# Endstop Calibration

The Endstop Calibration process ensures that your limit switches or sensors are correctly wired, configured, and functioning properly before running a homing sequence. Instead of using a G-Code command like M119, the Aurora interface provides a live view of the endstop status.

Objective: To verify that the endstops correctly report their state (triggered/untiggered) and that the wiring logic (Normally Open/Normally Closed) is correct.

  1. Navigate to the relevant Configuration Tab: Depending on where the endstop is configured, go to the Motors tab (for motors with individual endstops) or the Axes tab (for axes with a single endstop).
  2. Locate the Endstop Status Indicator: In the configuration panel for the motor or axis, there will be a live status indicator next to the Endstop and Endstop input type settings (e.g., a green/red circle or text displaying 'TRIGGERED'/'UNTRIGGERED').
  3. Perform the Endstop Test:
    • In the Untriggered State: Physically ensure the endstop is not being pressed or activated. The indicator should reflect the UNTRIGGERED state based on the configured Endstop input type (e.g., if set to Normally Closed, the indicator should show 'UNTRIGGERED').
    • In the Triggered State: Manually press or actuate the endstop switch/sensor. The indicator should immediately change to reflect the TRIGGERED state.
  4. Troubleshooting:
    • Indicator Always Shows 'TRIGGERED' or 'UNTRIGGERED':
      • Action: Check the wiring. The endstop might be incorrectly wired (e.g., signal and ground swapped) or the Endstop input type (Normally Open/Normally Closed) is configured incorrectly. Change the Endstop input type setting and re-test.
    • Indicator State is Reversed:
      • Action: If the endstop shows 'TRIGGERED' when released and 'UNTRIGGERED' when pressed, you must change the Endstop input type (e.g., from Normally Open to Normally Closed).
    • No Change in Indicator State:
      • Action: Check continuity of the wiring using a multimeter from the endstop to the Module I/O port. The endstop or the wire might be faulty. Wiring can also be done incorrectly, refer to our Endstop, Switches and Probes section.
