I'm Curious about what exactly this means "Up to 5x more precision with the new PID (increase I-term until oscillation starts and than reduce a little back to get the maximum from it)" and this (GUI): new setting for additional POWER in case of big error (caused by missed steps) (GUI): new setting to enable estimation of the frame angle from motor's poles in the Lock mode, like in the Follow mode before. Helps to increase the range of frame angles where gimbal's operation is stable.
You'll have to go through all PID settings and readjust with this new firmware. My old settings produced erratic behavior. The new power setting is working well. It automatically increases power if an axis skips a step, my gimbals seems to have more power and torque Still playing with settings.
If I can remember it was somewhere around 6lbs this is with downlink and 1500 mah 15c 4s lipo to power the gimbal/downlink. One thing I'm having an issue with is Yaw follow with the new FW...can't get it to work. I do see high-speed rolling and tilting has been greatly improved. It seems now when I violently roll and tilt the frame as fast as I can both axis hold firm which is amazing to me.
I tested new firmware. In last firmware yaw only worked with follow mode, now it works only without it ...strange. Pids seem to work similarly with new firmware. I am still having problems with fast forward flight, when camera pointing forward also. Maybe pan axis is too weak with rctimer 4114? Camera is GH3 12-35. I need to use very high power and P value in yaw axis.
It was too complex checkboxes in GUI for dummy like me. You have to enable ex. "Follow flight controller" -box and then "follow yaw" setting works. Roll and pitch can be left zero. Now I think new firmware works pretty well. I have settings with or without follow mode in 2 profiles, can choose with board button. Long click enables/disables motors, which is good if you want to have gimbal powered in field but do something with camera.
Hi guys, I wanted to get some feedback on my brushless gimbal tuning. It seems to be pretty good at 24mm which is a focal length I am used to shooting for aerial. I seem to be having a good bit of horizon drift on the roll axis though. I was hoping someone could point me in the right direction. This is a nikon d800 with 24-120mm lens with vibration reduction on brushlessgimbals.com gimbal with 8018 on pitch and roll and 8017 belt reduction on pan in a 4 to 1 ratio. alexmos high power board PID settings: P I D power # of poles Roll 16 0.3 18 180 42 Pitch 12 0.3 8 153 42 Yaw 10 .19 12 175 112 gyro trust 100 accelerations compensation off gyro high sensitivity on password: 24mmlens
Looks pretty smooth, but I can definitely see some jerkiness and horizon shift. The jerkiness could be in the airframe or vibration isolators, not the gimbal. You also need to clean the sensor on your camera. One of the problems of using a really small aperture (like f16 or so) is that sensor dust becomes very sharp. Strange how that works, huh?
Thanks for taking a look steve. How would you suggest I go about fixing the horizon drift? Do you think I need softer dampeners on the echo quick release?
I’ll have to leave the horizon issue to others. I’ve had the same problem. But the quick release is certainly a suspicious part of this. If there’s any flex in it, that could be the cause of some of your issues. Can you eliminate it and test without it? I don’t use the QR systems, and I know others who have had issues with them.
I'm wondering if the gyro trust setting is a good place to start for horizon issues. Have you played with that? I have mine set to 100 but curious how well it would work dropping it to 50 or up to 150. I can't tell from the description which direction works better for holding horizon. The quick release I have is pretty good. It's a solid hard mount to the frame and has different dampeners and adjustable stiffness. I can't tell if I need to make it stiffer or softer. Does it look like I am getting hard mount vibration or rather wiggle from soft rubber?
Increasing the I value should help recovering from horizon problem faster. Gyro trust should help also, mine is set to 200 as far as I remember. Also, 6-way IMU calibration should be done perfectly to overcome the horizon drift problems.
What is the procedure to doing a 6way calibration? I've seen so much conflict ion information on that. What order of positions do you do it in? Do you press write after each position? Can I do it with the imu on the gimbal? Thanks in advance.
Has anyone had problems with direct drive on the yaw axis. My problem is that with a more sudden pan/yaw I believe the CS8 vibration isolators are giving and somehow confuses the gimbal and it yaws/pans in normally the opposite direction and doesnt stop until you counteract it and sometimes vibrates when you try to stop it. using the setup from brushlessgimbals.com with yaw set as follws.
