New build with recycled parts on a ridiculous budget 120cm*60cm work area

I've run the X axis (Gantry) to the X input and the 2 Y Axis limits to Y & Z, when I add a Z I'll add it to the the same input as the Y but will get better electronics than this BOB soon but have other things I'd rather do first.

I thought you was connecting up the home switches before. The limits can all be connected in series together.
