## Question

Can Roll-2-Roll handle multi-lane cascading alignment?

## Short Answer

Yes. Cascading configurations use each lane's edge position to set the guide point for the next lane, enabling edge-to-edge alignment across multiple lanes.

## Detailed Answer

Yes. Roll-2-Roll Technologies systems support multi-lane cascading alignment where each lane's edge position automatically sets the guide point for the next lane.

**Example configuration (14 lanes):**

- Each lane has two sensors: one monitors the "master" edge, one guides the web via a slave guide
- Lane 1's right edge position sets the guide point for Lane 2's slave guide
- Lane 2's right edge sets Lane 3's guide point, and so on
- Result: All lanes maintain edge-to-edge alignment automatically

**For faster response:** The [SCU6x](https://r2r.tech/products/sensor-controller/scu6x) controller's industrial Ethernet connectivity enables a central PLC architecture where any lane change can instantly adjust guide points for all subsequent lanes simultaneously, rather than propagating lane-by-lane.
