I've done some backwoods digitizing by just manually moving the gantry using the arrow keys. It worked surprisingly well but was very tedious.
Thanks!
My dowel was steel. I actually just used an old 1/4" v-carve bit and just chucked it in my router upside down. The aluminum foil is grounded to the z-zero plate. When the metal dowel touches the aluminum foil, it makes a ground connection just like when you set your z-zero.
