A while ago I wrote a program to read and solve the Professor version (5x5x5) of the Rubik's cube. I then decided to build a robot to actually do the reading and the moving...My first prototype was built in plywood, but then I decided I wanted to build something that was less prone to defects , so I got my first Makerbot, redesigned most of the components, and started printing!This is an ongoing project, and I still have my plywood components working, waiting to be replaced by their ABS counterparts.The electronics is based on an Arduino that reads the input from an external PC where the Solver software runs; it then drives the 12 servos that manipulate the Cube.MachineEnsemble.scad is just meant to show how the 6 internal cages work together, and is based on the other printable files. By turning on automation on the 'pos' variable, it shows how the cube is manipulated.Two of the main components (Cage and IntTransmission) are too long/big to be printed in one piece on my Makerbot, so I had to devise a way to break them up. That's why I have "CageTop", "OnePiece", and "CageBottom" pieces.I've tried several existing thread 'things', but I ended up designing this very simple one, which is easier to print.I have not (yet) included the outer shell of the machine (a 780x780x780 plywood box) or the internal cage holders (mostly plywood, with printed ABS bearings and bearing holders).Nov-13:After a forced stop in printing (apparently my TOM's motherboard and extruder controller were fried!), I restarted by tweaking print parameter for the 3 components of the main cage (CageTop, OnePiece, CageBottom). The main issue wasthe curling upwards of the 4 corners; after several tries, mainly tweaking infill% and plaftorm temp, I got very good results with 20% and 135, respectively. All other parameters I found work best at their default values (0.35mm layer height and 225C extruder temp, 30 feedrate).I had to get rid of the Kapton belt on my ABP to get more reliable results.
