Hi!
I'm thinking to buy a Diamond hotend and use it as a switching color hotend, not mixing (I read that passive mixing is not ideal, because of the toothpaste effect).
In theory, switching only needs 1 motor, as only one filament is used at a time. But in the case of the Diamond, all filaments have to be engaged, to avoid back extruding in unused heads.
My first question is: do unused filaments need to be maintained by their respective motors? My first idea was to use only one motor, and a servo to move a gear to choose which filament to drive... But this means that unused filament won't be maintained.
My second question is about Bowden tubes: what is the maximum length I can use? What happens if using too long tubes? I would like to put the extruder on the (coreXY) frame, not above with a swinging stuff.
Thanks for your help.

Use a piezo sensor for each head to determine Z offset.
