[Emc-users] ct f6900 problem
Hi all Got myself a industrial pc, pIII 800MHz, will get 512 MB ram or more. It has VIA chipset. The machine works well under Damnsmallinux (Kernel 2.4.31) and Knoppix 5.01. Whenever I try to get it to boot from emc2 live cd, I do not get further than initram. I also tried to install it on another pc (successfully) and then move the hd to the industrial pc. No cuccess. I passed vga=normal, vga=791 parameters, still no success. Any help available? greets chris __ Do You Yahoo!? Sie sind Spam leid? Yahoo!

Gentle persons: Gene wrote: Another thought comes to mind, gCAD3D-1.40 was recently announced, and I played with it for a bit last night, but it runs in German and the English docs are several years out of date, so that makes for a very steep learning curve for me. Some of the example models it comes with are pretty complex since it can include camera output derived .gif's to aid in the solid model views. Its freeware. And if some enterprising soul were to translate the docs, that would be a huge help. It can output many std formats, although the NC format I looked at wasn't even remotely ours, there may be converters for DXF or DWF or one of the other 7 or 8 outputs it can do. Personally, I'm more attracted to efforts based on openCascade (notably, I'm rooting for HeeksCAD/HeeksCAM) but if you ever run into this problem of foreign-language documents getting in the way of understanding someone else's work, do what real men do and run them through online translators. My two favorites are: 1) babelfish.yahoo.com --- enter the url of interest into the Translate a web page box, select the From/To languages, and hit the Translate button. In this case, I entered http://www.gcad3d.org/doc/IO_de.htm, selected German to English, and immediately got enough information on its IO-capability to decide I wasn't interested in gCAD3D for now. 2) google.com --- enter the url of interest into the Google search engine and select Translate this page for the appropriate search result. Using the same url as above, I got a badly formatted but similarly translated page. I don't like the Google translator quite as much but between the two I've been able to translate difficult technical material, such as Swiss patents, into usable English in a hurry. (In the old days, when I worked shoulder-to-shoulder with scientists and engineers from all over the world, I usually got what I needed by offering beer.) I liked Babelfish better when I was working because I could compose messages in English and translate them passably---but certainly not colloquially---into the language-of-choice of my overseas collaborators (too bad there wasn't a US-AU translator!). As for the NC output format, I don't know what they mean by ISO NC, perhaps ISO 4342:1985 Numerical control of machines -- NC processor input -- Basic part program reference language, a standard which I don't know and which would cost me 280 Swiss Francs to download from ISO and read.

Re: [Emc-users] Mister for small mill
I was looking at misters too once, and it seems the general feeling is it's fine if you're happy to have everything in the workshop coated with oil in a few months. If making a mister, why not just 'mist' oil directly, without the air? Like those 'airless' spray guns. Unless the air blast is a necessary part of the cooling. Just reading another article; - highest smoke point looks to be Avacado oil 520°F/270°C and elswhere; Whale oil was once heavily used in the U.S. for lamp oil and lubricants but not for cooking. The Inuit do use whale oil for cooking as an alternative for Seal Oil http://www.clovegarden.com/ingred/oils.html#seal. Oil from sperm whales (actually a liquid wax) is still the best oil for some precision lubrication applications but is now generally illegal due to the endangered status of whales (the last sperm oil company in the U.S. closed in 1978). Jojoba Oil http://www.clovegarden.com/ingred/oils.html#jojoba is the only satisfactory alternative for whale oil lubricants.

Re: [Emc-users] Mister for small mill
Hi Gene, I've been following the thread you started on a mister for a small mill. I can't advise you on making your own, but I can recommend that you just buy one. The systems I have here in my shop are made by Kool Mist. Hands down they are the best. I never buy mine new, but I find them on Ebay. They come up regularly, and I don't think I've ever paid more than $10 for a single head unit. This is the unit I'm talking about. I think it would be perfect for a small mill: http://www.koolmist.com/images/products/560-18-big.jpg I machine a lot of stainless steel, so I use the #77 Kool Mist coolant. I buy it by the gallon from Enco, and you mix it 4 ounces of coolant to one gallon of water. Here is a link to the coolant: http://www.use-enco.com/CGI/INSRIT?PMAKA=505-2076PMPXNO=947353PARTPG=INLMK3 I have no idea why some of you on this list are having trouble with using misters. I typically adjust mine so the air stream is very gentle, and the mist is barely visible. I use my finger in front of the nozzle to make sure coolant is coming out. Tiny droplets will form on the surface of where you are machining that lets me know the coolant is coming out. They are super easy to adjust. Typically I can machine for about 12 hours on one gallon of mix. Also, my machine shop is a very tight air-space wise because I live in a cold climate, and I don't want to pay a lot for heating (when it's below freezing outside, my gas bill is usually only about $34 a month to keep it at 69 degrees inside. I work in 940 square feet). I never get the fogging some of you talk about, and my machines are always dry and clean. This stuff does not spread itself around the shop and make a mess. Before I started using the misters, my tooling costs where much higher. They are not a replacement for true flood systems, but for an open machine (no splash guards), these little units really work great. I do not work for Kool Mist. I just think you should pick one up and use it. You will not be sorry. David, (a machinist who has been cranking handles now for over 35 years) Gene Heskett wrote: Greetings all; I find that I can get brass tubing in pretty small sizes, like 1/16 OD, usually sized to be a slip fit in the next larger size, so this makes it easy to solder up a small nozzle, with the far end built up to 1/4 for attaching the air supply. Now, I'm wondering if there is a standard formula that would tell me the exact geometry it would take to make a 2 tube, one blowing across the end of the other with air, and the second pulling from a nearby quart of cutting oil, in the same manner as the old hand pumped Hudson sprayers, to add a slight mist of cutting oil to the air blowing on the mill? Angles, center separations etc? I think I can just solder the tubing(s) to another small piece of sheet brass to maintain the alignment. -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Hello again, first off thank to all the suggestions about the encoders I was asking about. I think I'm just gonna go with the requirement of zero'ing position prior to milling any part. My new question has to do with the servo drive's input. When it should be at 0v, the input to the drive sits at about 21mV, which causes the motor to drift slowly, I though this might just mean the balance pot needs to be adjusted, but turning it all the way in either direction has no effect. It should have an effect, hope you are not tweaking the wrong pot... it's been a while since I've dealt with anything on this level, but I was wondering to myself could this be an impedance mismatch issue? maybe I should try a pullup or pulldown resistor? I read in the manual something about the 7i33 already having one or the other, I'll be lookin into that again today, I just wanted to see if anyone had any immediate suggestions or had encountered this before.

I find this all very difficult. I have no latency test under the CNC menu. I looked up the test in Google and found a description for loading it with a sequence of SUDO commands (http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting). But now when I type SUDO on my machine it says it can't resolve the user. So I decided to just reinstall Ubuntu and EMC and it gets to the partitioning and wants to leave the old Ubuntu partition in place. I'm willing to give up the space but the partitioning fails. I tried to use manual partitioning but I don't know what I'm doing and it says no root file system is defined. I don't know what this means.

In a hal file, you use the loadusr command. The user module can be
anywhere
in the $PATH as you say, or you can then specify the complete path to the
component, eg /home/myhome/bin/mycomponent
If you use the wait option on loadusr, eg -W, you need to use the named
version, eg -Wn mycomponent
That's what I do.

Another problem with m5I20 for RC servos is that there is only one rate generator for for the PWM generator so you cant use the PWM generator for other (non 50 Hz) applications at the same time. With HostMot2 you can have PDM for a 7I33 or other analog outputs and setup the PWM for 50 Hz R/C servo support. HostMot2 will still suffer from limited resolution (about 7 bits) because of the small PWM range used, but thats better than the 5 bits m5i20 would give you...

Some of the example models it comes with are pretty complex since it can include camera output derived .gif's to aid in the solid model views. Its freeware. And if some enterprising soul were to translate the docs, that would be a huge help. It can output many std formats, although the NC format I looked at wasn't even remotely ours, there may be converters for DXF or DWF or one of the other 7 or 8 outputs it can do. Personally, I'm more attracted to efforts based on openCascade (notably, I'm rooting for HeeksCAD/HeeksCAM) but if you ever run into this problem of foreign-language documents getting in the way of understanding someone else's work, do what real men do and run them through online translators. My two favorites are: 1) babelfish.yahoo.com --- enter the url of interest into the Translate a web page box, select the From/To languages, and hit the Translate button. In this case, I entered http://www.gcad3d.org/doc/IO_de.htm, selected German to English, and immediately got enough information on its IO-capability to decide I wasn't interested in gCAD3D for now. 2) google.com --- enter the url of interest into the Google search engine and select Translate this page for the appropriate search result. Using the same url as above, I got a badly formatted but similarly translated page. I don't like the Google translator quite as much but between the two I've been able to translate difficult technical material, such as Swiss patents, into usable English in a hurry. (In the old days, when I worked shoulder-to-shoulder with scientists and engineers from all over the world, I usually got what I needed by offering beer.) I liked Babelfish better when I was working because I could compose messages in English and translate them passably---but certainly not colloquially---into the language-of-choice of my overseas collaborators (too bad there wasn't a US-AU translator!). The web/download page does have an English version, its the docs in the install package that are pretty much all in German.

As for the NC output format, I don't know what they mean by ISO NC, perhaps ISO 4342:1985 Numerical control of machines -- NC processor input -- Basic part program reference language, a standard which I don't know and which would cost me 280 Swiss Francs to download from ISO and read.

Most are cheaper than olive by wide margins. And many are even cheaper than ACE Hdwe's cutting oil, as its about $7/qt. Simply pick an oil with a high smoke point and have at it. http://en.wikipedia.org/wiki/Cooking_oil Looks like safflower oil has the highest smoke point, I'll get a quart next time I'm at the gittin place. has a good table of smoke points; some are over 500 F. :-) The point about not using castor oil is a good one. I wonder about forming the small hole in the mister by simply squeezing the brass tubing around a small mandrel like in forged rifle barrels. I found, when I arrived at the hobby store today, that I didn't have any of the smallest tubing, which is 0.062 in diameter, and a very small passage. So I now have a brass block made up as described, and the mill was able to drill a 1/16 hole that is very snug on that tubing, so I made the inner nozzle projection adjustable, and it is quite well centered in a 5/64ths inch air hole. I also found an air filter whose bowl will hold about 2 oz of oil. I will feed the main air through it, which will pressurize the bowl to match the air pressure (less than 75 psi because of the 1/8 vinyl hose for everything). I also put a teeny needle valve in the oil hose attached to the automatic valve in the bottom of the bowl so I should be able turn it down quite a bit. With the bowl mounted on the mill head, and slightly below the nozzle, just turning off the air should stop it all. Not tested yet as I need to fabricate the filter bowl mounting yet. I hope you are not seeing rapeseed being sold for human consumption. Until I read this, I though canola was just rapeseed oil specially processed. By definition rapeseed is high in euric acid ( C22:1) and NOT heart healthy. Canola is the result of seed breeding programs to produce a low euric acid, low glucosinolate rapeseed. Canola is a trademark (Canada and ola (oil). However the Canadians were nice enough to let everyone use the name. Glucosinolates are the hots in mustards but when present in the rapeseed meal have anti-nutritional value in animal feeds. Fouls up the thyroid I think. Oh cute, and I damned sure don't mean bow-legged. :( With a low-low rapeseed everyone gains. You get an excellent cooking oil high in mono-unsaturateds and a high protein byproduct suitable for animal feed. I suspect that the 'stick' machining lubes that were popular a few years ago are simply a soap made from whatever oil happens to be cheap. Twouldn't surprise me. I have a stick of Door-eze for car doors, and that still smells like beeswax its 20 years old already. :) Thanks Dave. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

I use propylene glycol (aka pink RV antifreeze - you can drink the stuff in small quantities) in my bandsaw as a flood coolant and it works great. It doesn't get sticky, it doesn't freeze, and it has a corrosion inhibitor in it. $2.50/gallon in the fall when everyone puts it on sale. My new bandsaw is relegated to wood, and possibly venison.

As I'm not yet 100% with my new Nikon camera, getting the closeups might be fun. The maximum dimension is maybe 3.5cm. Its basically 2 coaxial pipes, with the main air flow coming out between the OD of the smaller one, and the ID of the larger one. The diff is 1/64th inch so it isn't a very big 'leak'. And unless I can find some stronger hose, limited to about 60-70 psi. Clear vinyl isn't a high pressure hose. The oil will come out through the bore of the 1/16 diameter pipe, a pretty good restriction but I've put a needle valve in that line also. That pipe nozzle projects about 30 thou past the face of the brass block I bored to hold it all. These pipes 'nest' so one can get any diameter needed by simply slipping the next bigger one on and sweat soldering, so both lines by the time they hook to the vinyl, are about 7/32.
