Bump

This is pretty cool, want to see others commenting on what they'd like to see trigger the color change. I'd like to see during a build what percentage complete I am. Maybe a color switch for 50% complete, then 75%, 90%. Then I could monitor prints from across the room without getting up to look at the screen. As of right now I run a large timer webpage on my laptop screen with the pronterface estimate and I'm pretty close.

Have been playing around with getting some lights to turn different colors depending on whats happening and here is my progress this far:

BOM:

*Adafruit ledstrip: http://adafruit.com/products/306

*Ramps or I guess any board running Marlin with 2 digital and a ground pin free.

*An external power supply for the strip

Instructions:
Straight forward really most of the work is done in the Marlin FW to trigger the event and color changes.
This far I have the following commands working (although my code looks really bad atm):
Power on -White.
Fan on- Green
Fan off- Blue
Homing in progress - Cyan
Homing done - Green.

Not managed to get working:
colorchhange while the bed is heating, I thought this is done by the m190 command, but cant seem to fork to it in a working matter.

Will get back with a better write-up soon.
Ideas for colorchnage on the bed heating would be nice.
