Troubleshooting Problems 

• When your drone fails to function properly, you must take a few measures to determine the cause.

• Some of the Major Troubleshooting Problems are:

1.  Drone Vibrations

Cause: From Hardware

• When the Propeller mount is mismatched with different versions of motor (x6 motor,x6 plus motor)

Solution: fit propeller mount correctly and verify every propeller mount such that every motor is having the similar mount

• When the Propeller Mount Is Not Good (including Washers should be there)

Solution: fit propeller mount such that each single prop is having washers above and below and tighten it optimally

• When the propellers are  differently  placed (with Stripes and without Stripes)

Solution: fit propellers carefully such that using same type of propellers and fixing 

• When Mechanical Parts are not tightly Fixed.

Solution: fit mechanical parts optimally

• When Arm Joints are Loose and also include motor leveling is not good.

Solution: fit arm joints ,motor level and check regularly 

• When there is dust in the Motors, Vibrations May occur also When the Motor is old

Solution: Check regularly  and rotate motor manually even one can hear noise while rotating manually then use blower to clear dust

• When Riveting is done aggressively if the motor signal wire got damaged.

Solution: Be careful while doing drilling

             Cause: From Power supply

• Motor Soldering is not good  

Solution: Be attentive while doing soldering

           Cause: From Software

• Need to check parameters like Motor Thrust power

Solution: Change motor thrust power by referencing other parameter file

• When Calibrations Is not Done Properly

Solution: Do all calibrations (RC, Compass, Accel, level horizon, barometer) properly

2.  Motor Not Working

Cause: From Hardware

Note: If 2 or more motors need to replace make sure you are fixing motors with same orientation according to the motor layout

• When the Motor Pin is not placed Correctly and Tightly. (Signal Pin and Power Pin) .If signal pin is not connected properly /damaged then you will get constant beeps respectively from that motor when safety is off.

Solution: Do check whether power and signal cables are connected correctly

• When there is a bent, dent in a motor  

Solution: Try to rotate motor manually if is having difficulty while rotating contact marut representative to change motor

• When Riveting process is done aggressively if the motor signal wire gets damaged. It can be observed that one can hear constant beeps respectively from that motor when safety is off.

Solution: Careful while doing drilling for riveting

• When there is dust in the Motors, also if screws are fixed more tightly (when it touches the winding).

Solution:  Check regularly  and rotate motor manually even one can hear noise while rotating manually then use blower to clear dust

• When the Propeller is mismatched with motor orientation.

Solution:  Careful while fixing propeller

          Cause: From Power supply

Solution for 4.3.2:

• Make sure of using height tuned param file i.e.,121 param file.(For service engineer)

•  If plant canopy is less than 1m than use altitude mode as terrain and C on and keep height(altitude) as 3m

•  If plant canopy is 1.5m than use altitude mode as terrain and C on and keep height as 3.5m

• From crop canopy 2m use altitude mode as relative and c off and keep height buffer as 3m so final height will be 2+3=5m and so on.,

     NOTE:  

• Make sure you are using the altitude mode as mentioned before

• After changing these then only upload the mission (where motor test will take place)

• Always use relative mode above 5.0m i.e., when crop canopy is more than 2m

• Make sure you are using max speed 4m/s as autonomous flight speed

15. Drone Takeoff ( it taking Yaw) 

   Solution for 4.3.2:

•    Make sure of using yaw tuned param file  i.e., 121 param file if not flash the parameters  (for service engineer)
