feedback in emc2

I'm not sure that means feedback emc2.
Feedback is used for h-bridge or for motion control on the digital lineup.
Let us perform the following g-code G0 X0Y0, emc2 shows x = 0.00 y = 0.00, but the digital line shows the x = 0.06 y = 0.00; using feedback emc2 herself believes in the value of the line and finishing their need to position. I understand correctly?

Any servo system where EMC is part of the servo loop needs position feedback to
be sent to EMC in some manner. The scheme is that when the EMC interpreter
decodes the command for movement, the trajectory planner calculates a position
that is different from the current position. The PID routine computes the velocity
that is required, and sends a command for that to whatever interface commands
the servo amplifier to create movement. The PID routine monitors the movement
and adjusts the commanded velocity to minimize the difference between commanded
and actual position (the feedback).

Does this answer your question?
