We’ve recently been testing using brushless Neos for our drivetrain this year. However, when we drive around, pretty consistently the front right spark max doesn’t move. The status light is a blinking cyan, even though there is a command being sent to it, so it should be either green or red. Even connecting through a usb to the controller and manually setting power there doesn’t work either.
The spark max controller is connected to the brushless neo motor with the 3 wires and the encoder. On the robot, it receives power from PDP, and is daisy-chained for CAN communication. The CAN daisy chain starts at the RoboRIO and terminates at the PDP.
We’ve swapped out the Spark, and it started working for a bit, and then it stopped working. We then swapped the old Spark back in, and it started working again, for only 10 minutes. We swapped the motor it’s connected to as well, and that worked for a little bit before failing again.
I tried upgrading the firmware to the latest version, but then the dashboard started reporting an error where the firmware version of the spark I just reimaged was too low. However, I triple checked that the firmware I flashed was the latest version available from the website.
Has anyone else experienced a similar problem?
