Linear Encoder (Electronic Linear Scale) for CNC and DRO: A Practical Guide
Author: Nima Rad Short answer: A linear encoder, also called an electronic linear scale, measures the real straight-line position of a machine axis and turns it into an electrical signal. It feeds a digital readout (DRO) for manual machines or gives a CNC controller direct position feedback for closed-loop control, so errors from backlash, screw […]
