Read-out extruder stepper motor commands

Hi all,

For or application I want to write an extra Pythonscript in klipper for communication with our dispenser. The main problem we have is that we want to read out in the curruntly writen code when the stepper motor for the extruder should be activated at what speed. If we can find that and read that out at the beginning of our script than we can transfer that data and use the GPIO pins of our Pi to activate our syringe.

Does anyone now how to arrange this?
