ITMx SUS - update
We've connected all of the cables on the ITMx QUAD and all 20 OSEMs have some sort of signal coming out to medm. Thanks Richard for some power and rack troubleshooting on QUADTST. There is some strangeness on the medm so Arnaud is looking into what model version is loaded on the QUADTST testbed. The main chain does not damp so we likely have crossed signals or a sign flip somewhere...? More from him to come.
Damping gains were still set to their old values. They are now set to -1, which is the convention for filter gains. Coilouput gains and signs have been checked, and are in accordance with the magnet convention (+ sign = north pole magnet, and vice versa).
