#Why am I occasionally getting throughput dips when the input is backed up?

Occasionally my throughput on this belt will dip below 100%. It's definitely having downstream impacts. But the input is a backed up train unloader and nothing more. That backed-up train unloader should just be spitting out shapes at 100% rate, right?

Try upgrading to 0.0.8 ( #✨updates ) and see if it's fixed

solar moat
#

Oof, okay. Bug. Thanks.
That suggests that this also is a bug. Hrm. Experimental build, huh? K. Thanks!

buoyant tundra
#

As a temporary measure you can replace the spacebelt ends

solar moat
#

I went ahead and went to 0.0.8.... which still had a few flickers of throughput problems at the start, but they maaaay have gone away? 🤔
Did you mean literally just delete and replace the ends of the spacebelt?

#

Still seeing throughput issues downbelt on later platforms, but that may just need time to filter through... 🤔 I'll give it 0.5-1 hours and see what happens.

#

No, by this point I would have expected it to sort out. This is one of the earliest points in the entire supply chain, and it's still dipping occasionally.

#

Wait. Might this be doing it? Using too many rotators?

#

No, wait, the problem is even earlier than the rotators.

solar moat
#

Okay, no, 0.0.8 doesn't resolve this non-train issue. I deleted the end of the entire delivery chain to force a 'backup' of everything to the source, then rebuilt the end to start it flowing again. Within a couple minutes I was seeing as low as 89% throughput in some sections, and I've traced the throughput issue all the way back to the source miner.

Have I built something fundamentally incorrectly, somehow? Or is this truly a bug? Or am I misunderstanding something? I don't think this is a problem with upstream utilization, because I'm seeing gaps down here at the source, not stops and hitches.

buoyant tundra
#

Are you seeing that same throughput on the belts on the extractor itself?

solar moat
#

Wait... 🤔 Now I'm seeing blocks and hitches down here at the source.

#

Somehow my problem shifted from gaps to blocks. Gotta check the other branches.

buoyant tundra
#

Yeah, that could do it too

#

If you have a cutter platform downstream, one side could be getting backed up causing the cutters to pause for a bit

solar moat
buoyant tundra
#

Cutters produce two outputs and if one of them is lagging behind both will be delayed 😅

#

It's the same with swappers, but cutters are a more frequent culprit from what I've seen

#

If you want to share your save, I can investigate as well when I get the chance in a bit

¹ Visible gaps in output, but strangely displaying 100% utilization on that same belt.
² Visible gaps in upper input and output. Hitches/blocks in lower input, which is to be expected with the gaps in the upper input.
Version 0.0.8.

Gaps in Output. Now with 99% utilizaton.

#

Gaps in Input.

#

Maybe it's a fluid pipe throughput issue?

#

Switching over to a different painter design to see if that helps. 🤔

buoyant tundra
#

As of right now, pipes have infinite throughput though that will change in the future to be the listed 7200 L/m

solar moat
#

Switching to the different painter design may have helped. 🤔 Playing around with different testing methods to see if I can get the problem to reappear with the new design.

buoyant tundra
#

This may be the offscreen painter simulation accuracy thing that's been brought up once or twice, but also I'm not entirely sure

#

Either way you can make this factory better with the bent stacker and swappers

solar moat
#

Hrm, how do I get the bot to do the fancy stuff it does with previews for blueprints? Or does that not work in 0.0.8 builds yet?

buoyant tundra
#

I'm genuinely not sure what the problem is here

solar moat
buoyant tundra
#

Bent stackers are faster and smaller and check the top pin in #💬shapez-2 😅

buoyant tundra
#

Yes, swappers are amazing for making checkerboards like your current goal needs

solar moat
buoyant tundra
#

Both can improve your factory

#

You're doing a lot of stacking with six straight stackers, but you can do the same with only four bent stackers in a smaller area 😅

solar moat
#

Ah.

#

Well... hell.

buoyant tundra
#

The upgrade was only updated to say that it's faster in 0.0.8, so it's perfectly understandable

solar moat
#

But... can you shrink down from a 1x2 to a 1x1 with bent stackers?

buoyant tundra
#

As of now, only if you ignore that collisions will be coming in a future update 😅

solar moat
#

Collisions?

lost yarrow
#

It's possible but there hasn't been a design I would consider super usable right now

#

Launchers making shapes phase through anything is a bug

#

It's planned to be patched

buoyant tundra
#

Eventually shapes thrown from a belt launcher will collide with buildings/lifts and not make it through to the catcher

solar moat
#

And how do I mark this post/question/thread/forum-thingy resolved? The different painter design seems to only result in occasional visual gaps in belts when changing zoom levels or first viewing an area, but utilization seems to be 100%.

buoyant tundra
#

I have in fact not figured out how to set tags on threads

Cheaper blueprint cost plus I don't think you can make a 24-12 blueprint on a 1x2 with straight stackers

buoyant tundra
#

I must not have permissions for that then

solar moat
#

Maybe only OP.

Layer = shapes

#

Floor = factory

#

Now make a 36-12 double stacker in a 1x2 without bent Heh

#

(it's been done with bent)

#

Stackers have a gap in the middle so it's possible it won't break even with collisions

#

But yeah still not ideal

#

It would be cool if whether a launcher collided with a stacker was timing dependant (as in it only collides if a shape comes through the top of the stacker at the same time as one launched through the side), that way you could still make a design like that work, but it would have to use wires to make sure the timing synced up to alternate between the launchers and stackers

solar moat
#

Argh. I have to unmark this one as resolved, because I'm discovering gaps again. 😬 Same spot.

#

Or maybe not exactly the same spot. Input on the stacker, yes. Output on the painter... not so much?

#

Which is weird, because the painter only feeds the stacker.

#

If anyone wants to take a look. I've made no progress in making shapes in an hour and I probably should. 😅

lost yarrow

it just be like that sometimes
