ROS Navigation - AMCL not transforming map to odom

edit

I am running a turtlebot 2 with an RPLidar instead of a Kinect, trying to get the navigation stack working.

I am unable to get AMCL to transform map to odom. My current tf tree looks like this: https://drive.google.com/file/d/0B-2f...

I am running two transform scripts between base_link and base_footprint, and base_link and base_laser. When I execute move_base.launch, I get the following error: [ WARN] [1500318096.546547244]: Timed out waiting for transform from base_link to map to become available before running costmap, tf error: . canTransform returned after 0.100719 timeout was 0.1.

In my launch file, I have: <include file="$(find tb2_2dnav)/launch/amcl.launch.xml" /> which references:

I'm not sure what I'm doing wrong and why AMCL is not transforming map to odom.

Edit:

This morning I noticed that I also get this message: [ WARN] [1500393926.336248116]: No laser scan received (and thus no pose updates have been published) for 1500393926.336100 seconds. Verify that data is being published on the /scan topic. I verified that the /scan topic was being published to and that the base_scanner was connected in my tf tree.

I also received this warning: [ WARN] [1500394267.315925339]: MessageFilter [target=odom ]: Dropped 100.00% of messages so far. Please turn the [ros.amcandl.message_notifier] rosconsole logger to DEBUG for more information. so I did as said and got:
[DEBUG] [1500393934.597976349]: MessageFilter [target=odom ]: Removed oldest message because buffer is full, count
[DEBUG] [1500393933.564483123]: MessageFilter [target=odom ]: Added message in frame laser at time 1500393933.356, count now 100
