Progress Log

- Serious consideration needs to be taken for moving forward. I now know that this procedure works; the prototype works admirably given how it was constructed. The system needs a redesign, and I want to make sure I select the correct path going forward. Currently, the pop-bar lays in a channel milled into the bed, this is a holdover from when I imagined this procedure against the default printrbot build plate. The channel warps the build plate, so this design must go. I now think that the build plate could be constructed from three discrete parts, with the pop-bar laying between two separate plates of alum. There may also still be a better way to detach parts from the build plate, I'm not sure.

- After several prints with the printrbot outside of its enclosure, it is apparent that some climate control is needed. Each print has warped and curled fairly heavily. A custom box must be constructed, or a large cardboard box must be found.
- The pop bar has worked well for the past dozen or so prints and failed prints. Collection of ways to remotely screw up the printer and then recover is growing quickly.
- I learned to NOT try melting plastic off of the print nozzle, because then the plastic inside will char and clog everything. Will test whether a lower temperature is appropriate.
- The print bed is warped, contributing to the jammed nozzle. I cannot determine if this happened while milling, or due to torque from mounting it on the printer. I rigged up a vice and flexed the plate back to near-level, but it appears to be bending again once remounted. Future print beds must be designed to minimize this.

- The second pop-bar, which I am considering a true prototype, has been created and linked to an active servo.

- The testbed for train_rec was a success. Rather than use the length of the pop-bar as a lever to pry the piece off of the bed, I think its better to twist the bar along the length to push the 3d printed part up.

- Milling the "production/testing" bed is next on the list.

ffmpeg + ffserver
I also tried ffmpeg+ffserver. Didn't go over well, I'm not patient enough to learn how to set it up correctly.
