2014-07-12 (Sa) Upcycled 3D Printer

The first attempt to eject glue was entirely unsuccessful since no hole had ever been drilled in the pie tin for the glue to come out. The glue nozzle became clogged but functioned properly otherwise. A thermal printing label was applied to the bottom of the pie tin with the nozzle plugged with the plan to make the nozzle location apparent by the part of the label that would change color due to the heat. No color change was recognized.

There should be a hole in the center of the pie tin. There isn't

The label should be black where it gets hot. It isn't

The program was updated so the printer advances one iteration with each button press instead of multiple button presses necessary for each layer of the print. The factor for relating the inter in the program to time was arbitrarily set at 8 with a debugging potentiometer. The time to fill the air tub was moved to a variable and set to 15 seconds for the purpose of testing. The lowering time of the platen was set to the value determined by time testing.

To do:
  • Flip platen or extruded u-nuts
  • Drill hole for hot glue nozzle
  • Extend wires of waterServo
  • Make and install mount for waterServo
  • Correct + Install air tube
  • Test + Debug
  • Revise documentation
