Have you opened you SERIAL monitor after the program is uploaded successfully. Because When i execute the Position control, the motor doesn't rotate, but When i open the SERIAL monitor after the program is uploaded, the motors start to rotate.

Hi, @mkdy
The above terminal logs are normal.
Serial example is to output data in Serial, so check with Serial Monitor.
It is normal for the Arduino IDE terminal not to output any other data.

@jawad-tech @OpusK Thanks for the response!
Indeed, when I open Serial Monitor, I see Hello-World messages. However, I have to change port from /dev/ttyACM0 to /dev/ttyACM1 manually before opening Serial Monitor (otherwise Serial Monitor would not open, and that's weird).
At the moment I'm trying to start Dynamixel XL430 servo, but with no success. FindDynamixels sketch says that no devices are found. XL430 is powered via 12v5a power supply. Any ideas?

- First When you connect the usb from Controller to pc, you will check in ubuntu terminal 'lsusb` command to see your Controller IS connected to Which port. because Sometime there is a bug in an arduino port.
also try to make the port permissions by
'sudo chmod 777 /dev/ttyACMx Where x is your connected port.
and one other thing If you are using arduino IDE to Run the Code Its Ok,
Please check the SERIAL settings
- If using OPENCM Controller SERIAL bus1
- If using OPENCM and rs485 board then serIal bus3
+If open cr then SERIAL bus2
check your Connections of dynamixel to Controller or U2D2

Did you upload or reset the firmware with Serial Monitor open?
If so, it can be changed to a different name (eg. ACM1) by avoiding the device name already in use.
When uploading a reset or a sketch file, close the serial monitor window.
