Copter not descending in AltHold mode

ArduCopter Copter 4.5
1

Hey everyone,
I’m having an issue in that my quadcopter will not descend in AltHold mode, even if I lower the stick all the way. I’m using a Benewake TFMini Plus sensor for altitude. It will ascend perfectly fine and will hold its position vertically, but it won’t go down at all.

I just switched to the Benewake from a Mateksys 3901-L0X combined LiDAR and OpFlow sensor, and it didn’t work well, but… it did work. I wonder if there’s some parameter I didn’t change from one to the other.

I appreciate any help!

post your param file or .bin log file.

what are your following values?
PILOT_ACCEL_Z,
PILOT_SPEED_DN,
PILOT_SPEED_UP,

Probably related to TFMini config, best if you can supply a .bin log file
