Note[edit | edit source]

The microscope holder requires the large tool effector. The stl files available are not intended to fit all microscopes. The SCAD script should be modified to produce a holder that fits our scope.

Assembly[edit | edit source]

  1. Clean up the print and scrape out the bearing pockets with the small screwdriver.
  2. Remove all grease and corrosion inhibitor from the ball bearings. Use acetone if necessary.
  3. File:Athena microscope bearings.JPG
    Put bearings on magnets.
    Put the ball bearings on the three inner magnets on the top of the large tool effector.
  4. Mix a small amount of epoxy and smear some around the interiors of the bearing pockets. Align the fiduciary marks on the sprung tool mount and small tool effector and squeeze the sprung tool mount onto the ball bearings. Set aside to let epoxy cure. NOTE: If too much epoxy is applied to the bearing pockets, it can run down and epoxy the tool mount permanently to the tool effector.
  5. Ideally, the microscope is a friction fit in the holder, as shown below. If not, nut and screw pockets are part of the model, allowing one to use screws to hold the microscope in place (nuts are optional).

Athena Upgrades
The mobile tool effector permits easy change-out of tools on the end effector. The following require the mobile tool effector.
Cylindrical tool mount holds small cylindrical tools and is the simplest of the tool holders, having limited uses.
Sprung tool mount holds cylindrical tools in a sprung mount for pen plotting and vinyl cutting, for example.
Microscope holder holds USB microscopes, turning Athena into a quite good 3-axis microscope stage.
The fixed tool mount permits mounting and swapping of heavy, fixed tools that then work the moving workpiece. The following require the fixed tool mount.
Micro mill spindle mount permits attaching a micro mill spindle for small milling projects like PCB prototyping, milling small wood and plastic parts.
Syringe pump mount permits attachment of a 3-D printed syringe pump for printing and plotting viscous fluids.
