Re: [Emc-users] latency test results help with interpretation
Hi Eric, I had the same devastating experience with an 1 GHz board. After some bothersome searching for the cause of extremely large latency values (above 7) I decided to get an old ASUS P3B-F board with a Pentium III, 350 MHz processor from the attic. With the same setup, same hard diks etc. I have now 9000 at maximum of all values and threads, averaging at ca. 7000. Then I pushed it up to 500 MHz without change in results. I think Intel was compromizing when trying to boost GHz performance on the cost of real time behaviour which the average user doesn't notice while playing games. I don't see any problem with using an elderly computer as long as real time performance is good.

[Emc-users] Telnet Interface questions
Hi, I have been working on a Ethernet based pendant/operator console for EMC for a little while now (whenever I get a spare moment) , and have run into a little problem. I am using the EMCRSH, Telnet interface to EMC. My pendant was going to be quite a simple affair, but as things go, it has grown larger that first anticipated. I now have up to 84 inputs, being pushbuttons, rotary switches and encoders, and LED indicators for all of these inputs. I also have a 8 digital photo frame as a monitor. These are all controlled by a microprocessor, which is also handling the Ethernet connection to my mini-itx EMC computer. The problem I am having is when I get an error from EMC, I can't get the error message back to my pendant. I have tried the Get Operator_display, Get Operator_text and Get error commands, but none of these are returning an error to me. I am testing this by issuing a simple G01 command from MDI mode, this should invoke an error in regard to having no federate. I get an error displayed on my EMC computer, but all my status reporting to my micro are returning OK's. Is there some other command I should be using???

Re: [Emc-users] Telnet Interface questions
Hi Andrew, The problem is that the messages are deleted once they have been read. In most cases the GUI will get the messages because it is polling them quite frequently. By the time emcrsh gets there they have been swallowed by the gui. Unfortunately to change this would require a major redesign of emc's messaging system.

Re: [Emc-users] Telnet Interface questions
I don't have any suggestions - the code guys are better in that regard - butI do have a question - is your pendant project a commercial venture or an open source that you'll publish somewhere? I'm interested in what you're doing. Making my own intelligent pendant would be appealing (ok, pretty damn cool too - especially if I involve my dad for some help implementing touch panel tech from a previous job as opposed to buttons). At the very least let us know how your project turns out when it gets to where it's going.

You can't actually run this without hardware, the driver will not detect the board and will terminate. Jon, If you start with a blank slate your Universal PWM is a good cost effective solution that simplifies hardware and software setup and provides for Opto22 relays. In my case though I already have a Mesa card (won at Cardinal raffle), 50 pin breakout panels and I installed solid state relays for spindle, coolant and brake when I converted the machine to Mach3/Gecko's. The machine also has a safe, hardware based E-stop circuit. In theory all I need to do to upgrade to your AMP's is to figure out how to wire your PWM AMP's and existing encoders to the Mesa, configure the PWM Hostmot2 parameters and pass the machine's drive enable signal from the mill's E-Stop circuit back to EMC.

I only recently started using it, and it works just as outlined here: http://www.linuxcnc.org/docview/html//hal_basic_hal.html#r1_1_4 I have to second Tom's comment. As a newbie to EMC you look at other files and they use linksp all thou the file but the manual never gives a explanation of linksp. If you search thru the manual it uses linksp several times in examples. So it kind of like stepping into a mud puddle the more you move around the muddier the puddle gets. The link above is for the new commands the fact there are new commands and still working old commands that are not explain added to the mud. If you look in section 5.4.3 of the hal manual it list command that can be use in hal but does not list net. I think adding a section to the link above that shows old but still useable commands would be helpful. Then add the whole thing to the hal manual would great.

Re: [Emc-users] 5i20/7i43 Pico's PWM Amps
Roger wrote: Jon, If you start with a blank slate your Universal PWM is a good cost effective solution that simplifies hardware and software setup and provides for Opto22 relays. In my case though I already have a Mesa card (won at Cardinal raffle), 50 pin breakout panels and I installed solid state relays for spindle, coolant and brake when I converted the machine to Mach3/Gecko's. The machine also has a safe, hardware based E-stop circuit. In theory all I need to do to upgrade to your AMP's is to figure out how to wire your PWM AMP's and existing encoders to the Mesa, configure the PWM Hostmot2 parameters and pass the machine's drive enable signal from the mill's E-Stop circuit back to EMC. OK, this shouldn't be a big deal. The servo amps have optocouplers that can be put in series in the E-stop chain, so that any amp that faults will cause an e-stop. The amps run off a +12 V logic supply that needs to have its minus terminal common to the motor power supply. You need to supply +12 V to the enable terminal to enable the amps, such as with an out-of-estop SSR. The PWM and direction inputs are opto-isolated and can be run from a 5 V logic output. No current in the PWM otpo = no current to the motor. The amps are designed for a 50 KHz PWM signal, but could run at lower frequency of needed. That's all there is to it. Oh, yeah, there's one more detail. The DC (brush) version of these amps needs one short pulse in each direction after enabling, to reset the shutdown logic in the FET driver chips. The AC (brushless) amp does this internally. There is a bootstrap HAL pin in my driver to do this, I'm not sure if the Mesa driver has a similar function.

[Emc-users] FW: Telnet Interface questions
Hi Guys, Thanks for the replies, I will give the changes a try and see where I get to - I will probably have to bug you more as I get deeper into the bowels of the beast. Greg, I probably will release everything open source, as EMC is a great piece of software and I would like to contribute where I can. The micro I am using is the parallax Propeller chip, which is about as secure as a soggy paper bag, so if someone really wanted my code they could get it anyhow. At the moment it is far from complete, it will be a couple of months before I would be happy to release this. Also as a side note, I have a Windows GUI done in C# for EMC, once again using the telnet interface. I will release this also as open source, unfortunately this will have to be in a cut down version, as I wrote this for a commercial application for a customer, it is quite cool, and I am quite proud of it, in that It has adapters (software) and you can choose the motion controller you are using, at the moment this supports the dreaded ncPod, Mach3 through the its COM object and now EMC. It is totally remotable, in that you could have a screen with the estop button on it in the US, and I could have the cycle start button here in Australia and the machine could be in Timbuktu. (Not sure why you would do this, but you could if your little heart desired). The EMC side of this needs to be finished off, as it is suffering from the same error message reporting problems.

If not, then you need to figure out where the voltage was coming from. I'd generally expect an Excellon motor to de-excite the rotor very quickly when switched to open-circuit. I guess when the VFD is still decelerating the motor, it keeps the rotor magnetized, though. You should also know the VFD is not isolated from the mains, and runs on 340 V DC, so you should always treat anything connected to the VFD with great respect, even when it is stopped. The Excellon drive may have had one motor pole grounded, and that may be tied to frame ground. Certainly not a great scheme, but they all seem to use 3-wire cables. I know my motor is completely floating, but that doesn't necessarily apply to any other unit. Jon -- Check out the new SourceForge.net Marketplace.

Hi Guys, Just a quick update. I did as paul_c suggested and removed the queue type from the *.nml file. This seems to have fixed my issue, and I now seem to have error reporting coming back into my micro. I can see where Alex is coming from and understand the possible problems of doing this. I will try the changes to shcom.cc and let you know how that goes - I am a complete Linux noob so I am a little worried about doing a recompile, but I will give it a try and see how I go.

[Emc-users] request to EricJ and his new latency test results
Dear EricJ: I see you have just added two excellent latency test results to the Wiki, one for the Jetway J7F2WE1G5D (a VIA C7 CPU) and one for the Intel D945GCLF2 (an Atom CPU), with both showing less than 1ns jitter in the fast thread. Thanks very much for posting these data but could you please be a bit more explicit... It is my understanding that the Jetway motherboard has no onboard parallel port. What add-on parallel port card did you use in the test you report? Similarly, the Intel motherboard does have an onboard parallel port. Did you use it or did you use an add-on card (and if so, which one) in the test you report? Thanks in advance. Regards, Kent -- Check out the new SourceForge.net Marketplace.

I tip my hat to you for the nice work you've been doing, Andrew. Sweet. This last bit of your message, however, brings home how important it is that we all practice safe connections (ala safe sex). It's chilling to think of a hacker turning on a real machine. It seems to me one can never be too paranoid with any machinery that (1) can cause physical damage or personal injury, (2) allows for the possibility of remote control and (3) connects to the Internet so any scumbag can try his hand at it. I'm not suggesting you personally don't know the drill, Andrew, but a number of messages on this list suggest that some of our users are Unix/Linux neophytes. Please, people, please be sure your systems are locked down. There are plenty of books and websites providing chapter and verse about good system security practices. Read...understand...implement...maintain. I know I sound like a dotty maiden aunt about this, but from almost the moment my former place of employment went online we saw frequent break-in attempts by people who were obviously trying just because they could---there certainly wasn't any pot of gold lying in wait behind the firewall. If you think our EMC2 work is too arcane for black-hat hackers to bother with, just remember we're posted all over the net (this list, the Wiki, SourceForge, YouTube, CNCZone, etc.) so there are plenty of interesting hints of potential targets for those who are so inclined.

Re: [Emc-users] request to EricJ and his new latency test results
Kent, You are correct about the Jetway board, it does not have a build in parallel port. However on the systems I used that board, I was also using the Mesa 5i20 controller with the hostmot2 drivers. So no parallel port was required. The pins to run out a parallel port are provided on the board however. See Page 7: http://resources.mini-box.com/online/MBD-J-J7F2WE1G5D/MBD-J-J7F2WE1G5D-manua l.pdf A parallel port connector would have to be separately acquired however, as it is not provided with the kit. With the Intel board I am using the Mesa 7i43 which uses the parallel port for communications, not direct stepper control. All of the systems I have done either used servos or micro-steppers and thus required add on boards of some sort.
