While reviewing certain aspects of the Revision 2 design for the Gemini 3D Printer a few minor design issues have come to light.
Unfortunately for this project, I was busy doing other things over the course of the Summer and needed to take a break from this machine.
The Devil is in the details they say and some of the design semantics of the X Carriage and Hotend Assembly have gone through many stages to evolve to their current state. While the modular design of the current components is pretty decent, I feel it can be made more elegant and functional with a re-working of how it assembles to the printer.
I spent a chunk of time over the past few months learning how to make complex parts within OpenSCAD to allow for easier revisions of designs and parametric settings to allow for hardware variations. This new skill will be used with the redesign of the Gemini X-Carriage and Hotend-Assembly.
The source and printable parts are being reorganized into sub-system components and a private JIRA instance is being created for task tracking and documentation. These steps will bring a more orderly development approach to the creation process.
Since the primary goal of this project is for me to have a machine with the size and capabilities of the Gemini, some of the focus will be changing in terms of the design scope for this prototype.
Enough will be changing that I suspect that this will become Revision 3 of the Gemini 3D Printer and Revision 2 will become just a stepping stone from the initial proof of concept prototype to a more complete system.
