it does not matter. if you home your machine,  it still has to move to the home switch and homing will zero the DRO

You can use the tool to export the drive sii file, then modify it to disable eoe and then flash it back

im using the EC500 motion controller with remora firmware.

im using normal stepper motors nema23 1.8deg with DM556 driver. (without encoder)
my maschine has dual y motors: XYYZ (gantry is woking good)

 
 

 

More info, please
Is there any feedback to LinuxCNC from the motors? Encoders? Glass scales? Resolvers? Anything?
What controller board?
Is it parallel port?
What is wired to inputs?
What drives and motors?

It would be much easier for you and for us if you skip the secrecy and just tell us what do you want to achieve, usually there are more than one way of doing things in LinuxCNC as it is very flexible.
Changing the scale is not good/safe/smart as noted above, but moving stuff more/less while the program is running is easy using external offsets.

only in my comuter they are "jumping" to another position (my motors are not moving) and its a larg number like almost 300mm in x and y axis

You mean I need to write a hal command (setp) in my python code?
and to avoid errors I need to restart the linuxcnc after changing that parameter, right?

I don't think there is a way to write from LInuxcnc to the MPG Screen. I think it must use the USB for that.
As far as the wiring goes, the circuit diagram on the receiver is all you need as each part is a seperate set of pins.
The estop is designed to be standards based with two redundant circuits but it works for a single sided estop as well.
You used to have to ask for a 5 volt encoder for mesa but now I think there is a switch to select between 5v and 24v on the board.
I always have used the digital I/O for axis and jog speed select to save pins (with a MUX8 or MUX4)

This recent config I did uses the same pendant and there is a seperate hal file and also a custom component to manage the three jogging buttons

Thank you for the recommendations.

The motors have integrated drives, and plugs at the motor end (and the junction box they plug into), so swapping them out is trivial.

I was trying to minimize the number of wires from the junction box to the board, but I get why some of the benefits aren't worth the drawbacks. I hadn't even considered voltage drop, actually. Good point!

Here's a modified wiring scheme:
