Why Your Stepper Motor Skips Steps at High Speed

Why Your Stepper Motor Skips Steps at High Speed You design a CNC router. You calculate the steps per millimeter. You write the G-code. The motor should move 200mm per minute. At low speeds, it works perfectly. At higher feed rates, it starts skipping steps. The machine cuts crookedly. You blame the software. You tune the steps per mm. You try different drivers. The problem persists. You have exceeded the torque curve of the motor. Not slightly. Fundamentally. Stepper motor internals — torque dr
