Re: [Emc-users] Monitor cable lengths
When the analog signal degrades it still maintains a high level of information compared to a degrading digital signal. Compare that with a lithium Ion Battery driven tool and an older NiCad driven tool. The Nicad performance degrades slowly and in case of a drill you might manage to squeeze one or two of those last holes out of the tool. The digitally controlled Li battery will stop form one moment to the other. So, analog becomes gradually more 'fuzzy' and digital either works, or not in a rather catastrophic way. Having that said, the focus is clearly on signal quality. You can either switch to fiberglass transmission with encoders and decoders on either end, or better cables (makes a HUGE HUGE difference!), signal amplifiers, broad band cables with en and de coders. You can reach FAR but the distance comes with a price. 10-20 ft should be doable with cables made for the signals intended. And as expected... those will not come from China and cost money.

We replaced a crt in one lathe with a lcd, it shows some strange sync issues the crt never had. And that's only lowres 15 vga. So it would be nice to know what to expect with a higher resolution signal. Also interesting how some sites also recommend vga over dvi-d/i for longer cable runs. My expectation was a digital signal can be run longer than an analog one.

Re: [Emc-users] Brass fittings EMC
And regardless of your arguments, the one factor which distorts everything the most is the government involvement. The Chinese Gov is subsidizing the manufacturing industry so heavily that indeed it is cheaper to buy a bottle of water filled in China and then shipped around the world, than opening your tap. We have to let that happen as our government has sold us out to China so they could promise and deliver us a lifestyle in luxury... that was till the Chinese credit card debt became to big. Till the national debt is back in our control, all discussions about manufacturing technology and quality are completely and utterly secondary as the politics dictate the flow of things and not the economics of reasoning, quality, and how things should be done correctly in the first place. Every time I go to Home depot and have to buy one of their absolutely sub par fasteners I feel anger. Anger about the fact that I WILL have to replace that piece of junk, that I am lucky when I do not turn the head of that screw while tightening it. And so on and so on. The amount of lifetime wasted because of inferior products over the past 5 years is making me even angrier. So... please... it really does NOT matter how think your wall is in a fitting, what happens with the shavings, which alloy it is. The reason for all of this is on a different level. Controlled by people who like it just the way it is as we have to buy and buy and buy and buy again. Last week I went to Sears and bought a 1.4 inch tap and a cool ratchet wrench to tap a hole in a difficult to access location. I am not new to tapping holes I tapped three, then the wrench broke, and then after one more hole the tap... Wrench made in Taiwan 'according to the specs' of some importer. And the tap was made in China. Taiwan stuff is usually alright once one pays for good stuff. But NOTHING, not a SINGLE EFFING ITEM I bought with the label 'made in China' has held up even remotely to it's promise. Regardless if it's a friggin drill bit, or a cast piece of steel. ALL total garbage. The damage across the US caused by those inferior products, compounded by the amount of labor to fix those problems MUST outweigh the 'savings'. We have a local hardware store which has stock from the 40-60's as the previous generations must have had some luck buying up stock in the right moment. The quality of those parts is shocking compared to current stuff. Pipe fittings held 100 years, and now we have to exchange everything every 2-5 years because of 'shareholder value'... Haha,... we must be completely retarded as we are complaining and complaining and complaining. I personally think that it's actually time to stop buying that crap. It is time NOT to shop at Home Depot, or Lowes, or similar Asian hardware markets. I am having WAY LESS HASSLE since I buy US and European stuff at McMasters. Twice as expensive, but hey, it holds up till I DO something stupid with it. HAPPY NEW YEAR EVERYBODY!

If it's a DC servo then you can simply change the polarity while also swapping the pinout in the encoder accordingly.

Re: [Emc-users] 4th axis ideas... any suggestions?
Gears have backlash period. And if they don;t have backlash out of the box... they increasingly will have it. There's a method of countering that, but it increases wear as it uses tension. I rely on my steel loaded timing belts instead. I use the type made for the car industry. Incredibly strong PU with little steel cables in them. Even exceeding the suggested load max by a factor ten to achieve a guitar string like tension has not resulted in any failures yet. I cannot measure any flex at 160lbs of tension and the speed they can achieve is incredible. Less than 3 bucks per foot is also cheap. Many belts run in Diesel engines as valve timing belts for more than 50,000 miles before they are changed just for good measure. That's a lot of rpm's... and heat...

Re: [Emc-users] 7i43 and actual stepper and limit switch wiring questions.
The false trips are nearly always due to NOT using screened cables (including limits) and poor grounding and wiring techniques. And one MUST use a capacitor at the BOB to eliminate noise created by the steppers lines. a couple of yF and a fast cap like a ceramic one does the job to flatten those spikes out nicely. I actually changed my entire design and bolted the gecko's to the frame where the steppers are located and transport step/dir and power there rather than running the driving lines all over the place. I use differential encoders/decoders for the dir and step signals and feel that the steppers are more crisp compared to the ones driven through a few feet of cable. It also reduced the cost of cooling for the gecko's to -zero-. Rainer -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] Running the encoders directly to EMC
Skewered brushes make no sense at all. I agree. Skewered armature prevents a rapid fall off of the magnetic field and thus yields less 'chatter' if you wish to name it like that. If you would turn the motor manually over then a 'regular' dc motor would go 'pop pop pop' over the field boundaries as you manually break the hold, and a skewered design is way less noticeable. Insert your own 'swosh swosh or whop whop' haha. You get the point... And... keling is recommending the US encoders. And do not be afraid to plop any encoder onto any motor with the right shaft. Encoders have nothing to do with the motor characteristics. There is no adjustment of an encoder to a motor except for the rear shaft diameter and the max rpm so the poor thing doesn't fly apart. Regular encoders are a bad match for 320,000RPM air drills for example haha. That would be the fastest encoder in the world. parts will literally break through the barrier of sound... The encoder is a foreign object to the motor. The encoder is the right hand of the controlling drive and thus all encoder parameters have to be balanced according to resolution and drive it is connected to. I have no problem whatsoever viewing their website with Firefox, or Safari, or Opera, or IE check your setup Best of luck! Rainer PS:Be sure you have the right inertia match between servo and load. Or the tuning can become a nightmare. Which it is in any case, more or less, depending on the drive... Oh... and make sure that encoder and drive use differential signals. Cheap options are without the differential encoders and decoders It is mandatory in our environment to use differential signals. If not, just use steppers and forget about the servo as you loose all the precision benefits of the encoder while corrupting the signal with a bad choice of transmission. -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

(Q: What *are* EMC2's in-position tolerance settings, and how are they adjusted if not in the .ini file?) It is not in the .ini file because there is no in position tolerance. There is a following error tolerance, but that causes a program abort. EMC does not wait for an axis to be in position before continuing. But in the case of allowable following error, if the machine is moving with sufficient velocity, the allowable following error should ramp up from the low end MIN_FERROR= (Integrator manual shows as .010 default) to as high as FERROR= (Integrator manual shows as 1.0 default) (See Integrator Manual, Chapter 7.2.9, page 34) It DOES have asliding scale for following error. Could something like this be happening (normally) with the in-position tolerance values? If the machine has ramped up to max speed, and the next line does not slow things down (even if direction changes), then maybe in-position is reached as much as an inch early and the next motion (quite properly) begins? EMC2 computes how far before the end of a move it needs to decelerate based on velocity and the max_acceleration parameter for that axis in the .ini file. As soon as the currently moving axis begins its deceleration, the next axis to move will begin to accelerate when in G64 mode. In G61, that is defeated, and the move must be completed before the next move starts.

To drive it I will direct drive it with a servo and a backlash free cycloidal gearbox which I found on that show in New York for an affordable price. The ratio is 1:30 and the experiment will be done this summer. If it works, it will be a great alternative to a ball screw with all it's hidden issues. Right now I have very little to 0.125 backlash on the X axis. Which makes a very messed up and dangerous operation. I can only cut conventional in one direction or it will eat my breakfast, bit, and material. Time to toss it or overhaul the screw section...

One way to get good results with belts is to strobe them at full speed and watch the first tooth engaged by the pulley. If the tooth is trying to climb out, it's too slack. That fault often shows after a time as a line of wear on the pulley teeth near the crest, but it's a bit late then. Great hint! Thanks!

Re: [Emc-users] Mill-Drill needs steppers and servos?
I'm a chemical engineer and dissolve all my problems! Besides that we designed a timing belt driven CNC machine and operate it happily. We use a belt on each side of the long axis and that is about 27 ft. belt length. The steel loaded urethane belts are tensioned and sound like a base string. It's used for wood working and is accurate to .005 according to our mitutoyu caliper. I am suer that there is flew during the cut, but it's still elastic and when all parts finally stop it's back to dead on. parts cut to fit into each other (concave/convex) are fitting perfectly. So the different cutting passes are not yielding different tolerances. If, then they are below our capability to measure them. The machines run now for 2 years under Mach3 without a belt related failure. Which cannot be said regarding the operator failures. All I can say those machines ARE rigid hahaha. Breaking a 3/4 inch carbide bit in plywood and surviving it requires strength... The machines Gantry is made out of 4x6 square steel tubing and the frame out of 4x4 square steel tubing. We use stepper. 1800Ounce/Inch. We don't know about a single step we missed ;))). Belts are fun, cheap, and precise for tasks with a certain accuracy requirement. Any case a flex of .02 would be unacceptable for us. We do not see that kind of flex. It's really around 0.005 . The belts are european steel cable loaded AT5 belts 3/4 wide and driven on AL pulley's.

A clear live plot (ctrl-K) does not help but after shutting down EMC and restarting again the behaviour is as expected. With real slow I mean that it takes 1 - 2 seconds before EMC responds on keypresses to move an axis. In a normal situation the response is instantaneous and a short push on the page up key moves the Z-axis a bit (1 mm or so) but after running a large program a short press on page up results in a Z-axis move of 50 - 100mm.

Re: [Emc-users] Rotary Axis Designs
Haha.. The Belt Stiffness fools many. It's a PU timing belt which is steel loaded. I tensioned it to 160lbs and the think sounds like a guitar string. There is NO flex whatsoever. If there would be... most cars would sink their valves into the cylinders more often than not. The ratio is 1:3 and the stepper has 10 steps micro stepping. So I get 2000 steps per revolution times three. So I get 360/6000 degree resolution which I could reproduce. If you would use a servo then you can easily tripple that resolution with the right encoder. I chose a stepper there because I wanted the high holding torque for unbalanced work. Did I mention that it is FAST. I also hae a sherline table on my Taig mill. And that's where it belongs. I mill pen's with it and for that it's nice and very precise. However, it does wear as all the stuff does which is not designed for CNC kinda moves (which means a LOT of moves). And for the price of it I milled my monster 4th. The timkin bearings are sitting in those 3 Inch AL blocks 8))). Derived from the shaft all measurements became slightly beefy lol. I also milled a groove into the bottom of the head and the tailstock so alignment is easy. The biggest challenge was to bore that hole for the MT3 sleeve. Compared to the tailstock I must say that the sherline tailstock resembles a toothpick. If you wish to mill tiny stuff and not to often then go for the sherline table combo. If you need a quick turning cnc solution then build one. I took a look at all sorts of tables and the ones suitable would have been precision US or European made rotary tables which would have cost me several thousand dollars and that for no other reason but backlash. Na building one or having one build is probably the best way to go as there are no affordable CNC tables. Yesterday I used it to cut a thread into a larger hole in a wood block. No way to do that with the slow turning regular tables. it has to go 'swish swish swish' and not scrp, screechh, squl. haha.

When you can manage to keep the axis running in one direction the backlash is of no factor. I like the dremel idea. I made a very simple attachment for the Dremel and my Southbend.

Re: [Emc-users] Rotary Axis Designs
There may be more elaborate versions but here is my ghetto 4th... http://www.machsupport.com/forum/index.php/topic,11044.0.htm It has no backlash. Those turntables are all garbage for cnc because of the backlash. Specially that Phase II China Junk. It all looks good and costs less but once you try and make something good with it you wonder why you fail and fail and fail. I started of with ENCO stuff and other imports and after knowing what I am doing pretty much ebay'd it of again. I used a McMasters Shaft with ready made 1inch 8tpi threading on the end to mount the chuck with that threading and I used a nut that size for the pulley. Then there are timkin thrust bearings. Nothing special, plain brute force. The shaft is solid 1,5 inches. Recently I turned a 350lbs log with that and the corresponding 'light' tailstock. Not an issue It will eat a Phase 2 4th axis for breakfast. I'd cover it better from the elements if coolant should soak it. Which is not complicated...

Re: [Emc-users] unshielded cable
Try it out first. It's not as bad as people make it out to be. If you add a capacitor and use twisted pair then you are almost certain not have problems from unshielded stepper power cables. Personally I only run step and direction and supply voltage to the Gecko's on my large gantry machine. The geckos are mounted as close as possible to the steppers and the frame does the cooling of the Gecko's. A distributed control box approach. Works flawless and has less issues. I think the steppers also work 'crisper' as the drive to motor cables are less than 6 inches... Not feet over feet... A simple metal box shields the gecko from dirt and even lowers electronic noise further. Maybe that's in idea for you as well. I use Cat5 cable for the power and the step and direction signals. Cheap and works nice.

Re: [Emc-users] Switching to Vesa Driver
When I studied Chem Engineering I had the chance to work/play on KL/KI 10's using TOPS 10 and what I learned there regarding spooling, OS, MultiTasking, Realtime... and so on... leaves the impression that everything simply went downhill from there. That machine had no specific CPU cycle. It kinda ran event driven. THAT was fast considering the discrete way that behemoth was build. Multi Ported Ferrit Memory... Awesome and I'm happy I saw all that running before it went onto the scrap yard replaced by the 'Wax Machine'. Downside at the time was that the 'adventure cave' could only be loaded after hours as it ate to many system resources 8). 'R GAM ADVENT' haha.. Good times... I am still missing the majority of functions available there. I loved the entire DEC line and the DEC Manuals are still by far the BEST organized documents with the clearest structure and language around. I still do not fully understand why all that good stuff went to manure. One would expect that in the spirit of continuous evolution and human progress the better products are pushed ahead. But CPU and OS design are HORRIBLE today. I bought a color laser lately just to figure out that it took me about an hour to fight with Vista and drivers and the 1980's error messages regarding 'not being able to print'... WTF it's friggin 2009... an OS should 'smell' a printer and provide the functions for it. Well.. Apple does it nicely.. Just looking at the RT problems we are having in the light of several GHz in the background is totally unacceptable. One can be more precise with a 4.77MHz Z80 than I am with my 2.8GHz P4 and HyperThreading. When I learned about the SMI and the fact that this 'fudged functionality' is above the NMI it explained a lot and made me nearly cough up my morning coffee. All which is necessary for looser technology to develop is a few smart people doing nothing. And Bill Gates... and all the other Carnies along that line... HA...

This allows those games that were loaded from DOS but then took over the whole system to be played on Windows 3.1 and later. Yucchhh!

I have the Shuttle pro with Mach3. Can't live without it. But a Joystick or JoyPad would do as well. Just positioning with the keyboard doesn't cut it any more once an external device has been used. I'll go and get that Logitech Gamepad. The ShuttlePro is also rather expensive by comparison. I do not plan to buy another one and I cannot take the one of my larger router.

Re: [Emc-users] Switching to Vesa Driver
I'm a UNIX guy and actually do not use spaces in anything. But if I have an input field, then I rely on the validation of the input. Stepconf allows the space in a profile name but subsequently fails to fix that up or reject it for later use as filename. I always found VMS to be the simplest OS. Also very stable. We had a server problem with a memory leak. No sources... so no way to fix that. We used a cheap electrical timer which pulled the plug every morning at 2am and restored power at 2:30. Over 5 years there has been no problem with that. Then the box became obsolete. I think they buried it next to it's trusty timer in the local landfill... sni good times Btw what happens when that dreaded 'unexpected realtime blabla' happens and it's ignored. Rough running? Steps missed? All seems to be running good now. My little Taig Mill runs WAY faster now without any hickups or rough running compared to the comparably crappy performance under Mach3. Really nice.

Re: [Emc-users] nano2count missing and subsequent RTAI problem...
Thanks for the hint regarding the herring... I took a closer look at the reference you gave and enabled the smi trick for no avail... It's still pulling sever hundred thousand ticks o0nce in a while. Unexpected failures galore It's a Dell Optiplex glx280 and I wonder if that piece might be unusable. Is the AMD architecture less problematic? And is there a list of 'approved' hardware. I guess I have to delve deeper into it. Oh, would one of those step asic cards solve the rtai problem as well for me or will that haunt me forever on that box? Cheers and thanks for the help!

I found the hardware list in the WIKI. According to that the system should work. I will switch back to the build in graphics card and see what happens.

Re: [Emc-users] Incorporation Donation [Was: Re: What's coming in manufacturing]
You do not need a bounty system or anything along that line. A commercial venture can be formed and the development of the software can be co-sponsored with services provided. Software enhancements would have to be shared as it is right now. No harm done, and the best beta testing in the world. Win win and no exploitation. The same way larger open source products are maintained. MySQL is free but one can sign up for support and other services which are incidental to the software developed jointly. I do not see a single problem with that. _ Rainer M.

Re: [Emc-users] What's coming in manufacturing
Nice comments Doug. That's the spirit! Rainer On Mon, Apr 13, 2009 at 1:14 PM, Doug Pollard dougp...@verizon.net wrote: I am am almost 75 years old and some kind of excited about this new industrial revolution that is creeping up on us all. My grandson is programing cnc for several different companies running cnc at home building products and to a lesser degree subcontracting. These little home shops don't have to pay employee healthcare nor pay corporate taxes. They can likely pay the lower capital gains taxes on what their robots, cnc mills and Fab machines build. When I think that I can download and install Ubuntu and EMC 2 buy a driver box from a shop that may have built it at home and even go so far as to build my own mill from parts that may have been built in a home workshop it's exciting. Some guy in his back yard may well cast the parts in his back yard for me out of scrap metals. WOW This not a little thing it can be huge. It may well change government or it's tax methods. It may turn out that we will do away with income tax and have to tax these products when sold in the form of sales tax. These same people will not have to drive 20 miles to work everyday and may not wear out a car every ten years making that trip. Mass transit may be an idea that has come and is now going. I have been dreaming about this stuff since back in the late 1960's when I first began to use NC and then CNC. I think the Chinese have done us a huge favor by taking manufacturing away to free up the young, smart as can be young entrepreneur that are beginning this new economy. A lot of this, I think is inspired by the writing of free software like linux. Then from there moving on to free programs like Cinelerra and emc 2. I really believe free Linux has reached a kind of critical mass that is now allowing it to move into programs that can do physical work and manufacturing. I am presently repairing microscopes but will soon be making medical parts for hospital beds, Xray machines etc. These will go freely all over the world where they are sorely needed and a big part of this will be, because of EMC 2. I could not make enough of these without cnc. I will need to make some parts to sell as well. I can't run a backyard shop without some income from someplace so I will make and sell some parts for this purpose. I have also decided that some of this money needs to go to the writing of software like Emc 2 so I plan to donate some of what I make to help develop. It won't be much money but it will help. I have never done this before because I only used free software in playing with my computer but now this same software is doing my work for me so it only seems fair to return something. Wouldn't it be something if free software changed the economy of the whole world?? I find this really exciting stuff and it seems it may go as far as you can imagine.
