I would tend to use QCAD to draw concentric arcs and other cutter paths, use dxf2gcode to get the rough code, then test the code with simulated EMC2 to work out the bugs. I also have Synergy which will do the all of the path work automatically, but sometimes it's easier to use QCAD and dxf2gcode, because I end up having to work out code bugs either way. You can use g-code o-words to loop the concentric arcs, but I believe AXIS won't show the looped paths. This isn't essential, but I think using simple g-code (without the o fluff) is more true to its intent. I believe axes are supposed to be relative to the workpiece, so you need to pretend you are sitting on your part as it is spinning. If you see the cutter moving away from you, then it is moving in a positive direction. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Centralized Desktop Delivery: Dell and VMware Reference Architecture Simplifying enterprise desktop deployment and management using Dell EqualLogic storage and VMware View: A highly scalable, end-to-end client virtualization framework.
