#emc | Logs for 2010-10-06

[00:01:07] <Paragon39> Thanks Guys sorry for the delay in replying I was on another system!
[00:03:59] <theorb> theorb is now known as theorbtwo
[01:17:33] <Howard> Can anyone assist on installing the Mesa 5i20 card under Ubuntu 8.04 LTS please ?
[01:29:47] <SWPadnos> there shouldn't be anything special you have to do. just plug in the card and it should work
[01:30:18] <SWPadnos> I don't know if you need to edit something in the ini file to use a 5i20 with the sample Mesa configs
[01:42:05] <Howard> Are you currently using the card ?
[01:42:43] <SWPadnos> not at the moment, though I have tested several Mesa cards in the past
[01:42:53] <SWPadnos> (multiple 5i20 and 5i22)
[01:43:43] <Howard> Do you remember the Kernal you were using ?
[01:44:03] <SWPadnos> no, but it was whatever the EMC2 RTAI kernel was
[01:45:48] <Howard> when I try to use: halcmd loadrt hostmot2 it throws an error and can't share memory
[01:47:05] <SWPadnos> have you tried loading the configs/hm2-servo/5i20.ini config?
[01:50:03] <Howard> No but I can try it. Is it in the Mesa package ?
[01:50:49] <SWPadnos> it's in the emc2 package
[01:51:34] <SWPadnos> you may have to install a firmware package, depending on the version of emc2 that was first installed on that computer
[01:55:44] <Howard> Just booting the computer in question. Which country are you located in ?
[01:57:33] <SWPadnos> USA
[02:05:42] <Howard> Ok, I am in Aussie North of Sydney. I have selected a 3 axis stepper and it has a error no watchdog timer found ?
[02:06:08] <SWPadnos> 3 axis stepper what?
[02:07:39] <Howard> hm2 stepper as I have the system running on a special machine and using steppers on it.
[02:07:47] <SWPadnos> ok
[02:08:13] <SWPadnos> can you paste the exact message?
[02:09:15] <Howard> I am working on two machine at the moment so I'll get it for you.
[02:09:29] <SWPadnos> ok
[02:09:57] <SWPadnos> you should run emc from a terminal (instead of the menu) and look at the messages that are printed there
[02:10:11] <SWPadnos> there may be more information in the output of dmesg
[02:11:10] <SWPadnos> and it's possible that there is a mismatch between the firmware you have and the driver version, it all depends on how emc2 was installed, whether if was upgraded (especially between versions like 2.2->2.3 or 2.3->23.4)
[02:11:33] <SWPadnos> I've got to get a little more work done then go to bed, it's getting late here
[02:12:16] <SWPadnos> good luck with it. If you have a lot of messages or other info to post, stick it on http://pastebin.ca and link to it here. someone can look at it and give suggestions
[02:14:28] <Howard> Thanks for your time maybe catch you in a day or two.
[02:25:52] <skunkworks> logger_emc: bookmark
[02:25:52] <skunkworks> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-10-06.txt
[02:32:36] <skunkworks> http://www.youtube.com/watch?v=ovxW8TKBGWU
[02:35:20] <cradek> wheeee
[02:35:47] <skunkworks> it is a start :)
[02:36:04] <cradek> stops in the right place...
[02:36:25] <cradek> is the sequencing mechanical or electronic?
[02:36:29] <skunkworks> both
[02:36:50] <skunkworks> do this until this switch - this until this switch....
[02:36:54] <cradek> ah
[02:37:31] <skunkworks> there are switches for in and out - horizontal and vertial
[02:37:34] <skunkworks> vertical
[02:38:24] <atmega> anyone ever tried DoubleCad?
[02:41:11] <skunkworks> I have not
[02:41:44] <atmega> it seems to be free, and almost non-sucky.
[02:42:15] <atmega> it doesn't seem to do a snap-to-midpoint-of-two-points though
[02:42:28] <atmega> and I couldn't figure out how to delete construction lines before it crashed.
[02:42:35] <atmega> so... maybe I'll retract the non-sucky
[03:20:50] <Howard> Hi all, Can anyone give me a hand on: hm2-stepper.hal:43: parameter or pin 'hm2_5i20.0.watchdog.timeout_ns' not found
[07:09:08] <archivist> EMC article on wikipedia lives on :)
[07:10:33] <psha> but not too active since first day :(
[07:12:11] <paragon38> I've been looking through the information with regards to the 7i43 and the issue with netmos cards. Where am I able to find supported para cards?
[07:13:16] <paragon38> Is there still an issue with the netmos paraport cards with regards to EPP?
[07:38:24] <Valen> archivist: why was it deleted again?
[07:38:44] <archivist> not deleted
[07:39:08] <archivist> the deletion process is won and the article stays
[07:44:24] <Valen> why was it even near the deletion process?
[07:46:21] <archivist> an idiot
[10:19:02] <pjm__> archivist , morning, can u remind me the place that was doing the deals on stepper motors about 18 months back?
[10:28:28] <archivist> arc euro trade
[10:31:53] <archivist> http://www.arceurotrade.co.uk/
[10:41:00] <alex_joni> whee 650Ncm steppers
[10:50:34] <pjm__> archivist ah yes thanks! thats the ond
[10:50:36] <pjm__> one
[13:00:48] <skunkworks> I did need a 1 second delay in the arm sequence so It would ignore the vertial switch the first time around. I thought I could do rising edge... but I think when the arm comes out the switch gets cycled because of arm movement. (it would not work consistantly.)
[13:01:34] <skunkworks> ( http://www.youtube.com/watch?v=ovxW8TKBGWU )
[13:07:56] <cradek> skunkworks: when faced with weirdness, don't be afraid to move proxes/switches to make the cycle more reliable - I almost fell into that trap (wanting to leave the hardware alone, even though it could easily be improved)
[13:08:37] <skunkworks> Yes - we have done a bit of that on other things/
[13:09:26] <skunkworks> I am sure there is better ladder also. (I think my ladder is a bit messy)
[13:09:50] <cradek> I know that feeling (I bet there's always a better ladder)
[13:09:59] <skunkworks> heh
[13:26:09] <Jymmm> skunkworks: how many switches are there?
[13:26:54] <skunkworks> 4 switches and 4 solinoids
[13:27:32] <Jymmm> Instead of the delay, can't you do a 2 count (or whatever it may be)?
[13:29:12] <Paragon39> Hello All: Sorry to ask again but could does anyone know of a place were one can buy pci paraport that is compatible with the 7i43?
[13:32:57] <Jymmm> http://www.koutech.com/proddetail.asp?linenumber=48
[13:34:42] <Jymmm> http://www.koutech.com/proddetail.asp?linenumber=96
[13:35:07] <Paragon39> Thanks Jymmm BTW is it still the case that netmos parport cards are still faulty with regards EPP?
[13:35:50] <Jymmm> no clue
[13:37:31] <Jymmm> http://www.newegg.com/Product/Product.aspx?Item=N82E16815104231
[13:40:27] <SWPadnos> Paragon39, yes, I believe it's a design flaw in those particular NetMos chips, so there's no way for a card manufacturer to fix it at the board level
[13:40:40] <Jymmm> skunkworks: Instead of the delay, can't you do a 2 count (or whatever it may be)?
[13:40:40] <Paragon39> http://www.mail-archive.com/emc-users@lists.sourceforge.net/msg17979.html
[13:41:22] <skunkworks> also in the archive - peter from mesa had a list of printer port cards that worked.
[13:41:33] <Jymmm> heh
[13:42:18] <skunkworks> Jymmm: I don't think so as it - because as the arm comes out - the switch may trigger a few times randomly
[13:42:33] <Jymmm> skunkworks: Ah, ok
[13:42:53] <skunkworks> hense the second delay - so it just ignores the switch until it is a good way through the rotation.
[13:43:55] <Jymmm> skunkworks: Yeah, I got that. Just wasn't sure that was the case.
[13:44:10] <SWPadnos> Paragon39, if you're going to buy a 7i43, then add another $20 for a parallel port card, you could just bite the bullet and get a 5i20 instead. they're $200 and have more I/O
[13:44:35] <Paragon39> The problem is that most of the cards available are netmos and the chipset is not usually stated. I wondering what the chipset is of the cards Jymmm mentioned above! Have they been confirmed to work with the 7i43?
[13:45:48] <Jymmm> http://www.mail-archive.com/emc-users@lists.sourceforge.net/msg17983.html
[13:46:00] <Jymmm> Not confirmed, no.
[13:46:52] <Paragon39> SWPadnos: Thats one way to go but I like the neatness of having the card remote from the computer if you get my drift + one can also go for multiple 7i43.
[13:47:27] <Jymmm> huh?
[13:47:36] <SWPadnos> only on multiple parallel ports, with multiple IEEE1284 cables, and at a cost at least as high as a 5i20 (pushing that of the 5i22, which has 4 I/O connectors)
[13:47:53] <SWPadnos> but if you have a stepper machine with no encoders or major I/O needs, it's overkill
[13:50:28] <Paragon39> True.... I need to think which way to go with this 5i20 / 7i43. This Netmos problem could end up being a major problem for the 7i43 No?
[13:50:53] <Paragon39> Especially go forward...
[13:51:15] <Paragon39> s/go/going/
[13:51:30] <Jymmm> SWPadnos: I thought the 5i20 and the 7143 difference was i/o count?
[13:51:48] <SWPadnos> PCI vs parallel port as well
[13:52:12] <SWPadnos> 5i20 is much faster at reading/writing data, so you can get faster servo loop rates
[13:53:07] <SWPadnos> the NetMos problem could be an issue, until you find out from someone what card they've successfully used (and that exact card is still on the market ...)
[13:54:27] <Paragon39> Found this ... http://cgi.ebay.co.uk/LAVA-COMPUTERS-PARALLEL-PCI-CARD-MOKO-L72-2-/270621118570?pt=UK_Computing_Computer_Components_Graphics_Video_TV_Cards_TW&hash=item3f0246906a
[13:55:32] <Jymmm> SWPadnos: I don't get it... why in the hell would anyone go with mesa card and use paraport iface when you cna have PCI and more I/O ?
[13:55:42] <SWPadnos> cost
[13:55:55] <Paragon39> 100USD vs 200USd
[13:55:57] <SWPadnos> $100ish for 7i43, $200 and up for PCI cards
[13:57:05] <Paragon39> The main reason Im after one is to speed up my stepper motors.
[13:57:36] <Jymmm> That's like tossing a 4 banger in a 5ton pickup
[13:57:53] <Paragon39> ?
[13:58:13] <pjm__> Paragon39 i've used ebay:120556403355 in the past in my pre7i43 days, worked no problem with EMC
[13:58:25] <Jymmm> If you want MORE than ones current paraport setup, why toss a crutch on the end of it?!
[13:58:53] <Jymmm> $200 is not very much more for the gried and headaches it would save.
[13:58:58] <Jymmm> grief
[13:59:38] <Jymmm> Look at all the time you're spending trying to find a para card that *should* work, when a pci card is there that will work
[14:01:49] <JT-Work> anyone have an ISA network card with a RJ45 plug?
[14:02:21] <Jymmm> JT-Work: 3Com 3C509, 16bit ISA
[14:02:28] <Paragon39> Jymmm: I agree with you whole heartedly but every penny counts for me at the moment... :-( I have nothing but time on my hands if you get my meaning ;-)
[14:02:30] <Jymmm> lifetime warranty
[14:02:42] <JT-Work> ok, sold
[14:03:06] <JT-Work> I need one for my BP 308 VMC
[14:03:08] <Jymmm> Paragon39: Sure, but it's not like it's dedicated to one thing, you can use it for other things too down the road.
[14:03:15] <Jymmm> JT-Work: how many?
[14:03:20] <JT-Work> just the one
[14:03:50] <Jymmm> JT-Work: I think these are actually RJ-45, BNC, and AUI
[14:03:58] <archivist> Paragon39, I have the same job
[14:04:06] <JT-Work> another guy hooked his 308 up to the network and mapped a drive on another computer to load files from
[14:04:20] <JT-Work> it runs DOS 6.22
[14:04:26] <Jymmm> JT-Work: got any 30PIN Simms?
[14:04:48] <Paragon39> archivist: Sorry to hear that buddy :-(
[14:05:23] <JT-Work> yea, there are 4 here on my desk that I got for my Anilam but they won't work for it
[14:05:49] <Jymmm> JT-Work: size?
[14:05:54] <JT-Work> how do I tell?
[14:06:00] <Jymmm> plug em in =)
[14:06:02] <Jymmm> lol
[14:06:14] <JT-Work> nothing to plug them into
[14:06:32] <JT-Work> they have 2 big chips and one small chip
[14:06:42] <Jymmm> and they're 30pin, not 72 pin?
[14:07:10] <JT-Work> 30 pads on each side
[14:07:20] <Jymmm> http://www.dewassoc.com/performance/memory/images/30simm.JPG
[14:07:21] <JT-Work> W2563 on one side
[14:07:41] <JT-Work> same but not as many chips
[14:07:41] <cradek> JT-Work: what network card does it currently have in it? are you sure you can change it and still have it work?
[14:07:57] <JT-Work> there is no network card in there atm
[14:08:03] <cradek> what's the os?
[14:08:19] <JT-Work> DOS 6.22
[14:08:29] <SWPadnos> I wonder what useful clients there are for DOS 6.22
[14:08:37] <Jymmm> SWPadnos: huh?
[14:08:39] <cradek> there's an ms lanman dos client but it's very huge
[14:09:00] <cradek> I still use it, but only protected mode software is usable with it loaded, since it takes up 300k or so of ram
[14:09:01] <Jymmm> I have DOS tcp/ip clients
[14:09:25] <cradek> of course it's the client only, not server/peer-to-peer
[14:09:44] <JT-Work> All I recall is he said he mapped a drive so he could load files from his windoz computer
[14:09:51] <Jymmm> Not mine, you can do peer to peer
[14:09:53] <cradek> finding an isa network card is like 1% of the work to get this going :-)
[14:10:08] <JT-Work> I kinda though so
[14:10:10] <Jymmm> I have a stack of them =)
[14:10:13] <cradek> JT-Work: so it has the lanman software on it already? where's the network card he used?
[14:10:18] <SWPadnos> 99% to go
[14:10:27] <cradek> yeah, I can find you one too (or six)
[14:10:38] <JT-Work> I'd have to look and see what software is on my BP
[14:10:40] <cradek> or ebay I'm sure
[14:10:56] <skunkworks> I think I finally threw out all my isa network cards.
[14:11:07] <JT-Work> this was another person who has a Discovery 308 like mine
[14:11:23] <JT-Work> lol I did to last year
[14:11:24] <Paragon39> Another thing I just noticed is that the 5i20 has 200k gates and the 7i43 has 400K gates.
[14:11:28] <Jymmm> Yeah, I just didn't have the heart to toss these out, especially with lifetime warranty on them =)
[14:11:32] <cradek> ncsa had an ftpd that only required a packet driver - you'd have to exit the bp software but you could transfer files that way.
[14:11:58] <skunkworks> JT-Work: I know people that could make the machine inoperable.... then you could convert it to emc...
[14:12:10] <JT-Work> LOL
[14:12:25] <cradek> hell you might do it yourself, if you mess with dos too much :-)
[14:12:37] <skunkworks> you wouldn't have to know about it....
[14:12:42] <skunkworks> ;)
[14:12:42] <JT-Work> I ended up setting up a simple wired network so a windows machine could talk to the dos machine. it was like pulling teeth to get it to run since no one remembers the dos stuff anymore but it works great for file management. The DX32 just pulls files from the windows machine and doesn't know the difference.
[14:12:52] <JT-Work> this is what he wrote
[14:13:17] <JT-Work> http://www.practicalmachinist.com/vb/bridgeport-hardinge-mills-lathes/discovery-308-a-210632/
[14:13:19] <skunkworks> JT-Work: look in the turbocnc yahoo group.
[14:13:20] <cradek> well it's definitely possible... he must have used the lanman client if it mapped a drive like that
[14:13:31] <Paragon39> cradek: Good to see you! How have you been?
[14:13:48] <skunkworks> I think I remember others doing the same thing.
[14:13:50] <Jymmm> I have the instructions right here to create a DOS lanman peer to peer that uses 20K ram
[14:14:58] <skunkworks> JT-Work: http://tech.groups.yahoo.com/group/turbocnc/files/Dos_Net/
[14:15:23] <Jymmm> JT-Work: ftp://ftp.microsoft.com/Softlib/MSLFILES/WG1049.EXE
[14:16:17] <Jymmm> It's a self extracting ZIP file
[14:16:26] <cradek> the one I use: ftp://ftp.microsoft.com/BusSys/Clients/LANMAN/
[14:16:30] <Jymmm> Microsoft Netowrk client 3.0
[14:16:51] <cradek> Paragon39: hi, doing fine
[14:17:22] <Paragon39> cradek: Good to hear that :-)
[14:17:23] <JT-Work> thanks, I have to run some errands be back in a bit
[14:20:49] <Jymmm> JT-Work: Let me know
[14:21:03] <Jymmm> Anyone else have any 30 pin simms?
[23:26:32] <ChanServ> [#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website: http://www.linuxcnc.org/, wiki at http://wiki.linuxcnc.org/"
[23:26:52] <Guest176> thanks!
[23:26:57] <SWPadnos> sure
[23:28:03] <SWPadnos> Howard, I don't know for sure that anyone is using 10.04 and Mesa hardware. I know there are several people using 8.04, but I don't know how many of them have decided to change their (working) systems to 10.04
[23:28:35] <KimK> cradek: I have noticed one bug lately. If you use the (MSG,blahblahblah) function in axis, there always seems to be one message (the first one entered?) that you can't get rid of with the (X) button. Does anyone else notice this, or is it just me?
[23:29:34] <Howard> OK, Thanks for that maybe PCW can answer that one.
