Adjust the parameters, the tool change time and lock time, try!
This problem is very simple, is not the command input, motor rotation, and the knife is like a rotation and stuck? This is just a tool conversion timeout, unscrew cap above the turret, turret removed, which has four pins, take out to see if bent, or flash, with the change of the pin, the pin can be used for standard parts can be, can not find it on 4mm head cut tail can be loaded
Open the cleaning to keep the knife holder into the garbage or not to check whether the motor is enough
