Limit switches don't home correctly when gantry close to home

I’ve put limit switches on my s03 with some homemade brackets. I’ll probably make real mounts out of aluminum sometime (anyone have a 3d model for those?)

Anyway, my cobbled together brackets reduce the table area some. I think I’ve set the area correctly when I try to go to edges the machine stops where it’s supposed to. It homes correctly so long as the gantry is 6-8" away from home in the back corner. If I stop the machine closer than that, then cycle power and home, it keeps going even when the limits are hit.

Any idea what’s going on?

Please review the configuration per:

If nothing there helps, please post your Grbl settings and Carbide Motion preferences and the specifics of your electronics (NC or NO switches? &c.)
