[00:19:58] <r00t4rd3d> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Keyboard_Shortcuts
[00:20:05] <r00t4rd3d> i think that is what you desire?
[00:21:38] <archivist> I think he wants us to give him a filename.pdf
[00:36:16] <ktchk> r00t4rd3d: thanks but the list is only part of the list. If the quick reference is on the screen I can print the screen but not able to change the charector size
[00:38:15] <ktchk> r00t4rd3d: I can reedit the link you supplied and can make a big print with bigger key charector . Better view in distance.
[03:14:50] <Loetmichel> mornin'
[03:19:26] <Loetmichel> sooo, two hrs quality check from customer done, no we have to shrinkwrap 18 pallets of computers and wait for the truck... and then the next order, so we dont get lazy... but this one has a bit more time in int, hopefully now overtime ;-)
[03:20:14] <Loetmichel> -w
[03:27:51] <DJ9DJ> moin
[03:31:14] <micges> moin
[09:09:51] <jthornton> Tom_itx, do you want more glade fun?
[10:03:33] <JT-Shop> Tom_itx: when I restart networking I get postconf: fatal: open /etc/postfix./main.cf: No such file or directory
[12:16:26] <IchGuckLive> hi all
[12:25:20] <FinboySlick> JT-Shop: I wouldn't worry about it unless you're running a mail server.
[12:29:03] <Tom_itx> JT-Shop i'm not sure what that is. i got it too this time
[12:29:47] <Tom_itx> i was also having issues with the static ip in interfaces
[12:30:01] <Tom_itx> it's an 'ubuntu' thing i believe
[12:32:23] <r00t4rd3d> sudo apt-get install postfix
[12:34:30] <FinboySlick> r00t4rd3d: I'm not sure he actually *wants* to run postfix.
[12:35:06] <alex4nder> yah, who wants to run postfix?
[12:35:27] <FinboySlick> Well, as a mail exchanger it's pretty cool.
[12:35:37] <alex4nder> exim||die
[12:36:04] * Jymmm throws the sendmail book (all three volumes) at alex4nder
[12:36:06] <FinboySlick> I prefer postfix. It's a few orders of magnitude more complicated than exim however.
[12:36:07] <r00t4rd3d> also learning postfix makes you valuable.
[12:37:13] <r00t4rd3d> become a spammer!
[12:37:45] <FinboySlick> r00t4rd3d: That's actually easier to do when you *don't* know what the hell you're doing with postfix ;)
[12:38:27] <r00t4rd3d> sending out emails from your own server is cool too.
[12:39:03] <Jymmm> Exim = more security options, but a bit painful and long winded to put up. Great if you really really really hate spam. Postfix = Can install and config it in one line of syntax.Its pretty easy. Fantastic for massive deployment or quick management.
[12:39:43] <FinboySlick> Jymmm: http://assets.diylol.com/hfs/751/c43/2da/resized/bee-beard-meme-generator-i-have-a-bee-beard-your-argument-is-invalid-f6e458.jpg
[12:40:09] <Jymmm> FinboySlick: goony goo goo
[12:40:28] <FinboySlick> Jymmm: Your wife is half bigfoot too? ;)
[12:40:44] <r00t4rd3d> you know what they say about girls with big feet
[12:40:48] <Jymmm> FinboySlick: and so are your kids!
[12:40:57] <Jymmm> FinboySlick: and your car!
[12:41:04] <FinboySlick> Jymmm: I guess the reference wasn't so obscure.
[12:41:11] <FinboySlick> Makes me feel old though.
[12:41:12] <Jymmm> FinboySlick: =)
[12:41:42] <Jymmm> FinboySlick: You are the 2nd person that I have ever heard that knew wth that was =)
[12:42:15] <Jymmm> FinboySlick: funny thing, NOBODY, and I mean NOBODY ever questions wth it is either! lol
[12:42:53] <FinboySlick> Jymmm: It's an awesome show.
[12:43:17] <FinboySlick> Jymmm: In a couple decades, we'll likely do the same with Louie CK material.
[12:43:22] <Jymmm> FinboySlick: Yeah, funny when he drops the mic too.
[13:16:15] <JT-Shop> I couldn't get the static ip to work either
[13:17:06] <IchGuckLive> uploading new tutorial on heekscadCNC
[13:17:06] <IchGuckLive> attach a stl to get detailed milling
[13:18:29] <JT-Shop> would this be a faster way to install the components sudo apt-get install lamp-server^
[13:18:33] <IchGuckLive> static on homeserver
[13:19:18] <JT-Shop> yea
[13:23:31] <data34876> hi
[13:23:51] <data34876> can anyone help me with build and header files for kernel
[13:23:58] <JT-Shop> http://localhost/ works
[13:24:18] <IchGuckLive> data go to the ubiuntu channel
[13:24:36] <data34876> ok
[13:24:47] <data34876> thanx
[13:24:50] <cradek> data34876: I think headers for your running kernel are always linux-headers-`uname -r`
[13:25:10] <data34876> and what are build files for kernel
[13:25:29] <cradek> need more details
[13:25:55] <cradek> what are you trying to do?
[13:25:59] <data34876> am installing vmwareplayer on my backtrack linux
[13:26:15] <tjb1> jdh: cam follower roller was broken
[13:26:21] <data34876> am getting error that build and header files for your kernel are not installed
[13:26:57] <cradek> ok, now I agree you're asking in the wrong place, but installing linux-headers might fix it
[13:27:26] <data34876> when i type apt-get install linux-headers-2.6.38
[13:27:31] <Jymmm> JT-Shop: You dont happen to have any 10-15 mil SS shim stock laying around do you?
[13:27:45] <data34876> it says the headers are already at newest version
[13:27:49] <JT-Shop> no ss shim stock at all
[13:27:55] <jdh> tjb1: replaceable?
[13:28:03] <cradek> you may need to ask vmware support for help then
[13:28:28] <cradek> this channel is for linuxcnc, the machine tool control software
[13:28:28] <Jymmm> JT-Shop: Ok, thanks. Seems nobody does, I only have aluminum and 2mil SS shim stock.
[13:28:32] <tjb1> jdh: Yep, $22 part. The plastic roller broke off of it and allowed the throttle butterfly to close another 1/8"
[13:28:52] <data34876> ok
[13:29:03] <JT-Shop> php works...
[13:29:21] <Jymmm> JT-Shop: ...most of the time.
[13:29:54] <JT-Shop> just testing my lamp and trying to get my home server up and going from Tom_itx instructions
[13:30:14] <Jymmm> JT-Shop: Oh, heh. you mean is operational. gotcha =)
[13:30:45] <JT-Shop> following this atm http://www.howtogeek.com/howto/42480/how-to-turn-your-home-ubuntu-pc-into-a-lamp-web-server/
[13:31:20] <Jymmm> JT-Shop: I thought you were talking about the quirks in php, such as: 0 == FALSE, but 0 !== FALSE. Some functions, such as strpos(), can return 0 as a valid result. For these, you must explicitly check === (or !==) FALSE.
[13:31:50] <JT-Shop> nope, trying to set up a home server thingy
[13:32:18] <tjb1> jdh: I would like to find the guy who decided where the carb bolts went….had to custom make a wrench for it
[13:32:36] <IchGuckLive> http://www.youtube.com/watch?v=A3m5Liw8LVY DONE upload STL Mill
[13:32:45] <JT-Shop> Jymmm: and this http://tom-itx.dyndns.org:81/~webpage/cnc/JT-Shop/personal_webserver.txt
[13:32:46] <Jymmm> JT-Shop: In php, '==' operator compares values, but '===' compares values AND types.
[13:33:49] <IchGuckLive> so many 3020 from china are sold now to the USA
[13:34:02] <Jymmm> 8020?
[13:34:13] <IchGuckLive> cnc router
[13:34:18] <Jymmm> ah
[13:35:25] <jdh> tjb1: I had a similar part break on my 200hp johnson. I stuck a piece of a BIC pen on it and ran it for years.
[13:35:34] <IchGuckLive> http://stores.ebay.de/Chinamedshop88-online/_i.html?_nkw=3020&submit=Finden&_sid=782672685
[13:36:40] <IchGuckLive> see the shipping it double's the price
[13:37:43] <jdh> tjb1: the red part in here: http://www.artichoke.org/boat/boat010.jpg
[13:37:46] <tjb1> jdh: This thing was about a 1/2" in diameter, dont know why they just didnt make the whole thing one piece but instead put another piece of plastic on it
[13:39:26] <tjb1> jdh: 11-12-13 here - http://www.marineengine.com/parts/evinrude-johnson-parts-diagrams/JOHNSON/47292.gif
[13:39:26] <IchGuckLive> by for today
[13:39:56] <tjb1> jdh: http://www.marineengine.com/parts/images/hg/omc/0396236.jpg
[13:40:36] <jdh> all that is plastic? (other than the roller)
[13:41:34] <Jymmm> SWPadnos: I know this is 'post mortem', but... http://www.rei.com/product/799003/steripen-adventurer-opti-water-purifier
[13:43:31] <tjb1> All of it is plastic
[13:43:35] <tjb1> The roller is just clear palstic
[13:43:37] <tjb1> *plastic
[13:43:56] <tjb1> I dont understand why it is 2 pieces to begin with...
[13:44:03] <Jymmm> tjb1: "Yo momma is plastic!"
[13:44:09] <jdh> did I mention that I love my four-strokes :)
[13:44:18] <tjb1> Jymmm: Not as much as yo momma!
[13:44:20] <Jymmm> jdh: thats what she said
[13:44:32] <tjb1> It still shakes and sputters some but I think thats because its a 2 stroke
[13:44:44] <jdh> and smokes and stinks
[13:44:47] <tjb1> Saturday will tell whether the damn thing is working right
[13:45:01] <Jymmm> which one do you have to mix oil in the fuel?
[13:45:04] <jdh> changed he impeller and lower unit lube?
[13:45:27] <jdh> Jymm: stinky smelly coughy loud 2-strokes
[13:45:38] <Jymmm> ah
[13:45:39] <Jymmm> ty jdh
[13:46:09] <jdh> http://www.artichoke.org/boat/cat1.jpg ( my current boat, a few years ago when I first got it)
[13:46:40] <tjb1> Yes, impeller was done 3 weeks ago, lower lube looks good
[13:47:04] <tjb1> I spun the motor by hand and it pumped fuel out so I didnt play with that today
[13:47:15] <Jymmm> tjb1: that pic you showed looks like glass impregnated nylon
[13:47:29] <jdh> I wouldn't screw with it.
[13:47:32] <tjb1> Jymmm: The one that broke had turned orange and basically fell apart
[13:47:35] <Jymmm> it's usually good stuff overall
[13:47:37] <jdh> I would try flushing out the carbs though
[13:48:08] <Jymmm> tjb1: turned orange? Sound liek there were no UV inhibters added
[13:48:19] <jdh> it sees no UV
[13:48:20] <tjb1> I took the carb off jdh
[13:48:32] <tjb1> Clean, needle valve was working fine also
[13:48:46] <Jymmm> jdh: Doesn't matter, they add a durability to polymers overall
[13:48:55] <jdh> what kind of boat?
[13:49:41] <tjb1> 20' pontoon
[13:50:34] <jdh> that's not a lot of motor for that.
[13:51:00] <tjb1> Not telling me anything new
[13:51:15] <tjb1> Me and my dad wanted to put a 50 mercury on it
[13:53:25] <JT-Shop> how do you tell if your isp blocks port 80?
[13:53:46] <Tom_itx> it won't work
[13:53:49] <Tom_itx> i asked mine
[13:54:08] <JT-Shop> ok so just change it to 81 then
[13:54:11] <Tom_itx> also i looked on the ubuntu site about the static ip and can't figure out why it won't work
[13:54:30] <Tom_itx> if you restart networking it will take effect but on a reboot it reverts to the dynamic one
[13:54:39] <Tom_itx> 81 82
[13:54:45] <Tom_itx> there are several ppl can use
[13:55:52] <jdh> for 'several' being many thousands.
[13:57:08] <Tom_itx> not all are for http though
[13:57:10] <Tom_itx> i have the list
[13:57:21] <jdh> the list!
[13:57:28] <Tom_itx> yes there is a list
[13:57:33] <jdh> heh
[13:57:36] <Connor> What are you talking about?
[13:57:42] <jdh> craque
[13:57:46] <Tom_itx> some are actually privately owned
[13:58:13] <jdh> you can run http on any port you want.
[13:58:16] <Connor> No ISP is going to block port 80. Port 80 is www
[13:58:23] <jdh> Connor: incoming 80
[13:58:52] <Tom_itx> Connor you don't know what you're talking about
[13:58:56] <JT-Shop> when I do step 10 I get could not reliably determine the servers fully qualified domain name using 127.0.1.1 for ServerName
[13:58:57] <Connor> I would find a new ISP if they blocked any port other than outgoing port 25 (except to their own mail servers)
[13:59:18] <Connor> Tom_itx: I was a Systems Administrator for a ISP for over 13 years.
[14:00:27] <archivist> Connor, they are talking serving from home
[14:00:45] <Connor> port 80 for home use is often used on the modem/router.. but lots of times that port can be re-assigned and port 80 opened up for use on machine behind it.
[14:01:00] <Connor> archivist: I know. and as I said, I would find a new ISP if they blocked port 80.
[14:01:37] <jdh> most people don't have a lot of choice for non-craptastic ISP
[14:02:32] <JT-Shop> now it won't connect to the router
[14:02:41] <archivist> with the lack of ip addresses fixed ip for serving is getting a cost plus option
[14:02:43] <Connor> Most is either DSL or Cable.. if your lucky you might have 2 cable company's to choose from.
[14:02:47] <Tom_itx> http://ww2.cox.com/residential/kansas/support/internet/article.cox?articleId={cacf82f0-6407-11df-ccef-000000000000}
[14:03:12] <Connor> Tom_itx: I wouldn't use COX. They're dicks. :)
[14:03:29] <Tom_itx> the alternate is much slower
[14:04:45] <Connor> That's too "big brother" for my taste. I pay for a Internet connection. Not a filtered watered down version of it. :)
[14:04:48] <Connor> Just saying.. :)
[14:05:30] <jdh> my uplink speed is so pathetic it doesn't really matter.
[14:05:45] <Tom_itx> http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
[14:05:47] <Connor> Yea, I have like 35 down, 6 up.
[14:06:07] <jdh> I have 20 down, .9ish up
[14:06:37] <JT-Shop> when I rebooted then I could get to the router
[14:06:58] <jdh> tom_itx: cat /etc/services
[14:07:18] <JT-Shop> does the name in port forwarding mean anything?
[14:07:33] <Tom_itx> not to me
[14:07:36] <Connor> no.
[14:07:39] <jdh> depends on the router.
[14:07:48] <Connor> typically not.
[14:08:05] <Connor> What type of router ?
[14:08:08] <jdh> one of mine does forwarding for known protocols with names, but you can put in whatever you want.
[14:08:36] <JT-Shop> dlink
[14:14:10] <Connor> yea, so, port 80
[14:14:48] <JT-Shop> it gives me an error about the private port not being in the range of 1-65535
[14:15:00] <Connor> private port should be 80 also
[14:15:06] <Tom_itx> what router do you have?
[14:15:14] <Connor> http://www.dlink.com/us/en/home-solutions/connect/routers/-/media/Consumer_Products/DIR/DIR-632/Manual/DIR-632_Manual_US.ashx
[14:15:25] <JT-Shop> dlink dir-632
[14:15:52] <Connor> must be a different firmware, because they don't give a option for private port..
[14:16:03] <Connor> that's more advanced..
[14:16:08] <Connor> which is nice.
[14:16:47] * Jymmm would suggest using a public port other than the norm (80, 8080, etc) as it wil help reduce the traffic of bot port scanners)
[14:16:50] <JT-Shop> page 32 shows the virtural server screen
[14:17:05] <Connor> JT-Shop that's the page I'm looking at.
[14:17:32] <Connor> Oh. I see private now.. it's really small on my screen.. strange how they've stacked them..
[14:17:36] <JT-Shop> crappy screen capture
[14:17:37] <jdh> my dlink would only forward to the same port... piece of shit
[14:18:06] <Connor> looks like you have a inbound filter too.. you want allow all..
[14:18:18] <JT-Shop> ok how to I access my web page?
[14:18:20] <Jymmm> all what?
[14:18:37] <Tom_itx> JT-Shop is the router port set the same as your ports.conf?
[14:18:41] <Jymmm> all protocols? all traffic?
[14:19:04] <JT-Shop> tom no, I need to go back and change that or change the router to 81
[14:19:10] <Connor> Jymmm: Looking at the manual.. you could restrict IP's and such.
[14:19:12] <Tom_itx> right
[14:19:14] <JT-Shop> easier to change router
[14:19:19] <Tom_itx> or it won't be visible
[14:19:41] <JT-Shop> ok both are the same
[14:19:48] <Connor> what's your external IP ?
[14:19:50] <Tom_itx> what's the ip?
[14:20:06] <JT-Shop> external IP?
[14:20:11] <Tom_itx> the one the router uses
[14:20:26] <JT-Shop> 192.168.1.120
[14:20:28] <Connor> 184.63.140.99 ?
[14:20:36] <Tom_itx> 192 is local i think
[14:20:42] <Connor> No No. Goto whatismyip.com
[14:20:43] <JT-Shop> from your example Tom_itx
[14:20:56] <Jymmm> Connor: The issue *I* have is that once you open a port to a box, there is the possibility if the box gets comprimised that they can use the box to access everything on the LAN. thus when I hear "ALLOW ALL" it can be some scarry shit.
[14:20:59] <Tom_itx> that's to view it on your local network
[14:21:06] <Tom_itx> public needs the router's ip
[14:21:30] <Connor> Jymmm: Just going on what the manual says. you can look it over if you want.. :)
[14:21:31] <Tom_itx> 192 is private i believe
[14:21:37] <JT-Shop> Connor: yes
[14:21:50] <Jymmm> Connor: No thanks, VLANS FTW!!! =)
[14:21:58] <Tom_itx> look for a 68.xx something
[14:22:02] <Connor> okay, so. 184.63.140.99
[14:22:05] <Connor> is his IP
[14:22:26] <Connor> /whois JT-Shop
[14:22:27] <Connor> :)
[14:22:37] <Tom_itx> JT-Shop what's your user name for the webpage?
[14:22:53] <JT-Shop> webpage
[14:23:10] <Tom_itx> http://184.63.140.99:81/~webpage/
[14:23:13] <Tom_itx> try that
[14:23:23] <Jymmm> 10, 172.16-172.31, and 192.168 are private subnets IPv4
[14:23:30] <Tom_itx> it timed out here
[14:23:35] <Connor> Yea. me too.
[14:23:42] <Tom_itx> you need a index.html there
[14:23:53] <JT-Shop> give me a sec
[14:24:09] <Tom_itx> there's a default one in /usr/www
[14:24:18] <Tom_itx> you could use that if you want
[14:24:28] <Jymmm> Doesn't NEED it, usually will just show an index of files otherwise.
[14:24:56] <Connor> might want to check the access control..
[14:25:08] <Connor> If you don't have a rule for port 81.. then it won't work.
[14:26:44] <JT-Shop> yea I have on in var/www how do I use that one
[14:26:48] <Connor> add a rule, call it www, policy Alwys, type, IP, put in your PRIVATE ip of your macine,
[14:27:07] <Tom_itx> 184.63.140.99:81 shold resolve to that one
[14:27:12] <JT-Shop> where is the rule?
[14:27:16] <Tom_itx> unless your router is still blocking it
[14:27:20] <Connor> Apply Advanced Port filter rule checked.,
[14:27:25] <Tom_itx> i didn't need a rule on mine
[14:27:35] <Connor> JT-Shop: page 37
[14:27:38] <Tom_itx> i just sent the port to the ip
[14:28:00] <Connor> Tom_itx: That should be correct..but.. who knows.. some of these routers do funny things.
[14:28:21] <Tom_itx> it should be open by default unless you set a rule
[14:28:21] <JT-Shop> application rule in advanced?
[14:28:38] <Connor> Not sure.
[14:29:25] <Tom_itx> i can't ping 184.63.140.99
[14:29:44] <Tom_itx> check your router ip again
[14:30:03] <Connor> that might just mean the ISP has ping blocked..
[14:30:12] <Connor> which IS fairly common on residential
[14:30:20] <JT-Shop> private ip is the one I set in the virtual ?
[14:30:33] <Tom_itx> yes i believe so
[14:30:46] <Tom_itx> also what range does your router allow?
[14:30:51] <Tom_itx> it may be a different ip range
[14:30:58] <Tom_itx> than what i gave in the example
[14:31:11] <JT-Shop> how do I see the range
[14:31:39] <Tom_itx> under dhcp?
[14:31:42] <Jymmm> Tom_itx: many routers have a setting to not to respond to ping, aka stealth mode.
[14:32:24] <Tom_itx> JT-Shop, P.27
[14:32:34] <Tom_itx> your ip needs to be within that range
[14:32:46] <Tom_itx> or change the range
[14:33:13] <Tom_itx> i think i changed my range
[14:33:31] <JT-Shop> it's 192.168.0.100 - .199
[14:33:46] <Tom_itx> so change that or change your local static ip assignment
[14:33:55] <JT-Shop> ok
[14:33:57] <Jymmm> JT-Shop: does your sattellite block ports?
[14:33:59] <Tom_itx> so it fits in the range
[14:34:19] <JT-Shop> Jymmm: dunno
[14:34:39] <Tom_itx> we'll find out. if he can view it locally on his network and not public...
[14:34:51] <JT-Shop> ok
[14:35:04] <Tom_itx> for a local view use the 192. address
[14:35:18] <Tom_itx> 192.168.0.121:81
[14:35:20] <Tom_itx> or such
[14:35:34] <Jymmm> http://127.0.0.1:81/
[14:36:15] <JT-Shop> should I do that on the same computer or a different one on the same network
[14:36:33] <FinboySlick> JT-Shop: 127.0.0.1 is the same computer, always.
[14:36:35] <Jymmm> JT-Shop: what is your sat ISP?
[14:36:42] <JT-Shop> wildblue
[14:37:47] <JT-Shop> 127 works on the same computer and the it works! page shows up but 192.168.0.120:81 does not work
[14:40:05] <Jymmm> http://192.168.1.120:80/
[14:40:37] <Tom_itx> what did you set the port to be?
[14:41:42] <JT-Shop> 192.168.0.120
[14:41:46] <JT-Shop> :81
[14:42:05] <Jymmm> JT-Shop: your modem black or blue?
[14:42:41] <JT-Shop> black I think
[14:47:20] <Jymmm> JT-Shop: BTW, setting up a public web server is against the acceptable use policy. Item: XIV http://www.wildblue.com/legal/acceptable-use-policy
[15:11:56] <Connor> His freakign router rebooted..
[15:12:11] <jdh> I thought it might help, so I rebooted it for him.
[15:12:25] <Connor> ROFL
[15:12:31] <Connor> waiting for him to come back up..
[15:12:50] <Connor> I hope their isn't somethign else in the config he changed on it that's causing him issues.
[15:12:50] <archivist> isp will be reflashing his router to make him comply
[15:13:10] <jdh> no need, they will just block anything they don't like.
[15:13:22] <jdh> wonder how bad sat. uplink speed is?
[15:13:26] <Connor> I had it working.
[15:13:35] <Connor> His IP may have changed though..
[15:14:23] <jdh> RR almost always gives me the same ip.
[15:14:41] <Connor> I've had the same IP for like 2.5 years now.
[15:14:46] <jdh> 80/tcp open http
[15:14:56] <archivist> if my ip changes, BT has failed in its obligations :)
[15:15:03] <Connor> okay, anyone have a phone # for him ?
[15:15:07] <jdh> 81 is open also
[15:15:10] <Tom_itx> Jymmm are you the webserver police?
[15:15:19] <Connor> or way to get in touch with him..
[15:15:30] <Connor> I'm afraid he's done something to trash his router config.
[15:16:07] <jdh> it's still working on :81
[15:16:13] <Tom_itx> guess again
[15:16:30] <Connor> He's back!
[15:17:42] <Jymmm> Tom_itx: No I'm not, but I dont want jthornton's internet shut off because it's agaist the AUP either, he's had such a bitch of a time over the years even getting anything other than dialup.
[15:17:56] <Tom_itx> oh
[15:17:58] <JT-Shop> Jymmm: do you think they will care?
[15:18:20] <Tom_itx> i asked mine to unblock 80 for me and they said no. i told them i'd do what i needed to do then
[15:18:37] <Jymmm> JT-Shop: It depends on how much of a prick they are. satellite bandwidht is expenseive, they might care moreso than say dsl or cable internet.
[15:18:53] <archivist> some just charge a bit more for the privilege
[15:19:03] <Jymmm> JT-Shop: there are forums for them if you want to ask
[15:19:04] <Tom_itx> if your traffic is minimal they won't say anything i doubt
[15:19:08] <JT-Shop> their bandwidth meter is broken and they don't care if it works or not
[15:19:22] <Tom_itx> if you start getting alot more traffic they may not like it
[15:19:49] <Tom_itx> mine hasn't ever been alot
[15:20:05] <Tom_itx> you can use google analytics on your pages if you wanna monitor it
[15:20:10] <Tom_itx> or some such thing
[15:20:16] <Jymmm> JT-Shop: it's not you little traffic, it's the scammers that port scan that added extra usage that may throw soem flags (potentially)
[15:21:03] <JT-Shop> that part worries me a bit
[15:21:21] <jdh> I ran a cross an article by texasmicrocircuits.com in an old digital machinists magazine. Most badly written article ever...then I checked their web site, and it is the worst web site I've ever seen.
[15:21:31] <Jymmm> JT-Shop: I'd toss it on an oddball public port ( > 10000+)
[15:22:02] <Connor> http://184.63.140.99:81/
[15:22:03] <JT-Shop> pick a number
[15:22:05] <Jymmm> most only scan the common ports
[15:22:06] <Tom_itx> i don't think many use 81 or 82
[15:22:08] <Connor> got it working for him now.
[15:22:09] <Jymmm> 43882
[15:22:16] <Jymmm> 23953
[15:22:23] <Jymmm> 39248
[15:22:26] <Jymmm> all random
[15:22:31] <Jymmm> (I hope =)
[15:22:36] <Tom_itx> yeah that's the default /usr/www directory
[15:22:49] <Tom_itx> but it is working
[15:23:07] <Tom_itx> JT-Shop, now get a name from dyndns or such for free
[15:23:09] <JT-Shop> the default var/www is ok
[15:23:14] <Tom_itx> yeah
[15:23:19] <Tom_itx> i have multiple ones
[15:23:34] <Connor> His ubuntu was DHCP and was on .109
[15:23:40] <Jymmm> jt-is-such-a-whore.dynadns.org
[15:23:42] <Tom_itx> if you just have one that's fine and probably alot easier for ubuntu
[15:23:47] <Tom_itx> heh
[15:23:54] <Connor> we set it to reserve that IP for the machine and changed the mapping to reflect.
[15:24:08] <Tom_itx> is his static ip working now?
[15:24:18] <Connor> I don't think so.
[15:24:25] <Jymmm> JT-Shop: You can also only run it when you need it if that helps any.
[15:24:25] <Tom_itx> i need to figure out what it takes to make that work in ubuntu
[15:24:33] <Connor> I just told the router to reserve that IP for his LAMP machine.
[15:24:34] <Tom_itx> i'm using debian on my server
[15:27:25] <JT-Shop> can I switch it off on the computer somehow?
[15:27:47] <Connor> switch what off ?
[15:27:47] <Jymmm> JT-Shop: easier to just close the port on the router when not needed
[15:28:03] <JT-Shop> the web page access
[15:28:14] <Connor> Ah.. Schedule thingie in the router might be of some help.
[15:28:23] <JT-Shop> ok
[15:28:24] <Jymmm> JT-Shop: err... disbale the port forwarding on your router when not in use
[15:28:50] <Tom_itx> that would be the easiest probably
[15:28:57] <Tom_itx> or change the port in ports.conf
[15:29:00] <Jymmm> usually there's an option to enable/disable port forwarding entries without having to add/remote it.
[15:29:03] <Jymmm> remove
[15:29:23] <Connor> stop the http service.
[15:29:29] <Connor> number of ways to do it.
[15:29:51] <Connor> just depends on were your at and how you want to do it.
[15:30:24] <JT-Shop> the computer is right next to me and I don't know how I want to do it :)
[15:30:34] <Tom_itx> unplug it?
[15:30:44] <Tom_itx> that always works
[15:31:29] <JT-Shop> well I write programs for my CNC machines on this box... maybe I should use another for this now that I know how
[15:31:34] <Connor> sudo service apache2 stop
[15:31:35] <Tom_itx> JT-Shop so you're using a dynamic ip right now?
[15:31:44] <Tom_itx> no need really
[15:31:49] <JT-Shop> no, can't find out how
[15:31:58] <Connor> in the command line will shut down the webserver.
[15:32:00] <Tom_itx> i had it working once
[15:32:01] <JT-Shop> kill apache2 would work
[15:32:08] <Tom_itx> if i figure it out i'll let you know
[15:32:35] <Tom_itx> they probably changed something in one of the updates
[15:32:52] <Tom_itx> it's a bit different on debian too but debian works
[15:34:56] <Tom_itx> JT-Shop, where is gnipsel hosted?
[15:34:57] <JT-Shop> damm screen just went black again on the ubuntu computer
[15:35:10] <JT-Shop> website4life
[15:35:33] <Tom_itx> is it bandwidth limited?
[15:35:38] <JT-Shop> no
[15:35:40] <DJ9DJ> screensaver? ;)
[15:36:04] <JT-Shop> it does not recover from it
[15:36:36] <JT-Shop> I have to hold the power button in for 15 sec then press again to start
[15:40:03] <Tom_itx> what does self.error_channel() return?
[15:40:12] <Tom_itx> what does self.error_channel.poll() return?
[15:40:25] <JT-Shop> in the gui tutorial?
[15:40:53] <JT-Shop> the second one updates the error list if any
[15:58:38] <wd5jwy> I have a couple of questions for anyone out there familiar with GladeVCP
[15:58:58] * jthornton runs and hides
[15:59:51] <wd5jwy> jthornton - can I ping you in a separate chat - do you have a minute?
[16:00:24] <jthornton> yea
[16:00:52] <Tom_itx> it might be useful to us all though
[16:02:00] <jthornton> that's what I thought
[16:03:51] <Tom_itx> jthornton did you find anything left out in that file i linked you?
[16:04:42] <jthornton> not really, just the router stuff and I used lamp to install everything so faster
[16:05:30] <Tom_itx> what is lamp?
[16:05:56] <jthornton> linux apache3 mysql php
[16:06:02] <jthornton> one install does it all
[16:06:08] <Connor> Yup.
[16:06:08] <Tom_itx> oh
[16:06:38] <Tom_itx> well i'm still a rookie
[16:06:39] <jthornton> sudo apt-get install lamp-server^
[16:07:18] <Jymmm> sudo makemeasandwich
[16:11:52] <wd5jwy> So my current config.ini already has a POSTGUI_HALFILE = custom_postgui.hal statement in it
[16:12:12] <wd5jwy> do I replace that or just add another to make my custom panel work?
[16:12:13] <jthornton> are you using the custom_postgui.hal file?
[16:12:22] <wd5jwy> not that I know
[16:12:35] <jthornton> then just change the name to what you want to use
[16:12:36] <wd5jwy> I just start axis after running the stepconfig
[16:12:55] <wd5jwy> ok, so that's what I did and got the errors
[16:12:57] <jthornton> I usually just call it postgui.hal
[16:13:01] <jthornton> less typing
[16:13:15] <wd5jwy> let me do it again and I'll post the exact error I'm getting
[16:13:18] <jthornton> so you have some stuff in the other file
[16:13:27] <wd5jwy> yes, just one statement
[16:13:38] <DJ9DJ> gn8
[16:13:51] <jthornton> say goodnight Gracie
[16:13:55] <wd5jwy> setp gladevcp.hal_table1 1
[16:14:05] <wd5jwy> that's all that's in the .hal file
[16:14:23] <wd5jwy> to make the table active on startup
[16:15:40] <jthornton> comment that out and run your config
[16:16:02] <wd5jwy> ah, ok
[16:16:06] <wd5jwy> just a sec
[16:17:57] <jthornton> now look in show hal configuration for the gladevcp pin names
[16:18:19] <wd5jwy> ok, it ran that time with that statement commented out
[16:18:38] <wd5jwy> do I need to change the name of the Hal_Table1 to something else maybe
[16:19:22] <jthornton> did you look at the pins?
[16:19:31] <wd5jwy> I'm looking now
[16:19:58] <wd5jwy> OK, I see them - what am I looking for?
[16:20:48] <wd5jwy> pin name for the Hal table is Coil_Winder.hal_table1
[16:20:49] <jthornton> do you have any gladevcp pins?
[16:21:35] <wd5jwy> well, I have Pins/Coil_Winder - then all the pins listed - aren't those the GladeVCP pins?
[16:21:41] <jthornton> kinda long don't you think?
[16:21:48] <wd5jwy> yeah
[16:22:01] <wd5jwy> but, I'm just trying to get something working
[16:22:28] <jthornton> if it is under gladevcp it is
[16:22:58] <wd5jwy> well, I don't see anything that says GladeVCP
[16:23:06] <jthornton> click on the pin so it shows up in the show window
[16:23:20] <wd5jwy> Just Components Pins Parameters etc
[16:23:21] <jthornton> then you don't have it loaded
[16:23:37] <wd5jwy> hmmmm
[16:24:19] <jthornton> http://imagebin.org/224466
[16:24:36] <jthornton> click on the + in front of pins
[16:25:13] <wd5jwy> I did
[16:25:40] <wd5jwy> it expands to Coil_Winder - the name of the ui
[16:25:50] <wd5jwy> and then the pin names below it
[16:25:58] <r00t4rd3d> sweet, another shooting
[16:26:29] <jthornton> wd5jwy, this is a stepconf config?
[16:26:30] <Tom_itx> we had a local one today
[16:27:24] <wd5jwy> yeah created with the stepconfig tool
[16:28:18] <jthornton> show me a screen shot like the one I just posted
[16:28:25] <wd5jwy> http://imagebin.org/224467
[16:29:16] <jthornton> ok, you renamed it then
[16:29:33] <wd5jwy> yes
[16:30:08] <wd5jwy> so just wondering why the setp command in the .hal file doesn't work
[16:30:30] <jthornton> what was the command?
[16:31:10] <wd5jwy> # setp gladevcp.hal_table1 1
[16:31:14] <wd5jwy> oh, I see
[16:31:20] <wd5jwy> god, I'm such a dumbass
[16:31:27] <wd5jwy> so, it should be
[16:31:43] <wd5jwy> setp coil_winder.hal_table1 1
[16:31:46] <wd5jwy> geeeze
[16:32:02] <jthornton> well close you do have some humpyback
[16:32:13] <jthornton> best to change the name to all lower case
[16:32:30] <wd5jwy> ok - to avoid what exactly?
[16:32:35] <Tom_itx> problems
[16:32:45] <wd5jwy> we don't like problems
[16:32:52] <wd5jwy> will do
[16:33:19] <wd5jwy> thanks guys
[16:33:24] <wd5jwy> sorry to waste your time
[16:33:30] <wd5jwy> on something so stupid
[16:33:32] <Tom_itx> put a quarter in the jar
[16:33:37] <wd5jwy> will do
[16:33:41] <jthornton> no waste if you learned something
[16:33:52] <jthornton> and some lurker might have learned as well
[16:34:11] <wd5jwy> it's always the same with code - 1+1 does not equal 3
[16:36:47] <jthornton> now you have to work through my glade tutorial and look for mistooks
[16:37:28] <Tom_itx> zz
[16:39:03] <wd5jwy> Yes, I've been playing with that one too
[16:39:11] <wd5jwy> I do have one question on that
[16:39:16] <wd5jwy> in the python file
[16:39:29] <jthornton> I've fixed a lot today and yesterday
[16:39:32] <wd5jwy> you have a string variable that seems to never be used
[16:39:43] <wd5jwy> eval_string = ""
[16:39:46] <wd5jwy> what is that for?
[16:39:52] <wd5jwy> where is it used?
[16:39:53] <jthornton> copy and paste error
[16:39:59] <wd5jwy> ah, ok
[16:40:03] <wd5jwy> thot that might be it
[16:40:20] <wd5jwy> I learned a lot just trying to find out why that was there
[16:40:47] <jthornton> searching the web for answers on that?
[16:40:55] <wd5jwy> yes
[16:41:13] <wd5jwy> thot maybe it was inherited from some other class
[16:41:17] <jthornton> did you find the calculator tutorial?
[16:41:21] <wd5jwy> yes
[16:41:27] <wd5jwy> same variable there too
[16:41:30] <jthornton> that is where that came from I think
[16:41:48] <wd5jwy> makes sense
[16:41:55] <wd5jwy> easier to copy-n-paste
[16:42:00] <jthornton> but he used it in his code
[16:42:05] <wd5jwy> ah
[16:42:39] <wd5jwy> I thot you just created it and then never put it to use
[16:43:32] <jthornton> no, I was searching for how to calculate the RPM for my example and found the calculator one so I snipped a couple of lines from it
[16:44:14] <jthornton> I changed the status one quite a bit if you want to do it over again it makes more sense now
[16:44:22] <wd5jwy> will do
[16:44:47] <wd5jwy> I actually couldn't get it work with Hal widgets instead of the common widgets
[16:44:53] <wd5jwy> I know I was doing something wrong
[16:45:02] <wd5jwy> but, I'm not going to bug you on that
[16:45:08] <wd5jwy> I'll keep playing with it
[16:45:26] <jthornton> after doing the glade tutorial you might want to do the gui tutorial it has a mix of gladevcp in it
[16:45:47] <wd5jwy> ok
[16:46:06] <wd5jwy> so I know this is another stupid question
[16:46:29] <jthornton> you shouldn't lead the audience
[16:47:02] <wd5jwy> what is the difference between using gladevcp and creating a panel with .ui extension vs a .glade extension?
[16:48:04] <jthornton> if you use .ui and click on the file name then Qt will open it, if you use .glade then Glade3 will open it that is why I use .glade
[16:49:13] <wd5jwy> so the widget functionality is the same either way?
[16:49:30] <jthornton> yea
[16:50:37] <jthornton> I use several gladevcp widgets in my gui tutorial
[16:50:44] <jthornton> and actions
[16:51:43] <wd5jwy> yes, and when I tried Hal widgets, I couldn't get it to work - but I'll work on that til I figure out why - I'll learn something.........maybe
[16:52:31] <jthornton> I think if you do the gui tutorial it will shed some light on the gladevcp widgets for you
[16:54:11] <wd5jwy> yep, what I'm really trying to do is create a control that will allow me to precisely set the RPM on a couple of stepper motors.
[16:54:56] <wd5jwy> and maybe provide some feedback as to completed shaft rotation - turns count
[16:56:01] <wd5jwy> I wouldn't think it would be that difficult once I get a handle on the scripting - never played with Python before, so I'm new at it
[16:56:48] <JT-Shop> so your using a velocity input to the stepgen?
[16:57:19] <wd5jwy> I haven't gotten that far yet - so don't know how I'm going to do it
[16:57:24] <wd5jwy> but it must be possible
[16:58:12] <wd5jwy> the stepconf utility does it with the Test motor function - it allows you to set the motor speed with a spinbutton
[16:58:20] <wd5jwy> that's all I'm trying to do
[16:59:22] <wd5jwy> basically, I want to use a spinbutton to set the speed (RPM) on one motor and then input a ratio - the ratio would then calculate the speed (RPM) of the other motor
[17:00:16] <wd5jwy> so, I would then have one motor running at say 60 RPM while the other motor runs at 90 RPM with a ratio of 1:1.5
[17:00:19] <JT-Shop> sounds like it should work
[17:01:11] <wd5jwy> I want the input ratio to calculate and then set the speed of the other motor based on the set speed of motor number 1
[17:01:19] <wd5jwy> I'm trying to build a coil winding machine
[17:02:05] <wd5jwy> motor 1 would control the traverse mechanism by using a cam-driven shaft - the other motor (motor2) would wind the wire on the coil bobbin
[17:02:21] <JT-Shop> ah ok
[17:02:35] <JT-Shop> good to read this page http://linuxcnc.org/docs/html/man/man9/stepgen.9.html
[17:02:43] <JT-Shop> what is working so far?
[17:02:52] <wd5jwy> the actual ratio of speeds between the two motors is what is critical
[17:03:21] <wd5jwy> nothing so far - just got the stepper motors and controller working - just starting on trying to write the code to control them
[17:03:36] <wd5jwy> I've already built a hand-cranked model that works
[17:04:07] <JT-Shop> well you can turn your table on now
[17:04:30] <wd5jwy> I'm trying to duplicate how the old mechanical coil winders worked - they used numerous cams but they achieved the speed ratio through the use of gears
[17:04:54] <wd5jwy> so instead of using gears, I thought of using stepper motors instead
[17:04:58] <wd5jwy> nothing new about that
[17:05:09] <wd5jwy> but commercial winders cost well over 5 figures
[17:05:15] <wd5jwy> can't afford one of those
[17:05:17] <JT-Shop> seems to me you just need the velocity of the second motor from the ratio
[17:05:27] <wd5jwy> exactly correct
[17:05:57] <wd5jwy> so I'll have one spinbutton to set the speed for the first motor - then a text box for entering the ratio
[17:06:06] <wd5jwy> which would set the speed of the second motor
[17:06:24] <wd5jwy> then a start/stop button
[17:06:29] <JT-Shop> yep and toss in a little python math and your set
[17:06:42] <wd5jwy> maybe also some controls for acceleration as well
[17:06:54] <JT-Shop> you can do that in stepgen
[17:06:59] <wd5jwy> cool
[17:07:04] <wd5jwy> I'll look at the link
[17:32:46] <JT-Shop> Tom_itx: did you get your web server to keep the same ip?
[17:41:59] <Tom_itx> haven't messed with ubuntu anymore yet but my main one works fine
[17:42:46] <JT-Shop> we had to set the router to reserve that address so it would not reassign it during a reboot
[17:43:16] <Tom_itx> i just picked one high enough it wouldn't get assigned
[17:43:27] <JT-Shop> ah ok
[17:44:31] <Tom_itx> about half of the stuff here is wireless
[17:44:47] <Tom_itx> just got a new wireless access point for that
[17:45:15] <Tom_itx> so far it's working a helluva lot better than the linksys
[17:45:18] <JT-Shop> ah ok, I'm almost all wired Cat6e
[17:45:35] <Tom_itx> me too but there are 3 or 4 laptops etc here
[17:45:41] <Tom_itx> game consoles...
[17:46:17] <Tom_itx> i have a 24 port switch under my desk
[17:47:01] <Tom_itx> http://www.ubnt.com/unifi
[17:47:07] <Tom_itx> and one of those for wifi
[17:50:18] <JT-Shop> http://184.63.140.99:81/public/
[17:50:28] <JT-Shop> neat
[17:50:33] <L84Supper> http://www.micromanufacturing.com/content/micromanufacturing-lab-tour-northwestern-univ nice granite benches
[17:50:49] <Tom_itx> JT-Shop now go sign up at dyndns and get a name for it
[17:50:55] <JT-Shop> where?
[17:51:21] <Tom_itx> http://dyn.com/dns/
[17:52:23] <JT-Shop> those seem to be all pay for services
[17:52:43] <Tom_itx> there's a free one there somewhere... i'm looking
[17:52:55] <JT-Shop> me too
[17:53:01] <L84Supper> yeah, it's free but you have to renew every 30 days
[17:53:06] <Tom_itx> if you set your router up to ping them you don't have to keep resigning
[17:53:17] <Tom_itx> L84Supper ^^
[17:53:17] <L84Supper> it's ~$25 for a whole year
[17:57:21] <L84Supper> http://dyn.com/dns/dns-comparison/ Pro vs Standard, I've been using them for ~10 years with no real problems so far
[17:57:23] <Tom_itx> maybe they don't offer free now
[17:57:32] <Tom_itx> i still get mine free
[17:59:25] <L84Supper> yes, they used to have a free version that would expire if you didn't login every 30 days
[17:59:46] <Tom_itx> they email me now
[17:59:59] <Tom_itx> but my router used to ping them so i never used to get bothered
[18:00:50] <L84Supper> I use it for VOIP so I just paid for 5 years with some special offer
[18:01:09] <L84Supper> ~$10 a year
[18:02:17] <Tom_itx> You can cancel the trial before 14 days and still receive one free hostname
[18:03:14] <Tom_itx> If you do not have a hardware update client, you can install a software update client on a computer anywhere in the network (typically your server computer). We recommend using a software client whenever possible, since they are easier to troubleshoot and configure than hardware update clients.
[18:04:37] <Tom_itx> Linux/Unix: ddclient

[21:11:06] <ReadError> that picture = diabetus
[21:46:41] <jp_> how do you get a following error on a stepper system?
[21:50:07] <jdh> config problem. Stepping too fast
[21:53:11] <r00t4rd3d> wow i just got a weird request. A lady wants a sign for a flower girl to hold instead of flowers
[21:53:18] <jp_> but how does the controller know?
[21:53:29] <r00t4rd3d> "Last Chance To Run Cal!"
[21:53:51] <jdh> it uses the stepgen output
[21:54:04] <r00t4rd3d> parallel settings
[21:55:13] <jp_> i still fail to see why the controller would see a following error
[21:55:31] <jdh> the requested step rate can not be generated
[21:55:49] <jp_> ah ok that makes sense
[21:56:10] <jdh> I've seen it when the base period was too high for the requested speed
[21:56:10] <jp_> hardware limitation
[21:56:26] <jdh> if the values are accurate, it is a HW limit.
[21:56:56] <jp_> i get it. sorry it's my first time playing with steppers
[21:57:19] <jdh> I only know because I had the same thing happen.
[21:57:56] <jp_> so if i lower my microstep rate per rev i can go a bit faster
[21:58:03] <jdh> yep.
[21:58:26] <jdh> or decrease screw pitch, or get a box with lower latency, or get a cheap mesa card
[21:58:35] <jp_> or accelerate faster
[21:58:44] <jp_> im using mesa
[21:58:53] <jp_> 5i25 and 7i76
[21:58:55] <jdh> then it is a config issue
[21:59:36] <jp_> ill drop the drive down to 1000ppr
[22:00:05] <jdh> I doubt you are hitting a mesa HW limit.
[22:00:12] <jdh> more likely just a config prolem.
[22:00:39] <jp_> just running pncconf for right now
[22:01:21] <jdh> my pncconf config did the same
[22:02:30] <jdh> stepgen.00.maxaccel and .maxvel perhaps.
[22:02:57] <jdh> for all axes
[22:03:08] <jp_> yeah when i increased those thats when i got the error
[22:03:25] <jp_> sorry in the ini
[22:05:13] <jdh> I think even my pport driven 7i43 can do mhz stepping. the pci one should be as good or better.
[22:06:03] <Tom_itx> jt's config is likely on his site
[22:06:16] <Tom_itx> he's using a 5i25 on his plasma
[22:06:42] <Tom_itx> i'm using the 7i43 as well with good results
[22:07:33] <jp_> i use the 7i43 on my mill
[22:07:43] <jp_> no complaints
[22:10:00] <pcw_home> If you have a following error with the hardware stepgen it usually means you have fairly high jitter in the servo thread
[22:10:02] <pcw_home> the workaround is to set the stepgen maxaccel about 20% higher than the machine maxaccel
[22:10:26] <Tom_itx> http://gnipsel.com/linuxcnc/configs/index.html
[22:10:39] <jp_> jitter numbers look good on the latency test
[22:10:53] <Tom_itx> that might give you a starting point
[22:10:59] <pcw_home> the 5I25 will do up to 8.33 MHz step rates, the 7I43 12.5 MHz
[22:11:32] <pcw_home> As I pointed out lately in the emc developers list the servo thread latency test lies
[22:12:21] <pcw_home> (measured >100 usec jitter via scope latency test shows 6 usec)
[22:12:56] <jp_> default step timing doesnt help either
[22:13:53] <jp_> PCW_home:good to know thanks!
[22:13:57] <r00t4rd3d> stupid peer
[22:14:30] <pcw_home> Yes, you can also get that error if the steplen and stepspace will not allow the requested step rate
[22:16:28] <jp_> it's default is 1000 in pncconf. I didn't bother to change it
[22:17:21] <pcw_home> the hardware stepgen is actually OK with pretty high jitter but the driver part goes bad if you
[22:17:24] <pcw_home> dont limit its velocity corrections (of what it thinks is wrong due to jitter but is not actually wrong)
[22:17:54] <pcw_home> 1000 is probably too fast for a lot of drives
[22:18:29] <jdh> too fast would just miss steps, not cause the following error message?
[22:18:30] <jp_> checking thew drive specs right now
[22:19:03] <pcw_home> Yes it would likely cause missed steps (but not a following error)
[22:19:23] <jdh> guess I should have commented the change, you or andypugh told me what to change in mine to fix it (wasn't len/space though)
[22:19:55] <jp_> In pulse & direction mode, motor steps on falling edge of step input.0.25 μsec minimum pulse, 2 MHz max step rate. 1 μsec minimum setup time, 50μs minimum hold time for direction signal.
[22:20:43] <skunkworks__> pcw_home: just certain motherboard combos?
[22:21:01] <pcw_home> so far only Atom
[22:21:18] <pcw_home> (that I know of)
[22:21:20] <skunkworks__> where you able to try a external video card?
[22:21:40] <pcw_home> Not yet, maybe tommorow
[22:22:07] <jdh> I was going to buy another d525. Guess I'll wait :)
[22:23:27] <pcw_home> stepgen maxaccel set to 0 (no limit) , stepgen maxvel set with no headroom are other reasons for a stepgen following error
[22:24:24] <pcw_home> the d525 is OK just dont expect it to run servo threads faster than about 1.5 KHz
[22:27:56] <jp_> well that works much better
[22:29:35] <tjb1> Do you still use collars and thrust bearings to contain ball screws?
[22:29:54] <jp_> yep
[22:32:11] <jp_> unless you have coin to spare for angulars
[22:32:47] <tjb1> http://www.ebay.com/itm/1-anti-backlash-ballscrew-RM1605-450-C7-for-CNC-XYZ-/250594423125?pt=LH_DefaultDomain_0&hash=item3a58977155#ht_551wt_1165
[22:33:06] <tjb1> So for that, I would need 16mm collars, 16mm thrust bearings, 16mm support block
[22:33:26] <jdh> he sells them all together also
[22:34:17] <jdh> 250818484320
[22:34:20] <tjb1> http://www.ebay.com/itm/1antibacklash-ballscrew-1605-430mm-C7-BK-BF12-coupler-/250528368890?pt=LH_DefaultDomain_0&hash=item3a54a788fa#ht_608wt_1165
[22:34:27] <jp_> I use thrust on my knee mill with no issues
[22:34:40] <jdh> or that
[22:35:06] <tjb1> Well I am just a little confused as to how im going to attach it to my stepper unless I have them machine the end or make a special adapter from 16mm-3/8"
[22:35:22] <tjb1> I know you cant take it apart...
[22:35:30] <jdh> have him machine the end.
[22:35:49] <jp_> You can take them apart
[22:36:04] <tjb1> Without dropping balls everywhere?
[22:36:06] <jdh> those are already machined for the bearings
[22:36:18] <jp_> that what the bucket underneath is for
[22:36:44] <jdh> they are finicky to repack, but not a big deal
[22:36:45] <tjb1> jdh: are those bearings also thrust?
[22:37:04] <jp_> it's not a job you want to rush but it can be done
[22:37:29] <jdh> one end is radial only, one end has thrust
[22:37:58] <jp_> im sure the screw is barely case hardened as well so cutting the ends would not be a big deal either
[22:38:05] <jdh> I think connor got a set from him like that. Might ask him.
[22:38:28] <tjb1> Wonder how high those blocks are
[22:38:36] <jdh> not a big deal, but also not enough $$ to worry about having them do it.
[22:39:27] <jdh> I got AC bearings for my mill. They were fairly cheap.
[22:40:06] <tjb1> ac bearings?
[22:40:13] <tjb1> Oh angular contact
[22:40:27] <jdh> doubt they really added much over the plain thrust bearings.
[22:40:45] <tjb1> Connor: you awake?
[22:41:28] <tjb1> Im thinking its not worth it to go for ball screw over acme on my Z
[22:42:47] <jp_> where is a good place for acme with preload nuts?
[22:43:25] <tjb1> anti backlash?
[22:43:32] <jp_> yes
[22:43:54] <tjb1> cncrouterparts has them from dumpstercnc
[22:44:20] <tjb1> http://www.cncrouterparts.com/dumpstercnc-acme-assembly-p-36.html
[22:45:52] <tjb1> Damn I dont know, might be very close to just go with ballscrew
[22:46:44] <jp_> 5/8 rolled ball screws at mcmaster carr are pretty cheap too
[22:47:01] <tjb1> $32 for that anti backlash nut, $16 for the acme screw, $30 for 2 bearing blocks, $8 for 2 thrust bearings, $6 for 2 collars
[22:47:20] <tjb1> thats $90...
[22:47:49] <tjb1> Plus some type of coupler
[22:47:56] <tjb1> I think its $20 for an oldham
[22:48:09] <jp_> http://www.mcmaster.com/#ball-screws/=iu7yxu
[22:49:12] <jp_> for some reason 5/8 is the cheapest
[22:49:28] <jp_> made by thompson
[22:49:46] <tjb1> $36 for 2 ft, $30 for nut without flange…no idea on support blocks
[22:51:21] <jp_> not much to make support blocks if you have a friend with a mill
[22:51:28] <tjb1> If I go with thrust washers, can I just have 2 of them with each on the inside of the support blocks
[22:51:52] <tjb1> Or do you need one on each end of support blocks
[22:52:11] <jp_> use a regular bearing at one end and trap the other between thrusts
[22:52:59] <tjb1> So the block near the stepper would just have a radial bearing and the other end would have the radial and a thrust on each side with collars
[22:53:20] <jp_> the other way
[22:53:34] <tjb1> constrained at the stepper side?
[22:53:39] <jp_> yes
[22:53:45] <tjb1> Alright, thanks :)
[22:53:56] <jp_> no problem
[22:54:46] <tjb1> That just took care of my Z
[22:56:07] <jp_> cool want finish of my x y and z for me
[22:56:15] <jp_> lol
[22:56:37] <tjb1> I have enough problems :)
[22:56:50] <jp_> i hear ya
[22:57:05] <tjb1> I have to buy everything within a budget of $2300
[22:57:17] <jp_> hey thats not bad
[22:57:26] <tjb1> Its gonna be tight
[22:57:50] <jp_> rack and pinion on the others?
[22:57:56] <tjb1> Yep
[22:58:02] <jp_> perhaps timing belt?
[22:58:24] <tjb1> The rack is surprising cheap
[22:58:41] <tjb1> $250 for 26' delivered
[22:58:56] <jp_> how accurate?
[23:00:13] <tjb1> http://www.mooregear.com/gearracks.html
[23:00:22] <tjb1> I dont see anything but I think just about everyone uses them
[23:02:17] <jp_> true
[23:02:54] <jp_> what are you planning to use for guides
[23:03:45] <tjb1> the cncrouterparts carriages
[23:05:13] <jp_> check out anheim automation they have low cost thk style rails
[23:06:24] <tjb1> well my x is 10' long and y is 6' long
[23:08:51] <jp_> what r u using for motors and drives
[23:09:12] <tjb1> nema 23 and gecko g540
[23:09:49] <r00t4rd3d> for that big i would use 32
[23:10:16] <tjb1> Its dual drive on x
[23:10:20] <tjb1> this is also a plasma table ;)
[23:10:26] <r00t4rd3d> oh
[23:10:46] <jp_> thats why i would of went timing belt
[23:11:26] <r00t4rd3d> Who knew who helen brown was before today?
[23:11:36] <tjb1> I still dont know who that is
[23:11:41] <r00t4rd3d> lol me either
[23:12:01] <r00t4rd3d> all the news sites keep calling her a legend and shit
[23:12:21] <r00t4rd3d> never heard her name before ever
[23:12:53] <tjb1> What is your method for the timing belt jp_
[23:14:00] <jp_> if you just moving a torch around i would just use a timing belt drive on x and y
[23:14:11] <tjb1> well it will also do router
[23:14:57] <jp_> im building one next to test out the belts as arouter my experience says it should be fine
[23:15:14] <tjb1> Do you have a picture of how this works?
[23:15:40] <jp_> juat a loop of belt pulley at each end
[23:15:50] <jp_> motor drives the pulley
[23:16:06] <jp_> ends attach to the axis its moving
[23:16:41] <tjb1> Sounds easy
[23:17:08] <tjb1> Where is a source for the timing belt?
[23:17:51] <jp_> ive positioned 1000lbs of glass moving at 10kmph stopping within .001 on automated machinery
[23:18:13] <jp_> mcmaster or sdp si
[23:19:56] <tjb1> http://www.mcmaster.com/#timing-belts/=iu8ffn
[23:20:00] <tjb1> That what I am looking for?
[23:20:46] <jp_> http://www.mcmaster.com/#timing-belts/=iu8e2q
[23:21:03] <jp_> urethane with kevlar
[23:21:36] <tjb1> White belt
[23:22:00] <jp_> havent tried it out on a router yet but im sure it would work. steppers might not but with servos
[23:22:03] <jp_> yes
[23:22:16] <tjb1> .2 pitch, 1/2" wide?
[23:22:37] <jp_> 1"wide
[23:22:59] <jp_> L series
[23:23:04] <tjb1> Thats more than the rack and pinion
[23:23:10] <Jymmm> tjb1: http://www.youtube.com/watch?v=5RBne0EXbTc
[23:24:03] <tjb1> I suppose I would have to add something to keep it tensioned because of the speed of the router
[23:24:35] <jp_> yes one end of the belt would be fixed the other tensioned
[23:24:35] <Jymmm> router?!
[23:24:55] <Jymmm> your moving a router using a belt?!
[23:24:57] <tjb1> jp_: I would have nearly $400 in belting
[23:24:59] <tjb1> No
[23:25:44] <Jymmm> theres no spring tension, just adjust the belt when installed
[23:25:45] <tjb1> Just exploring options Jymmm
[23:26:07] <Jymmm> belt for a router is not an option, too much mass.
[23:26:11] <jp_> you can tell how much i dont like racks eh!
[23:26:14] <Jymmm> and force
[23:26:21] <jp_> not true
[23:26:44] <tjb1> My gantry is probably going to be around 70#
[23:27:22] <Jymmm> 2.5HP router 25000 RPM, cutting into material is too much force for a belt
[23:27:46] <Jymmm> unless you like to replace them often
[23:28:42] <jp_> im sure it could work fine soon i will know the answer
[23:30:12] <tjb1> Well rack is cheaper so I am going that direction :D
[23:30:37] <Jymmm> Everything that we tell you is what we consider "best practices". Of course, only YOU know your own requirements, so you may feel you need to do something we told you not to. Just don't say we didn't warn you.
[23:30:38] <tjb1> I had a good idea for running the belt through the extrusion
[23:30:39] <jp_> i dont blame you
[23:31:49] <toastydeath> lol a belt
[23:33:15] <jp_> Considering i build automated machinery for a living i can live with that. I have used that type of drive system on jobs and like the idea of trying it out on a router
[23:34:47] <Jymmm> jp_: you've used belts for something that exerts horizontal cutting forces in hard material?
[23:35:34] <jp_> forces and hard are relative terms when compared to design
[23:35:54] <Jymmm> jp_: Fine, give examples, video even better
[23:40:04] <jp_> how bout i just build it and see where it goes. simply cant be done is not good enough for me. I need to see it. I understand forces are involved but i also understand materials are out there to deal with those forces
[23:41:29] <r00t4rd3d> my router is 26,000 rpms and I use a belt
[23:42:20] <jp_> What size motors r u using?
[23:42:24] <r00t4rd3d> 23
[23:42:32] <jp_> Max torque
[23:42:38] <r00t4rd3d> no clue
[23:42:51] <jp_> not much is what i was getting at
[23:43:10] <r00t4rd3d> Holding Torque: 90N.cm
[23:43:20] <jp_> gear ratio?
[23:43:28] <r00t4rd3d> 1;1
[23:43:42] <r00t4rd3d> well my motor has a 20 and my screw has a 22
[23:44:46] <r00t4rd3d> i use these
[23:44:47] <r00t4rd3d> http://www.cncrouterparts.com/nema-23-rp-motor-pulley-p-71.html
[23:45:12] <r00t4rd3d> this belt
[23:45:12] <r00t4rd3d> http://www.cncrouterparts.com/nema-23-rp-drive-belt-p-69.html
[23:47:50] <jp_> no what we were discussing was using a belt as a replacement for the rack
[23:48:34] <r00t4rd3d> oh
[23:48:43] <r00t4rd3d> i only read some stuff
