Maybe I’m overlooking something basic, but changing the hotend doesn’t help me at all if I want to change the filament.
Sorry, I don’t understand how that’s supposed to save even a single poop.
Just had a second look.
The six hotends are not ‘loaded’ with filament and also this would not work by putting them in the gantry from below.
The hotend switch may work flawlessly. But why should I change hotends if I just want to change the filament? (And that is the part where the poops come from.)
And for the change I would need to clean the old hotend and cut the current filament before storing it. (That is one poop.)
Then after the new hotend is loaded it would need to load the filament in the clean/empty hotend and to make sure it is completely filled you need to have some filament comming out of the nozel. (Second poop).
I’m sure I’m overlooking something basic.
