The basic design is still being worked on, and is subject to major changes.
2014-Oct-31 I've assembled a prototype Snappy RepRep, and was able to run it through some motion tests. It works! Mostly. The Z axis wobbles a hell of a lot with the lifter screw, so I'm abandoning that design, and will try a direct drive approach. I was able to turn the printer on it's side, and it was still able to drive the X and Y axes against gravity, so I think that should work for the Z axis as well. If tests prove otherwise, I can always try gearing down the Z Axis.
The eponymous snap joiners have been tested under fire! They take a fair bit of pressure to get to snap into place, but can be joined by hand. For this test, I connected three Z platforms together and put a hefty weight on the end. Once attached, they were solidly together, and didn't even wiggle. Given that the rail parts used for the extruder cantilever have even larger/stronger joiners, and fewer joints are needed, I no longer worry about it holding up!
The X/Y slider got it's first motorized test, and it's a success!
