I am adding a RADDS style hall effect sensor to my printer on the Z axis.
There is an option to use an external potentiometer to adjust the sensitivity of the unit instead of the small one on the board.
My issue is with wiring the pot, the directions show one wire being connected to the metal mounting shaft, but my pot has a plastic case and shaft....
I'm not sure what to do with that third wire!!!

Can anybody advise how I should hook this up?
Any replies are most appreciated.
Thank you,
Bryan
