(Updated 4th March 2013)
(Added a 4 bearings model and a new holder model)

This is a modular x-carriage that uses strong lm8uu bearings. It is inspired by Jonas Kühling carriage. The problem with his carriage is the weakness of the holders (as they are printed vertically)


Downolad the STL and print.

If you want to modify the files you must install the C++ OOML http://iearobotics.com/oomlwiki . The parts are parametric, so it should not be difficult to change most parameters.

Managed to print two of the clamps, but the third one has failed on me now for 5 times.. It just keeps on popping off of the printbed. I am going nuts! :D Whieeeeeee

Do you print over Kapton? Try with hair spray or acetone with little ABS solved. NO KAPTON REQUIRED :)

Yep, actually my first prints were on ABS glue selfmade with acetone, I tried to rule out the 'handmade' factor here so I ordered Kapton and still it just pops off after some time. Just cleaned the kapton with Acetone again, will give it another try today ;)

I have also fixed my smashed layers, it was because my hotend wasn't secured well enough. I have to print a new extruder because my hotend and extruder don't work that well together.

Maybe you know which extruder I have to use, the width of my hotend connector that goes into the extruder is 17mm. A strange width if you ask me.

I would modify directly the scad files for the Jonas Kuheling extruder. There must be a parameter indicating that radius.

Nice design, can't wait to fit it on my Prusa :)
The lm8uu_holder however does not fit on the xcarriage, I had to trim one shoulder on each with a blade to make it fit.

Thank you for your feedback. Do you think it was a resolution problem of the printer or a design problem?
I will update the STL as soon as I arrive home.

It was the design; the angle of the holder and base don't coincide and I had to remove quite a bit of the holders' shoulder to allow it to fit.

I've been using it for a while now and really like it btw!

Thanks for the feed-back. I have to print my xcarriage because former one (Jonas) has broken after tons of printing. I will check this.

I like the idea of C++ OOML. Does it have the same limitations as OpenScad?

What do you mean by limitations? Up to now the generated code is OpenSCAD, so it cannot do anything that cannot be generated using OpenSCAD, but the way to design things is completely different: it is based on Object Oriented programming.

Then the OOML adds many functionalities not present in OpenSCAD, like relative rotations and translations, Euler rotations, attachments, system references, and some primities (like RoundedTablet) not present in OpenSCAD.

In the (near) future OOML will have its own viewer and STL generator, but up to now we have relied this task to OpenSCAD, as our goal was to test the viability of Object Oriented Mechanical design

Thank you. It would be cool, if you could move,rotate,resize objects in your viewer and receive  the changed parameters back in c++ code.  With that viewer/editor you could develop a new user interface for people who don't want to set parameters in the program code.

Yes! That's exactly the goal. I just need time and some collaboration. I hope we will arrive up to that point!!
