hello there,
we use MC 1.10.2 and the latest TechReborn (1.4.7.70) on our server.

the Rolling machine does... nothing... it looks like it doesnt even get power.

According to TheOneProbe, it looks like the rolling machine gets power, however, the indicator in the gui doesn't show that it does.

The issue here is the recipe:
.addRollingOreMachinceRecipe(ItemParts.getPartByName("cupronickelHeatingCoil"), "NCN", "C C", "NCN", 'N', "ingotCupronickel", 'C', "ingotCopper");

But as seen in the linked image below, only ingotCopper shows up; we do not have ingotCupronickel. I'm not sure if this is intended: http://i.imgur.com/ab93j5C.png?1

Also, and this is a separate issue, it doesn't look like modTweaker has a handler for techreborn.rollingMachine.addRecipe. I was going to add a workaround for the coil but this is one of the new machines that doesn't work with MT.

Oh that's strange O_o

Ok, so it sounds like the gui isnt showing the power
and the recipe needs to be using copper for everything
and it needs minetweaker support.
