Re: [Emc-users] LinuxCNC: The new name of the EnhancedMachine Controller
The only downside is the confusion factor, there are thousands of people who have heard of our EMC2 as another CNC control program, and now will not know what happened to it. For instance, there is an EMC forum on CNCZone. I suppose that needs to be renamed, too. Since we're not responsible in any way for that forum, we can't enforce the change. It's up to the CNCZone forum admins to request/make the change if they think it's appropriate. Regards, Alex -- Keep Your Developer Skills Current with LearnDevNow!

Re: [Emc-users] LinuxCNC: The new name of the Enhanced MachineController
I join this opinion based on the facts that this (EMC2) project has a long history under its current name. It's ridiculous to see a not exceptionally successful company (http://finviz.com/quote.ashx?t=EMC) terrorize nonprofit organization especially when the product has absolutely nothing to do with their core business. No comment ;) My feeling is that their lawyers have nothing else to do, like protect employees of their spinoff VMware etc. Quick search for EMC2 on Google brings LinuxCNC.org in the third place. That's due to the fact that EMC Corp is advertising on the top. remember than in these days everyone who uses google searches can see different things shown. For me, searching for emc2, brings up our webpage in first place. But that's mainly because google knows I frequently searched and went to that page... Google also delivers other links that one would expect to be more offensive to EMC Corp lawyers than LinuxCNC open source product. http://www.emc2.com/ http://www.emc2fusion.org/ http://emc-squared.net/ http://www.aimprogram.com/ http://www.emc-sq.com http://www.emc2architects.com/ http://www.emctwo.com/ http://www.emcsquared.com/ http://www.emc2acne.com/ http://www.emc2interiors.com/ http://emc2payouts.com/ http://www.facebook.com/pages/EMC2/174903925885899?v=info indeed, and wether EMC will pursue the change of those pages is not our concearn (they probably will eventually..) Other (Google) Searches related to emc2: emc2 cnc software linux emc2 e=mc2 emc2 wiki emc2 engineering emc2 fusion emc2 architects emc2 bikes so EMC2 CNC software comes up twice in this section alone. Fact: search for emc2 returns more links related to LinuxCNC EMC2 on the first 3 pages than EMC company. I respect LinuxCNC board decision but wonder about EMC legal department. My guess is that generic search for their products turns up little or nothing and they want more free advertising. http://www.emc.com/about/investor-relations/faqs.htm Q: What does EMC stand for? A: The founders of EMC are Richard Egan and Roger Marino, the E and M behind the naming of EMC. EMC Corporation is the Company's full name. So they were sitting on the fact, and did nothing, all these years that a nonprofit org openly used EMC2 (Enhanced Machine Controller 2) for the project name. There is statue of limitation somewhere, even in the US law one would think. Perhaps they need some http://www.emcpic.info Based on the name shared by multiple entities nothing can be done, if however one of the entities has a trademark on the name, things change pretty much (under US and under international law). Imagine how many links are going to be broken if LinuxCNC wiki page changes every instance of EMC2? That's censorship IMO and I'm against it. I agree with the subsequent answer by Karl: I think it important that the names of web pages stay the same even if the names include emc, or at least put in redirects from the old page names. Otherwise links in past emails will break. Even if links in the email archives are changed, it won't change people's local email stores.

I doubt EMC Corp would have issue with that, since it is for 'educational and historical' purposes. IANAL It seems unimaginable that even under perverse American law, one corporation can own all rights to every use of an abbreviation. In most countries, it is sufficient for the activities of the separate users to be significantly distinguishable for courts to dismiss a litigant's claim to be the only one on the planet with the name Bob. You are right, they probably don't own the rights to every use. Still, in the matter of a lawsuit very seldom the truth is the one that matters. Unfortunately usually the amount of money you throw into the lawsuit tips the scales a bit more than simply beeing right. (better lawyers etc.) If our current full name conflicted, then there would be grounds for discussion, but coincidence of abbreviation (EMC) is no ground for complaint. And both parties have adapted Albert's little equation, so neither can claim originality or exclusivity there. Unfortunately the trademark laws don't completely agree with you ;) That said, the board's decision is the board's to make, and it avoids distractions other than whether or not to make any changes in the wiki. If we place on the home page LinuxCNC was historically known as EMC2, then the job's done, innit? /IANAL I just want to point out that our decision wasn't reached without some considerable amount of thought and negotiation.

I'll attach a board and a schematic file which demonstrate that the anode and vcc pins are in fact on opposite sides of the package. If you copy the files into a separate new project, open the schematic, and say yes to opening the board, the latter reveals the physical relationship of these pins. I've placed one device on the underside of the PCB, so we see a bottom view of the pins for that device.

Andy, I think you can do it easily with a single relay and a momentary pushbutton. Such that to start, you push the button in to bypass a relay contact which supplies AC to the PC. The relay is held in by the 12 volts out of the PC power supply.When the PC shuts down it drops the 12 volt to the drives, which will cause the relay to drop out killing all AC to the PC power supply. Simple, but I think it will work. Dave -- Keep Your Developer Skills Current with LearnDevNow! The most comprehensive online learning library for Microsoft developers is just $99.99!

Re: [Emc-users] eagle-6.1.0 (again)
I really enjoy Gene's war stories!! I, too am a (relatively) old codger, but still young at heart. At the risk of being too far off topic, I'd like to add one more war story to Gene's list. Back in the early 60's, I had a 2-way radio repair and maintenance business. Remember, you youngsters, back then almost everything was vacuum tube based. An oil company I supported had a problem with their dispatch transceiver - after it got warm (it was on 24/7), the receiver's output became so garbled, they couldn't understand what was being said. They could transmit OK, which made the audio final stages less suspect since, in this design, they were shared between transmitter and receiver. Within a minute or two after opening the case, the problem would clear up because the internal heat would dissipate. Using an audio probe, I searched everywhere for the problem, but couldn't narrow it down in the time it took for the problem to miraculously go away! I worked on that thing for a week, replacing filter caps, coupling caps, tubes, etc. trying to fix the darn thing. Nothing!! Then, in desperation, I plugged in an external speaker to be able to listen to it while I jury-rigged a heat enclosure to keep everything hot while I ran down the problem. Viola!! CLEAR AS A BELL!!! It was a faulty speaker! Out of curiosity, I tore the speaker apart and it turned out that the voice coil would warp when it got warm and rub against the side of the magnet, causing the distortion. You could see the rub marks on the magnet where the voice coil rubbed. The end of the story is that the customer got charged for a new speaker and the labor to replace it, while I ate the difference in actual time spent! Part of doing business - and customers wonder why labor charges are so high! I learned a valuable lesson - and that was to always start with the obvious and easiest to check before heading to the more subtle causes!! IN 1964, I took my first job in computer programming and stuck to it for the rest of my 36 year career - and that lesson served me just as well there (if not more so) as it did in electronics. Keep on with the war stories, Gene - they bring back long-forgotten memories!! Dennis -- Keep Your Developer Skills Current with LearnDevNow!

Sourceforge has a process for renaming projects that apply to circumstances like ours. When this is done, we expect most information presently on sourceforge to appear but at new URLs that reflect our project's new official name. The mailing lists will have also have new names (linuxcnc-users and linuxcnc-developers) but retain the existing subscriber lists. However, access to the sourceforge pages and services may be disrupted for a time. If you use a whitelist-based spam filtering system, you will want to preemptively add these addresses to your whitelist or address book. At this point we anticipate filing the rename request around January 26. We'll send another message shortly before filing the rename request with sourceforge, and another after it's completed.

We're well known enough to make a big outfit like EMC have their lawyers call us! That's got to count for something :) Oh, great! Next it will be Haas or Hurco suing us for the use of CNC.

Re: [Emc-users] Changing the scale factor of an axis
I think as long as you're modeling your extruder as an axis, you can't change it's speed without also changing the speed of all the other axes (by using the feed override knob on the motion controller). Also, as long as your extruder's position is controlled by the motion controller, you won't be able to change its scale factor without causing a following error. You might be able to short-circuit the motion controller's notion of the A axis by netting the motor-pos-cmd back in to motor-pos-fb, then eavesdrop on what the G-code says the extruder should be doing by connecting the motor-pos-cmd net to some more hal circuitry. For example, you could run it into a ddt component (to get the g-code's commanded extruder speed), run that into a scale component, and finally run the output of scale to your extruder's stepgen's velocity command input. Then by tweaking the scale.gain pin you would tweak the actual extrusion rate. It might work!

That's because the absolute position of A just moved by a lot. Let's say you've extruded for 1000 A units. The motor is at 1000*200. When you change the scale it suddenly wants to be at 1000*210. If you didn't get the following error you would have instead gotten 1 stepper units of extrusion instantly to catch up. Can I work around this?

[Emc-users] VFD + Induction motor closed position loop
Hello to everybody on this list. I've been working for almost two years with LinuxCNC software (the old EMC hehe) and steppers driving an old Schaudt cam/lobe grinding machine. Now it's time to improve the system and change the steppers for something with more speed, specially for the Z axis. Anyway, the idea is to keep the costs as low as possible. That's the main reason to not to use servo motors. A year ago more or less, Andy Pugh showed that it's not a crazy idea to use a conventional three phase induction motor and a VFD in closed loop with LinuxCNC software for positioning. Anyway, Andy told that his VFD was old, and it couldn't respond well below 200 rpm. Nevertheless, the experiment that Andy did, was really good and impressive. Here is a video of that http://www.youtube.com/watch?v=3oTJNEVpvYY. My question is, what do you guys think, about using an induction motor, reduced with worm and gear and driven by a vectorial VFD, (also there are newer ones that apparently can keep full torque at zero speed), to drive a joint and control position with minimum increments of about 100 pulses of encoder (I'm planning to use an encoder of about 1000 pulses per turn). So this would be 1/10 of a motor turn. Do you think this is achievable taking all of this in consideration?. I mean, the reduction with worm and gear reduces the inertia factor almost to nothing, so the deceleration of the motor would be practically instantaneous. And also the motor would need to turn mostly at high speeds because of the worm, even better if a use full torque at zero speed VFD. I hope you can help me with this, since the idea is not to risk too much spending money on solutions that can't work at all. I'll ve very thanked if you could guide me with this replacement.

I know it's tongue-in-cheek, but since several people have mentioned this I thought I'd reply. EMC corp has a trademark in a very related field.

Re: [Emc-users] LinuxCNC: The new name of the Enhanced Machine Controller
FWIW, Mach3 is relatively safe from attack. Trademarks apply to a particular domain only, and razor blades and software are quite different domain. In addition, there must be reasonable reason to believe that the consumer would be confused by the use of the term, and it is highly unlikely that anyone believes that Mach3 CNC controller is a product of Gillette. EMC was at risk because both organizations provide software, and there is a reasonable reason to expect the consumer to be confused. Honestly, I am surprised it took EMC this long to take action. LinucCNC is a good name. It has been the projects domain for ages. It is much more descriptive of what the software actually does than EMC (granted, Enhanced Machine Controller was descriptive, but how many people used the full name? How many users could not have even told you what EMC stood for?). It seems to me that, regardless of the motivation, the name change is actually a positive change for the community. There are plenty of real bad things to worry about in the world, and on the grand scale of injustices, this one is pretty trivial. My two cents, lets run with the new name and all the free publicity that will come along with the changeover and work on making LinuxCNC a better program.

i have tryed this also u can get close u will not get Servo performance/position resolutions but u can get close.. hence why they say servo like on VFDs spec sheets and it does make a big diff what level of VFD you use also some are alot better at this than others.. Yaskawa do some very clearver VFDs with Vector/servo like performance control techniques or Emerson in US also do very good drives there Unidrive model i think it is depends how big a VFD you need and if you already have motors etc i guess.. as when looking at more fancy spec VFDs price does come into play and servo setup can be had for same sort of price some times.. rob On 19/01/2012 00:40, Leonardo Marsaglia wrote: Hello to everybody on this list.

Re: [Emc-users] VFD + Induction motor closed position loop
Thanks Robert for your answer. I'll be chechink the Yaskawa models and see if I can find a good dealer around here to request quotation. So you tell that you tried this combination with EMC?. And how did it work? It was good for positioning?. I don't need fast interpolations, only individual positioning movements to place the grinding wheel and the part.

It is not a copyright, it is a trademark. You cannot copyright an acronym, but you can trademark one. A copyright protects a work, such as a novel, a song or a piece of computer software from illegal duplication. A trademark is a brand name, logo, or other distinguishing mark that consumers recognize as part of your branding, and allows companies to protect their name and reputation in the marketplace. Trademarks can be very broad. For example, you can even tradmark a color. For example, no soft drink can use the same shade of green that Mountain Dew uses for their bottles, and in the tool industry, the respective shades of Red, Yellow and Blue used by Lincoln, ESAB, and Miller are all trademarked. Everlast Welders recently had to change from yellow to green to avoid a lawsuit by ESAB. -- Keep Your Developer Skills Current with LearnDevNow!

A boots-first approach works well here, since the schematic and layout contain no magic smoke. If you just whack all your components into the schematic, _and_wire_them_up_, then little yellow air wires will appear between the package pins on the board.

In the future, if there's so much on the board that picking the right wire is problematic, then try using the i Info tool in the schematic. Click it on the desired wire. (The right hand wire in yesterday's demo schematic shows as N$1) Click the Board icon on the horizontal toolbar, and you flick to the board layout.

Re: [Emc-users] Changing the scale factor of an axis
On 01/18/2012 12:41 PM, Lars Andersson wrote: This immediately gives a joint 3 following error even for a very small change. Can I work around this? The problem appears to be, as someone pointed out, that changing the scale factor also causes a step in the output due to a multiplying the (possibly large) position by a different scale. One answer would be to create a real-time hal component, into which you would feed the position and the desired scale factor. I'd have to think about this to be sure but this is probably close: when the scale factor changes, the component would (from then on) subtract from the output the value of -current_output * (new_scale_factor - old_scale_factor) so there is never a step in the output when changing scale.

Re: [Emc-users] LinuxCNC: The new name of the Enhanced Machine Controller
Interestingly, if you google emc opensource, buried among all the excellent enhanced machine controller articles, there is reference to the other emc and their foray into open source. Maybe this is how they get their google search rating up. -Original Message- From: Stephen Wille Padnos [mailto:spad...@sover.net] Sent: Thursday, 19 January 2012 11:57 AM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] LinuxCNC: The new name of the Enhanced Machine Controller I know it's tongue-in-cheek, but since several people have mentioned this I thought I'd reply. EMC corp has a trademark in a very related field. I don't recall the specific area, but it had to do with computer hardware and a particular area of computer software (backup most likely). Though we as a group understand the differences, it may seem related or the same to a non-expert observer. It should be obvious to anyone that PC software and razors are entirely unrelated.
