Bobby, What's the image? A photo? A geometric shape? There may be ways to engrave a bitmap image with a rotary/drag machine, but the quality of the image and the running time will probably suffer. David "The Stunt Engraver" Lavaneri DGL Engraving Port Hueneme, CA

I myself do not know of any 'Rotary Engraver' that can engrave a bitmap.

All 'Rotary Engraver' are much like any Cnc, or Vinyl Cutters, they must have a 'Vector' file that is made up of 'mathematical coordinates' that can tell it where to move the cutter.

You can import a black and white bmp into XLG32. If you click normal view you can laser it as normal and it remains a bmp pixel file. If you click other settings it converts it to a series of horizontal but DISCONNECTED* lines that can indeed be rotary engraved. It does not create an outline of the graphic as usually is done to give it a smooth edge. So the edge can be rough depending on the quality. It does take a lot longer so it is only a good option for a few things if you don't have time to trace it. I really haven't used it in years. Before we had the laser we actually engraved a 8" tall photo of a building from a bmp. Since all the hatchlines require a cutter up and numerous lines it took 4-5 hours to do. But we hate to tell current customers it can't be done. A funny thing is after we got the laser, we just converted it to laser engraving since I thought it looked much better, not to mention the time difference. The customer rejected it and wanted it done the old way! O well 5 hours isn't that long. Luckily they only order 1 at a time. lj

What software are you using for the Vision engraver ? if it is Engravelab then it has a tool to produce a vector of your jpeg/bitmap image (look at help on Accuscan). Many other packages have this either as a standard function, or add on to the package.

Otherwise use Corel / Adobe Illustrator or a 3rd Party service as advised

Dr Engrave that comes with Roland machines has the ability to import a .bmp and cut it.

My first practice cut was a Cadillac logo that I saved from their website as a .jpg and converted it to .bmp

I thought it was pretty slick being a newbie to engraving.

If only my computerized mat cutter was as easy...
