factorio latest 2.0 version

Hey,
made a lot of stations working just fine, and when trying to use a requester station with sand from the K2SE mod it just won't recognise the item. I don't know if its a LTN problem or K2SE problem tho

Well I tried the mod : LTN combinator modernized, and it works now. The vanilla combinator doesn't seem to work with the sand only, other items work just fine. I used the LTN manager mod and it shows I have sand in my stations but no trains go there, if I switch to ask for quartz or smth else from the K2 mod it works. I don't know if I should address this issue here or in K2 mod.

Is it possible the original setup was just incorrect? One thing that is really nice about the LTN combinators is that it is harder (not impossible, but harder) to mess up the signal you are feeding into LTN.

I think I made a mistake, something about the threshold and the number of items requested. Maybe because the stack is at 200?
When I put 80 stacks and request -8000, it doesn't work, but if I request -16000, it works. So I think it's because 80 x 200 = 16000. I can't bring in a train because I'm requesting less than 1 train (my trains have 2 cargoes, so 40 x 2 stacks).
Sorry for reporting a bug when it was a misunderstanding on my part.

no worries. Glad you figure this out.
