1

Hello Everyone,

i have experienced and issue with my y6b while use sb2 parameter

Setup is y6b here2 can mode tmotor 3508 blhely esc 14x14.8 prop cubeblack

attached the two short log

the first use use
EK2_IMU_MASK == 7
INS_USE == 1
INS_USE2 == 1
INS_USE3 == 1
INS_FAST_SAMPLE==5
vibeclip2 are present
vibe2clip.bin (2.2 MB)
The second one

EK2_IMU_MASK == 4
INS_USE == 1
INS_USE2 == 1
INS_USE3 == 0
INS_FAST_SAMPLE==1
vibeclip2 are not present
no-clip.bin (1.8 MB)
Why is clip on third IMU ?
The drone seems to be better tuned and need only COMPASS_MOT
attached also a frame photo

IMU3 is the “truth IMU” it is not isolated

So this is all good and normal

Thanks @philip for you reply
is safe to use second config or not recommended ?

Not recommended. It’s hiding real data. Hiding issues doesn’t make them go away

@philip as i read here with:
EK2_IMU_MASK == 7
INS_USE == 1
INS_USE2 == 1
INS_USE3 == 1
INS_FAST_SAMPLE==5
as you say:
IMU3 is the “truth IMU” it is not isolated
So this is all good and normal

This means that on a relatively low vibe machine, seeing clip2 rising would be normal?
So on a 10min flight with Clip0 and 1 being zero and clip2 going up to 151 is normal?

Nothing in that concerns me at all
