Project #21, Donkey Kong X Axis

The UK maker faire is fast approaching so I thought I better get started on the Donkey Kong remake. This week I mostly concentrated on redrawing everything (as I appear to have lost some original files) and getting some of the parts moving. This is the X axis that will support Mario and he moves from left to right. It's a very simple stepper motor and belt drive combo. I made custom brackets at either end for my parts and affixed them to some 8mm rods.
The test worked mostly well, I need to adjust the central idler wheel a little (second video) as everything pinches when I pull the belt tight (there is a reason for the middle wheel if anyone fancies a guess) (no specific file)
