Yeah depends on which part of the software toolchain you're talking about to do the 3d modelling, pretty much anything you find comfortable working in will work. from there you need to convert it to an .stl file if you're lucky your favorate 3d modelling program will do this or have a plugin to do this. after that you need to slice it, I'd recommend slic3r to start with, though there's also sfacby se5a - General
The normal ones will be cheapest, but it would be very handy to have some -maybe half? of them nylocks (your second link) nylocks wont unscrew by themselves but you can still adjust them easily enough with a spanner, on the other hand they can be a real pain if you want to put them in the middle of the threaded rod (they are hard to screw, even with a spanner) I ended up using normal nuts with loby se5a - General

why does the PTFE fail? would the glass mixed stuff work better? I've found a place here that does different grades/mixes of PTFE and glass, wondering if the glass stuff would work better.by se5a - General
The biggest thing when buying steppers is to look for how much torque they have vs how much current they use. kthx says: ideal steppers are NEMA17 size, rated 1.5A to 1.8A or less, 1-4 volts, 3 to 8 mH, 62oz.in (44Ncm, 4.4kg.cm) or more of torque, 1.8 or 0.9 degrees per step (200/400 steps/rev respectively), for example the kysan 1124090/42BYGH4803 or the 17HS8401 I've just ordered some of theseby se5a - General

I'm a last 6 months repraper I've built a prussa, I went with the prussa because it seemed most popular I went with ramps because it had the extra extruder capability. - got as a kit and soldered up. didn't have any problem with that, except for that diode not being too clear. the stepper motors I chose are not ideal and overheat, I went with them because they were what was easily available whereby se5a - General
natural PLA is supposed to burn away without leaving any residue. I'm keen to see if it works well for lost foam type casting.by se5a - General
this has pretty massive implications in nano tech. once we can make reliably make electronics and motors that small as well...by se5a - General
You will need an arduino mega as well, since the RAMPS board plugs into the arduino. you'll also need some pololu steeper drivers to plug into the rampsby se5a - General
if you make a mark on your filament at the top of the extruder, then reverse it out, you should be able to make a farly good estimate at where the glass transition point is right? you might have to allow for a little bit of stretching, but it should give you a fairly good idea. we need to put all this stuff on the wiki with good diagrams and calculations.by se5a - General
if you're only doing PLA you can get away with not having a heated bed. but you'll have to limit the size of anything you print or it'll warp. the difference between threaded rod and smooth rod is that threaded rod is threaded and smooth is smooth. you cant run bearings along threaded rod, and you can't screw nuts on smooth rod.by se5a - General
Except you failed at manually installing a device driver in XP. you may have the exact same problem with any other electronics. you really should learn how to do this. in my day we had to install all drivers this way we also walked to school barefoot uphill both ways in the snow Edit: I can show you how to do this if you like the easiest way would be to use teamviewer, but that would require youby se5a - General
only seems to do the first layer as the different pattern. ie: I was using concentric solid fill pattern with rectilinear fill pattern. the first layer was concentric, the second ( also a solid layer) was rectilinear, all other solid layers after were rectilinear also.by se5a - Slic3r
what is it that's normally 'broken' with STL files? what can I do when designing my models to improve them? I loaded the pre netfabb and post netfabb stl files in metasoqua and the only real difference I could see was that netfabb had split some of the larger triangles again.by se5a - General

what's your toolchain and why? I'm currently messing with: metaseqoia with an STL plugin, -> STL thoguh then -> Slic3r -> pronterface -> sprinter. metaseq: because I know how to use it, it's simple, with a straight foward interface and doesn't hide what you want to do behind a bunch of confusing menus. I've tried others and just can't seem to get my head around them. when exportiby se5a - General

From what I understand the bigest problem with recycling plastic bottles is that hdpe (which is what most plastic bottles are made of) shrinks a lot so it's tricky to print without warpage. nophead I think has experimented with it a bit, I recall reading about it somewhere on his blog:by se5a - New Zealand RepRap User Group

main difference? Show me a CNC model/design that DOES replicate. yeah sure they probilby can, but RepRap was designed to do so, and there's talk of starting a familiy tree type project to map who made who's parts. show me a cnc machine that has that. in a nutshell, I guess your answer is: the comunity.by se5a - General
1) PCIe is 12v and if you need the power of another rail just do what the high end graphics cards do and have another molex. 2) I wasn't the OP the other two may be good points though.by se5a - General
how hard would it be to put everything on a PCIe card?by se5a - General
Good catch, I can imagen how something like that could be easly overlooked, I'd expect a thin layer of wax to cause a huge difference to stickyness. (or lack thereof)by se5a - General
