Though I see no requirement for it for faster prints it does look cool.

easier to print and view.

They have a free cad program you can download.
so you design the part(s) select options and summit the info for a price quote.  IIRC the parts for the lyman extuder were soured and specified through this site.
They have tutorials to help in the design process.
The density of Aluminum  is 2.7 g/cm^3  roughly 3 times that of pla.

Great find!  Looks like I need to go no further...don't really have much more time before the Holidays anyway big_smile

I do agree that while this is a cool mod, there are other things like fishing line, etc. that will help with the backlash at higher speeds...and the aluminum will contribute to greater mass being slung around...

But if you only change the carriages, it doesn't reduce backlash enough,
More important mod are the direct drive on 6mm rear rod, a driving shaft
for Y carriage, and use GT2 pulleys and belts.

My interest is mainly now in how cheap we can actually get these machined. If they are reasonably priced I'd love to own/see some so I can have ideas for what I can get machined in the future. big_smile

If anything, I'm slightly concerned about the additional mass being slung around, especially at high speeds. . .

Here's the thing about all of this (an effort I support) I think we tend to get all excited over the whole "Speed" thing.
I have watched that video over and over,  I am not convinced I can't already print that fast.  Of course I don't know what the actual numbers are so I have to just try and judge it.  What I see is the Y-belts flopping during direction changes and no matter how solid we make the carriages backlash is still backlash.  And although with a print of that nature it is difficult to see any ill affects from the backlash, it must be there.  So was the extrusion rate manipulated to cover some of that up?

I guess what I am getting at is for those of you that have not yet upgraded to the fishing line,  wouldn't that be a much cheaper and effective upgrade?  I have been swamped with year end stuff at work but when I get time I am going to print that (fast) and post up a video.  I think you will be amazed at how rigid everything is.
So for as much as I like this idea I really enjoy being able to design and redesign the carriages based on my needs.  Lets face it things change a lot in the world of 3d printing (Think the next Bulldog or E3d).   

So for now keep up the good work and let me know if there is anything I can help with smile

If nothing else, perhaps just a thin wall in between the two sections. In fact, it could go over the top of the empty space and you could put the belt attachments there, sort of like is done in the lawsy carriage. Will the space between the bearings here be an issue at all? Can't imagine why it would, I'm just brainstorming smile

For compatibility, I think the bottom of the center carriage piece should mimic the mounting holes of the lawsy carriage, simply because there are a lot of things utilizing that spacing.

Nice work IronMan!

Linear Bearings not shown...chose to go with the clamping action on the gantry sides per elmoret's suggestion; then use a half-clamp for the carriage.  Need to pop on a front plate for the stepper motor and hotend mount...

3D PDF attached.

Feedback?
