[02:19:13] <Deejay> moin
[02:19:26] <alex4nder> morning
[05:15:32] <jthornton> morning
[05:16:31] <XXCoder> night
[05:16:35] <XXCoder> whts up
[05:18:11] <jthornton> just waking up
[05:18:17] <XXCoder> cool
[05:19:08] <XXCoder> just chopping up even more HDPE plastic
[05:19:21] <jthornton> http://gnipsel.com/images/540/540-01.jpg
[05:20:00] <XXCoder> so that is what is up in your place, a plane ;)
[05:20:10] <archivist> I wonder what the average flying to crash time is
[05:20:54] <jthornton> prob a long time if your experienced and if not you just glue it back together lol
[05:21:48] <XXCoder> I wonder if can buiold plane out of world lightest material
[05:21:53] <jthornton> http://gnipsel.com/images/blast-cabinet/Blast%20Cabinet%2030.JPG
[05:23:39] <XXCoder> whats a good small materials shredder?
[05:23:48] <XXCoder> for chopping say HDPE
[05:24:06] <archivist> just make your melting pot larger
[05:24:43] <jthornton> http://gnipsel.com/images/blast-cabinet/Blast%20Cabinet%2027.JPG
[05:24:49] <XXCoder> you melted hdpe and made bricks before?
[05:25:38] <archivist> nope
[05:26:16] <XXCoder> would be funny if enough milk is bought to make tons of hdpe bricks, and build a house or garage with it lol
[05:27:13] <XXCoder> some families go thoygh milk like its only thing keeping em alive
[05:27:37] <archivist> jthornton, is the exit pipe a little small at the bottom?
[05:30:16] <jthornton> nope, it fits the bleed valve perfect
[05:31:02] <jthornton> http://gnipsel.com/images/blast-cabinet/extension-04.jpg
[05:31:32] <archivist> I was thinking of large slabs of rust falling down
[05:31:39] <jthornton> bleed valve is the silver thing under the red hobby blast cabinet attached to the black hose going behind right front leg
[05:32:08] <jthornton> large things won't fit through the holes in the perf plate
[05:36:47] <XXCoder> http://go.eliomotors.com/hs-fs/hubfs/LOWRES_-_IMG_1780.jpg
[05:57:43] <Jymmm> XXCoder: hdpe house?! One little fire...
[05:57:50] <XXCoder> indeed
[05:57:57] <_methods> salvador dali house
[05:58:00] <Jymmm> or very hot day
[05:58:21] <XXCoder> hdpe crs melting in summer lol
[05:58:34] <XXCoder> though it dont melt till its 200f or so
[05:58:41] <XXCoder> it probbly atill weakens
[05:59:14] <Jymmm> it can get 140F in a car with the windows rolled up, 200F isn't that far off, leave the hair druer on long enough
[05:59:25] <Jymmm> dryer*
[05:59:35] <XXCoder> lol indeed
[05:59:47] <Jymmm> hot water heateer vent pipe
[05:59:53] <XXCoder> still not too sure what I want to make with hdpe plastoc
[06:00:09] <_methods> milk cartons?
[06:00:14] <Jymmm> make smome milk jugs!
[06:00:17] <XXCoder> _methods: soylent bottles
[06:01:03] <_methods> it's people
[06:01:09] <XXCoder> nah
[06:01:15] <XXCoder> its contents thats people
[06:01:17] <XXCoder> not bottles
[06:01:18] <Jymmm> whats your fasination with hdpe? You want you things to smell like spoiled nasty ass milk???
[06:01:41] <XXCoder> Jymmm: just wanted to play around with it. see what i can do
[06:01:51] <XXCoder> and hey free plastic to cut on cnc for learning and stuff
[06:02:44] <XXCoder> interesting. https://youtu.be/mmT1IVK72xc
[06:02:55] <Jymmm> to muck around with hdpe, you need a stable heat source, and it'll probably cost you more in energy/fuel than to buy new =)
[06:03:29] <XXCoder> sun focus/collumator for free heat
[06:03:41] <Jymmm> STABLE heat source
[06:03:48] <XXCoder> yeah its likely like that, cheaper to buy blocks than make em
[06:04:05] <XXCoder> Jymmm: salt heated by large array stays hot for long time
[06:04:13] <XXCoder> though I cant build to that scale lol
[06:04:29] <Jymmm> STABLE, not intense, PE/PP is very touchy
[06:04:56] <XXCoder> pe/pp?
[06:05:33] <Jymmm> PE = Polyethylene, PP = Polypropylene
[06:06:36] <XXCoder> wouldnt it also mean alum smelting and casting is more expensive than buying alum blocks
[06:06:57] <XXCoder> or am i missing something
[06:08:08] <Jymmm> alum has a value per weight, PE/PP doens't except for CRV value
[06:10:17] <XXCoder> hm ok
[06:12:22] <XXCoder> honestly its more for fun than anything else
[06:13:30] <XXCoder> man
[06:13:38] <XXCoder> that handles design is really good
[06:55:49] <Jymmm> XXCoder: 2x $500/each drawer pulls.
[06:56:12] <XXCoder> maker sells em?
[06:56:23] <Jymmm> oh pleeeeze
[06:56:29] <SpeedEvil> Jymmm: What do you mean by stable?
[06:56:36] <XXCoder> unchanging heat source
[06:56:41] <SpeedEvil> Jymmm: Oven
[06:57:46] <archivist> cooker hot plate, thermocouple and a controller
[06:58:15] <Tom_itx> molten lava beds
[06:58:22] <archivist> best to have a heat holding mass so it varies less
[06:58:38] <Tom_itx> ^^
[06:59:06] <Jymmm> SpeedEvil: Most dont have a big enough oven, PP/PE goes from gooey mess to crunchy crap in about a 10F window
[06:59:24] <archivist> I have a plate in between element and sand pit http://www.collection.archivist.info/searchv13.php?searchstr=kiln+bluing
[06:59:37] <Jymmm> what archivist said would help big time
[07:00:29] <archivist> made for bluing rather than meting but principle is similar
[07:01:05] <Jymmm> archivist: like gun blueing?
[07:01:13] <archivist> yes
[07:01:15] <Jymmm> k
[07:01:27] <archivist> done with heat not chemical
[07:01:33] <Jymmm> nice
[07:02:55] <archivist> earlier examples http://www.collection.archivist.info/searchv13.php?searchstr=hands
[07:03:03] <Jymmm> My "thermal mass" is 50lbs of #30 mesh sand. Slow to get up to temp, but works out very well.
[07:04:08] <Jymmm> Note: 50lbs of sand fits perfectly in a 5gal bucket btw =)
[07:04:17] <archivist> the tray of sand help to get a very even heat over the item
[07:04:43] <Jymmm> also great for putting out any fires =)
[07:05:50] <XXCoder> https://www.youtube.com/watch?v=ziHqQcRflgM
[07:06:00] <XXCoder> hdpe apparently strunks by quite a bit
[07:08:23] <XXCoder> lol Jymmm you might want this https://www.youtube.com/watch?v=VWlj5rYsFg4
[07:22:27] <XXCoder> http://atomicshrimp.com nice site
[07:22:37] <XXCoder> he did a bunch of recycling stuff
[07:26:31] <Jymmm> XXCoder: I like the final product, but not the process. More my style... https://www.youtube.com/watch?v=bsdNZFMplyM
[07:27:06] <XXCoder> ah vacuum foaming?
[07:27:16] <Jymmm> And PS is cheap!
[07:27:21] <Jymmm> yep =)
[07:28:05] <XXCoder> I do want to play with vacuum foaming too
[07:28:12] <XXCoder> though not interested enough to do it
[07:28:31] <XXCoder> there is REALLY cheap tiny ones, made for dentals but work for anything
[07:28:39] <XXCoder> space is enough for dentures so its not big
[07:29:26] <Jymmm> You would be surprised as once you have a design/mold, then you can cretealot of em real quick - especially the whole staw wars / cosplay stuff
[07:29:47] <XXCoder> I heard storm uniform is qyite expensibve
[07:30:10] <Jymmm> And now you can sell em =)
[07:30:28] <Jymmm> raw, let them do all the shitty work =)
[07:31:35] <XXCoder> $10 for 12"x12"x.354 sheet of hdpe lol
[07:32:00] <XXCoder> no wonder hdpe is damned everywhere, its cheap
[07:32:47] <Jymmm> Shit, go steal a bunch of trash cans, they're HDPE
[07:34:32] <Jymmm> err... "borrow", not steal ;)
[07:35:03] <XXCoder> https://www.amazon.com/Seaboard-Density-Polyethylene-Finish-Length/dp/B00JPH9U50 lol
[07:35:09] <XXCoder> no interesting colors though lol
[07:35:18] <XXCoder> milk jugs caps make for a nice pattern
[07:36:56] <XXCoder> interesting http://atomicshrimp.com/post/2013/12/29/More-Plastic-Moulding-Re-Making-A-Missing-Handle
[07:38:49] <Jymmm> XXCoder: DIY vacuum forming machine - I relly like his heater setup for even heat (might add a tiny fan) https://www.youtube.com/watch?v=maH5Ech0wK8
[07:39:42] <Jymmm> XXCoder: IF you make one, be sure to support the cavity of the vacuum table or it will deform
[07:39:51] <XXCoder> looks like ABS
[07:40:09] <XXCoder> ?
[07:40:29] <XXCoder> nice heater solution!
[07:42:41] <XXCoder> autocaptions is mostly nonsense
[07:43:10] <XXCoder> mold ice here 3 balls so on and on. "lip balm shine tonight shan listing"
[07:43:23] <XXCoder> anyway time to sleep laters
[09:30:28] <gregcnc> Erant which phase converter or VFD?
[10:11:23] <CaptHindsight> has anyone tested and found a known working barebones or used PC from NewEgg or similar for use with Linuxcnc and Mesa (PCIe or Ethernet)?
[10:30:08] <pcw_home> the $40 DC7800s work pretty well
[10:33:49] <pcw_home> The Zotac CI323 also works well with Ethernet (it has 2 Ethernet ports)
[10:33:51] <pcw_home> I suspect almost any PC will work with Ethernet if is has a Realtek or Intel MAC
[10:33:52] <pcw_home> Best Ethernet performance I have seen is with H81/H97 MBs (no problem with 4KHz servo threads)
[10:38:27] <enleth> pcw_home: I might be getting another set of Mesa cards for the ORAC soon and I'm thinking of giving the ethernet-based cards a try, just out of curiosity, instead of getting a 6i25/7i77 set. Are there any articles/write-ups/rants/whatever on the practical differences between the two, other than the obvious difference in the bus being used to communicate with the card?
[10:38:53] <CaptHindsight> pcw_home: can the Zotac run two 7i92 at the same time?
[10:39:23] <cradek> enleth: certainly there are extra setup steps
[10:39:57] <alex4nder> CaptHindsight: I use a shuttle ds57u .. it has two independent gige ports
[10:40:25] <alex4nder> it's a cool little box
[11:22:35] <pcw_home> enleth: I would say the main difference is the Ethernet card are a bit harder to setup initially
[11:22:37] <pcw_home> (you need to setup a port with static IP address, you also need a Preemt-RT kernel and the uspace version of LinuxCNC)
[11:24:09] <pcw_home> Yes the Zotac could run 2 at a time (you can run up to 4 Ethernet cards at a time from a single port if you add a switch)
[11:29:23] <lair82> pcw_home, I just got back from swapping out the ssd's to the updated one with the 4.1.20 rt23 kernel on it, and after about 2 hours of solid performance, with the machine running better than it ever has, I got a realtime fault, https://app.box.com/s/bcy2zrj97lixnc5j04vmq6ivc1kc2xde
[11:30:53] <lair82> This thing is a carbon copy to the machine in the shop that has been running flawlessly since I updated the rt kernel on it. The only difference is the machine here is v4.1.13 not 4.1.20
[11:31:40] <lair82> I looked at the "halcmd show param *tmax" output, and the 7i80 read time was right at 4600000.
[11:31:51] <lair82> Any thoughts?
[11:32:17] <lair82> These are the ones with the H97 boards in them
[11:32:20] <pcw_home> BIOs power management?
[11:33:11] <lair82> I looked through it, and it all looked the same as the one here at the shop. is there any way to print the bios settings, so I can go compare them ?
[11:33:25] <pcw_home> Not that I know of
[11:35:09] <lair82> Ok, I will go write everything down then go back and compare them
[11:35:44] <pcw_home> also check the BIOS version in case its different
[11:36:24] <lair82> Ok, didn't think of that
[11:38:45] <pcw_home> Thats a ~1.5 ms delay spike, I dont think there's much other than power
[11:38:47] <pcw_home> management that can do that
[12:42:11] <andypugh> Bother! My workshop flooded again
[12:42:23] <DaViruz> welcome to britain?
[12:42:24] <DaViruz> :)
[12:42:35] <CaptHindsight> time to move to higher ground?
[12:42:35] <andypugh> 35mm depth of water all over
[12:42:48] <DaViruz> that is a bother
[12:43:55] <CaptHindsight> I hate floods. Mold, mildew, even coating of dirt....
[12:44:34] <andypugh> The forecast says it should stop raining on Wednesday
[12:44:37] <lair82> I received almost 2 1/2" of rain in less than 4 hours last night, no flooding, but boy was it coming down
[12:45:42] <CaptHindsight> a few years ago we had 4-6" inches in our shop from a 1 in a 100 year flood....
[12:46:28] <CaptHindsight> ends up the city ignored the Army flood plane maps from years ago and built a street right across a stream bed
[12:46:49] <lair82> That is fantastic,,,
[12:46:49] <djdelorie> we recently had 4" in our basement from a plugged drain :-P
[12:46:51] <CaptHindsight> the street acted as a dam when it filled
[12:47:28] <lair82> It is so dry around my place, there was no standing water when I woke up this morning
[12:49:31] <andypugh> Luckily it can’t get much deeper in my workshop before it runs out the door, and all the CNC electronics is higher than that.
[12:49:46] <lair82> Thats good
[12:50:01] <lair82> How did it flood in the first place?
[12:50:17] <andypugh> Wasn’t so pleased to see that I had left one of my 3-jaw chucks on the floor, but glad that I (totally randomly) put all the others in the cupboard last night
[12:50:39] <DaViruz> the word cupboard has always intruiged me
[12:50:43] <DaViruz> how did it come to be
[12:51:05] <andypugh> lair82: It seems that the water table is only about 2” below the floor slab. After enough rain the water oozes up through the gap between the slab and the walls.
[12:51:25] <andypugh> DaViruz: It was literally a board that you kept cups on.
[12:51:28] <archivist> time for a sump and pump
[12:51:35] <CaptHindsight> on ships would it be "cupplank"?
[12:51:49] <DaViruz> andypugh: but how did it turn into a small closet
[12:51:56] <andypugh> archivist: I decide to do that every time it floods. Then forget.
[12:52:03] <archivist> heh
[12:52:37] <DaViruz> here we usually dig a trench around the slab a fair bit deeper and put a drainage pipe in if the water table is a too high
[12:52:45] <archivist> I had the doors open letting the air in today, no rain up here :)
[12:53:00] <andypugh> DaViruz: Compare to “Sideboard”
[12:53:20] <archivist> floor board
[12:53:30] <CaptHindsight> andypugh: if the water table is that close to the surface a sump would just run continuously
[12:53:31] <DaViruz> overboard
[12:53:32] * archivist ducks
[12:54:23] <lair82> Aaaahhh, makes sense, a place I used to work at, the building was 400' wide by 250' deep, one spring we received a ton of rain over the course of a week, by the end of the week, water was coming up through the floor, in the CENTER of the building.
[12:54:35] <CaptHindsight> we have ducks in our overflow pond
[12:55:02] <archivist> while sitting on the throne I found an interesting schesinger article in the Imeche from 1938 Machine tool tests and alignment
[12:58:43] <archivist> I think the online price is a bit too high http://pme.sagepub.com/content/138/1/59.abstract
[12:59:18] <_methods> is that brexit thing over yet
[12:59:55] <_methods> you guys are messin up my 401k
[12:59:56] <archivist> polling stations still open till 10pm
[13:00:22] <archivist> votin the EU off out island
[13:00:30] <archivist> our
[13:00:34] <_methods> who's gonna pay for greece
[13:00:45] <archivist> them others
[13:00:48] <_methods> hahah
[13:00:57] <CaptHindsight> Greece will be under private ownership
[13:01:06] <CaptHindsight> like Disney
[13:01:12] <CaptHindsight> only with gyros
[13:01:25] <_methods> never a good idea to let greece or italy get involved in anything besides catering food
[13:02:03] <archivist> italy can just about make a sports car too
[13:02:12] <andypugh> I expect the vote will be to stay in. But the heavy rain is likely to make the turnout low.
[13:02:19] <CaptHindsight> how about Spain?
[13:02:38] <CaptHindsight> what's Spain done for us lately?
[13:03:00] <andypugh> I am kind of in favour od _an_ EU, but less so of the one we have.
[13:03:48] <_methods> well at least this time germany will have a good reason for attacking you guys
[13:03:58] <_methods> leaving them holding the bag lol
[13:04:15] <archivist> they keep losing wars /me not worried :)
[13:04:19] <_methods> hahah
[13:04:51] <andypugh> I am failry sure the single currency has not worked out as well as anticipated.
[13:05:10] <_methods> they'll be the last ones left at the party with those 2 annoying hairy stinky guys........greece and italy
[13:05:37] <CaptHindsight> maybe we can sell them a wall or two
[13:05:44] <andypugh> Britain used to have the largest and best-trained army in the world. All we need to do to get it back is re-invade India :-)
[13:05:45] <_methods> yeah we got a guy
[13:05:51] <_methods> he knows how to build walls
[13:05:52] <Sync> andypugh: if it was actually meaning something I'd actually take it seriously
[13:05:54] <_methods> on their dime
[13:06:35] <_methods> mexico will pay for your walls
[13:06:42] <CaptHindsight> I thought that India was invading the UK
[13:07:02] <CaptHindsight> they took over your menus
[13:07:10] <andypugh> CaptHindsight: Not to anything like the extend that the Leave Camp would have you believe.
[13:07:12] <_methods> hehe
[13:08:24] <andypugh> CaptHindsight: To an extend, but Vindaloo is Portugese and Tikka Masala is Scottish: https://en.wikipedia.org/wiki/Chicken_tikka_masala
[13:10:31] <CaptHindsight> well first they invaded Glasgow, then came up with a marketing name ...
[13:14:19] <CaptHindsight> http://www.historic-uk.com/CultureUK/Food-in-Britain-in-the-1950s-1960s/
[13:16:24] <Tom_itx> CaptHindsight get much for storms last night?
[13:16:26] <archivist> heh that article is right, my mum could produce cold and burnt baked beans in the same saucepan
[13:16:37] <CaptHindsight> haha
[13:17:55] <andypugh> My mum is a keen cook, and pretty good at it. She managed to never cook the same meal twice during her first year of marriage (a challenge I thnk she had set herself long beofrehand)
[13:19:29] <CaptHindsight> Tom_itx: spotty heavy rain and wind, tornado's to the south
[13:20:04] <CaptHindsight> nice today 68F and sun
[13:22:06] <SpeedEvil> https://youtu.be/tf7IEVTDjng more Boston dynamics
[13:22:28] <SpeedEvil> I guess it is still hydraulic
[13:22:35] <CaptHindsight> at our house it was how many calories could you consume in the shortest amount of time, yet I was always as skinny as a bean pole
[13:24:32] <CaptHindsight> they have managed to make robots as annoying as dogs, except for the ones that actually help around the house
[13:33:50] <djdelorie> the robots or the dogs?
[14:05:57] <CaptHindsight> who makes high temp >200C and sealed (gas tight) versions of these? http://www.linearmotionbearing.com/steel-cage-linear-bearings-1.html
[14:06:32] <CaptHindsight> http://www.linearmotionbearing.com/flange-type-linear-bearings-1.html
[14:06:42] <andypugh> Try Mahle
[14:07:16] <andypugh> No, wait, completely the wrong company.
[14:08:54] <andypugh> I meant Mahr, but having looked, I don’t think that they do.
[14:09:43] <CaptHindsight> going to need to support 3/8"-1/2" rods over 8-10" of travel in an oven with various gases
[14:11:25] <CaptHindsight> https://static.grainger.com/rp/s/is/image/Grainger/2LFV2_AS01?$zmmain$ might have to use some seals like these
[14:12:08] <Deejay> seems broken ;)
[14:12:15] <CaptHindsight> hehe
[14:19:07] <SpeedEvil> CaptHindsight: the alternative way is to not do that, and to seal in the cold outside
[14:19:40] <CaptHindsight> if the bearings can hold up to the temp
[14:21:25] <CaptHindsight> http://daemar.com/shaft_seals_14.html
[14:27:44] <CaptHindsight> http://daemar.com/shaft_seals_14.html
[14:31:05] <CaptHindsight> http://www.allsealsinc.com/teflon-products.html
[14:56:08] <Tom_itx> http://www.lily-bearing.com/ceramic-bearings/applications-ceramic-bearings/high-temperature/?gclid=CJf33_7wvs0CFQctaQodZtsBRA
[14:56:13] <Tom_itx> CaptHindsight, ceramic
[14:58:22] <Tom_itx> http://www.specialtycomponents.com/?gclid=CJ70m8jxvs0CFQsDaQods6sJPw
[16:37:15] <Deejay> gn8
[16:41:02] <CaptHindsight> Tom_itx: those are fine for temperature but they still need a seal to keep the hot gases from escaping, and the movement is axially
[16:44:37] <gregcnc> my 70$ fluke 362 arrived. Seems legit. the box is marked "fluke calibration certificate india" was made in china
[17:06:28] <Vq> The village India located in China?
[17:11:17] <Frank_11> later tell us how it turns out, im still figuring out which to buy
[17:16:10] <Tom_itx> CaptHindsight yeah i was reading something about 'face' seals
[17:17:27] <Tom_itx> maybe that other link has something
[17:19:02] <Tom_itx> https://en.wikipedia.org/wiki/Dry_gas_seal
[17:19:48] <Tom_itx> https://www.johncrane.com/products/mechanical-seals/dry-gas
[17:21:55] <Sync> yeah they are pretty cool
[17:32:42] <jdh> I got a fluke 287 today. pretty nice, but wasn't my money.
[17:45:35] <andypugh> gregcnc: AvE took one apart. But I couldn’t watch it. He annoys me by damaging parts in obvious places when he could choose hidden places.
[17:48:22] <gregcnc> I guess this one was India market, warranty is for India. 30usd less than ebay so pretty cheap. not sure if AvE does those things intentionally or not, but I take it for the comedy that it is.
[17:49:09] <gregcnc> i just hope india amps and volts are the same as ours
[18:11:50] <_methods> https://www.youtube.com/watch?v=F6obic1uh7o
[18:11:51] <_methods> yep
[18:11:53] <_methods> they're the same
[18:11:55] <_methods> lol
[18:27:00] <andypugh> I think I stopped that just in time
[18:28:25] <CaptHindsight> Tom_itx: yeah I found some pretty elaborate seals for high temp and pressure where many HP are involved
[18:29:53] <Valen> https://github.com/nvbn/thefuck command line fixer watch the GIF at least lol
[18:31:20] <Valen> Ave bugs me a bit with many things he does, if he doesn't get something it's stupid
[18:36:57] <SpeedEvil> yeah
[19:13:46] <Frank_11> hellop
[19:18:01] <andypugh> Hellop to you too.
[21:09:25] <Polymorphism> around $50 shipped for a new ballscrew//nut
[21:15:31] <Polymorphism> perhaps I should have just left it on there as is
[21:15:49] <Polymorphism> I was actually considering just calling the project a total loss, but I realized I should probably try to press forward with this much invested
[21:16:38] <alex4nder> what did you do, ray?
[21:18:10] <malcom2073> How'd you break your ballscrew?
[21:21:18] <Polymorphism> I unscrewed it partially off like a press to remove partially stuck end bearing, some balls dropped out, couldnt get them back in. Took apart to try, failed multiple methods. Gave up. now 0 balls inside
[21:21:36] <malcom2073> Ah wow
[21:22:08] <gregcnc> just takes some practice to reassemble
[21:22:29] <Polymorphism> I tried to feed them in but didnt have much luck. perhaps I'll try a third time
[21:22:38] <Polymorphism> I also tried packing the nut with heavy grease and putting all the balls into their tracks
[21:22:48] <Polymorphism> it almost screwed on until the last couple threads then jammed
[21:22:55] <Polymorphism> took apart again, failed like this 3 times
[21:23:10] <malcom2073> You want to put it together with no grease, and grease it after
[21:23:14] <Polymorphism> next time I'll go back to the feeding in one row at a time method
[21:23:51] <gregcnc> most importantly once you pack all the ball back in you use something to keep them in place as you reinstall the screw
[21:24:11] <gregcnc> rod = to minor diamater of the screw
[21:24:23] <gregcnc> i use grease to hold the ball in place?
[21:24:32] <Polymorphism> I tried to use grease to hold them yes
[21:24:36] <Polymorphism> but maybe also a rod.....
[21:24:42] <Polymorphism> push inside once they are in place
[21:24:48] <Polymorphism> and as I screw it on it will push the rod out
[21:25:04] <Polymorphism> the linear bearings came with foam packed in them and you slide them on pushing the foam out to keep the bearings ion place
[21:25:09] <Polymorphism> so similar idea I gues... might work
[21:26:23] <gregcnc> the rod is the correct method. ballnuts ship with a tube to retain the balls
[21:26:47] <Polymorphism> hmm.... ok
[21:26:51] <Polymorphism> this might work!
[21:26:56] <Polymorphism> so just put in the heavy grease
[21:27:08] <Polymorphism> I used grease for my trucks ujoints etc
[21:27:11] <Polymorphism> not sure if thats really ok
[21:27:14] <Polymorphism> but it held the balls greatr
[21:27:20] <Polymorphism> but this time, I will put a rod in after
[21:27:24] <Polymorphism> to keep them in palce as I try to screw it back on
[21:27:35] <Polymorphism> I'll get the rod from home depot in the perfect size
[21:27:39] <Polymorphism> wood dowel perhaps
[21:28:32] <gregcnc> this is the usual way, without the balls fall out of the tracks regardless of grease
[21:32:05] <Polymorphism> that was what kept happening
[21:32:15] <Polymorphism> they would fall out of place and jam up as I tried to put it back on
[21:47:15] <andypugh> Is this a ball-nut with an external return tube or with the short plastic returns?
[21:48:03] <andypugh> The former type can be re-filled by taking the tube off, the latter type by carefully filing one circuit at a time.
[21:52:53] <Polymorphism> andit has 3 plastic pieces
[21:52:56] <Polymorphism> ball returns
[21:53:01] <Polymorphism> they are visible from the outside

[21:53:53] <Polymorphism> like that
[21:53:58] <Polymorphism> http://g03.a.alicdn.com/kf/HTB1G2r7IXXXXXX.XXXXq6xXFXXXx/TBI-SFU1605-C7-ballnut-for-1605-ball-screw-high-stability-CNC-kit.jpg
[21:53:59] <Polymorphism> exactly that
[21:54:04] <Polymorphism> but black wipers
[21:54:12] <Polymorphism> retained by octagonal clips
[21:54:16] <Polymorphism> one on each side
[21:54:24] <Polymorphism> everything else looks the same
[21:56:08] <Polymorphism> I see the tube in there
[21:56:11] <Polymorphism> that it probably ships with
[21:57:16] <Polymorphism> do they need to be distributed evenly in the tracks andypugh, gregcnc
[21:57:28] <Polymorphism> or do I just pack them all into the tracks anywhere they can fit, and then push a tube through
[22:22:56] <jdh> mine had 17 per track
[22:24:33] <Polymorphism> I didnt ocunt the balls
[22:24:36] <Polymorphism> there were a lot in there
[22:24:37] <Polymorphism> perhaps 50
[22:24:43] <Polymorphism> maybe 61
[22:25:21] <jdh> or 51
[22:25:49] <jdh> afaik, you have to reload them with the screw in the nut
[22:26:13] <Polymorphism> I think I can pack them with it apart
[22:26:18] <Polymorphism> and put the rod in like gregcnc is saying
[22:27:08] <jdh> I don't think you can
[22:27:10] <Polymorphism> http://g03.a.alicdn.com/kf/HTB1G2r7IXXXXXX.XXXXq6xXFXXXx/TBI-SFU1605-C7-ballnut-for-1605-ball-screw-high-stability-CNC-kit.jpg
[22:27:12] <Polymorphism> this is why I think that
[22:27:21] <Polymorphism> it appears to be the packaged state of a brand new one
[22:27:28] <Polymorphism> which I'm about to be charged 50 bucks for
[22:27:32] <jdh> doesn't mean it was loaded taht way
[22:27:33] <Polymorphism> perhaps I should just order from china
[22:27:35] <Polymorphism> direct
[22:27:42] <Polymorphism> I noticed some small slivers of metal in the ballnut
[22:27:46] <Polymorphism> after disassembly
[22:27:49] <Polymorphism> I documented them
[22:27:54] <jdh> to what end
[22:28:07] <Polymorphism> part of the build log
[22:28:30] <jdh> I tried to keep mine together.
[22:28:34] <Polymorphism> ostensibly it's a premium ballnut/screw as I paid extra for it
[22:28:44] <Polymorphism> so I'm suprised the metal was in there
[22:28:54] <jdh> but after I failed at that, I was happier with the smoothness after I cleaned/repacked
[22:33:19] <jdh> https://www.youtube.com/watch?v=GXdt5M8ZeoE
[22:33:51] <Polymorphism> I tried that vid twice, will try again
[23:12:17] <Polymorphism> http://2ndrun.tv/news_directory/national/cnn/
[23:24:49] <CaptHindsight> why do the Chinese use non-spherical ball bearings in their ballscrews?
[23:25:42] <CaptHindsight> a) Because crunchy sounds aren't just for breakfast cereals anymore.
[23:26:28] <CaptHindsight> B) You have already paid them and it will you too much for return shipping
[23:28:57] <CaptHindsight> BRITAIN BAILS!
[23:35:57] <yasnak> amazing how much way oil these new machines use
[23:36:31] <yasnak> cannot be normal...freaking 5 gallons in less then a week. mind you 24/7 but that seems excessive.
[23:36:45] <Polymorphism> lol
[23:36:52] <Polymorphism> thirsty
[23:36:59] <CaptHindsight> is there a puddle on the floor?
[23:37:32] <yasnak> eh, not way oil I don't think
[23:38:10] <CaptHindsight> how big is this machine?
[23:38:28] <yasnak> the CAV barloader has this air blade that sprays the VG 16 oil off bars while feeding. put a restrictor on that and not so much more oil. then if the high pressure is aimed in the wrong spots the machine will slowly leak.
[23:38:33] <CaptHindsight> 5 gallons is quite a large volume of oil
[23:38:43] <yasnak> its a citizen. our smallest swiss actually
[23:39:14] <yasnak> k16e type 3
[23:39:16] <CaptHindsight> ah so it ends up on the parts
[23:40:43] <yasnak> it may be turning into mist. but honestly the tri-mist on it is doing quite well
[23:41:42] <CaptHindsight> not something you want to be inhaling
[23:46:22] <yasnak> i've essentially huffed hex chrome for 10 years...my time is already limited heh
[23:46:55] <yasnak> I kid, but seriously, being soaked in cutting oil and such all day can't be good for you no matter what lol
