I got little bit lost here. I am building plasma cutter. Actually by definition it is even 2.5 axes. But ok, let's say it is 3 axes because i have only X, Y and Z. But on X (or Y whichever is longer) I have 2 motors. One on each side. So literally I have 4 motors. What board do I need? 3 Axis or 4 Axis. I am thinking about these bords 3 Axis 4 Axis i mean there is no problem not a big difference in the price I can simply by 4 Axis to be sure. But my point is to understand. Can I connect 2 motors to one axis and somehow let it spin to opposite directions or I have to use separate axis for that? Another words how second motor is connected?
