[03:50:00] <L84Supper> pcw_home: we are using a Asus F2A85-v Pro mainboard + A10 APU for RT-Preempt work, we have to finish the RTAI update to v3.8 to catch up with the drivers
[03:51:34] <L84Supper> https://www.asus.com/Motherboards/F2A85V_PRO/
[03:52:00] <L84Supper> http://www.newegg.com/Product/Product.aspx?Item=N82E16819113280&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-pla-_-Processors+-+Desktops-_-N82E16819113280&gclid=COX2jbzH07cCFdFDMgodKhQAIQ
[03:52:56] <pcw_home> How does it do latency wise with RT-Preempt?
[03:54:25] <L84Supper> we'll work on the E seies APU's next
[03:56:44] <L84Supper> we'll post some latency results in a couple of days
[03:57:00] <pcw_home> wow 3/4 of a teraflop
[03:58:41] <L84Supper> it's getting too hot while compiling with the stock cooler
[03:59:05] <L84Supper> using the other cores for image processing while running EMC
[03:59:36] <L84Supper> zedboards arrived to day
[03:59:46] <L84Supper> today even :)
[04:00:05] <L84Supper> http://www.zedboard.org/
[04:01:15] <L84Supper> wish they had 1GB vs only 512MB for DDR3
[04:02:04] <pcw_home> For linuxCNC if its not doing HMI 512 shoud be overkilll
[04:02:20] <pcw_home> should
[04:03:15] <L84Supper> Digilent shipped them overnight, Avnet said 3+ weeks
[04:05:17] <L84Supper> will try them with Linuxcnc on one ARM core and some simple image processing on the other
[04:06:35] <pcw_home> were looking an making an integrated FPGA/ARM system using a simple
[04:06:37] <pcw_home> backplane and cardcage. Do you know any good companies for doing card cages?
[04:07:57] <L84Supper> picked up a couple quad core A-7 1.2GHz A15 Mediatek smartphones, wish they had some IO
[04:08:35] <ssi> I've been working on some bitcoin mining fpga designs recently
[04:08:45] <ssi> working up to where we can build asic controlers for a friend of mine that's taping out a chip
[04:09:01] <L84Supper> pcw_home: something custom in sheet metal?
[04:11:11] <L84Supper> ssi:I was loking at that a few weeks ago, the ASIC route seemed to make the only sense
[04:11:25] <ssi> it is the only worthwhile endeavor nowadays
[04:11:40] <ssi> the first gen asics just started hitting the market and it's tearing the bottom out of the gpu market
[04:12:02] <ssi> even the fpga rig we're designing isnt' going to be anything like profitable
[04:12:19] <ssi> but it'll be a good dry run for figuring out things like inter-chip comms
[04:12:24] <L84Supper> 1K ASIC cluster and tune it just fast enough to mine the most without upsetting the difficulty settings
[04:14:10] <L84Supper> invest $5M to make a few thousand ASIC's, it looked profitable in a few weeks, not sure why somebody in China or Wall St hasn't done it yet
[04:15:22] <ssi> people are doing it
[04:15:28] <ssi> there's at least two vendors with fair scale
[04:15:29] <ssi> bfl and avalon
[04:15:36] <L84Supper> ssi: weren' these guys supposed to have ASIC's and then haven't released them do to unknown factors? http://www.butterflylabs.com/
[04:16:04] <ssi> yeah but they're starting to hit the market
[04:16:07] <ssi> supposedly
[04:16:12] <L84Supper> http://siliconangle.com/blog/2013/05/21/live-butterfly-labs-is-finally-shipping-asic-bitcoin-miners-start-digging/
[04:16:18] <ssi> the network difficulty certainly seems to reflect it
[04:17:25] <ssi> I've got 2.2MH of gpus running, but they're starting to not be so profitable :P
[04:19:44] <Connor> I bought one of this to use on de-burring alum etc.. http://www.harborfreight.com/1-in-x-30-in-belt-sander-60543.html Spent an hour or more trying to get the belt to line up with the back plate.
[04:20:03] <Connor> ended up having to shim the motor to get it to track correctly.
[04:20:13] <Connor> and shim the back plate on one side too.
[04:20:54] <L84Supper> Connor: heh, I had a similar experience
[04:21:03] <Connor> nice little unit.. other than that..
[04:21:06] <ssi> I have one of those
[04:21:14] <ssi> I use it in the hangar for shaping aluminum
[04:21:16] <L84Supper> ended up throwing it away after a project
[04:21:25] <Connor> Also got one of these.. http://www.harborfreight.com/4-inch-x-36-inch-belt-6-inch-disc-sander-97181.html
[04:21:26] <ssi> it's a bit faster than a scotchbrite wheel and much faster than a vixen file :)
[04:21:57] <pcw_home> L84Supper: yeah sheet metal
[04:22:02] <Connor> I had a 6 x 48 that my father-in-law loaned me.. it just too big for my shop.. so.. it's out in the car port right now..
[04:22:17] <L84Supper> believe it or else, they have even lower grade lines of power tools in China
[04:22:46] <L84Supper> pcw_home: we use a shop in Suzhou, they make 1sy 2sy and 1M+
[04:22:55] <Connor> or else? don't you mean believe it or not ?
[04:23:00] <L84Supper> been searching for more shops/factories
[04:23:15] <Tom_itx> is there an easy way to transfer ubuntu from one drive to another?
[04:23:35] <Tom_itx> something like ghost
[04:23:40] <Connor> dd
[04:23:48] <Tom_itx> i can't seem to get ghost to work
[04:24:10] <Connor> http://en.wikipedia.org/wiki/Dd_(Unix)
[04:25:02] <Tom_itx> will it format as well?
[04:25:11] -!- dhoovie [dhoovie!~kvirc@] has joined #linuxcnc
[04:25:17] <Connor> it's bit level.
[04:25:18] <L84Supper> Tom_itx: it does a bit for bit copy
[04:25:30] <Tom_itx> ok, similar to ghost then
[04:26:00] <Tom_itx> once it's done do or can i resize the drive to it's full capacity?
[04:26:20] <L84Supper> DD won't do that
[04:27:09] <Connor> You need to be using LVM for that..
[04:27:46] <Connor> lvm lets you resize a partition.. Not sure you can do that after the fact though.
[04:28:03] <L84Supper> http://en.kioskea.net/faq/2036-how-to-resize-a-partition-using-gparted-on-linux
[04:28:14] <L84Supper> be sure to backup first
[04:28:37] <Tom_itx> it is, i'm not worried about it
[04:28:52] <Tom_itx> i can start from the live cd if it doesn't work
[04:28:53] <Connor> well.. I would dd first.. the do the resize on the copy..
[04:29:08] <Connor> that way.. you still have the original.
[04:29:20] <L84Supper> DD always works unless you lose power during the copy
[04:29:20] <Tom_itx> and a spare on a SSD
[04:29:50] <Tom_itx> i got a cheap 500gb drive i was trying to use
[04:30:39] <Tom_itx> does the target drive need to be blank or does it matter?
[04:31:02] <Tom_itx> it's got ntfs on it atm
[04:31:05] <L84Supper> cordless drills in China are sold by the battery voltage
[04:31:34] <L84Supper> the better the battery the slightly higher the price
[04:32:33] <L84Supper> looks like the same actual drill, they just match them with the charger and battery voltage you want
[04:32:57] <Tom_itx> can you put gparted on a thumbdrive or does it need to be a bootable cd?
[04:33:49] <L84Supper> i thinks it's on the live cd
[04:34:02] <ssi> Connor: you guys figure out how to fixture those pulleys?
[04:34:09] <Tom_itx> ok
[04:34:29] <Connor> I'm going to buy a 4" chuck to mount on my 4" rotary.. and we'll make a adapter plate.
[04:34:59] <ssi> yow
[04:35:41] <Connor> I have a make shift adapter plate and took my 3" chuck off of my mini lathe.. but.. the holes for the grub screws didn't turn out very well.. had too much run out..
[04:35:57] -!- LeelooMinai [LeelooMinai!~leeloo@] has joined #linuxcnc
[04:37:25] <Connor> ssi: Yea.. not sure what else to do.. about the only way to do it ..
[04:40:37] <Connor> now, my question is.. how the heck do you get a 4th axis trammed up with your spindle..
[04:41:06] <L84Supper> pcw_home: what's your PCIe FPGA baord with the most amount of gates? and is there any DDR on board?
[04:42:33] <L84Supper> or PCI
[04:43:36] <ssi> Connor: depends how hard you need to try
[04:43:58] <Connor> You kinda want these to be as dead on as you can get..
[04:44:40] -!- dgarr [dgarr!~dgarrett@71-223-69-74.phnx.qwest.net] has parted #linuxcnc
[04:44:43] <ssi> well you can chuck a testbar in the chuck, and spin the 4th with two indicators on the bar, and dial it in til it's perfectly parallel to the 4th
[04:44:52] <ssi> ie concentric and parallel, so both indicators run true
[04:45:03] <ssi> if you only use one indicator it can run concentric but conically (not parallel)
[04:45:31] <ssi> then once it's true, you can tram the whole axis to the spindle by running an indicator the length of the bar, like you were tramming in a vise
[04:45:52] <ssi> would need to run it along the front edge and the top edge and tram it in both axes
[04:46:36] <Connor> yea. I'll leave that up to Pete.. and watch how he does it..
[04:46:52] <Connor> But first, we have to make that adapter plate..
[04:47:07] <Connor> I hope the 3/4" thick alum plate I have will work for it.

[14:51:14] <jdh> any machinist types around? I want to cut a rectangular 1" x 0.5" profile in a 0.5" 6061 sheet with a 0.25" endmill.
[14:52:31] <archivist> whats the real question
[14:52:32] <jdh> and be able to put a 1" x 0.5" tab into the resulting hole. Can I just drill the corners of the profile with a .25" and have the tab fit into the hole?

[14:54:10] <jdh> does this exist?
[14:54:20] <skunkworks> I just run the mill out at each corner at a 45deg path
[14:54:24] <archivist> internal square corners is probably the real question
[14:54:35] <skunkworks> if you don't care how the hole looks
[14:54:47] <jdh> that is the real question,now that you put it that way
[14:54:48] <jdh> kind of
[14:55:18] <jdh> how do I fit a rectangular tab into a hole cut with an endmill
[14:55:46] <archivist> round the corners of the tab is one way
[14:56:00] <skunkworks> http://www.electronicsam.com/images/boring.jpg
[14:56:14] <skunkworks> I thought I had a picture of a fixture milled that way...
[14:56:18] <skunkworks> but I don't
[14:56:36] <skunkworks> but - the rounded tab as archivist mentioned is sort of what you see...

[14:57:25] -!- mhaberler [mhaberler!~mhaberler@macbook.stiwoll.mah.priv.at] has joined #linuxcnc
[14:58:50] <jdh> rounding the corners of the tabs sounds more difficult than drilling out the corners or doing the 45 thing
[14:59:21] <jdh> The plan is to chamfer the backsides of the tab and the plate and have them welded.
[14:59:30] <skunkworks> we made some 'square' pockets with a larger mill - then finished it off with a 1/16 mill. (then I think dad chislled them square..)
[15:00:21] <archivist> for clock keys we drilled round and then broached to square
[15:01:29] <jdh> http://www.artichoke.org/ladder-mount.pdf
[15:01:55] <jdh> that is the initial idea
[15:02:11] <skunkworks> I would do what archivist says - make them round.
[15:02:20] <skunkworks> *round corners
[15:02:36] <jdh> is that better/worse/indifferent for welding?
[15:03:25] <archivist> may be better as less need to stop while welding
[15:04:08] <archivist> depends on skill of welder and quality required

[15:33:19] <ssi> jdh: predrill the corners with a 1/8" drill and finish your internal pocket with 1/8" endmill
[15:33:40] <ssi> you'll end up witha 1/16" radius "mousehole" at the corners, but if it's being welded that's easy to fill and won't show up
[15:33:48] <ssi> aluminum fillet is going to be considerably wider than that
[15:34:10] <ssi> welding half inch aluminum to half inch aluminum in a corner weld is gonna be at least a 3/8" wide bead
[15:35:46] <jdh> cool
[15:36:05] <jdh> 45 chamfer on both parts sound reasonable?
[15:36:12] <ssi> yep
[15:36:34] <jdh> finding a welder is the hard part.
[15:36:35] <ssi> now you just gotta consider your fit tolerance
[15:36:59] <ssi> what part of the world are you in
[15:37:15] <jdh> wilmington, NC, South East Coast.
[15:37:21] <jdh> lots of marine Al welders around
[15:37:30] <ssi> well if you get stuck and want to come to atlanta
[15:37:37] <ssi> I've got a pet certified aerospace welder
[15:37:38] <PetefromTn> I can tig weld aluminum..
[15:37:46] <ssi> depending on how critical it is ;)
[15:38:01] <ssi> I can tig aluminum too, but for critical stuff I always let dan do it
[15:38:02] <jdh> heh. The ladder part is going to be 2" square aluminum with 1.25" OD tubing through it for rungs.
[15:38:52] <jdh> I was planning on cutting everything nominal and adding 'tolerance' with a file

[16:11:36] <pfred1> oh I've used it does it support imperial measurements yet?
[16:11:52] <pfred1> or is the lead nazi running that project still dead set against it?

[16:12:34] <PetefromTn> There are simple workarounds tho.
[16:12:49] <PetefromTn> I drew that part in what I consider imperial measurements

[16:43:35] <pfred1> I don't think you can get much of a BOB for $30
[16:43:43] <IchGuckLive> lots of fun and milling the own way is more fun

[17:21:24] <pfred1> rodger is getting up there in the years now
[17:21:29] <PetefromTn> Huge Freakin' bronze churchbell balls..
[17:21:37] <pfred1> if i walked up to Rodger he'd have a heart attack
[17:21:50] <pfred1> because i look just like my old man
[17:22:01] <pfred1> it'd be like seeing a ghost or something

[17:22:31] <PetefromTn> If he drove Formula1 cars I find that very hard to believe
[17:22:42] <pfred1> well he was mark's second back in the 60s
[17:22:52] <pfred1> then when mark died that was that
[17:23:07] <PetefromTn> IMHO ANyone who is given the opportunity to pilot one of those monsters is a giant among men.
[17:23:41] <PetefromTn> Especially back then when the cars were overpowered monsters with little in the way of brakes and suspension technology.
[17:23:42] <pfred1> I think i even knew mark when I was a little kid
[17:23:55] <pfred1> I think he came over the house
[17:24:07] <PetefromTn> Are you in UK?
[17:24:17] <pfred1> no I grew up where Mark did
[17:24:30] <pfred1> http://en.wikipedia.org/wiki/Mark_Donohue
[17:24:31] <PetefromTn> Where was that?
[17:24:37] <pfred1> it says in the article
[17:24:49] <pfred1> Donohue grew up in Summit, New Jersey.
[17:24:56] <pfred1> I did too
[17:25:01] <PetefromTn> Oh a joysey boy..
[17:25:08] <pfred1> yuppers
[17:25:13] <pfred1> a yankee
[17:25:16] <PetefromTn> I've been to Cherry Hill..
[17:25:21] <PetefromTn> and Wildwood.
[17:25:26] <pfred1> I've been through cherry hill
[17:25:32] <PetefromTn> Almost married a beautiful Girl from there...
[17:25:35] <pfred1> only because it is on the TPK
[17:25:53] <pfred1> you can see the water tower from the highway
[17:26:00] <PetefromTn> LOL..
[17:26:05] <pfred1> well you can
[17:26:13] <PetefromTn> She worked at Cherry Hill Pizza next to the food lion.
[17:26:14] <pfred1> it says Cherry Hill on it
[17:26:29] <pfred1> I think it has a cluster of cherries painted on it now too
[17:26:37] <PetefromTn> We met in Disney World...
[17:26:46] <pfred1> I've been to Disney World
[17:26:54] <PetefromTn> Love Disney World..
[17:26:57] <pfred1> I was there the year after it opened
[17:27:07] <pfred1> it was very clean then
[17:27:14] <PetefromTn> Did ya get to meet Walt?
[17:27:20] <pfred1> the last time I was there it was like a slum
[17:27:37] <pfred1> the sidewalks were all dirty stained and cracked
[17:27:37] <PetefromTn> Really, I was there a year or two ago and it was quite nice.
[17:27:58] <pfred1> trust me it was really nice when it first opened
[17:28:07] <pfred1> when it was all new
[17:28:19] <PetefromTn> Isn't everything?
[17:28:34] <pfred1> I bet if walt was still alive it'd still be that nice today if not nicer
[17:28:44] <pfred1> walt didn't play games
[17:28:47] <PetefromTn> MOst likely...
[17:29:12] <pfred1> disney world isn't what it was supposed to be
[17:29:27] <pfred1> it was supposed to be a perfect community not so much a theme park
[17:29:44] <PetefromTn> The only thing I don't like about it now is the prices..
[17:29:55] <pfred1> nothing is cheap
[17:30:06] <PetefromTn> You can say that again.
[17:30:30] <pfred1> I was just reading an article about people hiring handicapped people for their passes so the ycan cut lines in the park
[17:30:43] <pfred1> doing that costs $500 a day
[17:31:00] <PetefromTn> what a joke.
[17:31:13] <pfred1> yeah Disney didn't think it was too funny when it got exposed
[17:31:45] <pfred1> you thought how you went to the park was expensive
[17:32:07] <PetefromTn> They just raised the prices again.
[17:32:20] <pfred1> but when you hire a handicapped guide you can do in one day what would take 5 to do
[17:32:43] <pfred1> so I guess it is worth it

[17:34:42] <pfred1> I'm out of argon
[17:34:54] <PetefromTn> Sucks... I hate it when that happens..
[17:34:54] <pfred1> now all I'm doing is stick welding
[17:35:06] <pfred1> my bottle has a leak
[17:35:07] <PetefromTn> Got DC?
[17:35:19] <pfred1> oh yes my welder does DC
[17:35:28] <PetefromTn> DC stick is great...
[17:35:32] <pfred1> it's OK
[17:35:38] <pfred1> DCEN
[17:35:55] <PetefromTn> I use it for REAL thick stuff all the time.
[17:36:01] <pfred1> I can do a better job with a TIG torch though
[17:36:14] <PetefromTn> Of course but not on thick stuff...
[17:37:00] <pfred1> I stick welded this last week http://i.imgur.com/VA6JRLD.jpg
[17:37:15] <pfred1> if I ground it out and passed it again maybe I could have cleaned it up some more
[17:37:28] <PetefromTn> Cast?....
[17:37:33] <pfred1> you bet
[17:37:41] <pfred1> worse than that very old casting
[17:37:50] <pfred1> like over 100 years old
[17:38:33] <pfred1> in mint condition that plane would be worth north of $400
[17:39:22] <pfred1> it is a Stanley No.2
[17:39:27] <PetefromTn> Not to me... I used to do high end custom woodworking, now I do metal..
[17:39:30] <archivist> just looks like a standard broken plane
[17:39:48] <pfred1> archivist it is half the size of a common No.4
[17:40:00] <pfred1> I should take a picture of it next to a regular plane
[17:40:44] <archivist> you can get as new welding done on cast iron
[17:40:50] <pfred1> like the piece of wood behind it in this picture is about a half of an inch wide http://i.imgur.com/kNTYdYY.jpg
[17:41:40] <archivist> get this company to weld it for you http://www.castironwelding.co.uk/
[17:41:57] <pfred1> archivist I could just grind it out and TIG it if I cared
[17:42:14] <pfred1> I even have the cast iron nickle rod
[17:42:21] <pfred1> nickel even
[17:42:29] <archivist> wrong way to fix
[17:42:42] <pfred1> how so?
[17:42:58] <archivist> that company uses cast sticks and gas welds
[17:43:09] <archivist> seriously better
[17:43:17] <pfred1> I have TIG rod made to weld cast iron with
[17:43:40] <pfred1> guy at a supply house gave me a few because htey are insanely expensive to buy
[17:43:43] <archivist> are you heating the whole thing first
[17:43:51] <pfred1> no preheat
[17:43:58] <archivist> wrong
[17:44:03] <pfred1> it didn't crack
[17:44:08] <archivist> you will get cracking
[17:44:14] <pfred1> well it didn't
[17:44:21] <PetefromTn> you got lucky...
[17:44:23] <pfred1> this isn't the first peice of cast iron I've ever welded
[17:44:40] <pfred1> oldest piece
[17:44:54] <PetefromTn> I often have to Tig weld cast pieces for customers and a good preheat and a slow cooling down is real important to avoid cracking.
[17:44:54] <pfred1> thng is from before 1895
[17:45:08] <PetefromTn> Sometimes it STILL cracks anyways.

[17:45:49] <pfred1> you have a water cooled torch?
[17:45:53] <PetefromTn> I have to spend an hour or more just heating the area before I tig weld it
[17:46:05] <PetefromTn> then it still sometimes cracks.
[17:46:13] <PetefromTn> Yeah but I seldom use it.
[17:46:19] <pfred1> maybe you should just braze it?
[17:46:42] <archivist> PetefromTn for smaller bells, we silver soldered some
[17:46:51] <pfred1> yeah i have silver solder
[17:47:15] <pfred1> next you'll be repairing the Liberty Bell
[17:47:27] <archivist> getting a broken clock bell to ring again :)
[17:47:53] <pfred1> kinda dumb one of our nation's symbols is a freaking cracked bell
[17:47:59] <PetefromTn> Actually this is what the customer wants. He actually restores these huge bells
[17:48:14] <PetefromTn> He has a special van equipped to move them
[17:48:24] <pfred1> hard to find old bells in europe
[17:48:32] <PetefromTn> It has a huge sliding gantry in it.
[17:48:38] <Jymmm> pfred1: Nah, give it character.... Broken but still goin
[17:48:43] <pfred1> they always get melted down to make bullets out of
[17:49:06] <pfred1> do they ever ring the Liberty Bell?
[17:49:17] <pfred1> or are they worried it will crack more?
[17:49:44] <PetefromTn> Some of these bells are really THICK.
[17:49:57] <pfred1> get good scrap money for them
[17:49:58] <PetefromTn> I often have to grind out the crack almost to breakthru

[17:56:42] <Crashdemon> my z-axis loosing steps between up and down. any suggestions?
[17:56:54] <Crashdemon> current lowering is disabled
[17:57:34] <pfred1> stepper?
[17:57:48] <archivist> add some counter balance, get better steppers, reduce your speeds and acceleration values
[17:58:08] <pfred1> yeah if stepper I was going to suggese slower acceleration or slower top speed
[17:58:10] <FinboySlick> Reduce microstepping.
[17:58:17] <pfred1> reduce?
[17:58:35] <FinboySlick> Well, less microstepping is usually more hold torque, no?
[17:58:42] <archivist> move to half step
[17:58:51] <pfred1> they say missing steps not slipping
[17:59:23] <pfred1> as far as holding torque goes what step mode shouldn't matter
[17:59:37] <pfred1> steppers aren't moving when they are holding
[18:00:03] <Crashdemon> tried slower accel. + speed, no improvement
[18:00:13] <archivist> Crashdemon, http://www.micromo.com/microstepping-myths-and-realities.aspx
[18:00:34] <Crashdemon> i'm using microstepping by default
[18:00:45] <pfred1> well there are different microstepping modes
[18:01:00] <pfred1> half, quarter, eigth etc.
[18:01:20] <pfred1> I've seen up to 256
[18:01:54] <Crashdemon> half stepping
[18:02:16] <Crashdemon> isel isert stepper 3455
[18:02:47] <Crashdemon> in combination with isel driver / ctrl.
[18:03:05] <pfred1> Crashdemon what kind of motor drivers do you have?
[18:04:02] <Crashdemon> l298
[18:04:10] <pfred1> hmmm
[18:04:41] <pfred1> they only have full or half step mode don't they?
[18:05:05] <Crashdemon> jap, thats right
[18:05:44] <Crashdemon> phase current to low?
[18:05:49] <pfred1> they are kind of old today
[18:05:58] <archivist> use as much current as you can
[18:06:05] <pfred1> are you running the highest voltage you can?
[18:06:21] <pfred1> they're good to what like 34V?
[18:06:45] <archivist> a 2A motor needs 2A, and for speed use the max voltage you can
[18:06:55] <Crashdemon> im using the isel controller out of the box, i'm not sure wich voltage they run at
[18:06:58] <pfred1> well they are choppers
[18:07:16] <pfred1> bipolar choppers
[18:08:15] <pfred1> Crashdemon to get the best performance you can out of stepper motors and drivers you need to run them at the highest voltage the drivers can handle
[18:08:19] <pfred1> that is a universal given with the things
[18:09:07] <pfred1> with a PWM chopper driver the voltage doesn't really matter as far as what the motors can handle it is all current
[18:09:14] <Crashdemon> yes i know, the l297 controlles / limits the current through each phase
[18:09:19] <pfred1> right
[18:09:43] <pfred1> as long as you don't exceed the insulation breakdown voltage of the coil or the current rating you are OK
[18:09:45] <archivist> do not worry about warm/reasonably warm motors
[18:09:56] <pfred1> yeah stepper motors get cooking hot
[18:10:40] <pfred1> unless you have hild current reduction
[18:10:43] <Crashdemon> ok, i will try to increase the phase current
[18:10:45] <pfred1> hold even
[18:10:51] <archivist> my 5 axis has one motor without enough heatsink, it makes people jump when they lean on it
[18:10:56] <pfred1> well not the current
[18:11:04] <pfred1> you need to increase the voltage to the drive
[18:11:22] <pfred1> you see as a stepper motor runs the faster it goes the less current it can draw
[18:11:36] <pfred1> it has to do with the inductive reeactance of the motor coils
[18:11:55] <pfred1> as you run faster yoru dwell time on the coils goes down
[18:12:09] <pfred1> that is why you have to pump more voltage through them
[18:12:10] Cylly is now known as Loetmichel
[18:12:30] <pfred1> just to try to increase the current
[18:12:50] <Crashdemon> the voltage is fixed!
[18:12:54] <pfred1> but yo ucan't increase the driver current because at slower speeds you will over current
[18:13:18] <pfred1> what do you mean the voltage is fixed?
[18:13:24] <Crashdemon> as i said i'm using stepper + manufacture controller
[18:13:34] <pfred1> the voltage is whatever your power supply outputs
[18:14:18] <archivist> the current is whatever he sets the load R at
[18:14:21] <pfred1> well there are motors drivers and supplies
[18:14:38] <pfred1> archivist yeah but yo ucan't exceed the motor's current rating
[18:14:45] <archivist> I know
[18:14:57] <pfred1> well the only place yo ucan fool around is your input voltage
[18:14:59] <Crashdemon> this means i've a rack slide +230V AC comes in and the voltage will be down transformed to, i think +30v dc
[18:15:32] <archivist> 30 is reasonable for L298 iirc
[18:15:41] <pfred1> yeah if you're already running at 30V 34V isn't going to set the world on fire for you
[18:16:28] <pfred1> I mean it'd help a little on the top end but I'm not even sure if it would be noticable
[18:17:28] <pfred1> OK how many wires are the motors?
[18:17:33] <pfred1> 4 or 8?
[18:17:47] <archivist> or 6
[18:17:53] <pfred1> nah that is unipolar
[18:18:04] <Crashdemon> 2-phase motor
[18:18:10] <archivist> 5 is only unipolar
[18:18:12] <pfred1> it can still be 4 or 8
[18:18:18] <archivist> or 6
[18:18:18] <pfred1> unipolar is 6
[18:18:34] <pfred1> well maybe you can combine the commons
[18:18:35] <archivist> you can run a 6 wire as bipolar
[18:18:42] <pfred1> yeah half coil
[18:19:02] <archivist> no two in series
[18:19:10] <Crashdemon> one moment
[18:20:27] <pfred1> my machine has bipolar and unipolar but I drive each with the correct type of drive
[18:20:39] <pfred1> I've only read about unipolars ad bipolars I never tried it
[18:20:44] <Crashdemon> 1,8 deg, 2 coils
[18:20:58] <pfred1> they still have wires coming out of them
[18:21:08] <pfred1> they either have 4 or 8
[18:21:23] <pfred1> if they have 4 there is nothing you can do
[18:21:31] <pfred1> if they have 8 there is something you might be able to do
[18:22:09] <pfred1> an 8 wire motor is a so called universal stepper motor
[18:22:36] <pfred1> which can be wired up as unipolar or bipolar series or bipolar parallel
[18:22:59] -!- adb [adb!~IonMoldom@] has joined #linuxcnc
[18:23:00] <pfred1> bipolar parallel is the highest performing configuration of the 3
[18:23:51] <pfred1> most folks do want the highest performance they can get too
[18:24:23] <Loetmichel> .... if the driver can cope with the current and resistance of two parallel windings ;-)
[18:24:31] <pfred1> although a series wired motor will run faster
[18:24:36] <pfred1> well there is that too
[18:24:46] <pfred1> if your driver can't drive it in parallel you have to run series
[18:25:01] <pfred1> it still might perform better under driven in parallel though
[18:26:00] <pfred1> series really has no torque at any higher speeds

[22:00:06] <jdh> that's quite a trip from your area
[22:00:31] <andypugh> Yes, it is a lot of tedious flying.
[22:00:41] <andypugh> But it beats walking.
[22:01:56] <Tom_itx> andypugh, where did you decide to stay?
[22:02:03] <andypugh> Hampton
[22:02:20] <Tom_itx> that's right on the corner of the highway and west
[22:02:33] <Tom_itx> so you won't have far to go to either place
[22:02:46] <andypugh> Yes, seemed sensible to be within walking distance (even if walking is a felony in the US)
[22:03:03] <Tom_itx> lots of eatery nearby as well
[22:03:15] <Tom_itx> all along west st to the North
[22:03:33] <Tom_itx> his shop is to the south
[22:04:42] <Tom_itx> starbucks right across west st if you're into coffee

[22:17:03] <jdh> ballscrew on a bike?
[22:17:26] <andypugh> :-)
[22:18:06] <andypugh> I needed to get it to a lathe with sufficient spindle bore to machine the ends.
[22:18:31] <andypugh> An old Colcheser Student and a CBN onsert worked _beautifully_.
[22:19:53] <andypugh> One of my friends was in the workshop at the same time and videoed it, a yellow-hot stream of swarf coming off (1600rpm).
[22:20:47] <Tom_itx> reminds me of watching that Mori Seki with the shell mill cleaning off some steel plate
[22:20:48] <andypugh> You don't need a super high-tech lathe to do hard-turning, anything made properly and solid enough is fine.
[22:22:11] <andypugh> (But it was very nice of Yamaha to make a suitable space on the R1 for carrying ballscrews)
[22:29:53] <andypugh> This is odd. If you search ebay (US) select worldwide and look for a Rivett 608 you do _not_ find the one that I am trying to resist buying. http://www.ebay.com/itm/Rivett-608-for-parts-or-restoration/321137853023
[22:30:57] <Tom_itx> resistance is futile
[22:33:40] <andypugh> I had decided that it was a bad CNC conversion candidate, but there is no gearbox to waste. Flat-belt and VFD is actually probably quite a reasonable system. The entire cross-slide _and_ top-slide pop off with a single lever, to I could swap between CNC and manual slides instantly. The only real problem is that I think that there is almost no room around the leadscrew (it actually uses a single-half nut in original spec

[22:35:39] <Tom_itx> i took one of my old pc's out to the shop for the sherline but it's taking up too much space
[22:36:11] <jdh> A BBB would be perfect for that
[22:36:21] <Tom_itx> probably so
[22:36:26] <andypugh> For the current price I am tempted to buy it _then_ decide if I want it.
[22:36:33] <jdh> need a mesa interface for BBB

[23:11:53] <andypugh> It's not anything I recognise as cartography, basically.
[23:12:26] <Tom_itx> oh those are counties
[23:12:33] <ssi> headed right for midcontinent :P
[23:12:33] <andypugh> Maps are made of wiggly lines, largely defined by cows, in my experience.
[23:12:34] <Tom_itx> states are darker outlines
[23:12:38] <Tom_itx> yeah
[23:13:09] <Tom_itx> but we're flat like a checker board here :)
[23:13:19] <ssi> andypugh: our flatlands have few landmarks to use as natural borders
[23:13:22] <ssi> so there's lots of square ones
[23:13:35] <andypugh> Yes. I think that is going to feel very strange.
[23:13:40] <Tom_itx> heh i bet
[23:13:56] <Tom_itx> lots of wheat
[23:14:05] <ssi> still plenty of cows
[23:14:10] <Tom_itx> when you fly in you will see alot of circles from the air
[23:14:14] <ssi> but our cows don't stand on the sides of hills like yours do
[23:14:16] <ssi> cause there's no hills
[23:14:17] <ssi> hahaha
[23:14:20] <Tom_itx> those are irrigation sprinklers

[23:16:13] <andypugh> Industrial West Yorkshire (that's a wool mill at the bottom of the valley)
[23:16:33] <ssi> andypugh: the area where I live isn't too far off from that
[23:16:37] <ssi> but it's a bit less... pastoral
[23:16:39] <ssi> and more hillbilly
[23:16:40] <ssi> :D
[23:17:00] <Tom_itx> we have the flint hills but not quite like that
[23:18:27] <ssi> I can't figure out how to get into that street view mode
[23:18:41] <andypugh> If you follw that road down to the sharp left-hand bend where the tree is you can see where the wall got demolished by a lost trucker. They had a low-loader (to transport a crane). They had no way to turn round, and dragged the whole thing through the wall/bend/tree.
[23:19:24] <andypugh> ssi: You see the little orange mannikin on the zoom bar in map mode? Drag him to the stret where you want to stand.
[23:19:31] <ssi> ahh

[23:22:54] <andypugh> Ah, ok.
[23:23:25] <andypugh> A "Civil war" what on odd idea. "No, I insist, you shoot first, it's only fair"

[23:23:57] <ssi> A war between citizens of the same country.
[23:23:58] <ssi> :D
[23:24:32] <ssi> The term is a calque of the Latin bellum civile which was used to refer to the various civil wars of the Roman Republic in the 1st century BC.
[23:24:36] <andypugh> Oh, just one more pic from that road you might have missed: The trucker ignored this: https://maps.google.co.uk/?ll=53.613717,-1.916556&spn=0.028463,0.055919&t=h&layer=c&cbll=53.61363,-1.916595&panoid=B728Dj0aFJgEabZJ90lftg&cbp=12,199.59,,1,9.04&z=15
