This feature should be implemented by the controller, lasergrbl simply send the standard command that is intended to turn on off the coolant but it is responsibility of the controller to implement it. If it is not implemented by the controller, there is no way for lasergrbl to control it. |

It's not for the laser fan. It can be used to toggle a seperate fan for exhaust or extra cooling, or something like air assist or even lighting around the inside of a case, if your laser is encased. The 5 volts can be used to switch a transistor for low power equipment or a relay to allow you to run higher powered stuff. I did a quick video with a multimeter connected to check the voltage. |

This function exists in the last version of the LaserGRBL Customs Buttons (CustomButtons.gz) from the web site and the toggle fan doesn't react.
Any advice ?
