I need your advice, please (planar laser to 3D using encoder)

Hello everyone, I am using Neato XV-11 Lidar with getSurreal Lidar Controller v1.2 (Teensy 2.0). I have an Intel Edison (Flashed with Emutex's Ubilinux), and I am trying (unsuccessfully, but that's not the issue. though, tips are appreciated) to install ros_comm using http://wiki.jigsawrenaissance.org/ROS_on_RaspberryPi .I want to have the laser spinning (2D), have a motor spin the laser on another axis to get 3D reading and use an encoder to read the angle on the second axis which the laster is spinning. I want to connect the encoder directly to the teensy (Should it go directly to Edison? my concern is latency) and use this Encoder library https://www.pjrc.com/teensy/td_libs_Encoder.html to grab the information from the encoder, then implement odometry using tf in order to create a point cloud. I already have laser_assembler working, and have the laser_scan put into a buffer for 5 seconds, then have a point cloud published for rviz to read (done via a tutorial, don't have a link. you might know of it). But, of course, this just shows a point cloud of the "same" map stacked onto itself a few different times because I have no rotation being published (terminology problem?). What do I need in order to get the information from the second axis of rotation into the point cloud? I envision the laser taking about 5 seconds to make a full turn on the second axis, then having the 3D point cloud published every 5 seconds. I am sure there are a million holes in my plan, but that's why I come to the experts here at ROS. I'm new (+- 4 weeks) to ROS but have been studying ~40 hours a week to get this thing going. I have done the tf, catkin, and other tutorials from ROS so I do have a Beginner-Intermediate understanding of what's going on. I appreciate any tips, suggestions as to any part of my plan, or idea in general. Thank you in advance
