Well I can say that your followers are set incorrectly (or SysID configured incorrectly). The “L” and “R” listed there are referring to the “left” or “right” motor within the pair of motors (aka, same side of the drivetrain). So, if 4 is following 2, then I would expect both to be connected to the same gearbox, and both to be under the same motor controller pair
There is an issue with Neo’s and SysID in the current live build. You can download a new version that fixes this issue as discussed here:
@Fletch1373 I don’t think that that is the correct way to use the motor controller pairs. What do teams that have 3 motors on a drive transmission do then? We have always set up our config with the motor controller pair controlling 1 left side motor and 1 right side motor, adding as many pairs of controllers as needed for our transmissions.
