I want to suggest Assembler can use Engineer's Hammer to increase one or two Output port on both sides of the machine because some synthetic formula like obsidian need to barreled magma and water but the machine even if connected pipe to transmission water and lava in to the machine but the machine didn't work so I hope can make machine to make obsidian

You can easily pipe in both liquids through the same pipe. IE's pipes are perfectly capable of this.

Provide version info and pictures of the assembler's GUI.
Please follow the contribution guidelines next time, so that your issue is more apparent.

That is, both liquids are already in the machine but cannot be synthesized. This is my problem.

I use ImmersiveEngineering-0.12-81

Works fine for me on IE 84. Please make sure to use the latest version when reporting issues.
