Hello all; In carving these pcb's for the encoder, I only have room to clamp one edge, the back edge of the pcb. I carved a dead flat pocket about 30 thou deep and slightly larger than the raw pcb material, gouging out the left front corner so the board, when pulled left forward, isn't riding the corner, but is located by the left front edges of this plywood containing the milled pocket. But when I add a small board across the rear edge of the board and clamp down on it, the front edge of the board rises slightly, about 5 thou I'd SWAG. Is there a way to couple the y axis position to a small z axis shift so that the engraving tool will stay within a thou or so of the correct depth relative to the warped pcb's surface by driving the z deeper as y moves the table forward to work on the rear portion of the pcb. Something on the order of 5 thou down at the rear of the board, over a y travel of 1 inch, would help, a lot. I've read the pages about mapping screws, but ANAICT, that can only correct the same axis for errors and wear in that axis's drive, but I don't see a way to make z move as y moves. Is it there I'm too dumb to find it? Thanks everybody. Cheers, Gene -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

The default scale is usually pixels. You can change the display of it in a pulldown (just above the image area). You can change the default for your document in the document properties. I've made a template for my laser cutter which has a document in mm with a page size equal to the cutting area. I am not sure how wide high this board will be, but I have made what looks to be a usable starting blank page for one copy of this. I guess I am at the rank beginner stage, and can't see the tree I need in that forest of buttons. Everytime I look at a gfx composition program it seems the biggest hurdle is setting the size of the project in units to match EMC, which is running in inch mode here in the middle of the WV hills. At least I think I have everything set to inches now, and have a view that is about 2/3rds screen for a board a bit larger than an airmail stamp. Thanks for the detailed location of what I needed to modify. So, how do I draw these things to make up a PCB trace without those? To draw PCB traces I'd use one of the line tools on the left. One of them makes straight lines as long as you don't click and drag when placing points. The first thing I need to do is setup a layer that can later be removed, which contains the 12 holes I have already drilled in the board to mount the parts, and to clear the leads of the parts. Those holes are .125 in diameter and now that I have changed every place I've found px settings reset to inch, the best way to place them is via the centerpoint measurements EMC already used to position the drill before drilling. But that doesn't seem to be available, so I have to calculate the left and lower boundaries by subbing the radii, and enter the x,y diameters instead. kcalc to the rescue. :) So this is this a place circle, then adjust its properties to fine tune the location and size. But I've now drawn to a reasonable accuracy (the curser location display on the lower right only being 2 digits is a PIMA) the pattern to mount one interrupter, is there a way to copy all 4 holes and stamp them down at .340 spacings 2 more times? That would sure beat the heck out of the 3 hours I got in putting down 4 .125 diameter circles where the mounting and lead clearance holes are. Obviously I'm missing something that is going to bite me shortly, if not already. :) Silly Q, has this generated a procedure file that can be edited, then reloaded? Once I have that, then the end holes of each pattern (another layer of this drawing) need excavated to the diameter of the screw heads + about 20 thou, to a depth that is below the copper by 10 thou or so, which will insulate the screws and give me another half a thread of nut penetration. This can be done with a .125 2 flute mill. So that will be layer2. I hope to be able to arrive at a 3 or 4 layer image, each layer of which can be exported to emc as gcode and carved once the proper bit is in the spindle. Layer 1, the mounting holes. is already done. The room on the pcb left from layer1, then layer2's screw head isolation, is the room I'll have to actually build circuit traces with. It may also require a vacuum table to be built to hold it as flat as possible, and that used as a precision holding jig. I figure the first one goes in the trash, its a tool to learn how to do it. Plus the shack has more pcb material. :) If push comes to shove, it might be possible to switch to 2-56 screws, which should allow the cells to be pushed around a bit to fine tune the quadrature pattern obtained when the spindle is at speed. Some room for that is available with 4-40 screws, perhaps 20 thou. Now, off topic for this discussion.. Silly Q to the folks who did the encoder modules index logic: How to you define which edge of the Z pulse to call 0 degrees? With my wheel size limitations, that error on reversal is at least 2 degrees if it zero's only on the down edge. It seems to me that what it should be doing is looking for the edge, not the pulse, which we can diddle cell locations such that the CW edge of the z slot in the wheel always occurs when A=B=0 in the cycle. Or am I way behind the thinking here and it already does this? The integrators manual doesn't appear to get

On Sat, Jun 11, 2011 at 5:06 PM, Edward Bernard yankeelena2...@yahoo.com wrote: Sounds very interesting, Jon. I've looked at extrusion based RPS and have not been impressed with the results. Edward, Care to share any of your thoughts on this? I'm curious to see what aspects of it you've found lacking. I felt the same way until I recently saw a RepRap and some parts it had made. The parts were strong and the machine seems to be getting a lot more reliable. The part quality and finish are not what you get off a mill, and it is not super fast, but the CAM is much simpler and you can make very complex geometries without multiple setups or fixtures. As an example, there are guys selling RepRap parts kits on eBay for ~$100 like this: http://cgi.ebay.com/SAE-Prusa-Reprap-Mendel-w-PLA-Bushings-3d-printer-/190543881396?pt=LH_DefaultDomain_0hash=item2c5d4ce4b4 My understanding is that represents 20-30 hours of machine run time, most of it unattended. The existence of a decent number of vendors of these says something to me about multiple people getting these machines working well. I doubt I could come anywhere close to that with my mill, and a lot of the parts would need to be redesigned. The gears alone add a ton of complexity. The finish is definitely imperfect and has a striated/layered look and feel, and there are little blobs that sometimes stick out that can be knocked off with a file/sandpaper. Powder-bed systems definitely give a much prettier finish but the parts have very little strength. Electron-beam systems give strength and beauty but we're talking price-of-a-German-sportscar stuff now. And all of the commercial systems follow the printer ink model in terms of feedstock. The big thing stopping me from jumping in was the sense that you were lucky if you got a part one out of three runs on one of these things. It seems like the past year or two, things have improved a lot in terms of the extruder designs becoming somewhat reliable. I think their biggest problem these days is the motion control side. A few people have used EMC to run their RepRaps and seem to have gotten better results. This is just my .02c.

Re: [Emc-users] Suicide brakes on an AC universal motor?
Very good point Peter. I've had the same thing happen to me. A lot of angular momentum in a spinning blade. From: Peter Blodow p.blo...@dreki.de To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Wed, June 1, 2011 1:45:20 PM Subject: Re: [Emc-users] Suicide brakes on an AC universal motor? Gene, I suppose that your AC universal motor is an induction motor with a field winding and a cage rotor. (If it were a motor with rotor windings and a brush armature, it would be a AC-DC-universal motor and the following recipe would not apply). When the power supply is cut off, there is no magnetic field any more to exert a braking momentum. Therefore with that sort of a motor you need an additional field supply, say 24 V DC or even better 117 V one phase rectified. After power off, this voltage must be applied for a few seconds (time relay), and it will bring the rotor to a stop very quickly. Machines without this feature are not allowed to be sold or applied in Germany. The only other way would be a mechanical spring loaded brake right on the saw shaft, held open by the supply voltage as long as the motor is running. In any case, be sure that your saw blade is secured with one or two dowel pins protruding from the flange through the saw blade, preventing the left hand thread fastening nut from turning lose by the braking momentum or else you might catch the blade hopping through the shop with your hands. I have seen a what a 45 cm blade coming lose at 3000 rpm can do, and I almost experienced it myself when a (smaller) blade came lose that I used with a shaft locked in my lathe chuck when I stopped the lathe. Peter gene heskett schrieb: Greetings all; Is anyone aware of a quick dirty retrofit kit to brake an AC universal motor when the power is removed? I have a Ryobi BT-3000 table saw, which when kept properly adjusted, does a fine job. Its motor package is a universal motor that drives the blade with a gilmer belt. I nicked a finger on my table saw blade yesterday because it was still spinning 2 or 3 seconds after the kill switch was hit. Not seriously, just a slight nick that bled for 2 minutes, and is a red spot about 1/8 in diameter this morning. If practical, I would like to replace the existing power switch with one that is both handier because its not such a long reach under the table to hit it, and which shorts the motor in the off position, or at least applies a power resistor dummy load to it, commonly referred to as suicide braking.

I apologize to everyone, who will consider this email as totally inapropriate for this mailing list Jack, I started typing this as a private answer, but it got so long that I decided to share it with others - at least Dave is interested too. First of all - this is only my personal opinion. Secondly, I was only 7, when USSR fell apart, so I have not seen much of those days with my own eyes, but I have been watching people for last 20 years and listening to stories of parents and other people. It started from the fact that in communist there was no private property. Everything - factories, shops, real estate - belonged to state. So there was no motivation to take care for their surroundings, for the place they lived in, because everywhere was that this is not my property, so I do not care. It does not matter that I live here attitude. And this attitude is still there in many elderly people and also in their children, because that is what they have been taught in their families. One more consequence of no private property condition was that nobody was really interested in maintaining maximum efficiency in operating different organizations, especially factories etc. In capitalism there is owner of company, losses of company are his/her personal losses, so he/she will implement harsh procedures just to ensure that company is operated efficiently. In communism there was not such attitude. Manager of organization was interested to fulfill the plan - economy was planned in 5-year cycles. Planned was everything - how much wheat should be grown, factory output etc. Supply was not connected with demand, almost every commodity was deficit. All the things were available at first to party members, then to people that were involved in distribution. So it was important to have the right connections otherwise it was hard to get anything. One could not just buy a car or an apartment. My grandma got a car after 8 years waiting in a row and I was told that it was quickly. And one important consequence of the fact that nobody was really interested in maintaining maximum efficiency is that it was common practice to borrow different resources from job place. All You had to do was to give a share to the responsible guy. This stealing was so widesperad that people even now consider it as a normal behavior and I find it to be a big problem. BTW at least in my country there are many people that say - it was better in USSR than now in EU. The arguments are that people had jobs and people had more money. Kind of true, because there was law that unemployed people could be punished. And there were no things to buy or spend money on, so people had feeling that they had it. Now with open market people are earning 4 times more and spending 7 times more. Other big problem is that it was totalitarian regime. Any initiative could be considered as anti-soviet activity, for which there were harsh punishment. And there were many manufactured cases with no real evidence. Stalin is the author of very famous phrase, which is hard to translate, but the meaning is:Give us a person, we will find a clause (in law, under which that person will be convicted). That also added to that I do not care attitude. Viesturs -- What Every C/C++ and Fortran developer Should Know!

The tilted it to 44 degrees, one less than the OEM grind. Then mounted a dremel diamond disk in the mill and lowered it till it was about touching, turned the spindle on started sweeping. The first blade had about a .015 taper lengthwise, so it took about an hour of making a couple of sweeps, lowering the wheel a thou, repeat till it was suitably bright polished the full length of the blade. Very fine dust could be seen falling away from the spinning disk. On removal from the jig the first time I found it had wiped a wire edge over the cutting face that was about 20 thou high, and it took me about 20 minutes with a Smiths hard Arkansas stone to remove it. The blade didn't feel all that sharp when that was done, so I returned it to the jig went down another thou about 5 times, this generated a new wire edge but it came off easier. And the blade felt fairly sharp, so I re- installed it, setting it about a thou proud of the outfeed table. Wash, rinse, repeat for the rest of them. The wood I'm trying to straighten is well seasoned, clean white ash. I thought when I bought this jointer 3 years ago, that it got dull a heck of a lot faster than a little 6 table topper I also have, but that has alu tables and they'll dirty the wood. I thought as I was trying to sharpen these blades that they looked nice, but weren't much harder than some of the wheel weight lead I occasionally pour plinkers from. Fresh blades are $59 a set of 3, $123.94 from the only place that stocks them, (I ordered 2 sets since Lowes isn't stocking them and when I found that this afternoon I did a bit of grumbling at customer service, I mean I did buy it from that Lowes about 3 years ago. It won't do any good of course but made me feel better.) which to me says they ought to be pretty decent steel. These are the original blades, did I get some junk blades when I bought this thing, or is there something wrong with my sharpening technique? These were nicked and leaving lines from the nicks before I had run a 34 piece of already clean ash 2.25 wide, over this from the freshly sharpened state.

Re: [Emc-users] EMC2 and Ethernet
My very humble opinion is that the Beagle board (or equivalent) would be the the best solution.

Unfortunately the module is sealed in silicone so I can't get to the potentiometer leads to control it externally. I will say that it gives me speeds down to a few thousand rpm with plenty of torque.

We believe that the largest impediment to success is the lack of a full scope supplier. We feel that the mainstream machine builder community, meaning hobby, professional, and OEM, remains outside the open source community. Furthermore, we feel that the solution is not to try and bring machine builders into the open source community, but rather to bring complete solutions to machine builders. We propose the creation of a company which delivers EMC based solutions, essentially the Red Hat of CNC. To that end, we will finance such a company. *Perspective:* There are quite a few hobby oriented suppliers, based on Mach3, TurboCAD, and other solutions, which offer everything including ballscrews, motors, drivers, and circuit boards. These companies serve their customers well, but they do not come up to the level of professionalism that is necessary to attract serious commercial machine builders. There are mid-level suppliers, such as Flashcut, CamSoft, or Centroid, which offer reasonable value but cannot provide the security, vendor independence, or continuity of supply, which would be available with a more open technology. Of course the 800 lb gorilla is Fanuc, having sold 2.2 million control systems. While offering the ultimate in performance, Fanuc solutions come with minimum vendor independence and dismal ROI for those only needed mid-level performance. We believe a full service, professional grade supplier, offering complete control systems solutions, can be an effective competitor and is sorely needed by all levels of machine builders. We are not proposing open source hardware, but rather combining open source software with support and conventional industrial components to develop full spectrum solutions. This is not a matter of welcoming machine builders into the open source community; rather it is an issue of bringing the resources and value of open source to the market, offering attractive ROI to both customers and investor. *Details and How to Proceed:* We are looking to invest in a start-up business which meets the general goals as outlined above.

I'm starting up a blog at http://ckcnc.wordpress.com to document what I'm working on. There's nothing much there yet but there will be more over the next couple weeks. I've got all the pieces working, what I need to do know is tighten everything up. I'm designing a board that will have two encoders (MPG and Spindle/FRO) and switches for axis and scale selection, continuous feed, and cycle start/pause/single block, plus maybe a few extra depending on what I can squeeze in. What I'm playing with right now is adding an LCD display that could act as a remote DRO, which would be really nice to have on a pendant. It's tempting because a 20x4 display can convey a ton of information with 6 output pins from the Arduino. But, I am running tight on pins as it is, and I feel like I'd prefer to have hard LEDs for things like the axis and scale selections, rather than forcing people to read an LCD. Of course, a Max7219 -segment LED driver gives me 64 outputs from 3 pins, so maybe if I can get both to work more power! But I'm also unsure about how much data I can reliably push through the wire. I can do all the core stuff with single-byte messages very easily, but a DRO message requires 7 for a value like X12.345 (using ASCII), and it gets messier if your messages have different lengths. So I'm just not sure how far I am from running into contentions between, say, HAL pushing position updates to the DRO, and the MPG wanting to move the axis. In principle there's plenty of bandwidth at slightly higher speeds like 19200 or 57600bps, but my sense is these can be sufficiently less reliable that I'd prefer to be really conservative, especially if I start selling the board. Anyway, for your hacking in the meantime, my main suggestion is to build the stack up in stages like this: - Write your Arduino sketch with one or two inputs and outputs. Test it with the serial monitor until it's doing exactly what you think it should. - Write a minimal Python program you can run from the command line, and make it talk to the Arduino, again using the serial monitor to verify everything. - Add the HAL component to the Python program, and test it from the command line with halrun to verify it's setting pin values as you expect. - THEN, and only then, link it up with your GUI of choice. Basically, my experience was that the vast majority of my problems were actually in getting Python and the Arduino to communicate as I wanted. Getting Python to communicate with HAL was almost trivial.

Currently, the way I'm doing it is to have the arduino read the encoder outputs and convert them to a signal which represents one pulse in the CW or CCW direction. The Python script receives the signal, and then jogs the appropriate axis in the + or - direction for 1/10th of a second. So far, the motion seems smooth (on screen, I haven't tried it on one of my machines yet), but I'm wondering if there's a better way.

Re: [Emc-users] Engraving Tools.
I'd definitely go for a more substantial spindle. Proxxon and Metabo make excellent small spindles or you could use one of the better grade trim routers (Bosch Colt, Dewalt, Porter-Cable, etc.) Also check out the precision collets available from Precisebits.com. These will greatly reduce the runout and enable you to use small diameter bits. -Greg From: Speaker To-Dirt speaker_2_d...@yahoo.com To: emc-users@lists.sourceforge.net Sent: Fri, September 10, 2010 1:20:11 AM Subject: Re: [Emc-users] Engraving Tools. Hi All: Here's a question esp for the XY routing table folks. What's a good 'dremel' tool to survive the side loading of engraving on alumnium? I want to make face plates for electronics enclosures, so text, numbers, outlines etc. That means small end mills and high RPM's. Maybe even nameplates and the such. I'm designing a clamp on mechanism to allow me to mount a 'dremel' tool shotgun on my z pillar and just vary the z axis like +/- 100 thau at most. But that side loading seems to me would tear a dremel apart. I see the XY table crowd uses them. What approach should I take? The $30 special from Horrible Fright and just blow through them? Or sink $100+ into something that will last me more than a few projects? Your thoughts?

Re: [Emc-users] Jog under PAUSE / tool cnange
Bravo John! That was not only the best description I've read of EMC's workings but also one of the more thoughtful and well constructed rants I've heard on this or any other forums. As my own rant I have to say that I've shaken my head several times after reading some of the demanding posts lately. I am a noobie at this but I'm astounded at the functionality of this free software as well as the level of support available from its developers and users. The biggest limitations I've encountered thus far are my own. It's my hope to continue to learn and become a contributor to this wonderful software myself.

How about this excuse: (Note: to understand this, you will have to think like a developer for a while. That means you need to understand the basic internal architecture of EMC2, and you need to think in detail about how to implement what you want, not just what you want the machine to do.) First: Basic EMC2 architecture. EMC consists of several levels. From the top down, it goes GUI, Interpreter, Motion Controller, HAL. (I'm leaving out a lot, but this is still going to be too long, so forgive any oversimplification.) The first two levels are normal user space programs. Like all normal programs, they are at the mercy of the operating system and any other programs that are running at the same time. When the computer gets busy, regular programs temporarily stop or slow down while the operating system or another program does something else. Everybody has experienced that with everyday programs. You click on something that normally happens instantly, but it takes a half-second or a couple of seconds instead. That kind of thing happens all the time, usually for a tenth of a second, or a hundredth, and you never notice, but it is there. Not a big deal with normal computer programs, and not even a big deal for the GUI of a machine tool. But not acceptable for the low-level motion control. To avoid this problem, EMC runs the motion controller (and HAL) as realtime processes. When a realtime process is configured to run every 1000th of a second, that is exactly what you get, no matter how busy the rest of the computer gets. (There is still a small amount of variation, measured in microseconds, but we're ignoring that). The motion controller runs 1000 times a second. Most of the time, all it does is calculate a new position a little farther along the line or arc described by the current line of g-code. But sooner or later that line or arc ends, and a new one starts. When that happens, the info about the next line of g-code MUST be available. That info comes from the g-code interpreter. But what if the interpreter happens to be right in the middle of a 1/10 second delay? EMC solves this problem with the motion queue. The queue holds a couple hundred motions (lines, arcs, etc). The interpreter runs as fast as it can, turning g-code into simple motions and putting them in the queue. The motion controller takes them out of the queue and moves the tool. What this means is that the interpreter is usually many lines ahead of the motion controller. The interpreter applies work offsets to each move. It translates units from whatever the program uses (inches or mm) to machine units. It applies cutter compensation and tool length offset. It breaks canned cycles down into individual lines and arcs. After doing all of that, it puts the lines and arcs into the motion queue. The motion controller pulls lines and arcs out of the queue and makes the tool move along that path. A particular line or arc might sit in the queue for a couple tenths of a second, if you have a program that consists of many short moves. It also might be in the queue for minutes or even hours, if the program has very long, very slow moves. A short program can be completely interpreted and in the queue before the tool ever touches metal. All of the above information is background - a very simplified version of what happens as EMC runs a program, just enough to explain what the motion queue is and why we have it. Now lets think about implementing pause/jog/run. Steve has put his thoughts into the wiki page at http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ManualWhilePaused He says EMC need only remember the axis positions it stopped at and on resume should always do a combined move back to that position. So, how can we do that? I assume he doesn't want to wait till the end of a line or arc to stop. If the tool breaks or swarf wraps 1 inch into a 10
