Try Arduino 17 to see if that works
I have not tried Arduino 18, nor did I know it was released, so try the older version first.

RepRap Host
I remember a couple of tore ideas.
1. All non replicatable must be able to be made without the need for special equipment like a lathe. A drill press and bits, vice are a couple of examples of tools which are easy to come by.
2. To be able to demonstate that the printer can swap tools by itself.
3. Demonstrate it can use all 4 tools in a single build.
The fourth tool being a light drill for

Kartik M. Gada Humanitarian Innovation Prize
Quoted here to start things off.
The winner of the PM interim prize will be the inventor who can make a 3-D printer that can demonstrate the following:
* Print at least three different materials, including one that is usefully electrically conductive.
* The ability to print electronic circuit boards.
* Print beds†must be of a material which may be reused with minimal refurbishment

I just spent several hours last night to hunt for information on how to program a virgin Atmel 644p with a bootloader that accepts the Arduino IDE.
If like me you program a virgin chip right off from Arduino IDE, it may likely fail.
I use the USBtiny from Adafruit
I also downloaded the latest version of AVRdude that comes with WinAVR, as it has the support for the 644p.
I had to use AVRdude a

I may have made a mistake when I put those wires on.
They were going from the motherboard I2C to the extruder board I2C, they should've gone to the D9 and D10 inputs on the extruder board.
Will check this out soon.

Hello everyone,
I have got the Generation 3 electronics, ie V1.2 motherboard, V2.2 Extruder board, and 3 V2.3 stepper drivers.
Using the latest released RepRap firmware in both boards. and also using the latest host software (August last year).
Everything works except the extruder stepper. I know the COMS are working because I can turn the heater on and off. I can also read the heater temperat

We should stop using AoI as it is so bugged, it cannot be opened if Java 6 is on your machine.
Blender however is continually being updated with frequent updates during the year, and runs on any machine, so my suggestion, scrap AoI for the open source method and begin using Blender.

It shouldn't need to be something we automate, we should be able to use any sized Spur Gear or splined sleeve we like and adjust the bearing close to it, then

Great idea, I may actually buy them from these guys and ship them to NZ, depending how much I can get them from my local supplier.
Thanks so much

The pins that are giving issues are
H1D1
H1E1
H2D2
H2E2
Which are not timer pins, and are also not ADC input capable either.
I've got to take my extruder board into work to replace an LED, and to check other things, but in any case the other should light up when its working, regardless if a motor is connected or not, and I do have one connected.

Best to buzz Vik Olliver in Auckland, he gp usually forgetful, so you need to keep bugging him.
I live in Auckland, and am a member of the RoboNz group. i love robots so i'm building a RepStrap, but once i'm actually printing parts out, i'll be flogging Mendel parts off on TradeMe.
At some point Tim Carr from MindKits.co.nz will have an official inventory of Mendel bits for us Kiwis

Actually, with so many sub forums around now, its getting a lot harder to keep track.
If the forum were collapseable and expaded when needed, that would be very helpful.
I'm one of those people that browse the web, read and write to specific forums when they are at work, on their mobile phone.

I think I have found the problem, I ran some test code to turn on some leds, and it looks like my Arduino has some slightly half dead pins.
Whether it is from static or from back EMF from the MakerBot firmware, I dunno, so i'll have to get a couple from Farnell, as they are the closest supplier to me with stock, and i'll replace my Atmega 644 20PU (DIP) with another tqfp, as the once I had put o

Whoops, I got a little distracted watching the large MakerBot blog video, then jumped onto YouTube to find a good video and found lots, of musical Tesla coil action.
Modifed that bit of code, won't compile, will have to comment it out.

RepRap Host
Looking through the firmware code while i'm at work on tea break, I see that M101 and M101 have been commented out with a note saying that its been replaced by E codes, not implemented by the look of it.
Another note says that M126 and M127 is now how the extruder gp controlled.
I'm just so confused, and it wont work.
My thought is that i'll uncomment the M101 and give it a shot when I get home

I have Gen3 electronics, ie a V1.2 mobo, V2.2 extruder and 3 V2.3 stepper drivers.
The plan is once I have it all going, in some partial way, I can change the firmware to use an encoder and use that to step the DC extruder.
At the moment, the extruder driver isn't even being turned on, even if I had a stepper pinch extruder, it wouldn't work anyway.
