Adding fan for nozzle cooling

Post by DAT » Tue Feb 16, 2016 11:23 am

Can the unused 12v header pins next to the extruder and control board cooling fan connectors on the aluminum Prusa i3 sanguinlololu board be utilized for a nozzle fan ? If yes, would a 12v 0.1A be OK ? Thanks

Hi,
I'm beginner too.
I found a documentation for GT2560 (for prusa i3 Pro B), i "understand" 5A max on PWM-FAN connector
I designed a part to add 3 fans (12v). I want to plug all on PWM-FAN and my question is:

How many power can i use on this connector (amp) ? I don't want burn my motherboard, ;)

thx for your answer

Did you end up adding a fan for your nozzle? If so how did you end up doing it?
