I should clarify, because reading my post again now it isn't very clear, but the breaking of the coupling was completely my fault - I was putting too much pressure on the entire x carriage as I was trying to push through some blocked filament by hand (I know, I know, i've learned a lesson in patience now).
So far the Z axis has been holding out well for me (touch wood!) apart from a slight wobbl

I agree with owism8. I'm all for making reprap accessible for newcomers, and if a book would help some people then great, but the project is moving pretty fast (which is a good thing), and I think something static, like a printed book, would be outdated very quickly.
If you're doing it for personal gain, or simply because you feel like doing it, then go for it and good luck! If you want to con

That could be very useful. Thanks!

Good find! I've only spent 5 minutes playing so far but it seems it could be useful for knocking together quick parts and such.
Btw - if you have Windows XP and Google Chrome you need to add the following flag to your startup command: "--ignore-gpu-blacklist". may save some people having to click through to the answer

Thanks for the advice guys.
I had already taken a stab at configuring Skeinforge after finding the discussion brnrd mentioned but I had only measured the amount of filament using 10mm lengths. Tonight I started from scratch using 100mm and found my initial e-steps was too low (539) and should be around 610. I also reduced the flow and feed rates right down (30/30 to 15/15), and even then the f

Hi Everyone,
I'm having difficulty producing a usable pulley for my Prusa Mendel with a 0.5mm nozzle, and would like to ask if anyone has any special tips?
I have tried the standard pulley STL that comes with the Prusa, the modified version in Prusa's folder (pulleymod.stl), plus a modified version of the original by Greg Frost. The results are either warped spurs, or the spurs are too large t

I agree, and I also think the General FAQ should be there too (and it should be renamed to "General Introduction" as it doesn't contain any questions!).
Perhaps it would help if there was a real FAQ, in the style of "What is a toolchain?", "Where can I learn skeinforge?" and such, divided up under sections such as firmware, electronics, hardware etc. Probably each answer would lead to a wiki p

Hi Michael,
Just to elaborate on Bob's answer (I wrote this without noticing the updates already written, d'oh!) ....
Skeinforge (the program that converts your 3D model to instructions for the mendel) has a module called "statistic". You set the parameters you need (filament size, layer height, etc), create the corresponding gcode file, and if the statistics module is turned on you get a rund

Hi John,
I agree that it can be a bit overwhelming/confusing for those new to the reprap world (I only built my Mendel a few weeks ago, so it's still a bit fresh in my mind), and it would be useful to have a few more resources geared towards those with little prior experience. (That's one of the reasons I put together the Prusa Mendel Visual Instructions).
I also think there is a need for a re

That's really interesting to watch! Excuse my ignorance, but what surface is causing the reflection?
And of course I have to ask - where can we find the plans for the hot end? I'm about to build my next attempt and am open to new ideas.

Open Office Impress would also work. I only used Publisher because it has been laying around unused on my PC since I got it, you can position the images nicely, and it generates the PDFs quite easily.
As Sebastien has mentioned, using the wiki would be best, because it's open nature reflects the requirements we have for documenting (I guess): open, accessible, easy to use. I also think it has t

Hi Sebastien,
I'll happily upload the images into the Wiki as I agree that it's better to have it in a central place - I didn't want to spam the wiki whilst i'm still a n00b
Would it be best to create a sub page for the images (there's quite a lot of them) or adding thumbnails (or a text link saying "see image") alongside each step? I don't want it to distract from the flow of the page.

As I was learning to use Google SketchUp, and building my Prusa, I put together an instruction manual for the steps, loosely in the style of a Lego or Meccano guide. There's some more details in this blog post, and the document can be found here: http://garyhodgson.com/reprap/prusa-mendel-visual-instructions
Whilst the steps in the Wiki are clear and straight-forward I thought this could perhap

Hi Cefiar, thanks for the detailed response - it really helps to be given pointers like this.
I suspect at some point I disconnected the motor from the RAMPS board without turning off the power, so it could be one controller lost in the name of learning. I'll test a new one and be more careful in future.
The Pololu's were set to a quarter turn, so I can try increasing that. The power supply

Hi,
I'm in the middle of building a Mendel Prusa and currently trying to test the electronics - with which i'm having mixed results. I suspect I may have blown some components whilst testing the end-stop micro switches, and would like some advice on whether what I did was completely wrong, or whether the problem could lay somewhere else. Any hints or pointers would be appreciated.
So, it's a
