What procedure did you followed to configure and tune this vehicle? Is this your first arducopter build? How sure are you that you did not miss a configuration step? How sure are you that you configured it using a correct sequence of steps that do not depend on a previously not executed step?
I did accelerometre, compass, ESC, and Radio calibration, set the parametres according to Benewake TFmini / TFmini Plus lidar — Copter documentation, for the lidar, i also set the setting in flight plan accordingly. After all, i’m pretty sure i did the steps correctly, but if there’s a mistake or unexecuted steps, please tell me about it
I think the copter is just following the terrian altitude as you configured. Maybe the range finder (TFmini-lidar ) is NOT working properly??? Have you sucessfully configured?
I just remembered that i haven’t done the tuning yet, should i do autotune to make it stable? By stable i mean it does not alternate that much around the setpoint altitude in the mission.
That’s not something you conveniently “just remember.” All of your questions are a bit moot until you follow the proper documentation and configuration steps…
