Re: Arduino 12 issues? - 17 years ago

I just updated the Single_Arduino_SNAP libraries in subversion. They _should_ now build on Arduino-0012 and the reported problems of the firmware being too large to fit are also resolved. I don't have a setup which works with SNAP, so if anyone cares to give this a spin it would be great.

Hi, I assume you mean _DXF_. In that case, I've been using pstoedit (http://www.pstoedit.net/) and it works like a charm.

Re: How to print Gcode from Host - 17 years ago

Enrique, Playing around a bit with oozebane, I think I have a suggestion for improvement: Today, when the extruder is turned off for a very short time, e.g. when moving up to the next layer, the oozebane kicks in. The value of oozebane here is minimal, and only useful if the parameters are tuned perfectly. My suggestion would be to implement a minimum time the extruder has to be off before ooze

Re: Arduino and Mac OS X setting - 17 years ago

This is a debug build with extra debug messages. To disable them, either get the latest version of rxtx, or compile it from source. You might have to patch it according to my suggestion on the mailing list. I haven't followed this project for a while, so I don't know if this has been fixed by now.

Re: How to print Gcode from Host - 17 years ago

Hi again, We've been playing around a bit with towering and combing and have found some dubious behavior with these settings: Look at the attached file. It describes two circular towers with single-filament-width walls. We observe the following behavior which we don't quite understand: 1) When only combing is used, the extruder makes two entire round around each layer, both on the inside and t

Re: How to print Gcode from Host - 17 years ago

The Arduino GCode interpreter does indeed support the M108 command. I've always been using the latest version from Subversion, so it might be that you've encountered a bug in the current released version. Zach has mentioned that he'll try to get out a new release soon. In the meanwhile, you could try the bleeding edge

Re: Arduino and Mac OS X setting - 17 years ago

Yeah, that's my debugging messages identifying another crash. Unfortunately, I didn't get around to start debugging that one..

Re: Arduino and Mac OS X setting - 17 years ago

Hm, this is really a bit out of my league... Tips for debugging: o Test with Java5 vs. Java6 o Test on other OS'es o Test with a different vendor of usb2serial adapters o Test in 32- vs 64-bits JVMs The issue I'm talking about is _only_ related to 64-bit JVMs so you need to make sure this is the only place where you're experiencing this problem. Otherwise, you'll be barking up the wrong tree.

Re: Arduino and Mac OS X setting - 17 years ago

Hi again, I've attached the libraries I compiled which includes a fix for some of the issues. I haven't used this myself for a long while, so I cannot guarantee that it will work though. At the moment, I'd recommend porting your software away from Java 6. Alternatively, you could work with the guys on the rxtx mailing list to help getting these issues sorted out. AFAIU, this is not a Mac-specif

Re: How to print Gcode from Host - 17 years ago

I guess you're aware of this, so just FYI: This update didn't appear to resolve the ZeroDivisionError I reported a few days ago. Another thing btw.: Eventually, we would like to spend some time getting dirty with the skeinforge source code to be able to fix stuff and experiment with our own ideas. Do you have any suggested starting points for this? Also, whenever we get this far, it would make

Re: How to print Gcode from Host - 17 years ago

Hi Enrique, I'm experiencing some problems with the latest Skeinforge (using the latest revision from svn). Basically, Skeinforge crashes with a ZeroDivisionError. This happens with a lot of models, and the problems started with the latest update. The revision from ca. 3 weeks ago works well. To reproduce, use the default values for all preferences except these: slice_shape: Extrusion Diameter

Re: Native USB instead of usb->serial convertor - 17 years ago

If you're using an atmega8, you have to implement the USB stack in software as this device has no built-in USB support. In addition, the 8KB memory on this one is far too little to fit the Reprap firmware. ..or did you mistype your device name? Regarding USB, using CDC instead of HID would give us the same behavior from the host's point of view. This would simplify things a lot in terms of conn

Re: OSX 10.5 Software startup issues - 17 years ago

Also note that you're pretty much on your own if you use a 64-bit JVM since the 64-bit support on the RxTx library is a bit flaky. Have a look at the rxtx mailing list for more information. I haven't tested this in a while though since we're only using the GCode pipeline atm., so the 64-bit support might have improved lately.

Re: How to print Gcode from Host - 17 years ago

Thanks for the update! I'm attaching a gts file which gives the following message 24 times during the comb stage: "This should never happen, closestBetween should always exist." The models extrudes fine nevertheless, but since I don't have any experience with comb, I thought I'd let you know. I can send you the aoi file if you prefer.

Thanks for the update Enrique, I have a few issues (and also a few fixes - will post once I have the toolchain running again), but I'm stuck on one issue (see below for the trace): It appears that there is a problem in gcodec.getModule(). You're using an absolute filename as an argument to __import__. This is, AFAIU, not according to the documentation and fails on my system (Python 2.5.1 on Mac

Re: Java versions and the host software - 17 years ago

Thanks I've had some headaches with Mac OS X and Java 1.6, due to the fact that Java 1.6 on Mac comes as a 64-bit only JVM, meaning that all JNI libraries also need to be 64-bit. At the moment, rxtx appears to be the only problem, which is partially fixed (although it still crashes some places). It would be nice if we can keep the host software on 1.5, at least until the 64-bit stuff stabilizes

Re: Arduino and Mac OS X setting - 17 years ago

Hi, This is a bug in rxtx. I've written a quick fix for it. It doesn't fix everything, but it makes the host software run. See here for the patch: I didn't update the reprap wiki yet since there is still a bug lurking in there somewhere. Don't hesitate to get in touch if you need more assistance. -Marius
