HuxleyFrame

General

This page and its peers should guide you through assembling a RepRap Huxley from the TechZone kit, or from parts you have printed which are the same as the TechZone parts. It is a work in progress, and needs some help, feel free to edit this document to add comments of you your own, or contact us [here] and send us messages asking us for better clarification or details.

I am starting by posting the pictures I have, and over the next few days, I will fill in the instructions and detials (24 Dec 2010)

Thanks,
Lambert (TechZone R&D/Support/Documenter)

You can access this page and it's peers (for the other parts of the Huxley assembly from the Main Huxley page or from the TechZone Huxley Page

We Assemble the Frame as Units, the Top Unit, the Front Unit and the Back Unit, then we put them together. To begin with, we assemble parts just finger tight, and into aproximate areas. When it is all together, we will fix things by measurements, and tighten them up.

The instructions below differ slightly from the Mendel build instructions, but you can use those as a rough guide for building Huxley as well. Distances will be shorter on Huxley, but techniques and notes will translate over very well. On Huxley, the distance J1 is about 200mm and J2 is about 140mm.

Top Unit

On the left is a picture of the parts used to make the top unit:

• • (2) of the longest - aprx 295mm (11-5/8") threaded bars from your bar kit
  • (8) 6mm nuts
  • (8) 6mm washers
  • (2) Top Vertices - from the printed parts set

Simply thread the inside nuts onto the bars, then washers, followed by the top vertice pieces, more washers and the outside nuts.

Make the parts just finger tight for now, we will get the exact placement and tighten it up a little more at a later time.

It should look something like the photo on the right when you are done assembling this.

Front Unit

The parts Used to make the Front unit are pictured on the Left, and an assembled front unit is shown on the right. The parts used are:

(2) Leg Vertices - printed parts (1) Y Idler - printed part (2) Y Smooth Bar Clamps - printed parts (2) threaded rods, two of the four shortest pieces, aprx 210mm (8-1/2") in length (16) 6mm Nuts (16) 6mm washers

I have found it easiest to start by puting the Y Idler onto both bars fist, position it somewhere near the middle, we will move it to an exact position later.

Then take the bar which has been put through the small end of the Idler triangle, and call it the "top" bar, add the smooth bar clamps to this bar, as shown on the right.

Then add the legs, the inward bend of the legs points the same way as the obtuse angle of the idler triangle, the feet go down, (hopefully they are somewhat obvious).

Back Unit

Note that the rods here should be the shortest threaded rods in the kit.

Put them together

Putting together all the pieces of the frame this way is easier if you leave some space for all the printed parts to move a little. This way, if they aren't perfectly straight, they can be easily shifted into alignment. Leave them loose until the frame is fully assembled, then start tightening it down. Leave it finger-tight for now, as you'll still need to follow the procedure for squaring the frame. You should be able to follow the instructions on the Mendel squaring axes page with only slight changes to accommodate the size of Huxley.

The Z unit uses the last of the longest threaded rods in the kit.
