Feels good finally making a genuine guide video again.

Actually very simple how you described it! I will be doing this for sure!

Do you think there would be a way where the gcode could pull temp values and adjust colors based on that temp? I.e. Perhaps some algebraic equation where when the temp increases for the hotend, the leds fade from red to blue. Perhaps its more of a firmware thing at that point.

@Griffin_Paquette ​ you could split heatup into short sections and change color after each, but Marlin 1.1 (and newer) actually has that exact functionality built in!
