Here is a few mods to add additional LEDS to mine.
Main picture with all 3 strips installed.
This is using high density LED strips of warm white LEDS to replace the original single cold white strip.
You might also notice my now insulated heater block with ceramic and kapton tape.
LED plugs into the the 12V constant on on the extruder head breakout.
Specifically the top right corner one I labeled LED.
Showing the 2 main strips on the sides.
I stole the one from the original strip. for the main side LED and simply ran them in a serial chain since they are meant to connect end to end.
Yes, for the fans and that output at the head, JST XH.
