[03:43:50] <Loetmichel> mornin'
[05:36:32] <jthornton> morning
[07:50:44] <V0idExp> Hi all!
[07:51:09] <V0idExp> Is there any way to get the current value of some hal pin from python?
[07:53:09] <r00t4rd3d> does ArcEye from the forums ever come here?
[07:54:04] <r00t4rd3d> or is that archivist?
[07:54:13] <mazafaka> maybe under another name
[07:54:20] <mazafaka> could be
[07:57:07] <V0idExp> any suggestions?
[07:57:24] <V0idExp> (02:39:21 PM) V0idExp: Is there any way to get the current value of some hal pin from python?
[07:57:55] <V0idExp> looked at linuxcnc.stat struct
[07:57:58] <V0idExp> *object
[07:58:17] <V0idExp> but nothing which is related to pins is present, as it seems to me
[08:06:21] <V0idExp> guuuys :( help a poor noob :)
[08:07:26] <jdh> someone will probabl answer
[08:07:52] <V0idExp> ok, waitin'
[08:08:29] <jdh> I assumed you googled and the answer won't show up in the first few hit when I look?
[08:11:22] <jdh> http://linuxcnc.org/docs/html/common/python-interface.html
[08:11:31] <jdh> http://linuxcnc.org/docs/html/hal/halmodule.html
[08:11:36] <jdh> perhaps?
[08:12:56] <V0idExp> I have the first link opened in another tab since yesterday... and the second describes how to write hal components
[08:13:43] <V0idExp> I need to write a simple daemon, which polls the state of some pins and sends them over network
[08:14:17] <cpresser> write a comp and load&connect it in hal.
[08:14:22] <cpresser> second link :)
[08:15:16] <jdh> or sh + halcmd + nc
[08:16:57] <V0idExp> well... it's an idea. I have more than a simple daemon, right now... so the solution would be write a comp, link it with my daemon (which already talks with a remote client) with unix sockets via some simple proto or an RPC mechanism...
[08:51:29] <automata_> hi mhaberler
[08:51:52] <mhaberler> hi amit
[08:52:04] <mhaberler> how are things going?
[08:52:46] <automata_> trying to get xenomai going...
[08:53:01] <automata_> on 10.04
[08:53:14] <mhaberler> down in the coding sweatshop, you mean ;-?
[08:53:17] <automata_> downloading xenomai and kernel sources now..
[08:53:35] <automata_> yup... still at the sweatshop..
[08:54:36] <automata_> v0idExp: I have written something like that...
[08:54:55] <mhaberler> did the search for xenomai in the ubuntu package stream turn up something usable?
[08:55:29] <V0idExp> what you have used for IPC?
[08:55:34] <automata_> http://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCAQFjAA&url=http%3A%2F%2Fcode.google.com%2Fp%2Fjhu-lcsr-ros-pkg%2Fwiki%2FUbuntuXenomai&ei=Cip0UMqGGcnlyAG324HYBw&usg=AFQjCNFHGgdFHOI19W_9Q2U3fwhVmUAsMQ
[08:55:50] <automata_> mhaberler: code.google.com/p/jhu-lcsr-ros-pkg/wiki/UbuntuXenomai
[08:55:56] <V0idExp> I mean, for the link heavy_daemon <-> lightweight_hal_listener?
[08:55:58] <mhaberler> <ep
[08:56:04] <V0idExp> looking at dbus...
[08:56:23] <automata_> I have based my program on halrmt and emcrsh...
[08:56:34] <mhaberler> dbus for what, IPC?
[08:57:16] <mhaberler> VOidExp: linuxcnc3 will be based on zeromq for IPC, so better try that
[08:57:29] <automata_> dbus is a good mechanism for IPC... we use it in our digital sinage products...
[08:57:47] <mhaberler> right, and is going exactly nowhere outside linuxland
[08:59:01] <mhaberler> automata: looking at the instructions your guys will be done after some easy 739 steps ;)
[09:00:37] <mhaberler> ah, excellent, that recipe shows how to do debs
[09:13:38] <r00t4rd3d> does this look cheesy ? http://i.imgur.com/bLQa4.jpg
[09:14:13] <jdh> IMO wooden plaques like that are meant to look cheesey.
[09:14:38] <r00t4rd3d> its going to be the top of a paradise box
[09:17:30] <cradek> sorry, but yes
[09:17:35] <cradek> I don't know what a paradise box is
[09:17:53] <cradek> uncurving the text might help
[09:18:27] <cradek> and it's odd that the fish are bigger than the bear, and flying above the trees
[09:18:50] <jdh> you should have seen the one that got away!
[09:18:58] <cradek> um, was I too honest?
[09:20:40] <jdh> no, but really... have you ever seen a carved pine thing that wasn't cheesy?
[09:22:03] <cradek> I suppose there a lot of very cheesy things that people nevertheless buy and give as gifts
[09:22:12] <cradek> so maybe whether it's cheesy is the wrong question to ask
[09:22:16] <jdh> sure, it's not bad, just what it is.
[09:22:19] <cradek> I'm seeing your point.
[09:23:39] <jdh> http://tinyurl.com/8bfh7z9
[09:24:45] <jdh> so, there are a few that aren't.
[09:29:58] <cradek> urghghghehhghrrrrrhhhgggg! http://img1.etsystatic.com/000/0/5230528/il_fullxfull.275426565.jpg
[09:31:22] <jdh> heh
[09:32:01] <skunkworks> yikes
[09:32:09] <skunkworks> atleast it adds up..
[09:32:50] <cradek> Look out - I'm illiterate and I have a gun: http://img2.etsystatic.com/006/0/6651402/il_fullxfull.355046838_2zci.jpg
[09:33:28] <skunkworks> The bite pattern looks more like a shark...
[09:33:29] <skunkworks> http://www.google.com/imgres?start=136&hl=en&safe=off&sa=X&tbo=d&biw=1600&bih=757&tbm=isch&prmd=imvns&tbnid=4tNkDICXiqSN7M:&imgrefurl=http://www.possumhollowfarm.net/id20.html&docid=lpPdF29zhN2hKM&imgurl=http://www.possumhollowfarm.net/sitebuildercontent/sitebuilderpictures/.pond/bewareofthedog.jpg.w560h334.jpg&w=560&h=334&ei=tjJ0UJHPEYb9ygHk34DgCQ&zoom=1&iact=rc&dur=541&sig=101031889934416306799&page=4&tbnh=100&tbnw=167&

[09:33:34] <skunkworks> oh - ouch
[09:35:22] <skunkworks> http://www.possumhollowfarm.net/sitebuildercontent/sitebuilderpictures/.pond/bewareofthedog.jpg.w560h334.jpg
[09:36:03] <cradek> cute idea but the font is hideous
[09:36:31] <cradek> r00t4rd3d: you only need to be less cheesy than the most cheesy ones. so don't worry.
[09:37:46] <jdh> just send them that 2+2 one at the same time. Anything you make will look great next to it.
[09:41:25] <r00t4rd3d> i deleted it all
[10:26:50] <BHSPiMonkey> cradek: the tresspasser's what?? that detail is important to know...
[11:09:52] <tjb1> JT-Shop: you here?
[11:11:37] <tjb1> JT-Shop: Here is the re-made Z - http://sphotos-a.xx.fbcdn.net/hphotos-ash3/548126_4424585888760_830357319_n.jpg
[11:12:28] <r00t4rd3d> cradek, how is the cheese factor on this one http://i.imgur.com/BcrW1.jpg
[11:14:19] <mazafaka> miswrites
[11:15:10] <tjb1> r00t4rd3d: Whats with the dragons and birds?
[11:15:30] <r00t4rd3d> i dont know
[11:15:31] <mazafaka> r00t4rd3d: and cradek Soviet radial-drilling machine conversed into the milling one: http://www.youtube.com/watch?v=rIDsnhCbzv8
[11:15:55] <cpresser> r00t4rd3d: you should not rotate the lower two dogs/dragons
[11:16:10] <mazafaka> tjb1: nothing with them, the word is written incorrectly
[11:16:30] <r00t4rd3d> mazafaka, that is a name
[11:16:36] <mazafaka> Oh...
[11:16:38] <r00t4rd3d> not a lesson
[11:16:41] <r00t4rd3d> :D
[11:16:45] <mazafaka> :)
[11:16:46] <tjb1> r00t4rd3d: The dragons and birds dont really go with the bass :P
[11:16:56] <r00t4rd3d> fuck you all
[11:17:06] <tjb1> lol
[11:17:19] <tjb1> Put some fishing rods or worms there ;)
[11:17:43] <r00t4rd3d> I need to come up with something
[11:18:17] <r00t4rd3d> something with fish or deer or hunting in general
[11:19:19] <tjb1> *cough* aluminum gantry supports *cough*
[11:19:46] <r00t4rd3d> *cough* money *cough*
[11:19:53] <mazafaka> r00t4rd3d: hunting is bad. If it's a commercial offer, you finally will have to come up with your style. Be direct and rough, don't try to overwhelm everything, customer never knows what he really needs.
[11:20:01] <tjb1> Do you drink from aluminum cans?
[11:21:36] <mazafaka> r00t4rd3d: create several different samples with various graphics, ask more of what they really want. I worked in such industry earlier...
[11:22:15] <mazafaka> Thay finally arrange everything in the draft and it becomes they style
[11:22:39] <mazafaka> s/their/they
[11:30:12] <tjb1> r00t4rd3d: Do you drink out of aluminum cans?
[11:46:33] <mazafaka> tjb1: Aluminum is badd as material for food-containing thingies, although there are plenty of such stuff is produced in Soviet Union, for example. Now those plantsa re back in military stuff.
[11:47:02] <tjb1> mazafaka: What arey ou talking about?? Drinks in aluminum cans are everywhere
[11:47:16] <tjb1> https://www.google.com/search?sugexp=chrome,mod%3D8&q=soda+can&um=1&ie=UTF-8&hl=en&tbm=isch&source=og&sa=N&tab=wi&ei=SlJ0UOyxAuji0gGXzIGoAw&biw=1680&bih=868&sei=TFJ0UL-hB4m30AGBl4GwDA
[11:47:53] <mazafaka> tjb1: Aluminum is bad, stainless teel is better
[11:48:27] <mazafaka> tjb1: oh, these are crappy drinks...
[11:48:29] <tjb1> also very expensive….and the cans are coated on the inside
[11:49:14] <mazafaka> this all is bad, it's better to be vegan to understand something, try to be vegan, tjb1
[11:49:48] <tjb1> No, I like bacon
[11:50:54] <tjb1> Whats vegan going to get you? 5 more years of diapers? :P
[11:54:35] <mazafaka> tjb1: after work, i spend a lot of time doing something, i do not sit behind the computer like you. Spend some time thinking what veganism can give you before using phrase like 'what the avoidance of bacon can give you?' The one what you do not even imagine! :)
[11:54:57] <tjb1> Sit behind the computer like me huh?
[11:55:06] <tjb1> Good luck being a vegan.
[11:55:07] <mazafaka> Maybe
[11:55:18] <mazafaka> I have a damn dirty job...
[11:55:30] <mazafaka> I even edit G-codes in DOS mode
[11:55:35] <tjb1> CSB
[11:55:40] <mazafaka> I mean in DOS program
[11:55:52] <mazafaka> What is CSB?
[11:55:54] <tjb1> g-code is text..how hard is that?
[11:56:05] <tjb1> http://www.urbandictionary.com/define.php?term=CSB
[11:56:37] <mazafaka> tjb1: I sometimes simply do not know how to get the correct size, because milling bits reduce in their diameter.
[11:57:08] <tjb1> Thats set in cutter compensation...
[11:57:13] <tjb1> Why arent you using it?
[11:57:26] <mazafaka> I need some drawing program to accomplish it, and instead, I have a DOS program and a crayon
[11:57:54] <tjb1> No you need to learn how to use cutter compensation as its poor to program based on tool diameter
[11:58:54] <mazafaka> tjb1: reasons are: cheap conversed machine, DOS program, grasphics part of it works unstable, we are given with G-code programs produced by 'skilled" personnel... you can imagine and other reasons...
[11:59:09] <tjb1> Not using cutter comp makes the program way to difficult to adjust and because your toolpaths are following an offset line instead of the finished line so its very difficult to read also
[12:00:03] <mazafaka> tjb1: no, I will not add it into the program and thereby be responsible for non-cheap details produced this way.
[12:00:33] <tjb1> Well good luck continuing to program without cutter comp, I see a lot of scrap in your future ;)
[12:01:04] <tjb1> Plus a lot of wasted hours scratching your forehead trying to find the number you need to offset.
[12:01:18] <mazafaka> tjb1: why? there are people who assemmble this precise stuff together, and I only get tolerances on holes or such
[12:01:34] <tjb1> Do you understand what cutter compensation is?
[12:01:43] <mazafaka> I can not offset something, the contour is complicated.
[12:02:09] <BHSPiMonkey> this is getting pretty flamey
[12:02:12] <tjb1> Yes so why make it harder by programming the tool offset into the program
[12:02:20] <mazafaka> tjb1: I know, but part of the program isn't workingm I would like to use the tool length compensation as well
[12:02:41] <tjb1> Are you using Linuxcnc?
[12:04:23] <mazafaka> tjb1: Do you think I run LinuxCNC under DOS? Just stop tell me stupid alphabet of CNC, I'm not unqualified. I has already told to you: we make money running crap. Thats all.
[12:04:52] * BHSPiMonkey smells a troll
[12:04:59] <mazafaka> We run some 1997-200 self-made shit
[12:05:17] <tjb1> So if you are qualified why arent you using cutter comp?
[12:05:31] <tjb1> http://linuxcnc.org/docs/html/gcode/tool_compensation.html
[12:05:36] <mazafaka> BHSPiMonkey: moron, http://www.youtube.com/watch?v=rIDsnhCbzv8&feature=plcp
[12:06:42] <mazafaka> tjb1: I had no time to check out how my exact machine behave with tool diameter compensation. It's some self-made stuff with integral schemes in PCI slots.
[12:07:04] <tjb1> Well good luck continuing to program the tool diameter in...
[12:07:16] <mazafaka> tjb1: if it's interesting for you, I would say thay it isn't working before me, returning stop errors
[12:07:44] <tjb1> Well im out to work on parts and not sit in front of the computer all night, bye mazafaka ;)
[12:08:27] <mazafaka> I finall y have told them to buy small in diameter mills, and arranged the RPMs and feedrate range, and machine works continously, now I plan to change the job, I want something better.
[12:08:38] <mazafaka> it's evening, buy
[12:09:00] <BHSPiMonkey> that's a pretty lousy video. recorded on a vegan camera?
[12:09:38] <mazafaka> I will have to teach another guy soon, do you think idea of milling some wood stuff would help?
[12:11:41] <mazafaka> BHSPiMonkey: some cheapest Samsung for 30$, its screen and camera are covered with tape. Otherwise its screen will be scratched. Steel is damn dirty here... Everything is cheap, although some orders come from German and other countries, and they buy it and use.
[12:16:18] <IchGuckLive> hi all
[12:16:19] <mazafaka> I have learnt here how the plants are working. Several years ago, there was plentiful of work for atomic industry here, now they do virtually all, and even try to use old CNC machines with no ports at all, the ones which memory is powered with flat 4.5V battery from the store...
[12:16:35] <IchGuckLive> live from roswell stratos jump http://www.redbullstratos.com/live/
[12:17:07] <mazafaka> Such machines and other mindfucks aren't for me...
[12:17:44] <IchGuckLive> mazafaka: the world goes on
[12:18:13] <IchGuckLive> as the first humen tuday is trying to break the sound bar without any help
[12:18:18] <mazafaka> IchGuckLive: I meant old, really old CNC machines
[12:18:30] <IchGuckLive> i got 2 of them
[12:18:56] <mazafaka> we made them working, and young dumb fucks are assking why don't I use the tool diameter compensation...
[12:19:04] <IchGuckLive> mazafaka: for a sqare it is a 3m long punch line
[12:19:11] <mutilator> IchGuckLive: heh i was just about to post that too
[12:19:30] <IchGuckLive> 1meter sorry
[12:19:37] <mazafaka> IchGuckLive: for what square?
[12:19:57] <IchGuckLive> a simple sqare to be milled
[12:20:37] <IchGuckLive> i got in a box 25meter rolls for a CHamill
[12:21:28] <mazafaka> oh, the code?
[12:22:23] <mazafaka> No, we have a 'modern' machine - this one use 3,5'' floppy disks, and couldn't work for longer than 40 minutes machinning something.
[12:23:00] <IchGuckLive> 2diskets one code 2nd mashine parameters ?
[12:23:29] <mazafaka> the problems is, when I quit the text editor, graphics window fails to open, the spindle goes down and can break the mill bit.
[12:24:03] <IchGuckLive> on the old one
[12:24:10] <IchGuckLive> or on linuxccn
[12:24:13] <mazafaka> IchGuckLive: DOS, Norton Commander, coordinate-drilling machine converaed into milling one
[12:25:01] <IchGuckLive> how big is the mashine
[12:25:14] <IchGuckLive> is it worth to transform
[12:25:25] <mazafaka> I have written couple of pages for the one willing to work at it, he will rock the machine, not me.
[12:25:42] <mazafaka> IchGuckLive: http://www.youtube.com/watch?v=rIDsnhCbzv8&feature=plcp
[12:25:47] <mutilator> i should be updating computer bioses right now
[12:25:49] <mutilator> but bleh
[12:26:37] <mazafaka> 1300x600-800x400 mm travel
[12:26:43] <IchGuckLive> mazafaka: nice so it is definit worth to work with it
[12:27:24] <IchGuckLive> Roswell ballon enflating starts now
[12:28:00] <mazafaka> IchGuckLive: if it would have LinuxCNC, yes. I had to endure their attempts to use huge mills on it, 4-flute 60 mm in diameter ones, for example.
[12:28:30] <IchGuckLive> mazafaka: check the elektronict if you can get it with the /i77
[12:28:36] <IchGuckLive> 7i77
[12:28:51] <IchGuckLive> it is worth to spend 180 dollars to it
[12:29:00] <mazafaka> hah...
[12:29:09] <IchGuckLive> just houk up the pins to the drivers
[12:29:19] <mazafaka> it has integral electric schemes in PCI slots, that's all
[12:29:29] <mazafaka> there are no drivers
[12:29:49] <mazafaka> part of schemes has fractures
[12:29:58] <IchGuckLive> and the cables
[12:30:01] <mazafaka> but nevertheless work
[12:30:22] <mazafaka> Our WFL need another, more powerful cable...
[12:30:24] <IchGuckLive> servo +envoder
[12:30:43] <IchGuckLive> O.O c
[12:32:11] <mazafaka> we bend one scheme a little to make it work. Another time, I had to ask people around stop to use hammers to continue working.
[12:32:16] <IchGuckLive> is the factory punching 15mm plates as the noice sounds
[12:32:41] <IchGuckLive> havy sheering
[12:33:13] <IchGuckLive> Roswell update all systems on GO
[12:37:03] <mazafaka> http://img-fotki.yandex.ru/get/6422/137304751.2/0_9a8e7_2787424b_orig
[12:37:45] <IchGuckLive> howmany axis are controlled
[12:38:08] <mazafaka> 2.5 D, tool changer isn't working
[12:38:51] <mazafaka> <d40 mm mill bits, 90-to-450 RPMS
[12:41:26] <mazafaka> Sometimes it used to create holes in 7-meter-long something, I can not imagine Russian owners buying modern machines. In our country, we only can sell what we dig out of the mother earth. Damn capitalists have destroyed everything to conquer the rich territories of Moter Russia! >:o
[12:42:59] <mazafaka> This is what have happened on the local Coal Miners Day: http://www.youtube.com/watch?v=UDyYbrEmSh0
[12:44:39] <IchGuckLive> my factory also reduced all the old big ones
[12:45:42] <mazafaka> http://www.youtube.com/watch?v=6MAOLbylg8A
[12:46:07] <mazafaka> Theya re like Russian maybe. ...Or they like Russians.
[12:46:15] <mazafaka> :)
[12:54:52] <mazafaka> Damn Local Military Enlistment Office is trying to make a run of a year-ago stuff that I was not visiting them at proper time. Trying to make me responsible in a manner of applyint the law. That's why I feel uncomfortable, and plan to buy a third bicycle, used BMX... People advise to record the visit on tape...
[12:57:41] <mazafaka> Damn criminals in the governemnt in '93-2000 have accepted too much of stupid laws. It's weird how they didn't give a gun to everybody drinking vodka...
[13:02:29] <IchGuckLive> Roswell caled off
[13:02:37] <IchGuckLive> 17mph wind
[13:04:35] <pcw_home> Is this the Red Bull jump?
[13:04:42] <IchGuckLive> yes
[13:04:50] <IchGuckLive> http://www.youtube.com/user/redbull/featured?v=vkJ5ItzEq3M
[13:04:56] <IchGuckLive> called off
[13:05:33] <pcw_home> I see is says it needs <2 MPH winds
[13:06:00] <IchGuckLive> 2 windboe tock the balon down
[13:08:19] <pcw_home> Not good (in my juvenile delinquent days I used to make big PE ballons from cheap .0005 dropcloths)
[13:10:59] <pcw_home> I think 9x12 ft were about $.29 when I was a kid, about 6 of those an a lot of scotch tape...
[13:12:06] <mazafaka> delinquent derelict how long ago was lamenting in protest (of something)? Years, years...
[13:12:18] <IchGuckLive> 3mio spend on this attempt
[13:13:22] <pcw_home> mazafaka is either waxing poetic or inebriated
[13:13:53] <mazafaka> pcw_home: Sex Pistols
[13:14:00] <mazafaka> music
[13:14:59] <mazafaka> pcw_home: neuther, just copying some stuff to mp3 player
[13:15:07] <mazafaka> neither*
[13:18:14] <mazafaka> And on Monday I called guilty for avoiding local MEO, although hardly I will sit in prison for it. Idiots imaging me like I am fatty and sit at home and watch footbal games with beer and snacks. They're finding something in me, in my optimistic face maybe...
[13:19:13] <mazafaka> Nothing is about having a good life here, every thing and deed is full of shit.
[13:23:39] <mazafaka> It would be nice if someone would make a bacon out of these bad people, and sell it to meat eaters. :) Ha-ha, ta-da, I'll go relaxing in huge bath...
[13:24:19] <pcw_home> Solyent red?
[13:43:49] <skunkworks> green?
[13:48:42] <archivist> I believe soylent green is made from the same ingredients :)
[13:49:45] <pcw_home> red is the bacon flavored variety
[13:51:13] <skunkworks> ah ;)
[14:02:38] <Loetmichel> but green is the kind that is made of humans
[14:03:09] <mazafaka> it's a cooked, non-cheap shit, anyway.
[14:03:17] <Loetmichel> and wasnzt red made of Krill or something?
[14:03:28] <Loetmichel> shrimps?
[14:04:06] <Loetmichel> mazafaka: what is "meo"?
[14:04:29] <mazafaka> Loetmichel: Military Enlistment Office
[14:04:45] <Loetmichel> ah, so you are young?
[14:05:21] <Loetmichel> germany has just last year tcancelled the mandatory service for men
[14:05:39] <mazafaka> Loetmichel: no, i am 28
[14:05:40] <Loetmichel> ... a bout 20 jears to late for me ;-)
[14:05:59] <Loetmichel> 28 nIS <oung ;-)
[14:06:09] <Loetmichel> IS young
[14:06:21] <mazafaka> how? 28 is almost 40
[14:06:39] <Loetmichel> depends on viewpoint. i am 43
[14:06:40] <Loetmichel> ;-)
[14:07:32] <mazafaka> people at whom I' am a guest to install Windows and software hide their daughters, but it's because I'm old, not young. Some called to poilice...
[14:07:59] <Loetmichel> ?
[14:08:08] <mazafaka> viewpoint is to reel like you're 16
[14:08:38] <Loetmichel> you helbp them with their computers and they call the police?
[14:08:52] <mazafaka> people already hide young 'brides' from me...
[14:09:32] <mazafaka> I touched young female users
[14:09:50] <Loetmichel> may be its not because of your ages but '*cause of your looks? :-)))
[14:10:16] <mazafaka> i look young and damn sexy, the mirror says
[14:10:29] <Loetmichel> mirroe lying?
[14:10:33] <Loetmichel> :-)
[14:10:43] <mazafaka> no, it stays along the wall
[14:10:55] <Loetmichel> hrhr
[14:11:43] <mazafaka> lying mirror... what a disorder it would be.
[14:11:54] <mazafaka> weird
[14:11:55] <mazafaka> ;)
[14:12:19] <Loetmichel> then maybe it is BECAUSE of your good looks and knowledge... the eparens fear you steal them the daughters?
[14:12:38] <mazafaka> so, mirror isn't lying, it stays for... me... is young and damn good.
[14:13:01] <Loetmichel> ant has a ego size of a mountain :;-=
[14:13:01] <mazafaka> Maybe.
[14:13:05] <Loetmichel> :-)
[14:14:26] <Loetmichel> its always the sameold story: the eager one s donte get the girl, bu being older, wise lokking and UNINTERESTET gets the girls ;-)
[14:15:28] <mazafaka> uninterested? Any computer guy is interesting!
[14:17:22] <Loetmichel> MarkusBec: YOU uninterested
[14:17:33] <Loetmichel> not uninteresting
[14:18:20] <Loetmichel> means: the girls go to the guys wo doesen t show them any interest... so they have to WORK to get it ;-)
[14:19:34] <Loetmichel> dont ask me how much avances i got since i wear an wedding ring... talk "forbidden fruit" ;-)
[14:19:52] <BHSPiMonkey> Loetmichel: I know that one
[14:20:24] <Loetmichel> annd i am not exactly the best looking kind ;-)
[14:20:49] <BHSPiMonkey> too bad that now that I'm single again and need its help the most, it's no longer appropriate to wear it...
[14:20:58] <BHSPiMonkey> catch 22
[14:21:56] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12346
[14:22:02] <mazafaka> I would install Windows to her computer: https://www.google.ru/search?q=juliet+elliot&hl=ru&newwindow=1&client=firefox-nightly&hs=mQg&rls=org.mozilla:en-US:unofficial&prmd=imvnso&tbm=isch&tbo=u&source=univ&sa=X&ei=5HV0UNWiH7CN4gTdz4D4Cg&ved=0CCYQsAQ&biw=1280&bih=707
[14:22:21] <mazafaka> I'll go and buy BMX tomorrow to turn this bad thoughts on my mind towards good deeds.
[14:22:32] <BHSPiMonkey> mazafaka: you must really hate this chick
[14:23:12] <mazafaka> BHSPiMonkey: why? she looks sexy
[14:23:30] <mazafaka> Loetmichel: you look good according to the photo
[14:23:57] <Loetmichel> MarkusBec: if you say so...
[14:24:04] <Loetmichel> grr
[14:24:07] <Loetmichel> mazafaka
[14:24:47] <Loetmichel> 40 punds less and some training will do , but at the moment i am a bit our of "shape"
[14:24:48] <Loetmichel> :-)
[14:25:15] <BHSPiMonkey> need to trim down fast? there's a GCODE for that
[14:25:20] <mazafaka> Loetmichel: When John Travolta was kid, people used his photos to scare other kids, and now look what he does! He has his own airplane!
[14:25:34] <BHSPiMonkey> just stay very still while the mill takes off 40 pounds
[14:25:39] <andypugh> BHSPiMonkey: No reason that you can't decide that a ring on your left ring finger indicates avaiability. Why should you conform to convention?
[14:25:56] <cradek> this channel has really gone to hell.
[14:26:17] <andypugh> Loetmichel: No, you are very much in shape. The problem is that the shape is "Spherical" :-)
[14:26:17] <mazafaka> any ring means unavailability
[14:26:19] <BHSPiMonkey> cradek: does any channel not?
[14:26:45] <mutilator> related: http://spred.me/f/48136/1349803379157.jpg/
[14:26:48] <mutilator> sfw
[14:26:48] <andypugh> Ah, yes, back on subject please chaps.
[14:26:51] <mazafaka> Loetmichel: 'wrong' pounds = 'human kindness'
[14:29:02] <mazafaka> http://data.whicdn.com/images/29602578/1475674-10-1337804312912_large.jpg
[14:29:10] <Loetmichel> andypugh: right
[14:29:29] <mutilator> so.. for scanning
[14:29:35] <mutilator> probe or laser cam?
[14:30:00] <andypugh> Possibly both.
[14:30:10] <Loetmichel> andypugh: mi wife keeps saying: "my husband hasnt a sixpack. He has a whole KEG!"
[14:30:36] <Loetmichel> ... when describing me to her colleaguesw
[14:30:40] <Loetmichel> -w
[14:32:04] <andypugh> mutilator: What do you want to probe/measure?
[14:33:32] <mutilator> just thinking of copying different surfaces and then adding to them to create wax&soap molds
[14:38:27] <andypugh> Surface probing tends to be very slow.
[14:39:04] <andypugh> But using structured light and cameras is non-trivial
[14:39:19] <mutilator> yea, time isnt really a huge issue
[14:39:25] <mutilator> it could take 2 hrs
[14:39:40] <mutilator> but good to know
[14:39:59] <andypugh> I don't know if it has been done, but you could imagine a config where the Z axis was servoed onto the surface.
[14:40:31] <andypugh> Then you could perform a raster scan and log Z. I suspect that is what the dedicated probing machines do,
[14:40:59] <andypugh> 2 hours might be an under-estimate. What scan resolution would you want?
[14:41:18] <mutilator> heh
[14:41:32] <mutilator> well i suppose if imaging might work faster/better i could try that to
[14:41:34] <mutilator> too
[14:41:46] <mutilator> hmph
[14:42:00] <andypugh> The problem is that imaging isn't exactly a solved problem yet, as far as I know.
[14:42:23] <andypugh> A laser rangefinder might be a solution.
[14:44:14] <Loetmichel> andypugh: david laserscanner?
[14:44:33] <andypugh> http://www.ebay.com/itm/Used-Micro-Epsilon-OptoNCDT-LD-1605-4-Laser-Sensor-with-Sensor-Cable-/190722983076?pt=LH_DefaultDomain_0&hash=item2c67f9c4a4
[14:46:14] <andypugh> That's cheap enough that I would have bought it myself if it was in the same country. And I don't even have any use for it.
[14:49:13] <andypugh> (It only has a 4mm sensing range, but I could imagine using it to maintain a constant "hover height" and logging tha height.)
[15:12:28] <tjb1> Hey andypugh
[15:12:55] <andypugh> Hi
[15:15:24] <tjb1> http://sphotos-a.xx.fbcdn.net/hphotos-ash3/548126_4424585888760_830357319_n.jpg
[15:17:05] <tjb1> and http://sphotos-b.xx.fbcdn.net/hphotos-ash4/304385_4424735052489_943225844_n.jpg
[15:17:09] <tjb1> Goal accomplished :)
[15:17:22] <r00t4rd3d> http://imagebin.org/231421
[15:17:29] <r00t4rd3d> how does that look?
[15:18:42] <jdh> better
[15:19:03] <tjb1> That looks great r00t4rd3d
[15:19:07] <tjb1> No more dragons and birds :P
[15:19:26] <jdh> those fish look saltwater though
[15:20:07] <tjb1> hahaha
[15:20:46] <tjb1> Those pictures were for you andypugh
[15:21:18] <r00t4rd3d> andypugh, i found out alex can and might update the forums
[15:21:58] <andypugh> tjb1: That's clearer
[15:22:16] <tjb1> andypugh: Thats the re-design I did today
[15:22:25] <tjb1> I can now suck it up past the lower carriage
[15:23:12] <andypugh> What is the asembly on top of the extrusion for?
[15:23:56] <r00t4rd3d> he likes just adding weight
[15:25:07] <tjb1> Hold the torch
[15:25:57] <andypugh> On the face of it it looks like 7 components more than necessary. Is it a break-away meachanism or something?
[15:26:20] <tjb1> its floating touch off
[15:26:25] <sliptonic> pcw_home: I'm seeing some strangeness while tuning servos. Are you around?
[15:26:29] <cradek> r00t4rd3d: have you experimented with asymmetrical (non-mirrored, non-centered) layouts?
[15:26:41] <tjb1> and its really 6 pieces :P
[15:26:49] <tjb1> Until I add this - http://sphotos-b.xx.fbcdn.net/hphotos-snc6/189233_4425549312845_1372514786_n.jpg
[15:27:17] <cradek> r00t4rd3d: like on web pages and business cards, everything being centered says amateur to me
[15:29:02] <tjb1> Yeah r00t4rd3d, you need to left align "Le", center align "es" and right align "on" ;)
[15:29:26] <andypugh> tjb1: You have a wire-eroder?
[15:29:35] <tjb1> At the school yes :)
[15:33:29] <tjb1> 4 wire edms, 2 sinkers and a small hole
[15:34:23] <tjb1> 2 of the wires are Mitsubishi and 2 are Sodicks, 1 of the sinkers is a Sodick and not sure of the brand on the rest. The Sodick wires are an A280 and AQ325L
[15:34:39] <andypugh> I think I have a small hole in my workshop, but I dropped it and can't find it again.
[15:35:22] <tjb1> You dropped it?
[15:36:03] <andypugh> It was an attempt at humour.
[15:36:17] <r00t4rd3d> i orderd a tslot bit today
[15:37:06] <andypugh> I think you generally slot-drill the slot first, before Tee-ing it.
[15:37:41] <r00t4rd3d> http://www.mlcswoodworking.com/shopsite_sc/store/html/smarthtml/pages/bt_keyhl.html
[15:37:47] <tjb1> andypugh: Looking at that torch clamp, do you think it can compress to 1", the hole inside is 1.010"
[15:38:00] <tjb1> .052" gap
[15:38:11] <andypugh> .52 / pi = ?
[15:38:40] <tjb1> its that simple?
[15:38:52] <andypugh> I think so.
[15:39:04] <tjb1> Came out to .0165
[15:39:21] <tjb1> Should work...
[15:39:45] <tjb1> If not I will make another and this time I will remember to leave enough stock to tap the one side of the tab this time.
[15:39:54] <WillenCMD> does anyone know how the kernel latency test in the rtai correlate's to the base-thread in linuxcnc
[15:39:58] <andypugh> looked at another way, you need to compress .030 to be 1", then the rest is preload.
[15:40:53] <tjb1> I didnt have the torch up here so I hope its a little oversized
[15:42:37] <exco> after a day fiddling with pid parameters on vsd-xe devices and within the linuxcnc ini's my head hurts ;-)
[15:44:26] <andypugh> Nested loops are always the most fun.
[15:45:03] <andypugh> WillenCMD: This might come as a surprise, but the correlation between latency test and base thread time has never been entirely clear to me.
[15:45:49] <andypugh> Something here I was previously naware of "hold down straps" for milling: (fig 8.24) http://www.americanmachinetools.com/how_to_use_a_milling_machine.htm
[15:51:09] <tjb1> andypugh: I made this new one so both carriages are bolted to the plate with 3/8-16 and a bolt is used in all 4 holes on all carriages and I can still mount the motors. Before I had the Y carriages held on with 2 5/16-18 per carriage
[15:51:31] <tjb1> Plus I can cut off 6" of the acme screw
[16:08:25] <tjb1> I need to bring my physical e-stop into linuxcnc so it shuts that down too, time to blow another input
[16:08:57] <exco> someone experienced with vsd-xe alnd linuxcnc?
[16:09:07] <exco> *and
[16:09:39] <andypugh> tjb1: Possibly the most useful use of an input, though.
[16:10:37] <JT-Shop> tjb1: nice Z
[16:10:47] <tjb1> andypugh: You dont happen to know if I can modify something to gain I/O use of the VFD outputs on the G540
[16:11:18] <andypugh> Driving from LinuxCNC and parport?
[16:11:27] <tjb1> Yes
[16:11:42] <skunkworks__> you could technically re-map coordinate rotation to g68 couldn't you.. Wait - isnt that what gmour(sp) did?
[16:11:43] <JT-Shop> remove the 4th axis from the 540?
[16:11:45] <andypugh> Just pull the wires out of the connector?
[16:12:09] <andypugh> skunkworks: That's exactly it, yes
[16:12:18] <tjb1> I need the 4th axis JT-Shop
[16:12:22] <JT-Shop> or get one of those parallel breakout connectors
[16:12:28] <skunkworks__> neat
[16:12:32] <JT-Shop> on a plasma?
[16:12:37] <tjb1> My gantry has two drives
[16:12:47] <JT-Shop> ok your gantry has two motors
[16:13:17] <skunkworks__> for when they come back and say bla bla bla g10 r isn't industry standard gcode..
[16:14:32] * JT-Shop needs to complete the shamblazation process in the shop so the de-shamblizing can commence
[16:15:39] <tjb1> JT-Shop: What does the "start-motion-input thc.arc-ok" mean/do in this "# starts the motion when the plasma arc has transfered to the work
[16:15:39] <tjb1> net start-motion-input thc.arc-ok <= motion.digital-in-00 <= parport.0.pin-15-in"
[16:15:49] * JT-Shop thinks there is no industry standard except RS274, the rest do what they want anyway
[16:16:34] <JT-Shop> in touchoff.ngc I wait for the ark ok
[16:17:27] <tjb1> But that is using the M66 with P0 right, so is that just naming that so you know what it does?
[16:17:38] <tjb1> I see on the M66 page that P0 calls the digital input 0
[16:17:46] <JT-Shop> the signal name?
[16:18:13] <JT-Shop> thc.arc-ok is a pin
[16:20:47] <tjb1> Oh thats used in your xml file for your display?
[16:21:51] <JT-Shop> what is that?
[16:22:02] <tjb1> the "thc.arc-ok"
[16:22:09] <tjb1> That is "made" to use in your xml file?
[16:22:16] <JT-Shop> no, that is a pin in the thc component
[16:22:37] <Connor> can LinuxCNC handle Resolvers ?
[16:22:43] <JT-Shop> a pyvcp pin will be pyvcp.pin-name
[16:22:49] <tjb1> net motion.digital-in-00 <= parport.0.pin-15-in <----will that work if I dont need the pin right now?
[16:23:11] <JT-Shop> no, it will never work without a signal name
[16:23:36] <JT-Shop> your talking about two things and confusing me
[16:23:59] <tjb1> Im confused too, dont worry
[16:24:07] <skunkworks> Connor, mesa hardware has resolver interfaces...
[16:24:10] <JT-Shop> read this again http://linuxcnc.org/docs/html/hal/basic_hal.html#_net_a_id_sub_net_a
[16:24:39] <Connor> skunkworks okay. That's what I was thinking.
[16:24:53] <skunkworks> Connor, pico systems has a resolver to quaduature converter board
[16:25:06] <JT-Shop> net start-motion-input thc.arc-ok <= motion.digital-in-00 <= parport.0.pin-15-in has a signal name and 3 pins
[16:25:19] <JT-Shop> start-motion-input is the signal name
[16:25:34] <Connor> skunkworks better to use the converter board, or just a mesa hardware ?
[16:25:40] <JT-Shop> you can drop the thc.arc-ok if your not using the thc component
[16:25:45] <DJ9DJ> gn8
[16:25:49] <tjb1> so I can make it "net arc-ok motion.digital-in-00 <= parport.0.pin-15-in
[16:25:49] <skunkworks> Connor, what are you trying to do?
[16:25:52] <JT-Shop> night
[16:26:07] <JT-Shop> yes that will work
[16:26:31] <Connor> Local guy has a Arrow 500 VMC.. He's having major issues with the Emerson control systems, he's thinking about gutting it and switching to a PC based setup.
[16:27:26] <tjb1> <= means the parport.0.pin-15-in is inputting its signal/data into motion.digital-in-00?
[16:31:17] <tjb1_> Sorry JT-Shop computer locked up
[16:33:29] <sliptonic> PCW: I'm making another go at tuning servos and still trying to understand what I'm seeing. Have a minute?
[16:34:26] <tjb1_> So JT-Shop the <= would mean the right side inputs to left side
[16:34:54] <JT-Shop> tjb1_: <= means nothing
[16:35:17] <JT-Shop> http://linuxcnc.org/docs/html/hal/basic_hal.html#_net_a_id_sub_net_a
[16:35:20] <tjb1_> Just a direction indicator to the user
[16:35:27] <JT-Shop> yes
[16:36:03] <tjb1_> Alright thanks, I should be able to get torch firing this weekend now
[16:36:14] <JT-Shop> the paraport in pin is a signal source
[16:36:34] <JT-Shop> the motion.digital in is a signal reader
[16:36:53] <JT-Shop> PULL THE TRIGGER!
[16:37:01] <JT-Shop> sorry for the caps lock
[16:38:16] <tjb1_> Maybe thursday night
[16:39:06] <tjb1_> For the spindle on you have to give it an S value right
[16:39:26] <JT-Shop> yep >0
[16:39:51] <tjb1_> What do you use for CAM
[16:40:10] <JT-Shop> gedit mostly
[16:40:22] <tjb1_> So you hand code
[16:40:48] <JT-Shop> unless it is an artsy fartsy part then I use sheetcam
[16:41:04] <tjb1_> How do you like sheetcam?
[16:41:07] <JT-Shop> or onecnc
[16:41:35] <JT-Shop> it's cheap and makes a profile cut just fine
[16:41:49] <JT-Shop> I don't think he updates the linux version much
[16:42:02] <JT-Shop> the gui is klunky but workable
[16:42:03] <tjb1_> Oh yeah, is the Linux version free?
[16:42:36] <tjb1_> The website last time I looked didnt say anything about restrictions or expiration on the Linux version
[16:42:55] <JT-Shop> I've not looked in a while
[16:43:13] <tjb1_> http://www.sheetcam.com/downloads.shtml
[16:43:38] <tjb1_> He has in red bold letters on the TNG Stable and dev version that it is limited to 180 lines of code but that warning isnt on the Linux version
[16:45:34] <tjb1_> Did you have to pay for your linux version?
[16:46:01] <JT-Shop> I got it a long time ago when it was beta I think
[16:47:00] <tjb1_> You dont happen to use draftsight for the geometry ?
[16:47:43] <JT-Shop> no
[16:49:21] <tjb1_> Alright thanks JT-Shop, im out of questions for tonight
[16:50:09] <JT-Shop> but you had one more left in the que :)
[16:50:18] <tjb1_> ?
[16:50:34] <JT-Shop> you had one more question you could ask lol
[16:50:54] <tjb1_> but im not paying for a CAD program so it doesnt matter :P
[16:51:20] <tjb1_> Im sure there is free cad on linux, pretty sure I seen it in the linux store
[16:52:22] <JT-Shop> qcad and another one that I forget
[16:53:21] <JT-Shop> $16 bucks for shipping on two tiny metering valves
[17:07:23] <andypugh> tjb1_: freeCAD?
[17:07:57] <andypugh> http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page
[17:08:10] <JT-Shop> what was the one that split off from qcad?
[17:09:07] <Tom_itx> tjb1_, did you figure out your home button?
[17:09:08] <andypugh> I am not sure
[17:09:24] <Tom_itx> JT-Shop how's your machine conversion going?
[17:10:10] <JT-Shop> pretty much done except for making a cover for the touch screen and cutting a DB25 hole in the electrical panel
[17:10:20] <andypugh> Marvellous. freeCAD Mac works OK, except that "About freeCAD" crashes it :-)
[17:11:02] <tjb1_> Tom_itx: no
[17:12:00] <JT-Shop> home button?
[17:12:07] <Tom_itx> uh huh
[17:12:12] <Tom_itx> the one i stole from you
[17:12:43] <JT-Shop> LibreCAD
[17:13:06] <andypugh> I think LibreCAD might have been QCAD?
[17:13:23] <andypugh> freeCAD is 3D Parametric, a bit like HeeksCAD
[17:13:30] <JT-Shop> yea, but improved and is working on g code generation I think
[17:13:34] <Tom_itx> http://www.dynapath.com/page_k3.htm
[17:13:40] <Tom_itx> wonder what that runs
[17:16:23] <tjb1_> Hey andypugh, do you know if Sheetcam for Linux is free?
[17:16:57] <andypugh> No, it's commercial.
[17:17:14] <tjb1_> Whoever runs the website needs to clear that up
[17:17:14] <andypugh> I am using the demo version because I am bad.
[17:17:38] <JT-Shop> if you pay Lester he will clear that up
[17:17:54] <andypugh> It's Les Newell, we see him on the mailing list sometimes.
[17:18:02] <tjb1_> Gonna be a while before I can shell out $180
[17:18:18] <andypugh> See ow far you get with the demo then.
[17:18:30] <andypugh> I intend paying at some point.
[17:18:39] <JT-Shop> what kind of parts are you going to be cutting?
[17:18:43] <tjb1_> Ill use mastercam at the school ;)
[17:19:20] <Tom_itx> mmm i haven't tried any plasma templates
[17:19:32] <tjb1_> Does sheetcam have a post you can edit?
[17:19:43] <JT-Shop> yes
[17:19:53] <JT-Shop> and you will want to edit it
[17:20:00] <tjb1_> For the touchoff :)
[17:21:33] <Tom_itx> i wonder if i even have any
[17:23:24] <JT-Shop> tjb1: http://filebin.ca/IYUILyjxYfG/EMC-Plasma.scpost
[17:24:08] <JT-Shop> now that Tom_itx mentioned it I think I'll pick up the tools laying around the BP
[17:25:03] <tjb1> Thanks JT-Shop
[17:25:44] <JT-Shop> np
[17:27:56] <Tom_itx> machining center with horizontal and vertical heads?
[17:28:12] <Tom_itx> Phillips control
[17:32:05] <Tom_itx> mmm look like all mill in this directory
[17:32:20] <Tom_itx> couple have A axis wrap geometry
[17:45:01] <tjb1> nothing worse than busy work in college
[17:47:07] <Tom_itx> i should have unzipped these years ago

[17:49:02] <tjb1> What are you unzipping?
[17:49:30] <Tom_itx> a bunch of files i collected when i bought my cad cam
[17:54:17] <Tom_itx> addon to create variable radius blends between surfaces
[18:19:51] <Nick001-Shop> Any pages on hooking driving steppers - Slo-syn 5vdc - 1A - actual power supply etc
[18:20:23] <Nick001-Shop> hooking up and driving
[18:20:52] <andypugh> Do you have stepper drivers?
[18:21:19] <Nick001-Shop> no not yet
[18:22:11] <r00t4rd3d> jdh, the lady didnt like my fish
[18:22:13] <Nick001-Shop> cross slides with steppers, brakes and linear scales and would like to get them operating
[18:22:22] <r00t4rd3d> "they dont look like a walleye or bass"
[18:24:48] <andypugh> Nick001-Shop I see no reason that they would be any different from any other steppers.
[18:30:50] <Nick001-Shop> I dont have info on any steppers - been doing servos.I've seen steppers rated at 3v hooked up to 24 supplies and not burn out. Can I hook these up to a 24v supply and not burn them out
[18:33:50] <Nick001-Shop> I have a mesa 5120and 7130 - looking to use the stepper driver with the 5120. Can I still have the 7130 hooked up to the 5120 at the same time to drive servo components also on the same special purpose machine?
[18:39:28] <andypugh> 5V steppers will be fine at 24V. It might even be a little low.
[18:39:46] <andypugh> (It is the current that matters, and the drivers look after that)
[18:40:34] <andypugh> In theory you can have servo and steppers on the same 5i20. In practice you might not find a suitable bitfile.
[18:41:01] <andypugh> It is possible to make custom bitfiles. (I have done it)
[18:44:59] <Nick001-Shop> A 1amp rating will pull what under load or is that the max it will draw?
[18:45:46] <andypugh> It doesn't draw, it is given\
[18:46:10] <Nick001-Shop> Would I have to use a second 5i20 to avoid the bit file problem?
[18:46:15] <andypugh> The stepper driver allows 1A to flow through the motor. That's its job.
[18:46:42] <andypugh> That's the easiest way, but not the cheapest.
[18:46:49] <andypugh> How much is a 5i20?
[18:47:17] <PCW> There are standard bitfiles that have servo and step/dir interfaces (though the pinout may not be ideal)
[18:47:30] <andypugh> You could, in theory, run a base thread and software stepgens.
[18:47:51] <andypugh> Ah. PCW is the one to talk to, I will leave you to him.
[18:48:19] <Nick001-Shop> thanks andy
[18:49:34] <tjb1> r00t4rd3d: Did you show her the dragons and fish?
[18:49:38] <tjb1> Birds I mean
[18:49:40] <PCW> the common SVST4_4 config has 4 servo channels and 4 stepgens but somewhat odd pinout
[18:50:02] <Nick001-Shop> PCW - looking to drive some steppers with the 5i20 and 7i30 cards I have and know zilth about steppers
[18:50:44] <Nick001-Shop> is the pinout defined somewhere?
[18:50:51] <PCW> do you have step/dir drives?
[18:51:43] <Nick001-Shop> 7i30
[18:52:14] <PCW> svst4_4.pin should be in the /lib/firmware/hm2/5i20 dir
[18:52:29] <PCW> the 7I30 will not drive step motors
[18:53:17] <Nick001-Shop> I know can I add 7i32 in the next plugin on the 5i20?
[18:53:49] <Nick001-Shop> and drive both kinds of motors?
[18:54:00] <PCW> Yeah but theres no LinuxCNC support for 7I32
[18:54:30] <Nick001-Shop> what card then?
[18:55:08] <PCW> I separate step/dir drive like Gecko/Leadshine etc
[18:55:17] <PCW> s/I/A/
[18:55:35] <PCW> what current step drive?
[18:55:45] <Nick001-Shop> 1amp
[18:55:55] <Nick001-Shop> 2 motors
[18:56:15] <PCW> I suppose the 7I32 could be supported without too much trouble
[18:56:37] <Nick001-Shop> any docs on this?
[18:56:39] <JT-Shop> http://neme-s.org/Wireless_and_Steam_2012/new_england_museum_of_wireless.htm
[18:57:45] <PCW> it would require special firmware to generate the 7I32s waveforms
[18:58:48] <PCW> (but could pretend to be a normal stepgen so the driver would be none the wiser)
[19:01:07] <Nick001-Shop> trying to stick with standard stuff - just trying to get something that works
[19:02:24] <PCW> Easiest be a separate step/dir input drive
[19:02:29] <Nick001-Shop> will the stepgen work with both boards plugged into the 5i20?
[19:02:37] <PCW> sure
[19:04:20] <PCW> Theres only one obscure I/O combo that has a conflict (UART does not get along with sserial or resolver)
[19:05:28] <PCW> lots of people use mixes of servo/stepgen
[19:05:34] <Nick001-Shop> losing me a little with the terminology - the steppers would be called X & Y and servos would be for 3 drilling spindles with 1 spindle for rigid tapping
[19:06:32] <Nick001-Shop> Mixed usage with all mesa cards - or Geckos thrown in?
[19:06:43] <PCW> just saying there no real limit on what kind of I/O is mixed in one FPGA configuration (or setup with HAL)
[19:07:31] <PCW> Gecko is just a stepgen on the FPGA side, nothing special
[19:08:52] <Nick001-Shop> Ok - I'll order the 7i32 tomorrow so I can actually hook these motors up - Is the 24 v supply enough to drive these motors?
[19:10:48] <PCW> Umm the 7I32 is not currently supported, mixed configurations with servo and stepgen are. I can look at firmware for 7I32 support but cannot guarantee a lead time
[19:13:10] <Nick001-Shop> do you have another card that will work?
[19:15:28] <Nick001-Shop> Dinner time - will be back 1 hr - --
[19:18:13] <r00t4rd3d> thanks for the warning!
[19:31:58] <andypugh> Nick001: For the absolute easiest setup (at a cost) a 5i25 card and a G540
[19:32:17] <andypugh> Ah, he left
[19:32:42] <Tom_itx> the 540 has spindle control too doesn't it?
[19:32:48] <andypugh> Yes
[19:33:01] <PCW> The 7I32 is funny as it really designed for stepmotors with feedback and SoftDMC
[19:33:02] <Tom_itx> that's what i'm lacking
[19:33:30] <Tom_itx> is it feasable to do rigid tapping with steppers?
[19:33:42] <PCW> so its has both angle and current setting from host
[19:33:56] <PCW> I dont see why not
[19:34:03] <Tom_itx> i'm not sure a sherline spindle can be reversed though
[19:34:12] <andypugh> If Nick001 has another use for the 5i20, perhaps he would be better with a 5i25 / 7i77 / G540 combo?
[19:34:28] <andypugh> Though the G540 is overkill for 1A steppers.
[19:34:49] <Tom_itx> what's a good durable driver for 1A ish steppers?
[19:34:52] <Tom_itx> ie NEMA17
[19:35:03] <PCW> Yeah although it looks like one machine and only 1A step motors
[19:35:04] <Tom_itx> maybe 2A
[19:35:35] <PCW> does Leadshine make a small drive?
[19:35:41] <andypugh> Tom_itx: Leadshines are fine
[19:35:51] <andypugh> You can throtthe down...
[19:36:31] <PCW> I'll look at the possibility of supporting the 7I32 with the stepgen
[19:36:49] <Tom_itx> what card is it?
[19:36:56] <Tom_itx> haven't looked at that one
[19:37:50] <PCW> Its really designed for close loop stepmotors and SoftDMC but I think I could hack the stepgen to work with it
[19:38:32] <andypugh> Tom_itx: These would be cool if they worked step/dir http://www.zappautomation.co.uk/uim24302b-self-pulsing-miniature-stepper-driver-p-557.html?cPath=9_3_4
[19:39:16] <Tom_itx> for a closed end stepper yeah
[19:39:19] <andypugh> Actually, for Nick001 those _are_ ideal as they work on analogue voltage, so make his steppers into servos. (sort of)
[19:39:52] <andypugh> He has glass scales for feedback, I think he said.
[19:40:13] <Tom_itx> what form factor is it? 17 or 23?
[19:40:23] <andypugh> 17, but there are 23 adapters
[19:41:12] <Tom_itx> what's self pulsing mean?
[19:41:20] <andypugh> Definitely worth pointing him at those when he gets back, perfect for what he has, I reckon.
[19:41:38] <andypugh> Tom_itx: It means that they create their own step-dir signals.
[19:41:56] <Tom_itx> what controls the step speed then?
[19:42:57] <andypugh> The things listed in the web page?
[19:43:18] <Tom_itx> DAC output?
[19:44:15] <andypugh> http://www.zappautomation.co.uk/uim24002-miniature-stepper-driver-p-8.html is more conventional, 23 sized, step-dir. Not as good for Nick001
[19:45:21] <andypugh> This is what I was really looking for, standard Leadshine-style stepper drive. Perfectly OK and running my machine fine.
[19:45:27] <andypugh> http://www.zappautomation.co.uk/pm542-microstepping-driver-p-5.html?cPath=9_3_4
[19:45:43] <andypugh> And yes, you can rigid-tap with steppers.
[19:45:59] <andypugh> OK, I need to sleep.
[19:46:06] <Tom_itx> later
[20:22:41] <Nick001> is there a US supplier for the UIM24302B? Also ,will it handle steppers with 4 wires?
[20:23:59] <Nick001> Lots of questions - stepper with encoders - will LCNC correst the position or will it stop the movement?
[20:24:10] <Nick001> correct
[20:24:48] <Tom_itx> http://www.alibaba.com/showroom/uim24302.html
[20:24:50] <Tom_itx> china
[20:29:16] <Nick001> I'll look further into that one - china getting expensive with the shipping charges.
[20:42:01] <PCW> you can use stepmotors with encoders as a velocity mode servo
[20:42:03] <PCW> It can still stall if you exceed its capabilities but it is possible to get
[20:42:05] <PCW> better accuracy than a bare stepmotor this way
[20:45:18] <PCW> This does require a high ustep ratio (so the control loop can adjust torque vs load by adjusting usteps from the stepmotors null position)
[20:48:58] <PCW> This is all done in HAL be setting the stepgen to velocity mode and using a PID loop
[20:48:59] <PCW> you can also just fault on a stall if you like, it all depends on how you have you HAL file arranged
[21:18:17] <Nick001> making ny head spin with all the posibilities
[21:18:55] <Nick001> is any of this in the wiki?
