NVA Quick Start

This guide walks you through alignment with NVA – Nozzle Visual Aligner in a few minutes.

Advisory

• Review the full User Manual or watch the tutorial video before operating.

• Use the cutting head’s red guide light only during alignment—do not apply cutting power.

• Follow your site’s laser-safety procedures and all local regulations.

Overview of the NVA

1. Unbox NVA & Power Testing

• Open the box and take out the NVA.

• Open the battery compartment on the underside of the NVA.

• Insert two 14500 Li-ion batteries (3.7 V each), observing (+/–) polarity.

• Close the compartment.

• Press the power button to turn on the NVA; confirm the status LED lights on.

[Do NOT use AA alkaline/NiMH cells.]

No 14500 batteries?

Connect the included USB-C cable from the NVA to a power bank or power adaptor (5V/3A), then press the power.

2. Before you start

1

2.1 NVA Pre-alignment Preparation

• Power on the NVA and confirm the status LED is steady.

• Place the NVA horizontally directly under the laser cutting head; placing it on a metal sheet is recommended.

• Check the built-in bubble level is centered. If the unit isn’t level, shim the appropriate corner(s) (e.g., with paper) until level to avoid affecting alignment accuracy.

2

2.2 Laser Cutting Head Preparation

• Adjust the laser head Z-axis so it is positioned around 10 mm above the NVA.

• Install the dedicated alignment nozzle (included with the NVA package) onto the laser cutting head.

• Turn on the cutting head’s red guide light and ensure the red dot fully enters the central.

**Safety Notice**

Keep cutting power disabled at all times; align using the red guide light only. Follow site laser-safety procedures.

Connect Your Phone

1. Open your phone’s Wi-Fi settings and select the network NVA-[Serial Number].

2. Tap Join. Password: 88888888 (eight eights).

3. Once connected, open the alignment interface in either of the following ways:

Method 1 — Enter URL

Open your browser and go to http://192.168.0.1:8088.

Step 1 — Capture Nozzle (Red Guide Light OFF)

• Open the NVA lens protective cover.

• Turn OFF the red guide light.

• Adjust the nozzle height until the nozzle image is sharp.

• Tap “Step 1: Capture Nozzle (Red OFF)”.

• Indicator: When alignment succeeds, a yellow crosshair ring will appear, as shown in following image.

If not shown or unstable: adjust the cutting head position or reposition the NVA until the yellow corsshair ring appear.

Step 1 completion criterion: The yellow alignment ring—and its center—are perfectly concentric with the nozzle center.

Step 2 - Adjust Red-Light Focus (Red Light ON)

• Turn ON the red guide light.

• Tap “Step 2: Adjust Red Light (Red ON)”.

• Adjust the red-light focus value in the software—recommended presets -5 mm, -10 mm, -15 mm—until the spot becomes stable, with concentrated brightness and a sharply defined circular edge

If the alignment image is unclear, check the NVA lens for dust. If cleaning is needed, use a dedicated laser-head cleaning kit only.

Step 3 - Manual Coaxial Alignment

• Tap “Step 3: Coaxial Manual Tuning”.

• Use the coaxial adjustment screws on the cutting head to align.

• Alignment is complete when the red-dot center coincides with the nozzle center (rings/crosshair concentric). (Auto mode) Coaxial alignment is complete when the diff_X and diff_Y indicators in the top-right of the screen both read 0.

Step 4 - Finish

• Remove the NVA device and power it off.

• Remove the dedicated NVA alignment nozzle and reinstall your original nozzle.
