Yeah, A part list would be great! (and maybe some pictures) O:-)

just wondering if you have made any progress with this. It look like a very interesting mod. I would love to try it with my cupcake. Could you list the parts I would need to order from McMaster? Thanks

Wicked stuff! Love the idea, make so much more sense to move the head than the print.

Any updates on parts lists? Being from Canada I will have to source from somewhere other than McMaster as they do not ship to Canada anymore.

Also, have you considered nuking the top cupcake plate? Mounting the pulleys and all the mechanics above? That would likely increase the print area by quit
e a bit.

hi guys,I'm from Spain and I am interested in buying a 3D printer but I'd rather build it myself because I have the necessary machinery to manufacture. The problem is I can not find any plane of the Rapman or Makerbot printers. Pandelume, I saw that you're built your own 3D printer and I wanted to ask the drawing 3D or some reference to start making plans. Nothing happens if you don't pass me the draqings. I know the effort that means. Thanks for reading.

Your work is fantastic!!

I'm glad you like it! My plan for releasing the documentation was to post DXFs for the lasercut parts (one set for a new enclosure and one set for modifying the cupcake stock parts) and releasing the finalized gantry parts as STLs for printing. I'll also post a few drawings showing details of mechanical assembly and a BOM with supplier information.

In other words, I wasn't intending to do a full drawing set for processes other than 3D printing. If that's what you need to move forward, however (if, for example you have a mill but not a 3D printer), I'd be happy to make drawings for the printed parts - it'll just take me a bit to finish them.
Please let me know what you need and we'll go from there.

Also, just in case you'd prefer either the cupcake or the thing-o-matic, the files - or at least links to the files - can be found here:

thing-o-matic http://www.thingiverse.com/thing:4973http://www.thingiverse.com/thi...

of the structural parts for these are lasercut, but you could tweak the DXFs for construction on a router if you prefer.

What I have in mind is from the MakerBot operation and structure, build a machine with good materials, good housing, more area and more accurate printing. To do this I have a water cutting machine, machining centers and more devices construction.

I much prefer the extruder head Rapman but not sold with electronic devices and do not think they are compatible the MakerBot.
What should I buy components to build it? The extruder head, electronic components, the interface, engines ... If I could put what I need would you do me a favor. Only ite
ms that have to buy.

Thanks for answer

My attempt at this has stalled... but have you though about switching to a cantilevered Z stage? That allows you to use the pulleys from the original Z-stage and saves a pile of money (those pulleys are very hard to find cheaply).

I was also having real trouble coming up with a compact belt clamp design. I like yours and might have to steal it :-D

Oh, and what will you be building that blue part of the extruder mount from? I'm running a PLA mount and cooling it with a fan. That keeps it from going all soft, but your moun
t is much closer to the hot-end than mine (although a similar level of compactness).

I think you might have inspired me to un-stall my build!

Duh... looked more closely, see that you are using a z-rider...

Looks like an awful lot of new holes in the cupcake though =-O

"NOTE ON LICENSE: I haven't seen anything of the Ultimaker apart from the publicity shots, which is to say that I haven't done any work with the source files and I don't know what license they will be released under. For now I've gone with GNU-GPL so that this is compatible with the cupcake, but I'll update as necessary when the Ultimaker is released."

If this is your own design-drawing (which I presume it is), then there is no licence issue, it is all your own work and you are free to choose whichever licence you see fit. Seeing a few pictures does not make your creativity somebody else's.

Thanks for the comment - my interpretation is more or less the same as yours. On the other hand, I'm hardly an expert in licensing issues, so it's not completely clear to me how much access to a GNU GPL (which I presume will be the Ultimaker license) design I have to have before derivative work falls under the license. For that matter, I got the inspiration for this from seeing the Ultimaker pictures but since it's not for the Ultimaker and all the development was done independently I'm not sure that it's 'derivative' in the sense intended by the license.

Really, though, I would release it as GNU GLP or open hardware anyway. The note on the license was simply to let the Ultimaker people know that I don't mean to step on their toes - not a major worry, but it seemed like the right way to approach the issue.

Awesome! Just few days ago I thought to myself that this mod is only a matter of time to appear here :)

But when adding this mod to your bot.. is it a makerbot anymore or something even greater? :)

I think this is the 3rd one... but its certainly looking better than mine!

You're right. I totally forgot the one you made. I'm sorry, my bad.

Have you tried printing it yet?

That gantry was originally designed by Ilan Moyer for his Fab in A Box project: http://mtm.cba.mit.edu/fabinabox/blog.htmlhttp://mtm.cba.mit.edu/fabinab...

Great Work! It actually has the same approach as the Ultimaker, by using its linear shafts also for moving the x,y axis, printhead. Linear shafts that also rotate. This way the height of the x,y system can be very compact.

Ultimaker might not of been the first. Someone probably thought it up 100 years ago. However it certainly gave the design visibility and showed its potential to DIY printer community and that's valuable.

Yep, there are cranes that use a nearly identical design, and I've built similar systems to fly performers in theaters with no fly tower. Saw it used in the mid nineties for stage magic (one on top of a box, one below, line between held under tension) One of the best levitation gimmicks I've seen.

Ok, I'll take your word for it. I have heard of Fab in A Box, but I'm not familiar with the details of the machine and didn't know it used this type of gantry.

You could also argue that it's inspired by the ulitmaker. There are quite a few gantry systems out there now. Of course you could also argue that these were all inspired by stratasys patents that are now expired... at least in the US.

Definitely a cool upgrade!

Really, really cool.
