RE: [CAD_CAM_EDM_DRO] Closed loop stepper systems

The software. Most software will via the encoder determine if the
stepper is out of position, if so it will add steps within a certain
setup parameter to catch up. If it is too far beyond where it can catch
up then the program stops the motor so the operator can correct the
problem. That is how deskncrt and emc work.

In a closed loop stepper system is it the responsibility of the
stepper driver or the software to correct for missing steps?
