YAY! with a generous STEM grant from Utah we purchased a Zenbot CNC machine.  While we didn't have a lot of wooden parts this year we used it to make our electronics board as well as the "tombstones" that made up the ball pickup mechanism.  Students learned that the shortcut of using the "lazy CAM" software was no substitute for hand coding in gcode for the CNC.  One student is leaving a legacy for us too.  He is writing a program where we will just input our coordinates and cut depth per pass and it will generate the code for us.

 

Here's the router in action.

 

And here is a finished electronics board for the Andymark drive base complete with pre-drilled holes.
