MakerFarm 10" i3v build

There's nothing wrong with wiring them to D9, but you'll have to remember to tell your slicer to enable cooling so that D9 gets turned on for the print. Personally, I'd save D9 for the option of adding a print cooling fan. You may find you want those LEDs on more than you think - when checking bed clearance, when manually extruding after a color change, when wiping off the hot end nozzle, etc. If you followed my LED scheme, note that clough42's revised hex hot end shroud system uses a different baseplate on the X-carriage that has a 25mm fan right where you probably have those undercarriage LEDs.

Very useful details, thank you. I hadn't thought about the other ways the lighting might be useful.

Actually, the need to replace the baseplate for clough42's fan is a big concern I've had. Among other things, I worry that the ABS might heat up and sag.

How is your pot holder/trivet that you mentioned in your build thread working? I think the cardboard I'm using isn't providing enough insulation and this causes the bed temp to drop from 110 to 100 during the start of the printing process (I'm doing ABS right now). I will mention that I did apply Kapton tape the underside of the bed per your idea, to prevent scratching the traces while removing the clips.
