Gregtech 1.7.10 Issues with EBF

Could you provide a picture of the top of your EBF? I think using a heat proof machine casing in place of the muffler hatch, or having the muffler hatch pointed the wrong way, could produce the effect you describe, without showing up as an error on the console.

You need also a fluid input hatch in the bottom row with oxygen to create steel from wroug iron. Also you may not provide enough amperage to keep the EBF running. in LV yopu need 3 amps to get to the 96 EU/t needed, but depending on your exact setup you may need more than 3 Amps to be produced/stored for the EBF to run.

give that a look and see if it helps, I also have videos for most other multiblocks in GT5U

If the OP didn't have a fluid hatch with oxygen, it wouldn't have started processing the wrought iron. Also, wrought iron to steel takes 120 EU/t, not 96.

However, I looked more carefully at the second screen shot the OP attached, and the output dot of the battery buffer is visible with nothing connected to it. The cables are connected to the input sides of the battery buffer, so none of the power is getting to the EBF. Unlike single-block machines that iirc won't even start processing with an empty internal energy buffer, GT multiblocks will attempt to start and immediately destroy the processed material (I found this out the hard way once with an implosion compressor).
