When power is on, the gimbal wakes in a low-tuning state. The gimbal polls Astro for the lens information about the camera. Then, the gimbal selects the correct tuning parameters for the installed lens. Most uses will not need to change the gimbal settings from this default.
Users can run Autotune or set custom tuning parameters using AMC.
First, the user must enter Advanced mode by quickly tapping on the triangle icon in the upper-left corner of AMC. Then, the user selects Advanced > Parameters. Scrolling down to the bottom of the parameter groups, the user will find Component 154. Tapping the group expands the gimbal parameters labeled GMBL.
GMBL_TUNE_% sets the autotune backoff percentage; 50 is a good starting point. The user starts Autotune by setting GMBL_TUNE_START to 0.
Stiffness, hold strength, and motor filters may be set as required.
Set GMBL_LENS_ON to turn off lens-based tuning.
Set GMBL_PRMS_SAVE to 1 to write parameters to memory.
Set GMBL_PRMS_RESET to 1 to default all gimbal parameters.
Set GMBL_PRMS_SAVE to 1 to write parameters to memory.
Reboot Astro.
The reset procedure restores lens-based tuning.
If you have issues tuning your gimbal, reach out to support and we can help!
If you change the lens or add/remove an external module to the gimbal, go through the following steps to make sure the gimbal is configured to work with the new setup.
To balance the gimbal, first remove the lens cap from the lens.
Loosen the two finger screws on either side of the payload.
Move the camera forward and backward within the gimbal to achieve the correct balance. In general, you'll want to move the camera back for heavier/longer lenses and forward for lighter/shorter lenses. Shift camera foward and backward in the gimbal until the camera does not tip up or down when it is positioned horizontally and released.
To ensure the camera is very well balanced, test pointing the camera ~30 deg up/down; a well-balanced camera will not move in either of these two positions.
Once you achieve a good balance, tighten the finger screws so your camera stays firmly in place.
Loose screws can result in poor stabilization
With the gimbal already connected, power on Astro
The gimbal may have weak motor power for up to 30s on bootup, before the gimbal is reconfigured by Astro with different tuning based on the lens.
If you are using different lens or have otherwise modified the payload such that the default tuning isn't working, see the advanced gimbal tuning section
If you are using one of the four supported lenses, you shouldn't need to do this
