Setting-up and balancing the Ronin or Ronin-M

This is a quick guide to setting up the Ronin and getting the balance dialled in. It is important to have a neutral balance as it will allow the battery to last longer and protect the motors from overheating. These are the steps as laid out by DJI for getting the balance dialled as well as some trouble shooting help. Below you can also find videos created by DJI which cover the setup and balancing of the rig. You will also find links where you can download the product user manuals.

Getting ready

It is recommended that you start by ensuring the Ronin batteries are full charged. You will also need the DJI Assistant app installed on a smart phone. The requirements are iOS version 7.0 or above, and Android system version 4.3 or above with Bluetooth 4.0 support. Create your own DJI profile and login details for the app. You will need the Ronin’s password to connect it to the app.

Step 1

Setup the camera and attach the camera mounting plate.

 

Setup the camera you intend to mount to the Ronin. Make sure you put in the battery and recording media and any accessories like filters and the lens you going to shoot with, also remember to remove the lens cap. Once you start adjusting the balance you do not want to make any changes as it will throw the balance off and you will need to start again. Then attach the camera mounting plate to the bottom of the camera.

Step 2

Front to back tilt axis (Move camera forwards or backwards)

 

With the Ronin resting on its tuning support stand, insert the camera mounting plate into the wedge plate cradle on the Ronin gimbal. Try find it’s centre point so it does not fall forward or backwards getting an approximate rough balance where it holds level on the rig. At step 5 you will repeat this step after having addressed the other axis.

To set the “front to back tilt axis” hold the camera so it is level, then let go. If it falls forward, slide the camera backwards. If it falls backwards, slide the camera forwards. If it stays level when you let go, you have achieved balance.

Step 3

 Vertical tilt axis (Move camera up or down)

Move the camera up or down by unlocking the latches on the vertical rail. Use the etched markings on the vertical rail to ensure the latches on either side are at the same height after each height adjustment.

To check the “vertical tilt axis”, tilt the camera backwards so the lens points to the sky, carefully let go and note which way the camera falls. If it rotates forwards it means the setup is bottom heavy and the camera needs to be moved upwards. If it rotates backwards it means the setup is top heavy and the camera needs to be moved downwards. When you let it go and it stays in position, you have achieved balance.

 

Step 4

Roll axis (Move camera left or right)

Turn the two latches which allow the camera to slide from side to side. Move the camera left or right until the camera holds a horizontally level position.

Hold the camera so it is horizontally level, when you let go it should hold that position. If it drops to the left, move the camera to the right. If it drops to the right, move the camera to the left.

Step 5

Front to back tilt axis (Move camera forward or back)

 

This is a repeat of step 2. You are going to rebalance the cameras forward or backward position based on any changes that might have occurred as a result of the shifting of the centre mass from the other axis being balanced.

 
 

Step 6

Pan axis (Move Ronin pan axis knuckle forwards or backwards)

 

This ensures the entire assembly under the hand rail is not too front heavy or back heavy. This is done by loosening the latches and sliding the lower assembly along the arm. Depending on the model you are using this may also have a screw which allows for fine adjustments.

Tilt the whole rig by the handles, backwards or forwards so one side is higher than the other (rig battery or camera). If you rotate the rig so the camera is at a higher position and it rolls down to a lower position the rig is front heavy and needs to be moved backwards. If you rotate the rig the opposite way so the battery is at a higher position and it rolls down to a lower position the rig is back heavy and needs to be moved forwards.

Step 7

Turn on the Ronin.

 

Press and hold the battery on button for 1 second for the unit to turn on. When the Ronin turns on it will orientate itself to face forward and hold level.

 
 

Step 8

Connect the Ronin to the DJI Assistant app

 

Your smart phone will need the Bluetooth turned on. Start the app and it will scan for devices. If it is the first time connecting to that unit it will need the password. Cam-A-Lot Rentals has a sticker on the tuning stand with the password. If you reset the Ronin-M there is no default password. On the Ronin, the default password is DJI123 or 12345.

Within the app, select “motor” and then “Auto tune stability”. This will try find the optimal settings for the weight of the camera attached. If you have any noise or vibration, lower the stiffness settings.

Step 9

Test the Ronin

 

Within the apps “motor” page open you will see the power being consumed by each axis. This will let you know how well balanced the rig is. You want those values as low as possible while the camera is on the tuning stand. If you have readings of 5 or over in the power column, you should retrace the steps to get a better balance.

Trouble shooting

The Ronin rigs are pretty reliable, but there are a few events which have cropped up during shoots. All are easily rectified if you know where to start. These are the the top queries we have come up against, if you have other issues refer to the user manual.

Gimbal is vibrating and making a noise: 1 Tighten all knobs, screws, locks and latches.
2 within the app drop the “stiffness” value to a lower value (within the motor menu)
 Motors shut off:  Rebalance the camera, power cycle the gimbal.
 Off centre or drifting: On the app use the “Calibrate system” and “Calibrate centre” functions.
