Activate effect when extruding

[bertenvdb]

Hi, I've made a simple arc welding effect for my StealthBurner nozzle leds. It's not perfect, but I'm happy with it for now. But at the moment I activate the effect in my PRINT_START macro en deactivate it in the PRINT_END macro. It would be super cool if there was a way to have the effect active only when extruding. I couldn't find anything relevant in the documentation, so I guess it's not possible at this time and so this issue is a feature request.
