What are the key steps involved in diagnosing and resolving a 'servo lag' error on a CNC machine?

Diagnosing and resolving a 'servo lag' error on a CNC machine involves a systematic approach to identify and correct the underlying cause of the positioning delay. Servo lag occurs when the actual position of a machine axis lags behind the commanded position from the CNC control. The first step is to verify the error. Ensure the error is consistent and not a one-time occurrence. Note the axis or axes affected by the servo lag. Next, inspect the mechanical components. Check for any signs of binding, excessive friction, or damage in the axis drive system. This includes inspecting the guidew....
