Set of multiple fans triggered by multiple individual heaters?

[gnydick]

I have 2 fans on my print carriage as I have a dual extruder setup. I would like them both to be thermostatically controlled and both of them to turn on when either heater turns on. Is that possible?

Yes you can hook up thermostatic mode to multiple heaters.

So your code might look something like this:

M106 P0 H1:2 T45:65 ; fan0 controlled by H1 and H2, ramps up from 45-65C
M106 P1 H1:2 T45:65 ; same for fan1 output.

If they will always be controlled together you can just use one line of the above and connect both fans to one output.

oh, duh, i forgot about using ':' for specifying multiples. Thanks!
