We purchased a new PDJ Inc 5 Axis Router Machine which runs on a Mach 3 Controller. We are not sure if the Post Processor is to be programmed from the Tip of Tool or Center of Rotation of the head. We tried to reach out to the router seller and he isn't sure either. Is Mach 3 capable of supporting 5 Axis Machining from tool tip? Kindly advise.
