[00:39:49] <skunkworks__> Aero-Tec: in and out - ask away.
[00:40:10] <Aero-Tec> when you ran the sim
[00:40:21] <Aero-Tec> you did it with your mill setup
[00:40:23] <Aero-Tec> right?
[00:40:38] <Aero-Tec> it was not set to lathe
[00:41:19] <Aero-Tec> the problem was every tool change in lathe seams to need a reset of s and f
[00:42:06] <Aero-Tec> so it you da a tool change and do not have not set s and f it will complain and stop running the code
[00:42:31] <Aero-Tec> oops bad typing
[00:44:11] <Aero-Tec> I change it by accident the first tool change and did not know what I did to fix it, but it would then complain after the next tool change
[00:44:25] <Aero-Tec> I was trying every thing
[00:46:22] <Aero-Tec> finally I remed out the F300, it then said something about 0 feed, then it twigged, lincnc does not carry the F and S from the tool before to the next tool
[00:46:29] <jymmm> Hmmm, I need to build a hot box of some sort.
[00:46:37] <Aero-Tec> it has to be set for each tool change
[00:47:15] <Aero-Tec> not sure if the mill is the same
[00:47:35] <Aero-Tec> if so then it is funny the sim ran fine
[00:47:49] <Aero-Tec> hot box?
[00:48:01] <Aero-Tec> and we are not talking girls here right?
[00:48:03] <Aero-Tec> lol
[00:48:14] <jymmm> I WISH =)
[00:48:23] <Aero-Tec> what is a hot box
[00:48:34] <jymmm> Build your own girl hot box... mine will be mute =)
[00:48:58] <jymmm> Like a BIG toaster oven, but only maintain between 80 - 140 F
[00:49:05] <jymmm> 24/7
[00:49:20] <jymmm> kinda a dry heat
[00:49:39] <Aero-Tec> what for welding rod?
[00:49:48] <jymmm> Could probably just use a light bulb if I think about it.
[00:50:00] <jymmm> No, to dry things out
[00:50:02] <Aero-Tec> toaster over works good for them
[00:50:14] <jymmm> but not down to 120F
[00:50:21] <Aero-Tec> how big?
[00:50:37] <jymmm> maybe 2ft cubed
[00:51:02] <jymmm> maybe 3ft cubed
[00:51:19] <Aero-Tec> halogen light would work for sure
[00:51:27] <Aero-Tec> may get to hot
[00:51:31] -!- Thetawaves [Thetawaves!~Thetawave@7-139-42-72.gci.net] has joined #linuxcnc
[00:51:44] <jymmm> But since it'll run 24/7, want no heat to escape to conserve electricity as much as possible
[00:52:13] <Aero-Tec> 24/7?
[00:52:22] <Aero-Tec> that are you drying out?
[00:52:27] <jymmm> 24 hours a day, 7 days a week
[00:52:34] <Aero-Tec> you will need air to move some
[00:52:57] <jymmm> I have muffin fans
[00:53:28] <Aero-Tec> I know what 24/7 means, just surprised you would need to run that hard
[00:53:44] <jymmm> Well, it's not much heat if you think about it
[00:53:46] <pfred1> yup real rod drier boxes just have light bulbs in them
[00:54:24] <jymmm> thermostat controlled dimmer =)
[00:55:05] <Thetawaves> http://hardware.slashdot.org/story/12/05/23/2030235/darpa-pays-35-million-for-new-techshops-and-secret-reconfigurable-factories?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Slashdot%2Fslashdot+%28Slashdot%29
[00:55:29] <Thetawaves> that's gonna be a hard one
[00:55:47] <Aero-Tec> if what your drying is like rods with very little water then you may not need the fans, would be easy to keep warm/hot
[00:56:05] <jymmm> I'll have to see what cheap sheet metal there is. It may only be 140F, but running 24/7 I want fire containment!
[00:56:31] <Aero-Tec> but if your driving off allot of water you will need something like a fruit dryer
[00:57:03] <Thetawaves> jymmm, my supply of al sheet is extremely cheap
[00:57:15] <Thetawaves> cut fee costs more than the sheet
[00:57:20] <jymmm> Thetawaves: define cheap?
[00:57:34] <jymmm> well, I'm taking cut with scissors thin
[00:57:38] <jymmm> talking
[00:57:39] <Thetawaves> i think 40$ for 4x4'
[00:57:55] <pfred1> strip old hot water heaters
[00:58:08] <pfred1> skin them suckers get a lot of sheet metal
[00:58:17] <jymmm> Yeah, that's expensive to cover 54 sq ft
[00:58:31] <Aero-Tec> so with lincnc, do you have to set the S and F for each tool change?
[00:58:46] <jymmm> pfred1: Can't, the metal recyclers snatch them up quick!
[00:59:22] <Aero-Tec> it looks like it for the lathe
[00:59:27] <pfred1> jymmm you live in cali don't you?
[00:59:35] <jymmm> pfred1: yeah
[00:59:39] <Aero-Tec> but is the mill the same?
[00:59:55] <pfred1> jymmm yeah I'm hoping the country gives that state back to mexico pretty soon
[01:00:13] <pfred1> place is mexico anymore anyways might as well be in name too
[01:00:33] <jymmm> pfred1: lol
[01:00:52] <pfred1> well it was kinda sleezy how we got the place
[01:01:24] <pfred1> whats fair is fair give it back!
[01:01:45] <jymmm> lol
[01:02:38] <Aero-Tec> unless you move you would become a mexican
[01:03:03] <Aero-Tec> not sure if being a mexican is so good
[01:03:14] <Aero-Tec> that is why they come to the US
[01:04:12] <Aero-Tec> anyways
[01:04:25] <Aero-Tec> do you guys run EMC
[01:04:37] <Aero-Tec> or linux cnc as they call it now
[01:04:54] <Tom_itx> ok, no smoke... initial stepper test worked on the old controller
[01:05:06] <Tom_itx> time to reinstall ubuntu
[01:05:15] <pfred1> Aero-Tec it is like anything else some mexicans do OK for themselves
[01:05:37] <Aero-Tec> you know electronics runs on smoke
[01:05:40] <pfred1> they're not the ones you run into in the USA though
[01:05:52] <Aero-Tec> you let the smoke out and it stops working
[01:06:33] <pfred1> it seems to me that Ubuntu is targeting the mobile market anymore
[01:06:45] <pfred1> which I think for them is a smart move
[01:07:04] <r00t4rd3d> http://i.imgur.com/8p2PJ.jpg
[01:07:08] <ReadError> soooo
[01:07:14] <ReadError> ordered a camera for my mill
[01:07:17] <ReadError> hope it works
[01:07:49] <Aero-Tec> cool ride
[01:08:04] -!- trung [trung!~trung@ec2-23-23-179-94.compute-1.amazonaws.com] has joined #linuxcnc
[01:08:07] <pfred1> but I don't think any desktop users sticking with ubuntu are really thinking in advance
[01:08:12] <Aero-Tec> I have one of them motors, but have not put it on the bike yet
[01:09:26] <Aero-Tec> with EMC, lathe, are you forced to reset the S and F
[01:09:40] <Aero-Tec> or is there some sort of setting for that?
[01:09:40] <r00t4rd3d> how fast you think that goes?
[01:09:43] <r00t4rd3d> 80cc
[01:10:40] <Aero-Tec> that would depend on the gearing, the size of guy on it and if it is going up hill or down
[01:11:07] <Aero-Tec> I would guess it would hit 30 MPH
[01:11:07] <r00t4rd3d> im 150 and you can see the gear ratio
[01:11:22] <r00t4rd3d> 45-50
[01:11:34] <Aero-Tec> thats good
[01:11:44] <Aero-Tec> but will it clime hills?
[01:11:50] <r00t4rd3d> im good with 2 stroke small engines too
[01:11:57] <r00t4rd3d> rock and roll up them
[01:12:00] <Aero-Tec> me too
[01:12:18] <Aero-Tec> what kind of hills?
[01:12:40] <r00t4rd3d> the speed limit on my road is 45 and i can pass cars on the right
[01:12:54] <r00t4rd3d> up a big hill
[01:12:55] <Aero-Tec> in the flat lands what they call mountain we where I live call bumps

[01:13:28] <Aero-Tec> I live in the rockies
[01:13:34] <Aero-Tec> deep in them
[01:13:47] <Aero-Tec> we got hills every where
[01:14:15] <r00t4rd3d> i live by the Adirondacks
[01:14:25] <r00t4rd3d> 45min
[01:14:34] <Aero-Tec> never heard of them
[01:14:49] <Aero-Tec> where is that?
[01:14:58] <r00t4rd3d> east coast usa
[01:15:10] <Aero-Tec> ok

[01:15:18] <Tom_itx> smoky hills?
[01:15:20] <Aero-Tec> I live west coast Canada
[01:15:23] <Tom_itx> smokey*
[01:15:45] <Tom_itx> appilachian mountians?
[01:15:48] <r00t4rd3d> im smoked out
[01:16:41] <Aero-Tec> I keep asking about Gcode and the S and F
[01:16:52] <Tom_itx> what about it?
[01:16:53] <Aero-Tec> not getting any replyies
[01:17:08] <Aero-Tec> in my Gcode on the lathe
[01:17:22] <Aero-Tec> every tool change I have to reset F and S
[01:17:31] <Aero-Tec> is that a setting?
[01:17:44] <Aero-Tec> also is it the same with the mill?
[01:17:45] <Tom_itx> those are modal commands i believe
[01:17:49] <Tom_itx> yes
[01:17:59] <skunkworks__> Aero-Tec: I used sim lathe...
[01:18:06] <Tom_itx> T1 M6 F100 S2000
[01:18:15] -!- Nick001 [Nick001!~Nick001@plns-64-111-156-70-pppoe.dsl.plns.epix.net] has joined #linuxcnc
[01:18:21] <Aero-Tec> so why did the sim not stop when S and F were not reset?
[01:18:38] <Tom_itx> i sim on real steel
[01:18:44] <skunkworks__> I don't know...
[01:19:43] <ReadError> http://www.amazon.com/dp/B004M8SQ6Q/ref=pe_175190_21431760_A1_cs_sce_dp_1
[01:19:49] <skunkworks__> funny thing.. I don't think the spindle shut off for the tool changes.. Let me check..
[01:19:51] <Aero-Tec> anyway, it took some time and had a ton of interruptions, but I did track down the gcode problem
[01:21:14] <Tom_itx> http://linuxcnc.org/docs/html/gcode.html
[01:21:17] <Tom_itx> yes they are modal
[01:22:44] <Aero-Tec> one other thing I would like to know
[01:23:13] <Aero-Tec> tool length comp and tool rad comp, do they need to be turned on for lathe?
[01:23:22] <Aero-Tec> that is a mill thing is it not?
[01:23:54] <Tom_itx> i believe they can be but i'm not positive
[01:24:10] <Aero-Tec> the lathe will still use the tool table no matter if the comp is on or off, right?
[01:24:12] <Tom_itx> those offsets acount for wear
[01:24:16] <Tom_itx> etc
[01:24:19] <jymmm> pfred1: How long do you think it would take to stablize and heat a cubic meter box with a 40-80 watt lightbulb that's well insulated?
[01:24:38] <Tom_itx> 2 min
[01:24:47] <pfred1> I don
[01:24:49] <skunkworks__> Aero-Tec: yes- sim doesn't turn off the spindle. that is probably why it worked.
[01:24:51] <jymmm> sorry to 150F
[01:24:58] <pfred1> I don't know the pro rod driers use 100 watt bulbs
[01:25:00] <Tom_itx> 4 min
[01:25:18] <jymmm> pfred1: they get to 150f?
[01:25:27] <Aero-Tec> is that a Gcode setting?
[01:25:29] <Tom_itx> jymmm at sea level or on a mountain top?
[01:25:29] <pfred1> beats me they keep rods dry though
[01:25:39] <jymmm> pfred1: heh
[01:25:46] <Aero-Tec> EMC has way more Gcode things then mach
[01:25:56] <pfred1> mach is abandonware
[01:25:57] <jymmm> Tom_itx: 200ft
[01:26:08] <pfred1> the lead dev retired
[01:26:26] <Aero-Tec> just saying I am used to Mach
[01:26:35] <ReadError> its MACK
[01:26:39] <ReadError> ;p
[01:26:49] -!- toastydeath has quit [Read error: Connection reset by peer]
[01:26:51] <Aero-Tec> and programing EMC is very different
[01:27:12] <pfred1> yeah emc is almost like real software
[01:27:22] <Tom_itx> it's not that bad
[01:27:30] <Tom_itx> my post worked fine on it
[01:27:45] <Aero-Tec> Have to learn some new codes and learn EMC way of doing things
[01:28:16] <Aero-Tec> not complaining, just wanting to know
[01:28:40] <Tom_itx> it's been a long time since i ran a lathe so i forget about cutter comp
[01:28:43] <Aero-Tec> so is there a gcode for the spindle turning off for tool changes?
[01:28:46] <Tom_itx> err length and diameter
[01:28:48] -!- toastydeath [toastydeath!toastydeat@c-69-140-223-139.hsd1.md.comcast.net] has joined #linuxcnc
[01:28:58] <Tom_itx> sure is
[01:29:17] <Aero-Tec> in mill turning off spindle is needed
[01:29:32] <Aero-Tec> but in lathe, not so much
[01:29:36] <Tom_itx> M5
[01:29:54] <Aero-Tec> M5 turns off spindle
[01:29:55] <Tom_itx> also M9 to turn coolant off
[01:30:17] <Aero-Tec> but as far as I know does not effect if it turns off for tool changes
[01:30:39] <skunkworks__> Aero-Tec: in the ini - add TOOL_CHANGE_WITH_SPINDLE_ON = 1 in the [EMCIO] section. then the spindle stays on
[01:30:54] <Aero-Tec> cool
[01:30:56] <Aero-Tec> thanks
[01:32:07] <Tom_itx> that's kinda not safe
[01:32:17] <skunkworks__> for a lathe - that is pretty normal
[01:32:26] <Tom_itx> i suppose if you're drilling and tapping it may be ok
[01:33:08] <Tom_itx> on the lathe does it allow you to set an upper spindle limit?
[01:33:18] <Tom_itx> so you don't throw your bar across the room
[01:33:24] <Tom_itx> on constant surface speed mode

[01:42:17] <pfred1> mine are getting on my bird feeder again the only way I can see is they're dropping like 20 feet out of a tree onto it

[01:51:16] <skunkworks__> Tom_itx: yes - css lets you enter limits
[02:12:36] <skunkworks__> Aero-Tec: linuxcnc is very configurable - which makes it complex. (don't be afraid of it) ;)
[02:13:54] <pfred1> skunkworks__ it is complex because of something Don Johnson said in a movie once, nothing starts out complicated, it just gets that way ...
[02:15:35] <pfred1> but an alumni of mine said this first too "Unix is simple. It just takes a genius to understand its simplicity." – Dennis Ritchie

[03:21:44] <Valen> they seem to think its super important
[03:21:52] <ScribbleJ> Why would LibreOffice lose the ability to open word documents?
[03:22:40] <pfred1> we'll have to wait and see if it is still around in a couple of years
[03:23:05] * pfred1 still has his Star Office CD ...
[03:23:23] <pfred1> but no one here even knows what that is most likely
[03:23:40] <Valen> i didn't think star office lived untill there were CDs
[03:23:51] <pfred1> I have word perfect for linus too :P
[03:23:57] <pfred1> linux even
[03:24:42] <pfred1> I still use the fonts off that CD from time to time ...
[03:25:30] <pfred1> X Window fonts are kind of a running joke
[03:25:44] <Valen> i dont really notice fonts
[03:25:51] <pfred1> I do
[03:26:48] <pfred1> Valen the X Window Consortium is looking for people like you to carry the torch
[03:27:03] <pfred1> because I think they're all blind
[03:27:17] <Valen> lol
[03:27:32] <pfred1> xfontsel is one depressing program
[03:27:45] <Tom_itx> do i need to have the .xml file with the .bit file?
[03:28:24] <pcw_home> for pncconf, yes
[03:28:52] <Tom_itx> i may need to get the 7i47 from you again
[03:28:58] <pfred1> whoever said that xml was human readable doesn't read very good materials
[03:29:02] <Tom_itx> i'll check tomorrow to see if i have it somewhere
[03:29:36] <Tom_itx> i'm fairly sure i do
[03:32:49] <pfred1> is it just me or are people who comment on YouTube videos really of sub average intelligence?
[03:33:05] <ScribbleJ> Depends on the video.
[03:33:42] <Valen> i generally don't comment, does that mean i'm generally smarter?
[03:33:53] <pfred1> ScribbleJ ah yes I believe you're right the ones that attract more commenters do seem to attract the bottom feeders

[03:35:51] <ScribbleJ> So... speaking of sub average intelligence, I'm totally new to all this and not too bright to boot. Is there some good guide somewhere you guys know of that could help me figure out what milling bits to use under what circumstances?
[03:35:53] <pfred1> like check out this scintillating conversation I've been having over there http://pastebin.com/uzicxsm3
[03:36:04] <pfred1> they want to invent plants that eat CO2
[03:36:25] <ScribbleJ> That's brilliant! I'll get to it right after I'm done inventing farm animals that can produce methane.
[03:36:59] <pfred1> I mean can you believe it?

[05:33:07] <toner> <Valen> i *think* what the guy is wanting is airborne plankton
[05:33:15] <toner> there's all kinds of yeast and other stuff floating around, though
[05:33:48] <Valen> nothing that i know thats actually boyant though
[05:33:58] <toner> ah
[05:34:02] <Valen> i wonder if you could do that
[05:34:04] <toner> I didn't actually read the link ;)
[05:34:10] <Valen> bit of hydrogen is easy to come by
[05:34:16] <toner> I'm sure it's possible
[05:34:24] <toner> a thin balloon with warm air inside will float
[05:34:25] <Valen> i wonder if it scales down though
[05:34:36] <Valen> surface area vs volume
[05:34:39] <toner> I bet it could
[05:34:46] <Valen> mmm i dunno
[05:34:49] <toner> those little spiders have no problem catching a breeze and taking off
[05:34:59] <Valen> thats still not boyancy
[05:35:00] <toner> but that's different
[05:35:01] <toner> right
[05:35:09] <Valen> thats flying not floating
[05:35:13] <toner> hehe
[05:35:29] <toner> well, if you can form a balloon with a thin enough wall
[05:35:42] <toner> a little bit of heat or lighter gas will lift it
[05:35:49] <Valen> thing is you need to have enough cellular widgets to make said ballon
[05:35:56] <Valen> then the balloon needs to lift said widgets
[05:36:15] <toner> I'm sure there are plenty of organic structures that would be suitable
[05:36:30] * toner has no clue how to engineer one
[05:36:36] <Valen> most cell walls are lipids, which aren't going to be that light
[05:36:43] <toner> but, such a thing could exist
[05:36:45] <Valen> plankton and stuff make shell type walls
[05:36:55] <toner> not so light, but thin and strong
[05:37:01] <Valen> I'm just wondering how small it could be
[05:37:11] <Valen> on venus i can see it working
[05:37:12] <toner> yeah, that's an interesting question
[05:37:25] <Valen> lots more atmosphere to work with there
[05:37:39] <Valen> a cubic meter of air only weighs something like 1.4kg
[05:37:42] <toner> heh
[05:38:44] <Valen> now look at a helium balloon
[05:38:59] <Valen> see how much it weighs and how big it needs to be to lift off
[05:39:35] <Valen> as you reduce the size of the balloon the volume shrinks with a ^3 in it, but the surface area of the balloon only shrinks with a ^2
[05:41:00] <Valen> perhaps something the size of a golf ball might work
[05:41:07] <Valen> or a bit smaller
[05:41:18] <Valen> some kind of multi celled organism I think
[05:41:30] <Valen> coat the outside in photosynthetic stuff
[05:41:55] <Valen> when it gets to baseball size it'll start budding off other ones that seperate when they get to golfball size
[05:42:46] <Valen> sounds almost cute
[05:42:51] <Valen> till it blots out the sun
[05:43:04] <Valen> also a fire would be pretty friggin epic
[05:43:21] <Valen> (assuming your watching from a safe distance, like the moon)
[05:43:35] <Valen> i feel a short story of a sci-fi nature lol

[07:08:58] <toner> Valen: buckminster fuller thought about the other extreme of that, though
[07:09:00] <toner> neat idea
[07:09:09] <toner> basically you build a really, really big geodesic sphere
[07:09:16] <toner> with some kind of membrane around it
[07:10:05] <toner> and if you get the ratio of wall-thickness/interior-volume good enough, you can keep the inside like 1 deg C warmer than the outside and the whole thing floats
[07:10:08] * toner likes this
[07:11:57] <toner> I guess it's basically like a hot-air balloon
[07:13:32] <Valen> by definition ;->
[07:13:47] <Valen> you could be snarky and call it a warm air balloon
[07:13:56] <toner> hehe
[07:14:04] <Valen> be pretty restricted where it could go though
[07:14:11] <toner> yeah
[07:14:12] <Valen> crusing the tropics would suck
[07:14:57] <toner> it doesn't really make sense to make something that large if gravity forces you to live on the bottom portion of it :P
[07:15:09] <Valen> not that big i believe
[07:15:19] <Valen> somebody was looking at it again recently
[07:15:25] <toner> hm, yeah I guess hot air balloons are not so large
[07:15:31] <toner> but they have a very thin nylon skin
[07:15:46] <toner> almost no structural support
[07:15:59] <toner> I guess it relies on the hot air pushing outwards to hold the shape
[07:16:05] <Valen> square cube law is your friend as you get bigger
[07:16:06] <toner> and the nylon has nice sheer strength

[08:17:19] <Valen> that reminds me
[08:17:33] <Valen> i have a spare laptop, my dad wants a DRO for his lathe
[08:17:39] <Valen> it has the encoders on it already
[08:17:44] <Valen> and the laptop has a parallel port
[08:17:55] <Valen> how much mucking about with HAL am i looking at here ;->
[08:18:20] <Loetmichel> why linuxCNC for DISPLAY?
[08:18:29] <Loetmichel> google yadro
[08:22:03] <cabbage> Hey guys
[08:22:18] <Valen> i was hoping not to add any more components
[08:22:34] <cabbage> ive just finished building a co2 laser and am thinking of running it on linuxcnc
[08:24:11] <Loetmichel> Valen: yadro is a software for old laptops to display digital calipers
[08:24:22] <Loetmichel> and can iirc cope with encoders also
[08:24:38] <Valen> but it needs some micro controller to talk to it
[08:24:47] <Loetmichel> and only needs an old 486 laptop or so, dos
[08:24:55] <Valen> the laptop is fine
[08:24:59] <Valen> its a pentium M 2ghz
[08:25:01] <Loetmichel> hmmm
[08:25:01] <Valen> no hdd though
[08:25:26] <Valen> and that yadro thing needs a $100 pcb
[08:25:29] <Loetmichel> it needs a controller for the calipers
[08:25:44] <Valen> it only talks serial port by the sound of things
[08:25:45] <Loetmichel> does it need one for encoders? dont remember
[08:25:52] <Loetmichel> ah, i seee
[08:25:58] <Valen> http://www.yadro.de/dro/interface.html
[08:26:03] <Loetmichel> seen that long time ago ;-)
[08:26:04] <Loetmichel> sorry
[08:26:08] <Valen> no worries
[08:26:17] <Valen> I just know EMC has the functions i need
[08:26:23] <Valen> and it talks parallel port

[09:05:46] <alex_joni> Valen: using only HAL you can easily do that
[09:06:02] <Valen> i figured that
[09:06:12] <Valen> I'll have to fire up emc on this thing and see what the latency is still
[09:06:21] <Valen> if its really bad it'll miss counts
[09:06:22] <alex_joni> right
[09:06:41] <alex_joni> what encoder resolution?
[09:06:48] <alex_joni> and what speeds are you looking at?
[09:07:07] <alex_joni> counting something like 20k pulses/second is somehow reliable
[09:07:10] <Valen> 5um and however fast he can spin the handle
[09:07:20] <alex_joni> much above that gets questionable

[09:43:06] <alex_joni> Valen: 5um is not really a value I can use
[09:43:25] <alex_joni> you either have linear scales , then 5um makes some sense
[09:43:37] <alex_joni> or you have encoders, then you get xx pulses/rotation
[09:43:55] <alex_joni> (obviously the 5um can get converted, if you know the screw tpi)
[09:46:15] <Valen> i have linear scales
[09:46:20] <Valen> glass slides
[09:46:47] <Valen> but as far as emc is concerned theres no difference
[09:47:02] <Valen> and most people only know about encoders ;->

[12:24:08] <jthornton> probably reading the 203v manual or asking Marris on the zone... been a long time
[12:24:36] <Tom_itx> k, just wondered since the manual says a 50% duty pulse
[12:25:27] <Tom_itx> it didn't seem to matter alot when i tested the old controller though
[12:25:39] <Tom_itx> i tried several different ones

[12:27:49] <Tom_itx> at least the psu didn't go up in smoke
[12:28:13] <jthornton> that's always a good thing
[12:29:29] <jthornton> I need to bite the bullet and convert the Anilam on the BP knee mill
[12:31:00] <jthornton> I've got all the wires traced out and documented so in theory I'm ready to make the swap
[12:34:22] <jymmm> jthorntonJust tell me the wires are not 'stamped'
[12:37:07] <jthornton> no I didn't step on them
[12:40:34] <jymmm> I was wiring up a dayton 220/440 5hp motor one time for 220 3ph. It had the wires 'hot stamped' with a number on each one. Except when I wired up #6, it really was #8 with part of the 'hot stamp' rubbed off. Stunk like crazy when we hit the power.
[12:43:37] <jymmm> jthornton: I just didn't want you to have the same #6 and #8 issue as I did.

[12:50:09] <jthornton> never heard of that wiring scheme
[12:50:48] <jymmm> Me neither, but since I just had blew up an expensive motor I did check that.
[12:55:17] <alex_joni> blown*
[12:55:47] <jymmm> alex_joni: your momma!
[12:56:02] <alex_joni> yo momma
[12:59:05] <jymmm> How can you tell if something has a high carbon content? Like a knife or bar stock?
[13:06:36] -!- FinboySlick [FinboySlick!~shark@] has joined #linuxcnc
[13:08:48] <syyl> know the spark test?
[13:09:00] <syyl> hold the piece against a bench grinder
[13:09:03] <syyl> and watch the sparks
[13:09:05] <jymmm> flint n steel
[13:09:26] <syyl> http://en.wikipedia.org/wiki/Spark_testing
[13:10:00] <syyl> if the sparks are burning like fireworks, you got a high carbon steel
[13:10:01] <syyl> :D
[13:10:12] <jymmm> Heh, I get sparks from everything when I use my angle grinder =) My goal is 50ft sparks, only up to 20ft so far
[13:10:35] <syyl> sparks != sparks
[13:10:36] <syyl> :P
[13:10:53] <jymmm> O_o
[13:10:54] <syyl> at least for the machinist..
[13:11:01] <jymmm> ah
[13:11:25] <jymmm> Well, I meant a none destructive method. Like at a flea market looking at knives
[13:11:34] <syyl> ah ok
[13:11:47] <syyl> those people dont like if you grind a piece of their stuff ;)
[13:12:18] <jymmm> and carrying around a grinder and 10,000 foot extension cord not too fun either
[13:12:28] <syyl> no cordless anglegrinder? :P
[13:12:32] <alex_joni> you can try bending it.. if it snaps, it's probably high carbon
[13:12:39] <alex_joni> s/it's/it was/
[13:12:47] <syyl> or try to scratch glass
[13:12:55] <jymmm> alex_joni: non-destructive =)
[13:13:12] <alex_joni> well, it's non-destructive in some cases :D
[13:13:21] <jymmm> syyl: wont a ss knife screw glass?
[13:13:26] <jymmm> scratch
[13:13:26] <syyl> "its ok, just a bit bent"
[13:13:55] <syyl> most high carbon steels can be hardened to scratch glass
[13:14:04] <syyl> but my leatherman wave is unable to do...
[13:14:20] <jymmm> you didnt try hard enough
[13:14:27] <syyl> i like my tools ;)
[13:14:40] <jymmm> it has a lifetime warranty
[13:14:47] <syyl> i know
[13:14:53] <jymmm> do you have the riginal or newer wave?
[13:14:54] <syyl> but i like it as it is :D
[13:14:57] <jymmm> original
[13:15:03] <syyl> the 2004(?) wave
[13:15:22] <jymmm> brown leather sheaf?
[13:15:29] <syyl> black it was
[13:15:36] <jymmm> leather?
[13:15:37] <syyl> now its brown
[13:15:39] <syyl> yeah
[13:15:45] <jymmm> mine too
[13:15:53] <jymmm> but brown
[13:16:09] <syyl> http://gtwr.de/leatherman.jpg
[13:16:33] <jymmm> I like it, but too many fucking flat blade screwdrivers and all are crap tips
[13:16:43] <syyl> got that &"§/!! maglite for free with the wave
[13:16:53] <jymmm> sorry to hear it
[13:17:13] <jymmm> Oh, yours is newer than mine
[13:17:20] <Loetmichel> jymmm: thats what the bit holder is for
[13:17:29] <syyl> i like it, its a good tool
[13:17:37] <syyl> not heavy duty, but ok
[13:17:43] <jymmm> Loetmichel: I dont have a bit holder
[13:17:57] <Loetmichel> mine: http://www.cyrom.org/palbum/main.php?g2_itemId=12165
[13:17:59] <jymmm> thats the newer wave
[13:18:23] <syyl> still waiting for the leatherman oht
[13:18:29] <Loetmichel> jymmm: got it ager killing my old one... they have no spare parts for it
[13:18:31] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12016
[13:18:51] <Loetmichel> so they returned me a new wave instead of my old one
[13:19:13] -!- mk0 has quit [Quit: LinuxCNC 2.5.0!]
[13:19:28] <Loetmichel> i like the lifelong free repair policy ;-)
[13:19:36] <jymmm> Yeah, that's what I have.
[13:20:09] <Loetmichel> hmm, i had a bitholder in the old set
[13:20:11] <Loetmichel> mometn
[13:20:20] <jymmm> I love the diamond file, too bad it's not removable so you could use it to sharpen the blade
[13:20:38] <syyl> for my taste it would be to rough to sharpen the blade
[13:20:44] <syyl> i prefer an arkansas stone
[13:20:57] <syyl> like it sharp as hell ;)
[13:21:00] <jymmm> If you have it on you
[13:21:37] <Valen> i have a leatherman squirt P4 on my keyring
[13:21:39] <syyl> i have one in my backpack
[13:21:56] <syyl> and one in the toolkit of the car
[13:22:14] <jymmm> I just picked up a Buck Knives diamond sharpener, one end is tapered so you can sharpen serrated blades
[13:22:28] <Loetmichel> jymmm: http://www.cyrom.org/palbum/main.php?g2_itemId=13224
[13:22:31] <jymmm> and of course has a lifetime warranty
[13:23:02] <syyl> ah, i know somebody that has that buck sharpener "pen"
[13:23:09] <syyl> it seems to work very well
[13:23:14] <Valen> http://www.leatherman.com/product/Squirt_P4 is mine
[13:23:29] <Valen> best christmass present ever ;->
[13:23:47] <syyl> the squirts are nice, yeah :D
[13:23:55] <syyl> pretty capable for their size
[13:23:59] <Valen> i like that its small enough to go onto my keyring
[13:24:07] <Valen> i use it all the time
[13:24:44] <Valen> also the nylon holster thing is just big enough that i can fit a super tiny 8Gb USB key in it
[13:24:47] <jymmm> syyl: http://www.buckknives.com/index.cfm?event=product.detail&productID=3033
[13:25:12] <jymmm> I wish they had a finer grit one as well
[13:25:12] <syyl> jep, thats the one
[13:27:39] * jymmm crank calls Loetmichel
[13:27:48] <jymmm> ;)
[13:27:50] <Loetmichel> hrhr
[13:28:34] <jymmm> Loetmichel: I can call anywhere on the planet for free, off planet is like $8/minute
[13:28:41] <syyl> i got a old style swiss tool
[13:28:46] <syyl> thats heavy duty ;)
[13:28:59] <syyl> but it weights a ton
[13:29:02] <jymmm> victronox?
[13:29:07] <syyl> yeah
[13:29:25] <syyl> used to carry it for a few years on daily basis
[13:29:29] <jymmm> I'm STILL trying to figure out why they always has a corkscrew =)
[13:29:40] <syyl> the swisstool has none :(
[13:29:45] <syyl> but then i switched to the wave
[13:29:46] <jymmm> Bunch of drunk soldiers?
[13:29:49] <Valen> so you can get drunk on good wine after using it lol
[13:29:59] <Loetmichel> jymmm: the engraving has proven its woth two times 'til now... i tend to be a bit forgetfil ;-)
[13:30:02] <syyl> as it is smaller and easier to handle (i.e. onehanded blades)
[13:30:21] <jymmm> Loetmichel: Really? that's cool =)
[13:30:57] <jymmm> You can get a #4 or #6 split ring at the fishing store fror lanyard use
[13:31:54] <syyl> uh
[13:31:55] <syyl> http://www.leatherman.com/product/Sidekick
[13:32:00] <syyl> never saw that one
[13:32:05] <syyl> with spring action pliers
[13:32:58] <Loetmichel> jymmm: yeah, it seems the species "honest finder" isnt extinct here ;-)
[13:33:08] <jymmm> =)
[13:33:18] <jymmm> Ewwwwwwww file and saw look like crap
[13:34:13] <Loetmichel> hmm, the wave saw is useable
[13:34:17] <Loetmichel> and the file too
[13:34:24] <jymmm> yep
[13:34:32] <Valen> the squirt pliers are spring loaded
[13:34:36] <Valen> rather neatly too
[13:34:41] <jymmm> and the serrated blade on the wingman is useless
[13:34:50] <Valen> they have little torsion style springs in the handle
[13:34:58] <syyl> i like the way the pliers on the squirt unfold, Valen :D
[13:35:07] <Valen> syyl: i love the noise they make lol
[13:35:11] <Loetmichel> the saw has freed me out of a decoration made of 21mm thick "pressed wood chips" plates
[13:35:15] <Valen> I have often thaught about making a set of pliers
[13:35:19] <Loetmichel> waht is it called in english?
[13:35:21] <Valen> but "the ultimate" pliers
[13:35:30] <Valen> MDF is the one thats like dust
[13:35:37] <syyl> ultimate pliers?
[13:35:44] <syyl> go to knipex :)
[13:35:44] <Valen> chipboard is the one thats a few mm in size (the chips)
[13:35:45] <Loetmichel> no,. the bigger chips
[13:35:50] <syyl> chipboard
[13:35:58] <Loetmichel> ah
[13:35:58] <Valen> nah, better than them
[13:36:07] <syyl> better than knipex?
[13:36:11] <Valen> angular contact bearing (or a bushing)
[13:36:11] <Loetmichel> thge ones with nails and stones in it ;-)
[13:36:12] <jymmm> channellocks?
[13:36:16] <jymmm> vise grips?
[13:36:20] <Valen> not a pin that can wear
[13:36:27] <Valen> user servicable
[13:36:33] <Valen> replacable carbide jaws
[13:36:42] <syyl> i have knipex sidecutters from my father, +20years
[13:36:45] <Valen> stainless handles
[13:36:48] <jymmm> bolt cutters
[13:36:58] <syyl> they still work :D
[13:37:08] <Valen> I bet they aren't as good as the day they were made though
[13:37:18] <syyl> of course not
[13:37:25] <syyl> but they had their workout :D
[13:37:35] <syyl> a lot of heavy wire, piano wire
[13:38:08] <Valen> see in mine you could fix the slop by just tightening up the bearing, and replace the carbide inserts in the jaws
[13:38:14] <Valen> presto its as good as new
[13:38:34] <jymmm> I sharpened my T&B cutters with the Buck diamond stick, cuts like new now. No need to get it replaced under warranty
[13:38:38] <Loetmichel> Valen: if the brand is "knipex" the ARE as good today
[13:38:54] <Valen> well Loetmichel syyl just said they werent
[13:39:07] <Valen> and he has a pair he has been using for 20 years
[13:39:29] <Loetmichel> Valen: last one i bought si now about 5 jears old, and still the same quality as the ones from 30 years ago
[13:39:35] <Valen> the point i am making isn't that they are bad, its that you can't service them
[13:39:52] <Valen> yes, but if you have been using them for 30 years they will get worn
[13:40:10] <Loetmichel> ... but now ith 1000V isolated grips ;-)
[13:40:30] <jymmm> Loetmichel: wuss
[13:40:55] <Valen> you don't like the idea of the pliers I suggest?
[13:41:00] <Loetmichel> i have one sidecutter which is now a isolation stripper ;-)
[13:41:26] <Loetmichel> bought new... few days later i got the wrong cable to cut...
[13:41:29] <Loetmichel> *BAM*
[13:42:04] <jymmm> hole in jaws?
[13:42:08] <Loetmichel> now it has a nice hole for awg16 stripping in the cutting knifes ;-)
[13:42:40] <jymmm> yeah, been there, done that.
[13:42:51] <Loetmichel> but otherwise still functional
[13:43:08] <jymmm> I unpluged it, but someone plugged it back in. DOH
[13:43:15] <Loetmichel> even after rough mishandling and cutting 6mm 8.8 threaded bolts
[13:43:57] <Loetmichel> better than a friend of mine
[13:44:23] <Loetmichel> he was told to saw off the main power cable of a building "there at that concrete pillar"
[13:44:27] -!- joe9 has quit [Quit: leaving]
[13:44:30] <Loetmichel> ... he did...
[13:45:05] <Loetmichel> what he didnt knew: the 5*90mm^2 copper on the OTHER side of the pillar was still under power
[13:45:17] <Loetmichel> ... he got the wrong one
[13:45:23] <Loetmichel> THAT was a bang
[13:45:40] <Loetmichel> ~10cm of the saw blade simply disintegrated
[13:46:12] <jymmm> just a lil spark, no biggy
[13:46:13] <Loetmichel> he had some molten steel in his clothes and face and couldnt see anything for a while
[13:46:38] <Loetmichel> otherwise he was fine
[13:46:55] <jymmm> he should have checked if it was live or not
[13:47:16] <Loetmichel> my fault
[13:47:33] <Loetmichel> i shouldnt have told a lathe guy to do electricans work ;-)
[13:47:51] <jymmm> ah
[13:50:40] <Loetmichel> i should have imagined that he would cut the cable running neatly fom the ground to the ceiling instad of the one with open ends looking in his face beside it

[17:22:02] <ScribbleJ> I have an integrated ER11 spindle, can I just assume any ER11 collets are goingto fit right, I mean, ... that's why it's a dumb question. It's a standard, so they all work interchangably,... right?
[17:23:13] <IchGuckLive> yes
[17:25:33] <ScribbleJ> Thanks. IT's not easy being stupid.

[17:28:03] <Tom_itx> mmm
[17:30:33] <Tom_itx> alot of software just to build a bit file
[17:32:31] <pcw_home> I think the whole webpack suite just barely fits on a DVD now (compressed)
[17:32:50] <Tom_itx> i couldn't find the.xml file
[17:33:22] <pcw_home> you trying to run pncconf?
[17:33:51] <Tom_itx> no
[17:34:15] <Tom_itx> what does that do?
[17:34:21] <Tom_itx> i don't think i've ever run it
[17:38:26] <pcw_home> its a GUI configuration program for Mesa cards (and what the xml file is needed for)
[17:38:37] <Tom_itx> oh
[17:38:47] <Tom_itx> so i really don't need the xml
[17:38:59] <pcw_home> no
[17:40:05] <Tom_itx> oh well, it's good practice
[17:45:13] <pcw_home> I think the LinuxCNC build script for the bitfiles makes the XML files but I dont generate them

[18:44:08] <frallzor> how to set the WCS btw?
[18:44:55] <andypugh> That "secure set" reminds me of this: http://www.diyfaq.org.uk/humour.html#foam
[18:45:14] <JT-Shop> from the SW menu insert/reference/coordinate system and put that where 0,0,0 is and make sure XYZ point the right way
[18:45:38] <JT-Shop> next, on the hsm tab right click on job and select edit
[18:46:21] <frallzor> ah you mean that, that I can do allready
[18:46:32] <frallzor> (just not into all terms) =)
[18:47:01] <JT-Shop> ok
[18:48:50] <JT-Shop> crappy boring bar set uses a T8 screw and 1/4" IC inserts and you can't find any replacements as 1/4" IC only has a 0.089" through hole!
[18:48:57] <frallzor> ill stick with either the mach2 PP or the modified EMC and keep remembering it changes offsets and doesnt home =P

[18:49:34] -!- Thetawaves [Thetawaves!~Thetawave@] has joined #linuxcnc
[18:49:51] <JT-Shop> how does it change offsets again?
[18:50:00] <frallzor> I mean return to home when done
[18:50:05] <frallzor> the EMC-one doesnt
[18:50:18] <frallzor> just retracts the spindle and thats it
[18:50:19] <JT-Shop> a G28 move?
[18:50:30] <frallzor> tried adding one actually
[18:50:34] <frallzor> didnt happen anything
[18:50:46] <frallzor> for some reason
[18:51:50] <JT-Shop> does it generate a G28 move at the end?
[18:52:04] <frallzor> pretty sure it didnt
[18:52:14] <frallzor> I recall trying to add one with no luck
[18:53:47] <JT-Shop> look for something like this in the PP http://pastebin.com/VHT7r2kx
[18:54:18] <JT-Shop> second question did you set up the G28 location you wish the machine to go to?
[18:55:31] <frallzor> yup
[18:55:49] <frallzor> XY 0
[18:56:05] <frallzor> the Z shouldnt be concerned when allready retracted?
[18:56:44] <frallzor> found that part in the PP
[18:57:06] <JT-Shop> look in your function onClose() for writeBlock(gFormat.format(28)
[18:58:23] <frallzor> si
[18:59:11] <frallzor> oh add home positions in the code?
[18:59:15] <frallzor> *in the PP
[18:59:24] <JT-Shop> add a g28
[18:59:55] <frallzor> now you lost me, according to my basic knowledge is seems its allready there?
[19:00:44] <JT-Shop> your using mach2mill.cps?
[19:01:00] <frallzor> im in the emc pp you sent me
[19:01:23] <frallzor> but when i use mach2mill it functions like expected yes =)
[19:01:36] <frallzor> goes to 0.0 etc etc when done
[19:01:46] <JT-Shop> linuxcnc-mill.cps?

[19:03:43] <frallzor> ah so simple as that?
[19:04:08] <JT-Shop> yea, I turned it off in case you had not set up your G28 position
[19:04:59] <frallzor> I assume thats what I do everytime
[19:07:20] <frallzor> it shall return to where I home it now I assume?
[19:07:37] <frallzor> yx 0 and the retracted height of Z?
[19:07:55] <JT-Shop> it will return to where you have set G28 which has nothing to do with homing
[19:08:20] <frallzor> all I do is home
[19:08:26] <JT-Shop> http://gnipsel.com/linuxcnc/tutorial/mill03.html
[19:08:30] <frallzor> and then it allways returns there
[19:09:15] <JT-Shop> you only home when you first power up right?
[19:09:18] <frallzor> yup
[19:09:30] <frallzor> and the machine allways "returns" home when done
[19:09:45] <frallzor> except with the emc PP
[19:09:48] <JT-Shop> not unless you tell it to somehow
[19:09:59] <frallzor> I assume its the PP then
[19:10:04] <JT-Shop> ok then G28 is set to 0,0,0
[19:10:17] <frallzor> figured that
[19:10:17] <JT-Shop> read that short link
[19:11:03] <frallzor> ah I see
[19:11:39] <frallzor> I assume I set G28 somehow when making the operations in HSM?
[19:12:02] <JT-Shop> nope you do that in the MDI window with G28.1
[19:12:26] <frallzor> nothing I have ever done =)
[19:12:43] <frallzor> there isnt a default set?
[19:12:45] <JT-Shop> try it you will like it :-)
[19:13:04] <JT-Shop> no such thing as default settings in LinuxCNC
[19:13:11] <frallzor> since it seems to rely on things I have never done :P
[19:13:22] <JT-Shop> lucky guy
[19:13:46] <JT-Shop> that's why I wrote the G code tutorial
[19:15:49] <frallzor> odd that its allways worked like this for me =)
[19:16:04] <frallzor> it allways does what it should, retracts, and goes back to xy0
[19:16:59] <JT-Shop> what does the G28 line look like at the end of your g code?

[19:25:28] <frallzor> stupid gfx-driver =(
[19:26:56] <jymmm> Is there a simplistic way to automate the dispensing of a pre-determined amount of hot liquid?
[19:27:32] <JT-Shop> yep
[19:27:33] <cradek> I take a leak about the same time every morning
[19:27:48] <JT-Shop> metering pump
[19:27:53] <jymmm> cradek: the amount can vary =)
[19:27:59] <jymmm> JT-Shop: sounds expensive
[19:28:10] <jymmm> JT-Shop: is there a ghetto version?
[19:28:23] <JT-Shop> depends on the volume and how accurate you need it
[19:28:43] <frallzor> JT-Shop you look like a handy dandy man
[19:28:53] <frallzor> you into wood working?
[19:29:06] <jymmm> maybe 0.25oz +/- 10%
[19:29:08] <JT-Shop> we use two air cylinders and two check valves to put hot oil into lawnmower engines on the assembly line
[19:29:57] <JT-Shop> you should be able to do that with air cylinders provided the liquid is not harmful to the seals
[19:30:11] <jymmm> JT-Shop: how did you set the qty?
[19:30:24] <jymmm> no damage to seals
[19:30:27] <JT-Shop> adjust the stroke with physical stops
[19:30:57] <JT-Shop> couple air cylinders together so one cylinder strokes the second one
[19:31:08] <jymmm> JT-Shop: no way to replace the physical stops with a ladder entry?
[19:31:13] <JT-Shop> back side of pump cyl is vented and front side is the pump
[19:31:50] <JT-Shop> sure change driving cyl to a servo driven linear actuator
[19:32:04] <jymmm> oh, heh
[19:32:29] <JT-Shop> you talking tweaking the amount or double/half changes
[19:34:02] <jymmm> different capacities and just have one CL file per. I also suspect the volume is going to change summer/winter and want to consistantly be able to adjust for that.
[19:35:04] <JT-Shop> so two change overs per year?
[19:35:16] <jymmm> minimum
[19:35:32] <jymmm> I wonder how much a surplus IV pump goes for
[19:35:51] <JT-Shop> just make the driving cyl a double rod and have an adjusting nut and jam nut on the free one then
[19:36:05] <JT-Shop> too slow
[19:36:38] <jymmm> Do any of the measuring pumps have heaters too?
[19:37:08] <JT-Shop> we put the heater into the liquid tank, the more mass the more stable the temperature
[19:37:24] <JT-Shop> what material are you heating?
[19:37:53] <jymmm> wax
[19:39:11] <JT-Shop> low watt density heaters for that I assume
[19:39:31] <JT-Shop> and perhaps a band heater on the cylinder
[19:40:02] <jymmm> Yeah, it's just the plumbing/piping that I think would be an issue
[19:43:02] <JT-Shop> mount the metering cyl inside the tank
[19:44:30] <jymmm> JT-Shop: do you have a link to one of these cyl by chance?
[19:45:16] <JT-Shop> bimba would be the cheapest
[19:45:32] <jdhNC> nothing like having a cheap bimbo

[19:52:12] <JT-Shop> aye
[19:52:35] <JT-Shop> + two check valves and you have a pump
[19:52:49] <JT-Shop> a positive displacement pump actually
[19:52:51] <jymmm> one cyl and two check valves?
[19:53:09] <JT-Shop> that makes the pump part yes
[19:53:23] <JT-Shop> you still need a second cyl to stroke the pump
[19:53:23] <jymmm> and what to drive "the pump"?
[19:53:28] <jymmm> k
[19:54:07] <jymmm> you think a steper motor and a 2-4" wheel attached to it could drive the pump?
[19:55:14] <JT-Shop> you might make a linear actuator from a stepper motor and a acme screw, but first you need to know how much force is needed to stroke the pump
[19:55:30] <archivist> the obvious questions arise, viscosity, stepper size, smallest holes the liquid is forced through, and you want an answer
[19:57:08] <jymmm> JT-Shop: and no issue installing the cyl in a hot tank huh?
[19:57:22] <cradek> air works great for stuff like this
[19:57:39] <cradek> you can get speed and force from air cyls so easily
[19:58:05] <jymmm> cradek: can you control the stroke with air?
[19:58:57] <cradek> no, you'd adjust the stroke with mechanical stops
[19:58:59] <archivist> you missed the explanation of stroke length control

[20:11:44] <Aero-Tec> no twisted pair
[20:12:16] <jymmm> Aero-Tec: then I'd suggest you get some shielded and/or twist pair and try it as a test.
[20:12:31] <Aero-Tec> are you asking about sig connection or wires to the motor, nether are twisted
[20:12:53] <Aero-Tec> so your talking the sig lines
[20:13:19] <jymmm> twisted pair helps reduce electrical cross-talk noise.
[20:14:38] <Aero-Tec> so sig line twisted around the ground line?
[20:15:01] <jymmm> well, usually the other way around, but yes.
[20:15:19] <Aero-Tec> we are not talking the motor wires right?
[20:15:45] <jymmm> Yes, cable between drive and motor
[20:16:03] <jymmm> especially if it's long

[20:26:32] <Aero-Tec> funny thing is it come and goes with out my doing any thing
[20:26:59] <Aero-Tec> would have to go to the big city to find that
[20:27:09] <Aero-Tec> the other stuff was local
[20:27:13] <jymmm> Aero-Tec: you can probably hit home depot and get a 4cond, shielded pair at to test with.
[20:27:16] <Aero-Tec> but I may just do that

[20:29:01] <Aero-Tec> it can run very well and then start messing up
[20:29:37] <Aero-Tec> some time the motor will not move, some times it move well but you can just hear it is not smooth
[20:29:39] <archivist> your descriptions of faults do not help us to help you
[20:29:46] <Aero-Tec> and other time it run great
[20:30:26] <Aero-Tec> also some time it will trigger error right away, some times in mid move, and yet other time it will not trip at all
[20:30:56] <archivist> Aero-Tec, read this http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Drive_Timing
[20:30:57] <Aero-Tec> even when the motor in not moving but the dro is going it will not trip the error on the geckos
[20:31:36] <Aero-Tec> yet some times it trips so fast it is all most instant
[20:32:49] <Aero-Tec> oh and one other thing
[20:33:26] <Aero-Tec> some time one drive, ether x or z, some times both

[21:01:25] <A0Sheds> anyone converted their oxy/acetylene torches to oxy/propane?
[21:02:55] <roycroft> i haven
[21:02:57] <roycroft> 't
[21:02:58] <cradek> jewelers sometimes use oxy/natural gas
[21:03:13] <roycroft> jewlers usually us acetylene/air
[21:03:15] <roycroft> use
[21:03:35] <roycroft> my smith jewler's torch (which is what most jewlers have) is acetylene/air
[21:03:36] <cradek> are you sure? iirc acetylene puts that black ash in the castings
[21:03:58] <A0Sheds> they bumped the price of acetylene up around here
[21:04:04] <roycroft> i don't see the purpose of converting an acetylene torch to propane
[21:04:08] <roycroft> the acetylene crisis is over
[21:04:12] <cradek> I think the one I worked for used something different for platinum - maybe it was propane?
[21:04:14] <A0Sheds> I use it just for cutting
[21:04:34] <cradek> I bet many people have a huge propane tank nearby for heating
[21:04:41] <micges> A0Sheds: hand or machine torch?
[21:04:45] <roycroft> for day-to-day solderling/annealing work the smith acetylene/air torch is the standard
[21:04:47] <cradek> seems convenient then
[21:04:52] <A0Sheds> micges, hand
[21:04:59] <roycroft> i can see using different gasses for other purposes
[21:05:04] <roycroft> so we may both be right :)
[21:05:08] * cradek shrugs
[21:05:15] <cradek> it's been years and my memory is always a bit fuzzy anyway
[21:05:24] <roycroft> and i've never worked with platinum
[21:05:31] * roycroft 's blood isn't that rich
[21:06:01] <roycroft> i've hardly ever worked with gold, myself
[21:06:09] <roycroft> mostly silver and red metals
[21:06:51] <andypugh> Acetylene is becoming hard to get hold of now. Something to do with being rather dangerous.
[21:07:07] <archivist> we just used a propane blunderbuss for clock stuff at the last job
[21:07:20] <A0Sheds> to go to natural gas/oxy for cutting I'd need to bump the 1 PSI up to ~45 or so
[21:07:38] <andypugh> My sister's welding torch is oxy-hydrogen.
[21:07:51] <roycroft> acetylene is in good supply again
[21:07:56] <A0Sheds> andypugh, the story around here was a large plant fire that caused a shortage
[21:08:15] <roycroft> a big acetylene production plant in washington stage blew up last year, and the price went crazy for a while
[21:08:19] <roycroft> but it's come back down again
[21:08:35] <roycroft> at least in eugene
[21:08:37] <A0Sheds> I guess they haven't heard of the price drop around here :)
[21:09:01] <roycroft> plasma is cheaper than any gas :)
[21:09:04] <A0Sheds> 30% bump
[21:09:10] <andypugh> We have been prevented from storing acetylene in the workshop because it is inconvenient in case of fire (100yd exclusion zone for a day or two)
[21:09:38] <roycroft> since you make your own plasma
[21:09:51] <roycroft> from readily-available materials
[21:10:02] <andypugh> When that radius includes the Royal Albert Hall and a major University, that is a problem.
[21:10:15] <archivist> firemen are a little wimpish over acetylene bottles over here
[21:11:08] <A0Sheds> the plasma cutter doesn't do to well cutting off bolts on rusty suspensions
[21:11:15] <andypugh> I don't know what the alternative is for bronze-welding though.
[21:12:47] <A0Sheds> andypugh, how well to the 1-3L diesels in the EU do running on biodiesel?
[21:13:07] <andypugh> The common-rail ones don't like it at all.
[21:13:55] <A0Sheds> andypugh, I've been considering importing used but working diesels from the EU for retrofits into older cars here
[21:14:41] <andypugh> If you stick to rotary pump ones, no problem. Actually, "proper" biodiesel is fine too. The problem is trying to use refined chip-fat.
[21:15:22] <A0Sheds> andypugh, what is the problem with refined was oils/fats? not enough filtering or?
[21:16:11] <andypugh> They meter by time, not volume. So unless the viscosity (and temperature/viscosity relationship) are the same as pump diesel then the fuelling is all wrong.
[21:16:28] <A0Sheds> ok, interesting
[21:16:54] <A0Sheds> so if I match the viscosity over temp close enough it should be good
[21:17:04] <andypugh> In theory.
[21:17:06] <A0Sheds> play with additives. wax etc
[21:17:38] <andypugh> But your pump fuel is practically free anyway.

[21:17:57] <A0Sheds> andypugh, how about reprogramming the cpu's for different curves?
[21:18:54] <andypugh> That would work, if you could get into the ECU, and if you had the equipment to work out which numbers to put in.
[21:19:19] <andypugh> (and find the right map, we have 40,000 calibration labels)
[21:19:40] <A0Sheds> cars would need new ECU's anyway for a retrofit from gas to diesel
[21:20:24] <andypugh> Yes, and that would be a problem too. You can't just take the one from the original engine, as they talk to so many other vehicle systems.
[21:20:50] <andypugh> We can't even swap modules between the same engine in different cars.
[21:20:59] <A0Sheds> but for pre-OBD cars
[21:21:26] <andypugh> (ie the Mondeo ECU won't work at all in a Focus, even with the same DW10C engne)
[21:21:45] <andypugh> If you stick to rotary-pump engines you should be fine,
[21:21:55] <andypugh> But those are all getting a bit old now.
[21:22:08] <archivist> mine still runs :)
[21:22:15] <A0Sheds> there's a market for them here
[21:22:30] <andypugh> There's no market for new ones, it appears.
[21:22:35] <A0Sheds> it's really hard to find small diesels for a low price
[21:22:51] <andypugh> That's because they really struggle with the US emissions regs.
[21:22:52] <archivist> 184k miles and I had to order a wheel bearing today!
[21:23:05] <A0Sheds> an old VW diesel engine might sell for $>1K

[21:26:44] <jymmm> JT-Shop: Wow, those Bimbas are cheap, even at high temp ratings, etc. TYVM
[21:27:20] <archivist> A0Sheds, the other name we used to use was Dagenham Dustbin
[21:27:56] <andypugh> Wasn't it made in Genk?
[21:28:04] <A0Sheds> they purposely left the emissions levels low to keep diesels off the streets here, is there a problem with sulfur in the air in the EU?
[21:28:30] <andypugh> No. There was, but it seems OK now. The trees grow in Norway again.
[21:28:48] <archivist> andypugh, I dont think that term has been used much since the 1970's for fords
[21:29:37] <A0Sheds> they decided it was best for the oil co's here if 50-60mpg diesels were kept of the US streets
[21:29:42] <andypugh> We are _really_ struggling with the next set of NOx limits, it is going to cost a great deal of fuel economy. Considering I don't think there has been a photochemical smog for decades, I think perhaps that particular limit might be low enough now.
[21:29:42] <archivist> when we had rust buckets like the Anglia
[21:30:28] <andypugh> We had an Anglia when I was a kid. I used to think that all cars needed shoving to the adjacent hill to start them.
[21:30:57] <A0Sheds> was there an EU version of the Pinto?

[22:09:10] <atom1> it looks like it maps to hostmot2 maxaccel

[22:15:43] <andypugh> Tom_itx: One is a machine limit, the other is err, something else.
[22:15:52] <Tom_itx> hah
[22:16:19] <andypugh> It used to be that you could leave the stepgen one at zero, but PCW found a reason not to.
[22:16:44] <Tom_itx> well you'd think it wouldn't be set higher than the machine limit one
[22:16:59] <andypugh> No, I think it needs to be 10% higher.
[22:17:11] <JT-Shop> yea there was some reason to set it some percent higher should be a note
[22:17:41] <Tom_itx> ok well mine doesn't have that parameter
[22:17:47] <Tom_itx> guess it will soon
[22:18:06] <JT-Shop> you can add custom items to the ini file and use them in your hal files
[22:18:15] <andypugh> Well, if your HAL doesn't use it, there is no point putting it in the iNI
[22:18:36] <Tom_itx> it's tied into the hostmot2 driver though isn't it?
[22:18:56] <andypugh> Only if it appears in the HAL
[22:19:13] <Tom_itx> i'd just like to know what the difference is

[22:21:28] <andypugh> maxaccel is a parameter of the Hostmot2 stepgen, unless there is a setp for it in the HAL file then it doesn't get set. The HAL drivers do not read the INI file.
[22:22:42] <Tom_itx> yeah i figured that
[22:22:43] <JT-Shop> no, but if you used it like setp hm2_5i25.0.stepgen.00.maxaccel [AXIS_0]STEPGEN_MAX_ACC
