Umm no. I do same thing, no modloadermp and it says machine block has id 260 but buildcraft block want id. in all fairness since I had buildcraft first I tried to look for the ids in industrialcraft but can't find it. I stopped trying the redpower part but no success. I also looked for id's in buildcraft but could not find a single number thingy that said 260. That buildcraft part about no finding ids is not your problem but I just have to say you need make ids configurable. Also don't blame my installation powers. I've been doing it since 1.5_01 (the mods not minecraft) Please help me out I want to do some industrialcrafting again.
