You wrote "one or the other", so it doesn't move both Z motors at the same time?

Connect the negative lead of your voltage meter to gnd somewhere on the board/power supply and only move the positive lead to the desired test point when you make these measurements.
Just make sure that you have +3.3v on the reset line, then it should be in the correct state.
Does the computer react when you connect the USB now after the CPU swap?
