So, convert -crop 594x774 halgraph.svg halgraph-%d.png Then; lpr -PHL3170CDW halgraph-*.png And I got 12 pages too. But something scaled it down from 72dpi to about 130 so the usable image per page was only 4.65" wide, so I had a lot of trimming to do when putting it together. And next time I can scale it down a bit, it would still be plenty readable on 3 edge spliced portrait images. And, I just now, 40 minutes later, got it cut out and taped together, but the last, lower right hand page has the image clipped about 2.5" worth on the bottom. So I ssh'd back into the lathe, ran inkscape, which puts a top and left marker on the image, and its that portion of the original image that is below the inkscape vertical scale bar's 0.0, but a small amount of the image is actually below that line. The missing bit feeds my pyvcp tachometer. NBD. So, I have something that while a bit fragile, does show what I have carved up in that file. Complex for a machine with two axis's and a servo controlled spindle plus an electrical probe kit for home all use. But if I have any dead ends, they aren't shown because rockhopper ignores "wires" that aren't connected on both ends. That "trash removal" could be a disadvantage as that was one of the things I wanted to be able to check quickly. Thank you very very much Kent. Hows the missus?
