Hi all,
I have a filament sensor configured for my Prusa Bear MK3s (Duet 3 Mini 5+; RRF 3.4.0; DWC 3.4.0):
M591 D0 P2 C"io3.in" S1 ; configure filament sensor for extruder drive 0 on pin io3.in and turn it onHere is my config.g:

So when I power up the printer and no filament is loaded, I get the following message:
Error: Filament error on extruder 0: noFilamentThe message alone would not be a big problem (still feels misplaced though) but I have some macros where I am unloading filament first (like for PID tuning). Once I unloaded the filament, I get the above error and the macro is interrupted and won't continue without manually triggering it again.
Am I doing something wrong? My understanding is that the error should only be reported/or interrupt when the printer is actually printing from SD card.

Here is the PID tuning macro I am currently using for the nozzle as example:

@flobler Activate the filament sensor only when printing.
One way to do it:
Configure it using S0, I have it in the config.g. In your start .g use M591 S1, and in cancel.g and stop.g use M591 S0. -
@stephen6309 Thank you, I will try this!
But in the end, should it not only report errors while printing anyway? I thought
S1would configure it for that according to: https://docs.duet3d.com/User_manual/Reference/Gcodes#m591-configure-filament-sensing -
@flobler When running a gcode file on the sd, it's processing, which is the same as printing.
-
@stephen6309 that makes sense, I assumed there would be a different between the status "printing" and other things the printer is busy with.
Thank you for your help, I assume what you suggested will solve my problem but I'll still update here once Itested this

This fixed my issue, thank you for your help @Stephen6309!
