There are two possible reasons if the touchscreen shows 'the machine is not responding, would you like to reconnect' error.

• The controller may be faulty.
• The touchscreen itself may be faulty.

The controller may be faulty.

There is a breathing light at the back of the controller. Check whether the light at the back of the controller is breathing or not. If it breathes slowly, use a USB cable to connect the machine to a computer. In Luban software, try to connect the machine. The controller is fine if the Luban can control the machine.

If there is no breathing light at the back of the controller, the controller may have an issue.

The touchscreen itself may be faulty.

If Luban can control the machine, there is something wrong with the touchscreen. Try to unplug the touchscreen cable from the controller and plug it back at 180°, or shake the touchscreen cable. If the error message still exists, the touchscreen is faulty.
