RRF3.4 RC2 Filament error on extruder 0: sensorError

charliedrums

It happened a third time at arround 90% complete. same error

3/11/2022, 2:09:48 AM 	Error: Filament error on extruder 0: sensorError

Phaedrux

How is your cabling run?

Our best guess is that interference is corrupting the signal from the MFM and that RRF 3.3 wasn't very good at reporting that type of error.

Are you able to swap back to 3.3 to see if it becomes less sensitive again?

charliedrums

@phaedrux Yes I can.

I'm Going to run a 17 hour print with the cable routed by itself away from any other cable. (it is connected to the toolboard 1LC. See if I get the error and then I'll downgrade to 3.3. Do I also have to downgrade the toolbard to 3.3?

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.

charliedrums

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