[00:34:31] <Cromaglious_> sitting here making plans for a 32"x24"x12" wood table using 608zz bearings and angle iron rails
[00:35:39] <Cromaglious_> on top of plans for some oilers for my lathe. using 1" borosilicate (pyrex) test tubes
[01:07:45] <archivist> "angle iron rails" you dont want a smooth running machine?
[02:06:03] <zeeshan> hi
[02:07:54] <archivist_herron> up late again!
[02:08:03] <zeeshan> yes been working on the bronze handles
[02:08:11] <zeeshan> they are being a pain
[02:08:28] <zeeshan> they are like 1.3" diameter , 5.5" stickout from chuck
[02:08:33] <zeeshan> i get chatter
[02:08:46] <zeeshan> i feel like mastercam is outputting retarded g-code
[02:09:03] <archivist_herron> use a centre
[02:09:07] <zeeshan> i cant
[02:09:38] <zeeshan> http://i.imgur.com/WzDOPqK.png
[02:09:41] <zeeshan> the outer 2 guys
[02:11:04] <archivist_herron> are your tools sharp enough and the right geometry for the metal
[02:11:13] <zeeshan> i noticed a chip
[02:11:15] <zeeshan> on the insert
[02:11:18] <zeeshan> ill try tomorrow again
[02:11:33] <archivist_herron> and are you spinning fast enough
[02:11:44] <zeeshan> im doing 400 sfm
[02:13:24] <zeeshan> found the issue
[02:13:27] <zeeshan> it is mastercam
[02:13:40] <zeeshan> its going from .008 ipr
[02:13:45] <zeeshan> to .003 when its plunging a bit
[02:13:45] <zeeshan> ..
[02:23:35] <Jymmm> Has anyone seen an all steel SLIM auto center punch?
[02:27:38] <zeeshan> no
[02:27:43] <zeeshan> but today i drilled out a tap
[02:27:46] <zeeshan> with a carbide drill
[02:27:51] <zeeshan> worked out suprisngly well!
[02:29:29] <Deejay> moin
[03:32:35] <Tom_itx> zeeshan, don't plunge at .008"
[03:32:51] <zeeshan> why
[03:32:55] <zeeshan> its more stable now
[03:32:56] <Tom_itx> it's common to half the speed on ramp or plunge
[03:33:06] <zeeshan> yes but i think its sticking out too much
[03:33:07] <Tom_itx> especially ramp
[03:33:08] <zeeshan> so it flexes
[03:33:14] <zeeshan> and then releases
[03:33:19] <zeeshan> under more pressure it should keep flexed
[03:33:22] <Tom_itx> so shorten it
[03:33:22] <zeeshan> rather than going back and forth
[03:33:25] <zeeshan> i cant
[03:33:29] <zeeshan> i would have, if i could
[03:33:52] <zeeshan> its okay, only 2 more to go
[03:33:56] <zeeshan> will do em tomorrow :)
[03:34:13] <zeeshan> they turned out pretty sexy
[03:34:15] <zeeshan> i like bronze
[03:34:16] <Tom_itx> tomorrow is already here
[03:34:26] <zeeshan> tonight :)
[03:34:27] <Tom_itx> why?
[03:34:33] <zeeshan> the color of it
[03:34:34] <zeeshan> its nice
[03:34:37] <Tom_itx> yeah
[03:34:45] <zeeshan> its not orange like copper
[03:34:49] <zeeshan> its like goldenish orange
[03:34:50] <zeeshan> i like
[03:34:50] <Tom_itx> copperish yellow
[03:34:53] <zeeshan> yes
[03:35:02] <Tom_itx> brass is more yellow
[03:35:06] <zeeshan> and chips break pretty much at any feed rate
[03:35:38] <Tom_itx> wired up my 2nd asrock board last night
[03:35:45] <zeeshan> for what
[03:35:49] <Tom_itx> the mill
[03:35:55] <zeeshan> nice :D
[03:36:01] <Tom_itx> i'm gonna keep win7 on the other one i think
[03:36:05] <zeeshan> hey tom have you done engraving
[03:36:07] <zeeshan> with your mill
[03:36:12] <Tom_itx> one mini atx and one itx
[03:36:18] <Tom_itx> a little
[03:36:23] <zeeshan> wait your mill is doing to have 2 motherboards?
[03:36:28] <zeeshan> doing =going
[03:36:35] <Tom_itx> no
[03:38:09] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/pendant/pendant1.jpg
[03:38:11] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/pendant/engrave1.jpg
[03:38:21] <zeeshan> wow thats pretty good
[03:38:31] <zeeshan> what kind of tool bit did you use
[03:38:48] <Tom_itx> carbide half round engraving bit
[03:39:06] <zeeshan> http://www.endmill.com/images/tools/BLANK_HR_CONICAL.jpg
[03:39:08] <zeeshan> like this?
[03:39:59] <zeeshan> im gonna have to try to shop for some tomorrow
[03:43:30] <Tom_itx> http://www.ebay.com/sch/i.html?_odkw=halfround+engraving+bit&_from=R40&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR6.TRC2.A0.H0.Xengraving+bits.TRS0&_nkw=engraving+bits&_sacat=0

[03:43:37] <zeeshan> i need them tomorrow :(
[03:43:44] <Tom_itx> iirc i got 60 deg
[03:43:45] <zeeshan> id like to get this job done for tomorrow
[03:43:48] <Tom_itx> i forget for sure
[03:43:50] <zeeshan> i got another one getting dropped off tommo
[03:44:11] <zeeshan> my spot drill that i was planning to use
[03:44:13] <zeeshan> is too big
[03:44:29] <Tom_itx> don't use a spot drill, they turn out like crap
[03:44:45] <zeeshan> so since these tools are tiny
[03:44:54] <zeeshan> think ill be okay at 3150 rpm
[03:45:00] <zeeshan> i know a lot of these tools want to run faster
[03:45:58] <Tom_itx> i ran mine around 3k rpm
[03:46:06] <Tom_itx> since that's all the spindle would do
[03:46:13] <zeeshan> okay thats reassuring!
[03:46:14] <zeeshan> good!
[03:46:36] <Tom_itx> just think of it as a .040" diameter tool when programming
[03:46:59] <Tom_itx> i'd have to check the depth i ran but that sounds about right on the deeper part
[03:47:00] <zeeshan> lol
[03:47:04] <zeeshan> that means it needs to run at 20000 rpm
[03:47:09] <zeeshan> to hit 200 sfm in aluminum
[03:47:24] <Tom_itx> i think the other was around .025 or so
[03:47:33] <zeeshan> 1 thou chip load?
[03:47:35] <Tom_itx> no, you just run slow feed
[03:47:42] <Tom_itx> i'd have to look
[03:48:13] <zeeshan> i have some HSS rounds
[03:48:15] <Tom_itx> i ran it pretty slow or you'll chip the tip off
[03:48:16] <zeeshan> 1/4" and 1/8"
[03:48:24] <zeeshan> from my understanding
[03:48:27] <zeeshan> you just need to grind a flat
[03:48:37] <Tom_itx> it has a tiny flat
[03:48:56] <zeeshan> i dont know if my grinding skills will output a taper correctly :P
[03:48:57] <Tom_itx> maybe .001-.002"
[03:49:03] <zeeshan> lol thats tiny
[03:49:04] <Tom_itx> no, i tried
[03:49:15] <Tom_itx> i bought them and things went alot better
[03:49:51] <zeeshan> could a carbide burr work?
[03:49:55] <zeeshan> im just trying to keep options open
[03:50:00] <zeeshan> just incase i cant find any tomorrow
[03:50:09] <Tom_itx> you want a nice tip
[03:51:16] <Tom_itx> S3000 F5 but i don't think i ran it at 5 ipm
[03:51:36] <Tom_itx> i'm sure i overwrode that
[03:52:02] <zeeshan> 3000 @ 5ipm is around .002 chip load
[03:52:04] <zeeshan> that sounds right
[03:52:19] <zeeshan> i imagine .001 - 0.002 being okay
[03:53:11] <zeeshan> okay its bed time
[03:53:16] <zeeshan> cant keep eyes open :-)
[03:53:29] <Tom_itx> z -.010 is what the cad says
[03:53:30] <zeeshan> need to get like 3 hours of sleep before class
[03:53:34] <zeeshan> ah
[03:53:37] <Tom_itx> i think i went deeper though
[03:53:39] <zeeshan> i need to aim for .005
[03:53:40] <zeeshan> er
[03:53:42] <zeeshan> 0.05
[03:53:42] <Tom_itx> test it first
[03:53:50] <zeeshan> yea ill try it on scrap aluminum
[03:54:03] <zeeshan> cya!
[03:54:06] <Tom_itx> but my table wasn't perfectly flat either and i didn't want thin text on part of it
[03:54:24] <Tom_itx> you'll find a depth that looks best
[03:54:33] <Tom_itx> i like the deeper part on mine best
[03:54:44] <Tom_itx> then i went over it with black paint to make it stand out
[04:14:22] <Cromaglious_> hmm was just thinking to grind a decent single flute.. chuck it up in a 4 jaw and mount a angle grinder off the compound on a lathe set the round a bit off center and grind the taper. grind the flat after that with the less ground side as the rightside of the flat, then you end up with a clockwise cutting bit
[04:43:28] <XXCoder> heys
[04:44:12] <XXCoder> zeeshan: "handes" rigggght lol
[04:44:14] <XXCoder> JK
[09:23:58] <bensbenz> Hi, anyone here that could answer a few questions for a linuxcnc newbie?
[09:31:04] <SpeedEvil> Maybe
[09:31:33] <bensbenz> Hi, I am currently running a lathe with Mach3.
[09:31:42] <archivist_herron> ew
[09:31:58] <bensbenz> I have found too many bugs in spindle control so I want to switch
[09:32:04] <bensbenz> yes right it sucks
[09:32:18] <bensbenz> I would like a setup that acutally works with CSS
[09:33:05] <bensbenz> I booted up from the USB installed, got most things working ok, but it seems linuxCNC needs and encoder on the spindle?
[09:33:32] <bensbenz> I just have a simple disk and an index pulse board.
[09:33:52] <SpeedEvil> you get one pulse per rev?
[09:34:14] <bensbenz> Yes sir
[09:35:33] <bensbenz> I was able to figure out adding a tach to the screen, but the RPM just all over the place.
[09:35:42] <pcw_home> 1 PPR will never be very good
[09:37:20] <bensbenz> I was able to thread no problems before and get a constant reading, but seems like everyone says for linuxcnc you an encoder with at least 2 inputs
[09:38:01] <bensbenz> Thats fine, I just have no idea where to start, and if I would also need some other interface board, or if its something that I just wire directly to my BOB>
[09:50:39] <pcw_home> if you have good speed control 1 PPR might be OK but you are entirely dependent on the speed control accuracy between pulses
[09:51:55] <SpeedEvil> bensbenz: how is the speed control done?
[09:52:03] <zeeshan> wow not a single place
[09:52:05] <zeeshan> carries engraving bits
[09:52:05] <pcw_home> so especially if you have variable loading and imperfect speed control 1PPR is not good
[09:52:17] <zeeshan> i guess no one eengraves?!
[09:52:18] <zeeshan> (locally)
[09:52:36] <bensbenz> Ok, I think I could build something like this: http://www.model-engineer.co.uk/forums/postings.asp?th=66095
[09:52:48] <zeeshan> bensbenz: what kind of lathe?
[09:53:21] <SpeedEvil> bensbenz: basically - yes - DIY encoders can be quite simple.
[09:53:22] <bensbenz> its a grizzly 10x22 g0602
[09:53:30] <SpeedEvil> bensbenz: Do you have any gear attached to the main shaft?
[09:53:41] <bensbenz> no its all pulleys
[09:53:52] <zeeshan> i have a 10x36, similar to it
[09:53:55] <zeeshan> i made a hub for mine
[09:54:01] <zeeshan> and attached the timing gear to it
[09:54:10] <ssi> morn
[09:54:15] <SpeedEvil> bensbenz: toothed pulleys?
[09:54:17] <zeeshan> hi
[09:54:30] <bensbenz> I wish, no they a vbelts
[09:54:57] <SpeedEvil> (suggestion was to place metal sensors at the cogs offset to form a sensor)
[09:55:08] <SpeedEvil> any gear of any sort attached to the pulley will work
[09:55:41] <bensbenz> Ok, I only use one of the grooves on the pulley now because of the VFD
[09:56:47] <bensbenz> I guess I could machine off part of the pulley to make room, or just make a disk, I have a cnc mill so it wouldnt be too hard
[09:58:05] <bensbenz> If I used opto sensors, would I just hook them up to the BOB directly?
[09:58:33] <zeeshan> depends on the sensor
[09:58:36] <bensbenz> I have a index pulse board from cnc4pc now
[09:58:42] <zeeshan> ithats what i use
[09:58:51] <zeeshan> those you could connect em directly to the bob
[09:58:51] <bensbenz> do you use more than one?
[09:58:55] <zeeshan> but they're overpriced :P
[09:58:59] <zeeshan> yea, 2 of them
[09:59:24] <bensbenz> ok, so I could get another
[09:59:54] <bensbenz> I live very close to automationtechnology so I could just go pick one up there, I think they carry most of cnc4pc's stuff
[10:00:20] <bensbenz> so basically, get another one of those and make a new disk with more slots?
[10:00:29] <zeeshan> http://turbozee84.altervista.org/machines/lathe/controller.html
[10:00:59] <bensbenz> oh cool, is that one yours?
[10:01:06] <zeeshan> yes
[10:01:58] <bensbenz> how many slots does your disk have?
[10:04:15] <zeeshan> 70 i think
[10:05:18] <bensbenz> Cool, I think I will give that a try. Seems like the quickest way to sort my problem. I assume your threading and doing CSS no problems?
[10:05:35] <zeeshan> yes all you need is 2 sensors for that
[10:05:46] <bensbenz> Oh, is one slot bigger than the rest?
[10:05:49] <zeeshan> yes
[10:05:53] <zeeshan> you need one index slot
[10:05:58] <zeeshan> one sensor that picks it up
[10:06:13] <zeeshan> and then another sensor that picks up 69+1 slot
[10:06:19] <zeeshan> 1 being the index slot
[10:06:42] <ssi> here's mine
[10:06:42] <ssi> https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xaf1/v/t1.0-9/205204_655375525742_5631970_n.jpg?oh=47ac27df8c9f340f8ce7a6d3ca508ade&oe=55A4F321&__gda__=1440475871_bf1a33075ecea292a0a73501d951edb7
[10:06:46] <bensbenz> So the one sensor is set so that it only sees the 1 larger slot
[10:06:50] <zeeshan> yea
[10:07:02] <zeeshan> ssi youre hardcore
[10:07:04] <zeeshan> is that your lathe
[10:07:07] <ssi> yes
[10:07:08] <zeeshan> why do you have full quadrature!
[10:07:08] <zeeshan> :P
[10:07:15] <ssi> cause I'm a fuckin baws
[10:07:18] <bensbenz> lol
[10:07:18] <zeeshan> lol
[10:07:42] <zeeshan> you can rigid tap on the lathe! :D
[10:07:46] <ssi> I can indeed
[10:07:54] <zeeshan> dude i blew up a 3/8-16 tap yesterday
[10:07:55] <ssi> both lathes rigid tap just fine
[10:07:57] <bensbenz> my lathe doesnt have the balls for that
[10:08:08] <zeeshan> i made full recovery
[10:08:14] <zeeshan> drilled it out!
[10:08:22] <ssi> hah nice
[10:08:23] <ssi> hate that
[10:08:27] <zeeshan> carbide ate through it
[10:08:28] <zeeshan> slowly
[10:08:35] <zeeshan> using a carbide dril bit
[10:08:54] <_methods> until you break a carbide tap lol
[10:09:10] <tiwake> oh yeah
[10:09:20] <_methods> edm time
[10:09:21] <bensbenz> ssi, are you using some sort of board to connect the sensors to before they are connected to the PC?
[10:09:21] <_methods> lol
[10:09:23] <tiwake> who uses a carbide tap?
[10:09:28] <_methods> i use them
[10:09:42] <tiwake> don't think I've ever talked to anyone who uses them
[10:09:42] <ssi> bensbenz: yeah I run them through some schmidt triggers to clean up the edges, and then into mesa inputs
[10:09:57] <_methods> coolant thru carbide taps
[10:09:58] <tiwake> _methods: use them on what?
[10:10:03] <_methods> whatever
[10:10:07] <_methods> depends on the job
[10:10:09] <bensbenz> ah ok, i dont have the mesa card
[10:10:27] <bensbenz> i cant rigid tap with this lathe anyways
[10:10:30] <_methods> mainly high production stainless
[10:10:56] <tiwake> hmm
[10:11:32] <tiwake> I don't have any machines that rigid tap
[10:11:43] <_methods> hehe i got a pile of "dead" ones in my toolbox i take from work
[10:11:50] <_methods> i won't use them in a real job
[10:11:56] <_methods> but they are fine for using at my house
[10:12:08] <_methods> exocarb vx taps
[10:12:15] <zeeshan> hey guys help me find a local supplier
[10:12:19] <zeeshan> that will carry engraving bits
[10:12:35] <zeeshan> one place carries only 6 flute 1/4" shank bits for wood
[10:12:38] <zeeshan> but its carbide
[10:13:06] <tiwake> why would you not want carbide engraver?
[10:13:11] <_methods> ssi: i guess my boss is never going to quote your part
[10:13:17] <_methods> i dont' know wtf he's doing
[10:13:32] <ssi> lol
[10:14:36] <_methods> kinda pissin me off it's a good job
[10:18:10] <bensbenz> well guys, I was on the fence about converting but now I have a plan. thanks for the help!
[10:18:25] <_methods> right on
[10:18:33] <bensbenz> I am sure I will be back on bugging you with more questions, lol
[10:18:53] <bensbenz> Havent used IRC in like 10 years.
[10:18:54] <tiwake> why not stay?
[10:18:58] <_methods> haha
[10:19:11] <bensbenz> I can, not running mIRC, does that still exist?
[10:19:18] <tiwake> ha yes
[10:19:23] <_methods> i believe so
[10:19:25] <tiwake> I like hexchat myself
[10:19:26] <bensbenz> just running the web based one
[10:19:29] <zeeshan> i use kvirc
[10:19:37] <_methods> irssi
[10:19:49] <zeeshan> whats with you console irc'ers
[10:19:50] <zeeshan> haha
[10:19:55] <bensbenz> lol mirc brings me back to the team fortress clan days
[10:19:58] <_methods> irc like a man
[10:20:03] <zeeshan> baws
[10:20:09] <_methods> you gui pussies
[10:20:14] <zeeshan> lol
[10:20:20] <tiwake> but I like clicking on shiny things!
[10:20:22] <zeeshan> technically you can run linuxcnc off console
[10:20:31] <zeeshan> make a console itnerface for it
[10:20:34] <zeeshan> so you can ssh
[10:21:05] <bensbenz> what distro you guys running linuxcnc on?
[10:21:11] <_methods> debian
[10:21:17] <zeeshan> one machina is running ubuntu
[10:21:19] <zeeshan> other is deb
[10:21:27] <_methods> yeah i got one on ubuntu too
[10:21:40] <bensbenz> I actually had a problem with the bootable usb install, after a reboot no X
[10:21:50] <_methods> were you on hdmi monitor?
[10:22:02] <_methods> i had the same problem with an hdmi connection after install
[10:22:04] <bensbenz> or rather just a blank desktop
[10:22:19] <bensbenz> no its an old core2duo pc running VGA
[10:22:24] <_methods> ah
[10:22:42] <bensbenz> go the wireless card working automatically which was nice
[10:22:49] <_methods> well it wouldn't be linux if you didn't have to do some reading
[10:23:04] <_methods> it helps keep the dumb people away
[10:23:11] <bensbenz> lol
[10:23:27] <bensbenz> yeah but I am so used to the MS world, my day job is IT
[10:23:46] <thesaint444> hi guys, quick question - faster download source for linux cnc than via the website? thanks..
[10:23:55] <tiwake> that sounds horrible
[10:24:27] <bensbenz> its acutally not bad, I am not help desk or anything, that would be horrible
[10:24:48] <ssi> zeeshan: you use gui irc client? newb
[10:25:03] <zeeshan> haha
[10:25:11] <zeeshan> i like my tabs
[10:25:13] <ssi> http://www.duffelblog.com/2015/03/op-ed-i-sexually-identify-as-an-a-10-thunderbolt/
[10:25:17] <ssi> I have tabs
[10:25:21] <ssi> they're just in my mind
[10:25:26] <zeeshan> lol
[10:25:37] <tiwake> using an IRC bouncer too
[10:25:51] <tiwake> on my home server
[10:26:09] <ssi> I don't use a bouncer, I just have a permanent screen session on one of my servers
[10:26:18] <_methods> heh i just use a DO droplet
[10:26:23] <tiwake> enh
[10:26:30] <tiwake> I log in from a bunch of different places
[10:26:34] <_methods> if anyone hax0rs my box i just reinstall
[10:26:38] <tiwake> so an IRC bouncer is nice
[10:26:43] <_methods> spin up a new m
[10:26:44] <_methods> vm
[10:27:13] <ssi> zeeshan: https://www.youtube.com/watch?v=4rjQtYEV1Ts
[10:28:12] <tiwake> have ZNC installed on my headless debian minimal server
[10:28:31] <tiwake> http://tiwake.com/img_0063_small.jpg
[10:32:49] <bensbenz> Hey does anyone know if a c41 board works with linux CNC? The way it works now is spindle is cw if a pin is active low, ccw if its not, and spindle on if theres pwm going to it.
[10:33:26] <bensbenz> instead of a relay on two separate pins.
[10:33:52] <zeeshan> BEAST
[10:33:59] <zeeshan> whos this dude
[10:34:20] <zeeshan> that plane looks bad ass
[10:34:32] <zeeshan> its going to be SO nice to fly!!
[10:35:21] <zeeshan> is that a radial engine
[10:36:31] <tiwake> piston engines
[10:36:59] <tiwake> so last century
[10:38:24] <ssi> zeeshan: that's BJ
[10:38:25] <malcom2073> tiwake: What mobo is that?
[10:38:27] <ssi> and no, it's not a radial
[10:38:29] <ssi> it's a flat 4
[10:38:40] <zeeshan> well if his only complaint is
[10:38:42] <zeeshan> no foot pedal
[10:38:45] <zeeshan> er foot rest
[10:38:49] <zeeshan> it must be bad ass :-)
[10:39:01] <bensbenz> you like badass planes, this guy is my customer: http://chicago.cbslocal.com/2012/12/07/world-war-ii-fighter-raised-from-lake-michigan/
[10:39:07] <zeeshan> tell him foot rest only adds weight
[10:39:09] <tiwake> malcom2073: its a supermicro board with an intel D510... I don't remember the model off the top
[10:39:13] <ssi> zeeshan: he built the fuselage
[10:39:21] <zeeshan> ah
[10:39:24] <malcom2073> ah cool, good stuff
[10:39:36] <_methods> heh i have that same mobo i use for my pfsense router
[10:39:45] <_methods> good little board
[10:39:46] <bensbenz> he has a hanger full of them like this: http://www.warbirddepot.com/aircraft_fighters_p51-greenhill-2.asp
[10:39:57] <_methods> oh noes it's PetefromTn_
[10:39:58] <tiwake> I'm looking to upgrade it with something more capable
[10:40:10] <PetefromTn_> run fer yer lives!
[10:40:14] <zeeshan> PetefromTn_!~IceChat9@
[10:40:15] <zeeshan> !
[10:40:18] <tiwake> like the yet to be released AMD A1100
[10:41:31] <tiwake> partly cause I want 10G networking in my house :3
[10:41:50] <tiwake> and boot all my desktop computers over the network
[10:41:55] <_methods> oh new star wars trailer
[10:42:00] <zeeshan> looks good
[10:42:06] <zeeshan> chewyyyyyyyyy
[10:42:14] <tiwake> _methods: link?
[10:42:21] <_methods> https://www.youtube.com/watch?v=ngElkyQ6Rhs
[10:43:11] <PetefromTn_> It's gonna be AMAZING!!
[10:43:20] <PetefromTn_> I can't wait..
[10:43:26] <_methods> han solo
[10:45:14] <zeeshan> this teachings goes everything against my natural instinct
[10:45:29] <zeeshan> its better to take a full depth of cut
[10:45:52] <zeeshan> vs multiple axial depth of cuts + large radial depth of cut
[10:45:54] <zeeshan> ??!?!??
[10:45:59] <zeeshan> (for tool life)
[10:47:59] <zeeshan> i dont think that came out right. one axial depth of cut(.25" ie) + 4 adial cuts (.25" each to get a total of 1") vs 2 axial depth of cuts (.125 each to get .25" total) + 2 radial cuts (.5" each to get a total of 1")
[10:48:29] <PetefromTn_> Damn almost burnt my damn Ham and cheese sammich!!
[10:49:04] <PetefromTn_> coulda been a disaster..
[10:52:01] <ssi> zeeshan: sry, boss'd
[10:52:21] <ssi> zeeshan: he was bitching because there's lexan in the floor over the center cross tube where you'd normally put your feet to get in and out
[10:52:34] <ssi> I just step on the front seat tube, then hold the cabanes and shoot my feet out in front and slide down the back
[10:52:37] <ssi> it's not too bad
[10:54:23] <zeeshan> i love how the plane looks :-)
[10:55:03] <ssi> it looks amazing :D
[10:55:06] <ssi> I'm soooo thrilled
[11:03:40] <_methods> http://www.frys.com/product/8119235?site=72premail041715
[11:03:44] <_methods> there's a $50 off coupon
[11:03:48] <_methods> making that thing $199
[11:12:09] <archivist> zeeshan, depends... see insert data for the material, sandvik also quote life in hours of contact
[11:21:31] <bensbenz> anyone know if a standard fanuc turning post works with linuxcnc?
[11:22:27] <archivist> bensbenz, probably a good starting point
[11:23:00] <bensbenz> Thanks, anyone use HSMWorks?
[11:30:12] <ssi> _methods: I ended up breaking down and buying one of the pfsense hardware routers
[11:30:17] <ssi> and it's really really nice, but it was too much money :)
[11:37:12] <_methods> yeah i just use an old computer or whatever
[11:39:07] <bensbenz> I have 5 vms running pfsense at the house on an old dell server with 3 extra nics. I had a comcast outage and they guy came out the house and was like wtf is this... haha
[11:39:10] <ssi> I just bought a parachute :P
[11:39:41] <ssi> _methods: I used to just use an old computer, and I had it running for like six years, and then the power went out and it wouldn't come back up cause the hdd had died god knows how long ago :P
[11:39:56] <_methods> hahah
[11:39:59] <_methods> yeah that happens
[11:40:06] <_methods> i had one with 3 years uptime
[11:44:00] <_methods> what kind of chute did you get?
[11:44:05] <ssi> a softie
[11:44:10] <ssi> emergency chute, backpack style
[11:44:24] <ssi> http://www.barnstormers.com/ad_detail.php?ID=999413
[11:44:45] <_methods> $900 isn't bad
[11:44:51] <ssi> I paid $800 shipped
[11:45:48] <_methods> even better
[11:46:25] <ssi> that C9 canopy is ideal for my fat ass
[11:47:00] <_methods> just make sure your leg straps are tight
[11:47:11] <ssi> reading some forum posts about the canopy, and tests on it showed it was good to 450lb at 180kt, and 370lb at 300kt
[11:47:25] <ssi> yeah I've never jumped
[11:47:27] <ssi> I need to go do that
[11:47:33] <ssi> have a buddy that's an instructor
[11:47:50] <_methods> you don't want to get anything trapped between your strap and your leg when you pop your canopy lol
[11:47:54] <_methods> it's painful
[11:48:06] <ssi> you mean like your balls? :'(
[11:48:11] <_methods> yes those
[11:48:12] <ssi> hahaha
[11:48:21] <_methods> you get to vomit all the way down lol
[11:48:37] <ssi> dude if I ever have to use this thing I may be vomiting all the way down anyway
[11:48:48] <_methods> hahah
[11:49:56] <_methods> yeah you might want to go jump once or twice
[11:50:02] <_methods> it's fun
[11:50:11] <_methods> you probably get free rides too lol
[11:50:47] <ssi> heh probably not
[11:50:54] <ssi> they have a twatter they jump from, and I'm sure nobody rides free :)
[11:51:39] <_methods> yeah
[11:51:50] <_methods> i always wanted to do a balloon jump
[11:51:55] <_methods> i heard they are a blast
[11:52:07] <ssi> haha
[11:52:19] <_methods> like base jumping
[11:52:25] <_methods> no plane or chopper noise
[11:52:53] <ssi> yeah that would be cool
[11:53:02] <ssi> similarly, one day I want to go get my glider rating
[11:54:01] <_methods> i need to get my pilots license
[11:54:38] <ssi> I'll sell you the plane to do it in!
[11:54:42] <_methods> hahah
[11:54:51] <_methods> i think i'll just borrow one
[11:54:57] <ssi> nooooooo
[11:55:05] <_methods> wife said i can't go skydivin anymore
[11:55:09] <_methods> but i am allowed to fly
[11:55:12] <ssi> haha
[11:55:18] <ssi> then you need a cherokee!
[11:55:25] <ssi> it's the best first plane
[11:55:33] <ssi> and mine's faster than most
[11:55:52] <_methods> i gotta get my license first lol
[11:55:56] <ssi> and it can be yours for less than the price of a new camry!
[11:56:08] <ssi> it's WAY cheaper to buy a plane and get your license in it
[11:56:11] <ssi> I wish I'd done it that way
[11:56:16] <ssi> I bought the cherokee two weeks after I got my ticket
[11:56:18] <_methods> good tip
[11:56:24] <ssi> it cost me $10k to get my license
[11:56:31] <ssi> I could have paid off a huge chunk of the plane instead
[11:56:31] <_methods> i'll be hitting you up for more tips like that when i do it
[11:56:39] <_methods> i have some other stuff i have to do first
[11:57:02] <ssi> my plane has an autogas STC too... with fuel as cheap as it is, it'll cost something like $18-22/hr in fuel to run
[11:57:06] <ssi> plus $35-40 for an instructor
[11:57:14] <ssi> vs $140/hr for a plane rental and $35-40 for an instructor
[11:57:22] <ssi> it'll probably take 60+ hours
[11:57:23] <ssi> do that math
[11:57:52] <_methods> wow
[11:59:39] <ssi> http://superiorflight.com/aircraft/
[11:59:47] <ssi> there's the rates on the school planes at the airport by my house
[12:00:18] <ssi> also don't learn in a cessna
[12:00:19] <ssi> they blow
[12:00:58] <_methods> k
[12:01:08] <_methods> i got machines to build first though lol
[12:01:19] <ssi> haha yeah
[12:01:20] <ssi> me too :P
[12:01:56] <_methods> haha
[12:04:58] <Thomaxo_> _methods: you could go kiteboarding
[12:07:03] <ssi> _methods: what about powered paragliding?
[12:07:38] <_methods> yeah
[12:07:43] <zeeshan> is there a built in g-code
[12:07:48] <zeeshan> for helical interpolation
[12:07:52] <zeeshan> for circle milling holes?
[12:07:57] <ssi> yeah
[12:07:59] <_methods> jt made a nice py script
[12:08:11] <_methods> works great for pockets
[12:08:23] <zeeshan> i keep having to use cam to do it and it seems silly
[12:08:37] <_methods> you have google right lol
[12:08:40] <thesaint444> hi guys, anyone answer an install question?
[12:08:49] <_methods> google linuxcnc gcode generators
[12:08:53] <ssi> zeeshan: G2/G3 does helical arcts
[12:08:55] <ssi> arcs
[12:09:07] <archivist> thesaint444, only if you ask :)
[12:09:33] <zeeshan> ill use cam for now, will try to study scripts when ihas time
[12:09:42] <thesaint444> loading from live cd (usb stick) onto ssd drive, hangs after about 10% whilst copying files...
[12:09:52] <zeeshan> i literally modelled a part with a hole in it
[12:09:53] <zeeshan> lol
[12:09:59] <archivist> zeeshan, time you tried to script gcode!
[12:10:08] <zeeshan> ive only done basic stuff by hand
[12:10:20] <XXCoder> thesaint444: you sure your device has enough space to store files?
[12:10:28] <thesaint444> yes.. plenty.
[12:10:36] <thesaint444> 120gb..
[12:10:39] <XXCoder> yeah seemed unlikely but who knows.
[12:10:53] <thesaint444> checksums all good..
[12:11:41] <archivist> you could try a real hard disk
[12:12:07] <XXCoder> ssd is a real hard drive
[12:12:13] <thesaint444> could do.. lol. but it will work better with an ssd and i just bought it for this purpose..
[12:14:28] <thesaint444> something to do with the partition setup options/formating but i was hoping default would be fine..
[12:14:28] <XXCoder> oh yeah there apparently was breakthough on ssd tech
[12:14:37] <XXCoder> 10 tb ones will be possible soon
[12:15:08] <XXCoder> wonder will start beating even moores law again soon lol
[12:15:16] <SpeedEvil> No.
[12:15:32] <SpeedEvil> XXCoder: the problem is that 'Z' is a temporary short-term solution.
[12:15:41] <XXCoder> it is yeah
[12:15:54] <SpeedEvil> You can get a short-term benefit by going from 1-many stacked bits.
[12:16:04] <SpeedEvil> But - you can get much more dense than present on XY.
[12:16:07] <thesaint444> no suggestions?
[12:16:16] <XXCoder> I remember one book where storage was done by shaping space. infinite storage :P
[12:16:57] <SpeedEvil> In principle, for memory at least, there is no great reason why you can't have most of it turned off, and a _LOT_ of layers. But that does rely on each layer being very cheap.
[12:17:02] <archivist> thesaint444, we cannot see your "hang" have you googled the error with SSD in the search term
[12:17:02] <SpeedEvil> This desn't work for CPUs thugh
[12:17:23] <XXCoder> true
[12:17:41] <XXCoder> SpeedEvil: there was also new invention related to ssd, self-annealing
[12:17:44] <thesaint444> archivist - there is no error message - its a hang...
[12:17:54] <XXCoder> *sectors. it makes ssd basically immortal.
[12:19:24] <Thomaxo_> are there any tables for CNC-able materials?
[12:19:37] <SpeedEvil> Thomaxo_: ?
[12:19:43] <SpeedEvil> Thomaxo_: Anything is CNCable
[12:19:51] <SpeedEvil> you can CNC pasta or plutonium.
[12:20:09] <SpeedEvil> Anthracite or abalone
[12:20:34] <archivist> thesaint444, google something like "NAMEOFOS system hangs during installation on SSD"
[12:20:50] <Thomaxo_> heh, well, more talking about what kind of milling cutters at what rotation speed, etc
[12:21:07] <thesaint444> archivist - ok... thanks.
[12:21:10] <Thomaxo_> soft plastic would probably melt etc
[12:21:35] <archivist> that sort of info is for manual as well as cnc
[12:21:59] <Thomaxo_> that is true
[12:22:02] <archivist> tooling companies often have info to match the tooling
[12:22:06] <bensbenz> maybe load ubuntu 12.04 then follow wiki guide to install the rest
[12:22:28] <archivist> dunno if he is loading ubuntu or debian
[12:22:29] <thesaint444> Thomaxo - you need to do some reading about engineering. get a basic engineering workshop book to start with - it will give you and idea!
[12:22:54] <Thomaxo_> I will!
[12:22:58] <bensbenz> thesaint444 - I had issues with the livecd hybrid thing too, im going the ubuntu route, working so far.
[12:22:59] <Thomaxo_> thanks :)
[12:22:59] <thesaint444> bensbenz - yes, that will be my next step if i cant get this going..
[12:23:00] <archivist> practice on a macual machine to get the feel too
[12:23:03] <archivist> manual
[12:24:02] <thesaint444> Thomaxo - get a manual mill if possible and lathe - learn with them then go to cnc..
[12:24:19] <thesaint444> bensbenz - that is what i needed to hear - thanks...
[12:24:38] <archivist> night classes at the local college or hacker space
[12:24:40] <thesaint444> right, off to fiddle with linux installs, bye and thanks!
[12:24:59] <Thomaxo_> hmm, manual cnc seems like alot of work :)
[12:25:07] <Thomaxo_> manual mill*
[12:27:20] <Thomaxo_> i think i could probably manage with an engineering book, i have a good background in phsyics and maths
[12:27:40] <archivist> some machining is feel
[12:29:43] <bensbenz> Thomaxo - Youtube: mrpete222, oxtoolsco, keith fenner
[12:29:46] <archivist> one listens to the noise of the cut(or feel the machine vibration) as much as look at the cut finish
[12:30:25] <bensbenz> for manual stuff
[12:31:00] <Thomaxo_> i'll check those channels out
[12:31:04] <archivist> if you can feel then http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_07_Lorch_lathe/IMG_1822.JPG hand turning will be easy
[12:31:37] <bensbenz> thomaxo for CNC stuff guys like nyccnc, and John Grimso
[12:31:59] <bensbenz> *grimsmo
[12:32:11] <ssi> archivist: is that a 3C collet machine?
[12:32:11] <Thomaxo_> and those as well :)
[12:32:32] <archivist> ssi, no its a Lorch own size I think
[12:32:35] <ssi> ah
[12:32:39] <CaptHindsight> 75F sun, low humidity and no bugs yet, we get like 10 days a year like this here
[12:32:41] <ssi> it's cute
[12:33:01] <Thomaxo_> there probably doesn't exist a set of formulas to tell me how fast i could go trough a material or at what rotation speed?
[12:33:02] <archivist> ssi about 70mm centre height
[12:33:41] <archivist> Thomaxo_, there are ranges depending on various factors
[12:34:25] <archivist> cutting tool, material and importantly, machine rigidity
[12:34:44] <archivist> loads of people get the last one wrong
[12:35:44] <mutley> wow, two days of intense cnc investigations and machining, end result good
[12:35:48] <ssi> yeah pretty much by the time you have the rigidity required by the tables, you have the experience to not need them anymore :P
[12:35:48] <archivist> there is also work piece flexing and cutter flexing that affect the conditions
[12:36:21] <mutley> Thomaxo_: there are many feeds and speeds calculators covering all known materials or equivalents
[12:37:05] <archivist> and all probably assume a real machine not a cheap gantry router
[12:37:31] <mutley> anyways, after sorting that motion issue the crept in after an update, ive actually managed to further resolve (or at least identify root cause) or circles not being circles
[12:38:12] <FinboySlick> mutley: I'm curious. I had non-circle circles too.
[12:38:42] * archivist guesses drivers powering down and losing steps
[12:39:59] <mutley> archivist: yea your probably right, although they are starting points, and if you are deserving of having a cheap gantry version you should at least have the comon sense to compensate or at least stiffen up the gantry and not try to cut tungsten titanium kryptonite alloys ;p
[12:40:24] <Thomaxo_> hmm ok, i have lots of research to then :)
[12:41:05] <mutley> Thomaxo_: its a learning curve, as steep as you want it to be, and as expensive (or cheap) as the effort and investment you put in, same goes with anything really
[12:41:28] <mutley> so, circles aint crcles, but they are now (almost)
[12:41:31] <archivist> mutley, yup machine stiffness helps people make fewer mistakes, gantry being a more flexible design
[12:42:32] <Thomaxo_> well learning is fun!
[12:42:33] <archivist> add webs to stiffen so the cutting force is not bending the structure
[12:42:37] <mutley> checked and triple quad checked everything, fro mechanical possibilities to tool deflection to gantry flex through to all settings in the unnamed cnc controller i inherited
[12:42:50] <mutley> ultimately i had a combination of a couple of problems
[12:42:58] <mutley> mechanically everything was sound, ganty good etc
[12:43:22] <mutley> i had tool delfection of the aforementioned 1mm diameter 13mm reach bit
[12:43:29] <archivist> yes but what effort to flex how much, measure
[12:43:44] <mutley> but i had compensated for that by slowing feeds rightdown, snails racing past the bit
[12:44:00] <mutley> but still had this very consistent 0.2mm out of round
[12:44:32] <mutley> noticed that step/dir delay was at 30us
[12:44:41] <mutley> my driver manual mentioned 5us
[12:45:10] <mutley> so i dropped it from 30 to 10 to be safe, and now im 0.08 out of round
[12:45:47] <mutley> rechecked by putting it back to 30, cut a new piece, back to 0.2mm out of round, droped back to 10us and low and behold, 0.08 again
[12:45:54] <archivist> I recommend disabling driver power down function if you can
[12:46:20] <mutley> a freaking year this has been plaguing me
[12:46:37] <mutley> think ive ernt the right to a rare glass of red this evening
[12:47:24] <mutley> archivist: ill look into that
[12:48:00] <mutley> i might go for the driver manf recommended setting of 5us and see what that does, but no more for today, neighbours are home and its evening
[12:48:27] <mutley> however, tomorrow night, cnc party night, neighbours away so all i can disturb are the sheep in the field
[12:50:40] <zeeshan> HEHE
[12:50:44] <zeeshan> im eating aluminum !
[12:50:55] <lair82_> Trying not to duplicate asking questions, but, I started moving the slides around today on my latest build, and was wondering if there may be a bug with the calibration utility. I am running Debian with RT Preempt, using gscreen. It says my INI file is not compatible with emccalib.tcl.
[12:51:48] <archivist> not sure anyone keeps the tcl stuff up to date
[12:52:50] <lair82_> It said that I have "No tune-able items in 10VC.INI"
[12:53:31] <skunkworks> it also tells you that you need [axis_0] P=1 for example
[12:53:40] <skunkworks> do you have those in your ini?
[12:53:45] <lair82_> When it is laid out carbon copy to the integrator manual, and the exact same as the last three machines I setup using Linuxcnc.
[12:54:04] <archivist> I see recent commits keeping it up to date and fixing bugs
[12:54:17] <lair82_> skunkworks that is correct
[12:54:39] <skunkworks> it might also need the correct setp's in the hal file...
[12:54:53] <skunkworks> do you have your hal and ini file somewhere?
[12:55:31] <lair82_> Yep, let me post them on pastebin, be back in a few,
[12:57:05] <mutley> anyways, just want to say a huge thanks to thise that threw comment and suggestion my way that put me on the right track to resolving my issues (well cnc related ones anyway)
[13:01:58] <lair82_> Here is my hal file, http://pastebin.com/CRGSKagG and here is my INI file, http://pastebin.com/uQXcD8Mv
[13:09:40] <lair82_> skunkworks, When I was writing my hal file, I copied the data section by section from one of my turning centers, which works perfectly.
[13:10:06] <mutley> ah well, let the clean up begin
[13:13:24] <skunkworks> not seeing anything out of the ordinary.. Could you bring up axi using the same hal/ini file and see if it works?
[13:13:46] <lair82_> Will do, report back in a bit.
[13:16:16] <dgarr> lair82_: your hal file is very confused: you use loadrt pid num_chan=3 which creates pins like pid.0.* but later you refer to pins named pid.x.*
[13:28:01] <lair82_> I posted the wrong one, here is the correct HAL file, http://pastebin.com/Bn0UrZtM
[13:32:36] <lair82_> dgarr I thought I threw that first one out, apparently not.
[13:33:50] <skunkworks> you wouldn't happen to be creating/editing the files on a windows machine?
[13:38:24] <lair82_> No, I did all my work on my test machine, which is setup for debian.
[13:43:02] <lair82_> Unless gedit was saving as windows format, and I didn't realize it.
[13:46:51] <dgarr> lair82_: in a terminal please enter: linuxcnc_var all and post result
[13:47:49] <dgarr> (if rip, make sure to source scripts/rip-environment first)
[13:51:39] <lair82> dgarr, here is what I got, greenmill@greenmill:~/linuxcnc-dev$ linuxcnc_var all LINUXCNCVERSION=2.8.0~pre1 REALTIME=/home/greenmill/linuxcnc-dev/scripts/realtime RTS=uspace HALLIB_DIR=/home/greenmill/linuxcnc-dev/lib/hallib greenmill@greenmill:~/linuxcnc-dev$
[13:53:17] <lair82> I tried to find the emccalib.tcl file, find: `emccalib.tcl': No such file or directory greenmill@greenmill:~$
[13:53:37] <lair82> Just to see if maybe I could hash out what the problem may be
[14:15:00] <lair82> I am beginning to think my machine is cursed,
[14:15:50] <dgarr> suggest you make a zip file for the non-working configuration directory and post it somewhere
[14:19:00] <Cromaglious_> lair82, open a xterm window: find ~ -name emccqlib.tcl
[14:19:10] <Cromaglious_> lair82, open a xterm window: find ~ -name emccalib.tcl
[14:19:46] <dgarr> emcalib.tcl is /home/greenmill/linuxcnc-dev/tcl/bin (save a copy if you experiment with it)
[14:25:04] <dgarr> lair82: remove the leading whitepace (spaces,tabs) in front of the setp lines like setp pid.*.* [AXIS_*]* and test please
[14:25:53] <skunkworks> ooh...
[14:27:14] <lair82> Amazing what will stop things from working properly. It works now.
[14:28:11] <lair82> Why would that make a difference now, all three other machines files are setup this way, and I have never had a problem.
[14:29:11] <Cromaglious_> different parser used on that file?
[14:32:43] <skunkworks> tabs vs spaces?
[14:35:20] <Cromaglious_> that or WS vs no whitespace
[14:36:27] <Cromaglious_> or the insideous parser called COBOL, where everything has to be in the required column
[14:37:48] <dgarr> the problem with leading spaces was probably introduced by a commit that fixed a diifferent problem, namely http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=commitdiff;h=0ab1301a6185ab072d1d0415cc506c7789a368d8
[14:38:59] <dgarr> git tag --contains 0ab1301a6 indicates all it is in all branches after v2.6.4
[14:41:15] <Cromaglious_> so $tmpstring needs a trim on the line before it.
[14:44:19] <Cromaglious_> dunno tcl, $WhiteSpace = " "+ chr$(9): while instr($WhiteSpace, left$($tmpstring,1)) : $tmpstring=mid$($tmpstring,2): wend
[14:47:25] <dgarr> patch http://www.panix.com/~dgarrett/stuff/0001-emccalib.tcl-allow-whitespace-on-detected-setp-lines.patch
[14:52:59] <lair82> Thanks for the help guys, now I'm moving along again. Have a good weekend
[14:53:24] <lair82> Time or me to hit it for the weekend.
[14:53:41] <thesaint444> anyone here had problems with the live install and ssd drives?
[14:54:10] <_methods> i had a problem with mine on hdmi
[14:54:13] <_methods> not ssd though
[14:54:48] <thesaint444> think it might be something with old board and new drive..
[14:54:53] <_methods> had to add a flag to the boot line to get it to load with hdmi
[14:55:17] <_methods> that was getting the installer to load up
[14:55:30] <thesaint444> any itx form factor recommendations?
[14:55:41] <Cromaglious_> board or case?
[14:55:49] <thesaint444> board..
[14:55:54] <Cromaglious_> I really like the minibox cases
[14:56:00] <Cromaglious_> mini-box.com
[14:56:11] <Cromaglious_> I have 2
[14:56:11] <thesaint444> and a modern main board?
[14:56:28] <_methods> i think i'm using a gigabyte with an i3 or soemthing
[14:56:34] <_methods> let me check my newegg order history
[14:56:43] <thesaint444> thanks!
[14:56:45] <_methods> it's been really awesome compared to mother one
[14:56:54] <_methods> s/mother/my other
[14:56:55] <_methods> lol
[14:57:03] <thesaint444> lol..
[14:57:10] <Cromaglious_> mine are older atom boards, I really need a newer ITX board
[14:57:11] <_methods> my other mill is using a pc with a dual core amd
[14:57:15] <_methods> really showing its age now
[14:57:18] <thesaint444> was trying to to use an older atom..
[14:58:15] <thesaint444> it is not liking my new ssd..
[14:58:15] <Cromaglious_> I just spent all my spurge money on getting arduino mega, uno, and nano boards
[14:58:41] <Cromaglious_> splurge
[14:58:51] <Rab> Cromaglious_, how is your chinese engraving spindle?
[14:59:07] <Cromaglious_> my 400w is working good
[14:59:45] <Cromaglious_> the pwm board I got works pretty good. haven't wired in the over current yet though
[15:00:12] <Rab> What types of tools/materials have you tried?
[15:00:58] <Cromaglious_> wood: oak, pine, mdf; metal copper, AL
[15:01:45] <Cromaglious_> er11 using 3.175mm 1/8" bits mostly
[15:03:01] <Cromaglious_> tried a 3/16" shank, 0.025" end mill. It cut about 1 inch before I broke it at 1ipm
[15:03:24] <Cromaglious_> in 0.040 AL
[15:03:57] <Cromaglious_> next time I use one it'll be .5ipm and lots of wd-40
[15:04:30] <zeeshan> what rpm do you spin at?
[15:04:32] <_methods> ah i'm running it on a ga-z68ma microatx
[15:04:42] <_methods> with an i3-2100
[15:04:58] <Cromaglious_> I'm running mainly at 8K to 12K
[15:05:01] <_methods> i put a seasonic fanless power supply in it too
[15:05:17] <_methods> i need to get rid of the fan on the cpu too
[15:05:32] <zeeshan> http://imgur.com/a/11S9H
[15:05:37] <zeeshan> its starting to come otgether
[15:05:41] <_methods> it used to be my htpc
[15:05:53] <_methods> but roku's and chromecasts killed my need for htpc
[15:06:38] <zeeshan> whats an easy to use/free video editting software
[15:06:43] <zeeshan> to like join videos
[15:06:49] <zeeshan> do some fading
[15:06:55] <zeeshan> add some text
[15:07:23] <Cromaglious_> zeeshan, what's that gonna be?
[15:08:11] <zeeshan> a sculpture that an artist is working on
[15:08:25] <zeeshan> its one of those interactive sculptures for the city
[15:08:35] <zeeshan> has to do with water treatment
[15:08:40] <_methods> yeah sure
[15:08:51] <Cromaglious_> thing about the 3040 is it flexes really bad.. z deflection it 0.015 at 2#'s
[15:09:03] <zeeshan> lol
[15:09:05] <zeeshan> thats a lot
[15:09:17] <zeeshan> do the engraves visually look okay though?
[15:09:30] <Cromaglious_> if I go slow enough
[15:10:01] <zeeshan> .5 ipm at 10000 rpm seems like
[15:10:02] <Cromaglious_> my problem is holding the 0.040 AL flat enough
[15:10:04] <zeeshan> youre not really cutting?
[15:10:35] <zeeshan> how many flutes on the engraving bit?
[15:10:41] <Cromaglious_> 3
[15:11:17] <Cromaglious_> 2 on the 0.025 and 2 on the 0.008
[15:11:42] <Cromaglious_> 3 on the 60degree and 1 on the 30degree
[15:11:47] <Rab> Cromaglious_, what was your depth of cut for .125
[15:11:50] <Rab> in Al?
[15:12:12] <zeeshan> chip load = approx uncut chip thickness = feed / (n * teeth) = 0.5/(10000*3)
[15:12:36] <zeeshan> 0.0000166
[15:12:38] <zeeshan> wow
[15:12:48] <zeeshan> youre just rubbing
[15:13:00] <Cromaglious_> in the 0.5 stock I'm using 0.100 with a 0.002 step over at 8Krpm
[15:13:56] <Cromaglious_> at 10ipm
[15:13:56] <zeeshan> the cutting edge is anywhere between 0.0003" to 0.002"
[15:14:17] <zeeshan> if youre feeding less than that value, youre just plastically deforming the material, not shearing it :D
[15:14:37] <zeeshan> do you have a pic of the engraving?
[15:14:51] <Cromaglious_> not a close up
[15:15:03] <Rab> Cromaglious_, cool, sounds like that little spindle isn't a bad deal for the money.
[15:15:26] <Cromaglious_> spindle is more capable than the mechanism
[15:15:42] <_methods> yeah i need to get one of those spindles
[15:15:48] <_methods> how much was that 400w?
[15:15:55] <Cromaglious_> checking
[15:16:08] <_methods> did it come with vfd too?
[15:17:09] <Cromaglious_> http://www.ebay.com/itm/281526915107?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[15:17:12] <Cromaglious_> it's DC
[15:17:33] <Cromaglious_> here's the pwm controller
[15:17:34] <Cromaglious_> http://www.ebay.com/itm/261599588503?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[15:17:41] <_methods> ahhh i halready have one of those
[15:17:49] <_methods> i thought you had one of the water cooled ones with vfd
[15:17:50] <zeeshan> 2inch body diameter
[15:17:50] <zeeshan> hmm
[15:17:52] <Cromaglious_> $56 and $19
[15:17:56] <zeeshan> i wonder if i can make a cat40 holder for it
[15:18:02] <Cromaglious_> 52mm
[15:18:11] <_methods> yeah i use the motor on my pcb mill
[15:18:16] <_methods> works good
[15:18:45] <Cromaglious_> 8mm shaft er11 collet runout is acceptable
[15:18:59] <zeeshan> that thing is basically a dremel!
[15:19:00] <zeeshan> :D
[15:19:05] <_methods> yeah i can cut smd pcbs with it
[15:19:10] <_methods> works good
[15:19:11] <Cromaglious_> hell of alot quiter
[15:19:30] <Cromaglious_> quieter
[15:19:36] <_methods> yeah silent
[15:19:51] <_methods> compared to dremel
[15:21:36] <Cromaglious_> zeeshan, it's right around 8" overall length and fan sticks up about 1.75" off the end.
[15:21:48] <zeeshan> lol
[15:21:51] <zeeshan> thats not gonna work then
[15:21:57] <zeeshan> my z limit is 14.75"
[15:22:19] <zeeshan> when i get more time this winter
[15:22:24] <zeeshan> i might make a new vertical head for it
[15:22:35] <Cromaglious_> what's the actual cat40 face to table max distance?
[15:22:52] <zeeshan> about 20"
[15:22:58] <zeeshan> to 18
[15:23:26] <Cromaglious_> so you'd have 9" to 12"
[15:23:37] <zeeshan> yes but if you add the vise
[15:23:42] <zeeshan> now its like 5" more gone
[15:24:07] <Cromaglious_> then the bit, so you're down to like 3"
[15:24:13] <zeeshan> hehe
[15:24:18] <zeeshan> i think a vertical head makes sense
[15:24:46] <zeeshan> i could make a epicyclic gear setup for it
[15:24:58] <Cromaglious_> heh put a dove tail on the side of you head
[15:25:00] <zeeshan> basically a spindle speeder
[15:25:14] <Cromaglious_> or linear rails
[15:25:31] <Cromaglious_> make a Z for the spindle
[15:25:53] <zeeshan> i think ill do a planetary gears etup
[15:26:01] <zeeshan> because those things can do like 50:1 speed boost
[15:26:25] <zeeshan> was it 50 to 1
[15:26:27] <zeeshan> hmm
[15:26:35] <zeeshan> maybe it was 5:1
[15:26:54] <Cromaglious_> hmm fixed ring, drive the planets and spindle is the sun?
[15:27:18] <Cromaglious_> that would give you 15k
[15:28:41] <zeeshan> i havent looked at this type of gear transmission in a long time
[15:28:45] <zeeshan> ill have to revisit
[15:28:59] <zeeshan> i forgot how they worked :)
[15:29:31] <zeeshan> i _think_ if you spin the sun using the spindle power
[15:29:53] <zeeshan> (ring gear)
[15:30:06] <zeeshan> okay lemme use the terms i remember
[15:30:27] <zeeshan> the ring gear (outer most gear) if you spin this, then the gear at the very center spins faster
[15:30:38] <zeeshan> depending on the plant gears
[15:30:41] <zeeshan> *planet
[16:02:06] <Tom_itx> zeeshan, find some engraving bits?
[16:02:21] <zeeshan> no
[16:02:25] <zeeshan> he doesnt want it engraved anymore
[16:02:27] <zeeshan> we did the slots instead
[16:02:35] <zeeshan> look a lot better than having some random logo engraved
[16:02:38] <zeeshan> did you see?
[16:03:22] <zeeshan> be back later tonight :p
[16:03:29] <zeeshan> its relax time!
[16:09:52] <Cromaglious_> it's kinda nice having 3 mice on one computer... depending on where I sit, I have a mouse
[16:12:12] <Cromaglious_> ugh crappy example code, expects G20, but it doesn't have it in the file
[16:25:53] <Deejay__> gn8
[16:49:36] <Cromaglious_> hmm
[16:50:01] <Cromaglious_> RapR3D editor will not install
[19:09:17] <zeeshan--> hi
[19:09:26] <malcom2073> Hi
[19:09:30] <zeeshan--> has anyone heard of a seiberco servo drive
[19:09:41] <malcom2073> Not I
[19:10:28] <malcom2073> Did some work on this silly wooden model of a steam engine, couple of design flaws keeping it from actually runnin smoothl on compressed air. Gonna rebuild the main piston and valve piston, be a good practice on the lathe
[19:26:26] <zeeshan--> hi
[19:30:28] <malcom2073> Hi again
[19:34:37] <zeeshan--> what kind of lathe do you have
[19:35:34] <malcom2073> an old southbend 9C-36
[19:35:36] <malcom2073> 1930's era
[19:40:34] <malcom2073> zeeshan--: http://mikesshop.net/lathe/DSCN1943.JPG
[20:07:09] <zeeshan--> interesting lathe
[20:07:19] <malcom2073> It is interesting heh
[20:07:31] <malcom2073> Needs some work, but it does ok
[20:07:51] <malcom2073> I have a DRO I'ma attach to it, bring it into the modern world
[20:08:26] <zeeshan--> hehe
[20:08:44] <malcom2073> Mainly, because when playing around, a couple times I lost count of how many times I'd rotated the handle :)
[20:09:40] <malcom2073> It's gonna get taken apart and cleaned up/repainted here pretty soon
[20:09:48] <malcom2073> It's as I bought it atm, pretty nasty
[20:40:06] <Cromaglious_> yay! I have a lathe newer than someone else!
[20:41:04] <Cromaglious_> <- 1945ish Sheldon 10" leather belt overhead drive, QC gear box
[20:42:08] <Cromaglious_> http://itslinux.org/Lathe.jpg
[20:43:03] <Cromaglious_> but he has a qctp on his :(
[20:43:52] <Cromaglious_> I really need to get one, using hacksaw blade to shim bits up really sucks
[20:44:02] <Cromaglious_> s/blade/blades/
[20:45:22] <Cromaglious_> malcom2073, your qctp it's a piston or wedge?
[20:49:21] <skunkworks> I keep meaning to create a tracker
[20:51:12] <Cromaglious_> don't anyone bid on this http://www.ebay.com/itm/Quick-Change-Tool-Post-New-/291432912058
[20:51:21] <Cromaglious_> unless your going over $80
[20:51:51] <Cromaglious_> it's at 52 right now... my max bid is 80
[20:54:24] <Cromaglious_> BXA w/ 5 holders
[20:55:19] <Cromaglious_> I wish I could spend more
[20:55:36] <Cromaglious_> my wife is gonna kill me at $80 if I get it
[21:14:38] <malcom2073> Cromaglious_: wdge
[21:15:31] <malcom2073> wedge
[21:18:05] <malcom2073> erm, I think
[21:19:31] <malcom2073> Looking up the difference now :P
[21:19:33] <malcom2073> Looks like piston
[21:20:41] <malcom2073> Well... I'm unsure :/
[22:53:40] <Cromaglious_> wedge one side of the dove tail moves, on piston the dove tail is the same with apiston coming out in the center to push the holder out against the dove tails
[22:59:01] <Cromaglious_> some body just bid up the qctp up to $81 from $53 two dollars at a time
[22:59:46] <Cromaglious_> now to let them bid it up to $86
[23:05:23] <Cromaglious_> malcom2073, this is a wedge type http://www.ebay.com/itm/AXA-WEDGE-TOOL-POST-SET-CNC-HIGH-PRECISION-QUICK-CHANGE-LATHE-HOLDERS-100-SERIES-/111578743893?pt=LH_DefaultDomain_0&hash=item19fa9c8455
[23:07:34] <Cromaglious_> looks like yours is a wedge type 250-111
