In this episode, we explore how to utilize the center guiding feature of the SCU6x Controller with two sensors, focusing on automatic adjustments and setup. We demonstrate the mechanics of center guiding using an actuator and explain the importance of using sensors of the same range. With detailed visuals, we show how to reset the guide point and align the material to the center of the machine. Learn about the two primary reasons for using center guiding: managing variable web widths without relocating sensors and improving alignment quality when dealing with irregular material edges. We highlight the benefits of our sensors' broad range, which enhances system adaptability without the need for frequent adjustments.
