Four-Corner Calibration

Calibrate your projector by aligning four points on your cutting mat.

Step 1

Choose your mat units

Choose whether your cutting mat uses centimeters or inches.

Step 2

Position the cutting mat

Place the mat inside the projection area outlined by IntelliSew. Adjust the projector’s height and position until the mat is centered and the projection covers the area you plan to use.

Step 3

Align the bottom-left corner

Drag the projected marker until it overlaps the bottom-left corner of your calibration area. Use the on-screen controls to make precise adjustments.

Step 4

Align the remaining corners

Repeat the process for the bottom-right, top-right, and top-left corners.

Step 5

Enter the width

Measure the distance between the two bottom corners and enter it in the app. When the measurement is correct, the projected vertical lines should align with the cutting mat grid.

Step 6

Enter the height

Measure the distance between the bottom and top corners and enter it in the app. The projected horizontal lines should now align with the grid.

Step 7

Refine the calibration

Check all four corners on the refine calibration screen. Select and nudge any corner that is slightly out of alignment.

Step 8

Finish

Select Done when the projected grid matches your cutting mat. IntelliSew saves the calibration, so you do not need to repeat it each time you use the app.
