Fan Control, no Ground for Fans
taconite last edited by
just a quick question. I build a delta style printer and the Fans (Hot End cooling fan and part cooling fan) are mounted on the effector. To spare wires to the effector I use one ground cable for the fans (and other stuff), that is why I only connected the Fans to V_Fan.
I guess that is why I can't control the fans. Because those are just 2pin fans, is it possible to connect it to Fan0- or does this damage the fan/board/both (as stated in the wiki).
I guess not, but is there a work-around possible?
Why is the PWM done with ground and not V_FAN?
I hope my inquiry makes sense
