Calibrating with x2

I just got both the arcdroid and the x2. The instructions are not as clear as I’d like for calibrating. It says the x2 should not be connected. Does that mean that the entire arcdroid should not be sitting on the x2 platform (cuz it’s 1 inch higher) or just that the wires for the x2 should not be connected to the arcdroid?

Wires should not be connected. Height doesn’t matter for calibration as your calibrating the movements for X and Y.
