[00:35:20] <Connor> skunkworks: It was ME who told him his freaking IP was blocked. :)
[00:49:43] <WalterN> L84Supper: poke
[02:15:39] <gammax> there a root password for linuxcnc?
[02:23:10] <archivist> the password you gave when you installed, but no need normally
[02:23:32] <archivist> sudo su root
[02:24:15] <archivist> whatever you normally need to do can be done via sudo
[05:20:10] <UncleG> cradek my issue was solved with a simple WRAPPED_ROTARY = 1 inserted. Thank you.

[07:30:52] <Loetmichel> moin
[07:30:57] <Loetmichel> ahem mornin'
[08:41:59] <Loetmichel> ouch, THAT mill bit is done for... happens when the 4,0mm aluminium sheet detaches from the sacrificial plate at last cut... :-( bad: that was the last one :-( -> http://www.cyrom.org/palbum/main.php?g2_itemId=14190
[10:25:40] <cheesepuff> oh why you down support forums...
[10:55:17] <PetefromTn> ...
[10:55:33] <PetefromTn> Hello all...
[10:55:37] <Connor> PetefromTn: You get the flood cleaned up ?
[10:55:41] <carper64_lb> hi pete
[10:55:51] <PetefromTn> LOL yeah man what a beotch!!
[10:56:28] <PetefromTn> amazing how wide a spill ten gallons of coolant can make....
[10:56:42] <PetefromTn> carper64_lb: hi!
[10:58:10] <carper64_lb> was that raw coolant or mixed
[10:58:44] <PetefromTn> mixed in the trough, I was filling it for the first time and APPARENTLY it does have a small leak LOL
[10:58:58] <carper64_lb> hehehe
[10:59:39] <Connor> PetefromTn: You cable to save any of it ?
[10:59:41] <carper64_lb> gonna say if it was raw id be down on my knees suckng it up with a drinking straw at the price they charge for it lol
[11:00:02] <PetefromTn> carper64_lb: ROFL I hear ya man....!!
[11:01:06] <PetefromTn> Connor: Yup managed to get MOST of it out of the sump before it leaked out all onto the floor. Must be a very small leak because it took awhile for it to start showing then it started to flow pretty good. Right now I have a blue water bathtub ....
[11:21:00] <carper64_lb> well its one of the days
[11:24:04] <carper64_lb> been putting off finishing the lathe for a while cos i hate the software side of the build decided to do some today and linuxcnc is broken just sent chris the errors and screenshots iam gettng
[11:26:08] <carper64_lb> been a big build heres some pic looks nothinglike an orac now https://www.dropbox.com/sh/6mcv3ywgf1cefrh/fnSNBgcdQH
[11:29:32] <carper64_lb> next project is an denford easimill with 4th and 5th axis
[11:33:50] <PetefromTn> Well felllas I gotta head to the store and buy some kidna hand pump or something to drain my bathtub of the coolant after I tig weld up the leaks in the tanks....Oh well I guess it could be worse right. LOL
[11:33:56] <PetefromTn> Signing out...
[11:56:46] <generic_nick> hi
[11:57:23] <generic_nick> having some machine issues, wondering if i could run some things by you guys.
[11:57:34] <jdh> are they generic issues?
[11:57:41] <generic_nick> i wish
[11:58:19] <generic_nick> i have a 3 axis mill, emc2, all mesa hardware, servo driven
[11:59:43] <generic_nick> 5i20, 7i33 servo card
[12:00:23] <skunkworks> cool
[12:00:29] <generic_nick> i have 3 pacific scientific digital servo drives, and 3 pacific scientific brushless servos with resolvers on them that feed back to the drives
[12:00:53] <generic_nick> worked fine for years.... now im having issues with all 3 drives
[12:02:16] <archivist> electrical noise, check grounding
[12:02:24] <generic_nick> first the x axis had to be slowed down from 300ipm rapids to about 200ipm, or it ferrored. then the z axis stopped working. i got the z axis working again by swapping in a spare drive, now the y axis died
[12:03:32] <generic_nick> it seems that i have 2 dead drives and the y axis motor is done
[12:04:15] <generic_nick> archivist: thanks, ill check that.
[12:04:55] <skunkworks> struck by lightening?
[12:04:59] <generic_nick> i swapped the y axis motor to the z axis drive that is known to work now and the motor is done
[12:05:10] <generic_nick> skunkworks: not where i live lol
[12:05:15] <skunkworks> heh
[12:05:15] <archivist> after a long time to me means cable and other connection failures
[12:05:46] <generic_nick> archivist: i have recently upped the max velocity
[12:05:59] <generic_nick> wondering if that cooked some stuff
[12:06:03] <cradek> sometimes by swapping parts around you can destroy all of them
[12:06:15] <generic_nick> cradek: thats what im afraid of
[12:07:18] <largecheesepuff> really wish I could figure this out..
[12:07:23] <IchGuckLive> hi all B)
[12:07:24] <archivist> shorted turns on a motor killing a drive, then you move another drive to that motor.....
[12:10:31] <generic_nick> guess i could check impedence on the motor, huh?
[12:10:40] <generic_nick> see if it differs from the others?
[12:12:02] <andypugh> Sounds like a good plan. Does it make any torque at all?
[12:12:22] <andypugh> Check the resolver too.
[12:12:25] <generic_nick> no
[12:12:32] <generic_nick> i did, feedback is fine
[12:12:51] <andypugh> Ah, no torque at all probably means a broken winding, or cable.
[12:13:19] <generic_nick> when i swapped drives this morning, it had a tiny bit of holding torque
[12:13:29] <generic_nick> now nothing
[12:13:31] <andypugh> Locking solid and not rotating could be a broken (or just loose on the shaft) resolver.
[12:14:09] <generic_nick> i can rotate the ballscrew and the counts seem fine
[12:14:44] <andypugh> Checking the windings (and the cable) seems like the next step.
[12:15:09] <generic_nick> yea im going to go check that out. some coolant has been known to leak on that motor
[12:15:40] <generic_nick> ill see if i can pop the end off to check out the wiring on the motor
[12:15:50] <andypugh> Brushless motors + resolvers should work underwater though.
[12:17:51] <generic_nick> one would think
[12:18:45] <generic_nick> my buddy has a brick of glentec drives i may swap in with some old glentec servos i have kicking around
[12:19:06] <generic_nick> id just rather not do more work than i have to
[12:29:17] <generic_nick> no resistance at the motor
[12:29:28] <generic_nick> at at least from the harness
[12:29:42] <generic_nick> gunna pull the end off the motor and check it there
[12:32:56] <archivist> no resistance, meaning dead short or open or what
[12:33:27] <archivist> what does a good one measure
[12:34:19] <Loetmichel> archivist: dead short cant be, the usual motor wires have still a little resistance ;-)
[12:35:55] <archivist> define little
[12:36:28] <Loetmichel> in the 0.2-0.5 ohms range ;-)
[12:36:30] <archivist> some people do not have suitable meters for low resistance measurement
[12:36:37] <Loetmichel> ... definetly not short ;-)
[12:36:55] <archivist> Loetmichel, why are you trying to teach me :)
[12:37:24] <Loetmichel> not teaching, just wanted to make a joke. gone wrong i assume? ;)
[12:41:55] * Tecan stop drop and rofl
[12:45:59] <generic_nick> it was open
[12:46:40] <generic_nick> but i checked it at the motor and it is 0 ohms to all 3 wires. seems like the connector might be bad
[12:46:53] <generic_nick> weird
[12:48:37] <cpresser> 0 Ohms is not open. Unlimited Ohms is open
[12:48:53] <generic_nick> i am aware of that. it was open.
[12:48:58] <cpresser> ah stop, i didnt read correctly
[12:49:05] <cpresser> it was open at the connector
[12:49:09] <generic_nick> yes
[12:49:17] <cpresser> sorry. my bad
[12:49:32] <generic_nick> no worries.
[12:49:48] <generic_nick> my meter is a cheapo, so im sure it isnt exactly 0 ohns at the motor
[12:50:00] <generic_nick> but there is continuity.
[12:50:57] <Loetmichel> could also be broken wires when the cabling is a bit old and the maschine is used much
[12:53:04] <generic_nick> i believe it is an issue caused by coolant leaking down the cable into the connector in the middle of the cable
[12:53:33] <generic_nick> it's a water tight AMP connector, but coolant eats at the rubber
[12:58:36] <generic_nick> found a broken wire in the connector
[12:58:59] <generic_nick> still not sure if the drive is good though
[12:59:31] <generic_nick> bbiab, gunna repair the connector
[14:01:22] <andypugh> The suspense!
[14:05:25] <skunkworks> andypugh, in a better mood?
[14:06:34] <andypugh> Yeah, I spent a lot of money and parts are on the way.
[14:06:55] <skunkworks> that works
[14:06:57] <archivist> a new exhaust?
[14:07:28] <andypugh> No, but I think I can drop it far enough out of the way
[14:07:44] <andypugh> A second hand alternator (£300)
[14:08:23] <archivist> a bit pricey
[14:13:52] <andypugh> Yes, but cheaper than new, for that price I get add up to £992 new-price.
[14:15:11] <andypugh> I wonder what it would cost to assemble a complete bike from spares?
[14:16:39] <archivist> about 3 times the new price probably
[14:18:45] <andypugh> Far worse than that, I think.
[14:48:00] <generic_nick> so the drives are shot.
[14:48:36] <generic_nick> im putting on my dc brushed glentek servos
[14:48:47] <generic_nick> sucks....
[14:49:54] <generic_nick> anyone in here use copley servo drives? i'm about to install some
[14:57:50] <DJ9DJ> namd
[15:04:01] <andypugh> Ah, he went. I was going to suggest that he could use the Mesa stuff to drive his resolver servos.
[15:10:44] <L84Supper> anyone know of an editor to make small changes to Parasolid files? besides importing to NX, Solidworks or Catia...
[15:37:25] <Tom_itx> not familiar with parasolid
[15:40:53] <Tom_itx> what is Navisworks?
[15:41:04] <Tom_itx> http://docs.autodesk.com/NAVMAN/10.0/ENU/Autodesk%20Navisworks%20Manage%202013%20Online%20Help/index.html?url=files/GUID-05D79766-4E60-4381-BBA3-1658EEAF36B1.htm,topicNumber=d30e85927
[15:45:48] <L84Supper> never even heard of that^^
[15:46:03] <Tom_itx> seems it may be encrypted
[15:46:12] <Tom_itx> http://www.emastercam.com/board/index.php?showtopic=66831
[15:46:24] <L84Supper> i was just wondering if there was something similar to a Gerber editor for parasolid
[15:46:46] <Tom_itx> http://www.cadlook.com/
[15:46:48] <Tom_itx> ?
[15:46:51] <Tom_itx> no idea
[15:48:31] <L84Supper> it's only sheet metal, I have spent more time looking into howto's for editing than it would have taken to just redraw them :)
[15:48:40] <Tom_itx> haha
[15:48:48] <Tom_itx> been there.
[15:48:57] <Tom_itx> just irks me sometimes
[15:49:20] <Tom_itx> gotta run..
[15:50:02] <Loetmichel> L84Supper: been there, too
[15:51:02] <MattyMatt> sod's law says you'll remember what you learned until the week before you need it again
[15:51:03] <Loetmichel> just finished some sheet metal work... and it fits in just 2 trys... it seems i get better and better in designing seet metal constructions ... with coreldraw8 ;-)
[15:51:16] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14184
[15:51:25] <MattyMatt> I still do everything in blender. it's sick I know
[15:57:17] <DJ9DJ> gn8
[16:10:12] <generic_nick> andypugh: were you talking about me?
[16:10:35] <generic_nick> didnt know mesa made servo amps
[16:16:13] <generic_nick> PCW: can i pick your brain for a bit on the mesa servo drives?
[16:28:50] <andypugh> generic_nick: Aye, I was.
[16:29:51] <andypugh> I am using the Mesa 8i20 and 7i49 combination. However a full conversion is likely to cost more than replacing just your failed amp.
[16:41:41] <PCW> andypugh freeby.mesanet.com/sserial.zip
[16:42:12] <PCW> new firmware for 7i73 etc
[16:42:24] <andypugh> OK, what does it add?
[16:42:39] <PCW> it subtracts bugs
[16:43:43] <PCW> (and 7I73 modes database is re-organized to make more sense in dmesg list)
[16:44:18] <andypugh> Jolly good.
[16:46:34] <PCW> 7I73 2 key rollover bug fix as well
[16:46:53] <PCW> Would like a stern warning to upgrade sserial remote firmware if swrevision is <14 added to master
[16:48:44] <PCW> (applies only to generic, not 8I20 or 7I64)
[16:54:17] <PetefromTn> Hey guys, I dunno if you have read of my coolant adventure today. Lots of fun. Well I managed to drain the tank out and have removed them, they are sitting in the driveway now. I found quite a bunch of little rust pin holes in the bottom of the tanks and one or two that were most likely the cause of the leak. Looking for suggestions about how to repair this so it never leaks again. I am gonna tig weld up the larger holes
[16:54:17] <PetefromTn> but there are so many tiny pits that is impossible to weld on them all...
[16:59:44] <L84Supper> PetefromTn: is the bottom flat or?
[17:00:18] <PetefromTn> Yeah the bottom is flat but it has partitions in it where the pump is isolated behind a chip screen on the left side one.
[17:01:05] <L84Supper> cut out the cancer and weld new metal or try to seal it up in epoxy
[17:02:42] <MattyMatt> plumber's solder?
[17:02:42] <andypugh> Line it with epoxy and glass fibre?
[17:02:48] <PetefromTn> Yeah I am gonna try to weld it up but again there are tiny pin holes everywhere on the bottom. I dunno if I can get them all....
[17:03:31] <MattyMatt> solder will fill small holes, and preserve the thin metal awhile
[17:03:36] <andypugh> http://www.mandp.co.uk/productinfo/501102/Workshop/Workshop-others/Petseal/Ultra-Tank-Sealant
[17:03:50] <PetefromTn> I am considering taking it down and having them sandblasted on the bottoms and then weld up the problem areas and line it with some kinda sealant..
[17:04:04] <L84Supper> $35/gal polyester resin at home depot, mix and brush on
[17:04:51] <PetefromTn> Will the resin stick okay to the tanks insides? Will it make it rust more from condensation?
[17:04:52] <L84Supper> http://www.homedepot.com/p/Home-Solutions-1-Gallon-All-Purpose-Fiberglass-Resin-20124/202077791
[17:05:05] * JT-Shop thinks of the screen door in the boat ad
[17:05:44] <L84Supper> a gallon is enough to coat your tank a few times over
[17:05:48] <MattyMatt> full fibreglass lining will mean it doesn't matter if it rusts more
[17:06:06] <PetefromTn> This E206 trim sol coolant is known to be tough on certain sealants and chemicals...
[17:06:43] <L84Supper> the polyester resin polymerizes, not much breaks it down
[17:06:46] <PetefromTn> Well fiberglass lining is not gonna happen LOL... epoxy lining maye
[17:07:06] <MattyMatt> hot dip zinc is how I'd do it, if I had a giant vat of molten zinc handy
[17:08:02] <PetefromTn> I could maybe cut off the bottom plate and get some sheetmetal and tig weld a new one on but that would take awhile and I would STILL have to seal it from rusting somehow..
[17:08:05] <L84Supper> use the current tub as a mold, recast it in aluminum
[17:08:38] <PetefromTn> Seriously guys I need some tried and true options here...
[17:09:07] <L84Supper> once the iron rusts you have to cut it out
[17:09:30] <MattyMatt> hemp & tar
[17:09:45] <L84Supper> the rust coatings might seal it but any moisture will just get it rusting more
[17:10:01] <andypugh> If it was my tank then fibreglass would be the way I did it.
[17:10:06] <L84Supper> it's the same for auto bodies and gas tanks
[17:10:25] <L84Supper> what works for automotive?
[17:10:28] <MattyMatt> would coolant dissolve bitumen?
[17:10:48] <andypugh> MattyMatt: I think so.
[17:10:59] <andypugh> Gutta-Percah might work :-)
[17:11:30] <L84Supper> change over to water free coolant
[17:12:19] <L84Supper> PetefromTn: have a pic of the tub?
[17:12:31] <MattyMatt> is tig welding thin sheet easier than brazing?
[17:12:45] <JT-Shop> get new tanks fabricated from stainless steel
[17:13:06] <PetefromTn> Do you guys think that welding the holes up good after a sand blasting and then powder coating would keep it from leaking again.
[17:13:19] <PetefromTn> I tig weld thin sheet all the time..
[17:13:30] <L84Supper> if you get all and I mean all the rust off
[17:13:33] <PetefromTn> Stainless tanks would be sweet but probably cost a small fortune...
[17:13:34] <JT-Shop> sounds like more work that replacing the tank
[17:13:44] <JT-Shop> than
[17:13:47] <L84Supper> the powdercoat will be just like the polyester resin
[17:13:51] <JT-Shop> how big is the tank?
[17:14:41] <PetefromTn> Dunno, it is about eight or nine feet long, about a foot and a half wide, and about a foot deep maybe fifteen inches. The other side one is only about six feet long but the same width and height.
[17:14:44] * JT-Shop assumes that if it rusted enough to have pin holes all over then there ain't much left of the base metal... but I can't see from here
[17:15:05] <PetefromTn> I can take a picture but not sure how to let you all see it...
[17:15:06] <L84Supper> all powder coating is are polymers ground to few micron size particles that you melt into a smooth-ish surface
[17:15:13] <JT-Shop> get a sheetmetal shop to break the U and weld on the ends
[17:15:20] <cradek> weld an entire new bottom over the old one?
[17:15:35] <cradek> there's no use trying to fix something that's rusted away
[17:15:48] <JT-Shop> exactly
[17:15:59] <PetefromTn> cradek: I have considered that actually. The only concern is that it is not just a flat bottom bucket kinda thing there is a partition in there too...
[17:16:04] <JT-Shop> PetefromTn: imagebin.org
[17:16:23] <generic_nick> andypugh: i cant get my drives anymore. and i need it running asap.
[17:17:00] <generic_nick> PCW: do you have anything to run an 11 amp dc brushed motor?
[17:18:25] <andypugh> 7i29 might work, 22.5A 165V, $300 (drives 2 motors)
[17:18:27] <micges> generic_nick: see mesa 7I29
[17:19:53] <andypugh> generic_nick: Or http://pico-systems.com/osc2.5/catalog/product_info.php?products_id=26
[17:20:21] <andypugh> What other hardware do you have? How are you controlling the existing amps?
[17:20:25] <generic_nick> thanks guys
[17:20:54] <PetefromTn> Okay I'll snap some pictures of them and the damage....
[17:21:05] <generic_nick> 5i20 and 7i33
[17:21:44] <generic_nick> ouch, 600 for 2.
[17:22:11] <GammaX> aftgernoon all
[17:22:38] <generic_nick> andypugh: the pico one might be a better option since i only need 1 or 2 right now
[17:22:45] <generic_nick> and money is tight
[17:22:57] <GammaX> Im having some issues installing pci-e parrallel port into my system.... Cant get drives to install...
[17:24:02] <andypugh> generic_nick: The 7i29 will plug directly into the 5i20. You can have 4 motors per 5i20 header (2 7i29s)
[17:24:21] <andypugh> GammaX: You shouldn't need any drivers.
[17:24:24] <generic_nick> yea, i just cant swing $600 right now
[17:24:43] <andypugh> generic_nick: If you need two motors, that's 1 7i29.
[17:24:46] <GammaX> andypugh, how can I determine if it is recognized...
[17:24:49] <generic_nick> do you have them in stock?
[17:25:03] <generic_nick> PCW: right, but i still need the 7i33
[17:25:14] <generic_nick> and im out of headers on the 5i20
[17:25:20] <andypugh> Ah.
[17:25:37] <micges> see 5i22
[17:25:42] <micges> 4 headers
[17:25:51] <andypugh> And rather spendy..
[17:25:53] <generic_nick> yea but again, too much money
[17:26:11] <generic_nick> id be better off with just getting 2 7i29's
[17:27:30] <GammaX> andypugh, any thoughts?
[17:28:14] <andypugh> GammaX: Plug it in, then try lspci
[17:28:50] <andypugh> generic_nick: http://www.ebay.com/sch/i.html?_odkw=AMC+servo&_osacat=0&_from=R40&LH_PrefLoc=1&_trksid=p2045573.m570.l1313.TR0.TRC0&_nkw=AMC+servo+-brushless&_sacat=0
[17:36:02] <JT-Shop> I think I had a better connection with a 1200 baud modem than satillite in the rain
[17:40:42] <generic_nick> thanks andypugh. i did look on ebay
[17:41:12] <L84Supper> satellite TV has been up, we were having problems with WiMAX earlier
[17:41:34] <andypugh> generic_nick: Ah, OK, nothing suitable?
[17:41:51] <andypugh> Anyway, I need to log off now.
[17:41:54] <L84Supper> JT-Shop: what kind of upload speed do you see with your service?
[17:42:04] <JT-Shop> been raining all day here with some tornados (small ones) this afternoon
[17:42:16] <JT-Shop> I've not checked
[17:43:07] <JT-Shop> speedtest might not even load lets see
[17:45:14] <JT-Shop> pin 845ms
[17:45:15] <JT-Shop> ping
[17:45:15] <JT-Shop> download 3.77Mbps
[17:45:21] <JT-Shop> upload failed
[17:46:59] <JT-Shop> someone is running fiber up the road at the highway, I hope it has internet
[17:47:00] <JT-Shop> actually many roads around here are getting new fiber installed
[17:50:53] <L84Supper> we just got cable here, AT&T had fiber here, but didn't want to offer anything less than 10/10mb for $1200/mo.
[17:52:54] <PetefromTn> pics of rust and stuff...http://s150.photobucket.com/user/matospeter/library/cnc%20stuff?sort=3&page=1
[17:53:51] <JT-Shop> hmm the link doesn't work
[17:54:58] <GammaX-2> well the card is now installed according to ubuntu
[17:55:07] <GammaX-2> just need to be able to find its address...
[17:55:19] <JT-Shop> which card?
[17:55:27] <PetefromTn> http://s150.photobucket.com/user/matospeter/library/Cincinatti%20Arrow%20500%20Retrofit?sort=3&page=1
[17:55:39] <GammaX-2> combo parallel serial card
[17:56:03] <JT-Shop> that one worked... now if I can download it
[17:56:08] <JT-Shop> lspci
[17:56:14] <JT-Shop> or maybe lspci -v
[17:56:50] <GammaX-2> yeah I tried that...
[17:56:52] <L84Supper> the bottom is flat
[17:57:02] <PetefromTn> L84Supper: are you talking to me?
[17:57:43] <L84Supper> PetefromTn: yeah, is it flat?
[17:58:04] <PetefromTn> yup it's flat but as you can see on the one with the partition it is not that simple...
[17:58:39] <PetefromTn> Also the pictures make the rust look a lot worse than it is, a lot of that is really just light surface rust but the closeup shows the real damage...
[17:59:24] <GammaX-2> PetefromTn, electrolosys!
[18:00:28] <PetefromTn> Dunno really what to do right now. Sucks...
[18:00:45] <GammaX-2> PetefromTn, what do you mean?
[18:01:00] <L84Supper> the most permanent fix is to cut the bottom out a weld in a new one
[18:01:48] <PetefromTn> huh? I mean I don't know what to do with it, it is really a beotch and I am not happy about it. I suppose welding in a new bottom is the most obvious permanent solution. Cutting out the bottom will be a real pain tho...
[18:02:11] <L84Supper> http://www.por15.com/faq.asp is another option and epoxy painting
[18:02:46] <L84Supper> body filler/bondo is also a cheap fix
[18:03:06] <GammaX-2> you can prolly use that entire tub as part of the electrolysis thing... hook the negative side to the container... and dangle a steel rod the length of the thing ( rebar) and attach the positive to it... 10 amps and 12v it will be rand new by morning
[18:03:55] <L84Supper> he has too many holes for that to work
[18:04:15] <PetefromTn> Yeah I was considering POR15 but it would probably take 2 gallons or more and I am not sure of the coolant acting on it...
[18:04:51] <GammaX-2> rust holes?
[18:05:11] <L84Supper> yeah, lots of pinholes
[18:05:15] <GammaX-2> ouch...
[18:05:22] <PetefromTn> Freakin guy I bought it from left it sitting with bad coolant in it for the year or more that it sat idle with clumped up chip brownies in the bottom and a layer of rusty coolant. I'd like to kick his ass right now....
[18:05:44] <GammaX-2> how thick?
[18:05:47] <GammaX-2> steel or alum?
[18:06:14] <PetefromTn> It is actually quite thick sheetmetal the whole thing is made from and it is of course steel.
[18:06:41] <JT-Shop> like 11 gauge
[18:07:17] <PetefromTn> Dunno the gauge but I can check tomorrow. It is self supporting tho even without the bends.
[18:07:48] <GammaX-2> id follow suite with L84Supper and cut it out.... install new one.... that or wire brush the shit out of it on an angle grinder and and oxy acetaline weld the pin holes... prolly wond even need wire for that..
[18:08:49] <PetefromTn> I would just tig weld the holes if I thought I could get them all. Cutting out the bottoms is looking more and more like my only real option. It would actually probably be cheaper than having it blasted and powdercoated.
[18:10:05] <PetefromTn> Why do people pay an arm and a leg for a machine tool and then neglect the things that make it work like that.... You should have seen all the crud and dried on chips on this monster I have had to clean up. It is not like it is hard to do really.
[18:11:57] <PetefromTn> What about welding it up and then using some garage floor sealant on the inside?
[18:17:22] <GammaX-2> aslong as the coolant your using wont erode it...
[18:30:16] <JT-Shop> PetefromTn: how thick is the metal?
[18:31:26] <JT-Shop> GammaX: http://www.linuxcnc.org/docs/html/examples/pci_parallel_port.html
[18:33:11] <JT-Shop> GammaX: what was that the output from?
[18:35:24] <GammaX-2> lspci -v
[18:35:41] <GammaX-2> it has 2 serial ports and a parrallel port on it...
[18:36:42] <GammaX-2> JT-Shop, ^^ sorry didnt tag you.
[18:38:53] <JT-Shop> so you didn't see a PCI port parallel adaper in the output?
[18:39:14] <JT-Shop> like is shown in the link I gave you...
[18:39:37] <JT-Shop> I'm in and out of the shop
[18:39:41] <GammaX-2> nope, only that serial controller...
[18:40:16] <JT-Shop> WAG you might unplug the serial controller and run lspci -v again
[18:40:47] <GammaX-2> well that serial controller IS the parallel port aswell...
[18:40:53] <GammaX-2> 3 ports... one card...
[18:41:43] <PetefromTn> Okay I just set one of them up on sawhorses and hit it with my pneumatic drill/wire cup wheel in the bottom of the tray and it is basically screwed. I mean there are little pits and pockets everywhere... Just basically SOL here I guess. Gonna call tomorrow about some new sheetmetal for it and hope to be ale to cut out the base and tig weld in some new sheetmetal. Always has to be a real pain in the ass whenever I try to do
[18:41:44] <PetefromTn> something I guess...
[18:49:47] <tjb1> hi JT-Shop
[18:53:15] <JT-Shop> hi tjb1
[18:53:22] <tjb1> how ya doin
[18:53:48] <JT-Shop> PetefromTn: your not screwed, now you know the extent of the damage and have damage control in place
[18:54:07] <JT-Shop> having fun making machines and getting ready for SpyderFest!
[18:56:46] <GammaX-2> I think im screwed with this card as a parallel port...
[19:01:31] <PetefromTn> JT-Shop: Yeah I know but I bought this machine over a year ago and it has been a freakin' uphill battle all the way trying to get it to a place where I can finally use it to make some money. This is not a hobby for me here and while I enjoy working on it and doing the retrofit I am about over it and just want it to work now....
[19:01:42] <PetefromTn> I know poor me right....LOL
[19:02:05] <JT-Shop> no, I completly understand how you feel
[19:02:31] <JT-Shop> my VMC has given me fits for years but I just learned to work with it
[19:02:46] <JT-Shop> sometimes you just have to bite the bullet and replace parts...
[19:07:27] <JT-Shop> what kind of parts are you going to make?
[19:07:31] <PetefromTn> It has been a dream of mine to have a machine like this working in my shop so I can really start making parts for people and hopefully turn it into something that I can profit from for years to come along with my fabrication work but so far it has been one disappointment after another with this thing...
[19:10:19] <PetefromTn> I HAD a couple companies that wanted me to make some prototypes and several folks who wanted me to manufacture some small aluminum parts for awhile there along with some of the custom badging and other ideas of my own that I had made some small cash with but basically anything that walks thru the door and is a paying gig I woul be interested in. I just have to keep telling myself that I am almost there, I just gotta fix the
[19:10:20] <PetefromTn> last few issues with the machine and move onto making parts. This coolant problem is gonna be some considerable work and money tho atop a mountain of already spent considerable work and money.
[19:12:52] <JT-Shop> seems like you have been making good progress latley
[19:12:52] <JT-Shop> lately
[19:12:52] <JT-Shop> one finger typin cat has other hand
[19:14:35] <PetefromTn> Yeah things were starting to look up.....for awhile anyways. I am gonna just grab some cutoff wheels for my angle grinder and buy a sheet of steel and hit it tomorrow hard. Hopefully things will go well and I can shoot some epoxy paint on it and reinstall it over the weekend and be milling and testing by monday...
[19:15:43] <JT-Shop> you do know for steel you usually just use air with carbide tooling
[19:15:52] <JT-Shop> cool
[19:15:53] <JT-Shop> no fab shops near that can shear it to size?
[19:17:37] <Tom_itx> JT-Shop, do you cnc more aluminum or steel?
[19:17:44] <JT-Shop> 6061 mor3e than 1018
[19:20:35] <JT-Shop> say goodnight Gracie
[19:20:39] <Tom_itx> is carbide tooling more effective for you than hss?
[19:20:46] <PetefromTn> Actually my friend had a nice shop with a full complement of sheetmetal machinery press brakes etc. but they went out of business recently...
[19:20:54] <MattyMatt> if you're getting so much experience making your tools then maybe you should make them to sell
[19:21:08] <JT-Shop> insert tooling for 6061 is better for me the dead sharp ones
[19:21:40] * JT-Shop heads inside now
[19:21:41] <Tom_itx> just curious what happens outside an aircraft town
[19:21:55] <MattyMatt> a cnc slantbed the size of a sherline, that'd sell I bet
[19:22:19] <MattyMatt> with a turret, live tooling, bar feeder, auto chuck etc.
[19:23:51] <JT-Shop> too expensive for cheap hobbiest types
[19:23:56] <MattyMatt> I loved that pic of blddk's insert holders with built in coolant spray. they are as good an argument as any for carbide
[19:24:04] <MattyMatt> $250 per tho
[19:24:50] <MattyMatt> https://www.dropbox.com/s/3gl33vk0nzfwnrb/2013-04-18%2013.48.03.jpg
[19:25:14] <PetefromTn> nothing there...
[19:25:15] <MattyMatt> bah deleted pic
[19:25:50] <MattyMatt> 2 jets of coolant in the insert holder, that converged right at the tip
[19:26:01] <MattyMatt> right in the chipbreakers
[19:26:47] <PetefromTn> Honestly I do not understand the reasoning behind any machine the size of a sherline. Hell if I wanted a HOBBY machine I would want it to be at least the size of like a 9x20 or 11x26 or something.... at least it could make something useful for more than jewelry or RC cars...
[19:27:24] <MattyMatt> some people just want small stuff, and only have a bedroom etc to work in
[19:29:11] <MattyMatt> http://www.thecooltool.com/workshops.php?language=e
[19:29:26] <MattyMatt> or half a bedroom, if it's a big family :)
[19:30:14] <MattyMatt> pics confirm unimat 1 is a toy, although the cnc version looks neat
[19:34:59] <MattyMatt> http://www.thecooltool.com/produktgruppe.php?language=e&status=20&sh_id=75&ptitel=UNIMAT+CNC
[19:35:40] <MattyMatt> easier than cncing a lorch I bet
[19:39:59] <MattyMatt> they even supply a custom linuxemc cd with it :) CoolCNC Linux? is that ethical or a legit distro?
[19:40:36] <MattyMatt> they haven't renamed the program (it's called EMC2 in the manual(
[19:41:49] <largecheesepuff> So if you look at Hal Meter > Signals spindle-index-enable should you see the meter flips from false to true as you rotate the spindle?
[19:47:35] <Tom_itx> PetefromTn, what _would_ you recomend starting out as a hobbyist then?
[19:47:50] <Tom_itx> on say a 3k budget
[20:02:07] <L84Supper> Tom_itx: http://chicago.craigslist.org/nch/tls/3726077310.html and a $500 phase converted
[20:03:40] <Tom_itx> doubt that would fit my space
[20:04:21] <Tom_itx> gawd those tool holders are huge
[20:12:29] <PetefromTn> Tom_itx: I dunno really as a hobbyist things are much different. I will say this tho, I have owned everything from a 3 in 1 machine to an RF45 to a knee mill and now a VMC and having done two retrofits now I can honestly say that despite my recent issues with rusty coolant troughs it has been MUCH easier to retrofit a machine that was born a CNC machine than one that was born a manual machine. If I was looking to get into a
[20:12:30] <PetefromTn> hobby machine I would probably look to find a good condition used CNC like a boxford or a denford or something that is already a cnc and then upgrade the control and motors to newer stuff. No machining ballscrews, no fabricating mounts, no trying to reinvent the wheel. Some of these small machines even came equipped with toolchangers and stuff like that. They are also well made. My RF45 mill was really sweet and I made all
[20:12:30] <PetefromTn> sorts of stuff with it both before and after CNC but it took a full year to do the retrofit and it was A TON of work..
[20:13:18] <Tom_itx> i used to work in a large shop and now i play with a sherline
[20:13:36] <Tom_itx> so i've been on the extreme ends of it
[20:13:52] <PetefromTn> If you have some more space to work with a CNC bedmill would be sweet to retrofit and very capable...
[20:14:25] <Tom_itx> if i got something bigger it would need to be some sort of tabletop or prototype cnc
[20:14:36] <Tom_itx> i agree the sherline is pretty flimsy
[20:14:52] <Tom_itx> i've done quite a bit with it thru the years though
[20:15:27] <PetefromTn> That is exactly my problem with them... A lot of times my 12x36 lathe work makes me wish I had a much larger machine and I could chuck up the sherline lathe in it pretty easily...
[20:16:31] <Tom_itx> we had Tree, Fadal, Okuma and a couple others in the shop
[20:16:41] <Tom_itx> the Okuma are nice
[20:17:43] <PetefromTn> To be quite honest if I HAD to have a very small table top machine I would look to get a very nice CNC router table with around a foot of travel in each direction and get one beefy enough to machine aluminum. Then you can do some really cool stuff and have enough travel to enjoy it. There are some amazing little CNC routers available today and some are quite capable of machining aluminum.
[20:18:19] <PetefromTn> If I had not bought my Cincinatti Arrow 500 I was looking for a Fadal VMC. Fadals are nice machines and easy to maintain from most accounts.
[20:18:31] <Tom_itx> i'm not looking for a router
[20:18:40] <MattyMatt> denford had a dinky stepper driven toolpost
[20:19:07] <MattyMatt> that'd be easy enough to retrofit to any old lathe
[20:19:35] <Tom_itx> Fadal are lower end but they do well on aluminum
[20:19:50] <MattyMatt> I guess you could survive without a brake if it was worm drive
[20:19:58] <PetefromTn> Someone need to make a really heavy duty CNC router that is a largish table top model out of steel or cast iron that comes in at say 2-300 lbs and can cut steel a bit.... That would be a sweet machine. My pal Art made a nice aluminum one he calls the nightmare and he loves it.
[20:20:04] <MattyMatt> brake/dogclutch
[20:20:45] <PetefromTn> Huh? I have a friend local who has a Fadal 6030 and all he does with that machine is make steel moulds...makes some good money with it too. Damn fine machine....
[20:21:19] <Tom_itx> they're ok
[20:21:25] <PetefromTn> Most of the moulds he makes he needs to load the machine with a forklift!!
[20:21:27] <Tom_itx> they don't hold up as well as others
[20:21:41] <PetefromTn> That's absolutely not what I have heard....
[20:21:42] <Tom_itx> we had 2 pallet changers on one of the Okumas
[20:21:46] <Tom_itx> with dual toumbstones
[20:22:20] <PetefromTn> You're talking a $500k machine there....
[20:22:27] <Tom_itx> i know
[20:29:16] <Tom_itx> PetefromTn, their equipment list has changed a bit since my friend sold the place but some are still there: http://clearwateren.com/manufacturing.php
[20:30:47] <PetefromTn> Looks like a well equipped shop there... I would just like to have a decent working VMC to make custom parts. Maybe hopefully soon I will LOL
[20:31:08] <Tom_itx> yeah, he started in a 24 x 24 garage
[20:31:19] <Tom_itx> and i was there helping him from the beginning
[20:31:55] <PetefromTn> Hey my shop is 25x25 LOL....
[20:32:16] <PetefromTn> Check out this SWEET homebuilt recumbent Tadpole trike...http://www.youtube.com/watch?v=yw9gWlpdQoI
[20:32:17] <Tecan> (yw9gWlpdQoI) "Completed DIY Recumbent Warrior Trike" by "Spinner Guy" is "Autos" - Length: 0:00:53
[20:33:16] <L84Supper> the bot is back
[20:33:52] <Tom_itx> is that you in the video?
[20:35:11] <PetefromTn> Nope but I did build my own recumbent recently. I just spotted that one on youtube, it is an AtomicZombie model they recently came out with. You can download the plans for $17.00 or so and build it yourself. It is really a sweet machine and one like it manufactured costs several thousand dollars new..
[20:35:19] <PetefromTn> L84Supper: hhey bot.
[20:56:27] <GammaX-2> went to micro center and refused to spend 40 dollars on a parallel port card...
[20:56:49] <GammaX-2> Im either getting this one working or im im going back to amazon! lol
[20:57:22] <WalterN> L84Supper: well, I bought a power supply
[20:57:41] <WalterN> its not designed for diode lasers, but it is constant current
[20:57:51] <WalterN> it will work for testing things
[20:58:02] <WalterN> until I get a diode laser driver
[20:59:41] <GammaX-2> is the newest version of linux cnc on 2.4 or 2.6 kernel?
[21:14:17] <jdh> there is this section of 'Digital Machinist' magazine called 'Along the gcode way'. It has no gcode, just different ways of toy 3d printing.
[21:14:48] <jdh> I wouldn't care if they just called it "Along the 3d printer way"
[21:23:34] <failsafe247> can anyone explain to me why I would choose rtos-integration-preview3 or rtos-integration-preview3-merged-into-master?
[21:23:59] <failsafe247> I saw a recent commit and it looks like maybe the 2 have actually been merged
[21:24:10] <failsafe247> I am not really sure though
[21:24:19] <failsafe247> I am mostly concerned about picking the correct branch for easy future upgrades
[21:24:31] <failsafe247> Also, the reason I am using it is because I already built a full linuxcnc 3 axis cnc router based around a celeron 847 board
[21:24:45] <failsafe247> I am following the excellent writeup: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?NewRTInstall and have reached the part where I need to track a branch
[21:25:10] <failsafe247> thanks for any hel guys
[21:25:16] <failsafe247> ^help
[21:58:19] <pcw_home> How does the Celeron 847 card do latency wise? looks decent otherwise...
[22:04:56] <failsafe247> i dunno I havent fired it up yet
[22:05:04] <failsafe247> I was just about too though
[22:05:39] <failsafe247> I would avoid it though to due to not being able to use RTAI
[22:06:22] <failsafe247> It wont boot at all because the 2.6 kernel is not new enough
[22:06:26] <failsafe247> I tried it
[22:07:29] <failsafe247> Just fyi I am using: GA-C847N-D
[22:09:21] <failsafe247> It might work if you used an external video card (i.e. not intel hd graphics) but I dont plan on doing that
[22:09:57] <failsafe247> hence my question regarding Xenomai
[22:10:11] <failsafe247> but besides the kernel problem its a nice board
[22:10:44] <failsafe247> It has headers (not on the back connectors) on the pcb for 2 serial ports and a parallel port
[22:12:08] <pcw_home> Yes Gigabyte seems to make these for embedded applications
[22:21:25] <failsafe247> Here are some pics of my setup if you wanna see
[22:21:27] <failsafe247> http://www.flickr.com/photos/62760213@N03/sets/72157633279811058/
[22:22:24] <failsafe247> It's not 100% done but it's close
[22:33:44] <Connor> failsafe247: That case is HUGE.. Why so big ?
[22:34:44] <Connor> failsafe247: Or are you enclosing the whole machine ?
[22:34:47] <failsafe247> The entire router is going to have a 1/4" plexiglass case surrounding it. It has a hinge that attaches to the big red box part.
[22:34:50] <failsafe247> ^yup
[22:35:08] <Connor> http://www.ivdc.com/cnc/cnc13.JPG
[22:35:24] <failsafe247> Also, I am going to add a shelf inside the box and store endmills and not there
[22:36:08] <Connor> 36" Wide x 25" deep x 24" tall foot print.. with a 18" x 12" x 4.5" work envelope.
[22:36:22] <failsafe247> nice Connor. I used a Roland CNC router with an enclosure like that. I wanted to be able to get to all sides of my setup
[22:37:15] <failsafe247> ahh it wasnt a Roland, now I dont remember the name....
[22:37:58] <Connor> I want to get a aluminum exterusion like yours for my router top..
[22:38:21] <Connor> to be honest.. the router itself probably could be rebuilt with all alumn parts without much difficulty..
[22:40:12] <Connor> I would redo the main rails a bit..make them longer and bring the gantry straight down instead of that angle.. giving more distance on the gantry.
[22:42:21] <failsafe247> Well if I was to do it again, I wouldnt have gotten this Chinese 6040 Router either
[22:42:45] <Connor> What's the Z range ?
[22:42:55] <failsafe247> Also, now I remember about that other router. It was a Denford 6600 or 2600 with enclosure
[22:43:03] <failsafe247> The Z range is tiny
[22:43:27] <failsafe247> I'll measure actuals after I get it running though
[22:43:48] <failsafe247> Its probably 3"
[22:45:19] <Connor> 2.952"
[22:45:59] <Connor> mine has 4.5" with 6" clearance.
[22:47:50] <failsafe247> nice
[22:48:26] <Connor> Using 1610 Ball screws on the X and Y and 1605 on the Z
[22:50:56] <PetefromTn> Connor: Hey man whatryadoin?
[22:51:08] <Connor> Chiilin.
[22:51:40] <Connor> I saw your messages about the coolant trays.
[22:53:08] <PetefromTn> yeah bummer huh...
[22:53:19] <Connor> Yea.. just pop-marked with pin holes ?
[22:58:30] <PetefromTn> yup.... thinking Im gonna break out the ziss wheels and have at it....
[22:58:55] <Connor> Can you weld all of them up? or far too many ?
[23:02:02] <failsafe247> Well guys I am going to be afk till morning. I just wanted a short description of the pros and cons of picking the one Xenomia LinuxCNC branch over the other. Ill check in the AM to see if anyone commented. Thanks again.
[23:02:05] <PetefromTn> Honestly it is all over the place and while I probably could it would take as much time as replacing the bottom skins and I would still be left with a cheesy piece of metal. Been thinking about also going with some kinda fogbuster so I can make chips while I work on the trays...
[23:03:22] <Connor> Epoxy?
[23:07:46] <PetefromTn> Yeah I dunno.... I thought about it...I would have to sandblast them and tig weld the worst holes then spray it on THICK to keep it from rusting.....
[23:09:50] <PetefromTn> Just got pretty down when I looked at them this afternoon...
[23:10:11] <Connor> might be cheaper than welding a new bottom in place.. and probably would last longer
[23:11:17] <Connor> Can't believe the dumba$$ left it with coolant in it all that time for it to rust out.
[23:11:44] <PetefromTn> yeah pisses me off.... but whatryagonnado?
[23:12:10] <Connor> Yea. No sense in crying over spilled coolant.. I mean milk..
[23:12:48] <Connor> You can make your own fog buster pretty cheap.
[23:13:30] <PetefromTn> really? do you have one?
[23:13:42] <Connor> but, I have no doubt you'll get them fixed pretty quickly.
[23:14:16] <Connor> No. just my little pump from the Harbor freight Parts washer.. but, I've seen threads on making them.
