Automatic power supply management

Krohm Koala

@dc42 Hi ! just wanted to know if it was a bit of news about that ?

dc42

As you are the only person who has asked for this, i think it would be best implemented using the daemon.g file that is supported in RRF 3.01-RC5 and later. Let me know if you need any additional object model variables in order to implement it.

Krohm Koala

@Krohm-Koala oh I see i'll search about daemon.g thanks

Krohm Koala

@dc42 is there an object model variable for the state of the power supply ? Also as i'm totally noob in this type of programmation, can't do anything, as everything i try turns to nothing ^^ i'll just continue as it is and deal with it i think ^^ thanks anyway

There is a special status "off" which means that VIN power is not present. That's what you should get when you turn off VIN power. Alternatively, you can retrieve the VIN voltage directly.

~~There is not currently an object model value to say what the state of PS_ON is according to the last M80 or M81 command. Do you need one?~~

dc42

Correction to above: there is a variable that says whether PSON on or off, only available if there has been a M80 or M81 command since reset. It's called state.atxPower.

oh cool ! maybe i'll try something do you think there's a way to automatically turn on psu when an heater need power ? I think there's the only thing i want the most to do, for the other things i needed it at the beginning i overcome with M80 almost everywhere

Krohm Koala

Also, how do you get the status of VIN or VIN voltage to do meta code ? Maybe easier than state.atxPower to be sure there's no false positive or can be using directly at the reset ? Or maybe i can add M81 at the end of my config.g to be sure it's ok since the reset

I'm not sure it will work because of the lag, but in your loop in daemon.g, if power is off you could iterate over the heaters and turn on the power if any target temperature is above 45C.

Yes you can use M80 or M81 in config.g.

I think i'll try something like that ^^ just need to find how to check if the target temp is above some °C and it should be ok it'll be funny to try something like that as i'm a complete noob in coding, i had done an auto change filament script, i think i can do that too

Krohm Koala

Cant validate my code for now as i'm printing but, here is the code if you want to look at it i hope it'll work

if boards[0].vIn.current < 23
....if tools[0].active > 100
........M80
........break
....else
........break
....else
........break

Krohm Koala

So, i made some tests, this is the final version, better and also, look for the head temp or the bed

while boards[0].vIn.current < 23
....if tools[0].active[0] >= 100 || heat.heaters[0].active >= 40
........M80
........break
....else
........break
