Adding Panel indicators to Bed, hotend
I have a Duet Maestro board and would like to add some indicators to give me a visual indication of what is active.
For instance, where the hotend plugs in I am using the screw terminals, could I connect an led indicator to the 2 pin molex as well?
Yes, you can connect an LED + series resistor to the heater output pins too, in parallel with the heater - just like the LED + resistor that is already on the Duet.
Thanks DC, not sure what you mean LED + resistor.
I have ordered some of these. Are they OK? I am running 24v.

@paulhew Yes, those will be fine.
Thank you for your help. Have ordered them.

A bare LED cannot be directly connected to any arbitrary power supply — a resistor usually needs to be added to limit the power to the LED based on its specifications.
The panel mount led you bought likely has a resistor.
