Enter the Place Modulus value. This value represents the number of LED panels that will be skipped when placing the ArUco markers. This is useful for working on a large LED wall, where you would use over 1000 unique ArUco symbols if they were to be placed on every LED panel. The default value is 2. Change this to 1 for smaller LED walls where one ArUco can be displayed on every panel. Using the default value of 2 will place an ArUco symbol on every second LED panel.
