how do I get a pixhawk to completely ignore pitch roll and yaw

[grimreeper132]

I am testing something and am needing to use a pixhawk, in order to do what I need to do, but I also need to get the pixhawk to completely ignore pitch, roll, yaw etc. so it doesn't try and correct for them, as that is being dealt with else where in the system, all I need it to do is try and increase it's height or decrease the height depending on what it is told to do. This doesn't sound hard to do, but I canny see how you do it within the mission planner.

I'm confused on what exactly you want to do, but if sounds like you want to bypass the PID controller on two axes of a multirotor. Is that correct?

pretty much I want it to only care about how high it is, and to completely ignore the pitch yaw and roll axis, shown below encase you know them by other names

Have you tried putting all the PID values to 0.

I tried doing that in mission planner and it seams to have minimum values which they can be set to, and I haven't looked to see if I can get them lower any other way

Exactly which aircraft are you dealing with? And what firmware?

I wouldn't say air craft yet, it's long and complicated, but pretty much I need only height control so it rises and falls and hovers when needed. The controller is a pixhawk 2.4.6, and it's ardupilot 3.5 I think (can't remember if it's called that, might be pixhawk 3.5, I won't be with the pixhawk till tomorrow now so canny tell you but it's one of the two)
