I tried to craft basic circuit by importing basic circuit board and NAND chip into assembling machine using gregtech item pipe. However, either basic circuit board or NAND chip got stuck inside the item pipe, just like the assembling machine have only one available slot. For example, if basic circuit board occupied the 1st slot, NAND chip cannot be imported into 2nd slot. I also tried with robot arm, still not able to insert into 2nd slot. But when I tried crafting NAND chip with the same setup, it works perfectly fine, both red alloy wire and iron item casing can insert into the machine. So I am not sure what cause the problem. Do someone know how to fix it?
