## Resetting the Guide Point in Center Guiding with SCU6x Controller

 This video explains how to reset the Guide Point in Center Guiding using the SCU6x Controller. It demonstrates the process of center guiding with two sensors and showcases how to reset the guide point and adjust the offset. You'll learn how to manage the actuator direction changes and understand the reasons for allowing a guide point offset even when aiming for center alignment. This feature is particularly useful if the sensor was not installed correctly, providing a convenient alternative to physically repositioning the sensor.

## Transcript

One of the other things that I want to show with center guiding is that you can do the reset guide point just like what we did with edge or center guiding with two sensors. Let me show you that. Going back to the screen here, we have the web now and the green position indicates the center line position. If the web is moved that way and for whatever reason you need to do that, you could do the same reset guide point and accept.

Now the guide point offset is there. If the edge position goes on either side, the actuator changes its direction back and forth. This is for doing the center guiding with the point offset. Now, like I said, it's not usable for you to change the guide point offset with center guiding just because you want the material to be aligned to the middle of the machine.

The reason why we allow you to do that is that let's say you had not installed the sensor at the right location to begin with. Instead of going and physically moving the sensor, you could just move the offset. And that's the reason why we allow a guidepoint offset even when we do center guide.
