You can connect ALL of your home and limit switches in series and then you will only need to connect to one pin. You set all these limits and home switches up as the same pin in Machs Ports and Pins.
You could set the tool sensor up to the same pin as the E-Stop but that would just be trouble as when the sensor was hit Mach would instantly stop the pulses and the axis would likely travel further than Mach thinks it has. You should never use the Stop button when an axis is in motion or you will loose position and need to re-reference.External E-Stop and the Stop button in Mach are meant for Emergency only.
