Description

Redesign of the reprap Huxley, inspired by the Prusa Mendel, but with some significant differences.

Key features:
- Small footprint
- 140x140x100mm build volume
- 1.73mm bowden fed filament
- Resistor heater block hot end
- Milled Aluminium, nichrome heated bed
- Single board Arduino motherboard

Actually, he's selling them here http://www.indiegogo.com/RepRa... :)

Love mine! Can't think of a better (or less expensive) way to start printing in 3D. :)

Great little machine! I love it already! :)

Is this missing some kind of bearing holder? I have lots of little recessed squares where bearings should be but I don't see a file that matches

I'm printing this now and I think I'm missing the y-idler-bracket.stl. Can you upload it?

y-idler-bracket uploaded.

WilliamAAdams: good idea. I think there is scope for taking out maybe up to half of the frame nuts.

ZNahum: The prototype uses the RAMPS board from Ultimachine, but I plan to use the Generation 7 electronics on future machines.

The UP style nozzle is similar to that used by the UP 3D printer from www.pp3dp.com

Ahasuerus: Being smaller than M6, using M4 threaded rod means that the Z motor coupl
ings can be smaller as well as the X motor bracket and X idler bracket since the M4 nut is smaller than the M6 nut. It should also mean we can use smaller motors on the Z axis as the thread pitch is less so we need less torque at the motor shaft, but I've yet to source motors as small as I'd like.

curious if there is any particular reason to go with m4 (i'm guessing) on the z-threaded rods instead of sticking w/ m6.

When you say "up style" nozzle, what exactly do you mean?

Like the UP! printer

Single arduino mobo? What type are you using? Are you using RAMPS, Gen 6, or some other version? I'm going to use the UltiMaker RAMPS 1.3 board for the prusa I'm making.

Some day I will make one of these little Huxley machines.

I have been wondering. Since it is so small, and the forces are not as significant as the larger machines, can you get rid of most of the holding nuts? Primarily on pieces like the vertices and motor mounts.

There's already threaded rod, and if you print the pieces with slightly less diameter
, then the rod can just thread into the plastic.

I've done that on my linear slide thing here:

Just a thought. Reducing vitamins makes the build slightly cheaper, makes the build faster, and simpler, and requires fewer different types of materials.
