Description
Having successfully reached key milestones of the SLS 2.0 machine upgrade and brought a first suite of beamlines into operation, the SLS 2.0 project has transitioned from initial commissioning activities toward large-scale beamline upgrades. Phases 0 and 1 validated core technical solutions and the controls hardware portfolio and implemented them on a first suite of beamlines. Building on this experience, the project is now entering Phase 2, an approximately 18-month effort in which nearly a dozen new end stations are targeting first light. A major component of this phase is the migration of beamline motion control to a new architecture based on the open-source EtherCAT Motion Control (ECMC) framework, enabling standardized solutions while supporting coexistence with legacy components where required. In this contribution, we review lessons learned from earlier commissioning phases, including the impact of compressed commissioning timelines caused by upstream infrastructure dependencies and limited resource availability. We describe migration strategies developed during Phase 1 and detail how these experiences informed improved documentation, workflows, and operational practices for Phase 2. Finally, we present new commissioning tools and automation approaches designed to scale deployment, improve reproducibility, and support efficient commissioning across multiple beamlines in parallel.
