Under nocircumstances shall Carlosgs be liable for direct, indirect, special, incidental, or consequential damages resulting from the use, misuse, or inability to use this hardware/software, even if Carlosgs has been advised of the possibility of such damages. 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 Videos: -- - v0.9.6 Y axis concept by Yopero http://www.youtube.com/watch?v=XzcobonQP40 - 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: -- https://docs.google.com/spreadsheet/ccc?key=0AsQp8IK25R4IdGk3LTdOWmpFR0Nrc0RhaVJaUC1CMUE 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)...

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.

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.**
