Is it possible to start and stop the Makita router thru a relay controlled by the longboard?

@Jimbaker Yes it is! I have the digital loggers IOT relay from [here](https://dlidirect.com/products/iot-power-relay). You can connect it to the coolant control on the control box then turn the router on with M8 and off with M9. I modified the grbl mm post processor in V-Carve to automatically put M8 at the end of the “start” code and at the beginning of the “end” code.

It has 4 outputs. One is always on, two turn on with coolant on, and one turns off with coolant on. I run my vacuum and the router from from the two normally off and on with coolant. I use the always on for my raspberry pi that runs my camera. I haven’t found a use for the normally on, off with coolant on, one yet.

@Jimbaker Take a look here

> [@IOT Relay Setup for LongMill](https://forum.sienci.com/t/iot-relay-setup-for-longmill/3585):
>
> If you wish to have your router turn on and off at the response of different g-code, you can use an IOT relay. To control the IOT relay, the g-code can be activated with pre-programmed buttons (“macros” or “events”) or manually added into the g-code file. The instructions on how to wire up and add g-code for the IOT relay are found below.
