Tiny Boy 2 Printer info required - 6 years ago
Is there any news as to where this project went? I would like a kit as I want to experiment printing small parts with tiny nozzles. Any info would be appreciated. Its really the V2 version I want as the mechanism looks much better. Tiny Boy 2 Tinyboy2 thingiverse Did the project become the Turnigy machine from hobby king?

Re: Defining Open Source - 6 years ago
I would not worry about releasing a design derived from the GUS Simpson as the design and development was discussed openly on a public forum from 2013 onwards. Gus Simpson Development This means that the design is in the public domain and therefore is not a closed design with reserved rights by the author. In addition contributions to the design were made by other forum members, so the designby martinprice2004 - Reprappers
Re: Defining Open Source - 6 years ago
It should be mentioned here that many Reprap designs are released under the GNU General Public license. I would recommend you do the same. This and many others are "Copy Left", which basically means that derived works must also be released under the same license (ie open and the designs freely available). Bre Pettis take note! This may seem like a small point but it can have big effects. Adriaby martinprice2004 - Reprappers
Re: Kappa 3D printer - The next generation 3D printer 
- 7 years ago
This is an excellent design. Is the 3D printed prototype open sourced as I would love to contribute to its development? Because of the very narrow profile of the main upright, this machine seems the ideal configuration for a dual head. By extending the X axis by the width of the head, you could easily have dual print heads which are independant of each other. I am not a big fan of moving the pby martinprice2004 - General New Machines Topics
Re: Looking for Advice on Layout for 7-Axis Robotic Work Cell - 7 years ago
It is difficult to advise exactly as the products that will go through the cell are so varied. We also have no idea of the quantity of each item you are to produce. I assume that you will be using the robot for small batch work or one off work. The standard format for a robot cell is to have the conveyor passing in front of the robot, with the robot arm behind. Parts come in on a pallet on a coby martinprice2004 - Mechanics
Re: Four SCARA´s on one table? - 8 years ago
An interesting idea to have many SCARA arms together. It seems that you may be confused as to what you want to achieve as you are discussing two very alternative approaches. 1) 4 SCARAs in one build area. This will require a bit more programming for collision detection, but this would be quite interesting to do. The only advantage you are really getting is reduced build time. If you want a largeby martinprice2004 - Polar Machines, SCARA, Robot Arms
Re: Peachy Printer ideas - 10 years ago
I don't know whether this is possible, but you could produce a continuously rotating device and switch the laser on / off. It works for laser signwriters (You see these at concerts writing across dry ice smoke ) Perhaps just doing this to replace one mirror may make the mechanical hardware much simpler. After all electronic circuits / software are generally much cheaper than hardware. Could youby martinprice2004 - Polar Machines, SCARA, Robot Arms
Re: 3d printing using paper - 11 years ago
These are quite interesting concepts. How about a layer of perforated support gauze material, that you print on / through and after you have built it up, you dissolve it away.by martinprice2004 - General
Re: Nozzle size ? - 11 years ago
The reason I asked the question was that I'm sure a larger nozzle size would result in less extrusion pressure which could only be a good thing for reliability and easier printing of the first layer. My J type nozzle has just become all blocked up and I have ordered a new one, so I was thinking I could modify the old one whilst cleaning it up to a larger size. Its going to be quite hard to drillby martinprice2004 - Reprappers
Re: Nozzle size ? - 11 years ago
Has anyone tried printing with a larger nozzle size, say 0.8 or 1mm? I usually go for functional parts only and If I could print a more robust part that would be a bonus. Also my printer sits for long periods and I really want a printer that I can just turn on and print with minimal tuning.by martinprice2004 - Reprappers
Re: attaching threaded rod to idler bearing ? - 11 years ago
There are two main reasons why idler bearings can be trouble. The first is that the threaded bar is never straight and when you constrain it even further with an idler the Z wobble becomes worse as it cannot float about. It was a major failing of my early delta robot and a reason why the Rostock with belt drive performed so much better. In addition, if you measure the major diameter of the 10mmby martinprice2004 - Mechanics
Re: 3d printing using paper - 11 years ago
Thinking out aloud here, but LOM tends to be very wasteful of material, so I was thinking of whether there would be a way to produce thin strips of plastic sheet (sort of like a pasta machine through rollers). The machine could then recycle its left over material back into useful sheet. My first thoughts are a three stage machine, one that produces a sheet feeding across to a cutting head and thby martinprice2004 - General

Re: Bre Pettis does Mazda ads. - 11 years ago
I am very surprised that no one has thought of taking the 3D model of Bre Pettis's head and grafting a large male member on the forehead. We could then all re post it back on Thingiverse. It just seems the logical next progression to me and much more creative than posting cubes on there. .....I welcome other suggestions of how to show our disapproval.by martinprice2004 - General

Re: crowdfunding an Hot Wire polystyren cutting CNC machine - 11 years ago
Is there any way you can dope polystyrene or similar material with something to make it hard and strong? I am thinking you could cut a reprap frame on one of those and then paint it or dip it in something to make it hard and rigid. Perhaps a more open structure foam (Like Oasis floral foam) would be more suitable as this would take a strengthening resin more easily. This would make mass producby martinprice2004 - CNC Routers, Mills, and Hybrid RepRapping

Re: Printable PCB Mill - 11 years ago
This is a good idea to develop one of these machines, particularly if it was capable of cutting steel as well as PCB. Your design is probably not the best configuration for a milling machine though. The part bed should be fixed and the head move in all axes. There are several benefits for this. 1) The machine footprint is much smaller for the same sized workpiece. 2) You get natural damping whenby martinprice2004 - CNC Routers, Mills, and Hybrid RepRapping
Re: repositories - 11 years ago
Every single .stl file I pull from thingiverse doesn't load correctly into any CAD package I own. There is a scaling error (metric / imperial) and also there are many non manifold surfaces. I take the .stl file and load it into Blender 3D then export it back out as .stl. This overcomes the binary/ascii issue. I then use a piece of software stl to igs and then import it to my CAD system.

Re: Looks like an interesting option for electronics - 11 years ago
Yes just spotted this myself. Its basically an arduino with the ability to run linux / android and and a full hdmi screen like a raspberry pi. A reprap with this power, you could just send it your cad file and it could print it directly. The only thing is they seem to be putting too much in and hence the price might put some people off. It needs to be about £50 all in.by martinprice2004 - General

Re: Awesome new 3D Printer - J-Rev - 11 years ago
The form1 machine would be capable of producing an Eiffel tower. Its a stereo lithography machine. It could easily be produced in two parts. Kickstarter rules forbid renders or photoshop images to advertise a product. You must demonstrate a working version of the item doing what you claim. It seems that Japica didn't even read kickstarter rules. I guess Kickstarter got "Japicad" as well!by martinprice2004 - General
Re: Awesome new 3D Printer - J-Rev - 11 years ago
Perhaps in memory of this complete fiasco of a design we should create a new verb or noun to help us describe projects in the reprap community.

Re: Awesome new 3D Printer - J-Rev - 11 years ago
1) It will be difficult for you to get your Z axis to be as accurate as a conventional vertical linear rail. Two concentric bearing interfaces are not as accurate as one. This is just basic physics. Using 3D printed components for these parts makes things even worse. The part you claim to have printed (The Eiffel Tower) is a hard print to pull off with such a clean print as you have shown with noby martinprice2004 - General
Re: 3d printed ultralight airship - 11 years ago
I have been wanting to create a carbon bike frame for a while now and have been looking for a way to utilize my reprap to save foam sanding. Trouble is I only want one bike not a production run, so making a mould is not really necessary. I think it could be used for RC planes. Use expanded foam over a carbon fibre centre spar. I imagine this technique could also be useful for large items built fby martinprice2004 - Let's design something! (I've got an idea ...)
Re: 3d printed ultralight airship - 11 years ago
Sorry to raise an old post, but thinking it through further there may be a way to produce light structures more simply. 1) Print a mould (mold) using a reprap. You could do this in sections for a large item such as a wing or airship hull and bolt them together or mount them to a wooden board. You could also position spars and reinforcement such as cardboard tube in the mould or smaller reprappedby martinprice2004 - Let's design something! (I've got an idea ...)
Re: Have you made anything useful? - 11 years ago
The bike pedal is nice. Many like me were unconvinced of the strength of printed parts. I think this is mainly because we tend to print them with reduced % infill. I printed a pair of adapter brackets for my rear bike carriage. 100% infill makes very strong functional parts. They haven't failed yet after 8 months.by martinprice2004 - General
