You’ve clearly already put some thought into this.
I don’t know if there’s an unpublished shortcut for Fire but I somehow doubt it. And LightBurn now has no provision for scripting multiple actions, any automation, or any API to tap into currently.
So if you wanted to make this happen you’d have to do it externally from LightBurn. There are many UI automation tools that could be leveraged to interface with LightBurn to press Fire. So you have a multi-layer solution:
- foot switch hw
- signal receiver (from switch); easy if switch acts as a keyboard.
- command mapper + sequence manager (equating signal to multiple actions); depending on the final solution. Ex. multiple switches for multiple actions as you’ve indicated; time delayed job start; foot-down for fire, foot-release for job start; multiple switches are probably the easiest to implement but may be a little confusing to operate at times.
- UI automation (to interface with LightBurn)
- LightBurn setup with variable text and the usual config - assume you’ve already got all this sorted.
If LightBurn did have a keyboard shortcut for Fire then this could be dramatically simplified as long as you were using discrete switches for each function.
