i am currently using the rplidar A3 sensor on ROS2 Foxy on Linux. Currently, the sensor does spin, however, it only scans once and stops the process. It then states that there is a memory corruption in output terminal. Additionally, when i stop the program, the sensor continues to spin until I disconnect the USB cable. The USB port in used is dev/ttyUSB2 and the baudrate is 256000. i require assistance in solving this issue.

i have same problem. try open your rplidar_a3.launch.py and comment 17 line 'angle_compensate': True, or change to False this key

Setting angle_compensate False caused "shaky" scans, and I could not get slam_toolbox to work.
I switched to this fork, commented out M_PI in that source code, built, and it worked for me. I chose this fork based on this slam_toolbox_discussion

Hi!
I would like to point out that there is available a new repo from Slamtec here: sllidar_ros2.
According to my initial testing seems also working with slam_toolbox.
