How would one add codes for specific movements to happen before & then after the tool change routine in the M6Start file. What I am trying to do is this: I have a 17 tool ATC & it is working great. I want to install a vacuum shoe on the spindle, & I don't have room above the tool rack to accommodate this, so I would like to "park" the boot before the tool change occurs, then re-acquire it before the machining resumes. I have the mechanics and design of this done, I just need help integrating this into the macro.
