For take all mods and configs, use serversync and host espin.pro

looks like an elaborated modpack, does it have altered recipes (seeing crafttweaker there means probably the recipes have been messed with)

maybe the pack-maker simply removed it by accident or forgot to put it back

oh. okay. Thanks a lot! I will try to add a new one and will see

UPD. But seems it`s not a modpack issue. No any changes in crafttweaker for immersive.
Also, I found this post:

I guess some mods can affect this behavior...

No, this is most likely related to existing assembler issues, which malte has fixed. The next release should fix this.

sure, if modpacks change items and recipes after a certain point or way (meaning no how it is meant to be done) immersive engineering can not adapt and you may have to add the recipe back yourself ... but i just noticed in the video, that the recipe seems to be detected properly but is not executed properly ... is this a client on server situation or pure singleplayer?

or Blu is faster in typing and overthrows my answer with an fixed but not released yet version :D
