This is a Core XY, not an H-bot printer, but the two are based on the same principles for motion.

I designed this with a couple goals in mind:
-not to use any linear rod/bearings; I used V-slot for all guided motion
-no crossing belts as found in most core XY printers; I used two offset parallel belt runs
-run the belts through the extrusion when possible for a cleaner end product
-make the entire setup easily modifiable and adaptable so others can use it for alternate bed sizes
(I am using an 8x12, but changing to an 10x10 or 12x12 is as easy as cutting your extrusion to different lengths, no part redesign required)

Please let me know if I forgot anything or there are errors.

Check out this excellent build blog by AK Eric, which covers both the original build and front/rear lead screw modification:

Check out this very well documented remix that covers the offset lead screw configuration and has an amazing detailed build guide (useful for whatever version you are building):
