I was looking at the detailed construction of the MK2 and wondered why they decided to have the lead screws exposed to the work area. It seems they could have them facing out where they would be less exposed to the dust and shavings in the work area, similar to the openbuilds type construction. It would have made the gantry jut slightly wider I think but just barely. Was it for safety to have the moving parts face in as opposed to out?
Just curious.
