Take a look at this site, toward the end of the first page and on the next page you will see how the router has a laser guide line to show you were to put the slab of granite to be cut. Any one see anything else similar that might possibly be incoperated in to Mach 3?

This will project you're g-code file onto your table. http://www.carterproducts.com/product.asp?product_id=16&cat_id=7

^^ That is one cool thing!! But there is no price on the site, so that means it's in K's.

Thats a cool unit. The problem is you need a bit table to get the gantry mechanism out of the way as it projects the image.

Maybe someone will come up with a projector conversion post one day on CNCZone

What about the things that were used in school a long time ago to put on the overhead projector to dipslay the computer screen on the wall?
Any one know what they are called?

transparencies?

Hmmm...let's see...I graduated high school in '80 and at that time there were still no 'puters in my school system. So that would be, what, a long, long, long time ago? We really did use transparencies back then! And we were darn happy we didn't get those stinky blue mimeographed copies. Whew! Now that's old! You young whippersnappers...'puter this and 'puter that.

O.k, silliness aside, your thinking of the LCD screens that set atop the overhead and displayed the whatever was on the PC monitor. Today there are some real small, relatively cheap, consumer LCD projectors too.

Generally the aspect ratio kills the accuracy of displaying the LCD onto a CNC table.

Ovation is the brand of the ones I have. I have several of the panels. Always called them "lcd computer projection panels" every time I found them on eBay...and they always came up.
