5V Fans on Smart Effector
-
Just wondering if we can use 5V Fans on the effector or not?
I am guessing yes but the LEDs would be dim.
Just wanted to check before spending the cash on what tend to be quite expensive fans.

If you used a 5V fan for the heatsink fan then the LEDs probably wouldn't light at all. No problem with using a 5V print cooling fan.
-
it was the heatsink fan in particular but I can live without the LED's abhor maybe there is a work around by adjusting a resistor or two but i wouldn't what to change either.
But thanks for the info

Hi Doug my mod is connect the leds in parallel with the heater not the fans then you get a visual representation of the heater status. Quite bright even when maintaining temp, they don't flicker the pwm frequency is high enough.

I assume likewise that the 12v fan would be okay too then? I got a Noctua 12v without thinking about it for cooling fan and I have a 24v hotend/psu. I have a step down to 12v accessible but would like to use the effector if possible.
-
Yes you can use 12V fans on the effector, with the 12V jumper fitted to provide sufficient current to the LEDs.
-
Oh okay so the 12v jumper doesn't affect the hotend then?
-
The 12V jumper just shorts out part of the series resistance for the LEDs. The LED string + series resistors are connected in parallel with the hot end fan.

Awesome! That's great design - can't wait to get the everything setup on my big delta.
