Quick question about boot order with an RPi and Duet 3
-
I just looked into the boot process again and I've found a way to prioritise DSF. This way, DCS will start within 10 seconds when the Pi is powered on.

On the subject or wiring the fans as being always on, looking at the wiring diagram https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/6mYpDS1EmhXHobw4.huge it looks like I could simply connect the fans to OUT3 (or 4 or 5) GND and V_OUTLC1.

I may have missed this before but why not use the always-on fan header right above out_0?

V_OUTLC1.
if you remove the jumper that pin has no voltage, use 12v on same header instead.

methinks he has 24v Vin and 12v fans.

???? There is no 12V on that header - but I'm not going to remove the jumper - I'll set it to 12V.

never mind, i thought you meant to use the pin on the voltage selection header, but that doesn't make sense.
you're good to go as planned
