Hey, Eugene. You can change between modules by using one of two methods. (1) turn off the touch sensor on the joystick and swap the modules and then do a normal probe change through the select stylus option, turn on the touch sensor back on the joystick (2)If you want this step in a program go to the CMM pull-down menu and select Touch Trigger and click off, then from the PRB pull-down menu pick Select Stylus pick the stylus you want and click OK, go back and turn on the Touch Trigger, in the CMM pull-down menu. You will need to put a Pause statement in the program if you are in the CNC mode
