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
The Z Axis should be put in after the frame and Y axis have been squared, and trued. Information about how to do that can be found here. You should have tightened all nuts and used threadlock on them if you are going to (I recommend that you use threadlock). If you perform the following steps before squaring and trueing up the frame and Y axis, it will be in the way and will make that process more difficult.
Drive Rods
On the left is a picture of the parts used to assemble and prepare the drive rods for the Z axis. On the right is an assembled and prepared Z Drive rod
- (2) 6mm threaded rod (the las 2 in the set) they are about 215mm or 8-1/2" long
- (2) Printed Drive Cogs (shown with nut already installed)
- (2) 626zz bearings
- (10) 6mm nuts
The following are shown in the picture but are not used until the next step (but I mised them in that picture...)
- (6) 3mm X 20mm bolts
- (6) 3mm Nylocs
- (12) 3mm washers --ok... the picture only shows 6...
Begin by putting a 6mm nut into the end of each of the printed cogs. I use a torch to heat the nut slightly (don't overheat it) just like we did for the Z Nut Retainers on the X Axis. I thread the nut onto the end of the threaded rod to heat it (don't burn you fingers!).
Next, assemble the Drive rod with a 6mm nut, the bearing, then three more 6mm nuts, followed by the cog. Place them all on the end of the rod until the rod is flush with the nut in the drive cog as shown on the right.
For now, we remove the drive cog from the drive rod. At this time I rcommend that you put a small amount of threadlock on the top nut and on the bottom nuts. Be careful not to get threadlock into the bearing, since threadlock can ruin the bearing.
Install the X Axis onto the Z drive rods
You will need the Huxley, the assembled X Axis, the two threaded drive rods from above and the printed drive cogs, along with the 3mm bolts, nuts and washers listed in the step above. NOTE although this picture has the Z smooth bar clamps in place, we do not yet put them on, that comes in the next step -- my pictures got ahead of my instructions, sorry.
We start by turning the Huxley upside down (or almost upside down) as shown in the picture on the right.
Then Place the X Axis into the space where it will be, put the top of the X Axis towards the top of the Huxley
Put the Drive Rods through the Z driven unit, and the Z Combo unit and thread them into the nuts in the Z Nut Retainers on the X Axis, I threat them until they are about two inches I also try to get them nearly even (it makes squaring easier if I get them close now).
