@tdybare69 said in run out sensor:

When you run M591 D0 to report the filament sensor status, does it report the correct present/not-present status?

tdybare69

@dc42 i don't know what you mean about report. i put it in the firmware ,then run the extruder and pull the filament out by hand

@tdybare69 send M591 D0 in the console and look at the response, then try again with the filament present and see if there is a difference.

Simple filament sensor on endstop 3, disabled, output high when no filament, filament present: yes. with the filament out.
Simple filament sensor on endstop 3, disabled, output high when no filament, filament present: no. with the filament in.

So the logic is reversed. change the M591 command to be M591 D0 P1 C3 S1 as show here:

https://duet3d.dozuki.com/Wiki/Gcode#Section_M591_Configure_filament_sensing

Pnn Type of sensor: 0=none, 1=simple sensor (high signal when filament present), 2=simple sensor (low signal when filament present), 3=Duet3D rotating magnet sensor, 4=Duet3D rotating magnet sensor with microswitch, 5 = Duet3D laser sensor, 6 = Duet3D laser sensor with microswitch, 7 = pulse-generating sensor

Thanks, changed it to that got this reading, but does not stop when i pull the filament out while its extruding.
Simple filament sensor on endstop 3, enabled, output low when no filament, filament present: yes. while the filament is in.

@tdybare69 THIS IS WHT MY CODE LOOKS LIKE.
M591 D0 P1 C3 S1 ; sensor drive 0 is connected to EO endstop input, enabled, trigger M83

@tdybare69
sorry about the caps

I think the way your are testing it is flawed; from M591

Note that filament monitoring in RRF is only active when printing from SD card.

So you probably need to create a short test gcode file with a number of extrude commands in it, run that, and pull the filament out.

your right. i ran a gcode print on small item cut the filament. it worked. thank you
