| - | ===== 6.4 Connecting both an IOT Switching Relay for a Router, and a Laser, to the BlackBox ===== | ||
| - | |||
| - | If you would like to fit both a spindle and a laser to your machine: | ||
| - | * Grbl only has one PWM output | ||
| - | * Easiest method to share this signal between multiple tools, it so add a Single Pole, Double Throw switch to direct the PWM signal between the two devices | ||
| - | * This can also act as a Laser Disarm switch, preventing the laser from firing (safety) | ||
| - | |||
| - | Wiring is as follows: | ||
| - | * PWM from BlackBox, to COMMON pin of switch | ||
| - | * PWM out from one side of the switch, to PWM IN on the Laser Module | ||
| - | * PWM (ON/OFF, as the IoT doesn' | ||
| - | * You can substitute the IoT Relay with Router for other PWM toolheads - the concept remains the same, the switch directs which tool sees the PWM signal from the BlackBox | ||
