I followed the book to build this chamber, after finish build i connected it to power cable, output to chest, and input connect to the controller, the item also passed into controller, but the machine is not working, also no gui showing.

Is there any info why this issue was closed? It may benefit other people who stumble on a similar problem

I think the issue is that they were trying to use the controller to input items while they needed to use the item input block below.

No, Is because when I use the book to build, and the controller at the transparent template not facing outside, instead if facing at 3 other side. When building it, the controller face outside wont show complete.

It's called input for a reason
