# Software connect problem after safety enclosure installed

After connecting the Arm with the safety enclosure, if you couldn't connect the Arm with Rotrics Studio: 

1. Please unplug the safety enclosure first, then reboot your robot arm. 
2. Send commands **M888 P1** to set the front-end module as laser module, then connect with the safety enclosure again. 
3. After the front end is set as laser module, the Arm can connect with Rotrics Studio without any problem.
