The 3 volt battery slot if for the RTC, real time clock. I suggest you read the Pokeys 57 user manual. https://www.poscope.com/wp-content/uploads/downloads/Pokeys/Manuals/PoKeys%20user%20manual%20(19.8.2017).pdf

If you have too much signal noise use a digital encoder for FRO as mentioned above.

On page 101 there is also a diagram for filtering the analog signal.
Apparently mine is not an isolated case.
The full control of the CNC (FEED+RAPID) is obtained only with a potentiometer, it is like opening/closing the tap on the sink.

I noticed that the Pokeys is very delicate and sensitive to disturbances from the electricity network.
so I tried to power with a battery, to have isolated power.
it works very well that way.
the system is very responsive and fast.
I made a short video.

now I have to find a way to effectively feed the Pokeys.

I tried as you advised.
Having servo drives, they tend to download spurious into the network, these are picked up by the Pokey.
The most stable system stays powered by a battery, but that was just a test.
I am convinced that if it had been a classic electronic stepper it would have created no problems.
