Pause avoids M600 to execute

Tinchus

Hi. I have setup an end of filament sensor in the way of an encoder, it works really well. But today I did real test: it detexcts perfectly when no filament is there, pause the print.... acording to my filament-error file it should laucngh a message after the OK should run an M600 command and so execute filament-change.g file.

All goes well exept that everything stops at the message, afeter Y press ok, M600 is not execute nor the echo line I intruded later as a debugging

My files:

pause.g

		echo >> "errors.log" "filament error from filament monitor code: "^{param.P}^" "^state.time^""
	if (global.filamenterror = 4) | (global.filamenterror = 5)
		M291 S2 R"Filament error" P"No filament or possible jam on hotend. Print has been paused, manual intervention required. Press ok when ready"
		echo >> "errors.log" "filament error from filament monitor code: "^{param.P}^" "^state.time^""
		M600
if param.D = 1
	if (global.filamenterror = 4) | (global.filamenterror = 5)
		M291 S2 R"Filament error T1" P"No filament or possible jam on hotend in T1. Print has been paused, manual intervention required. Press ok when ready"
		echo >> "errors.log" "filament error from filament monitor code: "^{param.P}^" "^state.time^""
		M600
echo >> "error.log" "filament error triggered "^state.time^""

Also, if being paused and in console I execute M600, nothing is done, like the command is being ignored.

Thanks in advanced for the help you can provide me

Likely because M600 is itself a pause, though it's intended to be used within a print file.

https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m600-filament-change-pause

Instead of pausing on filament out, just call M600 directly to initiate the filament change pause and handle it within filament-change.g

@Phaedrux is like you said. "Problem" solved. Thank you very much.
