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 To: emc-users@lists.sourceforge.net Sent: Fri, September 10, 2010 1:20:11 AM Subject: Re: [Emc-users] Engraving Tools.

Re: [Emc-users] Help! Axis runs hidden
If nothing is really wrong, you can find out by using the fg command from a terminal.

Re: [Emc-users] Rtai problem on install
Gentlemen, I performed a new install of 10.04 Desktop. I then installed EMC2 using the shell script. I then downloaded the source with git and compiled. This install runs fine. I have had zero problems with it. I performed an upgrade from 9.1 to 10.04. I then installed EMC2 as in the prior example. I cannot make either the shell install or the source/compile install run. I haven't tried very hard but I don't seem to want to. If I need it to run I will do a new install of 10.04 and see how that goes. Just sharing my recent experience.

Clicking on those should bring EMC up on the current desktop. But, maybe the problem is Axis is not starting for some reason, but the rest of EMC is not completely shutting down. You may need to start EMC from a terminal window so you can see any error messages. in your EMC directory, there should be a subdirectory scripts, so you run /scripts/emc and it should start up, and report some info in the terminal window. You'll have to determine what is on your particular system.

[Emc-users] inverted tripod question
Hallo, first of all thanks for all the work done with emc2, and for ubuntu 10.04 emc iso. then.. i've a problem using the tripod setup. i've changed a little the kins and ini to have 4 legs, but the problem i have is the same as in a tripod: as i home all my axes, i change into world mode and emc2 assume i'm on the positive Z above the XY plane. then if i move the point 'down' to reach the same position under the XY plane, and i re-home, this time emc2 thinks the point is under the XY plane. How can i tell mr. Emc2 that i want my point to be ONLY under the XY plane? assume that my setup is the same as Alex Jony's Toy. i did that with four legs, but i repeat..it's the same.

Here's one good reason to . My latency under 8.04 was 13000, under 10.04 it's now 8000. I installed as dual boot and just copied my emc config folder over. All works fine. Onboard NVidia graphics now works properly without a crippleware driver at any resolution up to 1600x1024 instead of being limited to 1024x768.

Gene: Sorry to hear your tale of woe. Regarding the Radeon driver, have you read the helpful remarks at https://help.ubuntu.com/community/RadeonDriver ? Does dmesg have anything useful to say? I endorse Andy's comment about the D510M0 board. Just remember that, unlike its predecessor the D945GCLF2, it does NOT bring out the parallel port lines to a connector on the backplane. You'll have to work something out (shouldn't be too hard for someone who first rebuilds his dvd reader on the fly!). The D510M0 is a mini-ITX board 170mm x 170mm.

[Emc-users] Rtai problem on install
Hi, I have tried to install the new EMC2 on an existing installation of Ubuntu 10.04LTS using the .sh script, however, I have hiot a problem which i don't quite understand. First let me say that the Ubuntu and EMC2 installation has been upgraded several times and I suspect that the problem is caused by my wetware failure in deleting things that I shouldn't have - or not deleting things I should have.. The EMC2 installation ran to completion but left me with a 'broken' package - rtai and so EMC2 won't run even in sim mode (earlier versions seemed to run the sim modes without rtai being installed at all...). When I try to fix the broken package using the 'broken' filter on package manager, I get the following message... E: /var/cache/apt/archives/rtai-modules-2.6.32-122-rtai_3.8.1-linuxcnc1_386.deb: trying to overwrite '/etc/udev/rules.d/99-rtai.rules; which is also in package rtai-modules-2.6.31-21-rtai 0 The 99-rtai.rules file contains... #RTAI: rtai_shm KERNEL == "rtai_shm", MODE = "0666" #RTAI: rtai_fifos KERNEL == "rtf[0-9]*", MODE = "0666" I'm pretty sure that the 'rtai-modules-2.6.31-21-rtai' has been uninstalled at the same time as the 2.6.31-21 kernel - when it was upgraded to 2.6.31-22 but I'm not absolutely certain. If I just delete the 99-rtai.rules file will the upgrade to rtai-modules-2.6.32-122 automatically create a new file or will this break things altogether?

That shouldn't be neccessary, if you are running your tool change component and the edge component in the servo thread.

Any positive value (even 1 nanosecond) will result in the component producing an output pulse that is at least two cycles long, which would result in a double count. Zero is the default value for that parameter, but you might be setting it to something else, or something might be broken - verify the value with halcmd show.

[Emc-users] Help! Axis runs hidden
Hi guys, today I started my machine and EMC2 didn't start automatically as all the days (it is in the start-up section) so I tried to launch it manually and I got the error "ECMC2 is still runnnig. Restart it". So I realized that the process was still active. I killed the running processes and restarted EMC2 but nothing happened. The problem is that I cannot see Axis interface... Axis and EMC2 are listed in the processes list (sleeping) but I cannot see the grafic interface. I tried to stop the processes and restart them but nothing changed. I'm running Ubuntu 8.04, EMC2 2.2.8 All the other application are running correctly, only Axis is hidden. What can I do?

Re: [Emc-users] [OT] Interferometry
Getting two flats aligned well enough to produce that first fringe is not trivial. It takes fine adjustment controlling elements. HeNe lasers go along way to aid this effort. Reflections and all. I have a Davidson D304, 5.5" aperture unit here in the home lab. Not useful for any machine tool application, but good for qualifying the flats one might use.

Clamps sets are not precision items. If you measure your 1" thick clamps with a micrometer, I wouldn't be at all surprised to find that one clamp is 1.004, and another is 0.998. I'd only be a little surprised to find that a single clamp is 1.001 at one end and 1.003 on the other end. A dowel pin works great for this - very precise, and you can simply push it against the side of the tool, then raise the tool (or lower the knee) slowly until the pin rolls under. Don't lower the tool onto the dowel (or a clamp, or any other piece of metal). It doesn't take much to chip the edge of a carbide tool, or dull a steel one.

Use halscope to observe the input from the prox. Zoom in enough to
clearly
see every single servo cycle. (set the horizontal scale to 1 or
2mS/div)
Maybe it is generating a double pulse? or a pulse with a glitch on the
leading edge?
Use halscope to observe the output of the edge component. Maybe it is
broken and is triggering on both edges? Maybe it is broken and is
making
a two-cycle long pulse?
Use halscope to see exactly when and by how much the count advances.
You can trigger on the count itself, so it should be easy to see the
event. If the count is only used internally in your component, and
isn't visible to halscope, then at least temporarily make it a pin.
Does it advance by two during one servo cycle? Or does it advance
by one in one cycle, and advance again on the next cycle?

That code seems sort of OK to me. "Sort of" meaning, I can't tell
why it would count twice. There is another possible problem with
it though:
Suppose the Count signal and the Zero signal arrive in the same
servo cycle. In the cycle when both signals arrive, the first
conditional is true, and the second one is skipped. Result = 1, OK.
Now suppose the Count signal arrives one (or more) cycles before the
Zero signal. In the cycle where the count signal arrives, the second
conditional is true and you get an increment. A few milliseconds
later the zero signal arrives, the first conditional is true, and the
result is 1. Still OK.
Now suppose the Count signal arrives one (or more) cycle _after_ the
Zero signal. In the cycle where the Zero signal arrives, the first
conditional is true and the result is one. But a cycle or two later,
the Count signal arrives, the second conditional is true, and the
counter increments. Result = 2 which is wrong.
If the zero and count edges happen very close together, it will be
impossible to guarantee correct operation. I'd look at both inputs
with a scope (hal or real storage scope) while running the chain
around many times. If there is a clear and repeatable interval
between the two edges, then you can code accordingly. But if they
are too close together to reliably ensure that one always comes
first, then I'd consider using a rising edge to count, and a
falling edge to reset, or something along those lines. You want
the count to happen first, followed by the reset.
Personally, if I was writing C code anyway for this component, I'd
incorporate the edge detection in the component to avoid having a
couple other components and signals in my HAL config. Something
like this:
static int oldPotZero, oldPotCount;
// detect rising edge of count
if ( PotCount && ! oldPotCount ) {
toolpotcount = toolpotcount + 1;
}
//detect falling edge of zero
if ( ! PotZero && oldPotZero ) {
toolpotcount = 1;
}
// remember current state of inputs for next time
oldPotCount = PotCount;
oldPotZero = PotZero;

Re: [Emc-users] tool change component
when the zero return and count pots trigger I get 3 as the first count on the next pot count the result is 5 then 7 then 9 until the zero return hits again and resets to 3 I think I can probably fix the first three count by triggering the count prox on rising edge and triggering the zero pot on a falling edge. they are certainly on at the same time and appear to come on at exactly the same time I could also move the zero trigger to create a trigger time difference my main question is - Why to I count 2 for every pot trigger? -- dos centavos -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

Re: [Emc-users] tool change component
they are separate triggers and pots
they trigger very close to the same time but the zero return triggers only
once per complete chain cycle
the pot count triggers 30 times per chain cycle

Does the "zero" pot also trigger the "PotCount" pin?
I would be tempted to put the edge detector into the comp, to make the
HAL simpler. That would also allow you to mask PotCount on PotZero.

[Emc-users] tool change component
Gentlemen,
I have a prox for tool change zero return (to home the chain of pots) and
a prox to count the pots during chain motion
The chain moves slow - between 1 and 2 pots per second
The chain matrix carries 30 pots
This is a random tool changer - the pot swings down and a transfer arm
swaps the tools between the spindle and the tool change pot
I want to reset the count to 1 every time the zero return dog passes the
prox
The following code resets the count as I wish
I have an edge component set up to trigger on the falling edge of the pot
count prox signal
The following code counts two every time the pot count dog passes the prox
if (PotZero) {
toolpotcount = 1;
} else if (PotCount) {
toolpotcount = toolpotcount + 1;
}
I have removed all other logic from my component - this is the entire
logic in the file at this time
What am I missing? (except for intelligence) :)
I trigger the pot with pliers and get the same results whether I trigger
quickly or hold the pot on.
thanks
Stuart

What about adding a G64 P... or similar? Even with a very small P of a few hundredth of a millimeter it improves the situation significantly. I have some experience on the 840D and I do not think that it behaves differently. If you run the 840D in G60 mode (default), it will also stop after each G1/0 move and re-accelerate. So I do not think there's a difference between 840D and EMC here. The machine does what you program. So if you program a stop every 5 microns, it will completely halt every 5 microns. -- Greetings Michael. -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

> The basic question I guess is would EMC be able to provice the same tool > path quality as the (lower end) Siemens or Heidenhain controllers? You should run EMC in simulator mode, and use halscope or halstreamer to record all the joint positions to disk. Then you can analyze this data later for correctness/smoothness. It is fairly easy to "choke" the EMC interpreter/traj-planner with G-code which consists of many many short G01-segments. It could be argued that these should be filtered to longer lines, arcs, biarcs or NURBS G-code, but if you have a CAM-program that only outputs these short G01-segments this could become a problem. Even with a hobby mill this is an issue. We have 5m/min rapids on our machine and when programming a contouring operation at say for example 2m/min feedrate, if the CAM-program outputs lots and lots of short G01-segments the EMC interpreter/traj-planner will not handle it well and the actual feedrate may be 1m/min or even lower. You should be able to test for this in simulator mode (see above). Improving the trajectory-planner is not an easy task. I think the consensus reached last time we were discussing this is that it is a very hard task indeed _unless_ some restrictions are added. For example restricting traj-planner to only 3-axis trivkins and/or restricting feed-override to 0-100% (not >100%). Also I think there is a restriction of one G-code block (or canon-command) per servo thread cycle. If you run a normal servo-thread at 1ms that means 1000-lines of G-code per second (in theory). If your CAM-program outputs more than this you will get the slowed down feedrate I mentioned above. As mentioned by other posters this is a problem you rarely encounter with hobby-grade machines because it only occurs with "bad" CAM-code which consists of the many many small G01 segments and with high-speed machinery where you want to cut at 5m/min or 10m/min (or more!). When you have this kind of cash invested in the machine, the tooling, and are under time-pressure to have to run your machine at 10m/min then suddenly I think investing another 10k or 20k in a pro controller is not a problem... (contrast to sitting down, learning all the innards of emc2, learning trajectory-planning math/geometry, and attempting to write a high-speed traj-planner for EMC2) Anders -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

Hi Ulf > If you have money for a dmg machine of this new age, maybe emc is not > what you need. That's what I'm trying to figure out. At present state I do not really know how much EMC might save me, probably 20k EUR. Depending on how difficult the conversion would be this could be worth it or not. I'll certainly lose a lot of nice features of the professional controllers, but mostly features that I don't need. But it would certainly take a few weeks to do the conversion. > The Siemens 810 is fully digital and fitting emc with the other digital > controls would require much rewiring. That's a good point, I have to make sure it's possible to link the digital servo drives to EMC. I didn't think of this problem yet, because I never worked with these new digital servo controllers. Do you have any details on that? > It would be better and simpler to upgrade the 810 to 840.

I thought about that, but having the machine under the manufacturer warranty is a good thing. Of course I will lose warranty as soon as starting the conversion, but I could wait for a few month and use the new machine in its original 3+2 set-up at first.

Re: [Emc-users] Run in place
As Jeff say I just forgot to enter: "source scripts/emc-environment" Now it works. Manuals are pretty bad (well not accurate). I know that kepping manuals up to date is near same job as programming itself. But as project (emc2) is maintained with so many developers kepping documantation is even harder. I hate organization of emc2 webpages and support. It's so spreaded that this make confussion. We have mailing list, forum, IRC ... emc2 page at linuxcnc and wiki and ... ... ... I think that now is time to join all that together in same place and to keep only one of 'delayed support as forum or mailing list' and live IRC. Near same is in code. There is so many doubled things and that just confuse users. Just one example (I know that as it's done for me.) In documentation the stepgen has 14 different modes. That's just not true. It's 15 different modes as one is added half year ago. And if someone look in source the same thing appear. In header where types are explained the type 15 is missing. I find just two lines burried in code that talking something with type 15. Near impossible to find it. And type 15 can be substitute for types 3 to 14 too. So kepping doubled functionality is in question. To keep or not to keep. Of course if that types are deleted the all users (using it) need to change one line in hal.ini I must stop as I use EMC2 and I think I got a little out of toppic. Na 8.9.2010 20:32, K.J.
