Re: [Emc-users] Anyone coming to the CNC Workshop?
I plan on being there at least some of the time, and I think Tom Easterday (brought his Emco F1 last year) may also be coming. Thursday evening we're having an open house at Maker Works for CNC Workshop attendees. It's an 11,000 sq ft membership-based shop that will have a full wood shop, metal shop, electronics lab, fabric, plastic, laser, etc. Please stop by! Still setting up machines, several weeks from opening, but you can get the idea. www.maker-works.com We'll have details/maps at the workshop.

[Emc-users] PCB engraver, spindle solenoid
I'm fixing up an IBC BoardMaker , a 22 x 22 PCB engraver. So far I've replaced the Y axis with a McMaster-Carr 5/8 ball screw nut, which had been a proprietary-threaded rod with self-adjusting anti-backlash (plastic) nut that self-destructed, and replaced the stepper drivers with Gecko G251's. The machine uses a solenoid to move the spindle down until a wear-button hits the PCB, thus establishing the cutter height. Spring return. My question is about the solenoid drive. There are two identical circuits--both are logic-level in (from a db-25 parallel port) driving a relay that supplies +45V to the solenoid (i.e., they are in parallel), though one has a 5W 40 ohm resistor in series. (The solenoid is not identified, but has 70 ohm resistance.) This sounds to me like a way of driving the solenoid hard to move the spindle down, then holding it with reduced current. This is often done with a (big) cap across the current-limiting resistor. The solenoid doesn't move all the way down with just the hold current. I don't have the original control software, so don't know what the original software control signals look like. (IBC seems long gone, but may have had connections in the past with LPKF.) Does anyone have specific knowledge about what they intended as drive signals? I was tempted to replace the two circuits with just one, with an adjustable one-shot to drive the solenoid full, then a gated PWM to provide the holding current. (And replace those relays with a MOSFET.) But then I wondered if drilling or milling required a different set of timing than straight engraving? (In particular, I was imagining breaking a lot of 0.020 drill bits by driving full speed into the board.) Any ideas?

Re: [Emc-users] PCB engraver, spindle solenoid
Here's a picture of the front: http://www.redcedar.com/misc/IBC_BM.jpg The brass cylindrical object is the solenoid; it pushes down right where that green button is. To the right is the spindle motor. Just to the right of the cutter is the foot with a wear button on the bottom; this depth is adjusted via the knurled nut. The cutter is secured in the collet with a set screw (1/8 dia cutters). The spindle motor, foot, and cutter all move up and down on two 1/2 or so steel rods with linear bearings. In this photo, the top surface of the machine has been removed, so you can see the 5/8 ball screw below. --dg At 12:23 PM -0500 9/21/10, James Louis wrote: Dale, Do you have any pictures of the solenoid available?

Re: [Emc-users] PCB engraver, spindle solenoid
My inclination is to try to get this working without replacing the z axis. I like the depth adjustment, since it eliminates a major headache with engraving PCBs, and the current (as it were) arrangement (two distinct drive levels) was functional at some point. I've started looking into what options I would have to process G-code Z moves into various PWM or multiple signals--delving into the integrator's manual again. Many thanks for the ideas and cautions. --Dale At 6:27 PM +0100 9/21/10, Andy Pugh wrote: On 21 September 2010 16:58, Dale Grover dgro...@redcedar.com wrote: Does anyone have specific knowledge about what they intended as drive signals?

In theory you could then connect the PWM to the Z-position-cmd in HAL. G0 Z1 would be full-power into the solenoid, G0 Z0.5 half-power, and G1 Z0.5 F20 (or similar) would be a slowly ramping PWM suitable for gently pushing a drill bit. Setting Z-axis max velocity would determine how long a G0Z0 took to complete, you could then follow each with a G0Z0.5 to apply the holding current. -- atp -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

[Emc-users] Update on EMC at NAMES 2010
A brief update. * Seminars Matt Shaver and I will be doing two seminars about EMC, one per day, at the NAMES Expo. April 24-25. http://www.modelengineeringsoc.com/expo.htm Getting Started with EMC: free and open source CNC control software. Beginning with a brief overview of the components of a typical hobbyist/small business CNC machine, the seminar will focus on using the free and open source EMC software for CNC control. Topics will include where to get EMC, computer requirements, EMC capabilities, using EMC standalone for learning G-code, configuration, and operation. (This is obviously just going to be an overview!) Saturday's is at noon in room A, and Sunday's is at 10 AM in room B. I think Matt is doing Saturday, and I'm doing Sunday. * LiveCDs Marty Swartz is again duplicating EMC LiveCD's; we'll have 200 to hand out for free (probably half at the seminars and half at the table). We'll also have a handout about EMC like last year. * The Booth This year the NAMES folks decided we could be an exhibitor. (Last year we were a vender.) The good news is that this is free; the bad news is that, from what I now understand, we will have very limited space and be in an arbitrary location (first come, first serve). I unfortunately did not realize this when the option was presented. It sounds like no space for our EMC banner (sorry, Chips), and very little room for anything but a demo mill and example controller box and PC. Going back to being a vender may be a good route for the future--this kind of presence doesn't seem to fit into a good category at NAMES. In the end, though, I think we'll be able to talk to a bunch of folks and introduce them to EMC, which is the point. I'm looking for volunteers to be at the table for brief shifts Saturday and Sunday--especially during the seminars, if possible. Please email me if you can do that.

[Emc-users] CNC Workshop, EMC fest details
Just talked with George Bulliss about the CNC Workshop* and I have some more details on the EMC Fest facilities. It sounds like the CNC Workshop will be in a fairly empty building that has 4 classrooms and some large open areas. (For some reason I think this may be a newer building.) He has set aside one of the classrooms for the EMC Fest. I understand it to be near the entrance, with additional space right outside the classroom if needed. Pico Systems and PMDX will be right outside, and Smithy not far. We will have access pretty much as late as we want. A person will be deputized to make sure the door gets locked when the last person leaves; George will also give the campus security a list of EMC folks who will be cleared to be there late. The building will have wireless internet (open), and the room will also have ethernet (we might need to bring a switch). It sounds like the IT folks are being very reasonable to work with. If we want/need something more (within reason), we can let George know. They'll supply tables and chairs. There are 7 heavy duty workbenches in the building, and one could be commandeered for EMC to use for a heavy desk top mill if desired. It sounds like power will not be a problem (for 110V). If we need 220V in the room, let me or George know. Further note--one of the other classrooms in the building is outfitted with PCs, and it sounded like it would be possible to boot these off of CDs (e.g., EMC Live CD). If this is useful for a class or something directly EMC-related, you can get in touch with George directly, or I can batch the requests for the next time we talk. From what I'm hearing, George is really willing to do what he can for the EMC Fest, and the college is being quite supportive. It sounds like it will be a nice setup for the Fest. --Dale *CNC Workshop, June 22-25, 2010, Washtenaw Community College, Ann Arbor, Michigan. http://bbs.homeshopmachinist.net/forumdisplay.php?f=10 -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Re: [Emc-users] Portable EMC?
If the BeagleBoard port works out, we could then look at other, cheaper, ARM9 boards. The BeagleBoard has all kinds of stuff we don't need (e.g., video, including 2 or 3D acceleration), and leaves out ethernet, plus may be subsidized (and might have some availability issues). If we can get to a more generic ARM9 board, I think we'll have a really excellent solution going forward for EMC, with even more of the benefits Jon lists below. (There are even some fairly cheap--$100/qty 10--boards with ARM9 and a small FPGA, along with ethernet, memory card, etc.) However, the BeagleBoard is popular, has lots of on-board resources, and so may be just the right environment in which to get the ARM9 project going. I look forward to hearing more progress on this front. It's not going to be the only solution for everyone, but for a lot of us, it will be very useful and very powerful, and will get us past the parallel port issue definitively.

It's definitely smaller. It's somewhat less expensive (though I'm not sure how far below $220 you're going to get, once you add a power supply, I/O conditioning, etc), it takes somewhat less power (3W vs. 26W). For the small differences in cost, size, and power, you end up with a full PC with gigabit network, 1.6GHz dual-core CPU, reasonable 3D graphics, excellent latency numbers (maybe 8000 or so IIRC), and a PCI slot. Of course there's always a bit of pride to be taken in doing more with less, I'm not sure there's really a great payoff here. Does this have a parallel port that does EPP? The Beagle is actually quit cute. You can run it quite well off an 8 GB SD card, no hard drive at all, and a USB-Ethernet dongle. So, that is about $208. I just found out how to use one of the $9.95 Chinese USB-net dongles, so that drops the price down to $175 plus some shipping. It runs off a single 5 V supply, a wall-wart is fine at these power levels. It would also run quite well from 12 V with a little regulator chip. You'd need some surge protection from the spiky car electrical system, though. I have a board that converts the Beagle's expansion port to 5 V levels and EPP parallel port pinout. (That will runs any standard parallel port function as well.) This whole new direction was started as insurance against loss of the old parallel port and possibly destruction of real time latency with newer incarnations of the Intel core 9000 hyper-megaplex CPUs in the pipeline. It would also allow people who INSIST on using old laptops to get their way. They could run the GUI on the laptop, and link to the beagle via Ethernet. The Beagle would be inside the CNC control box.

[Emc-users] EStop and iocontrol.user-enable-out
I have found a work-around, but wondering if anyone can point me to a better solution. I'm building a second CNC machine (another EMCO F1 with steppers), using the same type of Sound Logic breakout board I used for my first machine. However, I didn't use the charge-pump circuit on that first machine, and this time I did. The symptoms are that EMC, using a stepconf-generated configuration, won't bring iocontrol.user-enable-out high if EMC is started when the controller is on and the controller estop is inactive. I finally found this work-around (http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-04-22.txt at 20:15:13), which is to activate the estop on the controller, then click on estop in EMC, then release the controller estop. This somehow resets EMC's internal state. It works very reliably. One thing I did was to run stepconf with two different configurations--one with an external (that is, controller) estop, and one without. The one without an external estop runs fine--generates the charge pump signal and so on when the EMC estop is toggled, and so on. The only differences are in the nameOfMill.hal file (all the other files look the same): With estop: net estop-ext = parport.0.pin-10-in-not ... net estop-out = iocontrol.0.user-enable-out net estop-ext = iocontrol.0.emc-enable-in without (external) estop: net estop-out = iocontrol.0.user-enable-out net estop-out = iocontrol.0.emc-enable-in So this puzzles me--why does the second one work? user-enable-out is acting fine there, but not in the first case. I put up two halmeters, one on user-enable-out and one on emc-enable-in, and could watch the two cases. Using (iocontrol.0.emc-enable-in, iocontrol.0.user-enable-out) as a shorthand, this is what happens for the external estop case: Start up EMC, controller is already on, controller estop is inactive: (1,0) Activate estop on controller: (0, 0) Click on EMC estop: (0, 1) (note--user-enable-out is finally on, the charge pump is now active) Take controller estop inactive: (1, 1) and the machine is usable. I went back and checked--my older EMC (2.2.8) exhibits the same behavior, but it was never a problem because I don't use a charge pump. I tried to find out more about what might be causing EMC to output iocontrol.user-enable-out low, but couldn't find anything in the docs. So, one option is to live with the work-around. Another is to not use the charge-pump. But is there something else I can try? Am I even looking at this the right way? Thanks. --Dale -- Come build with us!

[Emc-users] more on the NAMES show
Adding to the other reports from NAMES... We had a lot of folks come by the booth on Saturday--probably handed out 200+ flyers and 70+ CDs. Sunday the attendance was perhaps 1/3 of Saturday. In the end we handed out a total of more than 100 CDs and 300-400 flyers. The folks who actually stopped in the booth ranged from active EMC users to folks just interested in learning about CNC. There were a fair number who mentioned the BDI CD, and a few that had not had great experiences installing EMC in the past (probably Linux installation issues). Heard many folks talk about the machines they had in their basement, or the parts they had been collecting, but they just had not pushed through to finish it up. My impression is that a lot of the people we handed CDs to will actually try it out. Most were very appreciative. We really didn't press CDs into people's hands. The booth looked quite nice (in my opinion)--the photos on the boards are 24 x 36 and are really high quality with informative descriptions. The banner was visible from across the hall. We ran the video of the 5-axis milling machine from Belgium (http://www.youtube.com/watch?v=DjPCEpZybXsfeature=related), and folks who caught on what was happening really enjoyed it. (Their machine was also on one of the photo boards.) Some suggestions: --Don't have tool changes in the demo G-code; interrupts talking with people when there's a tool change (or the machine stops). Or, have a couple of demos (one that is cool, runs largely unattended, and another that has tool changes and the like when you have someone ready for more details) --Find out what the attendance is like, don't assume a uniform distribution of visitors per hour --Get envelopes for the CDs (I dropped that ball) --Have a second machine to show exactly what Live CD will present to the new user so they can be walked through running a simulated machine (this was very useful) --Set up a PMDX-112 Parallel port simulator to show more concretely how one configures EMC for parallel port operation --Clear covers on the motor controller box were a hit--folks could see the various parts, but the plastic kept fingers out --Have a cooler demo piece of G-code (like a 3-d Chips), ideally with 4 or 5 axes. Chris Radek and John Kasunich came to the show on Sunday (and were a great help in tear-down--thanks!).Matt Shaver also drove up, and answered a lot of questions from visitors. Steve Stallings lent us a PMDX-112, the idea being that it would be useful to show how one went about configuring EMC for parallel port operation. It was hooked up and I showed the board to people, but didn't use it interactively--thinking about it now, it could have been more useful than my handwaving, though we really didn't a lot of questions about the interfacing issues. The biggest questions surrounded how one generated G-code and how EMC fit into the tool chain. Next year the show moves back to the Detroit area into a somewhat smaller venue. If we want to do a booth next year, we could coordinate it so that PMDX, Pico Systems, and EMC were all together. With more time, we could explore options such as negotiating a more appropriate booth fee, setting up an EMC seminar, CNC demo area, and so on. --Dale -- Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.

[Emc-users] NAMES, this weekend (4/18-19, 2009)
This is a reminder that the North American Model Engineering Society Expo (NAMES) is this upcoming weekend (4/18-19, 2009) in Toledo, Ohio. This is a fun show--many model engineers with some very impressive model engines and devices of all kinds. Also new and used tooling, machine tools (manual and CNC), related books, and materials. And free seminars (no CNC seminars this year?). http://www.modelengineeringsoc.com/expo.htm Some EMC supporters will have a booth (B-15, in the back) where we'll be handing out 200 Live-CDs with EMC2, demonstrating EMC2 on a mill, handing out flyers, and in general making folks aware of this excellent software. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2AtNAMES Jon Elson and Steve Stallings will have booths nearby. If you're coming to the show, we're still looking for volunteers to be at the booth. An hour, even half an hour would be helpful and probably even fun. Send me an email. But, it looks like we'll have a cellular internet connection there, so another way to help would be to monitor the EMC IRC channel during Saturday and Sunday (9-6 and 9-4)--if there are questions people have that folks in the booth can't answer, we may try to use IRC for quick answers.

Here's a link to make sure you grab the right ISO: http://www.linuxcnc.org/hardy/ubuntu-8.04-desktop-emc2-aj07-i386.iso The 2.3.0 version of emc2 is still in beta state, and won't be out until 15th april (if no issues appear). After that I will probably take a stab at building a new LiveCD with 2.3 on it. As for the artwork, not sure if this is what Greg has seen, but I did these a while ago: http://dsplabs.cs.upt.ro/~juve/emc/cd-cover/ Regards, Alex We have an EMC user with access to a bulk CD duplicator, so it sounds like we won't need an army of CD burners. I'll make sure we have the latest version. The artwork looks great. Not sure if we can do color or not, but will check. --Dale -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

Re: [Emc-users] EMC at NAMES, Apr 18-19
Would please someone tell me, being 1 miles away, what NAMES is and what it means, especially for EMC? Google gives me 9 million possibilites... Thanks Peter Blodow The North American Model Engineering Society Expo is a big US exposition for model engineering, a combination of exhibitions of models and booths by venders. You'll see Sherline, Village Press (publisher of Home Shop Machinist, Digital Machinist, etc.), and others aimed at hobby-level machinists, lots of used equipment dealers, and many exhibits of model steam engines, clocks, locomotives, etc. http://www.modelengineeringsoc.com/ There are also some talks scheduled during the day, and a theory of steam class that happens before the show. It's a great show, and I rarely miss it. There's a growing presence of CNC at the show--from components to complete systems, people demonstrating their converted or homemade systems, and talks on CNC. Some aspect of EMC has been present for years at many booths, exhibits, and talks--the booth idea is to have it be the focus of attention. --Dale -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

[Emc-users] EMC at NAMES, Apr 18-19
Booth 15 at NAMES will be ours for demonstrating/promoting/distributing EMC. This is in the back, with Jon Elson and Steve Stallings in nearby booths to the sides. For better or worse, the person I spoke to at NAMES felt vender status was appropriate (due to distribution of software, even if given out free); it sounds like something to work on changing for next year (Ron Ginger's connections would be valuable). For this year, consider it my donation to one of the coolest examples of open source out there (as a recent post put it). Please let me know if you would like to take a shift or two in the booth; create a handout, banner, or sign; demo a system with EMC; or have other thoughts about how to promote EMC. Of course, many other exhibitors and venders will be running EMC systems elsewhere. This is a chance to place the emphasis on EMC itself. Right now there will be at least an Emco F1 mill, and hopefully at least one other PC running Axis for off-line demos. Steve Stallings will loan one or two PMDX-112 boards for illustrating configuration. There will be room for more machines, and more knowledgeable people (in both senses). It seems like distributing actual Live CDs would be a Good Thing--any idea how many we could give away? Would burn-on-demand meet the demand? Would any purpose be served making fancy CDs with printing? Seems like folks would be fine with a CD with no printing (just envelope printed or stamped). NAMES is April 18-19, Toledo, OH. --Dale Would anyone have an objection to there being a table at NAMES to demo/publicize EMC?

Re: [Emc-users] EMC at NAMES, Apr 18-19
Good point. It sounds like the CDs should be behind the counter,
handed out to folks who seem genuinely engaged.
--Dale
Dale -
There is one downside to having a stack of CDs ready to go, and that is
the grab anything free mentality. I've never been to a NAMES show, but at
other professional or hobby exhibitions, people will line up for anything of
perceived value. (Screwdrivers, for example.) =WE= all know that there's
intrinsic value on that CD, regardless of whether the label is fancy,
simple, or merely scrawled with a Sharpie. :)
If you want some help with duplicating, please contact me off list. I have a
scary-fast CD duplicator. Marty [dot] Swartz at gmail {dot} com ..

NAMES is April 18-19, Toledo, OH. --Dale I am happy to see EMC will be represented, but it seems very unfair you should pay as an exhibitor. I have exhibited my CNC stuff, and given a seminar there for many years. I was asked by one of the committee guys to do everything I could to encourage more CNC demos. I put notes here and on other lists to do that. It has always been clear that Vendors that sell products should pay for tables, this is appropriate and necessary for NAMES to operate. But guys that demo their hobby stuff are exhibitors. They do have to pay the $10 to get in as does everyone, but they are not vendors. I have written to my contact and suggested this was not the way to build CNC demo interest. I will see what the response is. NAMES is run by a committee, and that has all the usual implications of a committee. Im sure many recall a few years ago when the committee was most uncooperative to our CNC demos. I have been assured that they all now realize that was a big mistake and they really want to encourage more CNC demos. In the end, NAMES is a great show, I would never miss it. I enjoy showing off my work and seeing what everyone else is doing. Ill be there, with a new router Im building (if I get it done :-) and hope to see lots of other CNC stuff. And we can debate the merits of our favorite software all weekend! ron ginger I have really enjoyed the CNC talks and demos that Ron and others have given at NAMES. They add tremendously to the show. (I always take notes at Ron's talks.) And anything NAMES can do to increase the CNC content would make me even happier. Please bear in mind that when booking this booth, I didn't press the issue about vender/exhibitor--at this point it matters more to me that EMC has a nice space and location, both true of this booth, I believe. I'm not offended, and could see the point of view that EMC does seem like a product, even if nothing is being sold. And I do see the booth as more than a demo--I think it really does want to be venderish in appearance and purpose. (One of many bad ideas I've had already--a sign with SHOW SPECIAL--70% OFF!! for the booth.) But I do think that, if in the future there is sufficient interest to have another EMC-specific booth/table/area, it is worth going to the NAMES committee much earlier in the year and exploring other arrangements, because EMC is a special kind of product (plus community). This kind of exhibit should (I hope!) add to the show, isn't making anyone any money, and builds the kind of community that NAMES benefits from. Definitely worth giving space to, gratis. Let's see what we can actually make happen this year. Looking forward to the show! --Dale -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
