Advanced Centerline Recovery When Calibration Is Far Out

Use this advanced procedure only when a centerline is so far outside its saved range that the normal centerline-calibration workflow cannot be completed. Common causes include a power loss during movement, a lumber collision, an incorrect calibration entry, or position drift on an older screw-drive centerline.

Advanced support procedure: The Manual Controls screen can command full motor power and this procedure deliberately approaches a mechanical end stop. Keep the saw area clear and perform it only under Enventek Support direction. Stop the command as soon as the end stop is reached; do not hold the motor stalled.

Select the affected centerline

1. Open Repair → Manual Controls.
2. Select the saw head and the centerline that requires recovery.
3. Open Settings for that centerline. The screenshots use Centerline 5 as an example; select the actual affected centerline on your machine.

Establish the maximum reference

1. Use the Forward control to move the centerline carefully toward its upper mechanical stop.
2. Release the command immediately when the centerline reaches the stop and cannot move farther.
3. Record the displayed Motion Position. The example shown is 190.64; your value may differ.

Correct the saved maximum position

1. Open the Basic tab.
2. Compare the Motion Position you recorded with the Max Position field.
3. If the values do not match, use only the Set Position control associated with Max Position. Do not press the other Set Position control.

Move away from the hard stop

Return to the Calibration tab and use Back to move the centerline down from the mechanical stop. A short movement is sufficient. This step prevents the motor from beginning the next setup already stalled at the stop. The controls on this screen may use 100% motor power instead of the approximately 90% used by the normal cutting window.

Complete standard calibration

1. Exit the advanced settings after confirming that the centerline is within its maximum bounds.
2. Continue with Calibrate Retro C Centerlines 1–5.
3. Cut and measure a test board using the standard procedure.
4. Repeat the test and confirm that the measurement and return position are consistent.

If the centerline cannot reach the stop smoothly, the displayed position jumps, or the motor stalls before the mechanism reaches its limit, stop and investigate the drive, chain or screw mechanism, encoder, and wiring before changing calibration.
