[01:57:49] <awallin> this would be nice for a small mill project
http://www.toolingmachine.biz/?21,engraving-spindles-motor-sp80-iso20-2400
[02:12:01] <archivist> awallin, did you see
http://www.dieselrc.com/projects/cncspindle/
[02:23:13] <awallin> nice. but no tool-changer :(
[02:23:54] <Jymmm> awallin: sure it does, just manual =)
[02:26:30] <archivist> mandraulic tool change
[03:15:24] <Loetmichel> mornin'
[06:14:02] <jthornton> jp_,
[06:31:32] <r00t4rd3d> wow after 3 months of fighting with Canon they finally give in
[06:32:08] <r00t4rd3d> paying for shipping and all :)
[06:32:22] <r00t4rd3d> all over a stupid Eye-Fi card
[06:58:23] <r00t4rd3d> and i got them to change their policy :D
[06:58:47] <r00t4rd3d> "We have issued a Service Notice about that as you suggested."
[07:00:10] <awallin> what's the wifi card good for? studio work?
[07:00:41] <r00t4rd3d> so you dont have to take the card out or plug the camera in to get the pics off
[07:01:17] <r00t4rd3d> just get near your router and the pics transfer to a set location
[07:02:31] <r00t4rd3d> i dont have a studio or anything
[07:03:23] <r00t4rd3d> im not even sure why i own a dslr
[07:03:49] <r00t4rd3d> i use my p/s more then anything
[07:30:13] <r00t4rd3d> http://techcrunch.com/2012/08/13/putting-an-end-to-the-biggest-lie-on-the-internet/
[07:30:24] <r00t4rd3d> finally someone does this
[07:31:29] <r00t4rd3d> http://tos-dr.info/
[07:42:58] <jp_> Jthornton: yes
[07:46:59] <jthornton> you see the timing belt with one belt glued down and one belt that goes over a pulley?
[07:47:11] <jthornton> no stretch
[07:47:26] <jp_> yes look at bell everman servo belt
[07:47:49] <jthornton> is that what you were talking about earlier?
[07:48:01] <jthornton> for your router belt?
[07:48:11] <jp_> yes and no thats one way to do it
[07:48:55] <jp_> my way was simpler im not convinced that cutting forces are that high for a belt
[07:49:24] <jthornton> what is your way?
[07:49:59] <jp_> just a simple loop and size the belt accordingly
[07:51:09] <jthornton> I used belts with the ends fixed and running under a roller then over the pulley then under another roller
[07:51:27] <jthornton> seems a loop would have double the stretch
[07:51:37] <jp_> it just frustrates me to hear it cant be done yet people forget that there using nema 23's to drive a router
[07:51:54] <jp_> yes it would
[07:51:58] <jthornton> only so much power there
[07:52:30] <jp_> my point exactly
[07:52:46] <jthornton> my belt drive is on a plasma and I should have went one size bigger on the Y axis I get vibration from the belt if the ways are not perfectly clean
[07:53:11] <jthornton> btw, I build automation equipment too
[07:53:15] <jp_> how do you like it?
[07:53:53] <jthornton> what?
[07:54:01] <jp_> i use timing belts all the time on servo axis and get excellent performance
[07:54:12] <jp_> How do you like your belt setup
[07:54:29] <jthornton> I like it, it does what I expected it to do
[07:55:25] <jthornton> http://s47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/
[07:55:47] <jthornton> that's how I built it
[07:56:14] <jp_> I actually replaced a festo $13000 linear motor with a servo and belt and got faster speeds and accels/decels
[07:56:52] <jthornton> yea linear motors are not very fast but they are accurate
[07:58:28] <jp_> yeah they also forgot to mention when the encoder gets damaged the whole motor needs to be replaced
[07:58:48] <jp_> wasn't happy
[07:59:09] <jthornton> I think the panasonics I use are the same way
[07:59:50] <jp_> nice setup on the plasma
[07:59:56] <jthornton> thanks
[08:00:27] <jp_> i think i will have to get back to work on mine once this 3d printer is done
[08:00:46] <r00t4rd3d> I hate when I give someone a stupid number on something I dont want to do and they take it.
[08:01:55] <archivist> profit!
[08:03:04] <r00t4rd3d> elaborate wedding sign.
[08:03:16] <jp_> jthornton: when you do gantrys in emc do you just take the command and send it to two septate stepgens?
[08:03:43] <jthornton> that's the easy way
[08:03:56] <jthornton> mine is driven by one motor and a jack shaft
[08:04:08] <jp_> ah
[08:04:23] <jthornton> or split one stepgen out to 4 pins
[08:04:58] <jp_> how do you like the 7i76?
[08:05:11] <jthornton> I like it a lot
[08:05:32] <jp_> just started to play with it so far so good
[09:34:03] <r00t4rd3d> http://www.kickstarter.com/projects/digistump/digispark-the-tiny-arduino-enabled-usb-dev-board
[09:34:21] <r00t4rd3d> i hate smd's but that is cool
[09:37:18] <jdh> what's to hate?
[09:40:45] <Jymmm> Whys does it say this?
[09:40:53] <Jymmm> https://gist.github.com/86816f8905ae6b3273ba
[10:36:19] <awallin> anyone used this?
http://ugracnc.com/ just found it, is that a new website/store ?
[10:43:13] <DJ9DJ> tag
[10:43:57] <Jymmm> DJ9DJ: WHACK!
[10:45:22] <DJ9DJ> hi Jymmmmmm
[10:45:29] <Jymmm> =)
[10:47:50] <r00t4rd3d> awallin, not new.
[10:48:08] <r00t4rd3d> ive gotten some things off there ebay store
[10:48:17] <r00t4rd3d> limit switches
[10:49:38] <r00t4rd3d> http://www.ebay.com/sch/*www.ugracnc.com*/m.html?_nkw=&_armrs=1&_from=&_ipg=25&_trksid=p3984.m1439.l2654
[10:49:46] <r00t4rd3d> their ebay stuff
[12:00:29] <Jymmm> "Blue Bag Policy", my only question is how do you use/hold the blue bag, drop trough, do your business, when hanging hundreds of feet off the ground on the side of a cliff/mountain?
http://www.nps.gov/olym/planyourvisit/wilderness-sanitation.htm
[12:17:41] <JT-Shop> that's what buddies are for...
[12:19:26] <IchGuckLive> hi all
[12:34:28] <jp_> JT-Shop: heres my router gantry
https://picasaweb.google.com/103502607515689372041/LinuxcncStuff#5776580329666349778
[12:35:28] <jthornton> he went to take a nap... nice gantry with linear rails and all
[12:35:36] <IchGuckLive> ip_ liniar only on forground or also back
[12:36:08] <jp_> only on front dont need them on back
[12:36:32] <IchGuckLive> ball spindle ?
[12:36:44] <skunkworks> question linux related... Is it possibel for linux to change the tmp directory permissions when the volume runs out of space?
[12:37:24] <IchGuckLive> ip_ 2 steppers for X
[12:38:44] <IchGuckLive> movement on Rack liniar Gear
[12:40:13] <jp_> nope plan on using belts
[12:40:40] <IchGuckLive> X-size
[12:41:18] <jp_> i have material for 10 ft if i want but probably just 8
[12:41:38] <IchGuckLive> Why not trapezional on 4mm tread this gives you a very accuracy at 400steps and lots of speed
[12:42:19] <IchGuckLive> necouse imperial first
[12:43:25] <jp_> ill probably go metric just have lots of imperial laying around
[12:43:37] <IchGuckLive> B)
[12:44:20] <IchGuckLive> the tread leadscrew and nut is so cheep here also Ballscrews drop in price rapidly but only 5mm thread
[12:52:08] <L84Supper> tzerslotten? T-nuten?
[12:54:38] <L84Supper> skunkworks, I could see writing script to check on the space left in the temp dir and then having it change the permissions at some trip point
[12:55:42] <archivist> you need more than permissions fixing when running out of space
[12:56:09] <L84Supper> yeah, I'm not sure what he's actually trying to end up doing
[12:56:35] <skunkworks> Thanks.. We had a server that we don't manage where the apache error_log file filled up the drive (140gb) after fixing that - the timp file permissions needed to be fixed also.
[12:56:48] <skunkworks> *tmp
[12:57:09] <archivist> my initiation to disk full was the messages to root filling up what little was left!
[12:57:58] <archivist> making logging in specially hard to scrub some
[12:58:04] <L84Supper> I've been stung by similar issues, updates that fill up the tmp or similar
[12:59:41] <archivist> skunkworks, are you on some vm/whatever where they borked the permissions when getting full, complain
[13:00:03] <skunkworks> The company that set it up made some snide remark that we must have been playing with the permissions. (but honestly - we don't touch it)
[13:00:15] <skunkworks> No VM
[13:00:42] <skunkworks> we did figure out what was causing the space issue though.
[13:00:52] <archivist> Ive never heard of /tmp having problems like that
[13:01:02] <skunkworks> Neither does google.
[13:01:13] <skunkworks> whatever - fixed now I guess
[13:01:31] <archivist> seen some stupid attempts by some admins at controlling users though
[13:01:54] <archivist> poor use of quotas being one
[13:02:01] <skunkworks> heh
[13:04:04] <L84Supper> http://www.youtube.com/watch?feature=player_embedded&v=4HOi6Az531A Metal Laser Sintering Hybrid Milling Machine, looks like I'll have to make my own if I need >250mm travel
[13:12:29] <IchGuckLive> L84Supper: not a good stategy for the layers
[13:13:26] <IchGuckLive> you can see this at the expo in Germany this year 2 tiimes in Stutgard and frankfurt
[13:18:56] <IchGuckLive> ls -l
[13:19:00] <L84Supper> IchGuckLive, whats not good about it?
[13:19:51] <IchGuckLive> i see the futher video shows a better one for the circle so i guess they rough in lines and then harden out in shape
[13:22:16] <L84Supper> photopolymers + metal + mill is what I need
[14:36:46] <JT-Shop> does a rotary axis break the naive cam dectector?
[14:53:39] <micges> JT-Shop: yes
[15:04:56] <JT-Shop> I have a guy with a 3 axis machine X Z and A any tips to use for that setup in coordinated motion?
[15:05:36] <jp_> what control
[15:06:17] <JT-Shop> EMC
[15:06:43] <jp_> what is it a lathe
[15:07:28] <JT-Shop> a weird machine like a mill but no Y axis and A is in line with X
[15:09:03] <micges> what is the problem?
[15:09:50] <JT-Shop> the machine speeds up and down, I think the Z axis is slow
[15:12:55] <JT-Shop> at first I told him to use G64 Pn but got to thinking that the rotary my break that but now he says that it helped
[15:14:40] <JT-Shop> I see his max acceleraton on X is 5 and Z is 1 so that might be the problem
[15:14:42] <micges> probably when he use A axis then all axis slow down
[15:15:04] <JT-Shop> I think the A is moving all the time
[15:15:05] <micges> yes it could be also
[15:17:35] <archivist> often recommended to use inverse time mode
[15:21:37] <archivist> just trying an experiment, latency-test during a system update
[15:22:31] <JT-Shop> he is using G94, there is a combination of X Z and A moves on each line of the sample code I have here
[15:23:20] <JT-Shop> I don't know if his CAM software can properly calculate the F for inverse time mode
[15:24:24] <archivist> the rotary currently has no clue of radius and correct F using the normal mode
[15:24:45] <archivist> feature :(
[15:25:26] <cradek> he's probably misunderstanding how F works
[15:25:55] <JT-Shop> hows that?
[15:26:04] <archivist> I wonder if the css for a lathe could be show horned in
[15:26:11] <archivist> shoe
[15:26:28] <cradek> http://www.linuxcnc.org/docs/html/gcode/machining_center.html#sub:feed-rate
[15:28:06] <JT-Shop> with an X Z and A move on every line the A should move to the end point at a speed to keep up with X and Z right?
[15:28:58] <cradek> you say an A *move* on every line. do you actually mean an A *word* on every line?
[15:29:15] <JT-Shop> yes
[15:29:19] <JT-Shop> X0.511 Z-0.1355 A4.12 F20.5
[15:29:22] <cradek> it's moves that are important, not the presence or absence of words
[15:29:28] <JT-Shop> X0.4772 Z-0.1329 A3.81
[15:29:45] <JT-Shop> every line the A is different
[15:30:42] <cradek> ok in G94 that means the XZ-only line is requested to be at 20.5 inches/minute
[15:30:56] <cradek> but it sure may be slower to wait for A
[15:31:40] <JT-Shop> and if A is not the slow one it will just keep up?
[15:32:17] <cradek> for this gcode to work right (assuming you want constant cutter-to-workpiece velocity) I'd expect a different F word for every line, whether in inverse mode or not
[15:32:44] <cradek> feed is obviously tricky in this situation
[15:33:19] <cradek> yes if A is infinitely fast you'll get your 20.5 in the XZ plane and A will follow it at whatever speed necessary to stay coordinated
[15:34:21] <cradek> like archivist says, 5 axis cam always generates G93 code for this reason
[15:35:01] <JT-Shop> I think I'm understanding now
[15:35:48] <cradek> if the A axis is a worm he might be able to set the accel VERY high
[15:36:20] <JT-Shop> its 4 times faster than the X now
[15:36:33] <cradek> only 4??? you know it's in degrees right?
[15:37:09] <JT-Shop> yes, but didn't take degrees into account
[15:37:34] <JT-Shop> degrees per second right?
[15:37:50] <JT-Shop> for max velocity?
[15:38:00] <cradek> most machines will have MANY more (steps or counts)/inch than /degree, so scale on rotaries will look very low and vel/acc will look very high
[15:38:03] <cradek> yes
[15:38:43] <JT-Shop> yes scale is 1/10 of the X
[15:39:25] <cradek> he may have his vel/acc really wrong then
[15:39:39] <JT-Shop> thanks
[15:39:48] <cradek> that will sure make it worse, but I still suspect gcode feed rate problem too
[15:39:51] <cradek> welcome
[15:40:07] <JT-Shop> I'll pass all this on to him
[15:54:17] <DJ9DJ> gn8
[16:23:30] <Tom_itx> JT-Shop, tried a couple things for static ip today with no luck so far
[16:23:32] <Tom_itx> http://askubuntu.com/questions/4826/switching-a-server-to-static-ip-from-dhcp
[16:23:34] <Tom_itx> was one
[16:24:23] <atom1> /usr/share/doc/network-manager/README.Debian
[16:24:27] <atom1> was another one
[16:25:08] <Tom_itx> still haven't found the magic file
[16:28:20] <Tom_itx> the first time i tried the ifdown eth0 it said it wasn't configured yet however it had a dynamic ip assigned to it and displayed it with ifconfig
[16:31:30] <archivist> Tom_itx, I just use the graphical ip setting, it just worksforme has this changed with later versions
[16:31:49] <Tom_itx> where would that be found?
[16:32:00] <Tom_itx> 10.04 live cd install
[16:32:14] <Tom_itx> i think i've been thru them but may have missed something
[16:32:22] <archivist> system/administration/network
[16:32:49] <atom1> i have network tools
[16:32:59] <archivist> wired connection/properties
[16:33:58] <archivist> unclick roaming, set some sensible ip and mask numbers
[16:34:35] <atom1> i'm not finding that
[16:34:40] <archivist> and set the drop down to fixed ip
[16:34:42] <atom1> in network tools
[16:34:57] <atom1> i pulled up ethernet eth0
[16:35:02] <atom1> under devices
[16:35:37] <atom1> but haven't found a place to edit it
[16:37:17] <atom1> ok i may have it here
[16:37:33] <atom1> under IPv4 ?
[16:38:04] <archivist> mine is older so only ipv4 here
[16:38:20] <atom1> looks like it's the same under 10.04
[16:38:26] <atom1> i'll give this a try
[16:39:18] <archivist> its the first job I do when I fire up a new box to get connected as I only run fixed ip here
[16:39:34] <archivist> I hates dhcp
[16:39:37] <atom1> i wonder why it keeps ignoring the interfaces file
[16:39:57] <atom1> ok, i'll reboot and see how it comes up
[16:41:50] <Tom_itx> it still came up under dhcp
[16:44:57] <Tom_itx> what's that program name? maybe i can sudo run it in a terminal
[16:45:09] <Tom_itx> it never asks for admin password
[16:45:27] <archivist> you unlock it
[16:45:34] <archivist> then it asks
[16:46:10] <atom1> i don't see a place to do that
[16:47:46] <Tom_itx> i'll look it over after bit. supper is calling me
[16:48:32] <archivist> are you using network from system administration NOT network tools
[16:48:45] <archivist> bed is calling me
[16:49:19] <archivist> and the other box running ./configure
[16:49:28] <Jymmm> who would use SS shim stock typically?
[16:49:43] <Jymmm> 0.015"
[16:49:55] <Jymmm> 0.010 - 0.015"
[16:50:49] <Tom_itx> archivist yes
[16:50:56] <Jymmm> I want to pick up a piece of scrap before buying a whole roll.
[16:50:57] <Tom_itx> thanks.. i'll work on it this evening
[16:51:10] <Tom_itx> Jymmm get a friggin feeler gage
[16:51:13] <Tom_itx> dammit!
[16:51:23] <Jymmm> Tom_itx: 2sf
[16:53:40] <JT-Shop> maintenance men Jymmm
[16:54:18] <Jymmm> JT-Shop: what would be the application?
[16:54:49] <JT-Shop> shimming up machinery to line up shafts and such
[16:56:07] <Jymmm> JT-Shop: so no fabricator I could buy a couple of sq ft scrap from?
[16:56:14] <Jymmm> maybe titanium too
[16:56:26] <Jymmm> I just dont know what idustries use them
[16:56:29] <Jymmm> industries
[16:57:28] <JT-Shop> only if he makes things that need shimming up like skid mounted motor/pump etc
[16:58:40] <syyl> tool/die guys have also shim stock availible
[16:59:05] <syyl> almost every mechanic guy Oo
[17:01:18] <archivist_hobbin> xchat installed and tested :)
[17:04:42] <JT-Shop> an authentic Great Plains Indian Dreamcatcher (made in china)
[17:06:57] <archivist> latency-test stopped updating during the upgrade of the other box
[17:07:56] <archivist> was the fresh install upgrade of the livecd :)
[17:10:42] <archivist> is it worth adding to the latency-test docs that abuse does not include upgrading the os
[17:18:13] <atom1> archivist, all i have under system administration is network tools and under system preferences there is network connections
[17:18:37] <atom1> the latter is where i was adding a static ip but it didn't appear to take
[17:27:20] <archivist> I wonder why I prefer 8.04 :)
[17:31:09] <Tom_itx> heh
[17:31:22] <Tom_itx> i'm still looking it over
[17:33:28] <Tom_itx> under IPv4 the options i have are automatic DHCP, automatic DHCP addresses only, Manual, Shared to other computers
[17:33:40] <Tom_itx> i'm guessing manual is what i'm after
[17:37:40] <Tom_itx> http://tom-itx.dyndns.org:82/
[17:38:00] <Tom_itx> ok JT-Shop
[17:38:14] <Tom_itx> that's where you edit the ip
[17:54:41] <JT-Shop> yo
[17:55:10] <JT-Shop> hey I have a web site just like that
[17:57:10] <Tom_itx> change the ip from the menu
[17:57:41] <Tom_itx> system -> preferences -> network connections
[17:58:42] <Tom_itx> edit eth0 IPv4 settings to manual and enter the info there
[17:59:40] <JT-Shop> ok
[18:00:09] <Tom_itx> i still don't know why it ignores the interfaces file
[18:02:16] <JT-Shop> http://184.63.140.99:81/public/BP-Conversion/
[18:03:13] <Tom_itx> is that static now?
[18:03:24] <Tom_itx> no, that ip isn't
[18:03:34] <Tom_itx> that's why you wanna use dyndns
[18:03:41] <JT-Shop> yea but set in the router to be static
[18:04:20] <Tom_itx> the outbound one?
[18:04:47] <Tom_itx> your local 192.168.... can be but is the outbound one?
[18:04:48] <JT-Shop> yea
[18:05:52] <Tom_itx> you might wanna shrink those
[18:06:25] <JT-Shop> yea, just installing gimp now
[18:06:37] <JT-Shop> last one is the 7i77 installed
[18:06:41] <Tom_itx> 2 and 3 aren't visible
[18:07:21] <JT-Shop> i just deleted a couple so refresh
[18:07:27] <Tom_itx> 324 & 325 not found
[18:07:37] <elmo40> JT-Shop: what is the large capacitor for? filtering DC power?
[18:08:04] <Tom_itx> that or zapping your tongue
[18:08:24] <elmo40> nothing like a good sizzle every now and then ;)
[18:08:27] <JT-Shop> that's one of the three parts of the power supply for the drives
[18:09:33] <elmo40> is this for steppers?
[18:10:17] <Tom_itx> so you run the db25 out the pc to the 7i77 from the 5i25
[18:10:31] <Tom_itx> or is your pc inside a control box?
[18:11:06] <elmo40> I like the large cables on the lower right :)
[18:11:11] <JT-Shop> atm the pc is sitting on the rear electrical cabinet
[18:11:13] <elmo40> screw on connectors?
[18:11:25] <JT-Shop> mil connectors
[18:11:41] <elmo40> have built in shielding, I take it
[18:12:49] <Tom_itx> i rewired all my stuff using shielded cable
[18:12:53] <Tom_itx> it helps
[18:13:22] <JT-Shop> ok refresh I rotated and made them smaller
[18:13:49] <JT-Shop> I assume at this point the pc will be on top of or inside that cabinet
[18:14:16] <JT-Shop> most of the stuff on the lower left will go, the vertical cards are the drives and they stay
[18:15:05] <JT-Shop> look at all the M3 stand offs in 26
[18:15:09] <Tom_itx> what do those relays do?
[18:15:24] <JT-Shop> on the board?
[18:15:30] <Tom_itx> yeah
[18:15:36] <Tom_itx> psu?
[18:15:48] <Tom_itx> there's a couple mov's on there too
[18:15:50] <JT-Shop> one is for power supply for the drive
[18:15:58] <JT-Shop> mov?
[18:16:05] <Tom_itx> the red disks
[18:16:14] <JT-Shop> oh
[18:16:27] <JT-Shop> I thought they were caps
[18:16:34] <Tom_itx> i doubt it
[18:16:50] <Tom_itx> they might be but those are usually baby poo brown
[18:17:00] <JT-Shop> ah ok
[18:17:35] <Tom_itx> surge clamps
[18:17:55] <Tom_itx> open your surege strip and you'll find some more
[18:18:01] <Tom_itx> along with some chokes etc
[18:18:56] <JT-Shop> I was just thinking I'd put a SSR in there to turn on the power supply controlled by the 7i77
[18:19:05] <JT-Shop> drive enable
[18:23:02] <JT-Shop> the only thing left to sort out is where the encoders get the 5v from
[18:23:27] <Tom_itx> get a little smps like i did
[18:23:39] <Tom_itx> it will take like 35v input
[18:23:42] <Tom_itx> i forget exactly
[18:23:56] <JT-Shop> got a link?
[18:24:04] <JT-Shop> the power supply is 120v
[18:24:16] <Tom_itx> no DC lower than that?
[18:24:35] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/misc_stuff/5v_switcher.jpg
[18:24:40] <Tom_itx> those are what i used
[18:24:42] <JT-Shop> 24v on field power
[18:24:48] <Tom_itx> i could send ya one if you want
[18:24:55] <Tom_itx> i took the input cap off
[18:25:02] <Tom_itx> since it's only rated for 16v
[18:25:03] <JT-Shop> tiny little buggers
[18:25:14] <Tom_itx> good for like 2.5 - 3 A
[18:25:33] <JT-Shop> it only switches 16v?
[18:25:43] <Tom_itx> no it's a 5v reg
[18:25:59] <Tom_itx> but i made it for something else and only needed 16v caps on the input
[18:26:06] <JT-Shop> all my stuff is 24v on the coil side
[18:26:09] <Tom_itx> the input on yours will be filtered anyway
[18:26:12] <Tom_itx> that's fine
[18:26:19] <Tom_itx> mine is 25v input
[18:26:37] <JT-Shop> and it will switch 120vac?
[18:26:41] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/control5.jpg
[18:26:51] <Tom_itx> you can see it just left of the mesa cards
[18:26:59] <Tom_itx> no it needs DC in
[18:27:07] <Tom_itx> lemme find the data sheet
[18:27:13] <jdh> http://www.mpja.com/5V-4A-Desktop-Supply-Cisco/productinfo/18464+PS/
[18:27:23] <JT-Shop> I had to squint to see it lol
[18:28:04] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/misc_stuff/switcher.png
[18:28:07] <Tom_itx> there's the schematic
[18:30:05] <Tom_itx> max supply voltage 45v
[18:30:21] <Tom_itx> http://www.ti.com/lit/ds/symlink/lm2596.pdf
[18:30:53] <JT-Shop> I'll just stick to the SSR's I have laying about
[18:31:00] <JT-Shop> thanks for the offer
[18:31:06] <Tom_itx> np
[18:31:23] <Tom_itx> i could have put it on my main supply but didn't want to push the limit on it
[18:31:33] <Tom_itx> so i put a cap on the centertap with a diode
[18:31:42] <Tom_itx> and got 25v for it
[18:31:59] <Tom_itx> that's what the cap by itself in the box is for
[18:34:16] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/misc_stuff/board3.jpg
[18:34:20] <Tom_itx> that was the prototype
[18:35:12] <JT-Shop> your a wiz at that stuff and I struggle with it like understanding inverse time mode lolo
[18:36:14] <Tom_itx> they give you the design layout
[18:36:25] <Tom_itx> and what parts to use
[18:36:31] <JT-Shop> that helps
[18:38:10] <Tom_itx> most of those mfg have a design page
[18:38:36] <JT-Shop> yea, but you have to know a little about what your looking at to make sense of it all
[18:39:16] <Tom_itx> i should put a few more of those together
[18:39:24] <Tom_itx> i dunno how many boards i have
[18:46:04] <elmo40> I might be buying an SL-3 mori seiki for $500
http://www.kgimachinetool.com/images/machines/SL3-002.jpg
[18:46:34] <Tom_itx> you couldn't hardly go wrong for that
[18:46:38] <Tom_itx> if you can move it
[18:46:54] <Tom_itx> chip conveyor n all
[18:48:27] <asdfasd> anyone good in swich mode power supply?
[18:50:43] <JT-Shop> sop is to just ask your question here
[18:52:22] <Tom_itx> elmo40 does it come with a bar feed for that :)
[18:53:23] <asdfasd> just modified PC power supply for something else, there is an inductor between the diode rectifier and output capacitor, and that inductor is heating too much, Im not sure wire or core, how to reduce that heat
[18:54:25] <JT-Shop> elmo40: is that a hydrolic chuck?
[18:54:57] <JT-Shop> hydraulic
[18:56:10] <JT-Shop> Tom_itx: isn't there an electronics channel of some sort?
[18:56:15] <Tom_itx> asdfasd i dunno if this will help or not:
http://www.wikihow.com/Convert-a-Computer-ATX-Power-Supply-to-a-Lab-Power-Supply
[18:56:27] <Tom_itx> JT-Shop yes but ##electronics is sh**
[18:56:39] <JT-Shop> ah ok
[18:56:45] <Tom_itx> you can get answers a couple other place like #robotics or #seattlerobotics
[18:56:51] <Tom_itx> possibly #avr
[18:57:31] <Tom_itx> asdfasd too much heat may mean too much load
[18:58:00] <r00t4rd3d> lol
[18:59:11] <Tom_itx> JT-Shop you may get an answer in ##electronics if you happen in when they're OT but generally they're not
[18:59:36] <asdfasd> I did something similar as in this project, but the load is well below the rated, the PC psus are just tuu much over rated
[19:00:40] <asdfasd> rated at 22A, I do continuous load at 10A and only that inductor is heating
[19:01:13] <asdfasd> I tried 2 wires in prallel still heating the same
[19:22:46] <elmo40> Tom_itx: no chip conveyor :(
[19:23:21] <r00t4rd3d> arduino powered mech warrior:
[19:23:22] <r00t4rd3d> http://imgur.com/a/NKUI3
[19:23:26] <elmo40> JT-Shop: yes, hydraulic 3-jaw
[19:23:49] <Tom_itx> can you get jaws for it?
[19:23:54] <Tom_itx> that's always handy
[19:24:01] <r00t4rd3d> "Quadrupedal Mech"
[19:24:08] <elmo40> add a sink to the diode
[19:24:29] <elmo40> eBay has a conveyor for the SL-3, $600 :-P
[19:24:38] <Tom_itx> heh
[19:25:09] <Tom_itx> make a tray to fit inside
[19:25:29] <Tom_itx> lathe shavings are stringy anyway usually
[19:25:39] <Tom_itx> clog up the chip conveyor
[19:26:40] <elmo40> this one is very similar, though it has 6-tool locations, I believe this one only has 5
http://qurl.org/MV1
[19:27:51] <Tom_itx> so what's wrong with it?
[20:43:22] <Jymmm> At what temps does SS anneal?
[20:44:04] <r00t4rd3d> guess 1200f
[20:44:21] <r00t4rd3d> not sure what anneal means though
[20:46:33] <mozmck> soften
[20:47:18] <Tom_itx> what type of stainless?
[20:47:37] <Jymmm> 304 302
[20:47:52] <Tom_itx> 304 316 430?
[20:48:38] <Tom_itx> http://www.aksteel.com/pdf/markets_products/stainless/austenitic/304_304L_Data_Sheet.pdf
[20:49:16] <Jymmm> Tom_itx: got one for 316 too?
[20:49:27] <Tom_itx> Annealing: Heat to 1900 - 2050°F
[20:49:27] <Tom_itx> (1038 - 1121°C), then cool rapidly.
[20:51:31] <Jymmm> Tom_itx: got a datasheet for 316 too?
[20:51:53] <Tom_itx> http://www.askzn.co.za/tech/tech_grade_316.htm
[20:52:11] <Tom_itx> Heat from 1 010oC to 1 120oC and cool rapidly in air or water. The best corrosion
[20:52:11] <Tom_itx> resistance is obtained when the final annealing temperature is above 1 070oC.
[20:52:50] <Tom_itx> heat treat isn't always a temp, rather a process
[20:54:22] <Jymmm> I'm more interested in the characteristics when it's exposed to 1200F+ for 20+ minutes.
[20:55:16] <Tom_itx> what is that high temp stainless sons of guns used in that cannon sized flame thrower?
[20:55:20] <Tom_itx> you should find that out
[20:55:40] <Tom_itx> that's the metalurgy you're looking for
[20:56:46] <Jymmm> that 316 link looks about right and it's already annealed
[20:57:10] <Valen> stainless generally only work hardens and even then only sometimes
[20:57:32] <Valen> do keep in mind behaviour at temperature would be different to cooled after aneling
[20:57:41] <Jymmm> Valen: I'm concerned about it softening, not hardening =)
[20:58:12] <Tom_itx> maybe you should email one of the suppliers
[20:58:23] <Tom_itx> http://www.askzn.co.za/tech/tech_selection.htm
[20:58:37] <Valen> there are curves for things like UTS vs temperature, people use it to make rockets with
[21:00:56] <r00t4rd3d> north korea?
[21:01:55] <Valen> not quite
[21:02:09] <Valen> armadillo aerospace and a bunch of other "new space" groups
[21:05:02] <r00t4rd3d> that sounds korean
[21:05:16] <r00t4rd3d> armadillo aerospace
[21:05:30] <r00t4rd3d> armadillo's dont fly!
[21:06:11] <Tom_itx> Jymmm you know they use foil for heat treat process too?
[21:06:19] <Tom_itx> wrap metals in ss foil
[21:06:35] <Jymmm> yeah, I have some
[21:06:44] <Jymmm> 0.002 ss tool wrap
[21:06:46] <Tom_itx> http://www.finishing.com/125/45.shtml
[21:06:54] <Tom_itx> that might have something of interest. who knows
[21:10:10] <elmo40> Tom_itx: what is wrong with the SL-3? It spins. X&Z moves.
[21:10:11] <tjb1> zDo you guys also put paper in the stainless bags?
[21:10:25] <elmo40> but when you want to run a program it either spins or x&z move, not both :-P
[21:10:40] <Tom_itx> good conversion machine
[21:11:23] <tjb1> We put scraps of paper in to burn the oxygen off
[21:12:01] <elmo40> Tom_itx: my thoughts exactly :)
[21:12:14] <Jymmm> tjb1: "but but but the burning paper might get too hot and melt the tool!!!"
[21:12:29] <tjb1> I forgot about that Jymmm
[21:12:29] <elmo40> everything works, just not all together :-P
[21:12:42] <tjb1> I have opened the bags to random shapes of metal before
[21:13:13] <Jymmm> heh
[21:13:37] <tjb1> Im not a fan of carburizing
[21:15:12] <Jymmm> tjb1: rather parkerize instead?
[21:15:36] <tjb1> Never done that
[21:16:28] <Jymmm> tjb1: Step 1) Get acid to a rolling boil.
[21:16:51] <tjb1> 2) dunk face in acid?
[21:17:06] <Jymmm> 2) run like hell =)
[21:18:13] <Jymmm> Phosphating, better known as "Parkerizing", is a process involving the transformation of the surface of the steel to a rust resistant manganese or zinc phosphate. Modern chemicals for phosphating are far superior to their predecessors. Phosphating is a non-reflective, matte black finish that resists corrosion and abrasion. The coating has a sponge-like structure that entraps oil or other corrosion resistant solutions producing an excellent
[21:18:14] <Jymmm> coating for firearms exposed to high humidity and/or harsh environments. Phosphating will hide light scratches, pitting or blemishes.
[21:19:26] <Tom_itx> black chrome?
[21:19:55] <Jymmm> http://www.robarguns.com/additional_finishes.htm
[21:21:35] <Valen> ceramic coating
[21:22:31] <jdh> duracoat
[21:22:40] <Valen> sounds like the stuff
[21:23:36] <Valen> www.cerakoteguncoatings.com was the other one i knew of
[21:25:27] <alex4nder> we making guns?
[21:25:47] <r00t4rd3d> i want too
[21:25:50] <Tom_itx> Jymmm is giving us a lesson in metalurgy
[21:26:28] <Valen> armadillo aerospace is owned by the john carmack
[21:26:37] <Valen> of ID/doom/quake fame
[21:27:06] <alex4nder> r00t4rd3d: you're the wooden-gun master
[21:31:03] <r00t4rd3d> i want to make a ar receiver
[21:31:20] <alex4nder> it's pretty easy to start from an 80% forging
[21:31:47] <r00t4rd3d> out of aluminum
[21:32:11] <alex4nder> yes
[21:32:17] <r00t4rd3d> http://www.cncguns.com/
[21:32:35] <alex4nder> there are people in this channel who have made them.
[21:33:04] <r00t4rd3d> did they go on a shooting spree?
[21:33:10] <alex4nder> I don't think so.
[21:33:15] <r00t4rd3d> aww
[21:33:45] <r00t4rd3d> thats the cool thing to do in America now
[21:34:02] <alex4nder> please, Norway has us beat for recent shootings.
[21:34:44] <r00t4rd3d> im not a gun person, just would be cool to be able to make one
[21:37:00] <jdh> how much is an 80% receiver?
[21:37:31] <alex4nder> jdh: depends.. $75 last I bought
[21:37:32] <r00t4rd3d> http://i.imgur.com/VCZWD.jpg
[21:37:34] <r00t4rd3d> $50
[21:37:54] <alex4nder> r00t4rd3d: for an 80%?
[21:38:03] <r00t4rd3d> no for that sign in the image i posted
[21:38:05] <alex4nder> jdh:
http://www.tacticalmachining.com/80-products/80-receivers/80-ar-15-lower-receiver.html <- I've bought from these guys
[21:38:14] <alex4nder> r00t4rd3d: nice
[21:38:20] <jdh> $89 for a 100% (stripped)
[21:38:34] <r00t4rd3d> i can get a stripper for 10 bucks
[21:38:56] <alex4nder> jdh: some of us in certain states have trouble moving stripped lower receivers intended for pistols past the authorities.
[21:38:57] <jdh> you can get a blowjob for $10 too, but you might not like him.
[21:39:28] <jdh> never had the urge for an ar pistol
[21:39:41] <jdh> I did see .308 somewhere the other day though.
[21:39:59] <alex4nder> owning an AR pistol helps if you're building rifles with 14.5" barrels and permanently attached flash hiders
[21:40:11] <alex4nder> because it gets around the whole constructive-possession felony thing
[21:40:59] <r00t4rd3d> so even if i make an illegal gun its still illegal?
[21:40:59] <jdh> but then it is a pistol, and can't have a stock
[21:41:19] <alex4nder> r00t4rd3d: 14.5" barrels with permanently attach flash hiders that bring them out to 16" are legal.
[21:41:45] <alex4nder> jdh: the pistol receiver is there as a prop
[21:41:46] <r00t4rd3d> even a fully auto ar15?
[21:41:58] <alex4nder> if you own a legal fully auto gun, yes
[21:42:04] <jdh> guy at work has a 12" one, with a supressor
[21:42:09] <alex4nder> yah, that's an SBR
[21:42:15] <alex4nder> which is a different story
[21:42:30] <alex4nder> "normal people" in california have a really hard time owning SBRs (i.e. they can't)
[21:42:36] <jdh> and quite a few others in various oddball calibers
[21:42:49] <r00t4rd3d> you can goto walmart here and buy an ak47
[21:43:00] <jdh> mine doesn't sell AK's
[21:43:13] <r00t4rd3d> well its not redneck enough then
[21:43:16] <r00t4rd3d> file a complaint
[21:44:41] <jdh> I could use an upper.
[21:45:15] <alex4nder> yah
[21:45:31] <jdh> it is more difficult than I thought to find someones takeoff for aa reasonable price
[21:45:42] <alex4nder> what do you mean?
[21:45:48] <alex4nder> what's 'reasonable'?
[21:45:58] <jdh> $300 with bcg/handle
[21:46:06] <alex4nder> oh, well you can get some bullshit for that
[21:46:10] <alex4nder> but $300 is the cost of a good barrel
[21:46:53] <jdh> if you were snobbier, you would say $600
[21:47:17] <alex4nder> nah, I said 'good', not 'great'
[21:47:39] <alex4nder> I can't shoot for shit; calling me a snob gives me too much credit.
[21:47:47] <jdh> I' be fine with non-rusty :)
[21:47:55] <alex4nder> oh, well you can find that
[21:48:16] <alex4nder> I guess it just depends
[21:48:30] <alex4nder> I just sold a really nice bravo company upper on a pretty basic lower for $800
[21:49:29] <Valen> I want one of these
http://www.youtube.com/watch?feature=player_detailpage&v=7ft2j6J4NcY#t=47s
[21:49:40] <alex4nder> fear
[21:51:44] <alex4nder> jdh:
http://www.del-ton.com/AR_15_Barrel_Assembly_p/dt1014.htm <- that's new.. I've seen them sell for $375 in groupbuys
[21:51:46] <Valen> i figure if i'm shooting at somebody i want them to damn well stay shot
[21:52:02] <alex4nder> Valen: until they get close enough to you to kill you with a rock
[21:52:21] <Valen> if they are that close your doin it wrong ;-P
[21:52:47] <jdh> alex4nder: yeah, they are (relatively) local.
