Chase’s Notes

General Mitosis:

What to expect this semester:

• 2 in-person meetings:
  • Call these “Test meetings”: These meetings are meant to test new design hardware or software.
• 2 online/CAD meetings:
  • Call these “design sprints”
  • 2 hours long, these meetings are for quick iterations. Start each meeting with a 2-hour goal, that can be completed in time for testing at the next in-person meeting.

Mechanical

Essential:

• [ ] Minimize wobble of XY riders
• [ ] Refine and perfect bearings
• [ ] Perfect bed-adjustment screws— No creep, but easy to turn.
  • [ ] Integrate bearing
• [ ] 3D printed BL Touch/bed-leveling Sensor
• [ ] Perfect Ball-bearing for leadscrews

Extensions, High Priority:

• [ ] Adjustable Angle Nozzle
• [ ] Epoxy Toolhead (could make the build tray)
• [ ] Tool-changer mechanism
• [ ] Injection Molding nozzle (For Mitostruder)
• [ ] Mitostruder
  • [ ]

Extensions, Lower Priority:

• [ ] CNC/Sander tool head.
• [ ] Pipe/tube extruder.

Extensions, No Priority:

• [ ] Strain-gauge for auto-calibrating XYZ distance moved per step. (note: resistance changes over time)
• [ ] Robot Arm-Printer interface for assembly

Personal Goals:

• Rhea:
  • Get the toolhead by mid-February, print it, and see how it works.
• Hiking
• Chase:
  • Z-axis by the end of January
  • See who else is returning
