Description

Another idea for a foldable reprap :)

A little more on the wiki : reprap.org/wiki/Mondrian

And on flickr : flickr.com/photos/watsdesign/tags/Mondrian/

Github repo here : github.com/EmmanuelG/Mondrian

I'm working on the XY platform for now, as it could be used in several assembly, then will make the scissor-Z which will be most of the work I guess (contributions to firmware adaptation will be more than welcome !)

thanks i was wondering are you enabling corexy i did not see it in the latest firmware i checked? i have an h bot and i am chasing an almond shape circle issue. i have found a fix but want to know what others did to fix the issue. thanks

Yeah I changed the name to "Mondrian" to avoid confusion with the FoldaRap (since it's evolving in v2)

i would like to see your firmware but the link goes to a page that is not viewable.

very cute! how is the progress on this?

The non-foldable version is soon printing :)

Hi, great design! I love the use of the belts in the extrusion channels. I've learned a lot by looking through your github. I'm building an H bot using spectra cord instead of belts and wanted to ask two questions. 1) When you did your research, did you find any significant advantage to the H belt configuration when compared to something like the approach used by CoreXY? 2) On your latest sketchup model, you show three extruders spread across your X axis. Is that just testing ideas or have you come up with something that's going to blow our minds?

Big thanks for posting your work. Much appreciated by the community. Good luck on the next steps, looking forward to seeing the final product.

1) CoreXY is also an H-bot, but it cross the belt in an awkward way, I prefer this simpler way

2) It's just a design tip, to see/have in mind the mini/maxi positions of the X-carriage, but I plan to have at least two hotends with this previous idea reprap.org/wiki/RepRapPro_Dual... (not tested yet)

Thanks :)

After a few revision and by using linear bearing pads, it is now moving perfectly in XY ^^ http://youtu.be/fmRBO8UZGwM

does the firmware require any special changes to use h-bot movement?

watsdesign on Jan 25, 2013 said:

yes, you only need to uncomment a line about CoreXY feature in config.h, and the inversion of the X and Y motors (in my case it's false false) https://github.com/EmmanuelG/F...

I do not consider myself stupid but any means.. but i have no clue how 2 motors on belt allows for x to move on its own like is shown in the videos on your flickr stream. Any links or something i could go read to get my head around it.. a quick google search of H bot or H gantry get me no where fast.

Excellent work. I have a long list of customers in the medical and silicon fab industry that are searching for 3D Printers they can operate in clean rooms (Positive pressure). They all worry about exposed belts. While these belts look clean, we all have units with small patches of belt dust at one end or another of the axis's. A unit like this seems to be an excellent way of reducing random particles. Can't wait to see the final unit!

Then I think you will like the new corner ;) http://www.flickr.com/photos/w...

watsdesign on Dec 24, 2012 said:

Interesting ! I didn't knew about that. I wanted to keep them accessible but one could fully enclose the corners for this kind of application.
Thanks :)

Great work guys now like to see it in working.

watsdesign on Dec 24, 2012 said:

Hmm printing, not yet, but making the XY moving was easier than I thought ^^ http://www.flickr.com/photos/w...

NewPerfection on Dec 23, 2012 said:

Looks great! I like how the belts are hidden in the extrusions. I've been wanting to get away from the moving y-platform, and this looks like a perfect way to do it.

watsdesign on Dec 24, 2012 said:

Thanks! Passing the belt in the extrusions was one of the little things I wanted to try, just to see if the intuition was good :)
