Symptoms We Resolve

Common CNC Router Faults We Diagnose & Fix

  • High-Frequency Spindle Inverter Faults

    Rectifying DC bus overvoltage, excessive braking current, and cooling fan interlock trips.

  • Axis Servo Drive Tracking Errors

    Eliminating positioning drift, encoder feedback loss, and axis motor binding across X, Y, and Z axes.

  • Vacuum Bed Hold-Down Failures

    Troubleshooting vacuum pump starter contactors, differential pressure switches, and airflow sensors.

  • Homing & Limit Switch Faults

    Repairing optical sensors, inductive proximity switches, and crushed axis limit wiring.

  • Automatic Tool Changer (ATC) Jamming

    Diagnosing carousel positioning sensors, pneumatic drawbar solenoids, and tool clamp interlocks.

  • Safety Light Curtain Lockouts

    Realigning optical safety barriers, troubleshooting muting sensors, and repairing dual-channel safety relays.
