Hello, it's a very nice video to show how PID setting works. Nevertheless I have a couple of things to point to how you've mounted your gimbal. The motor with the hollow shaft if to be used in the YAW motor, so you can pass the yaw motor cable by itself but also if applies, cables from a receiver and also from a battery from above in a multicopter going to the alexmos controller. This way the camera can rotate as many times you need without any cables to get mangled. I also have to say, and most probably you know that, that the pitch motor is in the "wrong" side. The advantage of this position is that you can access perfectly the AV and HDMI ports, which otherwise would be complicated if not impossible to use it. The downside of having the pitch motor in the "wrong" side in this gimbal (designed for Sony NEX/alpha cameras) is having the lens misaligned with the roll motor. Instead of having a smooth perfect roll, you'll have the lens going up and down when it rolls, and that's why the final test is so shaky, no matter how well set your pid's were. These are my 50 cents, I hope it helps someone. Anyways, this was most probably the best pid setting video of an alexmos controller.
Hi mate, thanks a lot. You are absolutely right. I needed to change the Yaw motor as the original from DYS was to weak, normally you will take one with center hole to get the cables trough. On the pitch motor, you are right as well but left it quick and dirty as it was just for the demo... thanks for the comment and for the kind words on the vid.
Thank you very much for a very good explanation on how to set up the Alexamos/Basecam Controller. I am having problems with the Gimbal that I am puting together with the Alexamos 32 bit Controller. After calibrating, and hiting the auto for the Gimbal to configure itself, after a while it start going around in circles, After that normally I turn it off and recalibrate it but the same thing start happening again. Do you think you know what I am doing wrong? Thank you
Excellent video. I am running a single setup. I had done a rx off the gimble for the camera shutter, up down and then zoom on the third channel. I had been told you can use virtual channels to do the same thing without having a full RX on the bottom and instead using the 3 servo leads would plug into the basecam. I am not seeing this. Was I told wrong or do you know if this is possible? Thanks
Excellent tutorial. I have a 8 Bit Alexmos gimbal controller and the gimbal as configured by the manufacturer performs very well except for a small adjustment I wish to make. The horizon in my videos is very slightly tilted to the right or not perfectly level. So I assume I should recalibrate the IMU. and leave all the other settings alone. What would you suggest be the easiest way to do that in the GUI? I plan to place a small bubble level on the top of the camera as an aid for leveling the camera for calibration. Many Thanks!
Hey Mark, you've probably figured it out by now... but level the base of your gimbal, with the camera mounted, and click the calibrate ACC button. Personally I plugged the gimbal into the PC, plugged a battery into the gimbal, then clicked calibrate ACC and quickly leveled it out before the calibration finished (you really need to be quick). worked like a charm.
I have watched your video "How to: Alexmos/Basecam Controller - Make it work perfectly". I have the same controller. One thing I cant figure out is what pins on the alexmos controller is used to go to the rx? Have a video or a wiring diagram? Thanks and great video!
Hello Locoracers, This is THE BEST video out there on gimbal tuning. It is understandable and you understand the settings very well. I do have a general question: Many of these gimbals are for large cameras with some weight. But I have a FPV camera that is very small and light. I want to use it on my multirotor, but my gimbal is advertised for the GoPro camera. The GoPro is much heavier than this little camera I have, so I need to know if it is possible to balance the controller and gimbal with only a small (4 gram) camera? My gimbal is 2 axis, so the pitch motor is heavier than the camera, and mechanically it would be out of balance without a camera. So, is this possible to balance with no camera or even a very light camera on the pitch axis?
I would like to know about the high pitched squeal as well. Can that be removed in any way? It would make using a gimbal for video work requiring capturing vocals impossible if not.
mrmitee You can adjust the frequency of the steering of the motors. I have left it on default but you can set it to high and the background noise disappears.
Of course your video is much appreciated and quite thorough, but is there not an autotune process that you may invoke with the Basecam GUI? Also while I am shopping around for possiblities, is the high pitched audio oscillation coming from the motors or the controller? I have a 2D that produces no sound. Not that it would be noticeable over the sounds of a multirotor, but in the case of a DSLR for handheld "Steadicam" use, this noise would corrupt an otherwise usable sound track no?
Chris Leech Hi Chris, you can choose in a menu point the gimbal to be silent mode. Also in the video there it the 8bit controller visible and not the 32 bit in an earlier version. So no auto tune. I have experimented with Auto tune on the latest 32 bit boards and its not yet working for me but also not working for lots of others.
I have the same gimbal and updated my firmware lost all settings and have to start from scratch - Would it possible to get screen shots of your setup??
Hello, great Video best on the subject but I have a 2 part question, the sensor you removed to calibrate glue to the back of the camera holding bracket and can not be removed, can I still calibrate by pointing it same as you do and also what reference axis top and right would that be, I'm new to gimbal tuning and any help would be greatly appreciated. Thanks
joe comonte Hi Joe, I don't fully get the question but I think its feasible that you glue the sensor to the back of the cam and do the calibration. With the newest Firmware and 32bit you do have some support in the GUI for the calibration so you don't need to remove sensors any more.
Locoracers thanks for your answer, I have an older 3 axis 8 bit gimbal and after the calibration per your video i keep getting pitch and roll inverted (right is left and up is down etc) what am I doing wrong?
joe comonte You have set the axis wrongly in the GUI. If you place yourself and your laptop with the GUI behind the Gimbal and move tilt and roll the instruments must move accordingly otherwise the axis (-z, z, -x,...) is wrongly set. Just try out every combination until the instruments move accordingly.
I had problems connecting the board to the computer, I tried it on three computers, and it finally conected to the third. Question: the gimble points the camera to the ground instead of forward, how do I fix this? ( the joystick will move the gimble side to side, but not up and down.) any help would be hot, Bob
I liker your video but I have a question because I have 8-bit controller and want to connect the joystick , but can not find any place a connexion diagram. You know how to connect the joystick to the motherboard? I hope you can help me, thanks!

How did you activate the yaw motor. does not appear on video
Hello, great video and very informative. I have tried setting up a goodluckbuy 2 axis gimbal but the roll motor is not working correctly. gimbal is okay until it tilts sideways, then roll axis drops to 45 degrees from the horizontal. I can push it back to the horizontal by hand, but again, any motion in the roll makes it drop to 45 degrees again. Any ideas ??
Hi Dennis, I would suspect that either the motor is too weak, the power settings are not optimal or the balance is not correct. I see on a lots of Gimbals that they include very weak motors, especially if the Gimbal is a cheaper one.
hi Darrel Is it this kind of gimbal? www.hobbygaga.com/fr-brushless-nacelle-cam%C3%A9ra-w-moteurs-contr%C3%B4leur-pour-gopro3-gopro2-a%C3%A9rien-p265248.htm Because I have the same problem of you. It seems that the motor isn't strong enough
YAW works perfect for me when the gimbal is horizontal, but whenever its not perfectly level it slides a lot , does that mean the motor is too weak to compensate for the gravity?
Hmm..seems like this is another type of issue. Suddenly all the sensors just go bonkers and start to spin in all type of directions. Then i restart the board and everything is back to normal for a while. Not sure what triggers it, although i havnt added ferrite cores yet, could that be the reason?
Set the PWM frequency to HIGH to eliminate the whining. And don't upgrade the firmware unless you have a genuine Alexmos controller not a fake chinese one because it will brick it. Anyway good tutorial, thanks for that!
I took my Phantom out for a test flight with great expectations. But as soon as it took to the air I had oscillation in the pitch of the gimbal. When I land and just give the gimbal a nudge it settles down again. But as soon as I take flight the oscillation returns. The funny thing is I can move the Phantom in my hand aggressively and the gimbal works awesome. But as soon as I take to the air it oscillates again. I have video if that would help any????
Hey mate, I understand that if you hold the Gimbal in the hand you have no oscillations, correct? Can you confirm that its the Gimbal that oscillates and not the vibrations of the Phantom are transferred to the picture?
Hi i bought the gimbal that cames with 8bits 2.40 b7 firmware. It doesnt stabilize and when powered it start shaking . see the video th-cam.com/video/hwkxBy5Qz-M/w-d-xo.html What i have to do ? any tip ?
The high pitch from the motors makes it impossible to watch with audio. That's what's wrong with most of these low cost gimbals. They mostly run around 16KHz PWM. They should up it to 30 KHz or at least >20KHz so those of us that are not hard of hearing in higher frequencies, don't suffer. Having said that, if these are mounted on a multicopter, then not an issue. If you try to make a handheld version, then you are faced with the high pitch noise dilemma. These gimbals are therefore only suited for applications outdoors or in noisy enough environments where the noise from the motors are not as pronounced.
I need some help. My gimbal jitters when I roll to the right. I might have inadvertently changed a setting. I'm really not sure at this point but here is a video showing what's happening. th-cam.com/video/jCYH5X-8JPs/w-d-xo.html
Seems that you are using a very old version of SW. I am not familiar with 2.2. Anyway, the root case might be different things: a) IMU not calibrated, ACC not calibrated, pitch motor on the wrong side, low gains...
Locoracers It did work earlier. Is it possible the motor has a bad pole? i just noticed i move it past the point where it jitters it works fine. It is just in one specific area of the motor that it gets stuck and jitters. above and below that point it seems to work.
Everything you'd explain is just as simple waste. You want to give us experience but you made one major fault during calibration: you patched the IMU with soldering pins on a plane surface. And further at 6th axis you didn't the cube on tables edge and made measuring with the IMU itself standing headover hold by hand... That means: You try to present yourself as "expert" but there's none

Thanks for the video, I've been pulling my hair out trying to tune my gimbal. Now I have a idea how to tune it. Thank you.
Very nice detailed demonstration.
Great video, helped me a lot in understanding how the PID stuff works and how you set it! Thanks a lot.
+ebastler Thanks.
Glad you liked it!
Awesome! Wish I had seen this 2 months ago before I almost pulled my hair out ha. Time to revise my settings with your video. Thanks!
Excellent Video! Very well explained. Thanks a lot
Chris
Tanks!
Nice video! Can you explain the difference between the 32bit and 8bit controller and what are the differences in use?
Thank you very much for this video.

Because I have the same problem of you. It seems that the motor isn't strong enough
@Locoracers, when trying to follow the step where I plug in the battery, the gimbal goes crazy! Any ideas?
what GUI software were you using?
do you know how to program for controll of yaw axis ?
I have 2 sensors from my board, any idea how to calibrate two?
did you have any lights on your IMU sensor light up when you connected it to your board?
I don't have it in front of me yet but I don't think that the IMU has any light. Its really only the sensor on the plate.
what motors are those?
YAW works perfect for me when the gimbal is horizontal, but whenever its not perfectly level it slides a lot , does that mean the motor is too weak to compensate for the gravity?
Sephiroth S Could be or the mechanical center of balance not correctly adjusted
Hmm..seems like this is another type of issue. Suddenly all the sensors just go bonkers and start to spin in all type of directions. Then i restart the board and everything is back to normal for a while. Not sure what triggers it, although i havnt added ferrite cores yet, could that be the reason?
here is a question that none of the videos addresses . for the beginner . What Battery is used for the gimbals ( you have 4802 motors on that one)
3S for this one.
Thank you for the response
In the compass , i have the red dot spinning constantly around the compass, , one lap in ~2 seconds. any idea what it is??
Sephiroth S Probably just calibrating the sensors in the 6 step manner
Hi, can you fix my pilotfly H1, with this problem, "Unable to connect to bootloader"
I'm confused please answer. Do you need an esc between this an the motor?
+JBpiification No, the power is controlled by the IC's on the Alexmos board.
Habe ein Gimbal das ich nicht Kalibriert kriege. Könntest du uns helfen?
which board is this. im not sure what board to get
8bit Alexmos. Make sure you buy Basecam authorized ones.
Great tutorial, however I hate out of focus videos lol
Do you need to PAY extra for the firmware?? I can only find the trial... i hope this is not the case...
Costa Concordia No you don't. Can be downloaded FOC from the Alexmos website.
Locoracers Thanks!
Set the PWM frequency to HIGH to eliminate the whining.
And don't upgrade the firmware unless you have a genuine Alexmos controller not a fake chinese one because it will brick it.
Anyway good tutorial, thanks for that!
i have a chinese board and i've upgraded the firmware how can i get the old one ?
when i plug the power into the gimbal it displays a red light and won't innitalise
I took my Phantom out for a test flight with great expectations. But as soon as it took to the air I had oscillation in the pitch of the gimbal. When I land and just give the gimbal a nudge it settles down again. But as soon as I take flight the oscillation returns. The funny thing is I can move the Phantom in my hand aggressively and the gimbal works awesome. But as soon as I take to the air it oscillates again. I have video if that would help any????
Hey mate, I understand that if you hold the Gimbal in the hand you have no oscillations, correct? Can you confirm that its the Gimbal that oscillates and not the vibrations of the Phantom are transferred to the picture?
I'm positive that it is just the gimbal. And pitch only. the camera actually oscillates about 3-4 mm. but if I touch with my finger it stops again.
Where is the first part?

Can absolutely be true. Check also for broken point in the cable or at the soldering point.
