I have a Sony A7iii with 28-70mm kitlens and a camera cage, weighing 3.6+ pounds all in all including battery and 2 SD cards inserted. My problem is whenever I calibrate the motors, after it calibrates, it shakes/vibrates continuously, like it cant carry the whole set-up even though Ronin S has a maximum payload of 8 pounds if I’m not mistaken. But if I don’t calibrate it it doesn’t shake. Any explanation why?
