How to invert the x-axis values?

There is a "negate" function available for this. It is a little cleaner on the BD.

It might just be that the left and right motors are swapped. Make doubly certain that the PWM outputs you're telling the Drive Open to use match the ones actually wired on the robot. There are ways of connecting things and configuring the "MotorInverted" parameters that will give the results you are reporting.

As mentioned, you correct by physically swapping motor wires or multiplying the command value by negative one. For me though, the cleaner way is to look into the begin.vi where the motor definition is. You should see a boolean input to the motor definition vi that allows you to change motor direction definition.

We had the same problem and it turned out that we had our "MotorInverted" parameters backwards, it's a quick fix just change the trues to falses in the begin.vi.
