Re: [Emc-users] unshielded cable
When it comes to shielding and noise prevention you can't have too much. Noise problems can be very difficult to track down. If would recommend screened cable but if you use unscreened, make sure everything else is really thoroughly screened. Also common mode chokes on the motor cables help a lot. Buy some large ferrite rings and wrap the drive output cables around them (without the screen). For steppers you will need two rings per drive. For each coil output , wrap both wires evenly round the ring, as close to the drive as possible. For DC servos you only need one ring per drive. These chokes smooth out some of the very high speed switching transients which are a major cause of electrical noise. I would also second the recommendation of starquad cable. It is great for small steppers and signal lines. It is also extremely flexible so it can be used in flexible cable trays. The only disadvantage is that the cores are usually not very well color coded. Les > Douglas Pollard wrote: > >> I bought some cable to run stepper motors off of. I was told it was >> shielded.

Using the cable I mentioned, with the computer, stepper psu, and xylotex driver box all on a shelf about 2 feet wide, located at ceiling height in my little shed. I've had zero problems of that sort. That means the data cable from the PC's parport to the xylotex is only about 2 feet long, and it comes into the xylotex box on the opposite side from the output cables to the motors. I ran a piece of 12 gauge all around the xylotex board, connected to the data cables ground breakout, the psu's negative terminal, and to all the ground drain wires in the Star-Quad cables to the motors. I use a PMDX-106 running on a big wall wart to interface with the spindle motors controller, and all of that is jumpered via soldered joints back to this same piece of 12 gauge. There is no shielding on the spindle motor cabling, in fact I have an ammeter on 24" extension leads in series with the return wire right at the motor, and just made a run of 10 cartridge holding blocks (I'm also a handloader), 144 holes 1/2" each, or 112 5/8" holes, drilled most of the way through a piece of cleaned up 2x6 a foot or so long. The only gotcha was the bit got stuck and the z axis couldn't lift it to clear the chips. So the x axis pulled the top of one hole sideways about 50 thou. Out of well over 1000 holes. :) That and Porter Cables forstner style bits are dull as can be right out of the package, I cut spindle current by half just by sharpening it better. I did play with the peck increments, and probably should have used more cycles, but I wound up drilling half depth, clearing chips, then to 85%, clear chips, and a final push to 100% depth, in 3 cycles, in each case I could see the last 2% driving up the spindle current cuz the bit was stuffed full. >Just last week I had some problems when I used an unshielded cable >directly connected to my Mesa 5i20 board to the E-stop.

This I would do, if I ever have the problem. I have also probed for contour several times and have not had any errors of more than a thou or two in the data. This using the sliding tube opto-interrupter device one of the guys here gave me a link to when I asked about that a couple of years ago. Home- made of course. :) To repeat, all grounds are done in 'star' fashion with the motor drivers being at the center of the star, and no cable shielding connected except at the star. All machine grounds are through the 3rd pin, and all power on the same circuit to prevent lightning surges from being anything but 'longitudinal', meaning the whole system bounces in unison so there is not a surge because one part is plugged into wall circuit A, and the rest of it is plugged in on wall socket B which may be on the opposite leg of my 240 volt shop feed. When its all on one circuit, the whole thing can bounce 100KV measured from ground, but there isn't an inter unit surge since its all bouncing the same way, microsecond by microsecond. When dealing with multiple horsepower stuff, this isn't near as easy, and makes isolation transformers a lot more desirable.

Good work! That is the only way to prevent problems in grounding. For those who don't have a background in electrics/electronics: always ground cables on one side only. Grounding cables on both sides will introduce ground loops that act as coils - this may result in a bigger problem than the original one :-} Regards, Rob -- Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.

Parameter as in .var file or with g-code #? I did a little more research, I think iocontrol.0.tool-number and iocontrol.0.tool-prep-number will work. Using a sim config and Hal Meter, it looks like tool-prep-number changes on the completion of the Tx word, and the tool-number changes on the completion of the M6 word. I suspect they where designed to work that way :). So tool prepare-prepared can stay tied together (logical short circuit). Then the change-changed loop could be opened to insert a script that checks iocontrol.0.tool-number, checks the carousel encoder and insures they match, invoke a tool removal, read iocontrol.0.tool-prep-number, move the carousel to the prep-number, move the tool from the carousel to the spindle, set tool-changed to true. Other parts of the script could be made to clean the tool taper, verify the tool is seated properly, verify the changer arm is in the proper positions, time-out if any procedure takes too long, check for adequate air pressure if needed, check for proper sensor operation, etc. One problem might be that EMC2 seems to start with iocontrol.0.tool-number = 0, and iocontrol.0.tool-prep-number = -1, so an init script may be needed to read the carousel encoder, or maybe better, require the operator to check or set the carousel, spindle and tool status at start up. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA -- Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.

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.

[Emc-users] user interface development?
Is there any documentation available on user interface development for EMC2? I have looked through the various manuals and the code for axis, Tkemc, mini and keystick all of which give me some idea as to the system calls to EMC2 for the various interfaces. Is there a complete list of the calls used to control EMC2 from the user interface available?

Re: [Emc-users] user interface development?
John, There are two main functions which a user interface must perform. 1> Issue NML commands. The best reference for these is in the Developers Handbook: http://www.linuxcnc.org/docs/devel/EMC2_Developer_Manual.pdf See chapter II on NML messages. You can also see examples of how these commands are issued in (among other places) emc/usr_intf/shcom.cc. 2> Display operational information Most operational information can be accessed through the global variable (from emc.hh) "emcStatus". It contains a number of classes including "task", "io", and "motion" which in turn have additional classes, methods, etc. to access various information including estop state, machine state, position information, etc. You can look at emc/usr_intf/emcsh.cc or emc/usr_intf/emcrsh.cc to see how emcStatus is used. You can also look at emc/nml_intf/emc.cc/hh and emc/nml_intf/emc_nml.hh for the available classes and methods. The function of the module "emcsh" is to provide an interface to EMC for tk/tcl for use with the "tkemc" user interface found in the tcl folder at the same level as src. I believe emc/usr_intf/axis/extensions/emcmodule.cc does basically the same thing for Python and the Axis user interface. If you are writing your user interface in a language other than C/C++ you will probably need some code of this sort to interface with the intended environment. One alternative, provided it has all of the functionality you require is to use emcrsh. This uses a socket connetion to interface with EMC, so is both language independent and has the ability to run the user interface either locally or remotely without running an X shell or other similar technique on the remote machine. To test it, just edit the configuration file core_sim.hal and add the line: loadusr emcrsh Then run the TkEMC configuration under "sim". You should now be able to connect to EMC as follows from a terminal session: telnet localhost 5007 When it connects, simply type "help" to get a list of available commands. For implementing a user interface, you just need to have your program issue and parse these commands the same way they are issued over the telnet session. Complete doc on emcrsh can be found here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Emcrsh Regards, Eric Is there any documentation available on user interface development for EMC2? I have looked through the various manuals and the code for axis, Tkemc, mini and keystick all of which give me some idea as to the system calls to EMC2 for the various interfaces.

I cut a pair of windows in the outside 1/4" tube such that a one piece opto interrupter (ir led on one side, ir photo-transistor looking at the led across the air gap) fit by friction across the slots. Then in the smaller tube I cut a longer pair of matching windows in, using diamond wheels in a dremel cuz that stuff bends easily, too easily to saw, filled the top with solder so a ball point pen spring could rest on it pushing it down, made a steel pointed plugin for the bottom of it, and slid a piece of a black cable tie inside it to act as the light valve. The outside tube is swaged in at the top just enough to trap the ball point pen spring. It isn't at all fancy, and if the surface its touching is slanted and slick enough for the steel point to slide down the slant, then of course there is a few thou of slop and it will record, using the G38 scan facility, a point a couple of thou lower. It worked well enough to trace the floor plate in 3d for my old deer rifle. I had visions of replacing 3oz of steel with an ounce of alu, but it is still a "work in progress". Shoemakers kids etc. :) If that link is down, perhaps I could go take some pix and put them on my web page, but mine isn't quite as well finished as that one was. Or maybe that link could be made to work again. Humm, isn't it on the wiki now, seems like I saw it there back up the log a year or ?? As far as subtracting the movement between the tip touching and the opto signal coming in, that is a fixed offset, zeroed out if you like by making contact and trigger at the top of the part, and clicking on home axis. No more offset. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

You can just save the tool number in the spindle, and reload that after a restart. For a more complex toolchanger (like Robert asked for) you also need to remember the carusel number that's currently in the tool-change position. That number is probably also in the status struct, but I'm not sure it's the best place to remember it. The whole tool changing part needs some rework, as it's designed to be specific for a certain type of tool-changer. (e.g. a rack toolchanger won't work).
