Re: [Emc-users] Expansion of EMC
Bootstrapping is not the issue. I've already got a business. $20 will start you in some businesses, but don't try and become an industrial contractor with that. The issue is the ability to go after larger jobs, and for that you need capital and equipment. Anyway taking money from the government is immoral... Seriously? If that is the case then most of the nation is immoral. If you accept a tax credit, then you are accepting money from the gov. that demand is now in Asia. If I was still young I would move to where the capital is. No doubt but much of that demand is now not in the US and that is a real issue for those of us still trying to do business here. Asia is a mixed bag. Ever do work in China? I haven't but I have friends who have spent months there and only go there because their jobs require it to do installations. The working conditions are oftentimes very bad. One guy I know got very sick while there and had to be hospitalized there and when he got back. Bad food and water. But things might be changing. I heard the other day that GE is bringing back all of their appliance manufacturing to the US from abroad. It turns out that the cost of shipping and the problems with quality control in 3rd world countries makes manufacturing there must less attractive than they thought. I've heard the same from a couple of my customers who shut down their US production and were buying containers worth of parts from China. The items were dirt cheap but the quality was unpredictable. Sometimes 50% of the parts would be rejects yet their chinese suppliers would refuse to compensate them for the bad parts arguing that they should have been good enough.

Re: [Emc-users] Expansion of EMC
Gentlemen, Heh - way OT - sorry - I just cannot resist Anyway taking money from the government is immoral... Seriously? If that is the case then most of the nation is immoral. If you accept a tax credit, then you are accepting money from the gov. The immoral part of taking money from the government is that the government has money to give away. The government (taxes under threat of violence) (takes under threat of violence) (steals under threat of violence) (synonymity here) money from each one of us and then determines what the government thinks is the best use of it and gives it away to further the goals of the government. THESE are the immoral/corrupt acts. Our government is a fraud. Our banking system is a fraud. Our legal system is a fraud. Feel free to detect a small amount of cynicism and angst in my position. Government is no longer of/by/for the people. Government (a collective term for government,banking,industry,judiciary) is taking from/exploiting the people. This is normal and history has seen this cycle many times. The driving force turning us into a 'third' (and I use this term with respect for the third world nations) is our corruption is being revealed. Now we (the general population) will have access to the corruption because it will be on top of the table rather than under the table as it has been in this system. This will make the 'corruption' fair, give each individual access AND self control it to a proper level. The EMC2 group of individuals is one of the elite groups of the world. A group that will work on a project or projects to better their life is different than so many other sets of people including many manufacturers. When an industry/group only survives or thrives because of government subsidy that industry is not a valid use of money/time/intellect. This includes some of the largest corporations/universities in the world. The sacrifice of time/money/intellect of the EMC2 group sets it apart from most of the rest of the world. I acknowledge EMC2 uses wild/free code released by the government but EMC2 could/would have been done anyway. It may have just taken longer. I personally had determined I needed a free/software machine control and was searching for just this type of project when I found EMC/EMC2. My first attempt with EMC was an abortion. I had determined to write my own (with help from people I paid) and release it. I looked at EMC again and found EMC2. This group beat me to the punch. The more I am involved with the EMC2 group the more I respect each and every player. We (I include myself in this) are the type of foundation that will be there to rebuild this country after TSHTF. What an amazing group to align yourself with. People that will get up off their butts and go do something to better themselves and others and not depend/wait on the government to come along and provide. I realize there exists an esoteric/selfish side of this group and these types of groups. I also have that attribute. Sadly, we are all human and not all perfect (I am only speaking of myself here) :) . I still believe this type of people is the best to associate with. I am sickened by the developments of our government but I also acknowledge we (this includes everyone in these United States of America) have the government we deserve/want. It will not change until our 'wanter' changes. Our collective 'wanter' is about to change and it will be dramatic. The type of people in the EMC2 group will welcome the change. MUCH of the rest will hate it. There will not be a 'government' program to provide the basics when times are tough.

Or go the other way and make it fully network attached with all the touch screens, web cams, and other gizmoz anyone wants to attach. Then it is a 'product' and you aren't selling EMC2, or just the service of providing configured EMC2. ... I wonder if this would 'sell better' than a software only product? Yes, I'm certain of this. Look at Centroid/Ajax, they have very much a similar business model. They have a box which has CPU, power supplies and servo drives. You pick motors and other minor accessories from a catalog, add to the basic control box and send them payment. A big box comes, you unpack and attach to the machine, plug cables into connectors and turn it on, set a few things like travel limits, and it is ready to accept G-code. I seriously doubt anybody could make a real business selling EMC2 just as is. Somebody definitely COULD make a business doing EMC2-based retrofits. They would settle on interface cards, motors and drives, and have a range of these to suit the size of the machine.

I noticed an extra diode on my Bandit drivers opto's. My guess is that the opto diode has a lower reverse break-down voltage and the additional diode shores it up? I'm concerned about the buffer output, which could have a pull-up, pull-down, and or current limit resistor. I suppose a Zener on the output could help with over-voltage or reverse voltage, but the buffer is supposed to be driving an input not a source, but an inductive load could be a source, but... I usually put off the output components until I know what I'm going to hook it up to. Though, this doesn't help in coming up with a more generic consumer grade product.

Re: [Emc-users] Expansion of EMC
I heard the other day that GE is bringing back all of their appliance manufacturing to the US from abroad. GE, we learned just last week, is now basically owned by our government - I would suppose that is why they are making such an illogical move. ( Further, I expect the political class to continue to make movements towards protectionism as our economy continues to unfold - which will trigger trade wars, where we lose even more manufacturing. ) Yes, China quality is not consistent - just as Japanese quality wasn't in the early '60s. Korean quality is fine, as is Taiwan and other places. If there are places where people can work hard and keep the wealth they create, they will find a way to make quality products. My main point, as someone that sells control equipment, is Don't create a product in search of a market. (that also happens to be one reason why socialism always fails in the long run ). To use EMC to create wealth, one bumps into the economic mess we are in. To succeed, you have to accept the current business reality, and it doesn’t' go away just because you quit looking at it. A lot of the people are feeling the pinch. Transferring wealth by spending huge amounts of stimulus money won't fix the problem - it only buys votes and creates a new bubble, that when it bursts, will make the last crash look like a walk in the park. Transferring the debt of companies too big to fail to the government, only means we will learn that the US is not to big to fail. ( This is not a political thing - the bailing out happened with the support of both parties ). Control equipment sales in the USA are dead - no sane person would risk their OWN money putting in a factory with the anti small business policies in place. In the mean time, the capital really has moved to Asia - this is not a political point of view. ( I blame both parties for letting it happen). The guys with the cash get to call the shots. More than half of my sales are now overseas. This is the new business reality - ignore it at your own risk. In 1900 the UK was the greatest center of capital in the world. People that moved to the US with the capital did well. The UK ended up bankrupt - bailed out by the IMF in the '70s. Sadly, I don't think the political progression is stoppable. The center of capital has once again shifted and if I was young and wanted to do machine manufacturing, I would be looking for a way to someplace in Asia (I would go for someplace outside of China).

The servos are pretty close to an amp per ft-lb. with a 2:1 belt drive - that gives us 80ft-lb peak at the screws. That is pretty close to what the old hydraulic servos. I wouldn't call 16000 Lbs linear force limiting. It sounds QUITE sufficient for such a machine. You don't expect a machine like that to be doing high speed contouring, but I suspect it can probably do anything that the available spindle speed makes practical.

Being a tree hugger, I'm all for making sure a product is fit and safe for the environment, neighbors, customers, etcetera, but it sure is easier to do this in-house. There is some grey area, as machine tools are nominally for factory use, which is in a different EMI class from home or office. Parts, boards, sub-assemblies are not required to be tested in the US, unless they fit in standard enclosures like desktop PCs. Otherwise, the rule is any complete unit that is powered from the mains and uses digital circuitry with a clock rate over 9 KHz must be tested. There are some exceptions for ultra-low power devices like digital wrist watches and similar devices which by design probably have real low radiation potential. Testing of boards and similar subassemblies intended to go into another housing is pointless, as the housing will make a HUGE difference. But, they do require testing of any board that plugs into a PC and has an external connector, as that connector can release interfering signals. So, the way I interpret the rules, all the boards I make are exempt from testing. But, if I made anything that had a complete housing, so a user would just plug in motors and connect to a computer, that WOULD require testing. I did this for a standard product I made 20 years ago that hooked an editing VCR to a PC, and it cost me $3K, I think. The rules have gotten more complex, so I understand such a test would be $10K now, for the industrial-level of test. If you want to do the home-level of test, it is more complicated and more expensive. In Europe, you can do these tests in-house, in the US it is forbidden. You can do your own pre qualification tests to try to be sure your product will pass first time, but you are required to have a testing lab that is registered with the FCC (or international test house that can perform the tests to the current FCC rules) do the test and write the test documents.

I've noticed Matt's circuit is leaner because it doesn't need one. My circuit might be improved with some I/O protection, but that will make it more complex. For just one 74HC14, a resistor and 5.1v zener diode will do. I'm used to a Zener on a gate input to limit the input voltage, but the circuit input is an opto-isolator which is not so delicate. Sorry for confusing by placing the zener comment one sentence too late. It was intended to suggest using the zener in place of a voltage regulator IC. If there's little else requiring +5v, then a resistor and 400 mW zener will do to supply tens of milliamps at 5.1v. (Perhaps 5.2v when the load is low, and the zener has to shunt more.) I noticed an extra diode on my Bandit drivers opto's. My guess is that the opto diode has a lower reverse break-down voltage and the additional diode shores it up? The reverse breakdown voltage of a LED is not high, so the normal input voltage applied across LED and series resistor can easily be enough to destroy the LED, if accidentally reversed. (I avoid putting even 5v reverse polarity on them) The series diode blocks that. (My habit is to connect any old diode backwards across the LED, to clamp reverse bias at 0.7 or so. Any reversed drive is then dropped across the series resistor.) I'm concerned about the buffer output, which could have a pull-up, pull-down, and or current limit resistor. I suppose a Zener on the output could help with over-voltage or reverse voltage, but the buffer is supposed to be driving an input not a source, but an inductive load could be a source, but... I usually put off the output components until I know what I'm going to hook it up to. Though, this doesn't help in coming up with a more generic consumer grade product. That's tricky. You never know what people will do with an exposed output. Perhaps a small relay, with flywheel diode across the coil, even if a transistor is used to drive it, would both provide a robust output, and be easy to include in an Estop chain?

David Winter wrote: Hello All, I would like to ask a question related to the commecialisation of EMC. I work as a Service Engineer fixing CNC machinery. One of our customers has a machine with an Acramatic A2100 control, this control has some serious problem with it. So, the question is, if I was to retrofit this machine, how would the board and all of the contributors feel about my using EMC as a control? I have some reservations about this as I don't feel it's right to profit from people's efforts which they have contributed for free. Comments anyone? What do you THINK EMC2 was created for? For 6 guys to run a machine in their garage? I am as sure as any of the non-core developers can be that they WANT EMC2 to be used, and retrofit/updates are great candidates for it.

Re: [Emc-users] Expansion of EMC
If I remember right, EMC was initially developed by the US Department of Commerce's National Institute of Standards and Technology (NIST.gov) to help spur automation in commerce and industry (or some such). So yes, it was made for 6 guys to run a machine in their garage, AND for anyone (companies included) to enhance and expand products to grow the economy. Since it was initially developed, it has had lots of continuing development, and been put under current licensing. Initially is was own by the US Gov, and was distributed free for use (as being in the public domain, ... different than the current license). -- Oracle to DB2 Conversion Guide: Learn learn about native support for PL/SQL, new data types, scalar functions, improved concurrency, built-in packages, OCI, SQL*Plus, data movement tools, best practices and more. http://p.sf.net/sfu/oracle-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
