[07:38:23] <jthornton> holy crap batman pyngcgui in my custom GUI!
http://imagebin.org/245323
[07:39:16] <cncbasher> great jt :
[07:39:38] <jthornton> it's all Deweys doing
[07:39:53] <jthornton> the file gtsy.py shows how to do it
[07:40:07] <jthornton> did you try touchy with ngcgui?
[07:40:41] <cncbasher> not as yet
[07:40:58] <cncbasher> gscreen next !
[07:41:38] <cncbasher> is that with 2.5 or dev master ?
[07:41:49] <jthornton> 2.5
[07:42:07] <cncbasher> ok thanks
[07:42:20] <jthornton> I copy the files to the installed directories and just run linuxcnc config.ini
[07:42:25] <cncbasher> iv'e just downloaded deweys patch
[07:44:55] <cncbasher> can you mail the files over
[07:45:25] <jthornton> yea, but I forget your email
[07:50:13] <jthornton> woot! I got it to work with the ini configured to load my subs
[07:50:32] <jthornton> I wish we could upload to the forum so I could show it
[07:51:21] <jthornton> now I just have to figure out how to send the file to my gui
[07:51:43] <cncbasher> yea uploading to the forum is a pain at the moment
[07:52:44] <jthornton> the response I got from the Kunena forum is "we don't support out of date, upgrade Joomula and Kunena"
[08:07:25] <ReadError> https://www.youtube.com/watch?v=u2H0MrhXmo4
[08:07:30] <ReadError> im pretty impressed by this
[08:15:02] <Icekiller> hmm looking for some cheap bf12's / bk12's.. anyone have any recommendations?
[08:28:10] <Loetmichel> ReadError: looks familliar
[08:28:38] <Loetmichel> thats about the cutting deptz MY mill can cope with
[08:28:51] <Loetmichel> in aluminium
[08:29:06] <ReadError> Loetmichel: thats a big router
[08:29:26] <ReadError> suprised to see it cutting like that
[08:29:33] <Loetmichel> bigger than this:
http://www.cyrom.org/palbum/main.php?g2_itemId=4935 ?
[08:29:34] <Loetmichel> ;-)
[08:29:39] <ReadError> just tearing through aluminum
[08:29:51] <ReadError> yea i think
[08:29:54] <ReadError> 48x48"
[08:30:10] <ReadError> 1.2192m ?
[08:30:42] <Loetmichel> hrhr, hte router on the pic can move 1500*1020mm
[08:32:31] <Loetmichel> and this one is even bigger:
http://www.cyrom.org/palbum/main.php?g2_itemId=11205 (1700*1200 IIRC)
[08:32:45] <Loetmichel> and yes, they can do the same in Al
[08:40:59] <ReadError> is that a chinese VFD?
[08:41:05] <ReadError> I was thinking about going that route..
[08:41:10] <Loetmichel> yes
[08:41:12] <ReadError> spindle+VFD
[08:41:29] <Loetmichel> yes
[08:41:39] <Loetmichel> 2200W iirc
[08:42:13] <Loetmichel> on the photo is a kress mointed, but shince upgraded
[08:42:17] <Loetmichel> -h
[08:42:38] <Loetmichel> let me see if i find some photos with spindle + VFD
[08:42:54] <Loetmichel> the big router isnt mine, i had just helped to build it
[08:45:30] <Loetmichel> MarkusBec: are you there?
[08:45:59] <Loetmichel> do you have some photos of lilalinx' machine with the CHinese Spindle?
[08:46:09] <Loetmichel> (he is the one on the last photo)
[08:48:26] <Loetmichel> hmm, sorry, he seems to be offline
[08:49:56] <Loetmichel> ReadError: found one on his site:
http://markusbec.deswahnsinns.de/main.php/v/fraese/fraese_mbechtold.jpg.html?g2_imageViewsIndex=1
[08:51:12] <ReadError> oo
[08:51:14] <ReadError> looks tiny
[08:51:28] <Loetmichel> on a big machine: yes
[08:52:14] <ReadError> what size motors?
[08:52:24] <ReadError> im pretty sure im going with 23s
[08:52:26] <Loetmichel> E240 servos
[08:52:30] <ReadError> ahh fancy
[08:53:23] <Loetmichel> remember: the machine has ~1700*1200 movement
[08:53:29] <Loetmichel> mm
[08:54:12] <Loetmichel> the "wood" is nearly 1" thick
[09:02:04] <Loetmichel> ReadError: thats my little machine "drilling" a 20mm hole in aluminium tube with a 2mm mill bit. 800W chinese Spindle ->
http://www.youtube.com/watch?v=UEd4LCJ3uWk (caution, LOUD)
[09:03:00] <Loetmichel> correction: 15mm hole ;-)
[09:03:57] <Loetmichel> and if i hadn bought this "chewing gum" extruded aluminium i could have gone triple speed
[09:04:24] <Loetmichel> so i had to see that the mill bit doesent get cloggged with molten/smeared alu
[09:06:21] <Loetmichel> http://www.youtube.com/watch?v=BXNhsid6PD0 <- here i make "some" 2.5mm holes in a 1.5mm thick aluminium with a 2mm mill bit :-)
[09:13:40] <ReadError> wish i had a cheap CF source :(
[09:14:28] <ReadError> https://dl.dropbox.com/u/25091878/Photo%20Feb%2001%2C%2012%2004%2053%20PM.jpg
[09:14:35] <ReadError> thats my latest work
[09:14:51] <ReadError> i forgot to g28.1 so it cut a gash
[09:14:55] <ReadError> on the top piece
[09:20:41] <Loetmichel> nice
[09:21:28] * Loetmichel is still not further with is hexa... -> http://www.cyrom.org/palbum/main.php?g2_itemId=12997
[10:01:56] <anonimasu> Loetmichel: I had a shitty job like that once.. 280 holes in a 70mm copper disc, 1cm thick
[10:08:25] <Icekiller> question guys the.. BK/BF 12 .. is tere a cheaper solution for those or?
[10:17:09] <archivist> someone already told you :) make your own
[10:17:48] <Icekiller> wow :P
[10:17:56] <Icekiller> must be really tired than xD
[10:18:19] <Icekiller> didn't see any responds to be as far as i can tell :P
[10:18:35] <Icekiller> what makes BK BF expesnive..? the internal bearing? or the surround part?
[10:19:59] <archivist> or the joining of the two
[10:36:37] <r00t4rd3d> ReadError, what is that blue material?
[10:37:36] <ReadError> g10
[10:37:42] <ReadError> i didnt want to use up all my black
[10:37:50] <jdh> what's it weigh?
[10:37:55] <ReadError> 430g
[10:38:04] <ReadError> but over 4kg of thrust
[10:38:15] <ReadError> 4.4-4.5kg
[10:38:44] <jdh> you should slot the motor mounts in the other plane
[10:39:01] <ReadError> why?
[10:40:59] <jdh> because it would look cool
[10:41:16] <jdh> how thick are they?
[10:46:38] <ReadError> aluminum?
[10:46:39] <ReadError> 1/4
[10:46:49] <ReadError> but ive hollowed out the underside a bit

[10:47:42] <jdh> they look nice. Did you have to clean up any edges or anythying?
[10:48:52] <IchGuckLive> hi all
[10:49:33] <IchGuckLive> Superbowl sunday
[10:50:03] <jdh> hockey?
[10:50:37] <IchGuckLive> live in Europ at 0.10 SAT1
[10:50:38] <ReadError> jdh: I took a file to the corners edges
[10:50:42] <ReadError> they are super sharp otherwise
[10:51:43] <jdh> I'd like to try going over some edges with a roundover bit

[11:00:31] <r00t4rd3d> you have to do that for fanboy channels
[11:00:35] <IchGuckLive> they dont like us
[11:00:49] <Tecan> fanboy channels ?
[11:00:51] <ReadError> lol
[11:00:53] <ReadError> its just Tecan
[11:00:53] <archivist> ## is for general non project specific

[11:04:04] <r00t4rd3d> well their tracking site does sometimes
[11:23:08] <anonimasu> Icekiller: probably the ground spacer ring or modified face's of the bearings to apply preload

[11:37:16] <Icekiller> IchGuckLive ?
[11:38:46] <Loetmichel> anonimasu: i've made about 30 of these units 'til now...
[11:38:57] <Loetmichel> in 3 to 6 doublepacks
[11:39:29] <Loetmichel> they are the Top/bottom plates for a "5,25" usb Drive"

[11:40:30] <Loetmichel> because the computers my company makes are shielded against eavesdropping and have a front lid
[11:47:10] <anonimasu> I see
[11:50:13] <anonimasu> tomorrow will be the day of hell, aligning tailstock and cutting shafts out of ss2225
[11:50:55] <anonimasu> 130mm dia and they go down to 100mm and 80 when dne
[11:50:55] <anonimasu> done
[11:51:20] <anonimasu> then off to harden and finish machine with a pcbn insert..
[11:51:47] <Icekiller> IchGuckLive :P wth man
[11:51:55] <anonimasu> 60hrc.. -_-
[11:55:03] <anonimasu> it'll be interesting to say at least.
[11:56:58] <archivist> finish after harden can mean it starts bending as you release strain :)
[11:58:24] <anonimasu> 1mm left to finish after hardening probably will not deform my part very much
[11:59:15] <anonimasu> im more worried how the threads on it will go after hardening
[12:00:46] <archivist> through or case hardening ?
[12:01:04] <anonimasu> through
[12:01:26] <anonimasu> the hardener I have locally said that the dimensional change is usually around 0.2%
[12:01:28] <Loetmichel> case hardening with 1mm work left to do is calling for trible i would think
[12:02:15] <anonimasu> if it dosent work well enough i'll nitride harden them and machine to final size +/- a few um
[12:02:26] <anonimasu> before that
[12:15:23] <MarkusBec> Loetmichel, ReadError I have vfd from donfoss with current vektor controll
[12:16:03] <Loetmichel> danfoss?
[12:16:11] <MarkusBec> ja
[12:16:57] <ReadError> how hard is it to integrate the VFD with EMC ?
[12:17:04] <MarkusBec> http://www.danfoss.com/Germany/BusinessAreas/DrivesSolutions/Frequency+Converters/VLT+AutomationDrive+FC+300.htm
[12:17:10] <Loetmichel> hmmm, btw: is that CNC route now yours or still lilalinux'?
[12:17:25] <MarkusBec> 50%
[12:18:13] <Loetmichel> ReadError: near to noting, two portpins for left and right and optionally a PWM pin wit r and C for spindle speeed control
[12:18:36] <MarkusBec> If i have time I will use modbus
[12:22:09] <ReadError> would i be better off with a router+superpid?
[12:22:57] <MarkusBec> superpid?
[12:26:02] <ReadError> http://www.vhipe.com/product-private/SuperPID.htm
[12:29:09] <MarkusBec> modbus will work with emc
[12:29:34] <MarkusBec> PWM out too
[12:58:52] <jeeves_moss> coudl someone here reccomend a good home machinist channel? I know this is for CNC, but a quick google didn't reviel anything
[12:59:19] <IchGuckLive> here you are right
[12:59:23] <IchGuckLive> jeeves_moss:
[12:59:33] <IchGuckLive> continent Europ or USA
[13:00:19] <jeeves_moss> Canada
[13:00:42] <jeeves_moss> right now, it dosen't matter. I'm just looking for advice on how to properly bore a blind hole without breaking the cutter
[13:00:56] <archivist> carefully
[13:01:23] <jeeves_moss> lol, thanks for the update
[13:01:27] <archivist> putting a rigid stop would help
[13:02:08] <archivist> and listen to the cutter
[13:02:21] <jeeves_moss> I was thinking of setting up the mill so that the Z axis would have a hard stop at the depth I wanted (first put the bar in and "bottom it out" without the mill running, then move the cutter the the center, and pull it down to the stop)
[13:03:12] <jeeves_moss> the hole needs to be finished to 1.125, so I was thinking of center drilling it with a 3/8, then use a 2 flute 1" end mill to "get it there", then bore it out the final 0.125
[13:03:18] <archivist> mill... bore a blind hole would normally imply lathe :)
[13:04:14] <jeeves_moss> lol, naaa. I'm doing this the hard way. this dumb sterling engine is starting to make my head hurt.
[13:04:53] <jeeves_moss> and the old 10" lathe I have moves around a lot. it's only good for rough stuff at the size of the hot cap I'm making. someone sudgested that I make up the hot cap from flat stock, and some pipe
[13:05:21] <archivist> do you have a rotary table
[13:05:33] <jeeves_moss> and since I'm a computer engineer, my first idea was to just CNC this mess. But I needed a challange.
[13:05:43] <jeeves_moss> and yes, I have a rotary table
[13:06:13] <Jymmm> Want a challenge? duct tape and bailing wire.
[13:06:30] <jeeves_moss> lol. that's how most of my networks are held togethere
[13:06:35] <archivist> you can use smaller cutters and helical bore using the rotary
[13:07:31] <jeeves_moss> this is what I found on-line so far
http://www.jjjtrain.com/vms/lathe_boring/lathe_boring_04.html
[13:09:18] <jeeves_moss> well, since I can't get into the shop today, it'll have to be Monday.
[13:09:22] <jeeves_moss> thanks again for your help
[13:09:29] <archivist> for milling a bore on a manual machine, a lot would have used a boring head after some clearance
[13:10:21] <jeeves_moss> next quick question
[13:11:22] <anonimasu> jeeves_moss: usually you just bore it to the final depth(with great care) no special tricks to it
[13:11:25] <jeeves_moss> if I have a single peice of cold rolled steel that I've got 3 peices from on the band saw, can I clam all of them side by side in the vice on the mill and fly cut the tops of them flat, or will they chatter around when the cutter hits them? I'm just looking to make this as quick as possible
[13:11:51] <anonimasu> they'll most likely chatter
[13:12:14] <archivist> I bet they wont grip well
[13:12:30] <jeeves_moss> even though they'd be hammered down flat to the bottom of the vice? and they were all cut from the same bar stock?
[13:12:31] <anonimasu> one trick would be to put a shim between of something compilant...
[13:12:43] <anonimasu> yeah
[13:12:45] <jeeves_moss> they're 1.5" sq stock
[13:13:19] <jeeves_moss> damn it. so what should I use for shim material? as I said, I want to flat them off so one end is square, then I can flip 'em and mill them ALL the the same height
[13:13:52] <anonimasu> or you can do them all in a series operation, where you cut the top off and just swap part and hammer them down
[13:14:40] <jeeves_moss> my concern with that is that if I don't get them totally hammered down, they'll be different heights. I tried that with the first set and they're all out by 7-10 thou
[13:14:55] <anonimasu> a strip of thin aluminium sheet would work.. anything that gives you a few 0.01mm's..
[13:15:04] <archivist> 7-10 thou is operator error
[13:15:34] <anonimasu> yep
[13:15:43] <jeeves_moss> I think I have some thin strips off of some scrap. I'm just trying to reduce it as much as possible. (being a computer tech by trade makes you a "nit picker")
[13:16:02] <archivist> look at the crap you left in the bottom of the vice
[13:16:24] <jeeves_moss> I blew it out before I put it in, and wiped it and the chunks off with a rag first
[13:16:38] <archivist> and the burs on the bar?
[13:16:39] <anonimasu> what vise do you have?
[13:16:48] <jeeves_moss> I think I didn't have the vice tight enough when I hammered them down and they bounced.
[13:16:50] <Tom_itx> make sure the vice isn't lifting the side up
[13:16:54] <jeeves_moss> I can't remember the brand.
[13:17:02] <anonimasu> is it a machine vise/no lift one
[13:17:04] <anonimasu> or a drill/mill vise?
[13:17:11] <archivist> a bad vice lifts the work
[13:17:15] <Tom_itx> the moveable side will lift on some
[13:17:16] <Tecan> http://www.youtube.com/watch?v=_OkWiweBs6w << EPIC Mini Guns...That Fire Real Bullets
[13:17:18] <jeeves_moss> I know it has KKK on the back. And it's a mill vice.
[13:17:20] <Tom_itx> bad bad bad for machining
[13:17:26] <Tom_itx> kurt are best
[13:17:28] <Tom_itx> etc
[13:17:39] <jeeves_moss> Tecan, do you know if there are plans out there for that?
[13:18:02] <anonimasu> I have a vertex one from taiwan it works decent
[13:18:06] <Tecan> i wouldnt know how to make the bullets
[13:18:07] <jeeves_moss> we wrote "My vice is that I'm racist" on the back of it.
[13:18:11] <Tecan> no sorry
[13:18:34] <jeeves_moss> anonimasu, and it's heavy as f**k.
[13:18:40] <anonimasu> you can put a indicstor on top of the vise and see how the movable jaw go when you tighten it
[13:18:41] <Tom_itx> as it should be
[13:18:43] <Tecan> i immagine it would be the real parts just scaled down and less of them ?
[13:19:28] <jeeves_moss> anonimasu, the tool and die maker at the shop hasent complained about it yet.
[13:20:10] <anonimasu> that dosent say anything.. experienced machinists usually have a way to make things work out good :)
[13:20:56] <jeeves_moss> well, tomorrow's job is to get those hot caps milled, bored out, and drilled. then to get the cold ends drilled and dressed to the proper height. that should take the better part of a day
[13:21:16] <anonimasu> I'd change with you I dont want to make shafts :D
[13:22:30] <jeeves_moss> anonimasu, actually........ That's also on my list tomorrow. I have to figure out the tempermental CNC lathe. No one has been able to get it to work. The owner had purchased it knowing it had "problems". So far, I've got mad enough that I ripped out the controller and spent a few weeks fixing cold solder joints and rewiring it since the wire was frayed.
[13:22:44] <anonimasu> what controller was it?
[13:23:19] <jeeves_moss> there isn't any markings on the covers on the boards, and the control panel says Func.
[13:23:25] <anonimasu> fanuc?
[13:24:02] <jeeves_moss> yea. something like that
[13:24:16] <jeeves_moss> I think what happened was someone tried to "fix" it before and mangled it
[13:24:21] <anonimasu> it's weird for the old ones to break..
[13:25:29] <jeeves_moss> as I said. it looks like someone was in there with sidecutters. I don't think the thing actually "broke" per se, but it was more like it suffred the ham fisted attempts of someone
[13:26:17] <jeeves_moss> I kind of feel sorry for it. But, now that we have the proper software for it, the owner is tinkering.
[13:26:41] <anonimasu> got a parameter backup?
[13:26:53] <jeeves_moss> I'm not sure what that means
[13:27:11] <anonimasu> there's parameters for thoose lathes, some which cant be backed up by data transfer
[13:27:20] <anonimasu> and if you dont have them you are in for alot of pain
[13:28:12] <anonimasu> (if you ever lose them)
[13:28:18] <jeeves_moss> oh god. I have a feeling that this is going to be a big broken mess!
[13:28:21] <anonimasu> like backup battery failing.
[13:28:33] <anonimasu> (they have to be replaced with power on)
[13:28:51] <anonimasu> good machinebuilders store them tho.
[13:29:00] <jeeves_moss> oh shit. yea, that's going to be written on the inside of the controller cover.
[13:29:20] <anonimasu> I spent like 3 months or tinkering with my lathe to cut a part on it
[13:29:46] <anonimasu> simply to get the parameters read out from paper tapes and getting all options and all pmc(stuff you cant backup) back, from a similiar lathe
[13:30:28] <jeeves_moss> is it docummented somewhere on-line if it gets lost?
[13:30:32] <anonimasu> no
[13:30:51] <anonimasu> best luck is to look for some shop with the same machine close in serial number
[13:31:08] <anonimasu> if it happens and contact the machine builder
[13:31:40] <jeeves_moss> ok. good to know. I'll let him know when I go in tomorrow before he starts messing too much
[13:31:45] <anonimasu> a fanuc tech can fix it too(comissioning everything again) and reading the plc to see what timers/counters/shit
[13:32:09] <anonimasu> atleast you should write the pmc parameters down and try to see if you have a copy of the other parameters(or the pmc data too)
[13:32:15] <anonimasu> before you disconnect it and start messing
[13:32:35] <anonimasu> fanuc has free phone support atleast over here
[13:32:55] <anonimasu> but they dont know much of ancient controllers
[13:33:33] <anonimasu> if you have a parameter backup and backup of the pmc stuff(the plc data) you are pretty safe
[13:33:37] <jeeves_moss> ok, thanks for the help. hopefully tomorrow I can get this engine parts done tomorrow. then I can go back into my little "hole" I have in the back corner of the shop to play with the lathe. That's about the only thing I'm good at.
[13:33:51] <anonimasu> my lathe arrived with the control stuck, so i had to nuke all settings to get it running
[13:34:43] <jeeves_moss> that would really suck. (not that I've ever had to do it, but I know computers, and how much I hate them after 17 years)
[13:35:12] <anonimasu> lathes are temperamental at best and so is computers.. now imagine :D
[13:36:11] <jeeves_moss> lol. I've got a network attached storage server with 12Tb of space on it that is currently rebuilding the array after a failed disk. just under 36 hours now and still chewing
[13:42:50] <jeeves_moss> anonimasu, thanks again for the info. I'm off to fight with this NAS. apparently the e-mail server hasn't been able to backup in almost 3 weeks
[13:49:15] <Tecan> would a replica machine gun lathed out hold up to rapidfire ?
[13:49:58] <Tecan> there's no special sleevs or anything just porting righ t?
[13:51:18] <alex4nder> Tecan: the question is: would your wallet hold up to a BATFE criminal suit?
[13:53:25] <Tecan> no probably not, was just wondering the feasability of it being reliable
[13:54:26] <Tecan> the quality of the metal
[13:55:33] <r00t4rd3d> i have all the parts for a new z axis cut then i change my idea :(
[13:57:50] <mrsun> http://www.bearingboys.co.uk/INA_Combined_Bearings_-_NKIA-1772-c what do you think about those for spindle bearings? :)
[13:59:57] <Tecan> http://www.youtube.com/watch?v=cy5npsYuSb0 LOL copper pipe shotgun
[14:02:42] <mrsun> Tecan, well that soldering job wasnt the prettiest either :P
[14:05:25] <mrsun> i wouldnt trust that as far as i could throw it
[14:05:32] <mrsun> :P
[14:10:02] <Tecan> looks legit other than it could go off at anytime
[14:13:23] <Tecan> or the nail could come flying out
[14:31:12] <motioncontrol> Hi at all. one question , the cycle g81 is = g85 and G89 is = G82 because more cycle for the some fuction ?
[14:57:10] <JT-Shop> looks that way
[15:00:10] <anonimasu> mrsun: for the top floating one?
[15:03:08] <mrsun> anonimasu, huh ?
[15:03:11] <mrsun> about the bearing
[15:03:20] <mrsun> its a needle bearing combined with a angular contact bearing
[15:03:48] <mrsun> so it would be able to handle great loads in what is it called .. when pushed to the side like a spindle needs
[15:04:00] <mrsun> and still being held good top to bottom
[15:04:31] <anonimasu> radial it is your talking about
[15:04:52] <anonimasu> how small spindle are you building?
[15:05:06] <mrsun> anonimasu, was a thought only for both lathe spindles and milling spindles =)
[15:05:38] <anonimasu> they are usually angular contact ones for that
[15:05:44] <mrsun> but mostly i was thinking for a gah words slip me tonight .. rotational table ...
[15:06:00] <mrsun> anonimasu, ye but those are combined with needle bearings also or roller bearings maybe its called
[15:06:11] <mrsun> so should be able to take a heck of alot of radial load
[15:06:13] <anonimasu> angular contact roller bearings
[15:06:27] <anonimasu> :)
[15:06:34] <mrsun> http://www.bearingboys.co.uk/uploads/nkia%20combined%20bearings.png
[15:06:47] <anonimasu> they handle more load and you dont hae the same tolerance requirements for a shaft to fit them
[15:07:33] <anonimasu> im looking at making a spindle someday soon, but I'll ship the shaft to the hardener when I ship stuff from work, then turn the od and send it off to grind the id
[15:08:25] <anonimasu> mrsun: are you going to grind the shaft for thoose bearings?
[15:08:42] <mrsun> anonimasu, this was just a thought to about if it would be a good bearing to use
[15:08:46] <mrsun> im not making a spindle atm =)
[15:09:11] <anonimasu> it would, no doubt but the shaft requirements for thoose kind of bearings are not quite that simple to get at home
[15:09:41] <mrsun> what would be required of the shaft? :)
[15:10:07] <anonimasu> ah, i didnt see that they are with centers :D
[15:10:17] <mrsun> :P
[15:10:36] <anonimasu> tho, i'd go with angular any day, it's how every spindle pretty much is built nowdays
[15:10:47] <mrsun> anonimasu, but they are angular!
[15:10:49] <mrsun> and roller
[15:10:50] <mrsun> :P
[15:10:52] <mrsun> combined!
[15:10:56] <anonimasu> angular roller bearings
[15:10:58] <mrsun> wtfpwn bearings
[15:11:07] <mrsun> anonimasu, they are angular roller bearings
[15:11:10] <mrsun> .. :P
[15:11:14] <anonimasu> haha
[15:11:18] <mrsun> look at the drawing!
[15:11:37] <anonimasu> plus, I'd think you need a pretty close tolerance to not get thermal buildup in them
[15:11:53] <anonimasu> (for the shaft) if you want it dead concentric
[15:12:15] <anonimasu> they dont seem that cheap compared to angular contact(ROLLER) bearings either
[15:12:24] <anonimasu> atleast not for the bigger sizes
[15:12:36] <mrsun> but using those would be like using angular contact bearings, only you get a much stronger radial strenght as they are combines with the straight roller bearing
[15:15:22] * mrsun can hear how anonimasu is banging his head against the desk by now
[15:15:52] <anonimasu> actually im looking at how close a HSK taper needs to be machined(ground)
[15:21:53] <anonimasu> seems like finding a grinder that can do that is heavy.
[15:22:41] <anonimasu> I want to build a small 40k rpm spindle :D
[15:25:38] <mrsun> anonimasu, do it with the angle grinder ;)
[15:26:13] <anonimasu> no problem..
[15:26:21] <anonimasu> but I cant measure it.
[15:28:42] <anonimasu> err, correction nobody around this part of the world can probably.
[16:01:49] <mercuryrising> when i have paused linuxcnc, it seems like it doesn't factor the pause into the piece - my prints become misaligned when I pause (although, depending on the timing, it can work better or worse)
[16:02:11] <mercuryrising> should it be working correctly, or is the pause like an Estop (when you press it, it's likely done)
[16:09:18] <Icekiller> cough anyone got any 25 hiwin rails
[16:11:10] <DJ9DJ> gn8
[16:19:16] <ReadError> mercuryrising whats it do?
[16:19:24] <ReadError> when i pause and continue it works
[16:19:33] <mercuryrising> it works - but it is offset from where it should be
[16:19:44] <mercuryrising> after the pause point, all my layers are shifted
[16:19:57] <ReadError> backlash ?
[16:20:09] <ReadError> you using the pause button in linuxcnc?
[16:20:15] <mercuryrising> im not sure, it only happens that severely when i pause
[16:20:17] <mercuryrising> yes
[16:25:13] <mercuryrising> and it seems like it may be a result of what the print head is doing when I pause, as sometimes I can pause and it's completely fine, but other times it is shifted significantly
[16:25:37] <mercuryrising> it seems like when it's traveling faster, there is more of a shift
[16:27:58] <pcw_home> AFAIK, pause should not hurt the path, but your extruder needs to do the right thing (backup)?
[16:28:13] <ReadError> oh
[16:28:17] <ReadError> its a 3d printer ?
[16:28:22] <mercuryrising> yeah
[16:28:36] <ReadError> what controller board
[16:28:39] <mercuryrising> hobbycnc
[16:28:42] <L84Supper> the nozzles on repraps are toys
[16:28:52] <L84Supper> so don't expect much
[16:29:20] <mercuryrising> pcw_home: you mean retract?
[16:29:25] <L84Supper> hot melt glue guns with DC motors
[16:29:56] <pcw_home> Ooze prevention
[16:30:02] <mercuryrising> I don't really think it would be a nozzle issue, as my X/Y/Z are what is incorrect (they are commanding the extruder to 'incorrect' positions)
[16:30:35] <mercuryrising> let me take a picture of this so we're on same page
[16:33:12] <L84Supper> open loop steppers + who knows what, when you hit pause. Sounds like lots of slop in the mechanics, unless that stepper driver doesn't actually stop the motors.
[16:34:21] <mercuryrising> stop the motors as in shut them off?
[16:34:37] <mercuryrising> (cut power to them)
[16:36:59] <L84Supper> mercuryrising: is that what you are doing vs pausing?
[16:37:19] <mercuryrising> no, im hitting the pause button - the motors are still powered
[16:38:10] <L84Supper> is the hobbycnc board connected over USB?
[16:39:11] <mercuryrising> no, parallel
[16:40:05] <mercuryrising> http://imgur.com/AKRAliP
[16:41:02] <mercuryrising> i can see slop being the answer, instead of gradually slowing down from a fast speed, it quickly slows down
[16:41:23] <mercuryrising> is there any way to tune the pause parameters, or run some gcode or a script when I hit pause?
[16:42:32] <L84Supper> is there less play when moving at lower speeds and more play when moving at higher speeds?
[16:42:59] <mercuryrising> yes - when it's traveling faster and i pause it shifts more
[16:43:33] <L84Supper> what are you using for positioners? leadscrews? belts and pulleys?
[16:43:40] <mercuryrising> leadscrews
[16:44:55] <L84Supper> have you checked the lash with a dial/laser encoder or indicator?
[16:45:15] <Jymmm> pics or it never happened
[16:45:22] <L84Supper> heh
[16:45:48] <ReadError> http://www.youtube.com/watch?v=fyK-lYNJieI
[16:45:52] <ReadError> this homeless guy rocks
[16:45:56] <mercuryrising> no, how would you test it? pause it when it's running at different speeds and see how far it goes?
[16:46:06] <L84Supper> or TV News, excluding Faux/Fox
[16:48:59] <L84Supper> mercuryrising: most repraps are rickety toys that are full of play. It sounds like you'll have to figure out where there play is in your setup and adjust or replace the sloppy parts
[16:50:31] <mercuryrising> mine's probably just as rickety, but it's not a reprap :P
http://imgur.com/sxbNz
[16:51:57] <L84Supper> the dual drawer slides in the z-axis might be one area that has lots of play in the x and y
[16:52:46] <Jymmm> held together with duct tape and wondering way pause is misaligned?
[16:52:54] <L84Supper> for $100 more on ebay you could make that setup rock solid
[16:52:59] <Jymmm> s/way/why/
[16:53:27] <mercuryrising> ducttape is to hold the aluminum foil to shield the wires
[16:53:59] <mercuryrising> what would you change first L84Supper?
[16:55:47] <L84Supper> I'd need more pics. Under the table/stage as well. Assuming the lowest axis is X, What are you using for the Y-axis positioning?
[16:56:37] * Jymmm would toss everything that's on the table into the dumpster
[16:57:21] <L84Supper> Jymmm: not a recycling bin?

[16:57:55] <mercuryrising> thanks Jymmm, you give some sound advice
[16:58:09] <Jymmm> L84Supper: maybe, but that wiring has gotta go.
[16:58:46] <L84Supper> Jymmm: it keeps the commies from listening in
[16:58:56] <Jymmm> only in hat form
[17:00:43] <L84Supper> I have an article from a 1964 Scientific American that begs to differ
[17:00:49] <mercuryrising> i (stupidly) used unshielded wires, and the motor's current was interfering with the extruder motor (it would just click and clack around), it was supposed to be a temporary solution, but it's working pretty damn well at the moment (well enough where other things can change before I fix it, it's ugly, but it works)
[17:01:47] <L84Supper> mercuryrising: there are several things that need some work that all add up to having play in your system
[17:02:26] <L84Supper> and the pic kind of begs for some fun being poked at it
[17:02:32] <Jymmm> Toss on a dial indicator and see what happens.
[17:02:55] <L84Supper> wiring, wood, poor assembly and alignment etc etc
[17:03:42] <mercuryrising> :) i know, it's not the most glorious thing in the world
[17:04:13] <mercuryrising> so i get a dial indicator, and I just run around with it to see how far off stuff is?
[17:04:32] <L84Supper> get the wiring straightened out first, then get the indicator on everything
[17:05:00] <L84Supper> move things around by hand and you'll see where all the play is
[17:05:11] <Jymmm> measure backlash and varoius points, measure movement before/after pause, etc
[17:06:04] <ReadError> holy hot mess batman
[17:07:05] <mercuryrising> will this dial indicator work -
http://www.amazon.com/TEKTON-7169-0-1-Inch-Dial-Indicator/dp/B000NPPBVK/
[17:07:39] <mercuryrising> or is there one that's way better for a similar price (<$30)
[17:08:10] <mercuryrising> you guys might not be the best to ask for advice on the cheaper stuff...
[17:08:29] <ReadError> http://www.amazon.com/gp/product/B0043F779K/ref=wms_ohs_product
[17:08:31] <ReadError> thats what i got
[17:08:36] <L84Supper> yeah, cheap tends to be cheap
[17:08:37] <ReadError> got decent reviews, works good
[17:08:46] <Jymmm> http://www.amazon.com/Dial-Indicator-Magnetic-Base-Point/dp/B002YPHT76/ref=pd_cp_hi_2

[17:09:21] <L84Supper> lots of Germans in China
[17:09:32] <ReadError> http://www.amazon.com/gp/product/B004EHHPDU/ref=wms_ohs_product
[17:09:36] <ReadError> thats what i got as well
[17:09:38] <syyl> looks like 100% chinese..
[17:09:40] <syyl> :D
[17:10:03] <ReadError> hey, it works ;)
[17:10:56] <L84Supper> the filament extruded by repraps are pretty big compared to +-25um that that indicator should be capable of
[17:11:58] <L84Supper> he's got ~0.5mm or more of play now
[17:14:28] <Jymmm> He's not measuring distances as much as differences.
[17:17:21] <L84Supper> this is the reason I just can't bear spending any time in the reprap channels
[17:20:57] <L84Supper> DIYers that want to build precision machines that don't know which end of a screwdriver to hold, free and broken software, 20 somethings that know it all about engineering, materials science and polymer chemistry
[17:21:32] <alex4nder> L84Supper: haven't you heard? traditional machining is dead.
[17:24:36] <L84Supper> alex4nder: untraditional machining is where it's at
[17:25:20] <alex4nder> L84Supper: yah, but for some reason all of my parts look like they are built out of dried toothpaste.
[17:25:26] <alex4nder> still trying to figure that one out
[17:26:59] <L84Supper> maybe it is toothpaste
[17:27:41] <mercuryrising> thanks a lot for the help guys! time to go watch some (hopefully good) commercials
[17:30:14] <anonimasu> L84Supper: I woud not trust a $15 dial indicator for anything important
[17:31:20] <anonimasu> I have a "decently" cheap id gauge (150eur) and I still make plug gauges off the mitutoyo micrometer's off mine to double check with for anything higher precision..
[17:31:24] <anonimasu> go/no go gauges
[17:33:18] <skunkworks> pcw_home: you had a way to connect encoders to the 7i76 - using the 2 inputs? (say for a jog wheel?)
[17:44:33] <tjb1> ReadError: Got the SD card working
[18:50:16] <Jymmm> that was bad

[19:07:42] <ReadError> nah
[19:07:46] <ReadError> dont need one
[19:09:21] <tjb1> Do you even print from SD/
[19:14:09] <ReadError> nah
[19:15:15] <tjb1> Never had a problem? I can only get to 115200
[19:18:00] <tjb1> I think that may have been my problem on that bridge print
[19:18:06] <tjb1> The infill was so many small moves it couldnt keep up
[19:29:25] * Jymmm isnt impressed with the half time show
[19:31:40] <tjb1> A nice blonde in the back row
[19:32:10] <tjb1> Why dont they get like Five Finger Death Punch to do the halftime show
[19:34:29] <Jymmm> Heh, someone coping a feel
[19:37:02] <pcw_home> skunkworks: yes the 7I76 has the spindle encoder but it can also use 4 inputs for 2 MPG encoders
[19:39:04] <Connor> pcw_home: Can you use two encoders on the 7i76 ? One for Spindle, and one for a servo type setup ?
[19:39:21] <pcw_home> No
[19:41:06] <Connor> Can't use 3 Digital I/O's straight into linuxcnc ?
[19:41:44] <pcw_home> Well there are a lot of options (use other 5i25 connector for more encoders)
[19:42:21] <pcw_home> I guess you could use the field IO but only for very slow encoders
[19:42:51] <pcw_home> But if you have another servo channel how do you drive it?
[19:43:04] <Connor> I don't have one yet.. probably be a while.
[19:43:36] <Connor> Dunno, Just asking questions. Was thinking just a PWM speed controller with encoder feedback to linuxcnc
[19:43:43] <pcw_home> if you have a step/dir with feedback setup a 5I25/7I85S is probably a better option
[19:44:12] <pcw_home> (or PWM/DIR)
[19:44:53] <pcw_home> or just use the other 5I25 connector with or without a breakout
[19:45:02] <Connor> It'll be a while.. I'm still in parport land so to speak.. the only encoder I have is on my spindle.. and will be very low count at this point.
[19:45:50] <Connor> I like the 5i25.. Just wish you could access both ports internally. I'll have to run a cable on the outside and loop it back in.. :(
[19:46:14] <pcw_home> You can also just use a 5I25 with whatever breakout boards you happen to have
[19:46:54] <Connor> I just have a standard C10 BOB.
[19:47:22] <Connor> I guess your multiplexing or something to get some of those inputs... ?
[19:48:09] <pcw_home> Yeah everybody complained about getting flat cables out of the case so we fixed that and now pepole want flat cables in the case again :-)
[19:48:40] <Connor> All of my stuff is in a single enclosure.
[19:49:21] <Connor> I guess other people have CPU in own case then enclosure for the electronics.
[19:49:58] <Connor> I guess I could go with the 7i43
[19:50:02] <pcw_home> the 7I76 has a mix of high speed I/O (the encoder input, the step/dir outputs, the serial links)
[19:50:02] <pcw_home> and low speed isolated field I/O done over a serial port
[19:50:14] <r00t4rd3d> http://i.imgur.com/bLKDTtz.gif
[19:50:20] <r00t4rd3d> i laughed
[19:50:30] <pcw_home> you could just use the internal connector
[19:50:47] <pcw_home> on your C10
[19:50:57] <Connor> how long you going to be around ?
[19:51:07] <Connor> want to loose the C10.. I could loose the C41 too..
[19:51:49] <Connor> since the 7i76 can do SCR 0-15 analog output.
[19:51:56] <Connor> need to eat. back in a few
[19:52:07] <pcw_home> me too
[20:26:34] <r00t4rd3d> tjb1 you can make shit on your n7 and save it in dxf format

[20:39:51] <pcw_home> dyna?
[20:48:02] <skunkworks> small vmc
[20:48:21] <tjb1> Printing a case for my LCD
[20:50:16] <Connor> pcw_home: Okay, so, explain the high speed/low speed on the 5i25.
[20:51:02] <Connor> I'm guessing the highspeed is direct to the 5i25, and low speed is muxed ?
[20:52:58] <Connor> and how much of a pain is it to switch from using the external to internal on the config side of linuxcnc ?
[20:55:35] <r00t4rd3d> anything hal related = pain.
[20:56:46] <tjb1> r00t4rd3d knows what is up
[20:56:48] <tjb1> Screw hal
[21:05:16] <skunkworks> Hal is awesome! Really - it is.
[21:12:57] <pcw_home> low speed = servo thread is serial

[21:13:26] <ReadError> on a 48x48
[21:13:37] <ReadError> nema34 is gonna be alot more expensive
[21:13:58] <skunkworks> what I need done? I am done. (well - done enough for me..)
[21:15:30] <skunkworks> tjb1: a bit of hal, A bit of C and a bit of ladder....

[21:15:55] <tjb1> What I need done :)
[21:16:16] <Connor> pcw_home: looking at pnpconf.. I see no way to use the other connector.. It's got the StepGen's coded for Connector 3..
[21:30:25] <pcw_home> Just do it in HAL
[21:32:29] <pcw_home> Its no more complicated than using different numbers for stepgens
[21:33:25] <skunkworks> pcw_home: it is actually Pete G - the guy that did the edm that they are talking about on the list..
[21:33:52] <pcw_home> Its a step/dir system?
[21:34:21] <skunkworks> He is using some rutex drives he as had for ever... (step/dir servos...) (yeck - I know)
[21:34:46] <skunkworks> but he loves them as he has never had issues with them
[21:35:45] <skunkworks> He lives about 20 miles from me.. (maybe 30)
[21:36:35] <skunkworks> It was funny - the first cnc fest I went to down in galsberg IL - I ran into him. first time I met him ;)
[21:37:23] <pcw_home> oops missing Dreams of the Emperor bbl
[21:39:50] <ReadError> is there a magical program that can place gcode around
[21:39:56] <ReadError> like if i make gcode for 1 part
[21:40:04] <ReadError> it can "clone" and offset it somehow
[21:44:03] <ktchk> reposition spindle and do a g54 retouch x and y start the program will mill the same part
[21:44:38] <ReadError> yea but if im cutting a 1.5"x8" part
[21:44:43] <ReadError> that would be a huge PITA
[21:45:02] <ReadError> i could try to do it in the CAM software
[21:45:12] <ReadError> just wondered if there was a better way
[21:46:18] <ktchk> dxf part file can be copy and do a cam of multi parts
[21:47:13] <ReadError> i would script this, but i suspect it would end in fail
[21:47:57] <ktchk> which cad cam software?
[21:48:24] <ReadError> ive been using hsmxpress
[21:48:47] <ktchk> can you edit the gcode?
[21:49:12] <Tom_itx> i can
[21:49:14] <Tom_itx> can you?
[21:49:29] <ReadError> yea
[21:49:48] <ktchk> add reposition x y and copy the gcode over
[21:50:01] <ReadError> could i make the entire code a subroutine
[21:50:10] <ReadError> and just move, call the same subroutine again
[21:50:19] <ReadError> sounds like a ghetto fix
[21:50:23] <Tom_itx> you could
[21:50:41] <Tom_itx> or change the fixture offset
[21:50:47] <Tom_itx> G54 etc
[21:51:34] <ReadError> yea, i was just hoping for an easier way
[21:51:42] <ReadError> but i guess i just need to do this once, and ill be okay
[21:57:56] <Connor> pcw_home: Yea, basic 3 axis step-dir + analog SCR spindle + encoder.
[22:34:49] <tjb1> I need 3 good inductive prox sensors, any reccomendations ?
[23:08:26] <L84Supper> http://www.youtube.com/watch?v=gem8m_Qdj8w&list=UU_VskFf9nosePUtxucxirRQ&index=11 too big for a machine controller UI, but it would be fun to demo this running EMC
[23:32:14] <Thetawaves> how do you guys rs485?
