News

Hardware

• v0.9.6 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)

Software

• 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

Firmware

• No news, it is Marlin with support for G30 probing command

Bill of materials

https://docs.google.com/spreadsheet/ccc?key=0AsQp8IK25R4IdGk3LTdOWmpFR0Nrc0RhaVJaUC1CMUE
TODO: Add general hardware, motors and electronics to the list.

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 will be done with probing and an appropriate software.

To-Do list

• [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
• Hardware: Reinforce left&right frames
• Firmware: Test various buffering/jerk configurations for Marlin
• Software: Export Z probing to a standarized file, add bilinear interpolation
• Manufacture a PCB (till then, it can't be v1.0 :P)...

Special thanks

• Y axis improvement by yOPERO https://github.com/carlosgs/Cyclone-PCB-Factory/pull/1
• 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 :)

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
• 100x160mm workspace: David Martin https://dl.dropboxusercontent.com/u/16122275/PandaCNC_credit/workplace_size.png
• Using gears to drive the X-Y axes: Guillermo Welch https://plus.google.com/u/0/101232926728463427403/posts/QjZGNcWcgGg
• 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.

Assembled machine (v0.9.5)
