Hi, Thanks for the update.

I was also thinking about threaded rods for the Z-movement. Printing gears with some error increase gigantically with perspective to the printing accuracy. I have seen your dropbox photo's and I have to say that you have nice workarounds for multiple issues.

And from your point of view, would it be beneficial to make this 3D printer to save money instead of just buying a RepRap and might I ask how much money you spend to this point or would you suggest of buying one?

Cheers.
