Invalid I,J or K in G02 or G03 error

[wjrudo]

I am running a program generated on Solidcam 2007 r11 on the Haas VF6. The alarm says my endpoints don't match within .001 inch. I cannot find any settings within Solicam to tighten up the gcode, or on the Haas to loosen the requirements. I'm convinced it's in the Gcode someplace, but I have no support at the moment. I've tried to pick through the pre and post and change, what I would consider to be obvious choices, but I'm getting nowhere. I'll supply some simple code that gives an error if somebody will look at it and give me a direction. I'd like to get a Solidcam post from somebody. I know that's asking a lot. These things should be on the net in a huge datebase, but no. Any help would be great.

Post it here, we'll look at it.

The error happens in the last G3 move. I got rid of the rest of the code after it.

Try posting this in the SolidCAM forum. Maybe some one can help you there. I had the same problem with my VF2 and SolidCAM tech support changed my post processor to post in 4 decimal places instead of 3. The problem is caused by rounding I believe.

We have had this same problem on our VM-3 with NX5 posted programs but it's with only a .0001 difference. It is very random and only happens so often. I've emailed our Haas dealer asking about some sort of setting that would allow you to 'loosen' this so they didn't have to be exact. Our Fanuc guru at work said that there is a setting for this on our 15M controllers and I believe it is set to .001. I mentioned this to Haas but they weren't aware of any options. Haven't found a good way to fix this issue yet.
