BASIC TAB
Stiffness setting has a significant impact on the performance of the gimbal. This setting adjusts the degrees to which the gimbal tries to correct for unwanted camera movement and hold the camera stable. The higher you can run the setting without vibration or oscillation, the better.
You can press the button AUTO TUNE twice or (3) times to find the best parameter.
Or by manual tuning: using your hand to touch on each motor. Start with 20 for each axes and then slowly increase this setting until you feel an oscillation in that motor, then reduce the setting until the oscillation subsides. Make sure there is no vibration when moving the camera in any orientation. Increase the stiffness, setting 5-10 points at a time until oscillation appears, then reduce 5 points until oscillation subsides.
STEP 01 - TILT STIFFNESS
Slowly increase this setting until you feel an oscillation in the tilt axis, then reduce the setting until the oscillation subsides. Make sure there is no vibration when tilting the camera up and down and when moving the gimbal in any orientation.
STEP 02 - ROLL STIFFNESS
Slowly increase this setting until you feel an oscillation in the roll axis, then reduce the setting until the oscillation subsides. Pick the gimbal up and make sure there is no vibration when you move the gimbal around.
STEP 03 - PAN STIFFNESS
Slowly increase this setting until you feel an oscillation in the pan axis, then reduce the setting until the oscillation subsides. Tilt the gimbal about 20 degrees from the verticality and make sure that no vibrations are present.
The purpose of the filters is to eliminate noise and vibration due to structural resonances in the camera, lens, or gimbal.
Setting the filters too high or too low can cause signal disturbances that can reduce the overall stabilization.
Defines the strength of the filter applied to Gyro sensor output. If the gimbal has oscillations that cannot be corrected by adjusting stiffness settings, the Gyro Filter is used to further tune the gimbal and remove the oscillation.
Defines the strength of the filter applied to motor output. If the gimbal has oscillations that cannot be corrected by adjusting stiffness settings, the Output Filter is used to further tune the gimbal and remove the oscillation.
If the gimbal is vibrating at a high frequency after tuning, increase the filter values.
If the gimbal is oscillating or rocking at a low frequency after tuning, decrease the filter values.
EXPERT TAB
If “Auto power adjustment” is enabled, “Hold strength” will be the minimum power level required for the corresponding axis. The controller will automatically adjust power level from minimum to maximum level depending on the displacement between the current angle and commanded angle.
If “Auto power adjustment” is not selected “Hold strength” will be constant power level provided to the corresponding axis and should be adjusted manually. This option is only recommended for advanced users.
NOTE: For heavy cameras, it’s suggested to increase hold strength for each axis around 10% than the default value. If “Auto power adjustment” is not selected, “Hold strength” will be fixed power level provided to the corresponding axis and should be adjusted manually. This option is only recommended for advanced users.
Default Hold Strength ( Tilt/Roll/Pan ) :
+ H series : 40/40/40
+ T series : 40/40/40
+ S series : 35/35/40
+ Pixy series : 30/30/35
You should keep it at default 120.
In case the vertical vibration occurs from the system, you can adjust the Gain to reduce it but please note that the gimbal cannot completely reduce this type of vibration. It depends on your system.
The Follow Tab in gTune Desktop is used to configure the Follow Mode of a Gremsy gimbal. Follow Mode allows the gimbal to smoothly track movements of the operator, making it ideal for handheld or drone-mounted applications where natural movement is required.
Follow Pan – Enables or disables follow mode for the pan (yaw) axis.
Follow Tilt – Enables or disables follow mode for the tilt (pitch) axis.
Adjusts how fast the gimbal reacts to movement.
High Speed: Gimbal reacts quickly to movements.
Low Speed: Gimbal moves more smoothly and gradually.
Controls how smoothly the gimbal transitions between movements.
A higher smoothness value results in softer, more controlled motion.
Lower values make the gimbal respond more directly.
Window
Defines the amount of movement required before the gimbal starts following.
A higher deadband reduces unintended small movements.
A lower deadband makes the gimbal respond to even small movements.
The Control Tab in gTune Desktop allows you to configure how the gimbal receives control commands. The available options—SBUS, SPKT, PPM, LB2, Herelink, and MAVLink—represent different communication protocols for controlling the gimbal from external devices like RC transmitters, autopilots, and ground control stations.
The IMU Tab in gTune Desktop is used to monitor and calibrate the Inertial Measurement Unit (IMU) of your Gremsy gimbal. The IMU is responsible for stabilization, motion detection, and orientation tracking.
Displays the current status of the IMU
Gyroscope & Accelerometer Readings
Shows real-time motion data.
Helps diagnose unwanted drift or balance issues.
When to Calibrate IMU and GYRO
After firmware updates
If you notice drift, instability, or vibration.
When operating in extreme temperatures.
Power on the gimbal and ensure it is completely still.
Open gTune Desktop and go to the IMU Tab.
Click Calibrate IMU.
Wait for the process to finish (do not move the gimbal!).
Once done, restart the gimbal and test stability.
Rotation Tab in gTune Desktop is mainly used to set the movement limits of the gimbal
Tilt Angle Range (Up/Down Limit – TILT)
Controls how far the camera can look up or down.
Roll Angle Range (Side Tilt Limit – ROLL)
Adjusts the range of side tilting.
This section allows you to fine-tune the motor offsets for Tilt, Roll, Pan, and Home positions.
It helps correct small misalignments in motor positions to ensure perfect stabilization.
Explanation of Each Setting
Tilt Offset (TILT) → Adjusts the tilt motor alignment.
Roll Offset (ROLL) → Corrects any roll axis misalignment.
Pan Offset (PAN) → Fine-tunes the pan axis center position.
Home Offset (HOME) → Adjusts the default "home" position of the gimbal.

Live graphing of angles, motor power each axis
System health check
Gimbal stays fixed in one direction no matter how the drone or operator moves.
The gimbal gradually follows the movement of the drone or controller.
Tilt Follow → Gimbal follows only tilt movement.
Pan Follow → Gimbal follows only pan movement.
Used for aerial mapping
The gimbal locks in a downward (nadir) position to capture consistent images.
Ideal for orthomosaic mapping with drones.
You can adjust parameters for mapping, home return, drift reduction, and pan axis behavior. Here's what each setting does:
Sets the angle for mapping mode
You can adjust it if your mapping requires an oblique (angled) view.
ON: The gimbal will automatically reset to a predefined position when the drone returns home.
OFF: The gimbal will stay in its last commanded position.
ON: The gimbal compensates for unwanted drift caused by drone movement.
OFF: The gimbal does not correct for drift.
ON: Allows pan-axis movement in mapping mode.
OFF: Locks the pan axis to maintain a fixed direction.
