@yagizzha thank you for reporting your problem and including the screenshots! This helps tremendously when trying to troubleshoot. From the screenshots it looks like the response from your machine is not in the expected format....except there is a bug in the code that doesnt print out what the response is. Give me one second and I will make a branch for you to test again and hopefully it will print out what your device response is.

@yagizzha could you go ahead and try this branch out and post a screenshot like you did above? https://github.com/flynneva/grbl_ros/tree/117-fix-status-print

I think we had forgotten to convert the status to a string before printing it out in an error message.

now the first part isnt working ,its receiving initial state then gives error

[flynneva]

@yagizzha could you include the command you ran in the screenshot?

Also, are you recompiling and sourcing the newly generated binaries with source install/setup.bash?

[yagizzha]

im running it with " cd dev_ws . install/setup.bash source /opt/ros/foxy/setup.bash . ~/ros2_foxy/install/local_setup.bash sudo chmod a+rw /dev/ttyUSB0 export GAZEBO_RESOURCE_PATH=/usr/share/gazebo-11 ros2 topic list -t" i use that on all new terminals , then for grbl " sudo chmod a+rw /dev/ttyUSB0

ros2 run grbl_ros grbl_node --ros-args --params-file /home/yagi/dev_ws/src/grbl_ros/config/cnc001.yaml

"
