Hey ksw,
if you press the mushroom-shaped red button on top of the Onefinity controller box, which is a so-called kill switch, the power to the internal power supply will be immeditately cut. It will however not take care to stop spindles and routers, it will just cut the internal computer from power brutally. I know no case in which it would make sense to press this button, because it does not take care to also stop routers and spindles connected to the machine. An emergency poweroff switch should always but the entire setup from power. But usually you don’t want an emergency poweroff but an emergency stop. This is something different.
To make power come through again, you got to lift the button up again.

The physical mushroom-shaped button on the top of the Controller box has nothing to do with the similar-looking icon on the top right corner of the User Interface Display. The latter enters so-called estopped mode which will stop all motors including spindles attached via RS-485 Modbus interface, pwm spindles, and routers attached via a relay on pin 15 (‘tool-enable’) of the 25-pin I/O port.
The physical button on the top of the Onefinity Controller box DOES NOT enter this estopped mode, but simply cuts power from the internal power supply. IT DOES NOT take care to do anything like stopping spindles or routers.
If you want that the physical red mushroom-shaped button on the top of the Onefinity controller box triggers real estopped mode, you got to rewire it to be connected to pin 23 and ground of the 25-pin I/O connector and activate it on the I/O page. ONLY THEN it will do the same as the red-yellow estop icon on the top right corner of the User Interface Display, which means, it then will take care to also stop spindles and routers connected over a relay.
It has been reported that users hit the physical red mushroom-shaped button on the Onefinity controller box so hard that it was internally broken then. In this case you could open the controller case and simply bypass the buttons wires to make the controller run again.
