Just today, my extruder motor stopped responding to commands/prints. I tried swapping the wires for my extruder and x motor. Then, when I sent a command to “move x”, it extruded. But when I sent a command to extrude, it didn’t move the x. Nothing happened.

Does this mean the extruder port on the Rambo is bad?

Thanks.
