not getting data from filament sensor

M591 D3 P7 C"duex.e5stop" S0 R25:1000 L12 E20 A0

when running a M591 D3. i am not getting any data collection. even after a very long time.

I purposefully increased L so it won't pause when i had S=1. I now changed it to S=0 so it doesn't pause during a print when trying to figure this out. I think I have my extruder drives correct. It is the fourth extruder in line. The wiring looks good too. I can see the encoder LED turn off and one and it is in-sync with the LED on "duex.E5stop". I can't figure out why it is not collecting data.

BElow is what i am getting:
m591 d3
Pulse-type filament monitor on pin duex.e5stop, enabled, sensitivity 12.000mm/pulse, allowed movement 0% to 1000%, check every 20.0mm, no data received

no data received

Which firmware version are you using? Do you have a spare endstop input on the Duet that you can use instead of the one on the DueX?

tekstyle

@dc42 firmware is 3.3.

i can try to map it over to one on the duet2 instead but i will have to use duex endstop anyways as there are 4 tools.

@dc42

so plugging into E1stop gives the below

M591 D3
Pulse-type filament monitor on pin e1stop, enabled, sensitivity 3.000mm/pulse, allowed movement 0% to 1000%, check every 20.0mm, no calibration data

@tekstyle

anyone know why filament sensing works on the duet2 but not on the duex5 endstop input?

@tekstyle The endstop inputs on a Duex do not connect directly to the Duet 2, instead they connect to an IO expander on the Duet and as such are not supported for filament monitors:

https://duet3d.dozuki.com/Wiki/Duet3dFilamentMonitor_RotatingMagnetVersion#Section_Duet_Num_2

Note: The Filament monitor must be connected to an endstop on the Duet 2 Wifi, Duet 2 Ethernet or Duet 2 Maestro. It does not work connected to an endstop on a Duex expansion board.

If you need to connect 4 then use 4 endstops on the Duet 2 mainboard and connect axis endstops to the Duex5.

@t3p3tony

thanks for clearing that up. ill do what u suggested and report back. can the X Y Z endstops be used for filament monitor?

Yes, and with RepRapFirmware 3 you can use other inputs for the XYZ endstop switches.
