interesting project ??
See please :
Video : "http://www.youtube.com/watch?v=sQF6VZBXfxE"]YouTube - ACMETEK CnC stone engraving router
1) Not new idea
2) Too expensive for tombstone business
We have our own hammer type engraver priced 3250 USD but due crisis we are selling 2-3 per month (compare with 10-12 per month in 2007)
3) Software is not very well done. From one side - not simple, from another - not powerful
