The trajectory is published on a topic. Every module publishes a new trajectory after it's done working with the trajectory. So for example if you modify the trajectory, the output of this operation will be the full trajectory (`ram_msgs::AdditiveManufacturingTrajectory` type) being published on the `ram/trajectory` topic. All you need to do is create a subscriber that listens to the trajectory topic. Each time a new trajectory is generated, modified etc.. you'll get a new message containing the latest trajectory. --- [Visit Topic](https://discourse.ros.org/t/ros-additive-manufacturing-ram/3170/17) or reply to this email to respond.
