I'm not sure exactly what formal classes there will be. I hope we can have something more organized than last year. Ray Henry will be there, so that is likely to be a guarantee! But, even without formal classes, we will have a true EMC "critical mass" there as usual. Just buttonhole one of the developers and ask a question. I'm planning on doing two classes that are oriented a bit toward my products. But, maybe I need to do a general class as well, mostly focusing on the retrofit process and selection of components. If you don't have EMC running yet, bring your computer and we will get it installed and at least partially configured for your own setup.

Yes, a lot of great interaction happens at the Workshop, but (at least for me) a major part of it is to meet with ALL the EMC enthusiasts, not just the "hi test" developers.

Re: [Emc-users] EMC Fest 2008
You get to take your chances. Several of the attendees stayed at the Econo Inn. I stayed there two years ago. They had just changed the beds and the new ones were too firm for me. I will stay at the Holiday Inn Express which is more expensive and farther away; but then my wife will be there also. The Econo Inn is about as close as any motel I'm aware of. Price two years ago was $50/nite. HTH. Dave On May 6, 2008, at 8:48 AM, Dale Ertley wrote: Mr. Stevenson or Mr. Engvall, Can you suggest a motel near to the action.

Hi Dale I'll be bringing a few computers that I want/plan to network together into some sort of 8.04-EMC2 lab. My first class at will start at 8:00 am will be a Linux/EMC2 intro. Monday -- Starting EMC2 in the Ubuntu Linux environment. Tuesday-- EMC2 operator interfaces Wednesday -- Hand coded part programs part 1 Thursday -- Hand coded part programs 2 Friday -- Part programming assistants Beyond this I'll plan to be in/around the lab for a couple hours each day when users can sign up for machines and test ideas and seek help. I'm hoping that several others will also offer classes in the lab during the week.

There is another low-budget motel there that I stayed in a couple years ago. No way would my family stay at such a dive!

Re: [Emc-users] EMC Fest 2008
Hi I want to ask about Wednesday -- Hand coded part programs part 1 Is this programming with G code? I think that use G code to program part possible to find in every community college. Help in G code programming is every way. What is impossible to find it is EMC2 inside. Learn how to make special G code for example 555- G555 with special move is much more important. To learn about G code programming do not need to go to EMC2 fest. Unfortunately the are one place to find about inside architect of EMC2 and it is EMC2 fest. I think that need to establish on line school about EMC2 structure and use ENC2 FEST as a culmination point. I am sure that tuition fee should be applied to on line school!

Re: [Emc-users] EMC Fest 2008
The class I outlined is intended for folk a bit like you were a couple years ago. In fact I drew it back further into newbie than that class. My "ideal" student for these sessions is someone who wants to make parts with EMC rather than someone who wants to make machines that run with EMC. There is certainly a need for work on what I tend to call integration but I wasn't prepared to offer a daily outline of what that might be just yet. Once we open up the machine integration topic we have a range of material from Stepconf for steppers to hand written and edited config file sets that include complex kinematics. Classes would need to include "The Language of HAL," "The Language of PyVCP, the Language of Conf, and Ladder Language." Formal workshop classes are difficult when self-selected folk who cover a wide range of abilities and prior knowledge are included. This workshop environment makes teaching advanced material much more difficult than it is in a formal school setting. When CNC-Workshop spun off from what we were doing at the NAMES show, I thought it was really important to pre-plan projects for folk to get involved with. The Mazak V-5 was my first and Roland was willing to sacrifice it. In that project I found that folk who already knew how, did the most of the work. It was great learning because we needed to prove to ourselves that EMC2 could run production machines and that we were capable of the code and integration work that make these kinds of machines fully functional. (I'm using we in the sense of all of us on the lists, on IRC, ) These days, with the ability to run big multi-axis machines with non-trivial kinematics well established, I think folk come to the EMC2 with ideas about their own projects. The EMC2 is the only production quality software capable of such a wide range of application. Your recent post about a very precise grinder is an example of someone coming to the software with a machine idea. IMO your biggest problem with that machine is mechanical backlash not software or configuration. Such a machine could easily be set up with any current CNC software package. Roland faced a similar mechanical backlash issue a few years back with his skate grinder. Backlash would have killed most machines for the purpose since it had to be accurate to a few tenths over the length of the skate and some arcs were ground with a radius of more than a meter. He came up with what I thought was an innovative solution. What these kind of projects and folk need is very focused self study with a bit of guidance. IMO an apprentice teaching model is much more effective than is structured coursework once you get beyond a very basic level. That Apprentice/master model is what I'm hearing quite a few of our folk offering.

Re: [Emc-users] EMC Fest 2008
Hello Ray. It is right there are people with different interest and level. There are two points that I want to make. 1. there are some help such as G code use that is possible to get everyway any 2 years colleges will offer that. Why need spend valuable time of Fest on it? Help with development of EMC2 is impossible to get, and nobody offers - only one time in year and at EMC Fest. 2. I am sure that need establish on line school about EMC2 to learn about EMC2 year long and not a one week a year.

Most of us are just ignoring him. It may seem rude, but we've tried, and there just isn't much else we can do. Please don't let him get to you, and by all means don't let him dissuade you from teaching your classes. I think Aram's real problem is that he is frustrated. At times he seems as dumb as a stump. Other times he seems to be quite smart, but he just doesn't have the "knack" for integration work. He doesn't read documentation (or he doesn't grasp it), and then he gets frustrated when people can't take his hand and walk him step-by-step through things. Last year he walked around for quite a while with an encoder (or maybe a jogwheel) in his hand, looking for someone to show him how to wire it up. He wound up hooking its 5V supply to 24V and burning it out, and afterwards I swear he still didn't understand why it didn't work. He just doesn't get some things that we consider so fundamental we don't even think about them. I truly think he will never be happy unless someone literally devotes their entire week to helping him (and only him). Maybe he needs to hire someone to do exactly that... but I can assure you it won't be me - I would go insane.

Re: [Emc-users] EMC Fest 2008
Hi Aram, RS-274NGC as far as I can tell just doesn't provide for special functions. It does provide G01, G02, G03. Anything else is programmed by using that facility and programming externally. A few manufacturers have provided splines specially coded within their version of the interpreter ( Okuma comes to mind). More might do so if there were an universally agreed upon standard to representing the splines. To get around this most people with special needs write programs in their favorite language that represent the desired function in G code usually as small straight line segments or as short G02 or G03 segments to interpolate the function to the desired accuracy. This is also true of most of the CAD programs; they output small segments to represent contours, etc. The developers of EMC2 have worked on making the short segment stuff work well and that is within the limits of the present interpreter. So my suggestion is to grab your favorite programming language and go to work. Check Jon Elson's page for an example of hole making. I occasionally write programs to represent contours that are curved in two dimensions. Not too difficult to do. You just have to pay attention to details. A little geometry/trig and a good loop can do wonders.

Ed. > The Mazak is three-phase, and plugs into a twist-lock receptacle, but I don't recall if it is 240V or 480V. Depending on how continuously you will need power we could unplug the Mazak and plug in your machine. I seem to recall that the plug is fed from a disconnect, which is handy for safety. I _think_ there might have been two plugs next to each other, but I'm not sure. I'm certain that there is 480V available - can you scrounge a suitable 480 to 240 transformer? I think you need about 5KVA. As far as single phase 120V for computers and such - there are some limits. Last year when Aram plugged in his coffeemaker it took out the breaker powering our computers. Two years ago Ray hooked up some single phase 480 to 120V transformers for additional 120V. Actually I'm writing this I'm talking to Ray on IRC, and we're planning for more 120V power. There is plenty of 480, and I'm probably gonna pick up a couple surplus 480-120V transformers. Ray will hook them up. (This is single phase stuff - three phase is limited to what is available along the back wall - I think there is both 240 and 480).

I don't know how easy it is to get additional power rigged, but there are a number of twist-lock outlets scattered about. You have to be real careful to get the right voltage before you plug in.

Re: [Emc-users] EMC Fest 2008
A while back someone mentioned video recording the workshop classes and offering them on DVD. Since I will not arrive until Thurs evening at best I will miss most of the classes that have the most interest to me (CL and HAL). On another note, has anyone done much with electronic gearing? I have an old horizontal mill that I would like to convert to a gear hobber, it looks like if you had an encoder on the spindle to track its rotation and a servo on an index head to rotate the work piece it could be done by setting a ratio between them. The problem I see is that the spindle might have to turn several hundreds of times for a complete cutting cycle. Can be done without running out of counters?

About three years ago this topic came up, and I wrote a HAL component that can be used to do electronic gearing. It is done in such a way that it will never overflow no matter how long you run. It will also work for any ratio, as long as the product of the encoder PPR and the gear tooth count is less than 2^31 (4 billion). There is no man page for the component, but there is fairly detailed documentation in the source.

My thought was to synchronize spindle and cutter then feed across with another servo and possibly an axis to drive the knee to set depth of cut. Ed. - Check out the new SourceForge.net Marketplace.

The systems I have done so far have been simple ones that have 4 axiis and a couple on/off SSR's. The outlook is to learn enough to be able to setup a machine such as the Galesburg Mazak, tool changers being the big item. Ed. - Check out the new SourceForge.net Marketplace.

[Emc-users] EMC Fest 2008 Motor Mount Project
Do you guys have the material for the motor mounts? I'm assuming it is 6061 1/2" thick mill finish... Does anyone have the print on this project? If I can be some help with the g codes or fixture plate let me know... John - This SF.net email is sponsored by: Microsoft Defy all challenges.
