[11:10:57] <PetefromTn> Afternoon folks...
[11:47:25] <Tom_itx> soggy day
[11:50:25] <archivist> hot day with all the doors open here :)
[11:52:36] <IchGuckLive> hi all B)
[11:59:40] <sliptonic> Trying to play with gscreen / gladevcp. The sim configs work fine but when I try to edit .ui file I get this error "The following required catalogs are unavailable: gladevcp" That's running glade from the command line in the rip directory after executing the script.
[12:18:03] <CaptHindsight> http://chicago.craigslist.org/wcl/tls/3916789945.html when welders were welders
[12:29:05] <cmorley1> sliptonic: You must run glade after settinng the linuxcnc environment. i assume you are using a run-in-place compiled version.
[12:30:07] <cmorley1> oops i should read the rest of your sentence .... :)
[12:31:55] <cmorley1> Oh what version of GLADE editor are you using? Are you using 12.04? if so you must use that GLADE editor that uses GTK2 not GTK3
[12:32:40] <sliptonic> cmorley1: I bet that's it. I took the default for my mint maya installation. I'm sure it's gtk3
[12:33:20] <cmorley1> Yep. You can get the GTK2 version from their repository.
[13:27:07] <ReadError> any cool addons that can estimate time to completion based on the gcode/feedrates?
[13:29:24] <cradek> file/about
[13:29:42] <cradek> er well, that's total time
[13:29:49] <cradek> use that and look at the scrollbar :-)
[14:59:23] <Aero-Tec3> need some advice
[14:59:42] <Aero-Tec3> I would like to drill a hole using a lathe
[15:00:42] <Aero-Tec3> 0.338 dia 2.5 inch deep
[15:01:39] <Aero-Tec3> any recommendations for Gcode to use and setting in the Gcode?
[15:17:51] <Aero-Tec3> kind of dead here
[15:18:21] <mk0> see what is the time in the usa )
[15:19:19] <Aero-Tec3> skunkworks, can you make any recommendations based on the above info?
[15:19:27] <Aero-Tec3> I am in Canada
[15:19:47] <mk0> oh yeaaaah ))
[15:19:56] <Aero-Tec3> 1 pm here in the west
[15:20:03] <Aero-Tec3> 4 in the east
[15:20:22] <Aero-Tec3> not bed time yet
[15:20:23] <Aero-Tec3> lol
[15:20:30] <mk0> i know
[15:20:41] <Aero-Tec3> where are you?
[15:20:45] <mk0> i meant usa time = canada )
[15:20:58] <mk0> i'm in bed time ))
[15:21:10] <mk0> 23.05
[15:21:41] <Aero-Tec3> looking for lathe guys
[15:22:33] <Aero-Tec3> need to drill holes in 316 ss as straight as possible
[15:23:03] <Aero-Tec3> also need to drill 12L14 steel same as the 316 ss
[15:37:36] <rob_h> not too much RPM as SS work hardnes as you know.. flood coolant.. pecking for chip cleanace , if you can start with stub then go jobber. a Tin coated drill in HSS will work fine
[15:38:01] <rob_h> you dont say if you need to hold a size or how many holes
[15:38:33] <rob_h> dont know what 12L14 is.. in UK here
[15:39:00] <rob_h> o En1A
[15:40:11] <Aero-Tec3> 12L14 is a leaded mild steel
[15:40:18] <rob_h> yea i looked it up,
[15:40:21] <Aero-Tec3> real nice to machine
[15:40:54] <Aero-Tec3> there are a few choices to choose from for drilling
[15:41:08] <Aero-Tec3> and not sure what Q does
[15:41:17] <rob_h> Q is peck depth
[15:41:28] <rob_h> ie, drills to Q value then does a peck/retract
[15:41:31] <Aero-Tec3> I need it to be as straight as possible
[15:41:51] <rob_h> center drill it, or use a self centering drill..
[15:42:07] <Aero-Tec3> it said something about delta
[15:42:23] <rob_h> when i need to get a good stright hole, i will always stub drill it.. then go in with longer to get down to depth
[15:42:34] <rob_h> https://www.youtube.com/watch?v=d4O_nOclcAs
[15:42:35] <t12> what does straight as possible mean exactly
[15:42:55] <rob_h> a vid i did other day drilling EN19T tho abit tougher than ur 1A
[15:43:14] <rob_h> t12, i guess not 90deg lol
[15:43:15] <Aero-Tec3> for muzzle break on a gun
[15:43:29] <Aero-Tec3> so as straight as possible
[15:43:38] <rob_h> what about hole finish?
[15:43:41] <Aero-Tec3> one hole down the center
[15:43:49] <t12> start the hole with tooling instead of a drill, measure it to tolerance, drill, ream?
[15:44:02] <Aero-Tec3> smooth would be nice but not a big deal
[15:44:31] <Aero-Tec3> ream not necessary
[15:44:56] <t12> are you making it from stock?
[15:45:04] <Aero-Tec3> yes
[15:45:19] <Aero-Tec3> I have 300 to make
[15:45:44] <Aero-Tec3> well closer to 330
[15:47:43] <Aero-Tec3> in mach I wrote a custom sub for drilling
[15:48:07] <Aero-Tec3> I would like to take smaller bites the deeper I go
[15:48:49] <Aero-Tec3> with pecking for chip braking
[15:54:14] <t12> heh
[15:54:16] <t12> gun drill!
[15:56:10] <t12> http://a_viktor.tripod.com/PeterThesisWriter.pdf
[15:56:11] <t12> dang
[16:09:39] <Aero-Tec3> tad extreme for a 2.5 inch hole, also not set up for it, but the thought had crossed my mind
[16:23:59] <DJ9DJ> gn8
[17:51:59] <Getty> and it cant be that easy, you guys are like telling me that i totally ignored this giant piece of solution world all the time, just cause i dont wanted to connect some wires?
[17:52:39] <Jymmm> JT-Shop: What do you think? http://sfbay.craigslist.org/sby/mcy/3923861555.html
[18:02:38] <Jymmm> JT-Shop: Another one... http://sfbay.craigslist.org/sby/mcy/3931914580.html
[18:23:30] <Getty> the webpage really needs a screenshot section with like just all relevant features, i know i am probably not the first saying it, when i first time really run it i will probably make some
[18:31:04] <Aero-Tec3> for the new guy it is very over whelming unless your doing just a basic setup
[18:31:39] <Getty> the problem is that you dont see what it covers really, i now understand it
[18:32:01] <Aero-Tec3> all of it?
[18:32:08] <Getty> "all of it"?
[18:32:11] <sliptonic> gscreen works in sim. It also launches my mill configuration and will home everything. But when I try to jog an axis, it throws an error like this: http://img1.imagebanana.com/img/x8v0bv1i/Selection_001.png
[18:32:17] <Aero-Tec3> it is very big and very involved
[18:32:30] <Getty> i know where it gives in and what comes out, that is enough to put it in the right context
[18:32:37] <Getty> which was the core point for now for me
[18:35:50] <Aero-Tec3> sim is easy
[18:36:02] <Aero-Tec3> wait till your running a machine
[18:36:13] <Aero-Tec3> getting it all working
[18:36:36] <Aero-Tec3> never seen the Gscreen before
[18:36:42] <Aero-Tec3> I run axis
[18:37:19] <Aero-Tec3> gscreen looks nice, will have to look into it more
[18:37:44] <Getty> i will see all that when i come to the point, right now i just wanted to see what is covered
[18:37:53] <Getty> relevant for me is now that i have a very big freedom on the device choice
[18:38:29] <Getty> i just need to count the I/O i need and see if there is enough on the beagleboard, and i think that is clearly given.... so its all straight forward, of course then it will need lots of time till the stuff does what i want ;)
[18:46:52] <Aero-Tec3> why use beagleboard?
[18:47:06] <Aero-Tec3> it is new to linux cnc and could be buggy
[18:47:47] <Aero-Tec3> there are much better choices out there for your needs
[18:48:16] <Getty> beagleboard is already in use on other parts of projects around this, it would be in the company flow
[18:48:27] <Getty> what you suggest, i am flexible, as I/O?
[18:48:46] <Getty> beagleboard is just many I/O for low money ;)
[18:52:39] <Aero-Tec3> you can use it to communicate with other systems or machines in the shop if need be, but for a hard hitting good solid commercial machine you would be much better off with Mesa Electronics
[18:53:30] <Aero-Tec3> tried and true, guys are doing some extraordinary things using Mesa Electronics parts
[18:53:32] <Getty> its just one machine, and that answers the cluster question ;) hehe, no just beagleboard for I/O would be totally fine
[18:53:59] <Aero-Tec3> as much I/O as you can possibly want, fast as well
[18:54:00] <Getty> i would then use an additional pointless mini-itx i still have spare for the touchscreen and the linuxcnc interface itself (which can of course be started to any desktop anyway)
[18:56:01] <Getty> cant find the mesa stuff anywhere for buy beside mesa webpage itself so far
[18:56:17] <Getty> must checkup to compare
[18:57:59] <andypugh> Getty: A Mini-ITX board is the ideal thing to use. You can start off using the parallel port (and that may be all you ever need) but you will have a much better idea what you want to do and how to do it after building a simple practice system.
[18:58:33] <andypugh> As far as I know Mesa stuff is only available from Mesa and a couple of distributors in Europe.
[18:58:40] <Getty> parallel port.... you say it like it still is something that exist ;) haha but yeah some board flowing around with that probably
[18:59:24] <andypugh> You can still buy boards with parallel ports, though they often only exist as a header on the motherboard rather than the back panel.
[18:59:33] <Getty> yeah i know
[19:00:54] <Getty> which leads back to the question why not just use the beagleboard, i mean i bet even if its new to linuxcnc, that problems on that path will be fixed
[19:01:07] <Getty> and if not.. then i just use something else ;) its not like the world explodes on a switch there
[19:01:35] <Getty> but i think it might be a worthy target to try it on beagleboard
[19:09:20] <andypugh> There isn't a huge amount of supported hardware for the Beagleboard yet, and you can't run a current released version of LinuxCNC, you need to use a development version and jump through hoops. But other than that, feel free.
[19:10:00] <Getty> yeah till i reach this point some more days are in
[19:14:06] <Aero-Tec3> right now I am running just a plain old parallel port for both lathe and mill
[19:14:35] <Aero-Tec3> separate computers for each
[19:14:47] <Aero-Tec3> hard to get much cheaper
[19:19:33] <Getty> yeah ok, the parallel PCI card is 13,99 EUR the beagle board is 25 EUR, ok yeah ;)
[19:22:09] <andypugh> Beagle is actually €35
[19:23:13] <andypugh> Still probably the cheapest part of any CNC system.
[19:23:17] <Getty> oh yeah, mixed it up with the tweeny
[19:23:34] <andypugh> Anyway, work tomorrow
[19:56:09] <Aero-Tec3> is there a Gcode in linuxcnc for drilling that makes pecks smaller the deeper it goes?
[20:06:31] <PetefromTn> Hey Folks!!
[20:14:25] <Aero-Tec3> hey
[20:15:00] <PetefromTn> Damn this place seems dead lately...
[20:17:00] <Aero-Tec3> sunday
[20:17:10] <Aero-Tec3> late for most guys
[20:17:19] <KimK> Hi PetefromTn, how's it going?
[20:17:40] <Aero-Tec3> just us north America guys here now
[20:17:57] <Aero-Tec3> yo kim
[20:18:06] <KimK> Hi Aero-Tec3
[20:18:07] <Aero-Tec3> are you a lathe guy?
[20:18:31] <Aero-Tec3> I know your a reprap guy
[20:18:43] <PetefromTn> Hey KimK
[20:18:49] <KimK> On occasion, but not much turning here
[20:19:01] <PetefromTn> I got a lathe but it is not CNC.
[20:19:03] <Aero-Tec3> will be talking to you more about that as I want to make a emc controlled reprap
[20:19:28] <Aero-Tec3> have any of you done much deep hole drilling?
[20:19:32] <KimK> Ha, I'm even less a reprap guy than I am a lathe guy, but sure, reprap is interesting.
[20:20:00] <Aero-Tec3> thought you were a wheel on the reprap IRC
[20:20:20] <Aero-Tec3> see you there allot, or used to
[20:20:48] <PetefromTn> yeah done quite a bit of drilling in the lathe..
[20:21:02] <Aero-Tec3> so drilling with a lathe, pecking
[20:21:14] <KimK> Oh, I hang around lots of places. "You can observe a lot just by watching." --Yogi Berra
[20:21:38] <Aero-Tec3> is it better to do deeper pecking to start and then less deep per peck the deeper it gets?
[20:22:12] <Aero-Tec3> I worry about drill heating
[20:22:29] <Tom_itx> are you doing a full retract during peck cycle?
[20:22:39] <Aero-Tec3> when doing deeper holes the drill gets hot enough to boil water
[20:22:44] <Aero-Tec3> yes
[20:23:01] <Tom_itx> maybe you need drills with coolant holes
[20:23:14] <Aero-Tec3> boils my coolant I am using
[20:23:23] <Aero-Tec3> $$$$$$$
[20:23:25] <Aero-Tec3> ouch
[20:23:27] <Aero-Tec3> lol
[20:23:38] <Aero-Tec3> would be nice
[20:24:24] <Aero-Tec3> can you get 0.35 drill bits with coolant holes?
[20:25:00] <syyl_> 0.35mm?
[20:25:03] <Aero-Tec3> drilling about 2.25 to 2.5 inch deep
[20:25:06] <Aero-Tec3> inch
[20:25:31] <syyl_> about 8,9mm
[20:25:32] <KimK> Yes, that sounds like a good idea. I've seen some rules around for different divisions/types of deep hole drilling. Something like up to 5 times dia is shallow and you peck it *this* way, up to 10 times dia is medium and you peck it *this* way, up to x20 is deep, *this way, over x20 is very deep, *this* way. Something like that anyway.
[20:25:38] <syyl_> sure you can get it with trough cooleant
[20:26:06] <Tom_itx> maybe you need a different method for cutting the holes
[20:27:16] <Aero-Tec3> 7.14 times
[20:27:24] <syyl_> and if you gundrill, you just pop the drill in ;)
[20:27:39] <Aero-Tec3> I am open to suggestions as to making holes
[20:28:07] <Aero-Tec3> gun drill would be nice
[20:28:23] <Aero-Tec3> not a option right now but maybe latter
[20:28:25] <KimK> I don't think you can peck too much, especially if you've only got one drill bit.
[20:28:44] <KimK> Or one workpiece
[20:29:04] <syyl_> agree on that
[20:29:10] <Mikegg> evening gents, anyone here using an EMCO pc 55 mill?
[20:29:35] <Aero-Tec3> it is a stepped hole
[20:30:16] <skunkworks> just a emco pc5...
[20:30:21] <Aero-Tec3> .125 for the last, but drilled when the part is being finished on back end
[20:30:48] <skunkworks> Mikegg: http://groups.yahoo.com/group/CAD_CAM_EDM_DRO/message/99766
[20:31:18] <Aero-Tec3> 7/16 for about .75 to .9 inches
[20:31:43] <Aero-Tec3> then 0.35 for about 2.25 inches
[20:32:09] <Mikegg> haha badass
[20:33:19] <Aero-Tec3> other then gun drill any other suggestions for making this hole?
[20:33:51] <Aero-Tec3> would be cool to do a stepped gun drill
[20:34:42] <Mikegg> I was wondering if folks like the machines. I've used one of their little trainer CNC lathes. It was kinda cute. Spotted a mill at auction in my area...
[20:35:47] <PetefromTn> Aero-Tec3: What material?
[20:36:28] <Aero-Tec3> 416 ss and 12L14
[20:36:50] <Aero-Tec3> 5/8th up to 1.25 inch dia
[20:40:47] <PetefromTn> Honestly those holes are not all that deep, I would just recomment some good cutting fluid or flood coolant and a QUALITY drill bit and tap as typical. I typically try to run stainless a little deeper and harder because it work hardens so easily that the more you rub it the more the chance it will heat up on you. Much of this depends on the power of your lathe too. I'd probably drill the deep hole and then switch to a boring
[20:40:48] <PetefromTn> tool for the wider hole.
[20:41:32] <Mikegg> could you EDM it?
[20:42:54] <Aero-Tec3> if I had EDM, but slow, also not sure of cost
[20:43:17] <Aero-Tec3> so over heating could be to slow a feed?
[20:44:38] <Tecan> https://en.wikipedia.org/wiki/Quadrupole_mass_analyzer
[20:46:43] <Aero-Tec3> was using 0.005 per rev feed for 0.338 drill
[20:46:52] <Aero-Tec3> 500 RPM
[20:49:04] <AR_> so if i have a thread mill that is for "1/4-20 or finer"
[20:49:30] <AR_> i could mill a 1-16 thread with it, right?
[20:51:05] <Aero-Tec3> as for motor 2 HP so tons of power for this work
[20:51:06] <PetefromTn> Try slowing the speed of the spindle and increasing the peck depth slightly and see how that goes. Also might try searching Deep drilling in Stainless Steel on Practical Machininst.
[20:51:33] <Aero-Tec3> I was playing with the numbers
[20:52:10] <Aero-Tec3> 0.005 PR feed is only 0.0025 per cutting edge
[20:52:15] <Aero-Tec3> way to low
[20:56:45] <Aero-Tec3> just checked a program and it is saying that is to high
[20:57:37] <Aero-Tec3> 0.00172 PR and 294 RPMs
[21:17:11] <Aero-Tec3> I have a belt lathe and would like to not have to change speeds with every tool change
[21:17:38] <Aero-Tec3> would running faster or slower be the best way to go?
[21:31:20] <TekniQue> depends on the material
[21:31:38] <Aero-Tec3> 416
[21:31:38] <TekniQue> if it's the stainless you mentioned above, a slower speed will cover more tools
[21:32:03] <Aero-Tec3> what about running carbide at slower rates
[21:32:09] <Aero-Tec3> will it kill it?
[21:32:25] <Aero-Tec3> most of my tooling is carbide
[21:33:59] <Tom_itx> carbide doesn't mind the heat
[21:34:09] <Tom_itx> stainless will work harden if you're not careful
[21:34:47] <Aero-Tec3> so running carbide at slower RPMs on a lathe will heat things up?
[21:34:59] <Aero-Tec3> thought it would be cooler
[21:35:25] <Tom_itx> i don't think it would
[21:39:30] <Aero-Tec3> more heat going into cutter?
[21:40:13] <Aero-Tec3> not enough cutting past the cutter to cool it
[21:40:22] <Aero-Tec3> cuttings
