This page will document some changes I am planning to make to a version of Mendel that has the following properties:
- 1. as simple as possible, but no simpler
- 2. maximize build space
- 3. minimize print/construction time
- 4. minimize cost
The main focus is optimizing Mendel to increase possible reproduction rate while not losing any build volume and maybe increasing it. A big part of that focus will be simplicity (Not necessarily self-reproduction but ease of reproduction). Some quotes that inspire me:
- “Simplicity is the ultimate sophistication.” - Leonardo da Vinci
- “Everything should be made as simple as possible, but not simpler.” - Albert Einstein
- “Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.” - Antoine de Saint-Exupery
Things Being Considered
This involves many designs already made by Vik and others currently working on the Mini-Mendel development. One area where I differ from the current Huxley/Mini-Mendel development is that there are certain design complexities in both that I would like to eliminate. (i.e. X-axis belt arrangement, all three axis bearings, etc...) It may involve some of the following:
- 1. reduction in number of bearings
- 2. adding more low cost ubiquitous vitamins
- R/C car gears for the extruder, springs for the bed, etc...
- (I know this is backwards from a lot of other development)
- 3. optimizing all parts for plastic volume, print time, etc...
- looking at fill patterns, hole shapes (square vs round), etc...
