Hm, it seems that I never actually added compatibility with IR2 for this mod or Mini Machines... I've copied over the band-aid patch from Mini Machines, which will prevent the load error, and allow the game to load up with both mods, but there won't be micro assemblers, miners, or furnaces.
For now, this means only micro radar and micro beacon will exist when loading with IR2 (as of v2.0.4).
I'm currently working on a rewrite for one of my other mods, so I won't be able to add in fully featured compatibility until later. Hopefully, being able to load into the game is better than nothing, and micro beacons at least, are one of the stronger micro machines.
