When configuring the digital miner with an ore dictionary filter, the text field you use to input oredict entires is not large enough for some ores. Pig Iron ore ("oreNetherSteel") added by the Nether Ores mod is an example of one such ore, as seen in this screenshot:

is that the only oreNetherS or are there others?

Alright, sorry for bothering! :D

Just do oreNetherSt* :)
