Stopping EU going through cables

[Sonicyoda13]

Is there a way I can have my matterfabricater hooked up to the end of my cable but it only uses energy that's leftover from other machines but not drain from my storage device

As far as I know, nope.

EU Storage devices can be set to emit a redstone signal only when full. An EU Splitter cable will only allow power (under 512 EU/packet) to pass when it has no redstone signal.

One detail about how EU distribution works for multiple machines (EU storage blocks are machines in this context) asking for it on a same cable is that the power gets evenly distributed regardless of if something could use more. But of course if something doesn't use that much it frees it to be split between the other machines. But what I'm getting at is that what I did with my Matter Fabricator initially was that I simply had it parallel with storage devices so it could only take half of my power if I used it for something. But if the storage was full Matter Fabricator would take all the generated power. Didn't need to configure anything else about it. If you're making UUM you should be able to afford half of your power going into that especially if you have big storage for machines to use.

As a way of toggling the cable, you can have a turtle break/replace it when it receives a redstone signal or use a sticky piston to toggle whether EU runs through or not. By having your energy storage run EU into the machines for about 1200 ticks (1 minute) you could have it toggle the turtle/piston after that minute for 100 ticks (5 seconds) to let the excess power flow into your mass fab. And have it cycle back to the EU going into the machines again afterwards. You could even shorten the second time to about 2 or 3 seconds, to decrease down-time with machines and increase processing speed (as well as induction furnace efficiency).

if sense == 0, do
    print("For 1 minute, EU flows into your machines and your mass fabricator
    won't be running because it's not getting any EU. After that minute passes,
    your machines will shut off and your mass fabricator will be able to receive
    power for about 5 seconds. All excess EU that's floating in the cables will
    flow into your mass fabricator. After those 5 seconds pass, your machines
    will turn on again and your mass fabricator will be disabled")
    end
end

You're over thinking this. An Engineer using the right tool for the job. Get a Redstone Control Panel for your Matter Fabricator. You don't need to run it 24/7, so with redstone control you can make it run when you want it to.

Or, y'know, separate it from your main EU grid and only give it power from certain sources. But Redstone Control is my choice.
