Hardware for Cyclone-PCB-Factory

Render (v0.9.7)

To-Do list

Fix this: The linear bearings of the X carriage must be glued in place (use epoxy or similar) since vibrations produced by the spindle motor move the bearings out of place.
Reinforce left&right frames
Reinforce screw holders in the Z axis parts
Add Endstop holder files (same of Prusa/Mendel)
Create holder for a vacuum cleaner
Create assembly instructions

News

v0.9.7 has an improved Z carriage: uses much less plastic, it holds the spindle tightly and leaves more metal surface exposed for better cooling.
v0.9.6b has a robust Y axis motor stand (improvement suggested and tested by Yopero), and the Z carriage now shows the name of the machine (how cool is that? :P)

Notes

Using a thick wood piece as the main base.
As shown in one of the pictures, a cheap dremel-like drill has nice bearings and is a good option as the main tool. Finally it will be using a proper spindle (check the BOM for the reference).
Desired working range of >=100mm for the X axis and >=160mm for the Y axis.
Parts are designed to be printable with the small volume of a Printrbot Jr
Bed leveling is done with probing and an appropriate software.

Special thanks

Z axis concepts by Quim Borras and the spindle motor holder by Misan were really useful!! Also, Diego Viejo's machine was of great inspiration for the Z axis (https://plus.google.com/u/0/photos/113930344830086538817/albums/5868944432651911713?authkey=CLDJgdehlN773gE) Thank you all!!
This design woudn't have been possible without the encouragement of the Panda CNC community (https://plus.google.com/u/0/communities/102402711800402614517)
Also, thanks to Juan González-Gómez (Obijuan http://iearobotics.com) for naming the machine Cyclone :)

Credit for the ideas used

The origin of Cyclone took place while I was inside the Panda CNC community (https://plus.google.com/u/0/communities/102402711800402614517). This is from December 2012 to mid-February 2013.
Here is the credit for the ideas that were used:

Let's design a 3D-printable CNC for PCB milling, it will be named Panda: Guillermo Welch (mid-December, via Google Talk)
X carriage rod distribution: César Augusto Fernández Cano claims Cyclone's X axis is a derivate of his concept: https://plus.google.com/u/0/111421387442355054591/posts/QrfYtEuZBaj

Regarding the woodbase: Guillermo Welch always contemplated the possibility of attaching the machine (optionally) to a woodbase. I decided to use the base as a main structural part instead. See https://dl.dropboxusercontent.com/u/16122275/PandaCNC_credit/woodbase.png (screenshot from https://plus.google.com/u/0/113437723819360223498/posts/8LDCSSVWqCS)

Please note I have taken screenshots of the post that are on the closed G+ Panda community (https://plus.google.com/u/0/communities/116318709564872967169). You can register and see by yourself.

All other development present on Cyclone has nothing to do with Panda and is not related to the Panda project.
