This is an evolution of "Modulare Flexure Translation Stage" with different driver options and magnetic length measurement inspired from Youtube channel "Diffraction Limited" https://www.youtube.com/watch?v=MgQbPdiuUTw
With a voice coil, an Arduino, a Motor shield, 7 cylinder magnets and an AS5600 magnetic angle encoder one can build a translation servo with a nominal resolution of roguhly 2 microns. The flexure could be used for (cheap) manual operation without voice coil but with M3 screws for actuation. Due to the magnetic measurement the translation of the moving shuttle can be measured and no micrometer screw with scale is needed. Theoretical resolution of the magnetic scale: ~ 2um
A variety of actuation option is available:
1. Micrometer screw
2. M3 screw
3. Voice coil
Description of parts:
Base Flexure:
1 x Modflex_Base2.stl Base with recess for Grove-AS5600 Angle encoder
1 x Modflex_Shuttle.stl Moving shuttle with bay for array of cylind
