I have had success with RedRock motors by doing the following. First thing when booting up MoviPro and Movi Controller, I load factory defaults on the fix axis config page for any motors I'm using, which is typically focus and iris. As long as I do this, and the motors are positioned on the sides of the lens barrel, and not wedged up against, (which I've experienced causes binding and faults) I've had pretty much flawless performance. It's irritating that I have to go through this process every time I boot up the gimbal, but I'm getting by for the moment. Does anyone at freefly have an explanation for why these settings aren't saved in memory when the units are power cycled?
