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.
