Factorio ltn request stack threshold No more mostly empty trains when requesting/providing ores. LTN needs paired provide/request stations to generate a schedule. My suggestion for LTN noobs is to set the stack threshold to the number of stacks your train can carry, and the request to 2x that number. Meeting the item threshold, but not the stack… Adds logistic-train-stops acting as anchor points for building a fully automated, train logistic network. - Someone looking to better understand Requester Threshold / Output Signals and the calculations behind thresholds. The fact that the sign ($+$ or $-$) of the signal is what controls station behavior leads to a common pitfall where an unfamiliar user might find that their requester stop has unintentionally become a provider. I How to set up a basic LTN system with provider, requester and depot stations. Meeting the item threshold, but not the stack… Nov 30, 2018 · I'd love to be able to specify a provide/request threshold as stacks as an alternative to number of items. Requesting a single full car of iron plate would be 4000 or 40 stacks at 100. When using this mod to build my last megabase, I found myself constantly setting certain values to the same values, particularly Limit Trains, Provide Stack Threshold, and Request Stack Threshold. These stations play the same roles as "provider chest, " "requester chest" and "roboport" in vanilla factorio. It may leave items in inserter arms but unless you use mixed stations it doesn't matter at all. To my understanding, the large request number means the signal will always be negative, triggering a request. Nov 10, 2024 · Sets value of "Request threshold" virtual signal from Request (or stack) threshold of LTN combinator if station is requester Sets value of "Locked slots" virtual signal from Locked slots of LTN combinator Jul 20, 2017 · Request Stack Threshold (optional) - Missing amount of item stacks triggering a delivery. Many people put different size trains on different networks but the above should be good, assuming your smaller stations are In a system with the default item threshold of 1000, and a stack threshold of 2: Requesting 2000 space science. Meeting the item threshold, but not the stack… Mar 17, 2023 · LTN troubleshooting by zOldBulldog » Fri Mar 17, 2023 10:15 pm Hoping that someone can give me hints for how to troubleshoot the following. My station designs, when used with wide chests and loaders, can also work with any amount of items. This tutorial runs through how to wire the stations up and what signals to set Mar 31, 2023 · LTN offers the ability to use stack thresholds instead for increased flexibility, although fluids must use the regular threshold signal. A typical value is two full train loads, so that together with the request threshold (see below) of one train load, the station calls for a new delivery once it contains less than one. Aug 1, 2018 · I don't know how often LTN scans the stops to create deliveries, but I'm going to assume for the purposes of this idea that it happens once a second. My question is to help my understanding of how the Request Threshold works. There are three types of stations, each of which I'll describe in this guide. I am currently using it on a new outpost-oriented base with a goal of 5KSPM. Green-wire all the chests (and power poles where needed) to the LTN combinator. I thought of using stack thresholds, but it's unclear how that works with liquids Is there a way to set a separate request or provider threshold per item / liquid at a single logistic train stop? Sep 11, 2017 · Like instead of setting a request threshold, I'd like to set a request train slot threshold. Once that -400 is larger than the request threshold it will make the request. Community-run subreddit for the game Factorio made by Wube Software. The threshold is the amount of missing material needed before a station is marked as a requestor and 4000 iron is only 40 stacks. The provide threshold just says "Ignore me if I have less than the threshold" So if you have a provide threshold of 10,000 and 5,000 plates then LTN will pretend the station doesn't exist, even if there's a requestor with a request threshold of 2,000 and a request of 4,000. (default=0 false) Provider: Provide Threshold (optional) - Amount of items/fluids Apr 26, 2020 · To LTN it makes no difference if a station provides/requests 1 or 100 items as long as the station buffer can hold enough items. 2L-4C trains have 4 * 40 = 160 stacks of cargo inventory. LTN completely ignores stack thresholds for fluids and only uses the non-stack thresholds. If you set both the "request threshold" and "stack request threshold", the regular threshold is ignored for items but not for fluids, so fluids use that request threshold, while the stack threshold is used for items. Request Priority (optional) - higher priority will be served first (default=0) Disable Warnings (optional) - Suppresses warnings, like no station supplying x found, for this Requester. Aug 1, 2018 · Feature Request: Relative Request Threshold Signal by jaakon » Wed Aug 01, 2018 8:47 am Can we get an additional "Request Threshold" Signal, which sets the amount of missing items in percent? If we have a station requesting different items in vastly different quantities, it's always a problem (at least for me?) to set the correct threshold amount. The exceptions are when you have items of different stack sizes, in which case I generally set the threshold to the smaller stack material, but you really only run into that exception when you're using bot-based multi-purpose unloading stations. Since I've started installing LTN trains into my networks, I've greatly increased the efficiency of my rail networks and allowed everything to run better. Nov 30, 2018 · I'd love to be able to specify a provide/request threshold as stacks as an alternative to number of items. So if your providers aren't circuit controlled then you will get way oversized deliveries. Set the Request Stack Threshold in the LTN The request threshold signal sets the request threshold "per-station" whereas the station control combinator can set or override the threshold per-cargo as well. A request threshold of 80 stacks will never be met by a 4000 iron request. Which is great, because in a mixed item/fluid station you can independently use the stack threshold to control solid items (stack threshold if set always has precedence over item threshold) and the non-stack threshold for fluids. You *have* to put in a negative request threshold or it doesn't work. Since I was using 1-2 trains without stackers, I was constantly setting these fields to 1, 80, and 80 respectively. (default=0 false) Provider: Provide Threshold (optional) - Amount of items/fluids 373K subscribers in the factorio community. For this example, I'm going to use three groups, "high demand" (request threshold 10000), "medium demand" (request threshold 1000), and "low demand" (request threshold The request signal is -160k (double the chest storage capacity), the request stack threshold is 160, and max trains is 2. This value can be overridden by sending virtual signals into a Station input. Feb 7, 2022 · Re: Best Way to Debug Issue by robot256 » Wed Feb 09, 2022 10:13 pm Normally Request Threshold is set to the size of a single train, to ensure you only schedule a train when it has space to unload. Use stack thresholds to service different stack sizes efficiently from one station. Using the stack threshold on the station is easiest for this. Meeting the item threshold, but not the stack… The request threshold is based on just the count being sent to the station - so typically you would have a combinator sending (-1000) to request 1000, and the chest inventory sending (+600) for what is already there, resulting in (-400) being actually requested. Place 6 steel chests alongside where the wagon will go, with inserters on each side, to unload the wagon and then the chests. In the graph Nov 30, 2018 · I've successfully broken LTN code into more manageable modules, made the interface more in line with normal factorio data models and, what most in this thread want to hear, added stack provide threshold and stack request threshold signals. Thanks for your consideration and creating LTN! Gullyn ps. I'm about to turn on at 1. Sep 11, 2017 · It's fun to go somewhere, put down an LTN station and request: 1000 belts, 50 undergorund belts, 20 splitter, 20 stack inserters, 50 inserters, 20 asembler, 10 signals, 5 chain signals, 500 rails, . So if I had 10 cargo wagons on my trains, I'd set that signal to 10 * 40 = 400, and LTN would never send a partial train. For this example, I'm going to use three groups, "high demand" (request threshold 10000), "medium demand" (request threshold 1000), and "low demand" (request threshold Jul 20, 2017 · Request Stack Threshold (optional) - Missing amount of item stacks triggering a delivery. Or maybe there is an obvious mistake that you can mention. For this example, I'm going to use three groups, "high demand" (request threshold 10000), "medium demand" (request threshold 1000), and "low demand" (request threshold . Jul 20, 2017 · setting request threshold, limit train size, asf per stop is generally a good idea for networks with multiple items When a train arrives the expected train inventory is sent from the output alongside the train composition. In a system with the default item threshold of 1000, and a stack threshold of 2: Requesting 2000 space science. So for 8 wagons you set the threshold to 8x40, ie 320. Meeting the item threshold, but not the stack… Set the "provide stack threshold" on the provider to the size of the largest train you would like to use (number of wagons * 40 for vanilla trains). Once the difference between on hand and requested items exceeds the negative value of the request threshold a train will be scheduled. At each requester stop, put the cargos into an appropriate number of groups. What, then, does the stack threshold do in this case? In a system with the default item threshold of 1000, and a stack threshold of 2: Requesting 2000 space science. Blue circuits: 1,200, threshold 600 (200 per stack) (In this situation, the stack size vs required amount is completely backwards) each of these is presented to the LTN station for 3-4 seconds at a time, then its the next item's turn. Then LTN will respect the actual request amounts and leave stations the moment the wagons contain wanted amount. Do the same for requester stations and "request stack threshold". This makes the network ignore positive quantities unless they're above this number. Specifically for each: a provide threshold is the amount of an item that is needed before that station will appear in a schedule as a pickup location, and a request threshold is the amount of a requested Aug 19, 2023 · Who is this guide for? - Someone searching for using the LTN Modernized Combinator correctly. 8) Regarding this, usually when I'm dealing with items with wildly different stack sizes, I will just set the threshold to 1 and then "lie to LTN" by only sending the signal for each item at all when it has reached its individual threshold. 13 This station can handle multiple items and will only unload items scheduled to unload. Meeting the item threshold, but not the stack… Jul 23, 2022 · Re: Threshold and Stack Threshold by Litcube » Sat Jul 23, 2022 4:06 pm I don't understand the point of stack thresholds and request thresholds when it comes to a requester station. So, let's begin. (default=0 false) Provider: Provide Threshold (optional) - Amount of items/fluids Stack threshold is ignored for fluids, so you are ending up with the default request threshold (which is 1k if you don't change it in the mod settings). 10. Meeting the item threshold, but not the stack… In a system with the default item threshold of 1000, and a stack threshold of 2: Requesting 2000 space science. (default=0 false) Provider: Provide Threshold (optional) - Amount of items/fluids Aug 1, 2018 · I don't know how often LTN scans the stops to create deliveries, but I'm going to assume for the purposes of this idea that it happens once a second. Sets value of "Request threshold" virtual signal from Request (or stack) threshold of LTN combinator if station is requester Sets value of "Locked slots" virtual signal from Locked slots of LTN combinator Nov 30, 2018 · I'd love to be able to specify a provide/request threshold as stacks as an alternative to number of items. I'd love to be able to specify a provide/request threshold as stacks as an alternative to number of items. Meeting the item threshold, but not the stack… Jan 26, 2021 · Add a high provider threshold (or provider stack threshold). Requester v2 for LTN 1. Oct 19, 2024 · Requester stop Place an LTN Combinator near the Input (Lamp) and connect them with a green wire. Aug 3, 2020 · In a system with the default item threshold of 1000, and a stack threshold of 2: Requesting 2000 space science. Meeting the item threshold, but not the stack… Feature request: is it possible to make global mod setting for default stack threshold instead of default item threshold? Or even better, if the default (stack) theshold could be set to full train capacity, so by default only ever move full trains of cargo, and whoever wherever needs something different can set circuit signals accordingly. I could set a "provide stack threshold" as 50 which would work for barrels and ores. Set the LTN Combinator to Requester mode. For this example, I'm going to use three groups, "high demand" (request threshold 10000), "medium demand" (request threshold 1000), and "low demand" (request threshold Finally, put two combinators as before, but multiply by 8000 instead of -8000, change "Request Stack Threshold" to "Provide Stack Threshold" in the constant combinator and rename the station as you wish. Thresholds are the limit at which point the station will be considered a provider or a requestor, otherwise a default threshold of 1000 will be set for that item (or whatever you set it to). Red also reads the chests’ contents. Default Request Threshold (ltn-dispatcher-requester-threshold) - integer 1 - max, default is 1000 The minimum number of items to request before LTN creates a delivery. ) It never even occurred to me to set it negative. Takes priority over Request Threshold. Request thresholds are denoted by a positive number. Mar 27, 2019 · If I set the request threshold to 16k, coal will never be delivered, but if I set it to 8k, whenever iron is needed, LTN is creating 2 8k requests to the Iron plate factory, but the first train will empty it out, leaving the 2nd train just a waste of time. (Stack Request Threshold is even more useful for this. On station combinators there is a setting called "Stack thresholds". The default is 1000. Jul 20, 2017 · Request Threshold (optional) - Missing amount of items/fluids triggering a delivery. Jul 20, 2017 · Request Stack Threshold (optional) - Missing amount of item stacks triggering a delivery. LTN should probably treat negative numbers Adds logistic-train-stops acting as anchor points for building a fully automated, train logistic network. For this example, I'm going to use three groups, "high demand" (request threshold 10000), "medium demand" (request threshold 1000), and "low demand" (request threshold Aug 1, 2018 · I don't know how often LTN scans the stops to create deliveries, but I'm going to assume for the purposes of this idea that it happens once a second. I think one of the reasons LTN has two separate signals is for stations that request both fluids and items, since, like you said, you can't set request thresholds per item. Sep 9, 2019 · First, I love using LTN. Meeting the item threshold, but not the stack… If small trains (eg 1 wagon) are going to stations expecting larger trains you need to set the request threshold higher. - Someone who is struggling to setup their first LTN. 8K and work to increase. Only applies to non liquids. (global default=1000) Request Stack Threshold (optional) - Missing amount of item stacks triggering a delivery. I have a simple setup (or supposed to be): - Stations always load and empty a full train. The request amount is the negative number of how much of each item you’d like to have in the stop. Meeting the item threshold, but not the stack… Nov 10, 2024 · Sets value of "Request threshold" virtual signal from Request (or stack) threshold of LTN combinator if station is requester Sets value of "Locked slots" virtual signal from Locked slots of LTN combinator In a system with the default item threshold of 1000, and a stack threshold of 2: Requesting 2000 space science.
