Machines can be chunkloaded only when they have recipes to process, to save TPS.
We need only a little redstone, a World Anchor, and 2 Blood Magic teleposers.
In the center chunk of a 3x3 chunk area with your machines inside, place a Teleposer and click an Enhanced Teleposition Focus on it (the 3x3x3 one). Don't load these chunks.
Place a Redstone Block and a World Anchor within the area of another Teleposer, and put the Enhanced Teleposition Focus in.
the below should be placed OUTSIDE of the Teleposer's 3x3x3 area
Place an XOR gate, with this Redstone Block as one of its inputs.
Place a State Cell as the other input. The input to this State Cell will toggle when the machines are loaded.
Attach a timer to the XOR gate's output, and connect the Timer's output to the Teleposer.
Put a hopper or something to supply the World Anchor with Chunkloader Coins.
