IMU faulty?
The conclusion that was confirmed by basecam was that you cannot tilt the frame too far in lock mode. This is a limitation of the current boards (with only a single IMU accessible). In follow mode this is compensated for. Are you in follow mode? …

Quite possibly yes, but there's another situation where a similar thing happens as well (that I've never experience but just read about so can't speak from experience). Just out of curiosity how do you have your IMU oriented?

Just wanted to mention that this behaviour has been concluded in this thead: http://forum.basecamelectronics.com/index.php?p=/discussion/564/imu-faulty#Item_9 Essentially, you cannot tilt the frame too far in non-follow modes.

For anyone following this thread or coming across it due to similar experiences. It turns my suspicions were correct and this is expected behaviour. Also found out that this seems to be addressed by the new 3-axis board with the ability to use a sec…

2 tilt axis motor along with pan and tilt motors from single alexmos board.
The numbers of poles are kept as is on my configuration. As for faulty board have you tried driving that axis from a different physical output yet to eliminate that as a variable?

Thanks for the confirmation. I guess technically where the axis "switch" would be is 45 degrees, but there would be immediate cross axis interaction as soon as things are out of balance. So that means tuning not only has to balance the typ…

regarding the two motors on one output: I have mine wired with a y-cable and one motor reversed. It's working fine.

Furthermore: it seems that the YAW measurement in the IMU works in any orientation and appears to "right itself" in the unit. Am I correct in that assumption? If that wasn't the case then it appears this feedback situation would be mi…

I posted this on my other thread and thought I'd continue here since the issues seem to have merged into one. Theory (that applies to my other underlying problem): The closer one gets to the extremes of travel the closer we get to a condition …

Theory (that applies to my other underlying problem): The closer one gets to the extremes of travel the closer we get to a condition where two different axis line up. As a result we get to a sort of feedback situation where two motors achieve the sa…

Thanks for the reply. Sorry, maybe I wasn't specific enough. The gimbal is generally working fine and has even been used on production so far. I'm trying to improve the performance of it since I'm having problems at more extreme angle…

Indeed. I'd like to get D as low as possible too. Definitely understand the relationship/tradeoff there. It's all a balancing act that's tricky to sort out. Which is why I commented on being so hesitant with the aggressive settings. T…

Back to square one as of today. for me. Crazy aggressive D values don't really work (as I expected) as sometimes it goes into high speed oscillation even under less strained circumstances. So I'm back to trying to see why the first issue o…

I know what you mean. I'm actually enjoying the learning process and figuring out the way all the different things balance out. It makes for a better understanding how a device works...when there's time outside of production time that is. …

Thanks for explaining that kikojiu. That's one of the fields I have yet to play with in the GUI. Unfortunately this problem exists even before enabling Follow mode. That said, the byproduct of using the aggressive high D value tuning setup (tha…

Getting closer. Sorry for the online diary...but maybe this triggers some thoughts from someone that has seen a similar process. Rebalanced: nothing changed. Recalibrated: nothing changed. Even disconnected the yaw expansion board to see if that he…

Thanks for the reply Dave. You're blog posts on the other forum are actually what drove me to build yet another piece of camera hardware ;) To answer your question, balance is good on all axis. I'll definitely redo all the things on your l…
