Corner LEDs not working
-
R8 is 140R 0.33W. The schematic is at https://github.com/T3P3/SmartEffector/blob/master/SmartEffector/SmartEffector_v1.3/SmartEffector_Schematic_v1.3.pdf.

Thanks David.

Okay so, I ordered a new Smarteffector PCB and swapped it out.
Rebuilt it with the new PCB (LED jumper OFF this time - 24v) and it works fine.
But on taking a look at the old one, the R8 resistor looks a little toasty but still reads 140Kohm.
Maybe it's just not very well soldered?
NB it's worth stating that I am running my smart effector 3 corner LEDs by connecting the hotend fan connector on the smart effector to the heater in parallel as I now have watercooling and the hotend fan isn't wired up anymore, I needed the two cores in my wiring loom for a thermistor for the heatsink. The PWM to the LEDs shouldn't be a problem should it?
-
PWM to the LEDs is OK. As you were previously running the LEDs well above their normal current, perhaps one of them has blown? Let me know if you need a replacement.

Thanks David, I bought another piezo effector pcb, it was my fault they blew, I should have taken the jumper off. I can replace or possibly just resolder the resistor and press the broken one into service elsewhere. I'll check the leds. Hope you had a nice Christmas.

I meant a replacement LED so that you can mend the old one.

Okay thanks will let you know.

The 3 white corner led on / off is possible , or light ever time when printing ?
Thanks -
The corner LEDs should illuminate when the hot end fan is powered, if you have the wiring polarity correct.

Ok thanks for response DC42,
It is boring to always see the LEDs ON, especially at night with long prints. There is no possibility to switch them on / off with a command. Thanks again
