[00:00:13] <PetefromTn_> Freakin' thing NEVER connects even sometimes after I reset the wireless router with my laptop...ANNOYING!!
[00:00:43] <PetefromTn_> It is the only damn thing in the whole house full of interconnected wireless crap that does not...
[00:01:09] <PetefromTn_> This is the second one we got and tried too. Took the first one back because of the same issue.
[00:01:25] <ssi> I've never owned a standalone bluray player
[00:01:30] <ssi> always just used the ps3 for that
[00:01:36] <PetefromTn_> we do that too...
[00:02:03] <PetefromTn_> use this thing to watch netflix and youtube stuff aside from watching movies on blu ray.
[00:02:07] <ssi> gotcha
[00:02:10] <ssi> I use appletv for that
[00:02:14] <ssi> but ps3 can do it too
[00:02:24] <PetefromTn_> yeah I know..
[00:02:26] <ssi> everything does netflix these days :P
[00:02:32] <ssi> hell most new tvs even do it
[00:02:35] <ssi> nuts
[00:02:37] <PetefromTn_> everything but this POS.
[00:02:40] <ssi> ehehe
[00:02:58] <PetefromTn_> my TV does it as well..but we are loathe to run the damn cable again under the house.
[00:03:27] <ssi> yea
[00:03:35] <PetefromTn_> My wife decided she wanted to rearrange the room again and now the big flatscreen is on the other side..
[00:03:59] <ssi> lol comcast is advertising 505mbit internet here now
[00:04:01] <ssi> $399/mo
[00:04:03] <PetefromTn_> I guess I am gonna have to break down and crawl under there. Was hoping this POS would just work wirelessly but whatyagonnado....
[00:04:15] <PetefromTn_> GASP!!
[00:04:22] <ssi> sorry, $399.95
[00:04:24] <ssi> :P
[00:04:29] <ssi> I wonder if it still has a 300GB/mo cap
[00:04:34] <PetefromTn_> STILL GASPING>..
[00:04:37] <ssi> I have the 105mbit now, and it has the same 300GB/mo cap
[00:04:39] <ssi> ridiculous
[00:04:46] <ssi> oh man it gets better
[00:04:54] <ssi> $400/mo and you have to sign a THREE YEAR CONTRACT
[00:05:27] <PetefromTn_> We have Charter high speed and it actually is perfect... We do not have the highest speed tier just the second highest.
[00:05:54] <PetefromTn_> For $400 a month I better get a geisha and a masseuse with it...
[00:05:59] <ssi> srsly
[00:06:33] <PetefromTn_> must be all those rich folks in Hotlanta driving the prices up or something LOL..
[00:08:09] <PetefromTn_> Perhaps tomorrow I will tunnel under and hookup the cable finally. I am so over this POS...
[00:08:22] <ssi> whoa chattanooga has municipal gigabit fiber service for $70/mo
[00:08:25] <ssi> provided by the electric company
[00:08:29] <ssi> that's pretty awesome
[00:08:32] <ssi> almost awesome enough to move there
[00:08:37] <ssi> it'd add 70 miles to my commute :P
[00:08:46] <PetefromTn_> hell fly to work man...
[00:09:01] <ssi> you know, I always wanted to build a helicycle and see if they'd let me land it on the parking deck
[00:09:05] <PetefromTn_> then you can move here, buy my house and my CNC and be happy LO...
[00:09:12] <ssi> hahahah
[00:09:14] <Jymmm> 1Gbps up and down
[00:09:53] <PetefromTn_> My wife is off all next week and we are gonna finish our damn kitchen finally or at least that is the plan.
[00:10:34] <ssi> Jymmm: yaaaa
[00:10:36] <ssi> " In Chattanooga TN, the public utility provides 1 gigabit/sec download & 1 gigabit/sec upload speeds for $70 a month, which is $20 a month less than I'm paying my broadband monopoly (Comcast) for 1/20th the download speed and 1/100th the upload speed as Chattanooga's municipal network."
[00:10:50] <ssi> fiber to the home is awesome
[00:12:17] <Jymmm> Not available here (yet)
[00:12:40] <ssi> I was actually surprised at how much the internet available in the bay area is NOT great
[00:13:10] <Jymmm> It depends on where you are, lots of OLD copper
[00:13:22] <PetefromTn_> I think mine is like 30 or 40 MBPS or something like that.
[00:13:42] <ssi> mine clocks speedtest at 122
[00:14:03] <Jymmm> you guys must be on cable
[00:14:10] <ssi> yep
[00:14:23] <PetefromTn_> they are always talking about how fast they are and how great a value it is...perhaps they are full of shite..
[00:14:27] <ssi> cable and fiber are the only options these days :P
[00:14:30] <PetefromTn_> yeah cable
[00:14:32] <ssi> dsl got left behind long ago
[00:14:47] <Jymmm> Well, ADSL did, there is VDSL now.
[00:14:55] <PetefromTn_> I don't even think I know anyone with DSL anymore.
[00:15:05] <Jymmm> I have VDSL
[00:15:13] <ssi> what sort of speeds do you see
[00:15:14] <Jymmm> I used to have ADSL long ago
[00:15:21] <PetefromTn_> venereal disease speedy light..?
[00:15:35] <Jymmm> I have 18/1 unshared, unlike you guys.
[00:15:52] <ssi> not terrible, but not great
[00:16:08] <Jymmm> In certain ways I'd prefer ADSL, the latency was MUCH less.
[00:16:08] <ssi> the shared loop thing really hasn't been an issue in my experience
[00:16:12] <ssi> ew
[00:16:15] <ssi> I hate latency
[00:16:22] <ssi> poor JT is on satellite
[00:16:31] <Jymmm> you must be a fscking gamer! lol
[00:16:36] <ssi> no, not a gamer
[00:16:39] <ssi> I just don't like latency
[00:16:47] <Jymmm> ah
[00:16:53] <ssi> I have to do a lot of remote shell work
[00:16:54] <PetefromTn_> I used to have satellite when we lived out in dah woods...
[00:16:57] <ssi> and I hate waiting for my keystrokes
[00:17:02] <Jymmm> Yeah, JT-Shop has the suck end of things. Poor bastard.
[00:17:04] <ssi> in fact this irc session is in a remote shell
[00:17:24] <ssi> over vpn no less :P
[00:17:29] <PetefromTn_> is it a conch shell?
[00:17:40] <ssi> yeah... every time I talk to you guys I can hear the ocean ;)
[00:17:43] <Jymmm> ssi: yeah yeah big woop
[00:17:45] <PetefromTn_> I love Conch Fritters man..LOVE EM'
[00:18:49] <PetefromTn_> Drove all the way to gatlinburg this weekend to try out a Cajun place called Crawdaddys because they had it on their online menu....Got there....NO FREAKIN' Conch Fritters.. BASTARDS!!!!
[00:19:02] <ssi> aww
[00:19:11] <ssi> i flew into sevierville a few times
[00:19:34] <PetefromTn_> They did have some delicious Gator Tails and some excellent mussels with andoille sausage..
[00:19:48] <PetefromTn_> WHAT and you did not let me know??!!
[00:19:56] <ssi> haha it was years ago
[00:20:58] <PetefromTn_> The calamari was good but a bit firm for my tastes.
[00:21:10] <PetefromTn_> I must be hungry er somethin'...
[00:21:26] <ssi> I snuck out earlier and had a gyro :)
[00:21:34] <PetefromTn_> Ooh I love Gyros..
[00:21:52] <ssi> we have a great 24h greek diner in marietta
[00:21:55] <PetefromTn_> We have a little delicatessen here that serves fresh Gyros..
[00:22:47] <PetefromTn_> Ya know I bought my wife's SUV from a place in northern Atlanta that had a nice Greek diner...we ate there while they installed a brand new windshield in her car...
[00:23:05] <ssi> in town? might have been landmark diner
[00:23:07] <PetefromTn_> Best damn Gyro I ever had really...
[00:23:15] <ssi> that's in buckhead
[00:23:21] <PetefromTn_> It was a bit north of town in a strip mall...
[00:23:26] <ssi> hm dunno
[00:23:36] <PetefromTn_> kinda off the big hwy that runs AROUND Atlanta...
[00:23:53] <ssi> that'd be 285
[00:23:59] <PetefromTn_> yup I think so..
[00:24:20] <PetefromTn_> it was off there the guy was a used car dealer working out of a buildings parking lot...
[00:24:34] <PetefromTn_> Got a good deal she loves her SUV..
[00:25:37] <ssi> :)
[00:26:17] <PetefromTn_> You still use your Lathe?
[00:26:24] <ssi> it's been down for ages
[00:26:29] <PetefromTn_> SOB...
[00:26:35] <ssi> as soon as the plasma table is fixed I'm gonna dive into the pneumatics
[00:26:40] <ssi> jt is gonna help me figure it out
[00:26:46] <ssi> trying to bribe him down here with beer and pizza and plane rides :)
[00:27:00] <PetefromTn_> That should work I think....
[00:27:06] <PetefromTn_> what is wrong with it?
[00:27:14] <ssi> the turret quit on me
[00:27:19] <PetefromTn_> SOB
[00:27:21] <ssi> I took it apart and found a broken shuttle valve
[00:27:26] <ssi> replaced it at great personal expens
[00:27:29] <ssi> was like $300 from hardinge
[00:27:36] <PetefromTn_> ouchie.
[00:27:37] <ssi> put it all back together and now it's worse
[00:27:51] <ssi> constant air leak, when you command a tool change it turns into a louder airleak
[00:27:53] <PetefromTn_> did you let the magic out er somethin'?
[00:27:55] <ssi> no motion
[00:27:57] <ssi> it's all pneumatics
[00:28:03] <ssi> and I'm stupid when it comes to pneumatics
[00:28:08] <PetefromTn_> pneumatic magic?
[00:28:14] <ssi> yea
[00:28:17] <ssi> I let the magic air out :)
[00:28:40] <PetefromTn_> Tell ya what, I will take that poor POS off your hands man.. You don't need the stress. You'll feel better.
[00:28:51] <ssi> trade ya for the cincy
[00:29:05] <PetefromTn_> Sorry man NEED the Cinci.
[00:29:07] <ssi> heheh
[00:29:15] <PetefromTn_> Need both damnit.
[00:29:17] <ssi> I'll give you a great price on it
[00:29:25] <PetefromTn_> Oh I am sure you will....
[00:29:32] <PetefromTn_> need a kidney?
[00:29:42] <ssi> I'd sell it for pretty cheap actually
[00:29:46] <ssi> just probably not all the tooling
[00:29:48] <PetefromTn_> how cheep?
[00:29:49] <ssi> I got raped on the tooling :)
[00:29:58] <PetefromTn_> I like cheeep.
[00:30:18] <ssi> maybe $3k with the computer and mesa gear and vfds and everything
[00:30:25] <ssi> and the 10 gallons of very expensive mobilmet in it :)
[00:30:46] <PetefromTn_> That is not bad really... Does everything else work?
[00:30:53] <ssi> yeah everything works great
[00:30:57] <ssi> it's a really super machine
[00:31:01] <ssi> once the turreet's running again :P
[00:31:06] <PetefromTn_> hows the spindle sound?
[00:31:10] <ssi> sounds fine
[00:31:17] <ssi> I've done some precision work on it
[00:31:20] <ssi> it'll hold tenths all day long
[00:31:28] <PetefromTn_> collets?
[00:31:42] <ssi> what about 'em? :)
[00:31:45] <PetefromTn_> Ya got a chuck for the monster?
[00:31:49] <ssi> I don't have a chuck
[00:31:55] <PetefromTn_> damn.
[00:32:02] <ssi> I've done bigger work in step collets
[00:32:09] <PetefromTn_> Whatsa 5c go up to?
[00:32:14] <ssi> 1-1/16
[00:32:29] <ssi> CHNC is 16C, which'd be a nice upgrade
[00:32:31] <ssi> 1-5/8
[00:32:43] <PetefromTn_> I got the 12x36 here that works for that larger stuff pretty good.
[00:33:03] <ssi> chucks for that spindle nose are out there, I jsut haven't managed to lay hands on one yet
[00:33:13] <PetefromTn_> Is it running 3 phase or single..?
[00:33:21] <ssi> takes single phase in
[00:33:27] <PetefromTn_> awesome.
[00:33:27] <ssi> have two VFDs in it
[00:33:33] <PetefromTn_> two?
[00:33:35] <ssi> 3hp for the spindle and a 1/4 for the coolant pump
[00:33:42] <PetefromTn_> aah just like my machine.
[00:33:55] <PetefromTn_> would be a perfect match for my mill really....
[00:33:58] <ssi> yeah
[00:34:06] <ssi> it's using the original drives and drive power supply
[00:34:13] <PetefromTn_> Oh that sucks..
[00:34:19] <ssi> they work
[00:34:31] <PetefromTn_> I know my original drives cost a MINT when they blew...
[00:34:40] <PetefromTn_> That is why I gutted the pig and went with new stuff..
[00:34:48] <ssi> I'd replace the drives with AMC drives if these went out
[00:35:01] <ssi> all the resolver work is figured out
[00:35:12] <ssi> pcw had to make me a special version of his resolver converter to do this machine
[00:35:23] <ssi> the resolvers are actually pretty nice
[00:35:25] <ssi> VERY high resolution
[00:35:36] <PetefromTn_> I almost bought a machine just like that a couple weeks ago that was in need of work.
[00:35:45] <PetefromTn_> it was like $1100.00...
[00:36:02] <ssi> yes they can be had cheap because nobody wants to deal with those tape fed controls
[00:36:02] <PetefromTn_> PCW is da man....
[00:37:00] <PetefromTn_> I don't have 3k right now but if you are not in a huge hurry I might be able to get it from you in awhile...
[00:37:13] <ssi> keep it in mind
[00:37:27] <ssi> I'm trying to unload machines so I can get out of this house
[00:37:31] <PetefromTn_> ya got any current pics of it? How are the ways..
[00:37:36] <ssi> ways are perfect
[00:37:43] <ssi> I replaced the big rubber wipers
[00:38:00] <ssi> when I got it, it had been sitting in one spot and the rubber rotted and kinda gunked up the way at the tail end
[00:38:08] <ssi> and there's some staining from that, but nothing that affects motion
[00:38:15] <ssi> those rubber bits were pretty expensive
[00:38:26] <PetefromTn_> isn't everything...
[00:38:26] <ssi> I had to replace a nickel bellows coupler on the X axis which was expensive
[00:38:37] <ssi> when I first tuned the axes, some high accel broke it
[00:38:49] <ssi> $88 for that little bastard
[00:39:07] <PetefromTn_> glad you can still get parts for it.
[00:39:12] <ssi> yep, from hardinge
[00:39:18] <ssi> good that you can get them
[00:39:22] <ssi> bad that you have to bust out the dollars
[00:39:26] <ssi> they are NOT cheap
[00:39:34] <PetefromTn_> bust out the wallet and weep...
[00:39:38] <CaptHindsight> anyone know a good fractional HP coolant pump for retrofits that will handle the occasional chip and sludge?
[00:40:39] <ssi> PetefromTn_: my plan is to get all this work done on the plasma table and really clean it up nice, get it working well, and see if I can sell it
[00:40:42] <ssi> then work on the HNC
[00:40:52] <PetefromTn_> good plan.
[00:40:54] <ssi> I can probably sell the little g0602 as a turnkey package
[00:41:01] <PetefromTn_> Wish I could afford to buy both from you...
[00:41:04] <ssi> the clausing's gotta go
[00:41:12] <ssi> it's a nice old lathe but the ways are very worn :(
[00:41:15] <PetefromTn_> don't want or need the hobby stuff.
[00:41:16] <ssi> so it'll probably go pretty cheap
[00:41:25] <ssi> and I have a reid 2C surface grinder that I can sell
[00:41:41] <ssi> once everything's gone I'll prolly sell my grizzly 7x12 bandsaw
[00:41:44] <ssi> which is a pretty nice saw
[00:41:45] <PetefromTn_> ya need 2 kidneys?
[00:41:51] <ssi> not yet :P
[00:42:00] <PetefromTn_> I already have a 7x12,,,love it.
[00:42:07] <ssi> yeah that was one of the best upgrades I made
[00:42:14] <ssi> moving up from hf 4x6
[00:42:20] <ssi> piece of junk
[00:42:21] <PetefromTn_> beats the shit outta the 4x6 huh...
[00:42:24] <ssi> yep
[00:42:38] <PetefromTn_> I use mine daily here..
[00:42:46] <ssi> yeah
[00:42:51] <ssi> ;i had to replace my blade recently
[00:42:53] <PetefromTn_> Right now the blade is tweaked a little but it still cuts so I have not swapped it.
[00:43:09] <ssi> I had the brilliant idea that I could cut two feet off a piece of 30mm profile rail with the bandsaw
[00:43:12] <PetefromTn_> Got caught in a piece of shit thin wallled pipe I cut for my neighbor..
[00:43:28] <ssi> made a dull spot on the rail and rubbed all the teeth off the blade :)
[00:43:36] <PetefromTn_> hard
[00:43:40] <ssi> yeah very hard
[00:43:51] <ssi> just one of those brainfart moments
[00:43:56] <ssi> cut it with the abrasive cutoff saw
[00:43:58] <ssi> HF special
[00:44:03] <PetefromTn_> mine came to me used with some nasty heavy cutting oil in it..
[00:44:08] <ssi> I bought mine new
[00:44:20] <ssi> when I went to get the hardinge, I pulled a trailer through harrisburg
[00:44:22] <PetefromTn_> I cleaned that sludge out and switched to the same stuff I use in the mill... works great.
[00:44:28] <ssi> and decided on spur of the moment to visit the griz showroom
[00:44:31] <ssi> and impulse bought a bandsaw
[00:44:32] <PetefromTn_> bought mine for $200.00
[00:44:36] <ssi> nice deal
[00:44:38] <ssi> I paid like $800 :P
[00:45:09] <PetefromTn_> thats about what they cost I think for the most part.
[00:45:12] <ssi> yep
[00:45:17] <ssi> I don't regret it
[00:45:23] <PetefromTn_> nope they work real good.
[00:45:31] <PetefromTn_> I have cut lots of stuff with it. All the time really.
[00:45:45] <PetefromTn_> I want to make a nice vertical setup for it but never get around to it.
[00:45:59] <ssi> I have a vertical bandsaw around
[00:46:01] <ssi> not a great one
[00:46:06] <ssi> but it keeps me from screwing with the horizontal
[00:46:12] <PetefromTn_> is it a metal cutting one?
[00:46:16] <ssi> no
[00:46:18] <ssi> but it can :)
[00:46:25] <ssi> mostly aluminum
[00:46:40] <PetefromTn_> yeah I know. I burnt the rubber wheels off my old wood cutting bandsaw and had to source new ones.
[00:46:50] <PetefromTn_> Trying to cut some sheetmetal.
[00:46:53] <PetefromTn_> It worked...sorta.
[00:47:11] <PetefromTn_> Cost me more to fix it than I wanted tho.
[00:47:39] <ssi> heheh
[00:47:47] <PetefromTn_> I did make a little metal plate that screws onto the guides for vertical stuff. It is just not near big enough.
[00:48:04] <PetefromTn_> Need to make something that has a leg that goes to the ground and clamps on somehow.
[00:48:15] <PetefromTn_> The saw is quite capable vertically actually...
[00:48:41] <PetefromTn_> Way better than my 4x6 even after I modded the piss out of it. I sold it when the second motor died on it.
[00:48:48] <ssi> heheh
[00:49:18] <PetefromTn_> would love a nice doall or similar vertical.
[00:49:28] <ssi> oh did I tell you about the punch press I got?
[00:49:32] <ssi> sorta got
[00:49:39] <PetefromTn_> jeez man you are starting to piss me off here..
[00:49:41] <ssi> haha
[00:49:49] <ssi> it's a diacro VT-19 turret punch
[00:49:54] <ssi> not a remarkably capacitous machine
[00:49:59] <ssi> like 19"x24" or something like that
[00:50:08] <ssi> has the same GE 550 control the HNC had
[00:50:10] <ssi> tape fed mess
[00:50:11] <PetefromTn_> nice..
[00:50:16] <ssi> I haven't done anything with it yet
[00:50:19] <ssi> I don't technically own it
[00:50:29] <ssi> this guy delivered it to my hangar and I have an arrangement
[00:50:33] <ssi> I'm storing it for free
[00:50:34] <PetefromTn_> oh one of those deals lOL
[00:50:42] <ssi> if I convert it, he owns $3k worth of whatever it ends up worth
[00:51:02] <ssi> it wouldn't be worth 3k, but he's got over 100 dies for it
[00:51:04] <ssi> so maybe it is
[00:51:20] <PetefromTn_> I gotta remember to send my 7i77 back to get repaired...keep forgettin.
[00:51:28] <ssi> what'd you do to it?!
[00:51:38] <PetefromTn_> smoked the shit out of it..
[00:51:58] <PetefromTn_> fried it like a thanksgiving turkey..
[00:52:04] <ssi> bad pete
[00:52:10] <PetefromTn_> yup...
[00:52:13] <ssi> haha I fried a 5i25, dunno if you saw that
[00:52:43] <PetefromTn_> but it is working again after a new set of relays, a new 24 volt power supply and a new 7i77 thankfully...
[00:52:47] <PetefromTn_> nope.
[00:53:05] <ssi> I switched the plasma table to use ohmic sensing instead of floating head
[00:53:18] <ssi> and neglected to provide a way to decouple that line from the io pin when the torch fires
[00:53:25] <ssi> so I fired the torch and put 400V or so into an io
[00:53:28] <PetefromTn_> doh!!
[00:53:36] <ssi> yuuuup
[00:53:58] <PetefromTn_> sounds like what I did... I put 220 volts into the 24 volt power supply!
[00:54:10] <ssi> :D
[00:54:11] <PetefromTn_> on the output LOL
[00:54:25] <ssi> yea so you actually smoked it huh
[00:54:29] <ssi> I didn't smoke the 5i25
[00:54:34] <ssi> I think I just killed one of the bus switch chips
[00:54:37] <PetefromTn_> made some nice pretty lights I can still see when I blink..
[00:54:38] <ssi> I may try to repair it myself :P
[00:54:55] <ssi> I have a spare 5i25 on hand actually, earlier I got the propre firmware flashed on it and installed it in the machine
[00:54:58] <ssi> and my motion is working again
[00:55:00] <ssi> so that's good
[00:55:29] <PetefromTn_> yeah smoked the linear power supply real quick. the 7i77 was a casualty of the war.
[00:55:50] <PetefromTn_> Apparenlty the IO section may just need a chip or something like that according to Pete..
[00:56:04] <PetefromTn_> The other Pete... the one who knows what the hell is going on actually.
[00:56:10] <ssi> yeah that's what I figured
[00:56:22] <ssi> the field io processor
[00:56:27] <PetefromTn_> yup.
[00:56:49] <PetefromTn_> I shudder to think what it would have cost me if I did that with the original control tho...
[00:56:53] <ssi> heheh
[00:56:56] <PetefromTn_> Woulda broke me..
[00:57:05] <PetefromTn_> This was bad enought but just a couple hundred clams.
[00:57:07] <ssi> man someone linked a cincy 750 with a 4th axis in alabama for cheap
[00:57:13] <ssi> and I almost considered going to get it
[00:57:37] <PetefromTn_> I know a guy on the zone that has some that he got after his building burned.
[00:57:47] <PetefromTn_> He was apparently getting them setup and working.
[00:57:52] <PetefromTn_> perhaps it did not work out.
[00:58:06] <PetefromTn_> He contacted me occasionally about my buildup
[00:58:18] <PetefromTn_> mine is still not completed.
[00:58:30] <PetefromTn_> but at least I can make parts on the thing now.
[00:58:47] <PetefromTn_> Been making some pretty cool parts for precision airguns.
[00:59:08] <ssi> ya I've seen it :)
[00:59:22] <PetefromTn_> Sounds like you got enough toys already needing some love over there.
[00:59:35] <ssi> yeah :/
[00:59:48] <PetefromTn_> how big is that plasma?
[00:59:51] <ssi> 4x4
[00:59:56] <PetefromTn_> nice
[01:00:08] <PetefromTn_> I could use that machine here for sure.
[01:01:17] <ssi> when I get everything working right, I'm not gonna want to get rid of it :P
[01:01:37] <PetefromTn_> Well I better get my ass to bed I got some work to do in the morning. Still waiting on some parts I ordered for this other airgun. Paid for 2 day priority and got an email from USPS but it says it was never picked up for three days now...
[01:01:41] <ssi> yea
[01:01:44] <PetefromTn_> I'm sure...
[01:02:00] <PetefromTn_> how much ya got in it so far?
[01:02:08] <ssi> a lot
[01:02:09] <ssi> :P
[01:02:19] <PetefromTn_> yeah
[01:02:26] <ssi> probably $7k or so
[01:02:26] <PetefromTn_> Shits spensive...
[01:02:37] <PetefromTn_> ooh ouch.
[01:02:46] <PetefromTn_> For that much I would want a 4x8..
[01:02:53] <ssi> 4x8 torchmate is $20k
[01:03:02] <PetefromTn_> screw that I would build my own.
[01:03:17] <PetefromTn_> amazing people pay that much for them.
[01:03:20] <ssi> i could have done it cheaper
[01:03:25] <ssi> but I did it with profile rail
[01:03:32] <ssi> and 8' worth of profile rail is going to cost you out the ass
[01:03:42] <ssi> I bought my rails cheap, lucky finds
[01:03:43] <PetefromTn_> I guess it just comes down to do you want to make money and parts or make a damn machine.
[01:03:46] <ssi> and I still have $1k in rails
[01:04:06] <PetefromTn_> I would probably build that mechmate machine into a dual plasma/router setup..
[01:04:39] <ssi> I wanted to do that originally
[01:04:45] <ssi> but they're not really compatible
[01:04:52] <ssi> water table vs router bed
[01:05:03] <ssi> rigidity you need for a router is overkill for plasma
[01:05:08] <PetefromTn_> do you have a water table on yours?
[01:05:09] <ssi> one thing I'd love to have on this machine would be a plate marker
[01:05:10] <ssi> yes
[01:05:17] <ssi> or a center punch at least
[01:05:28] <ssi> cause plasma isn't great for small holes
[01:05:40] <ssi> so it'd be nice to be able to center punch all the drill hits under cnc
[01:05:44] <PetefromTn_> have you actually run it yet?
[01:05:49] <ssi> oh yeah I've run it for years
[01:05:53] <ssi> I'm just doing a big rebuild
[01:06:18] <ssi> https://www.youtube.com/watch?v=b3rhhnSkbfw
[01:06:21] <PetefromTn_> what is the thickest cut you can make that does not look like ass?
[01:06:27] <ssi> thicker's better actually
[01:06:33] <ssi> it'll pierce and cut 3/8 happily
[01:06:44] <ssi> it'll do 1/2, but piercing 1/2 is hard on the consumables
[01:08:06] <PetefromTn_> looks nice man but I swear it does not look like there is anything to this kind of machine really. Basic as hell.
[01:08:22] <ssi> it's pretty basic
[01:08:44] <ssi> but scratchbuilding machines is hard no matter what :)
[01:09:05] <PetefromTn_> I certainly could use one here maybe I need to just break down and build one.
[01:09:12] <ssi> do it
[01:09:19] <PetefromTn_> Yeah I have built quite a few machines over the years..
[01:09:22] <ssi> I know what I'd do differently if I had it to do over
[01:09:30] <PetefromTn_> buy one LOL
[01:09:32] <ssi> nah
[01:09:36] <ssi> I'd build another in a heartbeat
[01:09:41] <ssi> I wouldn't use profile rail for it tho
[01:09:55] <PetefromTn_> I swear you could build two and make money just selling the one.
[01:09:56] <ssi> and rather than a raised gantry, I'd do high sides
[01:10:04] <PetefromTn_> like the mechmate...
[01:10:07] <ssi> ya
[01:10:17] <PetefromTn_> Flattish gantry and high sides...
[01:10:22] <PetefromTn_> very easy and simple.
[01:10:24] <ssi> yep
[01:10:24] <PetefromTn_> less flex
[01:10:31] <PetefromTn_> great design really.
[01:10:33] <ssi> and I'd do belt drive
[01:10:41] <ssi> not super thrilled with the rack&pinion
[01:10:42] <PetefromTn_> belt or chain I guess.
[01:10:52] <ssi> I converted the X axis to belt during this retrofit
[01:11:04] <ssi> my only concern is i may need gear reduction on the stepper
[01:11:10] <PetefromTn_> a good timing belt kicks ass when you don't need crazy precision.
[01:11:13] <ssi> cause my fullstep size is 0.014 :/
[01:11:31] <ssi> and lcnc was doing something weird the other day
[01:11:36] <PetefromTn_> I would probably use servos.
[01:11:36] <ssi> if I do incremental jog
[01:11:43] <ssi> I can hit 0.010 jog ten times and the axis won't move
[01:11:49] <ssi> and I effectively lose motion that way
[01:11:56] <ssi> yeah servos would be a nice upgrade for this machine
[01:11:58] <PetefromTn_> NOT GOOD.
[01:12:03] <ssi> I know it's not good
[01:12:07] <ssi> and I don't know why it was doing that
[01:12:44] <PetefromTn_> I like how the mechmate uses hand ground rails.
[01:13:06] <ssi> I might try ahren's bearing system
[01:13:15] <ssi> now that I've seen it in person, I actually am impressed by it
[01:13:16] <PetefromTn_> its as precise as you are able to cut it.. take your time and be careful and it will be really nice.
[01:13:23] <PetefromTn_> what is that?
[01:13:27] <ssi> cncrouterparts.com
[01:14:48] <PetefromTn_> just runs on a rail then?
[01:14:58] <ssi> yeah, some CRS bars set at an angle
[01:15:23] <PetefromTn_> that is basically how the mechmate works sorta.
[01:15:50] <PetefromTn_> I could machine some mounts like that easy on the Cinci.
[01:16:00] <ssi> yeah see I still have no cnc mill :(
[01:16:25] <ssi> I could punt and buy a retrofit kit for my bridgie
[01:16:28] <ssi> but that seems sill
[01:16:31] <ssi> cause I like having a manual
[01:16:35] <PetefromTn_> and I have no CNC lathe :(
[01:16:42] <ssi> I have two :(
[01:16:50] <PetefromTn_> TWO!!
[01:16:54] <PetefromTn_> Bastard!!!
[01:16:58] <ssi> three lathes, two cnc
[01:17:09] <PetefromTn_> LOL
[01:18:16] <PetefromTn_> I am trying to find work for this thing all the time occasionally get some cool parts to make but it sits alot. Need to get it going before I think too seriously about another CNC machine I guess or my wife will kill me.
[01:18:16] * archivist giggles
[01:18:36] <PetefromTn_> laugh it up fuzzball...
[01:19:05] <archivist> I haz two lathes in the kitchen
[01:19:35] <ssi> ok I've stayed up entirely too late
[01:19:37] <ssi> thanks pete :)
[01:19:39] <ssi> night folks
[01:19:41] <PetefromTn_> https://www.youtube.com/watch?v=gqbdrA1Vjn4
[01:19:44] <PetefromTn_> me too
[01:19:48] <PetefromTn_> gnite
[01:20:05] <archivist> I have to go to the one day a fortnight job
[01:26:14] <Jymmm> archivist: steam powered re-enactement?
[01:26:26] <Jymmm> archivist: dress up in 200yo clothes?
[01:39:05] <archivist> no, windows an the email system
[01:41:25] <Jymmm> oh, heh
[01:41:47] <Jymmm> archivist: Would you like a few viruses and malware to take with you?
[02:00:48] <Deejay__> moin
[04:14:06] <q_p> how to use autoleveler with tb6560 ?
[04:50:01] <archivist_herron> what do you mean by autoleveler
[04:55:39] <Loetmichel> *gnah* <- dumbfuck... and the screw glue hae already cured... http://www.cyrom.org/palbum/main.php?g2_itemId=14987 +shit*
[04:56:32] <archivist_herron> guffaw
[05:47:01] <SpeedEvil> http://www.jewson.co.uk/tool-hire/earth-moving/excavators/products/6703/jcb-micro-mini-excavator/
[05:47:22] <SpeedEvil> A question arises if anyones heard of CNC conversions (well, add-ons) on excavators
[06:24:32] <archivist_herron> I do know farm tractors have automatic guidance but JCB erm never heard of it, methinks the job too variable to bother
[06:25:03] <archivist_herron> my old man used to work at JCB
[06:28:56] <SpeedEvil> It'd be quite nice to be able to say 'flatten that' and walk away
[06:29:04] <SpeedEvil> even if it's 20% as efficient as a person
[06:31:13] <Valen> Loetmichel: what is wrong in the picture?
[06:31:30] <Valen> I think there is too much variability
[06:31:45] <Valen> I mean what should it do if it hits a rock?
[06:32:08] <SpeedEvil> Either leave it, or call for help
[06:32:21] <SpeedEvil> And yes, it's not going to work in all terrain.
[06:32:30] <SpeedEvil> But - sandy soil with small rocks.
[06:33:37] <Valen> they will get there in the end
[06:33:50] <Valen> they are running dump trucks for the mines here totally automated
[06:33:57] <Valen> well one driver for like 30 trucks
[06:34:46] <SpeedEvil> There is always the stupid approach I guess.
[06:34:58] <SpeedEvil> Spindle, and a big carbide fly-cutter.
[06:35:15] <Valen> pshaw
[06:35:20] <Valen> plasma torch that sucker
[06:35:45] <Valen> I believe they are looking to automate the long wall mining operations and much more of the underground mining these days
[06:35:49] <SpeedEvil> yeah.
[06:36:01] <Valen> but they do actually use plasma for making foundations
[06:36:15] <SpeedEvil> It makes a crust?
[06:36:28] <Valen> they drill a hole, then run a plasma torch down it to turn it into glass basically
[06:36:43] <SpeedEvil> Interesting
[07:00:49] <RyanS> Is there any particular rule of thumb when to use 2, 3, 4 , flute endmills I know 4 is not recommended for deep slots
[07:15:59] <jdh> there are various online feed/speed calculators that will show you what happens. Usually chip load is specified.
[07:18:21] <Tom_itx> http://zero-divide.net/index.php?page=fswizard&shell_id=199&load_tool_id=27011
[07:18:26] <Tom_itx> that's a pretty good one
[07:21:24] <RyanS> So the material and operation type is not how number of flutes are selected?
[07:21:43] <jdh> sure. as are spindle speed, machine power, etc
[07:24:09] <RyanS> I suppose more cutting edges require more power
[07:34:05] <archivist_herron> more cutting edges means less clearance for chips
[07:35:34] <RyanS> That's why you don't use a four for slots?
[08:05:05] <Jymmm> I know I can use a "V" Slot to center a round object. Is there something I can use to center a rectangular object?
[08:06:43] <mozmck> vise and measuring tools
[08:07:18] <Jymmm> Yeah, no. This is for an alignment jig
[08:08:03] <Jymmm> The objects width it arbitrary.
[08:08:33] <Jymmm> as it can vary.
[08:09:20] <mozmck> maybe a centering vise then.
[08:09:52] <mozmck> http://www.grizzly.com/products/Precision-Self-Centering-Vise/H7576
[08:10:40] <Jymmm> Do they come in 1/8" tall versions?
[08:10:48] <mozmck> Of if that's too cheap: http://www.kurtworkholding.com/self-centering-vise-p-1190-l-en.html
[08:11:37] <mozmck> total height?
[08:11:41] <Jymmm> It doens't need to be clamped
[08:11:50] <Jymmm> total height, yes.
[08:12:58] <mozmck> I wouldn't think so. What is this for?
[08:13:49] <Jymmm> See, for round objects I can just create a plate with a V-Slot, anyting round placed in the slot is perfectly centered. I just need the same thing for rectangular objects.
[08:14:59] <mozmck> Yes, but you can't just make a slot for them if they will vary in width. What is the application though? Drilling holes?
[08:15:01] <Jymmm> Alignment jig for my laser.
[08:16:31] <mozmck> can't think of anything as simple as a slot. a fence adjusted with a screw would work and could be made thin.
[08:17:43] <mozmck> still have to measure though.
[08:17:55] <Jymmm> Yeah, the only thing I could think of is a "staircase", but that would only work for known widths.
[08:20:35] <jdh> two diagaonal corners with wheels, cable, constraints?
[08:21:00] <Jymmm> How do centering vises work? Both jaws close at the same time, but how do you know that's "center" and not shifted one side or another?
[08:21:32] <Jymmm> jdh: Say that again?
[08:21:46] <mozmck> the screw has left and right hand threads.
[08:22:50] <Jymmm> mozmck: Right, but when the jaws are closed 100% with nothing in them, how do you know that's "center", and not center -10 ?
[08:22:50] <mozmck> so if everything is tight and accurate, the jaws always move the same distance opposite ways
[08:23:15] <jdh> you will have to reference whatever it is at least once
[08:23:25] <mozmck> You have to center the whole vise obviously to start with.
[08:23:35] <Jymmm> jdh: Does that ever change?
[08:23:52] <jdh> if you move it
[08:23:59] <Jymmm> So, no. ok
[08:24:10] <Jymmm> Just asking =)
[08:24:34] <Jymmm> I thought there might have been calibrated center line on the vise themselves
[08:25:04] <mozmck> There might be - I don't know.
[08:25:09] <Jymmm> k
[08:27:08] <Jymmm> jdh: what were you saying about diaganol corners?
[08:27:42] <jdh> like a pantograph mechanism sort of.
[08:28:00] <jdh> where the two corner parts come in/out together
[08:28:20] <Jymmm> Oh, hmmm.
[08:30:08] <Jymmm> The reason I was asking how a centering vise works is I was thinking like the jaws of a pair of calipers sorta thing for centering rectangular objects.
[08:30:49] <Jymmm> bbiab
[08:43:52] <jdh> 25% off at onlinemetals.com today
[08:57:52] <Jymmm> with free shipping?
[09:00:06] <jdh> sadly, nope.
[09:00:21] <jdh> I added some 24x24" hdpe and the shipping went way up
[09:01:02] <Jymmm> Oh yeah, how thick?
[09:01:12] <jdh> .375 and .5
[09:01:23] <Jymmm> It's not called HIGH DENSITY for nothing =)
[09:01:34] <jdh> and some misc. 6061, 24" long
[09:02:08] <Jymmm> how much was the 1/2" hdpe?
[09:02:21] <jdh> $33 for the .5"
[09:02:28] <Jymmm> grey?
[09:02:31] <jdh> black
[09:02:43] <mozmck> The stuff I've looked at on onlinemetals (metal) is too expensive.
[09:03:03] <mozmck> local metal suppliers are way cheaper
[09:03:17] <jdh> I have no local metal suppliers
[09:03:31] <jdh> so expensive or not, it is there and easy.
[09:04:30] <mozmck> interesting. where are you?
[09:04:32] <Jymmm> $33 for 2sf of 1/2" hdpe is cheap
[09:04:57] <jdh> actually it was $24 for 12x24
[09:05:32] <jdh> and that will fit in my router without cutting it first.
[09:05:58] <jdh> weird...the 3/8 was $27
[09:06:01] <Jymmm> Why HDPE?
[09:06:26] <jdh> why not? cuts well. weather resistant
[09:06:27] <mozmck> http://www.usplastic.com/catalog/item.aspx?itemid=36174&catid=705
[09:06:42] <Jymmm> jdh: If it has UV inhibitors in it.
[09:07:39] <mozmck> $50 for 8sf 1/2" hdpe
[09:07:56] <jdh> http://tinyurl.com/ohmuue9
[09:08:06] <jdh> I want something similar to that.
[09:09:08] <Jymmm> keep tanks fro rolling in the car?
[09:09:34] <jdh> scooter on the boat
[09:09:46] <Jymmm> ah
[09:10:04] <jdh> http://www.aquanauts.co.uk/halcyon-hdv-t16-dive-scooter-dpv
[09:10:10] <mozmck> maybe you want this then: http://www.usplastic.com/catalog/item.aspx?itemid=102717&catid=705
[09:10:13] <jdh> different scooter, but same thing
[09:10:34] <jdh> yeah, I can buy that locally
[09:10:37] <jdh> it's just a pain
[09:10:55] <Jymmm> jdh: YEah, the last link mozmck gave states UV Stablized, and for salt water too
[09:10:59] <jdh> I use taht for stuff that stays on my boat
[09:11:12] <jdh> but this will live with my scooter so it goes inside after diving.
[09:11:53] <jdh> and I'd rather have it show up at my door than have to deal with the local place
[10:12:09] <ssi> hrm
[10:13:19] <jdh> hrm?
[10:13:24] <JT-Shop> I have some steel parts cut with the plasma and I need to deburr them. I have a sand blaster but that sucks
[10:13:48] <JT-Shop> I also have a concrete mixer can I use that with some local media to clean parts?
[10:14:35] <mozmck> I'm sure you could! tumble them around in sand or gravel a little
[10:15:22] <mozmck> I usually used a file or junk chisel to remove the slag, and a flap sanding disk on an angle grinder.
[10:15:23] <_methods> needler
[10:15:27] <archivist_herron> we used a barrel to clean parts, you can buy various compounds for for rough to polish
[10:15:33] <ssi> JT-Shop: I'd love to see some pics of what comes off your plasma
[10:15:41] <ssi> and what kind of burr you're talkin
[10:15:52] <_methods> best thing i've found is the 60 grit flapper whells
[10:15:54] <_methods> wheels
[10:16:46] <SpeedEvil> http://www.arrowcryogenics.com/thermal.htm
[10:16:52] <JT-Shop> ssi, a burr like is left when you through drill sheet metal parts
[10:17:12] <JT-Shop> and remove the dross from the plasma
[10:17:14] <SpeedEvil> ^thermal flash deburring
[10:17:43] <ssi> JT-Shop: i get a little roll of dross
[10:17:48] <JT-Shop> probably not something you can find at Menards
[10:18:15] <ssi> I usually can knock it off with another heavy chunk of plate, but it's usually a pain in the ass
[10:18:28] <_methods> i'm talking about the flapper disks not the flapper wheels
[10:18:29] <mozmck> JT-Shop: the flap sanding wheels work well. If the cut is good the dross usually knocks off quite easily.
[10:18:36] <JT-Shop> for me it depends on how dirty the metal is, I usually take a small ball peen hammer and tap the edge
[10:18:37] <_methods> sorry everyone around here calls them flappers wheels
[10:18:48] <_methods> http://www.grainger.com/product/23Z578
[10:19:02] <JT-Shop> flap wheel like you mount on a bench grinder?
[10:19:08] <_methods> yeah
[10:19:10] <_methods> no
[10:19:14] <_methods> angle grinder
[10:19:23] <_methods> they last longer than rocks
[10:19:34] <_methods> and work good on plasma dross
[10:19:47] <mozmck> I'll second that.
[10:19:54] <_methods> more forgivin too if you got retards on the grinders
[10:20:07] <JT-Shop> I'm the retard
[10:20:08] <_methods> rocks can be dangerouns in the hands of a gorilla
[10:20:10] <ssi> haha
[10:20:23] <_methods> hehe
[10:20:43] <JT-Shop> I have 4 1/2" flap wheels from 40 to 120 grit for my angle grinder and one flap wheel on a polisher
[10:20:53] <_methods> we get the norton double thick one
[10:20:56] <_methods> ones
[10:21:11] * JT-Shop looks at the big stack of parts to clean up...
[10:21:11] <_methods> they seem to last pretty good
[10:23:16] <JT-Shop> http://blog.cnccookbook.com/2012/08/11/part-tumbler-for-vibratory-finishing-on-the-cheap/
[10:24:10] <mozmck> IoT - latest buzzword, should tack it on the linuxcnc description somewhere
[10:24:24] <archivist_herron> you need ear muffs for a tumbler :)
[10:24:31] <ssi> I tried vibratory tumbling with those green diamonds
[10:24:35] <ssi> it didn't work remarkably well
[10:24:47] <jdh> JT: the guy I sell my shark teeth two has 3 that look like that.
[10:24:48] <JT-Shop> I know vibratory finishing is the best/fastest but I don't do this often enough to get a $5k machine
[10:25:24] <JT-Shop> yea the tumbler would have to be outside while running
[10:25:29] <archivist_herron> ours was homebrew wooden 6 or 8 sided
[10:25:54] <mozmck> acid dip for several hours and rinse well. slag pretty much falls off.
[10:26:11] <jdh> sided vs. round sounds like it woudl tumble better
[10:26:13] <JT-Shop> I designed some tumblers for the nail factory I used to work for and they worked so well they still use that design
[10:26:35] <JT-Shop> mozmck, what kind of acid?
[10:26:42] <mozmck> hcl
[10:26:57] <Jymmm> Heh, "Nail factory", sounds like something from the 1800's
[10:27:00] <mozmck> Don't know if that's best for your objective or not.
[10:27:23] <ssi> I setup an anodizing station awhile back
[10:27:29] <mozmck> sure gets it clean for finishing.
[10:27:30] <ssi> hated having to have acid around
[10:27:36] <ssi> and strong alkaline too
[10:27:46] <ssi> ate up my clothes, was worried about what it'd do to the machines
[10:28:05] <JT-Shop> I have muriatic acid or battery acid on hand
[10:28:09] <mozmck> yeah, we had it in a tub outside.
[10:28:13] <mozmck> muriatic is hcl
[10:28:21] <mozmck> battery is sulferic
[10:28:23] <Jymmm> mozmck: is it?
[10:28:32] <Jymmm> mozmck: HCL that is?
[10:28:40] <ssi> yeah muriatic is dilute hcl
[10:29:04] <mozmck> yeah - same thing as in your stomach
[10:29:05] <Jymmm> Oh well, then just burn up some PVC then, instant HCL =)
[10:29:12] <mozmck> or just barf :)
[10:29:20] <Jymmm> Ewwwwwwwww
[10:30:02] <JT-Shop> yep mine is 30% hcl
[10:30:42] <JT-Shop> do you use baking soda to neutralize the parts after?
[10:31:53] <mozmck> I don't remember now - it's been a number of years. I think I might have rinsed, then soaked in water with baking soda.
[10:32:15] <mozmck> I don't remember how dilute the acid solution was either.
[10:33:09] <JT-Shop> I used that to de-rust the inside of my '56 tractor gas tank
[10:33:38] <mozmck> Yes, that's partly why we used the acid, removed *all* rust before power coating.
[10:33:44] <JT-Shop> looks like I didn't get the bottle clean as it is making my shelves rust
[10:36:20] <Jymmm> JT-Shop: Unless it came sealed in a plastic bag, I've never had anything "clean".
[10:36:45] <Jymmm> Even then, I've had acid on the bag too.
[10:37:32] <jdh> I broke down and ordered my chinese router
[10:37:46] <Jymmm> My hands are sensative to acids. Even giving someone a jump start I can feel the acid on my hands. I always carry baking soda as just water/soap never work.
[10:40:27] <jdh> wear gloves?
[10:44:53] <Jymmm> Not always practical, and I don't want to eat thru my leather ones
[10:45:10] <mozmck> I washed a battery off once pretty thoroughly, then carried it across the yard. A little water off the top fell off on my knee and before I got across the yard the knee of my jeans ripped out.
[10:45:14] <Jymmm> jump starting that is. Other times, I do
[10:45:29] <ssi> mozmck: yeah I've been through a lot of that crap
[10:45:55] <Jymmm> mozmck: you suck at washing is all =)
[10:45:59] <mozmck> I didn't realize it would do something that quickly at the time.
[10:45:59] <ssi> airplane batteries are mostly Gill pieces of shit, and you have to fill them when you get them, and they have ball checkvalve cell caps
[10:46:03] <ssi> so there's always acid everywhere
[10:46:25] <ssi> it's awesome cause they leak acid in their battery box
[10:46:37] <mozmck> I think some acid may have seeped from under the cap, but it would have been diluted.
[10:46:38] <ssi> always good to see the corrosion in your freakin airframe because of your stupid pos battery
[10:46:52] <mozmck> heh, you get to pay 4x for that too!
[10:47:10] <ssi> yeah the last gill I bought I had to pay over $300 for
[10:47:22] <ssi> because I was stranded in new jersey and at the mercy of the mechanic on the field that happened to have one
[10:47:23] <Jymmm> SUCKER
[10:47:42] <ssi> sucker maybe, but I wanted to get the hell out of new jersey before the snowstorm hit
[10:47:44] <Jymmm> ssi: Ya should have called AAA =)
[10:47:55] <mozmck> no, you have to get an FAA str to put in a different battery :)
[10:48:08] <Jymmm> DIY
[10:48:09] <ssi> mozmck: thankfully no, I just had to pay rapey prices for the battery
[10:48:12] <mozmck> or battery hold-down nut.
[10:48:18] <ssi> it's legal for me to put in my own battery :P
[10:48:26] <ssi> or is it? I can't remember now
[10:48:31] <ssi> regardless, I certainly WILL
[10:48:34] <Jymmm> ssi: AvTech?
[10:48:35] <CaptHindsight> that's why in the good-ol days they used hand cranks
[10:48:44] <mozmck> :) maybe I'm exaggerating a little, but it's pretty crazy.
[10:48:56] <ssi> CaptHindsight: I can hand prop my plane, but it's not anything like safe to try to do alone
[10:49:03] <mozmck> cranks? just the prop
[10:49:04] <ssi> cherokees aren't designed to be hand propped
[10:49:17] <ssi> with two qualified people it's not too bad
[10:49:27] <ssi> but lots of people have been killed trying to hand prop planes without knowing what they're doing
[10:49:54] <mozmck> friend of mine hand-props his taylorcraft from behind while standing in the door
[10:50:12] <mozmck> leaning out of the plane that is.
[10:50:19] <ssi> yes, tcraft is designed to do so
[10:50:41] <ssi> it's probably a c65 or c90, low compression, easy to flip through
[10:50:46] <mozmck> yes, but most things I've seen have you stand in front so you'll get sucked into the prop :)
[10:50:48] <ssi> light prop, plus you can get to it from the cockpit
[10:51:01] <ssi> and it's a taildragger so the prop is up in the air, so you have a big swing angle
[10:51:05] <mozmck> yes, c65 I think
[10:51:22] <ssi> cherokee is 150hp, higher compression, big heavy prop, and you have to walk all the way around the wing to get in once it's running
[10:51:32] <ssi> and don't have good access to the gear to have a chock on a line
[10:51:44] <mozmck> I just had not heard of hand propping from the cockpit.
[10:51:47] <ssi> and it's nosewheel, so the prop is at chest level
[10:53:55] <jdh> PayPal balance: $0.00 USD
[10:54:18] <jdh> too bad I didn't have room for that Monarch instead
[10:54:31] <ssi> wat
[11:00:44] <jdh> I passed up a Monarch 10EE for a chinese router
[11:01:21] <ssi> what made you decide against the monarch
[11:01:24] <ssi> that was a nice lathe :D
[11:01:33] <jdh> room, and abillity to move it.
[11:01:33] <ssi> maybe I should go get it :P
[11:09:17] <ssi> ugh I'm super add today :(
[11:11:48] <CaptHindsight> jdh: please let me know how they mount the ballscrews on that router
[11:12:22] <jdh> pics show straight down
[11:12:42] <jdh> but, If it has enough balls, that is fine
[11:13:18] <CaptHindsight> http://machinedesign.com/site-files/machinedesign.com/files/archive/motionsystemdesign.com/images/main-types894.jpg
[11:13:40] <CaptHindsight> I'm wondering about the ends and if the limited pics match the actual as shipped version
[11:13:46] <ssi> "end fixity"
[11:14:13] <ssi> CaptHindsight: what is "C" in that diagram?
[11:14:22] <jdh> oh... screws. gotcha
[11:14:30] <CaptHindsight> http://machinedesign.com/linear-motion/importance-ballscrew-end-fixity
[11:15:45] <ssi> I see
[11:15:53] <jdh> I'm assuming they are fixed + floating
[11:16:32] <CaptHindsight> the ones I got through automation technology used the free floating on both ends :)
[11:16:45] <ssi> jdh: have a link to the router you bought?
[11:16:57] <jdh> http://www.carving-cnc.com/cnc6040-series/cnc-6040z-s80-new-router-engraver-drilling-and-milling-machine.html
[11:17:36] <CaptHindsight> I had to rework them for proper alignment
[11:18:07] <JT-Shop> ssi, mozmck http://www.gnipsel.com/images/plasma/Cut-Parts.jpg
[11:18:22] <CaptHindsight> I see a nut on the end of the Y axis but I can't see the others
[11:18:27] <jdh> how does that even work if they both float?
[11:18:42] <ssi> JT-Shop: that post-acid?
[11:18:52] <JT-Shop> few minutes in hcl, baking soda rinse, fresh water rinse, rinse in plasma quench
[11:19:04] <JT-Shop> yea, you should see the rusty crap I cut them from
[11:19:07] <ssi> looks pretty good
[11:19:15] <CaptHindsight> 1-2mm of lash :) the motor bearings were the stop on one end
[11:19:18] <JT-Shop> a lot better than my sand blasting
[11:19:27] <ssi> lot quicker too
[11:19:48] <ssi> jdh: what did shipping cost, and how long will it take to shop?
[11:19:49] <ssi> ship
[11:20:43] <jdh> $372 shipping. Dunno how long yet.
[11:20:50] <ssi> yow
[11:20:59] <jdh> fedex
[11:21:03] <JT-Shop> yea, just need a way to get the acid and parts separated after the soak
[11:21:12] <ssi> I'm interested to see how it is when you get it
[11:21:22] <jdh> me too!
[11:21:34] <ssi> JT-Shop: fry basket :)
[11:21:42] <jdh> I have to get rid of my old one to make room
[11:22:07] <ssi> what's your old one
[11:22:20] <jdh> 80% HPDE
[11:22:22] <JT-Shop> lol I tried to use a grease cover for a pan but it turned out to be aluminum
[11:22:25] <jdh> rest plywood and MDF
[11:22:33] <CaptHindsight> nalgene fry basket
[11:22:40] <ssi> JT-Shop: I don't think acid will kill aluminum actually
[11:22:52] <JT-Shop> well it turns it to smoke
[11:23:03] <ssi> hm
[11:23:09] <ssi> I'm trying to remember what the deal was with anodizing
[11:23:14] <ssi> I was using sulfuric, but
[11:23:15] <JT-Shop> and turned it black
[11:23:20] <ssi> the lye would eat the surface
[11:23:22] <ssi> and the acid wouldn't
[11:23:36] <JT-Shop> for an acid etch?
[11:23:40] <ssi> for anodizing
[11:23:46] <ssi> I dunno, it's been awhile
[11:23:49] <ssi> don't trust me :)
[11:23:51] <JT-Shop> yea, I have an anodizing line
[11:24:14] <JT-Shop> out in a wooden shed but I've not fired it up yet
[11:24:52] <JT-Shop> I need to anodize these parts http://gnipsel.com/spyderstore/index.php?route=product/product&product_id=65
[11:25:13] <archivist> etch bath, anodise bath colours dip and then a filler
[11:25:27] <JT-Shop> yep
[11:25:37] <JT-Shop> and a degreaser up front
[11:26:11] <archivist> the filler was lanolin hand rubbed on in those days
[11:26:14] <JT-Shop> etch is only needed for some alloys, I use 6061 which does not need the etch
[11:26:40] <CaptHindsight> JT-Shop: if you use solvent dye you can get fancy with patterns
[11:26:49] * JT-Shop wanders inside to fix a bowl of gruel
[11:27:00] <JT-Shop> I just need blue
[11:27:04] <ssi> I want gruel
[11:27:22] <jdh> that sounds awful
[11:27:40] <jdh> isnt' that what you feed orphans in the home?
[11:27:57] <JT-Shop> the lucky orphans yes
[11:28:32] <ssi> ugh there are six coffee mugs crowding my desk
[11:28:51] <mozmck> JT-Shop: we used to use steel welding wire to hang parts down in the acid. They were larger though and more intricate.
[11:29:30] <CaptHindsight> anyone found good coolant sump pumps for small machine retrofits?
[11:29:32] <mozmck> You could pour off the acid through a strainer - fry basket - etc, into another container.
[11:29:54] <CaptHindsight> that don't easily clog from gruel and swarf
[11:32:53] <CaptHindsight> http://bedair.org/Grizzly12x/GrizzlyG4003G5.html Inexpensive Coolant System, a bit low budget
[11:35:45] <archivist> we used to pump diesel with a water service (caravan parts supplier) submersible, it worked for a long time
[11:37:31] <jthornton> ssi, I forgot to ask what happens when you just turn on the lift solenoid?
[11:37:56] <ssi> jthornton: I dunno; it's been over a year since I messed with it
[11:39:02] <jthornton> ok, just wondering
[11:39:14] <ssi> jthornton: I'll get into it soon
[11:40:17] <CaptHindsight> http://www.harborfreight.com/merchandising-promotions/merchandising/outdoor-categories-for-seo/fountain-pumps/200-gph-miniature-submersible-fountain-pump-68372.html hard to beat $11 even if you replace it every year
[11:42:35] <jthornton> just found the turret photos
[11:43:41] <ssi> oh sweet
[11:43:51] <archivist> CaptHindsight, we were using a 12v one, a bit safer in the diesel I suppose
[11:44:30] <CaptHindsight> archivist: did you submerge it in diesel?
[11:44:48] <archivist> yes
[11:45:25] <archivist> could have been this make, http://www.commercialfuelsolutions.co.uk/whale_standard_sub_pump.html?gclid=CPreocu4lb8CFWfkwgodDUIACw
[11:45:34] <jthornton> they don't show as much as I thought
[11:48:19] <archivist> mine is so old the writing has disappeared and the cable is different
[11:50:04] <archivist> at the price, we did not care how long they lasted with the abuse we gave them
[11:50:23] <CaptHindsight> yes, thinking the same
[11:50:53] <archivist> we only dunked them in during pumping though, never left them to melt
[11:51:51] <zeeshan|3> CaptHindsight: hi!
[11:52:36] <CaptHindsight> zeeshan|3: hey, get your lathe done?
[11:52:55] <zeeshan|3> CaptHindsight: yes
[11:52:55] <zeeshan|3> but
[11:53:01] <zeeshan|3> i am about to buy something
[11:53:07] <zeeshan|3> wondering if you had a better solution
[11:53:13] <Loetmichel> archivist: as long as the diesel isnt boiling i would have no problems with 230V submerged in diesel ;-)
[11:53:14] <zeeshan|3> http://www.tegstools.com/King-Canada-KHP-20T-20-Ton-Hydraulic-Shop-Press_p_779.html
[11:53:19] <zeeshan|3> 20 ton press, with gauge
[11:53:51] <zeeshan|3> 37 1/2" working range
[11:54:02] <zeeshan|3> ive been lookling on kijij for about a month now, nothing close has come by
[11:55:37] <CaptHindsight> zeeshan|3: depends on who did the welding that day
[11:55:47] <zeeshan|3> its not welded
[11:55:49] <zeeshan|3> its a bolted assembly
[11:55:55] <zeeshan|3> and pin
[11:56:04] <zeeshan|3> (in the crucial locations)
[11:56:14] <zeeshan|3> i dunno if there is a press for cheaper
[11:56:22] <CaptHindsight> then you shouldn't have the problems others have had
[11:56:34] <zeeshan|3> find me a press for cheaper!
[11:56:37] <CaptHindsight> I went through 3 from HF
[11:56:44] <archivist> make a press
[11:56:59] <archivist> just buy the hydraulics
[11:57:42] <zeeshan|3> archivist: its not cheaper to do that
[11:57:48] <zeeshan|3> the hydraulic are usually expensive
[11:57:49] <CaptHindsight> I checked all the welds, then got it back to the shop to discover that the gap between the upper beams where the return springs go was too narrow
[11:58:53] <CaptHindsight> no craigslist specials zeeshan|3 ?
[11:58:58] <zeeshan|3> no :(
[11:59:04] <zeeshan|3> ive been looking for about a month month and a half
[11:59:22] <zeeshan|3> the only thing that popped up with a 12ton
[11:59:31] <CaptHindsight> they show up, this time of year is not great for shop tools
[11:59:32] <zeeshan|3> but it had external spring returns
[11:59:34] <zeeshan|3> i didnt really dig it
[11:59:43] <zeeshan|3> CaptHindsight: but i need it nowww!
[11:59:46] <CaptHindsight> everyone cleaned out late winter
[11:59:48] <zeeshan|3> need to build my transmission
[12:00:18] <archivist> same stuff over here http://www.machinemart.co.uk/shop/search/filter/hydraulic-presses/type/any/module/shopcategory/page/1
[12:00:19] <CaptHindsight> heh, tough without a press
[12:00:31] <zeeshan|3> i got most of the bearings off without a press
[12:00:35] <zeeshan|3> but theres a couple of them i need a press
[12:00:37] <zeeshan|3> =/
[12:00:52] <archivist> some pullers can be used
[12:00:58] <CaptHindsight> rubber mallet and sandbox
[12:01:08] <zeeshan|3> its just easier and cleaner and less damaging
[12:01:10] <zeeshan|3> to use a press :P
[12:01:14] <zeeshan|3> cause you can align it right
[12:01:45] <zeeshan|3> http://www.machinemart.co.uk/shop/product/details/clarke-csa20f-20-tonne-hydraulic-press
[12:01:46] <zeeshan|3> wow
[12:01:48] <zeeshan|3> thats a sexy press
[12:01:49] <zeeshan|3> beefy
[12:02:29] <archivist> look on fleabay too
[12:02:38] <zeeshan|3> shipping might be too much for a 200lb item
[12:02:43] <zeeshan|3> thats why i didnt look at ebay
[12:03:02] <CaptHindsight> http://detroit.craigslist.org/okl/tls/4506878091.html
[12:03:41] <zeeshan|3> welded assembly!
[12:03:42] <zeeshan|3> :P
[12:03:53] <zeeshan|3> i like the casters on it
[12:04:18] <jdh> looks like a HF special
[12:04:26] <zeeshan|3> hehe

[12:13:02] <ssi> SpeedEvil: THIS IS COOL
[12:13:24] <ssi> SpeedEvil: I read a 17th century book on woodworking that had a whole chapter on geometry with a compass and straightedge
[12:13:32] <ssi> SpeedEvil: and I worked through the examples... was fun :)

[12:23:17] <archivist> CaptHindsight, looks like it, specially with krups in the margin
[12:23:48] <archivist> CaptHindsight, I went to see a similar one in the UK
[12:26:20] <archivist> CaptHindsight, I was ere (next to photog) http://www.geograph.org.uk/photo/1668885
[12:27:46] <archivist> middle ram has been removed, it was 12000 ton
[12:29:53] <CaptHindsight> archivist: ever been around one while it's working? http://s0.geograph.org.uk/photos/24/14/241439_fa759b13.jpg
[12:29:58] <ssi> SpeedEvil: seven is tough
[12:31:01] <ssi> SpeedEvil: it wouldn't be hard with a compass, would just draw parallel line, set compass to A->B, and use that to scribe an arc across the parallel from C
[12:31:08] <ssi> but don't have such tool in here :)
[12:31:54] <SpeedEvil> It should have a way to look back.
[12:31:55] <archivist> CaptHindsight, steam hammer, better than that, used one also if you follow Chris allens pics we went to the Hillsfoot forge the same day iirc with about 4 hammers being used
[12:32:18] <SpeedEvil> you get a compass next lvel IIRC
[12:32:20] <ssi> SpeedEvil: you mean at your previous level solutions?
[12:32:22] <ssi> hm
[12:32:26] <SpeedEvil> yes
[12:33:54] * SpeedEvil is stumped on 14.
[12:34:07] <ssi> :)
[12:34:33] <CaptHindsight> archivist: does the ground shake?
[12:35:13] <archivist> erm yes, this is the other site we went to that day http://www.geograph.org.uk/photo/1689068
[12:36:02] <CaptHindsight> http://www.youtube.com/watch?v=msLm4uPxTr0 13000 Ton large forging press
[12:36:27] <archivist> there is usually a wooden shock absorber below a steam hammer
[12:36:44] <CaptHindsight> was wondering what the dampener might be
[12:38:02] <CaptHindsight> 50,000-ton Press http://www.youtube.com/watch?v=WPjVSryWC1A
[12:54:36] <ssi> SpeedEvil: yeah 14 is tough
[12:55:08] <SpeedEvil> I'm now stuck on 15, and taking a break :)
[12:55:54] <SpeedEvil> Think about bisection
[12:56:12] <ssi> yeah that's where I was going
[12:56:46] <ssi> the intersection of the bisected angles is clearly the center of the circle
[12:56:53] <ssi> just have to figure out how to get the tangent point on the triangle
[12:57:40] <ssi> ah got it
[12:57:41] <ssi> :D
[13:23:11] <CaptHindsight> SpeedEvil: you think that's tough, you should try the one on non-Euclideran geometry :)
[13:23:33] <CaptHindsight> non-euclidean
[13:23:35] * SpeedEvil saddles-up.
[13:24:26] <ssi> 17 is tough
[13:26:34] <ssi> got it :D
[13:28:36] <SpeedEvil> I think I see where to go on 17
[13:29:56] <IchGuckLive> hi paideia
[13:31:18] <IchGuckLive> ssi: i thughtr you need to find time and now playing around ;-)
[13:31:32] <ssi> IchGuckLive: I'm on the clock
[13:31:39] <ssi> which means I can't go down to the basement and work on machines
[13:31:44] <ssi> I have to sit here and monitor this stupid demo
[13:31:53] <IchGuckLive> ok
[13:32:42] <IchGuckLive> ok im off for today tomorrow Gerany is playing and big partys here al over maybe not to stand online
[13:33:10] <IchGuckLive> Germany vs USA
[13:33:31] <IchGuckLive> or as in Championship mode USA vs Germany
[13:33:37] <IchGuckLive> BYE
[13:51:52] <paideia> hi
[13:53:41] <_methods> http://www.theverge.com/2014/6/25/5842108/google-announces-drive-for-work-with-unlimited-storage-at-10-a-month
[13:53:53] <_methods> unlimited for $10/month jeebus
[14:19:14] <Connor> _methods: PER USER
[14:19:20] <_methods> yeah
[14:19:23] <_methods> looks that way
[14:26:48] <jdh> Connor: I broke down and sent my money for the 6040
[14:27:40] <_methods> hey you finally did it
[14:27:43] <_methods> right on
[14:29:34] <jdh> it's not like I should have spent the cash on a car for my kid.
[14:55:36] <CaptHindsight> can the Google drive be setup as shared reads like a web file server?
[14:56:09] <_methods> i'm not sure
[14:56:12] <_methods> i rarely use mine
[14:57:13] <_methods> http://xmodulo.com/2013/10/mount-google-drive-linux.html
[14:57:24] <_methods> looks like you can use ocamlfuse
[14:57:29] <_methods> and mount like any other drive
[14:58:11] <CaptHindsight> say you have compressed binaries -500MB and only want shared reads for many, and write only for admin
[14:58:28] <_methods> yeah i don't know about permissions in there
[14:58:32] <_methods> i'm assuming so
[14:58:38] <CaptHindsight> anonymous reads
[14:58:42] <_methods> yeah
[14:58:50] <CaptHindsight> they probably don't allow that
[14:58:57] <_methods> my plan was maybe to use it for my plex server
[14:59:04] <_methods> keep all my movies heheh on there
[14:59:30] <_methods> don't even touch my home server
[14:59:41] <_methods> have a seed box funneling movies into my google drive
[14:59:52] <_methods> then mount the google drive in my plex media server
[15:01:45] <_methods> https://developers.google.com/drive/v2/reference/permissions/update
[15:03:15] <CaptHindsight> I wonder how many GB and users before they throttle the connection?
[15:03:30] <_methods> i have no idea
[15:03:33] <CaptHindsight> to truly replace dropbox
[15:03:35] <_methods> it's google so
[15:03:46] <_methods> they may be tryin to kill dropbox and bitcasa
[15:03:51] <ssi> oh man that was stressful :P
[15:04:27] <_methods> what?
[15:04:49] <ssi> there's a company that does job interviews via live assesment, they build you a vm and give you a set of timed tasks
[15:04:54] <ssi> some sysadmin tasks, some programming tasks
[15:04:57] <ssi> 60 minutes to do it
[15:05:05] <_methods> ah cool
[15:05:15] <ssi> when your time is up it just dumps you out of the vm
[15:05:52] <_methods> kobayashi maru
[15:07:44] <CaptHindsight> https://developers.google.com/drive/web/manage-downloads at the bottom
[15:08:19] <CaptHindsight> so it should work
[15:08:29] <_methods> yeah
[15:08:36] <_methods> nice sdk for it too
[15:08:41] <_methods> you can even convert docs
[15:08:58] <_methods> examples in 7 languages
[15:09:15] <CaptHindsight> this could even replace imagebin
[15:09:34] <_methods> i mean $10/month for unlimited storage
[15:09:39] <_methods> i'll find a use for that
[15:10:00] <CaptHindsight> public stuff you don't care about keeping private
[15:10:04] <_methods> exactly
[15:10:25] <ssi> i want to build myself a decent image hosting service that I can use quickly
[15:10:31] <ssi> there's nothing out there I've been happy with
[15:10:32] <CaptHindsight> or if it disappears due to some "software glitch"
[15:10:41] <ssi> I end up using twitter as that
[15:10:47] <ssi> cause I can take a pic with my phone and tweet it, and it's hosted
[15:10:50] <ssi> kinda terrible
[15:10:55] <CaptHindsight> yeah
[15:10:59] <_methods> well i don't trust google
[15:11:03] <_methods> after the reader thing
[15:11:08] <ssi> wise not to trust them :P
[15:11:08] <_methods> they love to cancel shit
[15:11:14] <ssi> the storage and hosting isn't a problem for me
[15:11:17] <_methods> well besides the spying thing
[15:11:24] <_methods> they just love to kill projects
[15:11:26] <ssi> I've got a colo'd server with 16TB raid6 and 2500GB/mo bandwidth
[15:11:31] <_methods> jesus
[15:11:33] <ssi> and it's almost unutilized as it is
[15:11:33] <_methods> how much is that?
[15:11:44] <ssi> $165/mo, including the two netblocks I have
[15:11:47] <ssi> have routed netblock and everything
[15:12:01] <ssi> and it's an esx server, so as many vms as I can run on it at atime
[15:12:10] <_methods> damn that's kinda nice
[15:12:23] <_methods> and you ahve access to 2 netblocks?
[15:12:29] <ssi> yeah... yet another of my stupid projects that costs me money every month but I do nothing with
[15:12:36] <_methods> who the hell is that with
[15:12:43] <ssi> yeah there's a little netblock that is on the front side, that they use to route the big netblock back to me
[15:12:49] <ssi> ubiquity hosting
[15:12:52] <_methods> hmm
[15:12:57] <ssi> it's in telx in downtown atlanta
[15:12:58] <CaptHindsight> that is low cost enough to resell space on
[15:13:02] <ssi> yeah
[15:13:04] <_methods> yeah
[15:13:12] <_methods> i want in lol
[15:13:18] <_methods> you go to freeside?
[15:13:19] <ssi> heheh
[15:13:22] <ssi> naw
[15:13:31] <_methods> you in atlanta?
[15:13:34] <ssi> yeah
[15:13:37] <ssi> a long time ago I wanted to
[15:13:45] <ssi> and then it was like "oh you gotta get sponsored and do work and blah blah"
[15:13:46] <_methods> one day i wanna get down there and check it out
[15:13:50] <ssi> and I said fuck that
[15:13:52] <_methods> oh yeah
[15:13:54] <_methods> no thank you
[15:13:56] <ssi> I have more equipment than everyone else there combined
[15:13:59] <_methods> yeah
[15:13:59] <ssi> they should be begging for me to join
[15:14:12] <_methods> just wondered
[15:14:17] <_methods> looked like a decent space
[15:14:18] <ssi> just seemed culty
[15:14:20] <ssi> or fratty
[15:14:21] <ssi> or something
[15:14:43] <_methods> most of those spaces are full of asperger nut jobs anyways
[15:14:47] <ssi> yeah
[15:14:53] <ssi> and these days, just tons of glue gun kids
[15:14:57] <_methods> omg
[15:15:22] <ssi> don't get me wrong, I've built a few glue guns, and they're handy for what they are
[15:15:32] <ssi> but the freakn glue gun kids treat them like they're the second coming of christ
[15:15:33] <_methods> they're fun i have 2 of em
[15:15:43] <_methods> mine just sit there anymore
[15:15:48] <ssi> yeah mine too
[15:15:57] <ssi> I built a big delta machine that I wanted to get running as a printer
[15:16:06] <ssi> I took the original rostock wood design and made a nice extrusion based one
[15:16:15] <_methods> man i can machine out of uhmw or hdpe something way better way faster
[15:16:16] <ssi> and then the seemecnc guys ripped off my design :
[15:16:17] <ssi> hehe
[15:16:19] <_methods> so why bother
[15:16:37] <ssi> whereabouts are you?
[15:16:45] <_methods> charleston sc
[15:16:49] <ssi> ah ok
[15:17:08] <_methods> dirty south too
[15:17:36] <_methods> nothin but bugs and tacky clothes
[15:17:40] <_methods> just the way i like it
[15:20:33] <_methods> CaptHindsight: http://campus.codeschool.com/courses/discover-drive/intro
[15:20:43] <_methods> hah they even have a course for it
[15:21:32] <Deejay> namd
[15:28:18] <q_p> how to use autoleveler with tb6560 ?
[15:29:03] <SpeedEvil> http://tv.slashdot.org/video/?embed=01b3Jjbjq_5YhB6ipoWGYtORDcJ7w5OO TIG 3D printer
[15:33:39] <ssi> SpeedEvil: this guy doesn't seem smart enough to accomplish anything significant :P
[15:33:48] <JT-Shop> lol
[15:34:02] <SpeedEvil> ssi: I agree
[15:34:17] <SpeedEvil> But attempting shit you're not competant at > bitching
[15:34:28] <ssi> this is true :)
[15:34:42] <SpeedEvil> Succeeding is better than either though :)
[15:34:56] <ssi> I'd love to know what that's like :P
[15:35:28] * SpeedEvil wishes nitrogen was easily usable as a shield gas
[15:35:40] <_methods> it's not?
[15:35:48] <ssi> it's too light I think
[15:35:59] <_methods> we use it all day on laser
[15:36:02] <ssi> argon works well cause it's denser than air, and sinks around your weld area
[15:36:15] <_methods> use it to purge beam path too
[15:37:01] <Loetmichel> ssi: it isnt to light
[15:37:27] <Loetmichel> but it tends to react with the molten metal
[15:37:32] <Loetmichel> it is not iniert
[15:37:33] <Loetmichel> inert
[15:37:37] <ssi> ah
[15:38:27] <_methods> http://en.wikipedia.org/wiki/Inert_gas
[15:38:41] <Loetmichel> and you dont want to have nitrogen in your steel/aluminium welds
[15:38:52] <Loetmichel> makes them brittle iirc
[15:40:06] * JT-Shop can't believe how clean these parts are and how many hours I saved over blasting
[15:40:16] <ssi> JT-Shop: :D
[15:40:31] <SpeedEvil> ssi: helium is very commonly used in welding.
[15:40:41] <SpeedEvil> JT-Shop: electrolysuys?
[15:48:40] <JT-Shop> hcl
[15:50:06] <SpeedEvil> Ah
[15:51:36] <ssi> I ordered one of the shapeoko kits
[15:51:43] <ssi> might be a good base for building a pick'n'place
[15:55:58] <jdh> what are you picking and placing?
[15:56:51] <mozmck> JT-Shop: glad it worked!
[15:58:38] <cpresser> _methods: what materials are you cutting with the laser?
[15:59:21] <cpresser> _methods: and which laser? i am still unsure if i should try nitrogen-air-assist for my 80W Co2-Laser when cutting acrylic or wood
[15:59:53] <SpeedEvil> Air assist is needed for wood
[16:00:03] <SpeedEvil> Makes it much, much bettee
[16:00:06] <SpeedEvil> R
[16:00:15] <JT-Shop> mozmck, thanks it worked great. I just need to refine my part handling a bit
[16:00:29] <Loetmichel> SpeedEvil: at least one should protect the lens vom getting fumes
[16:00:39] <JT-Shop> I can't believe that I'm done with those parts already
[16:00:47] <SpeedEvil> Yeah
[16:01:01] * cpresser has air-assist. but with air, not nitrogen
[16:01:14] <SpeedEvil> For that reason if no other, it doesn't make sense to not use it
[16:01:24] <SpeedEvil> Using nitrogen reduces burning
[16:01:25] <ssi> jdh: for assembling pcbs
[16:02:04] <cpresser> yes, but how much does it reduce the burning? how big is the difference when looking at the finished part? thats what i want to know
[16:02:06] <mozmck> ssi: I have 2 pick and place machines I need to get rid of. panasonic cm62p, fairly small footprint.
[16:02:33] <Loetmichel> even this homemader 80W laser of a friend had air assist for the lens -> http://bambuser.com/v/2270235
[16:02:38] <Loetmichel> (the green hose)
[16:03:10] <ssi> mozmck: what are you looking to get for them
[16:03:28] <Loetmichel> (was a bit scary to see that open system runnung with an 80W co2 tube running and no laser glasses
[16:04:04] <mozmck> ssi: oh, probably $600 each
[16:04:16] <ssi> I can't find any info about them
[16:04:34] <mozmck> tray feeders on both, paper manuals in english and japanese
[16:04:41] <mozmck> schematics.
[16:05:00] <ssi> what's the working area like
[16:05:14] <mozmck> I had one nearly running, but it would jump when jogging with the keyboard at times.
[16:05:14] <ssi> how many reels/trays/whatev
[16:05:22] <ssi> you must be moses mcknight :P
[16:05:29] <_methods> cpresser: this is on a 3200w trumpf laser
[16:05:34] <mozmck> I would have to look again - that's me :)
[16:06:03] <cpresser> _methods: okay... thats another league
[16:06:18] <ssi> mozmck: I might be interested... fetching them might be tricky
[16:06:21] <ssi> mozmck: got any pictures?
[16:06:30] <mozmck> I hate to just leave them sitting. Worst case I'll tear them down and sell parts.
[16:06:31] <_methods> yeah
[16:06:32] <_methods> hehe
[16:07:11] <cpresser> mozmck: i might also be interested in a pick-n-place machine... where are the machines now?
[16:07:18] <mozmck> http://www.mcknight-instruments.com/zenphoto/other/pick-and-place/
[16:07:22] <mozmck> near dallas tx
[16:08:24] <ssi> got an estimate of weight?
[16:08:31] <mozmck> lots of new replacement parts as well.
[16:08:43] <mozmck> heavy - maybe 1000 lbs
[16:08:45] <mozmck> each
[16:08:48] <ssi> ok
[16:09:02] <ssi> is important because I can pull a trailer with my car, but I'm limited to 2000lb
[16:09:09] <ssi> be nice to be able to get both of them on a trailer, but sounds like that's not happening
[16:09:12] <mozmck> oh.
[16:09:23] <ssi> can bring a truck, but car gets 50mpg, truck gets 20
[16:09:24] <ssi> :)
[16:09:43] <mozmck> yeah, that makes a difference.
[16:09:44] <cpresser> damm.. wrong continent for me to pick it up :/
[16:09:56] <ssi> and there's a reasonable chance I might want both
[16:09:57] <mozmck> where are you cpresser?
[16:10:02] <cpresser> europe/germany
[16:10:11] <mozmck> long ways away!
[16:10:37] <mozmck> oh, there are lots of feeders with these - 30 or so I think.
[16:11:03] <ssi> were you intending to convert it to lcnc?
[16:11:10] <mozmck> several sizes of reel and tube feeders.
[16:11:30] <mozmck> I had thought of it if I couldn't get the built in software to work.
[16:11:51] <ssi> looks like it might be a big pain in the ass :P
[16:12:17] <mozmck> Nearly had that working but we wound up using an outside board shop to assemble and I lost incentive and time to play with them.
[16:12:41] <mozmck> Yes, there are *lots* of inputs and all.
[16:13:41] <mozmck> they move fast though, and will place down to 0603 in size.
[16:14:31] <mozmck> video cameras for teaching and fiducial reading
[16:14:38] <ssi> nice
[16:14:57] <ssi> yeah it could be worthwhile... big machine tho
[16:15:31] <mozmck> I have far too many projects and am trying to clear some out
[16:15:36] <ssi> yeah you and me both
[16:15:48] <mozmck> These are not nearly as big as most PnP machines I've seen.
[16:15:59] <ssi> sure, but I'm talking about buildign a little desktop machine
[16:16:11] <mozmck> I see, yes bigger than that.
[16:16:28] <ssi> I'm fairly well out of space for large machines at this point :)
[16:17:02] <ssi> i'll keep it in mind tho
[16:17:34] <mozmck> I know the feeling. I just sold a 14" logan lathe, and have 2 more lathes and a mill I need to get rid of.
[16:17:55] <q_p> mozmck: yo was the guy who made a stepper motor control and upload your project to invertable. com ???
[16:18:07] <mozmck> ok, it will be a little while before I get around to doing much with them.
[16:18:16] <mozmck> q_p: not me.
[16:18:27] <q_p> okay
[16:18:29] <q_p> thx
[16:24:26] <JT-Shop> yuck my siding order is in... now I have to put the siding on the shop and garage
[16:26:16] <jdh> outsource it?
[16:47:28] * JT-Shop is so far ahead today I'm going to take the rest of the day off
[16:55:25] <ssi> 7i75 pin namings are wonky
[16:55:37] <ssi> and I can't find which hm2 pins correspond to the inboard connectors
[16:57:20] <JT-Shop> for the I/O pins?
[16:57:40] <ssi> yeah
[16:57:52] <ssi> I have the 7i75 on the internal connector of the 5i25
[16:58:19] <ssi> and the terminal block labeled IO0 corresponds to hm2's gpio.033
[16:58:26] <ssi> IO2 corresponds to .032
[16:58:32] <ssi> I can't find what IO1 and IO3 correspond to
[16:58:36] <Tom_itx> JT-Shop, your plans will get changed
[16:58:41] <Tom_itx> mine always seem to
[16:58:44] <JT-Shop> you need to look for 7i75 pins not hm2
[16:59:16] <JT-Shop> hm2_5i25.0.7i76.0.0.input-04
[16:59:25] <ssi> 7i75 is a passive protection module
[16:59:36] <JT-Shop> oh
[16:59:44] <JT-Shop> that's different
[16:59:48] <Connor> ssi Which firmware you using ?
[16:59:50] <Tom_itx> if it's just protection it may not show up ata ll
[16:59:56] <ssi> g540x2
[17:00:21] <Connor> Hmm.
[17:00:36] <Connor> it may be treating that as a output...
[17:01:06] <Connor> g540 expects a parport ?
[17:01:18] <ssi> forget g540, it's not a factor
[17:01:22] <Connor> so, it would only have 5 inputs
[17:01:35] <Connor> I understand. But, the 5i25 is EMULATING a parport.
[17:01:58] <ssi> yes, and the7i75 is a 17 io parport protection board
[17:02:11] <ssi> and looks like all the io work except for four, one daughterboard
[17:02:13] <ssi> looking at the manual now
[17:02:27] <Connor> right. with only 5 inputs ?
[17:02:34] <ssi> dude
[17:02:37] <ssi> forget g540
[17:02:41] <ssi> it's not a factor
[17:03:16] <ssi> no
[17:03:21] <ssi> it's hm2... all pins are gpio
[17:03:30] <ssi> don't scream at me if you're ignorant of fact
[17:03:56] <micges> ssi: what's the problem with 7i75?
[17:04:23] <ssi> micges: one of the terminal blocks doesn't respond to inputs... not sure if they're set as out only in hal or what exactly
[17:04:53] <Connor> but, did you not just say you was using the g540x2 firmware ? which would turn the gpio's to specific Inputs and outputs for emulating a parport.
[17:05:02] <ssi> that's not how it works
[17:05:56] <ssi> and the fact that I have thirteen working inputs and four that aren't responding seems to fly in the face of your "theory"
[17:06:06] <JT-Shop> ssi to set a gpio to output you have to setp xxx.is_output 1 in hal somewhere
[17:06:38] <Tom_itx> set the direction and state
[17:06:51] <JT-Shop> General Purpose I/O pins on the board which are not used by a module instance are exported to HAL as full GPIO pins. Full GPIO pins can be configured at run-time to be inputs, outputs, or open drains, and have a HAL interface that exposes this flexibility. I/O pins that are owned by an active module instance are constrained by the requirements of the owning module, and have a restricted HAL interface.
[17:06:53] <ssi> JT-Shop: not doing that explicitly anywhere
[17:07:09] <JT-Shop> might be used by a stepgen or something
[17:07:24] <ssi> I have numstepgens = 5
[17:07:35] <ssi> which should be joints 0-4 plus the chargepump generator
[17:08:00] <ssi> and dmesg shows all p2 pins as gpio except one which is a pwmgen
[17:08:28] <ssi> lemme expliitly set pwmgens=1, that should disable the p2 pwm
[17:10:25] <ssi> but besides this issue, they're numbered oddly
[17:10:41] <JT-Shop> tis true, confusing to be flexible
[17:10:47] <DaViruz> 1,3,5,7,9...?
[17:10:53] <ssi> the connector row opposite the db25 is numbered evens, 0, 2, 4, 6, 8, 10, 12, 14, 16
[17:11:03] <ssi> 0, 2, 4, 6 correspond to 33, 32, 31, 30
[17:11:10] <ssi> 8 is 29, 10 is 27
[17:11:14] <ssi> dafux :)
[17:12:04] <ssi> 12 is 25, 14 is 21
[17:12:12] <ssi> it just gets odder and odder
[17:12:18] <JT-Shop> your confusing me with the facts lol
[17:12:20] <Connor> http://pastebin.com/2DM4rfR6
[17:12:23] <JT-Shop> gotta run
[17:12:39] <ssi> 16 is 17
[17:13:06] <Connor> PinOuts for p2 and p3 for g540x2 firmware
[17:13:30] <ssi> Connor: that shows parport pins to hm2 io number, but not which terminal block they break out to
[17:14:34] <ssi> 1, 3, 5, 7 terminal blocks don't toggle any hm2 io in the 17-33 range
[17:14:44] <ssi> those are the only four that don't work
[17:14:47] <Connor> http://www.mesanet.com/pdf/parallel/7i75man.pdf
[17:14:53] <Connor> page 3
[17:15:08] <Connor> and page 4
[17:15:17] <Connor> and 5
[17:15:32] <ssi> yes, those all exist
[17:15:38] <ssi> still there's no mapping
[17:17:51] <micges> 1 should toggle gpio 18
[17:17:59] <micges> terminal 1*
[17:18:15] <ssi> micges: eh?
[17:18:23] <ssi> gpio18 is terminal 1 on '75?
[17:19:01] <micges> if you connected it to header on 5i25 then yes
[17:19:35] <ssi> none of the 17-33 have .is_output set
[17:20:12] <micges> terminal 0 works?
[17:20:56] <ssi> yeah
[17:20:59] <ssi> I bet it's this cable
[17:21:13] <micges> it toggle gpio 17 ?
[17:21:18] <ssi> no, 0 toggles 33
[17:21:43] <ssi> swapping cables, sec
[17:22:38] <ssi> yeah it's the cable
[17:22:39] <ssi> hah
[17:23:31] <micges> seems cable was crossed
[17:23:42] <ssi> it's more than crossed
[17:23:45] <ssi> it's scrambled ;P
[17:23:53] <micges> heh
[17:24:18] <Connor> Ribbon cable or parport type cable ?
[17:24:19] <micges> no wonder you got confused about pin numbers
[17:24:28] <ssi> no wonder indeed
[17:24:35] <Connor> Could be a laplink type cable..
[17:24:36] <ssi> parport type cable, but obviously not a parport cable
[17:24:42] <ssi> i think it's a leftover TDIF cable
[17:24:48] <ssi> god knows how those are pinned out
[17:24:55] <ssi> i guess imma need to run to microcenter in a bit
[17:26:03] <Deejay> gn8
[18:41:44] <LeelooMinai> I was searching for those weird cables for my digital indicator and most of them were expensive (at least $17,) but at the end I bought two of those: http://www.bgmicro.com/digitalcaliperwithdataoutputport.aspx
[18:42:23] <LeelooMinai> It has both a small-range indicator and the cable I need.
[18:43:24] <LeelooMinai> Now all I have to do is electronics for it - something with multiple channels for this kind of scale.\
[18:48:15] <LeelooMinai> Hmm
[18:49:15] <LeelooMinai> Now when I think about it, the mesa fpga cards could possibly decode those scales, if there's spare room besides the firmware on them.
[18:49:38] <LeelooMinai> They only send clock and one data stream - pretty simple.
[18:50:09] <LeelooMinai> Not sure though if those mesa cards are easy to exntend like that fimware-wise
[18:56:33] <zeeshan|3> LeelooMinai: i hope youre not trying to use those for feedback
[18:56:42] <zeeshan|3> cause the scales have a slow response time
[18:57:20] <LeelooMinai> I am just trying to get data from scales like that in general
[18:58:34] <LeelooMinai> For example, say I want to trace my x-y table with the indicator I have (it's 1μm) - I could automate it completelly and as tedailed map as I want.
[18:58:48] <LeelooMinai> detailed*
[18:58:52] <zeeshan|3> yes
[18:58:57] <zeeshan|3> but hopefully your indicators are accurate!
[18:58:59] <zeeshan|3> to begin with
[18:59:21] <LeelooMinai> This is in fact for now what I am interested it, as I need to come up with some table in next months
[18:59:32] <zeeshan|3> my chinese digital indicator is out by 5 thou over 1"
[19:00:21] <LeelooMinai> zeeshan|3: This matters not really. The one I have is claimed to be one micron, but once I get the system of getting data from those going, I can always get something better, if really needed.
[19:01:08] <zeeshan|3> i met an interesting person today
[19:01:14] <zeeshan|3> he wants to get some welding done
[19:01:27] <zeeshan|3> instead of giving me money, he wants to trade me 100lb of aluminum
[19:01:36] <zeeshan|3> he thought i wouldnt be interested
[19:01:40] <zeeshan|3> im like O_O asap he said that
[19:01:45] * zeeshan|3 likes aluminum
[19:01:47] <zeeshan|3> yum
[19:01:57] <LeelooMinai> I would take it without a blink too:)
[19:02:06] <zeeshan|3> its only like 25$ worth of welding
[19:02:08] <zeeshan|3> too
[19:02:09] <LeelooMinai> If I could/liked welding...
[19:02:29] <zeeshan|3> i don't really like welding either
[19:02:36] <zeeshan|3> but it's needed :p
[19:02:41] <LeelooMinai> It's kind of ugly imho:)
[19:02:50] <zeeshan|3> mig welding, stick welding, yea
[19:02:51] <zeeshan|3> not tig
[19:03:37] <LeelooMinai> Yes, it can be made nice looking and all, but still - it's difficult to have good control over it
[19:03:45] <zeeshan|3> ???
[19:03:49] <zeeshan|3> thats stick welding or mig
[19:03:56] <zeeshan|3> with tig it's highly controllable
[19:04:09] <zeeshan|3> you're controlling the depth of penetration (current) with your foot
[19:04:25] <zeeshan|3> you're controlling the filler rate with your right / left hand filler rod
[19:04:32] <LeelooMinai> It's still a bit of an art - you need a lot of experience to get consistent results.
[19:04:32] <zeeshan|3> and angle of gun
[19:05:00] <zeeshan|3> anyone can do it :P
[19:05:02] <zeeshan|3> its ez
[19:05:02] <LeelooMinai> UNless you have a robot that does that
[19:05:23] <LeelooMinai> Screwing things together is easier though:)
[19:05:36] <zeeshan|3> dirty woman.
[19:05:39] <zeeshan|3> !
[19:05:39] <LeelooMinai> And adjustable
[19:06:28] <zeeshan|3> http://i130.photobucket.com/albums/p252/turbozee84/49522FEC-1A37-49F4-B40D-73EDF2E0D4CA-3548-000003554D2519FC_zps7c5309d8.jpg
[19:06:30] <LeelooMinai> I think I may even have some welder in the basement - but I stay away from it
[19:06:31] <zeeshan|3> with car stuff you need it
[19:07:12] <LeelooMinai> wel,, yes, I realize some things need it. I used to ride MTB marathons - did tons of them, so I know a lot about bikes, frames, etc.
[19:08:13] <LeelooMinai> Though at the later stages of my "career" I had carbon-fibre frame anyways:) But for alu frames, yes, they cannot be screwed together.
[19:08:38] <LeelooMinai> But as I understand "welding" aluminum is not something that can be done easy in the basement
[19:09:03] <zeeshan|3> you jsut need a tig welder that can make an ac wave
[19:13:50] <LeelooMinai> Hmm, nice, they provide full VHDL source for the 5i25 firmware
[19:14:52] <zeeshan|3> damn it
[19:14:57] <zeeshan|3> this stupid iphone 4 doesnt work with my gf's sim
[19:15:03] <zeeshan|3> damn this AWS
[19:22:09] <Jymmm> If you were to chuck up a pen, what drawing would best show backlash?
[19:22:44] <mozmck> maybe a circle?
[19:23:19] <LeelooMinai> zig-zag? :)
[19:24:41] <mozmck> not sure how well that would show it.
[19:25:29] <zeeshan|3> circle is the easiest
[19:25:30] <zeeshan|3> :p
[19:25:33] <mozmck> with a circle I would think you could see some anomalies where the axes reverse direction.
[19:25:34] <LeelooMinai> If you want to see backlash you must have pattern that changes dirrection, so first thing that I imagined is a zig-zag pattern
[19:26:40] <LeelooMinai> Then you can examine the vertices to see if the are "sharp"
[19:28:00] <mozmck> hmm, yes, I guess you would have a little flattening as it took up slack.
[19:32:29] <LeelooMinai> So I read a bit about mesa firmware and it looks pretty good. It's modularized and can be easily resynthesized for custom needs and extended.
[19:33:23] <LeelooMinai> I would probably need some spartan6 dev board to develop for it
[19:34:45] <LeelooMinai> Anyone here have done some customisation to mesa firmware?
[19:36:09] <Tom_itx> bit files
[19:36:10] <Tom_itx> yes
[19:36:27] <Tom_itx> why?
[19:37:01] <LeelooMinai> Just wondering about the experience. Did you just use the mesa card while developing?
[19:37:21] <Tom_itx> all i did was make custom bit files for my boards
[19:37:39] <Tom_itx> then wrote about it
[19:37:51] <LeelooMinai> Ok, but custom how? you did not write any new VHDL?
[19:37:58] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/emc/xilinx/xilinx14_install_index.php
[19:38:43] <Tom_itx> by calling instances of built in mesa functions
[19:38:58] <mozmck> I think PCW or pcw_home has done some customization to mesa firmware ;)
[19:39:04] <LeelooMinai> So what did you customize there?
[19:39:16] <Tom_itx> mozmck, quite a bit i'd say :D
[19:39:39] <Tom_itx> LeelooMinai, changed the function on some pins and added functions for others
[19:39:57] <Tom_itx> different from 'stock' pinouts
[19:40:27] <Tom_itx> i added sserial to my 7i43 so i could use an sserial card with it for one thing
[19:40:37] <LeelooMinai> I see. Do you know if Xilinx software is free for the size of fpga the mesa boards have? I think it's 400k or something like that
[19:40:46] <Tom_itx> it is
[19:41:01] <Tom_itx> not really free... it will eat up your hddd
[19:41:11] <mozmck> and download bandwidth
[19:41:19] <LeelooMinai> Ok, then it looks good. Maybe even someone wrote the code for those digital scales somewhere.
[19:41:36] <Tom_itx> http://www.xilinx.com/support/download/index.html/content/xilinx/en/downloadNav/design-tools.html
[19:41:38] <LeelooMinai> If not, it should not be too difficult to add it.
[19:42:37] <Tom_itx> i didn't follow what you were trying to do but i'm not sure you would need to customize the mesa firmware
[19:42:43] <PCW> Those scales are pretty slow, might be able to do it with the twiddler interface
[19:43:04] <LeelooMinai> Yes, but doing it on fpga is much more elegant
[19:43:53] <PCW> not sure how elegant it is to interface to khz bitstreams with hardware :-)
[19:44:57] <LeelooMinai> It's a stream of data that will be coming in - doing averaging, decoding, etc. should be done on hardware - no need to burden cpu with it
[19:45:08] <PCW> the twiddler interface has a 100 MHz 8 bit processor for bitbanging...
[19:45:34] <LeelooMinai> Ok, maybe I should start with asking what is that twiddler:)
[19:45:45] <LeelooMinai> I thought it's some API
[19:46:22] <PCW> no its a tiny attached processor for low speed flexible I/O
[19:46:28] <jdh> anyone ever use DeoxIT(tm)?
[19:47:30] <LeelooMinai> PCW: I can decode it with any μC, but since I will use that mesa board anyways, it seems nicer to just take advantage of the resources it provides
[19:48:13] <PCW> one of those resources is a prebuilt interface processor
[19:49:08] <PCW> 1K ROM 512 byte RAM 100 Mhz (10 ns/inst)
[19:49:21] <LeelooMinai> The data coming from those scales is very simple - using some kind of generalized processor for it seems like overkill.
[19:49:59] <mozmck> isn't that what an fpga is? ;)
[19:50:16] <Tom_itx> read it into an avr
[19:50:25] <PCW> Well then a shift register (with lots of digital filtering)
[19:50:29] <LeelooMinai> But it's already sitting there on the mesa card with spare cells
[19:57:06] <PCW> I still use ISE
[19:57:43] <mozmck> I don't see a webpack version - is that only for Vivado now?
[19:57:47] <LeelooMinai> PCW, btw, do you know some cheap spartan6 dev board?
[19:57:52] <PCW> haven't played with Vivado
[19:58:05] <LeelooMinai> I am googling right now, but so far, pretty expensive
[19:58:32] <PCW> there are some $49 ones (and our 7I90 is $59)
[19:59:02] <LeelooMinai> Hmm, wait a sec... What do you mean "ours" - are you some mesa guy? :)
[19:59:15] <Tom_itx> he's THE mesa guy
[19:59:46] <LeelooMinai> O... ok, it just sounded weird when he wrote "ours":)
[19:59:50] <PCW> if you have a JTAG cable, you can devel on a 5I25
[20:00:16] <LeelooMinai> PCW: Yes, though it would have to sit in the pcie slot, right?
[20:00:53] <Tom_itx> With the ISE Design Suite 14.7 release back in October of 2013, ISE has moved into the sustaining phase of its product life cycle.
[20:00:56] <Tom_itx> mmm
[20:01:17] <Tom_itx> looks like you better learn Vivado
[20:01:37] <LeelooMinai> "sustaining phase"... that sound like keeping somone on life support
[20:01:39] <PCW> a 6I25 is possible to use without JTAG (since you can download a empty FPGA)
[20:02:31] <LeelooMinai> PCW, So i guess you may be even the person that wrote that VHDL code I just was looking at?
[20:02:48] <LeelooMinai> Ok, you are
[20:02:54] <Tom_itx> :)
[20:02:54] <LeelooMinai> Peter C Wallace
[20:03:06] <LeelooMinai> Ok, that was funny
[20:03:09] <PCW> Yep
[20:03:11] <zeeshan|3> pcw you're not related to kirk wallace are you
[20:03:19] <Jymmm> PCW: whats the eth one?
[20:03:36] <PCW> well maybe very distantly....
[20:03:48] <Jymmm> By 3000 miles
[20:03:52] <zeeshan|3> haha
[20:04:02] <LeelooMinai> PCW, ok, so you probably know this - with normal firmware, is there a lot of cells left on those mesa cards?
[20:04:07] <zeeshan|3> kirk wallace's code is what i based my modbus driver on
[20:04:26] <Jymmm> zeeshan|3: PCW Is your father!
[20:04:28] <PCW> nah Kirks in cafilornia
[20:04:50] <Jymmm> is he?
[20:04:56] <zeeshan|3> Jymmm: how will you kill me today?
[20:04:59] <zeeshan|3> :]
[20:05:07] <Jymmm> zeeshan|3: softly in your sleep
[20:05:12] <zeeshan|3> haha
[20:05:41] <PCW> iLeelooMinai: Depends on the config but most are only about 1/2 full
[20:05:53] <Jymmm> zeeshan|3: Sorry, poison is reserved for girly murders.
[20:05:53] <LeelooMinai> A, so no worries
[20:06:23] <LeelooMinai> PCW: Did you ever think of adding a module for digital scales to the firmware? Seems like it could be common use, no?
[20:06:43] <Jymmm> glass scales?
[20:07:21] <LeelooMinai> Well, any scales. I am not sure, but aren't people using those in some production environments?
[20:07:46] <Jymmm> iirc they can't be used for speed
[20:07:49] <PCW> machine scales are quadrature
[20:07:54] <LeelooMinai> I mean I saw some DRO boards on many machines
[20:08:00] <PCW> or SSI or BISS ec
[20:08:07] <zeeshan|3> i just explained this earlier
[20:08:08] <zeeshan|3> theyre too slow
[20:08:48] <LeelooMinai> Well, depends for what purpose. IN my example I would like to map x-y table - no need for super-fast data there.
[20:09:04] <LeelooMinai> Or maybe use it for homing
[20:09:07] <LeelooMinai> Things like that
[20:09:11] <PCW> Yeah not useful for control but maybe handy probe type use
[20:09:49] <PCW> also some need funny business to start
[20:10:13] <Jymmm> PCW: pimping? child labor? clown college?
[20:10:19] <zeeshan|3> ive been using a lot of image based distancing software
[20:10:23] <zeeshan|3> like argus and aramis from gom
[20:10:27] <zeeshan|3> shit's pretty precise
[20:10:53] <LeelooMinai> Image based like from what... a camera?
[20:10:54] <zeeshan|3> i wonder if can be integrated with cnc
[20:10:58] <zeeshan|3> yea
[20:11:01] <zeeshan|3> ccd cams
[20:11:09] <LeelooMinai> I wonder how can it be precise...
[20:11:42] <LeelooMinai> Or you mean +/- 1cm? :)
[20:12:59] <zeeshan|3> no
[20:14:05] <zeeshan|3> http://en.wikipedia.org/wiki/Photogrammetry
[20:14:07] <zeeshan|3> uses that
[20:14:37] <zeeshan|3> i've seen resolutions of 0.05mm
[20:14:41] <zeeshan|3> depending on the camera and lighting
[20:15:45] <LeelooMinai> Semms like something requireing some brutal processing power
[20:15:46] <XXCoder2> heys
[20:16:05] <zeeshan|3> which isn't a big deal days with the computers we have
[20:18:20] <Tom_itx> either takes time or power
[20:20:48] <jdh> and time is money to a guy like me.
[20:21:00] <zeeshan|3> jdh shush
[20:21:07] <zeeshan|3> you spend 90% time on irc
[20:21:22] <jdh> only when I'm supposed to be working.
[20:21:32] <jdh> and it was a movie quote anyway.
[20:22:11] <Jymmm> zeeshan|3: But in the other window, jdh is doing internet video "dating"
[20:22:16] <zeeshan|3> haha
[20:22:24] <zeeshan|3> http://i.imgur.com/KrN99JM.jpg
[20:22:25] <Jymmm> zeeshan|3: ... @ $10/minute
[20:22:30] <Tom_itx> Jymmm knows these things...
[20:22:42] <zeeshan|3> photogrammetry ^|
[20:22:43] <Jymmm> Tom_itx: Damn right, I get 10%
[20:23:11] <jdh> that's way too clean
[20:23:24] <Jymmm> jdh: Get back to work biotch! you have 200 dates to go before midnught!
[20:24:24] <Tom_itx> so Jymmm did you get another laser module?
[20:24:38] <RyanS> photogrammetry! I was looking at that ages ago for 3-D modelling
[20:24:47] <Jymmm> Tom_itx: "module" lol, you make it sound like it plugs into an arduino =)
[20:24:59] <RyanS> 0.05mm!
[20:25:12] <Tom_itx> it doesn't?
[20:25:25] <Jymmm> Tom_itx: It's 25 lbs
[20:25:26] <zeeshan|3> ryan you just need the right lense
[20:25:30] <zeeshan|3> and ccd camera
[20:25:34] <XXCoder2> WTF? http://www.iflscience.com/technology/automatic-sperm-extractor-introduced-chinese-hospital
[20:25:45] <RyanS> can you do it with a good SLR?
[20:25:49] <zeeshan|3> no
[20:25:59] <zeeshan|3> slr's use tiny ccds
[20:26:21] <zeeshan|3> thats the main problem with them
[20:26:30] <Jymmm> Tom_itx: got a replacement one today, it's even more off.
[20:26:36] <zeeshan|3> you need the right lense, and ccd is proportional to the area you're looking at
[20:26:48] <RyanS> Some of them are quite big if you get full frame
[20:27:01] <zeeshan|3> like this 0.05mm i speak of is only over a 3"x3"x3" volume
[20:27:20] <zeeshan|3> but for us that's acceptable cause we study necking behaviour in sheets
[20:27:30] <RyanS> hmm suppose it's not really machining accuracy
[20:27:48] <zeeshan|3> yes, but i was thinking it would make hell of a way to scan something
[20:28:06] <zeeshan|3> and re-print using 3d printer
[20:28:48] <RyanS> I was under the impression that photogrammetry was used mainly for surveying and forensic science
[20:29:09] <RyanS> Reconstructing scenes
[20:29:21] <zeeshan|3> lots of applications
[20:29:26] <zeeshan|3> we use it for strain measurement
[20:30:10] <zeeshan|3> http://alacron.com/clientuploads/directory/Cameras/VDS%20VOSSKUELER/ccd-1300_data.pdf
[20:30:12] <zeeshan|3> we use those
[20:30:45] <zeeshan|3> 0.0002"x0.0002" pixels
[20:31:16] <RyanS> I wanted to do it to buildings for 3-D models, actually I and try the trial version of some software. You just take multiple photos of building and can create a 3-D model of it
[20:33:45] <zeeshan|3> thatd be a nice thing to be able to do
[20:33:54] <RyanS> So the sensor on that camera is about 9 x 7 mm, so how big is the sensor on an SLR?
[20:35:02] <zeeshan|3> arent most slr cmos sensors?
[20:35:16] <RyanS> Actually, I think so
[20:35:36] <zeeshan|3> i could have sworn ive seen ccd slr
[20:35:36] <zeeshan|3> though
[20:35:40] <zeeshan|3> google isnt showing me anything
[20:36:19] <RyanS> Or is the sensor on that CCD 16mm?
[20:36:33] <RyanS> 2/3"
[20:36:34] <zeeshan|3> says 8.25mm x 6.60 mm
[20:37:23] <zeeshan|3> http://imaging.nikon.com/lineup/dslr/d3000/spec.htm
[20:37:26] <RyanS> 2/3" I guess is a nominal dimensions
[20:37:33] <zeeshan|3> d3000 is 23.6x15.8 mm!
[20:38:31] <zeeshan|3> i think im calculating only 0.006" pixels though
[20:39:07] <RyanS> try the top of the range camera http://imaging.nikon.com/lineup/dslr/d4/spec.htm
[20:39:14] <RyanS> 36 x 23
[20:40:07] <zeeshan|3> 0.007" pixel size
[20:41:03] <RyanS> So what does that mean, not as high resolution is that CCD?
[20:41:56] <zeeshan|3> your pixel size has to be smaller than what youre trying to measuring
[20:42:18] <zeeshan|3> like if youre trying to measure 0.001" dots
[20:42:26] <zeeshan|3> you cant do that with a 0.007" square pixel
[20:43:14] <SpeedEvil> That's not strictly true.
[20:43:28] <SpeedEvil> Appropriate lenses can magnify
[20:44:22] <zeeshan|3> i'd think at the cost of viewing area?
[20:44:45] <zeeshan|3> like if you're trying to measure a 0.001" dot with a 0.007" square pixel
[20:45:04] <zeeshan|3> actually nm
[20:45:07] <zeeshan|3> if you magnify it right
[20:45:13] <zeeshan|3> it'd fit within the 0.007" pixel
[20:46:26] <zeeshan|3> hopefully the lense doesn't cause distortion!
[20:47:22] <RyanS> Shouldn't you be thinking of the resolution of the actual image output 'effective pixels'?
[20:47:51] * zeeshan|3 isnt an expert
[20:47:55] <zeeshan|3> i just know a little bit :P
[20:48:09] <RyanS> It's more than me
[20:48:11] <LeelooMinai> Hmm, I found pretty cheap dev board for same (I think) spartan6 as on the mesa board: http://www.aliexpress.com/item/LCD1602-xilinx-fpga-development-board-spartan6-xilinx-spartan-6-xilinx-board-xilinx-kit-xc6slx9-tqg144/1723531478.html
[20:48:18] <LeelooMinai> Chinese to the rescue again
[20:48:43] <zeeshan|3> LeelooMinai: you really hate supporting the north americans?
[20:49:27] <LeelooMinai> zeeshan|3: I am glad to support them - if I was rich:)
[20:49:47] <zeeshan|3> can't wait till the gas priceses hit 3$/L
[20:50:00] <zeeshan|3> globalization will slow down
[20:50:04] <zeeshan|3> :]
[20:50:22] <RyanS> What a load of wank http://imaging.nikon.com/lineup/dslr/df/
[20:51:25] <RyanS> "The large mechanical dials on the top deck are carved from solid metal in order to allow more direct and purposeful exposure control." hahaha carved
[20:51:50] <zeeshan|3> haha
[20:52:06] <zeeshan|3> i love marketing:D
[20:52:10] <RyanS> You mean machined in a Chinese factory for two cents each
[20:52:36] <zeeshan|3> brb
[20:53:04] <RyanS> They are trying to appeal to the hipster retro market
[20:53:07] <LeelooMinai> I guess that was supposed to be apealing to non-tech oriented photographers
[20:54:00] <RyanS> Both my parents are obsessed with photography and, do you have any idea what that's like to live with :)
[20:54:25] <LeelooMinai> Could be worse - having parents-audiphiles
[20:54:34] <LeelooMinai> audio*
[20:55:23] <jdh> could be worse - having parents pedophiles
[20:56:50] <RyanS> "I have to take a photo of that, wait the camera batteries and, f-stop, iso, oh no, the macro lens I need to put on a 50 mm, and the bird just flew away"
[21:04:14] <XXCoder2> RyanS: there is worse ones. http://www.iflscience.com/technology/automatic-sperm-extractor-introduced-chinese-hospital
[21:05:10] <RyanS> temperature!
[21:05:36] <RyanS> How do they sterilise it
[21:05:58] <XXCoder2> probably removable rubber covers but dunno either
[21:06:55] <RyanS> It's going to slow onthe video
[21:07:07] <XXCoder2> so you experenced it eh
[21:07:14] <RyanS> I wonder if it plays porn on the screen
[21:07:39] <RyanS> It does!
[21:10:36] <RyanS> It looks painful actually
[21:10:47] <XXCoder2> no clue
[21:16:01] <SpeedEvil> One method involves basically a taser
[21:17:59] <SpeedEvil> http://medical-dictionary.thefreedictionary.com/Electro-ejaculation
[21:18:09] <XXCoder2> noose, lube tissues, and fake sucide note. :P
[21:18:34] <RyanS> Michael Hutchence
[21:19:16] * SpeedEvil decides not to link the youtube video.
[21:19:48] <RyanS> Would you trust these cutters? http://www.ctctools.biz/servlet/the-520/TiAlN-Coated-Tungsten-Micrograin/Detail
[21:22:15] <XXCoder2> I was talking about David Carradine
[21:22:23] <XXCoder2> he forgot fake sucide note though :P
[21:22:52] <zeeshan|3> SpeedEvil: i must try this method
[21:22:56] <XXCoder2> interesting http://www.ranker.com/list/famous-people-who-died-of-erotic-asphyxiation/reference
[21:23:38] <zeeshan|3> RyanS: those look nice
[21:24:52] <RyanS> Although I guess they don't require the tolerance of something like reamers
[21:27:18] <zeeshan|3> depends, if youre using them in a cnc application
[21:27:52] <zeeshan|3> i was using the school cnc mill to make some recessed pockets where a certain component registered against
[21:28:09] <zeeshan|3> i wrote the program right, yet the pockets were coming out too small
[21:28:33] <zeeshan|3> it ended up being that the end mill i was using was a 'regrind' so it wasn't 0.500" it was 0.498"
[21:28:51] <zeeshan|3> redid the tool offset, and it worked out :P
[21:29:07] <RyanS> I think a slot drill works better. However, I
[21:29:13] <RyanS> Apparently
[21:36:06] <RyanS> are carbide endMills easy to break or not these days?
[21:37:47] <Tom_itx> carbide is still brittle
[21:42:02] <XXCoder2> interesting https://www.youtube.com/watch?v=gKK-D5UiMMI
[22:14:40] <os1r1s> Tom_itx: You still around?
[22:18:52] <XXCoder2> wow
[22:19:04] <XXCoder2> guys using his unfinished lathe to make lathe parts
[22:20:08] <ssi> I miss all the fun stuff
[23:54:05] <ssi> k now I'm getting somewheres
