Error: EXBAR pins have a safety factor below 10, please use a different pickpoint!
This error message indicates that the safety factor of the pins which connect the top frame and the EXBAR is below 10. This commonly happens when pickpoints near the outer ends of the EXBARs or generally far away from the array center of gravity are chosen, creating huge leverage in the pins connecting the frame with the EXBARs. The safety factor of the frame is the minimum of the safety factor of the pins connecting the frame with the speakers, the pins connecting the frame with the EXBARs and EXBARs and their loads.
