Oh, and the final form of my Y stepper assemblies. The belt runs under the Z steppers which saves I think like 22mm per side. One of the next things to make is some new side plates that close up a lot of the gap from the OG vertical Y steppers. I kept the mounting points the same (why it’s a weird triangle shape). Just got some 1/2" mdf a couple days ago to make them with.
Had to come up with my own clamp and tensioners which was fun. Highly specific to my workbench shape.
