Disable Z Probe

After dealing with an inductive Z probe that returned imprecise results I switched to manual bed leveling on my Printrbot Simple Metal and removed the errant sensor.

I'm worried that if I accidentally click the home-Z button that the printer will crash the hotend into the build plate. I'm loath to leave the sensor plugged in with foil wrapped around the end, as it just seems like a poor solution. Is there a way to disable this sensor/gcode in Marlin without recompiling?

I don't know what your inductive probe puts out for a signal, but you could tie that pin either high or low so that the firmware thinks it is untriggered. But really, compiling the firmware is so easy and it really is the right way to handle this.

Thanks, I'll look into getting things set up to compile Marlin.
