The resulting voltage divider equalises the PD across the capacitors. (If you make the resistors equal. :-) Even something like 10k should do the trick, so long as you're not using leaky electrolytics. If they've been on the shelf for a long time, the dielectric can be reformed by applying a low voltage from a modest impedance, before use. (I just use my ancient multimeter, on the ohms range, both 'cos it's handy, and because you can see the leakage current dropping. N.B. On mine you have to swap the leads, because it happens to feed out reversed polarity on the ohms range.) Erik - This SF.net email is sponsored by: Splunk Inc.

[Emc-users] Handwheel overrun
Gentlemen, I saw some behavior I don't like today. When I move the table using the handwheel and have the feedrate override set low I see a rubber band effect. The table runs on after I stop turning the handwheel. I have the jog-vel-mode set true for each axis. The axis moves in the manner I like when I have the feedrate override at 70% or above. As I move the feedrate override lower the rubberband effect gets more apparent. Would it be possible to peruse the code again to see if the accumulated counts can be dumped? Otherwise, the Dahlih, is running perfectly. Clyde had a program incorrect. He gouged the part. The part is a piece of steel. He was standing by the machine paying attention to some other parts. The cutter started cutting and as expected, started making a little cutter noise. When he caught it, the cutter, a 1 inch diameter roughing mill, had cut a slot 1 inch deep and 1 1/2 inches long. I don't know the speed and feed. He was expecting to cut around a circle and remove about .100 in. from the inside of a hole 1 inch deep and 2 inches in diameter. With the extra slot in the part he had to start over. It is sad to say but we cannot charge extra for this type of unintended material removal. My point is the mill and EMC handled the load in such a manner the noise of the cut didn't increase to the point of grabbing the attention of the operator standing next to the machine. I continue to be impressed by how solid and reliable EMC drives this machine. I hope to configure the axis compensation shortly. thanks again for this fine project Stuart - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Question though: Working in a blind hole today, I found the electrode sharpening itself like a bullet, and to get part of the 2nd tap out, (the first one was easy once I figured out I needed more voltage & stacked my battery charger on top of the other supply, which will have to do till the new transformers get here) I've had to replace it it, and clip it back square several times. The bottom of the tap is still in the hole and I don't seem to be able to 'get at' the outside of it while the electrode is still square. I'm getting shorts real easy, like the tap is moving around in the hole, but its sitting solid when I try to pick it. >Real edm systems also filter ( 5 um ) and reuse the dielectric. For >the small amounts you use it is probably a throw away. I made a dam out of modeling clay, about 1/2" high, with a malt straw down the middle, filling it with kerosene and sucking it out and replacing it when the feed rate at 30 volts slows down. With fresh kero I can run down at about .009"/minute. But at about -.6" I'm hitting the wall, it just shorts beyond that point even at .0001"/minute feed. >>> The alum-tap is a really light fluid, maybe just a little higher >>> viscosity that water.

Re: [Emc-users] Interactive machining
Ken, I strongly agree with you, you did a wonderful hack, adding a lot of functionality with a minimal amount of work. It was "the right thing to do", and the price sure is unbeatable :) I learned programming back in 1976 in FORTRAN66 on an IBM 1130. At least, it was a high level language. RS274 is more like an assembler on which we add flow control and macros (this can be very efficient, as does Alan)..., the next step could be to write a compiler (which translate, as suggested by André, some kind of FORTRAN to RS274, then enter the road of structured programming with PASCAL_EMC, then OO, with RS274++ :) Or we can take lessons from the actual trends in computing, and just add bindings and specific classes to an *existing* OO language such as ruby, python, perl... python being a very good candidate. In that case, this will be EMC specific, but that is not a problem as long as RS274-NGC is still supported. It is NOT a replacement, it is an augmentation. Is it difficult, very difficult or extremely difficult to add an NML+HAL library to python?

I've heard of people lapping the rods using Clover lapping compound on a coupling nut. (The long nuts that are used to couple threaded rods together, usually sold next to the rods.) Chuck the rod in a reversible drill, apply some clover, and run the nut from end to end a few dozen times to take down the rough spots.

Re: [Emc-users] Interactive machining
This thread brings to mind that it would be nice to have a "skins" feature. Let's say, ACME Precision, Inc. is a Haas shop and would like to use EMC to convert an old unused Fadal. The person doing the conversion would most likely not be the person running the machine so the operator would be best served by having a familiar (Haas) interface and not have to deal with EMC at all. (On a side note, EMC enthusiasts could collect and trade skins. E-stop ring tones would be nice too. But seriously, skins would be cool.) Kirk Wallace - This SF.net email is sponsored by: Splunk Inc.

Re: [Emc-users] m101 Turret Program
Doooh...I remembered this morning that anything from iocontrol.X is in user space. My original concern stemmed from an application where I was controlling an antenna rotor using "sleep" to control the timing of a 60 Hz two phase signal. The motion would be erratic depending on the system load. The rotor worked fine, but it brought to the fore, the limits of userspace timing. Though, now that I think about it, the timing for the turret is probably much more tolerant. Plus, I'll be adding feedback to compensate for variations (hopefully). I need to get this project done before senility really sets in.

Re: [Emc-users] loading emc-unbuntu
Hello Chris, I assume you downloaded an .iso file? This file is an image of the CD that you want. Many times when you create a CD, the CD burning software just copies the file to the CD as a file. What is needed is for the CD burning software to be told to use the .iso to create the new (boot-able) CD from the information within the .iso file. If you look at a directory of your new disk and only see one .iso file, then you need to create another CD using the "create CD from an image file" feature of your CD burning software. This link might get you started: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BurnIsoImage Kirk Wallace ~~ On Tue, 2007-08-21 at 13:01 -0400, Chris Mason wrote: > I have downloaded the software on two different cd’s.

Re: [Emc-users] Foam cutting configuration
> Please keep us updated about your progress with XYUV. > > (As far as I know, your foam machine is another milestone for EMC2.) > > Chris Well, I got everything up and running last night, and after playing with my g-code for a bit, and trying to figure out the right combination of feed rate and wire temperature I managed to cut a reasonably respectable airfoil core. Some pictures of it are here. http://i14alberta.ca/gallery2/main.php?g2_itemId=1014 The only real issue I had was that I was generating x,y positions for the foil shape in relation to the chord of the wing. On the leading 20% I was creating them at 1/1000 of the chord length intervals to get a high resolution shape, and over the trailing 80% I was using 1/100 of the chord length intervals. The first couple of cuts I was using a chord length of about 100mm, meaning that my g-code statements around the leading edge where about 0.1mm apart or less, which caused the feedrate to slow down for some reason, which caused too much heat to build up in the leading edge. I re-processed the g-code to scale the chord up to 200mm, and remove any statements that where less than 1.0mm from the previous point and that seemed to do the trick. I am using 20ga nichrome-80 wire (about 2.5 Ohms/ft) and found so far that using about 2.2 amps of current and a feedrate of about 150mm/min gave pretty good results. My guess is that using a slightly higher temperature and faster feed rate would be better, but I need to lubricate the machine and fix some wobbles/stickies in my lead screws. I am using standard hardware store threaded rod, with the standard coupler nuts. Any idea what the best way to lubricate them is? I bought some lithium grease, but have not applied it yet. Next thing to do is to charactarize the kerf width and try some tapered sections. I will take some pictures of the machine when I get a chance and post them in the wiki.

Re: [Emc-users] tool turret ideas
Thank you Chris. Sometimes these little bits of information make all the difference. I did not get this searching linuxcnc.org so either, I did not search well enough, or I need to put the information on the wiki somewhere. I hope to be able to document the whole HNC conversion in a month or two, so that the next person will have an easier go of it. I just went back and did a search for iocontrol.0.tool and found: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMCMOT_And_EMCIO_HAL_Interface ,so it is documented. I now remember reading this page a while back, but it had no meaning at the time. Now that I have used HAL a little it is making more sense. (It is plainly in the Integrator,s Manual too. I need to reread the manuals.)

Re: [Emc-users] Interactive machining
I disagree with the defenders who say it is not a kludge. It is a kludge. It was when I wrote it and it is now. The reason that these features must begin with an o-word is very simple. It made it easier to change the parser. The code simply tests if the line begins with an o-word. If it does, it calls a function that processes o-words. The change was simple and effective. I wrote that set of changes (call, if, then, else, while, return, endsub, do -- plus the expression changes -- eq, ne, le, lt, gt, ge) in about a week while I was on vacation. It IS free. If you don't like that syntax, please feel free to not use it. If you prefer a different syntax, please, please feel free to add it to the interpreter. I won't take offense. Really, I won't. It is a kludge. One of my better ones, I think.

The typically have multiple sizes of brass tubing that just slip inside each other. The fancy stuff with internal structure is available off the web. IV tubing should work for dielectric delivery if it doesn't curl up and die from the solvent. Being able to flush a cavity in EDM is VERY important. Not much else will do as much for erosion speed. Real edm systems also filter ( 5 um ) and reuse the dielectric.

In order to machine a new simple part, I often only have to write a few lines of code to call the appropriate macros with the correct parameters. So to drill a hole requires one line of code, a pocket requires one line of code, the outline of the part can be one line of code if it is a rectangle. If I want a bearing pocket with a through hole it requires two lines of code. I could write a macro for surfacing a rectangular area that would only require one line of code to call. I have a bunch of variables at the start of the program that allow me to change the diameter of the bit that I am using, and set the machine offset for the part's origin, and the thickness of the material and the location of the zero point for the z axis. I can also set the step down with the variables. What does this all buy me? Well I know the routines work, so I don't have to spend a lot of time debugging. I also know their limitations, so if I need to do something new and unique I can decide whether it should be generalized as a modification to my starter file or just a quick and dirty routine for that job.

Yes, I never did get Axis A to work in the simulator last week when I was trying to help Ian Wright.

Re: [Emc-users] Jog speed vs. G0
Hello Gene The rapid velocity set for any axis in the ini file is the max velocity that a properly executed motion command can achieve. Feedrate override greater than 100% does not increase that speed. Commanding rapid for more than one axis at a time will result in greater speed along the diagonal. There are some issues with g0 for a rotary axis and a few issues between max vel in the trajectory planner and max vel on each axis.

I thought it was bad when I did that task (previous two elections) +- at that time they put 50 or so names per page, and it took about a dozen pages to get everybody. One page per letter is worse.

Re: [Emc-users] voting
Stuart, everyone who participates on this list and/or the emc-developers list is eligible to vote. That being said, due to a mistake I made, I've created a little mess. Let me explain. I generated the list of emails to give Michael by copy/pasting the list from the web-based administration interface for the emc-users and emc-developers mailing lists on sourceforge. This list has a different web page for every letter/number of the alphabet, and I copied once for each page. What I missed was a link at the bottom on SOME of the pages for letters that had too many subscribers whose emails start with that letter. In those cases the sourceforge web interface breaks the letter into two or more pages. For those letters, to my great dismay, I missed some subscribers. There were approximately 148 eligible voters I accidentally left off the list. These were people with emails starting with the letters A,C,D,E,G,J,M,P,S. With the 14% response rate we received this year, this means we are probably missing about 20 votes. Yours is one of them. I've talked to Stephen and Alex and I think we all agree that we should send ballots to these missed folks and extend the voting deadline. I see a few other options but they don't seem as good.

Re: [Emc-users] voting
Gentlemen, My question "Who votes?" was not a cynical, rhetorical, apathetic comment. It was a legitimate question. I saw no ballot. I saw no email. I did not have the opportunity to vote. I will now expand on the first question. That way there will be NO confusion as to the meaning of or the reason for my question. What group is quailified to and has permission to vote? My vote wouldn't have changed the outcome but I WOULD have voted if given the opportunity. For what it's worth. Is that a more clear question and statement? thanks :( Stuart - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Correct me if I'm wrong guy's but I believe G0 speed is the 'default" settings in the .ini file. The maximum jog is I believe of a multiplier that is usually set to something in the 1.2 area, and effects the range of the feed override slider. Jog speed may also be a function of the MAXVEL settings in this file. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Unforch, Stuart, the micromill has no facilities to feed coolants through a mounted bit. I'd assume also that your machines maker also supplies the expendable electrode at a price.

ATM I'm using 3/32 brazing rod, but the thought has crossed my mind that a 3/32 drill bit, with its flutes, might provide passage for flushing air if a wd-40 nozzle tube could be aimed at the work/bit junction such that a blast of air would be directed to the electrode face as a flute went by as it turns a couple hundred rpms. Down one side and up the other. This will require a re-mount of my current air blast as that's mounted on the head and this should ideally be fairly fixed so it could maintain its aim. With my current compressor, there will be a certain amount of water in the delivered air too, and it doesn't seem to help a to drain the tank, 5 minutes later it has water in the air again. I think its un-avoidable unless one is willing to purchase and maintain a silica-gel dryer, which with the flow a day this would require, would also need about a 4 hour bake cycle a day. PITA... But the conversation about this is an ongoing idea exchange, thank you very much, Stuart. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Re: [Emc-users] Interactive machining
Ray, Fanuc used the O word to be the program name or filename and one could be called and used by another. I could possibly find an example of the advanced (advanced as per about 10~15 years ago) capabilities of the Fanuc I used to run if you wish. The versions of the controls on two of the machines were an 11m or something like that on a horizontal machining center and a Secos II (same as a Fanuc) on a vertical mill. both were Hitachi Seiki. Both worked very well.

Re: [Emc-users] Interactive machining
Binding EMC2 to a *real* language seems an *excellent* idea to me. RS274 is an antique language. Adding O words, named parameters and special comments, although very useful when nothing else is available, is only a kludge... The only advantage of RS274 is that it is normalised, and that many CAD systems generate code for it, so that is the way to go for complex parts. But, for small jobs like surfacing, pocketing or making holes, I found that creating gcode is longer that doing the job by hand. Mach3 has wizards for common tasks; the same could be done with EMC. Being able to create quick and dirty interactive programs for small jobs would be a BIG bonus for me. I am mostly fluent in C, but learning *yet another modern OO-oriented language* plus NML and HAL commands is not a big deal. An important point is that we must not shutdown (at least) axis, (and possibly) tkemc or minimill (my preferred interface...) when running a script; I think that NML and the modular structure of EMC allows for this.

Re: [Emc-users] Encoders with steppers
Thanks to all who replied for the very good information. To summarise: - Adding encoders to steppers can be done, and HAL has all the components needed. using encoder-PID-freqgen creates basically a "servo system with steppers". Freqgen has parameters for capping velocity and acceleration. - But this means tuning PID loops, which is not a trivial task, especially with the non-linear characteristics of steppers (mid-band resonance...) - The index pulse of the encoder can be used as a precise home switch. - But because of the torque/speed curve of steppers (different from servomotors), the behaviour of the system when pulses are missed is *difficult* to master at best... So it seems that the benefits are not worth the trouble and price of adding encoders, and so I will stick with my bare steppers which work *very* well.

It is not the time/place to be dogmatic as I cannot show a demonstration, but there *are* two aspects I think Flash offers (a) A framework for design of very interactive graphic interfaces (e.g. the label for an Axis DRO that opens up to show scaling, offsets applied etc. when it is clicked) integrated with (b) A powerful and well structured script programming language.

[Emc-users] tool turret ideas
Kirk When Emc gets a T word it puts a true on iocontrol.o.tool-prepare then expects a true back on incontrol.0.tool-prepared.

Unfortunately, I know next to nothing about Classic Ladder, so I tend to use what I know. I have been trying to figure out if I should learn Classic Ladder, but it seems to me, that PLC's where a way to bring the old world of physical relay systems into the computer age.

The lathe turret tool change is not like a mill tool change. No interaction with the spindle is needed or wanted. All that happens is the turret rotates to expose the needed tool. So I'm thinking that m6 will not be used at all. Only the t word is needed, but I have not been able to find out what t actually does. (P. S. I forgot about the tool table. m6 may be needed to activate the current tool information.) Plus the actions taken when the interpreter reads a t word seem to be compiled in EMC, so are not subject to change, or at least for me at the moment.
