Specifying hot end fan for toolboard
-
@jens55 in the m106 for the second tool fan you're referencing heater 1 and not heater 2
-
Dooohhhhh .... thanks, I will give that a try.
-
Yup, that was it .....
Related question - why, when I have specified heater 1, did the fan on the second tool not go on when the first tool is heated up (fan on the first tool turns on like it should but fan on the second tool doesn't even though the same heater is specified on both) -

@jens55 if you read the Firmware Limitations part of the Duet 3 guide then you will see that the thermostatic fans connected to expansion boards can only be controlled by temperature sensors connected to the same board.

Thanks !
If I wanted to turn on lighting on the printer if any hot end is over 45 degrees, how would I do that ? -
@jens55 daemon.g and the object model

@jay_s_uk, thanks!

If I wanted to turn on lighting on the printer if any hot end is over 45 degrees, how would I do that ?Either use daemon.g as already suggested, or configure the LED as another thermostatic fan, attached to the main board. A thermostatic fan can respond to several sensors.

Thanks @dc42, that is actually the preferred method rather than daemon.g. Can you point me to a code example by any chance ?

Just create the "fan" using M950 as usual, and when configuring it with M106 give a list of sensor numbers in the H parameter, for example:
M106 P5 S1 T45 H1:2

@dc42, oh, that is a lot simpler than what I had figured. Thanks!
