My biggest hope is the CFS has actually made some improvement on the amount of waste the filament changes produce in other brands. The amount of waste currently make the other brands expensive to operate in color when more filament is going in the bin than on the product. I do notice they have just made a change to extract the filament as much as possible before cutting it.

Just cutting the filament and pushing the filament piece that’s below out and not retracting it has the advantage that it makes clogs less likely, pulling molten filament back in the cold end always is a bit risky, it can work though if it gets enough time to cool.

I hope Creality is doing something similar to the new AMS partial retraction before cutting that saves 25% of waste.
