I just upgraded from Duet Wifi with RRF 2 to Duet 3 mini 5+ with RRF 3.2.2 and SBC. It's an awesome system, and I especially like the object model. I have a few questions about ATX power:
On Duet Wifi, PS_ON was off (high) by default, so the board started with power off. On the 3mini, it seems to be on by default (low)? If I put an M81 into config.g, the power is briefly on and then turns off.
I'm using a pull-up resistor to make sure that a floating state is interpreted as off, so that shouldn't be the problem. Am I doing something wrong or is this the intended behavior?
state.atxPowerentry in the object model seems to always be set to
false, even when power has been turned on. The web UI reflects this; if I turn on power and reload the page, the switch is shown as off again. Is this a bug or something I've misconfigured?
