Abort command in load.g or unload.g filament macros changes filament, as it was correctly loaded/unloaded

[michele-bertoni]

If an abort command is called when loading or unloading a filament (both with M701 or M702 and with the Duet Web Control), Duet will then change the filament name of the associated tool, as the filament was correctly loaded or unloaded. A very strange behavior happens, instead, when an error (such as G0/G1: insufficient axes homed) is thrown: in this case the filament name is not changed. The problem happens both if the abort command is inside load.g/unload.g file and if it is inside a nested macro called by load.g/unload.g.

forget abort, you can't even change filament without it resetting

You mean the error present in latest beta release? It has already been fixed for the next beta release

[zombiRon]

Yes, so how are you testing this without it resetting?

I'm using latest working release and, since I haven't found anyone reporting this bug, I assumed that it wasn't fixed yet

[zombiRon]

you're running 3.1.1?

[michele-bertoni]

Yes, 3.1.1, last stable release

I found out that if the tool is deselected (with T-1) at the time the load/unload macro ends, the filament won't change its state. So, if you do T-1 before calling abort, it works fine.

This issue is present in release 3.4.5.
If you run abort "Cancel load" inside /filaments/<filament>/load.g or inside a submacro of load.g the Filament will change state.

This also happens if your macro contains M291 command with S3. If the user presses "Cancel" the filament will change to the new state.

Closed as M99 is the correct approach - see the forum thread.

abort commands are not supported at this point in system macros.
