Getting Started with your Structure Sensor (Mark II)
Congrats on your new Structure Sensor! We're sure you're eager to start exploring Structure Sensor's capabilities. To help you get the most out of your experience, we've put together this quick start guide to help familiarize you with this advanced accessory.
To preserve the battery life of your iPad, Structure Sensor (Mark II) has its own internal battery. Charging your Structure Sensor's battery is simple: connect the charging cable to your sensor, and then plug the USB end into any strong USB 2.0-compatible device.
0.9A can usually be expected from most computers. 1.5A can be expected from most USB wall chargers.
A blue LED indicator on the Structure Sensor's glass face will pulse when your Structure Sensor's battery is charging. As soon as your battery is completely charged, the LED indicator will stop pulsing and instead will stay on until you disconnect the charging cable.
In addition to connecting your Structure Sensor to any USB 2.0-compatible device, the USB Hacker Cable can also be used to charge your Structure Sensor and will charge the battery more quickly than the standard Power Adapter. USB Hacker Cables are available in the accessories section of the Structure Sensor Store.
Your new Structure Sensor (Mark II) is compatible with the original Structure Sensor type bracket. However, you need to use the new screws in the Mark II box, not the ones from the bracket box or the older sensor.
Attaching your Structure Sensor (Mark II)
Structure Sensor (Mark II) uses new, shorter screws to attach to iPad Brackets.
Do not use the longer screws which came in the iPad bracket box, or else you may damage your sensor.
In addition, please do not over-tighten the screws.
Additional Structure Sensor (Mark II) Accessories
A Bracket Adapter comes pre-attached to your sensor. Please keep it attached.
Thanks to this adapter, all iPad brackets for the original Structure Sensor will be compatible with your Structure Sensor (Mark II).
Remember to use the USB cable in your Mark II box to charge your sensor before use. Any standard USB port will work.
Supported models: iPad Pro 11-inch (1st Generation), iPad Pro 10.5-inch, iPad Pro 9.7-inch, iPad (5th, 6th & 7th Generation), iPad mini (4th & 5th Generation), iPad Air (2nd & 3rd Generation)
Precision Bracket with Aluminum Latch
Customers who have purchased Structure Sensor for iPad from Amazon.com can skip to Step 2.
Using the included screwdriver and screws, attach Structure Sensor to the supplied bracket.
Place Structure Sensor in front of the bracket, and then use the supplied screwdriver and 4 screws to attach the two together.
The data and charging ports on the Structure Sensor should be facing to the left as you look at the Structure Sensor and bracket.
Pictured: The proper orientation for the Structure Sensor is to have the two data ports facing to the long side of the bracket.
Step 2 — Attaching the Structure Sensor and bracket to your iPad
To attach the Precision Bracket with Aluminum Latch to your iPad, start by sliding the bracket plus Structure Sensor onto the top of your iPad, making sure that the aluminum latch is in its open position.
Left: Sliding the bracket on an iPad Air 2. Right: The bracket firmly seated.
Pictured: The bracket's iPad camera hole centered around the iPad camera.
As soon as you have firmly seated on top of your iPad, and you have ensured that the hole in the bracket is centered around the iPad camera, close the latch by pressing down on it with your thumb.
Step 3 — Attaching the Lightning cable to your Structure Sensor and iPad
Connect the supplied Lightning cable by connecting it to your Structure Sensor first.
Left: Plugging the Lightning cable into the Structure Sensor. Right: Plugging the Lightning cable into the iPad.
As shown in the above images, the wider end of the cable connects to your Structure Sensor, and the gold-colored pins should be facing up as you plug it into the Structure Sensor. Connect the other end of the cable (with the Apple Lightning connector) into your iPad.
Your Structure Sensor is now connected to your iPad!
Connecting your Structure Sensor to your iPad Pro
1-1. Remove your 3rd party case from your iPad Pro, if applicable. On a clean, flat surface, place the iPad Pro face down into the Bracket Alignment Tool as shown below.
Note: Make sure the iPad Pro camera is in the corner as shown here.
1-2. On the back of the Bracket, peel the backing off from all three adhesive pad pieces as shown.
1-3. With the iPad Pro still seated in the Bracket Alignment Tool, position the Bracket at a 45 degree angle into the Alignment Tool. Make sure the Bracket is aligned with the two edges of the Alignment tool. Once aligned, slowly press the Bracket completely down on top of the iPad Pro.
Note: Make sure to keep the Alignment Tool pressed up against the iPad Pro when attaching the Bracket. This will ensure a good alignment. If the Bracket is misaligned, slowly peel it up and try to align again.
Tip 1: The edges of the Bracket should be in line with the edges on the iPad Pro in three places (as shown below). This will ensure a good calibration of the Structure Sensor.
Tip 2: The camera should be centered in the opening on the Bracket.
Tip 3: When the Bracket is assembled on to the iPad Pro, wait 5 minutes or so to allow the adhesive pads to fully grip on the iPad Pro.
Step 2 – Attaching Structure Sensor Base Plate
2. Using the four screws and the screwdriver you received with your Structure Sensor, attach the Structure Sensor Base Plate to your Structure Sensor. The countersunk holes for the screws should be facing out when you attach the base plate.
Step 3 – Attaching Structure Sensor to the Bracket
3-1. Line up the Structure Sensor over the Bracket.
3-2. Slide the Structure Sensor down until it snaps into the Bracket.
Tip: If you angle one side of the Structure Sensor into the Bracket first, the other side will easily snap in.
Removing your iPad Pro Bracket
1. To remove the Bracket from the iPad Pro, slowly peel off the Bracket from the top two edges until the Bracket comes off.
2. After removing the Bracket, the adhesive pads will still be on the iPad Pro. The adhesive pads come off easy leaving no marks by rolling from the edge of the adhesive pads with your finger.
Reattaching the Bracket
1. To reattach the Bracket to the iPad Pro, go back and follow Steps 1 - 4 again.
2. If new adhesive pads are needed, you can buy it at most stores. Look for 3M VHB Clear Gel tape which comes in a 1” wide roll with red backing.
3. Here are the suggested places to apply the adhesive pads. It is also suggested to use three pieces of the VHB tape.
Step 1. Attach bracket to Sensor
Use the screws provided with your Structure Sensor (Mark II) to attach the sensor to the bracket. Note: be sure not to overtighten.
Step 2. Attach bracket to iPad Pro
Position bracket as shown. Slide bracket onto iPad slowly by pushing down. Make sure the bracket is seated against the iPad edges.
Next, if you're interested in developing your own 3D scanning software, you’ll want to sign up for the Developer Program to access the latest SDK.
Structure SDK is now available on iOS for the original Structure Sensor and Structure Sensor (Mark II). If you have already signed up for the Developer Portal and you need to retrieve your invitation, you can do so here.
