SFX-100 build: I have a Win11 PC connected to an Arduino Leonardo controller and plan to have four linear actuators. I'm using SimHub and it connects to the Leonardo controller through USB. Leonardo is on COM3 in Windows. Tested connections this morning. Activated motion in SimHub. Performed an actuator test, with good motion on the single actuator connected. After the end of the test, SimHub lost connection with the controller. An error message appeared: "The semaphore timeout period has expired". I could not deactivate motion in SimHub. I could not close the SimHub app. I went to Task Manager and tried to end task. Only when I disconnected the controller from the USB did the task end. Something is hanging up SimHub's connection to the Arduino controller and not allowing it to shut down the connection or reconnect. Help
