I don't think .01 is very far out of reach. You can feel a lot less with your fingers.
I believe I read that EMC can do leadscrew mapping, but I'm not sure. You might want to look into it, if you're concerned. But I think a lot of homebuilt machines can get within .01. If you have no backlash, then you should be pretty consistent.
