This Week:
This week, I spent a lot of time printing the (hopefully) last components. This includes both the cable snakes (for routing cables to the moving gantry) and the final attachment points for the top and bottom boards. The base model for the cable snakes was taken from thingiverse (https://www.thingiverse.com/thing:3715002) and modified by me to fit our needs. The attachment components were fully modeled by myself.
Cable Snakes from Thinkgiverse (second print of 103, 130 surviving total)
Assortment of attachment points for top and bottom panels of wood. Cad model render not pictured.
Aside from printing the cable management parts, I also did cable management. The stage is now able to finish its homing sequence without ripping out any cables. While I haven’t conducted a stress test in fear of cables internally shearing, it survived around 5 to 10 homing sequences, so I think it’s sturdy enough.

Schedule:
I am on schedule.
Next Week:
- Cut out the top and bottom wood pieces
- Attach the bottom and top plates to the assembly
- Route the charger’s cable to the stage
- some cable management and maybe a piece of wood to keep all the arduino and wires tucked in the safe back area
- Assist Cal with firmware interfacing
- Measurement of specs will likely have to occur during finals week
