Tool changer logic
After all the axis of the machine has been homed as per the homing sequence the tool changer logic will
read the encoder data from Turret to get the current tool in position.
If a valid tool number is received then the current tool number is updated on the controller else an ERROR
message is displayed on the screen telling the user that the signals from Turret were not correct.
On a tool change request, MASSO will make the Tool Changer - Output 1 HIGH to turn the tool changer
head clockwise till the desired tool has been loaded in position. Once the tool is in position the Tool
Changer - Output 1 becomes LOW and Tool Changer - Output 2 goes HIGH to turn the tool changer head
counterclockwise for 1000ms to lock the tool in position.
