(Asked by: username_0 on 2018-09-07)

I am using Prusa i3 MK2s with the first version of the multi-material add-on.

As far as I understand, the slicer defined the used feeding motor using the `T0`-`T3` code which defined one feeder at the time.

Is there a way to have two feeder motors working at the same time?
