Huxley

I'm building a RepRap Huxley, printing parts on the HackLab's Makerbot.

Components

• Cartesian Bot: RepRap Huxley (formerly Mini-Mendel)
• Extruder/Hot End: Universal Mini Extruder modified for bowden cable
• Electronics: Sanguinololu

Status

• 2011-12-11: Searched for a place to buy Sanguinololu PCBs, after shipping all of them are more expensive than just making them myself. Sent gerbers to Laen. Parts still need ordering. Ordered a hot end part set for the Universal Mini Extruder as I have no way to machine the brass parts required.
• 2011-12-09: Pololu order arrived, now have the steppers and drivers required. Still need to order Sanguinololu.
• 2011-12-06: More work on parts lists, printed a bunch of actual bot parts.
• 2011-12-05: Printed the fixed block with no issues. Started putting together parts lists.
• 2011-12-04: Printed all components for the extruder other than the fixed block. The duct-1 component failed 95% through the print, I think it should be okay as-is, but if not a separate extension piece could probably be added. Decided on Sanguinololu electronics, ordered 1x NEMA11 stepper, 3x NEMA14 steppers, and Pololu stepper drivers from Pololu. Still need to order Sanguinololu itself.
