Hi Belin, I've used F Engrave, great for engraving text, especially in a curve or round shape, however only using G01 coding makes the program file very long. I save them as a G code then use Mach's edit function to get rid of the rubbish at the start, then the replace option to change (change all) the Z#1 with a specific value and remove any text Mach doesn't recognise. As far a jpeg files its a bit of a pain. I load them into my photoshop option and save them as a .PBM file, this seems to work, however it very much depends on how the original drawings were constructed, Mach thru F engrave is very unforgiving on how you constructed your drawing and misses out bits it dosen't understand. If you have not constructed your drawing in a logical way the cutter moves all over the place and takes forever to cut. I find using the correct CAD packages much easier and less time consuming. I found when doing drawing you need to think about how your CNC machine will machine the component then do your drawing to match. Hope this helps. Jim
