CORRECTION 0:47 Input coming into the controller such as the start, hold and reset buttons, the probe and limits switches all need an active low signal - which means when the pin is receiving a voltage (normally 5v) it is disabled, and if that goes to 0V is it active. The coolant and spindle enable pins use an active high so the off state is normally at 0v and that goes up to 12v to signal those are turn those on. In the case of stepper drivers a high and low signal result in moving the stepper in one direction or the other. When I built my first controller I didn't use a probe or start/hold buttons, and my limits were simple mechanical limits which didn't require me to investigate how they worked.

CNC Control Box with VFD etc etc
I'm currently working on the CNC control box, before doing any future work on the CNC Mountain Machine. I want the controller to be future proof and as professional as I can manage. I am planning to use stepper drivers, PSU's, a motor contactor unit to turn everything on, as well as a VFD and proximity limits switches. Each video will document the process and steps involved in researching, designing, planning and assembling a controller. I am not a natural electrician so learning as I go.
