This guide shows you how to set up the verification reflector for station verification, so the Dusty App can alert you if the laser tracker has moved or drifted during printing. If the tracker gets bumped, vibrates, or shifts in wind, your layout accuracy is compromised — the verification reflector catches this before it ruins a print.

What the Verification Reflector Does

The verification reflector is a physical target the laser tracker “checks in” with periodically while the FieldPrinter is printing. It serves as a fixed reference point that confirms:

• The laser tracker has not moved or drifted since stationing.
• The station is still valid.
• The tracking environment is still stable.

If the tracker moves — from an accidental bump, vibrations from nearby equipment, or wind — the Dusty App notifies you.

Prerequisites

• The verification reflector and its tape, found in the Accessories Case.
• A completed station (control points recorded and locked in).

Steps

1. Choose a location for the reflector

Place the verification reflector on a flat surface within 10 feet of the laser tracker.

Pick a spot where no one will step on or kick the reflector accidentally. Foot traffic that disturbs the reflector will trigger false alerts.

2. Secure the reflector with tape

Use the tape from the Accessories Case to fix the reflector in place. The reflector must not move during the print session — it is your fixed reference.

3. Point the laser at the reflector

Aim the laser tracker at the verification reflector until it locks on.

4. Record the verification point in the Dusty App

Record the verification point in the Dusty App in the Setup tab step (3), verify stationing. 

Verify It Worked

Once the verification point is recorded, the system periodically checks the reflector’s position during printing. You don’t need to do anything else unless the app alerts you.

If You Get a Tracker Movement Alert

The alert means the laser tracker is no longer where it was when you stationed. Layout printed after the movement may be inaccurate. Rerecord the verification point and reprint a line or object to check accuracy.

Common Issues

• False alerts: Usually caused by someone stepping on or kicking the reflector, or the tape coming loose. Re-secure the reflector and re-record the verification point. 
• Tripod vibration or sliding: The verification reflector detects movement but doesn’t prevent it. Station on a stable surface, always use the tripod base, and add weight to the tripod for friction if needed. Column/wall mounts and clamps are alternatives.
