I have an older Kira mill that has been running the same production parts for close to 20 years. Last week it decided to quit using tool radius comp while cutting contours. I couldn't see where anything had changed in the program but loaded in one that was working in the mill next to it and still no radius comp. I compared parameters related to tool radius comp and saw no difference between the two mills. I have tried everything I could think of and most things google told me to try. I need some help with this one. Here is the program: %
