Re: Parallel flexure test - 11 years ago
This is a really cool, original design, Delgir. Nice work! I just saw this today and I'm super excited about it! Long ago I posted some links and notes about flexure hinges and compliant mechanisms here but as far as I know, your printer is the first that does X,Y,Z with only flexures. Very cool. Do you think you would gain anything if, instead of using the large metal flexures, you were to makby MattMoses - Polar Machines, SCARA, Robot Arms

Re: Has anyone developed Fine Text Engraving Methods? - 11 years ago
VDX has done some very fine work using lasers to engrave PCB's, plastics, ceramic tile, and more. A low tech alternative that might get you passable results would be to attach a scribe like this to your machine, and basically make precisely placed scratches in the workpiece.by MattMoses - Developers

Quotevegasloki You've already made it clear that you have no interest in doing any of the work and would prefer someone else to do it for you. This is not correct, vegasloki. WillAdams has made a number of helpful edits to the Wiki, and I hope he continues to do so.by MattMoses - General

Hi Fraser, You should thoroughly research the Kartik M. Gada Humanitarian Innovation Prize. The relevant history is archived in this subforum and this wiki page.

Re: trying to build our 3D printer in Syria - 11 years ago
There are many examples of people making makeshift 3D printers out of whatever materials they can find. Maybe this information is useful to you if you don't have access to sophisticated kits or hardware.

Quotegoldenmongoose Huh? OK, so you don't come right out and say "No, I am not ohioplastics" but instead you act confused.

Re: Stratasys sues Afinia - 11 years ago
goldenmongoose, if you would like to have a heated discussion about international politics, there are plenty of places to do that on the internet. The RepRap forums are supposed to be a place where people discuss self-replicating manufacturing tools (of which 3D printers are a subset). The RepRap forums are not supposed to be a place where anybody posts any thought about anything that pops inby MattMoses - General
Re: Stratasys sues Afinia - 11 years ago
It would be nice if we didn't get this thread heated up again just for the sake of having an argument about politics. As far as I know, there hasn't been any new (public) developments regarding this case for quite some time. (Which is probably why the thread was cold since Feb 02 2014.) Perhaps we can save the political debate until there are some new announcements regarding Stratasys/Afinia?by MattMoses - General
Re: Hacking a Makerbot Replicator 2? - 11 years ago
For your application, you might be better off getting a small CNC milling machine, instead of something designed for 3D printing. Shapeoko and Sherline are two possibilities. You can also search ebay for "motorized XYZ stage" and things like that...by MattMoses - General

@A2: Here is what OP said: QuoteKyle R Are there any Cartesian printers that have a stationary bed, with a design that allows the head to travel in 3 directions, or an open-source project like the Makerbot printer with a print head that travels in the X-Y plane, and a stage that travels in the Z direction?

Re: Open-source Stationary Stage or z-direction-movement Stage Printers? - 11 years ago
There is Tantillus (see also Ingentis), Ultimaker and Ultimaker 2. Two of Makerbot's early designs are still open source and still available on Thingiverse: Thing-O-Matic and CupCake CNC.by MattMoses - General
Re: Prusa Nozzle Mk2 Dimensions? - 11 years ago
I searched around a bit (I'm sure you've already done this) and the best I could find was an unsatisfying and incomplete drawing of the Mk3(?) on this site. I put a question mark (?) after Mk3 because the drawing doesn't even have the version number on it, it just says "The Nozzle".

Re: Migrate from Thingiverse release for any open-friendly site to use. - 11 years ago
Thanks. On taking a closer look at some of the items on ShapeDo, I see there is an option to clearly cite the original author and source files (see for example this hexaflexagon). This makes me feel much less irritated. (What can I say... I'm irritable.) I also see some nice original content too.by MattMoses - General
Re: Migrate from Thingiverse release for any open-friendly site to use. - 11 years ago
Comment 1: ShapeDo has been listed on the Printable Part Sources wiki page for months, along with dozens (literally dozens) of other alternatives to Thingiverse. This page was started after one of the many other bouts of hysteria following a Makerbot "scandal".

Re: Installing RepRap software - 11 years ago
Wow, yeah. That page is ancient. Note: if you click the "Build a RepRap" link in the main page sidebar instead of at the bottom (we should fix this), it takes you to this page: RepRap Options which is similar to the page you landed on but more up to date... You might find helpful information there too.by MattMoses - General
Re: Installing RepRap software - 11 years ago
Out of curiousity, which part of the wiki are you looking at that suggests RepRap Host? Parts of the wiki are pretty terribly out of date... We might need to update it if it's recommending RepRap Host. The options suggested by isonoob are more modern than RepRap Host. Just FYI, pronterface/printrun has a wiki page here and repetier host has a wiki page here.by MattMoses - General

For a more measured take on the latest anti-Makerbot hysteria, check out this article by Cory Doctorow.
