I've not played much with Minefactory Reloaded until recently. I've been checking out the machines like the chronotyper, which allows you to split baby animals away from the herd, then when they grow up, you can pull the now adults into a chamber with a grinder and convert them into products plus monster essence.

Monster essence is useful for both the auto-spawner and the auto-enchanter. To use the auto-spawner, catch a mob in a safari net, and place the net in the auto-spawner, supply monster essence and power, and watch your mobs spawn. It takes many kills to make enough monster essence to spawn a mob, so you normally have to kill quite a few cows, pigs, and chickens before you have enough to spawn mobs from the safari net.

An auto-spawner with a full supply of essence will spawn about a dozen (actually, I'm making this up, but it's not a lot) mobs, give the drops, and generates a bit of essence from the kills, and then is done. So you have to keep adding mobs for the grinder to kill to get more monster essence. What happens though if you use a mob then generates more of itself when killed? What about magma slimes or slimes? I believe there are 4 or 5 different sizes of slimes that can be spawned. Each time a slime is killed, it "splits" into several (1-4) of the next smaller size. If you spawn one of the largest slimes, one spawn can turn into as many as 64 more.

I found this out the hard way as I put a magma slime in the auto-spawner (I wanted a handful of magma creams.), and ended up with a never ending tide of magma slimes. By the time I figured out the spawns weren't going to stop on their own, and made it around to the maintenance tunnels below to remove the safari net from under the machine, I had 6 stacks of magma creams. (I was killing the slimes with my sword along with the grinder killing them as well.)

So, how to turn this information into a endless supply of mobs of your choice? Simple. Have a grinder send monster essence into the bottom of a small xycraft tank. (I'm using a 3x3x5--3 air spaces) have a valve block on the lowest level feeding the auto-spawner (with slimes). On a higher level have a tube that feeds monster essence to another auto-spawner. This way the auto-spawner creating the slimes always has enough monster essence to maintain it spawning mobs to grind. Extra essence will flow through the next level valve once enough is stock-piled in the tank. Feed this essence into another auto-spawner with the mob (in safari net) of your choice. Depending on how much monster essence is created, you may have enough left over to feed an additional spawner or an auto-enchanting machine.

The only question now is what do you do with stacks and stacks of magma cream and slimeballs?

*edit - make sure to update MFR to 2.3 as the 2.2 version with Ultimate 1.0.1 is bugged and the auto-spawner doesn't work right.

To fill in some missing facts.

All mobs killed by a grinder generate 100 mob essence.

Auto spawners in the default mode use 150 mob essence to spawn a mob. They are spawned one at a time -- if it has enough essense in it's tank the auto-spawner will spawn them rapidly. It has an idle bar like all MFR machines, so it has built in delays when no work can be done.

I am not 100% on this, but believe Auto spawners have the default vanilla spawn radius (8x8 - extra block on the N and W sides).

You only need one chronotyper. The grinder will only kill adults, so have a breeding room with the chronotyper in it. Send the babies to a grinder, when they grow they will be killed in short order.

Slime type mobs are very good essence generators. They will spawn as one of the 3 types, so 2/3 of the time you can expect more essence back than it cost to make.

I don't bother with storing essence. I use tesseracts at grinders and spawner and everyone shares... I just have some feeder grinder cells that kill passives to restart the slime loop if there is ever a shortage. Think i have one pink slime spawner feeding 2-3 witch spawners.

I have a system like this, though it isn't completely independent of soul shards. I use a cow soul shard to supply the monster essence that the auto-spawner uses in creating mobs.

I do, however, feel much better about using this system instead of a full collection of soul shards. Soul shards always seemed a little meh... or at least, when it comes to mobs like Endermen.

Also, my spawner actually uses 500 mb of essence to spawn a cow.

The tank is mainly there to keep the essence generator going. Only surplus essence goes to feed the the secondary spawners/enchanter.

Thanks for the chronotyper info. Should make it a bit easier to manage it all.

I've never done much with MFR but this seems really cool and not quite as cheaty as Soul Shards. You've just encouraged me to go try this mod out :) To the Test World!

I wanted to use Conveyor belts for something practical, so I did this for my grinder.

So, what's the answer to my final question? What do you do with all the magma cream and/or slimeballs?

You can turn slimeballs into rubber, I believe.

That's always nice to have.
