I added the step line just to try to encourage some variantion. Its just that without something like that you just end up with 5 different versions of (prusa) mendel with only small changes. As for the documention line i mean builds with overview, bom, build guide and troubleshooting/tweaking pages. Or atleast the first 3 (hence the 75% i posted). This was just to avoid having machines on the frby JoeDaStudd - General
I like the idea of including more builds on the main page. However im not too keen on having the smaller variants on there. Something like ;prusa mendel, mendel, huxley, wallance and darwin (imo its nice having the original reprap on there). The other prusa based machines just make it more confusing for a newbie. Guide line wise something like: *must have full or at least 75% complete documentaby JoeDaStudd - General
The trouble is the Raspberry Pi only has a single serial port spare. So you wouldn't have enough i/o ports to directly use RAMPS or any other solution without a micro-controller (well as far as I'm aware).by JoeDaStudd - Controllers
Which hole is 1.75mm? It its the output hole the prints would be very bulky, 0.5mm (nearly a 1/4 of the size) is the standard starting nozzle size with 0.3mm and lower being increasingly popular.by JoeDaStudd - Reprappers
1.75mm requires less torque to extrude (less pressure). Thats really the only major difference in terms of performance. However depending on your location it might be easier to get 1.75mm or 3mm filament. Ps. Its the nozzle diameter which affects resolution.by JoeDaStudd - Reprappers
Personally I'd say RAMPS would the best if you want to be able to use the Mega (1280 or 2560) board for multiple applications. You could reuse the chips from Sanguinololu and possibly some of the Gen x models, but you'd also need to strip down the usb components or buy/build a circuit which has, in order to make use of the chip. Most of the Gen x boards also have intergrated stepper drivers whby JoeDaStudd - Controllers
Good point. The advantage of the Pi is its about the same size as RAMPS (without the mega), runs off 3.5W, silent and costs about £25 for the full version. I was planning on buying one as soon as they are out to run xbmc and hopefully another to tinker with. I just figuired if it could run xmbc and some of the other apps they demo'd it would be too much slower then using a conventional pc. Iby JoeDaStudd - Controllers
The Raspberry Pi (model is due to be released in the next few days/weeks I was wondering if anyone had ARM binaries for any of the RepRap host and slicing software? If they are or they can be compiled then I could see it being an awesome addition to any RepRap setup. I'm thinking hook it up to the electronics via usb, attach to a router via ethernet and power on, then just remotely push filesby JoeDaStudd - Controllers
@Quentin.T Download the software from here. Once you load the software its pretty straight forward from there.by JoeDaStudd - Reprappers
From the RAMPs 1.4 wiki page under Wiring (link). Ps incase your wondering COM on the psu is ground.by JoeDaStudd - General
If your buying from Zapp I would recommend buying these. Nearly double the torque of the one you link at only £1 more.by JoeDaStudd - Reprappers
The defination of vitamins in regards to RepRap is the parts you can't print making the question an oxymoron With a small nozzle and a well calibrated machine I'm sure you could print the larger nuts or screws. However they wouldn't be as strong, as cheap or as uniformed plus they'd need a lot of cleaning and take a while to print. Overtime more and more parts are becoming printed parts, but tby JoeDaStudd - General
Is that a general list or just the electronics? If its electronics you missed the stepper motors (x5), 2 endstops (you need 3 in total) and the cables/connectors for this parts. If its the general list you missed all of the above as well as printed parts, hardware (all the nuts, bolts, rods, etc), hot end (inc wires + heating element) and print bed(s).by JoeDaStudd - Reprappers
The standard stepper drivers (pololu's and stepsticks) won't reach 2a, I think nophead or someone said around 1a is the max you actually get. You should be able to power the nema 23's with standard drivers however you'd only be getting about a 1/3 of the rated torque.by JoeDaStudd - Reprappers
The stepstick you brought has trimpots without any stops/ends. You need to calculate the resistance/voltage using a multimeter. I noticed this when I came to set the trimpot to zero/home (or whatever you want to call it) it just kept turning. I contacted snipermand who confirmed they don't have any stops. You can read the values by attaching a multimeter to highlighted points. I didn't checkby JoeDaStudd - Reprappers
I think part of the issue is the fact none of the options have any real pay back as such. If you did say $200 gets you a full set of plastics for a prusa or even a few sets of brushings for a few $ you'd get some backersby JoeDaStudd - General
There are quite a few different variations and a few videos about attaching a pen/pencil to a RepRap.by JoeDaStudd - General
It happens when the layers cool at different rates or suddenly. A heated bed will help solve the issue.by JoeDaStudd - General
Greg Frost was selling complete (assembled, configured and calibrated) Prusas ,with all the bells and whistles you could want ,in Australia for $1400+ shipping (link). But he sold out today . Its worth dropping him a PM to see if he has any kits going though.by JoeDaStudd - General
I'm fairly new to this, but most of the answers I can help with. 1. Check out Most RepRapper's like to share there designs and upload them there so it will give you a idea of the range of item being created. 2. Another link Comparison posts are added every now and then (this is one of the best comparisons). 3. All the plastics you see on any of the RepRap's. Not sure on the exact percentageby JoeDaStudd - Reprappers
If they have no load (well pressure) they shouldn't require much current to turn. Are all the motors doing the same or just one?by JoeDaStudd - RAMPS Electronics
Check there are no solder bridges on the RAMPS board. I had a similar issue on my Z-axis a hair sized piece of solder was bridging one of the headers. If you can't find any its worth double checking the colours -> pin setup is correct for your stepper motors as they can vary make to make.by JoeDaStudd - RAMPS Electronics
If the test code doesn't run correctly then something is either shorting or is broken. Disconnect everything then run the test code again. If all 4 LED's don't flash then its the board itself. If they all flash with the test code then one by one attach each part until something doesn't work (make sure its powered off when your connecting or removing parts).by JoeDaStudd - RAMPS Electronics
You do understand there is a far bit of calibration required once you have the RepRap built right? You don't get the quality of prints you see on Thingiverse or various blogs from the off.by JoeDaStudd - General
I found the sourcing (reliable suppliers) and the electronics (I choose a DIY kit...) to be the more tricky parts. I have pretty much zero engineering experience (I've tinkered with lego, k'nex and meccano but thats about it). Looking back if I had all the tools, parts and pre-assembled electronics I needed from the start I could have gotten by build to print stage within about 4 evenings or 1by JoeDaStudd - Reprappers
Nice idea. Something like fly fishing line would be better though as its far thicker. However upon doing a little research it appears they have a pvc coating which isn't ideal.by JoeDaStudd - General
Cheers, I'll give it a go tonight. Its a slightly different layout to the ones you sell (I brought the full RAMPS DIY kit from you a while back).by JoeDaStudd - Controllers
Hi, I brought this stepstick. I soldered the legs then attached it to my RAMPS. After powering up and running the test code there is no movement. So I went to adjust the trimpot (that is the correct name for it right), counter clockwise until it locks then clockwise 25%. The only trouble is the trimpot never locks or stops. I contacted the supplier and got this response. There are no stops toby JoeDaStudd - Controllers
Love the idea, especially the 2 Z-Axis outputs. Just a thought, wouldn't it be wise to move LED 2 to 4. They look like they are almost directly beneath the wires. This would make them hard to see and potentially lead to them being shorted by a lose wire.by JoeDaStudd - Controllers
I think the whole pre-assembled thing was down to me I saw the $2000 target and presumed you'd raised ~$500 for the project already.by JoeDaStudd - General
