[01:52:58] <LawrenceG> ok
[01:53:08] <tomp2> :-[
[03:52:53] <JymmmEMC> LawrenceG: how are you connecting the SSR's to the paraport?
[04:03:46] <LawrenceG> JymmmEMC: using homebrew breakout board.. port -> 74ac245 -> SSR
[04:27:04] <tomp> Hugomatic: re: svg to gcode, the open source svg engines should have the interpolation. look at inkscape & apache's batik
[04:31:41] <tomp> and many of the tokens , format, and even some of the math are here http://wiki.svg.org/Path#B.C3.A9zier_theory
[04:35:54] <tomp> heh, Don Lancaster evn has a lot of good code for this http://www.tinaja.com/cubic01.asp ( Don Lancaster: author of 'the idiot bastard son of op amp cookbook')
[04:57:09] <jmkasunich> damn... when you ream a hole with a 1/2" reamer, it's not supposed to come out 0.504
[04:58:53] <cradek> ouch
[04:59:24] <jmkasunich> the timing belt pulleys that came with the shoptask were bored 3/8", for standard NEMA 34 steppers
[04:59:30] <cradek> good thing you really meant it to be 17/32 right?
[04:59:33] <jmkasunich> my steppers have half inch shafts
[04:59:43] <cradek> dang
[05:00:27] <jmkasunich> so far I've bored and reamed one of the three
[05:00:54] <cradek> can you just bore the others to size?
[05:01:01] <jmkasunich> not really
[05:01:16] <jmkasunich> this steel machines for shit, can't get a decent finish with a boring bar
[05:01:37] <jmkasunich> (crappy chinese pulleys, they almost look like the teeth were cut with a hacksaw
[05:02:41] <jmkasunich> my reamer has 5 flutes, so I can't really check its diameter
[05:02:54] <cradek> did it rattle or squeak when you reamed it or did it seem right?
[05:03:05] <jmkasunich> it seemed reasonable
[05:03:10] <jmkasunich> no chatter
[05:03:14] <cradek> ream some scrap I guess
[05:04:15] <jmkasunich> this isn't a typical machine reamer (surplus, like most of my tooking)
[05:04:40] <jmkasunich> it has a long lead-in taper, from about 1/4" to 1/2" over two inches
[05:05:00] <cradek> weird
[05:05:36] <cradek> is it loose in the .504 hole now?
[05:05:41] <jmkasunich> yeah
[05:06:05] <cradek> dangit that's frustrating
[05:06:55] <cradek> I hear you can make a decent reamer by rounding the cutting edges of a good drill bit (like bullnose)
[05:07:01] <cradek> I haven't tried it yet
[05:10:54] <jmkasunich> replacement pulleys are ~$10 each, so its not the end of the world
[05:11:13] <jmkasunich> (even the replacements will need bored though, they don't have 1/2" as stock)
[05:12:36] <jmkasunich> hmm, my reamer is what is known as a construction reamer
[05:12:47] <jmkasunich> I bet it reams a few thou oversize on purpose
[05:12:47] <cradek> are these the kind with a set screw on a key?
[05:13:06] <jmkasunich> no key, there is a flat on the motor shaft
[05:14:24] <jmkasunich> heh, construction reamers are used to align bolt and rivit holes, etc
[05:14:33] <jmkasunich> tolerance +0.008 -0.000
[05:14:38] <cradek> that explains the bizarre taper too
[05:14:57] <cradek> nice. put that one in the circular file I guess...
[05:15:14] <jmkasunich> no, I'll keep it for when I need to align bolt holes
[05:15:37] <cradek> I suggest you mark it .504 then :-)
[05:15:53] <cradek> fool me once, etc etc
[05:16:04] <jmkasunich> I'll remember
[05:16:29] <cradek> the shop is enclosed again (new wall and doors where the garage door was)
[05:17:01] <jmkasunich> nice
[05:17:34] <jmkasunich> ohh, I just remembered something
[05:17:40] <jmkasunich> I think we have a 0.5005 reamer at work!
[05:17:53] <cradek> sounds very useful
[05:18:38] <jmkasunich> the motor shaft measures 0.4998, so 0.5000 would be a bit tight anyway
[05:19:01] <cradek> I thought you had a set you use for dowel pins - are they 3/8?
[05:19:16] <jmkasunich> I have for 1/4" dowels
[05:19:21] <cradek> ah
[05:19:24] <jmkasunich> 0.2497 and 0.250?
[05:19:29] <jmkasunich> slip and press fits
[05:20:53] <jmkasunich> I think I'll run into work tomorrow and see if that reamer is there, if not I guess its time to buy one
[05:21:05] <jmkasunich> crap, not tomorrow, later today
[05:21:11] <cradek> ha
[05:21:19] <cradek> too bad you can't just bore it
[05:22:01] <jmkasunich> the steel just doesn't want to take a good finish
[05:22:15] <jmkasunich> kind of gummy, if you know what I mean
[05:22:20] <cradek> yeah
[05:22:38] <cradek> do you have 1/2 drill rod?
[05:22:46] <jmkasunich> probably
[05:22:49] <jmkasunich> D-bit?
[05:22:53] <cradek> yeah
[05:23:03] <jmkasunich> too much like work
[05:23:24] <jmkasunich> gotta harden it and everything
[05:23:32] <cradek> that's the fun part
[05:23:36] <jmkasunich> its late tonight anyway, I'm not gonna start another pulley
[05:25:17] <jmkasunich> if we don't have one at work, I might make a d-bit
[05:26:16] <cradek> good thing there's no key - you'd be out of luck
[05:26:37] <jmkasunich> yeah, unless I get a keyway broach
[05:26:56] <cradek> well I was thinking you couldn't ream it
[05:27:04] <jmkasunich> oh
[05:27:22] <jmkasunich> most likely boring from 3/8 out to 0.495 or so prior to reaming would eliminate the keyway
[05:27:35] <jmkasunich> spiral flute reamer might bridge the keyway too
[05:28:38] <cradek> I'm glad I'm a long way away from marc's 2m/s machine
[05:29:28] <jmkasunich> "long way" as in "when it crashes the flying parts won't fly all the way to nebraska"?
[05:29:32] <cradek> right
[05:29:54] <cradek> may as well not bother with an estop button - no way you could hit it in .1 sec
[05:30:32] <jmkasunich> bumpers
[05:30:55] <cradek> yeah you could stop it on about the 6th bounce
[05:35:03] <cradek> goodnight!
[05:35:09] <jmkasunich> ditto
[05:35:15] <jmkasunich> (must have sleep now)
[05:41:03] <toastydeath> fff
[11:42:43] <kwaj> hello
[11:44:21] <kwaj> i have one problem, ifter i upgraded for emc 2.1.7 to 2.2.1 my configuratin setup doesn't work any more. Were there some changes made in configuration files also?
[11:49:59] <alex_joni> yes
[11:50:02] <kwaj> I get this error: " styrocutter.hal:125: setp requires 2 arguments, 3 given "
[11:50:33] <alex_joni> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UPDATING
[11:50:52] <alex_joni> specifically for your issue: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UPDATING#setp_requires_2_arguments_3_given
[11:51:26] <kwaj> will check that, thank you

[17:23:02] <jlmjvm> jepler:
[17:24:07] <jlmjvm> jepler:that was already in the usr/bin/axis,does it just need a widget on the gui to work?
[18:11:40] <kwaj> if i run emc2 from console the "emc2 configuration selector" window doesn't show "my configurations". Why is that?
[18:15:03] <dmess> Why is news in this house always BAD news.... my inlaws were on the explorer that sank off antarctica yesterday.. havent heard from them yet..
[18:16:06] <jlmjvm> didnt the news say they got the passengers off ok
[18:16:45] <dmess> yes.. it did... but it would still be nice to hear for the 67 yr old lady or the 72 yr old man...
[18:17:03] <jlmjvm> of course
[18:17:04] <dmess> they arent spring chickens..
[18:17:20] <dmess> and the old guy HATES water..
[18:17:34] <dmess> cant swim etc...
[18:18:09] <dmess> i doubt they'll be booking any cruises.. anytime soon
[18:18:18] <jlmjvm> i heard that
[18:18:49] <jlmjvm> hope you hear from them soon
[18:19:10] <dmess> i dont believe a fist size hole would sink a ship like that personally....
[18:19:31] <jlmjvm> sounded hard to believe on cnn last nite
[18:19:40] <dmess> it has navigated the N-W passage.. and lived..
[18:19:45] <jmkasunich> yeah, I thought that was strange too
[18:20:01] <jmkasunich> I wonder if the hole dimensions are in feet, not inches
[18:20:15] <dmess> and they have pumps from hell... unless there is more to that
[18:20:31] <dmess> or meters??
[18:21:41] <jlmjvm> yeah,you would figure a boat that size in those waters would have some pumps that would keep it from sinking with a hole that size
[18:21:53] <dmess> I guess the old guy will have a good story to tell me when he gets home...
[18:22:39] <jlmjvm> that would be a really good 1
[18:22:50] <dmess> http://news.bbc.co.uk/2/hi/americas/7108835.stm
[18:24:03] <dmess> apparently the same ship that rescued the passenges did it about 10 months age in the same area...when another ship was lost there
[18:24:14] <dmess> ago
[18:24:55] <jmkasunich> wow, a person from the travel company is repeating the "fist sized hole" part
[18:24:57] <jmkasunich> that is pathetic
[18:25:13] <dmess> yes... but it cant BE
[18:25:44] <dmess> http://www.portsmouth.co.uk/latest-national-news/Rescued-liner-tourists-on-way.3519908.jp
[18:27:05] <jmkasunich> Watertight doors were described as "not as required"
[18:27:13] <jmkasunich> sad
[18:27:53] <jmkasunich> a fist sized hole should only compormise one compartment - it's not like the Titanic where the gash extended through five
[18:28:19] <dmess> yup...
[18:28:32] <dmess> this was SOOOO lucky
[18:28:40] <jmkasunich> either the amount of damage has been hideously understated, or that ship was a disaster waiting to happen
[18:29:21] <dmess> I cant see the ship... someone isnt telling all about the damage... and pump situation...
[18:29:47] <jmkasunich> I would hope a ship that size would have pumps with piping that is bigger than "fist sized"
[18:29:57] <jmkasunich> water comes in thru fist sized hole with a few psi behind it
[18:30:03] <dmess> this was a much smaller - heartier ship than the T
[18:30:14] <jmkasunich> water goes out thru 4x fist sized pipe with a big-ass pump pushing it
[18:30:18] <jmkasunich> pump should win
[18:30:50] <dmess> i agree.. and it would have that.. im wondering if they all worked properly..
[18:31:12] <jlmjvm> i bet there was a failure
[18:31:21] <jmkasunich> and even if the pump loses - a single flooded compartment shouldn't capsize or sink a ship
[18:31:32] <dmess> "Spirit of Shackleton" he froze in the ice and died.. didnt he??
[18:32:23] <dmess> i agree.. there is more to this story/picture.. i wonder if its a drinkin'&drivin' incident again...
[18:32:48] <dmess> like the Exxon-Valdez
[18:34:55] <jmkasunich> it will be interesting to see what comes out as time goes on
[18:35:14] <jmkasunich> although if the ship is on the bottom, it might not come out
[18:36:03] <dmess> precisely....
[18:37:12] <dmess> Dad's pretty astute.. im sure he would have been listening to all conversations he could on-board... so we'll see what story he tells about the bumps...
[18:42:02] <dmess> http://www.firstcoastnews.com/news/news-article.aspx?storyid=96313
[19:07:54] <skunkworks> thanks giving meal - take two. turkey is in the roaster.
[19:27:00] <jlmjvm_> jepler:in tkemc you can click offset and it opens a dialog box to enter tool#,length,and dia,would this same function in work in axis?
[19:27:31] <jlmjvm_> if it had an offset button on the screen
[19:41:51] <jlmjvm_> alex_joni:tkemc has a button called offset that opens a dialog box,would this work in axis if it had a button?
[19:47:39] <alex_joni> jlmjvm_: what do you mean?
[19:48:04] <alex_joni> in order for it to work, you need to add the button, then write a dialog, and code up everything on the dialog
[19:48:13] <alex_joni> AXIS can't just pop up dialogs from tkemc
[19:52:01] <jlmjvm_> http://pastebin.ca/796111
[19:52:29] <jlmjvm_> alex,that is already in /usr/bin/axis
[19:59:03] <jlmjvm> is that a legitimate command to append the tool table
[20:02:40] <jlmjvm> is tkinter.py the tkemc gui file
[20:13:12] <alex_joni> tkinter.y has nothing to do with tkemc
[20:14:09] <alex_joni> tk is basicly the same toolkit used by axis (prom python), and by tkemc from tcl/tk
[20:16:15] <alex_joni> from, not prom
[20:17:27] <jlmjvm> /usr/bin/axis is where you can make changes to axis,where do you go to make changes to tkemc?
[20:20:00] <jlmjvm> want to try and find the command thats making the tool offset function work,also its saving the numbers you enter in the dialog box,but they are not going to the tool.tbl file
[20:20:27] <jlmjvm> dont know where they are being saved,but its working
[20:23:17] <alex_joni> tkemc.tcl is usually in /usr/local/emc2/tcl iirc
[20:27:58] <jlmjvm> mine was in /usr/share/emc/tcl finally found it
[20:32:33] <alex_joni> ok, that.. wasn't very sure about the path
[20:34:46] <jlmjvm> i didnt even know the correct file name till you told me,had no hopes of finding it
[20:36:20] <jlmjvm> this stuff wont work in axis will it,because its tcl instead of py
[20:43:08] <alex_joni> yes
[20:56:08] <jlmjvm> yes,it wont work?
[21:04:50] <alex_joni> yes, it won't work
[21:10:20] <jlmjvm> actually if i could just get the tool.tbl to pop open from a button on the axis gui it would be good enough,then enter the value manually like tkemc or mini
[21:11:02] <jlmjvm> would that be a more realistic approach
[21:12:32] <jlmjvm> instead of trying to auto set the current z position to a specific spot in the .tbl file
[21:19:08] <alex_joni> File->Edit tool table ?
[21:24:07] <jlmjvm> yes,but without having to go to File first
[21:24:59] <jlmjvm> it shows lower case t as the hotkey for edit tool table,but mine doesnt work
[21:28:47] <alex_joni> alt-f-t
[21:29:24] <jlmjvm> that worked
[21:29:51] <jlmjvm> can that be changed in the axis.py file
[21:30:06] <alex_joni> * alex_joni doesn't know
[21:30:22] <jlmjvm> where did you find that command?
[21:30:44] <alex_joni> in the menu
[21:31:02] <alex_joni> alt-f opens the File menu, alt-t opens the "t" highlighted entry
[21:33:02] <SkinnypuppY34> Puppy wonders what jlmjvm is working towards? An easy touchoff TLO in Z? I've yet to complete my z so its a hurdle ahead for me .
[21:33:02] <jlmjvm> mine doesnt have those
[21:33:33] <jlmjvm> yes,that is my goal
[21:34:07] <SkinnypuppY34> AAh making sure I was reading that right
[21:34:09] <skunkworkds> skunkworkds is now known as skunkworks
[21:34:26] <alex_joni> hi samco
[21:43:34] <dmess> Don & Ruth Perry are those im looking for.... GIC someone has seen them menthioned...
[21:52:39] <cradek> AXIS has file/edit tool table
[22:17:29] <SkinnypuppY34> Anyone know what these collars are for on these adjustable reamers? There's also two by themselves in the top of the pic.
[22:17:31] <SkinnypuppY34> http://imagebin.org/11970
[22:18:01] <jlmjvm> cradek:is there any way to open the tool file with alt-t only,instead of alt-f and alt-t
[22:19:10] <jlmjvm> forgot about the caps
[22:20:59] <SkullWorks-PGAB> what about a simple keyboard macro which just outputs the Alt-F/Alt-T assigned to a single key...
[22:21:44] <SkullWorks-PGAB> but you would have to remember it.
[22:27:16] <jlmjvm> file open for example can be reached with alt-f /alt-o,or just o
[22:27:46] <SkinnypuppY34> jlmjvm: are you trying to avoid the mouse also? I just noticed in tkEMC if you left click the GRAY BOX next to offset it will open the same set tool offset window instead of alt+ t
[22:30:25] <jlmjvm> yes,i saw that earlier
[22:37:48] <SkullWorks-PGAB> * SkullWorks-PGAB guesses he might not be the only one who still prefers tkemc
[22:38:26] <SkullWorks-PGAB> for mill
[22:41:05] <jlmjvm> my nasa buddie is working on making a button to open the tool table with,but is having to learn python as he goes
[22:42:41] <SkullWorks-PGAB> for axis?
[22:42:45] <jlmjvm> then we will direct our attention towards making it actually put the number in the correct spot like a regular mill should have
[22:42:48] <jlmjvm> yes
[22:42:57] <jlmjvm> axis
[22:43:51] <jlmjvm> i have never run a mill that didnt have a tool set button
[22:51:39] <SkullWorks-PGAB> true but its also common to have to go thru multible pages/commands before you reach that button.
[22:53:23] <SkullWorks-PGAB> even with a Haas which puts the button on the main panel - you still have to get to the proper offset page for it to be active.
[23:04:45] <jlmjvm> agreed,you should be in offset mode to enter a value
[23:06:10] <jlmjvm> so an arbitrary push of the button doesnt reset any stored values
