The project is alive and kicking:
We release development snapshots regularly, but stable releases are quite a bit farther between.
Join the mailing list/forum or post github issues for bugs:
Note: We don't have any funding so development is done by a few people on our spare time. The best way of getting improvements is to write code

OpenSCAD
Hi Steve,
OpenSCAD is gradually improving - we're currently looking at tessellation quality and it would be interesting to see the original model causing the issues you mention. Since you wrote your original message, lots of fixes has gone into OpenSCAD, so this might actually be less of a problem now. Anyway, if you have any offending models lying around, I'd be happy to take a look at them.

This is exactly what the MakerBot firmware does.
All the magic is on the computer side (i.e. in Skeinforge and ReplicatorG).
I don't quite see where STEP fits into this

Hi again,
I think I found a small bug:
If I activate both towering and multiply, the head crashes down into the recently printed layers of one object before moving to the next object.
A very simple way to reproduce this is to use this model and just activate tower and multiply. I used a 5-layer tower and a 2x2 multply:

Hi Enrique,
Just a small note: Some files appear to be missing in svn; at least home.py and preface.py.

We also had some issues with 2.7.2 being less stable than 2.7 wrt. boolean operations. Otoh, 2.7.2 evaluates the boolean objects significantly faster.
I haven't pinpointed the problem yet, but if someone manages to isolate this problem to a simple test model and submit it to the Art of Illusion team it would be awesome!

It looks like they didn't actually open-source anything, they just released the specification for the OpenSBP description language.
I might be wrong, but I peeked around and only found Windows binaries of their tools.

Yeah, parallel ports appear to use 5V (TTL) logic.
I measured the signals from the PC connected to the CNC using an oscilloscope, mapped this to Arduino ports (basically the same ports as the stepper drivers normally would use), and soldered together an Arduino shield from a protoboard where the parallel cable can be connected.
It worked without problems on the first try

Hi,
We also use a CNC machine with an extruder attached.
The CNC controller is usually hooked up to a computer using the parallel port.
We solved this by connecting the parallel cable from the CNC controller directly to the Arduino running the normal reprap GCode firmware.

In GCode_Interpreter.pde, change this line:
#include "WProgram.h"
to:
#include "wiring.h"
This will make it break on Arduino > 0011, so a better trick would be to upgrade your Arduino IDE.

Hi,
I've added this as an issue for Sanguino, so it should make it into the next release.

I'm using a customized firmware which I wrote to fix some issues in the first version of the GCode firmware. Unfortunately, the different GCode firmwares have diverged a bit since then. I've been hoping to go through and merge them again, but the longer I wait, the more work it is : /
I'm using this together with Skeinforge and ReplicatorG btw.

I haven't run this firmware myself, so please shout out if smth. is broken.

Nice
If we create makefile rules to automatically scan for .pde's, regenerate main.cpp, and upload the sketch to the bootloader we have a stand-alone solution.

Hi,
I just fixed this in svn.
Ian, FYI: The problem is that Arduino preprocesses the source code in an unintuitive way. To my knowledge, this causes header files to be included before the main Arduino headers which define things like byte and word. Otoh, .pde files are included in the end, causing the Arduino keywords to be defined when there are compiled.
In effect, also to my knowledge, all .

I added a small comment on Java 5 vs. Java 6 here for clarification:
I tried to play around with the host software on Mac myself back when it required Java 6, but I had to give up as it was too time consuming to get it to work properly.
After that I moved to using Skeinforge and eventually ReplicatorG.
If there are any Java programmers out there using a Mac, it would be awesome to get the host

The bootloaders are compiled using gcc-3 while the default for Arduino is gcc-4.
I'm pretty sure (although not 100%) this is the case also for the built-in Arduino bootloaders.
You can run 'avr-gcc-select 3' to set the default to gcc-3.
It's also possible to compile the bootloader using the -Os flag to optimize for size. This is not tested, so do this on your own risk.

Zach just pushed out the Sanguino-1.4 release
I hope this will work for you.

I added this function recently, so it's definitely not part of 1.3.
If you want to be on the bleeding edge, you can of course use the current sources instead of the 1.3 release by checking them out from svn.

It's in the latest Sanguino sources in svn.

Driving such a motor in bipolar mode would inherently give more torque due to the fact that twice as much coil is energized at a time.
It probably won't do wonders though, but at least you'll learn smth. by doing it, so it's probably worth a try,

As you describe it, it shouldn't have compiled.
My guess is that you inadvertently had the brace after the else missing as well.
That would fit you problem description.
Anyway, if you experience this again, feel free to post it here

Hi Chris,
I found your rewrite intriguing, especially the overload of built-in Arduino functions.
However, I didn't get the latter to work; I've tried it on various versions of the Arduino IDE, although only on Mac OS X, but always get issues with multiple definitions of global variables.
I was wondering if you have any insight into why this is and some experience with known-to-work combinations

Hi Enrique,
There appears to be a critical bug in the latest version of Skeinforge.
With the default configuration, the Z values don't increment between the layers.
The layerStart comments show the correct Z values, but the G-code Z values are always the same.

The original SD card firmware, on which the LadyAda and Zach's firmwares are based, has been updated to support FAT32 and SDHC:
I just tested the new version on a Motherboard:
My dirty hack is here:
Cleanup pending.
