UPDATE : 31/08/2012

• Finished basic version of x_carriage
• Finished basic version of Z axis elements
• Added updated main .scad file (doboz_v2 0.1.scad)
• Added pictures and video of Z axis
• Please see the github repository for more up to date information

Descriptions This is preliminary work for an h-bot configuration based reprap, with a rather large build volume.

The main advantage of this kind of setup is its mechanical simplicity, so with that in mind, I plan to make this very easy to build and hopefully just as easy to calibrate etc.

This is of course fully parametric!

Dependencies -Requires the MCad library

Specifications

• H-bot design
• Maximum build size (not set in stone): 220350400 mm

Media

• first X/Y movement test of prototype (running Marlin firmware with CoreX/Y support enabled) http://www.youtube.com/watch?v=a4HLpNbQznU&feature=g-upl

-first Z platform movement test: http://www.youtube.com/watch?v=IwWGr_ky8B0

For now this is still in the very early prototyping phase, so almost nothing is in a 100% usable state, but I hope to have a fully working prototype by September. Until then, expect the files to change a lot ! (and feedback is always welcome)

I will update files here regularly , but you can always find the latest version here https://github.com/kaosat-dev/Doboz-2

Things that are finalized:

• X ends
• X carriage
• Z axis elements

Next to be finalized: Extruder, hot end holder etc

Not done at all:

• "box" structure angle elements : not

Bom:(totally incomplete for now)

• 8mm smooth rods (4X for X/Y axis, 2x for Z axis)
• lm8UU linear bearings X10
• 5mm wood plank (used for build platform)
• 4mm dia nuts & bolts (12mm long) X6 for x_ends
