RRF3.4 RC2 Filament error on extruder 0: sensorError

Phaedrux

@charliedrums said in RRF3.4 RC2 Filament error on extruder 0: sensorError:

Do I also have to downgrade the toolbard to 3.3?

Probably should yes.

charliedrums

Just got the same error with the sensor cables not touching or near any other cable.

charliedrums

What gauge wire should I be using for the filament sensor?

Phaedrux

I don't think the gauge is especially critical as it's just low voltage signaling. Noise rejection would be more important. You could try braiding the cable, but if it's already running away from other cables that shouldn't be an issue either, but even a longer run of wire can act as an antenna I suppose.

charliedrums

Finished downgrading the 6hc and 1lc to 3.3. Going to start a 17 hour print and see how it goes will report back with findings

charliedrums

Just got the same error but this time it is not on the console event. It was a pop out on the DWC where it says printing paused because extruder 0 reported "sensor error" once I close it there is nothing on the console.

Prior to resuming the print:

Once the print finishes I plan on remaking the small harness for the filament sensor to see if that helps in any way.

Phaedrux

Can you show a photo of how you have it mounted/installed?

When and where did you purchase the sensor?

charliedrums

@phaedrux

Re wired the sensor and made sure I the connections were solid but just got the error an 74% complete. I bought it from filastruder on January 15th 2022. Here is how it is currently installed.

BoA

@charliedrums Can You check, if Object Model has correct data for this filament sensor? In my case they do not correspond to what is configured by M591

charliedrums

@boa Object model? I kinda lost you there.

BoA

@charliedrums In DWC:

M591 D0 P3 C"io5.in" S1 L25.4 R50:150 E12.7 A0, so sampleDistance, allowed range and mmPerRev have incorrect value (I think)

charliedrums

@boa Got you. Will do. At work right now but once I get home I'll check it out.

dc42

@boa I confirm this is a bug: changes to the filament monitor configuration values are not reflected in the OM browser in DWC. They are reported correctly by M409.

charliedrums

@boa I don't seem to have that on my DWC

Maybe because I'm running on a SBC (raspberryPi)

charliedrums

On my last print I had the error occur once and the print took 17h 41m 30s

The object model browser is a plugin you'd need to load.

Can you check this thread for an updated housing for the sensor?

This person had good results from the change.

https://forum.duet3d.com/topic/27661/mfm-0-toolittlemovement/9

charliedrums

@phaedrux Will print the housing and test to see if that helps.

charliedrums

@phaedrux Reprinted the housing and assembled everything. My agc was a little low so I had to take it apart an shim it with a piece of paper. Now I have an agc within the range (59)

Duet3D rotating magnet filament monitor v3 on pin 121.io1.in, enabled, sensitivity 24.84mm/rev, allow 35% to 130%, check printing moves every 15.0mm, version 3, mag 131 agc 59, measured sensitivity 25.12mm/rev, min 98% max 101% over 781.5mm

I'm wating on some filament to start a couple of 15 to 17 hour prints to see if I keep getting the issue.

O and I updated to the RRF3.4 stable release.

Just if anyone was wondering, I make hand drums to play Plena (music from Puerto Rico) and I built a 24inx24inx26in printer to be able to print the drums in one go using the duet. That's why I have so many 15 to 20 hour prints to do.

Phaedrux

@charliedrums said in RRF3.4 RC2 Filament error on extruder 0: sensorError:

agc 59

Still seems a bit low.

charliedrums

@phaedrux I showld shim it again? what would be a normal value?
