I did this by just changing the sign and trying it. The program is small just 3 arcs so it doesn't take long just to check it this way. The next I did was just to change it to a linear move between the points and it worked fine. I just wanted to make sure the end points were correct. Then I started thinking it was setup with polar cord. I found another G code that would take it out of polar and put it in the line before the G2. Same problem. Im not sure what else I can try. The numbers all look good, I think im putting them in correctly. Any ideas
Are you using TNRC G41/G42 (Tool Nose Radius Compensation)?
Can you post your G-Code for us to look at?
Hard to say with out a Part or Program to look at. I have BCC V21 and NC Plot. Post a File if you are allowed.
