How does Spoolman detect Filament change in Print via CFS/AMS

How does Spoolman detect Filament change in Print via CFS/AMS?
I use Spoolman since a few weeks, it runs on a raspberry pi as standalone.
How does it or can it detect manual or automatic filament change per CFS/AMS?
I won’t click at the right moment for change or edit the filaments manual after print.

Spoolman does not detect anything. To automate things your slicer needs to be set up so that each material has an corresponding Spoolman ID in it's data, and your printer needs to have SET_ACTIVE_SPOOL and CLEAR_ACTIVE_SPOOL macros defined.

This is how my GCodes are set up in Orca Slicer:

I set this for every Material I have, so when I start I print I don't have to select a spool manually. Same if I switch materials in the slicer the switch for Spoolman works without intervention.

My printer has corresponding macros set up here in Moonraker: https://moonraker.readthedocs.io/en/latest/configuration/#spoolman

Hope that helps
