Cyclone (Circuit Cloner) is a design for a CNC mill intended for PCB manufacturing.
It is a work in progress, looking forward to your suggestions and improvements.
- 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 Obijuan (http://iearobotics.com) for naming the machine Cyclone :)

Work in progress, please refer to the pictures.
- First Z probing results are promising, read: https://plus.google.com/u/0/113437723819360223498/posts/9VCHqqnirj6 and https://plus.google.com/u/0/113437723819360223498/posts/89W2cv1fgQW
- Added the python probing script (v0.1) and Octave/Matlab visualizer
- v0.9.5 Probing a PCB http://www.youtube.com/watch?v=m5zXL8k5T9E
- v0.9.5 Milling MDF http://www.youtube.com/watch?v=2QpxjheEjEc and http://www.youtube.com/watch?v=zjav0hBtmYA
- v0.8 Drawing test: http://www.youtube.com/watch?v=Y-HSdE89JOM
- v0.7.5 XY axis test: http://www.youtube.com/watch?v=9umlq4oHG64
- v0.7.5 High speed XY test: http://www.youtube.com/watch?v=H3uYCXryj60
Bill of materials:
- 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 will be done with probing and an appropriate software.
- [99% DONE] Design parts for the X axis (this includes Z axis too, will be using a proper spindle instead of a hand-drill)
- [DONE] Design parts for the Y axis
- [DONE] Create template for the screws in the wood base
- Software, testing, milling a PCB (till then, it can't be v1.0 :P)...
Here is a compilation of links that I find interesting for the software controller:
- Examples of the PCB probing method
- Very interesting toguether with cam.py: http://code.google.com/p/pygerber2gcode/
- For arranging panels: http://ruggedcircuits.com/gerbmerge/
You are more than welcome to suggest/modify/redistribute :-)
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:
- LetÃÂ¢Ã¢âÂ¬Ã¢âÂ¢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: CÃÆÃÂ©sar Augusto FernÃÆÃÂ¡ndez 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.
