Cheap setup, will all this be okay?
I purchased a different camera mount from Aerial pixels. Much better and adjustable etc.

Running IMU through slip ring
Have had no problems with mine so far but I don't believe the quality is that good so it doesn't surprise me that some people are having issues, I am not aware of a quality manufacturer of these.

I have the Canon 5D MkII with 24-70 lens, heavy setup, all working well with stock motors that come with the Legacy. I only have one issue which isn't affecting performance but on the roll motor as it holds a lot of weight the motor bearing mov…

Headtracker gain too high
Which indicator are you looking at? The arrow or the dot? The arrow is the actual indication and the red dot is the higher resolution indicator to show finer movements.

I have ordered 3 Alexmos boards from RCTimer with no problems at all, the latest 32bit is doing well, I got it with the aluminium enclosure, very nice. Postage was always reliable and price is good. I have the combo Legacy Gimbal and board. I have b…

PID problem on my 3axis steadi with 32bit alexmos...
Ok, I've just uploaded new software and carried out autotuning, it has radically changed my PID's, very high numbers, Roll is 205 0.12 103, Pitch is 202 0.22 86, Yaw is 205 0.08 167!!! Never seen such high numbers. My camera and lens are h…

I had problems with high freq oscillation that I couldn't seem to tune out, once I had selected high sens it went away, I know it could indicate something else isn't set up correctly. I will load the new software and retune. I'm juggl…

No power to yaw when gui is connected
Have you tried connecting the yaw output to one of the other axis to narrow down if the problem is external to the board? Have you enabled your 3rd axis correctly?

I am running the same motors with a 5D MkII. No problems. I noticed your lens seems to be in auto, it must be in manual otherwise it will go out of balance very quickly. See below from a previous post of mine. " RC Timer legacy hand held gimba…

Running IMU through slip ring
Are you using ferrite rings at both ends of the IMU cable? Very important.

Mos 32bit 3axis 2.41 b5 - All stable until RC input - then pitch oscillates
Just had a quick read of your problem, the 180 degree change sounds like the axis is 'looking' for the nearest pole on the motor and then moving to it, not sure why it would not stay aligned in the first place though, it should not need to…

Is anyone ACTUALY using this 32 bit controler on a regular basis with any success
Working ok for me on a handheld, still got a little wobble to tune out but used it on a shoot last weekend with ok results.

yaw will not return to home from one side in follow mode 8bit
Problem sounds more serious. You need to figure out the power problem first, there should be no difference when connected.

yaw will not return to home from one side in follow mode 8bit
Yes, weird. Do you have any deadband set? Does the red dot return to the top (north) on the gyro and does the blue arrow follow it, or does the red dot stop short of the top (North)?

Sounds like a gyro calibration may be needed or perhaps your imu is moving slightly during the initial yaw? What happens when you carry out the Acc, does it stay aligned or drift?

Slow drift of frame IMU after fast movement
I'm not getting that drift so I don't think it's normal. Try to reduce your gyro trust, mine is at 70.

Looking forward to this, bluetooth module is on the way. Would be good to use my mac in the field.

Mac Bluetooth issue
I wasn't aware that the GUI or Firmware was available or compatible for Mac. I don't use my mac for the alexmos stuff, even in Parallels, there are limitations when emulating windows on a mac, several other posts on here that describe prob…

It's not compatible with a mac as far as I know.

High pitch noise and uncontrollable shaking in gimbal
Hi Thor, According to the link for that gimbal it comes with a 32 bit controller. What GUI software are you using? Post a pic of the control board and maybe we can figure out which one it is.

High pitch noise and uncontrollable shaking in gimbal
Thor, If you read the manual very carefully it will give you some very good tips. Basically if your rig is balanced very well you can start to tune. Reduce your power on the PID's down very low and also the Power to motors, this stops the rig …

GoPro Gimbal - Power Question
Try just connecting the board ground to the usb ground on your computer (not +'ve), this should prove your suspicion, which I agree with, it could be a grounding problem, although it should be a simple + and -'ve from the battery which wou…

Perfectly level until yaw
I'm wondering if this problem is related to some sort of gyroscopic precession. From my helicopter studies I recall something like this happening but would have to research more.

You have the 32bit board from what I can tell. Have you downloaded the correct GUI and firmware? Check the 32bit downloads. Disconnect everything accept for the USB and see if it will connect.

Hand held Legacy gimbal Canon 5D MkII Lens selection
Still undecided about which lens to get, I understand the focus issue. Very reluctant to use Autofocus, I don't like it for video. Will have to look at remote focus control systems. Seems like anything up to 30mm f2.8 should be ok, but very exp…

Test using a PC. It could be the mac is 'emulating' the serial control and causing problems.

Pitch channel causing problems
When it's powered off tilt the whole gimbal left and right, if the yaw is balanced the camera (lower part of the gimbal) will not move. If you tilt/lean to the left and the camera moves (rotates) to the left then you need to adjust the arm belo…
