The Quantum ORD Bot

As a reference point, this size uses less than $15 worth of Makerslide extrusion. You also need about $45 worth of MakerSlide wheels, spacers, etc. The Makerslide parts are available at the MakerSlide store. Be aware the rail is released in weekly 'production batches' and sells out very quickly. It is 'restocked' on weekly basis.
I have attached the complete 3D design in STEP format plus a DXF of the flat parts. If I can generate enough interest, I may have about 50 sets of parts fabricated and offer kits. That would be for the mechatronics platform only. The extruder, electronics, etc would not be included.
Why spend $200 for a set of printed parts when you can have everything you see here, including motors, belts, pulleys for about $200?
1. I plan to change the crossbar handle thing to an extrusion to make it more scalable.
2. The 'quantum' design currently uses NEMA14 motors. I plan to tweak the parts to be compatible with NEMA17. This just adds a second pattern to some parts.

I regularly print at 200% speed (normal is 40mm/second, so 80mm/second) and the parts come out great. The key is to start at 100% speed for the first 3 or 4 layers to ensure adhesion to the plate, then crank up the speed at the LCD/Control. Here is a picture of a part I printed with these settings... http://i.imgur.com/9fOLV3M.jpg .The parts are accurate to +- .001".
There are a ton of photos on the buildlog.net web site. Â Documentation and 3D source files are also there. Â A few people are selling kits for them too.
