i am learning 4 axis and i have a problem. when i use master-cam to make a rolldie tool path i get very slow feeds when using the a axis in all vectors, when x, z, or y only i get full feed. i know there is a parameter for the diameter, that changers the feed ratio to match the circumference. can someone help me figure this out? i am using a troyke model DL-9-8 rotory head on a viper 950-a running Fanuc Oi-mc. thanks
