Bolt not applying thrust to one motor, but responsive(?)
Posted: Tue Apr 13, 2021 7:54 pm
Hello!
I am currently working with the Bitcraze Bolt, and I am emulating the following Bitcraze blog post as closely as possible:
https://www.bitcraze.io/2020/10/testing ... ll-li-ion/
It is going well so far, however, I am having a problem where when trying to take off the drone does not apply any thrust to Motor 4 (M4, front-left) of the drone. It seems to be able to apply uniform thrust to all other motors, however. I switched the working motor and ESC on M3 to be connected to the M4 position and this motor remains unresponsive, leading me to believe this is not an ESC, soldering, or motor issue.
What I found strange is that if I allow the drone to sit turned on, but disconnected from the cfclient, it will eventually go into the beeping sequence (after maybe.... 5minutes of sitting?) where it very slightly twitches each of the four motors as it beeps. During this cycle it is able to move M4 just as much as the other motors, which makes me think everything is connected properly. Any thoughts on why I might not be able to get thrust to my M4 motor for take-off?
I did find a separate recent forum post that was very similar, however they are doing a much larger drone with a single ESC, which I figured was different enough from my application where I am emulating the bolt/li-ion build at the link above which has 4 separate ESCs.
This is the similar & recent forum post: viewtopic.php?f=5&t=4697&p=21487&hilit= ... tor#p21487
Any thoughts or recommendations would be greatly appreciated! I would share a picture but I cannot seem to find how to do so...
Thank you,
Chris
