Nope, that it a smoke particle from what I can tell...Looks like a little derp on your part, from this angle it looks like the hopper is feeding into the back wall of cobble. When you place it down, the face you highlight is the one the hopper will feed into, you can change the bottom pointer with a crescent wrench or break the block and reorient it manually.
You sure those are crucibles and not stone barrels =D?No, it's not. I explicitly tried it on all four sides of a single crucible and none worked.
*sigh* They're crucibles. They're fired. I know how to read. They're just not putting any items into them from hoppers, from any position. Ducts don't work but I already read why they don't, so I tried their "fix"...which also doesn't work.
In my LAN world with my friend, I already have the diamonds and emeralds necessary. Its not terribly difficult if you, like me, sift stacks of gravel at a time, then use the activator to get more stuff. I almost find it less annoying to hunt for diamonds in AS then in vanilla, mostly due to the fact that when I get diamonds, its because when I do, i'm not hunting diamonds, i'm sifting for ores. So when I do get a diamond, I often don't even notice it until i'm sorting my inventory into my chests.And how do you get the emeralds and diamonds for the automous activator you need to get past the all but impossible to obtain diamonds and emeralds via the rule of large numbers? Because just getting a pulverizer is useless if you can't get enough diamonds and emeralds to back it up. And your options boil down to getting villagers via a handful emeralds and blood magic, or the Autonomous Activator.
Come to think of it, a LOT of machines in TE3 have punny names because they often have added alliterative appeal.
Even better, use slabs first. You can reorient them using the crescent hammer when you're able to make enough torches.Also, soon as you get an Igneous Extruder, use the ridiculous amounts of cobblestone you will generate to build a large expansion to your platform. It will give you a lot of room to expand. Don't forget to light it up. I've already used said expansion to build my smeltery, a furnace wall, and a high-output sugar cane farm.
I'm not using item ducts as I said, since they're not working properly, only using hoppers. And all five sides really, including top, with cobblestone.Okay, next question, what is it you're trying to feed into them?
And, from this comment - "No, it's not. I explicitly tried it on all four sides of a single crucible and none worked", it's not clear if you tried shift-clicking the hopper directly onto the top of your crucibles which is the usual configuration that's worked fine for me.
Are you also feeding the crucibles through the item ducts? And if so, what are you trying to insert?
Another tip for the MAC is that you don't have to fill the inside for it to work. If you only have a couple of diamonds or are short on redstone, you can just make a single pattern provider and put it in. Any size MAC automatically gives you one CPU's worth of crafting, so all you need are patterns to use it. That means if you build a 7x7x7 cube but can't fill it, just put a pattern provider inside against one wall. Make more stuff later.As has already been answered, nope. I generally keep one of the dimensions of mine small (2x2 inside, 4x4 outside) so if I need more storage room/CPUs, I don't need to make ton of them.
Just another general troubleshooting:I'm not using item ducts as I said, since they're not working properly, only using hoppers. And all five sides really, including top, with cobblestone.
