hector mapping before rplidar node?

edit

First of all, thanks for your future answers.

Why if I run the rplidar node before the hector_mapping and hector_geotiff launchers I get the error:

[ INFO] [1502821857.396404571]: lookupTransform base_link to laser timed out. Could not transform laser scan into base_frame.

But if I run hector_mapping and hector_geotiff launchers before run the rplidar node everything is fine and I get the map?

This is my hector_mapping.launch:

<launch>
<arg name="tf_map_scanmatch_transform_frame_name" default="scanmatcher_frame"/>
<arg name="base_frame" default="base_link"/>
<arg name="odom_frame" default="odom"/>

<arg name="scan_subscriber_queue_size" default="5"/>
<arg name="scan_topic" default="scan"/>
<arg name="map_size" default="2048"/>

</node>
