Member of the Core Team.
Primary system administrator for Reprap servers.
Built a set of Reprap v1 electronics, which worked to the extent of driving one small test stepper motor.
Planning a Mendel build in summer 2010
Mendel Build Goals
- Low cost (under US$500 if at all practical!)
- Improve the mechanical build docs based on the experience putting them together.
- "Very standard" Mendel mechanics (for ease of getting help with them!)
- "Very reliable" extruder (so I can make parts sets)
- Some experimenting with electronics is OK, esp. to reduce cost.
Current Ideas for Parts Acquisition
Electronics:
- Seeeduino Mega fully assembled from http://www.nkcelectronics.com/seeeduino-mega-fully-assembled.html
- 4 Pololu Stepper Controllers, see Pololu_Electronics
Steppers:
- 4 steppers, maybe Pololu 1209s (reduces number of suppliers to use Pololu for these)
Mechanics:
- Hardware Kit from Ultimachine (because I know the least about the mechanics, spending $$ on a kit is OK!)
Extruder:
- Not sure, Adrian's or Wade's geared stepper driven.
Feedstock:
- PLA, probably natural, from Ultimachine.
Things to Print (when it works)
- A set of RP Mendel parts to sell, to get more Reprapping budget
- At least one set of RP Mendel parts to give away, to ease my conscience (!)
- A second set of RP Mendel parts for myself, as spares or for a second Mendel.
