Hobby Hardwood channel mentioned that his Woodmiser hydraulics are switch activated. If this is the same with yours it should be possible to add a switch to lower either or both toe boards whenever you raise the log turner (just like the back stops already do). If the toe boards are already down nothing will happen. Check with Woodmiser first though.
Nice cherry and you were on your "A" game with remembering to lower the toe board 😁 In the overhead shots it looks like your adjustable guide pulley is askew, is it just the camera angle?
