G'Day All, Hoping for some help, I now have my cinestar 8 and 2 axis gimbal. I don't have radians, as the two axis will be sufficient until the movi arrives. I have a problem where by the gimbal on start up has a strange behaviour, the gimbal roll and servo leads are plugged directly into the mikrocopter board. However when I power up the machine after about three seconds, the gimbal rolls to full lock to the left and simultaneously tilts down to full lock, it stays there for about a second, and then returns to level, and operates perfectly for the duration of the flight. Is their something dumb that I have done, or is this standard behaviour? Thanks Chris
Chris: Going from memory (it's been a while since I ran the MK FC board to control a gimbal), I think that's a normal power-on, calibration spasm. I seem to recall some folks putting in a servo power switch so they could fire up the FC board and only when it had come up and stabilized and done its "twitch," would they turn on the power to the servos. The problem being that on some cameras the power-on spasm would bang the lens on the ground. Other forum members might be able to recall the details better than I can. Andy.
Thanks Andy and Gary, it had the look of a start up sequence, I was concerned of the d800 being driven into the ground. I will just lift the bird up until the sequence is complete. Let the flying/learning continue Thanks Chris
hey Chris, yes its pretty standard I remember seeing this in another forum http://www.mikrokopter.us/the-gener...-firmware-to-stop-camera-operator-complaints/ this might help you out!!
I thought this went away about the time .80 was released. That's why I asked what version Chris is running.
Hi All, Double checked the firmware version and it was 0.90j ... does this mean it is potentially the parameters that are for the servo limits that may be incorrectly set? Sorry, I'm somewhat new to this caper.
Chris do you have two fc? one for the gimbal one for flight control? I dont know about changing parameters with the flight control board but if you have a second fc for the gimbal I would go ahead and change them following this video
Yeah I just looked at the mk wiki. I would NOT go changing those parameters with just the one FC. down the botton it reads This configuration parameter found in the official version of the Flight Software / NaviCtrl not apply. Here, no changes can be made. Therefore, all settings are left at 0. The User parameters facilitate the handover to the MikroKopter for testing, special or debug versions. http://www.mikrokopter.de/ucwiki/en/MK-Parameter/User Looks like you may be stuck until you upgrade or change something!!
