Perhaps one of the more common questions we get from customers is "why is my gimbal drifting when it's powered on?." Obviously, a properly balanced and calibrated gimbal will stay put and only move when (and how) you want it to move.

A likely reason for the drifting is that the RC Sub-Trim settings may be off. The RC Sub-Trim is used to calibrate the Joystick. This is an electro-mechanical control surface that over time may need calibration for it’s true Neutral Position. The most common problem is slow ‘drifting’ of camera position. When the Joystick is not calibrated properly, the gimbal believes that someone is applying Joystick commands and starts to move. The video below will help you properly calibrate your joystick and thus likely eradicate the problem of drifting.

NOTE: If you're using a gimbal with an external wireless remote, then make sure the remote is turned on during this process.

NOTE:   After completing this process, if drifting persists on any 1 profile, but is no longer present on either of the 2 Profiles, then you can manually copy the RC subtrim values from the non-drifting profile onto the profile that does drift. In other words, after completing the Auto RC-Subtrim process, if Profile 3 still drifts, but Profile 1 & 2 remains still, then you can manually copy the RC-Subtrim settings from Profile 1 or 2 onto Profile 3. Drifting should then be eliminated from all 3 profiles as a result.

When you purchase a CAME-TV gimbal, chances are that it has been pre-programmed with 3 main profiles. And each profile contains its own unique set of follow modes, which you can toggle between depending on which mode you need to use.

Profile 1 will enable Follow Modes for both Pan and Tilt (Yaw and Pitch).
Profile 2 will enable Follow Mode ONLY for Pan (Yaw) and will Disable Tilt (Pitch).
Profile 3 will disable All Follow Modes. The Camera heading will stay constant.

However, in the event that these follow mode settings are unknowingly or mistakenly altered in the SimpleBGC software, you can manually restore them by dialing them in yourself.

Service Modes are used to assign button clicks to various gimbal operations. On most CAME-TV gimbals, you can toggle between these different modes simply by clicking on the service button (or joystick) to operate them. By default, the first three modes are set as follows:

1 Click: Switch to Profile 1
2 Clicks: Switch to Profile 2
3 Clicks: Switch to Profile 3

To see how Profiles 1, 2, and 3 are configured, click here.

It's also a good idea to take advantage of your Service Modes by using the Profile 4 and Profile 5 options. These profiles should specifically be set to calibrate your sensors and gyro, respectively. These modes will especially come in handy when you're shooting out in the field and don't have access to your laptop to recalibrate your gimbal.

4 Clicks: Calibrate ACC (Calibrate sensors. Must hold camera and gimbal level and square when using this option)
5 Clicks: Calibrate Gyro (Calibrate Gyros. Must hold camera and gimbal level and square when using this option)

Download the SimpleBGC software here.

SAMPLE: Once you have Profiles 4 & 5 programmed and saved, you can now calibrate your sensors and gyros directly through the gimbal. (Demonstrated in video below with a CAME-Single, but the process applies to all CAME-TV gimbals when calibration modes have been programmed in them.)

None of our gimbals currently come with a bluetooth module or support bluetooth connectivity with external mobile apps. Trying to install other third party modules into any CAME-TV gimbal may void your warranty.

For wireless control of your CAME-TV gimbal, you can use the CSWR-4 wireless remote, which comes free and pre-paired with the following gimbals - CAME-Prodigy, CAME-Argo, CAME-Spry, CAME-Optimus, and CAME-Prophet.

The CSWR-4 can also be used with the CAME-Single, but must be purchased as a separate accessory.

Brushless Motors can be wired to spin in clockwise or counterclockwise, and the software to control them can automatically change directions. Motors on Gimbals can also be mounted in many different ways, so the software needs to detect which way is the proper rotation for your setup. This is when you may need to use the Invert option under Motor Configuration.

Cametv Motor Invert configuration
IMAGE IS AN EXAMPLE. DO NOT COPY THESE INVERT OPTIONS DIRECTLY. FOLLOW INSTRUCTIONS BELOW.

Before starting this process make sure you have the Sensor Orientation setup correctly. This information is required when checking Motor direction. If you are unsure about your Sensor positions, check this article.

Once you have your sensors setup correctly, follow the instructions in the video below to determine if any of your Motors require the Invert option selected for your Gimbal.

We understand that many people want to Tune their Gimbals for different characteristics. But instead of downloading and sharing profiles, Keep in mind that Profiles carry several settings that are unique to your system. Instead of downloading and installing complete Profiles just for PID settings, we suggest just changing your PID settings manually through the software. This way you don't affect other settings such as Motor Invert Options, RC Settings, Sensor Positions, Follow Modes, etc.

If you have connected your gimbal via USB, you may need to install the proper driver for your Mac or PC to communicate with the control board which can be found Here>>.

Once you have installed the proper Mac or PC driver and restarted your computer, connect the gimbal, go into the SimpleBGC software, and on the upper left, select the proper USB port, and hit 'Connect'.

Connect-to-SIMPLEBGC-Basecam-32-Bit-gimbal-board

If you still do not see the gimbal or if you already have the proper drivers for your computer, please check your USB cable to make sure it is a Data cable. We suggest either testing the cable or just change the cable entirely to make sure it is not an issue.
Make sure the cable is fully connected to the gimbal and your computer, then restart the SimpleSBC program.

Setting up Sensor Orientation

[Note: It is important that you Calibrate your Sensors After Performing these instructions]

There are two sensors on the CAME-TV 7800 Gimbal. One is located above the camera frame, and the other on the vertical frame. These sensors will determine Right from Left as well as Top and Bottom. As your camera moves, the sensors will track the camera’s position. If the sensor is setup incorrectly the gimbal will be confused and cannot stabilize the camera properly.

For the CAME-TV 7500 and 7800 Gimbal, setup the proper Sensor Orientation for both Camera IMU and Frame IMU.

First click the Camera IMU Button and then change the values to
Axis TOP: Z
RIGHT: -Y

After making these changes, make sure to Save the Settings by clicking the WRITE Button on the lower right corner of the SimpleBGC Application.

Next click the Frame IMU Button and change values to
Axis TOP: Y
RIGHT: -X

To verify that these settings are correctly tracking your camera's movement, first click on the CAMERA IMU Buttong. Now Tilt your camera up (lens towards sky), and tilt the camera down (lens towards floor). View the Pitch Scope on the right side of the application. The Arrow should follow the camera's movements and the point of the arrow should indicate the lens direction.

You can verify the Roll of the camera by tilting the camera body 90 degrees on it's side. When standing behind the camera, the ROLL Scope on the right side of the Application should follow the camera's movements.

If you are unsure about which settings to choose for your Sensor Positions, this video by MrCheesycam explains how to use the Auto Detect Mode.

If you've received your gimbal, balanced your camera, and find the system works perfectly when panning Left or Right, but is not stable when Tilting Up or Down, double check if you've mounted the Camera Frame in the correct position. Take a look at the image below.

1_came-7800-gimbal

The Pitch motor (controls Tilt) should be located on the Left Side of your Camera (when standing behind the camera). If you have the motor on the right hand side, then the frame is both upside down and backwards. This will cause confusion with the sensor orientation as it tries to keep your camera level.

Surprisingly we receive several emails a week because of incorrect mounting of the camera. Most people will immediately start to change PID settings, and even attempt Firmware updates (not recommended unless you know what you're doing). Please double check this before attempting to modify any settings on your gimbal.

Configure RC Tab Settings - JoyStick Control Options

Connect to the Gimbal with a USB Cable and launch the SimpleBGC Software. For info about downloading and installing the software read this article.

rc joystick control settings
NOTE: The values above are shown as a sample only and may not pertain to your gimbal's unique RC settings. Do NOT copy them!

RC Options Explained

1.. The Joystick on the CAME-TV is a 2-Axis Joystick. This means it can control movements from either Pitch, Roll, and YAW. The default setting controls Pitch (tilt up | down) and Yaw (pan left | right). If you want to change these settings to control the ROLL of the camera, you can do this here.

2. The MIN ANGLE and MAX ANGLE is used to control the maximum allowed camera position when using the Joystick. The camera will automatically stop according to these angles. We recommend using -45 and +45 degrees. If you feel you want to control more or less camera angle through the Joystick, you can make the changes here.

3. Speed is how fast the camera movement is when the Joystick is used. A higher Value will cause the camera to move quickly when the Joystick is applied. A lower value will allow the camera to move slowly. If you want to change the speed of your camera movement when using the Joystick, you can make the changes here.

4. LPF is used to control the responsiveness of the Joystick controls.

HIGHER LPF VALUE will delay the camera movements after the Joystick is applied. The camera will also take longer to come to a complete stop after Joystick. It will basically ‘ramp up speed’ during the start of camera movement and ‘ramp down speed’ at the end of camera movement.

LOWER LPF VALUE will have immediate camera response. The camera will move immediately when the Joystick is applied, and will come to a sudden stop after Joystick application. This causes a ‘jerky motion’ which does not appear smooth, but is better for tracking very fast subjects.

5. INVERSE is used to change the direction of Joystick Controls. This is used because Joysticks can be mounted in different positions. If you move the Joystick Up and your Camera camera points down, you can change this with the Invert Option for Pitch (Tilt). After making this change, when you point your Joystick Up the Camera will point Up (instead of down).

TIP: If you apply Joystick UP and the camera pans Left or Right, and when you apply

Joystick Left the camera Tilts Up, then you can swap these controls under the first setting (see Arrow 1).

6. The RC Sub-Trim is used to calibrate the Joystick. This is an electro-mechanical control surface that over time may need calibration for it’s true Neutral Position. The most common problem is slow ‘drifting’ of camera position. When the Joystick is not calibrated properly, the gimbal believes that someone is applying Joystick commands and starts to move. To calibrate your Joystick, ensure that your Joystick is in it’s true neutral position. Make sure it’s not binding or stuck, and is centered as best possible. Then simply click on the Auto button and the values will automatically be entered. Or you can try to change these values manually to correct drift issues.

Save the Settings by clicking the WRITE Button after you’ve made the changes.

If your Gimbal is Beeping more than 15 times and continues non-stop, this could be a Low Battery Warning. If the beeping stops after about 13-14 beeps, this could be a Calibration Process (see here).

If the beeping does not stop, try to charge the battery for several hours and then try again.

If you feel you have left your battery charging long enough and are still having continuous beeping, you may either have a bad battery (not holding correct voltage) or possibly a bad Battery Charger.

Try another battery, or try another battery charger with your existing battery.

If your gimbal beeps several several times (approximately 13 times) whenever you restart the system, this could be a Calibration Mode. If it continues to beep non-stop, this most likely is a Low Battery Warning (see here).

When your Gimbal is going through a Calibration process it is important to have the entire gimbal level, hold the camera level, and also hold the gimbal frame square and centered. Once it is done calibrating, the gimbal should hold the camera position. If you allow the calibration to process while the gimbal or camera is not level, the calibration will be set to whatever position you allowed it to process.

We suggest disabling this feature and to only perform Calibration Manually when needed. To disable the Calibration process each time you restart, connect to the software and select the option 'Skip Calibration on Startup' under the Basic Tab.

Make sure to click on the Write Button to save your settings. Now each time you startup, the Gimbal will boot up immediately.

When connecting the Gimbal via USB to the software, sometimes you may find the motors do not operate when you power the entire system On. The problem may be a setting in the software that temporarily disables the Motors. This setting is used when you are working on the gimbal, and need to change settings without powering the system off or disconnecting.

To turn the motors back on, click on the Motors ON/OFF Button located at the lower left of the SimpleBGC Application Screen.

SimpleBGC Motors On OFF Button

If your system is powered on and connected to the Software, this button will toggle power to the Motors On or OFF.
