Good Morning All- I am new here and am hoping to participate in your community. I am self taught in drawing cad images, and self taught on waterjet as well. I was hoping someone could tell me how they were taught on this stuff? Did you go to university to learn cad and cam and machining, or were you also self taught? Also, was wondering if anyone had suggestions on what size tips to purchase if I wanted to engrave using the waterjet. We own a Mitsubishi 6x12 60,000PSI table. Right now we use .013 orifice and about 1 lb of garnet/minute, depending on material. I am curious to see if we would be able to engrave rock/marble using a smaller orifice/tip or less garnet and pressure. Any suggestions would be helpful. Thanks All!
