Testing filament sensor on RRF3

gnydick

I'm running the first stable release of RRF3, and I can't get the filament sensor to work as expected.

If I just unplug the sensor, the print pauses, but if I cut the filament and it runs out, nothing happens.

I'm running A DIY encoder wheel w/optical sensor.

The documentation for managing pins for RRF3 is a bit light. As far as I can tell, I don't need an M574 to setup the endstop since I'm just using its pin.

first stable release of RRF3

probably a good idea to move on from the first stable (3.0) to the latest (3.1.1), lots of issues fixed since then

What does the console returns when you send M591 D0 during a print

gnydick

M591 D0
Extruder 0 has no filament sensor

So I set it up again.
M591 D0 P7 C"duex.e2stop" S1 E50 L1.739 R50:150

Error: unsuitable pin

But other times it works it creates the sensor. I don't know what's going on.

@gnydick Pin names for Duet 2 Wifi are here: https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Pin_names_for_Duet_2_WiFi_Ethernet
Do you have a Duex connected? If not, and you're plugging the sensor into the expansion header, try using "exp.e2stop" instead.

I have the duex. Looks like since I only have E0 and E1, I can't use the E2 stop. When I switched it to "e0stop" it's working. Can the pins be reassigned so I can use the header on the duex?

@droftarts so far, it's triggering even if the wheel is turning. It says this

Pulse-type filament monitor on pin e0stop, enabled, sensitivity 1.739mm/pulse, allowed movement 50% to 150%, check every 5.0mm, no data received

fractalengineer

@gnydick good, now that it's plugged proper, please update the config to the following: M591 D0 P7 C"exp.e2stop" S0 E50 L1.12 R50:150 A1

S0 disables monitoring so that it won't interrupt the print
and A1 measures only during extruder moves.

Then could you run a print, run a couple M591 D0 during the print and share the returning messages here?

We're looking for the measured sensitivity for calibration

@fractalengineer thanks!
