Multiple Fans for cooling
-
Hi,
I have my Berd Air working just fine on F0. However, I would like to add a couple of fans . My question is, how would I get F2 & F3 to turn on/off at the same time as F0?
Thanks.

@guitartoys Depending upon the current draw of the fans, and the current capacity of the output port, the easiest way is to simply wire them in parallel and power them all from one port.

@kb58 Yeah, it's just that I wanted to keep the BerdAir on one ID and the fans on another. I'd be happy to wire the 2 other fans in parallel.
I guess I could just manually turn them on, once the 1st layer was printer. I just thought for sure this was something that was already thought of.

@guitartoys I didn't answer your question directly, partially because you haven't said what your control board(s) is/are, and what software you're running. I also didn't answer because I'm not sure how to do what you're asking!

If the fan headers being used are the usual Fan0, Fan1, Fan2 etc you can bind multiple fans to the same tool definition.

ex: M563 P2 D0:1 H1:2 X0:3 F0:2 ; create a tool using extruder drives 0 and 1, heaters 1 and 2, with X movement mapped to both X and U axes and fan 0 mapped to fans 0 and 2For more specific answers you need to show us your config.g and tell us where things are connected.
