I tried build 4.2.0.5036 in Lathe version.
I immediately noticed this problem on the DRO X wear offset.
it is no longer possible to enter the value directly.
plus this swings...

Hello.
I'm using a translator.
in my case it was our unsuitable wiring.
the signal cable was too close to the VFD power cable.
wires moved and shield electrically connected to earth.
everything worked.
the thread is perfect.

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.

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.

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 did further tests.
Powered with normal 5 volt switch.
changed ethernet cable.
potentiometer changed.
used short cable.
no result.
as soon as I power up the servo drive, the slide shakes.
to get sufficient stability I have to set the sensitivity slider all the way to the right.
consequently its control becomes slow and insensitive.
this defeats the purpose for which I bought this accessory.
request.
There is a 3-volt battery slot on the board.
what is it for?
I left blank.
Note.
potentiometer is connected correctly to pin 3.3volt.

Thanks, I did as you said and it works!
But now I have to solve a problem.
I explain what happens.
To do some tests on the fly I took these 5 volts from a PC USB socket (cut a common USB cable and use the red and black wires).
The board is normally powered with LED lighting.
I configure doors etc etc ... as usual .. nothing exceptional ..
I connect a potentiometer following the instructions...etc etc
so everything works...
let's get to the good....
as soon as i turn on the cnc servos, the potentiometer values start to oscillate...and the Mach4 slide wobbles..
I turn off the servo... everything returns stable...
other...
is it possible to add a digital shot? it is difficult to hit 100% with the potentiometer, it would be enough that from 98% to 102% the slide remains fixed on 100% is it possible?

Hello,
I bought Pokeys57E to pair with ESS.
I'm trying to configure potentiometer for the FEED (FRO%)
in the PLC scrip I don't understand what I have to write in this string, and the syntax
SetFRO(analogVal)
