That's a long memory. I've now had umpteen ideas for this, so I'm not sure which particular one I was talking about in that thread.

But for the record, I'm thinking of trying what zee is doing on his build, I saw the idea on some US CNC parts site. If anyone has tried that technique with the tramming plate I'd be most interested to hear how well it works. I'm starting to toy with the idea of building a new frame and gantry for my machine (which was the basis of the idea in this thread), which I'd probably incorporate it into.
