Jake's Notes
-
doc
-
bom
-
hardware callout drawing (probably more useful than video)
-
nice to include a note on what those flexures are up to ... and some other design decisions
-
kinematic mounts are three button head cap screws on 20mm grid w/ reciprocal / wherever-u-like mount ins
-
all axis have scroll-along top plate w/ connection to motor plate, final scroll kinematic triangle
-
all axis have scroll-along bottom beam plate w/ 20mm grid w/ last scroll kinematic triangles
