Tony: Your issue seems to be rather different from the one blcArmadillo was having. So you will probably get better results posting as a new topic, rather than asking your question in the middle of this thread.

The problem is this version doesn’t support the Master Slave configuration I purchased from Makerbot.

The wiki instructions for uploading firmware to an extruder board should work - USB cable to extruder board.
Also, when reporting issues, it is often more helpful to say what *did* happen when you tried something, rather than just "it didn't work". What exactly did you do when you hooked up the extruder board to your host computer via USB and ran the Arduino development IDE? Did the power LED

dissidence: It's now relatively straightforward to design, and then either make yourself, or ask BatchPCB or similar places to manufacture, a PCB (or even a few PCBs), rather than using a protoboard-style shield for your work. So you do not have to be constrained by available prototyping shield layouts.
And yes, please do document your work, (preferably on the reprap.org wiki), so that others ca

Which jumper? The only one I can see in the PCB_adaptions_for_Mendel wiki page about adapting the motherboard for Mendel is the one that goes between the USB-Serial connector and the ICPS connector. This *is* so 5V will get everywhere it needs to, the wiki page itself says:

Pololu Electronics Thoughts:
Pros:
+ Lower cost
+ Easily replaced when one dies
+ Under active development within core team and elsewhere
Cons:
- Are a less official experimental alternative
- Cooling may be an issue (small chip, hard to heatsink well)
- Used with an Arduino Mega, currently need forked firmware
I'm just starting to attempt a Mega + Pololu approach myself, BTW, probab

Based on my reading of the svn logs and the core team mailing list, at the moment there is more happening within the team regarding using the little Pololu stepper driver boards and their A4983 chips, than with the "V3.0" boards proposed by Zach. I suspect this may be because Zach has got very busy with Makerbot. I don't think the "V3.0" stepper driver board design files are in the reprap.org s

I've prompted Adrian to create us a BOM (Bill of Materials) for his circuit design as soon as he can.
Meanwhile: You want components rated at a somewhat higher voltage than you plan on using (as long as they physically fit the design, and are not too expensive!). So that means capacitors rated *over* 12V in this case. Something like Mouser Part 140-RGA101M1EBK0611P should be fine for the 100uF

Thanks for finding that! I just linked to it from Adrian's Pololu_Electronics wiki page, so it is now (hopefully!) a bit easier to find, for others looking into Mega-based electronics.

QuoteTiberius... there still should be a "official" set of electronics for the reprap project so that it is clear which electronics will work with the standard firmware.
RepRap doesn't do "official". The ones in the RepRap project svn tree for Mendel are as close as you will get. That is, the "Gen 3" electronics are currently as "official" as you can get in this community. They work with the

Do you have any idea what max current might be usable with the Pololu boards in Adrian's proposed "wind tunnel" configuration? See http://reprap.org/wiki/Pololu_Electronics and the recently checked in related parts:

General Mendel Topics
The power adapter you linked to says it is a "72-Watt 12V 6A AC Power Adapter".
It is unclear whether the "AC" in that description refers to its input, or its output! If it really does output 12V 6A AC, then it is not what you need for as Reprap, which needs 12V DC. However, trying to read the image of its label, there does seem to be an indication that the output is center positive... which m

QuoteSimonRaffertyIf you download Adrian's latest version of the host software from Sourceforge as well as the latest 5D firmware and extruder driver - it all hangs together pretty well.
Interesting info, thanks. It sounds like we should perhaps make a new release on SourceForge, so that folks who find using the .zip file releases easier than using svn can use it?

I'm a core team member (since 2007, though I've been quiet/absent for a long time!), so I can get a full set of RP parts (direct from Adrian) including either extruder design, which is wonderful.
Assuming obtaining extruder RP parts is a non-issue, do you still see significant differences in the tools or skills needed to assemble Adrian's and Wade's geared extruders? If so, can you describe tho

If you can let us know exactly which schematic file(s) from where in the Reprap svn tree you are having problems reading/opening, that would help others to help you.
The current Reprap Mendel "Gen3" electronics were designed using Eagle, not Geda, as far as I know. There is work under way by Nick McCoyn to create a set of electronics design files using Geda, but that's a single board design, so

There are others working on alternative electronics (and, I think, even alternative microcontrollers too).
I believe that "Gen4" was Zach's designation, and refers to his work. The whole "Generation N+1" concept is difficult to apply well in a fluid development environment, where several people or groups of people may be working to enhance or modify designs of one subsys

I support the idea that differentiating the official (self-replicating)
project from other offshoot designs would be very helpful, and that
distinction has been lost, as others have pointed out.
I too disliked the huge number of forums, but I think the approach of
forums that are very generic (like "Electronics" and "Mechanics") goes
too far the other way, since there *are* now offshoot desi

For now just post under an appropriate forum for whatever subsystem is being documented.
Better yet: ask Zach for Wiki write access and *edit* the documentation directly to fix the problem :-)

Then, reinstall Compiz, and document exactly what

too vague to be easily replicated or debugged :-)
