I got a letter for petit jury duty a couple of years ago, and was amazed that I was excused because of my age after I filled out the form and returned it. Darnit, I have more spare time than some poor schmuck who has to take a week off from work, losing several hundred dollars in income he probably sorely needs, and I think I can listen to the arguments as well as the next person (if they speak up that is, my hearing had been damaged by my hobbies).

But I don't for a minute believe that is what that particular quote meant when Ed wrote it. Much more along the lines of a rather famous half quote of Thomas Jefferson: "The tree of liberty must be refreshed with the blood of patriots and tyrants from time to time," and the rest of that comma terminated quote is "and God help us if we go 20 years without it." which does not get the well deserved ink the first half seems to get for free.

I'm posting a side view of the tool paths rather than isometric as I think it illustrated the tool paths better. green = .500" SE rougher at 0.1" offset in z red = 0.500" ball end mill at 0.0 offset in z 1770 guns hardly count as an instrument of destruction; more like meat, shoes, and protection. Those were not nice times to live in. This will end up on a short barreled muzzleloader more like the jaeger the german immigrants brought with them but without the european style stock which is/was much less graceful than those of the American made guns. I have thoughts about getting a blog going and if so the instructions for getting the correct contour will be there.

Hi, Finally got brave enough to try something with Synergy solids. The easy stuff was done in 2.5 D but the contour in the pic was done with solids. Used a .500 roughing mill to rough and then a 0.500 ball end to finish plus a bit of cleaning up with a file and emery cloth. ;-) http://imagebin.ca/view/EGO40Lt.html http://imagebin.ca/view/dHfREsy.html Dave -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

I think they are 1 to 1 in degrees. I understand why they built it this way. Simple and cheap, and all the motors are in the base rather than out in the arm. I think the original training mode was point to point.

Re: [Emc-users] Robot Kinematics
Hi Jan, (from the image at http://imagebin.org/33869) When you move the motor for joint q2 Joints q3, q4 and q5 will also move When you move joint q3, joints q4 and q5 will also move. When you move joint q4 joint q5 will move. When you move q5, q4 will also move. Because they are all chain driven (q4 & q5 miter gear) on shafts coaxial with the joints. So for each axis movement, all the following axes need to be moved in the opposite direction to just stay in the same place. The Puma is not like this, as far as I can tell. Each axis on a Puma is mechanically independent of the others. I read the pumakins.h and there are defs for the joint lengths but not for the mechanical interlink that the teachmover style robot suffers from. I need to study the pumakins.c some more. Am I missing something? Dan -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada. The future of the web can't happen without you.

Re: [Emc-users] My campus server don't support the Linux system logging Internet , and I need to revise the kinematics module's inverse tranformation
Yes and no. We provide a simple way to download a source tarball: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Other_ways_of_getting_the_source_code but preparing a system to compile emc2 for the first time is a much more involved process if you can't use apt-get. Everything you need can be downloaded simply over http on port 80 of various webservers. However, we rely on automatic tools (apt-get) that assume an internet connection is available to determine the exact list of packages to download, and the exact download URLs for their newest versions. We do not provide a listing of these packages or download URLs, because it would quickly become out of date. For Ubuntu Hardy, all the required packages are either under http://www.linuxcnc.org/hardy/ or http://packages.ubuntu.com/hardy/ After generating debian/control with debian/configure -r read debian/control.in. For each package name listed in Build-Depends, get the latest version of that package. Install all those packages with dpkg. now, for each package that is required by those packages, dpkg will print an error. Get all those packages and repeat until there are no further errors.

Because VFD's use higher frequency switching, at decent currents, they can create noise on the mains input or other places, but before you spend money, get a second opinion from others on this list, who may have better advise. Another experience I learned from was, with the original motor lead filters on my Hardinge lathe, when I added the VFD, the filters overheated, melted and smoked. Apparently, they tried to do their job of filtering out high frequencies, which VFD's normally put out allot of. The ferrite beads didn't seem have that problem. But I learned this from trial and error rather than informed design, which is not the best way to do things connected with high voltages, currents, mass, dollars, etc. - Kirk http://www.wallacecompany.com/machine_shop/ -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
