I'm trying to test the aprinter firmware before I replace my RAMPS 1.4 board, aprinter is uploaded, I can connect to the board with various host apps but the stepper I currently have connected doesn't move (I haven't connected anything else yet) I've tried it with 3 different stepper drivers in the x, y, and z positions, are there certain things that need to be connected to the board before it'll do anything?
