  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

DJI Ronin

You have to balance the camera BEFORE you power up the Ronin (or any other gimbal).
Properly balanced camera can be pointed in any direction and it will hold it without any movement.
I will post a balancing video soon...

Just read your post Peter, thanks for the tip.
How long does it take for you now to balance your set-up?

Less then 5 min...

I should have read the manual more carefully, it's mentioned page 14.
As my mom used to say: RTFM!
 
Curran - this is from memory, so I'm not 100% sure I'm right but to pair transmitter to ronin:

1. Power on Ronin
2. Find the pin-hole pairing button on the "spine" of the ronin near battery.
3. Using a paper clip or small hex wrench push the button - a light will come on.
4. Simply power on your ronin controller.
5. The ronin light will go off.

if this doesn't work go back to step 1. At step 4 - power on your controller with the left stick held all the way in the down position.
 
Just got mine from London Camera Exchange, they have a few in stock apparently

Well, I thinked there is an auto calibration like they mentionned on the website, didn't work ? I thinked now we were able to switch the lens quickly on set. So we need to do it manually ?

AUTO CONFIGURATION
After balancing the camera with a simple tap of the ATS (Auto Tune Stability) button, Ronin will be automatically tuned for your camera rig. The gimbal will intelligently adjust parameters based off the camera rigs weight and independently adjust each individual axis until an optimal setting is found.

You still must calibrate each time you change weight distribution, then use auto calibrate to fine tune. Its not that difficult and only takes a few minutes.

The auto calibrate function must start with a manual balancing first...so if you change lenses, you will need to adjust.
 
Thanks for your fast reply, because I meaned it was auto balancing too.

Will see this week, can't wait :)

Thanks !

Balancing your camera and calibrating / tuning your gimbal are three completely separate tasks. There is no gimbal in this world that auto balances your camera...

BALANCING CAMERA is a manual process where you align the camera's center of gravity with the stabilization axis of the gimbal (imagine lines extending from the centers of the three motors). The crucial step here is actually configuring the camera itself with all the accessories and figuring out where the CG (center of gravity) is. This alone can take several hours the first time you trying to configure your camera for work on gimbal. That is another step all together. The balancing process starts once you put your configured camera on the (powered OFF) gimbal. Everyone has their own preferred way to balance the camera and I will share mine shortly. It takes less then 5 min because the process is tool-less. I have tried this on another brand which required fastening of hex bolts with Alan keys for every adjustment and the process took on average 30-45 min. Every time you change lens and modify / adjust the accessories on the camera - you need to rebalance the CG. On the Ronin with little bit of practice this takes less then 5 min. This time saving quickly adds up as you work on a set where you need to change lenses / accessories several times during the day...

CALIBRATING GIMBAL is step where the IMU (inertial measurement unit) and all the other sensors are reset / calibrated for factory default and world axis. You only need to do this on the Ronin IF you notice that the gimbal drifts after it is powered ON. In the one month plus I have had mine I only needed to recalibrate the rig 2-3 times. This process is fully automatic and takes less then 1 min after pressing a single option "button" in the app...

TUNNING GIMBAL is process where the strength of the motors and their response characteristics are adjusted to match with the weight of your camera setup. This process is also fully automatic on the Ronin and takes also less then 1 min after you select the option from the app. It is this process that takes a lot longer on other gimbals that use the standard AlexMos boards - as there is no auto-tuning function. You need to setup each of the parameters manually, test it and then re-adjust, test agaian and repeat until you got it right. You don't have to do this on the Ronin at all, but you do have the manual controls if you wish to for what ever reason modify these settings.
This step is also required every time you change lens or modify the camera configuration that results in change of the overal weight of the setup. Again - on the Ronin this is automatic step that takes less then 1 min...

What do I have to do to get the controller to sync with the Ronin? Is there a special sequence to get them to connect?

Curran - RTFM... ;o)
Page 28 of the Ronin User Manual...
In any case your remote should have come already paired with your Ronin, but if you want to use your own compatible controller, or the one that came with the Ronin is for what ever reason not paired with it - just follow the steps in the manual...:

peter, I know that there's not a lot of Ronin footage to compare it to Movi, but from what I've watched the Ronin reflects the footsteps of the operator more than the Movi does. At least this is what I've seen, Have you used a Movi or similar gimbal and did you notice something like this?

Thanks. I didn't realize there was a manual available online. My controller didn't come paired. Everything else seems to be working ok.

No worries. This (having manuals online in PDF format) seems to be the best solution in this day and age. RED is doing exactly the same thing.
It saves the environment by not needing to print stuff that is out of date before the ink has had a chance to dry... ;o)
You always have the latest manual available for download to your device.
I keep all user manuals for all my gear neatly organised inside iBooks on my iPad and regularly replace the old versions with the latest ones.
When you open any PDF online with your i-device - you can just tap on it and in the top right corner there will be an option "open in iBooks" - this copies the PDF physically to the device, so you can access it via iBooks regardless of you being connected to the internet.
Inside iBooks you can create your own "folders" and organize all the PDF's...

Cheers

I am going to vent on here for a couple of seconds so please forgive me.

DJI are showing an absolute disregard for UK buyers of the Ronin. From what I hear from the distributors, they refuse to give up to date information, and have to be chased around for days before even short emails are replied. I have just heard this morning that they sent only 5 units to their major U.K supplier. From the info on here, AMP received a significant consignment a few days/a weeks ago.

Let me say here - we do not pay less for the product than our American cousins. To be treated like second class citizens (as an afterthought) is really rude. i have been reading this thread for sometime about DJI's customer service, and they have tried to argue they do a decent job. But even their distributor in the UK is frustrated with them.

DJI - I don't know if anyone from the company is reading this - but you guys need to do better. It's one thing to create a product, its quite another to develop a good reputation and deliver good customer service.

Nosa, if you have followed the GROUP BUY thread - it was initiated by Zeb and AMP. Part of the deal was that AMP would receive the first batch of units. This has nothing to do with us Europeans (yes - I am European too, just based in Japan) or any other continent's people being "second class" citizens.
DJI has also stated that even before the price drop they had 2000+ pre-orders. With few weeks between the price drop and now - I expect those numbers are significantly higher.
It will be a while before Ronins are readily available in stock at the resellers...

It has been stated that you cannot run the camera off of the ptap. It's low, like 6v or something, which the epic needs at least 12. Maybe this could be changed with firmware.
Click to expand...

First of - the voltage in the P-taps is 12.8V - which is enough to power the camera. This is not the reason why we can't do it.
The reason is the power draw (amps) - which is also related to the thickness of the cables running the power.
The current cable is designed to cary data information and only enough power that the cable can safely provide without overheating / melting.
THIS is why you can't run the camera from the Ronin's battery.
Just look at all the various power cables for the RED - how thick they are. Such a thick cable will drastically affect the balance of the gimbal and prevent it from operating the way is meant to.
If you wan to power the camera from the Ronin battery - this would require product redesign with so called "slip-rings" instead of direct power cable...

So - in conclusion - Ronin as it is will not allow to power the RED directly from its (Ronin's) battery.

Various people have their own preferences. I find this approach safer as the camera can run out of its power and the gimbal will still stabilise it.
If you were in remote scenario (let say using the Ronin on helicopter, car, boat, etc...) and the camera was powered from the Ronin and drain the power to shut down - the gimbal will stop stabilising and the camera could start spinning violently depending on wind, motion of the rig at that time and other factors (how well it was balanced), etc...
Even if you were hand-holding the rig and the Ronin would suddenly power down - it won't be pretty for the very same reason...

:sifone: Peter
 
Why couldn't the power cable run thru the arms and under the camera just like its supplied to the motors?
Then we could have one larger battery capable of powering everything. Having multiple batteries to deal with means more weight than necessary.

Regarding losing power mid flight...well that can happen regardless of how many batteries you have and if you don't know the consequences, then you shouldn't be operating.
