Is there an existing issue for this feature request?

I have searched the existing issues

With the snapmaker U1 incoming, along with it's 4 tool heads, a nice feature would be to allow at least one tool to be plugged with an AMS like system and enable the single extruder multi material option on it, in addition to the multi tool.

That means that we could use more than 4 colors on the U1, also that would allow to use filament which properties change with temperature like varioshore tpu, lw-XXX or durometer tpu Air.

i think that to make it easier to develop it, limiting this option to the last available tool would be a good first step to enable it.
this would allow to be used the same way if you have 1 or 4, 5, 12 tool heads.

of course this will take the swapping purge chart into account when using this specific tool only, not the others (and not if the swap is between this tool and other tools)

thanks for reading

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

On a multi tool configuration, i can also check the "single extruder multi material"
this would display the add and remove spool icons.

these added spools would be linked to the last toolhead (in that case if we have 4 tools and an AMS, T0 to T2 would be separate tool, while T3 to T6 would be linked to the 4th physical tool and matching added spool on the AMS)

The purge color chart would be used when swapping from [T3-T6] to [T3-T6]
but not when swapping from other combinaison ( from [T0-T2] to [T3-T6], from [T3-T6] to [T0-T2] and from [T0-T2] to [T0-T2] ).

Describe alternatives you've considered
