Yes, just woken up, its morning here

Will have to think about Enable 2 not working, have something in the back of my head thats telling me there has been mention of it before but cant think of it at the moment.
How would you be wanting to switch on the light or fan and when would you want them on? might be better to have these done in your machines wiring rather than with an output, for example on my lathe I have the fans coming on when my servo drives are powered up, same with the light, if I hit the E-Stop button that switches off everything on the lathe including drives, fans lights etc.
You can make up buttons on screen to work outputs, you can use for instance the coolant button to do this (if you dont use it for coolant ), you could use a macro and either use a button or G Code to switch it via the macro, could use a brain in a similar fashion, just so many ways to do things its not easy to tell you how unless we know what you want and when you want. We know you want fans and lights but when you are wanting them to operate determines how you will do things.
