[00:04:52] <lwizardl> ah never thought of that
[01:58:23] <DJ9DJ> moin
[02:32:29] <Loetmichel> mornin'
[04:23:26] <DJ9DJ> re
[06:16:58] <aircraft> i'm think about swithing my cnc to serial interface, can someone point me to a good implementation?
[06:17:25] <jthornton> serial?
[06:17:42] <aircraft> yes
[06:17:57] <aircraft> to RS485 for example
[06:18:29] <jthornton> you would have to have some smart hardware on the other end
[06:18:39] <jthornton> but why serial?
[06:19:23] <aircraft> because parallel has limited number of ios
[06:19:55] <jthornton> Mesa 5i25 7i76 combo is the way to go for a stepper driven machine
[06:19:58] <aircraft> i kno what i will need some smart hw and plan to make it
[06:21:12] <jthornton> you will also need to write a program to go along with your smart hardware
[06:21:58] <aircraft> i have some experience already
[06:22:26] <aircraft> but it was not realtime
[06:22:41] <jthornton> neither will the serial interface
[06:23:06] <jthornton> so this is not to gain I/O but for the experience?
[06:28:36] <aircraft> for both i think
[06:30:24] <jthornton> you do know that for $200 you get 5 Axis of step &dir step motor or servo motor drives and also provides a spindle encoder interface, isolated analog spindle speed control and 48 isolated I/O points for general purpose field I/O use. with a 5i25/7i76?
[06:30:58] <jthornton> I guess that depends on what part of the earth your located in though
[06:43:32] <aircraft> you're right but it's not suitable for laptop for example
[06:47:37] <Valen> laptops aren't generally suitable for running EMC due to delays anyway
[06:48:32] <aircraft> Valen, why?
[06:49:42] <aircraft> i have small desktop CNC machine and building full featured control rack for it is too much
[06:54:38] <jthornton> what are you using now to run your desktop CNC machine?
[06:55:17] <aircraft> chinese blue board + PCMCIA Parallel card
[06:56:34] <jthornton> what software are you using?
[06:56:50] <aircraft> linuxcnc2.5
[06:57:18] <Valen> aircraft: google at linuxcnc latency
[06:57:21] <jthornton> just curious what is the latency of your laptop?
[06:58:34] <jthornton> aircraft you might look at the gs2 component for inspiration. It uses modbus over the serial port
[06:58:49] <aircraft> why it must be big for laptop?
[06:59:35] <jthornton> what is "it"?
[06:59:37] <aircraft> many people succefully using Atom boards
[06:59:56] <aircraft> latency
[07:00:02] <jthornton> the Atom is a favorite motherboard
[07:00:24] <jthornton> laptops have power saving hardware that causes the latency to be big
[07:00:33] <jthornton> desktops do not have this problem
[07:01:15] <aircraft> Atom doesn't?
[07:02:53] <jthornton> desktop motherboards do not have the same "features" that laptops do
[07:05:02] <aircraft> what features exactly?
[07:05:11] <jthornton> power saving
[07:05:15] <aircraft> speedstep?
[07:05:32] <jthornton> ?
[07:06:06] <Valen> run latency test and have a look
[07:06:24] <jthornton> laptops are designed to run on battery so they have hardware to conserve power that interrupts the CPU
[08:31:05] <jthornton> yea the tap drill program is working nice... now to find a tap spreadsheet that has major and minor diameters on it
[08:35:31] <mazafaka> jthornton: Do you use
http://www.micro-machine-shop.com/drill_tap_bits.jpg or gust something usual
[08:36:17] <mazafaka> http://www.micro-machine-shop.com/tapped_threads_reference_tables.htm
[08:39:29] <jthornton> I've used a tap/drill combo for one job that was in sheet metal
[08:39:41] <jthornton> I've never used a tap jig
[09:10:43] <aircraft> jthornton, where i can found more info about rt issues on laptops?
[09:16:25] <Jymmm> Laptops have power management that interferes with real time operations.
[09:18:24] <aircraft> very abstract
[09:18:51] <aircraft> i need more detailed info
[09:26:12] <mazafaka> aircraft: i tried two laptops, one was not working with RTAI at all, another one worked, but I think it was badly cooled down in this mode
[09:52:45] <aircraft> so can we say that most laptops will not work stable with linuxcnc?
[09:53:16] <aircraft> opposing to desktop boards
[09:53:27] <JT-Shop-2> the software will be stable on a laptop but real time will not and you will miss steps from time to time
[09:54:55] <aircraft> is it true for most laptops?
[09:55:53] <JT-Shop> aye
[10:23:40] <mazafaka> aircraft: exactly. oposite to desktops, they're badly-cooled thingies and manufacturers understand it and make them reliable by some means. Another question is, why can not you afford a desktop with old CRT monitor altogether for somewhat like 100 USD?
[10:24:47] <skunkworks> if that...
[10:25:54] <aircraft> mazafaka, it will take much more place tham my cnc router :)
[10:26:45] <aircraft> actually i have 2 laptops and both orks fine via parallel pccard
[10:27:37] <mutilator> orly?
[10:27:39] <mutilator> what card?
[10:27:48] <mutilator> cause i'd prefer to use my old laptop to a old desktop
[10:28:22] <JT-Shop> aircraft: a BOX525 Atom board is smaller than most laptops :P
[10:28:32] <aircraft> it is noname brand card on OXmPCI952 chipset
[10:28:57] <aircraft> JT-Shop, yep
[10:29:07] <skunkworks> I have had only 1 laptop so far that had decent realtime performance - you are lucky
[10:29:34] <skunkworks> The card isn't what dictates the realtime performance - it is the computer
[10:29:44] <mazafaka> aircraft: at work, we have some DOS-based thingie which does not miss steps (although the machine turns off with errors sometimes). But Ubuntu-based LinuxCNC offers QCAD and HeeksCNC right in RTAI mode, so it worth to have such a workstation.
[10:30:35] <aircraft> JT-Shop, btw, is were any differens between ITX atom board and netbook motherboard?
[10:31:11] <mazafaka> netbook = small size, bad cooling, manufacturer's alteration in BIOS
[10:31:25] <mazafaka> if I understand it correctly.
[10:31:32] <aircraft> a just ordered HP mini110 motherboard for 20$
[10:32:22] <aircraft> it doesnt have cooler but i can install large fan with heatsink on it
[10:32:34] <JT-Shop> I get warnings about dos style line endings, how can I find and remove them
[10:36:40] <mazafaka> JT-Shop: doesn't linux text editors understand both, linux and dos-style line endings, or does they?
[10:37:04] <JT-Shop> sure, but emc complains
[10:39:16] <mazafaka> A ferocious death is awaiting all the enemies / All the parasites of the working classes / Vengeance and death for all the plutocratic tsars / The solemn hour of victory is near.
[10:41:37] <mazafaka> https://www.youtube.com/watch?v=8-C-tjQK0TY i think i will work in a secret uneground shop of *one* plant
[10:41:44] <alex_joni> varshavianka?
[10:42:10] <mazafaka> heh, yes, although I do not understand why it's a Polish song...
[10:42:36] <mazafaka> but Poland was attacked first
[10:45:24] <L84Supper> that's when Marxism was Marxism
[10:47:22] <mazafaka> who knows... some say, they even tried to destroy the institution of family on the territory of Russia just to conquer the proletariat
[10:48:09] <mazafaka> e.g. there were the demonstrations of naked lesbians in Moscow, and so forth.
[10:48:52] <mazafaka> whole the bundle of stuff
[10:49:22] <aircraft> mazafaka, are you russian?
[10:50:02] <mazafaka> yeah
[10:50:20] <aircraft> mazafaka, i'm from Novgorod
[10:50:56] <mazafaka> Russian Roverbook Nautilus XX-something worked with RTAI. When my Asus X51RL was in guarantee because of problems with RAM
[10:51:00] <L84Supper> http://www.youtube.com/watch?v=6qLzQ4uOvio Americas Son Brainwashed :)
[10:51:06] <mazafaka> oh, I'm from Kuzbass
[10:52:19] <mazafaka> L84Supper: famous american comediant
[10:54:45] <aircraft> mazafaka, btw i've repaired my friend's X51RL recently and notice that cooler always running on full speed
[10:55:07] <mazafaka> L84Supper: We in Russia love him so much! Him and Chevy Chase!
[10:55:46] <mazafaka> aircraft: yeah, but i do not turn it off already three years, and cats sleep on it.
[10:56:26] <mazafaka> aircraft:
http://a.d-cd.net/eb2732u-960.jpg
[10:57:39] <aircraft> i even thought it's thrmal circuit issue
[10:58:13] <aircraft> buth thn found video on youtube where it running with same noise
[10:58:39] <mazafaka> yeah, but sometimes it is very silient
[11:15:17] <r00t4rd3d> http://i.imgur.com/f9YYI.jpg
[11:15:28] <r00t4rd3d> top im about to cut for a pbox
[12:08:44] <aircraft> maybe good option for Atom netbook www.ebay.com/itm/220506407931
[12:12:03] <aircraft> or nettop box
[12:17:54] <IchGuckLive> Hi all B)
[12:22:30] <IchGuckLive> someone knows if there is a new feature request page for linuxcnc or only true the devels mailinglist
[12:32:36] <jthornton> http://imagebin.org/232399
[12:35:33] <Jymmm> what is 50% threads?
[12:35:49] <IchGuckLive> the Depth
[12:36:12] <Jymmm> that doesn't make sense
[12:37:20] <Jymmm> 1/4-20 @ 2" or 4" length would be "depth" to me.
[12:40:31] <IchGuckLive> oh on a pin it means there is only 50% of the length with tread
[12:43:15] <jthornton> http://imagebin.org/232401
[12:44:14] <jthornton> crap wrong one
[12:44:15] <jthornton> http://imagebin.org/232402
[14:50:21] <jrshaul> Has anyone here cut depron (or another polystyrene foam) with a laser?
[14:50:42] <jrshaul> Most people use a really small laser, sometimes with a nitrogen feed. I wantto use a larger (~100W) laser, but without.
[14:53:14] <fragalot> jrshaul: I think there are lots of 75W pre-filled chinese laser tubes on ebay
[14:53:21] <fragalot> they seem to work alright
[14:53:32] <jrshaul> The laser I have. The information on how to cut without mucking up the oam or the optics I don't.
[14:53:40] <jrshaul> (It's not my machine. I just get to use it.)
[14:53:52] <fragalot> Ah. No idea ^_^
[14:54:53] <c60> Is there any howto's about using gantrykins for a dual stepper axis?
[14:55:30] <andypugh> c60: Are you sure it is worth the trouble?
[14:55:54] <c60> well, I'd like to be assured it's square when I do a homing.
[14:56:09] <andypugh> You have two sets of limit switches?
[14:56:13] <c60> yes
[14:56:49] <c60> I have it all working with trivkin I guess right now.
[14:56:59] <andypugh> There is a sim-gantry component in the sample files, take a look at that. (in fact, have a play around with the sim to see if you can handle the inconvenience)
[14:57:18] <c60> what sort of inconvenience's does it impart?
[14:57:31] <andypugh> I _think_ that there might be a crucial line missing from the INI file if the sample too. Let me take a look.
[14:58:51] <c60> that would be helpful
[15:00:05] <andypugh> Right, I think that the [TRAJ]MAX_ACCELLERATION and [TRAJ]DEFAULT_ACCELLERATION are commented out. They need to not be, and the numbers must be less than the stepgen accell from the [AXIS_N] sections.
[15:01:28] <andypugh> The drawbacks are that you need to home in joint mode then switch to World mode. There is something wierd about the jogging too. I think you can only jog in one cartesian direction at a time or something similar.
[15:02:20] <c60> those aren't too major of an issue. I'm assuming you could always just go into MDI mode and say G1 X500 Y500 or whatever
[15:02:36] <c60> It said you could only jog continous not incremental
[15:02:37] <andypugh> Yes.
[15:02:39] <c60> no biggy
[15:02:42] <andypugh> That too.
[15:03:20] <c60> So would I be best to just take to the sim files and modify them to work, or try to hack in the sim stuff into my existing configuration?
[15:03:54] <andypugh> The best idea is probably to make a copy of your current config directory, change the name of the folder and the INI file inside, then work on that copy. Then you can start either as the mood takes you.
[15:05:50] <andypugh> And I would probably just edit the config. It's actually just a case of changing loadrt trivkins to loadrt gantrykins coordinates=XYZY (or whatever your config is) That's all it takes, I think.
[15:06:48] <c60> for sure, I really only need to run it when I'm off square,
[15:13:23] <jthornton> anyone want to play with this
http://imagebin.org/232402
[15:15:37] <andypugh> Want to, yes. Have time for? No. I am involved in an arms-race with burglars. I am ahead so far, but they have come back three times this week.
[15:15:52] <jthornton> holy crap
[15:16:14] <jthornton> and you can't get the bobbies to hang around your place for a while
[15:16:20] <andypugh> Currently writing the G-code to make some more security stud things.
[15:16:23] <c60> time to get some camera's installed, and maybe plant a gps in something for them to steal
[15:16:59] <andypugh> What good would it do to know here some of my stuff was? I want them to not steal anything.
[15:17:30] <andypugh> And I am not sure why I would want pictures of them as a souvenir either.
[15:17:33] <c60> I guess it just depends if it's the same burglar or not,
[15:18:39] <andypugh> The neigbours reckon they recognised them.
[15:19:04] <c60> I saw a neat alarm once that was basically a smoke machine, it'd fill up your house or whatever and start strobing lights so they couldn't see anything. and it would make your house look super suspicious smoke and red billowing out.
[15:19:11] <jthornton> guessing you don't have a "rent a rottweiler" dealer nearby
[15:19:48] <andypugh> They only tried to get in once. (broke the garage/workshop door out of the tracks, but one corner was pinned down by
https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5800014699280725666
[15:20:04] <c60> but these aren't necesessarily deterrants.
[15:20:20] <andypugh> Then they came round again (I assume in case I hadn't fixed the door)
[15:20:42] <andypugh> My fear is that they will come round with tools next. So far they have been using brute force.
[15:21:06] <andypugh> So, I am making another of those for the other corner.
[15:21:21] <jthornton> I'll let you get back to work then
[15:21:22] <andypugh> The problem is that they have now seen how full of goodies that particular garage is.
[15:21:44] <jthornton> and the police are no help?
[15:22:01] <andypugh> What can they do?
[15:22:12] <jthornton> stake out the place
[15:22:15] <andypugh> There are a lot more garages than cops.
[15:22:20] <Tom_itx> so wire the door to mains
[15:22:50] <andypugh> Burglary is a low priority compared to wiring code violations :-)
[15:22:54] <jthornton> yes, but yours is of interest to them and they keep coming back so it is unique
[15:23:22] <andypugh> At least one other garage (that I know of) was attacked the same day.
[15:23:30] <jthornton> if you were closer I'd lend you the ballista
[15:23:35] <andypugh> I don't think they care _which_ enduro bike they steal.
[15:24:00] <jthornton> better get busy then and fortify your door up
[15:24:39] <Tom_itx> someone stole my rear fence gate once. nothing else
[15:25:54] <c60> A similar story was all over the news today in Calgary, someone's house had been burglarized several times in a couple weeks, so they put up camera's and of course had the picture of the theif on the local tv, the cops said it's very helpful when people do the detective work for them, but they didn't say they had arrested him yet,
[15:26:13] <c60> but a picture and gps coordinates of where they are might make the cops job too easy to pass on\
[15:29:44] <andypugh> OK, so why isn't my ngc file changing?
[15:30:12] <andypugh> (editing on one machine, viewing on another)
[15:30:51] <archivist> reload
[15:31:16] <archivist> save to the right place
[15:31:34] <cradek> stop making your life difficult and put the mac away
[15:31:38] <andypugh> I am fairly sure I am doing both.
[15:32:13] <andypugh> cradek: There are chairs here. The Linux machines are in the garage with horible keyboards.
[15:33:42] <archivist> spose I should unload todays pics from the model engineer ex
[16:16:06] <JesusAlos> Hello
[16:16:18] <JesusAlos> Hi Andypugh
[16:16:31] <andypugh> Hi
[16:16:41] <JesusAlos> I'm encoder>PLT port
[16:17:42] <andypugh> OK.
[16:21:43] <andypugh> Is the encoder working?
[16:22:48] <JesusAlos> for now I have not tried
[16:23:41] <andypugh> Ah, I thought you said you were using that,
[16:23:44] <JesusAlos> I will listen to you and I will buy one 5i25 and 7i777 masa card
[16:24:07] <andypugh> Oh, I see. You were just reintroducing yourself?
[16:24:12] <JesusAlos> no
[16:24:33] <JesusAlos> on my machine use stepper motor
[16:25:03] <JesusAlos> but on other machines I will use servomotor
[16:25:32] <andypugh> Good luck. I need to wander off to the workshop now.
[16:26:25] <JesusAlos> ok
[16:26:44] <JesusAlos> can i see some work?
[16:27:00] <JesusAlos> your work
[16:38:32] <andypugh> I am still mainly making machines. And todays project is not at all interesting.
[16:54:22] <JesusAlos> thear sirs
[16:54:59] <JesusAlos> There are eny way to use Galil cards with EMC2
[17:51:01] <JT-Shop> does Galil cards have step and direction or velocity input?
[17:52:06] <jdh> I'm resisting the grammar correction.
[17:52:48] <JT-Shop> :P I just walked 5 miles out in the woods and was too tired to correct it once I saw it
[17:53:05] <jdh> no clue what you are talking about specifically, but I have some galil cards at work that do either
[17:53:17] <JT-Shop> neither do I
[17:53:23] <jdh> they are 1826's maybe?
[17:54:15] <JT-Shop> I've never seen one up close
[17:54:33] <jdh> they came with some canned systems
[17:54:40] <JT-Shop> ah
[17:56:21] <JesusAlos> I want to use a 5i25 and 7i777 Mesa cards
[17:56:28] <jdh> one is on a 3 axis engraving system with servos. 6 others with probably the most expensive single axis step-dir system known.
[17:57:21] <jdh> huge card, big cable, really nice breakout board. 2 sets of wires going to a stepper drive.
[17:57:22] <JesusAlos> but Pncconf wizard no have 5i25 card option choice
[17:57:27] <JT-Shop> JesusAlos: does your drive take velocity input? and do you have encoder feedback?
[17:58:08] <JesusAlos> I don't Know the velocity but i have encoder control
[17:59:11] <JT-Shop> does the drive use +- 10vdc signal to control the servo?
[17:59:23] <jdh> yes
[17:59:29] <JesusAlos> yes
[17:59:36] <JT-Shop> JesusAlos: have you read the pncconf section of the forum?
[17:59:48] <JesusAlos> no
[17:59:53] <jdh> (heh, I was still thinking of the galil system)
[18:00:17] <JT-Shop> JesusAlos: read that section about configuring the 7i77 on pncconf
[18:00:31] <JesusAlos> ok
[18:00:57] <JesusAlos> why about galil?
[18:02:51] <jdh> I was just looking at scrollback, but didn't go far enough back for context.
[18:04:27] <JesusAlos> when i try sudo apt-get update/upgrade
[18:04:40] <JesusAlos> EMC2 software update to?
[18:28:27] <JesusAlos> best regards JT-Shop
[18:28:36] <JesusAlos> i read the forum
[18:29:02] <JesusAlos> the pncconf wizard runs with 5i25 Mesa card
[18:49:01] <JesusAlos> good night
[18:49:39] <Nick001-Shop> andypugh: What mesa cards should I be using with those velocity drivers for stepper motors?
[18:56:29] <r00t4rd3d> My latest doings:
[18:56:29] <r00t4rd3d> http://imgur.com/a/iKOQ8
[18:56:56] <jdh> how long did the front take?
[18:57:48] <r00t4rd3d> 2.5 hours
[18:57:52] <r00t4rd3d> at 18ipm
[19:03:07] <andypugh> Nick001-Shop: I am not sure what you mean by "velocity drivers"
[19:05:34] <Nick001-Shop> you gave me a link www.zappautomation.co.uk/uim24302a-self-pulsing-miniature-stepper-driver-p-556.html?cPath=9_3_4 for them.
[19:12:38] <Nick001-Shop> back in a while
[19:13:55] <tjb1> r00t4rd3d: You cut the whole thing in 2.5 hours?
[19:14:28] <r00t4rd3d> no just one panel
[19:14:33] <r00t4rd3d> front panel
[19:14:48] <r00t4rd3d> the top only took 30 minutes
[19:14:55] <andypugh> r00t4rd3d: What wood?
[19:14:59] <r00t4rd3d> oak and pine
[19:15:08] <r00t4rd3d> oak sides, pine rest
[19:16:26] <andypugh> Yeah, thought so. I don't find pine to be a particularly attractive wood. But then I find myself strangely tempted by
http://purpleheartflooring.com so don't pay much attention to me.
[19:17:00] <r00t4rd3d> i dont like pine either.
[19:17:24] <tjb1> Im getting better at TIG so I guess I accomplished something today
[19:17:25] <r00t4rd3d> i let them pick the wood though
[19:18:23] <jthornton> andypugh, how is the arms race going?

[19:19:58] <andypugh> I got the G-code debugged and made one rod/knob thing. I will do the other and the brackets tomorrow. My enthusiasm waned when faced with a 10' length of 25mm stainless bar and a 20mm spindle through-hole. So I need to hacksaw off bite-sized chunks.
[19:20:19] <Tom_itx> got a chop saw?
[19:20:47] <andypugh> No, and I am not likely to buy one in the current circumstances.
[19:20:59] <jp_> pcw_home, could the 7i44 be used somehow with hiperface encoders?
[19:21:01] <Tom_itx> i sometimes use an abrasive wheel too
[19:21:05] <andypugh> (I don't really have the space for one either)
[19:21:18] <jthornton> can you mill the bar into smaller chunks?
[19:21:21] <Tom_itx> small 4" angle grinder with a cutoff wheel
[19:21:36] <jthornton> yea that works for me
[19:21:46] <jthornton> I use a 4 1/2" though
[19:21:56] <Tom_itx> yeah i think mine is as well
[19:21:58] <andypugh> The hacksaw is reasonably expedient. The angle grinder makes too much noise for midnight.
[19:22:20] <Tom_itx> give you a good workout anyway
[19:22:39] <andypugh> (and the angle grinder is living in the house so as not to be usable by thieving scrotes to bypass my secondary security if they do get in)
[19:23:02] <andypugh> I have hacksawed a 6" bar once. But it took a while.
[19:24:09] <Tom_itx> i should post a result here
[19:24:36] <andypugh> jp_: If the encoders are RS485 then the 7i44 will get the signals into an FPGA card. The question then is if the FPGA card can do anything with the data.
[19:24:40] <jthornton> I don't think I've hacksawed stainless before, but I have hacksawed some big chunks of steel
[19:24:50] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/Lathe/thread1.jpg
[19:24:58] <Tom_itx> finished those up the other day
[19:25:08] <jp_> andypugh, hiperface is part 485 plus sine cos
[19:25:20] <Tom_itx> i sawed some 5/8 stainless bar the other day
[19:25:24] <Tom_itx> wasn't so bad
[19:25:35] <Tom_itx> no worse than mild steel really
[19:26:30] <andypugh> The sine-cos part is the hard bit. You need fast analogue, and there isn't a lot of that for LinuxCNC.
[19:27:04] <jp_> andypugh, what about the new mesa serial analogue cards?
[19:27:15] <andypugh> You might be able to modify my Arduino Resolver code. That samples sine-cos and converts to position, then sends the data to a Mesa UART at 1Mbit.
[19:27:40] <jp_> i was going to ask if you still had those sheilds
[19:27:57] <Tom_itx> that pin is holding these on:
http://tom-itx.dyndns.org:81/~webpage/cnc/Lathe/Pic_1010_002.jpg
[19:28:39] <Tom_itx> hand carved brazillian walnut
[19:28:42] <andypugh> You wouldn't want or need the shield, that mainly provides excitation for the resolver.
[19:29:07] <jp_> oh i thought you might of had a 485 driver on it
[19:29:29] <andypugh> The UART is 5V ttl
[19:29:49] <jp_> haven't taken a hard look at it
[19:30:04] <jp_> the shield that is
[19:30:58] <andypugh> http://www.ebay.co.uk/itm/BAUMULLER-BM4-FENC-02-001-000-SINCOS-m-HIPERFACE-XLNT-/350482442103?pt=BI_Control_Systems_PLCs&hash=item519a61a777
[19:31:36] <andypugh> You probably need to talk to PCW, he probably has thoughts on the subject of Hiperface.
[19:32:34] <jp_> yeah. I know ssi is possible just was wondering how much of a strech hiperface was
[19:33:13] <jthornton> Tom_itx, did you see the threading software?
[19:35:09] <Tom_itx> nope
[19:35:54] <jthornton> http://imagebin.org/232402
[19:36:12] <Tom_itx> oh
[19:36:17] <Tom_itx> yes, i did see that
[19:36:19] <jthornton> I still have to add the threading part with wire measurements etc.
[19:36:57] <jthornton> so you pick a thread type, then the actual thread and it gives you all the info needed to tap or thread
[19:37:13] <Tom_itx> nice
[19:37:14] <jthornton> also you can pick what drills you have to choose from
[19:38:14] <Tom_itx> i try to keep a full 115? piece set of sharp bits
[19:38:44] <Tom_itx> and a few smaller ones for pcboards
[19:39:19] <jthornton> I like it so far to be able to pick a bit to get the thread percentage you want for the material your threading
[19:39:27] <Nick001> back
[19:39:41] <jthornton> the OD part will give all the info needed to measure the thread pitch with thread wires
[19:40:07] <Tom_itx> so far when i need that i go to the handbook
[19:40:53] <jthornton> me too, but if it is right there on your machine...
[19:41:05] <Tom_itx> yeah
[19:41:52] <jdh> Ihave one on my phone. On the linuxcnc box would be nice though.
[19:42:09] <jdh> I usually google drill tap chart and pick something
[19:43:01] <Tom_itx> i got charts on the wall by the drillpress and lathe
[20:05:16] <Jymmm> Oh look... this place is crap and I can toss their menu and have a place on the wall for soemthing else!
[20:05:56] <Jymmm> O-ring chart!
[20:23:16] <tjb1> Why does a coupler for a 3/8" shaft use like a #1 or #2 screw?
[20:32:01] <jdh> how about a 4-40 instead. or maybe a 6-32
[20:42:47] <tjb1> jdh: Im gonna put a 10-32 in it
[20:42:51] <tjb1> Its .315 thick...
[20:43:02] <jdh> knock yourself out!
[20:47:24] <tjb1> Actually its a 5-6
[20:47:32] <tjb1> Probably a 5
[20:47:48] <jdh> uh huh
[20:48:08] <mrsun> i always go 5-56 or WD-40
[20:48:10] <mrsun> but thats me :P
[20:48:20] * mrsun has no idea what numbers you are throwing around :P
[20:48:42] <jdh> mrsun: teh bore of his craque pipe?
[20:49:11] <mrsun> dont think he should smoke 5-56 nor wd-40
[20:52:41] <tjb1> jdh: #5 or #6 not a #5-6 :P
[20:52:59] <jdh> you found something in the .us that uses a #5?
[20:53:12] <tjb1> I didnt take the screw out
[20:53:19] <tjb1> I was just going by what allen wrench it uses
[20:53:19] <jdh> I'd be impressed.
[20:54:45] <jdh> but, speaking of oddball sizes. At work, we had a GE circuit breaker. Standalone module with an option for a remote reset. The bolts holding the flip-part-lever-thingie were bigger than 3mm, smaller tham 4mm. Bigger than #6, smaller than #8
[20:57:14] <tjb1> Would you say a metric bolt with an outside diameter measuring 2.75mm = M3?
[20:57:43] <jdh> quite likely.
[20:58:46] <jdh> the only m3 I could find to check was a m3 set screw
[20:58:52] <mrsun> shouldnt it be close to 3mm ?
[20:58:59] <mrsun> there is M2.5 etc also
[20:59:04] <mrsun> at those small sizes
[20:59:24] <jdh> 2.75 seems just a little small.
[20:59:49] <tjb1> let me pull one out again and check
[21:00:05] <mrsun> M2.6 there is also
[21:00:41] <mrsun> http://www.engineersedge.com/hardware/metric-external-thread-sizes1.htm
[21:01:04] <mrsun> M3 has Max 2.98mm Min 2.874
[21:01:10] <jdh> just a little small
[21:01:23] <tjb1> well this one is 2.9
[21:01:28] <tjb1> Maybe that one was screwed up
[21:02:12] <mrsun> aparently :P
[21:02:23] <mrsun> (the thing i wrote)
[21:02:33] <jdh> or it's a 4-40
[21:02:39] <tjb1> Its metric :)
[21:02:59] <tjb1> I use to go to lowes to try and get this stuff…I have since stopped wasting my time
[21:03:06] <jdh> good move.
[21:03:07] <mrsun> is it computer stuff or ?
[21:03:12] <tjb1> I couldnt even get a 10-32 SHCS
[21:03:22] <tjb1> mrsun: Its for the blocks on linear rails
[21:03:27] <mrsun> oh
[21:03:53] <mrsun> gaah i need to sleep
[21:03:59] <mrsun> but cant ... stupid brain stupid brain
[21:04:04] <tjb1> Fastenal wanted $4 for 20 of them when I can get 100 for $4.75 at mcmaster so im trying to get a good order for mcmaster
[21:04:32] <jdh> there is an Ace hardware nearby that has a good selection of bolts various materials, metric also.
[21:04:55] <jdh> I get bulk stuff at fastenal pretty cheap.
[21:05:08] <jdh> but, the hardware store sells 100 of <whatever> pretty cheap usually
[21:05:53] <tjb1> ill check the hardware store
[21:05:56] <tjb1> I hate lowes
[21:06:07] <tjb1> They have the most random selection I have ever seen
[21:06:13] <jdh> they are useful for some stuff.
[21:06:16] <tjb1> They sell M3 bolts but not m3 nuts
[21:06:29] <jdh> I got some M3's from there, they sucked
[21:06:42] <jdh> crappy threads, like they were molded
[21:06:56] <tjb1> Yep nothing but junk
[21:07:03] <tjb1> I made this today :D -
http://sphotos-a.xx.fbcdn.net/hphotos-prn1/564051_4469257405520_1685339909_n.jpg
[21:07:04] <jdh> got perfect SS ones at the hardware store, 1/4 the price.
[21:07:43] <jdh> nifty. What material?
[21:09:56] <tjb1> all steel
[21:10:01] <tjb1> Thats the jack from a CB
[21:10:10] <tjb1> where the mic connects
[21:10:47] <jdh> I have those on my steppers
[21:11:18] <jdh> http://tinyurl.com/9nnracd
[21:11:27] <jdh> with my SS 3mm bolts holding the covers on.
[21:13:36] <tjb1> What size?
[21:13:38] <tjb1> nema23?
[21:14:41] <jdh> yeah, 570's
[21:15:15] <tjb1> Those are nice covers
[21:15:25] <jdh> yep. Connor made them for me.
[21:15:30] <tjb1> My wires werent in the little cover/bearing support correctly...
[21:15:36] <tjb1> You can see the wires
[21:15:46] <tjb1> I dont know if you know what i mean
[21:16:31] <jdh> no clue.
[21:16:43] <jdh> did you cut the brackets on the plasma?
[21:16:52] <jdh> what are the slots for?
[21:17:17] <tjb1> Yes
[21:17:20] <tjb1> Slot is for a wire tie
[21:17:25] <tjb1> zip tie
[21:17:53] <tjb1> Not sure what they are called to you
[21:18:01] <jdh> wire ties
[21:18:15] <tjb1> http://www.cncrouterparts.com/images/IMG_0520.JPG
[21:18:16] <tjb1> That
[21:18:51] <jdh> ?
[21:18:52] <tjb1> See where the cable comes out, there is a grommet there that fits the cable jacket...
[21:18:56] <jdh> that's not a wire tie.
[21:19:17] <tjb1> They made the wires too long so they stick out of hole
[21:19:53] <jdh> shove it back in!
[21:20:03] <jdh> I don't like the DB9
[21:20:08] <tjb1> I tried
[21:20:19] <tjb1> I took the cover off and I cant get it back in enough so the cable jacket is in
[21:20:35] <jdh> you took the cover off the motor?
[21:20:55] <Connor> You just kill 1/4 of the torque on it..
[21:20:58] <Connor> at least.
[21:21:12] <tjb1> Just that back coer
[21:21:13] <tjb1> cover
[21:22:04] <tjb1> Just the 1/2" high one where the wires go in
[21:22:54] <tjb1> How would that make it lose torque?
[21:22:56] <Connor> I've read your not suppose to disassemble steppers.. it kills the torque on them.. something about demagnetizing them and stuff.
[21:23:12] <jdh> only if you pull the rotor out
[21:23:22] <tjb1> I didnt take the armature out
[21:23:34] <Connor> Would think it would be the same taking the cover off, it could still touch the sides of the motor.
[21:23:54] <tjb1> All that cover has is a washer and a spring washer
[21:24:04] <tjb1> and the hole for the wires
[21:24:11] <Connor> not a bearing ?
[21:24:30] <tjb1> The bearing was still on the shaft
[21:25:51] <tjb1> Im not worried about it
[21:25:59] <tjb1> Just pisses me off they couldnt make them correctly
[21:26:19] <Connor> make what correctly ?
[21:27:09] <tjb1> So the jacket is in the grommet
[21:27:14] <jdh> get some black RTV and 'caulk' the gap
[21:28:41] <tjb1> Im not worried about the hole, I am worried about the stress on those wires
[21:28:51] <tjb1> But I taped the cable directly to the motor that that portion cant flex
[21:29:50] <tjb1> *motor so that
[21:30:53] <jdh> the rtv would act as a strain relief.
[21:32:16] <jdh> we replaced an ancient round slo-syn stepper yesterday. It had been there for 15 years? Ran off a full-step TBM-105 (huge) drive and the motor would burn you if you touched it.
[21:32:56] <jdh> the insulation on the wires had flaked off on the first half inch where it came out of the motor
[21:34:21] <tjb1> http://sphotos-b.xx.fbcdn.net/hphotos-ash3/530587_4469490131338_930172937_n.jpg
[21:34:31] <tjb1> http://sphotos-b.xx.fbcdn.net/hphotos-snc7/3444_4469494171439_930159285_n.jpg
[21:34:38] <tjb1> You can see the bracket in use in both of those
[21:34:43] <r00t4rd3d> http://www.instructables.com/id/Guino-Dashboard-for-your-Arduino/
[21:36:05] <jdh> http://www.wimb.net/sec_slosyn/img41/tbm105.jpg
[21:36:39] <jdh> that thing is 18" long. Drives a 2amp nema23 stepper
[21:41:35] <tjb1> Not very much power
[22:32:41] <tjb1> If water freezes in a pan, will it try to expand the pan?
[22:33:20] <ReadError> should go up
[22:35:20] <tjb1> We have 2 block heaters not in use…might put them in the water table and just let it freeze and plug them in when needing to use the table
[22:36:21] <tjb1> May just throw the sodium nitrite in it and say screw it
[22:36:24] <tjb1> Gonna die eventually
[23:04:30] <tjb1> Does linuxcnc take into account the motor acceration rates for doing something like a simultaneous XYZ move where the x or y or both are already moving and its needs to move the Z axis…will it slow the XY down until the Z has reached velocity?
[23:07:35] <jdh> it will make them be at the right place at the right time
[23:09:47] <tjb1> Ok thanks
