Spindle Failure mode addressed. http://opencircuitinstitute.org/content/configure-circuit-mill-development-log-spindle-dropping-auto-probing-and-z-axis-failure-mode

Review of performance:

• Defending Master's thesis - this summer
• Spring for the CNC Circuit mill - put 4 around the rods - weight is about 1 kg, so force constants of 4 springs at 250 g per inch
• Issue resolved - slip of motor - just put a single rubber band on the circuit mill
• Start time sheet -
• Wood backing - appears to be not needed
• Spindle slip from holder - fixed with rubber bands.
• Larger motor driver fixed z motors slipping slightly down
• Software screenshot - http://opencircuitinstitute.org/content/oci-copper-carve
• Hardware - https://www.youtube.com/watch?v=lcineYCNqX0&feature=youtu.be
• Do 1/4" plate, otherwise would have to test a thinner plate
• Do a 3D printed enclosure for all electronics?
• Plan on a good manual - Scribus
• Revenue models - on-demand printing of Manual + information products
• http://opencircuitinstitute.org/content/schematic-design for printer friendly version
• Start using time sheet.
• Feb hours - 30 hours
• Current Meeting
