nigel
