Alarm Code 9 Homing Fail

Has anyone here with an NeJe Master 2S Plus run into the following error Message: Alarm 9 Homing Fail, Defined as 1.5* max_travel on search and 5* pull off locate phases? And do you have a fix. All of my belts are tight.

Is this new behavior? Do you have limit switches? If so, I’d check that they are working and wired correctly.
