I have been doing a bit more 3D work on the ShopBot recently. This is the total difference before and after after surface coal mining operations near Logan, West Virgina. I made this piece out of Wood before but thought plexiglas would be a better material. It took a little time to get up the nerve to cut into the 2" slab of acrylic. The roughing pass was about 1 hour.

Finishing pass - stepping over .0125" per pass, 2 hour run time.

Viewed through the bottom of the plex before bolting it back down to do the other side.
