1. This is windows based code, so this is the wrong list. We may have heard of the name, but its safe to say we know relatively little about it. 2. In the GCode summary of the above pdf document, I see no reference to G17-G18-G19, which select the plane of the arc(s) it will move in. 3. Based on that, its a safe assumption that this code is hopelessly broken for what you want to do. 4. You can download, from linuxcnc.org, a cd image that will not only install linux, but linuxcnc at the same time. It may take a few days to fine tune the install for your uses, and it may take a day or 3 to get linuxcnc configured to drive your machine, likely much better than the Davinci code ever could. A network connection is assumed for all the updating that will be required since that cd image is now nearly 3 years old. I have a cat5 to all of my machines. 5. All this assumes the DaVinci interface is through a standard parallel port interface. It or even specialized wide data path cards are the standard for driving machines in real time. Serial ports are way too slow, ethernet has latencies that can destroy precision, and usb is even worse. So give it a try, I think you will be pleased. And if you do have problems, this IS the list to bring them to. So in effect you came to the right list after all. :) > "http://www.google.com/url?q=http://support.technocnc.com/support/0049_G > CODE%2520STEPPER%2520DAVINCI.pdf&sa=U&ei=yGyyUo6bEZD7kQfL8oG4Dg&ved=0CB8 > QFjAA&usg=AFQjCNG9KI0a2ruQooY0rq5yVxaqd-XoSw" Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
