    Machine backlash | High Power Media

    To eliminate backlash in modern CNC machines, positioning feedback devices are used with either rotary or linear encoders, often called scales. While the rotary encoder is still prone to backlash (compensated in software) the linear encoder is effectively blind to it, and the only machining errors are as a result of hysteresis in the machine.
