[Emc-users] InfraRecorder google Chrome download warning?
I needed a windows ISO burner and went to the LinuxCNC site because I had gotten one there before. I found infraRecorder on LinucCNC.org here: http://linuxcnc.org/docs/html/common/Getting_LinuxCNC.html#_burning_the_cd When I downloaded, it linked me to downloads.sourceforge... and once it started downloading, Google Chrome put up a RED screen and halted the download. Are there any issues w/ Sourceforge and google? I ended up downloading anyway and I didn't get extorted yet... Lastly, there are some dead links on the linuxCNC Download page: http://www.linuxcnc.org/index.php/english/download I looked briefly to see if I could edit and didn't find a way. The problem is that the links point to EMC and not CNC in the getting _LinuxCNC: http://linuxcnc.org/docs/html/common/Getting_LinuxCNC.html#_burning_the_cd Regards, Mark -- Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.

[Emc-users] Debian Wheezy Monitor Blank
I got a hum dinger... I was using pnnconf to setup my 5i25-7i77 and I couldn't reach the entire pnnconf window on my system using a 17 lenovo monitor. I dragged the window 'up' to click the buttons on the bottom, but the next window I couldn't reach the top and seemed to be stuck. I tried reducing the size of the window by grabbing the sides, but that just moved the window around and sometimes not in the direction I wanted. I got the bright idea to increase the screen resolution and found the Display utility from the wheezy menus. I changed the resolution fine. After that bright idea, I got stupid real fast. I noticed two monitors listed, the lenovo and a generic. Also, there was a check box that said something like, Don't use this display. I figured it might turn off the lenovo and default to the generic monitor listed. I'm a curious sort and thought it would be worth trying. Why I checked that box I have no idea, but after checking it, my monitor went blank and the green on/off LED turned Yellow... I have rebooted and I can login and as the window environment opens, but my monitor goes blank and the LED changes from green to yellow. I tried another monitor from Dell, and the same thing happens. I noticed that you can login to a xsession of xfce session, neither made a difference. Any idea on how to get my display back? I should be laughing at this, not really so much. Thinking out-loud, I don't have anything on that system, so a re-install is probably easiest? Especially for a linux-handicapper like me. -- Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.

Easiest way is to create a new user and startx on that user so you drop all previous configs. then just copy you home folder setting files to your old user again.. // A Erik Christiansen skrev den 2015-03-25 08:36: On 24.03.15 22:51, Mark Johnsen wrote: I got a hum dinger...

Re: [Emc-users] InfraRecorder google Chrome download warning?
Andy - thanks for the reply. I thought it was a little strange to get the red screen and wanted to make sure the community was aware of what's going on there. I hadn't seen that before from that site. I agree w/ the shady download adverts, they're prevalent at source.forge and cnet's download.com, but I hadn't had chrome stop that before. Once you're past the adverts, then you have to watch about the rogue ad-in installs like ask.com, etc. Those are on the same level of evil...

I have 2 strands of cat5 running across the back yard, one of which was 6 years old in 2010 when a 112 mph direcho came by and knocked down most of the bigger trees, all my privacy fence, + took some of my roof and generally made a heck of a mess of the whole neighborhood.

Re: [Emc-users] Ladder logic documentation [Was: Simple, adjustable timer]
As an older, not that aware, blonde, Polish, left handed, engineeer. I can't keep track of more than one thing at a time. Out of self defense working on PLC's and yes discrete hard wire ladder logic in machine tools, (since about 1965), I only use normally open switches with PLC's. It reduces the task to something that I can understand. The exception to this rule is the safety loop, which should consist of nothing but normally closed switches, which is never tied into the PLC anyway, or it shouldn't be, my apologies to Pilz and a few others that make intrinsically safer PLC's. Invert the signals in one logic level only! When you are working to a deadline to get a piece of equipment running again, there are enough stress/distractions, don't make the task more difficult. A further concern that comes to mind is whether another person can follow you and do the repair? And if the repair/upgrade happened more than two weeks ago, that person is you! and you won't remember what you did, so you will have to relearn the logic More self defense I only use power on timers in PLCs, if I need something else, I build it in the PLC logic, it does no one any service to combine timer types in a single PLC program to save a few lines of programming. - Original Message - From: emc-users-requ...@lists.sourceforge.net To: emc-users@lists.sourceforge.net Sent: Tuesday, March 24, 2015 11:10:26 PM Subject: Emc-users Digest, Vol 107, Issue 58 Send Emc-users mailing list submissions to emc-users@lists.sourceforge.net To subscribe or unsubscribe via the World Wide Web, visit https://lists.sourceforge.net/lists/listinfo/emc-users or, via email, send a message with subject or body 'help' to emc-users-requ...@lists.sourceforge.net You can reach the person managing the list at emc-users-ow...@lists.sourceforge.net When replying, please edit your Subject line so it is more specific than Re: Contents of Emc-users digest...

[Emc-users] Velocity closed loop + Position losed loop on an axis
Hello to all! I just managed to turn the second motor of my machine (another AC motor with a Powerflex 40 drive) and works just fine for positioning the part. Tomorrow I'll be uploading some videos. Although I need to do some fine tuning on both the rotary and the linear axis I was thinking about a concept to improve the accuracy of the servo loops. As I have seen on many machines including the Mazak that we have here, the servo systems close the velocity loop within the servo drive, and then the CNC applies a voltage to control the velocity of the motor based on the PID of the position loop. So as I see it, it's like there is one pid nested inside the other, or sort of. Now the VFDs that I'm using can close the velocity loop but I would have to use a special module for that. My question is, based on your experience. Could this improve the accuracy of the joints? I guess this could be done within LinuxCNC without closing the loop on the VFDs.

Re: [Emc-users] Velocity closed loop + Position losed loop on an axis
Hi Leonardo. If you want to perform a closed loop position system as you said you need the inner speed closed loop. I do believe that can be quite difficult to perform both closed loops within LCNC with the expected accuracy. The VFD that you are using is a sensor less vector control type (that is why you have to close the speed loop outside the VFD). This kind of VFD are not the right product to run a servo system (as you already know) also because you should drive an asynchronous induction motor that is not usually suited for that porpouse. I'm not a LCNC guru but at least I've always used a vector VFD with encoder feedback tied from the motor to the VFD with the encoder simulation feedback connected to the axis module .

Re: [Emc-users] Debian Wheezy Monitor Blank
I made some progress, but still struggling. The Ctrl-Alt-F1 opened a terminal, but maybe not the right kind? Whenever I issued the xrandr command (other than man xrandr), I got Can't Open Display Found two outputs VGA1 and LVDS1 in this file /var/log/Xorg.0.log and this coincides with what I saw in the monitor window. These are the 'output' types and if the xrandr command worked I'd issue something like: xrandr --ouptut LVDS1 --auto Someone mentioned xorg.conf, but I could not find any xorg.conf files in the etc/X11 file. In some of the info I found, the xorg.conf was replaced in this or a recent version of Debian by something else and confuses me.

Re: [Emc-users] Velocity closed loop + Position losed loop on an axis
To get higher accuracy you need more accurate measurement, some extra resolution above the accuracy is also useful. For better dynamic perfomance it may make sense to close the inner loop if the inner loop is faster than the outer loop. If the electic response is much faster than the mechanical response then there is rather little to gain from faster control loop. If motor inductance is around 1mH, applied voltage is 48 volt and current is 10A then U=L*di/dt = dt = L*di/U = 1mH*10A/48V = 0.2ms = 200µs is the time to change motor torque from zero to maximum which put an upper limit on dynamic response, there is also a rotational speed dependent back emf reducing available voltage. If you do not like the math. Change servo loop peridicity adjust control loop and see if it make any real difference.

If you do not like the math. Change servo loop peridicity adjust control loop and see if it make any real difference. Nicklas Karlsson If I can butt in here Leonardo, when I was setting up the spindle speed servo in my toy lathe after switching from a non-linear and failure prone driver to drive the 1hp treadmill motor my 7x12 now sports, to a slightly modified version of the Pico Systems servo driver, and keeping in mind I am using one of Peters 5i25 interfaces, which means I no longer needed a base thread in the setup. But the speed servo was hunting badly enough to keep the back gears in the headstock rattling pretty good when the servo thread was running at nominally 1 kilohertz. I had to reduce the P in the pid to the point it was essentially worthless at sub 300 rev speeds. So for SG, thinking the control was too slow, I did a rockhopper diagram and re-arranged the hal file so that I was doing a straight fall thru of the control path so it was not wasting a period or more because it was out of order when the modules were in the wrong order. That helped but the amount of P seemed to be limited yet, so the only other way to get a faster control loop was to raise the servo thread speed. Nominally 2 kilohertz made an obvious difference, and at 4 kilohertz, it was lots quieter. So that is where it has been running at for several months now. P in the speed PID is now high enough that I can peel off a pretty good sized string of blued steel at 150 revs, or even a dimly glowing string at 500 revs, which gives a more better finish. My $0.02. Works well here, might not be worth the electron wiggle to send it to someone else. The phrase YMMV applies here.

I just managed to turn the second motor of my machine (another AC motor with a Powerflex 40 drive) and works just fine for positioning the part. Tomorrow I'll be uploading some videos. Although I need to do some fine tuning on both the rotary and the linear axis I was thinking about a concept to improve the accuracy of the servo loops. As I have seen on many machines including the Mazak that we have here, the servo systems close the velocity loop within the servo drive, and then the CNC applies a voltage to control the velocity of the motor based on the PID of the position loop. So as I see it, it's like there is one pid nested inside the other, or sort of. Now the VFDs that I'm using can close the velocity loop but I would have to use a special module for that. My question is, based on your experience. Could this improve the accuracy of the joints? I guess this could be done within LinuxCNC without closing the loop on the VFDs.

Possibly not, as the trajectory planner already does that (to within the limits of the blending tolerance). However, I think I have heard of software that can do the same thing. You can draw an arc through any three points, but there is no guarantee that successive arcs generated the same way will be tangential to each other, so there needs to be some clever manipulation to make the arcs as big as possible to see the potential advantage. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.

Do you mean to extract velocity from the encoder and then feed it out a DAC channel to a velocity servo amp? This is what almost all FANUC controls do, and a few people are doing this with LinuxCNC. I think Chris Radek is doing this on his machine, and John Kasunich and Chris Kelley at Tx/Rx Labs in Texas got this working on their PowerHawk mill.

Re: [Emc-users] Velocity closed loop + Position losed loop on an axis
2015-03-25 21:12 GMT-03:00 Gene Heskett ghesk...@wdtv.com: If I can butt in here Leonardo, when I was setting up the spindle speed servo in my toy lathe after switching from a non-linear and failure prone driver to drive the 1hp treadmill motor my 7x12 now sports, to a slightly modified version of the Pico Systems servo driver, and keeping in mind I am using one of Peters 5i25 interfaces, which means I no longer needed a base thread in the setup. But the speed servo was hunting badly enough to keep the back gears in the headstock rattling pretty good when the servo thread was running at nominally 1 kilohertz. I had to reduce the P in the pid to the point it was essentially worthless at sub 300 rev speeds. So for SG, thinking the control was too slow, I did a rockhopper diagram and re-arranged the hal file so that I was doing a straight fall thru of the control path so it was not wasting a period or more because it was out of order when the modules were in the wrong order. That helped but the amount of P seemed to be limited yet, so the only other way to get a faster control loop was to raise the servo thread speed. Nominally 2 kilohertz made an obvious difference, and at 4 kilohertz, it was lots quieter. So that is where it has been running at for several months now. P in the speed PID is now high enough that I can peel off a pretty good sized string of blued steel at 150 revs, or even a dimly glowing string at 500 revs, which gives a more better finish. Hello Gene! I always like to here from your experiences. From what I've been doing I got really good results but I don't recall trying to raise the speed of the servo thread to make any difference so I'll be trying tomorrow. The idea that was spinning in my head is if it will make any difference (if possible) first to close a speed loop and then feed with that the position loop all using the same encoders for the two feedbacks. Here's an example picture: http://s23.postimg.org/6xyj2q0zf/reductor.jpg That's the rotary axis, the picture is before I mounted the encoder but you can see how it works. I know It would be the best to have another encoder on the main shaft to really know the exact position but, since this is not thar critical and the worm and gear have almost none backlash we decided this setup would be ok. What I'm doing here is to sense directly on the shaft of the motor (this would give me a really accurate reading of the speed). But It would be great if this same encoder could feed also the position loop in LinuxCNC. -- *Leonardo Marsaglia*. -- Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.

It seems redundant to measure the same axis twice, with two encoders. But often that gives significantly better results than using a single encoder. Whether it is two different kinds of sensor -- gyro, accelerometer, GPS [1] http://quadcopter.wordpress.com/2010/02/08/taking-a-break/.

They used a linear encoder for position feedback and a shaft encoder on the motor for velocity feedback. (Anybody know where the descriptive page with photos, etc. on that has gone to?) Hello Jon and thanks for the link I didn't remember about it. I guess my approach of using the same encoder mounted on the shaft of the motor isn't the best solution for speed and position feedback right?.
