[08:32:04] <archivist> skunkworks_, I bet I get ripped of some more soon, another 대식 주 has subscribed to you on YouTube email
[08:33:05] <skunkworks_> yeck
[08:34:07] <archivist> I wonder if they are all looking for high hit count videos
[08:34:55] <archivist> I wish I knew why that video has so many more hits that the others
[08:52:58] <skunkworks_> Probably.. But why not pick higher count ones like justin beber or such..
[08:53:34] <archivist> dmca smack downs would probably be larger and faster
[08:53:39] <eric_unterhause1> we have a really high hit count vid about diamond turning
[08:53:56] <eric_unterhause1> high hit count for machining vids that is
[08:54:05] <archivist> count ?
[08:54:15] <cradek> archivist: which one?
[08:54:23] <eric_unterhause1> I'll find it
[08:54:41] <eric_unterhause1> couple hunnerd thousand

[08:56:11] <archivist> wee didnt know I was up to 600k :)

[08:56:43] <Tecan> (vAvfrrlMZg4) "Diamond Turning Copper Sample with Measurements.wmv" by "mdrlpsu" is "Tech" - Length: 0:01:30
[08:58:16] <cradek> archivist: huh, not even any sound
[08:58:26] <eric_unterhause1> don't think sound matters
[08:58:32] <cradek> maybe 600,000 people have broken bread machines
[08:58:44] <skunkworks_> heh
[08:58:59] <archivist> or helical gear
[08:59:09] <eric_unterhause1> since no other vids get anyhits, maybe it would be better with sound
[08:59:32] <archivist> but amazing view count for such a crappy vid
[09:00:02] <eric_unterhause1> last week I ordered stuff from sparkfun for my bbb and decided to get steppers for my shapeoko
[09:00:10] <skunkworks_> my highest view count is 12k
[09:00:19] <eric_unterhause1> next day, my son asked me if we could work on the shapeoko
[09:00:23] <skunkworks_> https://www.youtube.com/watch?v=vNn-Yr7it5s
[09:01:01] <eric_unterhause1> skunkworks_ way to get your hit count up by 10
[09:01:12] <skunkworks_> heh
[09:01:26] <eric_unterhause1> how come the Tecan bot didn't say what the title was?
[09:01:35] <skunkworks_> https

[09:02:03] <eric_unterhause1> did you do https on purpose?
[09:02:14] <eric_unterhause1> Tecan probably gives you an extra hit :)
[09:02:37] <skunkworks_> I was logged into youtube.. that is what it does..
[09:03:14] <archivist> I should have joined the advertising thing...might have an extra pound in my pocket
[09:04:59] <skunkworks_> eric_unterhause1, do you do optics?
[09:07:04] <archivist> any way for some relaxation

[09:17:32] <GammaX-Shop> mornin all
[09:24:14] <Valen> archivist: one of my friends got 100,000 odd hits on a youtube video of him showing how to balance carbies, he got a cheque for like $150
[09:26:08] <Loetmichel> Valen: out of thin air or with some "companion program" or anything?
[09:26:24] <Valen> he signed up for the advertising thing
[09:26:29] <Loetmichel> ah
[09:27:46] <Valen> there any reason one cant put a plasma cutter head onto a tig welder?
[09:28:45] <Valen> yes, the voltage is too high :-<
[09:29:35] <toastydeath> plasma cutters need a hf/hv source
[09:29:47] <toastydeath> as well as the lv/hc source
[09:31:51] <Loetmichel> toastydeath: a plasma cutter needs the HF/HF only for starting, nike good Tig welders already have
[09:32:03] <Loetmichel> so i dont see why not, if the voltages/currents fit
[09:32:20] <Valen> sounds like they run around 90 volts or so
[09:32:24] <Valen> tig is more like 20
[09:32:29] <Loetmichel> IIRC there ARE combination tig/mig/mag/ plASMA WELDERST
[09:32:37] <Loetmichel> WHERE YOU CAN CHANGE THE HEAFS
[09:32:44] <Loetmichel> ups.. capsloc
[09:32:55] <Valen> yeah i'm picking one up for a friend tomorrow
[09:33:10] <Valen> I was just wondering about sticking a plasma torch on our existing tig
[09:33:15] <Loetmichel> mma also ;-)
[09:33:37] <Loetmichel> may not work because of the regulating enlectronics
[09:33:53] <Loetmichel> but should be possible in prinzipe
[09:34:15] <Valen> I think its down to using air as the working gas
[09:34:28] <Valen> to plasmafy air requires lots more volts than argon
[09:34:43] <archivist> Valen, hmm interesting :)
[09:35:00] <toastydeath> oh that's true, i forgot that most tig welders have hf start
[09:36:15] <Loetmichel> Valen: if you feed the plasma with argon: why not?
[09:36:15] <Valen> hmm this looks like it could do the job
http://www.youtube.com/watch?feature=player_detailpage&v=2OjEhGHit84#t=111s
[09:36:16] <Tecan> (2OjEhGHit84) "cutting with a tig torch" by "weldingtipsandtricks" is "Tech" - Length: 0:03:55
[09:36:24] <Valen> argon is spendy
[09:36:32] <Loetmichel> thats right
[09:37:11] <Valen> I have used CO2 to "cut" with a tig torch in the past
[09:39:32] <Loetmichel> thts th reason i used beer gas from the pub suppier for mag welding in my days ;-)
[09:39:39] <Loetmichel> (pure c02)
[09:39:51] <Loetmichel> MUCH cheaper than corgon or argon
[09:40:03] <Loetmichel> and with mild steel : same result ;-)
[09:50:37] <JT-Shop> dang Tennessee is long
[09:58:28] <jdh> JT: no kidding
[09:59:48] <JT-Shop> most of my day tomorrow will be driving across Tennessee
[10:00:01] <jdh> 40 all the way?
[10:00:09] <JT-Shop> and most of the next day will be coming back
[10:00:31] <jdh> I drove home from Nashville yesterday.
[10:00:32] <JT-Shop> come in on 24 then 40
[10:01:26] <jdh> heh, you will miss 1/3 of TN then
[10:01:54] <JT-Shop> I'll make that up in MO, IL, and KY
[10:02:24] <jdh> stick it on a pallet and ship it!
[10:02:30] <JT-Shop> I'm pretty much due north of Memphis
[10:03:04] <jdh> 900 miles from here to memphis on I40 and I'm in the next state.
[10:03:41] <JT-Shop> 668 miles from me to my dest in Matthews NC
[10:04:36] <jdh> geez... that's on the wrong side of charlotte also.
[10:04:40] <jdh> only about 3 hrs from here.
[10:05:03] <JT-Shop> yea, at least I don't have to drive far to my sisters house in Concord for a nap
[10:06:06] <JT-Shop> google map shows me going straight through Charlotte but I'm thinking 485 around the south of Charlotte
[10:06:09] <jdh> there is no good way to get to matthews from anywhere west
[10:08:04] <JT-Shop> what's the least painful way?
[10:08:50] <jdh> fly in to charlotte, rent a vehicle
[10:10:15] <JT-Shop> be hard to haul a trailer back on the plane
[10:10:42] <jdh> 40-26-85 are all interstate. 40-26-US74 is shorter and 74 isn't too bad
[10:11:09] <JT-Shop> it shows me taking 74
[10:11:19] <GammaX-Shop> JT-Shop: what u picking up?
[10:11:23] <jdh> 40-77 is all interstate, but out of the way.
[10:11:27] <JT-Shop> RT622
[10:11:37] <JT-Shop> I'm looking for the fastest route
[10:12:01] <GammaX-Shop> y you hauking it back and not riding it?
[10:12:20] <JT-Shop> is 74 through Charlotte the best route
[10:12:40] <JT-Shop> I'm tossing it in the back of my truck
[10:13:05] <jdh> depends on the time. I'd take 485 south around charlotte
[10:13:17] <JT-Shop> it will be 4pm ish
[10:13:20] <jdh> heh
[10:13:32] <JT-Shop> that didn't sound good
[10:13:56] <jdh> charlotte is sprawling and has lots of area traffic
[10:14:35] <jdh> 74 in until you get to 85/485 south then around the outside.
[10:14:46] <JT-Shop> GammaX-Shop:
http://www.spyder.brp.com/gears-and-accessories/spyder-trailer
[10:15:06] <JT-Shop> ok, that sounds like a plan
[10:15:49] <GammaX-Shop> y so far?
[10:15:53] <jdh> I guess it is really 85 North when you first hit it until you get to 485
[10:16:44] <JT-Shop> yea that makes sense cause it goes north out of Charlotte
[10:17:08] <JT-Shop> new old stock 1/2 price and color matches
[10:17:52] <jdh> 74 goes all the way in through charlotte, but there are thousands of stop lights for the 30 miles on either side of charlotte
[10:18:15] <JT-Shop> that would suck in the afternoon I'd bet
[10:19:04] <jdh> it may only be hundreds, but it certainly feels like thousands
[10:20:35] <JT-Shop> I just checked my GPS in the truck and it has me taking 485 so I don't have to putz with that
[10:21:29] <jdh> you can do 74 to 485, or 74 to 85 to 485
[10:23:52] <JT-Shop> I'm guessing it would be better to pick up 85 when 74 crosses it and skip Gastonia
[10:25:11] <jdh> yeah, gastonia is about where the traffic lights start
[10:29:56] <jdh> I'd probably skip 74, its frustrates the hell out of me. I26 to I85 is probably only a few miles longer and has no stops.
[10:32:58] <JT-Shop> it shows that it is only 14 miles longer to take 26 to 85
[10:33:42] <JT-Shop> no, it lied
[10:34:12] <Tom_itx> we always take 40
[10:34:26] <jdh> to charlotte?
[10:34:30] <Tom_itx> yeah
[10:34:40] <Tom_itx> cut north i forget what road
[10:35:08] <Tom_itx> straight to okc then N
[10:35:36] <jdh> S
[10:41:04] <Tom_itx> i think we went s at statesville
[10:41:26] <Tom_itx> or maybe hickory
[10:44:42] <Tom_itx> fun goin thru those hills at 4am
[10:46:54] <IchGuckLive> hi all B)
[10:49:37] <GammaX-Shop> Im thinkin about makin a youtube channel and dedicate it to linuxCNC tutorials... Start out basic and go on to bigger and better from there...
[10:49:44] <GammaX-Shop> hey IchGuckLive hows it goin
[10:50:45] <IchGuckLive> GammaX-Shop: rain rain and rain again 74l since yesterday here
[10:51:08] <GammaX-Shop> damn! IchGuckLive where you live?
[10:51:16] <IchGuckLive> Germany
[10:52:08] <IchGuckLive> GammaX-Shop:
http://www.youtube.com/user/magic33de/videos
[10:52:20] <IchGuckLive> you have seen ma channel full of linuxcnc
[10:55:00] <IchGuckLive> GammaX-Shop: i got a 5 part tutorial there for Germans
[10:56:42] <IchGuckLive> GammaX-Shop: be awar of smaming your acount on questiuons you might not like in all languages of Mach freaks
[10:57:53] <IchGuckLive> GammaX-Shop: ?
[11:02:24] <GammaX-Shop> sorry
[11:02:40] <GammaX-Shop> lol mach freaks hate on us im sure
[11:03:48] <IchGuckLive> for my experience its a 90/5 percent on homemaschineing to mach
[11:04:24] <IchGuckLive> so they just ask you to get you in a other mind about 50-200 a week
[11:10:30] <GammaX-Shop> lol
[11:22:23] <IchGuckLive> im off by
[12:46:22] <jdh> squirt some soapy water on it, look for bubbles
[12:46:33] <jdh> or just submerge it if you can
[12:48:04] <Gigs-> It's kind of offtopic but can someone help me with tig fittings?
[12:48:36] <Gigs-> As far as I can tell, the tank I have access to has "B" sized female output on its regulator, but it's a mig style regulator, not a flowmeter.
[12:49:05] <Gigs-> I'd like to keep the mig hooked up and add my tig, but I don't know if I really need a flowmeter or what
[13:20:36] <JT-Shop> your running argon on your mig???
[13:20:58] <Gigs-> it is an existing setup, but yeah I guess they are
[13:21:11] <JT-Shop> you can't guess
[13:21:19] <Gigs-> well my dad has always called it argon
[13:21:40] <Jymmm> argon, hydrogen, it's all the same
[13:21:43] <JT-Shop> CO-2 or CO2 mix is for mig and Argon is for tig
[13:22:03] <Gigs-> I'm pretty sure it's not CO2
[13:22:09] <Jymmm> nitrogen
[13:22:12] <Jymmm> NO2
[13:22:16] <jdh> migs run on Jet A-1
[13:22:20] <JT-Shop> then it is mixed
[13:22:21] <Gigs-> hehe N2O would be fun
[13:22:36] <Jymmm> jdh: kerosen
[13:22:38] <Jymmm> e
[13:22:43] <Gigs-> I would guess it's not pure argon
[13:22:53] <Gigs-> I can check and make sure
[13:23:16] <Gigs-> I think I'm going to just use the other tank that one of my dad's friends abandoned there, I know he was using it with tig
[13:23:22] <JT-Shop> its usually a mix of argon and co2
[13:23:36] <Gigs-> that will save putting a Y connector on
[13:24:06] <JT-Shop> if it is out of date you won't be able to get it filled without a hydro test
[13:25:44] <Jymmm> tank exchange FTW!!!
[13:25:52] <Gigs-> yeah I don't think any place around here fills inert
[13:26:00] <Gigs-> they are all exchanges
[13:26:29] <Gigs-> the other tank has gas in it anyway
[13:26:41] <Gigs-> I don't remember exactly but I think it was around 2300
[13:27:01] <Jymmm> PSI or Dollars???
[13:27:05] <Gigs-> psi
[13:27:13] <Jymmm> oh ok, just checking =)
[13:27:24] <Gigs-> it is a large tank
[13:27:38] <Jymmm> If it was $2300, I have a bridge for sale, cheap!
[13:27:41] <Gigs-> I sent him an SMS about buying it and he kind of gave me a vague answer like he isn't sure what tank it is
[13:27:49] <Gigs-> I don't know if he even owns it or is renting it
[13:27:56] <jdh> we use He for tig
[13:28:18] <Jymmm> jdh: dont you use He in your scuba stuff too?
[13:28:23] <JT-Shop> I've never seen any tanks above the small tanks that are user owned
[13:28:38] <JT-Shop> the big tanks are at the best a life time lease
[13:28:46] <jdh> yeah, painful paying for it now.
[13:28:54] <Gigs-> well if it's an exchange tank you only sort of own it anyway
[13:29:08] <Gigs-> you just don't pay rent
[13:29:11] <jdh> you can usually rotate customer-owned-cylinders in alos
[13:29:42] <Gigs-> yeah like grill propane work
[13:30:22] <JT-Shop> usually you can't exchange tanks from one dealer to another
[13:30:33] <Jymmm> Heh, I refill my propane tanks. Unless the tank is expired, then exchange it at Lowes super cheap.
[13:30:41] <JT-Shop> nothing like propane tanks
[13:31:15] <Gigs-> if both exchanges accepts customer owned tanks, then why not?
[13:31:23] <Jymmm> JT-Shop: The place I goto will exchange any tank, but I have a 40cf one.
[13:31:35] <JT-Shop> propane?
[13:31:39] <Jymmm> Nitrogen
[13:32:17] <Gigs-> Jymmm: refilling propane does make more sense as long as you get a competent operator
[13:32:24] <JT-Shop> around here who ever you rent the tank from is where you have to take it to be filled
[13:32:40] <Jymmm> JT-Shop: I own my tank.
[13:32:54] <jdh> other gas companies won't let you rotate in a bottle with a different ID on the neck ring
[13:33:02] <Jymmm> JT-Shop: So I just exchange it with whoever is cheapest.
[13:33:23] <Gigs-> Jymmm: my dad tried to get his 100 pound propane tank filled in the summer... I think it tared out at like 40 pounds when done
[13:33:24] <Jymmm> jdh: Yeah, there is no ID on mine.
[13:33:51] <Jymmm> Gigs-: I just have 4x 20lb tanks
[13:33:56] <jdh> I pay $15/year/bottle for tank lease and don't worry about it
[13:34:17] <Jymmm> I pay $17 including tax for exchange
[13:34:43] <Gigs-> sounds like a price fixing racket in you guy's area
[13:34:52] <Gigs-> if you have companies that won't deal with customer owned tanks
[13:34:56] <Jymmm> Gigs-: why's that?
[13:35:01] <Jymmm> oh
[13:35:05] <jdh> mine are 300ft^3 cylinders
[13:35:25] <Gigs-> because a lot of people probably get a tank and then never hardly use it, so the rent makes them the most money long term
[13:35:25] <jdh> I could do customer owned, but I have 8 bottles and I don't want to own them.
[13:35:29] <Jymmm> jdh: Yeah, big tanks are different like JT-Shop said
[13:35:56] <Jymmm> Anything 80cf or less they dont sweat
[13:36:08] <Loetmichel> *hmmm* i think i shoud get a vaccum for the company CNC mill. just wahsed a machine full of socks and knickers... and at hanging it on the line i see silver "snow" spilling out...
[13:36:17] <Loetmichel> (aluminium swarf)
[13:36:18] <Gigs-> how many cf is the 6 foot tall one?
[13:36:33] <jdh> Gigs: depends on the gas, 280-330ft usually
[13:36:41] <Gigs-> Loetmichel: I wear converse and I hate getting chips in my shoe
[13:36:49] <JT-Shop> and the tank, some have thicker walls than others
[13:37:32] <Jymmm> New meaning to "bottle rocket" =)
[13:37:34] <Gigs-> well the tank in question is that big, so he probably is renting it
[13:37:36] <JT-Shop> I recovered a couple of leased tanks for my supplier and the o2 tank weighed a ton
[13:37:55] <Gigs-> I'll just use all his argon
[13:38:02] <JT-Shop> LOL
[13:38:02] <jdh> my o2 bottles are physicaly identical to my He ones.
[13:38:04] <Gigs-> and when it runs out buy a little tank
[13:38:15] <jdh> except for the paint
[13:38:16] <Jymmm> If the tank has a screw on cap, it's usually not customer owned.
[13:38:26] <Loetmichel> arent o2 BIG tanks made of bundles of smaller "bottles"?
[13:38:33] <Gigs-> I've seen little tanks with screw on caps
[13:38:43] <Jymmm> Gigs-: Ah, I never have.
[13:39:13] <jdh> Loetmichel: maybe for big ones, but these are just normal DOT3A cylinders
[13:39:50] <Gigs-> heh did you know you could buy full tanks online?
http://store.cyberweld.com/shielgascyl8.html?utm_medium=shoppingengine&utm_source=shopzilla#pdItemDataTabs
[13:39:52] <jdh> some dive shops I use in florida get liquid oxygen
[13:40:06] <Gigs-> I wonder if the shipping is another $200 though heh
[13:40:28] <jdh> Free standard ground shipping within contiguous U.S.
[13:40:40] <Loetmichel> jdh: JT-Shop said his tank "weighted a ton" so i had a bundle of smaller tanks in mind
[13:40:46] <Gigs-> hmm well they might make you pay hazmat fee though
[13:41:04] <Jymmm> Gigs-: inert gases
[13:41:12] <Gigs-> compressed gasses
[13:41:16] <Jymmm> true
[13:41:21] <Loetmichel> because at 200++ bar of pressure a big tank would simply burst regardless of wall thickness
[13:41:24] <Jymmm> they just say signature required
[13:41:34] <JT-Shop> Loetmichel: they told me those tanks had thicker walls than the new onew
[13:41:36] <JT-Shop> s
[13:41:50] <Jymmm> Loetmichel: much like your knickers if you keep filling them with swarf!
[13:41:58] <Loetmichel> hrhr
[13:42:08] <Gigs-> Jymmm: hmm well I added it to cart and I don't see a fee on checkout page, not bad
[13:42:10] <jdh> Loetmichel: nah, I fill big tanks to 300+bar
[13:42:59] <Loetmichel> Jymmm: like i said: have to get some sort of swarf disposal... milling sheet aluminium with 2mm 2flute and 24krpm tends to get you ready made "flitter" for metallic paints ;-)
[13:43:05] <Loetmichel> thet gets everywhere
[13:43:09] <jdh> I fill one of my rental helium tanks to 3200psi with air. Hope they don't mind.
[13:44:40] <Jymmm> Loetmichel: justify it all you want, still sounds like some kind of kinky fetish to me. Two Mills, One Guy
[13:45:48] <Loetmichel> Jymmm: mill...
[13:45:52] <Loetmichel> dont think so ...
[13:46:02] <Jymmm> whaatever
[13:46:18] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14148
[13:46:25] <Loetmichel> more like a glorified router
[13:46:50] <Loetmichel> and thats the problem: no housing but very small swarf
[13:47:09] <Jymmm> First there's JT-Shop and his custom sex toys, now Loetmichel with a crotch full of swarf. What's next?
[13:47:13] <Loetmichel> jdh: depends on your definition of "big" ;-)
[13:47:47] <jdh> 'normal' size storage bottles
[13:48:10] <jdh> 8500l or so
[13:48:50] <Loetmichel> jdh: 8500liters UNPRESSURIZED?
[13:49:01] <jdh> heh, no.
[13:49:06] <jdh> that woudl be *big*
[13:49:06] <Loetmichel> or 8500 liters volume inside the "bottle" ?
[13:49:11] <jdh> 8500 free liters
[13:49:25] <Loetmichel> ah, yes, thats what i meant ;-)
[13:49:38] <Loetmichel> so about 10 liters volume of the "bottle"
[13:50:03] <jdh> more like 40
[13:50:54] <jdh> we don't use sane measurements here though.
[13:51:52] <jdh> 40l cylinder, 200 bar... makes way too much sense. Instead, we use number of free cubic feet at rated pressure.
[13:52:32] <Loetmichel> in germany hte containers are calles "gas bottles" and are measured by liters volume or (in case of porpane) by kg
[13:52:45] <Loetmichel> not by the free liters
[13:53:43] <jdh> yeah, wish we did.
[13:56:12] <jdh> mine come 2200-2500 psi. Used to bother me but I bought a 300 bar gas booster so I don't really care any more.
[13:57:10] <Gigs-> http://store.cyberweld.com/prcy5ca.html
[13:57:17] <Gigs-> that's cute, I should mount that on the back of my lawn mower
[13:57:31] <Gigs-> I'm sick of the modern gasoline
[13:57:32] * Loetmichel hat some diving "lessons" a t a frends in sardinia.
[13:57:53] <Loetmichel> friend of mine has a salvage company there which salvages sunken yacts and stuff
[13:58:13] <Loetmichel> he charges the air tanks to ~280 bar...
[13:58:28] <Loetmichel> one time the relief walve had hung...
[13:58:39] <Jymmm> Gigs-: Lil pricy though
[13:59:02] <Gigs-> yeah it is
[13:59:15] <Loetmichel> result: one third of an air tank (bottom) on display like a banana and a totally destroyed copressor station
[13:59:15] <Gigs-> a 20 pound tank on the back of the lawn mower would give it more traction anyway
[13:59:25] <Jymmm> Gigs-: I just refill the disposable 1# tanks =)
[13:59:42] <Loetmichel> and the peak indicator an the manometer stodd at 420 bar
[13:59:45] <Gigs-> I tried that once, it's annoying without a pump[
[14:00:01] <Jymmm> Gigs-: not at all, pretty easy
[14:00:33] <Gigs-> I couldn't get it to fill at a reasonable rate, even with a warm bath on the big tank and ice on the little one
[14:00:59] <Gigs-> how did you do it? Could you get a siphon started somehow?
[14:02:22] <Jymmm> Gigs-: Toss the 1# tanks in the freezer over night (just to be extra sure), Toss the 20# tank in the sun. I wieght the 1# tanks before and after to get an idea. Then fill is done in about 4 minutes.
[14:02:41] <Gigs-> hmm ok will have to try again sometime
[14:02:57] <Jymmm> Gigs-: Can't fill it on a cold day.
[14:03:31] <Jymmm> Gigs-: BE SURE TO CHECK THE TANKS FOR LEAKS!!!!
[14:04:01] <Jymmm> those shrader valves are notorious for not reseating properly.
[14:04:05] <Gigs-> yeah they suck
[14:04:24] <Gigs-> the same thing can happen with a non-refilled tank that you left a torch on for a long time anyway
[14:04:44] <Jymmm> But it sure in the hell beats $4-$5/each.
[14:05:00] <Gigs-> if you get them on the off season you can get them for $3 sometimes
[14:05:19] <Gigs-> really I don't know how they manage to sell them that cheap
[14:05:30] <Jymmm> Gigs-: I have enough now that I shouldn't need to buy anymore.
[14:05:32] <Gigs-> I guess 90% of the cost is the tank
[14:05:50] <Gigs-> they make a decent bowl to pour molten metal into
[14:06:17] <Gigs-> non-tip base and thick enough not to warp, and the bottom is rounded so the metal usually doesn't stick too bad
[14:06:24] <Jymmm> Gigs-: lol, no idea. They are just for my heater if the gf needs to use it.
[14:06:40] <Gigs-> well next time you have one with a leaky valve, cut the last 3 inches off
[14:06:48] <Gigs-> it's a pretty useful heavy duty bowl
[14:06:53] <Jymmm> cool
[14:07:08] <Jymmm> I have one on the torch marked "leaks" right now.
[14:07:54] <Gigs-> you can unscrew the valve with a tire tool to get it aired out before cutting
[14:08:29] <Jymmm> Yeah, angle grinder + propane tank dont sound like a good combination =)
[14:08:35] <Gigs-> speaking of air, you can also convert it into a tiny air tank
[14:08:43] <Gigs-> it's not very useful as that though
[14:09:08] <Gigs-> I sometimes use one that I put air fittings on to carry a few bursts of compressed air to my computer though
[14:09:10] <Jymmm> I use the nitrogen tank for that.
[14:09:29] <Jymmm> and no moisture either.
[14:09:56] <GammaX-Shop> anyone have a spare 3jaw chuck they would like to trade? :D
[14:10:02] <jdh> sure
[14:10:08] <jdh> I'll trade it for a VMC
[14:10:19] <jdh> or legal firearms.
[14:10:29] <Jymmm> or illegal firearms
[14:10:36] <jdh> ok, whatever.
[14:10:45] <GammaX-Shop> jdh: how big of a mill do you currently have?
[14:10:54] <jdh> small!
[14:10:57] <GammaX-Shop> damn...
[14:11:10] <jdh> and a small 3 jaw chuck
[14:11:13] <GammaX-Shop> im trying to get rid of these 1" carbide end mills I have.
[14:11:33] <GammaX-Shop> worth like 100-150 each
[14:11:41] <jdh> ebay!
[14:11:51] <GammaX-Shop> yeah I know...
[14:11:51] <JT-Shop> lol
[14:12:02] <GammaX-Shop> JT-Shop: in the mod for a swap? :)
[14:12:09] <GammaX-Shop> mood*
[14:12:47] <JT-Shop> no, you have too much sentimental value for them
[14:13:17] <GammaX-Shop> no i dont lol
[14:13:20] <jdh> I'll trade you a 4 jaw chuck for them, and throw in a lathe.
[14:13:26] <GammaX-Shop> hahaha
[14:13:30] <GammaX-Shop> where you live at?
[14:13:52] <jdh> NC, but I can ship this one.
[14:13:57] <jdh> http://tinyurl.com/mjhdsm7
[14:14:09] <GammaX-Shop> lol!
[14:14:13] <GammaX-Shop> shes a baby!
[14:14:50] <GammaX-Shop> Too small brother lol THanks though?
[14:15:03] <GammaX-Shop> jthornton: when you headin to NC?
[14:15:12] <GammaX-Shop> JT-Shop: meant for you ^^^
[14:16:03] <JT-Shop> you said they are worth 100-150 each that is way too much for me, I'd rather purchace new so I know what I'm getting
[14:20:34] <GammaX-Shop> they are like new... gar I think 630m? 2 of them are 1x6x3 and I think other one is 1x6x1
[14:20:49] <GammaX-Shop> I also believe these are 4 flute ones.
[14:21:33] <GammaX-Shop> http://www.ebay.com/itm/Garr-Tool-End-Mill-1-x-6-x-3-630-M-/151033396256?pt=LH_DefaultDomain_0&hash=item232a4abc20
[14:22:04] <GammaX-Shop> I dont think theyve ever been used to be honest...
[14:25:48] <JT-Shop> never heard of Garr, and sharp corner end mills don't last long
[14:26:47] <JT-Shop> this is what I use
http://www.lakeshorecarbide.com/1dia4fluteendmillaltincoated.aspx
[14:29:24] <JT-Shop> anything over 5/8" I use insert tooling, $20 worth of inserts and I have a new end mill
[14:29:54] <andypugh> I sometimes wonder why they bother with so much flute.
[14:31:01] <toastydeath> manual machines that have to take full depth pass to blend properly
[14:31:43] <JT-Shop> and sometimes you need center cutting
[14:32:21] <JT-Shop> hmmm duct tape worked well
[14:42:52] <JT-Shop> dang laying the belts side by side explains a lot
[15:00:47] <willburrrr2003> Good afternoon all :)
[15:03:09] <willburrrr2003> I took the time to print the entire current set of manuals for Linuxcnc, and have been doing lots of reading through them getting ready to fire off my machine for first time in almost a year and a half
[15:09:58] <JT-Shop> wow, how many pages?
[15:11:32] <Jymmm> JT-Shop: You should know, you wrote the damn things!
[15:12:15] <JT-Shop> LOL, I just tossed them up in the air and put them back together
[15:15:04] <willburrrr2003> just shy of 500 I think, as I did 2 of the larger manuals 2 pages per sheet
[15:15:33] <willburrrr2003> I find having the hard copy for me is easier to reference and use while I am working
[15:15:51] <Jymmm> willburrrr2003: Just get yourself a 7" tablet
[15:16:04] <JT-Shop> willburrrr2003: want more information?
[15:16:06] <Jymmm> willburrrr2003: When your eyes go bad, you can increase the font size =)
[15:22:19] <willburrrr2003> JT-shop, what other information do you have ?
[15:22:39] <alex_joni> wiki, forum, irc logs
[15:22:54] <JT-Shop> some stuff I put together
http://gnipsel.com/linuxcnc/index.html
[15:23:54] <willburrrr2003> OOOOOH JT-Shop, that looks like lots of great stuff!! Thanks
[15:24:34] <willburrrr2003> BTW, I found 3 references in the updated docs that refer to EMC and EMC2, JT would you be the one to mention this to?
[15:26:25] <JT-Shop> yep, if you have links that would be great
[15:31:51] <willburrrr2003> http://linuxcnc.org/docs/LinuxCNC_Getting_Started.pdf is the pdf with the 3 instances. The references are in figures 5.1, 5.2, and 5.3 , I am guessing that is why they got missed, as searching the docs wouldn't find them in the pics on in the text instead
[15:32:57] <willburrrr2003> the same instances are in the HTML docs as well at linuxcnc.org/docs/html/stepconf.html figures 1, 2, and 3
[15:35:32] <JT-Shop> thanks, I'll just have to make some new screen shots when I get back from my road trip
[15:38:47] <willburrrr2003> JT , no problem... I will let you know if I find any more
[15:40:26] <JT-Shop> ok, thanks
[15:47:55] <Tom_itx> Garr are ok
[15:50:03] <Tom_itx> much more than an inch you may as well go to insert cutters though
[15:53:44] <JT-Shop> at least you have heard of them lol
[15:54:15] <Tom_itx> probably not the most common brand
[15:54:19] <Tom_itx> but yes
[15:54:56] <Tom_itx> just tried doing surgery on my thumb with a box knife
[15:55:40] <JT-Shop> ouch
[15:57:25] <Tom_itx> LOC would be from the shank to the cutting tip right?
[15:57:28] <Tom_itx> http://www.lakeshorecarbide.com/variableflutesingleprofilecoatedthreadmill300cutdia38shank.aspx
[15:57:37] <Tom_itx> the 'recessed' area
[15:58:20] <PetefromTn> Afternoon folks....
[15:58:42] <JT-Shop> the cutting edge may not go all the way up to the shank but will be close
[15:59:23] <Tom_itx> i should probably get the longer of the two
[15:59:36] <Tom_itx> 1" opposed to 3/4
[16:00:26] <Tom_itx> do you know if you can profile pipe threads with those?
[16:01:18] <JT-Shop> I would assume a snigle cutter like that could
[16:01:33] <Tom_itx> same here but i haven't used one
[16:02:35] <PetefromTn> Single point threadmills?
[16:04:52] <DJ9DJ> gn8
[16:06:02] * Tom_itx bets JT-Shop has LS carbide on speed dial
[16:06:32] <JT-Shop> I just order online but not often
[16:06:43] <andypugh> This guy is thread-milling 2mm threads in titanium. (1.6mm hole). I bet that's scary when the cutter costs £160.
http://www.f1-2000.co.uk/index.php?f=conrods
[16:06:49] <Tom_itx> do you have any place there that does sharpening?
[16:06:59] <PetefromTn> Never bought from them but I hear a lot of good things. I believe maritool also now has single point threadmills.
[16:07:27] <JT-Shop> I get all my tool holders from Maritool
[16:08:27] <PetefromTn> I've bought lots of cutters from him and now intend to try to buy future toolholders cat40 from him as well. Good quality so far.
[16:09:48] <Tom_itx> andypugh, i wonder if they twisted any when he cut the profiles
[16:10:09] <Tom_itx> not sure about predrilling the holes
[16:10:37] <andypugh> Tom_itx: He is a total perfectionist. They wouldn't have dared :-)
[16:11:26] <Tom_itx> he put some sort of bushing in when he bolted them down to profile
[16:11:37] <andypugh> I don't think he has touched the engine for a while, he has caught LinuxCNC retrofit-itis.
[16:11:48] <Tom_itx> uh oh
[16:12:05] <andypugh> Doing a very nice retrofit on a Hardinge HNC
[16:12:26] <Tom_itx> judging from his work there, i bet
[16:12:38] <PetefromTn> That looks like some nice work there. Is that a miniature Ferrari engine or something? What kinda mill is that?
[16:13:08] <andypugh> Actually, Hardinge HXL now I look.
[16:13:17] <andypugh> The mill is a Deckel FP2.
[16:13:20] <andypugh> Lovely machines
[16:13:53] <andypugh> http://www.f1-2000.co.uk/index.php?f=deckel_fp2a
[16:16:30] <Tom_itx> i wonder if he radius'd all the conrod edges or if that was the result of a vibra tumbler
[16:17:11] <PetefromTn> I've heard those deckels are sweet but kind of a nightmare to retrofit.
[16:17:32] <sharpen047> hey everyone
[16:18:56] <andypugh> This one was CNC from the factory, and is still running the original control. They close the loop with glass scales, so I can see that a Mach3 retrofit would be a challenge :-)
[16:19:32] <toastydeath> I saw a four axis jig grinder going cheap once
[16:20:02] <toastydeath> i imagine that control would be a pain in the balls to replace as well
[16:21:35] <sharpen047> anyone make plexi signs here?
[16:21:44] <willburrrr2003> awhile back someone was working on a graphical HAL editor, but I can't remember who....do you guys know who this might be?
[16:23:24] <PetefromTn> Hello again...
[16:24:14] <JT-Shop> http://www.youtube.com/watch?v=MMp5YBW-nJ4
[16:24:15] <Tecan> (MMp5YBW-nJ4) "The Kingston Trio - Where have all the flowers gone?" by "GangstaParadise107" is "Music" - Length: 0:04:06
[16:29:05] <PetefromTn> Well I milled my first paying job on the Cincinnati today...
[16:29:25] <PetefromTn> Nothing earth shattering LOL
[16:29:55] <JT-Shop> even if you made a dollar it will be a good one
[16:30:04] <PetefromTn> Just had to mill three slots in an oval shape on both sides of six pieces of rectangular steel tube.
[16:30:23] <PetefromTn> Yeah buddy..
[16:31:03] <PetefromTn> I programmed the part as just the three slots and cut each tube one side at a time.
[16:31:32] <PetefromTn> Machine did a nice job and the cuts look very good. Especially for hrs
[16:32:06] <lomach> Thats great Pete. No stopping you now
[16:32:15] <PetefromTn> Hey lee!!
[16:32:31] <toastydeath> PetefromTn, pic of machine?
[16:32:46] <PetefromTn> Yeah now I just need to find some more paying work for it..
[16:32:49] <toastydeath> I've always liked cinci machines, they've been around so long as a mfg that they made some real weird shit
[16:34:07] <PetefromTn> Yeah it is a decent little mill. Has been kind of challenging to retrofit since I have never done a commercial machine but so far so good.
[16:34:32] <lomach> Im sure more work will come soon.
[16:36:41] <PetefromTn> Sure hope so. Still need to design and machine an encoder mount and try to get spindle feedback working.
[16:37:25] <andypugh> willburrrr2003: Search the LinuxCNC for "crapahalic" "Eagle to HAL" and "graphviz"
[16:37:44] <lomach> Ive tapped about 400 off 1/8bsp holes in the last two days so all good with mine so far
[16:37:55] <willburrrr2003> thanks Andy, doing that right now :)
[16:38:41] <PetefromTn> Wow 400 holes sounds good LOL...can't wait for that capability
[16:40:19] <JT-Shop> willburrrr2003: I've done some graphviz on my tutorial pages
[16:48:41] <PetefromTn> I was having some confusing setup head scratching tho...
[16:49:52] <lomach> It what sense pete
[16:50:06] <lomach> in what sense i meant to say
[16:50:29] <PetefromTn> Well for instance I have setup my vise on G54
[16:51:13] <PetefromTn> Then I was using the same tools I used to machine my cat40 tool fixture the other day.
[16:51:31] <PetefromTn> Well I would insert the program
[16:52:42] <PetefromTn> And then put the first tool number 1 in the spindle and hit cycle start. The too should have already been in there and I touched off the work offset earlier for this part.
[16:53:15] <PetefromTn> Then when I hit CS the machine goes up to toolchange height...
[16:53:44] <PetefromTn> Which is how I programmed it in my post processor(no toolchanger yet)
[16:54:31] <willburrrr2003> JT-Shop, under whuch topic on your pages I am not seeing it there?
[16:54:31] <PetefromTn> The head goes up and stops at z zero machine coordinate
[16:54:32] <JT-Shop> http://gnipsel.com/linuxcnc/hal/or2.html
[16:54:34] <PetefromTn> Then it says the joint 2 will exceed minimum limits..
[16:55:13] <PetefromTn> I have to then bring the head back down and touch off even tho I already did
[16:55:14] <lomach> Pete do you have g49 in your post at the start. Think i had the same problem
[16:55:33] <lomach> It cancels tool length offset
[16:55:37] <JT-Shop> PetefromTn: are you using Tn M6 G43 for your tool change?
[16:56:09] <PetefromTn> Then it seems to have the right offset and the dtg looks right so I proceed with caution until I know it is doing what I expected.
[16:56:54] <PetefromTn> Lomach gotta look at it...not sure.
[16:57:26] <PetefromTn> Jt shop....in the program?
[16:57:33] <lomach> I will send you my standard code layout tomorrow when im at work.
[16:57:34] <JT-Shop> aye
[16:58:03] <PetefromTn> Standby ...
[16:58:31] <JT-Shop> PetefromTn:
http://gnipsel.com/linuxcnc/g-code/gen05.html
[16:59:15] <PetefromTn> Gonna switch to my laptop cannot do this from smartphone...
[16:59:23] <PetefromTn> Be right back..
[17:00:30] <PetefromTn> hello again.
[17:00:44] <PetefromTn> JT-Shop Can ya repost that link please?
[17:00:54] <JT-Shop> http://gnipsel.com/linuxcnc/g-code/gen05.html
[17:01:05] <PetefromTn> thanks..
[17:01:32] * JT-Shop goes to sleep a bit... 3AM departure time is real early
[17:01:41] <Tom_itx> drive safe
[17:01:52] <PetefromTn> gnite..
[17:02:30] <PetefromTn> okay no g49 in my code...
[17:03:34] <PetefromTn> N0081 G53 G0 Z0
[17:03:43] <willburrrr2003> c-ya JT
[17:03:56] <PetefromTn> N0091 M6 T1 (Mill/router, 0.375 in diameter)
[17:04:00] <PetefromTn> N0101 G43 H1
[17:04:16] <PetefromTn> thats my TLO callout from sheetcam.
[17:04:17] <lomach> From memory I had to put g49 on the first line of any program. Just once though
[17:05:25] <PetefromTn> So you cancel any previous TLO and THEN the code calls the first tool?
[17:07:14] <lomach> Yes thats right. I dont have any programs with me but will email you a proven one tomorrow
[17:07:23] <PetefromTn> okay thanks..
[17:08:15] <PetefromTn> Yeah it is kinda frustrating because I feel like I should just be able to Home the machine, load a program, and select my G54 offset and hit go without having to pick up tools twice.
[17:08:19] <lomach> Pete when you go to machine zero do you use g0 g53 z0 or something else
[17:08:31] <PetefromTn> Yeah G53 Go Zo
[17:08:57] <PetefromTn> just posted the lines of code a minute ago.
[17:09:05] <lomach> Im confident adding the g49 will sort it out
[17:10:08] <PetefromTn> Whats the issue with it, seems like If I do an MDI and select my first tool, touch off with it and then run the program it should run up to toolchange position and then down and start the programmed cuts.
[17:10:23] <PetefromTn> The g49 not sure what it would do really.
[17:11:18] <lomach> To be honest I cant answer that but i do remember having the same problem.
[17:11:31] <PetefromTn> okay I'll take your word for it.
[17:11:48] <PetefromTn> Any other words of wisdom for the machine you care to share LOL?
[17:13:59] <lomach> Nothing off the top of my head. Its been a long learning curve though
[17:14:10] <PetefromTn> understand that LOL
[17:14:49] <PetefromTn> RIght now I am just pleased that the machine made a program run a dozen times without any issues. That was nice..
[17:15:13] <PetefromTn> I am gonna design some more parts and make some test runs with the machine and see how she does on something more complex.
[17:16:58] <lomach> Its so nice seeing all your hard work start to pay off.
[17:20:07] <PetefromTn> yeah you can say that again...
[18:11:58] <andypugh> PetefromTn: I am a bit puzzled, because I definitely don't need to re-touch-off my machine. If it is homed, it is homed.
[18:12:34] <PetefromTn> andypugh Agreed I am not homing the machine again, just picking up the tool..
[18:14:09] <andypugh> I put the G43 on the same line as the T1 M6, and I don't bother with the H.
[18:14:29] <andypugh> (by default it uses the offsets for T)
[18:14:52] <PetefromTn> andypugh Yeah that is just the way the EMC post in Sheetcam does it...
[18:15:26] <andypugh> Ah, but, you do need to touch-off the "reference" tool into the G54, then the other tools into the tool table.
[18:16:12] <Tom_itx> touch off to workpiecd
[18:16:13] <Tom_itx> e
[18:16:25] <Tom_itx> make sure you select that
[18:16:27] <andypugh> So, one tool is defined as zero-length (it makes a lot of sense for this to be a probe) and then the tool-table entries are the offsets from that reference.
[18:16:40] <PetefromTn> LIke I said my reference tool is currently the first tool and it is already in the table.
[18:17:27] <PetefromTn> Tom_itx Ya know I am not sure if I did that...
[18:17:38] <Tom_itx> it matters
[18:17:57] <PetefromTn> Thats in the drop down menu not just the touch off button in the manual tab right.?
[18:18:26] <PetefromTn> I mean the top menu up there with file etc..
[18:18:32] <andypugh> I am talking about in the Axis interface, where the choices are to touch-off G54 (etc) or T. (in practice, behind the scenes, this is the difference between a G10 L10 and a G10 L20.
[18:19:02] <Tom_itx> PetefromTn, yes
[18:19:30] <andypugh> But if the tool is the reference tool, then just the one touch-off should be needed (but check that the tool has zero length in the tool table).
[18:20:00] <PetefromTn> When I set the G54 offsets for the vise I was in manual mode and hit touch off and the popup gave me the option to set a numeric offset and said Z axis and G54 so I thought I was okay.
[18:20:37] <Tom_itx> i got screwed up once when i didn't have that option set
[18:21:44] <PetefromTn> andypugh I thought I could just use the actual tool to set the work coordinate and have it zero for that and use the TLO for the same tool no?
[18:21:56] <PetefromTn> Either way it worked properly once I did it the second time.
[18:22:34] <PetefromTn> Not really sure why it does that but like I said maybe I need to select touch off to workpiece like Tom said.
[18:23:09] <PetefromTn> Same thing happened when I made that cat40 fixture too.
[18:23:27] <PetefromTn> I am gonna try to insert that G49 into my post and see if that fixes it.
[18:26:07] <Tom_itx> i do T1 M6 G43 and move to where i want the G54 x y z zero set with "tool touchoff to workpiece" selected and set the fixture offsets
[18:26:13] <andypugh> There shouldn't be any need for G49. I don't even know what it does, so clearly have never needed it.
[18:26:20] <Tom_itx> and set the rest of the tools to that z height
[18:26:32] <Tom_itx> or touchoff to the same z point
[18:26:41] <Tom_itx> heh
[18:27:02] <andypugh> This is my process (largelky borrowed from JT).
[18:27:26] <PetefromTn> understand that my tool table is NOT what it will be. These first cuts are more tests than anything.
[18:27:43] <PetefromTn> I intend to get a holder for my edgefinder and make that my tool 1 touch off tool.
[18:27:50] <Tom_itx> G49 - cancel tool length compensation
[18:27:58] <Tom_itx> you want that on
[18:28:13] <Tom_itx> with G43
[18:28:16] <andypugh> Load the reference tool.Jog down to near the top of the work. Slowly jog the Z upwards until a 6mm dowel slips under the tool. Hit touch-off, select G54, type in "6mm" as the axis position.
[18:28:46] <andypugh> If there are any other tools to be used, then repeat the process, but select "T" rather than "G54" in the touch-off dialog.
[18:28:56] <PetefromTn> Then I will set that tool on my table and make it zero, followed by every other tool the same way basically.
[18:29:34] <PetefromTn> andypugh Okay so do you do this for every part run I mean the tools...
[18:29:41] <Tom_itx> don't directly edit the tool table z offsets
[18:29:47] <andypugh> On my mill-in-progress I intend to use a probe and a setting gauge though.
[18:30:34] <PetefromTn> Tom_itx I would only do that if I ever get a fixture for my large granite surface plate and do offline measurement like I did with the Tormach Tooling on my Rf45.
[18:31:01] <andypugh> PetefromTn: You need to do the G54 touch-off any time that you change workpiece thickness.
[18:31:30] <andypugh> But after that you should only ever need to touch-off a tool when its length has changed.
[18:31:33] <PetefromTn> andypugh Yeah I know what I am asking is if you go thru all your tools in that program each time..
[18:31:48] <PetefromTn> yeah that is what I figured, I do that same thing.
[18:32:28] <PetefromTn> Incidentally I just measured a few of these parts I made for that customer.
[18:32:49] <PetefromTn> The holes were supposed to be 12mmx18.6mm oval slots.
[18:33:05] <andypugh> I only actually have repeatable tool-length on the lathe. But in theory that should never need to be touched off again once all the tools are in the table. In practice I keep hitting the wrong option in touch-off and messing the setup up.
[18:33:20] <PetefromTn> they are all within .01mm or so.. Amazing this machine is and I did not even tweak anything really yet.
[18:34:00] <andypugh> I am happy when my Chinese mill manages 1mm tolerance and only breaks a couple of toolbits.
[18:34:23] <andypugh> I have higher expectations from the Harrison.
[18:34:35] <PetefromTn> andypugh Yeah I know how you feel. My RF45 was not too bad but the Cincinatti is in another class altogether.
[18:35:25] <PetefromTn> It's just nice to know that when I program it I can expect some relativley precise results in the finished part.
[18:36:03] <PetefromTn> Still needs lots of tweaking and work but so far the programmed cuts are impressive and the finish is excellent even in this shitty hot rolled square tubing...
[18:37:30] <andypugh> It sounds more like a plasma-cutter job, but as long as it pays, who cares?
[18:38:21] <PetefromTn> actually he needed some smooth sides to the holes because they are basically an eccentric adjuster that slides on a cam head bolt...
[18:38:40] <PetefromTn> a CNC laser might have done a decent enough job probably...
[18:57:09] <sharpen047> andypugh: hey how ya doin
[18:57:49] <andypugh> I am about to head to sleep.
[18:58:04] <jthornton> me too in a bit
[18:58:11] <jthornton> want me to wake you at 3AM
[18:58:32] <andypugh> I should already be up by then.
[19:16:00] <jthornton> see you guys Thursday
[19:16:37] <jdh> have a nice drive
[19:17:18] <eric_unterhause1> or flight, as the case may be
[19:17:58] <jthornton> thanks, it is a drive
[19:21:01] <jdh> flight woudl be much better
[20:03:57] <sharpen047> what are zero helix end mills usually used to cut?
[20:08:57] <Tom_itx> dunno
[20:09:13] <Tom_itx> chamfer the end and you have a reamer though :)
[20:09:52] <Tom_itx> we used half round drill bits in brass
[20:10:01] <Tom_itx> no helix
[20:16:36] <sharpen047> hmm i have 1,2 and 3 flute cutters for plexiglass
[20:17:20] <sharpen047> all have a spiral
[20:23:08] <Valen> its used when you dont want things getting pulled up
[20:23:19] <Valen> timbers and things like that i believ
[20:23:19] <Valen> e
[21:46:12] <PetefromTn> Jeez this place seems dead lately.
[21:47:18] <jdh> so, pick it up
[21:47:53] <PetefromTn> kay, anybody making anything interesting on your CNC machines?
[21:48:40] <PetefromTn> I am sitting here trying to come up with something cool to make on mine so I can continue to get a feel for how it likes to be run.
[21:50:11] <PetefromTn> also gotta machine some hold down clamps for the CNC vise so I can take back my hold down kit parts.
[21:50:33] <Tom_itx> make a sacrificial plate for it
[21:50:39] <Tom_itx> with a grid of tapped holes
[21:51:07] <PetefromTn> Not a bad idea but I can't tap just yet still need the encoder on the spindle for that.
[21:51:29] <jdh> I thought you had an encoder
[21:51:35] <jdh> and a prox switch
[21:51:53] <PetefromTn> I do have one just have not gotten it installed yet as I need a custom mount for the top of the spindle motor.
[21:52:27] <PetefromTn> the machine has several prox switches on the spindle for different functions
[21:52:55] <PetefromTn> it has tool clamp and unclamp, 180 out sensor, and something else..
[21:53:06] <PetefromTn> there's like four of them there.
[21:53:41] <Tom_itx> that's why i'm looking at single profile thread mills
[21:54:09] <PetefromTn> That is what I want to get too, Nice to be able to do multiple threads with one tool.
[21:54:28] <Tom_itx> i've got no reverse on my spindle yet
[21:54:34] <Tom_itx> or index encoder
[21:54:56] <PetefromTn> I've got reverse so I could actually use a floating head right now.
[21:55:07] <PetefromTn> That is how I tapped with my Rf45 CNC
[21:55:51] <PetefromTn> Honestly I would love to fabricate a simpler spindle feedback setup that would not need the 180 out sensor and the associated circuitry.
[21:58:08] <PetefromTn> so nobody making anything cool?
[21:59:05] <jdh> not me.
[21:59:16] <PetefromTn> I'm sorry..
[21:59:34] <jdh> me too.
[21:59:42] <PetefromTn> are ya making ANYTHING?
[21:59:45] <jdh> work and crap get in the way
[22:00:10] <PetefromTn> for me crap gets in the way, I'd welcome the work LOL.
[22:00:11] <jdh> spent thursday-sunday going to TN for a wedding. Made a lot of gas stations happy
[22:00:24] <PetefromTn> Oh yeah where in TN?
[22:00:30] <jdh> Nashville
[22:00:34] <PetefromTn> Aah.
[22:03:15] <PetefromTn> You know you got it bad when you search google for CNC machining ideas LOL.
[22:13:42] <skunkworks> nothing you need for the fiero?
[22:13:58] <pcw_home> PetefromTn: it _should_ be possible to use the index mask facility thats built into the hardware But I dont know if its been tried, worst case you will have to upgrade to master after a patch has been made
[22:14:22] <pcw_home> thats the cleanest way (no external hardware)
[22:15:03] <cradek> I use encoder mask on my hnc
[22:15:28] <cradek> it has like 10 indexes per screw turn and a prox on the pulley selects just one
[22:15:30] <PetefromTn> LOL yeah my fiero, honestly it is not running that good yet. I bought it running crappy and fixed a bunch of stuff with it but have not gotten it sorted yet. I did used to make some engravings for the fiero folks for sale but my macines spindle is only good for 6k so I need to fab up some sorta higher speed spindle before I can go back to making them.
[22:15:41] <cradek> it has worked for years, nothing new about it
[22:15:52] <cradek> index mask I mean, of course
[22:16:42] <pcw_home> Well not sure if muxed index mask works
[22:16:43] <PetefromTn> pcw_home Yeah I have heard it has the feature but we spoke about it before and Connor had been under the impression it was something that could only be accomplished with a small board and some sorta chip.
[22:16:56] <cradek> ah
[22:17:08] <cradek> yeah this is the old 7i33/5i20 combo
[22:17:24] <PetefromTn> I've got the 5i25/7i77...
[22:17:45] <PetefromTn> It would sure be nice if it would work in software.
[22:17:58] <pcw_home> It may need a driver tweak, I dont think the MIM option has been tried
[22:18:21] <PetefromTn> I purchased the differential encoder over the single ended because I needed the line driver.
[22:18:27] <PetefromTn> What is muxed?
[22:18:31] <pcw_home> The demux hardware has been in the firmware for years
[22:19:34] <pcw_home> the 6 encoders on the 7I77 are multiplexed (they would need 18 wires out of he 17 available otherwise)
[22:20:01] <pcw_home> s/ he/the/
[22:21:31] <PetefromTn> I am sorry but I just don't understand that. Remember I am not Connor the guru here LOL.
[22:22:15] <pcw_home> so the firmware sends the even encoder signals(0,2,4) alternately with the odd encoder signals (1,3,5)
[22:22:17] <pcw_home> on the same 9 wires
[22:23:23] <PetefromTn> this is the differential function then?
[22:23:54] <Connor> Someone say may name?
[22:24:15] <pcw_home> No, this is how the signals get crammed onto the 17 wires available on the DB25 interface
[22:24:34] <PetefromTn> oh okay.
[22:24:49] <PetefromTn> thats the mesa magic..
[22:25:04] <PetefromTn> Connor Yeah I guess I did LOL.
[22:25:23] <pcw_home> well multiplexing dates from telegraph days
[22:25:42] <PetefromTn> and modest too...
[22:25:54] <PetefromTn> so what is muxed?
[22:26:23] <Connor> PetefromTn: Taking multiple inputs and reducing them to down to a smaller amount.
[22:26:49] <PetefromTn> so basically that is what he was talking about which went over my head basically.
[22:26:52] <Connor> pcw_home: I was going to use a opto-coupler to mux the index + 180 out sensor.
[22:27:15] <Connor> pcw_home: I think we talked about how to do it a while back.
[22:28:22] <Connor> cradek: I have him running on 2.6.x code base.. if that's what you meant by upgrading him to master.
[22:29:28] <pcw_home> I mentioned to PetefromTn that it might be worth trying the built in hardware
[22:29:30] <pcw_home> though it may need a driver tweak. This has the advantage that no external hardware is needed
[22:29:32] <pcw_home> (as long as a TTL or differential mask signal is available)
[22:30:07] <Connor> It's a 24v proximity sensor.
[22:30:21] <PetefromTn> I think it is anyways..
[22:30:33] <PetefromTn> Have not checked it so far. Probably is tho...
[22:30:41] <Connor> PetefromTn: It is.. Lee confirmed it for me. and he's told me what wires are what.
[22:30:58] <pcw_home> Oh that makes it interesting (and so probably requires external hardware anyway)
[22:31:14] <PetefromTn> REALLY!! excellent. He helped me with something else earlier today.
[22:32:42] <PetefromTn> Connor Milled some steel today! Machine cut great man.
[22:32:51] <PetefromTn> in HRS no less.
[22:32:52] <Connor> Great!
[22:32:59] <Connor> HRS ?
[22:33:07] <ssi> he's right though, Mach3 is in a different class
[22:33:09] <PetefromTn> Yeah Hot rolled steel tubing
[22:33:12] <ssi> whoa
[22:33:32] <ssi> sry that was in my up arrow history from a week ago :P
[22:33:33] <PetefromTn> ssi hey man whazzup.
[22:33:40] <ssi> just got home from san fran
[22:33:50] <ssi> long day of traveling
[22:33:53] <PetefromTn> was wondering what happened to ya.
[22:33:57] <pcw_home> so the prox (on spindle) generates a ~180 degree mask?
[22:34:01] <ssi> yea I had to get out for a couple days :)
[22:34:24] <PetefromTn> pcw_home Yeah there is a half moon protrusion on the spindle body that the sensor picks up.
[22:34:41] <PetefromTn> I was just in San Fran a couple months ago.
[22:34:52] <PetefromTn> Love the fishermans wharf.
[22:35:31] <ssi> I didn't go into the city... spent most of my time in the valley
[22:35:39] <ssi> went up to muir woods and stinson beach yesterday
[22:35:52] <eric_unterhause1> sounds nice
[22:36:06] <PetefromTn> My wife and I used to ride my sportbike down the PCH and stay in Stinson Beach. Cool place.
[22:36:16] <eric_unterhause1> although we have some really nice woods out behind my house
[22:36:46] <Connor> ssi: Got the pulleys Friday. Will coordinate with pete for getting them bored out and turned correctly.
[22:36:52] <ssi> Connor: awesome, thanks :DH
[22:37:04] <ssi> I got my servo power supply and mesa gear in the mail while I was gone
[22:37:09] <PetefromTn> What does DH mean?
[22:37:21] <ssi> it means :D, plus an extra additional keystroke
[22:37:30] <PetefromTn> LOL
[22:37:30] <ssi> my typing fingers are out of practice
[22:37:45] <Connor> I get a smiley face graphic on my end. :)
[22:38:15] <PetefromTn> I was thinking of designing a cool looking mount for my keyboard tray to go beneath the pendant as a test project run.
[22:38:24] <Connor> PetefromTn: You find anything that can work as a lift plate?
[22:38:30] <ssi> PetefromTn: were you able to do anything with taht protram model?
[22:38:50] <PetefromTn> I need something that will allow me to tilt it and lock it in place.
[22:39:11] <PetefromTn> ssi No not yet, been working on the machine and trying to get these parts machined for a customer.
[22:39:17] <PetefromTn> Got it done this afternoon.
[22:39:22] <ssi> cool
[22:39:52] <PetefromTn> Not sure when I will machine that part and I apparently have to mod it so there is two spots for the grub screw right?
[22:40:53] <Connor> What? The protram ?
[22:40:58] <PetefromTn> yeah..
[22:41:13] <ssi> oh was that still missing?
[22:41:14] <ssi> I'm sorry
[22:41:15] <ssi> I can fix that
[22:41:26] <PetefromTn> no worries man. I can do it.
[22:41:36] <ssi> it was in the model, just suppressed for some reason
[22:42:06] <PetefromTn> honestly my 3d cad cam skills are rudimentary at best so it may be just a setting.
[22:42:22] <PetefromTn> I'll monkey with it after I get some other stuff done I need to do.
[22:42:32] <PetefromTn> I do appreciate the model tho man thanks.
[22:42:35] <ssi> sure thing
[22:42:37] <ssi> it was fun to draw
[22:43:17] <PetefromTn> Been sitting here racking my brain trying to come up with an uber cool product to make and start selling. Nothing jumping out at me yet.
[22:44:11] <PetefromTn> Gotta start making some parts and selling stuff so my wife does not think this whole mess was just a goof LOL.
[22:44:44] <PetefromTn> Anyone else cannot get on the CNCzone?
[22:47:25] <PetefromTn> http://www.haas.co.uk/images/rotary_images_large/T5C_4.jpg
[22:47:40] <PetefromTn> Check out this rotary unit...pretty sweet.
[22:57:06] <PetefromTn> hello?
