i want to improve my dust hood ,because i have many tool length ,i want to calculator the hood position
and stop it while go down exactly on its correct position
i do it with l valve that have 2 electric solenoid on 2 side and 3 position ,so "1" on 2 side mean stop the cilynder
i also connect encoder to the hood guide to count its movement
but i do not know how make cycle in mach to activate output ,wait until encoder reach position ,and when reach the
position activate the brake
thanks
