Note: updates have been made to this design and are now available through the links on the instructions tab - no need to maintain two locations. For instance: there are four Z axis options now available, tailored to fit your build size and preferences. These include: Original (2 rear leadscrews), shown modeled in red Original offset, featured in OpenBuilds rework and D-bot remix, shown modeled in purple Front back, as used by AK-EriC in the OpenBuilds rework, shown modeled in green Three lead screw options developed by AdamCooks on OpenBuilds Check out these options: Parts & BOM:http://www.openbuilds.com/builds/c-bot.1146/ Discussion:https://plus.google.com/u/0/communities/106707229610255461517 Build Blog:http://www.akeric.com/blog/?page_id=2 Build Guide:http://www.thingiverse.com/thing:1001065 Modifications & Accessories:http://www.thingiverse.com/cfeniak/collections/c-bot This is a Core XY printer utilizing open builds V-Slot rails. I designed this myself with specific goals in mind: Not to use any linear rod/bearings, I chose V-slot for all guided motion instead To avoid crossing belts found in most core XY printers; I used two offset parallel belt runs Run the belts through the extrusion whenever possible for a cleaner final product Make the entire setup easily modifiable and adaptable so others can use it with alternate bed sizes - I'm using an 8x12, but switching to an 8x8, 10x10, or 12"x12" is as simple as cutting your extrusion to different lengths; no part redesign required Minimizing unique 3D printed parts was also a goal, but since I already have a working home-built OB1.4, this goal fell by the wayside; you can see printable parts like corners and tees that can be replaced with items from the open builds parts store.
