I think your right, Gerry. The K and Q values are not normally needed. The key is finding out what setting makes use of the I and J instead. Would be allot easier to troubleshoot it "hands on". Also, you need to make sure that you set the incremental/absolute mode in Machs "general logic config" within your g-code, instead of the check boxes. In the PP generators 'circle' tab, I would check the 'limit arcs to angle' check box, just to be on the safe side and avoid any potential unrelated errors that you don't need right now. When you get everything sorted and working right, you can uncheck it and see how it jives. Here is how a helix format could look, to give you at least some reference to go by.....

Also, when your posting a reply, there is an 'additional options' link south-west of the text input box, that will allow you to post your pics without the need to upload them to a separate server, and that mess. Use it if you like, it's much more convenient.
