Overview

cOssel is an iteration of Johann's Kossel. Design intents are equip a dual head end effector and to move the linear rails to an open design. It will also convert from 15x15 to 20x20. All other tweaks are minor. This design otherwise entirely copies Johann's delta-bot intent.

Non-contact Autoleveling

cOssel attempts to enable a low-power, non-contact autoleveling sensor as an alternative to using a retractable mechanical switch as used in other Rostock/Kossel deltas.

Assembly

Pre-install nuts for easier extrusion install

The assembly process should take a short weekend to complete. Make sure that you have a standard tool set, including ball-end metric allen keys.

The following images show the terminal block on the board. I ended up removing the terminal blocks from the boards to reduce interference from the carriage assembly as it approached the Z_MAX home position.

Rod Ends

It is assumed that your push rods have already been cut to size by yourself or a vendor. If not, cut your rods to length.

  1. Place the rod end ball standing vertically on a stable surface.
  2. Place the rod end socket loosely over the ball end ball.
  3. Space a pair of needle nose pliers around the perimeter of the socket.
  4. Press firmly down and click the socket over the ball.
  5. Prepare the epoxy solution.
  6. Apply dab of mixed epoxy onto threaded 4mm dia, 20mm long set screw
  7. Thread set screw into rod end as deep as it will go
  8. Apply another dab of epoxy onto the set screws, this time, more generous
  9. Gently place the set screws into the carbon fiber tube.
  10. Firmly press both opposing rod ends together along the tube axis.
  11. Set rod to try. Ensure that rod ends are parallel with each other.
