Overview

A medium sized CNC Machine capable of cutting patterns

The Plan

• This project's focus is on implementing basic (though scalable) CNC functionality.

Progress

• Most of the Parts are ordered.
• The wood has been cut, but not fitted.
• Sourced Barrel Nuts locally
• Electronics and Steppers are in
• stepper/drive screw couplings ordered but not arriving til monday or tuesday
• table-top assembled (omg its heavy)

Next Steps

1. Lewters sells Barrel Nuts, so if the ones I ordered don't arrive soon - get some from there. (consolation: I didn't order enough anyway) (DONE - 26OCT10)
2. Put the Table together.
   1. X-axis
      1. 2'x 4' MDF sections bolted together (DONE 27OCT10)
      2. Rails attached (Rails Cut)
      3. Ends attached (holes drilled in 2x4s but not in Ends)
   2. Y-axis
   3. Z-axis
3. Get miscellaneous parts (Drive Couplings) (DONE 27OCT10)
4. Wait for the Control Equipment to arrive from China. (ARRIVED- 27OCT10)

Ideas

• I'll probably want to go with a belt drive system for the 4'x 8' iteration.
