I have just bought a bridgeport romi ezpath lathe, I am missing some pages from the programing manual. I have been teaching myself and making fairly good progress, I am trying to figure out if I can change the part offset for all the tools at once, like when i put a new part in the chuck I want to just touch one tool off on Z axis and have all my tools offset, also when you thread a part can you go back into edit mdi and change depths of thread or rpm and still be able to pickup the thread it seems like when I make these changes the tool is just a little bit off. any help or info where i can get the rest of my manual would be great thanks.
