3.2. Calibrating heads

Head calibration requires the system be set to maintenance mode and is typically performed during initial setup.

Before you begin

Tools and equipment required:
  • Calibration plate
  • Allen key: 2 mm
  • Valve mounted in each head position to be calibrated

Procedure

  1. If the system and laptop are not already connected and if the robot is not already homed:
    1. From the main button bar, click the Connect button.
    2. Click OK on the success prompt.
    3. From the main button bar, click the Home button.
  2. Set the Run/Maintenance keyed lock on the front control panel to Maintenance.
  3. If you’ll be calibrating a spray nozzle in either head position, manually unscrew the spray cap from the spray nozzle and set it aside.
  4. Slide the calibration plate into the work area on the conveyor rails until it is snug against the board stops at 0,0 position.

    2. CAUTIONCAUTION
      When either Calibrate Head button is pressed, the system immediately moves the gantry to the most recently taught calibration location. It first moves the X and Y axes, and then moves the Z axis.
      Ensure a clear travel path exists through the work area for both heads.
      Click Calibrate Head 1.
    3. Using the X and Y jog buttons, center the tip of the needle over the hole in the calibration plate.
    4. Using the Z axis jog buttons, adjust the tip of needle so it is positioned just above the surface of the calibration plate.
    5. Click the Set button.
    6. Click the OK button for each location prompt, and then select YES for the overall offset prompt.
    7. Use the Z- button to raise the needle upward, away from the calibration plate.
