-===== 2.1.3 Configure the Relay Output ===== 
- 
-OpenBuilds BlackBox has an onboard Relay: Using the Jumpers you can select which GCODE Commands activate the Relay. 
- 
-This allows you to use the relay for various purposes:  
- 
-=== Disable the Relay === 
-Typical for Lasers, or when you have a Spindle wired to the PWM/0-10v (VFD) Terminals, you are using the [[docs:blackbox-x32:connect-dewalt-iotrelay|IoT Relay]], or when you are using a Servo  
- 
-With the jumper removed the PWM signal will not be sent to the relay (which would make it chatter) 
-

- 
-=== Respond to M3/M5 Tool On/Off Commands === 
-Typically used when you have the Onboard relay wired to control a Plasma inverter 
- 
-{{:docs:blackbox-x32:relay-m3.png?200|}} 
- 
-=== Respond to M8/9 Coolant On/Off Commands === 
-Typically used to wire a DC-powered air solenoid or water pump to do coolant/chip evacuation via the onboard relay.  For mains powered coolant options (Mains water pump, vacuum cleaner) we recommend using an IoT relay instead

- 
-=== Respond to Spindle Direction Commands / Use with Grbl's "USE_SPINDLE_DIR_AS_ENABLE_PIN" === 
-This is not typically used, it exists for esoteric configurations that cannot be controlled with PWM/0-10v only as one would normally do instead.  
-This connects the relay to Grbl's spindle-direction pin.   M3 should activate the relay, M4 should turn it off (as the relay is single throw, the counter clockwise signal, turns it off)  
- 
-To use it as an enable, rather refer to Grbl's "USE_SPINDLE_DIR_AS_ENABLE_PIN" function: In the [[https://github.com/gnea/grbl/blob/40eb439bf2afc4c6f3003836c396e183ba72c45b/grbl/config.h#L352-L360|Grbl Configuration File]] for a compile-time option that allows you to control the relay as a spindle-enable. Then it responds to M3 and M4,   with M5 turning it off. See Grbl source comments for more info
