I have some light towers that I would like to install on my CNC. I have searched for weeks to find a way to integrate it but have not found a way.
If you have never seen any type of manufacturing machines, this is what a light tower is... https://www.google.com/search?q=machine+light+tower&biw=1366&bih=667&tbm=isch&tbo=u&source=univ&sa=X&ei=6xjpVIGNKsGTNrzbg6gH&sqi=2&ved=0CEYQsAQ
The focus of tinyG is motion control, with limited support for related signaling for spindle and limits.
Light towers are more about Machine and Job control, as a general observation.
I bet you could implement something in Chilipeppr, using the GPIO capabilties, and formulate you own criteria for the colors you have available.
Or, you could have CP turn your cell phone into a light tower.
