[Emc-users] G540, trip pots and stepper motor temperatures.
I'm getting my little Unimat CNC lathe going, and am doing axis running tests; right now working on the Z axis (carriage movement) The X axis stepper is sitting idle, the Z axis stepper is running back and forth. It is really hot to the touch, and one can smell hot insulation. From what I calculated, this NEMA-11 stepper motor has a motor voltage of about 68 volts, running it on 48 volts. (the X axis stepper is slightly smaller) When it was just sitting, the motor was hot to the touch. From reading this list, one might think that running the motor might actually keep it cooler. Anybody know why one stepper motor would be overheating? (10mm/sec step rate, not overly fast) Yours truly, letting things cool off before trying anything else; John A.

Re: [Emc-users] Small Easy To Install Embedded PC Power Supply
Hi Bruce - (I really like Sherline lathes - and was looking at getting a Sherline like yours before this Unimat came along) My blog (cnc-for-model-engineers.blogspot.com) is meant to help those who, like myself, are computer-savvy, and are not career-machinists. I was at the Harrogate show (UK) a week or so ago, and, probably 90% of who I saw wandering around were older than I am. So, in order to keep the metal bashing side of model engineering alive, people a generation younger than I am need to get interested. I know one or two of the suppliers there understand this, and are working to modify their wares... Taking a little unimat/sherline lathe around, and actively showing it off, and answering questions can only help. I know Cecil on this list has a really good little one, and there are probably others...

Re: [Emc-users] Poor CV
Probably a dumb question, but, what acceleration values are you using on the LinuxCNC setup? My little mill was transformed when I added a 5i25, and really looked at what some of the values are. It now runs up to 10x faster than before. Two values were tweaked; acceleration, and max velocity. Now, I know there may be other issues, but the first half of your clip looked like my mill before, the second half after. I could be off in left field on this one, which would not be the first time!

[Emc-users] Cecil Thomas - CNC'd Watchmakers Lathe
Cecil Thomas mentioned in another thread that he'd cnc'd a watchmakers lathe. I'm looking for ideas here. A Unimat SL1000, MK1 landed on my desk last Saturday. It's mine if I want it. Have been thinking of taking some of my CNC parts kicking around home and using them, but I don't think using a 5i25 + 7i76 + Nema 34 steppers is great. So, with a little lathe like this, if I go with NEMA 17 3D Printer steppers (think Reprap or one of the Thingverse machines), what would be the best, least expensive way of driving these steppers from a LinuxCNC setup? Do the C10 boards, as shown in www.automationtechnologies.com's stepper motor kits work with LinuxCNC? I expect this little lathe to be a toy or demo lathe; take it along to shows, etc, and have it run making little brass swarf piles. I do have a computer put together with 5I25 and an Intel D525MW motherboard waiting to sit beside my larger CNC lathe build, so I could use that for computer horsepower. Thoughts?

Re: [Emc-users] Cecil Thomas - CNC'd Watchmakers Lathe
Hmm - lots of very good thoughts and suggestions so far, obviously lots of out of the box thinkers here as expected. I do have two colleagues who are unabashed hoarders of stuff, so maybe I'll ask them about stepper motors. Ralph: You could use a Gecko G510 for a tidy little package. You could use a NEMA17 to drive the spindle as well as X and Z, then you could have a C axis and amaze people with tricks like machining offset lobes on a cam, or use a flex-shaft Dremel-type tool for live tooling. If you mean the G540 - I use one on my Sieg KX1-NU mill, and it works really well with the Mesa 5i25. Hmmm - replace the motor with a stepper - there is the stepper head build going on in Model Engineers Workshop, so this is an interesting idea. The little Unimats are not very solid, IIRC (I had one as a teenager in the '70s), but this one is a shorter bed, so maybe might be stronger? (less flex in the bed rods, I'd assume) I can see this little weekend warrior project turning into something rather larger! ;-) JohnS. -- Minimize network downtime and maximize team effectiveness.

My story. Pre-coffee, so hope it makes sense. I had some conceptual difficulties with the 5i25, going from software stepper (driving a Gecko G540) to this drop in replacement. The main issues I had was in thinking about input output pins. Basically, I loaded the g540x2 image at startup. I had to stop thinking about pins at the DB25 connector, and concentrate on the functions - the output of the functions themselves actually drove the DB25 pins. The 5i25 can drive a G540 stepper controller, or it can drive one of the stepper/servo boards. (or, probably other things). The 5i25 does not need to be re-programmed to change what it is connected to, it is configured on startup with a do this parameter. Once I figured it out it makes sense, and I'm really happy with my configuration now. I purchased 2 5i25s, and one 7i76 (the stepper daughter card). One 5i25 is in place as a replacement for a dumb parallel port card. The other 5i25 and 7i76 is for a CNC lathe I'm putting together - I wanted spindle rotation reading for threading, and I believe that this combo will work well. Software stepper is a great way of getting a machine up and running, so no issues there. Adding the 5i25 allowed me to increase speeds while not getting following errors or RTAI errors, which did show up once in a while before. Hope this helps - down to get coffee. John A.

Jeremy; you did answer one question though and that is the 5i25 will do step gen I did put a 5i25 in a computer controlling a mill; the mill now *flies* if I want it. I cranked up the maximum velocities, and it can run 10x faster (rough guess) for hours without throwing up a real time error. Not that I normally make it fly as fast, but I figured that if it could do fast things, it could do slightly slower things, too.

My small lathe (Emco Compact-8) has grease fittings, and the instruction manual says where to grease and/or oil. My larger British lathe came pre-greased, in the same areas that the Compact-8 uses grease, so it seemed fairly natural. Have been (slowly) flushing the grease out of the system; it is well oiled now. Only one fitting can not be greased; I think I'll have to take the apron off and really see what's happening. (the fitting is right beside the threading lever, and it's either a tapped hole for a stop that someone put a fitting on by mistake/mischief, or it's blocked. Not a lot of threading done on the lathe) My oil gun is a jet lever grease gun, bottom cut off and plugged; so where the spring plunger is is blanked off. To use it I invert the gun, so grease goes into the lever mechanism and gets squirted in.

[Emc-users] 5i25 and pncconf and g540
Can anyone tell me why it is so difficult to configure a G540 to run with a 5i25? Chris Morley has done great work with pncconf. But, I could not see how to configure a g540 with a 5i25. So, I got the latest linuxcnc source, downloaded and compiled today, ran pncconf and still no luck. Now, I have, in the past, gone through the HAL manual to add/change things, but, come on, this is not something you expect normal, everyday people to do if you want to run a mill with touch probe and mpg, with, cross fingers, maybe spindle speed control. Maybe I was expecting too much. Like, something more like plug and play, not rocket science. This seriously is making me consider going to the dark side and running - shudder - windows (first time since 1986) and purchasing Mach3 for my CNC lathe. Certainly, the week it has taken me to get absolutely nowhere with my mill, has taught me a lesson here. The 5i25 is coming out of the mill computer, it seemed to run linuxcnc just fine, but I thought I'd have the computers for mill and lathe identical. Wrong. Ah well, back to software stepping for the mill, and maybe the lathe will not get CNC'd after all. Sigh. JohnS. -- Master SQL Server Development, Administration, T-SQL, SSAS, SSIS, SSRS and more.

Re: [Emc-users] OT - liquid pump for really cold temperature
Viesturs; We are in for another bout of cold weather, with night time lows of -30C. I have a block heater in my little Toyota Matrix, and when it's below about -20, I plug it in, and turn it on an hour or two before we try to start the car in the morning. It *does* make a difference. The car engine does turn over better than without it. Simple, reliable. Buildings here used to have (and, at work, still have) block heater plugs. But, now with fuel injection, the old if it does not start in three rrRRRrrr-rrrRRRrrr's when turning the ignition key go back to bed no longer is an issue; the car simply starts. But, the engine makes less noises if the block heater has been turned on for a while beforehand. John A.

Re: [Emc-users] OT - liquid pump for really cold temperature
Viesturs; Another really off-topic post. Years ago, my wife at the time and I purchased a new diesel VW Golf. It came with the standard one year, anywhere in the world we'll fix it warranty. 6 months later, we were living in the Netherlands, and this car made it over with us. One month after that, I got a recall letter in my forwarded-from-Canada postal mail. The recall notice (in Canadian Traditional Format - english one side, french the other) said that there was a recall on some power steering units, and to take the car to your nearest dealer. So, I did. The dealer around the corner in The Netherlands had never seen a recall notice with english on one side, french on the other. He had no knowledge of the recall ID, either. But, he said leave it with me, and I'll get back to you. We did, and he did. The problem was that the power steering unit leaked when cold. There were no parts available in Europe, as it only got that cold on this side of the atlantic issue. So, he returned the car, the french/english recall letter, a covering letter from the dealer written in dutch, plus an inspection report in German, indicating that the car had been inspected within the warranty period, and it was not an issue in it's current location, but if it ever was re-exported back to Canada, that the power steering unit would be replaced free of charge. So there! John A. Stewart Ottawa. -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

[Emc-users] converting TO a Mesa 5I25
Hi all; Received my 2x Mesa 5I25 plus 1 7i76 (the stepper interface) One of the 5I25s is going into a sw-stepper to Gecko G540 based box, on a mill with rotary table, touch probe and mpg. Other than starting from scratch with pncconf, is there an easy way to convert the ini files by hand to the 5I25? I do have this mill set up the way I want it to be. The ini files are hand-modified. In case you are wondering: Why go 5I25 for this mill? a) computers for mill and future cnc lathe are then identical, hw/sw wise; b) work through the 5I25 so that I know how it works under the hood before tackling the CNC lathe. I do have pncconf up and mainly running (thanks Chris Morley) but wonder if it might just be really easy to do the conversion by hand. Thanks for any advice you can give this newbie; John A.

Re: [Emc-users] What current ITX board?
Hi Sven; I'm not saying you are wrong; and I thank you for posting the results of your testing. And today I did. Running 2x2 GB RAM to maximize the I/O. Latency test, one glxgears and a Firefox to linuxcnc resulted in 15 849. Turned the graphics resolution down to 1024x768 and I was able to keep it a bit lower, But only a bit as I passed 14 000 for the same test. I still don't believe in you guys saying that a D525MW is able to stay below 10 000 in a latency test. I don't think you changed the graphics driver just by lowering the latency. I have not done much Linux stuff in years, but I'm wondering what X graphics driver you are using? Can you force the graphics driver into some VGA totally software render mode? Also remote into it, and run it as a headless station. I should do this and see how it performs. Maybe next time I have a few hours around the house (hah! not in the next few weeks…) I'll run that test. One thing though, I filled one of the boards with 8 GB RAM (2x4). That board is running 64 bit Ubuntu in the office and it happily reported 8 GB even though the hardware spec says max 4 GB. It seems that 4 GB is a soft limit. Running a 32 bit kernel? I don't think you'll be able to address over 4g via sw. Maybe they expect people to run windows, not Linux! Interesting that you can put the RAM in, as like you, I had assumed that it was not just a SW limit. Thanks; John A. Stewart. -- LogMeIn Rescue: Anywhere, Anytime Remote support for IT.

Re: [Emc-users] Curves in ZR plane.
Andy; You would have to raise an error in cases where the three points lie on a line. G16 appears to be available for setting this mode, and even makes sense as the zeroth member of the set. 3 vertices doth make a triangle; should two of those vertices be equal, one hath a degenerate triangle (i.e., a line), should all 3 vertices be equal, one hath a really degenerate triangle, called a point. My 3D rendering code uses Quaternion SLERP to go from one point to another. (Wikipedia is, of course helpful here) If you want to see the code, one can see it; http://freewrl.sf.net, or, sneaking around the back http://freewrl.cvs.sourceforge.net is the full code base. For Android devices, I'm adding a STL front end to it, and planning to add many more neat features, but I'm charging a minimal amount for it. (no app name here, but if you look for it on the google app store, my name is a clue) I mention this because, yes, getting a normal from 3 vertices can be slightly problematic, but that's a simple check. Also, SLERP code is available, written in C, as well as all kinds of functions, etc. I'm still learning GCode, so G16 is still a blur to me.

Re: [Emc-users] I crashed my machine, now I need a new drill chuck
Hi all; Just for the record, on my KX1-NU mill, I use ER-16 collets. I made the MT2 adapter, and got a smaller nut from Maritool. So far, despite having about 20 things I can stick in it's MT2 taper, I have not removed the ER-16 holder since it was installed. I DO LIKE the idea of the Tormach Tooling System, as using an equivalent described in Model Engineer back in the '50s for an older lathe I had worked wonders for repeatability.

Re: [Emc-users] I crashed my machine, now I need a new drill chuck
Jeremy; an endmill holder of course!!! thats what they are for. If you mean the ones with the screws on the side for weldon-shanked end mills, they have other issues. By definition, the holes in these holders are larger than the end mill shank. (otherwise you'd never get the end mill in) The screw acts as a pivot point. So, you essentially have an end mill flexing in the holder; leading to wear, and if the end mill is not inserted properly, it *will* walk out as far as the screw will allow, so if you do use these, of course you are going to pull the end mill out by hand as you tighten the screw. The wear will appear as oval on the end of the holder, but it'll be tapered. Think about it - you are shaking that end mill shaft a few thousand times per minute, and there IS play in there. Ok, ok. I gave away my clarkson auto lock chuck because screwed end end mills are not available, while plain shank end mills are a dime a dozen. (that's an expression, not a pricing structure!) For the last 2 decades I have only used top-quality ER collets. My ER-25 set are Regio-Fix (Swiss) with Schaubin (sp?) holder. My 16 and 40 sets were from Maritool - probably paid too much, but as they all just work, with no known issues, so I'm sold. Just make sure that they are clean (I use a bit of aluminum flashing rescued from some house-repair contractors to clean the grooves of the collets). Anyway, I'm no expert, but the above may be something to think about. Will *you* experience wear in these screwed-shank holders? I've absolutely no idea, just keep it in the back of your mind that this can and does happen. Back to your regularly scheduled programme… ;-) John Alexander Stewart. -- Everyone hates slow websites.

Re: [Emc-users] For anybody considering upgrading their motherboard in the next few months.
Kent; my brag ... I processed an AISC steel structure model that Bob Lipman in my group had developed for an international data exchange standardization effort-- I know Bob Lipman, back when I was doing lots with the Web3D Consortium. Very nice, quiet man, and I always found his company a pleasure. Putting my 3D software into the PDF reader was something that was requested, but there are just too many hours in the day. Getting it to work as a browser plugin, cross platform, was more than enough of a pain, especially when the browser wars were at their peak. brag off Bob made the VRML Plugin Detector, which was recognized as one of the standard VRML/X3D tests for HTML browsers with a VRML/X3D plugin. 3D on the web is an interesting subject; for a little while I was a representative of the Web3D Consortium for the HTML5 Working Group. It was certainly an interesting time, but not one that I'm eager to repeat. The open source VRML/X3D browser that I managed was the largest open source project, and the longest running open source project, managed by the Canadian Federal Government. Unfortunately, or maybe fortunately, getting traction internally for this set of projects was difficult, so, although the work and people interesting, I'm glad to not be involved in these groups officially any more. One of my colleagues (and, competitors) in the X3D environment is now technical director of Shapeways, so the world is indeed a small place. Although I was paid to write/manage this software by the Canadian Government, if I *did* have $0.50c for every download, my workshop would be a lot larger and more impressive than it is now! 8-) Another John Stewart. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Viesturs (and others) Now while I have not implemented the CAD profile in the FreeWRL rendering engine, you *may* want to have a look at it for your tablet-based 1495 parts CAD model. The CAD component is quite simple to implement, just never seemed to have the time and/or inclination. Other things, like machining, taking the dog for a walk, and especially being in contact with my wife seem to take priority (!!) , but feel free to bug me about it if it is of interest. Right now my focus for my FreeX3D Android app is to allow STL-model-interested people to modify the appearance of their STL model; cube mapping, spherical environment mapping, procedural texturing so that their models have a wow factor. The UI also needs work, but that is in progress. Once that is done, more work on actually manipulating models, much more than the current common vertex/degenerate triangle locating code that it currently does. John A.

Re: [Emc-users] For anybody considering upgrading their motherboard in the next few months.
Eric; I think your point about the desktop is well taken, and somewhat problematic for people that like to do things with computers. I think that mobile devices are very good for checking email, but that's as close to work as you can get. Disagree. Have an Android app. that displays VRML/X3D and STL files. For a while was an iPhone developer. Apple distributed my free desktop software until I stopped paying for the privilege of having them give it away. If it was iPhone, I could use the GPU to do 3D cylinder/triangle collisions for CAM work. Android does not (yet) support OpenCL, so my algorithms are sitting, waiting for my iPhone port. These algorithms run 10x faster on the GPU than the CPU on my desktop computer for large models. The programming paradigm shift will eventually hit all software, as desktop hardware is not being developed in any great sense any more. The future is in mobile hardware, even if tied to a desktop. I hope to eventually get my 0.99c app to do model slicing and CAM tool path generation, and reflective/refractive viewing of models. Do your publicity shots on the bus or train on the way to work. Do the tool path generation while walking down the street. (watch your feet though!) Sure, mobile devices are slower than desktops of the '90s, but, once you figure out how to program mobile devices, you fly. I'm not going to advertise nor push my Android app here, especially as some of the neat work is not yet released, but I would just say do not dismiss the technology behind mobile as it will *be* the desktop, and mobile, and everything fairly soon. Keep your eyes peeled on the mobile devices. Passively watch my app in the Google Play store, and see what it eventually does. (look for my name as author). Never say never.

Re: [Emc-users] Problems with smartProbe.ngc..
Jason, I'm not around my machine right now, and I could be totally off base: One of the probing routines, after it found the side, but before moving back, I had to give the probe a nudge into the object by about 0.02mm so that, on the return, the Gxx command would not start with the probe tripped error. Check to see what the command is that trips; it it is one that EXPECTS the probe to be tripped at start, ensure that the probe is tripped by pushing it into the work slightly. on my cnc4pc probe, I think that the slow approach to the work caused some vibrations that, when the probe was at the tripping point it would trip, but settle back once the find the surface command finished. The go back from surface, assuming it is tripped at the start command sometimes failed. Pushing it slightly in towards the work sorted that out. Make sense? John A.

Gene, Andy: Andy; I thought it was reliable, too…. (read on) I have 2 of them, running at 23000 ns for a BASE_PERIOD. I can run most of the day without encountering a realtime error. Good - I'll try your BASE_PERIOD - (read on) I assume you also have the option set in the kernel line of your grub.conf Thanks for the slap on the back of the head . Let me check that - I did but it might have been removed by some machine updates. Going to 23000 will make a noticeable difference in the machines top speed in that event. :-) That also assumes you have stepper voltages high enough to make decent torque at those speeds. 24 is often borderline IMO, my mill is running a 28 volt supply, my lathe a 38 volt under load.

Re: [Emc-users] Usefulness - was Re: OT: 3D Printer Mods?
Hi Joseph; John, I can tell you for sure that the parts end up being much stronger than you might at first guess from being printed hollow. That isn't to say that they are indestructable -- but I was skeptical at first, too. The application you mentioned is actually perfect for 3D printing -- the various one-off'ish bits and bobs that you would rather not spend much time tooling up to make. I absolutely agree with the whole issue of 3D printing, so my personal issues are more to deal with my specific application than with the process. Just an FYI; I make 1:16 and 1:8 scale steam locomotives; soft plumbers solder does not hold up well on most parts of the locomotive. I've had issues, and have seen some messes when people used soft solder for detail work. For sealing water containers (locomotive tenders, etc) soft solder is ok. These things have coal fires that glow orange when running, and the water in them is at about 170 degrees c. and do indeed get hot. Just fyi; right now my silver soldering of a copper boiler outside (hope to complete 2 this summer) is with Easy flo 45; it melts at 1125 degrees f; 605 degrees c. In shade, the copper sheet glows cherry red/orange, and brass will melt not much higher than that - I have melted brass components by accident before.

Yes, I could get something sintered @shapeways, but I can generally just fabricate the bits and silver solder them and turnaround is quicker than Shapeways. For my wife, 1:87 scale modelling is ideal for the home printed plastics, but the resolution is not there yet. I keep looking, and was really impressed with the b9 creator - learnt something today. I know that sometime sooner rather than later, the scale will tip, and 3D printers will become common place, like CNC machines are now becoming. So, if you hear me, or someone else say I have no use for a makerbot or rewrap or .. it's because, well, there's not a need. Sure, I can change hobbies and create a need for a makerbot rp machine, but my wife and I have a couple of hobbies that we enjoy, thank you!

Re: [Emc-users] Parallel Adapter
Jeshua; So how would that be specified? 0c090? The default is 0x378. It's in hexadecimal, so 0xc090 would be fine. (I'm no expert, but…) I just added another card to my system, and this card has 2 parallel ports on it. Each connector goes to a port; the issue is getting the correct address with the correct port; either trial and error, or just read the manual! (my second port came in at some high number like the 0xc090 or something like that; away far away from the 0x378 or 0x278 or whatever the usual is.

Re: [Emc-users] State of Wizards/Druids for simple machining.
Viesturs; (I can't agree or disagree with any of this thread, as I'm on an exploratory path, and I don't know what the eventual outcome will be) … but on the other hand, ngcgui probably should go mainstream as it is much better than hand-writing the code… This is what is bandied about in the Model Engineering forums - you can start CNC machining without needing CAD, CAM, or knowing what a G-code is - just use Mach3 Wizards, and all your worries will fade away. So, assuming the above statement is true, for a novice I can see the attraction of simple machining with your simple CNC mill, with the minimum of fuss. With the CAD and the CAM and the GCode coming later, if required. Much of my model building is simple machining operations, and I *do* find myself using my old mill rather than my new CNC one, because it's just faster to throw in a bit of material and machine it. eg: just finished making two forks - 10mm square steel, a 4mm slot from the end down the centre of one side for about 12mm, 10mm deep. No need for extreme accuracy, and only 2 required. I could machine it faster than I could type in the G-Code program, set my CNC machine up, etc, etc. So my old manual mill got the job. Now, if I had a quick way of clicking something, like the Mach3 Wizards are touted to provide, the CNC mill would have been powered up... These are all just thoughts and observations. --- John A.

[Emc-users] State of Wizards/Druids for simple machining.
Hi all; As we all know, Mach3 has a list of wizards to do simple things like pocketing, etc, without the need to do the g-code. Googling for wizards/druids or whatever, it seems like this idea never took off. Most references I see are from 2007-2009 timeframe. Yes, I do use the arc buddy, and so on, but it involves cutting and pasting and creating a g-code program; it's not standalone. Am I missing something obvious? Thanks; --- John A.

Re: [Emc-users] State of Wizards/Druids for simple machining.
Hi all; Thanks for the really interesting answers so far. I keep reading that LinuxCnc (emc2) is really hard to setup and use, and I do 99% of my machining with Mach3 wizards. Like many here I have been programming since Neil Armstrong walked on the moon, but that's not going to cut it for most newbies. So, I think that there's an opportunity missed for LinuxCNC here. Not that I have the answers (being a relative newbie here myself). The fact that my googling for emc2 and wizards did not find NGCGUI nor Anders scripts, and actually nothing newer than about 2007 leads me to believe that lots of people will assume that emc2 (linuxcnc) is not user friendly Just an observation, not a comment or anything.

Re: [Emc-users] State of Wizards/Druids for simple machining.
Viesturs; ... No offence to anyone, but LinuxCNC manuals perfectly explain, how to get started with this application, so I have a feeling that those who complain that LinuxCNC is not userfriendly, had not done the homework and had not tried to learn anything about the program (at least from manuals) and understand it. Agreed.

Re: [Emc-users] Axis Scale not quite right. HELPP!!
Joe; Three parts to this: Part 1: I initially had a problem with the scaling; eventually I figured that out. Q: Is it consistently off? What I did for my Sieg KX1-NU machine, is that I put a dial indicator on each axis; move the axis 10mm one way, and see if it works. Then move it back, then forward again. I found that my X axis was absolutely fine, my Y axis needed backlash compensation (a small amount). The fact that my machine was consistent with regards to what I commanded it to do, and what the dial indicator said, makes me feel confident with it. Part 2: I read somewhere that sherline mode helped solve some peoples' problems when cutting circles with some drivers; Not sure about the details, but it revolved somewhere around slow micro steps getting lost. Can someone else chime in here? Part 3: I initially set the latency too high on my computer; I'd get an error message on the axis display screen, bottom right corner; I'd expect that if your (great) computer was having issues, you'd see a message there, too. Part 4: Dumb question - is tool diameter compensation on or off? if on, is the diameter entered correctly?? Good luck, and please tell us what you find.

There are people who will make ink decals on clear decal paper (or, dry transfer lettering), so there are lots of ways still do this - I don't know the lead time or cost, though.

I added this by hand, to get the correct side (left, or right) so that the cuts/kerf were correct; 3) I should have modified the code so that, rather than cut-to-outline in x-y then drop, the final arc/line should have done the drop in the z direction. The parts produced have a little bit of an indentation at the point where the drop in z happened.

Kent, Rainer; WebGL does only about 5% of what the X3D spec does; mind you, for most users, that is the most important 5%. ;-) As someone who presented X3DOM to the HTML5 Technical Committee on behalf of Dr. Johannes Behr; I think that his approach is a good one. WebGL has its issues; and some big ones at that. But, if they can somehow give it longevity, cross platform compatibility, speed, and keep it focused on some core functionality, it'll do well. I would not keep models in a WebGL format; keep them in, say, STL, and that way you'll be able to re-render them in a few years, should you wish to.

This in addition to the VRML/x3d models we were already creating and which the community didn't like (we never overcame the problem of poor browser support of VRML after Silicon Graphics went belly up). With current browsers suporting WebGL it is quite easy to embedd a X3D model into a web site without any need for an extra plugin. I tried this myself some time ago and it worked very good. You can see the test file at [1] which i created in blender and exported as X3D. The documentation how to do it is from the official x3dom homepage at [2].

The community I served had seen the VRML effort peak and fade away long before and were very suspicious that X3D would go the same way. The specs kept getting thicker but the applications didn't grow. At the time we could only predict that things would get better. Considering that it's taken more than half a decade to get to where you can do what you did with X3D, they were right to be suspicious. Even now, X3D seems popular mostly in open-software ventures. This also helps explain my community's enthusiasm for 3D PDF. It was being touted by a commercial software giant they trusted to have staying power, Adobe Systems.
