Then I would check the power supply in the enclosure. It should measure 36v. There is a pot you can adjust if it is not measuring 36v but in my mind, if that changed then the power supply is getting ready to give up the ghost. Or one of the motors is getting ready to fail.
I would be surprised if that caused the issues. You would have gotten some notifications from FireControl if it didn’t like something rather than misbehaving.
