What's this orange led on Smart Effector?

[Nxt-1]

I last week I replaced the wiring loom to my delta's Smart Effector. Now I notice an orange led that is on on the effector and I don't recall ever seeing it before. A quick look at the smart effector doku page doens't provide any description on what the lead means, not did I find anything by searching "orange led" on the forums.

Heater indicator I..think

@Carlo I just took a look at the schematics and I believe you are right. Led D4 is a hotend heater indicator. Right now I am kind of baffled as to why I don't recall ever seeing that led on(or any orange led on duet product for that matter) in over a year of usage.

Perhaps you had the Heater+ and Heater- wires swapped?

@dc42 That would make sense.
