I installed an Extruder MK2 Module into a router in the latest 1.12.2 version and latest Forge version and put a template in. It would extend, but when power was removed, it stayed open. Am I doing something wrong?

Would need to set your setup since the router is probably still getting powered from somewhere. Bear in mind though that the 1.12.2 I version is out of support these days so I won't be making any code changes.

It was just a Extruder MK2 extruding 9 dirt blocks upwards, with a lever on the side.

Is there a setting I have to turn on to make it break blocks?

Closed due to lack of response. Also, I don't support 1.12.2 any more, sorry.
