No.
1. Before using the Z-Axis, make sure the axis lock on the base plate is unlocked and the Z-Axis is balanced. For balancing, please refer to the after-sales tutorial video Balancing.
2. To make the best use of the Z-Axis, try to hold the Ronin 4D upright during use.
Auto Calibration calibrates control parameters according to current payload, and eliminates accumulated errors of the sensor to ensure optimal gimbal performance. We suggest Auto Calibration any time after changing the lens, installing the X9 Focus Motor, or adding a counterweight, and re-balancing. During calibration, place the stabilizer on a level surface.
Make sure the gimbal and Z-Axis are fully balanced. Then, conduct Auto Calibration.
To use the LiDAR Range Finder and electric lens, we suggest using the X9 Counterweight (106 g) before balancing and Auto Calibration. If you are using a contactless manual lens, you can directly mount the X9 focus motor without the X9 Counterweight (106 g).
If tilt-axis jitter still occurs after the operations above, contact DJI Support for assistance.
Tap the gimbal balance detection icon and check the balance of the gimbal and Z-Axis.
If the balance detection icon turns yellow/red, calibrate the gimbal/Z-Axis according to the instructions.
After balancing, go to HOME - Stabilizer - Calibration and tap Auto Calibration to calibrate gimbal stiffness.

The actual operating and environmental temperature, number of existing files, and total bytes written (TBW) when using a third-party USB-C SSD can greatly affect the write performance. For accidents like frame loss or recording stops, please check the following:
1. Make sure the SSD is running within an appropriate temperature range. It is recommended to use it in a cool and well-ventilated environment and to use a metal frame with adequate heat dissipation performance to fix the SSD. Overheating can reduce the write performance of the SSD. For recommended operating temperature of the SSD, please consult the manufacturer.
2. Before using the USB-C SSD to record, make sure you have formatted it on DJI Ronin 4D. If the SSD is already storing many files written by other devices, the write performance may decrease significantly as affected by wear leveling and garbage collection algorithms of the SSD.
3. When TBW of the SSD is large, bad blocks can increase and significantly reduce the write performance. It is therefore recommended to use the SSD with smaller TBW when recording.
