OK, cutting two profiles, the profiles are the same other than the length of the part. I am cutting these on a fixture, but both parts are not coming out the same. I looked at the g code and the second part is not using the same code as the first part (the first part is correct). Starting at line N235 the discrepancy start. The start of the radius X value is different, on the next line the I and J values are different. On line N241 there is an extra G02 move, this doesn't appear in the first parts code. Not too sure where the problem is, any ideas?
