Micro Gimbal for GH4, BMPCC, A7s - $699 USD

After watching your video, no point in my uploading one (I did make one to send filmpower), because it looks almost exactly like yours. Mine is not consistent though- sometimes the camera pitches back slowly, and sometimes all axis go crazy. I have to turn off the motors when it is sitting on a table on the handle like yours, as it would fall over. So far I have not gotten a sensor not connected message.
 
did you calibrate the sensor press 4 times then press 5 times? after clicking auto on the motor configurations?
 
Sounds like both you guys have fallen foul of the wire to the IMU being twisting/pinched and damaged. This is exactly the problem I experienced if you can remember back that many pages? You will surely remember the Filmpower staff member posting photos of the wires on my returned model accompanied by outrageous claims that I twisted it on purpose...

Starting to look like it's a more common issue than Filmpower were willing to admit at the time.

Sorry guys - but my testimony was here for you both to read.

For what it's worth, I bought my third from the UK distributor and have been treating it with more care than a newborn baby. No problems thus far. Here's hoping!
 
I just opened mine to see what's inside. The good news is that all the connections are solidly soldered in. The bad news is that by permanently soldering the connections, and coating them with rubber/plastic, it's both difficult to see if a connection has come lose, or become shorted, and very difficult if you want to replace a wire. Most cards like this have connectors, so if a wire goes bad, as it did on my friends gimbal, I can just plug in a new wire (or splice together a new connector).

The Nebula was not put together to be easily serviced. Though, if done well, this is a good decision if you don't want connectors shaking loose, etc.

The other worrying thing is the card is precariously close to the handle and the daughter cards are jammed in there. So my advice about getting an electronics expert to help you must be amended to...it would be asking a lot of them because they would have to de-solder the cards apart--not trivial.

My IMU cable is obviously flattened, from the card door, where it re-enters the card chamber.

In short, if the Nebula was put together with care, it should be rock solid. If it is NOT, then it will be both difficult to trouble-shoot and/or repair.

You wouldn't want a Nebula put together by someone nursing a hang-over at the factory. Probably not a joke you can laugh at.

Yes, but after the unit was returned to me the 4 and 5 press of the button were not set for calibration, they were turned off. When I try to set them for calibration, it doesn't work. I can't really change any parameters, even though I am connected. All I can do so far is turn off the motors.

when you say "My IMU cable is obviously flattened, from the card door, where it re-enters the card chamber." is there a diagram for this? sorry max you really know you stuff don't quite understand the lingo.

thats very strange...if you loaded someones existing settings the option would be available you think?

It looks like the big daughter card is connected through a connector, but the connector is actually soldered in. You can't pull it out. As you can see, that big cable, that comes from the IMU, is flattened. The smaller card is also soldered into wires. You can also see how the daughter card is soldered in crooked. Again, not necessarily bad, but not confidence inspiring either.
 
Guys - I've been through all this. I looked to see if I could find any poor connection but as has been said, the connections are all covered in melted plastic. It's impossible to see. It was posted on here, but I'll show you the photos that Filmpower supposedly took of my wires of my return model once they opened up the plastic sleeve. I have no idea how this damage could have been done as it would surely have required a crazy amount of twisting (which as I've stated I was being careful not to do).

I would assume that you have damaged wirwe too as the connections (I think) are all fairly solid.

I'm afraid you will have to return your products. Hopefully you will face a response other than accusing you of twisting on purpose to make the company look bad! lol. You couldn't make it up!


Mainstreetprod - if you sent yours back and got a faulty one sent back to you, then that puts you in a very similar situation to mine. Be prepared to have them be very suspicious of you. They refused to send me a third replacement. I wonder will they accuse you of working for DJI along with me!

They supposedly repaired mine rather than replacing it. It did halfway work for an hour or so, but that was it. My cable is flattened exactly like Maxotics in the same place.

Does anyone have any tips on tuning the yaw motor? I've balanced the sled as well as possible (given that there are only 3 fore/aft positions), but I'm still experiencing jitter at the when the yaw motor starts and stops a movement.

As you can see from the realtime data, the beginning and ending of the yaw movements are quite chaotic.

Any tips or suggestions would be appreciated.
 
maybe do an AUTO test on the INVERT in the software - maybe the polarity is wrong on one of them?
The guy in the below link talked about it. I wish I knew exactly where he discussed it's a long video. More towards the end if memory serves.
Anyway - mine was also being erratic after balancing it - and playing with the PID's.
I ran the AUTO test and it was back to normal

Removing the sensor to get a more accurate calibration?

Removing the sensor to get a more accurate calibration?

Hey Guys,

take a look at this video, you can skip to 2:40 to see what I'm referring to.

this guy removes the sensor from the gimbal and then does a 6 axis calibration using a box.

I checked the Nebula, and I do see screws on the sensor, but I think you wouldn't have enough slack on the cable to do the box thing.

any thoughts?

 
I've had dealings with them - i wouldn't worry too much.
They are a little slow in getting back to folks.
I'm sure you won't have a problem.
 
Yes, I've finally got a reply from them to return the unit. Hopefully, things get better from here on.
 
My bank sends me email alerts where a couple of purchases I made today show up then a deposit I made last week, in other words, out of order. Banks post transactions at different times, based on banking-arcana. I know you're upset mainstreetprod, but even your chargback would probably take a week. Also, keep in mind even companies as big as Adobe are pain to deal with when these problems happen. In short, you're dealing with dis-connected time-zones, the general slowness of banking reverse-charges and probably some young dis-organized people at Filmpower. I see you make spiritual films. I'm not religious, though I've read and thought about the bible at some depth. My biggest take away is this. The more one believes in God, the more one resists judgment. God is up there, we are down here. The real problem Job faced was not the misfortune placed upon him by God, it was the fact that no one believed he was good on Earth. He knew complaining would be false to God.

Or one of my favorites from film "Bad Day At Black Rock", "A man is only as big as the things that make him mad" BTW, I used to think Tracey said those lines, but it's actually the bad guy Lee Marvin. GREAT, GREAT film if you haven't seen it.

Again, I can relate to what you're going through. I think with a nice walk in some fresh air you'll wake from this bad nightmare.
