[04:02:13] <furrywolf> well, if it's real, 4500lm for $15 is cheaper than 1600lm for $20...
[04:02:37] <XXCoder> yeah but then standard bulb shapem not that huge cyl
[04:02:58] <furrywolf> this part of my living room has two 1600lm led bulbs... got them at costco. think they were $18 or so.
[04:03:10] <furrywolf> they're standard bulb shape, but scaled up a non-trivial amount.

[04:04:32] <furrywolf> I have two fixtures with 2600lm CFLs in them, both of which could be brighter.
[04:04:48] <XXCoder> your costco also sell those 3500 lumen "forsecent lights" lights too>
[04:04:54] <XXCoder> $25 I think
[04:05:01] <XXCoder> I got 2 and plan to install em evenually
[04:05:16] <furrywolf> one lights up the walkway out front to the greenhouse, the other is an explosionproof fixture hanging over my batteries.
[04:05:40] <furrywolf> not sure what you mean. haven't seen any large fluorescent bulbs at costco here.

[04:07:53] <XXCoder> here has special city pay some money
[04:08:07] <XXCoder> https://i.imgur.com/blmWVrC.jpg
[04:08:12] <XXCoder> not 2 meter my mistake
[04:09:07] <furrywolf> I assumed you meant 48" and were just demonstrating how the metric system has poorly-sized units. :)
[04:09:20] <XXCoder> lol
[04:09:30] <XXCoder> I tend to use SI units sometimes
[04:10:08] <XXCoder> those lights are more "pure" than forsecent ones so you see better colors with those so I love it
[04:11:18] <furrywolf> they sound nice, but $40 for 38 watts is a lot more than a19 bulbs... costco here is currently selling 3-packs of 9w, 800lm bulbs for $10.99.
[04:11:47] <XXCoder> that would be same here if city didnt pay basically half of all led lights cost
[04:11:49] <furrywolf> that's $17 for the same amount of light
[04:14:43] <furrywolf> the other half of the living room has two 48t12 fixtures that I stuck up for extra light while working on projects... would like to LED them, but too expensive. I'll probably end up pulling them out and just sticking regular fixtures up.
[04:14:47] <XXCoder> good for garage though
[04:15:08] * furrywolf doesn't have a garage
[04:15:10] <XXCoder> I really need to put up two I own
[04:15:55] <furrywolf> also, are they good for a garage? spare bulbs are getting annoyingly expensive, they don't start in cold weather, the colors always suck...
[04:16:29] <XXCoder> yeah current lights there really suck - CFLs dont turn on fully for over minute
[04:16:32] <furrywolf> http://www2.costco.com/Browse/Product.aspx?Prodid=11981046&whse=BD_823&Ne=5000000%204000000&eCat=BD_823|97443|97470&N=4058751%205000105&Mo=0&No=0&Nr=P_CatalogName:BD_823&lang=en-US&topnav=bd also, looks like it's an entire replacement fixture, not just tube-shaped LED lamps.
[04:16:39] <XXCoder> it is
[04:16:46] <XXCoder> comes with its wire mounts
[04:16:57] <furrywolf> ... I'm quite sure you called it a tube light...
[04:17:17] <XXCoder> yeah looked like one, recently learned its whole fixture
[04:17:30] <furrywolf> bah, and only available in cool white.
[04:17:45] * furrywolf considers the longer part of the spectrum to be useful too
[04:18:55] <XXCoder> I guess costco just wanted those because cheap or something
[04:21:05] <furrywolf> http://www.ebay.com/itm/20W-SMD-2000Lms-4ft-T8-LED-Tube-3000-4500K-G13-2-yrs-USA-SELLER-Warranty-/221553819913 I thought you were talking about those, when you said tube lights
[04:22:18] <furrywolf> "Double ended and Single ended tubes are require to bypass ballast if you are planning to install on the existing fluorescent tube fixture." ... that kinda defeats the point...
[04:23:52] <furrywolf> if I have to pull it apart and rewire, I might as well change the fixture.

[05:00:30] <Connor> You need to get some shims.. but, yes.. I did.. they were bored out too deep.
[05:00:38] <zeeshan> see im a bit confused
[05:00:45] <zeeshan> you know the black bushings?
[05:00:51] <Connor> yes.
[05:00:52] <zeeshan> [ | | ]
[05:01:00] <zeeshan> [ = black bushing | bearing
[05:01:13] <zeeshan> dont the black bushings preload the bearingd
[05:01:33] <zeeshan> when you tighten the square nut at the end
[05:01:37] <Connor> No.
[05:01:46] <Connor> because they're only on the inner race.
[05:01:47] <zeeshan> can you explain why not?
[05:02:13] * zeeshan tries to imagine
[05:02:14] -!- Flipp_ has quit [Remote host closed the connection]
[05:02:27] <Connor> the outer race contacts the bearing block. So, the bearings can move back and forth in the pocket.
[05:02:40] <zeeshan> ahhh
[05:02:42] <zeeshan> that makes sense!
[05:02:56] <zeeshan> i changed to a double ball nut
[05:03:00] <Connor> So, put shims between the bearings, or on the outside to take out the slack.
[05:03:01] <zeeshan> and i havbe the same amount of backlash
[05:03:09] <zeeshan> so i carefully measured the end play
[05:03:17] <zeeshan> and theres the same amount as the amount of backlash im getting
[05:03:22] <zeeshan> and whats weird is the backlash isn't constant.
[05:03:26] <zeeshan> sometimes its there, sometimes its not
[05:03:32] <Connor> Slip-n-stick
[05:03:58] steves_logging is now known as steve_stallings
[05:04:12] <zeeshan> did you preload the bearings
[05:04:13] <zeeshan> using the shim
[05:04:50] <Connor> You can adjust the preload if you have ENOUGH shim by tightening up the 4 screws on the face of the bearing block.
[05:05:00] <MacGalempsy_> i got a double ball nut
[05:05:49] <Connor> That's why I like bearing pockets that have a shoulder on the inside.. then the preload is handled by the main nut and no way you get lash from the bearings.
[05:06:44] <Connor> They really should supply some shims with those bearing blocks..
[05:06:45] <zeeshan> did you get these:
[05:06:55] <MacGalempsy_> dees nuts?
[05:08:26] <zeeshan> http://www.mcmaster.com/#standard-shims/=w4nf6b
[05:08:52] <Connor> Yup.

[05:09:23] <zeeshan> you didnt push the bushings
[05:09:25] <zeeshan> between the bearings?
[05:09:28] <zeeshan> i mean the shims
[05:09:29] <Connor> you only want the outer race contacting them.
[05:09:46] <Connor> Either way.. you just don't want the inner race to rub against them.

[05:15:22] <XXCoder> lol
[05:15:30] <MacGalempsy_> I work every day when on a stint. last year i went 109 days straigth
[05:15:41] <XXCoder> its "for now" or do you plan to stay on
[05:16:02] <MacGalempsy_> been trying to get on days for a while, but since the industry is in a slump, I cant go making demands
[05:16:55] <MacGalempsy_> the only thing I could do to survive was plan every vacation on 1/1, so like 5 weeks on, then 10 days off
[05:17:16] <MacGalempsy_> by the time vacation comes, its like, IM GOING TO VEGAS

[05:57:07] <zeeshan> thats cool bobo_
[05:57:12] <zeeshan> Connor: this is so annyoing
[05:57:24] <zeeshan> i added a few steel shims right behind the 4 bolt cover
[05:57:28] <zeeshan> 15 thou worth
[05:57:37] <zeeshan> tightened it down, and still there is 1.5 thou backlash at the end of the screw
[05:57:42] <zeeshan> the way im measuring backlash is
[05:57:47] <zeeshan> by pull/pushing on the axis
[05:58:09] <renesis> is it consistent?
[05:58:56] -!- The_Ball has quit [Ping timeout: 256 seconds]
[05:59:03] <zeeshan> also what makes no sense is that i measured .754" between housing and outer race
[05:59:13] <zeeshan> and the lip is .755" on the 4 bolt cover
[05:59:18] <zeeshan> so i dont even know why i need a shim
[05:59:29] <zeeshan> regardless, i put a 15 thou shim in there and nothing changed
[05:59:38] <zeeshan> renesis: yea
[06:00:00] <renesis> so run some cycles, measure it again, if it doesnt change, program it in
[06:00:12] <zeeshan> connor wake up!! :P
[06:00:46] <zeeshan> renesis: programming backlash isnt the best fix
[06:01:08] <renesis> right youll probably want to track it
[06:01:58] <renesis> im so out of butane
[06:02:13] <renesis> i dont think camping butane fits the torch
[06:02:32] <Connor> That's odd.
[06:02:41] <zeeshan> yea dude
[06:02:42] <zeeshan> im confused
[06:02:50] <zeeshan> i must be doing something wrong
[06:02:59] <Connor> Bearings Back To Back? Or Back to front? or Front-to-Front ?
[06:03:52] <zeeshan> hm
[06:03:57] <Connor> Should be back to back
[06:04:03] <zeeshan> are you serious
[06:04:03] <zeeshan> lol
[06:04:08] <Connor> YES
[06:04:12] <zeeshan> wait lemme think.
[06:04:16] <Connor> IF They're AC bearings..
[06:04:24] <Connor> and you have them wrong.. they won't work right.
[06:04:41] <Connor> They won't handle load in one direction.
[06:05:34] <zeeshan> im trying to think how i have them
[06:05:45] <zeeshan> i know theyre opposite to each other
[06:05:51] <zeeshan> like left bearing is reverse of right
[06:06:06] <zeeshan> its kinda hard to tell which is front on th ebearing
[06:06:08] <zeeshan> and which is back
[06:07:34] <Connor> The end with the larger looking space is the back.
[06:08:07] <zeeshan> is that face supposed to face the 4 bolt cover?
[06:08:18] <Connor> yes.

[07:05:16] <zeeshan> hey connor
[07:05:46] <zeeshan> the end w/ the larger opening
[07:05:49] <zeeshan> wasn't facing the 4 bolt cover
[07:06:09] <zeeshan> [large | | large]
[07:06:15] <zeeshan> er
[07:06:19] <zeeshan> [large small small large]
[07:06:22] <zeeshan> is the arrangement now
[07:06:40] <zeeshan> still have 2 thou backlash
[07:06:46] <zeeshan> in that housing :/
[07:08:31] <LeelooMinai> I can see that GS2 also has some analog input for potentiometer, some forward/reverse switches, but also Rj012 Serial Comm Port. So now I am not sure - how should I connect this thing to the Mesa/Linuxcnc?
[07:13:00] <Connor> That's face to face I think zeeshan
[07:13:16] <zeeshan> well back to back
[07:13:17] <zeeshan> and face to face
[07:13:21] <zeeshan> should both support the loads?
[07:13:39] <Connor> Something strange about face to face application.. everyone says to do back to back.
[07:13:47] <zeeshan> well it was back to back before
[07:13:48] <zeeshan> :)
[07:13:49] <Connor> but.. the bearings should not be moving inside the pocket at all.
[07:13:57] <zeeshan> i cant tell whats moving to be honest
[07:14:12] <zeeshan> i can feel a bit of rock
[07:14:18] <zeeshan> with the two bearings on the shaft
[07:14:22] <zeeshan> (its almost a press fit)
[07:14:28] <zeeshan> so if i dont bolt down the fixed support
[07:14:33] <Connor> can you take the dust sleeve off?
[07:14:36] <zeeshan> i can feel the fixed support slightly wobbling
[07:14:47] <zeeshan> i thinkso
[07:14:51] <zeeshan> it just pushes out i think
[07:15:16] <Connor> You might want to do that.. Those things can cause things to feel tight when they're not..

[07:15:56] <Connor> if you have end to end play.. it has to be because the shims aren't enough, or not touching the outer race and the front of the bearing cover.

[07:16:52] <Connor> back when I didn't know sh!t
[07:17:04] <zeeshan> you saw my commebnt about
[07:17:20] <zeeshan> me measuring .764 from outer race to fixed support with 4 bolt cover removed
[07:17:26] <zeeshan> and the lip on the 4 bolt cover being .766"
[07:17:33] <zeeshan> thats a 2 thou interference
[07:17:44] <zeeshan> and on top of that i have a 10 thou shim in there right now
[07:17:49] <zeeshan> 12 thou interference
[07:17:53] <zeeshan> i wonder if the bearings are garbage
[07:17:56] <zeeshan> and just have tons of play in them
[07:18:04] <archivist> bearings in backwards?
[07:18:16] <zeeshan> archivist: i tried both front to front
[07:18:18] <zeeshan> and back to back
[07:18:23] <zeeshan> both give 2 thou backlash
[07:18:57] <archivist> are they even the correct type
[07:19:02] <zeeshan> haha
[07:19:06] <zeeshan> theyre those ball bearings
[07:19:09] <zeeshan> not taper roller bearings
[07:19:13] <zeeshan> the offset kind of ball bearings
[07:19:32] <zeeshan> http://image.slidesharecdn.com/angularcontactballbearingsid-13492380965704-phpapp02-121002232330-phpapp02/95/angular-contact-ball-bearings-id-6-728.jpg?cb=1389719876
[07:19:34] <Connor> They should be Angular contact bearings if you got them from LMB2008
[07:19:35] <zeeshan> (what connor posted)
[07:20:18] <archivist> yes but those for the job come as matched pairs and have the angular contact part number
[07:20:20] <Connor> Nut -- Bushing -- Bearing : SHIM : Bearing -- Bushing -- Should of ball screw
[07:20:37] <zeeshan> what
[07:20:40] <zeeshan> the shim goes between the bearings?
[07:20:46] <Connor> should of ball screw shoulder of balls crew
[07:20:56] <zeeshan> i have
[07:20:56] <Connor> I would try it between them.. yes.
[07:21:10] <Tecan> nvidia
[07:21:11] <zeeshan> nut bushing shim bearing bearing bushing should of screw
[07:21:24] <Tecan> oops
[07:21:28] <archivist> needs to be in the right place to suit the arrangement
[07:21:51] <Connor> and it should be the same diameter as the OD of the bearing.
[07:22:01] <zeeshan> connor iuse grease
[07:22:02] <zeeshan> and shim stock
[07:22:11] <zeeshan> and cut out a semi circle and put em in there
[07:22:15] <zeeshan> ill get real shims tomorrow
[07:22:17] <zeeshan> i was just trying it out
[07:22:34] <zeeshan> archivist: if you see that image with the bearings
[07:22:38] <archivist> semi circle !
[07:22:40] <zeeshan> back-to-back and face-toface
[07:22:41] <Connor> and should have a ID larger than the outside OD of the inner race.
[07:23:12] <Connor> so the inner race doesn't touch the shim.
[07:23:23] <zeeshan> wouldnt placing the shim in the middle of the bearings have the same effect in both cases?
[07:23:25] <zeeshan> Connor: yes
[07:23:55] <Connor> Maybe.
[07:24:03] <archivist> shim inner only on back to back
[07:24:29] <archivist> shim outer face to face
[07:24:46] <zeeshan> how do you tell whats back and whats front
[07:24:47] <zeeshan> ! :P
[07:24:53] <zeeshan> i know connor said the larger gap
[07:24:56] <Connor> again, this is why I like bearing pockets with a inner shoulder.
[07:25:08] <Rab> zeeshan, look at the bearings.
[07:25:11] <zeeshan> is back
[07:25:12] <Swapper> zeeshan: i have the exact same problem :)
[07:25:14] <archivist> you can shim inner face to face if you use a small dia shim for inner race dia only
[07:25:23] <zeeshan> swapper hehe
[07:25:26] <zeeshan> we can help each other! :P
[07:25:42] <Connor> Also, the writing is typically on the FACE not the back.
[07:25:44] <Swapper> yea, but i havent found a good way to realy be shure whats "front"
[07:26:12] <Connor> Look at the bearing and see if the balls have more contact on the inside shoulder of the bearing.
[07:26:14] <archivist> it is visible on a proper bearing
[07:26:28] <archivist> or should be
[07:26:40] <zeeshan> i shoulda taken a pic
[07:27:12] <archivist> that arrangement drawing makes the inner/outer shape plain to see
[07:27:20] <zeeshan> http://www.nbcgroup.co.uk/assets/image/General%20bearing%20photos/Angular%20contact%20brgs.jpg
[07:27:20] <Connor> and it's important to get this right.. if you don't.. you can separate your bearings.
[07:27:23] <zeeshan> it looks like that
[07:27:54] <Connor> take a picture of your own.. one up and one down.
[07:28:12] <archivist> turn it round does it look different, measure too
[07:28:19] <Connor> http://www.ivdc.com/cnc/BallScrew/1.jpg
[07:28:26] <Connor> OKay.. that's my bearings..
[07:28:42] <Connor> The one on the left.. is showing it's BACK, the one on the right.. is the FRONT
[07:28:52] <Swapper> good picture1
[07:28:54] <Swapper> !
[07:29:02] <zeeshan> connor
[07:29:04] <zeeshan> mine looks exactly like that
[07:29:11] <zeeshan> the left one is the "back"
[07:29:20] <zeeshan> so its like this:
[07:29:33] <Rab> zeeshan, in that pic, notice that the inner race appears thicker than the outer race, and protrudes further. That's a good indication that the axial load goes toward the bearing, away from the camera.
[07:29:43] <zeeshan> nut bushing shim back front front back bushing screw
[07:30:07] <archivist> two dead men got up to fight back to back the faced each other, drew their swords and shot each other
[07:30:23] <zeeshan> rab that makes sense
[07:30:29] <zeeshan> ive never worked with angular ball bearings before
[07:30:33] <zeeshan> its obvious with taper bearings

[07:31:36] <Connor> NUT-- Bushing -- [FRONT-BACK] -- SHIM -- [BACK-FRONT] -- Bushing -- Shoulder of Screw

[07:32:32] <zeeshan> the shim needs to be on the id
[07:32:42] <archivist> and there is the point, is the outer (face to face) adjusting the preload or inner (back to back)
[07:32:46] <Rab> zeeshan, the purpose of the shim is to preload the bearings. Think about where the thrust is transmitted in the bearing surfaces, and how it needs to be preloaded to remove play.

[07:33:50] <zeeshan> looks like the force on the right <----
[07:33:58] <zeeshan> gets supported by the left bearing
[07:34:01] <Rab> Correct.
[07:34:02] <Connor> IN a Back To back setup, you want the shim in the middle.. same OD as the Bearings.. with a ID larger than the OD of the inner race so it doesn't rub.
[07:34:15] <zeeshan> connor yes ill do that

[07:34:34] <zeeshan> face-to-face doesnt look good

[07:35:39] <Connor> Have they not covered this in school?
[07:35:48] <zeeshan> no
[07:35:52] <zeeshan> not angular ball bearings
[07:35:54] <Swapper> i have a shim in the middle supporting the outer races, that would make my setup face 2 face?
[07:36:07] <zeeshan> just learned that they are crap
[07:36:11] <zeeshan> in comparison to a taper roller bearing
[07:36:11] <Connor> Swapper: Back to back
[07:36:21] <archivist> good for the job they do
[07:36:33] <Swapper> Connor: but aint the front the load taking part?
[07:36:36] <Connor> Treat AC as Taper roller bearings for the most part.
[07:36:39] <Rab> zeeshan, consider than they're conceptually identical to a tapered roller bearing.
[07:36:47] <zeeshan> rab not really
[07:36:57] <zeeshan> the contact area very differnt
[07:37:05] -!- ashcan [ashcan!~robert@navsoft.plus.com] has joined #linuxcnc
[07:37:05] <archivist> even car wheel bearings are AC these days
[07:37:29] <Connor> zeeshan: They transmit the axial load in the same way.
[07:37:41] <zeeshan> yes
[07:37:45] <Connor> just more surface area on Tapers, thus more friction..
[07:37:45] <zeeshan> but im sayign the contact area is different
[07:38:15] <Rab> zeeshan, that's not relevant to understanding the operation of the bearing.
[07:38:19] <zeeshan> i wouldn't be using an ac bb for differentials! :P
[07:38:29] <Rab> It just means the roller bearing has more load capacity.
[07:38:56] <zeeshan> rab
[07:39:03] <Connor> Anyway.. AC Bearings 101 Class is over.. Time for bed.
[07:39:07] <zeeshan> it wasn't obvious to me how the ac bearing was supporting load
[07:39:08] <zeeshan> http://catalog.ubx-usa.com/wp-content/uploads/2009/04/roller-tapered-metric.jpg
[07:39:12] <zeeshan> this is obvious :)
[07:39:24] <zeeshan> haha connor
[07:39:26] <zeeshan> thanks for the help
[07:39:32] <Rab> zeeshan, this might help:
http://highspeedtechnologies.com/dev/wp-content/uploads/2014/03/14-PRELOAD-FORCES.jpg
[07:39:57] <Connor> zeeshan: Same thing.. just replace the roller with ball.. supports the load in the same exact way.
[07:41:50] <Connor> I found out one day why they are like that.. I tried to take a AC bearing off of my spindle and it came apart because I was putting the load on the outer race trying to get it off.. (because I couldn't grip onto the inner race).

[07:42:39] <zeeshan> yes
[07:42:42] <Connor> I had to grind the inner race off.. it was the exact diameter of the should on the spindle.
[07:42:45] <zeeshan> just to check if i actually undferstand this
[07:42:51] <zeeshan> http://image.slidesharecdn.com/angularcontactballbearingsid-13492380965704-phpapp02-121002232330-phpapp02/95/angular-contact-ball-bearings-id-6-728.jpg?cb=1389719876
[07:42:55] <zeeshan> to preload the very right bearing setup
[07:43:03] <zeeshan> you'd need a shim in the middle for the ID race only
[07:43:17] <Connor> correct
[07:43:19] <zeeshan> and you' dneed a shim on od's
[07:43:24] -!- ashcan has quit [Quit: Ex-Chat]
[07:43:25] <zeeshan> on the outside faces
[07:43:33] <zeeshan> equal size shims
[07:43:45] <Rab> Why would you need that?
[07:44:17] <zeeshan> im thinking
[07:44:21] <zeeshan> there will be gap otherwise
[07:44:36] <zeeshan> assuming the bearings are 10mm wide
[07:44:42] <zeeshan> and the gap is 21 mm
[07:44:55] <zeeshan> if you shimmed the inner race for 1mm
[07:45:15] <zeeshan> theres still nothing supporting the outer race
[07:45:19] <zeeshan> theres still a total of 1mm gap
[07:45:23] <Connor> WAIT

[07:45:55] -!- georgenz has quit [Ping timeout: 252 seconds]
[07:46:13] <Connor> The preload comes from tighing up the ballscrew jam nuts.. it applies force to inside races.. squezing them together.
[07:46:42] <Connor> the shim does nothing for preload.. it just keeps the bearings from moving back and forth.. (on a back to back setup)
[07:46:48] -!- radish has quit [Ping timeout: 252 seconds]
[07:47:20] <Connor> in face-to-face.. the preload is handled on the outside race.
[07:47:35] <zeeshan> ah
[07:47:52] <Connor> and your limitted to the amount of preload, because the innner races will touch.
[07:48:40] <zeeshan> okay so you do want back to back
[07:49:02] <archivist> depends if the preload it outer or inner
[07:49:13] <zeeshan> preload is inner
[07:49:18] <Connor> yup. and if you shim in the middle.. it gives you a bit more space to preload.
[07:49:22] <archivist> then outer shim
[07:49:38] <archivist> for clamping
[07:49:38] <zeeshan> its so weird
[07:49:41] <Rab> zeeshan, re your dismissal of balls as crap vs tapered roller...I suspect balls have lower friction losses, and so might perform better at very high speeds.
[07:49:53] <zeeshan> i can see shimming taper bearings no problem
[07:49:59] <zeeshan> bb ac weird :)
[07:50:29] <zeeshan> Rab: im thinking of transmission applications
[07:50:30] <zeeshan> for cars
[07:50:31] <Swapper> zeeshan: agree, getting more confused, wonder if all my ac are the wrong way :)
[07:50:55] <Rab> zeeshan, I'm thinking of CNC spindles.
[07:50:57] <Connor> It's enough to drive you crazy when you first do it..
[07:51:13] <Rab> But the big boys might use tapered roller bearings for all I know.
[07:51:17] <Connor> Rab: I changed my tapered ones out for AC for that very reason on my G0704
[07:51:28] <Rab> ahh
[07:51:49] <zeeshan> pretty sure high speed spindles use fancy ac bb's
[07:52:07] <archivist> side load and speed is a compromise between the two
[07:52:16] -!- radish has quit [Ping timeout: 256 seconds]
[07:53:57] <Connor> Well.. heck.. now I'm second guessing myself on this picture which way is which..
http://www.ivdc.com/cnc/BallScrew/1.jpg
[07:54:16] <zeeshan> im pretty sure
[07:54:18] <zeeshan> the right one
[07:54:21] <zeeshan> is front face
[07:55:01] <archivist> only if the outer clamp can provide the preload force
[07:55:13] <Rab> zeeshan, I think it's the opposite.
[07:55:25] <zeeshan> lol
[07:55:29] <zeeshan> !!
[07:55:36] <archivist> which makes me agree with Rab :)
[07:55:40] <Rab> Look at your diagram:
http://image.slidesharecdn.com/angularcontactballbearingsid-13492380965704-phpapp02-121002232330-phpapp02/95/angular-contact-ball-bearings-id-6-728.jpg?cb=1389719876
[07:56:03] <zeeshan> yea the outer race is thin
[07:56:05] <zeeshan> and inner is thicker
[07:56:06] <Rab> The outer race is thinner on the "face".
[07:56:20] <zeeshan> but the inner race is thinner on the back
[07:56:26] <Connor> yea.. the left is front the right is back..
[07:56:26] <zeeshan> but in his image theyr eboth thick! :P
[07:56:41] <zeeshan> well thats how i have them in right now
[07:56:47] <zeeshan> only thing wrong is the shim isn't in the middle of em
[07:56:49] -!- mhaberler [mhaberler!~mhaberler@extern-171.stiwoll.mah.priv.at] has joined #linuxcnc
[07:57:02] <zeeshan> i hope that fixes this annoying backlash nonsense
[07:57:02] <Rab> zeeshan, sure, but if you do a google image search for ACBs you'll see a lot are constructed with a symmetrical inner race.
[07:57:03] <Connor> Large gaps to the outside is back to back.
[07:57:05] <archivist> the outer is correct in the set of images
[07:58:58] * zeeshan needs to buy shims
[07:59:32] <Connor> I had to think back to my spindle.. and remembered that larger gaps were top and bottom.. and that was a back to back setup.
[08:00:19] <Swapper> my brain hurts
[08:00:48] <Connor> the back is the side where if load is applied to the inner race, it's transmitted to the outer race.. if you do it backwards the bearing will seperate.
[08:01:20] <zeeshan> yea
[08:01:25] <zeeshan> in your case the back is the left image
[08:01:28] <archivist> there is a book for home brew spindle making "Spindles Harpit Sandhu Special Interest Model Books Ltd 2008"
[08:02:36] <Connor> OKay. Bed time.

[12:28:52] <miss0r|shop> a bit slow. Waiting for UPS to come with a 3-axis kit i ordered. you?
[12:29:30] <MacGalempsy> just got off work. took the trash out without breaking my neck on the ice and in the mail was a solder sucker I got off ebay.
[12:29:53] <miss0r|shop> sounds like a pretty good start :)
[12:29:55] <MacGalempsy> spent most of the night wiring up the control panel on my machine
[12:30:38] <miss0r|shop> pics?

[12:32:09] <MacGalempsy> it took a while, but still dont have the power switch fully figured out
[12:32:41] <miss0r|shop> Might I reccomend some spiral-flex? :)
[12:33:27] <miss0r|shop> other than that I think it looks real nice.
[12:33:50] <MacGalempsy> that is an old pic
[12:34:11] <miss0r|shop> I just build this for work:
http://picpaste.com/pics/DSC_0036-tZooxgqr.1425298416.JPG
[12:34:14] <MacGalempsy> we moved since then. I am trying to trim cables as it goes ahead
[12:34:18] <miss0r|shop> it is part of a factory production line
[12:34:53] <MacGalempsy> I like how clean the wiring is
[12:35:20] <miss0r|shop> always a huge concern when I build stuff
[12:35:44] <miss0r|shop> functionality = unimportant, as long as it looks good :P
[12:35:52] <MacGalempsy> ikr?
[12:36:33] <miss0r|shop> ikr?
[12:36:42] <MacGalempsy> I know, right?
[12:36:47] <miss0r|shop> hehe yeah
[12:36:48] <MacGalempsy> heh
[12:37:06] <miss0r|shop> that mill of yours looks realy nice. It is a tool changer I am looking at?
[12:37:09] <MacGalempsy> are you a linuxcnc vet?
[12:37:38] <miss0r|shop> oh hoho no..
[12:37:38] <MacGalempsy> there is one in there. that is part of the reason the machine was selected
[12:37:59] <miss0r|shop> i've used it for a year or so. i'm no expert
[12:39:23] <MacGalempsy> at this point, the machine is working on 3 axes. I just installed the 4th axis the other night, but haven't tried it out yet
[12:39:43] <miss0r|shop> sweet. I am just thinking - how does it control the tool changer?
[12:40:14] <MacGalempsy> mechanically, or through the software?
[12:40:22] <miss0r|shop> I was thinking software
[12:40:38] <MacGalempsy> supposedly through the classic turret setup
[12:40:44] <MacGalempsy> havent got that far yet.
[12:41:15] <miss0r|shop> I am thinking I will safe that link of yours and look at it from time to time.
[12:41:15] <MacGalempsy> once the relays come in, I can control the pneumatic valves and motor
[12:41:51] <miss0r|shop> I love builds such as yours
[12:42:15] <miss0r|shop> it makes me feel insufficient about my own :)
[12:42:31] <MacGalempsy> the retrofit has been a great learning experience. plus I get to hang out in here and annoy everyone with noob questions
[12:42:49] <Swapper> you run mesa cards for that ?
[12:43:02] <MacGalempsy> yep.
[12:43:10] <miss0r|shop> hello Swapper o/
[12:43:29] <Swapper> hi :)
[12:43:34] <Swapper> 7i77 ?
[12:43:47] <Swapper> real nice little mill
[12:43:56] <MacGalempsy> 5i25, 7i77, 7i84.
[12:44:11] <MacGalempsy> I felt it was perfect for my workspace size
[12:44:13] <Swapper> ok, i run 6i25 + 7i77 my self
[12:44:19] <MacGalempsy> and the price was a steal
[12:44:32] <Swapper> where it working when you got it?
[12:44:54] <Swapper> its a real win to get all the goodies all done, enclosure and toolchanger
[12:44:57] <MacGalempsy> no. it was missing the controller card, so I had to reverse engineer the wiring, which took about 3 months
[12:45:10] <MacGalempsy> well, wiring and finding the bloody tech sheets
[12:45:11] <Swapper> ive built the enclosure for mine and its a pita
[12:45:50] <Swapper> so you use the original drives?
[12:46:12] <MacGalempsy> yep, the only things I removed so far are the original motherboards and one of the power supploes
[12:46:25] <MacGalempsy> got it tuned up to 0.0001"
[12:46:42] <miss0r|shop> that pretty goodf
[12:47:37] <miss0r|shop> it would not be possible for me to do better than 0.0004" in my build
[12:48:25] <MacGalempsy> thats still pretty dang good
[12:49:10] <miss0r|shop> i'm doing a CNC conversion on an Arboga u2508 - so lets see if it is even possible to that extend :)
[12:49:12] <MacGalempsy> my mission today is to call the tech line at the unit manufacturer and see if I can schmooze them into giving me their original PID values to see how it measures up
[12:49:13] <Swapper> is it linear ways on that?
[12:49:52] <MacGalempsy> http://www.machinetoolsonline.com/doc/benchman-xt-industrial-cnc-machining-centers-0001
[12:50:04] <MacGalempsy> there is the specs from the company
[12:50:25] <Swapper> Cast polymer, one-piece base and column
[12:50:26] <Swapper> nice
[12:50:57] <miss0r|shop> MacGalempsy: dare I ask what you've payed for it?
[12:51:03] <MacGalempsy> 5k
[12:51:31] <miss0r|shop> sweet. congrats on that

[12:57:26] <Swapper> anyone know what it would cost to get some plain sheet metal plasma/laser cut ?
[12:57:31] <Swapper> start costs and souch
[12:57:51] <Swapper> need to build me a coolant/chip filter tank
[12:58:14] <miss0r|shop> why not just buy a perforated sheet?
[12:58:25] <SpeedEvil> Collander.
[12:58:31] <SpeedEvil> And seive
[12:58:43] <Swapper> i meant for the whole tank
[12:58:54] <Swapper> not the filter part
[12:59:05] <SpeedEvil> You'll be making us using buckets look bad!
[12:59:08] <MacGalempsy> an old country sink would be a pretty good tank
[12:59:32] <SpeedEvil> There is very little reaon to plasma/laser cut it
[12:59:34] <Swapper> im using a "bucket" today but its flimsy and i get the pump cloged with chips
[12:59:38] <SpeedEvil> A jigsaw will work just fine
[12:59:46] <Swapper> i do have a plasma
[12:59:46] <SpeedEvil> And a file to tidy up
[12:59:48] <Swapper> but not cnced
[13:00:08] <SpeedEvil> Well, plasma it, and angle grinder to tidy up the edges to the line
[13:00:11] <Swapper> but then i have to get the mats for it
[13:00:28] <miss0r|shop> Swapper: how big does it need to be? I have a 20L tank w/pump laying around.
[13:00:31] <Swapper> and i where thinking to get the mats and the cut from the same place

[13:01:06] <SpeedEvil> expanded metal works just fine for chip filtration
[13:01:15] <Swapper> miss0r|shop: i have a sump that i think is 20l that came with the mill. And thats to small
[13:01:16] <SpeedEvil> rather than bothering with plasma or LASER
[13:01:56] <archivist> chip catching uses gravity too multiple containers with spillways
[13:02:05] <Swapper> i whant to make sections in the tank that allow for the chips that comes through to fall to the botom
[13:02:07] <archivist> no filter needed then
[13:02:14] <SpeedEvil> archivist: Well - it depends.
[13:02:33] <miss0r|shop> I have a problem with the drain I can't figure out. I have a 3/4" plastic 'garden hose' connected to nibble on the table, but it doesn't flow right. even when theres no clogs in the tube, it needs to be shaken once in a while to start draining. What is wrong?
[13:02:34] <Swapper> archivist: exactly what i want to do, but in small scale
[13:02:37] <SpeedEvil> archivist: Are you never ever going to be cutting something of the same density as oil, and will you always remember if you do
[13:02:37] <archivist> SpeedEvil, it is how machine I have used do it
[13:02:52] <SpeedEvil> miss0r|shop: airlock?
[13:03:15] <miss0r|shop> SpeedEvil: perhaps, but the hose is above water surface in the exit end, and it has a steady fall all the way
[13:03:22] <SpeedEvil> hmm
[13:03:32] <miss0r|shop> I am honnestly puzzled

[13:04:03] <Swapper> its so darn hard to get hold of here thats all
[13:04:09] <miss0r|shop> SpeedEvil: I did that already, runs right through
[13:04:10] <Swapper> and to get that size sheet home
[13:04:28] <miss0r|shop> althou, it was a 15mm ball ;)
[13:04:33] <archivist> Swapper, if you have a local company ask then to crop it
[13:04:37] <archivist> them
[13:05:01] <Swapper> i do have one contact that might do tha t
[13:05:03] <Swapper> ill ask
[13:05:10] <SpeedEvil> I guess the right way to do this would be baskets of expanded metal you can lift out that come out with the chips under the settling tank.
[13:05:14] <Swapper> then they can make the bigger sections in a shear
[13:05:20] <Swapper> take 2 min

[17:21:39] <Loetmichel2> it shouldnt be

[17:58:13] <LeelooMinai> Hmm, I saw there's some HAL module for GS2 - how does it relate to Mesa/hostmot2 driver? Can I wire them together or I need to do something else?
[18:00:15] <pcw_home> That is independent of Hostmot2 (a user space comp that talks to a PC serial port or USB-serial adapter)
[18:02:48] <LeelooMinai> So is there any point of using 7i76 for that modbus communication?

[19:52:43] <LeelooMinai> pcw_home: I have one more question about 7i76. In docs I found this: "One RS-422 interface is provided for I/O expansion via a serial I/O daughtercard". Since that VFD has RS-485 input for modbus, couldn't those two be connected?
[19:53:47] <XXCoder> hey lee hows your cnc
[19:54:03] <XXCoder> I recal you had designed platform last time we chatted
[19:54:51] <LeelooMinai> Just ordering the last part - VFD, but I need to have some plan of controling it, so I need to clear out how all of this will work in linuxcnc
[19:55:01] <zeeshan> you cant use that port
[19:55:22] <Jymmm> Here we go...
https://www.youtube.com/watch?v=GXbsK18NaRU
[19:55:23] <XXCoder> I'm still at frame needed stage
[19:55:24] <LeelooMinai> Why?
[19:56:01] <zeeshan> rs422 != rs485
[19:56:03] <zeeshan> different protocol
[19:56:11] <zeeshan> also he told me you can't
[19:56:19] <zeeshan> its meant to do exactly what your quote says
[19:56:23] <LeelooMinai> RS-485 is a superset of RS-422, no? They are both differential.
[19:56:25] <zeeshan> talk to daughterboards only
[19:56:55] <LeelooMinai> A, hm, ok, maybe it's designed for expansions only then
[19:57:01] <zeeshan> exactly
[19:57:09] <zeeshan> and rs422 has a different pinout
[19:57:12] <zeeshan> even though it's differential
[19:57:18] <zeeshan> rs485 only has 3 pins
[19:57:21] <zeeshan> d+ d- gnd
[19:57:50] <zeeshan> i thought you bought a rs232 to rs485 converter?
[19:57:53] <_methods> now that's a trailer
[19:58:26] <Jymmm> _methods: lol
[19:58:46] <LeelooMinai> zeeshan: Well, I read that you can mix them on the NI site: Since RS-422 is a subset of RS-485, all RS-422 devices may be controlled by RS-485.
[19:59:13] <zeeshan> well the reason rs485 is used for vfd
[19:59:25] <zeeshan> is its meant to be used in a multiple transmiter/reciever industrial setting
[19:59:34] <zeeshan> rs422 can only connect one t/r to another t/r
[19:59:58] <LeelooMinai> Right, but I think it can be switched to rs-232 on GS2, so maybe I should just go with that.
[20:00:56] <LeelooMinai> Same socket, different options:
http://i.imgur.com/8e7jTSS.png
[20:01:38] <zeeshan> not sure why you'd wanna down grade to a single ended signal
[20:01:39] <zeeshan> but upto you
[20:01:52] <zeeshan> a rs232 to rs485 converter is like 5bux
[20:02:54] <LeelooMinai> Well, that converter would not give me much though, right - if the cable is short. Maybe USB to rs485 could be faster so would make more sense?
[20:03:20] <zeeshan> i think i when i was looking at usb to rs485
[20:03:26] <zeeshan> they were expensive relative to rs232 to rs485
[20:03:59] <LeelooMinai> The cable will be probably, hm, max 3 feet - not very long
[20:04:58] <zeeshan> is your vfd to motor cable shielded?

[20:06:10] <LeelooMinai> zeeshan: I don't have the cable yet - looked at what automationdirect has, but they seem to have only unshielded 4 pairs for some reason.
[20:06:29] <zeeshan> yea vfd cable is kinda hard to get
[20:06:32] <zeeshan> not a common thing
[20:06:49] <zeeshan> belden and i forgot the other name igus
[20:06:51] <zeeshan> or something makes it
[20:07:21] <zeeshan> well that cable is emitting 14kHz
[20:07:22] <zeeshan> or so
[20:07:27] <zeeshan> depending on your carrier frequency
[20:07:33] <zeeshan> who knows if that is an issue or not
[20:07:35] <zeeshan> try it out :P
[20:07:46] <zeeshan> you wont need a special adapter, its not like you're losing anything
[20:07:47] <LeelooMinai> I have those cables on steppers - but used it all:/
[20:08:15] <LeelooMinai> Should have bought more when I was buying it

[20:10:53] <zeeshan> to get shape recovery rates and curves
[20:11:10] <XXCoder> interesting
[20:11:13] <zeeshan> if this doesnt work out
[20:11:17] <zeeshan> (which i really hope it does)
[20:11:26] <zeeshan> it'll be off to the TEM (transmission electron scope)
[20:11:33] <zeeshan> from what i've heard
[20:11:37] <zeeshan> it takes snap shots
[20:11:42] <zeeshan> unlike sem which does a raster scan
[20:11:56] <dirty_d> Rab, entering i.e. 1 for a linear dimension constraint will give an error box
[20:12:24] <dirty_d> and it catches stuff like 1in * 2in that results in area or 2in / 1in that results in a unitless ratio

[20:27:25] <furrywolf> heh, I have a case of rs485 to rs232 adapters.... got them when I got some stepper drivers that spoke rs485. a case was cheaper than the four I needed...
[20:27:37] <LeelooMinai> I will write it down as "supernatural planning skills"
[20:29:08] <furrywolf> I've never used either the drives or the adapters... anyone want some stupidly overpriced step drives? they don't seem to take step/dir input, which greatly limits their usefulness... instead they want you to write code in their custom language and download it to run in the drive...

[20:42:50] <LeelooMinai> dug*
[20:43:19] <Rab> I'm not sure you can tell from the computer side. FTDI are supposedly writing a new driver that does more subtle detection than just sending invalid commands, but I don't know what method they will use.
[20:43:54] <furrywolf> CaptHindsight: no, I'm waiting for one of www.wetforher.us/all/16-two-black.html to show up today. finglonger isn't its real name, but it's the first thing that came to mind when I saw it. (I don't even have a TV, yet somehow I've seen that futurama episode)
[20:44:28] <LeelooMinai> Rab: I think if it was fake the FTDI driver would just brick it
[20:44:58] <Rab> LeelooMinai, supposedly the toxic driver has been removed from Windows Update.

[20:47:03] <furrywolf> every new version of firefox gets worse, but you have to keep installing them because while the new ones don't have any fewer security problems, they have different problems which hopefully fewer people are exploting.
[20:48:00] <LeelooMinai> I have Chrome for ages - since the first version I think.
[20:48:49] <LeelooMinai> Not much problems with it - but not many plugins installed, just that adblock thingy.
[20:49:09] <XXCoder> tried chrome for a while
[20:49:11] <XXCoder> hated it
[20:49:30] <LeelooMinai> What's there to hate - it's very clean and unobtrusive.
[20:49:34] * furrywolf prefers to support open source
[20:49:47] <XXCoder> and crashy
[20:49:50] <LeelooMinai> Works fast too.
[20:49:51] <XXCoder> and MUCH less options
[20:50:05] <CaptHindsight> https://www.linkedin.com/pulse/25-people-have-4th-cone-see-colors-p-prof-diana-derval
[20:50:22] <furrywolf> I've used chrome a couple times on windows boxes, and found it even slower and buggier than firefox. which takes talent.
[20:50:37] <LeelooMinai> XXCoder: It's not crashy in my experience. Also, each tab has separate process so even if a tab crashes, not a big deal (I think Chrome was the first browser to have tabs in separate processes.)
[20:51:36] <furrywolf> ... that's a crap design.
[20:51:43] <furrywolf> and would only be done if they think their code is crap.
[20:51:54] <LeelooMinai> furrywolf: I use computer for like 12 hours a day 7 days a week and Chrome is in use all the time - I would not keep using it if it had some major problems:)
[20:52:01] <XXCoder> chrome is only browser that I could put to knees bg opening few tabs
[20:52:11] <XXCoder> IE is best on this but firefox is better
[20:53:14] <LeelooMinai> For some reason I seem to have less problems with OSes, software, etc. that most people - not sure why that is... Sometimes I wonder what people do there that those terrible things happen to them:)
[20:53:30] <furrywolf> you probably simply do less. :P

[20:53:53] <LeelooMinai> Right, only this does not really work in my case - I do much more than average user:)

[20:54:42] <furrywolf> speaking of problems... capt: that appears to be a blank page
[20:54:55] <furrywolf> oh, it's because you have to log in.
[20:55:14] * furrywolf does not have and will never have a linkedin account
[20:55:39] <LeelooMinai> I don't even know what it is - but that's probably good
[20:55:54] <XXCoder> linkedin is work professional "facebook"
[20:56:14] <furrywolf> it's a social networking service that survives by spamming every person you know relentlessly until they never speak to you again.
[20:56:38] <LeelooMinai> Right, so as most of those - not desirable:)
[20:56:46] <XXCoder> I will NEVER use their "find assocations by loggin in your emaila ccount"
[20:56:52] <XXCoder> because fuck that

[21:00:11] <furrywolf> need to figure out what the best tool to trim spray foam is... sawzall? kitchen knife? a sawzall blade held in a pair of visegrips? air body saw?
[21:00:45] <XXCoder> hands? teeth? heh
[21:01:31] <furrywolf> no. only silicone rubber goes down my throat, not likely-toxic sprayfoam. :P
[21:01:43] <XXCoder> lol
[21:01:44] <alex4nder> furrywolf: electric carving knife, or a hotwire
[21:01:54] <LeelooMinai> furrywolf: Probably something like one of those keehole saws or what they are called

[21:02:05] <Rab> I've used box cutter, steak knife, drywall knife.
[21:02:11] <furrywolf> I don't have an electric carving knife. I do have a sawzall. it's just like an electric knife, but better.
[21:02:28] <alex4nder> furrywolf: it is indeed not just like an electric carving knife

[21:33:09] <XXCoder> Rab: I still wonder what the flip happened
[21:33:11] <CaptHindsight> 7I77 field inputs are of the sinking type. That is, external power must be applied to the input to register as activated. This mode was chosen so that accidental grounding of an input will not register as an activated input. It is suggested that inputs like limit switches use normally closed switches with one switch leg connected to field power and the other to the 7I77 input pin, so the normal machine state (not at limits) is to have
[21:33:11] <CaptHindsight> the inputs activated. This way, a open switch wire or wire shorted to ground will cause a detectable machine fault.

[22:42:09] <cnc1> ok
[22:42:10] <Swapper> but that is how i read the specs
[22:42:25] <cnc1> its ok

[22:44:08] <cnc1> ok
[22:44:35] <Swapper> there should be 2 lights on the board
[22:44:58] <cnc1> and the second cable from switsh in TB2 pin1
[22:45:01] <Swapper> one close to the external "port" (db25) and one moreat the rright
[22:45:12] <Swapper> no no
[22:45:18] <Swapper> no switches in TB2
[22:45:21] <Swapper> only field power
[22:45:27] <cnc1> ooo
[22:45:33] <Swapper> so the card gets power for the "io"
[22:45:34] <cnc1> :)
[22:46:08] <Swapper> the switch then connects from +15 (same source as the one powering the card) and to GROUND
[22:46:17] <Swapper> ignore that
[22:46:23] <cnc1> 1 cable in TB7 input
[22:46:38] <Swapper> yes and the other to +15v
[22:46:44] <cnc1> 2 cable TN7 output
[22:46:50] <Swapper> no
[22:46:51] <cnc1> ok
[22:47:05] <cnc1> i read to leat
[22:47:20] <Swapper> +15v > TB pin 1
[22:47:55] <cnc1> not TB7 pin 5
[22:48:03] <Swapper> both
[22:48:23] <Swapper> you need +15 to TB2 Pin 5 also
[22:48:42] <cnc1> ok
[22:48:43] <Swapper> and Ground to TB2 Pin 8
[22:49:22] <Swapper> and +15v ---- | switch | --- TB7 Pin 1
[22:49:30] <Swapper> that should work

[23:55:19] <sliptonic> I have some old (circa 1986) optical limit switches that I can't find specs for. If I drive them with 24V, am I likely to destroy them?
[23:57:05] <furrywolf> depends on if they have built-in electronics, or if they're just led+phototransistor... I've never seen one, so have no idea.
[23:57:10] <dirty_d> i hate when i measure something and it doesnt come out to a round number
[23:57:32] <dirty_d> this gears bolt hole circle is 0.9052" averaged over 6 pairs of holes
[23:58:35] <tjtr33> 23mm?
[23:58:37] <furrywolf> aka 23mm?
[23:58:47] <dirty_d> i dont think so
[23:58:55] -!- akex2 has quit [Quit: Connection closed for inactivity]
[23:59:00] <dirty_d> oh wait yes
[23:59:01] <dirty_d> haha
[23:59:04] <furrywolf> are you sure? that's remarkably close to 23mm...
[23:59:33] <dirty_d> my brain wasnt working right for a minute
[23:59:58] <furrywolf> unless you're using a lot fancier tools than I own, that's 23mm to within less than your measurement error. :)
