¶ Why Calibration Is Necessary
Calibration corrects systematic errors in the scanner to ensure accurate and reliable measurement data. Deviations caused by manufacturing, assembly, temperature, and environmental factors can affect scanning accuracy. Without calibration, the resulting pointcloud may contain systematic distortions, leading to inaccurate measurements, models, or assessments.
¶ Preparation
- Move the switch on top of the scanner to USB mode. Then, press and hold the power button to turn on the scanner.

- Connect the M1 Ultra to the computer using the USB 3.0 data&charge cable.
- Note: It is recommended to connect to a USB 3.0 port on the rear of the computer tower.
.webp)
Note: The end with the locking screw must be connected to the scanner. Tighten the locking screw securely.
Note: For a desktop computer, connect the USB 3.0 plug to a rear USB port for a more stable connection.

¶ Calibration Procedure
Identify the Calibration Board
- Aim the scanner at the QR code.
.webp)
- Click Calibrate in the bottom-left corner of the ELEGOO Scan interface.
.webp)
- Click Scan QR Code. Once the QR code is successfully scanned, the software will automatically proceed to the next screen.
.webp)
- Flip the calibration board so that the side with reflective markers faces up.

¶ Step 3 – Tilt 15° to the Right (Near Mode)
- Tilt the scanner approximately 15° to the right.
.webp)
- Maintain this tilted position and watch the computer screen. Slowly move the scanner until its virtual representation in ELEGOO Scan aligns with the physical scanner's position.
.webp)
¶ Step 4 – Tilt 15° Forward (Near Mode)
- Tilt the scanner approximately 15° forward.
.webp)
- Maintain this tilted position and watch the computer screen. Slowly move the scanner until its virtual representation in ELEGOO Scan aligns with the physical scanner's position.
.webp)
¶ Step 5 – Tilt 15° Backward (Near Mode)
- Tilt the scanner approximately 15° backward.
.webp)
- Maintain this tilted position and watch the computer screen. Slowly move the scanner until its virtual representation in ELEGOO Scan aligns with the physical scanner's position.
.webp)
¶ Step 6 – Vertical Position (Near Mode)
- Hold the scanner vertically.
- Watch the computer screen and slowly move the scanner until its virtual representation in ELEGOO Scan aligns with the physical scanner's position.
.webp)
¶ Step 7 – Vertical Position (Near Mode)
- Hold the scanner vertically.
- Watch the computer screen and slowly move the scanner until its virtual representation in ELEGOO Scan aligns with the physical scanner's position.
.webp)
¶ Step 8 – Vertical Position (Far Mode)
- Hold the scanner vertically.
- Watch the computer screen and slowly move the scanner until its virtual representation in ELEGOO Scan aligns with the physical scanner's position.
.webp)
¶ Step 9 – Tilt 15° to the Left (Far Mode)
- Tilt the scanner approximately 15° to the left.
.webp)
- Maintain this tilted position and watch the computer screen. Slowly move the scanner until its virtual representation in ELEGOO Scan aligns with the physical scanner's position.
.webp)
¶ Step 10 – Tilt 15° to the Right (Far Mode)
- Tilt the scanner approximately 15° to the right.
.webp)
- Maintain this tilted position and watch the computer screen. Slowly move the scanner until its virtual representation in ELEGOO Scan aligns with the physical scanner's position.
.webp)
- Wait for the scanner to complete calibration.
.webp)
- Click OK to finish calibration.
