Some people on Sevtech needed help with their chamber, so I'm making this guide! Step 1: Construction. The edges of the chamber, 3x3x3 or 5x5x5 need to be made out of "Pressure Chamber Wall" Like this: The sides of the chamber need to be filled in with "Wall" or "Glass" with 2 "Interface" and 1 "Valve" The finished chamber (5x5x5) will look like this: The valve is on the center block of the right side. Make sure that one of the interfaces has the "O" facing the INSIDE of the chamber, and the other has the "O" facing the OUTSIDE of the chamber. There are 3 GUI elements to the chamber, the chamber itself, and the 2 interfaces. The chamber: And the interfaces: Step 2: Input You will be inputting pressure and items. Pressure goes in using pressure tubes and air compressors: The best way to input items is with a chest and an omnidirectional hopper: Step 3: Output You will NEED to PULL items out of the output interface. Also make sure you set the filter so that items stay in the chamber to get crafted: You can remove the filter after the items have crafted, and they will be ejected into the interface. Once there, use whatever you want to Pull the items from the interface and into storage. And that's it. Any questions just leave a comment!
