Greetings from the far side of the pond. I encountered this thread via Google search, while looking for any kind of discussion related to the SX2.7. It seems to have not quite caught on as strongly as either the smaller mills, nor the larger X3. Thank you for posting your experiences with it here. I'll be following with interest.

What kind of modifications did you have to make to your ballscrews and/or the mill itself to get it adapted? Or, did you miraculously find some stock part that fit like a glass slipper?

Thanks again for sharing info!
