Re: [Emc-users] (no subject)
My 6.06 install runs nicely on a PIII 660MHz but I had to add memory upping it to 384mb for reasonable latency results. I've also had it running on a Pentium (the first class...) but never actually ran it, just tested the interface and got familiar with it. Are you getting an error message on the crash or just lockup? Onboard or separate video card? If you have a junk box try swapping some different hardware into the setup. You are installing it from the LiveCD ISO from the emc linux homepage not from a combination of Ubuntu and then compiling emc right?

Re: [Emc-users] Arduino with Ubuntu 8.04
Alex Joni has uploaded a new version of the kernel package which includes the ftdi_sio driver. If you can, please try the new kernel package by downloading http://www.linuxcnc.org/hardy/dists/hardy/base/binary-i386/linux-image-2.6.24-16-rtai_2.6.24-16.30.linuxcnc.4_i386.deb and installing it with dpkg. If this works for you (both ftdi_sio and emc2), then we'll probably make the package available through the regular update process. Thanks again for reporting this problem, and I hope the new kernel package fixes this for you without the problems you mentioned relating to having your own self-built kernel package. Let us know the results.

Thanks Jeff, I get the cue. I just tried with tool = 0.5 and it worked perfect. I did not understand why it was able to do it in inverted, but with your explanation its obvious!

Re: [Emc-users] image-to-gcode BUG: Incorrect depth in gcode
I think that image-to-gcode may be working as designed, though I understand that it's not giving the results you want. Your screenshot shows that you specified a tool diameter of 2mm and a pixel size of 0.5mm. That means that the tool covers 4 pixels. But in your antialiased images, the blackest parts are much less than 4 pixels wide, so image-to-gcode tries to figure out exactly how far in the tool can go without cutting away any of the material you wanted to remain. (and because of antialiasing and jpeg compression, few of the pixels are actually totally black) There's not currently a way to tell image-to-gcode that you'd rather err on the side of milling away more material. I got results that may be closer to what you want by: * opening the image in gimp, choosing (layers>)colors>threshhold, and setting the low value to about 190. * then set the tool size to the same as the pixel size in image-to-gcode Jeff - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] SMI-Like latency problems that don't respond to rtapi_smi.ko fix
This might not be of any help to you but my home machine - an IBM E Series X Server 205 is unusable for EMC because of the RTAI delay problems. I only run in Sim mode at home (duh!) but put up with and ignore the errors just to see how a job will run. Running the latency test on this machine shows well over 1,000,000 (count the zeros). I think I've checked all the usual bios things to no avail. I will re-check all those settings and post back the results. This machine runs great for all other software and I've never noticed any glitches in day to day things I do. Some motherboards just don't seem to be suited for rtai. -- Emory On Sat, Sep 27, 2008 at 20:06, Peter Boyer <[EMAIL PROTECTED]> wrote: > Hi all, > > This is a first time posting so excuse my newbie-like characteristics.

(I have not attempted to turn it off yet.) I don't know if this will help, but go into the BIOS setup and make sure that "USB Legacy Support" is turned off. If that's not the actual wording in the USB options, then post what they have and I'll try to advise you. The other thing to look at in the BIOS is "Power Management", if possible, disable it completely. > I'm pretty frustrated and don't really know where to turn. Any ideas? There are some motherboards that just aren't going to work. It's sad but true. One final possibility is to upgrade the BIOS to the latest revision. If you can identify the motherboard make and model, this is not too hard to do as most makers have BIOS updates available to download.
