Hey GregZo,

this is a good idea since usually you want the emergency stop button to be in good reach when operating the machine. However the big red button on top of the Standard Series Onefinity Controller box _is not_ triggering the Estopped mode of the Onefinity Controller.

As Onefinity [stated here](https://forum.onefinitycnc.com/t/estop-or-black-square/9286/5), their Hardware Emergency Stop button is **not** wired to the “estop” input of the [mainboard](https://github.com/OneFinityCNC/onefinity-pcb/blob/master/Schematics/onefinity-cnc-rev5.pdf), but interrupts power to the entire controller at the internal power supply instead. Therefore it is not advisable to use this big red E-Stop button on the controller’s case AT ALL, for the [reasons explained here](https://forum.onefinitycnc.com/t/estop-issue-not-turning-on/10165/2).

So it’s the ideal opportunity to wire the big red emergency button in a way that it _really_ triggers the Controller’s ESTOPPED mode with the benefit that router or spindle **are stopped too** (which would not be the case if you only lengthen the wires to which the red button is now connected).

How to connect the red button so that it triggers the emergency stopped mode of the controller [is described here](https://forum.onefinitycnc.com/t/estop-wiring-via-breakout-board/6983/3).

Note: In estopped mode, a spindle’s VFD is sent the STOP command (that according to the updated IEC 60204-1 is a “Safe Torque Off” (STO)) via ModBus or via safety circuit wired to controller, but in order to switch the Makita router off too, it needs to be connected via a relay e.g. like this [External IoT relay](https://dlidirect.com/products/iot-power-relay) ([FAQ](http://www.digital-loggers.com/iot2faqs.html)) to the ‘tool-enable’ pin of the [I/O port](https://buildbotics.com/manual-v1-0/#25pinioport) of the Onefinity Controller with a [Breakout Board Adapter](https://www.onefinitycnc.com/product-page/breakout-board-adapter) ([see thread here](https://forum.onefinitycnc.com/t/tool-enable-m15-breakout-board-auto-turn-off-on-router/720)).
