I have just seen this today. Are you going to base your "multiple filament upgrade" on this (see below) ?

      Hey Maugé,

      it is a very nice and simple way to work with multiple filament, but for me it doesn't look like solving all problems around dual heads...

      It might be nice when it's only about changing the colour, but you will not get sharp colour changes - when you manually retract one and insert another colour filament, you always get some of the before colour out of the nozzle and then a fluctuating colour change,
      and the same will happen with the filament junction.

      It will not work for using different filament materials like ABS and PVA, as you would have to wait for temperature change of the nozzle every time, and even worse you will get cloggings because the leftover ABS in the nozzle will freeze when the temperature goes down to the PVA temperature.

      So i am hopefully looking forward to a dual nozzle option from philippe.

      Thanks for showing though,

      Bye,
      Knut
