My FeiyuTech Mini3d Problem
0Hey bros hope you are all doing well. So I finally got around to buying the mini3d for the p 1.1.1 that i got on meh and made myself some lovely adapter cables and some new holes for the huge multicable. After first power up it wouldn't do anything but point down everytime I powered it up. So I updated the firmware in hopes that would fix it. After a failed update success it doesn't face down anymore. But for some reason I don't have function from my F1 F2 slots. I activated it in the Naza and deactivated the IOC channel so I can have Tilt on the back lever and the IOC switch to be my mode setting switch? (hopefully possible) But I have no movement from the gimbal other then it following me moving the Phantom around. Perhaps there is no signal coming out of the gimbal or through the cable? Could I check for levels in the signal lines? I am happy it at least tracks heading.... hoping to figure this problem out.

@sp3ar, it sounds like you're in Axis Lock mode?
Unfortunately FYT doesn't document the functions very well, so we have no idea if the mode line should be high, center or low for "normal" mode, but it sounds like whichever channel you're plugged into is set to whichever value is Axis Lock.
At least I'm assuming from your description you're in Axis Lock mode? Maybe posting a 10 second video showing the gimbal in action would be useful.
ugh so I had to enable disable the gimbal switch in the naza software over and over about 10 times before it actually started responding! it moves with the p1 gimbal pitch lever. now if only I could get the IOC switch to work the gimbal modes then I would be golden but I am happy it stopped giving me the cold shoulder
weird so I unplugged it from the software and it still was working so I unplugged the battery then plugged it back in and now its not responding.... what a weird issue
so I plugged the gimbal modes connector to f1 and I believe thats what is causing the unresponsiveness..... i unplugged it and now I have pitch control again. I guess it's stuck in the mode it's in which follows phantom movements in pitch and roll and I can control pitch manually as well.....
@sp3ar It seems F1 is sending a fixed PWM value to the gimbal. This explains why it goes into a lock mode when F1 is connected. You need a channel that will give the gimbal 3 different PWM values. I'm unsure exactly what values the mini3D is looking for, but a guess would be <1200, 1201-1799, >1800 give or take. Each PWM value range sets the gimbal into one of it's three modes.
In my case, I connected the mini3D mode line to a variable channel on my Devo RX, and control it with one of the dials on the Devo F12e TX. In your case, you're going to have to do a bit of searching to find out how to get 3 distinct PWM values from the DJI RX.
@ruouttaurmind Feiyu also didn't give me any information about it only stating in their words "the gimbal just need control via RC,can't control via NAZA" what I did do a year ago is buy myself a secondary RC with a RX so perhaps I could use that in the phantom if I really wanted? Does the mini 3d remember what mode it was in? or does it reset everytime you turn it on? I wouldn't mind attaching another RC to the gimbal to change modes before I close it up for flying
@sp3ar That's essentially the same thing they told me when I contacted them. I asked them for the PWM values for each of the modes. "mini3d just need control from RC channel and select modes." Helpful yes? No.
Mine resets itself to what I guess I'd call "standard" mode every time it powers on if I don't have the mode control connected. I haven't yet fussed with the setup software to see if I can change the default modes, etc. I'm still running the second generation firmware because everything seems to work properly and I'm afraid of effing it up with the new firmware.
The primary reason I got the mini3D was the yaw control (ya, I know, just a useless feature) and also I was excited by the video passthru. The ability to connect one wire from the gimbal to my GoPro and have it get power as well as pass back video. Unfortunately I haven't been successful in getting video passthru to work. Powering the camera works perfectly. Getting video back through the gimbal... not so much. So I'm still working with that.
Just curious, does yours have the aluminum motor mount/covers, or the original plastic ones?
@sp3ar BTW, it occurs to me... you could control your mode selection with a simple servo tester if you're looking for a cheap, lightweight solution. Of course you'd have to set your mode from the ground, but you'd have the ability to just twist the dial on the servo tester from low-medium-high to select the three modes. Something like this either mounted inside the fuselage (with the knob sticking out) or just velcro/sticky-taped to the bottom. They can be had from China for $3 or $4.
@ruouttaurmind i got the mini 3d because of its weight and 3 stabilizing motors, I don't believe for one moment a 2 axis gimbal will out perform a 3 axis the world is not flat! and i don't believe rubber balls of any stature can respond to motion like motors would. I got mine on ebay for around 120 dollars give or take. So I am not feeling bad about the buy. so does the servo tester need power on the red black lines? probably a rhetorical question.
I honestly can't tell they could be plastic
@sp3ar Yup, the servo tester requires power. Usually 5-7vdc, but there are some out there that can take up to 12vdc. Of course those will be more 'spensive and heavier.
Here's one from Banggood for $2.25 w/free shipping. Requires 5vdc.
From the pic above, Imma say yours has the aluminum mount/covers. MUCH better than the original plastic ones. The plastic had an awesome sleek ninja-like appearance, but mine broke on the first flight with a very light bounced landing. After almost a month of back-n-forth FYT finally agreed to send me the aluminum replacements, but charged me $30+ in shipping. I pressured them into sending me a spare main cable and spare GoPro charge/video cable because the shipping was so steep.
Welp after getting my Tx setup connected I am finding that my video passthru is not working..... it is pushing power to the gopro but no video into my Tx so I see nothing on my Rx monitor, I had another video cable already for another setup I have yet to use and I can get video into my Rx to monitor so I didn't know if perhaps one of the 2 cables is the culprit or the gimbal internal connections. also trying to control pitch with the phantom 1.1.1 gimbal lever is a whole task in itself since to stop it from going in a direction i have to center it which is difficult with no center notch to rest in while trying to fly haha is this something I could change in the naza gimbal controls?
@sp3ar I was also unsuccessful in getting video pass-thru from the gimbal.
The cable that was included with the mini3D didn't work (and it was supposed to be video pass-thru only; no power).
I bought another cable on eBay. It was supposed to be a video pass-thru AND power cable. Power worked fine. Video pass-thru didn't work.
I contacted FYT directly and cajoled them into sending me another cable. It was also supposed to be video pass-thru and power. Again, no video, just power.
After that, I gave up.
