	*Manufacturing: Success. Templates work well for precision. Minilathe-made couplings suffice. Bandsaw cuts are fast and accurate enough. Timing: P2 Build 2 weeks		*Manufacturing: Success. Templates work well for precision. Minilathe-made couplings suffice. Bandsaw cuts are fast and accurate enough. Timing: P2 Build 2 weeks once materials are sourced. ETA for return to FeF: March 20. Parts arrive at FeF by March 20.

	*Software: Success. GRBL and gctrl (a GUI code that runs within Processing, allows you to stream gcode files to Arduino and do manual jogs) compatibility established. Integration with hardware established. Next steps: establish and document circuit-to-gcode toolchain. Proposed solution path: use a popular OS circuit editor such as gEDA or Kicad to generate Gerber files. Gerber files are then coverted to production machine specific language, via any suitable, open source PCB gerber file to gcode converter - which will be adopted to the OSE CNC Circuit Mill.		*Software: Success.
