Tombstone Grinder
The Tombstone Grinder came to be when I decided that it was taking too long to engrave the epitaphs in my tombstones, witch I sell to help generate some funds to help with other prop building. The grinder is basically a light duty CNC mill, which is run off an old 486 PC's parallel port. All the motors with exception of the spindle motor are steppers which were salvaged from some old printers. The driver circuits I built using information from several sites which can be found here http://home.hccnet.nl/m.de.roode/ . My design is here.
Hard at work on RIP

To control the unit I used EZCNC available here
