Alternative idea to the prismatic(slider).
To alternate between multiple hot ends, mount the hot ends on a revolving plate, and splayed as you have noted.
The plate is at an angle (cam), and revolves like the lens on a microscope with a small servo, or NEMA 8 stepper motor.
NEMA 8 Frame Size(20 x 20 mm)
1.8° Step Angle
Torque - Up to 4.25 oz-in
That idea crossed my mind exactly! haha ;)
I figured... why add weight at the worst place for inertia though? keep thinking, thinking, that's when I came up with this idea - which effectively does the exact same thing and add's no weight to the effector. The reason I decided to post it now is that my mind is overrun with ideas on how to "activate" the tilting revolute pivot on the prismatic slider. As-is it only needs to shift between -5 deg and +5deg. I really like the idea of using a pneumatic cylinder from my background skills, but I realize not everyone wants to add an air system to a pretty much purely electrically actuated machine lol. Discussing mechanics and reading about them on these forums is exciting to me so I'm anxious to see what creative ideas get manifested.
