Re: [Emc-users] 2.2.7, no touch-off available after M00???

Requiring a machine to be connected to the internet to be usable is a really bad constraint IMO. In my case I *routinely* must pack in *all* my files for use in *remote* regions. With packaging systems (such as rpm's) one need only download the appropriate rpms and do rpm -i. On the other hand, network cable is cheap, and even the hardware to ship network connections modest distances (like to an outbuilding) is not that expensive. I wouldn't want to be without the network to ship G-code files around. Maybe you can help me run some cat5 10 miles to the school where I mentor, or 200miles to the range where I work. The other issue is having NAT/IP masquerading (which I don't), so getting a machine on the internet means unplugging the main machine from the internet, plugging in the cnc machine, (assuming you can relocate it, and it even has networking capability) restart the cable-modem (so it will associate with the mac of the new machine), then hope dhcp works. And of course if I haven't configured a firewall my cnc machine is wide open for the duration. I can certainly put on my network admin hat when needed, but it's very difficult to switch gears like that (for me), especially since I do it so seldom I have to hunt down procedures for all the required operations. With RPM type packages this simply is a non-issue.

Thanks for responding Jeff, Jeff Epler wrote: emc2 does use the standard package management system on ubuntu, dpkg. Within a release series, (e.g., during 2.2.x) you can upgrade with a single .deb. Going from 2.1.x to 2.2.x is more hairy, because we often require new external packages. To upgrade from 2.2.x to 2.2.7, download the relevant file linked from http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?InstallingUpdates#On_Ubuntu_without_an_internet_connection such as http://linuxcnc.org/emc2/dists/dapper/emc2.2/binary-i386/emc2_2.2.7_i386.deb for dapper or http://linuxcnc.org/hardy/dists/hardy/emc2.2/binary-i386/emc2_2.2.7_i386.deb for hardy/i386. Install with 'sudo dpkg -i'. Based on what I learned and what I was told (and reading the offline procedure) you need apt-get to figure out which dependencies you need. The rather involved procedure outlined on the wiki explains it. If you say I only need the *one* package and dpkg -i then life is good. Based on what I'm learning it would seem to not be that easy. (ie., RTAI depencies for 2.2.7) BTW, I finally managed to get it updated with a friends help who showed me how to setup temporary NAT/IP Masquerading. Feel free to improve the the wiki on this subject so that others will have better access to this information.

Thank you very much for your replies. I feel very happy each time I get replies from the users list. I also want to use this opportunity to thank everybody here because of the realities that I have sen in EMC2. It is a wonderful game. I tried my first set up and it worked like magic. I will probably get the 1000Volts scaled down to about 3V because my system gives out 3.3V. Thank you for the components. I will feedback my results to the users list. Actually I'm not new to voltages, I'm a power man, its just that I needed a thorough explanation sometimes like the responses that came did. Thank you.

Do I need an ADC converter or what is the procedure? How heavy is your heavy motor? You need to scale the 1000V down to a range that is safe for typical integrated circuits, probably either +/-10V, or 0-5V. Then you feed that scaled signal to an analog-to-digital converter. Then the digital output of the converter needs to get into the computer (the parallel port is one possible way to do that). Next you need a driver that makes the digital data available on a HAL pin. And finally, you connect the HAL pin to a pin on your PYVCP to make the meter work. To be blunt - if you have to ask this kind of question, you are not qualified to work on 1000V circuits. EMC supports a number of boards with digital-to-analog converters, since all analog servo systems need that. There are fewer analog-to-digital converters supported, but the Servo-to-Go and Vital Systems boards do provide analog inputs. Both of those boards are rather expensive. (see http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Supported_Hardware) I believe both of those boards expect +/-10V analog inputs, so you will have to do the scaling yourself. Again I remind you that this kind of voltage will KILL you or explode your circuits if you overlook ANY details. Resistors don't just have ohms values, they also have maximum power AND voltage ratings that must not be exceeded. Circuit board clearances for power circuits are much more than you'd expect - they need to avoid arcing over under transient voltages that are much higher than the nominal. A low energy high voltage transient can ionize the air and result in a high energy arcing fault.

Re: [Emc-users] two e-stop switches
Len Shelton wrote: How do I configure hal to handle two e-stop switches on two different pins? If you're looking for two inputs to stop EMC2, you can easily do that with an or component (or and if you're using negative logic). A better way to do it is to use an input as active low, and wire the two switches in series. This will allow you to physically disable the machine from one connection as well. This is the most common practice, to wire all things that can cause an e-stop in series (the e-stop chain), and feed that to the machine disabling hardware (which then optionally informs EMC2 that the machine is off and it can stop now :) ). - Steve - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] two e-stop switches
Hi Len, Never rely on a computer for EStop or limits. Your EStop and limit switches should all be part of a chain of switches that directly kill the supply. The computer should obviously be notified that an EStop has occurred but it should not be able to prevent an EStop. In the case of limits you need some way of overriding them, preferably by a pushbutton switch rather than under software control. This is a basic safety requirement and should not be ignored. Computers and software are simply not reliable enough for safety critical functions like this. If something goes wrong with the computer or EMC crashes and causes a runaway you want to be able to stop it.

Re: [Emc-users] two e-stop switches
The standard way is to wire the switches in series using the n/c contact. So I assume you have some valid reason for wanting to do it with two inputs... like your machine is so huge you need to know which switch is in the stop condition. What you need is to or the inputs using the or2 component if you use the N/O contacts. First you have to load an or2 in your hal file with: loadrt or2 Now when you look in your Show HAL Configuration screen under Pins you will see an or2 has been loaded. You will then see that your or2 has two inputs and one output. First you connect the or2 out to the line where the single e-stop was connected (if you used stepconf wizard) it will be: net estop-ext = parport.0.pin-10-in change to net estop-ext = or2.0.out You need to connect the two inputs to your physical inputs with net. Lets say you used pin 10 and 11 of the parallel port to bring your signals in... then connect the pins to the or2 in's like so: net estop1 or2.0.in0 == parport.0.pin-10-in net estop2 or2.0.in0 == parport.0.pin-11-in This has not been tested but AFAIK it is correct... The other option which would be better is to use is the and2 component and the N/C contacts. It will be similar to the above... this should get you started and now I have to write an example for the manual... John On 2 Dec 2008 at 17:01, Jack Coats wrote: e-stop would be manual switches.

[Emc-users] loadrt abs component not working
I am using the Mesa 5i20 7i33 DAC board combination to retrofit a Kasuga mill. I am controlling a VFD that takes the standard 0-10V speed reference plus start and reverse. I am currently working my way thru the problem of outputting a speed command /voltage signal that does not switch to a negative integer/value when I hit M4. I am trying to use the abs component to strip the negative value from the floating point speed command integer coming out of motion.spindle-speed-out. Below are the corresponding statements from my m5i20_io.hal file: # Set up spindle speed control loadrt abs count=1 net spindle-rpm-cmd motion.spindle-speed-out linkps abs.0.in = spindle-rpm-cmd newsig abs-spindle float linkps abs.0.out = abs-spindle linksp abs-spindle = m5i20.0.dac-03-value net SpindleOn motion.spindle-on linksp SpindleOn = m5i20.0.dac-03-enable setp m5i20.0.dac-03-gain [SPINDLE]DAC_SCALE #from 5i20ini file# setp m5i20.0.dac-03-offset 80 Looking at the Halmeter pins/signals, the abs component shows up with 3 pins but integer values that appear on the abs.0.in pin never come out on the abs.0.out pin. Zip, nada, no output. Is is as if the abs component needs a parameter or argument that I am not aware of to make it function. Is there something I am missing here? Thanks for your help.

[Emc-users] spindle speed 0-10V reference output, can't get the abs component to work...?
I am using the Mesa 5i20 7i33 DAC board combination to retrofit a Kasuga mill. I am controlling the spindle thru a VFD that takes the standard 0-10V speed reference plus start and reverse. I am currently working on the problem of outputting a speed command /voltage signal that does not switch to a negative integer/value when I hit m4. The command: m3s3000, for example works fine without the abs component loaded, but M4 will turn the integer output from motion.spindle-speed-out to a negative value, which my vfd won't respond to. I am trying to use the abs component to strip the negative value from the floating point speed command integer coming out of motion.spindle-speed-out. Below are the corresponding statements from my m5i20_io.hal file: # Set up spindle speed control loadrt abs count=1 net spindle-rpm-cmd motion.spindle-speed-out linkps abs.0.in = spindle-rpm-cmd newsig abs-spindle float linkps abs.0.out = abs-spindle linksp abs-spindle = m5i20.0.dac-03-value net SpindleOn motion.spindle-on linksp SpindleOn = m5i20.0.dac-03-enable setp m5i20.0.dac-03-gain [SPINDLE]DAC_SCALE #from 5i20ini file# setp m5i20.0.dac-03-offset 80 Looking at the Halmeter pins/signals, the abs component shows up with 3 pins but integer values that appear on the abs.0.in pin never come out on the abs.0.out pin.

[Emc-users] Surface Finsishing
What do you guys use as the quickest and best cost effective and time-effective way to finish flat surfaces before the parts are Anodized? The parts are 8x6x3 Al boxes made from square tube with a few slots and holes CNC'd in so the surfaces are still the raw surfaces. I can CNC the boxes with a flat-face-mill , but wonder if there isnt something else you know of that is maybe a bit faster as I need to clamp and turn each side for the mill if I want to do it that way. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
