Overview

The reflector must be fully and properly seated in the cradle on the FieldPrinter for accurate tracking. If the reflector is not seated correctly, the tracker may read a slightly shifted position, which can affect stationing accuracy and print quality.

This article explains how to confirm proper seating and what issues can occur if it is not secured correctly.

Why Proper Reflector Seating Matters

The tracker calculates the robot’s position based on the reflector location. If the reflector is tilted, partially inserted, or not fully seated:

• Position readings can shift slightly
• Stationing error values may increase
• Printed lines may appear offset or inconsistent
• Verify Stationing may fail unexpectedly

Even small misalignment at the reflector can translate into visible layout deviation on the slab.

How to Confirm the Reflector is Fully Seated

Before stationing or printing:

• Insert the reflector straight down into the cradle without forcing it.
• Seat it flat and flush so the reflector base sits fully against the cradle surface.
• Position it between the two grooves on the cradle so it drops fully into place and is not sitting on top of either groove.
• Check for rocking or wobble by gently attempting to move it side to side.
• Visually confirm alignment from multiple angles.

The reflector should sit stable and level, with no visible gap under the base and with the reflector fully seated between the two grooves on the cradle.

Common Causes of Improper Seating

• Debris or dust inside the cradle
• Partial insertion due to rushed setup
• Cradle damage or wear
• Bent or damaged reflector mount

If debris is present, clean the cradle before reinserting the reflector.

What to Do if You Suspect Reflector Misalignment

If you observe unexpected stationing behavior or print deviation:

• Remove and reseat the reflector.
• Re-run Verify Stationing.
• If error values remain elevated, re-station using confirmed control points.

Correcting reflector seating often resolves minor but confusing layout inconsistencies.

Best Practices

• Check reflector seating during every setup, even if it appears correct.
• Inspect the cradle regularly for wear or buildup.
• Avoid handling the reflector roughly during transport or setup.
