[00:39:20] <andypugh> jdh: It’s LinuxCNC, with their own UI
[00:41:12] <PCW> might be a linuxcnc-- machinekit mashup
[00:45:06] <__rob> can anyone suggest if this might work. or if there is a better way. My mill has a standard lead screw, whether the table and leadscrew move, rather than the leadscrew being held at one end moving the table. There is a brass block on the bed that the leadscrew goes through.

[00:46:03] <__rob> I was going to have a hex nut, with a square block that has a hex nut socket cut in it, that sits flush agains the table bed, then have a strong spring in between
[00:46:43] <__rob> not sure if that is likely to be enough

[01:20:21] <furrywolf> for some reason firefox insists on saving that url, not opening it.
[01:20:54] <PetefromTn_> then what gives they are saying that is what they have given back to the community....
[01:21:43] <PCW> Pretty sure they paid for his work on the new TP

The basic UI is an important piece of information and it is I think something that should be freely shared. If you are going to sell a machine tool with a system based on an open source program it should all be freely given if you ask me but who am I right...

[03:25:12] <XXCoder1> yeah
[03:25:14] <furrywolf> which I told everyone, and no one listened.
[03:25:23] <furrywolf> and now no one will ever see a product.

[03:26:45] <CaptHindsight> what's the difference, intent?
[03:26:46] <furrywolf> gah! horrible fucking web design! let's have fixed bars on both the top and the bottom of the screen, so you can view the content in a little window in a middle! and you can't scroll properly!
[03:27:50] <CaptHindsight> Ouya's historic $8.5 million campaign
[03:28:32] <CaptHindsight> https://www.ouya.tv/
[03:28:34] <furrywolf> ... and they tell you virtually nothing about the projects, instead expecting you to watch a video for each one?
[03:29:23] <CaptHindsight> http://en.wikipedia.org/wiki/Ouya
[03:30:31] <CaptHindsight> n January 2015, Ouya received an investment of 10 million USD from Alibaba with the possibility of incorporating some of Ouya technologies into Alibaba’s set-top box
[03:30:36] <furrywolf> ... and it has some kind of broken infinite-scrolling crap, and lazy loading, and popup spam. remind me to never, even visit "insidermonkey" again.
[03:30:40] <CaptHindsight> the Alibababox
[03:34:19] <XXCoder1> ard island!

[03:34:46] <XXCoder1> no bars, no popups
[03:35:43] <XXCoder1> luci would rock too bad scam
[03:38:26] <furrywolf> why is it currently popular to design webpages that suck? are there people that go "Ohhh! I like having a bar that takes up screen space all the time, because I'm too stupid to scroll back to the top of the page! durrrr!"?
[03:38:44] <CaptHindsight> it's design in general
[03:38:50] <XXCoder1> furry other fad is what I call "white virus"
[03:39:02] <XXCoder1> it makes website designers use light gray text on white
[03:39:05] <CaptHindsight> look at what they do with each new version or Android, or what happened to gnome
[03:39:14] <CaptHindsight> it's been going on got decades
[03:39:19] <furrywolf> I don't use android. or gnome.
[03:39:39] <CaptHindsight> different to be different not to present information in a better way
[03:39:41] <furrywolf> if I wanted my computer to suck like it ran windows, I'd install windows. :)

[03:41:04] <furrywolf> I've only seen it once, one of my banks. I bitched to them about it. I think they changed it eventually.
[03:41:25] <CaptHindsight> remember when websites all had dark backgrounds ~1999?
[03:41:34] <furrywolf> I mentioned how all their senior and disabled users wouldn't be able to read it, and it was a lawsuit waiting to happen. :P
[03:42:03] <furrywolf> CaptHindsight: no, I didn't consider geocities to be all of the websites. :)
[03:42:05] <XXCoder1> CaptHindsight: that was after google revealed that montiors use less power when dark
[03:42:18] <XXCoder1> thats stll true but not all that much unless amoled
[03:42:41] <furrywolf> when possible, I don't even specify colors. content should be separate from presentation. it's up to the browser to decide what appropriate fonts, font sizes, and font colors are.
[03:44:31] <furrywolf> most browsers used to default to black on grey, most now default to black on white.
[03:46:25] <furrywolf> I can be moderately competent with css... I just prefer to use my skills for good, not evil.
[03:50:03] <furrywolf> I need to learn more css3 though. I only started playing with it the other day. was it you I was annoying with it? I can't remember now. :P

[03:51:33] <XXCoder1> zee I think

[03:53:37] <XXCoder1> I still dont understand /o/
[03:53:37] <furrywolf> it's not. in fact I suspect there's a pretty small overlap between the item and machinists.
[03:53:43] <XXCoder1> concentality something
[03:54:12] <furrywolf> https://us.funfactory.com/en/dildos/amor/ sadly, most machnists don't seem to buy things like that... and yet they use the diameter symbol. :P

[04:09:39] <Tom_itx> just like ^^ that

[04:12:25] <Tom_itx> i just wondered...
[04:12:27] <zeeshan> use my anger
[04:12:30] <zeeshan> to literally copy their gui
[04:12:35] <zeeshan> graphic for graphic
[04:12:42] <zeeshan> just to show how easy it is to do it
[04:12:46] <zeeshan> and publically release it
[04:12:56] <zeeshan> :D
[04:13:00] <zeeshan> turn that anger into positive energy
[04:13:36] <zeeshan> these frigging mach people used to talk shit about linuxcnc for so long
[04:13:38] <PetefromTn_> It is my feeling that if they intend to base their entire system on a free open source program and then SELL it with their machines the LEAST they can do is provide what they have it is not like they are not going to sell machines without it....
[04:13:46] <zeeshan> and now they're using it, and they can't acknowledge the fact they're using it
[04:14:00] <furrywolf> zeeshan: did you know that when two people sue each other, it's not who's right that wins, but who has the most money?
[04:14:18] <zeeshan> furrywolf: the gui will have
[04:14:24] <PetefromTn_> I have no animosity towards Tormach..
[04:14:25] <zeeshan> "author: ANONYMOUS"
[04:14:26] <zeeshan> :-)
[04:14:33] <zeeshan> tormach makes good stuff
[04:14:37] <PetefromTn_> and I HOPE that you can do as you are saying and share it here..
[04:14:38] <zeeshan> i like their tts
[04:14:39] <zeeshan> their machines
[04:14:56] <zeeshan> PetefromTn_: most of that gui andypugh has made using macros
[04:15:00] <tjtr33> tormach didnt say anything yet. they did not say they wouldnt give back.
[04:15:01] <tjtr33> they were pretty nice to linuxcnc inviting us all to thier fest thsi year. and its not released yet. you heard about a preview. loosen up and listen.
[04:15:14] <PetefromTn_> but I do think regardless of the rule of law they have an obligation to share as so many others have freely and willingly
[04:15:26] <Tom_itx> Tormach sorta encorporates Mach right in their name...
[04:15:27] <zeeshan> tjtr33: why is there no mention in their pathpilot pdf ?
[04:15:28] <zeeshan> white paper
[04:15:50] <zeeshan> PetefromTn_: honestly even if they didnt share the gui
[04:15:51] <zeeshan> its okay
[04:16:02] <zeeshan> i just want it to say "powered by linuxcnc"
[04:16:04] <zeeshan> :-)
[04:16:11] <PetefromTn_> not to me it is not...
[04:16:14] <furrywolf> if you're lucky the gui will include some gpl code, then you can force them to release the whole thing.
[04:16:19] <tjtr33> it aint released yet. maybe it will say that.
[04:16:38] <zeeshan> tjtr33: a bunch of people have their slant bed lathes
[04:16:41] <zeeshan> seems pretty released
[04:16:50] <zeeshan> look @ youtube
[04:17:00] <PetefromTn_> I sincerely hope they will do the right thing and make it what it is and has always been. an open source program contributed to by many...
[04:17:02] <tjtr33> the slant bed or the giu? 2 diff things.
[04:17:06] <zeeshan> both.
[04:17:14] <zeeshan> their slant bed comes with linuxcnc
[04:17:15] <zeeshan> standard
[04:17:26] <zeeshan> i haven't seen one slant bed lathe of theis run mach
[04:17:31] <tjtr33> so does the mill, the grinder may also. its cnc
[04:17:32] <zeeshan> *theirs
[04:18:29] <zeeshan> the reason to me its important that they mention linuxcnc
[04:18:30] <tjtr33> bottom line you dont know the whole story listing to a video and inventing the other half. wait for them to say something. maybe good maybe not.
[04:18:34] <zeeshan> is it causes the community to grow
[04:18:44] <zeeshan> more developers, more people making fancy stuff :P
[04:18:58] <zeeshan> tjtr33: the white paper
[04:19:02] <zeeshan> and their website
[04:19:10] <zeeshan> and the people who bought the lathes are proof enough
[04:19:19] <furrywolf> how about you make a linuxcnc interface that's even better than theirs?
[04:19:36] <PetefromTn_> tjtr33 I agree that we should wait and see what they do... it will undoubtedly show thier intentions one way or another..
[04:19:49] <zeeshan> furrywolf: that still doesnt change the fact that they didnt acknowledge the core engine
[04:20:03] <PetefromTn_> Its more than just the core engine..
[04:20:16] <CaptHindsight> BOYCOTT TORMACH!!

[04:20:36] <zeeshan> wouldn't it be cool if this channel doubled in size :-)
[04:20:43] <PetefromTn_> if you read that white paper basically everything they are touting as their own improvements is linuxCNC
[04:20:48] <Tom_itx> zeeshan not really

[04:21:44] <zeeshan> yes
[04:21:53] <Tom_itx> did you get your part cut?
[04:21:54] <furrywolf> is there any way linuxcnc can cope with a home switch at the center of travel without depending on hitting a limit switch first? I guess I'll need some kind of persistant switch that remembers if it's to the left or right of home, so it knows which way to seek the home switch?
[04:21:57] <zeeshan> no
[04:22:02] <Tom_itx> wtf are you here then?
[04:22:04] <Tom_itx> ???
[04:22:07] <zeeshan> i dont wanna run the machine anymore till i get lubrication up and running
[04:22:13] <Tom_itx> heh ok
[04:22:19] <Tom_itx> off the hook for now...
[04:22:22] <zeeshan> lol
[04:22:29] <zeeshan> dude that slant idea
[04:22:30] <zeeshan> was sweet
[04:22:37] <zeeshan> it really opens the door to bigger parts
[04:22:38] <tjtr33> yes you can do that. its open source.
[04:22:55] <zeeshan> do what
[04:22:57] <Tom_itx> probably gains about 2-3"
[04:23:07] <tjtr33> home swx in ctr of table with no limit swx
[04:23:12] <zeeshan> pythogrean theorem

[04:23:16] <CaptHindsight> it's still better than anything reprap or printrun/pronterface
http://reprap.org/mediawiki/images/f/f2/Printrun_fr.png
[04:23:26] <furrywolf> I've been trying to figure out how to home my machine, and with the lathe chuck and tailstock, I can't find any dependably safe way to use limit switches to home... since when you crash your part into the chuck or tailstock can't be sensed with a limit switch.
[04:24:03] -!- MacGalempsy_ [MacGalempsy_!~quassel@ip72-204-45-74.fv.ks.cox.net] has joined #linuxcnc
[04:24:16] <Tom_itx> is this pathpilot anything to do with machinekit?
[04:24:32] <PetefromTn_> my CNC lathe has a home switch near the center of travel and the limit has an arm on the tailstock so it will work regardless of where the tailstock is positioned.
[04:24:35] <CaptHindsight> everyone is still wondering
[04:24:42] <CaptHindsight> Tom_itx: ^^
[04:24:43] <Tom_itx> add me to the list
[04:24:46] <Tom_itx> :)
[04:25:11] <zeeshan> pathpilot sounds like theyre using mesa
[04:25:12] <Tom_itx> and the ones that know aren't saying it appears
[04:25:22] <Tom_itx> that's not bad
[04:25:23] <PetefromTn_> it is mesa
[04:25:29] <zeeshan> i already read on some stuff online
[04:25:33] <zeeshan> its mesa
[04:25:39] <furrywolf> PetefromTn_: I have a lathe/mill combo machine. in mill mode, you have to make sure your part doesn't crash into the lathe parts.
[04:25:42] <PetefromTn_> you can see their card in the photos
[04:25:50] <Tom_itx> PetefromTn_ where?
[04:25:54] <PetefromTn_> I am fully aware of your machine.
[04:25:56] <zeeshan> im glad for mesa!
[04:26:01] <PetefromTn_> Agreed.
[04:26:02] <zeeshan> long live mesa
[04:26:13] <CaptHindsight> maybe they are sworn to secrecy
[04:26:13] <PetefromTn_> in their installation instructions
[04:26:13] <furrywolf> I'll put limit switches at the end of travel, but whether you can reach that end or not depends on where you have your part clamped to the table...
[04:26:16] <tjtr33> you can add an estop switch on the slide that bumps the tailstock or chuck. a prox or a cheapo laser sensor if you cant actually touch
[04:26:21] <CaptHindsight> took a blood oath
[04:26:26] <zeeshan> well thats a business deal
[04:26:30] <zeeshan> thats none of our business to be honest
[04:26:33] <furrywolf> tjtr33: the table doesn't hit the lathe parts, but whatever you clamp to it might.
[04:26:50] <CaptHindsight> even beyond a spit handshake
[04:27:03] <tjtr33> oh the chinese 3-in-1
[04:27:07] <Tom_itx> blood instead of spit?
[04:27:13] <PetefromTn_> you are probably going to want to get used to removing the lathe chuck for milling operations.
[04:27:25] -!- MacGalempsy has quit [Ping timeout: 255 seconds]
[04:27:29] <furrywolf> this is just something I have to be aware of when using the machine... but it also precludes any form of homing that involves travelling all the way to one side or the other.
[04:27:43] <furrywolf> so I want a center home switch, but then it won't know which direction to home...
[04:29:10] <PetefromTn_> I don't think a center home switch is a problem but you may be forced to jog the axis to a position where it will be moving in the correct direction before you hit the home button.
[04:29:52] <tjtr33> home as in bees home, or pigeons home, they know which way to go towards... could be done
[04:30:11] <furrywolf> I'm thinking a clicky toggle switch and a little flipper of some form, that keeps track of which side of home it's on
[04:30:47] <XXCoder1> sorry if but native but why not get seperate lathe and mill?
[04:30:54] <zeeshan> and
[04:30:58] <PetefromTn_> It's only really an issue on the Z axis...

[04:36:28] <tjtr33> if its impossible to do automatically, then do it manually
[04:36:39] <furrywolf> tjtr33: it's a lathe/mill combo, where the lathe chuck and tailstock stick out over the table.
[04:37:03] <tjtr33> yeah i said was just taking mine apart
[04:37:09] <tjtr33> i know the machine
[04:37:22] <furrywolf> I should be able to use a mechanical clicky switch to remember which side it's on... just have a fork-shaped toggle on it and a pin that trips it.
[04:37:49] <furrywolf> I could probably even use this as my home switch, if linuxcnc will accept ignoring it any time except homing.
[04:37:54] <PetefromTn_> if you did that you would need to make some sort of macro for the homing sequence to switch it..
[04:38:06] <PetefromTn_> I think you are over thinking it.
[04:38:32] <furrywolf> in fact, I like that idea. I can do it with only a single switch, don't need a separate microswitch, just the clicky switch.
[04:38:39] <PetefromTn_> upon startup if the axis is on the wrong side just jogging it to the right side will not take more than a moment or two....
[04:40:02] <furrywolf> I ordered a test indicator... should be here next week, then I can square the machine up. I squared it by eye now, it's probably not perfect. (saddle has a rotation joint in it, to let you turn tapers, which I will be bolting tight since I won't use it with cnc)
[04:41:06] <furrywolf> tjtr33: were you the one with the spindle encoder webpage? my memory sucks.

[07:33:54] <anarchos2_> which in theory would have to be released under the GPL, eh?
[07:34:08] <anarchos2_> or they could just be using 2.7...

[07:46:28] <zeeshan> :-)
[07:46:30] <zeeshan> congrads!
[07:46:56] <Swapper> in regards to tormachs desition to go the linux cnc whay that is
[07:47:16] <Swapper> Guess they had some problems getting turning to work in mach :)
[07:47:28] <Swapper> so they had to go linuxcnc or develop a whole new controller
[07:47:54] <Swapper> anyone know what mesa hardware is in the controller ?
[07:47:56] <zeeshan> develop is a strong word :P
[07:48:02] <MacGalempsy> ok the touchscreen workith!
[07:51:01] <Swapper> what would you guys recommend to use for a hardware feed override? i got a quadrature hand weel but maybe thats overkill ?

[08:04:40] <MacGalempsy_> morning DJ
[08:04:43] <Cromaglious> I was cutting some Aluminum today and the Z limit/home switch was false triggering...
[08:05:31] <Cromaglious> think I need to go to a switch with a heavier spring
[08:09:05] <SpeedEvil> vibration?
[08:09:12] <Cromaglious> yep
[08:09:17] <SpeedEvil> Or flying chips :)
[08:10:03] <Cromaglious> Vibration.. Z deflects in the Y direction under heavier cuts
[08:13:03] <archivist> vibration is an error too
[08:13:39] <Cromaglious> which makes the switch go up and down, the direction the contacts move..
[08:14:17] <Cromaglious> slower feed rate then... and rewrite the file to get rid of most of the rapids
[08:14:35] <archivist> make the machine more rigid
[08:14:49] <Swapper> easier to lower the max speed in config ?
[08:14:53] <Cromaglious> it's a 3040 and it's not mine
[08:15:31] <Cromaglious> I am going to lean the gantry back to reclaim some of the table
[08:15:56] <Cromaglious> and raise it so it clears the A axis
[08:17:06] <Cromaglious> probably give it 120mm of clearance from 70ish
[08:17:43] <Cromaglious> really need to get a better spindle. It has a 230w
[08:19:23] <Cromaglious> I have optical limits coming
[08:20:52] <Swapper> i think inductive limits are the easiest to work with, needs some magnetic metal ofcorse
[08:21:10] <Swapper> and physical switches for e-stop
[08:21:18] <Swapper> mecanical
[08:21:23] <Swapper> is the right word :)

[15:59:11] <_methods> how big are the gaskets?

[15:59:42] <_methods> how many?
[15:59:47] <jdh> 2
[15:59:50] <_methods> oh lawd
[16:00:05] <_methods> xacto knife lol
[16:00:10] <Rab> ^^
[16:00:33] <jdh> thats why the current ones leak.
[16:00:46] <jdh> could use silicone
[16:01:00] <furrywolf> get a hollow punch set, a block of wood, and a hammer.
[16:01:06] <_methods> maybe try a sign shop
[16:01:07] <jdh> anyone have a laser?
[16:01:12] <_methods> on a vinyl cutter
[16:01:27] <_methods> might play hell on the knife though
[16:01:49] <_methods> i'm not sure how well neoprene cuts on laser
[16:01:52] <jdh> the holes are rg-178 size
[16:01:53] <Rab> It might need to be laminated with something a little less ductile, like paper.

[16:02:24] <Rab> Or self-adhesive vinyl, could peel off when finished.
[16:03:22] <furrywolf> bbl, work
[16:04:44] <ssi> jdh: not anymore :(
[16:04:48] <ssi> it would have done that nicely though
[16:04:52] <ssi> I used to cut a lot of silicone gaskets
[16:05:11] <_methods> ssi did you build your laser or buy?
[16:05:16] <ssi> built
[16:05:21] <ssi> I'm gonna build another one soon
[16:05:22] <_methods> openbuild?
[16:05:39] <ssi> no, just made it up as I went along :P
[16:05:43] <_methods> k
[16:05:58] <ssi> I started with a shapeoko kit with longer rails, used their carriages
[16:06:01] <ssi> it worked out pretty well
[16:06:03] <_methods> i'm not sure if i want to build a laser next or plasma table
[16:06:20] <ssi> I didn't have a height adjustable bed though, and I ended up wishing i did
[16:06:35] <ssi> it was fine for cutting thin stuff, but you need a lot of travel for thick material plus long focus lenses
[16:07:11] <_methods> you had 120w?
[16:07:14] <ssi> yeah
[16:07:23] <_methods> can you cut 3/4 ply with it?

[16:07:35] <ssi> not with the lenses I had, but with long enough focus yes
[16:07:53] <_methods> 7.5" lens?
[16:07:54] <ssi> i could cut 1/2" ply with a 3" lens, but it was right on the edge
[16:07:58] <_methods> or is tha tway too big
[16:08:03] <ssi> and if there was a nasty glue void it wouldn't cut

[16:09:02] <_methods> you get your lenses from II-VI
[16:09:03] <ssi> hm neoprene might be a bad idea actually
[16:09:05] <ssi> chlorinated
[16:09:14] <_methods> i was gonna say i think neoprene is bad to cut
[16:09:15] <ssi> I got my lenses from china :P
[16:09:41] <_methods> znse lenses?
[16:09:45] <ssi> yeah
[16:10:02] <_methods> how much are the 8"?
[16:10:05] <_methods> $400?
[16:10:12] <ssi> lol not from china
[16:10:16] <_methods> hmmm
[16:10:17] <ssi> nthey're all about the same price; probably around $50
[16:10:21] <_methods> wow
[16:10:22] <_methods> nice
[16:10:32] <_methods> how often you lose a lens?
[16:11:04] <ssi> I never lost one for any reason other than mishandling
[16:11:18] <_methods> you use gas assist?

[16:12:18] <_methods> not much power
[16:12:21] <ssi> no, not much

[17:14:16] <Rab> Guest35479, the OSE people don't seem to be out of the prototype stage. On their bill of materials, there's a line item: "Xylotex 4 Axis Drive Box" "$460"...that's going to be something like this:
http://xylotex.netfirms.com/OSCommerce/catalog/product_info.php?cPath=22&products_id=92&osCsid=da434ce2f555c759d96259d0abdbddfd
[17:14:38] <archivist> I make gears which are more regular
[17:15:19] <Rab> Guest35479, that's a complete drive system which hooks up to a computer parallel port.
[17:15:23] <dirty_d> taht sounds a lot easier
[17:15:48] <dirty_d> it seems like there isnt any 2.5d cam software for linyux thats even half way decent
[17:16:18] <dirty_d> ive resorted to writing gcode generating libraries and just coding parts
[17:16:24] <dirty_d> it kinda sucks though
[17:16:26] <skunkworks> ace converter (windows) dxf2gcode (both) and by hand
[17:16:44] <archivist> depends how you define decent and more important what you are making
[17:17:00] <dirty_d> just 2.5d stuff, no 3d
[17:18:39] <Guest35479> Hmmm... That looks completely different than what I have. I have the 4 stepper motors and a power supply and a mysterious circuit...
[17:19:00] <dr0w_> Speaking of Linux and CAM, I keep meaning to try HeeksCAM, anyone checked it out?
[17:19:14] <Rab> Guest35479, where did you get that hardware? Is there any branding on the "mysterious circuit"?
[17:19:20] <dirty_d> i just ran it in wine and it worked
[17:19:34] <dirty_d> but i didnt really do much
[17:19:34] <archivist> mysterious circuit is probably your breakout board which also has opto isolators
[17:19:56] <Rab> Guest35479, a photo might be worth a thousand words.
[17:20:57] <Guest35479> ok I'm starting to catch on. Thanks for everyone's patience. I've jsut figured out how to make fire so this is a tad challenging.
[17:22:01] <Rab> Guest35479, no worries.
[17:22:13] <archivist> like this example

[17:26:05] <Guest35479> Yes that's the hardware.
[17:26:53] <Rab> Guest35479, OK, pretty simple. You may need to build a cable to the computer's parallel port; page 5 shows the pinout.
[17:28:01] <Rab> In fact, that's what they're using:

[17:29:54] <Guest35479> Ummm quick question... my computer doesn't have a parrall port. So I'll need to go from the Monitor port to the parallel port?
[17:29:57] <Rab> From there, it should just be a matter of configuring the software. This is a fairly generic setup.
[17:30:22] <Rab> No, the monitor port will not work. You'll need a computer with a parallel port.
[17:30:39] * SpeedEvil ponders I2C-linuxcnc
[17:30:54] <SpeedEvil> you could in principle do it over DDC, I think.
[17:31:01] <SpeedEvil> But yes - parallel port would be rather saner
[17:31:03] <Rab> Guest35479, and USB-to-parallel converters will not work for this application.
[17:31:54] <Guest35479> So that's like where you would plug in a printer?
[17:32:05] <Rab> Right.
[17:32:36] <Guest35479> Does anyone have the instructions on how to build a time machine to 1993?
[17:32:54] <Rab> Yes, but they took the instructions with them.
[17:32:56] <SpeedEvil> Many motherboards come with printer ports
[17:33:15] <SpeedEvil> they're often not brought out to the rear panel
[17:33:37] <Guest35479> Hmmm... OK how powerful does this computer need to be? Can I go by one at goodwill?

[17:35:16] <Rab> Guest35479, this might give you a general idea:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Hardware_Requirements
[17:35:23] <dirty_d> you could use a parallel port PCI card, $10
[17:35:49] <SpeedEvil> Check if your motherboard has a parallel port header
[17:36:12] <SpeedEvil> Otherwise, pcie-printer ports are very inexpensve
[17:36:13] <Guest35479> Oh that looks like nothing Rab.

[17:38:14] <Rab> Guest35479, the hardware doesn't have to be extraordinarily fast, but it does need low latency for real-time processing, which is a separate issue. Sometimes fast computers will still have latency issues.
[17:38:14] <Guest35479> Ok. Stupid question. I have a laptop. Is there some sort of external thing a ma jig I can buy to remedy this?
[17:38:49] <Rab> Guest35479, any card slots on the laptop and which type?
[17:39:20] <Rab> A laptop's not generally a great choice, but some work.
[17:39:46] <SpeedEvil> Port replicators for laptops ccan be non-USB and work well
[17:39:48] <Guest35479> I have an unused spot for a dvd.
[17:39:51] <SpeedEvil> but it really varies a lot

[17:43:09] <dirty_d> then just use a usb to have the gui control it

[17:43:19] <dirty_d> i dont think they are too slow
[17:43:25] <SpeedEvil> pcw_home: It is certainly not too slow
[17:43:29] <archivist> usb is a bad idea
[17:43:30] <dirty_d> i think the higher end ones are 200MHz
[17:43:46] <SpeedEvil> There are ones with 200MHz single-cycle FPUs and really flexible PWM units
[17:43:48] <dirty_d> and then you no longer need to jump through hoops to acheive timing requirements
[17:44:00] <dirty_d> and you can use any pc
[17:44:12] <dirty_d> and you just need a $20 piece of external hardware
[17:44:21] <SpeedEvil> I'm not sure how amenable the stack is to porting to something small.
[17:44:37] <SpeedEvil> AIUI,for a generic solution, you need to put the entirety of HAL into it
[17:44:40] <SpeedEvil> which is quite large
[17:44:50] <dirty_d> yea
[17:45:03] <Rab> There's somebody who did that, I think for PIC32. It's not open source, he sells the dongle.
[17:45:10] <dirty_d> wouldnt it make the HAL unneccesary?
[17:45:10] <SpeedEvil> For any given machine - it's quite trivial computationally to do
[17:45:26] <SpeedEvil> dirty_d: No.
[17:45:48] <SpeedEvil> dirty_d: Either you accept the round-trip latency between the PC and the device, or you put HAL on the device in some form

[17:48:54] <archivist> a PC and a parallel port is pretty damned open
[17:49:51] <CaptHindsight> thinking about lost wax casting again the fastest, highest res and most accurate method is SLA (DLP or LCD) with a water soluble photopolymer, no heat is required so there's no thermal expansion of the mold during removal
[17:50:12] <dirty_d> i think if that architecture was used at the start of designing linuxcnc, it would have ended up simpler overall
[17:50:20] <Rab> Yeah, servo controllers seem to arise from the same calculus...if somebody is smart enough and does the work for a competent solution, they generally want to be paid for it.
[17:51:07] <archivist> servos have been driven off a parallel port too (not optimum but possible)
[17:51:09] <Rab> dirty_d, but it would depend on one specific peripheral. I think it's pretty neat that you can use FPGA boards, ethernet, whatever the market wants to provide.
[17:51:30] <cradek> if the linuxcnc architecture had been tied to a certain piece of non-commodity-pc hardware in 1993 it would be dead today
[17:52:05] <Rab> You would have been crazy not to use the parallel port in 1993. ^_^
[17:52:50] <dirty_d> the hardware would change along with the software
[17:52:50] <Rab> cradek, people would be searching for motherboards with an ISA slot.

[17:55:37] <Rab> dirty_d, I have two of those, so I encourage you to get cracking.
[17:55:40] <dirty_d> you have a plethora of hardware timers to use
[17:55:46] <cradek> the BBB is very cool, but is just a flash in the pan
[17:55:47] <dirty_d> me too
[17:56:16] <dirty_d> i already made a 3 axis controller, but it doesnt work with linuxcnc or gcode
[17:56:25] -!- Guest35479 has quit [Ping timeout: 246 seconds]
[17:56:28] <dirty_d> im lazy
[17:56:42] <archivist> rather lacking in memory
[17:57:25] <dirty_d> you dont need much for the motion control
[17:57:37] <Rab> dirty_d, here's a standalone project for BBB:
https://github.com/hzeller/beagleg
[17:57:38] <dirty_d> the pc would do 99% of the workload
[17:58:02] <ssi> dirty_d: you're just describing reprap-style drip fed motion control
[17:58:07] <ssi> which is very much not linuxcnc's aim
[17:58:14] <dirty_d> leave the gui and gcode processing to the PC and just let the external hardware coordinate motion
[17:58:50] <ssi> honestly BBB with hostmot fpga motion control would be a good solution,
[17:59:01] <ssi> but the sticking point seems to be that BBB doesn't have capable enough video hardware for the opengl preview
[17:59:29] <dirty_d> i think a laptop with a usb device is the ideal solution
[17:59:36] <ssi> I disagree :P
[17:59:40] <Rab> ssi, it's usable, but laggy.
[17:59:42] <ssi> laptops are expensive and the wrong solution
[17:59:51] <dirty_d> its portable so you can work on stuff at home and just bring it into the shop when you need to machine stuff
[18:00:53] <dirty_d> does linuxcnc control servo motors directly, or does it communicate with a servo controller?
[18:01:13] <CaptHindsight> didn't TI just release an ARM soc with the PRU's and a better GPU?
[18:01:24] <Rab> dirty_d, I think the answer is "yes"
[18:01:37] <dirty_d> both?
[18:02:25] <archivist> can handle proper servos and step dir types
[18:03:15] <CaptHindsight> http://www.ti.com/lsds/ti/arm/sitara_arm_cortex_a_processor/arm_cortex_a9_core/am437x_arm_cortex_a9/products.page?paramCriteria=no#p2103=1%203D
[18:03:34] <CaptHindsight> with 4 PRU's
[18:03:41] <Rab> dirty_d, I don't believe it would be possible to do servo control or other type of RT closed loop in LinuxCNC with the kind of abstraction you're talking about.
[18:03:47] <pcw_home> ugg powerVR again
[18:03:59] <dirty_d> Rab, i wouldn't think so either
[18:04:21] <CaptHindsight> http://www.ti.com/product/am4379
[18:04:35] <dirty_d> whats the typical interface to a servo controller?
[18:04:46] <dirty_d> like steppers have dir and step, what do you have with a servo?
[18:05:03] <CaptHindsight> analog +/-10V
[18:05:05] <pcw_home> if you want to run linuxcnc on a micro, that micro needs to run all of hal or you are just reinventing mach
[18:05:16] <Rab> For quasi-deterministic motion like steppers, you could just output step commands coupled with a calculated execution timestamp. The peripheral buffers the commands, and executes at the right time. I suspect that's how rt-stepper works.
[18:05:40] <dirty_d> Rab, thats what mine does
[18:05:44] <Rab> But you don't get any usable feedback.
[18:06:03] <dirty_d> well you can get feedback
[18:06:18] <SpeedEvil> It doesn't - quite - need to run all of HAL - it could run a 'compiled' subset. But in practice, that's going to be so much work to do, it probably does
[18:06:20] <dirty_d> tell it to step at x velocity until a switch or probe hits something, then stop, and report back the position
[18:06:44] <archivist> too late for geared motion
[18:07:05] <pcw_home> no realtime feedback to the control is not good for a profesional machine control
[18:07:20] -!- md-2 has quit [Quit: Leaving...]
[18:07:21] <dirty_d> but the external hardware is the control
[18:07:29] <dirty_d> the pc software is just a gui and gcode processor
[18:07:36] <pcw_home> Unless you implement all of hal you aint got much
[18:07:39] <dirty_d> thats how i would envision it
[18:07:53] <pcw_home> mach...
[18:07:59] <archivist> nope, the pc has the control and the inter linking
[18:08:12] <dirty_d> well i know it does now
[18:08:16] <archivist> and mach does not work too well
[18:08:22] <dirty_d> but im saying there isnt any reason it couldnt work like that
[18:08:40] <archivist> look at the problems mach users run into
[18:08:43] <CaptHindsight> http://www.ti.com/lsds/ti/arm/keystone/products.page these have a DSP and price tags >$100
[18:08:47] <skunkworks> There isn't... But then you need to move a ton of stuff to your external hardware...
[18:11:06] <dirty_d> true, its a lot of work
[18:11:56] <archivist> we get a dreamer suggesting similar every few months
[18:12:06] <dirty_d> but once its done it works perfectly forever with way better realtime performance tahn youd ever get with a pc
[18:12:53] <dirty_d> if its ported to run on arm microcontrollers , then it would be pretty easy to move it to better ones as they appear in the market
[18:13:28] <pcw_home> Still to slow if you do anything mildly complex
[18:14:06] <dirty_d> whats complex?
[18:14:11] <jdh> tp and queueing
[18:14:16] <pcw_home> even 1.8 GHz atoms are too slow for some common linuxcnc uses (large classic ladder and servo thread faster than 2 KHz)
[18:14:16] <archivist> a hobbing machine
[18:14:32] <dirty_d> whats tp?

[18:14:43] <pcw_home> trajectory planning
[18:14:47] <archivist> trajectory planner
[18:14:53] <dirty_d> the pc would do that
[18:15:05] <archivist> exactly it has to be realtime
[18:15:09] <pcw_home> mach...
[18:15:11] <dirty_d> the external hardware only has to coordinate motion
[18:15:25] <dirty_d> no, the trajectory is deterministic
[18:15:25] <CaptHindsight> the other piece that people gloss over when imagining their new machine controller is all the flexibility, support and who is going to port to new platforms
[18:15:31] <archivist> wrong
[18:15:42] <dirty_d> archivist, i dont understand then
[18:15:49] <dirty_d> why isnt it deterministic?
[18:15:50] <archivist> load affects the planner
[18:16:49] <SpeedEvil> CaptHindsight: And what happens when the microcontroller of choice dies
[18:16:58] <dirty_d> im not following, i know the power to the servos etc needs to be realtime and non-deterministic, but your planned path is deterministic
[18:16:59] <SpeedEvil> (becomes out of stock)
[18:17:14] <SpeedEvil> dirty_d: Only if you have no feedback
[18:17:29] <archivist> dirty_d, no because of realtime feedback
[18:17:30] <pcw_home> or adaptive feed
[18:17:50] <_methods> http://laughingsquid.com/relatives-dress-a-deceased-man-as-green-lantern-and-stand-him-up-at-his-wake-because-he-was-a-hero-to-them/
[18:18:48] <Rab> The most common hobby/home shop use cases don't require feedback, though.
[18:18:58] <archivist> dirty_d, you have to see a geared operation like screw cutting or tapping to see it in action
[18:19:16] <_methods> just use an arduino and grbl
[18:19:17] <_methods> lol
[18:19:30] <_methods> like a bawse
[18:19:37] <dirty_d> what im thinking is that the PC software reads your gcode and calculates a trajectory based on the max velocity and acceleration youve set up, then tells the external hardware to execute that plan, and follow it as closeley as possible using feedback
[18:19:42] <dirty_d> or not in the case of steppers
[18:19:53] <skunkworks> feed override...
[18:19:55] <dirty_d> but the heavy calculations would have already been done on the PC
[18:20:01] <dirty_d> whats feed override
[18:20:11] <renesis> faster
[18:20:22] <archivist> dirty_d, when screw cutting on a lathe X has to respond to the spindle speed
[18:20:31] <archivist> I mean Z
[18:20:46] <skunkworks> or x.. (linuxcnc doesn't care... ;) )
[18:20:51] <dirty_d> i would consider that motion control and the responsibility of the external hardware
[18:20:56] <pcw_home> Buffered solutions are common and exist but carry many disadvantages
[18:21:00] <archivist> true, helical path :)
[18:21:15] <skunkworks> :)
[18:21:53] <archivist> dirty_d, but you happen to be wrong for motion under full control with feedback
[18:21:58] <dirty_d> the pc would tell the hardware to move the x axis a number of units for every number of radians on the spindle
[18:22:16] <SpeedEvil> That works for one case.
[18:22:21] <archivist> you are thinking open loop
[18:22:40] <dirty_d> archivist, no im thinking with feedback from the servos or encoders or whatever
[18:22:44] <archivist> closed loop is better
[18:22:48] <dirty_d> right
[18:23:00] <archivist> the loop is in the control
[18:23:05] <dirty_d> right

[18:30:20] <Cromaglious> hmm older 3040
[18:30:21] <CaptHindsight> most vendors moved to PC for CNC control years ago, they just don't advertise the fact
[18:30:41] <renesis> capthindsight: its kind of obvious when you see the controllers, tho
[18:31:20] <renesis> like, theres an operating system there, its not just a bare bones UI looking all 80s vectorish
[18:31:20] <Loetmichel> Cromaglious: 6040 if you mean mine ;-)
[18:31:23] <CaptHindsight> $20k for a cnc controller is OK, but not for a PC

[18:56:26] <__rob> yea, I'm sure there are complexities

[19:51:20] * _methods stays out of religious wars
[19:51:29] <Connor> So, my neighbor, instead of cutting the branch hanging over my power line like I asked... stuck a 2x4 under it to get it off my line.. Which was nice.. I didn't even think of it.. but.. I'm a tad concerned because wind is suppose to get really bad tonight... I don't think the 2x4 is going to help much...
[19:52:10] <jdh> it is going to fall and hurt something
[19:52:38] -!- sumpfralle has quit [Client Quit]
[19:52:51] <Connor> No. But if the wind picks up.. it could lift the branch off of it, or something and the branch can come down ontop of my line again, only with more weight and force.. and POOF no power.
[19:53:09] <PetefromTn_> cut the fucker down..
[19:53:22] <CaptHindsight> I once cut a tree down in my neighbors yard to prevent that
[19:53:34] <CaptHindsight> they didn't mind if I did the labor
[19:54:10] <Connor> I really have no way to do it safely. All I have is a Ryobi 18v chain saw.. and I would have to be on a ladder to get to the branch.
[19:54:51] <PetefromTn_> MY japanese pine tree has loaded up with ice and several of the branches fell down onto my power leads to my house the other night. Happened at 2AM.
[19:55:00] <Connor> the last thing me or wife needs is me in the hospital with broken arm, leg or neck..
[19:55:14] <PetefromTn_> I went out there with a long piece of wood and started whacking on the ice...
[19:55:32] <PetefromTn_> the needles and branches were so cold they mostly just shattered and broke
[19:55:51] <Connor> Yea.. my power head has been pulled through the roof about 2" or so...
[19:55:52] <PetefromTn_> now that branch is in it's normal position again only with a few less ends
[19:55:59] <Connor> before this winter ice stuff..
[19:56:08] <PetefromTn_> the rest of the tree is in kind of bad shape now
[19:56:26] <PetefromTn_> I MAY wind up having to climb that thing and start cutting it down from the top down...
[19:56:41] <Connor> Ick
[19:57:23] <PetefromTn_> That will be the third of four trees on my property that have been killed by weather here. All I have left is one bradford Pair tree in the front yard and shrubs now if this one dies...
[19:57:45] <PetefromTn_> One of the main reasons I bought this house was a beautiful weeping willow tree in the back yard
[19:57:57] <PetefromTn_> that thing lasted not even one year after we moved in.

[19:58:07] <_methods> that sux
[19:58:10] <PetefromTn_> big lightning strike ripped it in half..
[19:58:36] <PetefromTn_> yeah I really like those trees even tho they are a pain in the ass to clean under...
[20:01:42] <Cromaglious> as a kid my grandpa had one in his back yard, my brother and I would do the tarzan thing swinging on the branches
[20:02:36] <PetefromTn_> yup it is my Grandmother's favorite tree too. She insisted my grandfather plant one on every piece of property they ever owned LOL...
[20:11:38] <Tom_itx> Connor go out in the middle of the night and cut the branch off
[20:12:21] <Tom_itx> PetefromTn_ we had lightening hit a tree out front... it ploughed the ground at the base of the tree
[20:14:53] <Tom_itx> i think the tree will live but the bark is peeling on one side
[20:15:33] <PetefromTn_> yeah that is kind of what happened to this tree..
[20:15:57] <PetefromTn_> It actually looked okay from the outside except for one of the main spars out of two had been sheared off.
[20:16:08] <Tom_itx> usually you can count between sight and sound but not on this one :D
[20:16:11] <PetefromTn_> but when we cut the thing down it was pretty well destroyed inside
[20:16:25] <PetefromTn_> Oh yeah it shook our whole house LOL
[20:16:40] <PetefromTn_> sounded like a bomb went off or something
[20:16:56] <PetefromTn_> the tree was maybe fifteen yards from my back porch
[20:17:17] <Tom_itx> about the same here
[20:17:24] <Tom_itx> if that far
[20:17:56] <Tom_itx> ok i think i've gathered enough crap i can get this spindle working today hopefully
[20:18:38] <Tom_itx> i need to test the relay outputs though to make sure one is firing before the other

[20:18:49] <Tom_itx> fwd is
[20:18:52] <PetefromTn_> ah
[20:19:02] <Tom_itx> and i was gonna add PID just because...
[20:19:11] <PetefromTn_> its so cold out in the shop I have not even bothered to go out there today.
[20:19:16] <Tom_itx> it's not needed but it's a learning thing with me
[20:19:21] <PetefromTn_> my kids are off apparenlty all week now.
[20:19:33] <Tom_itx> netflix time
[20:19:45] <Tom_itx> do redbox?
[20:19:54] <PetefromTn_> yeah I have been sitting here doing some Cad drawings and design work
[20:20:01] <PetefromTn_> yeah we do redbox
[20:20:07] <Tom_itx> 727272 to SHOWTME and get a free one
[20:20:08] <PetefromTn_> even got a free one waiting
[20:20:10] <Tom_itx> that or MOVIETIME
[20:20:17] <Tom_itx> i forget
[20:20:27] <PetefromTn_> did not know that
[20:20:40] <PetefromTn_> but it is still pretty shitty and icy here on the roads
[20:20:40] <Tom_itx> we get those from time to time
[20:20:46] <PetefromTn_> been kinda keeping inside
[20:21:12] <PetefromTn_> Don't really feel like cracking up my truck just to get some movies hehe
[20:21:17] <Tom_itx> got 4 phones so i got 4 free rentals :D
[20:21:31] <PetefromTn_> Oh yeah you can do it more than once heh
[20:21:40] <PetefromTn_> we have three phones here HMmm

[20:25:35] <Tom_itx> caps
[20:25:38] <PetefromTn_> you just text movietime to 727272?
[20:25:45] <Tom_itx> no just the opposite
[20:26:10] <PetefromTn_> do they kill your damn phone with offers and junk after that?
[20:26:25] <Tom_itx> i dunno i didn't do it on mine :D
[20:26:31] <Tom_itx> i don't think so
[20:26:37] <Tom_itx> they haven't yet
[20:26:40] <PetefromTn_> LOL I see what you did there....
[20:26:51] <Tom_itx> she's had 4 at once before
[20:27:15] <Tom_itx> so use 3 cc and do the math there
[20:27:29] <PetefromTn_> http://chattanooga.craigslist.org/tld/4868688785.html This looks like a sweet machine....
[20:28:12] <Tom_itx> nice size
[20:28:20] <Rab> Watch out, those codes are only good for a day and you have to give a CC at the kiosk. If you return late, you automatically get charged.
[20:28:34] <Tom_itx> right
[20:28:41] <Rab> I don't remember if "1 day" means 24 hours, or next day at midnight, or what.
[20:28:45] <Tom_itx> but knowing that going in just return it
[20:29:13] <Tom_itx> you need a cc at the kiosk anyway
[20:29:23] <PetefromTn_> yeah we do it all the time.. have paid late fees several times too heh
[20:30:01] <Tom_itx> that one you have a week to use
[20:30:03] <PetefromTn_> It's kind of a Friday thing for us around here.. get the newest releases and wind up keeping them til' sunday morning to watch them hehe

[20:42:48] <PetefromTn_> there is a build thread somwhere that a guy took a Feeler version and built a nice XY slide table that mounted on the large dovetail on the same basic machine. Looked pretty cool....
[20:44:05] <jdh> its about 5miles from my house
[20:44:48] <jdh> awfully big for such a small lathe
[20:47:33] <oceax> I want to do rigid tapping, but i have a 2.2kw vfd spindle => no torque at low rpm. Would buying mesa 7i77, a servo motor and create a belt drive to my 2.2kw spindle be a good solution?

[20:57:33] <PCW> Have you tried tapping with the spindle?
[20:59:51] <oceax> No i have only done tapping by hand before. But from what i have read online it should not work well with my type of spindle.
[21:01:35] <furrywolf> speaking of rigid tapping, can linuxcnc do single-point threading on a mill? that is, set the spindle speed down really low, and put an internal threading in the chuck, and synchronize its movement down into the workpiece? will need to synchronize both the z travel (easy, that's just rigid tapping) and helically (harder?).
[21:02:54] <rob_h> wouldt one just thread mill it instead?
[21:03:10] <furrywolf> you could, yes.
[21:03:20] <rob_h> i know not as fun tho right
[21:03:37] <furrywolf> right. :P
[21:04:21] <furrywolf> anyway, the question is "can linuxcnc do", not "is it the best way" :)
[21:04:41] <rob_h> i bet it could not alot it cant if u put your mind to it

[21:05:23] <FinboySlick> You may need to write a patch though ;)
[21:05:42] <rob_h> it dosnt clean up the chips too well after its self tho thats for sure i always end up doing that
[21:05:49] <CaptHindsight> or very creative Gcode
[21:06:30] <FinboySlick> rob_h: OpenCV, multi-axis arm, vacuum... You're set.

[21:09:09] <CaptHindsight> spent the afternoon talking to airbrush manufacturers, I feel the same now after standing in line for 2 hours at the DMV
[21:09:11] <furrywolf> single-point threading with the mill would require either a very slow spindle or pretty fast axis acceleration... not sure my machine could do it anyway. heh.

[21:10:46] <furrywolf> airbrush manufacturers are that bad, eh?
[21:11:57] <furrywolf> because after the dmv, I usually feel like killing people.
[21:12:10] <CaptHindsight> 99% of there customers questions must be "How come every time I press the trigger it squirts in my eyes?"
[21:12:28] <CaptHindsight> "are you holding it backwards?"
[21:12:40] <furrywolf> lol
[21:12:59] <furrywolf> or some variant of "how come my art doesn't sell?" "because you suck."
[21:13:13] <CaptHindsight> must be the brush :)

[21:50:33] <jims> Any takers?

[21:52:19] <micges> who knows will answer
[21:52:51] -!- FinboySlick has quit [Quit: Leaving.]
[21:54:25] <jims> In Axis, my display shows the tool rotating about the "point of the cone" instead of tracing a path about the axis of rotation, that is the X axis. Do you know of a setting to change this?
[21:56:23] <jims> There is a YouTube video doing just what I want, so I know it's possible, but I am stumped.
[21:56:59] <micges> jims:

[21:57:06] <micges> look for GEOMETRY
[21:58:14] <jims> I set that to GEOMETRY = XYZA, but no luck.
