[02:17:06] <Deejay> moin
[05:03:45] <jthornton> morning
[07:53:22] <skunkworks> http://electronicsam.com/images/control.jpg
[08:01:44] <Tom_itx> i'm glad you know where all those wires go
[08:02:19] <jdh> that is an impressive number of spaghettified wires
[08:03:59] <skunkworks> that was final disassembly...
[08:04:50] <mozmck> skunkworks: I was told you have an acroloc mill?
[08:05:09] <skunkworks> yes
[08:05:22] <skunkworks> non working recent purchase...
[08:05:38] <mozmck> Is it a pretty good machine? There is one near me with no tooling.
[08:06:33] <skunkworks> well - it is odd.. Some people like them from what I have read. The tooling is totally non standard. (we got a bunch when we purchased it)
[08:07:18] <skunkworks> they are, from what I have read, pretty darn fast
[08:08:16] <mozmck> non-standard tooling - makes this one not too interesting since there is none with it.
[08:09:24] <skunkworks> they look like hockey pucks
[08:09:47] <skunkworks> http://www.acroloc.com/Acroloc/Acroloc%20Tooling.htm
[08:10:37] <skunkworks> needless to say we have a matsuura that we will convert before the acroloc
[08:11:38] <mozmck> Do y'all have work for those machines or are you just having fun?
[08:12:02] <eric_unterhausen> how does that tooling work?
[08:12:19] <skunkworks> the layout is sort of odd also. It is sort of like a knee mill with a quill - except instead of the knee moving up/down the sindle unit moves up and down.
[08:12:38] <eric_unterhausen> haas does that on their toolroom mill
[08:12:40] <skunkworks> mozmck, mostly for fun. Dad is retired.
[08:12:49] <skunkworks> (and I have a DayJob)
[08:14:05] <mozmck> I see. I have plenty to do, but I would like to find and convert a small vmc to linuxcnc sometime. I can find stuff to do with it I'm sure.
[08:14:43] <skunkworks> dad just got this - it is much sexier.. http://imagebin.org/287781
[08:15:12] <Tom_itx> yeah i remeber seeing that one
[08:15:17] <eric_unterhausen> you think that was the stock color?
[08:15:21] <Tom_itx> +m
[08:15:23] <skunkworks> I think so
[08:15:27] <eric_unterhausen> needs flames or racing stripes
[08:15:36] <skunkworks> or devil horns
[08:15:45] <Tom_itx> i googled other pics of that model and they were red as well
[08:15:51] <eric_unterhausen> or several sets of devil horns
[08:15:51] <mozmck> hmm, that's larger than I want. My boss is scrapping out a leadwell about that size.
[08:16:14] <skunkworks> well - the acroloc we have is quite a bit bigger
[08:16:20] <mozmck> interesting.
[08:16:22] <skunkworks> footprint wize
[08:16:28] <eric_unterhausen> work has a centroid that color
[08:16:30] <mozmck> the one here looks a good bit smaller.
[08:18:35] <mozmck> skunkworks: http://dallas.craigslist.org/ndf/for/4256424656.html
[08:19:54] <eric_unterhausen> too bad about the tooling, looks like it's scrap
[08:20:21] <Tom_itx> skunkworks, you're not running production on them?
[08:20:32] <Tom_itx> that's alot of machine to have sitting around :)
[08:21:51] <skunkworks> mozmck, similar.. but it is missing all the coolant control tin..
[08:22:23] <mozmck> hmm
[08:22:40] <skunkworks> I thought I had pictures of ours..
[08:22:43] <skunkworks> hold on
[08:23:16] <skunkworks> Tom_itx, agreed :)
[08:23:44] <skunkworks> I hate when I put photos onto imagebin and not my website
[08:25:05] <mozmck> don't worry, I don't think I'm interesting in this one.
[08:25:14] <mozmck> interested even...
[08:26:18] <Tom_itx> wtf were they thinking when they made that tooling?
[08:27:21] <skunkworks> mozmck,
[08:27:23] <skunkworks> http://imagebin.org/288143
[08:27:40] <skunkworks> Tom_itx, seemed like a good idea at the time?
[08:28:19] <cradek> do people really take running machines out of service, or is that always a lie?
[08:28:31] <Tom_itx> they do
[08:28:41] <cradek> and then discard all the tooling
[08:28:47] <Tom_itx> not usually
[08:29:05] <Tom_itx> usually a shop will keep it and use it on another machine if they have one it fits
[08:29:35] <Tom_itx> ours were either 40 or 50 taper
[08:29:43] <Tom_itx> among several machines
[08:30:25] <Tom_itx> about the only thing ever changed were the retention knobs
[08:30:27] <skunkworks> we are used to odd tooling.. The k&t has non standard tooling also - but we got a bunch
[08:30:38] <cradek> yeah I bet knobs never match
[08:30:48] <cradek> might actually be worse to have the taper match but not the knob
[08:31:00] <cradek> if it's totally different at least you won't get them confused
[08:31:04] <Tom_itx> we kept tool racks by each machine
[08:31:41] <Tom_itx> so if you borrowed a holder you knew
[08:32:16] <Tom_itx> most cases the same jobs ran on the same machines so there wasn't alot of swapping
[08:32:48] <Tom_itx> ie you wouldn't run tungsten on a machine with a high speed spindle
[08:33:15] <Tom_itx> and you'd be foolish to run aluminum on a 'workhorse'
[08:34:09] <mozmck> cradek: I remember you have a smaller vmc - what make and model is it?
[08:35:55] <cradek> mori seiki MV Jr.
[08:40:35] <Tom_itx> nice machine
[08:40:50] <cradek> yeah, it's really great
[08:41:05] <Tom_itx> what do you do with it?
[08:41:23] <cradek> recently it holds down the floor for me
[08:41:35] <Tom_itx> you're not running production with it then?
[08:41:47] <cradek> nope
[08:41:50] <Tom_itx> "experimental"
[08:42:36] <Jymmm> cradek: pm?
[08:42:43] <skunkworks> Tom_itx, What is this 'production' thing you keep talking about?
[08:43:19] <mozmck> making millions of parts :)
[08:45:43] <Jymmm> cradek: Do you know if PS has the ability to read from an external file or be able to have parameters passed to it externally somehow?
[08:46:54] <PetefromTn> Just logged in what are we talking about here?
[08:48:26] <skunkworks> PetefromTn, machines with odd tooling... (like acroloc...)
[08:48:46] <PetefromTn> aah,
[08:48:50] <skunkworks> and why we have cnc machines and not doing production with them.. Pete! this means you!
[08:48:55] <PetefromTn> What is chris saying is really great?
[08:49:28] <balestrino> i'm following gmoccapy wiki page instructions and i'm stuck at change.ngc file
[08:49:50] <PetefromTn> Acroloc has that funky round puck style tooling right..
[08:50:00] <skunkworks> right
[08:50:05] <balestrino> wiki says to uncomment lines 49 and 50 but my change.ngc contains only a few lines.
[08:50:54] <skunkworks> balestrino, I would make a guess that no one on right now has used gmoccapy.. You might want to post on the forum...
[08:53:27] <PetefromTn> Just looked at the logs. Apparently he was talking about his MV junior... Interesting machine is that the blue and white one?
[08:55:01] <skunkworks> http://geektrap.com/bill-files/01248711886/dscn8000.resized.jpg
[08:55:18] <skunkworks> it is blue and white
[08:56:07] <PetefromTn> Ooh pretty....!!
[08:57:24] <PetefromTn> Does it make a huge mess with the short enclosure walls? I know my machine has full enclosure with open top and it still occasionally sprays coolant out when I hit just the right pocket or something LOL
[08:58:57] <balestrino> skunkworks, ok. I'm new to linuxcnc but gmoccapy seems to be a good interface, do you?
[08:59:28] <balestrino> is a good interface to start to work on?
[09:07:57] <skunkworks> do you mean to use - or modify?
[09:10:31] <balestrino> both. Seems clear and organized and, as little as i know, easy modifiable adding tabs from ini file (with glade/python)
[09:14:10] <skunkworks> balestrino, have you looked through http://linuxcnc.org/index.php/english/forum/41-guis/26314-gmoccapy-a-new-screen-for-linuxcnc
[09:15:08] <balestrino> only a few pages. it's a huge topic :) but i'm going to read all posts
[09:15:28] <skunkworks> someone may have already addressed your problem.. If not - I would post there..
[09:16:02] <balestrino> ok thank you
[09:16:53] <skunkworks> heh - sorry I could not be of more help... (I use axis)
[09:18:05] <balestrino> axis is the "basic" linuxcnc interface?
[09:20:36] <skunkworks> heh - basic.. it is a pretty popular one.
[09:20:37] <skunkworks> http://electronicsam.com/images/KandT/conversion/testing/Screenshot-axis.ngc%20-%20AXIS%202.5.0~pre%20on%20HM2-Servo.png
[09:20:54] <cradek> AXIS is probably the one we think of as the reference implementation today
[09:51:36] <CaptHindsight> mozmck: http://www.ebay.com/itm/ACROLOC-M12-TOOL-HOLDERS-MANY-SIZES-AVAILABLE-/220088199124?pt=BI_Tool_Work_Holding&hash=item333e4767d4
[09:54:12] <CaptHindsight> several others starting ~$25 ea
[09:55:10] <CaptHindsight> http://stores.ebay.com/The-JAB-Machinery-Sales-Store/ACROLOC-TOOLING-/_i.html?_fsub=2832968&_sid=4041463&_trksid=p4634.c0.m322
[10:15:04] <PetefromTn> Jeez thats pretty reasonable... I wish I could buy decent quality Cat40 for that price LOL..
[10:24:46] <CaptHindsight> depending on budget, time, skill and tools available one could swap the spindle for Cat40
[10:32:18] <CaptHindsight> http://www.ebay.com/bhp/cat-40-spindle interesting, by just looking at the spindles you can tell why some machines work better and last longer than others
[11:11:15] * Loetmichel just made a notebook-psu-enclosure for extented temperature range... what a PITA to mill the upper body out of 4mm aluminium -> http://www.cyrom.org/palbum/main.php?g2_itemId=14595
[11:12:27] <archivist> get a bigger machine
[11:13:35] <balestrino> i dont know how to configure motion.probe-input (in simulator)
[11:46:47] <PetefromTn> Loetmichel looks nice man...
[11:47:33] <PetefromTn> Wish my CNC had a cartridge spindle... Would be a helluva lot easier to R and R the bearings.
[11:51:22] <jdh> wish my cnc had a bigger bed, more rigid everything, faster spindle, servos, and a cartridge spindle.
[11:56:38] <Loetmichel> jdh: me too
[11:56:39] <Loetmichel> ;-)
[11:57:15] <Loetmichel> PetefromTn:its for military use in the desert
[11:57:29] <Loetmichel> the notebook will be modified accordingly ;-)
[11:58:06] <CaptHindsight> http://www.ebay.com/itm/370770474504 $1,250.00 CNC 4-HEAD ROUTER
[11:58:12] <PetefromTn> Nice.... Interesting projects you seem to get to work on anyways..
[11:59:29] <PetefromTn> That is an interesting CNC router. Looks like it runs on thomspson style shafting and bearing blocks. You sure could not build one for that money.
[12:00:12] <pcw_home> 4000 lbs!
[12:00:27] <CaptHindsight> sturdy base
[12:02:21] <pcw_home> manual Z axis?
[12:02:27] <jdh> is that a vacuum table? 3 spindles?
[12:02:46] <CaptHindsight> http://www.ebay.com/itm/201010049180 $1,325.50 CNC 5 Axis Engraver Engraving Machine Router
[12:03:15] <CaptHindsight> thats pretty low priced for 5 axis
[12:03:30] <CaptHindsight> 4 spindles
[12:04:13] <CaptHindsight> and it a also says 3, looks like 3 in the pic
[12:05:22] <jdh> I was planning on buying a 6040 base soon, but FedEx broke something I sold/shipped and I have to refund.
[12:05:51] <CaptHindsight> I asked the seller for more info but so far have been ignored
[12:07:33] <CaptHindsight> Repeat positioning accuracy 0.01mm, precision 0.02MM for the HY-3040
[12:09:32] <CaptHindsight> transmission ratio 1:6, Work axis stepper: 200 pulses / 360 degrees, the entire 40-step driving pulse / 1MM
[12:10:59] <CaptHindsight> so 6x the accuracy if you take out the transmission?
[12:12:08] <IchGuckLive> hi all B)
[12:13:25] <IchGuckLive> einar_: ?
[12:37:26] <CaptHindsight> IchGuckLive: http://www.ebay.com/itm/261366501952 do you use similar
[12:39:19] <IchGuckLive> yes
[12:39:31] <IchGuckLive> i use T10 on the big mashines
[12:39:43] <IchGuckLive> so i can go for accurate stepping
[12:40:34] <IchGuckLive> CaptHindsight: module always gives you PI
[12:43:31] <IchGuckLive> CaptHindsight: in your case 1.5+20=30 *Pi = 94.24777mm/U at 400Steps 0,2356 per step
[12:43:50] <IchGuckLive> or at 800 0,117
[12:44:01] <IchGuckLive> so direct drive is good for plasma
[12:44:47] <IchGuckLive> 1.5*20 ! O.O
[12:46:43] <IchGuckLive> CaptHindsight: the metric ones gives you accurat 0.01 following numbers
[12:47:14] <CaptHindsight> I'd be using servos and 1 or 5um linear encoders
[12:47:14] <IchGuckLive> Einar__: ?
[12:47:55] <IchGuckLive> CaptHindsight: on medical mashines but not on plasma
[12:59:57] <CaptHindsight> http://www.ebay.com/itm/121257620023 turns any wooden pallet into a cnc router
[13:00:06] <CaptHindsight> what it looks like anyway
[13:01:21] <Jymmm> That's a sotted sacraficial top =)
[13:01:26] <Jymmm> slotted*
[13:01:28] <IchGuckLive> wear things sometimes people make to get there router going
[13:02:23] <Loetmichel> Jymmm: mine looks not as good anymore ,-)
[13:02:48] <Jymmm> Loetmichel: Mine looks like termite trails
[13:03:10] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14517
[13:04:03] <archivist> expensive scrap wood
[13:04:08] <Jymmm> http://oi51.tinypic.com/28lrg9u.jpg
[13:04:30] <CaptHindsight> http://www.surpluscenter.com/Power-Transmission/ACME-Thread-Lead-Screw-Nuts/ACME-Thread-Lead-Screws/ just FYI, for ACME screws at low prices
[13:06:18] <IchGuckLive> Jymmm: what is the white tube on top of Z
[13:07:21] <Loetmichel> counter weight for less play in z i would guess ;-)
[13:08:20] <uw> how well do those gantry mills work at cutting metal?
[13:08:21] <Jymmm> IchGuckLive: It holds the excess spindle (router) power cord. I ran 120VAC power directly to it (the orange thing), that way, if you still want to use the router manually, you can easily pull it out without having to mess with UNrouting the wiring from the energy chain/split loom tubing.
[13:08:25] <uw> has anyone tried?
[13:09:04] <Loetmichel> uw: did you see the psu enclosure earlier?
[13:09:14] <Loetmichel> thats made on the mill in my last pic ,-)
[13:09:29] <uw> http://www.cyrom.org/palbum/main.php?g2_itemId=14517 <this one?
[13:09:42] <Loetmichel> yes
[13:09:57] <Loetmichel> but there it is modified to "horizontal mill"
[13:10:24] <Loetmichel> thats the normal configuration: http://www.youtube.com/watch?v=hnjHd69saXs
[13:10:33] <Loetmichel> and 4mm sheet aluminium
[13:10:36] <uw> lol i see
[13:10:44] <uw> i just realized that is horizontal
[13:11:22] <uw> i do want gantry mill some day, mostly because it can become laser cutter pretty easily
[13:11:31] <IchGuckLive> Loetmichel: Das teil ist richtig schön geworden
[13:12:15] <IchGuckLive> uw i work with stepper gantrys
[13:12:19] <Loetmichel> uw: i had to mill some key and plug hole in the side of that 1mm steel frame
[13:12:23] <IchGuckLive> plasma on top
[13:12:24] <Loetmichel> 50 times
[13:12:26] <archivist> uw just make yours very much more rigid that others do for meaty bites in metal
[13:13:04] <Loetmichel> so i went "hacking" and pulled a solution out of my a** ;-)
[13:14:05] <IchGuckLive> Loetmichel: why are there som many workstations in the shop Education use
[13:14:54] <Loetmichel> `
[13:15:00] <Loetmichel> IchGuckLive: hmm?
[13:15:52] <Loetmichel> which pic?
[13:17:34] <IchGuckLive> caos
[13:18:11] <Loetmichel> hrhr
[13:18:17] <Loetmichel> we make them
[13:18:43] <Loetmichel> i.e: we buy workstations and modiufy them to be RF-silenced (no eavesdropping)
[13:18:46] <uw> archivist, someday in the future...it's a "down the line" project
[13:18:50] <uw> like many i have
[13:18:53] <Loetmichel> for military and services use
[13:19:12] <Loetmichel> we= the company i work for
[13:19:23] <IchGuckLive> ;-)
[13:19:29] <Loetmichel> there are photos with more
[13:19:49] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13483
[13:19:55] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13486
[13:20:01] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11948
[13:20:06] <Loetmichel> ... any questions?
[13:20:07] <Loetmichel> ;-)
[13:20:16] <Tom_itx> just one
[13:20:19] <Tom_itx> where's mine?
[13:21:28] <Loetmichel> tom: you dont want to pay our prices ;-)
[13:22:32] <PetefromTn> You could give us all one.....I mean ya got so many there LOL
[13:23:33] <uw> Loetmichel, everybody wants something for free LOL
[13:23:38] <IchGuckLive> Loetmichel: looks like my education rooms with 25
[13:26:55] <Loetmichel> for example:we bought these boxes at about 450 eur each.
[13:27:12] <Loetmichel> and sold them at just shy of 2keur ;)
[13:28:10] <Loetmichel> and thats bareley worth the work and the material that we put in there
[13:28:52] <Loetmichel> our flagship system is about 16 to 18keur depending on configuration.
[13:29:14] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12010
[13:29:17] <Loetmichel> ;-)
[13:30:17] <Loetmichel> its certified shielded to Sdip27 level A ;-)
[13:37:24] <IchGuckLive> BYE
[13:39:55] <uw> looks nice Loetmichel
[13:40:30] <Loetmichel> PC shell is made of 3mm aluminium, all seams welded shut ;-)
[13:41:12] <uw> 3mm? is that .22LR bullet proof? :P
[13:41:26] <Loetmichel> may be
[13:41:47] <Loetmichel> but its made this way to be "eavesdropping-proof" not bulletproof ;)
[13:42:08] <Loetmichel> it just dont emits eny RF any more ;-)
[13:49:07] <paul> Stepconf bringt Fehlermeldung »/usr/bin/../linuxcnc-wizard.gif« , was soll ich tun?
[13:50:01] <uw> so many germans in here
[13:52:35] <cpresser> uw: we are going to take over the world soon. out secret moonbase is ready :)
[13:53:04] <DaViruz> third time's the charm? ;)
[13:53:38] <uw> cpresser, I know i saw the movie D:
[13:53:52] <cpresser> uw: documentary! :D
[13:53:57] <uw> LOL
[13:58:36] <Loetmichel> DaViruz: exactly ;-)
[14:03:29] <Loetmichel> DaViruz: "if at first you dont succeed, try again with greater speed!" ;-)
[14:04:04] <DaViruz> you could say blitz-speed :)
[14:04:26] <uw> Tiger II doesnt need porsche suspension :D
[14:04:42] <uw> make ballbearings deep underground
[14:51:49] <MrSunshine> hmm, 0.08mm runout on the new spindle ... china <3
[14:51:49] <MrSunshine> oh well, it was cheap =)
[15:01:42] <MarkusBec> MrSunshine: in most cases the problem is not the spindle
[15:02:43] <MarkusBec> the problem are the cheap collets
[15:08:44] <MrSunshine> MarkusBec, gonna do more measurments of the actual bore etc tomorrow, right now ive just checked with a routerbit in a collet
[15:09:09] <MrSunshine> hopefully that is the case, rather buy a few collets (mostly using 6 and 8mm) than a whole new spindle :P
[15:32:24] <MrSunshine> says runout tolerance of 0.015mm on the collets .. but then again, its china and its ebay
[15:32:28] <MrSunshine> can be 0.15mm :P
[15:33:55] <MrSunshine> http://www.youtube.com/watch?v=Y9-kFItRN3E hehe it sounds a bit unhappy ... quite high volume so turn it down a bit :P
[15:37:24] <jmasseo> .08mm seems like a lot
[15:39:59] <Loetmichel> MrSunshine: that chirp sounds are "wobble" somewhre in the spindle or its mount
[15:40:15] <Loetmichel> have you checked for loose bearings?
[15:40:28] <MrSunshine> well gonna check it more before i decide to regrind it anyhow =) like MarkusBec said .. to check the runout of the bore
[15:40:53] <Loetmichel> i.e can you move the collet sideways while the axes are locked?
[15:41:07] <MrSunshine> ehm ? the collet ?
[15:41:10] <MrSunshine> the spindle ?
[15:41:24] <Loetmichel> the tip of the spindle
[15:41:32] <Loetmichel> try do move it around
[15:41:36] <MrSunshine> Loetmichel, first, what bearings are you talking about
[15:41:40] <MrSunshine> in the spindle or in my machine ?
[15:41:41] <Loetmichel> so to see if you have play somwhre in there
[15:41:52] <jmasseo> how do you select which chinese spindle to buy?
[15:41:52] <Loetmichel> all of them
[15:41:56] <jmasseo> i assume there are lots of different ones
[15:42:14] <MrSunshine> Loetmichel, thing is that the machine is built lik a mechmate .. if i put force on any axis it WILL move some
[15:42:54] <Loetmichel> the chirp is a sign of the mill bit rattling around in its cut
[15:43:10] <Loetmichel> so there has to be sort of "play" in your setup
[15:43:19] <Loetmichel> or some "non-rigidity"
[15:43:46] <MrSunshine> mm gonna check some, thanks for the tips .. hell ic ant even remember if i have tightened down the Z axis to the X axis :P
[15:43:47] <MrSunshine> hehe
[15:43:50] <Loetmichel> oh, you mean: build in rattle?
[15:44:15] <MrSunshine> Loetmichel, mechmate works on V groove bearings ... so if you push something it will climb the groves
[15:44:15] <jmasseo> http://www.ebay.com/itm/Hot-2-2KW-Engraving-Grinding-Water-Cooled-Motor-Spindle-VFD-Inverter-Converter-/111261214455?pt=LH_DefaultDomain_0&hash=item19e7af66f7
[15:44:16] <MrSunshine> =)
[15:44:19] <jmasseo> there is no way this is 3hp.
[15:44:28] <jmasseo> i guess water cooled though
[15:45:13] <Loetmichel> jmasseo: why not?
[15:45:21] <Loetmichel> MarkusBec has one of these.
[15:45:23] <jmasseo> kind of small isn't it?
[15:45:40] <Loetmichel> and i have a few of the 800W types
[15:45:46] <Loetmichel> they are even smaller
[15:45:46] <MrSunshine> Loetmichel, and its a quite long bit also, 5mm wide and 25mm long .. dont know if that should make a diff but at 4mm cut depth it feels like that poor thing will have to take some force :P
[15:46:04] <Loetmichel> MrSunshine: i wpuld think so
[15:46:07] <Loetmichel> would
[15:46:15] <Loetmichel> cant pit it in deeper?
[15:46:20] <Loetmichel> (into the collet)
[15:46:26] <MrSunshine> its as deep as it goes
[15:46:34] <jmasseo> would make a sweet router spindle i suppose.
[15:46:38] <MrSunshine> 8mm shank, 5mm cutter and 25mm long cutting edge
[15:47:17] <Loetmichel> jmasseo: these chinese spindles can have pretty bad bearings and rumout, but the power is delivered
[15:47:24] <jmasseo> right
[15:47:29] <Loetmichel> never seen one that wasnt up to the advertized power
[15:47:30] <jmasseo> well for $300 with the vfd for 3hp
[15:47:53] <jmasseo> i'd like to do a build or conversion one of these days
[15:48:07] <Loetmichel> my home macshine hs a 800W water cooled also
[15:48:17] <jmasseo> are these routers?
[15:48:31] <jdh> 65mm 800w?
[15:49:00] <Loetmichel> http://www.youtube.com/watch?v=a9Ov69t0uwo
[15:49:14] <Loetmichel> jdh: exactly
[15:50:29] <jdh> the yoo-cnc frame-only has a 65mm mount. I was looking for a 1.2kw spindle though. They all seem to be 80mm
[15:50:53] <MrSunshine> oh well, got some work ahead of me tomorrow to see if i can locate instabilities etc in the machine =) now some supernatural and sleep =)
[15:54:28] <heathmanc> You around PCW?
[16:30:15] <Deejay> gn8
[16:38:58] <CaptHindsight> http://www.ebay.com/itm/360639633248 lower grade and cost ballscrew positioners are starting to show up on ebay
[16:39:53] <heathmanc> wish they were a little beefier
[16:40:20] <heathmanc> been looking for a decent z axis for my router
[17:59:16] <JT-Shop> a John Deere 350B followed me home after work
[17:59:19] <JT-Shop> http://imagebin.org/288217
[18:00:37] <Tom_itx> for scraping the snow off the walk?
[18:03:24] <JT-Shop> walk... we don't have any sidewalks out here
[18:04:03] <Jymmm> JT-Shop: does it work?
[18:04:26] <JT-Shop> yea, can't you see all the track marks?
[18:04:58] <Jymmm> JT-Shop: Sure, but you could hve pushed it there with the other tractor as you were unloading it from the transport
[18:05:57] <JT-Shop> you don't push a dozer Jymmm unless you have a bigger doZer
[18:05:57] <Jymmm> JT-Shop: very cool, how much?
[18:06:10] <JT-Shop> NTKB
[18:06:32] <Jymmm> BNTK you mean?
[18:06:47] <Jymmm> JT-Shop: I have no cle what used dozers go for
[18:06:52] <Jymmm> clue*
[18:07:10] <Jymmm> I'd guess under $5000
[18:07:10] <Tom_itx> are you shopping for one?
[18:07:29] <Jymmm> Tom_itx: Wishful thinking
[18:07:39] <JT-Shop> dozers are more expensive than backhoes
[18:07:57] <Jymmm> JT-Shop: but cheaper than wives =)
[18:08:55] <JT-Shop> depends on your wife
[18:09:18] <JT-Shop> mine brings home the bacon and other groceries
[18:09:45] <Jymmm> Ok, cheaper than an EX wife, how's that?
[18:10:10] <uw> true^
[18:10:21] <JT-Shop> yep, that be true
[18:10:28] <CaptHindsight> http://www.asrock.com/mb/overview.asp?Model=E350M1 <7K nS with factory BIOS and old 10.04 install + upgrade to emc 2.5
[18:10:32] <Jymmm> uwe_: <--- poor bastard (srry to hear that)
[18:11:22] <Tom_itx> it costs more after they leave?
[18:12:01] <CaptHindsight> mine still owes me money!
[18:12:10] <uw> no i'm not victim but i've heard stories
[18:12:30] <Jymmm> uwe_: You think so huh?
[18:12:32] <CaptHindsight> uw = uwe?
[18:14:37] <uw> i think so
[18:15:09] <uw> my good friend got rocked by some crazy "c" who took tons of his money and left for some other guy who had more money
[18:15:10] <Jymmm> uw: Did you hear of the one that was dating the married 54yo guy, he got divorced, married the mistress, didn't want any more kids, so the new wife decided on her own that she wasn't going to take to BC and 9months later... BAM!
[18:15:57] <uw> wow Jymmm
[18:16:39] <Jymmm> uw: Fucked up huh
[18:17:19] <Jymmm> uw: Actually I think he was a bit youger, but not by much.
[18:17:23] <Jymmm> younger*
[18:17:24] <PetefromTn> How did we go from bulldozers to trophy wives to Gold digger wives...?
[18:17:41] <Jymmm> PetefromTn: JT-Shop wouldn't say how much =)
[18:17:48] <PetefromTn> aah..
[18:18:03] <Tom_itx> may as well go full circle... a D10 went for 100 oz of gold up in Alaska
[18:18:05] <PetefromTn> Maybe he is ashamed of how much he paid..
[18:18:11] <uw> my friends wife was in over $100k in debt from nursing school and had 2 kids with him. then one day bitch left a note "were done" and had moved in with another guy who was making 10x a much. meanwile, that $100k debt, 50% was stuck with him and he's still paying for this bitch's college debt even after shes living with a rich dude
[18:18:59] <Tom_itx> or maybe he doens't want the mrs to know what he's really worth
[18:18:59] <CaptHindsight> marriage licenses should only last 10-20 years tops and if you want to renew that's fine :)
[18:19:21] <uw> yea messed up Jymmm
[18:19:24] <uw> common here in us
[18:19:42] <uw> i think in germany wifes are more faithful, but really i dont have a good sample size
[18:20:10] <cradek> did you hear the one about the couple who split up in a way that was fair for them both, and they're both currently stable and happy and still close friends?
[18:20:14] <Jymmm> uw: I"m in Calif, but the moral of the story is NEVER BELIEVE THE BITCH AND ALWAYS WEAR A CONDOM
[18:20:39] <PetefromTn> Jeez man bitter much?
[18:20:45] <Jymmm> cradek: Yeah, it happens you just dont hear about it too much
[18:20:46] <uw> cradek, yup, it's called a disney movie
[18:21:03] <CaptHindsight> next time just plan ahead
[18:21:06] <uw> Jymmm, oic pretty much though. that or get a good prenup
[18:21:07] <cradek> oh and also neither of them harbors any deep misogyny
[18:21:28] <Jymmm> uwe_: prenump wouldn't matter if you got her pregnant
[18:21:40] <PetefromTn> That would be pretty easy right up until you have kids I guess.
[18:22:36] <Jymmm> cradek: The main issues why that usually doens't work is the whole monogamy thing.. the "you are mine and nobody elses" attitude.
[18:23:19] <Jymmm> cradek: But if they're open minded and can see out of the box, and COMMUNICATE, it changes the dynamics
[18:23:36] <CaptHindsight> http://www.hermann-uwe.de/hardware/linux-on-a-t1000le-laptop-using-elks Is this still running?
[18:24:03] <Jymmm> PetefromTn: Nah, just seen an awful lot of horror divorce stories.
[18:24:21] <Jymmm> PetefromTn: Got NetFlix?
[18:24:44] <PetefromTn> sure why?
[18:25:40] <Jymmm> PetefromTn: Watch "What Maisie Knew (2013)", it's a good movie, but you'll see what I mean =)
[18:26:50] <Jymmm> PetefromTn: It's on streaming btw
[18:27:09] <PetefromTn> Oh I don't need to watch any more movies to see what a bad divorce looks like. Honestly I think that when kids are involved it is nearly impossible to have anthing remotely amicable. It is just too hard to let go without anger issues. Never been thru it thank God but I have seen it before.
[18:27:49] <uw> thats true i feel so bad for the kids of the guy i nkow
[18:27:52] <Jymmm> PetefromTn: Oh no, you GOTTA see this... PSYCHO BITCH FROM HELL AND BACK
[18:28:07] <uw> everyweek it's half his out half the bitch's out
[18:28:08] <uw> house
[18:28:14] <PetefromTn> I feel like I am pretty damn lucky. I have a BEAUTIFUL wife who takes good care of me and we have kids and we get along pretty well. We do argue and fight occasionally but luckily it never gets too bad.
[18:28:53] <Tom_itx> good we go into it blind or we may become extinct
[18:29:12] <PetefromTn> I cannot imagine being with anyone else really and she puts up with all my crazy CNC and airgun and four wheeling bullshit so its all good LOL.
[18:29:25] <kengu> http://www.ustream.tv/channel/euromajdan
[18:29:26] <Jymmm> uw: BTW, that guy I was talking about? The kids are now 18+ and guess what he just went thru?
[18:29:43] <uw> Tom_itx, ever see the movie "idiocracy"
[18:29:52] <uw> i dont think we'll have a problem with going extinct LOL
[18:30:07] <Jymmm> uw: Surprisingly though, it was completely amicable.
[18:30:32] <uw> Jymmm, unbelievable, messed up indeed
[18:30:35] <PetefromTn> SOOOoooo anyone making anything cool with LinuxCNC today??!!
[18:31:03] <uw> i'm pricing out ballscrews...
[18:31:11] <uw> so i'm "bench making"
[18:31:19] <Jymmm> uw: Yeah, when she said she wanted a divorce, she want him to move out, he said no unless you are goign to buy me out right now (good for him)
[18:32:16] <uw> nice. these crazy bitches man, prolly the flouride LOL
[18:32:31] <Jymmm> uw: It gets even stranger... the divorce is final. He's moving out, into her parents empty rental house of all things.
[18:33:04] <uw> sitcom material LOL
[18:33:17] <Jymmm> uwe_: HBO/SHO special
[18:38:06] <PetefromTn> My wife just made me some Home made fajitas and black bean soup. It is SOOOOooo good!
[18:39:47] <kengu> they have a ~war in ukraine
[18:40:19] <Jymmm> ???
[18:41:08] <kengu> the euromajdan i posted earlier
[18:41:24] <kengu> and http://edition.cnn.com/2014/01/22/world/europe/ukraine-protests/index.html
[18:42:41] <kengu> at least one guy told me that he will not be dealing with a software issue as there is a revolution going on. "might take some time, like a lot of time to deal with that as we have a revolution going on" or likes
[18:49:58] <micges> kengu: all is heading to civil war and/or split up
[18:58:31] <skunkworks> micges: way too close to you...
[19:02:15] <micges> yeah, I'm little worried
[19:04:11] <skunkworks> I don't know what - but if there is anything we can do.. Let us know...
[19:05:46] <micges> it's not so bad, we are next when our finances will collaps
[19:05:59] <micges> maybe year or so
[19:12:59] <skunkworks> yeck
[19:18:53] <R2E4_> Hi all.
[19:20:12] <R2E4_> I have a mpg from cnc4pc mpg2, it has 4 wire quadrature A+ A- B+ B-,5vdc, Can I connect this to encoder port on the 7i77?
[19:20:49] <Tom_itx> should be able to
[19:21:40] <R2E4_> I see in the integrators m,anual they use one but with a card C22 going to parrelell port.
[19:23:32] <Tom_itx> what's field power on the 7i77?
[19:23:39] <uw> for ballscrews, whats the difference between the last 2 numbers?
[19:23:41] <R2E4_> 12vdc
[19:23:50] <Tom_itx> on the inputs?
[19:23:50] <uw> say for 2505 and 2510
[19:24:00] <Tom_itx> you need 5v for the mpg
[19:24:01] <uw> is that thread rate or threads per mm?
[19:24:09] <DaViruz> thread pitch
[19:24:27] <DaViruz> 5 or 10mm travel per revolution
[19:24:49] <uw> oh gotcha
[19:24:55] <uw> so lower = finer
[19:24:59] <R2E4_> I can supplyt 5 volts to the mpg, I just dont know if the 7i77 will sense it. it says 50% of voltage\
[19:25:04] <DaViruz> yep
[19:25:09] <uw> thank you DaViruz
[19:29:03] <R2E4_> I'll go with my other mpg thats 12v which I know works as I had it connected. It has momentary pushbuttonms and lites. I had the logic working for mux4 but it would take twice as many inputs and outputs, so maybe I will change the controls and use the rotary switches on the cnc4pc one.
[19:29:59] <Tom_itx> it says it can sense 5 to 32v but i presume that's based on the field voltage
[19:30:19] <Tom_itx> does it have a split field voltage?
[19:30:25] <Tom_itx> the 7i84 does
[19:30:30] <cradek> it's totally normal to have 5v encoder signals
[19:30:57] <Tom_itx> even with higher field voltages?
[19:31:18] <R2E4_> yeah, nost of the servo encoders are 5 volts....no?
[19:31:31] <Tom_itx> since it's input, i'd say try it
[19:31:44] <Tom_itx> if it were output to a 5v device i'd be reluctant to say that
[19:32:03] <Tom_itx> make sure you have a common ground to the MPG
[19:32:52] <R2E4_> The 5v common gnd to the 12vcommon ground..... ok
[19:33:29] <Tom_itx> i used single ended input to my 7i47 for one
[19:34:11] <R2E4_> my 12 one is a single ended input one and it connects directly to pins 16 and 17 in onthe 78i77, and it worked....
[19:34:32] <Tom_itx> i think i recall that discussion
[19:35:05] <micges> R2E4_: if you enable mpg input on 7i77 it will sense 5V regardless of field voltage
[19:35:36] <Tom_itx> that would be a nice additon to the docs somewhere
[19:35:51] <micges> it is in docs
[19:35:58] <Tom_itx> oh
[19:36:07] <Tom_itx> which ones?
[19:36:14] <Tom_itx> i don't recall running across it
[19:36:21] <micges> hold on
[19:36:27] <R2E4_> I have to connect it to the encoder inputs this one.
[19:36:38] <Tom_itx> but i don't have a 7i77 either
[19:37:02] <Tom_itx> i just split the field on the 7i84 and used half at 5v
[19:37:24] <R2E4_> the 7i77 docs doesnt mention that
[19:37:35] <micges> http://mesanet.com/pdf/parallel/7i77man.pdf
[19:37:45] <micges> first section of page 18
[19:38:12] <Tom_itx> probably why i missed it... i don't have one
[19:38:19] <R2E4_> I printed that manual
[19:39:12] <R2E4_> haha, I'm laughing.
[19:40:05] <R2E4_> It'll take mea whiole tofigure outhow to connect it and program it....lol, thanks micges
[19:41:57] <Valen> heres a question, I need to mill a bunch of glass
[19:42:01] <micges> welcome
[19:42:07] <Valen> I have used diamond burrs in the past
[19:42:16] <Valen> but they snap after a short while
[19:42:34] <R2E4_> mode 3,,,,,cool!JT helped me get mode 3 on it so thats what I'll be workinmg on.
[19:42:34] <Valen> (not pushing hard, i think they have stainless shafts that work harden and fatigue)
[19:43:06] <Valen> So i was wondering, can you get a diamond coated tool that uses carbide as the backing or am i better off with something else?
[19:43:59] <Tom_itx> micges thanks for pointing that out.. it's also in the 7i84 manual
[19:44:19] <Tom_itx> mode3 mpg thresholds set to 2.5v automatically...
[19:45:14] <micges> same for 7i76
[19:47:08] <R2E4_> I have a 7i84 but will run oput of outputs. I should have bopught the 8 channel rs422 boards then I can put many 7i84's.
[19:48:48] <Tom_itx> 7i71
[19:49:41] <Tom_itx> i was looking for inputs as well
[19:51:54] <micges> I had one machine with 96 outputs and 60 inputs, there was many 7i84 and 7i71 used
[19:52:16] <micges> all worked great, just plug and wire
[19:52:24] <Tom_itx> no timing problems?
[19:52:48] <micges> no
[19:53:07] <Tom_itx> i suppose most io like that isn't timing critical like some things
[19:54:58] <Tom_itx> nice thing about that is you can put them where you want so the wiring is shorter
[19:55:57] <micges> yes
[19:56:34] <micges> just get good shielded cables for them
[23:19:27] <t12> ,
