GT2560 A+ Attaching multiple cooling fans

Post by engrost » Tue Sep 29, 2020 10:46 pm

Hi, Have Prusa I3 Pro with GT2560 A+ board.

Want to extend it with Dual extruders, and want to add more cooling fans.
I was thinking of using this design https://www.thingiverse.com/thing:2251319 for attacing fans, but could nowhere find any information where to connect extra fans.
I have only one set of pins for PWM fan on board.
how would I attach more than 1 fan?
are there any other I can use?

Hi Engrost,

I had the same idea, and the solution is: Build yourself a Y-Cable to split the one PWM Signal to both fans.

I have this solution working, Power consumption is ok with two 5015 fans, 0,18A each.

Regards,
Martin
