I was hoping someone might be able to answer a question. I am putting 6 limit switches on my mill, One for z -,one for z+,x-,x+,y-,y+. I am also using turbo cnc4.I want to put a override switch in line with all said switches. This way, when i have an over travel condition i can override it without killing power to motors. I also want to use same switches for homing in the future when turbo cnc supports this. I know i need to take one leg from each switch to the override switch but how do i keep the signal that is going back to the port seperate? If i put all 6 legs to the switch then the port will see any switching activity as coming from all the switches and i want to know what switch was tripped. Just one more problem, The turbo documentation states that pins 10,11,12,13, and 15 are input pins. Thats 5 pins and i have 6 switches. Help!!! Am i making this to complicated? Do i need to find a switch that has 6 isolated poles in and out? thanks for any help any one can shed on this.
