QuoteThorp I noticed that a good set of mendel parts is going for over $400 on ebay. Why are more people not printing out sets and selling them? Probably because it takes several tens of hours to print a set (I've seen time estimates of 60 to 120 hours), and most people with working Repraps do not risk leaving their RepRaps printing unattended. And there is risk to your Reprap every time you prby jmarsden - Reprappers

If you don't see the post-processed lasercut parts at BotMill, try at TechZoneCom.com instead. TechZone are the folks who did the technical work behind the products that BotMill sells. It looks to me as though http://techzonecom.com/detail.php?pr_id=12 is what you are looking for.

My pin has stayed put since December of 2007... although I do see several others in mid-ocean locations, which seem unlikely to be valid... perhaps mine is not considered worth vandalizing?? Zooming out (using the scroll wheel of the mouse is the easy way to zoom in and out) lets me see the whole earth at once, which currently shows all pins -- we do not yet have any Reprappers in orbit, or on Mby jmarsden - Reprappers
The reprap.org host software is in Java. The firmware for Arduino is in "sort-of-mostly" C++ (Arduino uses an IDE that wraps C++ up in a bunch of non-standard libraries and a default main() function, and sort of tries to hide that, so it looks "easy" for beginners). The less official host software ... Skeinforge is in Python. Repsnapper is in a mix of C and C++ from what I have seen (and seemsby jmarsden - General
OK. You can do plenty of highly relevant and helpful "learning by doing" without any reprap-specific hardware, just a PC... learn the Reprap host software; learn the Arduino IDE and programming language/libraries, if you want to do firmware changes, learn (multiple) 3D CAD programs (FreeCAD, OpenSCAD, HeeksCAD) and mesh modellers (AoI, Blender, ...) , etc. You can do all that with just a PC andby jmarsden - General

Looking over my earlier response, and multiple AWG charts, 22AWG wire should be fine throughout, and is what most of the connectors involved work well with, so that's probably the way to go. (If you upgrade to a heated bed later, a popular modification which can draw a LOT of power, you'd want to use beefier wiring for that, obviously.)by jmarsden - Controllers

Could I suggest that when asking questions about specific parts, you include clickable links to the parts in the Mouser (I'm guessing Mouser UK?) online catalog, that you are considering, or at least the Mouser part numbers, so that anyone wishing to help you can fairly quickly check them out for you? These connectors should not be a pound each! Also, it sounds like you would benefit from hookiby jmarsden - Controllers

RepRap is an open source system, and aims to be both usable and modifiable using open source tools, so there is no hidden financial cost to being able to join the RepRap community and help to improve it, and so that the removal of a proprietary product from the market can never be a roadblock preventing the project from continuing in the future.

Talking face to face with the TechZone folks at the San Mateo Maker Faire a few weeks ago, the soldering quality control issues you mention were known, Seb (and someone else, I forget who) asked about this, and they have been acknowledged and addressed.

Has anyone printed a set of Isaac parts using an Isaac (or using a small huddle of Isaacs in parallel)?
