Brushless gimbal by Martinez and MPU6050

[modifyit15]

View attachment 12580 I bought this brushless gimbal and I can not get it going. If anyone can recognize this unit and can help, it will be greatly appreciated.

Ok here is what I have done I downloaded this program from here https://code.google.com/p/brushless-gimbal/downloads/list its the one for 50/50. I did this on my PC but would prefer to use my MAC

when I turn it on it just Gitteres like a bug.

Hey guys and gals thanks in advanced

Hi Modifyit, don't know how much research you've done on the bg's, but that looks like the martinez board you get from GoodLuckBuy.
Start with this post from SeismicCWave...http://www.rcgroups.com/forums/showpost.php?p=24742063&postcount=3139
Make sure your gimbal is balanced and not just sitting level but able to tilt to one side and hold the position, same with the pitch. When you power up make sure the gimbal is absolutely still while it runs through it's calibration startup.
Sorry I couldn't be more help but I'm still learning this myself. I'm running vers 049B r69 and seems to work alright.

Thanks that was what I needed

Glad I could help. Let me try and help some more although I'm using the rctimer version. It looks like you have your imu mounted sideways, x should point to the front
and y should point to the side, cables out the back and all the board components should face down. Are those 2 holes at the back of the camera tray meant to mount it? Looks like those 3 pins that set all by themselves are for your pitch so you'll want to run a servo wire from there to a switch or knob on your Rx and assign a channel on your Tx to control it. but disconnect the red wire at one end or the other and tape it back, the board provides the power, you just need signal and ground.
Another tip- put some kind of extension on your boards power pins to make it easier to connect a battery, it's way to easy to short out your board by giving your ground plug power.
You'll be surprised how well they work when they're tuned, this is an excellent tutorial on tuning-http://www.rcgroups.com/forums/showpost.php?p=24983487&postcount=1497 (sorry Bart for linking to that other place but not a lot of info here yet)
They're not plug n play and I've had to deal with a lot of things out of my comfort zone-arduino, windows, pids, but for what these things cost and what you can get out of them is really amazing considering the quality you got out of a $150.00 gimbal just 6 months ago.

Now that all that is done my problem is it seems the motors are not strong enough to hold just the weight of the gimbal. is there a setting for hold strength.

What size motors and weight of the camera? I am just about to get one of these and want to make sure i choose the right motor

 

[modifyit15]

it all came as a kit I'm not sure what size motor is in the picture

If you dont have the gopro in the gimbal it will be horribly out of balance and it wont work if it is badly unbalanced.

Also make sure you're hooked up to the battery power you plan on using when you tune your board, you can also have the usb plugged in at the same time. Make sure you route your imu cable so it doesn't bind, I had a heck of a time retuning and retuning trying to get the tilt to return to level and it ended up being the cable hanging up at a certain spot. These micro gimbals are all about balance, use a small binder clip and move it around the axis you're having trouble with, see if your balance is a bit off. Did you ever play that game as a kid where you take 2 magnets and try and magically push one around the table using the other magnet? You had to find that sweet spot where the distance between the 2 was perfect and you could make the magnet go where ever you wanted, that's what these gimbals are like, constant search for a sweet spot.
