Hi guys i am building a gimbal to carry RED EPIC with 2xiPower GBM5108-120T for tilt on single output with reverse polarity on 3 axis alexmos board along with 2xiPower GBM8017-120T for pan and roll each altogether from single board. (connecting 2 motors on tilt output for tilt and another 2 motors for pan and tilt output each.) Is it possible to carry RED EPIC on it with this config or would it be better to use single GBM8017-120T for all axis? can alexmos power 2 tilt motors along with 2 other motors at the same time?
I had one rig working with 2 tilt motors by just using a Y lead and by just reversing the direction in one of the motors. Strangely enough the second time I tried with a new rig it is not working and I dom´t know why....Help apreciated.
mkp that is the way I did before...but on a different rig is not working...might be a faulty board? AOPEN3434 and mkp do you have set the polés the same way? I have 2x 22 poles motors and kept it 22 or changed it?
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?
I might have a problem with the board. Not only the 2 motors together don´t work but also both tilt and roll don´t invert the polarity on the GUI. They keep turning to the same diretion...
what your sensor doing is it behaving where do you have it mounted is it insulated? because if you do not have the sensor orientation set correctly you wasting your time .
The IMU is ok. Correctly oriented and calibrated. The board is not reversing the polarity on pitch and roll when I do so on the GUI. Can only be the 2 axis board as the 3rd axis reverses the polarity as it should.
btwn Pols are (NUM.POLES– Number of motor poles. This value needs to be equal to the number of magnets in your motor’s bell.) So I think its not something we need to tune it as we needed..i mean its the issue here :)
I am building a gimbal with 2xGBM8108-150 for pan and roll, and 2xG5208-200 for tilt axis. Now trying to figure out how to connect both tilt rotors to the same connection on the board. I though about the Y cable solution, but my question is how I reverse one of them… Do I just connect it the opposite way than the other one? Or need an special already reversed y-cable? I am quite new in this world, so I really appreciate your help…
