 We modified a machine that was partly assembled in our lab.  It has an aluminum frame, 2 stepper motors for the x axis, one stepper motor for the Y axis, and a servo to make a simple up and down movement in the Z axis.

 We designed combs parametrically in Grasshopper (thanks for the help Eduardo!) so we could easily make different combs with different width and spaced teeth.  We designed and cut legs for the machine on the laser cutter.

 The electronics are run by an arduino uno with a shield.  We create a drawing in Inkscape that is a path for the movement we want, then use a plug-in (gcodetools) that creates a generalized gcode for the path.  GRBL then changes the gcode into commands that move our machine.  GRBL firmware is loaded into the arduino, the arduino takes GCODE from the PC and converts it into movements of the stepper motors via GRBL.
