UPDATE : 02/05/2017 Switched license from CC NC to public domain ! 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 More infohttps://github.com/kaosat-dev/Doboz-2 Instructions 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
