200khz USB bob upgrading to 4th axis

It looks to me like you connect the tip of the stereo plug to an input pin of the bob and the middle ring of the plug goes to ground. Rather than cut the plug off like they suggested I would get a matching socket, mount it somewhere handy and wire that back to the bob.

I have already got a socket setup for the probe as it was functioning properly with my previous motion controller board. Now I have swapped this board for the 5 axis BOB, it will not function. It is wired exactly as you just suggested

Have you tried connecting a mutimeter to it (on ohms range) to see if the circuit makes and breaks when the tip is moved ?

It needs between 3V and 24V passing though it to work

Yes that's to make the LED work but it should still have worked as a probe without the LED coming on

[dudz]

yes, as I said it was working right before I changed the bob

Still no luck

No it does not. The probe works though on my Motion control card
