I like everything, but the price is a little to high and the number of stepper motors it can drive - too. I generally may need five at most. Running stepper motors in parallel had always worked for me if one axis required two motors. Maybe you should make a budget version that would try to compete with the LPT drivers and make a more expensive version? What software is everything going to be coby Tarakan - Developers
Ok. I got a question. For economic reasons I want to own a CNC machine that can do both, 3D printing and milling. I will buy some existing frame for this purpose. I have a spindle motor. So if I use Mach3 and LPT port, I will be able to buy a cheap CNC mill and set everything up very easily. However I will have to use an old desktop that I have around. I will probably have to rely on old technolby Tarakan - Developers
Has anyone thought of refining the precision of the 3D printing to the point when dentures can be printed very chaply? Sounds like a great philanthropic mission. I would set my goal that if I find all the appropriate materials tools to design a cheap 3D printer that will give the right surface finish, I will work on printing dentures with non-toxic plastics.

I feel like I don't want to mess with it. Chances are that I won't be very good with it working alone. This is what happened when I tried to make PIC USB device in the past. It worked but I learned the wrong software and got bad results. I am wondering what will happen if I use teensy USB? Otherwise I would use software like Mach3 and a parallel port configuration. I need to know what the USB dby Tarakan - Developers
I just thought that using a stepper motor - timing belt - turntable configuration is a bad idea. Because hot plastic will create drag, the table will oscillate as it vibrates, causing uneven hot plastic distribution. I would prefer to use two gears - one for the motor and a really large one for the table. It this a good idea?by Tarakan - General
I am not using anything. I feel like instead of paying for filament we are going to pay for shredder blades now... Maybe there is a way to compress plastics against a hot surface? I feel like it is a good idea to do if you are planning to make a small factory out of this. But desktop filament maker would consume too much power/blades/time or everything at once, making it pointless. Maybe RepRapby Tarakan - General

Is there any way you can convert it to simplified 3D objects with solid guts? To make things cheap, I would make hollow openings inside but I would make them cylindrical.by Tarakan - General
So the development of this device is completely decentralized. There is no laboratory, no funded part, no dedicated machine shops? Than who develops electronics? I feel like if I would come up with improvements here, I will struggle because I am not very skilled in microcontroller programming. When I start any serious development project, I try to get as close to the real people as I can get. Woby Tarakan - Developers

My thoughts on building an additive lathe started when I decided to replicate one of Viktor Schauberger designs with water. I was thinking about the price of machining and realized 3D printing is a better idea than turning things on a lathe. Would this work as a base? I want to design such device so the turntable will slide on an axis and an extruder will slide over an axis above the table. Tby Tarakan - General
I would like to reach to those people. My linear drive idea is very refined, honed out and economically justified. I spent a long time thinking about it. Almost failed my high school freshman year!!!

Is anybody interested in revisiting the additive lathe project?by Tarakan - General
I had built a very similar design at one point. A linear drive used two coils that had C-shaped laminated cores. Both ends of the core were employed in the process when a coil was energized... I used ready-made junk parts. My machine crawled across a 2D table. A permanent magnet held it flush to the surface of the glass. Soft iron stock cubes were used to attract electromagnets.

I am very interested in this topic. What kinds of plastics or blends give the best result? Do they smell bad? Do they clog the nozzle? How do you shred the plastics in preparation for melting? I tried to cast molten plastics when I was little and I am curious about the results you are getting. I poured molten plastic from an elevated surface of a bridge under construction into a creek.

OK I will. I still do feel a little bit uneasy about letting go of my ideas because I am an underemployed delivery truck driver... 1) To make an additive lathe. In a way it is like a pottery wheel with a head stock-like device that the project is going to be layered onto. An extruder would be movable towards and away from the center of the spindle.

Is it possible to use induction heating to heat both the nozzle and the bed to the right temperature? I have some ideas about this, but I lack resources to test them. I feel like inductance heating is the future of both, the heads and heated beds. Another way to heat a bed cheaply would be to get a piece of flat material and to wind nichrome wire under it in some zigzag fashion and glue it inby Tarakan - Developers
Hello. I live in a small town, in Frederick MD, USA. I would like to contribute some ideas to the RepRap development. I have an idea that can allow a very cheap and precise drive mechanism for a 3D printer. It was tested but for different applications. I have one idea that may allow 3D printers to assemble SMD electronics, almost without any modifications. I know that there is a lot of researby Tarakan - Developers
Hello. I want to learn how to program Arduino microcontroller. I know some C programing language, no Assembly. I never made projects that were complex enough for C++. I have a hard time using Assembly because it makes me think of reinventing the wheel sometimes. I write a code that is already a part of some C command.
