[02:01:43] <Deejay> moin
[07:03:47] <PetefromTn> wtf I am so over this cold now.. ready for some spring weather!!
[07:12:14] <jthornton> me too
[07:12:57] <Tom_itx> 22 F
[07:13:37] <jthornton> Tom_itx, I got the save ops done
[07:15:29] <PetefromTn> LOL my van said 22 degrees on the way to taking my kids to school this morning.
[07:16:26] <Tom_itx> does it save everything?
[07:16:45] <Tom_itx> or select bits
[07:17:45] <jthornton> just what you select
[07:18:25] <jthornton> stupid thunderbird keeps adding a v onto my copy and paste
[07:26:07] <jthornton> got that crap turned off finally
[07:32:35] <Tom_itx> all i see posted is 1.6.08 still
[07:32:49] <jthornton> aye
[07:34:01] <jthornton> no use to save if you can't restore
[07:34:17] <Tom_itx> :D
[07:49:57] <Zaaarin> Hi guys I got some massive gears, but the scrapyard didn't have any pinions, they are MOD 3.0, any ideas where I can get some metal pinions from? I'm hoping to tapthread some pinion gears onto some NEMA 34's Here's a photo of these big metal gears I got: http://i.imgur.com/3BigwOv.jpg
[07:57:00] <MattyMatt> http://www.beltingonline.com/gears-racks-366/
[07:57:20] <MattyMatt> there's a place in poland that's good & cheap
[07:57:32] <Zaaarin> do either of them ship to Cyprus?
[07:58:09] <MattyMatt> ah beltingonline do, but expensively
[07:58:36] <MattyMatt> can't you print mod 3.0?
[07:58:43] <MattyMatt> that's massive
[07:59:07] <MattyMatt> nearly 10mm pitch teeth?
[07:59:45] <Zaaarin> I got a 3d printed one, but it ain't gonna handle the load for shite
[08:00:04] <Zaaarin> Hence why I know the gears I picked up are mod 3 for defos, meshed nicley with the ones Jezmy did for me ages ago
[08:00:56] <MattyMatt> http://www.beltingonline.com/gears-racks-366/spur-gears-367/metric-0-5-to-8-mod-375/3-0-mod-spur-gear-522/steel-391/ these are your babies then
[08:01:30] <MattyMatt> I got my lathe for the cost of about 10 of them :)
[08:02:14] <MattyMatt> fitting a lathe up for cutting gears would probably cost about 20 gears worth tho
[08:05:06] <Zaaarin> Better off with a water laser cutter
[08:06:06] <MattyMatt> you need to be, to get one :)
[08:06:15] <MattyMatt> especially if you gotta pay for water
[08:06:40] <Zaaarin> lol
[08:06:47] <Zaaarin> it's no joke, water is too expensive here
[08:07:23] <MattyMatt> geothermal desalination is the answer
[08:08:48] <MattyMatt> seawater goes down a hole, and comes up the neasert volcano as steam, with the sodium & chlorine piped up as a byproduct
[08:09:09] <jthornton> ok Tom_itx
[08:09:16] <jthornton> you can get 1.7.00 now
[08:09:23] <Zaaarin> If you understood the geology of Cyprus, you would know a) the gypsum ground is very unstable and hard to bore through without support, b) the water table is relatively high (although going down) and posses a problem for accessing geothermal, c)the cost
[08:09:30] <archivist> I just made a set of gears for a customer in Cyprus !
[08:09:37] <Zaaarin> Have you?
[08:09:42] <Zaaarin> How big?
[08:09:56] <archivist> how small you should ask
[08:10:06] <archivist> .5 mod
[08:10:32] <Zaaarin> :o I got mod 1 and those teeth are tiny
[08:10:43] <Zaaarin> 0.5 mod? Clockwork mouse teeth
[08:10:47] <Zaaarin> Model racing car
[08:11:24] <archivist> dancing frogs model
[08:11:27] <archivist> http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_01_19_Cyprus_gears/IMG_1735.JPG
[08:13:01] <archivist> google hpc gears for standard mod 3
[08:42:16] <Loetmichel> zaar: whrere is the problem?
[08:42:44] <Loetmichel> oh, gone already
[09:19:28] <JT-Shop> $288 delivered for two bottom track roller assemblies and a reversing lever
[09:19:44] <pcw_home> ???
[09:24:55] <JT-Shop> for my JD350 crawler... I thought the prices would be higher when I went looking for some used parts
[09:26:37] <pcw_home> Is it common enough that parts are easy to find?
[09:27:28] <JT-Shop> seems to be
[09:27:51] <JT-Shop> heck you can still get some new parts from John Deere
[09:34:58] <JT-Shop> ok
[09:35:44] <pcw_home> or measure DC motor supply voltage if you have the system
[09:36:05] <pcw_home> that and weight/size will get you pretty close
[09:36:12] <JT-Shop> yes, they have the whole system
[09:36:18] <JT-Shop> ok
[09:41:48] <pcw_home> I bet you could make a pretty good KW estimate based on motor weight and max RPM
[09:49:00] * JT-Shop bets Peter could make a pretty good estimate
[11:11:58] <Zaaarin> Hi does anybody know if there are any dangers when welding onto used gears coated in transmission fluid?
[11:15:33] <archivist> I usually treat gears with care not welding
[11:20:23] <Zaaarin> bolt them to something else that's welded?
[11:20:49] <archivist> what are you making
[11:22:17] <Zaaarin> I got some cogs today from the JCB scrap heap: http://i.imgur.com/GXNMs6w.jpg
[11:22:34] <Zaaarin> You see them 4 inch and 3 inch pipe segments in the topright corner?
[11:23:07] <Zaaarin> Idea is a central shaft that allows steam to permeate through the middle, the segments rotate without releasing much gas by way of the "labyrinth seal" concept
[11:23:22] <Zaaarin> Slow high torque rotation
[11:25:06] <Zaaarin> basically if I weld that 4 inch pipe into the middle of that flywheel, a) will the gear warp, b) will the residual transmission fluid on the gear's emmissions kill me? c) will it hold?
[11:25:22] <Zaaarin> I'm thinking of welding it with 6013
[11:25:47] <archivist> gears often are used in hydraulic motors low speed high torque, steam in high speed expansion type prime movers
[11:25:47] <Zaaarin> I don't even know if this is mild steel or some super hard alloy
[11:26:15] <Zaaarin> This is just to rotate a dish, the steam goes through the middle, the steam doesn't steer this at all
[11:28:00] <archivist> ring seal methinks, if there is any pressure behind the steam
[11:29:48] <archivist> will the gear warp, yes a bit where bit is unknown as we dont know your welding and if you are balancing the strain
[11:30:42] <Zaaarin> I was thinking of welding plates with 3 inch and 4 inch holes cut into each of them onto the 3 inch and 4 inch pipe segments so when it rotates there's minimal loss, maybe lathe the holes in the plates a bit so there's a bit of give between pipes
[11:30:51] <Zaaarin> What if I tac it in like 8 places around the pipe?
[11:32:06] <Zaaarin> The 3 inch pipe is the central drive shaft, the gear is connected to the pipe, the pinion on the motor turns the whole shaft
[11:32:39] <Zaaarin> I'm using 6013 2.5mm stick welding
[11:32:49] <archivist> what steam pressure are you dreaming of
[11:33:40] <Zaaarin> depends what a 4m parabolic dish coated in 10,000 little mirrors at this ceramic coated boiler concentrated from the sun will do, I'm guessing quite a few bar
[11:33:55] <Zaaarin> truth is I don't know, hence the project
[11:35:48] <archivist> I think you may be losing as much steam as you generate if you done rethink your sealing
[11:37:02] <Loetmichel> Zaaarin: depends on how big the boiler is
[11:37:53] <Loetmichel> 4m dish will generate about 12kW heat on a sunny day in the focal pint
[11:37:55] <Loetmichel> point
[11:38:04] <Jymmm> Make a molten salt solar stile instead =)
[11:39:10] <archivist> and steam boilers make good bombs
[11:39:44] <Jymmm> hot water heaters make good rockets too
[11:40:30] <Loetmichel> that accounts to evaporating at LEAST 60 milliliters water a SECOND
[11:40:44] <Loetmichel> and that is not a small amount of steam!
[11:40:50] <archivist> that scrap would not be allowed in the UK pressure vessel regulations
[11:42:35] <Jymmm> Water heater rocket http://www.youtube.com/watch?v=9bU-I2ZiML0
[11:44:34] <Loetmichel> Jymmm: you forgot to mentoun the two stories of "house" it penetrates before being a rocket ;-)
[11:45:04] <Jymmm> Loetmichel: That's just iicing on the cake
[11:48:04] <davef> Anyone know if this box will run linuxcnc OK? HP DC5700 small form factor computer.
[11:48:14] <davef> Specs:
[11:48:21] <davef> http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?sp4ts.oid=3249646&spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c00809043-33%257CdocLocale%253Den%257CcalledBy%253DSearch_Result&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken
[11:48:50] <Loetmichel> davef: should work
[11:49:21] <davef> Has on-board nVidia graphics -- ?
[11:49:23] <Loetmichel> but unless one of the inhabitants here HAS one you cant be sure because of issues with SMI tasks and stuff
[11:49:31] <archivist> if it passes the latency test with sensible numbers
[11:50:15] <Loetmichel> davef: i use a fuSi PC for my CNC
[11:50:16] <davef> Right. It's to be a replacement for my box with fried MB.
[11:50:23] <Loetmichel> that has a sempron3000 in it
[11:50:27] <Loetmichel> and it works
[11:50:35] <Loetmichel> the cpu isnt the problem
[11:50:51] <davef> Loetmichel: Sorry all greek to me. :)
[11:51:01] <Loetmichel> some of these boxes have power saving interrupts that will make your day miserable
[11:51:14] <davef> Hmmm...
[11:51:26] <Loetmichel> davef: FuSi= Fujitsu siemens
[11:51:36] <archivist> and nvdida steal your cycles also giving bad latency
[11:51:41] <davef> I just bought three of them used, have not picked them up yet...
[11:52:12] <Loetmichel> davef: so start the linuxCNC life CD in one and do a latency test
[11:52:20] <archivist> plug in another video adapter if the latency is bad
[11:52:20] <davef> I can disable the MB graphics and use a card though right?
[11:52:28] <archivist> yes
[11:52:28] <Loetmichel> the lifeCD will even run on a p4-2ghz
[11:52:37] <Loetmichel> and on 1gb ram
[11:53:18] <archivist> I got some old compaqs the other week, seem ok
[11:53:22] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13089&g2_imageViewsIndex=1
[11:54:11] <Loetmichel> have cramed that industrial board into the base of a small mill for a co-worker
[11:54:16] <Loetmichel> +m
[11:54:27] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13131
[11:54:34] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13149
[11:54:43] <Loetmichel> (lower compartment)
[11:55:56] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13128 <- there you can see the back of the card (missing the slot plate) sticking out
[11:57:35] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13116&g2_imageViewsIndex=1 <- still missing the e-stop-switch ;-)
[11:57:36] <humble_sea_bass> i smell keyboard enthousiast
[11:57:44] <Loetmichel> ?
[11:58:10] <humble_sea_bass> http://www.cyrom.org/palbum/main.php?g2_itemId=13131
[11:58:30] <Loetmichel> these silicon keyboards are great for CNC
[11:58:59] <Loetmichel> waterproof, heat resistant, no openings for swarf to get in and block the keys
[11:59:03] <humble_sea_bass> oh i thought you were cutting keycaps. didn't occur to me that it was a sylicone keyboard
[11:59:16] <Loetmichel> the're not really good fro writing essays, though
[11:59:29] <humble_sea_bass> I'm a crazy person so I use a cherry keyboard on my CNC
[12:00:08] <Loetmichel> humble_sea_bass: my own machine has the same: http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[12:00:45] <humble_sea_bass> i should probably move to ne of those
[12:01:01] <humble_sea_bass> that way I don't have to be all careful
[12:01:55] <Loetmichel> be careful when cleaning it: the cable intake is NOT waterproof
[12:02:27] <davef> Loetmichel: I think I read this box needs low-profile cards... I'm not familiar with those. Would my normal size graphics card wouk in the PCI slot if I just took the case cover off?
[12:02:33] <Loetmichel> but otherwise they are pretty "die hard"
[12:02:47] <Loetmichel> it would
[12:02:55] <Loetmichel> but many cards are low profile
[12:02:58] <Zaaarin> Loetmichel, how about heatlosses through conduction through the ceramic seals and jacket? Howabout heatlosses through convection of air going across the bare metal heat exchange? Pressurelosses through teh tiny gaps in the rotating seals? Inefficiencies in the placement of the mirrors and the dust on the mirrors?
[12:03:07] <IchGuckLive> hi all
[12:03:16] <Loetmichel> it just means they are 23/3 height of the slot plate
[12:03:20] <Zaaarin> Still any ideas how much psi 60ml/sec would do in a 100mm (3inch) diam pipe?
[12:03:34] <Zaaarin> sorry had to bath the baby
[12:03:40] <davef> Oh good! Any suggestion for a low-profile graphics card cheap?
[12:03:47] <Loetmichel> and in the best case you have a differen slot plate with it that ccan be mounted for low profile use
[12:03:58] <Loetmichel> davef: which country?
[12:04:34] <Loetmichel> http://www.pollin.de/shop/dt/NTM0ODkyOTk-/Computer_und_Zubehoer/Hardware/Grafikkarten/Grafikkarte_ATI_Radeon_HD5450_512_MB_GDDR3_passiv.html
[12:04:35] <IchGuckLive> ;-) it is the 5th season Loetmichel all girls are mad today
[12:04:37] <davef> USA
[12:04:47] <Loetmichel> IchGuckLive: sadly, it is
[12:04:57] <IchGuckLive> O.O
[12:05:06] <Loetmichel> davc: soory, i dont know any shops there
[12:05:20] <davef> 'K
[12:05:22] <Zaaarin> loetmichel, you recommend a 512meg!? I'm using 2 gig and I STILL wish I had a more powerful gfx card, still 20 quid is not to be sniffed at
[12:05:23] <Loetmichel> but use any cheap card that looks like this
[12:05:36] <Loetmichel> Zaaarin: for a CNC pc?
[12:05:37] <Loetmichel> why?
[12:06:01] <Zaaarin> depends how complex your designs are and if you're attempting to simulate them real time
[12:06:18] <Loetmichel> on the linuxCNC pc?
[12:06:19] <Loetmichel> why?
[12:06:24] <IchGuckLive> my hole pc is not that vprice of this graphics
[12:06:28] <Loetmichel> dont you have a cad pc for that?
[12:06:37] <IchGuckLive> and im running at 10m7min with no steploss
[12:06:47] <jthornton> more and more added http://www.gnipsel.com/files/g-code-generator/
[12:06:56] <Zaaarin> I got an all in one rig that does everything, very power inefficent, but hey I got 8 cores 32gig of ram I'm not complaining
[12:07:24] <IchGuckLive> Zaaarin: your cnc will use only one core
[12:07:38] <IchGuckLive> get you a cheep pc
[12:08:00] <IchGuckLive> like ibm a50 for 25USD
[12:08:04] <Zaaarin> I suppose if you're making a dedicated rig, yeah don't waste cash on what you don't need heh
[12:08:20] <Loetmichel> Zaaarin: davef wants to know if this box will be good for LinuxCNC: [18:31] <davef> http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?sp4ts.oid=3249646&spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c00809043-33%257CdocLocale%253Den%257CcalledBy%253DSearch_Result&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.po
[12:08:20] <Loetmichel> rtlet.endCacheTok=com.vignette.cachetoken
[12:08:42] <IchGuckLive> you will run in trouble to keep the other cores on interacting your realtime
[12:08:57] <Loetmichel> and we said: yes, it will but you may have issuees with the internal nvidia card
[12:09:16] <Loetmichel> so i reccomended him a cheap solution.
[12:09:42] <Loetmichel> IchGuckLive: thats problems gone since at least 2.5
[12:09:45] <Zaaarin> loet: page won;t load
[12:09:51] <IchGuckLive> Deejay: http://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1313&_nkw=ibm+a50&_sacat=0&_from=R40
[12:10:24] <Loetmichel> Zaaarin: google yourself: [18:31] <davef> Anyone know if this box will run linuxcnc OK? HP DC5700 small form factor computer.
[12:10:39] <Deejay> IchGuckLive?
[12:11:13] <Zaaarin> Single PCI slot?
[12:12:20] <Loetmichel> ahem...
[12:12:30] <Loetmichel> just noticed: that board has agp!
[12:12:43] <IchGuckLive> Deejay: sorry davef
[12:12:54] <Loetmichel> davef: you will have to buy or snatch an AGP card somewhere ;-)
[12:13:21] <davef> On www.hp.com paste this search in the search box to see all the specs of the computer
[12:13:35] <davef> HP Compaq dc5700 Small Form Factor PC - Overview
[12:13:50] <IchGuckLive> davef: http://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1313&_nkw=ibm+a50&_sacat=0&_from=R40 There are no Fujitsus sold in the USA P5915 5925 there are mutch better and also 50USD
[12:14:01] <davef> Loetmichel: Not sure how many PCI slots
[12:14:03] <Loetmichel> davef: i take that back
[12:14:05] <Loetmichel> http://www.quantelectronic.de/Information/content15/HP%C3%9C5700%20SFF.htm
[12:14:09] <Loetmichel> it has pcie
[12:15:22] <Zaaarin> Suppores PCI-E and has two additional PCI slots, for a dedicated LinuxCNCrig I think that's a better buy
[12:15:25] <IchGuckLive> arend thee like here in Germany second IT stores around in main citis
[12:15:47] <davef> I'm getting information overload here... :) Can't keep up!
[12:17:13] <davef> Loetmichel: Thanks for that last link! That helps a lot!
[12:18:16] <Loetmichel> de nada
[12:18:27] <davef> Loetmichel: Sorry, what's that about AGP? Is that accelerated graphics package?
[12:18:34] <Loetmichel> forget it
[12:18:47] <Loetmichel> i misread some information on the net about the box
[12:18:53] <davef> :)
[12:19:41] <davef> What about the dual core processor? Is that going to be a problem?
[12:20:01] <Zaaarin> AGP's basically dead, anything 512meg or higher gfx wise it's all PCI-E nowadays
[12:20:25] <Zaaarin> I'm still cross about VGA and IDE ports being phased out grrr
[12:21:18] <humble_sea_bass> order this man
[12:21:20] <humble_sea_bass> http://www.newegg.com/Product/Product.aspx?Item=N82E16813128561
[12:21:34] <Zaaarin> Anyways, I got to go, thanks for all your help, I'll let you know how well my hunt for a suitable starter pinion from the scrapheap goes tomoz!!!
[12:21:36] <humble_sea_bass> vga, and parallel port
[12:21:36] <Zaaarin> NN guys
[12:22:10] <davef> IchGuckLive: Will I have a problem with the dual core processor?
[12:22:12] <Loetmichel> humble_sea_bass: he already has ordered three of the HPs
[12:22:21] <humble_sea_bass> bummer
[12:22:24] <Loetmichel> davef: no
[12:22:51] <Loetmichel> if you use an up to date lifeCD wou will not
[12:23:08] <Loetmichel> my CNC PC at home is a c2d-3ghz
[12:23:17] <Loetmichel> ... in a VERY small box
[12:23:19] <Loetmichel> ;-)
[12:23:37] <Loetmichel> (used an old 286 "pizzabox" as a case
[12:23:47] <IchGuckLive> Loetmichel: but you need to go frech install from 2.4x
[12:23:50] <davef> Hah.
[12:23:55] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12265
[12:24:00] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12250
[12:24:05] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12247
[12:24:06] <Loetmichel> ;-)
[12:24:56] <davef> Loetmichel: By up to date lifecnc you mean just run the latest version of linuxcnc, right? You're not saying to run emc from a CD ?
[12:25:12] <humble_sea_bass> i've been using ammo cans as cases. they can be had real cheap
[12:25:24] <Loetmichel> i meant: use the latest linuxCNC life CD for installing the ubuntu
[12:25:34] <Loetmichel> and then update the linuxCNC to at least 2.5
[12:25:36] <MarkusBec> I have a AMD FUSION dualcore
[12:25:41] <MarkusBec> it works fine
[12:25:55] <davef> OK, that's what I thought.
[12:25:57] <Loetmichel> humble_sea_bass: i have no vertical room under my CNC
[12:26:01] <davef> Oh Good.
[12:26:16] <Loetmichel> humble_sea_bass: http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[12:26:20] <Loetmichel> see the pizzabox?
[12:26:35] <humble_sea_bass> heh
[12:27:13] <MarkusBec> old atoms and old celerons are pita
[12:27:25] <davef> Anyway I got three puters for $200.00. Tired of having to re-do everything to set up a different box when I have a crash. This way I'll have two identical backup puters
[12:27:28] <humble_sea_bass> is that spray coolant
[12:27:42] <MarkusBec> tonns of interupfs from the BIos
[12:27:47] <Loetmichel> watercooling for the spindle ;-)
[12:28:39] <humble_sea_bass> is that as good as directly spraying the tool and workpiece
[12:28:43] <humble_sea_bass> certainly cleaner
[12:29:36] <Loetmichel> hmm?
[12:29:43] <Loetmichel> it isnt spraying
[12:29:45] <Loetmichel> https://www.youtube.com/watch?v=a9Ov69t0uwo
[12:30:10] <DaViruz> humble_sea_bass: it isn't cooling the tool/workpiece, it's cooling the spindle motor
[12:30:43] <humble_sea_bass> oh, those vfd motors generate a lot of heat?
[12:30:56] <Loetmichel> 800W max the small one
[12:31:26] <Loetmichel> but the watercooled ones are very quiet as you can hear in the video.
[12:31:31] <davef> Loetmichel: Is that mill your creation?
[12:31:36] <Loetmichel> yes
[12:31:52] <davef> Built from scratch?
[12:32:09] <Loetmichel> yes
[12:32:20] <davef> Wow.
[12:32:24] <davef> Nice
[12:34:37] <Loetmichel> its just a few sheets of 8mm aluminium, a few smoot rods, some ballbearings and some steppers and acme threads ;-)
[12:34:43] <Loetmichel> and a sack of screws ;-)
[12:35:41] <davef> LOL
[12:36:12] <davef> Yeah, just collect all that stuff, throw it in a pile, and there ya go.
[12:37:20] <Loetmichel> you forgot: "shake it well!"
[12:37:21] <Loetmichel> ;-)
[12:38:01] <DaViruz> shake, don't stir.
[12:38:48] <davef> Loetmichel: Pretty sure I have Ubuntu 10.4 on my HD Sure it's at least 8.04
[12:39:23] <Loetmichel> davef: if you want to mess around with building your own realtime kernel: use it
[12:39:41] <davef> Eh?
[12:39:45] <Loetmichel> otherwise i would reccomend to do a fresh install from the linuxCNC life CD
[12:40:08] <davef> OK, can you show me a link to download pls?
[12:40:57] <Loetmichel> http://www.linuxcnc.org/index.php/english/download
[12:41:03] <Loetmichel> ... obviously ;-)
[12:42:11] <davef> and then here? http://linuxcnc.org/index.php/english/download/21?task=view
[12:42:31] <davef> and DL the ISO?
[12:43:09] <archivist> get the iso then do the os updates
[12:43:26] <Loetmichel> you could have clicked the link on my link, but yes, that would work also
[12:44:21] <davef> Actually that's what I did.
[12:46:35] <davef> What I meant earlier is, I already had linuxcnc running on on my HD from the old computer. I believe when I installed that I got the one that came with linuxcnc and ubuntu all together on one cd so I'm thinking I have that all done already...
[12:47:00] <Loetmichel> no, you cliecked on "other installation options" instead of "download the iso"
[12:47:12] <Loetmichel> ... which is a direckt link to the iso
[12:47:13] <Loetmichel> ;-)
[12:47:20] <davef> Oh.
[12:47:57] <Loetmichel> i would still reccomend to use a fresh install on the HP boxes
[12:48:09] <brianmorel99> Does anyone have a recommendation for a Video card? I have an Intel 915G chipset motherboard and it's killing the latency test. i swiched to the fbdev which helped, but I'd like to keep the load off the cpu as much as possible.
[12:48:30] <Loetmichel> brianmorel99: any cheap fitting one will do
[12:48:34] <davef> bbl
[12:49:06] <brianmorel99> Any preference between AMD / Nvidia?
[12:51:12] <Loetmichel> not that i know of
[12:55:38] <davef> In the documentation wiki there's some old info - something about nvidia driver needing to be replaced with a different one
[12:55:55] <davef> I'm looking for it...
[12:56:13] <cradek> I have the best luck with old matrox cards (even those original pci ones)
[12:56:27] <cradek> then you avoid both amd and nvidia weirdnesses
[12:56:49] <IchGuckLive> matr is what im using 2 if it doesnnot work
[12:57:32] <IchGuckLive> AGP-Grafikkarte Matrox G450 Dualhead
[12:58:20] <cradek> yep those G5xx and millenium XX all work great
[13:00:39] <davef> I bought a MATROX 844-00 Rev_A card, just plugged it in, and it worked fine on my HP.
[13:01:13] <davef> about 25-30 bucks at a used comp. store but new card.
[13:01:42] <PetefromTn> http://imagebin.org/296166 Well....Let the MODBUS games begin!!!
[13:01:49] <davef> card says copyright 1998 lol
[13:02:43] <cradek> it was a good year
[13:03:44] <davef> Hey Cradek.
[13:06:52] <davef> My old HD is a EIDE and the new boxes have SATA drives. Otherwise I'd try to just plug the old drive into the new puter and go. But is there any simple way to make an image of the old drive on the new SATA drive?
[13:07:37] <cradek> nope, not particularly easy
[13:08:09] <cradek> easiest to just install and copy over your old config directory.
[13:08:22] <davef> OK, fresh install then, and transfer all my configs and code via a flash drive I guess.
[13:08:29] <cradek> there you go
[13:10:35] <davef> Just to be sure- This is what I want, yes? ubuntu-10.04-linuxcnc3-i386.iso
[13:11:34] <davef> The latest LinuxCNC Live version - based on Ubuntu 10.04 Lucid Lynx LTS LiveCD (2012 - April)
[13:11:35] <cradek> yep
[13:13:17] <davef> Thanks! Now I just have GOT to figure out how to keep metal dust and swarf out of my puters! This makes about 5 fried over the sevaral years I've been doing cnc
[13:16:23] <cradek> just putting them higher helps
[13:20:07] <davef> Worst is fine dust from wire wheel. It floats all over the darn place.
[13:23:31] <davef> I'm thinking about building a wood box with a ventilator fan blowing out, and a whole house hypoalergenic furnace filter on the top, sealed.
[13:24:47] <Loetmichel> davef: chicken!
[13:25:20] <davef> Tired of the computer fan sucking everthing it can grab into the puter.
[13:25:21] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=735
[13:25:28] <Loetmichel> yes, thats aluminium...
[13:25:38] <Loetmichel> just ignore it ;-)
[13:26:16] <davef> yup, benn there done that. Five blown MB's later... I want a clean puter.
[13:26:23] <Loetmichel> hrhr
[13:26:29] <Loetmichel> so do as i do at the company
[13:26:49] <davef> whats that
[13:26:56] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13447
[13:27:09] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13450
[13:27:13] <Loetmichel> front filter
[13:27:20] <Loetmichel> changeable from the outside ;-)
[13:28:38] <davef> Whats that, open cell foam?
[13:29:38] <davef> What about air getting in from the back, etc. I'm talkin really fine dust.
[13:29:53] <Loetmichel> inside the aluminium frame is a sheet of these "kitchen cooker hood" stuff
[13:30:08] <Loetmichel> there is no air going in from the back
[13:30:18] <Loetmichel> behind that filter tehre is a big 150mm fan
[13:30:22] <Loetmichel> pressing air in
[13:30:27] <Loetmichel> filtered air
[13:30:57] <Loetmichel> as long as the case has slight overpressure from that fan any other opening will let air out, not in ;-)
[13:31:04] <Loetmichel> just aerodynamics ;-)
[13:31:33] <davef> Davef does his best Homer Simpson...
[13:31:39] <davef> DOH!
[13:31:45] <Loetmichel> hrhr
[13:32:02] <davef> :)
[13:32:22] <Loetmichel> my company makes shielded military PCs
[13:33:04] <Loetmichel> so the get sealed by these "warranty void" type stickers after we measure them to comply with SDIP27
[13:33:16] <Loetmichel> so the customer cant "drust off" the insides
[13:33:24] <Loetmichel> thats the reason for the dust filters
[13:33:41] <davef> Ah. In that case I'll definitely take advice from the voice of experience.
[13:34:26] <Loetmichel> and the big fan inside ;-)
[13:35:12] <Loetmichel> we have made trials: in a normal office you have to change the filters about every 6 months
[13:35:27] <Loetmichel> in afghanistan in the desert: every 7 days ;-)
[13:35:59] <davef> Very good system. I have an old bathroom exhaust fan. I might try basically the same thing but with the filtered fan on the outside of the box. These small form factor jobs are probbaly giong to be pretty packed.
[13:36:03] <Loetmichel> you dont belive what amount of desert sand a normal PC can eat.
[13:36:04] <davef> Hah.
[13:36:18] <Loetmichel> got some back from the army (repair)
[13:36:22] <davef> Oh, I can imagine.
[13:36:44] <Loetmichel> ... first i poured ut about a cup full of sand ;.-)
[13:36:56] <davef> Wow
[13:37:08] <Loetmichel> THEN i blown it out with compressd air
[13:37:14] <Loetmichel> and THEN i repaired it ;-)
[13:37:19] <Loetmichel> every time ;-)
[13:37:19] <IchGuckLive> im off BY
[13:37:28] <davef> Good thing it's not conductive.
[13:37:33] <Loetmichel> hrhr
[13:38:11] <Loetmichel> i've seen laptops that operated on emergency (casing) cooling because both fans were FILLED with sand
[13:38:20] <Loetmichel> literally FULL
[13:38:21] <davef> BTW, speaking of fans, Don't try this at home...
[13:38:41] <Loetmichel> the compresed air?
[13:38:46] <Loetmichel> no problem
[13:38:56] <Loetmichel> just lock it so it cant over-rpm ;)
[13:39:24] <davef> I once blew air from my compressor into my power supply, spinning the cooling fan at a bizillion RPM, fried the whole puter PS a,d all.
[13:39:34] <Loetmichel> ouch
[13:39:57] <davef> Loetmichel: Good guess.
[13:40:56] <Loetmichel> i've made 80mm computer fans literally EXPLODE with a compressed air gun
[13:41:19] <Loetmichel> the desintegrate at about 50krpm (from the sound of it) ;-)
[13:41:28] <Loetmichel> ... on pourpose of course ;-)
[13:41:55] <davef> Yipes!
[13:41:59] <Loetmichel> yes, i am a little careless sometimes.
[13:42:09] <davef> Hey I really appreciate your help today.
[13:42:16] <Loetmichel> my apprentice made a pic seeing me working....
[13:42:37] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12244
[13:42:51] <gonzo__> it's fun to see how fast you can get bearings to go when you are blowing the crape out with an airline
[13:42:58] <gonzo__> sound like a jet engine
[13:43:02] <Loetmichel> ... saying "that will go to my teacher in school. for the "how NOT to do it" Board" ;-)
[13:43:10] <Tom_itx> wait til they sieze up
[13:43:32] <gonzo__> wouldn't do it with ones that were nit on their way to the bin
[13:43:46] <Loetmichel> ... he still helped me extinguishing the trashcan under the workbench afterwards
[13:43:55] <davef> LOL
[13:44:04] <Loetmichel> ... with the fres used paper cloth soaked with ethanol in at ;-)
[13:44:12] <Loetmichel> in it
[13:44:49] <davef> Sure it was just the paper soaked in ethanol Loetmichel ?
[13:44:55] <Loetmichel> it was
[13:44:56] <davef> :)
[13:45:11] <Loetmichel> i used it to clean the sharpie marks off the steel sheet
[13:45:14] <Loetmichel> ;-)
[13:45:28] <davef> Not the operator maybe?
[13:45:41] <Loetmichel> no, thats my normal mode of operation
[13:45:50] <Loetmichel> out of hands, otu of mind ;-)
[13:45:52] <Loetmichel> out
[13:45:52] <davef> Too funny
[13:46:22] <davef> Hey, got to go. Thanks so much.
[13:46:40] <Loetmichel> de nada
[14:05:58] <MrSunshine> hmm working with sheet goods isnt at all fun :P
[14:26:37] <JT-Shop> pcw_home, looks like they might be Nema 34 and the power supply is a toroidal with 45v and 9amp secondary
[16:16:21] <Deejay> gn8
[17:16:57] <PetefromTn> Hey guys got a question, I recently updated to the newest master a couple days ago and today I was trying to load some new tools into the tool table.
[17:17:25] <PetefromTn> The table seems to finally be accessible from the axis UI at any time now which is nice however
[17:17:59] <PetefromTn> I loaded a tool and using my G59.3 tool touch off position I jogged down to the 123 block like I have been doing which works well.
[17:18:20] <PetefromTn> When I touch off to tool table with the new tool the offset is loaded and appears correct.
[17:19:53] <PetefromTn> However I noticed that my tool 1 touch off tool in the table which has an offset of zero does not show a number in the G-edit table nor in the Tool editor in axis. It just shows nothing. Is this normal or is there no offset loaded?
[17:52:29] <JT-Shop> PetefromTn, your question is confusing... can you break the last part up into individual questions?
[18:20:10] <Tom_itx> JT-Shop, sounds like he didn't save and update the table
[18:20:59] <Tom_itx> i think he has been leaving the tool table open in the editor while touching off
[18:34:48] <JT-Shop> not a good idea
[18:34:55] <JT-Shop> did you get 1.7.01?
[18:37:17] <Tom_itx> not yet
[18:40:22] <CHNCguy> hey hey guys! ;)
[18:40:58] <CHNCguy> can anyone point me to a good tutorial on how to tune servos?
[18:41:27] <JT-Shop> velocity or torque mode?
[18:43:58] <JT-Shop> Tom_itx, I added a button to write the G code to a file in .01
[18:44:28] <CHNCguy> well both i suppose :)
[18:45:03] <PCW> Tuning is quite different for velocity or torque mode
[18:45:15] <CHNCguy> I am trying to see if I can retrofit an older moriseiki, with DC servos and drives
[18:45:20] <JT-Shop> ah I only have velocity http://www.gnipsel.com/linuxcnc/tuning/index.html
[18:45:25] <CHNCguy> how would they differ?
[18:45:33] <Tom_itx> gcode or settings?
[18:46:29] <CHNCguy> settings from servo to control to control velocity, toque, critically damped etc...
[18:47:02] <PCW> If your drives have tachometers they are velocity mode drives
[18:47:19] <CHNCguy> can linuxcnc interface with them?
[18:48:29] <PCW> Yes
[18:48:29] * JT-Shop wanders off to whoop up some gumbo
[18:48:41] <JT-Shop> goodnight
[18:48:51] <CHNCguy> night
[18:49:11] <PCW> 'nite JT
[18:49:13] <PCW> typically velocity mode drives are easier to tune
[18:49:29] <CHNCguy> so i am looking at JT's tutorial, not really understanding how to change the setting to effect the curve
[18:50:43] <CHNCguy> is there a vid of tuning?
[18:51:13] <PCW> different settings affect different parts of a motion profile
[18:52:25] <CHNCguy> so these are the bars on the right correct?
[18:53:19] <CHNCguy> the gain/pos?
[18:53:28] <PCW> those are the scope settings if we are on the same page...
[18:54:02] <CHNCguy> ya i figured that...after i typed it LOL
[18:54:17] <CHNCguy> so where are the P FF1 and FF2 changed at?
[18:54:31] <PCW> Typically you would use the "calibrate" menu in Axis for servo tuning
[18:54:50] <PCW> Do you have linuxcnc running?
[18:55:26] <CHNCguy> not this second, its in the shop just wanting some base info before I got started ;)
[18:55:49] <CHNCguy> would calibrate automatically do it for each axis?
[18:56:28] <PCW> its all manual (but calibrate has tabs for each axis)
[18:59:01] <CHNCguy> cool, ill have to play with it while I get back there.
[18:59:03] <PCW> much easier to understand with the tools in front of you...
[19:00:13] <CHNCguy> Also I would like to hire someone to make me a custom screen set for a 3axis mill, anyone interested? I would just explain what I would like on the screen, and where. They do the rest.

[20:13:09] <PetefromTn> Ola'
[20:13:24] <jdh> como esta
[20:13:32] <PetefromTn> muy bein y tu?
[20:13:40] <jdh> bitchin'
[20:13:45] <PetefromTn> LOL
[20:14:05] <PetefromTn> I could not get on here for awhile today not sure what the hell was going on?
[20:14:22] <jdh> govt. trying to keep you down.
[20:14:33] <PetefromTn> and the Logger Mah thing keeps saying file not found...
[20:14:38] <PetefromTn> probably...
[20:14:43] <PetefromTn> fuckers..
[20:15:25] <PetefromTn> did I miss anything interresante?
[20:16:36] <PetefromTn> Connor: Ya there man?
[20:19:33] <Tom_itx> tons
[20:19:47] <Tom_itx> you know there are more than one log bot right?
[20:19:47] <PetefromTn> do tell...
[20:20:00] <PetefromTn> yeah I tried both the logger ones..
[20:20:06] <Tom_itx> zlog_
[20:20:09] <PetefromTn> both say not found..
[20:22:01] <PetefromTn> Looks like the posts I made earlier about the tool table actually did go thru. My quassel was behaving wierd today and I figured I was not actually online. Apparently I was.
[20:22:21] <PetefromTn> Some folks responded but I waited on my end for a long time and never saw any responses...
[20:23:23] <PetefromTn> Did you see it Tom?
[20:24:04] <Tom_itx> not sure, been kinda busy here today
[20:24:56] <Tom_itx> now i gotta restart the router...
[20:24:57] <Tom_itx> brb
[20:34:41] <Tom_itx> PetefromTn are you setting the tools with the tool editor or gedit open?
[20:42:43] <PetefromTn> either..
[20:43:13] <Tom_itx> ?
[20:43:15] <PetefromTn> before I was opening the Geditor and touching off with it open and it worked just fine that way.
[20:43:38] <Tom_itx> not a good idea to set tools with it open
[20:43:51] <PetefromTn> Today I did it with the tool table editor and whether it was open or not did not seem to matter. It still loaded the new tools fine.
[20:43:56] <PetefromTn> why not?
[20:44:53] <Tom_itx> i've had bad results with it open too
[20:44:55] <PetefromTn> besides that is not what the problem was. For some reason with the new setup when I input a new tool or actuall I was changing tool holders today and inputting a new TLO for an existing tool.
[20:45:22] <PetefromTn> For some reason my tool 1 which I did not modify shows NO TLO just blank.
[20:45:38] <PetefromTn> Not anything in the tool editor nor in Gedit..
[20:45:48] <Tom_itx> we set our tools up differently so i'm not gonna offer advice
[20:45:52] <PetefromTn> I was wondering if that is normal or a change they made..
[20:46:11] <PetefromTn> why?
[20:46:15] <Tom_itx> i haven't had any problems in master either
[20:46:35] <Tom_itx> i'm running 2.5.3, master and the new TP code
[20:47:43] <Tom_itx> [18:20:59] <Tom_itx> i think he has been leaving the tool table open in the editor while touching off
[20:47:44] <Tom_itx> [18:34:48] <JT-Shop> not a good idea
[20:53:53] <PetefromTn> okay then.
[20:53:54] <skunkworks> Tom_itx: any feedback on the new TP?
[20:54:59] <Tom_itx> i honestly haven't run any code on the machine with it yet
[20:55:48] <Tom_itx> what sort of a setup do you have for testing it?
[20:56:55] <skunkworks> well - i have simulating 99% so far.. but I did get to run one of the emco lathes with it. threading still works :)
[20:57:21] <skunkworks> I have a stepper router I have it built for - but have not found the time to actually run the machine
[20:57:56] <skunkworks> it is not going on the k&t yet... :)
[20:58:10] <Tom_itx> i've got some things that are gonna tie me up til after next week but i'd like to try running some code thru it soon
[20:58:50] <Tom_itx> how do i set the limits in sim so i don't get limit errors?
[20:58:59] <Tom_itx> i think it's reading my sherline setup...
[21:00:36] <Tom_itx> i tried loading the spiral example and maybe a couple others and kept getting limit errors
[21:01:31] <Tom_itx> i didn't check to see the required work area for them though..
[21:02:51] <uw> i think it's tied to your machine file
[21:03:19] <uw> maybe make the travel box larger or at the correct location
[21:03:42] <Tom_itx> i may have to make a different config for it
[21:03:54] <Tom_itx> i'm not gonna change the working ini
[21:05:54] <Tom_itx> looking at the changelogs, he's done quite a bit wiht it
[21:09:47] <skunkworks> tons.. yah - just copy your config and modify it.
[21:10:07] <skunkworks> add the lookahead stuff and increase your min and max limitss
[21:13:45] <Tom_itx> should i use the defaults you pasted me a while back?
[21:13:56] <Tom_itx> not knowing what they should be..
[21:14:29] <Tom_itx> is the OPTIMIZATION_DEPTH the lookahead buffer?
[21:15:17] <Tom_itx> and what is the SMOOTHING_THRESHOLD? the allowable deviation?
[21:15:22] <Tom_itx> in what units...
[21:33:30] <skunkworks> Tom_itx: yes. I am not sure exactly what the smoothing_threshold is.. I think it is what percentage of the segment is gobbled up by blending.. But I have tried both .4 and .75 and don't see a time change. maybe the sound might be different
[21:34:29] <Tom_itx> how big a lookahead have you tried?
[21:35:01] <Tom_itx> and is that number gcode lines or something else?
[21:35:18] <Tom_itx> 50 lines in a surface file is nothing
[21:47:25] <skunkworks> I have not had more than 50 increase the speed.
[21:47:29] <skunkworks> so far.
[21:48:16] <Tom_itx> is that lines of code or some other buffer size?
[21:49:18] <skunkworks> segment look ahead I think
[22:00:26] <Tom_itx> if i put the configs in the bin directory will it look for them there before it sees my normal cofigs?
[22:00:30] <Tom_itx> configs*
[22:00:38] <skunkworks> I thought I found 2 bugs.. (not following path and rfl not running correctly) but It was me.. I had set the G64 tolerence before G21.. rfl was because there was no Z in the whole section of code. so it ran the program where z was setting - not where the program was.
[22:00:56] <skunkworks> it should show both...
[22:01:48] <skunkworks> 'my configureations' are what are in the linuxcnc directory.. Then The 'sample configs' should be in your rip directory.
[22:06:04] <Tom_itx> do i need to edit the rip-environment file?
[22:07:15] <skunkworks> this look interesting.. http://www.youtube.com/watch?v=08NMlUfdW8Q
[22:07:28] <skunkworks> have to ask garret about that video
[22:07:33] <skunkworks> Tom_itx: what do you mean?
[22:07:41] <Tom_itx> i don't think i do...
[22:07:49] <Tom_itx> looks like the paths are set ok
