I have the Probeit probe and a generic z height setting tool.
Ill attached a picture of the z height tool and probe it that I am trying to use
I can not get both them to work without having to change the active low settings before using them.
If i go to ports and pins under probe with active low selected (green check) it will work. But the z height will not when I switch the plugs from one to the other.
If i use the z height i have to have active low disable (red x )and it will work but the probe won't.
Is there something i am missing or this combination will not work.
I am milling metals on the mill so not able to use a probe plate.
any help or a device that will work please let me know.
thanks
john

The Probe-it manual shows how to use it with an active low input.
See Section 2.1.2 http://www.craftycnc.com/download/154/
A resistor value in the range of 1000 ohms should work. The maximum value depends on the pull up resistor in your BOB input.
