Hello. Newb here. I have a brain/controller where the Left drive can only be done by the E controls on the remote. I’ve played with Driver Control settings and “reversed” the L/R controls, etc; I’ve tried other controllers; I’ve tried other brains; I’ve tried plugging everything into VexUpdater but everything is already up to date.
I suspect you have the motor in the wrong port.
The left motor needs to be in port 1 or 7 when using standard driver control mode.
