I am not sure what you are asking about Pots ? the Center wire goes to a Pro Axis Pin ( I use leonardo's so assume the Pro is the same) you then assign the Pin under AXIS's in the MCU dropdown with the Source as IntSensor and assign which Axis you want it to be ie X,Y,Z etc. there is more info in the Wiki about it here :
Most of this info is also on my own Conversion thread too , seen in my Sig below, As a Noob to this stuff , I am trying to put all the good info in one place for people in the future now this thread is upto 128 pages.
Much appreciated Kbird. Sorry but missed that stuff on Axis. There are none so blind that cannot see !
Yes I plan to try the direct connect of Encoder to Pro Micro to test.
