[00:02:40] <renesis> rab: nice
[00:07:01] <andypugh> The stepdir PRU code isn’t very long. It might not be very hard to find where the pin-state is written and do it differently.
[00:09:41] <andypugh> Right, I have things to do tomorrow, night all
[00:09:48] -!- andypugh has quit [Quit: andypugh]
[00:24:09] <unfy> so i start to look into building an electronics workbench thing... and i hit $160 easily ._.
[00:24:32] <unfy> and that's just metal frame and a decent piece of plywood for the benchtop ._.
[00:27:24] <renesis> uline benches are that price
[00:30:13] <unfy> so far, not seeing anything from uline that i like
[00:33:20] <unfy> granted, $160 gets me 2 steel frame sides, 6 cross beams, and a sheet of wood that will cover both the table and "ceiling" of the thing. should give me 48"x30" working space at 6 feet tall
[00:34:01] <unfy> would then need to add backing, lighting, power distribution, antistatic mat, etc
[00:36:07] <unfy> would also be a bit of shelving to figure out

[00:39:36] <_methods> workbenches are expensive
[00:39:36] <_methods> i used and old server rack PDU for my power lol
[00:40:16] -!- AR__ [AR__!~AR@24.238.81.234.res-cmts.sth2.ptd.net] has joined #linuxcnc
[00:40:53] <renesis> i think they have most of that stuff
[00:41:51] <renesis> i get the 48" tripp lite strips and screw them to the back edge, i dont use the outlet breakouts in the legs
[00:42:25] <renesis> but yeah prob end up being closer to $400
[00:42:37] <unfy> i'll have to get the thing built then try to figure out how i wanna do power and shelving and small parts bins (if at all) et
[00:43:02] <renesis> small parts pins is the other reason i like the power strips
[00:43:25] <renesis> they keep the stacking akro bins from pushing off the back of the bench
[00:44:23] <unfy> i've got ~20 of the akro bins, and a hanger contraption cabinety thingie for them - but i just can't bring myself to find a use for it.
[00:45:43] <unfy> maybe i could move some of my larger hardware stuff to it (as in 1/4" and bigger nuts and bolts etc)
[00:45:49] <renesis> throw solder wick and spools in one, put gel flux and sticks by itself in another by themselves (gets messy)
[00:46:20] <renesis> then usually one for picks, spudgers, xacto knifes, little files
[00:46:38] <unfy> i do most of that in small parts bins or little storage boxes
[00:46:42] <renesis> another for pens, sharpies, postits, inspection dots and shit
[00:47:09] <renesis> yeah i just mean on a bench
[00:47:37] <renesis> normal akro bins kind of too big for small parts and too small for cables
[00:47:40] <unfy> i guess i'll get the 'foundation' built and then go about by "feel" with what i might wanna do for organization as time goes on heh
[00:48:01] <renesis> these...
[00:48:07] <_methods> yeah a workbench is a work in progress all the time
[00:48:24] <renesis> http://www.amazon.com/Sterilite-16428012-6-Quart-Storage-See-Through/dp/B002BDTETW
[00:48:35] <renesis> and yeah, what _methods said
[00:48:45] <_methods> i use those for project bins
[00:48:47] <unfy> since i'm using a small 12" x 16" wooden free standing/folding TV dinner tray thing right now :P
[00:48:49] <renesis> clear bins are awesome
[00:48:52] <_methods> in progress projects
[00:49:03] -!- asdfasd has quit [Ping timeout: 246 seconds]
[00:49:05] <unfy> yup, i've got 30 or so of the 6qt storage bins :D
[00:49:26] <_methods> i buy the little ones at the grocery store for small projects
[00:49:43] <unfy> and i've got about a dozen small parts bins cabinets
[00:49:45] <_methods> the ones for like food leftovers
[00:50:12] <unfy> i've been debating better quality tote bin things instead of the 'cheapest 6qt shoe box sized' thing i can find... i sunno
[00:50:29] <_methods> it depends on the project
[00:50:42] <_methods> junk projects get junk boxes lol
[00:51:26] <unfy> i've been storing anything and everything in them
[00:51:43] <unfy> (moved about a year ago and have been wanting some sanity to the sheer amount of crap i have)
[00:51:58] <_methods> yeah i go in phases
[00:52:06] <_methods> i'll get it organized for awhile
[00:52:10] <_methods> then it gets out of hand
[00:52:20] <_methods> back to organized
[00:52:28] <_methods> wife yells at me
[00:52:39] <_methods> back to organized
[00:53:27] <_methods> i always have like 10 projects in varying states of unfinishedness
[00:53:31] <unfy> indeed
[00:53:45] <_methods> waiting on parts
[00:53:59] <unfy> i've been doing well at getting things contained. a good work bench will help steam roll that along
[00:54:24] <unfy> either this week or next i'll build me the work bench
[00:54:52] <_methods> i picked up a couple unfinished cabinets at home depot
[00:55:01] <_methods> and then put some melamine on top of it
[00:55:29] <_methods> so i got cabinets with drawers and a bench all in one shot
[00:55:55] <Jymmm> concrete counter tops =)
[00:56:04] <_methods> i would have liked to get my hands on a couple vidmars instead
[00:56:11] <_methods> but those things are hard to get at auctions
[00:56:18] <_methods> people always bid them up to like $700
[00:56:19] <unfy> a coworker has done the beefy filing cabinet + solid core door thing.
[00:59:04] * unfy watches one of the eevblog bench things
[00:59:47] <_methods> those mats.......so over priced
[01:00:00] <_methods> just hook up to ground lol
[01:00:23] <unfy> here at work, we didn't give a shit about ground. cheap folding table + cardboard topper
[01:00:25] <_methods> i dont' fry enough stuff to make it worth while
[01:00:50] <unfy> or - currently - a nice old office metal desk + quilter's cutting board top
[01:01:42] <_methods> yeah those esd mats are nice but i'd rather put my money into a nice boom microscope or oscope
[01:02:07] <unfy> microscope: planned. scope: haz already :P
[01:02:45] <unfy> i have a cheap usb thing for inspection - but nothing for soldering atm. not even a lens-light table clamp thing
[01:02:58] <_methods> the microscope is the thing that i end up wishing i had more times than anything

[02:01:20] <furrywolf> tint applied. not that difficult. made a few mistakes, mostly because it was dark, but it's good enough. and cost $5 instead of $50.
[02:02:17] <furrywolf> don't apply window tint if it's going to get dark in the middle of the project. also, don't stop to pull your neighbor's lawn care people out of the ditch while you're in the bubble-removing stage.
[02:02:55] <XXCoder> cool'
[02:03:26] <furrywolf> the biggest mistake, related to lack of light, was missing a few specs of dirt while cleaning.
[02:03:33] <XXCoder> doh
[02:05:00] <furrywolf> I spent longer cleaning than I did applying!
[02:05:16] <furrywolf> the used window I got was _filthy_. covered in green mold slime.
[02:05:30] <XXCoder> wow but cheap?
[02:08:44] <furrywolf> $50. nothing is ever cheap from the local wrecker.

[03:04:11] <PetefromTn_> Hello LinuxCNC!
[03:04:49] <Tom_itx> did you figure out ngcgui?
[03:04:57] <PetefromTn_> why hell no LOL
[03:05:07] <PetefromTn_> but I did look at it a bit.
[03:05:16] <PetefromTn_> excited to get to use it soon on this lathe.
[03:05:29] <Tom_itx> just move some files around and add a few entries to the ini
[03:05:55] <Tom_itx> seems that slow boat from china is in town now
[03:06:04] <Tom_itx> maybe i'll get some junk tomorrow
[03:06:05] <PetefromTn_> I managed to meet with my customer and had a GREAT meeting today...
[03:06:16] <_methods> good deal man
[03:06:18] <PetefromTn_> I hope so for your sake
[03:06:25] <Tom_itx> just an MPG is all
[03:06:26] <_methods> you still working at that other shop?
[03:06:38] <PetefromTn_> yeah we are working on a product idea
[03:06:44] <PetefromTn_> yeah sorta part time
[03:07:00] <PetefromTn_> I did not take that bridgeport knee mill job tho.
[03:07:08] <PetefromTn_> at least not so far HEHE
[03:07:36] <PetefromTn_> We are working on a cool product for the mazda RX7 guys that seems pretty awesome if we can pull it off.
[03:07:48] <PetefromTn_> The guys are very excited about it
[03:07:52] <PetefromTn_> and so am I
[03:08:07] <PetefromTn_> and they paid me again in full for this short run of parts I am making now today
[03:08:13] <PetefromTn_> which is always nice
[03:08:17] <PetefromTn_> ;)
[03:09:01] <PetefromTn_> so after work I picked up my wife and we headed into Knoxvegas for dinner out and a visit to Horrible freight
[03:09:24] <PetefromTn_> http://i.imgur.com/VkrQt5A.jpg grabbed one of these
[03:10:28] <Tom_itx> vaccuum pump?
[03:10:33] <PetefromTn_> yup
[03:10:53] <PetefromTn_> also they were having some kinda huge sale there today
[03:10:54] <Tom_itx> from there i hope it lasts more than a day
[03:10:56] <PetefromTn_> place was packed LOL
[03:11:13] <Tom_itx> the drill i got from them didn't
[03:11:15] <PetefromTn_> honestly it looks pretty nice from first impressions
[03:11:20] <Tom_itx> so did the drill

[03:11:30] <Tom_itx> angle head didn't make it thru the first hole
[03:11:44] <PetefromTn_> well we shall see I guess
[03:12:07] <PetefromTn_> I actually bought a small dual tank compressor for site woodworking installations from them years ago and it still works great.
[03:12:19] <PetefromTn_> it is also pretty quiet
[03:13:04] <PetefromTn_> http://images.harborfreight.com/cpi/photos/95400-95499/95498.gif looks kinda like this one
[03:13:17] <Tom_itx> we didn't use a reserve tank on ours
[03:13:30] <Tom_itx> i don't see too much benefit with one
[03:13:51] <PetefromTn_> while I was there I grabbed some nice looking ball end allen wrench sets imperial and metric as my old set is missing a few
[03:13:59] <PetefromTn_> on your vacuum pump?
[03:14:04] <Tom_itx> yeah
[03:14:30] <PetefromTn_> I have one and was considering using it
[03:14:45] <Tom_itx> just more to evacuate
[03:14:54] <Tom_itx> the volume on the plate is minimal
[03:15:13] <PetefromTn_> the pump was just $99 so if it does fail it is not the end of the world
[03:15:18] <PetefromTn_> sure
[03:15:36] <PetefromTn_> I have some nice push lock angled fittings I want to use on the fixture
[03:15:57] <PetefromTn_> and I need to get a ball valve and some tubing altho I might have some tubing that will work already
[03:19:30] <PetefromTn_> really excited to start using vacuum hold down techniques on the CNC mill.
[03:19:44] <PetefromTn_> it would have been really nice for the edge lit LED sign too
[03:20:25] <zeeshan> fuck
[03:20:33] <zeeshan> the hydraulic cylinder exploded!
[03:20:35] <unfy> son of a
[03:20:38] <unfy> zee: doh!
[03:20:42] <zeeshan> it didnt
[03:20:46] <zeeshan> but it would be exciting if it did
[03:20:47] <PetefromTn_> define exploded
[03:20:50] <zeeshan> i cant figure how to get it out
[03:21:01] <zeeshan> i've pulled out the fingers that hold the retention knob
[03:21:06] <zeeshan> i dont see how else its being held in there
[03:21:23] <unfy> bought metal stuff and some 1/2" plywood for electronics workbench. realized i forgot some particle board / osb.... and the store is closed now. damnit.
[03:21:49] <zeeshan> delicious metal
[03:21:52] <zeeshan> i love metal!
[03:22:32] <Tom_itx> is it threaded?
[03:22:50] <zeeshan> yea thats how i got the fingers off
[03:23:00] <zeeshan> ill take a bit in a bit, eating :)
[03:23:09] <zeeshan> late dinner :/

[03:29:02] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[03:29:22] <PetefromTn_> this little vac pump is pretty cool
[03:30:00] <PetefromTn_> I need to ante up and get some large plate stock so I can make a nice big pneumatic hold down fixture on the VMC
[03:30:09] <bobo_> come with oil ?
[03:30:22] <bobo_> vav oil
[03:30:23] <PetefromTn_> yeah it did actually
[03:30:39] <PetefromTn_> and it appears to have some inside
[03:30:49] <PetefromTn_> you can see it in the view window
[03:31:15] <bobo_> my fingers are now uncrossed
[03:31:24] <PetefromTn_> ?
[03:31:30] -!- gennro has quit [Quit: Leaving]
[03:31:41] <bobo_> no oil start
[03:33:01] <bobo_> was hopeing for oil
[03:33:41] <PetefromTn_> it has oil and a bottle of it as well
[03:34:31] <bobo_> keep on keeping on -------was just worried
[03:35:02] <PetefromTn_> well I have to get some stuff so I can hook it up tomorrrow
[03:35:17] <PetefromTn_> and I now need to order a bunch of material for the parts run.
[03:35:49] <bobo_> order from where ?
[03:36:15] <PetefromTn_> from my local supplier

[03:36:49] <PetefromTn_> whats nice is the prototype I made for them worked perfect the first time so I just need to make a bunch more now heh
[03:38:05] <bobo_> walk --drive -local ? or phone and wate ?
[03:38:44] <PetefromTn_> phone and wait then drive about 15 minutes to pickup
[03:38:55] <PetefromTn_> usually next day or so
[03:42:10] <bobo_> great except the walking past the drop bin always gets me in fits. like gee I could/might use that piece or that piece looks usable
[03:42:49] <PetefromTn_> oh yeah man and they have a huge rack of small stuff as well as smaller drop pieces on the floor next to it.
[03:43:05] <PetefromTn_> I often grab a couple small pieces and they usually sell it to me by the pound at a good price
[03:43:10] <bobo_> Oh ! stop
[03:44:10] <bobo_> envious
[03:45:09] <PetefromTn_> well it is no big deal really. you should drop by your local machine shops and bring donuts you would be amazed at the scrap they will let you have for free or cheap....unless they are assholes

[03:47:13] <zeeshan> dunno whats holding it in now :/
[03:47:32] <PetefromTn_> does the whole damn thing unscrew?
[03:47:41] <zeeshan> hmm
[03:47:45] <PetefromTn_> that is a cool looking pullstud setup tho
[03:47:58] <zeeshan> PetefromTn_: you prolly have the same thing
[03:48:04] <zeeshan> ott jakobs pretty much makes all the drawbars
[03:48:09] <PetefromTn_> no my pullstud is quite a bit different
[03:48:17] <PetefromTn_> it is a lot like the HAAS style
[03:48:20] <zeeshan> o

[03:49:04] <zeeshan> special tool was made!
[03:49:06] <zeeshan> it turned out pretty hnice
[03:49:10] <Tom_itx> PetefromTn_, you should make a trip over here to the surplus and grab some of the plate
[03:49:22] <PetefromTn_> http://thumbs4.ebaystatic.com/d/l225/m/mRMlkam4A0EqK913q138wOg.jpg mine look like this sorta
[03:49:55] <PetefromTn_> hey thats pretty nice man
[03:50:05] <PetefromTn_> did you turn that on your CNC lathe?
[03:50:12] <zeeshan> yea
[03:50:19] <PetefromTn_> Tom_itx Man if I could get good prices I might consider it LOL
[03:50:24] <PetefromTn_> looks good zeeshan
[03:50:28] <zeeshan> check this out dude i was getting such a shitty finish using vnmg 331 inserts
[03:50:34] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/local_stock/stock_index.php
[03:50:44] <zeeshan> i was spinning at 150 sfm , feedrate 3.8ipm
[03:50:51] <zeeshan> read the specs on the insert package
[03:50:53] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/local_stock/7.jpg
[03:50:56] <Tom_itx> PetefromTn_^^
[03:50:56] <zeeshan> 400 minimum - 800 sfm
[03:51:05] <zeeshan> feedrate worked out to 10 ipm
[03:51:11] <zeeshan> did that, and holy cow it made a much better finish
[03:51:44] <PetefromTn_> damn that is some nice thick material I am sure they want a fortune for it.
[03:51:53] <Tom_itx> by the pound
[03:52:03] <Tom_itx> i don't know what the going rate is right now

I pointed out one pound wouldn't make any difference. "but it does! if you're off by one pound, then you're off by another pound here and another pound there, and it adds up!" etc.
[04:15:02] <furrywolf> if he does that again, I'm going to ask how much his last bowel movement weighed, and if he remembered to calculate the change in cg...
[04:15:04] <bobo_> zeeshan I think it is threaded into spindle . also loctite . can you borrow a hair dryer

[04:15:54] <zeeshan> untorque = loosen

[05:26:56] <zeeshan> PetefromTn_andro: that lathe costs like 10k!
[05:27:08] <PetefromTn_andro> More than that man
[05:27:17] <zeeshan> i dont think its worth it
[05:27:24] <zeeshan> at least from a retrofit perspective
[05:27:30] <zeeshan> when you can have much better machines for 10k
[05:28:08] <PetefromTn_andro> I agree but I do think they did a nice job designing the machine tho
[05:28:11] <bobo_> give him a brake -fron central ohio ----------think he has a busines degree raised in a very small town
[05:28:57] <PetefromTn_andro> For what it is it looks like a nice little machine but I would not buy one..
[05:29:13] <zeeshan> that machine is for noobs

[05:29:23] <zeeshan> not pros like us

[05:29:33] <zeeshan> :P
[05:29:48] <PetefromTn_andro> Meh not really it is just a nice little slant bed collet lathe
[05:30:07] <zeeshan> needs dual spindles
[05:30:08] <zeeshan> !
[05:30:29] <PetefromTn_andro> Not really all that different from a lot of other commercial Collette lathes out there
[05:30:55] <PetefromTn_andro> Just small and designed to run off single phase
[05:32:07] <PetefromTn_andro> The big problem is that fully equipped with the tool turret and pneumatic Collette closer it is gonna be really close to20k apparently
[05:38:40] <PetefromTn_andro> At least it already runs on linuxcnc hehe

[06:01:06] <bobo_> try www.dialog5.com ----wessley's project -----bottom of page ---has chart

[06:19:31] <zeeshan> my suggestion is a bit crude
[06:19:37] <zeeshan> but i would truncuate that program.
[06:19:50] <anarchos2_> well i did, yeah, but have been busy with work for 5 or 6 months so it's been a while
[06:19:53] <zeeshan> like run 10 lines of it
[06:19:59] <zeeshan> if its okay, add another 10 lines
[06:20:06] <zeeshan> eventually the error will pop up :P

[06:20:29] <anarchos2_> it says line 21 of the program
[06:20:35] <anarchos2_> will exceed the limit

[09:07:38] <archivist> have you missed the shop overhead
[09:08:11] <witnit> there is an "other" location i think :)
[09:08:27] <archivist> or is that shop rate
[09:08:30] <witnit> but its not scaled to the rate, just a single cost
[09:08:51] <witnit> no, the rate is for calculation of the estimated price per part
[09:09:13] <witnit> however on that sheet it may need readjusted to function i have not used it in so long
[09:09:25] <witnit> I been cranking out quotes with raw numbers

[09:09:50] <witnit> insane jobs to quote lately
[09:10:04] <witnit> 5 different jobs at the same time each for 100,000 pieces
[09:10:08] <witnit> per month
[09:10:23] <archivist> dont worry about too much
[09:10:41] <archivist> too little is a real problem
[09:11:17] <witnit> yeah but, big numbers in short amount of times is stressful
[09:11:26] <archivist> factor enough in so you can expand the number of machines too
[09:11:58] <archivist> cashflow when expanding is another killer
[09:12:41] <witnit> yes, cashflow becomes problematic when you must order X amount of thousands of pounds of steel then wait to get paid for the job for 90 days after shipment

[09:18:24] <archivist> even though linuxcnc does not understand that concept yet

[09:22:01] <witnit> awesome
[09:22:06] <archivist> still lots to restore and think about, but its in an unheated garage, so waits for funds and summer
[09:22:44] <witnit> I believe you could put wrench flats on a part with that same cutter system
[09:22:58] <witnit> just two saws spaced apart?
[09:23:25] <archivist> may bolt something on it so it can mill like a citizen
[09:23:34] <archivist> one saw
[09:24:05] <witnit> ahh, in davenport I use the same saw type to cut flats
[09:25:12] <witnit> it rotates with the spindle at same rpm while coming in with two circular saws and does it while the part is being turned down
[09:26:19] <archivist> I dont think the cnc world realises that multifunction at the same time idea
[09:27:05] <archivist> some machines are getting close though

[09:59:43] <archivist> I would prefer ISO30 except for tooling costs

[10:06:57] <archivist> there are variations, so you need to be sure first, find a site that shows what the differences are, like http://www.tools-n-gizmos.com/specs/Tapers.html
[10:10:14] <RyanS> I'm pretty sure I don't Want CNC, but I want to have options. If I change my mind. is 3000RPM too slow, or you can compensate with feed rates etc?

[10:21:32] <RyanS> machine says ISO30, M12 drawbar thread. which *seems* to be NMTB ISO according to toolsngizmos
[10:22:10] <witnit> do you have any tooling to go with?
[10:22:42] <RyanS> i dont have a mill
[10:24:34] <RyanS> but its mt3 or iso30 if i get a BF30
[10:25:04] <witnit> tooling is expensive and if you dont have some to go with it, using cnc can reduce your tooling costs. For example instead of buying an adjustable boring bar you can do all size holes with one a single endmill.
[10:26:38] <archivist> cnc may be more sensible as you can write the programs and not rely on your helper
[10:26:49] <RyanS> but still cnc mill is double the price of manual
[10:27:43] <witnit> look up a set of solid carbide endmills .250-1"
[10:29:22] <RyanS> well, i kind of seem to design on the fly so cnc isn't necessarily go to speed things up. I dont think
[10:29:48] <archivist> speed v able to do something
[10:36:10] <RyanS> meh, I am just the design person... I have thought of that and really the only option (I think cnc conversion would take to long) is tormach $16k in my shed... thats going to get me a manual 300x900 lathe,dro. bf30 and a crap load of tooling, plus more

[15:41:09] <robertm> CaptHindsight, a while ago you said "preempt_rt and RTAI are fast enough and easy to use", "preempt_rt is", "also older xenomai". Why the word "older"? Did you mean that newer versions of Xenomai are not fast, or not easy?
[15:43:14] -!- Brunetty has quit [Quit: Que conio hago yo aqui]
[15:43:43] <CaptHindsight> preempt_rt is the easiest to build and use for most people and it's supported by Linuxcnc
[15:44:03] <CaptHindsight> Xenomai isn't currently supported by Linuxcnc
[15:44:23] <CaptHindsight> it's in that UBC branch and machinekit

[15:47:46] <CaptHindsight> the newest version of Xenomai is very similar to preempt_rt, in fact they are pretty much just going that direction

[15:48:50] <CaptHindsight> xenomai was never officially supported by Linuxcnc, it was just in an experimental branch
[15:50:10] <CaptHindsight> the problem with any real time Linux kernels is that the gpu driver and X devs decided to talk to hardware directly

[15:52:44] <CaptHindsight> the newer version of xenomai is preempt_rt, so it is slower
[15:53:19] <robertm> Does the GPU and X people's decision somehow make the "I-pipe" idea not a good idea?
[15:53:49] <CaptHindsight> they just ignored it
[15:54:00] <CaptHindsight> and nobody complained
[15:54:23] <robertm> Who ignored?
[15:54:36] <CaptHindsight> they just wanted to do what they wanted to do, they didn't care about effecting anything real time
[15:54:47] <CaptHindsight> the driver and X devs
[15:54:55] <robertm> But what is the effect?
[15:55:20] <CaptHindsight> more delays
[15:55:26] <CaptHindsight> more jitter

[15:57:52] <CaptHindsight> Xenomai 3 discontinues kernel space APIs
[15:59:27] -!- kwallace has quit [Ping timeout: 264 seconds]
[15:59:38] <robertm> OK, I think I get it. You mean the people who laboriously went through the kernel making everything "safe" for instruction pipelining, now would have to go through lots of graphics driver code too, because the graphics people decided to do their own low-level stuff instead of letting the kernel do it?
[15:59:48] <CaptHindsight> yes
[15:59:58] <CaptHindsight> and X
[16:00:19] <CaptHindsight> there's lots of gpu driver stuff in X now as well
[16:00:56] <CaptHindsight> I wasn't following this evolution so I don't know when it started
[16:01:25] <pcw_home> If you are not doing software stepping it may not matter very much
[16:01:43] <CaptHindsight> yeah, so it could be a lot of work for nothing
[16:02:10] <pcw_home> caching also has a big influence on jitter
[16:02:16] <CaptHindsight> unfortunately the QNX kernel wasn't a model for Linux
[16:02:35] <robertm> And preempt_rt isn't vulnerable to that problem, because it's in the kernel mainline, and any changesets that break it won't get merged in?
[16:02:36] <robertm> I've been planning to do software stepping, but maybe I should reconsider.
[16:03:09] <CaptHindsight> more like turning a minivan into an F1 car vs planning an F1 from the start
[16:04:03] <pcw_home> really depends on how fast you need to step, there are many current MBs that have latencies in the 20 usec region

[16:04:44] <CaptHindsight> we do software stepping set at ~25uS all the time
[16:04:46] <robertm> Is that better or worse than old motherboards? I'm new to all this.
[16:05:08] <pcw_home> I dont think it has changed much
[16:05:37] <pcw_home> I do know Servo thread latency is generally better on faster MBs
[16:05:55] <robertm> When you do 25 us, that's with preempt_rt?

[16:09:03] <CaptHindsight> opening up Firefox tends to really impact the latency test as well as playing a Flash video
[16:09:14] <CaptHindsight> RTAI is dual

[16:12:29] <robertm> CaptHindsight, how big is the impact you see from Firefox and/or Flash?
[16:12:47] <CaptHindsight> often 2x the jitter
[16:14:14] <CaptHindsight> https://github.com/NTULINUX/RTAI this is the latest RTAI that works with Linuxcnc, but you have to build everything from source
[16:15:04] <CaptHindsight> Paulo is currently merging this into the rtai.org tree
[16:16:06] <Rab> CaptHindsight, so is the best configuration for latency to run without any graphics acceleration at all? Eg fbdev?
[16:16:17] <pcw_home> There are a lot of funny caching side effests also (faster threads have lower jitter)
[16:17:18] <CaptHindsight> Rab: since there is video driver stuff in the kernel now and X it doesn't really matter
[16:17:41] <Rab> Ahh, I see
[16:18:06] <CaptHindsight> that's what made it frustration
[16:18:14] <robertm> pcw_home, do those 12 and 18 uS numbers come from a test that shows you the _average_, or the _worst_ that's seen during the test?
[16:18:26] <pcw_home> worst
[16:18:39] <pcw_home> average is quite low
[16:18:48] <pcw_home> is 1-2 usec region
[16:19:40] <pcw_home> You can run the latency histogram to get some insight

[16:23:03] <pcw_home> yes
[16:24:07] <robertm> Do you have an idea of what those numbers might be, instead of 12 and 18, if you used a dual-kernel setup instead of preempt_rt?

[16:31:40] <renesis> is the -20 to 20 a hard axis limit?
[16:31:51] <pcw_home> Yes it show the outliers better but linear gives a good idea of the statistics
[16:32:00] <CaptHindsight> latency testing flash, firefox etc with RTAI was always lower than with preempt_rt
[16:32:16] <pcw_home> no there are a bunch of command line options
[16:32:21] <CaptHindsight> those apps would have an effect on either kernel
[16:32:27] <renesis> cool

[17:56:49] <Bushman> lots of parts are no longer original
[17:57:20] <Bushman> so right now the point is to make it a working tool ;]
[17:58:26] <archivist> mine just after it came home http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_07_Lorch_lathe/IMG_1823.JPG
[18:01:27] <Bushman> heh
[18:01:29] <Bushman> http://bushman.pl/photos/misc/lathe/IMG_0103.JPG
[18:01:44] <Bushman> also the pulley was spinning on the shaft
[18:02:38] <Bushman> the guy selling this pile of junk to me told me the chuck was from this lathe...
[18:02:42] <Bushman> it wasn't: http://bushman.pl/photos/misc/lathe/IMG_0105.JPG
[18:02:55] <archivist> if the belt cover was in front of that, then deliberate and original
[18:03:19] <Bushman> i know
[18:03:50] <Bushman> i've started by trying to make a back plate for the chuck:
[18:03:52] <Bushman> http://bushman.pl/photos/misc/lathe/mount_plate_1.jpg
[18:04:04] <Bushman> http://bushman.pl/photos/misc/lathe/mount_plate_2.jpg
[18:04:23] <Bushman> clamped the chuck backwards to bore the hole for the shaft
[18:04:49] <Bushman> also had to make some ghetto pulley to be able to run it at all
[18:04:59] <zeeshan|2> howd you do that layout
[18:05:01] <zeeshan|2> make a circle
[18:05:11] <zeeshan|2> then find the quadrants
[18:05:18] <Bushman> so one visit the junkyard later:
[18:05:20] <zeeshan|2> then the angles? :)
[18:05:22] <Bushman> http://bushman.pl/photos/misc/lathe/pulley01.jpg
[18:05:49] <Bushman> the bolts on the back of the chuck?
[18:05:58] <Bushman> lemme see...
[18:06:28] <Bushman> radius
[18:07:29] <Bushman> i made a hexagon with calipers using radius of the circle
[18:07:44] <Bushman> then used 3 of the points
[18:08:09] <Bushman> at least i think i did it this way... i really can't remember lol
[18:08:36] <Bushman> yup... you can see the score marks

[19:13:55] <JT-Shop> yea
[19:14:32] <JT-Shop> I'm thinking I just need the plate and the feeder thing to print parts on my BP
[19:14:42] * JT-Shop is getting into casting
[19:14:43] <malcom2073> Repetier is both a software on the PC to send gcode, and a firmware on an arduino to run the printer.
[19:14:58] <malcom2073> A BP will be able to print, albiet 5-10 times slower than a small printer
[19:15:03] -!- karavanjo has quit [Ping timeout: 264 seconds]
[19:15:11] <malcom2073> and it won't do very good qualitywise, but since you're casting you can machine it after anyway
[19:15:55] <malcom2073> You can treat the extruder as a 4th axis, which is what I do on my printer (runs machinekit), but that's really not optimum
[19:15:59] <JT-Shop> why would the BP have less quality than a $300 printer?
[19:16:10] <JT-Shop> ah ok
[19:16:14] <malcom2073> Speed is key, the slower you print, the more the parts cool down as you're printing
[19:16:18] <malcom2073> you want to lay hot plastic on hot plastic
[19:16:33] <JT-Shop> how fast do the machines go?
[19:16:44] <malcom2073> between 30-100mm/sec is typical
[19:16:49] <malcom2073> no clue what that is in inches a minute, sorry
[19:17:03] <malcom2073> But they also can reverse direction near immediatly
[19:17:06] <malcom2073> at those speeds
[19:17:36] <JT-Shop> 70 IPM to 230 IPM
[19:18:04] <JT-Shop> because of the light weight gantry?
[19:18:12] <malcom2073> Yeah
[19:18:21] <malcom2073> Proper machine for proper purpose. Tbh if you want to fiddle with it, pay the $300 for a printer, build it up, and play, you'll find uses for it
[19:19:12] <malcom2073> You'll have $50 for a heated bed setup, $100 for a proper extruder/hotend, plus an extra stepper driver to run it, brackets to attach it to the BP
[19:19:14] <malcom2073> etc etc
[19:20:06] <JT-Shop> have you looked into any of the printer kits?
[19:20:32] <malcom2073> I've looked into some of them, I wound up buying a kit for way too much, then going and designing/building my own after not being satisifed with the current offerings heh
[19:21:24] <malcom2073> It's another hobby getting things to print right, but if you're only using it occasionally and not trying to actually *produce* things with it, a cheapie kit (like a printrbot?) should do fine
[19:21:29] <JT-Shop> what were you not satisfied with?
[19:21:49] <malcom2073> The big thing was the flimsyness of it.
[19:22:06] <malcom2073> I hated that when I had the speed too fast, it would show "wobbles" in the print from the whole frame flexing
[19:22:06] <JT-Shop> yea, some look rather weak
[19:22:25] <malcom2073> Didn't really affect the strength of the print, just made it look odd
[19:22:27] <JT-Shop> http://www.vetco.net/catalog/product_info.php?products_id=15179&gclid=CIb5q-j5vsMCFYWUfgodOC0ABg

[19:23:35] <JT-Shop> where does he hang out at?
[19:24:10] <malcom2073> heh, #reprap
[19:24:24] <JT-Shop> that makes sense lol
[19:24:53] <malcom2073> his name is Branden or something like that, he's not there now, he usually is in the afternoons EST though
[19:25:08] <malcom2073> I'll point him in your direction next time I see him if you want
[19:25:33] <JT-Shop> ok thanks
[19:26:08] <JT-Shop> yikes 560 total there

[19:39:21] <tjb1> Would not recommend that

[19:39:55] <JT-Shop> what do you recommend?
[19:40:05] <tjb1> What are you looking for?
[19:40:08] <JT-Shop> I noticed the part edges are kinds lumpy

[19:42:47] <tjb1> yes
[19:43:04] <tjb1> Why are you not building your own?
[19:43:08] <JT-Shop> is there plans for that or did you dream it up?
[19:43:21] <tjb1> There are plans but it requires a lot of printed parts
[19:43:25] <JT-Shop> just getting interested when I saw that thread
[19:43:33] <tjb1> Probably around $700 for the delta
[19:43:37] <JT-Shop> can they be machined?
[19:43:53] <tjb1> some of them could
[19:44:00] <tjb1> not easy

[19:49:15] <JT-Shop> yea
[19:49:22] <tjb1> no, I designed that one
[19:49:28] <JT-Shop> nice
[19:50:16] <JT-Shop> so it's similar to the K8200
[19:50:27] <tjb1> well the extruder moves in X direction

[19:51:40] <JT-Shop> what software are you using on the last one
[19:52:03] <tjb1> controller runs marlin, repetier host is sending the code

[19:58:33] <PetefromTn_> but I got some of the same quarter inch tubing I used for the refridgerator water line
[19:58:55] <PetefromTn_> it is the nylon type semi opaque stuff pretty rigid for plastic tubing.
[19:59:03] -!- FreezingCold [FreezingCold!~FreezingC@135.0.41.14] has joined #linuxcnc
[19:59:25] <PetefromTn_> and I got a quarter inch flared fitting to go from the pump fitting to the hose
[19:59:32] <JT-Shop> tjb1, like this one http://www.reprapdiscount.com/electronics/11-taurino-power.html
[19:59:37] <PetefromTn_> from there on I got put connect fittings
[19:59:49] <tjb1> yes
[19:59:50] <PetefromTn_> tees, unions, Y's and a ball valve
[20:00:25] <PetefromTn_> gonna eat some lunch here and see about putting it together to see if it will hold vacuum or not.
[20:00:37] <tjb1> JT-Shop: This would be a decent kit to get - http://www.reprapdiscount.com/home/20-ultimate-power-pack.html
[20:00:55] <PetefromTn_> I am gonna order a small vacuum gauge online along with some of that rubber linear O-ring material for the seal gland on the fixture
[20:01:06] <tjb1> JT-Shop: This one better http://www.reprapdiscount.com/home/29-ramps-14-ultimate-power-kit-1-wiring-set-capable-of-24v.html
[20:01:48] <PetefromTn_> I have a broken or rather stripped out magnetic base here I am hoping to turn into a block I can set on the mill table that holds the ball valve and the gauge
[20:02:04] <PetefromTn_> so it is easier to turn it all on and off and monitor the vacuum
[20:02:45] <PetefromTn_> I was thinking of a little manifold block from aluminum that has the guage and the ball valve in and out that I can screw down to the mag base
[20:03:16] <PetefromTn_> this should be a decent enough start to the system and will hopefully allow me to start work on the parts I need to make this week.

[20:28:42] <zeeshan|2> PetefromTn_: seriously
[20:28:45] <zeeshan|2> im just gonna make a drawbar
[20:28:50] <zeeshan|2> and use it manually for now.
[20:28:55] <zeeshan|2> itll suck, but gotta do what i gotta do
[20:29:15] <zeeshan|2> i have 5/8 threaded rod
[20:29:16] <shaun413> ?
[20:29:17] <PetefromTn_> that would indeed suck but if it is not anything else you can do
[20:29:26] <zeeshan|2> just screw it in
[20:29:28] <zeeshan|2> and all it a day :P
[20:29:52] <PetefromTn_> it would allow you to continue with fine tuning the drives and maybe make some chips !
[20:30:11] <zeeshan|2> yes
[20:30:12] <PetefromTn_> then you could screw with the cylinder when you get a chance
[20:30:15] <zeeshan|2> dude, i dont physically see
[20:30:21] <zeeshan|2> how they can stack enough belleville washers in the cylinder
[20:30:26] <zeeshan|2> to provide enough clamping force
[20:30:36] <zeeshan|2> i think ill email these guys
[20:30:39] <zeeshan|2> and ask them if they make a replacement or something
[20:30:43] <PetefromTn_> belleville stacks can come in different sizes for sure
[20:31:11] <PetefromTn_> mine are quite wide diameter and the stack is kinda short but they are THICK
[20:31:24] <zeeshan|2> Ah.
[20:31:30] <shaun413> anyone?
[20:31:43] <PetefromTn_> but most that are not large diameter are a lot more washers and tall
[20:34:20] <PetefromTn_> zeeshan|2 Hey man I was thinking about you yesterday LOL
[20:34:40] <PetefromTn_> about this lathe retrofit
[20:35:49] <shaun413> are nema17 usefull for anything?
[20:36:19] <witnit> if they sell it, they have a use :)
[20:36:29] <shaun413> ?
[20:36:30] <pcw_home> small things :-)
[20:36:36] <shaun413> IE?
[20:36:51] <zeeshan|2> PetefromTn_: sup
[20:36:57] <pcw_home> very common on 3D printers
[20:37:08] <zeeshan|2> shaun413: why dont you go troll reprap
[20:37:09] <shaun413> yes thats what its from
[20:37:19] <shaun413> I want to repourpose it
[20:37:26] <pcw_home> teeny weeny desktop mills
[20:37:35] <shaun413> will it actually mill things?
[20:37:42] <PetefromTn_> yeah I was thinking about the lathe retrofit
[20:37:58] <PetefromTn_> and I REALLY want to get a pneumatic 5c collet closer built or bought for it.
[20:38:05] -!- skorasaurus has quit [Quit: WeeChat 1.0.1]
[20:38:07] <PetefromTn_> been looking at ideas and existing designs
[20:38:21] <PetefromTn_> I know your lathe can use one too ;)
[20:38:24] <pcw_home> given enough leverage (gearing), anything is possible
[20:38:29] <witnit> any motor will work with proper gearing
[20:38:42] <witnit> just slower.
[20:39:41] <zeeshan|2> yea PetefromTn_would be nice :)
[20:39:44] <PetefromTn_> I THINK I can make something that uses automotive tapered roller bearings and an O-ringed piston setup for the clamping..
[20:40:33] <PetefromTn_> I will definitely have one on my machine as I really want to be able to automate small collet parts machining with a puller etc.
[20:42:01] <witnit> pete you can make an airloader for a single spindle for about $40
[20:42:04] <PetefromTn_> the end of my spindle is much like yours just a smooth tube with flat end just need to make a bearing cap mount there and something a floating clamp piston setup and then a tubular drawbar with an adjustble end.
[20:42:23] <PetefromTn_> airloader?
[20:42:27] <witnit> yeah
[20:42:35] <witnit> air behind the bar
[20:42:48] <PetefromTn_> what I am most interested in is something like the royal products pneumatic collet closer system
[20:43:27] <witnit> so take, like steel pipe, grey pvc liner, bearing and slug with leather seals and a about 20lbs behind it open the collet and it feeds out
[20:43:29] <PetefromTn_> the biggest challenge is making the floating union that allows you to hookup the air lines and valving
[20:43:42] <witnit> use a taper cone in the end of the slug to keep the bar centered
[20:43:57] <PetefromTn_> it is a relatively simple design really but it needs to be pretty concentric so it does not wobble like a bitch
[20:44:49] <PetefromTn_> actually I was thinking of capturing the OD of the spindle body so I can use the thickes drawbar tube possible for rigidity of the threads on the collet end

[20:47:13] <PetefromTn_> was thinking about a machine fitting that goes on the end of the drawbar tube that has a shoulder on the other side to accept the female bearing race
[20:48:36] <PetefromTn_> then the floating union would be just a shop built pneumatic piston assembly with bosses on each side to accept the male bearing part and then another boss that is mounted to the tubular drawbar that is threaded to the OD of the tube and then a pair of finger nuts to adjust the drawbar dead length etc.
[20:50:07] <witnit> what machine is this?
[20:51:11] <PetefromTn_> this will be for a Standard Modern 1440CNC lathe I am retrofitting to linuxCNC/Mesanet

[22:16:33] <zeeshan|2> bobo_: yea spanner worked
[22:16:46] <zeeshan|2> what you do is put a sacraficial bolt
[22:16:50] <zeeshan|2> where the hat used to mount
[22:16:55] <zeeshan|2> and jam the spanner wrench against it
[22:17:03] <zeeshan|2> you'll destroy the bolt in the process, but it will loosen
[22:17:09] <zeeshan|2> then just replace bolt
[22:17:30] <zeeshan|2> so yea, i am using a manual drawbar now
[22:17:32] <zeeshan|2> :)
[22:17:37] <zeeshan|2> major down grade
[22:20:08] <skunksleep> zeeshan|2: figured out the issue with the spindle?
[22:20:48] <zeeshan|2> skunksleep: not 100%, but deduction leads me to believe the spring pack inside the hydraulic cylinder is nfg
[22:20:54] <zeeshan|2> cause there is not enough clamping force
[22:21:20] <skunksleep> Ah. It is a start.
[22:22:52] <skunksleep> The belvel washers on the k&t are huge
[22:23:27] <zeeshan|2> http://c1.staticflickr.com/9/8642/16412452615_ee07cc4ad3_h.jpg
[22:23:36] <zeeshan|2> im really surpised to find there are no belleville washers here
[22:24:26] <zeeshan|2> Zeeshan, This should be 12000 newtons/2700 lbs. this drawbar should have the balls and wedge rings all replaced. We can rebuild this at our facility and test/certify it or supply you all of the needed parts. New springs will help but not solve the problem
[22:26:58] <zeeshan|2> okay so its definitely messed :)

[22:33:08] <bobo_> zeeshan so, " new springs will help but not solve problem " ? what is this about ? fingers and draw rod --have streatched ?
[22:34:03] <zeeshan|2> bobo_: i guess they use a wedge inside the cylinder
[22:34:07] <zeeshan|2> which will wear over time
[22:34:13] <zeeshan|2> prolly using it as a multiplier of force.
[22:34:24] <zeeshan|2> i read in a thread that its not just belleville washer force
[22:34:34] <zeeshan|2> there is cam/wedge action that happens
[22:35:04] <zeeshan|2> so when it clamps, the springs expand, and after a certain displacement, the cam/wedge locks into place
[22:35:13] <zeeshan|2> so even if the springs failed during machining
[22:35:21] <zeeshan|2> the cam/wedge lock would stop the tool from flying out
[22:35:37] * zeeshan|2 doesnt understand it full and doesnt want to
[22:35:42] * zeeshan|2 will send it to get rebuilt
[22:35:47] <zeeshan|2> im sure itll be like 400-500 bux
[22:35:53] <zeeshan|2> which is worth me not fucking around with it
[22:36:06] <bobo_> must be a small sized cam/wedge . some watch stuff ?
[22:36:34] <zeeshan|2> do you remember the two drawings i posted?
[22:36:39] <zeeshan|2> one of the internals of the cylinder
[22:36:44] <zeeshan|2> look at where the 6.2mm ball is
[22:36:47] <zeeshan|2> you can see the wedge there
[22:36:52] <zeeshan|2> where the ball rides on
[22:37:09] <zeeshan|2> and the impression where the ball rests

[22:45:59] <zeeshan|2> lol
[22:46:00] <zeeshan|2> no
[22:46:48] <PetefromTn_> just ordered a little chrome vacuum gauge so I can monitor the vacuum on this stuff while I am machining it.
[22:46:55] <zeeshan|2> PetefromTn_: pretty much any of those will work
[22:47:01] <PetefromTn_> yeah I know
[22:47:11] <zeeshan|2> so why ask
[22:47:12] <PetefromTn_> I was thinking it should probably be kinda soft
[22:47:25] <PetefromTn_> like maybe 40 or 60 durometer
[22:47:33] <zeeshan|2> get the softest one

[22:48:19] <PetefromTn_> and they use a neoprene chord
[22:48:35] <PetefromTn_> no specifics I could find on diamter or durometer
[22:49:09] <zeeshan|2> well the bigger the diameter
[22:49:13] <PetefromTn_> http://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=31185
[22:49:21] <zeeshan|2> the better the seal
[22:49:27] <PetefromTn_> I would think so too
[22:49:43] <zeeshan|2> the most important thing
[22:49:45] <PetefromTn_> not sure if I want to use like 3/16 or quarter inch stuff or not
[22:49:46] <zeeshan|2> is the groove design
[22:49:56] <zeeshan|2> you can get a 50A durameter o-ring
[22:50:02] <zeeshan|2> and ahve the groove too tight
[22:50:09] <zeeshan|2> itll seal, but not as good
[22:50:35] <zeeshan|2> how thick will your fixture be?
[22:50:50] <PetefromTn_> this dedicated one will be half inch thick
[22:51:03] <zeeshan|2> groove depth is approx 60-80%
[22:51:08] <zeeshan|2> of o-ring cross section
[22:51:09] <PetefromTn_> it is going to be for some relatively light machining
[22:51:28] <zeeshan|2> so you'll be fine with 1/4" too :P
[22:51:37] <zeeshan|2> but then you'll get limited by your bend radius
[22:51:42] <PetefromTn_> probably 3/16 might be a good choice
[22:51:55] <zeeshan|2> yea
[22:52:03] <PetefromTn_> my friend art made one and used 1/8 inch rod
[22:52:07] <zeeshan|2> i machined 1/16" oring grooves for my steam engine
[22:52:10] <zeeshan|2> and that was no fun
[22:52:12] <zeeshan|2> broke so much shit
[22:52:24] <zeeshan|2> cause the machine only went upto 6000 rpm
[22:52:35] <zeeshan|2> and had like .0003" runout
[22:53:08] <PetefromTn_> http://www.tormach.com//uploads/images/Gallery/products/workholding/Vacuum_Table/vacuum_table.jpg
[22:53:11] <renesis> seems fine for an oring groove?
[22:53:34] <renesis> 2L makes a little vacuum table setup
[22:53:47] <zeeshan|2> PetefromTn_: can't wait to see yours in action
[22:53:52] <PetefromTn_> that plate is 17.75 by 9.5"
[22:53:52] <zeeshan|2> that will be so sweet to have for thin stuff.
[22:54:06] <PetefromTn_> you and me both man hehe
[22:54:18] <PetefromTn_> I am excited about this have been wanting it for awhile now
[22:54:27] <zeeshan|2> are you going to use a ball nose end mill
[22:54:33] <zeeshan|2> to do all those grooves
[22:54:37] <PetefromTn_> so if that plate is that big the gasket is probably at least quarter inch
[22:54:45] <zeeshan|2> or just regular slot end mill
[22:54:59] <PetefromTn_> for this dedicated fixture it will not be that grid pattern
[22:55:08] <zeeshan|2> ah okay
[22:55:18] <zeeshan|2> jeez
[22:55:19] <PetefromTn_> I am going to design the plate to be the shape of the part just inside the outer edge
[22:55:21] <zeeshan|2> they want 1k for that plate
[22:55:22] <zeeshan|2> hahaha
[22:55:34] <PetefromTn_> yeah it is kinda crazy what they want for vacuum chucks
[22:55:47] <zeeshan|2> that looks like maybe 1hr of machining at most
[22:56:04] <zeeshan|2> maybe 10 hours using a tormach
[22:56:08] <zeeshan|2> thats why so high priced!

[22:56:18] <renesis> http://www.2linc.com/Vac_Vise_workholding.htm
[22:56:19] <PetefromTn_> I wonder what the bottom looks like
[22:56:28] <renesis> ha, vacuum chuck for your vise
[22:56:37] <PetefromTn_> is it just a solid plate and has the grid patter and tapped holes for multiple hoses or what?
[22:56:38] <zeeshan|2> looks like theyve got 2 keys
[22:56:47] <zeeshan|2> to go onto the t-slot
[22:56:48] <renesis> theyre like $750/ea =\
[22:56:56] <zeeshan|2> and a long gun drilled hole
[22:57:01] <zeeshan|2> connecting all the ports.
[22:57:46] <renesis> seems kinda lossy compared to an open design
[22:57:58] <PetefromTn_> there is a photo of it on the machine and you can see the vacuum line coming in from the long edge
[22:58:39] <zeeshan|2> wtf
[22:58:42] <PetefromTn_> so it must be either two pieces together or something like that. would be hard to machine the grid of ports holes from a solid piece
[22:58:46] <zeeshan|2> they want 587$ for that vac pump
[22:58:51] <zeeshan|2> thats the same hf vac pump
[22:59:02] <PetefromTn_> and it looks identical to the HF pump I just got.

[23:06:27] <PetefromTn_> actually my favorite T-shirt is a margaritaville one I got in Key west and it is yup you guessed it....
[23:06:35] <renesis> because red = war
[23:07:03] <XXCoder> no because pink is bold, male color while blue is mellow color
[23:07:08] <renesis> but yeah whatever fuck pink
[23:07:10] <XXCoder> then somehow it reversed
[23:07:14] <PetefromTn_> I could care less what freakin' color it is, never had a better shave and that is after trying quite a few manly ones hehe
[23:07:56] <renesis> honestly, those big bags of bic razors prob the best way to go
[23:07:58] <PetefromTn_> I honeslty think I am gonna steal her stash of razors and tell her they were stolen while I was out in the shop tinkering LOL
[23:08:04] <renesis> just use two or three every shave
[23:08:11] <renesis> prob still come out ahead in terms of money
[23:08:22] <XXCoder> renesis: or resharp em like I do
[23:08:31] <XXCoder> my $2 for 20 razors last around month
[23:08:41] <XXCoder> then usually plastic breaks somewhere
[23:08:43] <renesis> thats a lot of razors fuck
[23:09:21] <XXCoder> I mean, ONE lasts a month or so. average is year per bag due to few razors breaking after only a week
[23:09:50] <renesis> oh damn
[23:10:14] <PetefromTn_> screw that noise single edge razors SUCK.. the ones I have been using have three blades and I thought they were the shit but after using hers this morning I am sold.
[23:10:14] <XXCoder> (repeat) just run razor backwards down arm, it will resharp. thats how mine lasts so long
[23:10:26] <XXCoder> mines 2 edge type
[23:10:45] <bobo_> pete look outside , notice the lack of grass ? don't mess with the ladies razor !

[23:11:06] <PetefromTn_> it seemed like it is harder to cut yourself too with her blades..
[23:11:24] <XXCoder> easier to shave large complex shape (legs) with em
[23:11:29] <XXCoder> without cuts
[23:11:45] <XXCoder> well would guess thats why their tech advanced more than mens lol
[23:11:46] <PetefromTn_> I know it sounds funny but I am serious it was like the best shave ever
[23:12:17] <renesis> yeah i dunno what the deal is
[23:12:23] <XXCoder> yeah I belive you
[23:12:30] <PetefromTn_> Oh my wife just woke up from her nap...
[23:12:45] <PetefromTn_> she said they are called venus razors

[23:29:19] <andypugh> I have never used a razor.
[23:29:22] <tjtr33> PetefromTn_, put a Sun Tacho on the motor
[23:29:33] <Jymmm> andypugh: straight razor?
[23:29:52] <andypugh> I used an electric shaver for a while, then I stopped shaving.
[23:30:00] <Jymmm> ah
[23:30:13] <PetefromTn_> if I did that I would look like grizzly adams overnight LOL
[23:30:21] <Jymmm> I'm thinking about a safety razor, just not sure yet.
[23:31:01] <andypugh> Anyway, more importantly, O-ring groves shoild not be circular, they should be square. The O-ring material is soft but incompressbile, it needs somewhere to squish to.
[23:31:22] <Jymmm> I never thught of that.
[23:31:47] <XXCoder> heh I can't grow a beard basically
[23:31:50] <andypugh> If you look at the O-ring groove design guides it’s pretty clear.
[23:31:53] <XXCoder> best I can do is nice bum look
[23:32:07] <XXCoder> my family genes dont give us nice beards
[23:32:36] <Jymmm> andypugh: Shit, I BARLY have an o-ring sizing chart, and that's only becasue I found a local company that ONLY sells orings and nothing else.
[23:32:38] <andypugh> I normally have a really short beard, but last year I left it 6 months and ended up looking properly victorian.

[23:34:32] <andypugh> You will see every groove is sort-of square

[23:46:45] <PetefromTn_> no it is a home-machinist- no so budget..CHINESE machine manufacturer that does a pretty good job of polishing the chinese turds into something usable and basically sells a lot of nice options for them and happens to use LinuxCNC for their machines.

[23:49:19] <bobo_> Pete $700 to me doese't' sound like a over the top price for a new computer
[23:49:52] <XXCoder> hey LeelooMinai hows your project

[23:50:08] <XXCoder> the router one'
[23:50:12] <PetefromTn_> GREAT....tell you what, you buy the computer and let us have the LinuxCNC software for the lathe that is on it :)

[23:51:21] <PetefromTn_> that is a stretch
[23:51:24] <LeelooMinai> XXCoder: SLowly going forward. I made holes for the spindle bracket today. Have the spindle and table is almost ready to assemble. Need to buy some socket screws and slamp set, and what's left will be VFD - probably will buy it next month.
[23:51:37] <XXCoder> cool :)
[23:51:39] <LeelooMinai> clamp*
[23:52:59] <PetefromTn_> but yeah I must give them credit they competently straddle the gap between true chinese junk bedmills and commercial CNC equipment pretty well. And they have come up with some interesting designs for tooling and options for all of thier machines.

[23:53:35] <LeelooMinai> I was just checking out their TTS system of what they call it - seems useful.
[23:54:24] <LeelooMinai> I saw some guys on youtube using it with some automatic changer attachement - must be nice for someone who makes a lot of parts.
[23:54:25] <PetefromTn_> yeah it actually is pretty decent. I had a BUNCH of it when I had my RF45 CNC conversion running. No complaints at all really. It is a good option for smaller lower HP mills.

[23:55:31] <LeelooMinai> Are there some pneumatics that suck those tools in? I heared strange noise when they were3 replacing them.
[23:56:32] <PetefromTn_> yeah the drawbar uses a belleville stack to suck the collet into the spindle with like 1500 lbs of force as I recall and they use pneumatic cylinder to release it.

[23:58:43] <PetefromTn_> no thanks I don't have that kind of time. My only real interest in Tormach products is what they have done with the new Slant Pro Lathe LinuxCNC interface. It looks very nice.
[23:59:40] <LeelooMinai> DO they back-contribute some code?
[23:59:56] <bobo_> I thought novakon has a slant bed lathe also
