filament-error#.g usage help? Avoid pausing on sensorerror?

OwenD

*Upgrade notes:

The handling of filament errors have changed. When a filament error occurs, an event is created. To handle the event, RRF runs macro file filament-error.g without appending the extruder number to the file name and without pausing the print first. The extruder number is passed as param.D along with some other parameters. If filament-error.g is not found then the print is paused (running pause.g) and the error is reported.*

I ended up with this being my config for filament-error.g. Since a rotating magnet filament sensor, "tooLittleMovement" doesnt seem to be a "status" of the sensor, so I just made a config to filter out transient issues (sensorError and noDataRecieved) and only stop the printer if those 2 status conditions are not present.

if {param.D ^ ""} = "0"
	if sensors.filamentMonitors[0].status = "sensorError"
		echo "SensorError-0 Continuing to Print"
		
		M99
	if sensors.filamentMonitors[0].status = "noDataReceived"
		echo "noDataReceived-0 Continuing to Print"
		
		M99
	echo "Too Little Movement-0-Paused"
	M291 p"Filament Sensor 0 - Too Little Movement" S1
	M25 ;pause the print
	
if {param.D ^ ""} = "1"
	if sensors.filamentMonitors[1].status = "sensorError"
		echo "SensorError-1 Continuing to Print"
		M99
	if sensors.filamentMonitors[1].status = "noDataReceived"
		echo "noDataReceived-1 Continuing to Print"
		M99
	echo "Too Little Movement?-Paused"
	M291 p"Filament Sensor 1 - Too Little Movement" S1
	M25 ;pause the print

M99

Glad you got it working.
There's no real need to duplicate the code for each sensor as you can use the D parameter to show which is in error state.

if sensors.filamentMonitors[param.D].status = "sensorError"
	echo "SensorError- sensor : " ^ param.D ^ " Continuing to Print"
	M99

if sensors.filamentMonitors[0].status = "noDataReceived"
	echo "noDataReceived -sensor " ^ param.D ^ "Continuing to Print"
	M99

; catch all for any other error type
echo "Filament error on sensor " ^ param.D ^ " - Paused"
echo param.S ; echo the entire error for clarity
M291 P{"Filament Sensor"  " ^ param.D ^ " - Paused"} S1
M25 ; pause the print

@owend ahh yeah! thanks I'll clean that up

@clegg78
You might also want to do a check at the start to see if there is an active tool so that if you remove the filament at any time from a second (inactive) tool it doesn't pause.
Likewise you could check to see if the sensor that is raising the error belongs to the active tool, but I can't see a way to see which tool(s) each sensor is associated with in the object model.

I too get a sensor error every 20h or so and I did just put this into filament-error.g:

if sensors.filamentMonitors[0]status != "sensorError"
        M25

I tried to monitor the sensor status, but I suppose I made an error somewhere.

I always get "OK" status when reading the sensor status after an error.

var StatusTest = sensors.filamentMonitors[0].status

if {var.StatusTest} = "sensorError"
	M291 P{var.StatusTest} S1
	;M291 P"Filament Sensor - Sensor Error" S1
	M24
	M99
if {var.StatusTest} = "noDataReceived"
	M291 P{var.StatusTest} S1
	;M291 P"Filament Sensor - No data received" S1
	M24
	M99
if {var.StatusTest} = "tooMuchMovement"
	M291 P{var.StatusTest} S1
	;M291 P"Filament Sensor - tooLittleMovement" S1
	M24
	M99
if {var.StatusTest} = "tooLittleMovement"
	M291 P{var.StatusTest} S1
	;M291 P"Filament Sensor - tooLittleMovement" S1
	M25
else
	M291 P{var.StatusTest} S1

This look like I don't read the right value or it's refreshed since the event was raised and called the filament-error.g

Any help will be appreciated

I also needed to use this workaround because meanwhile all values, from agc to calibration and what ever is needed to get this magnetic filament monitor to work, are fine i still get this filament error which i cant debug because i dont get any information what the error is actually about...

this whole filament monitor is not a finished product as duet is selling it - its at best experimental!!! The time i spend to get it working was crazy and i think as consumer you should know this befor buy!!!

also this what should this min -710% and max 468% tell me... also didnt stop the print and didnt trigger any alarm ... Screenshot 2025-01-04 192407.jpg

@juanito16k Have you started a thread for your issue? It would be easier to troubleshoot if we discuss it there instead of in a 3 year old thread.
