From a box of parts to a working desktop gantry style CNC mill
The Z axis is the most complex step so far. The hardest part has to be the Z motor mount plate. Screws going in from both sides, thin nylon spacers stacked between the two plates, and a flange bearing in the middle. This thing was kind of evil to assemble.
The Shapeoko 2 assembly continues with the carriages. The carriages are laser cut sheet steel, and need a whole bunch of parts screwed into them. Motors, V-Wheels, Smooth Idlers, everything goes in. The manual is silent on aligning the pinion pulley with the belts, so I did my best. Hopefully when the belts get installed I won't be too far off.
There are There are three carriages to assemble.
I started with cleaning off my rather cluttered workbench, and laid out the parts for the S2.
The S2's assembly starts with the V-Wheels and smooth idlers. Each one has two bearings, a spacer or washer, and a Delrin shell. Everything presses together, but you really need to have a screw in in the center to hold that center washer in place.
There are a lot of these. 20 V-wheels, and 6 smooth idlers.
