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.

Thanks for the input.  Alright I edited the block format to what was suggested and that has eliminated the K word error but now I keep getting the error:

"Radius from end of arc differs from radius to startLine 10"

I've played with the tolerance settings but it doesn't eliminate the error.

I'm not sure how to change general config logic within the gcode instead of check boxes.

Just add G90.1 for Abs, or G91.1 for inc.   Since you've already got it defaulted to abs in the config page, you likely just need to add G91.1 to the code to make it switch to inc. See the code I posted earlier for an example.

I changed from "absolute" to  "vector from center to start" in the post processor and "incremental" in mach and here is the gcode:

I am no longer getting K word errors instead I'm getting:

"Radius from end of arc differs from radius to startLine 10"

10:X0.2186Y-0.7171I-0.1250J0.0000

which I think is progress because now we are just dealing with math errors instead of syntax.

I'm not sure how to deal with this problem though.  Adding G90.1 or G91.1 doesn't help

BTW, what the heck is G40.1?

It is 1/10 more than a G40 ;D ;D ;D ;D

That's usually an incorrect IJ mode.
If you changed it to what I said, you should need incremental now.

Attached is the current setting I'm using:

I'm still getting the error:

"Radius from end of arc differs from radius to startLine 10"

10:X0.2173Y-0.7175I-0.1250J0.0002

Adding G90.1 or G91.1 to the beginning of the code doesn't do anything.

Make sure you're using helical interpolation, and not spiral interpolation. It appears you should be using one or the other, and not both?

Looking at it again, I think it should be Vector from Start to Center.

Interesting.  When I change to "Vector from Start to Center" I still get the error. but when I change RhinoCAM to "Output spiral motions as linear segments" it outputs code in long form but Mach will read it.  I had heard that Mach does not do spiral arcs so could this be the issue?  Is that true?
