It started out designed to be able to run a variety of hdw+sftw platforms. It was only as time has passed by that a particular hardware/software came to dominate EMC installations: the X86 PC + Linux combination. Well, some time around 1995 it ran on Sun workstations. Before that part of it ran on a VME backplane; I don't remember what the processor was. :-( Dave (I know some will remember that EMC ran on Windows in the early days and that this was not considered a bad thing.) No, I don't think this ever happened. Fred Proctor bought an expensive ($2000 per node) real time extension to Windows (I'd guess it was NT) and built something very close to our current latency test. It was HORRIBLE, and as far as I know, the project stopped right there. I think there were latencies of up to one SECOND several times a day. They tested Linux and an early RT-Linux patch and were pleasantly surprised.

I think I may have been vaguely aware of your work on this, but was pretty sure it was never completed. The RT problem, of course, is the big one. But, my comment above was not related to your work, but something that happened well before then. It was mainly porting the GUI ONLY, to Windows, just so people could see what it looked like.

Re: [Emc-developers] Beta release of circular arc blending
Robert, Today I found the time to install 12.04 LTS on my router controller, build the circular arc blending beta branch and get it running. Everything seems to be working wonderfully with a dry run. The program that I tested is a 4.8MB 3d shaping g-code program. On the 2.5 release without arc blending it takes 38 minutes to run. With circular arc blending it takes 27 minutes. To me that is just a HUGE improvement and I cannot say thanks enough for your work so far! I don't know when else I was able to flip a switch and get that much improvement in my manufacturing process! Big big time savings for me. I think these changes will be just as huge for the linuxcnc community overall and will really help linuxcnc's reputation. I am a software developer as well, so whenever you need a buddy build, debugging, help, etc... feel free to ping me. I'll help when I have time. I'll chirp up again after I make some real cuts tomorrow with any issues I see in the parts I make. P.S. The only issue I had was the first time through the build it was complaining about not finding cscope. A simple apt-get install did the truck. I suggest that a check be added to ./configure to alert the user of its necessity prior to building.

I can't thank the folks enough who have helped along the way. The testing and feedback has made it much easier to develop. I am a software developer as well, so whenever you need a buddy build, debugging, help, etc... feel free to ping me. I'll help when I have time. It's a lower priority, but if you're feeling adventurous, I have an 'experimental' branch here that has some newer tweaks and fixes. It hasn't been as thoroughly tested, though it has behaved well for me. https://github.com/robEllenberg/linuxcnc-mirror/tree/circular-blend-arc-experimental My plan is to merge these changes in when they pass all of my test programs on an RT build. I'll chirp up again after I make some real cuts tomorrow with any issues I see in the parts I make. I'm looking forward to it! In particular, see if you notice any machine vibration / surface finish issues, since that's harder to predict from simulation. P.S. The only issue I had was the first time through the build it was complaining about not finding cscope. A simple apt-get install did the truck. I suggest that a check be added to ./configure to alert the user of its necessity prior to building. That's a hack I added to build a code database for searching, but I'll probably remove it before merging.
