Auto Sweeper not supplying specifically to coal generators

[Mouroz]

I'm honestly not sure if this is a bug or if somehting is simply slipping my mind... yes i saw the old post about this but this time its different:
- I set the conveyor recptacle priority to 1, a storage bin priority to 2 and all coal generators the 8.
- Regarding the automation part i connected the auto sweeper to the same automation wires as the coal generators and always tested when it was on.
- Fuel request threshold of all coal generators are 100
- I disabled mods, but i only had the mod to reroll caracters an the infinite zoom out mod (to see the whole map), i highly doubt any would affect any machinery mechanics, but i still disabled them anyways and even let a whole cycle pass
- No, the only thoing allowed on the bin is coal, and the only thing being supplied to the receptable via a manual loader use is also coal

Emptying the bin and selecting to storage coal again... the coal is immediatly resupplied to the bin that has a drastically lower priority level while the coal generators is on 60% or so, some even on 30% and about to run out... im completly out of ideas on how to fix this, but allowing dupe passage on the power room is gonna affect temp of the base alot, and its also pretty far away and inneficient to have them go there...
It was working fine until i decided to relocate it to add one more coal gen slot but now its completly non functional even after removing that extra coal gen
Is this a bug or am i missing something?

Here's the link of the layout (theres supposed to have 1 more coal gens on that stair place though)

Edit: it seems it was related to the fact that with automated generators, they are most of the time untochable by the auto-sweepers (once battery reaches 50-60% depending on your threshold all the way to once the smart battery automation turn the gennerators on again). If none of the things i just mentioned seem to make the generator work, its probably this oversight right here ^)

Top row power generators probably are not accessible by sweepers because coal power generator tile of interest is middle bottom one.
Coal supplying way is suspicious about avaliability percentage.

This setup works just fine, sweepers reach all.

For me everything works, onlly thing is if you think generators get not refeuled by sweepers then wait, they will do it when generator is almost empty.

Hmmm. I have not been watching explicitly for this, but have noticed that the generators are getting far below the threshold I set before getting filled. I will watch for this.

...Autosweepers only refill coal generators when:

1) there almost empty
2) Sweepers are not connected to automation
3) coal is stored in range

They do refil them no worries, it just ignores all of the generator settings, once you have like 5/10 mm coal left in it then it will refil.

Nope. Does not work that way. Specifically tried this, and it doesn't work. I have the generators hooked up to smart batteries via automation, and wonder if that is messing with it.

Tried disconnecting generators from automation grid. The autosweeper ignored them.

Did you try setting coal generators refuelling threshold at 100% ?

Honestly i find that the autosweeper + coal generator mechanic confused me to this day... sometimes generators reach thresholds lower than 50% before being refueled, not sure its because they are turned off by the automation cable and therefore cant receive anything nor do anyhting.

However it always work for me whenever: they are on higher priority than the receptacle, and dupes dont refuel it. Maybe on your case dupes are uncessarly doing the job of refuelling to coal generator?

You can try assigning low priorities like priority 1 to the receptacle and priority 2 to the coal generator. However if you still have supplier dupes with higher priority set on supplying, then if they dont have anything left to supply they'll still try to supply the coal generator even on priority 1. If this might be the case for you, put on a whatever you deem best door on the path to the generators and remove permission from the supplier dupes to get in, then see if the sweepers work again.

Dont forget about the priorities and the fact that the receptable and the coal generator middle bottom part must also be on reach though.

If you are using smart batteries with automation wire attached to coal generators it will prioritize the smart battery threshold over the fuel request threshold.

I’ve experienced this as well from observation and a bit of testing I think you will be able to resolve this by lowering the priority of the coal generators to 1, your storage container priority doesn’t matter except I’d put it higher than any other coal storage so dupes will bring it here.

What I believe is happening…
Coal generators will request coal at the specified amount; however, if the building is disabled (for example with a smart battery) it will clear it's task queue except to turn it back on or destroy it. So the coal generator is no longer requesting to be filled.

The other issue is if the priority of the coal generator is too high, then a dupe might take the refill task before the auto-sweeper. If the task is assigned no other dupe or auto-sweeper will perform it.

If that dupe is running to do the task and the batteries shut off the generator, then that task is removed (without having filled the generator), and your dupe will go do their next task. With a high priority, the refill job might never get completed if a dupe can't make it in time to refill it.

Tl;dr By having a low priority on the generator a dupe won’t take the task and it’s the only job available in range for the auto-sweeper so it will get assigned.
