Hi, I'm still trying to figure out why it's not working for me, but I wanted to report that when I set the combiner to Require Material I expected the icon to be the one not colored red, whereas when I'm material provider the icon that appears in Alt mode is the one colored red. It seems that the configuration is reversed.
As for operation, I add LTN stop, connect the combiner to the lamp and set requester or provider, in output I enter the quantity and material, but nothing happens. Obviously somewhere else in the map is its counterpart, i.e. I have a requester and a provider. I have also connected the network to a checkout but nothing.
Thanks in advance for your help

@momift,

I'm sorry. I'm not really understanding what you mean. None of the signals have a color. At least not related to the combinator. Requests are negative (-) numbers, and Provides are positive numbers. This mod (LTN Combinator Modernized) is essentially a GUI on top of a constant combinator that helps build and set the appropriate Logistic Train Network signals. What the signals mean and how to use Logistic Train Network remains as documented in that mod. How to use and configure the signals for Logistic Train Network can be found here (https://forums.factorio.com/viewtopic.php?f=214&t=51072).

If I am pointing you in the wrong direction maybe you can explain what is happening another way. Maybe provide a screen shot and / or a save file that is demonstrating the issue you are seeing.

I'm having the same issue as this person. When you set it to provider the signal it puts out is the "request if item is less than" signal is output from the combinator. And vis versa. But it's weird, because I've got some stops set up and they work fine. But new ones I build have this issue. If I tinker with it long enough, I can get it to do what I want. But have to turn both on and off and back and forth and turn the whole thing on and off a few times. If I recreate the actual desired signals the LTN mod works as expected. But using the LTN combinator on new stops it has issues.

Do you have some screen shots showing what it is doing, along with an explanation what you think it should be doing? Provide a save file with the issue reproduced. Make sure that after saving and reloading the file it is showing the undesired behavior.
