Motorized flipping mirror mount

thingiverse

This is a motorized kinematic mirror mount, designed to move mirrors in and out of the optical path with precision. The mount is specifically engineered for use with Nema17 stepper motors (size 42mm x 42mm x 40mm), which provide the necessary torque and control for smooth movement. A shaft adapter is also included, allowing users to easily attach the mirror mount to Thorlabs' kinematic mirror mounts, such as the KM100. Endstops are strategically placed at both ends of the travel range, ensuring that the mirror stops moving when it reaches its limits. These endstops are made from standard 6x6mm Arduino pushbuttons, which are mounted on top of posts that are printed separately and connected to the main frame using M3 screws. The shaft adapter and endstop posts feature holes for M3 screws, but require gentle threading with an M3 tap to ensure a secure fit. Users can then bolt the entire assembly to Thorlabs' BA2/M plate for post mounting, providing a stable and rigid foundation. Motor control and tracking of endstop status are handled by a RAMPS 1.4 shield, Arduino Mega board, and a modified branch of Marlin software. This setup allows users to precisely control the movement of the mirror mount and monitor its status in real-time.
