[00:00:12] <pfred1> wasn't the worst thing that went on there either by a long shot
[00:00:37] <XXCoder> hear4d could leave rock in fire for hours then throw it in water body glowing red
[00:00:38] <pfred1> unafuckingdilla!
[00:00:40] <XXCoder> and it'll explode
[00:00:49] <XXCoder> insane risk though lol
[00:01:04] <pfred1> oh the day of the races peole would show up in wheelchairs
[00:01:13] <pfred1> they were fine when they got to the event
[00:01:25] <pfred1> but they were always smiling
[00:01:38] <pfred1> we were pretty nuts
[00:02:01] <pfred1> we'd burn like 7 cars
[00:02:29] <pfred1> one while it was on fire someone wrapped a chain around it and dragged into the middle of the pond
[00:02:49] <pfred1> good samaratian? I don't think so!
[00:03:06] <pfred1> it was a Camero the next day it looked like an old Ford
[00:03:22] <XXCoder> crazy
[00:03:38] <pfred1> oh i saw stuff there that was just plain silly
[00:04:10] <pfred1> one guy was lighting some kind of fireworks on the roof of his pickup and he was all drunk and he was hitting this crowd of people
[00:04:21] <pfred1> they looked up at him and said, get some aim dude!
[00:04:43] <pfred1> to this day that still strikes me as so funny
[00:05:13] <pfred1> they burned one pick up and before they set it on fire they parkeed it on this tree that was in the crotch of another tree
[00:05:30] <pfred1> so while the truck was on fire they could lever it up and throw 20lb propane cylinders under it
[00:05:49] <pfred1> when they blew up they'd lift the whole truck up about 3 feet
[00:06:05] <pfred1> of course shrapnel would come out and hit folks in the crowd too
[00:06:14] <pfred1> but that's OK right?
[00:08:11] <pfred1> that event is televised it is amazing how networks can sanatize events for broadcast
[00:08:41] <pfred1> because on TV you never saw any of what went on
[00:09:01] <pfred1> while the guys were riding peole would throw explosives on the track
[00:09:37] <pfred1> amazing races
[00:09:50] <pfred1> the 250 GP has to be seen to be believed
[00:13:06] <PetefromTn_> Damn not sure what the layout should be for the buttons..
[00:13:25] <PetefromTn_> I got the MPG and the Estop drawn in
[00:13:30] <PetefromTn_> but now I am stuck LOL
[00:14:14] <pfred1> sleep on it
[00:14:52] <PetefromTn_> heh
[00:14:58] <PetefromTn_> I need to get to sleep actually
[00:15:00] <pfred1> they say if you think about something before you go to sleep you have a better view of it when you wake up
[00:15:10] <pfred1> I htink it is true too
[00:15:35] <pfred1> like right before you go to sleep try to envision it
[00:16:38] <pfred1> then the next day you'll have lots better ideas about it all
[00:16:50] <pfred1> it works
[00:30:48] <PetefromTn_> http://i.imgur.com/lLQw0oZ.jpg Pretty naked so far LOL
[00:57:46] <zeeshan|2> are you making a control panel?
[00:57:57] <PetefromTn_> yeah
[00:58:16] <zeeshan|2> nice :)
[00:58:18] <zeeshan|2> for the lathe??
[00:58:23] <zeeshan|2> btw any pics of the lathe after clean up
[00:58:27] <PetefromTn_> for the Cinci
[00:58:31] <PetefromTn_> not yet
[00:58:38] <PetefromTn_> still kinda torn apart LOL
[00:58:41] <zeeshan|2> hehe
[00:58:45] <zeeshan|2> how are the ways on it?
[00:58:54] <PetefromTn_> very good.
[00:59:07] <PetefromTn_> it looks like it was gently used for the most part
[00:59:22] <PetefromTn_> the machine has hardened ways too
[01:02:35] <zeeshan|2> nice
[01:11:08] <PetefromTn_> https://www.youtube.com/watch?v=o3-fZe05EMg Woah this looks like fun hehe Turbo rotary miata!!
[02:22:47] <Deejay> moin
[06:14:39] <Loetmichel> *HARHAR* walkera quadcopter has arrived... thats NOT so easy to fly whith an on-screen-remote on the Cellphone... -> https://www.youtube.com/watch?v=ra2cT5m3juI -co-worker cant do it better, either (yes, thats me ;-) -> https://www.youtube.com/watch?v=xqkEdzhDZjI
[07:01:54] <jthornton> anyone try dgarr/moveoff in ubuntu 10.04?
[07:02:08] <Tom_itx> not yet
[07:02:43] <jthornton> I think it works in Debian but I get an error on Ubuntu
[07:03:10] <jthornton> maybe I can make a simple thing today on the lathe LOL
[07:05:26] <Tom_itx> pm
[08:58:04] <JT-Shop> hmm my X offsets are screwed up again on the CHNC...
[08:59:04] * JT-Shop goes to walk the dog and ponder what I did wrong
[09:00:31] <archivist_herron> JT-Shop, how did you shut down
[09:07:56] <lair82> Does anyone know where to look at the man pages for dgarrett's moveoff stuff?
[09:21:55] <cradek> if you checkout and build that branch, you'll get a moveoff manpage
[09:22:24] <cradek> you might also be able to get packages from buildbot if that's your chosen poison
[09:26:46] <JT-Shop> I think it was a power glitch
[09:27:06] <cradek> I lost all my offsets to a space heater incident recently
[09:27:11] <cradek> it's very annoying
[09:31:36] <Jymmm> "space heater incident " Heh, that's funny the way you said it =)
[09:33:34] <Jymmm> "The Great space heater incident of 2014"
[09:43:08] <lair82> Do you know which branch it is under? I built the master branch and it's not there.
[09:43:20] <cradek> dgarr/moveoff
[09:43:56] <lair82> so it's not 2.
[09:44:05] <lair82> 2.7 or master?
[09:55:52] <cradek> nope, the branch is dgarr/moveoff
[09:58:49] <lair82> It's probably not, but, is it just doing " git branch dgarr/moveoff" from the terminal?
[09:59:30] <cradek> do it the same way as you do 2.7, except it's dgarr/moveoff
[09:59:47] <cradek> you'll probably use git checkout
[10:05:17] <jthornton> lair82, I used git checkout -b dgarr/moveoff origin/dgarr/moveoff
[10:08:11] <jthornton> for some reason my notes say to do that but not why
[10:10:43] <JT-Shop> do you guys have a trick for setting the X0 on a collet holder or keyless chuck on the lathe?
[10:11:46] <_methods> do you have a tool changer or are you doing tools 1 at a time?
[10:12:13] <lair82> And that should look like this " rick@rick:~/linuxcnc-dev$ git checkout -b dgarr/moveoff origin/dgarr/moveoff " correct?
[10:12:32] <cradek> JT-Shop: I just look at it with a loupe and eyeball the center
[10:12:47] <cradek> put something stubby in it like a spotting drill
[10:12:59] <_methods> oh X
[10:13:30] <JT-Shop> ok, I'll give that a try
[10:14:00] <_methods> yeah dowel pin works good too
[10:14:09] <_methods> sorry i had mill on the brain
[10:14:11] <cradek> lair82: I think that'll work
[10:16:28] <lair82> Ok I will give it a shot
[10:17:04] <cradek> in modern git versions I think you can just git checkout dgarr/moveoff and it'll give you a remote tracking branch like you want
[10:17:06] <PetefromTn_> Not CNC but I often use a small metal ruler to put between the tool edge and the side of a piece of round stock in the lathe
[10:17:21] <PetefromTn_> then raise or lower it until the ruler is vertical
[10:17:35] <cradek> PetefromTn_: he's mounting something like a drill chuck to the tool post and needs to center it crosswise
[10:17:46] <cradek> if I understood the question
[10:18:08] <cradek> he's got a turret
[10:19:49] <PetefromTn_> Not sure what kind of machine he has
[10:20:25] <PetefromTn_> just figured since X and Z are CNC controlled he must be talking about vertical height or center height but whaddahell do I kow LOL
[10:25:28] <DaViruz> my lathe doesn't have a tailstock, so i often clamp drill bits directly in the tool holder. a bit cumbersome but works pretty well
[10:25:59] <DaViruz> i've been thinking about making an attachment that fits a chuck, but so far it hasn't really been worth the effort
[10:26:01] <PetefromTn_> what kind of lathe?
[10:26:13] <DaViruz> it's homebuilt
[10:26:24] <PetefromTn_> really interesting
[10:26:25] <DaViruz> bought it from a deceased dentist
[10:26:50] <DaViruz> it's really nicely made, he must have had excellent skills
[10:26:55] <JT-Shop> cradek, thanks I'll update my notes for git
[10:27:27] <PetefromTn_> pics?
[10:27:30] <JT-Shop> PetefromTn_, it's a drill chuck on the turret of my CHNC
[10:27:37] <JT-Shop> and a collet holder
[10:27:45] <lair82> Learning all the time!!!
[10:28:23] <PetefromTn_> so you are trying to find the X0 location along the cross slide travel not vertical height then.
[10:29:06] <PetefromTn_> I have seen people put a DTI in the spindle on an articulated arm and pickup the tool body before.
[10:31:37] <DaViruz> anyone know anything about this machine? http://www.blocket.se/halland/Laser_mercury_l25_57468685.htm?ca=9&w=3
[10:32:03] <DaViruz> http://laserprouk.com/ seems to be the manufacturer, but they don't really have any information on this model
[10:33:27] <DaViruz> kinda been looking at the chinese 40-60W machines, but i don't really trust them
[10:33:34] <JT-Shop> yea that's what I did too
[10:35:21] <JT-Shop> mandrel is made now to see if I can make the part
[10:36:02] <lair82> I know the guys around here use the indicator trick and run the tip around the body of whatever it is ( drill, center drill, collet body ) to establish zero.
[10:37:18] <JT-Shop> I usually put a dowel in the chuck or collet holder and indicate that
[10:37:27] <_methods> yeah
[10:37:51] <_methods> i don't really know any better ways to do it
[10:38:51] <JT-Shop> PetefromTn_, I have a nifty Hardinge height gauge to set the tool height with
[10:39:00] <PetefromTn_> nice
[10:46:23] <cradek> you could also loosen the nut on the turret, put something nice in the spindle and the chuck, then tighten it in place
[10:46:57] <JT-Shop> that's a good idea
[10:47:34] <cradek> if it tightens down nice without twisting
[10:57:57] <PetefromTn_> Ooh cool Vince Guaraldi trio is on pandorah thanksgiving radio. Love the peanuts!! LOL
[11:07:21] <roycroft> pandora is useless now
[11:07:31] <roycroft> there was a report on the news this morning aboutit
[11:07:35] <PetefromTn_> why
[11:07:47] <roycroft> it doesn't pick playlists based on listener preferences any more
[11:07:52] <roycroft> it picks them based on revenue
[11:08:00] <roycroft> i.e. people pay to have certain songs on pandora
[11:08:24] <roycroft> not an unexpected turn of events
[11:08:37] <PetefromTn_> well I still listen to what I want and can thumbs down what I don't like
[11:08:53] <PetefromTn_> besides I usually like what they put on there
[11:09:09] <roycroft> and i bet your thumbs downs will slowly get ignored if you diss things they want you to hear
[11:09:14] <PetefromTn_> at least in the genres of music I listen to
[11:09:22] <PetefromTn_> probably
[11:09:27] <PetefromTn_> fuckers...
[11:09:34] <roycroft> i'm a crotchety old fart
[11:09:36] <PetefromTn_> ;)
[11:09:42] <roycroft> i listen to community radio stations
[11:09:48] <roycroft> and find new music on them
[11:09:51] <roycroft> and then buy cds
[11:09:56] <roycroft> physical cds
[11:10:03] <roycroft> then i rip them and make my own playlists
[11:10:03] <PetefromTn_> my music tastes are not what I would call mainstream LOL
[11:10:09] <roycroft> so 20th century, eh?
[11:10:12] <roycroft> nor mine
[11:10:48] <PetefromTn_> I must say that I do enjoy the holiday channels they create tho
[11:10:58] <roycroft> i do, for about the first 30 seconds
[11:11:06] <PetefromTn_> nice to be able to listen to Christmas music etc without loading CD's
[11:11:07] <roycroft> which, sadly, start before halloween now
[11:11:22] <roycroft> aah, there's the key for me
[11:11:32] <roycroft> i have everything ripped and imported into itunes
[11:11:41] <roycroft> i just make playlists and stream them
[11:11:44] <PetefromTn_> I despise Itunes...
[11:11:48] <roycroft> or load them on an ipod
[11:12:00] <roycroft> there are other music library management tools besides itunes
[11:12:07] <roycroft> the point is not itunes
[11:12:13] <PetefromTn_> but I do have every piece of music I own (and that's quite a bit) ripped to my phones and laptops, computers etc.
[11:12:17] <roycroft> but that i have everything available electronically
[11:12:36] <roycroft> when i get a new cd i rip it as soon as i get it
[11:12:49] <roycroft> and most of the time that's the last time the cd is every physically played
[11:12:52] <roycroft> ever
[11:12:54] <PetefromTn_> it's a new world in music today I think...
[11:12:59] <roycroft> yes
[11:13:13] <roycroft> people either rent or steal it these days
[11:13:37] <PetefromTn_> Wonderful to have such varied music without scratched CD's or cassettes and the ability to hold massive amounts of music on a tiny device
[11:13:43] <roycroft> back in the '70s/'80s there were all those lavish rock concerts
[11:13:48] <roycroft> huge sets, huge lighting shows
[11:13:55] <roycroft> a band would put out an album and do a mega tour
[11:13:59] <roycroft> the tour would lose money
[11:14:03] <roycroft> but it would promote album sales
[11:14:11] <roycroft> now there's no money in albums
[11:14:21] <roycroft> so the band tour to make money
[11:14:35] <roycroft> with a stripped down set
[11:14:40] <PetefromTn_> no skipping, no broken or stripped tapes no nothing but good music without issues...
[11:14:59] <PetefromTn_> my kids don't know how wonderful that is really...
[11:15:09] <roycroft> i do enjoy that aspect of it a lot
[11:15:30] <roycroft> however, my main stereo is a mid '70s vintage mcintosh system
[11:15:39] <roycroft> stacked advent speakers
[11:15:47] <roycroft> and there is no remote control for it
[11:15:58] <roycroft> i have to actually get up and walk across the room to adjust the volume
[11:16:11] <roycroft> people give me crap for that all the time
[11:16:22] <PetefromTn_> that and the fact that you don't have to drive to peaches or whatever to get access to a massive array of music most of which may have never even made it to a CD LOL
[11:16:37] <roycroft> i have a lot of downloaded music
[11:16:39] <_methods> mcintosh makes great stuff
[11:16:40] <PetefromTn_> mcintosh iis good stuff
[11:16:44] <_methods> hell yeah
[11:16:45] <roycroft> another great thing about this era
[11:16:47] <_methods> i wish i had one
[11:16:57] <roycroft> yes, my '70s mcintosh system sounds better than 98% of what's being made today
[11:17:00] <ssi> I want to build another amp soon
[11:17:19] <PetefromTn_> I have a Denon system with KEF speakers here nothing fancy but it sounds good.
[11:17:25] <roycroft> i have literally thousands of live concerts that i've downloaded
[11:17:43] <roycroft> back in the '70s all we could get were scratchy, low quality bootlegs of concerts
[11:17:46] <roycroft> on vinyl
[11:17:50] <_methods> i just pick up "old" new receivers anymore
[11:17:57] <_methods> i won't spend more than $300
[11:18:01] <PetefromTn_> one thing that sucks for me is I USED to have a bunch of cool concerts on VHS... now they are unusable..
[11:18:01] <roycroft> now people are able to plug into soundboards and get perfect recordings of the concerts
[11:18:37] <_methods> i'm just too lazy to be an audiophile anymore
[11:18:40] <roycroft> some of my favorite bands are best live
[11:18:45] <PetefromTn_> let alone my Star Wars and disney tapes...
[11:18:55] <roycroft> so it's nice being able to get the live concerts so easily
[11:19:06] <PetefromTn_> Gotta get them moved to another medium or something
[11:19:54] <roycroft> i have the three "real" star wars films on dvd, but never watch them because they're the reedited versions
[11:20:01] <PetefromTn_> I am sounding pretty old here I think LOL
[11:20:12] <roycroft> a friend of mine has them on laser disk, however, and i was able to rip them from laser disk
[11:20:20] <roycroft> and those are the versions that i watch
[11:20:46] <PetefromTn_> I contacted some jackhole on craigslist that had a nice blu ray set for sale but he never got back to me...
[11:20:51] <roycroft> han shot first, and lucas cannot get away with changing that :)
[11:21:00] <_methods> hahahahhah
[11:21:12] <PetefromTn_> lol
[11:21:19] <PetefromTn_> he sure as hell did.
[11:21:26] <PetefromTn_> not sure why he wanted to change the things he did.
[11:21:31] <PetefromTn_> most of it was kinda stupid
[11:21:36] <roycroft> perhaps i'm just rationalizing
[11:21:56] <roycroft> but i feel that since i actually purchased the dvd versions, ripping my friend's laserdisk versions isn't really pirating
[11:22:04] <PetefromTn_> why did we need to have a convo with Jabba the hutt before the millenium falcon takes off?
[11:22:34] <PetefromTn_> might as well have been pizza the hutt
[11:22:42] <ssi> _methods: personally I just like building crap, and if you do a little research and are handy at building crap you can make stuff that's far better than even most "audiophile" gear
[11:22:58] <roycroft> i just hope that some day we get the original releases in true hd
[11:23:05] <PetefromTn_> that would be sweet
[11:23:06] <_methods> yeah i've made some zaph speakers
[11:23:08] <roycroft> but that will probably have to wait until lucas is dead
[11:23:17] <roycroft> although now that disney own the franchise ...
[11:23:37] <_methods> i play around alot with the class d amps too
[11:23:40] <_methods> but nothing serious
[11:23:45] <roycroft> you'd be hard pressed to build an amp as good as a mcintosh
[11:23:46] <_methods> i want to build a nice tube amp one day
[11:23:53] <ssi> _methods: https://scontent-b-dfw.xx.fbcdn.net/hphotos-prn2/t31.0-8/857195_10100298818941952_1146233300_o.jpg
[11:23:54] <roycroft> and if you could, it would probably cost as much as a mcintosh
[11:24:03] <ssi> roycroft: you'd be surprised
[11:24:20] <jthornton> yuck it is sleeting
[11:24:26] <_methods> yeah that's beautiful
[11:24:47] <_methods> i want to sexy time your tube amp
[11:24:48] <ssi> _methods: 2A3 single ended triode, 2.5W/channel
[11:25:11] <ssi> drives a pair of markaudio alpair 10p in pensil cabinets, they're 95dB/W/m
[11:25:19] <ssi> very efficient fullrange speakers
[11:26:01] <ssi> it doesn't do super bass-heavy thumpy music as well as high power stuff, but it does unbelievable things with more natural recordings
[11:26:09] <roycroft> i have a turntable too
[11:26:16] <_methods> heheheh
[11:26:17] <roycroft> a friend of mine just gave me crap about that
[11:26:54] <roycroft> he's a vet who worked around loud guns a lot, and is mostly deaf
[11:26:57] <ssi> roycroft: http://www.kbapps.com/audio/schematics/tubeamps/mcintosh/images/mc40.gif get on it
[11:27:03] <roycroft> so he can't appreciate the quality of my hifi
[11:27:17] <ssi> push-pull 6L6 isn't a particularly exotic topology
[11:27:21] <_methods> hahah i remember when i was a kid we had a galaxy 500 station wagon with an 8 track in it
[11:27:37] <Jymmm> _methods: whats changed?
[11:27:45] <roycroft> i have an mr-73, a c-28, and an mc2100
[11:27:50] <_methods> i can't get 8 tracks anymore?
[11:28:00] <Jymmm> _methods: ebay?
[11:28:05] <roycroft> the mr-73 has a vacuum tube in it
[11:28:07] <_methods> hahah probably
[11:28:11] <_methods> i've never looked
[11:28:19] <_methods> that damn car was awesome
[11:28:21] <roycroft> a "magic eye" tube - it's the last tuner mcintosh made with a tube
[11:28:25] <Jymmm> _methods: There is one on 2.5 men, so whats your excuse?
[11:28:39] <_methods> 8 track or galaxy 500 lol
[11:28:45] <Jymmm> 8track
[11:28:52] <Jymmm> the old Panasoic ones
[11:28:59] <roycroft> i should get an 8track recorder
[11:29:16] <_methods> man my mom got the beegees on 8 track and she would wear that fucker out
[11:29:17] <roycroft> maybe stick an 8track player in my vw bus
[11:29:34] <_methods> i still cringe when i hear the beegees
[11:29:38] <ssi> 8 track wasn't actually ever good :P
[11:29:46] <roycroft> doobie brothers would be better than beegees
[11:29:59] <_methods> anything is better than beegees
[11:30:01] <roycroft> but in a vw bus you would not be able to tell the difference, ssi
[11:30:01] <jthornton> I asked Ohaus for the part number of the extra weights and they gave me a quote for $50... once I had the part number Amazon $42 free shipping
[11:30:07] <ssi> probably not!
[11:30:16] <Jymmm> _methods: https://www.youtube.com/watch?v=I_izvAbhExY
[11:30:17] <ssi> except it'd be more inconvenient :)
[11:30:29] <roycroft> inconvenient?
[11:30:32] <roycroft> but there's no flipping
[11:30:40] <roycroft> you just plug the tape in and plays, over and over and over
[11:30:40] <_methods> Jymmm: hahahha

[11:39:57] <PetefromTn_> great song
[11:40:06] <Jymmm> https://www.youtube.com/watch?v=x1p6Xbqrbx0
[11:40:12] <_methods> yeah i dig that song
[11:40:27] <PetefromTn_> when I was in the Coast Guard
[11:40:37] <PetefromTn_> I was stationed on the USCGC Steadfast
[11:40:46] <PetefromTn_> we had this guy named Robinson
[11:40:54] <PetefromTn_> He had an AMAZING singing voice
[11:41:10] <PetefromTn_> he would sing songs when we all were chilling out in our racks at night
[11:41:22] <PetefromTn_> he could sing the HELL out of that song by kansas
[11:41:29] <PetefromTn_> Every time I hear it I think of that
[11:41:30] <Jymmm> Great voice... https://www.youtube.com/watch?v=vCZ1YteCv5M
[11:44:34] <Jymmm> a great street performer... https://www.youtube.com/watch?v=M05NqpTCtvs

[11:54:00] <PetefromTn_> I don't understand what that linuxCNC clock radio thing is about...
[11:54:15] <Jymmm> bordom
[11:57:55] <PetefromTn_> I guess I am missing the point.
[11:58:15] <PetefromTn_> Basically everything it does my cellphone does better LOL
[11:59:10] <pcw_home> It probably spies on you a bit less
[11:59:21] <PetefromTn_> hehe
[11:59:26] <PetefromTn_> probably
[12:01:19] <_methods> it's just silly but cool
[12:01:43] <Jymmm> Hmmm, I need to find some LED drivers =(
[12:02:27] <PetefromTn_> Woohoo just received my 3/8 thick 12x36 acrylic plate from the Brown Santa LOL
[12:02:35] <ssi> love that guy
[12:03:42] <Jymmm> I swear, I have NFC how they are doing 3x 5Amp for such a tiny controller ((1sq in) WITH RF control.
[12:05:48] <Jymmm> 1/2" x 1.5" http://ecx.images-amazon.com/images/I/41sbMfR4kNL._SY300_.jpg
[12:06:06] <Jymmm> and a little over 1/8" thick
[12:06:26] <PetefromTn_> http://ken-gilbert.com/building-your-own-tube-amp
[12:08:17] <ssi> that looks an awful lot like mine :P
[12:10:09] <PetefromTn_> 300B SE sounds nice
[12:10:33] <ssi> I had plans to build a 300B SET amp
[12:10:43] <ssi> but I lost all the parts I had, including a pair of EH 300Bs
[12:11:35] <ssi> beware that the costs he has in his article are miserably out of date :)
[12:11:36] <PetefromTn_> 300B SE monoblock?
[12:11:49] <ssi> nah I wasn't gonna bother with a monoblock
[12:12:01] <ssi> I don't care enough about channel separation to make it worth the extra costs associated with monoblocks
[12:12:05] <PetefromTn_> monoblocks make me warm and fuzzy inside
[12:12:22] <archivist> audiophools
[12:12:31] <PetefromTn_> plus they just look impressive sitting there
[12:12:35] <PetefromTn_> ;)
[12:12:48] <PetefromTn_> archivist ?
[12:13:11] <ssi> archivist: zealotry on your end of the spectrum is just as ignorant as zealotry on the high-dollar audiophile end
[12:13:15] <archivist> built in wear and distortion
[12:13:49] <archivist> I used to do audio for a job
[12:14:03] <ssi> congrats, you and everyone else
[12:14:43] <PetefromTn_> what has built in wear and distortion?
[12:14:58] <archivist> tubes
[12:15:16] <archivist> the cathode wears with time
[12:15:18] <ssi> every amplification device has built in distortion
[12:15:32] <ssi> the trick is to use devices which have distortion which sounds pleasant
[12:15:57] <PetefromTn_> I dunno man I have been going to local audiophile meetings and the guys have some rather amazing sounding tube amp setups LOL
[12:16:49] <PetefromTn_> I must admit....I am diggin' it hehe
[12:17:27] <ssi> PetefromTn_: you figure out what you're gonna build yet?
[12:17:40] <PetefromTn_> Nope
[12:17:42] <PetefromTn_> :D
[12:17:51] <PetefromTn_> been too busy with other SCHTUFF
[12:17:56] <ssi> I hear that
[12:18:01] <PetefromTn_> installing Air Conditioning systems.
[12:18:05] <PetefromTn_> Trying to make money
[12:18:12] <PetefromTn_> refinishing my new CNC lathe
[12:18:17] <PetefromTn_> taking care of kids
[12:18:23] <PetefromTn_> ad nauseum
[12:18:24] <ssi> I'm buying a sb heavy ten on friday
[12:18:35] <PetefromTn_> neat
[12:18:42] <_methods> i thought it was a 10L?
[12:18:44] <ssi> it's pretty small, but it's a nice lathe
[12:18:47] <ssi> _methods: same thing
[12:18:53] <_methods> are you sure?
[12:18:54] <PetefromTn_> pics?
[12:19:04] <ssi> pretty sure?
[12:19:04] <_methods> i think the heavy 10 has a smaller spindle bore
[12:19:40] <ssi> PetefromTn_: best pic I have
[12:19:40] <ssi> https://pbs.twimg.com/media/B3N9f9VIcAAe1kx.jpg:large
[12:20:10] <PetefromTn_> is that the exact one?
[12:20:14] <_methods> i couldn't tell you without measuring the spindle bore
[12:20:15] <ssi> ya
[12:20:22] <PetefromTn_> interesting.
[12:20:32] <ssi> it's 1.39" bore
[12:20:33] <PetefromTn_> At least it has a QCTP
[12:21:39] <ssi> comes with a four jaw and TWO six jaw buck set-tru chucks
[12:21:46] <ssi> one of which is going promptly on my hardinge :D
[12:21:59] <ssi> I'm pretty sure the spindle nose thread is the same as the hnc
[12:22:00] <PetefromTn_> I love balanced ball handles ;P
[12:22:11] <_methods> yeah i think the 1.39 was the heavy 10
[12:22:21] <ssi> _methods: the 10K is the 1" bore one
[12:22:25] <ssi> but it's apparently fairly rare
[12:22:50] <PetefromTn_> it's funny it looks kinda small in that picture for some reason
[12:22:52] <ssi> also I'm not sure exactly what the length between centers is on this lathe, it's around 20" though
[12:23:03] <ssi> it's a "3-1/2' bed" lathe according to the placards
[12:23:10] <ssi> but that's the entire bed length
[12:23:27] <PetefromTn_> http://smg.photobucket.com/user/haplesspeanut/media/Main/EBAY10L.jpg.html
[12:23:35] <_methods> well there was a 10R, 10K and 10L i think
[12:24:13] <_methods> don't quote me on that though
[12:24:18] <_methods> either way it's a good find
[12:24:20] <ssi> yeah sounds righ
[12:24:29] <PetefromTn_> you really gonna build a 300B?
[12:24:34] <ssi> I dunno
[12:24:39] <ssi> I was gonna, back when I had parts for it
[12:24:41] <ssi> but I lost said parts
[12:24:55] <PetefromTn_> how much you figure it would cost?
[12:25:06] <ssi> probably close to a grand
[12:25:13] <PetefromTn_> jeez
[12:25:33] <ssi> 300Bs are expensive
[12:25:45] <ssi> the cheapest ones are the EH gold grid and they're $110 apiece, and you need two of them
[12:25:49] <ssi> for a SET stereo amp
[12:26:33] <PetefromTn_> is that Chinese?
[12:27:02] <ssi> I think the EHs are made by sovtek
[12:27:59] <PetefromTn_> What is the least expensive yet kickass way to arrive at a pair of nice monoblocks worth having LOL
[12:28:08] <ssi> here's some chinese ones
[12:28:08] <ssi> http://www.ebay.com/itm/2Pcs-new-Guiguang-300B-Shuguang-300B-matched-pair-tubes-/251676937629?pt=Vintage_Electronics_R2&hash=item3a991d4d9d
[12:28:22] <ssi> probably this:
[12:28:23] <ssi> http://diyaudioprojects.com/Tubes/EL84-Mini-Block-Amps/
[12:28:30] <ssi> I was gonna make those too... I had the transformers on hand
[12:28:32] <ssi> but I lost those too!
[12:28:33] <ssi> :(
[12:28:47] <PetefromTn_> thats a PP
[12:28:53] <ssi> yes, yes it is
[12:29:07] <ssi> 13:08 < PetefromTn_> What is the least expensive yet kickass way to arrive at a pair of nice monoblocks worth having LOL
[12:29:08] <PetefromTn_> wouldn't a SE be cheaper/better?
[12:29:12] <ssi> did not say anything about SE :)
[12:29:24] <ssi> cheaper, no... better? probably
[12:29:48] <PetefromTn_> same price or more
[12:29:59] <ssi> SE output transformers cost more
[12:30:12] <ssi> directly heated triodes cost a lot more
[12:30:25] <ssi> EL84s are like ten bucks apiece... 300Bs are over a hundred
[12:30:37] <ssi> chinese 2A3s are $70 apiece or so
[12:30:41] <ssi> that's what I started with in my 2A3 amp
[12:30:45] <PetefromTn_> you were gonna build those EL84 monoblocks then?
[12:30:49] <ssi> also, 2A3 sounds better than 300B, but makes less power
[12:31:00] <ssi> 45 sounds better than 2A3, but makes even less power
[12:31:06] <ssi> yea it was on my list
[12:31:20] <PetefromTn_> that's a long freakin' list :)
[12:31:20] <ssi> but now that I don't have the transformers anymore I'm not interested
[12:31:30] <ssi> like I said, I really don't care about monoblock as a design criteria
[12:31:38] <ssi> it just means building twice as many enclosures and twice as many power supplies
[12:31:44] <ssi> including buying twice as many power transformers
[12:32:39] <ssi> and I primarily play vinyl through these amps, and it's senseless spending all that time and money on monoblocks when the channel separation of a turntable cartridge is as poor as the channel separation of a single-psu amp
[12:33:00] <PetefromTn_> I know I am just a PIA
[12:33:14] <ssi> I mean you're more than welcome to build whatever you want :)
[12:33:22] <ssi> but just know that the cost will go up
[12:33:30] <PetefromTn_> I am gonna build SOMETHING at some point
[12:34:01] <PetefromTn_> I just don't wanna spend a lot of time and money to have something I am not just tickled pink with in the end.
[12:34:39] <PetefromTn_> the Knox area guys are planning another meet and listen session soon. Hopefully I can learn more about what I like and want then.
[12:40:56] <ssi> fwiw
[12:40:57] <ssi> https://www.edcorusa.com/dap-200
[12:41:10] <ssi> that's the xfrm kit for that el84 pp monoblock
[12:41:20] <ssi> $150 for a full set of monoblock iron is absurdly inexpensive
[12:41:33] <PetefromTn_> is it garbage?
[12:41:35] <_methods> damn shipping is hell too
[12:41:44] <ssi> EL84s are as cheap as $9.98 apiece, and you need four of them
[12:41:47] <_methods> transfromers are a bitch cause of the weight
[12:41:47] <ssi> is what garbage
[12:41:51] <ssi> your attitude?
[12:42:22] <PetefromTn_> ?
[12:42:47] <ssi> _methods: I haven't had problems with shipping costs on transformers
[12:42:50] <ssi> they're heavy, but they're not THAT heavy
[12:43:19] <ssi> $22.41 to ship two sets of those edcor xfrms to me via ups ground
[12:43:29] <_methods> yeah i'm used to free shipping lol
[12:43:32] <ssi> what's worse than the shipping is the fact that edcor makes everything to order, so it's like four weeks lead
[12:43:41] <_methods> ouch
[12:43:47] <ssi> erg, says 6-8 weeks now
[12:43:48] <ssi> that sucks
[12:44:08] <ssi> edcor makes good stuff, but I hate waiting like that
[12:44:15] <_methods> toroidals or E type
[12:44:21] <ssi> EI
[12:44:37] <ssi> you can't really do toroidal SE output transformers
[12:44:39] <ssi> they have to be gapped
[12:44:52] <ssi> there are C core SE OTs, like the lundahls
[12:45:09] <_methods> yeah i don't know anything at all about SE
[12:45:29] <_methods> only amps i've ever messed with were D class
[12:45:35] <ssi> single ended amps are pure class A, and they're biased about halfway up the B+
[12:45:42] <ssi> which means you have current in the OT at quiescence
[12:45:50] <ssi> that makes the transformer saturate
[12:45:56] <ssi> so they have to be designed to deal with that
[12:46:03] <ssi> bigger iron and gapped cores typically
[12:46:17] <ssi> makes SE OTs more expensive per power handled/freq response than PP OTs
[12:47:18] <ssi> low end response is directly proportional to primary inductance in the OT, and primary inductance is directly proportional to the amount of copper and core in the transformer
[12:47:27] <ssi> cost and weight are directly proportional to the amount of copper and core
[12:47:36] <ssi> so low end power handling == $$$
[12:49:00] <ssi> this is a good paper
[12:49:01] <ssi> http://lundahl.se/wp-content/uploads/2013/06/cb-amplifier_8wse.pdf
[13:17:17] <lair82> Does anyone know the best way to confer back and forth with Dewey Garrett? I have been playing with his moveoff feature and have some questions.
[13:18:51] <JT-Shop> he does post on the forum
[13:20:12] <lair82> Ok, I will hit the forum,
[13:20:29] <lair82> Thanks Guys, and Happy Thanksgiving!!!
[13:40:32] <ekacnet> hi all
[13:40:46] <ekacnet> is the usb port of 7I43-U usable in linuxcnc
[13:40:55] <ekacnet> or I have to stick to the // interface ?
[13:41:26] <jdh> pport
[13:41:37] <jdh> or get a pci/pci-e card
[13:47:07] <ekacnet> jdh ok, I wasn't sure for convience I still use laptop
[13:47:20] <ekacnet> so // starts to be more difficults to get
[13:50:27] <Rab> ekacnet, see e.g. http://www.amazon.com/StarTech-com-ExpressCard-Parallel-Adapter-EC1PECPS/dp/B001Q7X0W6
[13:50:55] <ekacnet> Rab: I have one of those already
[13:51:10] <Rab> ekacnet, how does it work?
[13:51:13] <ekacnet> just wondering as this card has both interface
[14:11:32] <jdh> laptops are not usually good choices for linuxcnc.
[14:18:52] <SpeedEvil> yeah.
[14:19:13] <SpeedEvil> Now that inexpensive x86 tablets are coming out, they are clearly the better choice.
[14:19:57] <SpeedEvil> https://www.indiegogo.com/projects/jolla-tablet-world-s-first-crowdsourced-tablet#home (no, not really)
[14:25:34] <Tom_itx> JT-Shop, if you mill that on a mandrel won't it unscrew when you machine it? unless you run the spindle backwards
[14:26:47] <LeelooMinai> Not how much money the rised
[14:26:50] <LeelooMinai> Note*
[14:27:54] <LeelooMinai> They probably have a party right now jumping with excitement like monkeys:)
[14:31:20] <JT-Shop> Tom_itx, not on a front tool lathe
[14:31:28] * JT-Shop almost has a ball
[14:32:19] <SpeedEvil> Does it have nice seams?
[14:33:24] <Tom_itx> JT-Shop, what did that last code look like?
[14:33:55] <JT-Shop> my code?
[14:34:07] <Tom_itx> no the code i posted just before i left
[14:34:23] <Tom_itx> swapped ends and used a mandrel
[14:37:18] <andypugh> I am always scared of using a mandril by mistake.
[14:37:28] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/
[14:37:31] <andypugh> http://en.wikipedia.org/wiki/Mandrill
[14:38:33] <JT-Shop> I missed it
[14:38:41] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/17mm_ball_test.jpg
[14:39:39] <JT-Shop> radius errors
[14:39:46] <Tom_itx> crap
[14:39:50] <Tom_itx> what line?
[14:40:11] <JT-Shop> you program that in radius mode or diameter mode?
[14:40:31] <Tom_itx> well i think the cutter is off
[14:40:49] <Tom_itx> and tbh i'd have to look
[14:41:08] <PetefromTn_> what program is that?
[14:41:17] <Tom_itx> smartcam lathe
[14:41:24] <PetefromTn_> ok
[14:42:57] <Tom_itx> i'll work on it tonight. i just wanna see it work even if you get yours done
[14:43:26] <Tom_itx> late lunch and back to work...
[14:45:42] <jdh> work?
[15:14:05] <JT-Shop> I'm trying to build a RIP of dgarr/moveoff on this debian box and get checking for tcl... tclConfig.sh not found when I run ./configure
[15:17:03] <t12_> pin/hole question
[15:17:23] <_methods> well when a man and a woman.......
[15:17:30] <t12_> i have a thin part, .75-1mm, and i'm thinking of pressing really shallow (1-1.5mm tall) pins in
[15:17:33] <t12_> do i have any hope?
[15:17:45] <t12_> (kinematic stops)
[15:18:12] <andypugh> You see that in clocks and watches
[15:18:49] <andypugh> But I think I would rivet into back-countersunk holes.
[15:19:43] <t12_> hmm
[15:20:39] * JT-Shop wanders off to see what the neighbors are doing
[15:21:37] <t12_> this slide holder is kinda rough
[16:13:51] <Deejay> gn8
[17:12:23] <Tom_itx> JT-Shop, i think i fixed the errors
[17:12:30] <Tom_itx> it was a precision thing in the cam post
[17:12:40] <Tom_itx> the last one i ran loaded fine
[17:15:26] <JT-Shop> this is baffling my X offset is screwed on tool 4 again
[17:16:29] <Tom_itx> care to load this and see what it looks like?
[17:16:48] <andypugh> JT-Shop: Did you notice that Dewey’s Axis has separate buttons for axis and tool touch-off?
[17:24:13] <cradek> andypugh: that's a 2.7 feature
[17:24:25] <andypugh> Ah, OK.
[17:24:55] <andypugh> I think my Lathe is on 2.5 and my Mill in something JA-ish and running Touchy.
[17:25:51] <cradek> all my actual machines are out of date too, except the desktop mill I've been using lately
[17:26:02] <cradek> the vmc might be 2.4
[17:26:15] <cradek> works perfectly :-)
[17:26:17] <andypugh> If they work, then that’s all that matters
[17:26:27] <cradek> actually no, I noticed a bug last time I used it
[17:26:54] <cradek> if I turned on the pause switch (touchy) during a g4 it was ignored
[17:27:10] <cradek> another terrible task bug of course
[17:27:12] <andypugh> Beat the Touchy author
[17:27:23] <cradek> heh I doubt it's touchy
[17:28:13] <JT-Shop> andypugh, no, I did not notice... I get an error trying to run it on Ubuntu
[17:28:52] <andypugh> I need to add a gremlin tab to touchy, and a probing / drilling / straight-feed tab, then it will be perfect.
[17:28:55] <shaun414> hi
[17:29:05] <andypugh> Hi
[17:29:08] <shaun414> what do you guys think could imporve 3d printing?
[17:29:25] <cradek> 10 years
[17:29:29] <shaun414> why
[17:29:45] <andypugh> Mono-isotopic single-crystal diamond printing.
[17:29:51] <_methods> a small thermonuclear warhead?
[17:29:52] <shaun414> heh
[17:30:06] <cradek> andypugh: mine'll happen
[17:30:18] <_methods> public execution of the makerbot guy?
[17:30:39] <shaun414> id agree
[17:30:43] <shaun414> death to bre
[17:30:44] <andypugh> Mine might, but yours will happen sooner.
[17:31:22] <shaun414> what can help with bed adhesion?
[17:31:23] <andypugh> Seems a little harsh.
[17:31:24] <shaun414> or speed?
[17:31:52] <andypugh> I would go for “minor discomfort to 3D Systems until they lighte up on some patents”
[17:32:54] <andypugh> 3D printing is already pretty good, if you have the right printer.
[17:33:19] <andypugh> There is a lot of difference between GGG printers and the stuff we have at work.
[17:33:36] <shaun414> heh
[17:33:49] <shaun414> im tryin to find ways to improve it
[17:34:05] <andypugh> We print 100% functional car parts, and have printers that print sand moulds for cylinder block and head castings.
[17:34:51] <andypugh> If I was to build a printer it would probably be a sand-mould printer, as I mainly want functional parts in metal.
[17:35:10] <shaun414> how would you do that
[17:35:31] <shaun414> i have an old 3d priner i kinda want to make into a cnc router
[17:35:35] <shaun414> think thats possible?
[17:35:39] <andypugh> I would shamelessly copy what the commercial printers do, and not tell them.
[17:35:51] <shaun414> true
[17:36:38] <andypugh> What do you want to rout? Foam would be OK. Tool steel might be a struggle.
[17:37:49] <shaun414> wood
[17:37:54] <andypugh> My favourite router: http://youtu.be/quN37YskoaM
[17:38:21] <shaun414> lmao that is awesome
[17:39:43] <JT-Shop> Tom_itx, sure
[17:39:50] <Tom_itx> same link
[17:40:06] <Tom_itx> i cleared out all but it
[17:41:14] <andypugh> I want a milling machine that walks away and says “see what I just did” when finished :-)
[17:41:40] <shaun414> i just want a milling machine
[17:41:59] <shaun414> how cheap for one?
[17:42:07] <shaun414> would belt driven suck?
[17:42:59] <andypugh> I paid £700 for a 1970s “real” milling machine and about anouther £1000 on parts to CNC it.
[17:44:26] <andypugh> There are cheaper ways. Laurent Parti makes surprisingly nice parts on an all-wood machine: http://youtu.be/FXc2CcDkY5s
[17:46:54] <andypugh> And that machine seems to be all-belt
[17:47:35] <SpeedEvil> andypugh: yeah - I've been wondering about that.
[17:47:41] <SpeedEvil> Plywood is shit.
[17:47:48] <SpeedEvil> It's 1/200th as rigid as steel.
[17:48:13] <andypugh> Indeed, but he has made parts, and they look OK
[17:49:17] <SpeedEvil> But - boost the beam thickness by 3.5* and you're there
[17:50:09] <SpeedEvil> The amount of wood needed to not deflect .1mm under 100kg of cutting force over a 1m span isn't really that high
[17:50:16] <andypugh> MDF has a modulus of 4GPa, and Steel is 200, so it’s not quite as bad as you say
[17:50:44] <SpeedEvil> yeah - I was basing measurements of this really really shitty plywood I've gotten, probably in the bendy direction
[17:51:11] <SpeedEvil> Properly treated decent wood gets rather better
[17:51:19] <SpeedEvil> thermally treated wood has interesting properties
[17:51:22] <SpeedEvil> but is more complex
[17:52:07] <andypugh> Oak is 11, aluminium is 69. I imagine solid hardwood approaches extruded Aluminium section for stiffness.
[17:53:31] <andypugh> I believe in Laurent’s machine but his hold-down clamps are horrible :-)
[17:55:27] <SpeedEvil> yeah
[18:07:42] <JT-Shop> yuck it will take 20 minutes to view Laurents 5 minute video
[18:07:44] <LeelooMinai> ironwood:)
[18:08:22] <MrSunshine> ball nosed router bits ... can they be flat on the end ?
[18:08:35] <MrSunshine> having trouble making lithophanes with one ... stuff gets distorted and blobbed.. :/
[18:08:42] <SpeedEvil> MrSunshine: if you have flat balls
[18:08:47] <LeelooMinai> WIth some file work, sure they can?
[18:08:57] <andypugh> No. If they are they are not ball-nose, they are bull-nose
[18:09:15] <JT-Shop> can't file an end mill unless you anneal it first
[18:09:20] <_methods> heheh
[18:09:24] <_methods> file an endmill
[18:09:25] <_methods> lol
[18:09:29] <LeelooMinai> With a diamond file? :)
[18:09:31] <SpeedEvil> JT-Shop: Racist!
[18:09:35] <SpeedEvil> Diamond files are files too!
[18:09:41] <MrSunshine> SpeedEvil, humm ? it says 3.2mm 1.6mm Radius ... so i figure it shouldnt be flat at the end :P
[18:09:41] <SpeedEvil> argh - beaten to it
[18:10:23] <JT-Shop> use an angle grinder why waste time with a file
[18:10:57] <andypugh> MrSunshine: http://stores.ebay.com/espeil2014/Corner-Radius-3T-/_i.html?_fsub=6926758014
[18:11:01] * JT-Shop wanders away
[18:18:23] <andypugh> Sleep time. Night all
[18:20:28] <MrSunshine> ye those are bullnosed .. they i know are flat .. mine is a ball end mill .. oh well have to check it tomorrow .. gonna take a photo of it and compare it to a circle in cad program .. then i will have black on white if its flat at the end or not =)
[18:21:39] <_methods> you're just trying to determine if it has a flat on it?
[18:23:39] <MrSunshine> ye
[18:23:53] <_methods> takin a pic and comparing it to a circle is probably the best way to go
[18:24:05] <_methods> unless you have an optical comparator laying around
[18:24:34] <_methods> you could run it along something and check the path with a radius gauge
[18:24:50] <_methods> if you have radius gauges
[18:24:55] <MrSunshine> do not have radius guage so i guess the best check i can do is to photograph it and compare it
[18:25:15] <_methods> yeah you need to make sure the camera is square to the mill
[18:25:30] <_methods> or you could cause a parallax error
[18:25:36] <_methods> i think it's parallax?
[18:25:43] <Jymmm> Put a steel rule on it
[18:26:13] <Jymmm> that will give you scale in the photo to resize as needed.
[18:27:05] <Tom_itx> use a 1" marble
[18:27:13] <Jymmm> and a silver dollar is exactly 1.5" =)
[18:28:02] <Jymmm> 6" steel rule works good, as it has the graduations on it
[18:28:43] <Tom_itx> gawd everybody's in a hurry tonight...
[18:28:47] <Tom_itx> traffic was nuts
[18:28:54] <Jymmm> just lock the H/W when resziing photo
[18:29:05] <_methods> https://www.youtube.com/watch?v=wtProYWkpcM
[18:29:13] <_methods> in honor of thxgiving
[18:29:14] <Jymmm> Yeah it was, couldn't go faster than 70MPH
[18:29:30] <Jymmm> 80MPH on the way back
[18:29:53] <Jymmm> Oh, be warned...
[18:30:32] <Jymmm> If you exchange propane tanks at Lowes/Blue rhino, they are now RECERIFYING tanks, which are only good for 5 year instead of ten.
[18:30:40] <_methods> oh wtf
[18:30:51] <_methods> i'll just get big tanks and refill my own now i guess
[18:30:53] <Jymmm> Look for the double date stamps
[18:30:54] <_methods> assholes
[18:31:42] <Jymmm> It's still good for exchange, I did find a JUNE 2014 single date tank
[18:32:09] <Jymmm> But do keep an eye out for RECERTIFIED (dual dates)
[18:32:30] <_methods> thx for the heads up
[18:33:23] <Jymmm> _methods: and the date has moved on the collar for 2014
[18:33:34] <Jymmm> _methods: it's closer to the TW
[18:37:09] <Jymmm> _methods: Original FEB1998+10 = EXP FEB2008. RECERTIFIED MAY 2012 + 5 = EXP MAY2017
[18:37:13] <Jymmm> http://www.thurstontalk.com/wp-content/uploads/2012/05/2012-05-29_13-05-58_985.jpg
[18:37:54] <MrSunshine> Jymmm, i know the dia of the mill so i guess that should be good enough to check if its flat on the end :P
[18:38:59] <Jymmm> MrSunshine: I try to have things of know diameter around for such things =)
[18:39:18] <Jymmm> MrSunshine: I keep a silver dollar in the desk drawer as example
[18:41:21] <Jymmm> _methods: http://junkyardsports.com/images/piggas.jpg
[18:51:25] <_methods> hahahah now that's a tank
[18:52:57] <Jymmm> Sorry, it's 12 years, not ten
[18:57:48] <Aero-Tec> got to love windows
[18:58:06] <Aero-Tec> I have the lathe and mill hooked up to a network
[18:58:09] <Jymmm> Aero-Tec: The oldest and most profitable virus still going.
[18:58:18] <Aero-Tec> I can see the mill but not the lathe
[18:58:40] <Aero-Tec> every thing was working great till a power bump
[18:58:52] <Aero-Tec> so restarted everything
[18:59:24] <Aero-Tec> now I can see the mill but not the lathe
[18:59:44] <Jymmm> Aero-Tec: How? ping? windows explorer?
[18:59:47] <Aero-Tec> but if I go into my history I can find where I was accessing the lathe
[19:00:13] <Aero-Tec> click on it and the lathe is now accessible
[19:00:20] <Aero-Tec> explorer
[19:00:43] <Jymmm> and what are the mill/lathe runing linux?
[19:00:54] <Aero-Tec> thing is doing a refresh in the network window and lathe is still missing
[19:00:59] <Aero-Tec> yes
[19:01:06] <Aero-Tec> linuxcnc
[19:01:26] <Jymmm> I blame the operator for that.
[19:01:44] <Jymmm> you didn't configure SMB for master browser
[19:01:45] <Aero-Tec> so with a history link I can get to lathe but the networking part of windows does not see it
[19:02:00] <Aero-Tec> ?
[19:02:16] <Aero-Tec> I had no problems before power bump
[19:02:19] <Jymmm> It's not like DNS
[19:02:24] <Aero-Tec> always worked fine
[19:02:48] <Aero-Tec> been doing this for over a year
[19:02:59] <Jymmm> and what do you have for DNS for all three machines?
[19:03:12] <Aero-Tec> just funny that now it does not show up but I can still get to it
[19:03:29] <Jymmm> yep, that makes sense.
[19:03:39] <Aero-Tec> what every the default was I guess
[19:03:57] <Aero-Tec> whatever
[19:04:24] <Aero-Tec> I did not mess with the DNS for linux
[19:04:40] <Jymmm> and you did for windows?
[19:04:46] <Aero-Tec> may have for windows, not sure been awhile if I did
[19:05:29] <Aero-Tec> the other my test machine show fine
[19:05:40] <Aero-Tec> oops
[19:05:52] <Aero-Tec> my code testing machine
[19:07:55] <Aero-Tec> funny the code testing machine does not see the lathe ether
[19:08:01] <Aero-Tec> it is linuxcnc
[19:14:16] <Aero-Tec> same thing
[19:14:55] <Aero-Tec> should I be restarting the lathe computer?
[19:15:27] <Aero-Tec> any ideas as to why the lathe is hidden?
[19:16:47] <Aero-Tec> should I be messing with the DNS?
[19:19:27] <Aero-Tec> other then installing it I have not messed around with SMB
[19:20:25] <Aero-Tec> not sure how one would setup master browser, or even what the means
[19:35:42] <Jymmm> Aero-Tec: http://ubuntuforums.org/showthread.php?t=1524474
[19:36:06] <Aero-Tec> got to love power bumps
[19:36:50] <Aero-Tec> my code test machine was not showing all the stuff it used to in linux window
[19:37:00] <Aero-Tec> so rebooted
[19:37:27] <Aero-Tec> now says error in HD
[19:37:50] <Aero-Tec> I hit f for fix
[19:37:59] <Aero-Tec> and that did not help at all
[19:38:41] <Aero-Tec> ok so I did a few restarts of it and now it is doing a check dish run
[19:38:48] <Aero-Tec> disk
[19:38:50] <Aero-Tec> lol
[19:39:50] <Aero-Tec> so it started but the icons along the top like time and stuff are missing
[19:40:24] <Aero-Tec> also the tool bar at the bottom is blank
[19:40:38] <Aero-Tec> no switch windows and stuff
[19:42:23] <Aero-Tec> just desktop icons and the stuff on the top left, also has the firefox icon and help on the left
[19:42:51] <Aero-Tec> anyway to get the default stuff back?
[19:47:06] <Aero-Tec> messed with it some and found out how to add things
[19:51:28] <Aero-Tec> Jymmm, thanks for the info
[20:00:14] <LeelooMinai> What is the name for those things one can put into a collet and it will detect edges of metal opbjects and hopefully lets linuxcnc know where they are?
[20:00:33] <Tom_itx> touch probe
[20:01:05] <LeelooMinai> O, right. ANy comments on them? Are they fully suported/useful?
[20:01:25] <Tom_itx> uh huh
[20:02:30] <Jymmm> edge finder?
[20:02:35] <Jymmm> electronic edge finder?
[20:03:28] <LeelooMinai> I think I have some edge finder thing with some metal disk, but I don't think it's designed to work with something like linuxcnc
[20:04:22] <Aero-Tec> well things are working now, it fixed itself
[20:04:24] <LeelooMinai> It's more for some manual technique, I forgot now:)
[20:05:02] <Aero-Tec> all I did was restart the test computer a few times and do a refresh in the windows network window
[20:05:16] <Aero-Tec> it all show up like it should
[20:07:33] <Aero-Tec> still having some problems with the lathe code
[20:07:36] <Aero-Tec> http://pastebin.com/giquCv6b
[20:07:55] <Aero-Tec> it does work at times
[20:08:17] <Aero-Tec> but errors every so often
[20:08:48] <Aero-Tec> it goes to
[20:08:50] <Aero-Tec> Z0.75
[20:08:50] <Aero-Tec> X3.25
[20:08:58] <Aero-Tec> and errors
[20:09:10] <Aero-Tec> has done it 3 times so far
[20:09:28] <Aero-Tec> but I have made over 30 parts
[20:09:39] <Aero-Tec> so it has worked most of the time
[20:09:55] <Aero-Tec> posted the part of the code that errors
[20:10:28] <Aero-Tec> fresh eyes would be gladly welcomed
[20:11:47] <Aero-Tec> some one said I should not use - in place of _ in variable names so I changed that
[20:13:02] <Aero-Tec> this last time is complained about #<SPINDLE_SPEED> variable
[20:13:18] <Aero-Tec> before it would complain about some letter
[20:13:28] <Aero-Tec> so it has got better
[20:14:05] <Aero-Tec> the letters were e and I believe t
[20:14:37] <_methods> what are you using to post?
[20:14:43] <Aero-Tec> did not make sense
[20:15:01] <Aero-Tec> post?
[20:15:07] <_methods> yes post process
[20:15:11] <Aero-Tec> you meant to write and save the code?
[20:15:16] <_methods> yes
[20:15:21] <Aero-Tec> I hand code
[20:15:33] <_methods> ah
[20:15:38] <Aero-Tec> all hand coded
[20:15:39] <_methods> link to your code?
[20:16:11] <Aero-Tec> http://pastebin.com/giquCv6b
[20:16:50] <Aero-Tec> section of code where error hits
[20:17:00] <_methods> um you should probably put some basic safety stuff in your code
[20:17:06] <Aero-Tec> all 3 times in the exact same spot
[20:17:38] <Aero-Tec> does the
[20:17:40] <Aero-Tec> G0
[20:17:40] <Aero-Tec> Z0.75
[20:17:40] <Aero-Tec> X3.25
[20:17:51] <Aero-Tec> moves and then stops
[20:18:09] <Aero-Tec> not sure why
[20:18:17] <_methods> why do you have semicolons in front of your lines?
[20:18:33] <Aero-Tec> rems out the line
[20:19:04] <_methods> well standard practice to to put your EOL at the end of each line
[20:20:16] <_methods> is a m30 or m2 not reqd by linuxcnc?
[20:20:43] <_methods> are you using incremental or absolute?
[20:20:54] <Aero-Tec> that is just a code snippet the m30 is later on
[20:21:17] <Aero-Tec> both at times, mostly abs
[20:21:29] <_methods> well what's active when your program starts
[20:21:36] <_methods> that could be causing you problems
[20:21:37] <Aero-Tec> inc is just for small sections so far
[20:21:53] <Aero-Tec> abs
[20:21:54] <_methods> well if inc is still active when you call that abs at the top of the prog.............
[20:22:17] <Aero-Tec> I have a INI
[20:22:47] <_methods> you have startup code in your ini?
[20:22:50] <Aero-Tec> ;CODE START
[20:22:51] <Aero-Tec>
[20:22:51] <Aero-Tec> G18 G40 G49 G90 G94 G80
[20:22:51] <Aero-Tec> M3
[20:22:51] <Aero-Tec> G20
[20:22:51] <Aero-Tec> G95
[20:22:53] <Aero-Tec> yes
[20:23:02] <Aero-Tec> every time
[20:23:14] <Aero-Tec> it is part of the gcode
[20:23:22] <_methods> kk
[20:24:44] <_methods> well i have no idea but this looks like it might cause a problem
[20:25:13] <_methods> ;G0 X[#3+#4]
[20:25:14] <_methods> G0 X[#<_RAIDIUS_OF_STOCK>+#<_CUT_START_OFFSET>] Z[-0.635-#<WIDTH_OF_CUTOFF_BLADE>]
[20:25:23] <_methods> looks like you have 2 rapids on the same line
[20:25:34] <_methods> 2 x rapids
[20:26:21] <Aero-Tec> how can that be 2 rapids on the same line?
[20:26:24] <renesis> i dont see whatever you are seeing that
[20:26:34] <Topy44> i mentioned a pcb i was designing a few days ago, a safety- and interface-board for our linuxcnc-controlled laser cutter
[20:26:42] <renesis> one looks commented out and even if it wasnt it would run fine?
[20:26:44] <Aero-Tec> one line is remed out
[20:26:54] <renesis> even if it wasnt
[20:27:01] <_methods> oh i'm so used to ; as EOL
[20:27:07] <renesis> nothing wrong with g0 two lines in a row
[20:27:12] <Topy44> that goes absolutely sure that the laser cannot be turned on unless everything is ok (no endstop switches activated, lid closed, exhaust and cooling systems running, etc.)
[20:27:14] <_methods> that's an EOL on a real cnc
[20:28:26] <Topy44> and also handles controlling stuff like the interior lights, air assist and cooling as well as the rs485-controlled exhaust system from linuxcnc, plus giving back a ton of status info back to linuxcnc
[20:28:26] <Aero-Tec> I have used that for lots of hand coding of emc
[20:28:36] <Topy44> anyway. i just finished the pcb layout
[20:28:46] <Topy44> *drumroll* ...here it is: http://t44.org/dump/2014-11-27_02-44-33.png
[20:29:13] <Aero-Tec> never was a problem yet
[20:29:23] <Aero-Tec> not that I know of anyway
[20:29:31] <_methods> yeah i have no idea if it worked before
[20:29:33] <LeelooMinai> Topy44: Looks nice
[20:29:47] <Topy44> and an eye-candy rendering of it: http://t44.org/dump/2014-11-27_02-57-25.png
[20:30:19] <Topy44> all safety-relevant stuff is implemented in proper logic (not µC firmware), and all inputs are very, very well protected
[20:30:54] <LeelooMinai> Topy44: You don't trust the code? :p
[20:31:15] <Topy44> nope :) but more importantly: i don't trust a microcontroller to not mess up if it gets a nasty esd spike or something
[20:31:15] <Aero-Tec> only 3 errors and I made 30 parts with out any error stoppage
[20:31:35] <Aero-Tec> it stops when there is a error
[20:31:46] <XXCoder> easy, never power it. ;) topy jk
[20:32:11] <LeelooMinai> Topy44: Is it some big laser cutter?
[20:32:16] <Topy44> if it skips a couple instructions or something it might "forget" that the lid is open or that an endstop was activated and self destruct or burn someone's eye out :)
[20:32:18] <PetefromTn_> I don't understand your problem. If the code runs thru most of the time how could the problem be the code? What kind of error are you talking about?
[20:32:53] <_methods> do you initialize all your variables at the beginning of your code somewhere?
[20:33:03] <Aero-Tec> yes
[20:33:06] <LeelooMinai> Well, hard-wiring it is more foolproof indeed
[20:33:07] <_methods> hmm
[20:33:23] <Topy44> LeelooMinai: well, its bigger than most "hobbyist" machines but still relatively small. 120x70cm working area, 60W co2 laser (we want to upgrade it to 120W soon-ish)
[20:33:31] <Aero-Tec> last error was complaining about #<SPINDLE_SPEED>
[20:33:41] <Aero-Tec> not set or not defined
[20:33:59] <Aero-Tec> I can see if I cleared it or if it is still showing
[20:34:21] <Topy44> the whole project will be GPL-ed once the boards are ready and the firmware and corresponding userspace component is done
[20:34:31] <_methods> only thing i can think is something funky is in one of your variables?
[20:34:34] <LeelooMinai> All those mirrors and delicate tubes. I wish 60watt laser diodes vere cheap and available - I would just attch it to my cnc platform and have laser-cutter
[20:34:43] <Topy44> and i'll throw the leftover boards on tindie, in case someone else abuses linuxcnc for a laser cutter :)
[20:35:02] <Topy44> LeelooMinai: well, you also need an enclosure
[20:35:05] <LeelooMinai> Hmm, laser cutting is cnc too
[20:35:20] <Topy44> a 60W laser could quiet seriously burn your skin or blind you pretty much instantly
[20:35:37] <LeelooMinai> Topy44: Yes, I plan to make one anyways - as the platform is in my bedroom/liferoom/nerdcave
[20:35:40] <Topy44> (oh, and its completely invisible, for that extra bit of fun)
[20:36:18] <LeelooMinai> I would not operate a laser without some super-safe anclosure and camera inside it
[20:36:29] <Topy44> no need for a camera
[20:36:36] <LeelooMinai> Well, camera would be nice
[20:36:39] <Topy44> just get IR-opaque plastic shielding
[20:36:45] <SpeedEvil> The onlky eye-dangeroud bit of a CO2 laser is where it's collimated
[20:36:54] <SpeedEvil> once it goes through a lens - it's not an issue
[20:37:08] <Topy44> true
[20:37:09] <SpeedEvil> well - unless you've got your eye right up next to it
[20:37:20] <Topy44> small amounts of reflected radiation should be harmless
[20:37:20] <SpeedEvil> Simply as the eye is completely opaque
[20:37:20] <LeelooMinai> Isn't that how you test those?
[20:37:21] <Topy44> still
[20:37:36] <SpeedEvil> The only issue is thermal damage on the surface of the eye
[20:37:43] <Topy44> we use some IR-opaque polycarbonate as loading door, works fine
[20:37:46] <SpeedEvil> it's orders of magnitude safer than a visible laser
[20:38:07] <SpeedEvil> more importantly
[20:38:08] <Topy44> SpeedEvil: if it was even close to focused the thermal damage would be enough though
[20:38:32] <Aero-Tec> error was cleared already
[20:38:37] <SpeedEvil> The shielding around the laser keeps the cuttting fumes in
[20:38:43] <SpeedEvil> and lets you vent them properly
[20:38:47] <Topy44> well yeah, that too
[20:38:49] <Aero-Tec> I can run some more and see when it errors again
[20:38:49] <SpeedEvil> they are far more dangerousingeneral
[20:38:55] <LeelooMinai> How bad cooking the surface of an eyball can be:)
[20:39:03] <Topy44> but you can also get reflections which can be pretty dangerous
[20:39:11] <Topy44> like if you hit some metal
[20:39:18] <SpeedEvil> Topy44: reflections of a beam that's gone through a lens aren't an issue
[20:39:25] <SpeedEvil> as they cannot be other than diverging
[20:39:29] <Topy44> hm, true
[20:39:47] <SpeedEvil> If something gets into your beam path prior to the lens - then in principle - sure
[20:39:52] <Topy44> but still. you don't want invisible high power lasers without proper enclosure. you just dont. :)
[20:40:11] <Topy44> well yeah, as is obvious by the paper we use to calibrate it
[20:40:11] <LeelooMinai> SpeedEvil: I am not current with it - are there any viable laser diodes that could cut stuff like acrylic yet?
[20:40:17] <Topy44> it...instantly vaporizes
[20:41:06] <Topy44> LeelooMinai: well one problem is that the affordable higher power laser diodes are usually near-UV/blue
[20:41:17] <Topy44> and acrylic is transparent to that
[20:41:47] <LeelooMinai> Hmm, so the best spectrum is what - infrared?
[20:41:52] <Topy44> as we found out in an attempt to calibrate a different device based on a 2W near-UV laser, which instead engraved the wood under it :)
[20:41:59] <Aero-Tec> BTW the test code machine has never erred and has run sim run a fair amount
[20:42:02] <SpeedEvil> Topy44: :)
[20:42:34] <Topy44> that was an interesting experience and one of those "oh. yeah. could have thought of that." moment :)
[20:42:39] <Topy44> *moments
[20:42:55] <Topy44> yeah, IR works best
[20:42:59] <LeelooMinai> I thought glass blocks UV mostly though
[20:43:07] <Topy44> depends on the glass
[20:43:09] <LeelooMinai> I guess acrylic is different
[20:43:42] <SpeedEvil> 'near UV' is the key
[20:43:46] <LeelooMinai> ANd they don't make IR laser diodes?
[20:43:46] <SpeedEvil> it's actually just violet
[20:43:51] <SpeedEvil> LeelooMinai: they do
[20:43:55] <SpeedEvil> but they're near-visible
[20:44:05] <SpeedEvil> ~800nm or 900nm tops for power ones
[20:44:17] <Topy44> they are actually very visible :) but most of the power is just outside the visible spectrum
[20:44:18] <LeelooMinai> And that's not low enough, right?
[20:44:22] <SpeedEvil> you can get 10um LEDs - but they suck really hard
[20:44:31] <Topy44> but they still paint the entire room in a very bright blue :)
[20:44:40] <SpeedEvil> Topy44: 808nm is almost exactly a million times dimmer than green
[20:44:53] <Topy44> right
[20:45:14] <SpeedEvil> 1mW/m^2 of 808nm beam is quite visible
[20:45:19] <SpeedEvil> if you look into it
[20:45:58] <Topy44> there are plenty of projects out there btw based on near-UV lasers
[20:46:10] <SpeedEvil> yeah
[20:46:14] <Topy44> a 2W one can cut paper, very thin wood, ...
[20:46:18] <Topy44> but its not really all that interesting
[20:46:38] <_methods> unless you hit the right person with it lol
[20:46:38] <LeelooMinai> I wonder if colored actylic would make any difference
[20:46:58] <Topy44> LeelooMinai: depends on the colour i guess :) might be worth a try
[20:47:06] <Topy44> but pure power is also an issue
[20:47:49] <Topy44> our 60W tube can cut 6mm acrylic well and 8-10mm ok-ish, though the optics are more of an issue than power
[20:48:13] <Topy44> but even 6mm wood or acrylic has to be cut pretty slowly
[20:49:13] <Topy44> i don't know the absorption specs for the various materials, but i would guess that you would need to go veeery slow with a 2W diode, and at that point you would be transferring so much heat to the surrounding material that you are lighting a fire instead of cutting :)
[20:49:14] <Aero-Tec> do you use air assist?
[20:49:18] <Topy44> yes
[20:49:28] <Topy44> well, sort of. its mostly just there to keep the fumes away from the lens
[20:49:42] <Aero-Tec> does upping the air jet power help much?
[20:49:44] <Topy44> i wanted to experiment with various types of gas and such
[20:49:58] <Topy44> don't know, its currently unregulated, just an airbrush compressor
[20:50:06] <Topy44> i'll have to do some experiments with that
[20:50:24] <Topy44> hook up the big compressor and see what influence it has
[20:50:50] <Aero-Tec> they cut metal using a air jet I believe
[20:51:00] <Topy44> yeah but not with a co2 glass tube
[20:51:13] <Topy44> you need a pulsed laser or a lot more power for that
[20:51:26] <Aero-Tec> as far as I know they use that
[20:51:26] <LeelooMinai> What do people use for cnc machining here in terms of air (for cooling, removing chips, etc.) I have normal compressor but it's noisy as hell... probably not the best choice.
[20:51:32] <Topy44> its also currently out of order because we need to rebuild the exhaust system, neighbours complained
[20:52:01] <Topy44> any advice on good and cheap filters is welcomed :) we need to get rid of the smell mostly
[20:52:09] <Topy44> noise is also an issue, but that one is more...controllable
[20:52:34] <Topy44> it will probably have to be some activated charcoal system, but that stuff is expensive...
[20:52:43] <Aero-Tec> bubble through water
[20:52:45] <Topy44> since we need large amounts of it for that kind of air throughput
[20:52:57] <Topy44> we thought about that, actually had a prototype system running once
[20:53:03] <Topy44> but didn't really work well
[20:53:06] <LeelooMinai> I saw some guy building a compressor from old fridge one and some tank, but it was too invvolved to be worth doing imho.
[20:53:49] <LeelooMinai> Since fridges have compressors that are pretty quiet
[20:53:55] <Topy44> well fridge compressors are quiet and suitable for long runtimes, but yeah, its essentially like an airbrush compressor
[20:54:08] <Topy44> you don't get very much throughput
[20:54:27] <Aero-Tec> I would run a shop vac and a bubble tank
[20:54:54] <Topy44> we might revisit the water system at some point
[20:55:11] <Aero-Tec> for the exhaust
[20:55:13] <Topy44> but its actually quite a lot of effort to build
[20:56:19] <Aero-Tec> not really
[20:56:46] <Topy44> well our fan is quite a bit larger than a shopvac :)
[20:56:58] <Topy44> its actually a blower for a bouncy castle :)
[20:57:08] <Aero-Tec> I made one using plexy and drilled a whack of holes
[20:57:39] <Aero-Tec> double bottom
[20:57:56] <Topy44> also one more issue
[20:58:24] <Topy44> our exhaust fan is mounted to the ceiling, directly at the wall where the chimney is installed that we blow the exhaust out
[20:58:27] <Aero-Tec> sir bubbles through the top bottom plate with all the holes
[20:59:06] <Topy44> we'd have to change that construction quite a bit because the water system would have to be mounted after the fan
[20:59:08] <Aero-Tec> air
[20:59:57] <Topy44> pretty sure the fan wouldn't appreciate water ending up in it
[21:00:01] <Aero-Tec> you do not have a encloser right?
[21:00:07] <Topy44> hm?
[21:00:11] <Aero-Tec> your right
[21:00:37] <Topy44> of course, the fan sits in a box
[21:00:52] <Aero-Tec> not fan, laser cutter
[21:00:59] <Topy44> and the laser is in a metal enclosure
[21:02:24] <Aero-Tec> can one not connect shop vac to enclosure and vent up chimney?
[21:02:46] <Aero-Tec> would get it higher and may stop the complaints
[21:02:54] <Topy44> nowhere near enough power :)
[21:03:06] <Topy44> ah, rather important point:
[21:03:26] <Topy44> the fan and chimney are about 50m away from the laser
[21:03:32] <Aero-Tec> how much air do you need to move?
[21:03:39] <Topy44> and the chimney goes up another 10m or so
[21:04:29] <Aero-Tec> just thinking if your vent is high enough the smell may not be bad lower down
[21:04:36] <Topy44> well
[21:04:40] <Topy44> we are in a basement
[21:04:50] <Topy44> and we are surrounded by 4-story residential buildings
[21:04:58] <Topy44> we can't go up _that_ far :)
[21:05:06] <Aero-Tec> ok
[21:05:15] <Aero-Tec> not your building?
[21:05:20] <Topy44> no
[21:05:22] <Aero-Tec> renting?
[21:05:25] <Topy44> we are a hackerspace. :)
[21:05:28] <Topy44> yeah
[21:05:42] <Topy44> and we are in an extremely expensive region
[21:06:11] <Topy44> we got a really good deal on this place, otherwise it would be completely unrealistic to have this much space (we have about 500m²)
[21:06:32] <Aero-Tec> so why would not a good size shop vac not move enough air and have enough head pressure to bubble though water?
[21:06:42] <zeeshan-s> man
[21:06:47] <Topy44> mostly because of the 50m of tubing
[21:06:48] <zeeshan-s> the lisle grinder is a saver
[21:07:02] <Topy44> i don't know how much throughput we actually need
[21:07:14] <Topy44> the blower we use now has more than we need
[21:07:22] <Topy44> but i mean... that thing is massive
[21:07:26] <Topy44> and its not _that_ much more than we need
[21:08:41] <Aero-Tec> if your dumping the laser fumes to the hack space and then venting through the room then yes you need a big fan
[21:09:08] <Topy44> its connected with 20cm steel tubing and runs all across the shop (other devices will be hooked up to it later, like the welding corner)
[21:09:44] <Topy44> Aero-Tec: no, of course not :)
[21:10:00] <Topy44> we are in a basement, remember? :) that would be... nasty
[21:10:04] <Aero-Tec> but if your making a negative are pressure in the enclosure and venting the fumes in a more concentrated stream it should work
[21:10:49] <Topy44> i don't see what problem the shopvac is supposed to solve
[21:10:57] <Topy44> the blower we have works and is plenty powerful
[21:11:12] <Topy44> the issue is getting a filter system that works with the kind of throughput
[21:11:17] <Topy44> to get the smell down
[21:11:36] <Aero-Tec> all the shop vac does is makes it easier to vent though a bubbler to trap the fumes
[21:11:51] <Topy44> (it doesn't have to be "my neighbours can't smell i'm growing weed"-perfect, just so that neighbours in the surrounding buildings don't complain)
[21:12:02] <Topy44> how is it easier than with the existing system?
[21:15:36] <PetefromTn_> Newest prototype Steyr Picatinny rail is finished except for some more deburring... http://i.imgur.com/jF97fGE.jpg http://i.imgur.com/OzE1cTE.jpg
[21:16:17] <zeeshan-s> that looks so sexy!
[21:16:25] <PetefromTn_> thanks man
[21:16:27] <zeeshan-s> do you machine that in 3 setups?
[21:16:28] <Aero-Tec> was hoping that a low cost water filter would work for you is all
[21:16:34] <zeeshan-s> it looks complex :d
[21:16:45] <zeeshan-s> i mean 4 setups
[21:16:55] <Aero-Tec> help keep cost down
[21:17:12] <PetefromTn_> well actually it is machined to depth from the first side including pocketing and drilling and champfering
[21:17:27] <PetefromTn_> then it gets flipped over to remove the flashing that was held in the vise
[21:17:45] <PetefromTn_> then it is champfered on the second side in that same position
[21:18:03] <PetefromTn_> then I turn it upside down and cut the female dovetail and slot
[21:18:23] <PetefromTn_> finally it is turned over again and set at the appropriate drooped angle and faced off flat
[21:18:28] <zeeshan-s> nice man
[21:18:32] <zeeshan-s> total time?
[21:18:41] <PetefromTn_> Finally the Picatinny program is run cutting the top dovetail picatinny rail
[21:19:07] <Aero-Tec> what metal did you use?
[21:19:20] <Aero-Tec> looks good
[21:19:29] <PetefromTn_> actual machine time is about an hour and a half or so maybe two hours mostly because the female dovetail is cut manually right now.
[21:19:38] <zeeshan-s> good :)
[21:19:38] <PetefromTn_> 6061-T6
[21:20:01] <Aero-Tec> cool
[21:20:12] <Aero-Tec> I need to make some chips
[21:20:14] <Aero-Tec> later
[21:20:16] <PetefromTn_> it is cut from a hunk of 1"x2"x10.25" material
[21:20:35] <Aero-Tec> what mill are you using?
[21:20:55] <PetefromTn_> Cincinatti Arrow 500 Vertical Machining Center retrofit with LinuxCNC
[21:21:11] <Topy44> heh... guns are a bit of a weird thing for me: i really dislike them personally, but i really appreciate the craftsmanship people put into them :)
[21:21:28] <PetefromTn_> this is for a precision air rifle
[21:21:41] <PetefromTn_> for Field Target Competition
[21:21:56] <Aero-Tec> do you make them to sell them?
[21:21:57] <LeelooMinai> Ther are sports like Biathlon where guns are3 not sued to kill people:)
[21:22:14] <PetefromTn_> yeah
[21:22:24] <PetefromTn_> trying to heh
[21:22:26] <Aero-Tec> most guns are not used for that
[21:22:37] <zeeshan-s> LeelooMinai: Make your table yet?
[21:22:38] <zeeshan-s> :P
[21:22:44] <Topy44> not just metalwork, but also crazy wooden grips and case hardening and such...
[21:23:05] <Topy44> LeelooMinai: sure, i appreciate that
[21:23:19] <PetefromTn_> I cannot wait to get my CNC lathe working I have a LOT of airgun parts I want to make with it.
[21:23:29] <LeelooMinai> I try to source non-poluyester resin, so epoxy resin for some sane price first - no so easy in Canada apparently:/
[21:24:14] <Aero-Tec> I should be more clear, most guns are not used to kill people
[21:24:17] <Topy44> maybe car restoration supply stores? thats where i get mine
[21:24:45] <Aero-Tec> PetefromTn_, your a airgunner?
[21:25:10] <LeelooMinai> I could probably buy polyester one for a price that I could swallow, but they are sub-optimal from what I read, since they shrink when curing
[21:25:11] <Topy44> Aero-Tec: but all uses other than killing living things are essentially a byproduct. anyway, don't want to start a political discussion, and i am perfectly aware of the many other uses
[21:26:28] <Aero-Tec> I use mine as tree toppers
[21:26:32] <Topy44> haha
[21:26:53] <Aero-Tec> whacking off dead branches up high
[21:27:02] <Topy44> thats a...creative use :)
[21:27:43] <Aero-Tec> works very well
[21:27:45] <skunkworks> PetefromTn_: dad just powered up his mazak.. it seems to work..
[21:28:23] <Topy44> firing a gun outside of a gun range would probably get you jailed pretty quickly around here :)
[21:28:26] <Topy44> (that is: europe)
[21:29:06] <Topy44> (unless you are a licensed hunter of course or have some other legitimate use)
[21:29:25] <LeelooMinai> Or have licence to kill:)
[21:29:30] <Topy44> yeah :)
[21:29:56] <Aero-Tec> I live in Canada
[21:30:05] <Aero-Tec> and not in a city
[21:30:27] <Aero-Tec> I can shoot in my yard
[21:30:40] <Aero-Tec> and crown land
[21:30:53] <PetefromTn_> yeah I have been into precision airguns for almost 20 years and got my first air rifle when I was ten.
[21:31:11] <Aero-Tec> and other places with owners permission
[21:31:14] <PetefromTn_> skunkworks Awesome man.. glad to hear it.
[21:31:17] <Topy44> it is kind of funny that it is illegal to fire or even buy a gun without some pretty extensive licensing, but perfectly legal to buy... i dont know... lasers and stuff :)
[21:31:23] <Topy44> or fancy chemicals
[21:32:00] <SpeedEvil> It is exceptionally hard to kill someone with a laser
[21:32:05] <Topy44> yeah, true
[21:32:06] <skunkworks> color screen and everything!
[21:32:28] <SpeedEvil> Unless it's big enough to kill them if it falls on them
[21:32:30] <Aero-Tec> I have a license so I am good to go
[21:32:34] <Topy44> go for the bond-version and very, very slowly slice someone in half, but not before leaving the room and going sure they have a means of escape!
[21:32:42] <PetefromTn_> nice
[21:32:58] <PetefromTn_> color me jealous
[21:33:11] <Topy44> _anyway_, i wanted to got to bed hours ago
[21:33:12] <PetefromTn_> That machine WILL make you money man Mazak Lathes are excellent iron
[21:33:14] <skunkworks> PetefromTn_: well - it is from 85'...
[21:33:31] <skunkworks> it looks very nicely built.
[21:33:32] <Topy44> our mill is from the early 70s :)
[21:33:41] <Topy44> proper oldschool german machinery though, weighs over a ton
[21:33:50] <PetefromTn_> yeah unless it is wore the hell out and even then it will still probably make accurate parts LOL
[21:33:59] <Topy44> not a hint of slack or vibration anywhere in it
[21:34:11] <skunkworks> Topy44: our cnc* is from the 60's.. (it started ist life as nc)
[21:34:35] <Topy44> nice
[21:34:38] <Topy44> i love old machinery
[21:35:09] <skunkworks> Topy44: http://electronicsam.com/images/KandT/oldkandt.JPG
[21:35:14] <skunkworks> still making parts
[21:35:29] <Topy44> wow, that looks very fancy
[21:35:41] <Topy44> we have a deckel fp2
[21:35:49] <Topy44> http://www.practicalmachinist.com/vb/attachments/f14/51255d1335819069-1954-deckel-fp2-dsc03318.jpg
[21:35:49] <PetefromTn_> skunkworks Did you see my new prototype rail I just posted? check it out LOL
[21:35:51] <Topy44> one of those
[21:35:52] <skunkworks> I hear those are very nice..
[21:36:14] <jdh> looks sweet
[21:36:35] <Topy44> its brutally overengineered, like all that old machinery, but i like it :)
[21:36:36] <skunkworks> PetefromTn_: Nice work!
[21:37:00] <Topy44> every single part of it, even if its not structurally relevant, is made from cast iron or huge hunks of steel
[21:37:23] <Topy44> it was "fun" getting that thing into the basement :)
[21:37:41] <Topy44> even disassembled some parts still weigh around 300kg
[21:37:44] <SpeedEvil> Was 'crashed through the floor' part of any report into the issue?
[21:37:52] <Topy44> heh
[21:38:03] <Topy44> actually we moved in before we signed the rental contract
[21:38:04] <skunkworks> The K&T is mostly weldments and some casting.
[21:38:22] <Topy44> and we said that if it drops we'll just claim that there already was a crater in the floor when we arrived :)
[21:38:25] <PetefromTn_> really thats interesting
[21:38:32] <jdh> http://raleigh.craigslist.org/tls/4772536325.html
[21:38:37] <PetefromTn_> that is how my Cincinatti is constructed
[21:38:56] <PetefromTn_> jdh Yeah I saw that posted it yesterday
[21:39:00] <PetefromTn_> neat little lathe
[21:39:06] <skunkworks> http://electronicsam.com/images/KandT/conversion/boxframe.JPG
[21:39:21] <Topy44> we actually own a proper big old lathe, but we can't get it into our place... its too heavy and too large
[21:39:46] <Topy44> weighs around a ton, and doesn't really come apart
[21:40:31] <Topy44> don't remember the model, but its also an old german thing from the 70s or so
[21:43:25] <Tom_L> skunkworks do you still have pics of the fest here?
[21:45:27] <skunkworks> Tom_L: these? http://electronicsam.com/images/KandT/Fest2013/
[21:45:49] <Tom_L> yep
[21:45:50] <Tom_L> thanks
[21:45:52] <skunkworks> sorry they are not labled..
[21:49:49] <skunkworks> most would be labled - guys standing around.
[21:54:32] <jdh> other guys standing around
[21:54:36] <jdh> some more guys
[21:54:42] <jdh> hot linuxcnc chick standing around
[22:01:59] <jfigie> I have my SEM motor off the machine but still connected. I have removed the cover on the position encoder. I want to get to the tach. Does anyone have experience with this kind of motor? https://drive.google.com/file/d/0B2fj8HWg0FnNS19LN3hPaS1WeDg/view?usp=sharing
[22:03:30] <jfigie> here is there is the whole motor https://drive.google.com/file/d/0B2fj8HWg0FnNejA4LWEtb1VRREU/view?usp=sharing
[22:04:04] <Topy44> by the way, does linuxcnc support closed loop servo-systems?
[22:04:11] <jdh> yes
[22:04:51] <Topy44> i have been thinking about building a large-ish 3d printer using servos instead of stepper motors
[22:05:37] <jdh> for the mass and forces on a 3d printer, I would question if there is any real benefit for servos
[22:05:43] <Topy44> but grbl, the motor control library used by all 3d printer firmwares that i know of does not support closed loop systems (and can't easily be modified to do so)
[22:06:14] <Topy44> well, one thing with servos is that you don't have to give them full power all the time
[22:06:39] <Topy44> its relative to acceleration
[22:06:53] <jdh> smarter stepper drivers will reduce stepper current
[22:07:04] <Topy44> hm, i should check those out
[22:07:18] <jdh> when idle
[23:14:15] <PetefromTn_> Getting ready to cut this Edge lit sign hopefully over the holiday weekend.
[23:14:48] <PetefromTn_> planning to cut it with carpet tape on top of a sacrificial substrate
[23:15:00] <XXCoder> PetefromTn_: good luck!
[23:15:03] <PetefromTn_> this stuff is 3/8 thick
[23:15:06] <XXCoder> do a air cut first
[23:15:20] <PetefromTn_> any recommendations for feeds and speeds on it.
[23:15:31] <zeeshan|2> what matl?
[23:15:41] <PetefromTn_> thanks for the tip but I don't really need to do air cuts with this project
[23:15:54] <PetefromTn_> it's Extruded clear Acrylic sheet
[23:16:01] <XXCoder> yea im pretty sure youre more expert than me. I was kidding
[23:16:01] <zeeshan|2> hehe
[23:16:02] <zeeshan|2> HEHE
[23:16:25] <zeeshan|2> did you buy the material already?
[23:16:32] <zeeshan|2> polycarbonate!!
[23:16:32] <PetefromTn_> it's already here
[23:16:34] <Connor> what type of endmill ?
[23:16:38] <zeeshan|2> aw
[23:16:51] <Connor> and diameter ?
[23:16:51] <PetefromTn_> just a 3/8 four flute HSS probably
[23:17:10] <Topy44> zeeshan|2: i once tried with carpet tape, it didn't stick properly, started moving after a while because of the vibration
[23:17:39] <Topy44> also, you might need cooling so it doesn
[23:17:42] <XXCoder> wonder if screws at areas that will be cut off would help for most of decocations cut
[23:17:43] <zeeshan|2> well depends on cutting forces
[23:17:44] <PetefromTn_> actually I have used Carpet tape numerous times without issues for this
[23:17:47] <XXCoder> then finally just cut it out?
[23:17:52] <zeeshan|2> if youre going too rough
[23:17:57] <zeeshan|2> it wont work :P
[23:18:01] <Topy44> the acrylic tends to melt
[23:18:17] <Connor> 5299 RPM @ 93.48 ipm
[23:18:28] <zeeshan|2> yea i wouldnt be going 93 ipm
[23:18:31] <zeeshan|2> on carpet tape
[23:18:32] <zeeshan|2> :)
[23:18:43] <PetefromTn_> The lsat time I did this I made multiple depths passes at like .125 deep leaving a finish pass of .01
[23:19:07] <PetefromTn_> then once at depth made the finish pass
[23:19:09] <renesis> topy44: i use soapy water to cut acrylic =\
[23:19:15] <Topy44> yeah, that works great
[23:19:20] <Topy44> thats what i used
[23:19:40] <Connor> @ .125 DOC, 140.22 IPM
[23:19:43] <renesis> i jigsawed some yesterday, after making the cuts i still had to plastic hammer the chunk off
[23:19:48] <Connor> http://zero-divide.net/?page=fswizard
[23:19:51] <renesis> plastic welded behind the cut
[23:19:54] <Topy44> i dont have all that much experience with acrylic though because we then built our laser cutter
[23:19:57] <renesis> stupid 1" acrylic
[23:20:17] <Topy44> heh, yeah, that happens
[23:20:55] <PetefromTn_> I have already made several of these just did not get the LED setups finished but this is much thicker material
[23:21:09] <renesis> machining, i do high feed low speed and dont always need to lube
[23:21:33] <Topy44> yeah, low spindle speed and high feedrate
[23:21:36] <PetefromTn_> It is a gift for my wife so I want it to be as perfect as possible.
[23:21:45] <zeeshan|2> yea but you also gotta remember how youre holding it
[23:21:52] <zeeshan|2> so your calculated feed isnt always optimal
[23:21:56] <LeelooMinai> Since I cannot find well-prices epoxy resin, I wondere if I could use this instead: http://www.custombuildingproducts.com/TDS/TDS-101.pdf
[23:22:01] <renesis> using the soapy water machining makes nasty mess =( the dry chips are way easier to clean
[23:22:12] <Topy44> you can polish it quite nicely on a cotton disk with any fine polishing wax or such
[23:22:18] <LeelooMinai> Not sure what it is exactly, but it may be epoxy resin with some fillter
[23:22:25] <Topy44> acrylic polishes very nicely
[23:22:30] <renesis> ya
[23:22:31] <PetefromTn_> if I am going to use coolant I will just turn on the flood coolant I guess
[23:22:46] <LeelooMinai> They shrinkage they list there is minimal, so it may not be polyester one, I think
[23:22:47] <XXCoder> HMMM ssi http://geekologie.com/2014/11/tis-the-season-laser-etching-a-pumpkin-p.php
[23:22:59] <Tom_L> PetefromTn_ use air or mist
[23:23:06] <PetefromTn_> why?
[23:23:11] <Tom_L> 2 flute won't gum up as much either
[23:23:24] <LeelooMinai> I wonder if I mixed it with granite pebbles, if I would get reasonable epoxy/granite mix - any opinions?
[23:23:36] <Tom_L> to keep the cutter cool
[23:23:37] <PetefromTn_> I may just screw around with a piece of drop
[23:23:44] <Tom_L> and keep the plastic from melting around it
[23:23:49] <PetefromTn_> over flood coolant?
[23:23:54] <renesis> yeah its like cutting aluminum, but much worse
[23:23:57] <Tom_L> black is much much worse than clear
[23:24:01] <Connor> With a 2 flute.. the feed rate drips to 72.79 IPM and the torque drops down too.
[23:24:04] <renesis> why you have to feed fast
[23:24:25] <renesis> if you spend to much time in one spot shit turns to goo
[23:24:28] <Topy44> acrylic is evil stuff
[23:24:34] <zeeshan|2> PetefromTn_: cheapie
[23:24:37] <Tom_L> you need very sharp tools
[23:24:38] <PetefromTn_> I was gonna feed that four flute at like 4500 at maybe 40-50 IPM
[23:24:38] <renesis> looks great, tho
[23:24:41] <Topy44> yeah
[23:24:47] <Topy44> and on the laser cutter its great
[23:24:48] <zeeshan|2> give her a titanium sculpture !
[23:24:51] <renesis> carbide is great for acrylic, doesnt dull
[23:24:53] <Topy44> but i don't want to mill it ever again :)
[23:24:56] <renesis> so you just have to manage temps
[23:25:01] <Tom_L> i use carbide on it for sure
[23:25:11] <Connor> PetefromTn_: FSWizard is saying 5300 rpm, 130 IPM
[23:25:29] <Connor> for 4 flute, 5300 RPM, 73 IPM
[23:25:31] <renesis> for pockets sometimes i would just fill with water and let it machine submerge
[23:25:34] <PetefromTn_> that sounds very high feed to me man.
[23:25:35] <Connor> for a 2 flute
[23:25:42] <renesis> recutting acrylic doesnt do anything to the tool
[23:25:54] <PetefromTn_> sure
[23:25:56] <XXCoder> zeeshan|2: tungesin ;)
[23:26:01] <renesis> and once enough chips it doesnt just fly out
[23:26:04] <XXCoder> I bet that's hell on any cnc
[23:26:11] <PetefromTn_> zeeshan|2 Hey man it is what she wanted..
[23:26:21] <zeeshan|2> hehe im teasing :p
[23:26:31] <PetefromTn_> she is a HUGE Alice in Chains fan
[23:26:37] <renesis> neat
[23:26:43] <PetefromTn_> so she wanted something I made with AIC on it.
[23:26:48] <zeeshan|2> nicer
[23:26:55] <PetefromTn_> did I show you the engraving .dxf?
[23:27:14] <zeeshan|2> no
[23:27:18] <zeeshan|2> lets see
[23:27:21] <PetefromTn_> wanna see it?
[23:28:24] <PetefromTn_> http://i.imgur.com/cw904nZ.jpg
[23:28:33] <zeeshan|2> :D
[23:28:37] <zeeshan|2> that looks awesome!!
[23:28:45] <zeeshan|2> did you design that?
[23:28:53] <PetefromTn_> well technically no
[23:29:03] <PetefromTn_> I downloaded a pic of their logo which is similar
[23:29:11] <PetefromTn_> then I imported it into my autocad clone
[23:29:15] <PetefromTn_> and kinda traced it out.
[23:29:21] <zeeshan|2> looks really good :)
[23:29:22] <PetefromTn_> Then I realized that thier logo sucked
[23:29:29] <PetefromTn_> so I kinda fixed it
[23:29:35] <PetefromTn_> and added some other details
[23:29:39] <PetefromTn_> thanks
[23:29:44] <zeeshan|2> im gooogling it
[23:29:51] <zeeshan|2> yours looks different :)
[23:29:53] <PetefromTn_> she seemed to like it so I hope I can make it look sweet
[23:30:10] <PetefromTn_> yeah there are actually several different versions of that logo
[23:30:20] <PetefromTn_> I traced from the all white and black one
[23:33:25] <PetefromTn_> http://hdwallpapersbase.com/wp-content/uploads/2013/06/Alice-In-Chains-logo-wallpaper.jpg
[23:33:38] <PetefromTn_> I thought about adding that logo underneath the sun logo
[23:33:56] <PetefromTn_> but when I looked at it I think it would be a real bitch to trace over.
[23:34:08] <PetefromTn_> so I guess I am lazy LOL
[23:39:51] <zeeshan|2> do it!
[23:39:55] <zeeshan|2> that will look bad ass
[23:40:04] <zeeshan|2> maybe you can use splines?
[23:40:12] <zeeshan|2> yea i think you can do that with splines
[23:40:13] <PetefromTn_> I did use splines
[23:40:26] <zeeshan|2> looks like 20 min of tracing
[23:40:26] <zeeshan|2> haha
[23:40:28] <PetefromTn_> but those shapes are a real bitch I think
[23:40:43] <PetefromTn_> Shit maybe 2 hours LOL
[23:40:47] <zeeshan|2> haha
[23:40:52] <zeeshan|2> she's worth it!
[23:40:53] <zeeshan|2> DO IT!! :P
[23:40:58] <PetefromTn_> Damn right she is
[23:41:13] <PetefromTn_> anyone who could put up with my bullshit is worth it heh
[23:41:14] <zeeshan|2> my significant others bday is on dec 1
[23:41:17] <zeeshan|2> i gotta figure out a present :/
[23:41:25] <zeeshan|2> my cnc mill doesnt run :{
[23:41:58] <PetefromTn_> she got the idea from another AIC fan
[23:42:14] <PetefromTn_> apparently this guys wife has a CNC plasma cutter
[23:42:28] <PetefromTn_> and he made some steel plate yard art with thier logos on it.
[23:42:35] <PetefromTn_> looked pretty cool actually
[23:43:16] <Connor> PetefromTn_: http://www.engraverssolutions.com/PDFs/tips&tricks-routing_acrylic.pdf
[23:44:20] <XXCoder> man I need to complete my cnc
[23:44:25] <XXCoder> so I can have fun
[23:46:25] <PetefromTn_> jeez according to that you want to run really high speed spindle and relatively slow feeds considering the spindle speed
[23:51:22] <XXCoder> probably some coolant to keep plastic cool
