Hi, I'm having a hard to installing the new EMC live cd... i am installing on a clean HDD with no other OS on it. 1st I've booted up from the cd and then installed it. once it reboots the load screen just hangs. i have downloaded the iso a few times and from both servers just to make sure i didn't get a dodge copy. that did work so i downloaded the latest ubunto to install.. that works fine but now I am tring to insall EMC from the cd and there is more trouble I've downloaded the .sh install file from the linuxcnc site. the terminal opens up. some lines come up and then it closes.. from the linuxcnc site they said the install should come up after this but i get nothing.. i hope this all makes sence? can any one asist me?

Re: [Emc-users] (no subject)
The idea of respins is that you can create multiple different versions easily. So you could have a minimal version and a minimal with network version for example. Plus as long as you have network support in the respin, it is always possible to use the repositories to install more software - just like the LiveCD Ubuntu provides.

Re: [Emc-users] (no subject)
I find this fascinating. Long years ago after some preliminary work by Will at NIST, I authored a knoppix-emc CD and worked with Paul while developing the Morphix (take the red pill) version that became the debian BDI. A couple of things come to mind. One of the concerns for me, being at the far end of many miles of very old copper is that updating and maintaining a large install like the ordinary Ubuntu is a time and resource consuming thing. At best I get about 3k dribbling into the basement. Yes times change. Long years ago that was FAST. But then long years ago I used to ask for large core on the IBM and that was a plain ordinary 512. We are a mixed bag of users here. Our motion control industrial roots suggest that we buy/build machine tools with dedicated controls. Our PC backgrounds expose us to all kinds of new ideas. Hell point-and-click was new not that long ago. I remember seeing it for the first time on a PC running unix and a predecessor of X11. That was a couple years before MS 3. So times and technology changes the nature of things. I think our current raft of developers/leaders were wise to choose Ubuntu. I didn't think so at the time but old dogs can occasionally find new fire hydrants. Ubuntu has most everything to satisify folk that are in process of migrating from the PC crowd. It certainly fits with the release often line of thought and provides a nice web path to keeping current -- if keeping current is your thing. At the way other end of the user spectrum, a stand alone machine tool control, I've built a few near embedded systems that start up in an EMC window with the last program reloaded and stop when you turn the power off. Now to the heart of my initial thoughts regarding reconstructor. Cleaning out unnecessary stuff after an install can be really time consuming. Building a bootable CD can be really time consuming. A good CD building helper will reduce the size of the step required to get into the business of building these disk images. If it works it can allow us to offer several levels of install along the embedded - full blown continuum. And at this point I need to thank all for their contributions. We have an awesome OS project.

Mick, Have you tried running the EMC2 cd as a Live cd - that is, don't install it, just put the CD in the drive - it should start up and give you the Ubuntu screen from which you should be able to run EMC2 from the file menu. It will run much slower than normal but if it runs from here, it should run from an install. One thing you could check is whether your screen resolution etc. is set right - video cards can give all sorts of wierd problems. Also, are you accepting the default repartitioning of your hard drive? -- Best wishes, Ian Ian W.

Re: [Emc-users] diesel motor control
Hi all, In 1975 I installed a mil surplus diesel in a 3/4 T pickup. Ended up putting about 5000 hrs on that rig. Never did anything heavier than 27,000 GVW ... (with 55 hp at the flywheel) ... big grunt. Injection pumps, especially the inline ones are very reliable. If I were to fool with that kind of thing today I'd work on dynamic timing; i.e servo the rotation of the pump to get the optimum timing curve vs both rpm and load. Less smoke and a bit more efficiency. I suppose you could actually rotate the shaft of the pump with a servo but I was thinking about just moving the pump a few degrees (maybe 30) to adjust timing. Having said that injection pumps are noisy. Just listen to one on the test stand when it is being calibrated. Most of the click-click at idle is the pump. Maybe the electro- mechanical would be quieter but I wouldn't bet on it. You still need enough pressure to atomize the fuel.

I thought progressive valve and injection timing was pretty neat. That was not done with the EMC of the day, but could have been.

Re: [Emc-users] diesel motor control
You got my attention with this! I'm a diesel likin' man myself - I have a Mercedes diesel car and an older Ford diesel pickup and a couple of diesel tractors. I've often thought of doing something like you're talking about. I'm currently using and programming PIC microcontrollers at work, and I'd agree with Javid that a microcontroller might be a better fit for the job. Seems like the hardware requirements with EMC would be kind of an overkill? Anyhow, I'd like to hear more about your project as it comes along. It might inspire me to actually do a conversion like that on a diesel motor or two I have laying around. Moses Stuart Stevenson wrote: Gentlemen, This doesn't have anything to do with machine tools.

Re: [Emc-users] diesel motor control
Stuart- You are probably better off doing it in a microcontroller than EMC. A friend and I converted a car to run on Ethanol back in the early 90's (yes, way ahead of our time) and fooling around with the injector timing was the tricky part. That was a throttle body fuel injection system with a single injector-a relatively simple task. How familiar are you with microcontrollers?
