Friends, I've been trying to use the Hokuyo Stack with a 04LX, following the tutorial, but when I start the hokuyo node, it complains about the laser sending "wrong data", and when I visualize the data via rviz, there are some lines, but definitely not what the laser should send. I can use the laser perfectly in other applications (Carmen, for example). Anyone knows what it might be? Thanks! Keep Creating, Pablo
