Re: [Emc-users] Incorporation Donation [Was: Re: What's coming in manufacturing]
Hi I think EMC2 can not be compare to RED HAT software. After price for Red Hat will be too high computer mfg will switch to UBUNTU or next in line Linux distribution. Software EMC2 by them self doesnt have whole much volume. Use EMC2 to apply to each particular job retrofit real machine or build new type of machinery is a core for making profit from EMC2. If one want to learn how to use EMC2 it should be free, but many companies do not want to learn anything! That companies want to job to be done! And here where is money to be made. I think on www.linuxcnc.org need to open special section where one can find the list of companies that ready to take any complicity job in applying EMC2 to particular job. Many small tool mfg will use them, machine shop will know to where to look and to who to call. EMC2 retrofitter can become good brad name. That what I think Thanks Aram John Guenther wrote: For whatever my opinion may or may not be worth, I think well enough should be left alone. EMC2 seems to be moving along just fine without the 'commercial' headaches! It seems to me that EMC2 is being developed by some dedicated hard working people that are more interested in making it right than in making money from it. Maybe some day development can split into a quasi commercial product and an open source product much like the Linux world but I am not sure that day has come yet. Heh. Thanks for the sentiment. Look at the Linux commercial model: The kernel itself is completely free. Some companies hire people to make changes they think are good. If the community (ie, Linus) thinks it's good, it gets incorporated into the mainline kernel. If not, the company has to maintain their own patches to the kernel. So a company like RedHat then charges people for documentation, support, and packaging to pay their programmers. A model like that could work fine for EMC2, except that we don't have anywhere near the userbase of the kernel itself. Luckily, the customers of RHEmc megacorp are used to paying a lot more for their software than the average joe (who thinks it's free with the computer), so there's room to hire people with a much smaller customer base. It's still quite iffy, as Alex pointed out.

[Emc-users] Z axix direction problem
Hi I have problem with interpretation of G code. Basic problem is with Z axis. I set G55 right on the face of part. Start with G54, than G55 X0 Y0 Z0 When machine reads Z 0.1 (positive) volume machine moves from G55 plane away from home. When machine reads Z -0.3(negative) volume machine moves from G55 plane to the direction of home. My program created with CAM based that positive volume will move machine closer to home and negative volume moves machine away from home position. Did I explain problem? If so where is the solution?

Thanks aram I have verified that saving a Text or Text Encoded file from openoffice 2.4 is incompatible with emc. openoffice writes something at the beginning of the file called a unicode byte order mark; don't worry if you don't understand what that means, but *do* understand that openoffice will apparently not save files in the form required by emc. Use a text editor (not a word processor or typesetting program like openoffice write). gedit is a text editor that should be installed on an ubuntu machine, and many people use it successfully to write gcode programs.

That isn't a technical issue - you only need the two - but it just adds to the confusion. Technical problems: you have a max velocity of 1, which means 1 inch per second. You have a scale of 4, which means 40,000 steps per inch. Combined, that means 40,000 steps per second. To do that, you would need a base period no longer than 12500 nanoseconds (which is very fast). You have 14000 nanoseconds (which is also quite fast, but not fast enough to get the speed you are asking for). I think you'll need to lower your top speed. i just interesting, is pulse per revolution same as steps per revolution (x something to get steps per inch)? can i say that 1 step/pulse = 0.3125 nanoseconds and when it comes close to 12500-13000 is is too fast? thanks Jeff Epler tried running the config, and got a following error, because of the speed limit, and/or an acceleration limit.

Thank you Aram The traditional way to machine short, large diameter parts, is with a T-Lathe. That has the bed at right angles to the spindle, a large diameter chuck or faceplate, and no tailstock. For example: I just realized that a vertical spindle lathe would also work, and might be easier to load and unload, since gravity would hold the rims in place while you center them up. The pictures below are much larger and heavier than would be needed for bicycle wheels, but they should convey the proper idea. http://www.shzhoule.cn/english/admin/upload/2007830145232661517.jpg http://img.alibaba.com/photo/50995654/Vertical_Lathe.jpg As with the T lathe, if you don't need to machine the center, the X axis can be much shorter - you probably wouldn't need the bridge shown in the photos.

[Emc-users] Putting Encoder on AC servomotor???
Hi I am looking for more info about why I can not take out encoder from AC servomotor and put another in? I want to try 1000 000 pulse encoder. If I buy it can I install it my self? Encoder counts revolution, so why I can not remove and put it back? I look on google about that but can some one send some link from web to refined explanation, that can answer that question? Or what should I have (manual how to do) to install encoder my self? I talk to FANUC people and they say that 16 000 000 puls per rev on the motors already. FANUC present today to us 30i controllers with a lot of new things, 5 axis probing, dynamics plan, etc. I do not think that EMC should chase down FANUC in this case because there are different target markets. aram - Check out the new SourceForge.net Marketplace.

Re: [Emc-users] Putting Encoder on AC servomotor???
Hi Servo Dynamic told me that have encoder with too much resolution is not help because drive will not be able to process or use too much pulses from encoder. Are there a MAXIMUM limits of pulses from encoder? can i joint to shaft of my motor another encoder -High-resolution http://www.opticalencoder.com/pdf/CP-850-950-HHC.pdf and connect that encoder to EMC2? forget about encoder on the motor? Hi Aram The bad news is that if you attempt to change encoder you will find the motor will no longer work. The good news is that you can simply add an encoder somewhere in the drive chain and EMC will be pleased to use that rather than the motor's encoder. There have also been a bunch of patents issued and reports released of projects that multiply the pulses from an encoder. You might dig a bit and find such hardware/software schemes. Be sure that you put the multiplier after the motor drive rather than between the motor and drive.

Re: [Emc-users] Harmonic gear and EMC2. ????
Hi I thing we uncovered all potential problem for slow speed machine. Here a will use more refined numbers and it looks more close to real situation. Minimum counts to controller about 30 pulses per second. Or 1800 counts per minute. One revolution is 8192 pulses. So, per minute I will have 1800/8192 = 0.22 rpm. 0.22 rpm is equal to 80 degree of revolution per minute. 80 degree per minute is a min speed to AC servo motor to be stable. ,, Machine moves 0.00025 per minute what is 0.45 degrees per minute. ( ball screw 5 rev per 1 inch = 1800degree per 1 inch of travel) So, motor can rotate 80 degree per minute but machine needs only 0.36 degree per minute. So reducer must accommodate that, 80 /0.45 =177 ratio. Closest ratio of standard harmonic reducer 160 and it is close. AC servo motor can spin up to 7000 rpm. So, min feed is 0.00025 per minute with 80 degrees of rev per minute, And max feed will be 7.875 inch/minute per with 7000 x360 = 216 degrees of rev per minute. I think it is reasonable range of feed to travel. So, one stage of harmonic drive with ration of 160:1 will be enough to satisfy grinding process. aram John Kasunich wrote: Kenneth Lerman wrote: A simple solution is to use a dual drive. Use a course mechanism with long travel for course positioning and a fine mechanism with limited travel for fine positioning. The fine mechanism has a large mechanical advantage and can use a smaller motor and driver. Of course, some sort of clutch mechanism could be used to allow switching between the course and fine speeds. You might be able to avoid the clutch as well. One possibility would be to stack a very high resolution slow stage on top of a fast coarse one. With the right speed reducer, I think these extra complications are not needed. The problem is that asking a motor to give smooth motion at a speed of a few degrees per MINUTE is just too slow. But, a servo motor can also run at pretty high speed. So, a modest speed reduction between motor/encoder and leadscrew should satisfy both the slow and fast requirements. The speed reducer must be stiff and backlash-free, which requires a higher class of unit. Either a worm drive or planetary would work, as long as it was designed from the ground up for zero backlash. A problem with a worm drive is it has sliding friction, and will wear. There is a new style of zero-backlash planetary drives that use slightly offset pins on the planetary carrier, causing it to spring-load the gears. I'm guessing this is a patented technique, and so there's only one supplier for a few years. You could also do things like having the fast motor turn the screw, and the slow motor turn the nut with a worm gear to increase the resolution and decrease the speed. In this latter case, the stiffness of the fast motor will be an issue, even though it isn't turning. You haven't answered the question of what type of mechanism you are planning to use to provide smooth linear and rotary motions at this slow speed. I think Ken has hit the nail on the head here. At very low speeds, it is very hard to get smooth motion. You are more likely get stick-slip behavior, where the motor turns a little but the table doesn't move. The screw and other parts deflect until they build up enough force to overcome the static friction and start it moving. As soon as it moves, the dynamic friction is much lower than the static friction, and it moves farther than you wanted it to, then stops. And the whole cycle repeats... The individual movements are tiny, but at the extremely slow speeds you are talking about, stick-slip is more likely to be the limiting factor than your encoder resolution. Yes, you need all rolling elements, leadscrew, slide, etc. to combat this. Gearing down does not help - the issue is the flexibility and friction of even the most rigid screw/nut/bearing combination. At these scales, you almost have to think of the metal parts as if they were hard rubber. Sliding ways are usually the worst choice for stick-slip. Rolling element Linear bearings are better, but they are not very happy in a grinding environment with abrasive dust. Depending on the loads, you might want to consider air bearings. They do not suffer from stick-slip, and to some degree are self-cleaning in a dusty environment. One of the regulars on IRC, who uses the name toastydeath, works (or worked) for a company that makes air bearings, and may have some suggestions. Air bearings are insanely easy to make, although getting just the right geometry to prevent oscillations is slightly tougher. Really, you can make surprisingly good air bearings with a drill press, a block of aluminum and a surface plate. You drill a hole in the block, then make a slight relief in the center of the block, and lap the rest of the block flat with fine sandpaper and the surface plate. Apply air pressure to

Re: [Emc-users] Harmonic gear and EMC2. ????
travel at feed 0.001 will be geometry of 1 inch end mill, with length of end mill 4 inch. 0.001 /min it is cutting feed only. rapid to new position will be much faster. It is my understanding that in a grinding machine: 1 -- Cutting forces are low. 2 -- Backlash is generally not important. 3 -- Smoothness of motion is very important. I would suggest that before you worry about how to drive the components in slow motion, you should tell us how you plan to drive the components smoothly. What are you going to use for linear (for the linear axis) bearings and what will you use for rotary bearings? Stiction can be a major issue. Air bearings come to mind as a possible solution. Regarding the feed rate of .001 inch per minute and the distance of 12 inches. Am I correct in assuming that you would not be traversing that length at that feed? If that is true, what is the actual distance that has to be traveled at that rate for any given pass. A simple mechanism to provide very high reduction ratios is the differential screw. It does, however, have a limited range of motion. It sounds like an interesting project. Do you have any sketches showing the general layout?

[Emc-users] Harmonic gear and EMC2. ????
I am building CNC tool grinder. The feed for tool grinder should be from 0.00025 to 0.001 of the inch per minute. The servo motor must perform at this feed perfect to make a good grinding job. I will use direct drive and my ball screw has 5 pitch per inch. So talking in degrees, 5 times 360 = 1800 degrees of revolution of motor to get 1 inch for linear motion. To get 1 inch need turn 1800degrees/minute of motor. To get 0.00025 need 0.45 degrees/minute of motor. Is this too slow? I think so. The one solution is to take high end controller and large AC servo motor and that is expensive. Jon Elson said about harmonic drive. I found here www.harmonicdrive.net That gear can reduce up to 1 to 160. If I will put two side by side, it gives to me 25600 to 1 reduction. So 0.45degrees/minute times 25600 equal 11520degrees/minute, or 32 revolution per minute. 32 revolution per minute is good range to any AC servomotor and with 8192 pulse per revolution drive and EMC2 will have enough pulses to be accurate. All harmonic drives have 0 backlash. One piece for NEMA34 cost $1500 and per axis it is $3500 with special plates etc. 5 axis is $17, 500 is to gears a lone to make good CNC tool grinder.

Re: [Emc-users] Harmonic gear and EMC2. ????
accuracy of machine is important but feed should be low enough to grinding wheel can do the job. grinding of solid carbide is slow process. screw may be 0.005 inaccuracy but feeding need be very slow to do the grinding. aram Hi Aram I don't think it's the diameter that's important (unless the forces on the screw will be very high). The important specs have to do with screw pitch error, preload on the ballnut, and also the end bearings. A good screw will have maybe 0.001 error over 1 foot, the best I saw with a web search were only 0.0005/foot. To get the kind of precision you're looking for, you will likely have to have very good temperature control (like coolant through the screw), do an analysis of the amount of flex in the shaft due to loading, etc. I think the precision of the mechanics will be a much bigger problem than moving a motor at low speed.

[Emc-users] 2x 5i20 cards, how to set additional axis
Hi I build system with 2 5i20 and 2 analog cards. I am looking for direction into to activate 6 axis. I did add axis last year with help of Steve. This time I will document every single click of how do that because it will be part of my theses for my school. Anyone who do not like me personally please do not respond!

Re: [Emc-users] EMC Fest 2008
Hello! What did I said bad or what recommend bad/stupid ideas? If one got happy when I burned down my encoder with 24 V, thank you to saying that. It really looks educational and helpful. What did I said or proposed was wrong??? Sorry if I cause trouble. Aram Ray Henry wrote: Sounds like you are saying you want me not to teach this class. (off list) Hi Ray: Aram is being Aram. He was at least year's workshop, and he is enough to try anyone's patience. 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
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. Thanks Aram 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.

Hi I think that MESA Electronics should be interesting in developing software part for EMC2 build on 5i20, 7i33 and 7i37 boards, to plug and use MPG4 pendant. That will promote sale of 5i20, 7i33, 7i37 boards. MESA electronics electronics company and for them to open MPG-4 and develop software that enable to DB25 from MPG-4 to connect to MESA Electronics breaker boards also with DB25 connectors.

Last year Jon Elson teach about tune up. Stuart Stevenson help with Linux part. I am sure that it will be good for the CNC Fest to organize class where one can bring the problem and solve the problem and everyone can see the power of the CNC Fest. I am sure good class organization will make more incentive to more people to come to CNC work shop. I am wrong? I have topic for class, program MPG-4 pendant and make it fully functional. I think many will be interesting to see how it can be done. If any preoperational work can be done, please let me know.

Re: [Emc-users] SATA hard drive
yes it was problem in BIOS sttting.

Re: [Emc-users] CNC4PC +EMC2
Hi I am sure that machine shop people are different people and standard pendant must be there and also rigid and robust system is important. One glitch is software may cost to machine shop $ 100 K as a scrap part. Involving 3rd party software such as X-key will contribute a lot to glitches one after another in order to latter offer a lots of solution to sole those problems. I am sure that it is important to keep system simple.

Re: [Emc-users] Very low PRM system.
Hi I want to describe my understanding for low feed system. I will use direct drive mounting and that mean 5 revolutions for 1 inch of travel per minute. 5 revolution times 360 degree is 1800 degree per 1 inch per minute. 0.0001 travel per minute means system will have 1.8 degree per minute. My system generate 8192 pulses per quadrate so 4 times 8192 =32768pulses per 360 degree of revolution. So, if I divide 32768 by 360 I will have pulses per 1 degree of revolution, = 91 pulse per degree. For 1.8 degree per minute I will have 1.8x91= 163.84 pulses per minute. Finally, in the case of feed 0.0001 inch per minute I will have 163.84 pulses per minute. Per second it will be 163.84/60 = 2.731 pulses per second. So, is this enough pulses? If I put 1250 K encoder, will it solve the problem on the way in obtaining stable 0.0001 per minute feed? Is 1250 K pulse is it per rev or it is per 90degree or revolution? Thanks Aram Hi Aram, I did find a high res encoder at 1250K counts/rev. I'm not really certain that is ppr or in quadrature.

If you really need .0001 Rev/Minute, that is 32768 counts * .0001 = 3.3 encoder counts/MINUTE, or 18 seconds between each encoder count. You can't get smooth motion like that. Of course, .0001 RPM x 5 TPI on the screw is a movement rate of .2 IPM. Do you truly need it this slow? To get smooth motion, you really want an encoder count rate of maybe 15 counts/second, or even better, 60. So, for 15 cts/sec at .0001 RPM, you need 15 * 60 * 1 = 9 000 000 counts/rev, or 2 250 000 pulses/rev. This will be a pretty expensive encoder. (Multiply by 4 for 60 counts/sec.)

Re: [Emc-users] X11 file problem/HELP
Hi Thanks Ray, I want to say that when I install new UBUNTU on other hard drive on the new box, computer start and UBUNTY was working perfect. So I think I will move HD back to old box, copy EMC2 PID and tune up parameters from old HD and put it on other HD with other seting UBUNTU on new box. It is easy to me, I think. aram Hi Aram The reason we had to change the xorg.conf file was that the installer program did not find a proper one. I do seem to remember using vesa as the definition for that box. This (vesa) is a very common driver for on-board video displays. I don't recommend moving a hard drive to a new box unless you've already installed on that box's own hard drive and the swapped one is just for extra stuff. There are way many other things different between motherboards and the boot hardware checker is not always able to find all the things it needs for the new. If it were mine, I'd put the hd back, find a usb stick and move the files I want to keep to that and install Ubuntu in the new computer from a CDROM. My second choice would be to start a live session on the new box from a CDROM and look in /etc/X11/xorg.conf and see what it is using for a display driver. If you have the old hd in place during this live session you could mount it and edit its xorg.conf to match the one found in the live session. You would be changing the file in something like /media/hda(1)/etc/X11/xorg.conf. Make a backup in the same directory with a name that is easy to remember and change back because you may well be working in a text mode editor like vim. My latest install of the 8.04 beta also failed to find the right display driver. I was getting some really strange display issues with the Axis gui. We sorted it out with folk on IRC and I'm as happy as a Rayh --- [EMAIL PROTECTED] wrote: From: [EMAIL PROTECTED] To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Cc: Enhanced Machine Controller emc-users@lists.sourceforge.net Subject: [Emc-users] X11 file problem/HELP Date: Tue, 22 Apr 2008 00:00:53 -0600 (MDT) Hi Let me describe my problem.

Re: [Emc-users] PID-tuning
hi you said that Clearly higher feed-rates are more difficult for the PID loop. what about tunup problem with very slow motion? i mean feed with 0.0001 per minute. i use ball screw 5 mm per revolution thanks aram Hi all, I got my x-axis servo motor mounted today and ran some tests. There is a video and some hal-scope screen shots here: http://www.anderswallin.net/2008/04/x-axis-test/ This is a system with no motor current, motor voltage, or velocity feedback. An m5i20 generates PWM output for pico-systems DC-brush amps and 4000 pulse/rev encoders provide feedback. This might make the system a bit different to tune from other systems which run another loop on current/voltage/velocity. I found FF1 worked quite predictably and reduced the cruise-phase error to very little. Only P and FF1 was needed for that. (2nd pic on page) Then I added a lot of I-gain which helped a bit for the acc/dec phases. With FF2 I became confused on a higher level (3rd pic on page). It seems to either fix the acc. phase or the dec. phase but not both. The last pic shows moves at different feed-rates. All of them show around 16 to 25 count spikes during the acc/dec. phases. Presumably at the moment when acceleration changes and jerk is infinite.

[Emc-users] 5I20 connection to 7i33/7i37
Hi I want to ask question about 5i20 and connection to 7i33 and 7i37 boards. Are there limits on length of cable that connect 5i20 to other boards? Can I use cable that 2 or 3 feet long, and will it effect over all performance of system?

Re: [Emc-users] Jogger wheel + switches
Hi
I have provlem with www.CNC4PC.
ehere is those company?
Are they in USA or where?
Every US company has a phone to call and ask questions CNC4PS doesn't.
i send e-mail with same question and he send me phone 772-6215525 number
but nobody answer those phone.
Does any one purchased any think from cnc4pc?
thanks

When it comes to electronics I need all the help I can get. So the MPG
puts out 4
pairs of signals and the LM399 converts that to 4 outputs? Lots of
googling going
on... and EMC needs? I'm just looking at a MPG spec sheet and they only
have 6
connections so I assume one is ground, one is power in and the other 4
are the
signal coming out. Now I'm really confused. The LM399 has 8 inputs and 4
outputs.
Can you explain just a bit more for me please.
The cnc4pc jogwheel has A and B outputs ('single-ended' if you like).
These plug directly into the A and B channels of a hardware encoder
counter (m5i20, pico-systems, vital, etc.).
If you don't have a spare encoder input the jog-wheel could be read by
two general purpose I/O pins (e.g. parallel port) since you are not
likely to spin the jogwheel very fast.
Some jogwheels use differential signals, which means instead of just the
A and B signals you get A+, A-, B+, and B-. If you have I/O to spare you
could wire all four of these to EMC. If you want to condense these four
into just two A and B signals you can do that with an IC. I did that
with a DS3486.

[Emc-users] Jogger wheel + switches
Hi I think in order to EMC2 becomes more friendly to use on the shop floor need implement Jogger wheel. Many times list was back to talk about jogger wheel but problem still there. Jogger wheel is very important with switches that switch between axis XYZAB and changes increments from 0.0001, 0.001, 0.010 and 0.100. Any commercial or better to say real implementation of EMC2 should have basic jogger wheel with switches. So my question is it possible to make standard software inside of EMC2 that uses 4th connector on 5I20 and some kind standard board like MESA Electronics made breaker board for axis motors. I think most jogger wheel uses 6 connectors. Thanks aram - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] tool length compensation
Hi Dynamics tool length compensation for 5 axis in 3D world much complicated. First, tool compensation for 2 axis include touch with probe corner of the table and controller calculated rotation only one axis B that touch table with probe to define Z and it will compensate to tool length. For 5 axis need move axis B, C or A, to make targeted surface perpendicular to the probe and than everything same as for 2 axis routine for tool length compensation. Thanks Aram On Fri, Feb 29, 2008 at 02:51:20PM -0600, Stuart Stevenson wrote: Gentlemen, I am installing EMC2 on a Cincinatti 5 axis. This is sooner than I had planned. The timeframe is compressed. I work good under pressure. It is usually caused by procrastination (mine). This is not the case this time. I need to get the machine running by Friday of next week. Any and all help/comments/opinions will be greatly appreciated. The 5 axis tool length compensation is implemented with G43.1 instead of G43. This is no problem whatsoever. This is like the Fanuc and Haas controls. I would like to use the H number from the tool.tbl file with the G43.1 in the same manner as the H number with the G43. I grepped the directory and didn't find any reference to how the G43 and G43.1 were implemented. Where would I find the code to change the usage? thanks Stuart You misunderstand how G43/G43.1 work. They do not work differently for multiaxis machines. The tool table works as usual with G43 H_. G43.1 lets you specify the length directly in the gcode (G43.1 K___) and it sounds like you will not use this. The actual difference with the 5 axis kinematics machine is that you should specify [TRAJ]TLO_IS_ALONG_W=1. Then when you use G43 H_ or G43.1 K___, the length offset, no matter whether it comes from the tool table (G43) or gcode (G43.1), is applied to the W axis. The only thing your cam needs to do is move the W axis (G0 W0) so the length offset gets applied. Chris - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] DaDynamic compensation.
Hi Stuart I do not know how difficult it will be to te code for 3D compensation in 5 axis world. I want to say how it looks to me. 1. On solid model need to identify equal size triangle with 3in each a side. 2. Machine should move ahead and heat part in designated area of part or fixture. 3. calculation must take a place that should calculated of how much need to rotate A axis and axis B to make plane on part perpendicular to machine tool- probe. 4. move that A axis and B axis. 5. move probe ahead heat a part again in the area right on the plane where those imaginary triangular located. That will need to find Z distance. 6. it be nice to have a hole on part (1 inch dim) or on the fixture to pick X and Y, or some tabs to get and position X and Y axis. And we can call all that macro M. Call M and it will dynamically compensate part and after that cycle can begin. This is good option but I want to have AND and not OR. I mean besides macro M it be nice to EMC2 controller send data to computer terminal that should reprogram regenerate NC code and send it back to EMC2 controller. Why I think it is important? Because NC terminal can not only position AB Z XY axis right but also recalculate new path in regards to tool profile wear, such as nose radiuses, tapers etc. What about much more complicated probing on back side? What about probing complicated surface that had been just cut and determine if it needs recut or not? I am looking on probing from large scale machine shop that will have many demands for probing that not address at this time at all. Using seamless connection between computer terminal and EMC2 controller open much more opportunities for digital manufacturing, remote control of manufacturing-machining process that becomes more and more important. I think I can better explain what in my head over the phone rather in writing. Thank you, aram Aram, Hi Stuart I am very interesting in dynamic compensation. You say everything is possible but where it all any manual or list of how do that? Can I call directly and talk and say all what I think that EMC2 should do? Thanks aram The 5axis choice in emc2-trunk is shows dynamic compensation. The kinematics uses two different tool lengths from the program. The kinematics uses a pivot length from a variable in the kinematics file. The program's gcode command is the shape drawn on the screen. The machine movement is very different than the programmed shape. I don't see anything in the manual. I have never added anything to the manual. There is not a better time to start than now. I will try to work on it. I modified a kinematics file to use parameters from the .ini file. This allows the integrator to put the manufacturing/assembly errors from the rotary tables into the parameters. The kinematics file then uses those values to calculate the XYZ correction to keep the pivot length in the perfect spot as the rotary tables move. The kinematics file assumes the rotary tables carry the tool in a gimbaled BC arrangement on the end of the Z axis ram. This could be modified to compensate for any arrangement of rotary table on any machine. Chris Radek has done some of this on his machine. Have you seen his videos? Chris Radek wrote a kinematics file to rotate the machine motion in the XY plane. This is a template to use. I can see how to modify it to allow 3D rotation of the machine motion in the 5 axis world. AND, if I can see how to do it then it would be child's play for a C programmer. I am a C neophyte. I will be working on a kinematics file to do 3D rotation. I just purchased a Cordax CMM. It is a very old manual machine. I want to put EMC on it and use it as a CMM in my shop. It is not functional now with the Bendix control. The Bendix control has quite a number of functions. We are working on the control. We will do a shotgun approach and replace all the electrolytic capacitors. Then we will use a scope to adjust the lissajous circles. (here I am talking as if I know something) (the only reason I know anything like this is there is a couple of electronics guys here). As this is a very old control I want to replace it. I only mention this because I will need to be able to do the 3D rotation to use EMC as a CMM. 3D rotation will also apply to the 5axis probing and compensation you have talked about. This has not been done, AFAIK. The only reason it hasn't been done is no one has taken the time to do it. It is very possible. My personal cell phone number is 316 258 0953. I will be more than happy to talk with you (or anyone else) about what you want to do. Sometimes a phone call will clear things up a lot. The only problem with that is there is no help from anyone else. I like the user's list. The help is incredible. The ideas are amazing. thanks Stuart - This SF.net email is sponsored by:
Re: [Emc-users] Dynamic compensation.
Hi Stuart I am very interesting in dynamic compensation. You say everything is possible but where it all any manual or list of how do that? Can I call directly and talk and say all what I think that EMC2 should do? Thanks aram I think that EMC2 can become industry standard if it will oriented to the shop floor needs. I want to talk about of concept ?idea new requirements to EMC2 as I can see. My point of view as a employee of big machine shop. 1. EMC2 must be able to do 5 axis dynamic compensation. I think it is self explanatory. EMC2 should be able to use probe to heat the 3 points create plane square the machining axis accordingly and recomputed 5 axis path. Let me talk about. As right now many machine can do X Z and B axis dynamic compensation. Very view absolutely new machine can do 3 axis dynamics compensation. None of machine as I know can do 5axis dynamic compensation. How to do this? One way is to continue increase capability of controller on machine. Right now controller on machine can do B axis skew and move X and Z axis. What about move same direction? Add A axis skew and move XY and ZY axis compensation. That way will increase cost of controller, make controller more complicated and less reliable. I think it is wrong direction! Here is right direction as I can see. First, EMC2 is extension of CAD/CAM terminal. How it can be used in case of 5 axis dynamic compensation? CAD/CAM direct tool ?probe to the points on the part/fixture to heat or probe out. I recommend that after probe heat a part/fixture signal from probe must be sent to CAD/CAM terminal. CAD/CAM terminal will much faster recomputed new NC program and load again on controller. Controller on machine must be simple to be robust and less expensive. Controller must be seamlessly joint with CAD/CAM terminal. All calculation must be done on CAD/CAM and controller should transfer necessary data (probing of surface) to CAD/CAM terminal for re-computing and after that receive back NC program. This is first important part as requirements for EMC2. Thank you Aram Aram, EMC IS capable of 5 axis dynamic compensation. EMC IS capable of probing the part and adjusting the program to the part on the machine table - in the 5 axis world - in the many axis world. EMC IS capable of processing the part program through the CAD/CAM system to utilize the tool geometry from the tool table. Five minutes ago I visited with a man here about this very subject. He said we could send a command to our Windows based CAD/CAM system, batch process and post process the file, return the gcode file to the EMC control. All this from the file load screen inside EMC. We will try to get this working this week. My experience with him is - if he says it is possible - he will do it. Having some fun now. thanks Stuart - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Zero gage length
Hi I am interesting in ZERO gage length capability of controller because length of tool is only on parameter of tool- length. Idea is create program on CAD/CAM and machinist will look for tool and whatever he finds tool he measured put into controller and controller recalculate actual tool path. So, tool length is only on parameter that describes tool, what about diameter, what about taper, what about form tool with special geometry that that we start use more and more and more, what about corner radius what is extremely important for surface machining, what about number of flute and others parameters? I thing that EMC2 controller should become extension on CAD/CAM terminal/(computer station) that generates NC code. Is it possible to configure EMC2 as a extension of CAD/CAM terminal/ Thank you Aram -- Message: 8 Date: Thu, 7 Feb 2008 21:39:49 -0700 (MST) From: [EMAIL PROTECTED] Subject: [Emc-users] Zero gage length To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Cc: Enhanced Machine Controller emc-users@lists.sourceforge.net Message-ID: [EMAIL PROTECTED] Content-Type: text/plain;charset=iso-8859-1 Hi I want to ask, can EMC2 work with program that created with ZERO gage length.

[Emc-users] DaDynamic compensation.
I think that EMC2 can become industry standard if it will oriented to the shop floor needs. I want to talk about of concept idea new requirements to EMC2 as I can see. My point of view as a employee of big machine shop. 1. EMC2 must be able to do 5 axis dynamic compensation. I think it is self explanatory. EMC2 should be able to use probe to heat the 3 points create plane square the machining axis accordingly and recomputed 5 axis path. Let me talk about. As right now many machine can do X Z and B axis dynamic compensation. Very view absolutely new machine can do 3 axis dynamics compensation. None of machine as I know can do 5axis dynamic compensation. How to do this? One way is to continue increase capability of controller on machine. Right now controller on machine can do B axis skew and move X and Z axis. What about move same direction? Add A axis skew and move XY and ZY axis compensation. That way will increase cost of controller, make controller more complicated and less reliable. I think it is wrong direction! Here is right direction as I can see. First, EMC2 is extension of CAD/CAM terminal. How it can be used in case of 5 axis dynamic compensation? CAD/CAM direct tool probe to the points on the part/fixture to heat or probe out. I recommend that after probe heat a part/fixture signal from probe must be sent to CAD/CAM terminal. CAD/CAM terminal will much faster recomputed new NC program and load again on controller. Controller on machine must be simple to be robust and less expensive. Controller must be seamlessly joint with CAD/CAM terminal. All calculation must be done on CAD/CAM and controller should transfer necessary data (probing of surface) to CAD/CAM terminal for re-computing and after that receive back NC program. This is first important part as requirements for EMC2. Thank you Aram Aram, Hi I am interesting in ZERO gage length capability of controller because length of tool is only on parameter of tool- length. Idea is create program on CAD/CAM and machinist will look for tool and whatever he finds ?tool he measured put into controller and controller recalculate actual tool path. EMC will do what you want and more than you asked. You can have a zero tool length in the post processor. You can have a zero pivot length in the post processor. EMC will calculate/compensate for the tool length and pivot length. EMC can also compensate for manufacturing/assembly errors for the rotary movement of the machine axes. You can compensate XYZ to move the machine around a perfect pivot point. So, tool length is only on parameter that describes tool, what about diameter, what about taper, what about form tool with special geometry that that we start use more and more and more, what about corner radius what is extremely important for surface machining, what about number of flute and others parameters? Sorry, diameter is not addressed yet. I have talked with some of the developers about 5 axis tool diameter compensation. I believe it should be as easy to implement as the 5 axis tool length/pivot length compensation. OK, maybe a little more complicated but it is very doable. I thing that EMC2 controller should become extension on CAD/CAM terminal/(computer station) that generates NC code. Is it possible to configure EMC2 as a extension of CAD/CAM terminal/ Somewhat, as I explained in the generic controller post, this is possible. A .apt file is the extension used by APTOS/APT360 to process and post file. With a script EMC will automatically process, post and load the gcode into the control when you pick the .apt file to load a program into EMC. Other CAD/CAM systems could do this just as easily if they would run in Linux. You would then be able to describe the cutter in the tool table file, have the CAD/CAM system process and post it. With the speed of the computers this could be done in real time allowing you to do all the things you asked about. This would not be the perfect fix. There isn't a perfect fix, but this would be closer. Thank you Aram thanks Stuart - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Touch up screen device -who is mfg.
Hi Stuart. I want to buy Keytec model KTMT-1921-USB what is 19021 inch. is this good model? Will it work with Lunix? Any final recomedation before i buy it? i assume that bigget screen will work with smaller monitor. Am i right on last one? Thank you Thank you Aram Aram, The problem with using a monitor larger than the touch screen is the Keytec configuration routine. It has you touch the lower left corner, then the center of the monitor, then the upper right corner. With the monitor bigger than the touch screen you will not be able to touch the corners. This will not allow the configuration of the touch screen. thanks Stuart - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Touch up screen device -who is mfg.
Hi Stuart, Can I use 17 inch touch screen with 15 inch monitor? Can touch screen be bigger or smaller than monitor and any limitation there? Thanks aram Aram, The touch screen I use with EMC2 on 6.06 LTS is the Magictouch overlay. This can be used with any monitor. The 1315 is the one I have. It will fit (barely) a 15 inch screen. It will work with any size monitor up to 15 inches. Keytec, the manufacturer, has an autoinstaller. This worked very well for the last install. You can download this from the Keytec website. I have purchased several of the overlays on EBAY. They have all worked. You shouldn't have any problems with them. I haven't used the USB connectors. I use the serial connectors. Be sure the serial connector is included in the sale. thanks Stuart - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Emc-users] Help with Machine Building
Hello I want to build a small cnc demo machine that design only to demonstrate how axis move and not to make steel chip maybe plastic or wood chip. I want to use 3/8 lead screw. In X travel 30 inch, Y travel 25 inch, Z travel 12inch. Here is place that makes screws http://www.hsi-inc.com/lead_screws_and_nuts.php Unfortunately they do not make trust bearing that should hold end of the lead screw. So I am looking to buy stage trust bearing that will hold end of lead screw and absorb axial load force from lead screw? Servo motor should not have any axial pressure from screw so all axial force should be absorbed by trust bearing that I need to find. So I need help in finding those trust bearing that should hold lead screw. I check http://www.mcmaster.com/ and many similar places but no luck. Because it is demo machine linear bearing will be from Home Depot. Thank you, Aram - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Touch up screen device -who is mfg.
Hi I found touch screen on fry's http://shop3.outpost.com/product/5215707;jsessionid=ztaoYpuY180IZdYaGds0aQ**.node1?site=sr:SEARCH:MAIN_RSLT_PG does it mean that any touch screen manitor will work with EMC2 or only special model? thank you aram I have worked with touch screens in linux at a previous job. Controllers that are Microtouch and ELO based are well supported. These have either a serial or USB interface. Here is how to set them up. http://tldp.org/HOWTO/XFree86-Touch-Screen-HOWTO.html#toc6 As for getting a hold of a touchscreen, I would just do the usual ebay/web search. You do not like ebay, so how about this: http://www.superwarehouse.com/17_LCD_Touch_Screen_Monitors/c3/2053 Basically search the web for Touch Screen LCD monitor You will have a hard time finding just the touchscreen glass/controller by itself. So count on getting a new monitor with it. You have to be careful though, here is a cheap mini lcd with touchscreen: http://www.chinavasion.com/product_info.php/pName/desktop-lcd-monitor-with-touch-panel-with-vga-8inch-screen/ It states that it comes with drivers but that is no guarantee it will work under linux unless you investigate it further. - Original Message - From: [EMAIL PROTECTED] To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Cc: Enhanced Machine Controller emc-users@lists.sourceforge.net Sent: Saturday, January 26, 2008 9:33 PM Subject: [Emc-users] Touch up screen device -who is mfg.
