[00:00:40] <Jymmm> this place is a rental, i really dont want to put money into it
[00:01:26] <andypugh> In that case, don't bother being neat. Just screw the braces to the sides of the other bits.
[00:01:50] <Jymmm> nah, just 2x4 brace will be fine
[00:03:41] <Jymmm> thaks for the formula
[02:22:58] <Dave911> GonMD: Check your scaling - I think it is 88,000 steps per inch. That is awfully high.
[02:23:47] <GonMD> Dave911: this might help you understand my problem.

[02:24:14] <GonMD> where the position is, is the physical limit of my x travel, but its only, say, 1/8th the way across the red box
[02:34:36] <roh> hm.. can hal parameters pass strings somehow?
[02:35:27] <roh> i mean.. is there a type for string besides bit, float, s32,u32 ?
[02:52:27] <cradek> nope
[02:53:16] <roh> too bad.. i hoped to name values which i store to a file
[02:53:34] <tom3p> i dont see any string type for hal. and i think you might use an index, liek a pin that had the index of an array of messages that some python/c was able to display
[02:54:11] <roh> index?
[02:54:39] <roh> i hoped to use a simple hal python script which uses pickle to store values
[02:55:15] <The_Ball_> The_Ball_ is now known as The_Ball
[02:55:47] <tom3p> ah, python arrays are different, not neccesarily numeric index, more like key & vale
[02:56:09] <roh> used a dict for now
[02:57:06] <roh> it should get n inputs and increment the value once a second if the input (bit) is true
[02:57:18] <roh> and save the value to a file and read it back on start
[02:58:49] <tom3p> when is the file closed?
[02:59:04] <roh> in exit i hope
[02:59:10] <roh> eh on
[02:59:30] <roh> planned to write and sync periodically
[03:00:48] <roh> i want to accumulate the runtime for some values inside of hal to have some kind of 'runtime total'
[03:01:09] <GonMD> an odometer for a cnc machine. awesome.
[03:01:23] <roh> values like machine_on, program_running, spindle_on and if emc is started
[03:01:33] <roh> real machines have something like that in hardware
[03:01:57] <GonMD> our cincom auto lathes had total uptime and job runtime. but thats it
[03:02:10] <roh> also i want to have all values twice, once with reset button, one which is the total
[03:02:45] <roh> well.. if i get it done one could extend it to log stuff like total toolpath lengh or so
[03:03:54] <roh> i would also like to differenciate G0 from G1/2/3/4 moves, but i dont know where to find some value like that
[03:04:39] <roh> even cooler would be to know spindle load and differenciate unloaded and loaded
[03:07:58] <KimK> And while we're on the subject of time, it would be interesting if Axis could show the estimated time to completion, so you could load a program and know as soon as it's loaded how long it would take to run.
[03:08:16] <Jymmm> it does
[03:08:30] <KimK> Really? where does that appear?
[03:08:39] <KimK> I'm looking
[03:08:42] <Jymmm> in one of the menus
[03:08:43] <tom3p> roh: can u\you use numbered variabels? there's thousands of 'em , like G01 X#1000, they exist in a file thats loaded & saved every emc2 run. but: you'd need to communicated between emc & you counter/timer/logger and keep a list of what # had what name.
[03:09:54] <tom3p> http://www.linuxcnc.org/handbook/gcode/variables.html
[03:13:32] <tom3p> look for an 'emc.var' file
[03:14:45] <roh> tom3p hm... i hoped to do that in the hal file
[03:15:59] <roh> also.. wouldn that be overwritten if somebody used em in some gcode?
[03:19:20] <KimK> Jymmm: I'm still not finding that "estimated time to run" readout, and I can't find it in the user manual. Could you give me another hint? (Unless it's a new feature of 2.4.0, I'm still running 2.3.4)
[03:36:47] <GonMD> Dave911: heh, i had something wrong, the revs/inch of the leadscrew. the scale is now down to 16000

[03:55:08] <cradek> KimK: file/properties
[03:55:53] <KimK> Hi cradek, thanks. How are things?
[03:58:46] <cradek> things are good
[03:59:04] <cradek> back to work tomorrow - took half the day to dig out of the snow today
[04:00:50] <KimK> I'll bet. Surprisingly in Minneapolis it's not bad. Southern Minnesota got hit harder, I hear.
[04:02:42] <cradek> Jeff and I were in CO over the weekend and drove back Monday. We were definitely glad to be home.
[04:08:38] <KimK> Yes, there's the runtime, I never looked in there (properties) before. Thanks!
[04:09:25] <Jymmm> cradek & jepler: Ok, of all the "Duo's" on TV which pait wudl you two say you most resemble? Ren and Stimpy? Beavis and Butthead? Laural and Hardy? Harold & Kumar? Cheech & Chong? Sponge Bob & Square Pants?

[04:12:58] <Jymmm> ...and his powerless finger burner
[04:26:38] <Dave911> GonMD: Sounds like you are getting close to nailing all of the bugs.. :-)
[04:28:47] <GonMD> Dave911: i almost have the workspace red box setup to match my actual table travel. but now i have another problem. the EMC2 AXIS that is always there on bootup. its like, 7" across, but barely fits in the workspace when my workspace is 2'x3' but in stepconf, table travel is 0 to 6.0 X and 0 to 7.5 Y
[04:33:00] <Dave911> GonMD: Why is your table travel in software only 0-6X and 0-7.5 Y ?
[04:34:40] <GonMD> because thats what i have to set it at, for the table travel of the machine to be accurate with the yellow line in the EMC app. otherwise if i set it to 0 to 24.0 and 0 to 36.0 Y the bounds in the app are HUGE and if i try a air test run of the machine it zooms across the table and i have to stop it before it crashes
[04:35:02] <Dave911> Shouldn't the travel be 0-24 x 0-36 ?
[04:36:38] <GonMD> i swear, if i get this working, im going to make a video screen cap of this whole process to help out other noobies like me.
[04:36:57] <Dave911> Are you in G20 or G21 mode - english or metric? Look at the line of codes that are active
[04:37:18] <Jymmm> cradek: Nah, you two are able to work/do things together, seems like everyone has become "domesticated" lately, and no time for anything outside the home.
[04:37:50] <GonMD> lemme run out to the garage and check
[04:39:05] <Dave911> GonMD: What you really need to do is go back through stepconf and put in values that are real physical values. The EMC2 software is really quite robust. You don't need to trick anything into working normally.
[04:40:47] <Dave911> >>air test run of the machine it zooms across the table
[04:40:48] <Dave911> There is no way that should be possible. Your max velocities that I saw were very low. No zooming allowed with those numbers ... ;-)
[04:47:50] <Dave911> I gotta get some sleep.... bbl
[04:58:59] <tom3p> jthornton: are you using on of the plasma-thc configs?

[06:42:58] <toastydeath> I had someone seriously argue with me that f(x) := 6 is not a valid answer to the question "what f(x) satisfies f(8) = 6"
[06:43:07] <toastydeath> and that x-2 was the only valid answer.
[07:39:39] <SWPadnos> toastydeath, you could also have pointed out that ((x^2)-4)/10 satisfies the problem
[07:45:46] <micges_work> SWPadnos: you're up so late?
[07:45:55] <SWPadnos> yes, sadly
[07:46:04] <SWPadnos> and I have a plane to catch in 4 hours
[07:46:10] <micges_work> ouch
[07:46:14] <SWPadnos> yeah
[07:46:23] <SWPadnos> I'm debating whether I should bother trying to sleep at all

[08:14:55] <numen> moin
[10:11:34] <MrSunshine> bad surface finnins when milling is due to? Vibrations ? Milling speeds?
[10:12:24] <MrSunshine> to dull mills? :)
[10:22:29] <piasdom> g'mornin all
[10:31:29] <numen> anyone an idea, why homing the xaxis does not work anymore?
[10:48:17] <MattyMatt> Have you checked the sitches?
[10:48:23] <MattyMatt> switches?
[10:50:43] <MattyMatt> MrSunshine, all of the above :)
[10:51:02] <MrSunshine> MattyMatt, argh dammit :P
[10:51:23] <MrSunshine> saw an movie on youtube where they were milling with endmill and got almost mirror finnish after
[10:51:31] <MrSunshine> might have to do alot with lube etc also =)
[10:51:38] <MattyMatt> also, metal crystalograpy. did you cast white iron?
[10:52:08] <MattyMatt> I've heard that's a bugger to machine
[10:53:07] <MattyMatt> I think you need everything perfect to get a mirror finish. perfect machine, perfect material, perfect mill, perfect spindle and feed rates
[10:53:34] <MrSunshine> MattyMatt, true =)
[10:53:53] <numen> MattyMatt the switches are ok
[10:55:06] <MattyMatt> all the way to the parport?
[10:56:44] <MattyMatt> after that I know nothing. I haven't got my emc machine set up yet
[10:57:33] <numen> yes
[10:57:43] <numen> yesterday it worked...
[10:58:17] <micges_work> numen: use haleter to see if parport pin with switch are changing when you press switch
[10:58:34] <numen> nope it doesnt
[10:59:02] <micges_work> so check your wiring again
[11:02:46] <numen> found the problem
[11:02:50] <numen> the levelshifter died
[11:07:28] <micges_work> good
[11:07:33] <micges_work> bbl lunch
[11:14:21] <MrSunshine> sucks to not have a tool switcher
[11:14:39] <MrSunshine> atm im cadding everything for 1 tool ... and that kinda takes time .. 4mm endmill to drill 5mm holes :P
[11:18:04] <MrSunshine> and building a tool changer requires some engineering .. and smarts :P
[11:18:04] <MrSunshine> oh well, walk the dog .. work some ... bbl
[12:28:17] <MattyMatt> MrSunshine, what are you using for alu stock for casting?
[12:29:52] <MattyMatt> Lionel Oliver doesn't seem to care about mixing alloys with plain alu, but I think it's crucial for alu
[12:30:56] <MattyMatt> some casting alloys are very high in silicon
[13:11:43] <Jymmm> lol
http://www.sodastreamusa.com/
[13:19:48] <MattyMatt> seems like a normal ad. comparing a 12oz glass with a Litre at the end was disingenuous tho
[13:20:35] <MattyMatt> if they are pushing the green angle, they should capture the CO2 from the heating system >:)
[13:20:42] <Jymmm> I guess they've been around in EU for 100 hundred years
[13:21:09] <MattyMatt> I thought it was a US company that's been here for 100 years :)
[13:21:59] <MattyMatt> kids love those machines, for a while
[13:22:00] <Jymmm> Just find it ironic that the syrup in the plastic bottles holds a couple of liters worth, and you have to recycle the CO2 canisters
[13:22:47] <Jymmm> by deposit, and there's a license agreement to have/use the co2 canisters and you can't have them refilled at your local gas store
[13:23:42] <MattyMatt> so they use a proper cylinder? they traditionally use throwaway cartridges
[13:24:03] <Jymmm> $1 refund to you upon return
[13:25:02] <Jymmm> And what ppl don't realize is that it takes 3x more energy to recycle plastic bottles than is does to produce new ones.
[13:25:35] <MattyMatt> energy is less limited than hydrocarbons. it's worth it
[13:25:50] <Jymmm> Though, it only takes 5 water bottles to produce one fleece jacket.
[13:25:57] <MattyMatt> well, until bioplastics replace oil
[13:26:10] <Jymmm> Recycling produces a higher carbon footprnt
[13:26:43] <Jymmm> All our plastic bottles are shipped to China,and they ship back fleece.
[13:26:48] <MattyMatt> that phrase assumes energy = fresh oil
[13:27:15] <MattyMatt> or coal
[13:27:19] <Jymmm> what do yu think trucks and ships use?
[13:29:20] <Jymmm> Heh, coal powered Trucks
[13:29:30] <Jymmm> Yeah,pass a smog chekc now!
[13:29:32] <MattyMatt> they existed
[13:30:19] <Jymmm> So did brothels on every corner
[13:30:27] <MattyMatt> they still do :)
[13:31:03] <MattyMatt> Chinese still have steam trains I think
[13:31:45] <Jymmm> They also have the worse pollution in the world.
[13:31:48] <Dave911> GonMD: Looking good! :-)
[13:31:59] <Jymmm> 2nd only to Chenobal
[13:33:19] <MattyMatt> looks like they've stopped using steam trains over the last 20 years. just a few for tourists now
[13:34:09] <MattyMatt> so, progress
[13:34:17] <Jymmm> I like the idea of steam train
[13:34:56] <Jymmm> There are a few active at the rain museum/private RR line here that you can ride
[13:35:09] <Jymmm> T6
[13:35:11] <Jymmm> t^
[13:35:27] <MattyMatt> I like the look of our station when they decided to scrub all the soot off the glass roof. they only had to do it once
[13:36:30] <MattyMatt> all the public buildings were black, and they only needed one sandblast, but that was the Clean Air Act not the trains
[13:37:13] <MattyMatt> this house was still coal fires when we moved in in 73
[13:51:03] <Jymmm> I think this is just cool...
http://www.vk2zay.net/article/157
[15:26:12] <GonMD> Dave911: thanks. though im still having trouble with table travel and bounds. so i just set theX 0 to 24.0 and Y 0 to 36.0 and homed, did max travel jogging for each axis, then made sure the program i ran fit in that new box.
[15:50:44] <MrSunshine> MattyMatt, whatever i find ... makes very good milling alu atleast ... no lube needed even and very very short cutoffs =)

[17:57:13] <acemi> tom3p: yes
[17:57:27] <tom3p> oh! hello
[17:57:34] <acemi> hello
[17:57:37] <tom3p> nice machine
[17:57:58] <acemi> thanks
[17:58:39] <tom3p> the feed mechanisms on that and the button machine are nice too, is that all Hal code? or Classic Ladder?
[17:59:03] <acemi> hal
[17:59:28] <acemi> I used G code with custom M function
[18:02:53] <jepler> ooh, that's a neat machine
[18:02:58] <jepler> I'm sure I need one of my own
[18:07:25] <KimK> Is it possible to have three different ini files (and tbl & var files, etc.) where the fourth axis can be A, B, or C? I have tried this saying for GEOMETRY= XYZA, XYZB, and XYZC, but the B & C versions don't seem to work right. Any suggestions?
[18:08:16] <KimK> I'm using 2.3.4 and the Axis display, if that helps.
[18:14:43] <jepler> Those geometries do what I expect: they make the cone's point stay fixed while the direction of the cone rotates around A, B, or C respectively when moving the A, B or C axes.
[18:15:01] <acemi> KimK: in the [TRAJ] part, AXES value will be 6 for XYZC IIRC
[18:15:02] <jepler> (I tried by editing [DISPLAY]GEOMETRY sim/axis_9axis.ini and running with each setting)
[18:19:44] <KimK> In "A" mine does that, rotating around X as expected, and the display and jog radiobutton say "A". But in "B" the display and jog RB say A, and don't move on screen. I'm still checking the "C" version.
[18:20:26] <KimK> Now this is in an ini file (and hal files) that I made from looking at the example sim. Shall I post them?
[18:23:23] <acemi> paste.debian.net
[18:23:33] <acemi> to post file
[18:29:57] <alex_joni> http://www.theregister.co.uk/2009/12/10/electropulse_drill/
[18:30:06] <archivist_attic> Im lazy and keep one setting even though I move the rotary around
[18:30:07] <alex_joni> wonder how the sharks will like those
[18:32:59] <KimK> OK, files posted at
http://paste.debian.net/53676/ and
http://paste.debian.net/53677/ and
http://paste.debian.net/53679/
[18:37:08] <KimK> alex_joni: Yes, we might end up keeping one setting too, but I though it might be nice to display the actual(?) geometry. Although our part moves, not the tool. But that would be OK.
[18:41:17] <KimK> The C version seems to behave the same as the B version, display says A, position digits move, tool cone doesn't. And yes, I moved X and Y off of their home positions, one inch each.
[18:43:18] <skunkworks_> don't you have to then have a b and c axis config for it to work as expected? or am I not understanding what you are doing?
[18:45:50] <tom3p> alex_joni: fraunhoffer strikes again, neat stuff
[18:49:14] <KimK> Well, wait a minute, are you saying that I must have in the ini axis 0-8 sections some kind of filler in axis 3-of-9 in order to put my real 4th axis in the axis 4-of-9 slot to have a B display? And then live with a dummy A that isn't there? Maybe that's right, if inconvenient.
[18:51:47] <KimK> Maybe 3-of-9 and 4-of-nine weren't very clear there, I meant 3 as in 0123 and 4 as in 01234. I hope that helps.
[19:01:55] <jepler> If you speicfy XYZA the cone tip will stay fixed; if you specify AXYZ then the tip will move when X and/or Y are not at machine 0.
[19:02:01] <jepler> the same goes for B and C
[19:02:39] <micges> alex_joni: cool technology
[19:02:42] <jepler> and yes, with trivial kinematics you have to use the [AXIS_3] section for A, the [AXIS_4] section for B, and so on.
[19:03:10] <numen> hi

[19:05:45] <numen> * numen hates cam...
[19:06:57] <micges> jepler: are you using 9.04 or 9.10 ? if so did you notice much slower Axis and/or python program?

[19:09:23] <numen_> numen_ is now known as numen
[19:09:34] <numen> i had to write a cam prozessor for inventorcam and emc
[19:10:05] <KimK> jepler: Thanks very much for your help, and I will try the AXYZ version, I didn't know you could do that. I'll try working on the [AXIS_n] business (and related stuff) and see how the B & C display works out.
[19:11:25] <KimK> jepler: wait, you said "with trivial kinematics...", would it work better if I had a "trivkins-a", "trivkins-b", and "trivkins-c"?
[19:16:31] <jepler> personally I'd probably just write my ini/hal files to cope with the skipped axis numbers
[19:20:08] <KimK> OK, if you would do that then I guess that's what I'd better do. Thanks very much again for your advice.

[22:17:07] <jepler> skunkworks_: how big is that table? Looks plenty big for any PCB I can imagine fabricating!
[22:17:46] <jepler> (and dang if it doesn't look like you're using half-and-half for coolant!)
[22:18:08] <numen> does anyone know, how to design non circular gears?
[22:18:30] <archivist_emc> define non circular
[22:18:56] <tom3p> my bike has elliptical chain wheels
[22:19:40] <numen> archivist after 10 seconds
[22:19:42] <numen> http://www.youtube.com/watch?v=y2vRkXoTWqc
[22:19:45] <numen> the planets
[22:20:49] <numen> something like this
[22:20:55] <numen> i need ^^
[22:21:05] <skunkworks_> jepler: the plate is about 27X18
[22:21:16] <skunkworks_> plenty of work space ;)
[22:21:56] <skunkworks_> water based coolant..
[22:22:16] <numen> archivist do you know, how to design?
[22:22:51] <skunkworks_> I have rails and beaing form a dispencing machine I will be using for this project..
[22:22:51] <archivist_emc> I have seen something somewhere Im trying to think where it was
[22:23:17] <skunkworks_> bearings
[22:23:48] <numen> this looks quite interesting ^^
[22:24:12] <archivist_emc> numen, the planets in the last example will be involute form as will the inner gear and outer, but it will be "fun"! making
[22:24:48] <skunkworks_> actually - most of this hardware is getting mounted to that plate
http://www.youtube.com/watch?v=zKZYj51Exn0
[22:25:21] <numen> archivist_emc but i think, not very easy for creating?
[22:25:27] <tom3p> numen look for harmonic drives,
http://en.wikipedia.org/wiki/Harmonic_drive and this ( i didnt download it or know about it
http://software.informer.com/getfree-harmonic-gear-calculation/ )
[22:26:09] <archivist_emc> numen, if you have the right machine you can generate the form of the gears
[22:26:10] <numen> i think, this supports just normal gears? whith standard parts?
[22:26:17] <tom3p> a single involute is hard enuf, but to map them around an oddball cam is very hard
[22:26:33] <archivist_emc> tom3p, simple if generated
[22:26:50] <numen> archivist_emc with which software i can generate something like this?
[22:26:52] <tom3p> yes, if the cutter is an involute :)
[22:27:18] <archivist_emc> or any shape that can generate the set
[22:27:22] <numen> tom3p i think, you can cut them one for one and assemble after?
[22:29:09] <tom3p> dont know, its been years since i did gears on wedm, and then i just entered data into a mini-cad system designed to generate gear profiles
[22:29:28] <tom3p> google is your friend
[22:29:40] <numen> i allready tried...
[22:29:49] <numen> but software for this costs a lot ^^
[22:32:07] <archivist_emc> there is some shareware
[22:32:35] <numen> archivist_emc name?
[22:32:49] <archivist_emc> I did an internal gear for a parachute company that I generated in solidworks
[22:33:08] <numen> archivist_emc solidworks can non circular?
[22:33:18] <numen> like the planetary gear in the viedo?
[22:34:28] <archivist_emc> the planets are standard gears
[22:34:30] <archivist_emc> http://www.bealltool.com/clockforum/index.php?topic=141.0
[22:34:58] <numen> archivist_emc this in the viedo is not round ^^
[22:35:29] <archivist_emc> some are round
[22:36:17] <numen> i want to build an non round ^^
[22:37:19] <numen> i need something for the wall in my room ^^
[22:39:13] <archivist_emc> wedm or laser or generate...the choice is yours, you have a lot to learn
[22:39:27] <numen> mill^^
[22:39:38] <archivist_emc> not mill
[22:39:44] <numen> why not?
[22:40:09] <archivist_emc> mill cannot generate internal
[22:40:31] <tom3p> google clark gear cad for an example in solidworks
[22:40:50] <numen> why should it not be possible to mill the inside?
[22:40:55] <archivist_emc> unless you emulate a gear shaver and make your own cutter
[22:41:43] <tom3p> then look at links for elliptical gears in solidworks... and more
[22:42:37] <numen> tom3p i dont use solidworks...
[22:43:53] <numen> archivist_emc i think, milling should be possible, if i use a 1mm endmill...
[22:44:48] <archivist_emc> numen, book
http://www.amazon.com/Gears-Small-Mechanisms-Wilfred-Davis/dp/1857610156
[22:45:23] <numen> archivist_emc how gears work, i know ^^
[22:45:25] <archivist_emc> see also cambam as he has gear form milling
[22:46:10] <archivist_emc> that book shows you how gears are generated
[22:47:00] <numen> archivist_emc i dont want to buy a book, i want a non circular gear ^^
[22:47:35] <archivist_emc> dont be lazy. I am not going to spoonfeed gear design in irc
[22:47:49] <numen> ^^
[22:48:17] <numen> i just want to know, that there is a free software, for generating something like this
[22:49:17] <bill20r3> fwiw, I've looked, and not found any.
[22:49:44] <archivist_emc> I spotted some stuff while googling something else
[22:50:48] <archivist_emc> and as I said cambam has it built in
[22:51:34] <archivist_emc> but odd shapes will require effort from the user
[22:54:15] <numen> i will try cambam
[23:05:56] <numen> what could be the right word for google that?
[23:10:46] <bill20r3> perhaps "eliptical gears"
[23:35:16] <numen> hmmm
