[00:00:03] <dgarr> tjtr33: what is your video -- $ lspci |grep VGA
[00:00:12] <tjtr33> Toby44 just the location of the command in the gcode might do 1st line =turn on digital output (im exhausting ) 2d line = wait digital input (im done)
[00:00:20] <tjtr33> dgarr will check
[00:00:34] <furrywolf> http://promariner.com/products/waterproof-on-board-marine-battery-chargers/promar1-series/ a real brand... but the actual device shipped does not match the specs on the web page or in the manual.
[00:02:01] <furrywolf> I spent good money on this charger specifically because it had dimensions suitable for replacing my old charger. instead, it's larger, and doesn't fit.
[00:02:13] <tjtr33> dgarr lspci |grep VGA intel 82Q35 rev 2
[00:02:26] <furrywolf> I really should just give up and become one of those people who refuses to buy anything made in china or taiwan.
[00:02:38] <tjtr33> dgarr i tried vga=791 w/o luck on grub line
[00:02:54] <tjtr33> w/o better luck )
[00:03:25] <tjtr33> furrywolf, 'finely made in Taiwan' its their motto
[00:04:40] <tjtr33> dgarr, dont worry bout it till i collect so useful info. thx for looking into it

[00:09:02] <tjtr33> Topy44, look at http://linuxcnc.org/docs/html/gcode/m-code.html#sec:M62-M65 and M66 (iirc)

[00:10:35] <Topy44> tjtr33: but that requires those codes to be inside the gcode file, which means that if a job is cancelled the exhaust will never be turned off
[00:10:52] <tjtr33> mdi the off command
[00:10:57] <furrywolf> probably typical chinese crap - they changed suppliers and didn't update the manual, for a product they had no part in designing anything on but the label.
[00:11:24] <Topy44> tjtr33: huh?
[00:11:52] <tjtr33> issue M66 in the mdi screen, that turns it off ( or m67, look at the manual )
[00:13:12] <Topy44> well yeah, but the point is that its done automatically whenever the machine is stopped
[00:13:42] <tjtr33> got to go, you can make a btn and program the connection, as you like
[00:13:49] <zeeshan-mill> do you guys
[00:13:53] <zeeshan-mill> put a flat on end mills
[00:13:56] <zeeshan-mill> along the wholelength ?
[00:14:04] <zeeshan-mill> for indexable end mills
[00:14:51] <furrywolf> now I need to decide if I want to use this charger, which would require fabricating a new mounting bracket (not complex but not trivial either - a couple brake bends and a bunch of drilling), or buy from another company.
[00:15:43] <furrywolf> it's also annoyingly thicker, and would stick out the side
[00:18:48] <furrywolf> I figure on crap when I buy ebay shipped-from-china stuff, but I wanted this to fucking WORK, so I bought from a major brand for real money... and it's still crap.
[00:26:12] <furrywolf> bbl, errands

[00:30:34] <tjtr33> dgarr, i turned off audio irqs and all usb irqs, then i played an mp3 and _heard_ it very faint thru headphones, then i plugged in a thumb drive for the screenshots, and was able to store the pix. This means the irqs (at least) dont do what i thought they did.

[01:53:34] <PCW> if they are a diff pair you shouls only get ~3..5V or -3..-5v never close to 0
[01:53:48] <PCW> should
[01:54:31] <PCW> (if thats what you mean by matched set)
[01:56:42] <PCW> otherwise a couple LEDs and slow shaft turning will de-mystify them

[02:01:56] <MacGalempsy> I have the axis off the machine, so maybe it would be best to just open up the housing and test out the leads

[02:37:30] <zeeshan-mill> im not going to recycyle it through the machine
[02:37:32] * cpresser is a console-guy. i like doing stuff manually
[02:37:36] <zeeshan-mill> not worth it for me

[02:56:51] <adam3999> anyone having issues with the parallel port in their J1900 motherboards?
[02:57:21] <adam3999> i noticed that i can't get any inputs in LinuxCNC or with the ptest HAL application
[02:59:10] <Cromaglious_> argh... can't find the page with the spindle on off for the yoocnc nt65
[02:59:19] <micges> adam3999: yes I saw this problem too
[02:59:28] <Topy44> sorry for repeating myself, but again:
[02:59:39] <Topy44> is there a hal pin or such that tells me if a job is running?
[02:59:58] <adam3999> micges: any resolution? i tried all of the parallel port modes in the BIOS...
[03:00:01] <micges> Topy44: halui.program.is-running
[03:00:12] <Topy44> thanks!
[03:00:31] <micges> adam3999: I don't know current status, it was some time ago when I saw first report
[03:00:55] <Topy44> actually searching for that also gave me the list of pins i was looking for :)
[03:01:15] <adam3999> micges: thanks, do you by chance remember where it was posted? linuxcnc forum?
[03:02:38] <micges> adam3999: iirc it was on some Polish forum
[03:02:54] <adam3999> hmm ok thanks
[03:03:05] <micges> adam3999: pm
[03:03:55] <adam3999> practical machinist forum?
[03:04:02] <Tom_itx> is there an issue with the parallel port on the J1800s? i'm considering getting one and would plan to use it...
[03:04:22] <adam3999> not entirely sure, i have an Asrock Q1900M
[03:04:26] <micges> adam3999: read private message
[03:04:30] <adam3999> the latency is very low and board has lots of features
[03:04:49] <micges> and is cheap
[03:04:53] <adam3999> yep
[03:05:00] <adam3999> i've had no issues milling with it
[03:05:09] <adam3999> i just can't get any inputs from my leadshine MX3660
[03:05:20] <PetefromTn_> anybody watch the new Hawaii 5-o?
[03:05:32] <adam3999> i ended up shorting a few input pins right to ground directly on the parallel port header on the motherboard, no dice
[03:06:40] <adam3999> the motherboard is also very low wattage, i've got the whole thing running on 12V 4A standby power from a 48V server power supply
[03:07:02] <adam3999> with SSD and fans
[03:07:08] <micges> adam3999: cnc.info.pl
[03:08:32] <micges> Tom_itx: there is problem with geting input from epp port to lcnc
[03:09:27] <micges> I've got this on desk, everything works and etc, just simply inputs are 0 all the time
[03:09:45] <micges> I had*
[03:11:30] <Tom_itx> well i've already got a working D525 but pcw indicated the J1800s were alot better
[03:11:52] <Tom_itx> and i'm up for a new board
[03:12:20] <Tom_itx> but not with a defective parport
[03:12:55] <Topy44> btw, anyone using linuxcnc on a beagleboard or other small embedded system?

[03:13:05] <Tom_itx> those two i'm looking at
[03:13:07] <Topy44> i have been thinking to switch our system over
[03:13:31] <Tom_itx> just deciding if i need PCI or not
[03:13:39] <Topy44> sorry, beaglebone i mean
[03:13:44] <adam3999> tom: yep, Q1900M is what i have. works great beside this one issue
[03:14:15] <adam3999> large issue, heh...
[03:14:22] <Tom_itx> parport is a big issue for me
[03:16:21] <Tom_itx> adam3999, which board do you have?
[03:16:35] <adam3999> the asrock you posted in the 1st link -- Q1900M
[03:16:50] <micges> Topy44: if you want to use beaglebone then machinekit is your option
[03:17:06] <Topy44> just reading up on machinekit, not entirely sure...what it is :)
[03:17:17] <Tom_itx> iirc it's cheaper than the D525 was at the time
[03:17:47] <Tom_itx> i wouldn't _have_ to use it for lcnc but it would be the purpose for getting it
[03:18:16] <Tom_itx> it has pcie that will fit the newer pcie cards doesn't it?
[03:18:38] <Tom_itx> my D525 has pcie but i don't think i can fit a card to it
[03:19:35] <adam3999> http://www.cnc.info.pl/topics54/linuxcnc-na-j1900b-vt61463.htm
[03:19:46] <adam3999> yeah these folks are discussing the issue on page 5 of the thread
[03:20:03] <adam3999> he's trying to run a linear encoder back to linuxcnc and the inputs on his J1900 motherboard aren't working
[03:20:23] <Tom_itx> straight to the parport?
[03:20:31] <Tom_itx> i'd be using a mesa card on mine
[03:20:44] <adam3999> not clear to me from the conversation
[03:20:49] <Tom_itx> i wonder if that's the difference between working or not
[03:21:00] <Tom_itx> pcw has been testing one i think
[03:21:15] <adam3999> if you're using a mesa to replace the parallel port i would think this is a non-issue
[03:21:30] <Tom_itx> i've got parport mesa cards currently
[03:21:50] <adam3999> i was hoping to avoid that for now since i can get more than adequate rapids with just the integral parallel port and rtlinux pulse generation

[03:22:12] <Tom_itx> the 7I90 seems like a nice board for that so far
[03:22:25] <Tom_itx> cheaper than the previous 7i43 i had
[03:22:33] <Tom_itx> with more io
[03:22:41] <pcw_home> I'll test the EPP on Monday on the J1800, Seems to me it worked but its been a while
[03:23:08] <Tom_itx> i was gonna try that pcie board but i don't think it will fit on my D525
[03:23:45] <pcw_home> not easily
[03:23:45] <micges> adam3999: it seems that's kernel issue, under linuxcnc on debian wheezy they say it works
[03:23:46] <Tom_itx> the card lays over on it's side and there's little room for it
[03:24:16] <adam3999> micgres: interesting, i converted the 2.6 live iso to a USB drive and installed that
[03:24:30] <adam3999> is wheezy newer or older than the 2.6 live disc?
[03:24:47] <adam3999> i never followed debian releases...

[03:26:27] <adam3999> right
[03:26:34] <MacGalempsy> Ok. on this plug there is a loop that connected to the board, but nothing on the device. on a 4th axis, would it be good to set up a condition that if the loop is complete that the 4th axis is installed?
[03:26:35] <adam3999> it looks like the 2.6 iso is wheezy
[03:27:03] <Tom_itx> i'm running 2.6 on lucid right now
[03:27:26] <Tom_itx> and yes the iso is wheezy

[03:36:24] <XXCoder> I now recall your cool animation
[03:36:24] <zeeshan> it grips on that thing and pulls around 3000lb
[03:36:36] <zeeshan> the mechanism that does that is called the drawbar
[03:36:44] <zeeshan> in cnc machines its a power drawbar
[03:36:44] <XXCoder> cool thanks
[03:36:53] <zeeshan> in manual machines its a threaded rod
[03:36:56] <zeeshan> that you tighten down
[03:37:05] <XXCoder> i did use mill thats been converted to cnc, it has power drawbar
[03:37:15] <XXCoder> while other one just uses this very long bolt
[03:39:20] <XXCoder> dunno whats its called
[03:39:35] <XXCoder> it screws into chuck and as its tightened it grips whatever tool
[03:39:49] <zeeshan> thats a manual drawbar
[03:39:49] <XXCoder> or hand releasable chuck (chucks all way down?)
[03:39:55] <adam3999> same thing, drawbar that usually pulls up a collet
[03:40:02] <XXCoder> collet oops
[03:40:07] <zeeshan> oh
[03:40:15] <XXCoder> collet vs chucks?
[03:40:15] <roycroft> any spindle with a taper steeper than about that of a morse taper is incapable of supporting the collet
[03:40:16] <zeeshan> yea thats a collet chuck
[03:40:20] <roycroft> or chuck
[03:40:21] <roycroft> or whatever
[03:40:36] <XXCoder> how much wood would chuck chuck?
[03:40:41] <XXCoder> :P sorry bit in silly mood
[03:40:44] <roycroft> a machine with a b&s taper or morse taper doesn't need a drawbar
[03:40:49] <roycroft> but anything steeper does
[03:41:08] <XXCoder> cool. been playing with solvespace
[03:41:10] <XXCoder> its amazing
[03:41:17] <XXCoder> who first bought it up here?
[03:45:51] <XXCoder> if I use show infereing parts, how do I hide it so I can adjust?
[03:50:57] <XXCoder> completed second tutorial

[04:00:09] <tjtr33> zeeshan, this uses a pneumatic sleeve to _release_ the balls from the neck groove of the pull stud.
[04:00:14] <tjtr33> theres no drawbar and the release of air clamps back using bellville washer springs to seat the tool. 5000 N force!

[05:09:51] <zeeshan> bobo_: that is cool
[05:10:04] <zeeshan> that looks like a compact
[05:10:06] <zeeshan> custom ball bearing
[05:10:13] <zeeshan> to support a serious amount of radial load
[05:11:06] <zeeshan> so when that collar compresses
[05:11:12] <zeeshan> the balls release from the gripper
[05:11:15] <zeeshan> i mean pull stud
[05:12:20] <tjtr33> tbat photot is the worm ring and the die set bearing that guides the up/down motion of the cylinder.

[11:27:53] <MacGalempsy> question. this allen bradley manual for the VFD says the current rating is 10mA maximum. does that mean any input higher than 10mA will burn it up?
[11:29:21] <archivist> max is a "safe" limit
[11:29:48] <MacGalempsy> 10mA seems pretty small
[11:29:59] <archivist> anything above reduces reliability
[11:31:43] <MacGalempsy> there are 3 inputs that have a 10mA max. should I get a 10mA powersupply and use a relay ?
[11:32:57] <archivist> keep within the voltage spec and you likely cannot go over the current spec
[11:33:18] <archivist> the input resistance will be sensible
[11:35:56] -!- micges has quit [Quit: Ex-Chat]
[11:38:08] <MacGalempsy> ok, so if I use the same 24v power supply for field power to power the I/O on the VFD, then it should be ok?
[11:39:16] <archivist> we can only know yes no is we have read the vfd manual
[11:40:43] <MacGalempsy> the note in the VFD manual states "Power for the I/O must be supplied by an external 12-24v VDC poewr source
[11:41:36] <MacGalempsy> I will use that to run to the I/O Power and I/O common

[16:53:07] <XXCoder> not rejected just stopped
[16:53:31] <archivist> alex4nder, finish is a rigidity problem
[16:53:51] <alex4nder> archivist: ah, then I guess I'll find out
[16:54:11] <archivist> different can of worms
[16:55:43] <archivist> .00033 parallel over your span, is what you are measuring and that can change under load
[16:56:25] <alex4nder> yah, I'm already seeing measured flex when torquing fasteners with a DTI in the spindle
[16:56:35] <archivist> you can test that by having the dti in contact and pressing on the top of the spindle housing
[16:56:44] <alex4nder> exactly
[16:57:31] <archivist> it is why industrial machines have huge box columns
[16:58:37] <ssi> archivist: I have this goofy finish problem:
[16:58:38] <ssi> https://pbs.twimg.com/media/B8yC4T8IQAA81K2.jpg:large
[16:58:57] <ssi> and I guess it's cause I'm cutting that with a loooong 5/8" endmill
[16:59:17] <archivist> and it was noisy as hell
[16:59:18] <ssi> the one on the right was done with the world's dullest 4-tooth non center cutting endmill, and it took ages
[16:59:21] <ssi> yeah
[16:59:32] <ssi> the one on the left was done with a fresh sharp 3-tooth endmill
[16:59:46] <archivist> chatter and vibration, bending of the tool and machine
[17:00:21] <ssi> is there any way to improve it in that scenario tho?
[17:01:06] <archivist> also you can try climb (digs in) and conventional (pushes tool out)
[17:01:20] <ssi> well side cutting doesn't work for crap
[17:01:24] <ssi> so I have been plunge cutting it
[17:01:25] <archivist> climd needs much more rigidity
[17:02:37] <archivist> climb gets a better finish if the machine and tool is up to the job else terrible
[17:02:40] <alex4nder> ssi: I ran into a similar problem when milling deep pockets in a 80% .. object.
[17:02:47] <ssi> lol
[17:02:57] <archivist> conventional can eat the chips
[17:02:59] <ssi> I've cut fire control group pockets before with no problem
[17:03:51] <alex4nder> I ended up writing a trochoidal milling plan, and going to a smaller endmill
[17:04:03] <alex4nder> and just managed my engagement that way

[17:05:20] <archivist> Sandvik make some extendable milling tools for deep work
[17:05:40] <ssi> I don't see how that could be more rigid

[17:09:21] <archivist> part of the capto range I think
[17:11:53] <archivist> trick it to be as close to the walls with as large a diameter mill on the end of the extension
[17:13:09] <ssi> I see
[17:13:11] <archivist> its working again http://www.sandvik.coromant.com/en-gb/knowledge/milling/application_overview/profile_milling/application_checklist/pages/default.aspx
[17:13:14] <ssi> sounds expensive :)
[17:13:43] <archivist> or make your own :)
[17:15:29] <archivist> so make an old style lathe round boring bar but shove it in the spindle of the mill
[17:15:50] <ssi> boring bar might actually work well
[17:16:22] <archivist> some fiddling needed but cheap
[17:22:04] <zeeshan> i like that diagram
[17:22:07] <zeeshan> showing point milling
[17:22:59] <archivist> ssi some of the sandvik extensions have damping, you could wrap your bar in some soggy mass (lead)
[17:23:07] <ssi> lol
[17:23:16] <archivist> or use tubing with lead in
[17:24:03] <archivist> play with your rake too

[17:38:38] <furrywolf> >90% RH outside (the highest my weather station reads), 70% RH inside
[17:39:23] <zeeshan> at least its not stupid cold

[17:39:36] <zeeshan> :-)
[17:39:46] <zeeshan> i know the answer
[17:39:51] <zeeshan> :D
[17:40:01] <zeeshan> at first look i was like 'wtf'
[17:40:34] <furrywolf> ... which way is the tool moving? if to the left, it's smearing, not cutting, and has no rake..
[17:40:49] <zeeshan> you can tell which way its moving
[17:40:51] <zeeshan> by the chip curl
[17:40:54] <furrywolf> or no edge, or something
[17:41:07] <furrywolf> it's mushing, not cutting. lol
[17:41:16] <zeeshan> thats how chips are formed..
[17:41:21] <zeeshan> but theres something wrong with the chip :P
[17:41:42] <zeeshan> the chip thickness has to be larger than the feed
[17:41:48] <zeeshan> (feed is the depth of cut in this pic)
[17:42:45] <furrywolf> I guess it's on a different scale than I was thinking.
[17:43:29] <furrywolf> I was thinking it was a deep cut with a very blunt tool.
[17:48:40] <archivist> it has negative rake, which is a bit silly for a lot of metals
[17:49:08] <zeeshan> cutting geomtry is fine
[17:49:13] <zeeshan> we don't know the base metal
[17:49:21] <zeeshan> so we can't comment on whether that is good or bad
[17:49:29] <archivist> sure you can
[17:49:38] <zeeshan> we dont even know if this is some silly fragile cutting tool material
[17:49:49] <zeeshan> that does require a negative rake to increase the tip strength
[17:50:09] <zeeshan> how can you tell what the work piece material is?
[17:50:34] <archivist> because we dont know the material we also cannot know why the simulation is wrong!
[17:50:40] <zeeshan> you can
[17:50:42] * furrywolf decides it's a butter knife cutting tofu
[17:50:48] <zeeshan> chip thickness has to be larger then
[17:50:55] <zeeshan> the chip feed
[17:51:01] <furrywolf> what if the material is compressable?
[17:51:07] <zeeshan> due to conservation of plastic deformation
[17:51:18] <zeeshan> conservation of volume in plastic deformation
[17:51:36] <archivist> you should watch some of the youtube slomo cutting vids
[17:51:53] <zeeshan> i have
[17:51:58] <zeeshan> my prof made a few of those :P
[17:52:19] <archivist> you dont know the speed of the chip v base so cannot know the volume
[17:52:38] <zeeshan> you dont need to
[17:52:42] <zeeshan> the depth of cut in that pic
[17:52:44] <zeeshan> is the feed
[17:52:50] <zeeshan> youre looking at 1 snap shot
[17:52:55] <zeeshan> so feed isn't a function of time
[17:52:59] <zeeshan> its just a distance
[17:53:19] <furrywolf> cutting wood on a lathe is quite common. wood is compressable. I don't see how you make any assumptions on the chip size.
[17:53:28] <archivist> I know, the speed of the vertical chip could be twice the cut feed
[17:53:36] <zeeshan> furrywolf: the course is called metal cutting
[17:53:37] <zeeshan> not wood cutting

[18:33:51] <Swapper> i have tried net estop-out hm2_5i25.0.7i77.0.0.output-07
[18:34:18] <archivist> an input?
[18:34:31] <zeeshan> swapper you mean
[18:34:32] <Swapper> the e-stop input works
[18:34:43] <zeeshan> when you press the e-stop button in linuxcnc
[18:34:45] <zeeshan> it does an e-stop?
[18:34:51] <Swapper> i whant linuxcnc to be able to trip my external e-stop chain
[18:34:57] <Swapper> that kills the main contactor
[18:34:58] <zeeshan> okay
[18:35:29] <Swapper> im using loadrt estop_latch
[18:35:36] <Swapper> that i found in a wiki

[18:36:26] amnesic is now known as amnesic_away
[18:37:51] <Swapper> zeeshan: it does do a e-stop but its only "soft" e-stop since it kills the enable signals only
[18:37:55] <Swapper> not the powerfeed
[18:38:08] <zeeshan> i honestly didnt give power to linuxcnc to do a full e-stop
[18:38:22] <zeeshan> it having control over enables was good enough
[18:38:34] <Swapper> ok maybe im overdoin it
[18:38:34] <zeeshan> and 7i77 drops sets all outputs to low
[18:38:39] <zeeshan> if the clock fails

[18:39:16] <Swapper> atleast then the power goes out if i close linuxcnc

[18:41:34] <Swapper> ok
[18:41:44] <zeeshan> use e-stop sparingly! :P

[21:14:02] <zeeshan> anyone need fadal pull studs? :D
[21:14:07] <cradek> I have done that many times
[21:14:16] <Computer_Barf> I would imagine it would be important to recover the chips
[21:14:21] <cradek> http://timeguy.com/cradek/01408982148
[21:14:31] <zeeshan> cradek
[21:14:33] <zeeshan> that looks great
[21:14:43] <cradek> nah, sterling is cheap as (unusually expensive) dirt
[21:15:15] <cradek> if you did a ton of it, sure, but for an occasional one-off I have never bothered to figure out who will do the recovery for me
[21:15:29] <cradek> zeeshan: thanks! it turned out really nice.
[21:15:47] <Computer_Barf> I would think if you put it in a small graphite crucible and hit it with propane you could make bead
[21:16:03] <Computer_Barf> that piece looks very nice , good work
[21:16:17] <cradek> sure you could make it back into a blob if it was very clean
[21:16:53] <cradek> I made sterling glasses frames, and I milled the hinge parts
[21:16:57] <cradek> no pics, sorry
[21:17:49] <cradek> what's your project?
[21:17:56] <Computer_Barf> ive been kind of depressed lately about the cost of cam software
[21:18:46] <alex4nder> Computer_Barf: you tried out hsmexpress for solidworks or invetor?
[21:18:47] <alex4nder> +n
[21:18:48] <Computer_Barf> I'm building a cnc'd g0704 , I'm getting ready to pull the trigger on the electronics portion as I already have the mechanical stuff
[21:19:04] <alex4nder> also fusion360 has it integrated into their web version now
[21:19:11] <Computer_Barf> well I keep trying to get myself a copy of solidworks
[21:19:19] <ssi> too bad fusion360 seems to be a turd
[21:19:34] <alex4nder> ssi: what's wrong with it?
[21:19:36] <Computer_Barf> I would really like to get bobcad because eventually I am going to add more axis's
[21:19:41] <ssi> it's laggy as hell
[21:20:12] <Computer_Barf> I just don't have 3 something grand for solidworks
[21:20:20] <cradek> I've never heard a single good word about bobcacd
[21:20:29] <ssi> lol
[21:20:41] <alex4nder> I tried fusion 360 on my mac, and it seemed ok
[21:20:55] <ssi> it hasn't been particularly ok for me
[21:21:06] <ssi> also everyone keeps talking about a free startup version but mine doesn't have that option
[21:21:08] <Computer_Barf> well perhaps you could recommend one that I can expand into 4th, 5th axis later
[21:21:29] <zeeshan> who buys software
[21:21:32] * zeeshan hides
[21:21:35] <TTN> lol
[21:21:35] <ssi> lul
[21:21:38] <TTN> tried freecad?
[21:21:52] <zeeshan> isn't buying software for big corporations :)
[21:22:17] <TTN> get the latest version you can find. something higher or equal to v0.14
[21:22:21] <ssi> I have no problem buying software so long as it's good and priced sanely
[21:22:33] <zeeshan> the pricing on real cad software
[21:22:38] <zeeshan> isn't for average joe..
[21:22:43] <ssi> right
[21:22:45] <zeeshan> i really think only businsses can afford that
[21:22:56] <zeeshan> like solidworks student license is like $120
[21:22:56] <Computer_Barf> yes I have no problem buying software when It's actually possible for me
[21:23:00] <zeeshan> which i think is cheap
[21:23:01] <Computer_Barf> but damn some of the prices
[21:23:06] <zeeshan> vs their 5000 real license
[21:23:19] <alex4nder> zeeshan: 99% of what I do can be expressed conversationally, so I eneded up writing ghettoCAM
[21:23:28] <Computer_Barf> yeah.. im not a student though..
[21:23:32] <zeeshan> you can be
[21:23:37] <zeeshan> its easy :p
[21:23:50] <Computer_Barf> you mean, just saying you are a student?
[21:24:05] <zeeshan> you can take a life training courses
[21:24:09] <zeeshan> and pay like 500 bux a year
[21:24:10] <zeeshan> haha

[21:24:34] <zeeshan> obvously if youre using the software to generate money
[21:24:40] <zeeshan> you should follow their license rules
[21:25:18] <zeeshan> i once went to a machine shop which i wll obviously not name
[21:25:22] <zeeshan> that had a dedicated computer for cad and cam
[21:25:24] <zeeshan> with no internet
[21:25:32] <zeeshan> i was curious why there was no internet
[21:25:41] <zeeshan> :-)
[21:25:51] <ssi> your mom has no internet
[21:25:54] <zeeshan> thats pretty illegal!
[21:25:59] <zeeshan> your face!
[21:26:03] <zeeshan> ssi
[21:26:07] <zeeshan> i forgot what i was going to build this weekend
[21:26:08] <zeeshan> fak.
[21:26:15] <ssi> come help me build things then
[21:26:15] <zeeshan> i was so excited to build it too
[21:26:16] <zeeshan> haha
[21:26:17] <Computer_Barf> I tried getting solidworks torrents , seems cracks just arn't what they used to be.
[21:26:18] <ssi> hurry up
[21:28:01] <zeeshan> ssi
[21:28:03] <zeeshan> you come help me
[21:28:12] <zeeshan> i think ill work on the car today
[21:28:16] <ssi> ugh boring
[21:28:30] <zeeshan> you know whats boring
[21:28:32] <zeeshan> your fACE
[21:28:37] <zeeshan> go back to mr cool guy plane building
[21:28:39] <ssi> it's not boring
[21:28:41] <ssi> it's more like repulsive
[21:28:45] <ssi> but t hat's interesting at least
[21:28:51] <zeeshan> haha
[21:28:58] <zeeshan> dude i mentioned im gonna work on cars
[21:29:03] <zeeshan> and all the sudden i smell burning oil smell
[21:29:04] <zeeshan> in my noise
[21:29:07] <zeeshan> *nose
[21:29:11] <zeeshan> damn cars.
[21:29:15] <ssi> I hate when my noise smells like oil
[21:29:26] <ssi> I think I got epoxy in my eye
[21:29:34] <zeeshan> eek
[21:29:46] <Computer_Barf> If I plan on moving into 4th and 5th axis as I progress, what CAM should I seek?
[21:29:54] <ssi> 5th axis will never be cheap

[21:49:45] <zeeshan> http://www.maritool.com/images/PS-4E-0110-2.jpg
[21:49:48] <zeeshan> i want to do this..
[21:50:00] <zeeshan> it honestly looks like they just drove a hex head cap screw inthere
[21:50:01] <zeeshan> lol
[21:50:09] <alex4nder> yah
[21:50:14] <Jymmm> zeeshan: if you look at the points very closely, you'll see they are rounded
[21:50:25] <zeeshan> so they actually went in there
[21:50:27] <zeeshan> with a small end mill
[21:50:31] <zeeshan> and cleaned up the corners after drilling?
[21:50:43] <Jymmm> or just press ushed it
[21:50:54] <Jymmm> or molded it
[21:51:41] <zeeshan> i think flats makes sense..
[21:52:07] <Jymmm> whats that thing... berch tool
[21:52:07] <zeeshan> it just sucks cause youll likely need a crowfoot
[21:52:14] <zeeshan> to get torch wrench on it
[21:52:50] <Jymmm> think like a socket wrench
[21:52:56] <Jymmm> or allen screw
[21:52:56] <JT-Shop> I would never make pull studs
[21:52:58] <zeeshan> it wont fit
[21:53:09] <zeeshan> JT-Shop: why
[21:53:15] <Jymmm> zeeshan: are you trying to make a tool or part?
[21:53:23] <zeeshan> im trying to make the pull stud
[21:53:31] <JT-Shop> I don't have the proper heat treat oven and testing lab
[21:53:38] <zeeshan> i do

[21:55:25] <zeeshan> pull studs dont look like sorcery
[21:55:30] <zeeshan> mari tool and retention knob use 8620
[21:55:35] <zeeshan> which is case hardenable steel
[21:55:42] <zeeshan> so they keep the skin hard, the internal ductile

[21:56:06] <zeeshan> they'll use ultra high strength tool steel
[21:56:26] <zeeshan> and then theres the fancy pull studs by daishowa which is h13 with rolled threads
[21:56:39] <zeeshan> at the end of the day its just 3600 lb of force
[21:56:51] <zeeshan> if you have a factor of safety of 4 or 5
[21:56:53] <zeeshan> it should be safe enough
[21:57:28] <FinboySlick> zeeshan: Would it too hard to rotary-broach?
[21:58:46] <zeeshan> FinboySlick: im not sure, never tried making a hex before

[22:05:06] <Jymmm> JT-Shop: Pile up the EPS into a mound. VERY VERY QUICKLY... Grab a laytex balloon or disposable glove and fill with 8 ounces of acetone. Inflate just slightly, tie tight and place on EPS mound and run like hell
[22:05:22] <Jymmm> HAve video camera on tripod running ahead of time
[22:07:07] <zeeshan> JT-Shop: keep it!
[22:07:13] <zeeshan> use it for shipping packages
[22:07:17] <Jymmm> EPS = Expanded polystyrene = Sytrafoam
[22:07:34] <JT-Shop> a seed bag full

[22:08:02] <JT-Shop> a bag that sunflower seeds come in
[22:08:20] <Jymmm> 5" x 5"
[22:08:55] <Jymmm> anyhow, semantics... just try what I said

[22:13:15] <JT-Shop> https://www.youtube.com/watch?v=h9Jx8NRkWTo
[22:13:44] <JT-Shop> so what do you do with the crosslinked polystyrene residue
[22:14:42] <Computer_Barf> I wonder one might get plate stock of sterling silver
[22:14:50] <Jymmm> Dude, it's not the destination, but the journey... If you put it into a baloon slightly inflated it's going to "spray' droplets and that will vary the "melting" effect on the EPS.
[22:15:36] <Jymmm> The acetone will eventually "pop" a laytex balloon

[22:16:44] <Computer_Barf> I save all my styrofoam takeout food trays,especially the black ones

[22:16:56] -!- BellinganRoy has quit [Quit: Konversation terminated!]
[22:17:07] <Jymmm> If you can spray paint the foam withoutmelting it, when the acetone hits it, it'll flow like goo
[22:17:11] <Computer_Barf> the black pigment will go a long way to turn the white ones black
[22:17:17] <Jymmm> noce high contrast
[22:18:14] <Computer_Barf> 4-5 black ones will mix with probably 100 white ones to make a black blob of polystyrene
[22:19:46] <Computer_Barf> when you dry the polystyrene though it does tend to bubble up a bit. You can mill shapes from it but it is more of a ridged foam board, I've made shelf brackets with it
[22:20:15] <Computer_Barf> it would be nice to know the secret to drying it into solid plates without the acetone expanding internally and creating bubbles
[22:20:19] <pcw_home> dissolve in acetone and then knead in potassium chlorate...
[22:20:35] <Computer_Barf> what will that do
[22:20:59] <Jymmm> pcw_home: Is that before or after the exothermic reaction?
[22:21:56] <Jymmm> pcw_home: and you forgot the sulfur ;)
[22:22:05] <Computer_Barf> I've considered perhaps making a steel reaction vessel , then adding a semi saturated acetone polystyrene batch, and then injecting steam to distill off the acetone

[22:23:27] <Jymmm> pcw_home: dont forget the charcoal too
[22:23:48] <Computer_Barf> i know sometimes they make little round polystyrene balls from adding hexane to pellets and then putting them in a heated blower chamber in which they expand
[22:24:01] <Computer_Barf> then they compress all the balls into polystyrene blocks
[22:24:16] <Computer_Barf> so hexane expansion
[22:25:09] <renesis> who still uses foam boxes?
[22:25:09] <Jymmm> pcw_home: I wanted into a local hardware store. On the shefl was 10lbs of sulfur, next to it was 20 lbs of ‎Potassium nitrate, and on the floor was a pallet of about 200 lbs of charcoal =)

[22:27:25] <dirty_d> yea, it works on linux well now
[22:27:30] <dirty_d> it was kinda screwed up before
[22:27:37] <renesis> woah
[22:27:47] <zeeshan> if anyone is interested in how i got my tool changer to work

[22:27:51] <renesis> my school has a 300 level plant science class Intro to Wines
[22:28:03] <renesis> 21 and over
[22:28:44] <dirty_d> actually fmt_mm and fmt_in wont work now, but it wont hurt to use it
[22:29:05] <dirty_d> renesis, it works a lot better than freecad
[22:29:21] <renesis> freecad was a bit worse than draftsight when i used it
[22:29:27] <Swapper> pcw_home: are there any maximum length on the 25 dsub cable between 6i25 and 7i77 ?
[22:29:38] <zeeshan> tool changer is COOL
[22:30:02] <dirty_d> thats a big machine
[22:30:06] <Tom_itx> zeeshan lemme see
[22:30:08] <dirty_d> what is it?
[22:30:18] <CaptHindsight> NX, ProE, Catia, ......................................... solvespace, freecad
[22:30:34] <dirty_d> renesis, freecad would be great if the important stuff actually worked
[22:30:36] <zeeshan> talking to me?
[22:30:43] <dirty_d> like linking sketches to external geometry
[22:30:51] <dirty_d> zeeshan, about the big machine yea
[22:30:54] <CaptHindsight> I think NX has a Linux version

[22:31:35] <renesis> dirty_d: ya
[22:32:01] <dirty_d> looks expensive
[22:32:14] <renesis> it would work okay for awhile and then when enough time was invested, it would crap out on some simple essential feature
[22:32:25] <renesis> like, bitch let me offset without crashing
[22:32:34] <dirty_d> yea, its mostly due to going back and editing sketches that others depend on
[22:32:45] <dirty_d> edges get renamed internally and it breaks relationships
[22:32:45] <FinboySlick> zeeshan: It's a very nice machine. Love the scraped surfaces.
[22:32:54] <renesis> like, heirarchial blocks?
[22:33:15] <dirty_d> renesis, like if you make a sketch, extrude it, then map a sketch to one of the faces
[22:33:16] <pcw_home> Swapper: 15 feet is about the maximum, if you want more you are better off with a Ethernet card like the 7I92
[22:33:22] <dirty_d> all is well and good until you go back and edit the first sketch
[22:33:30] <dirty_d> then the second explodes
[22:33:32] <renesis> yeah thats not cool
[22:33:46] <dirty_d> that seesm to be working really good in solvespace
[22:34:24] <dirty_d> the way this is written is kinda annoying to work with, its like c++ thats trying to hard to be C
[22:35:18] <dirty_d> std:: doent appear once in the source
[22:35:34] <dirty_d> and if you do include a c++ header, it breaks all the macros that are all over the place
[22:35:41] <Swapper> pcw_home: ty
[22:36:02] <Swapper> that would do it.
[22:37:17] <zeeshan> does home depot carry socket head cap screws?
[22:37:31] <zeeshan> i need an 8-32
[22:37:41] <zeeshan> for some reason my collection goes from 6-32 to 10-24 10-32
[22:37:42] <CaptHindsight> zeeshan: maybe just in SS
[22:37:42] <zeeshan> lol
[22:37:52] <zeeshan> thatll work
[22:38:01] <CaptHindsight> I seem to avoid HD for that reason when fastener shopping
[22:38:13] <zeeshan> i only go there in a bind
[22:38:18] <zeeshan> usually try to go to my supplier reglover
[22:38:36] <CaptHindsight> I just started buying bulk off ebay
[22:38:47] <zeeshan> same its cheaper to buy a box
[22:38:51] <zeeshan> for 50/100
[22:38:53] <CaptHindsight> whole boxes for $2-3
[22:38:56] <zeeshan> vs buying 10 bolts
[22:39:19] <CaptHindsight> in China you buy by the Kg
[22:39:24] <alex4nder> anyone know which kernel Tormach went with for Path Pilot?
[22:39:24] <renesis> i think they carry down to #8 or #6
[22:39:30] <renesis> they wont have small stuff
[22:39:31] <CaptHindsight> they just have bins, no boxes
[22:39:47] <renesis> and yeah its specialty drawer stuff
[22:39:52] <renesis> they wont have a ton
[22:40:37] <CaptHindsight> whenever I go to HD or Menards for fasteners they are always out of the exact size I need

[22:42:01] <zeeshan> why?
[22:42:06] <zeeshan> ss galls

[23:19:58] <pcw_home> On the other hand a Preemt-RT kernel is easy to build
[23:20:17] <alex4nder> yah, it's more telling that the -rt dev work has stalled
[23:20:26] <XXCoder> man
[23:20:29] <XXCoder> been busy all day
[23:20:35] <XXCoder> van works pretty lot better
[23:21:18] <XXCoder> it actually warmed up in 6 minutes
[23:21:28] <XXCoder> pretty impressive for van with dead termostat
[23:24:05] <XXCoder> before it wouldnt warm up even if you sent it to sun :P
[23:25:16] <pcw_home> 3.18 just released so not really stalled
[23:27:26] <XXCoder> I guess not all that much demend for realtime
[23:27:41] <alex4nder> pcw_home: reading about the lack of funding, and seeing the lack of updates, makes me think different
[23:28:15] <pcw_home> have you looked recently?
[23:28:20] <alex4nder> yah, I just did
[23:28:24] <pcw_home> busier than ever
[23:28:53] <pcw_home> even Xenomai 3 is based on -rt
[23:31:07] <zeeshan> so i inspected the mari tool pull studs
[23:31:29] <zeeshan> they're quite far out from tolerance
[23:31:34] <zeeshan> (in my opinion)
[23:32:07] <zeeshan> for example, the stem diameter is supposed to be .986" from din standard
[23:32:16] <zeeshan> theirs is .980"
[23:32:27] <zeeshan> theyre making this on a cnc machine
[23:32:33] <zeeshan> not sure why the undersize?
[23:32:44] <XXCoder> odd
[23:33:02] <XXCoder> your stuff tested for accuracy?
[23:33:09] -!- robinsz has quit [Read error: Connection reset by peer]
[23:33:32] <zeeshan> .828" theirs
[23:33:36] -!- robinsz [robinsz!~robin@88.97.63.122] has joined #linuxcnc
[23:33:36] <zeeshan> standard .831
[23:33:45] <zeeshan> no im comparing their stuff to standard
[23:33:53] <XXCoder> ahh ok
[23:33:56] <zeeshan> im trying to make my own pull studs
[23:33:57] <JT-Shop> what's the tolerance on the standard?
[23:34:13] <pcw_home> Preemt-rt 3.18.rt2 running on a a laptop (3 hours of videos etc)
[23:34:14] <pcw_home> http://ibin.co/1tGDqozK5zse
[23:34:16] <pcw_home> not bad for a laptop... the stock preemt-rt kernel with wheezy is useless (800000 latency)
[23:34:45] <zeeshan> on the standard .986 diameter, the tolerance is -.006
[23:34:54] <zeeshan> so they meet the tolerance
[23:34:58] <zeeshan> just under small size :P
[23:35:03] <XXCoder> barely
[23:35:22] <zeeshan> i mean with cnc you can hold .001 pretty easily
[23:35:41] <XXCoder> wonder if their operator screwed up
[23:35:49] <zeeshan> im not trying to sound negative or anything
[23:35:57] <zeeshan> just comparing :)
[23:36:06] <JT-Shop> that has happened as well as the programmer screwing up
[23:36:06] <zeeshan> maybe
[23:36:15] <zeeshan> or the tool is worn out
[23:36:20] <zeeshan> in the sense that its got a built up edge
[23:36:24] <zeeshan> so now its machining undersize
[23:36:31] <XXCoder> oh
[23:36:52] <XXCoder> was abou to ask "wouldnt it mean oversize not under"
[23:36:58] <zeeshan> like for the .986 dimension, +.000 -0.006
[23:37:05] <zeeshan> what would you guys program your target dimension to be ?
[23:37:08] <zeeshan> midway? :)
[23:37:17] <XXCoder> closert o max
[23:37:24] <XXCoder> you cant recut negative distance
[23:37:30] <zeeshan> good point
[23:37:35] <zeeshan> but if youre confident in your machine
[23:37:39] <zeeshan> holding +/-0.001
[23:37:53] <XXCoder> yea probably -.002
[23:38:02] <zeeshan> fair enough
[23:38:08] <XXCoder> still closer to max but any over varation wont go over
[23:39:31] <zeeshan> wow
[23:39:41] <zeeshan> the length of the gripping portion of th estud
[23:39:44] <zeeshan> is out of tolerance by a lot
[23:40:24] <XXCoder> whats tol and how much is it over
[23:40:46] <zeeshan> nominal length .984", +0.008 -.000 , inspection dimension: .994"
[23:41:21] <zeeshan> out by 2 thou
[23:41:29] <XXCoder> ow
[23:42:16] <zeeshan> still works! :P

[23:45:01] <zeeshan> honestly, the best quality stuff
[23:45:06] <zeeshan> is the stuff you work on your own
[23:45:09] <XXCoder> other site says 9 mil for paper
[23:45:11] <zeeshan> regardless of made in taiwan, made in usa.
[23:45:34] <zeeshan> japanese stuff is amazing cause there is so much pride in their work
[23:45:41] <zeeshan> the work the car guys do there
[23:45:43] <zeeshan> is crazy
[23:45:51] <zeeshan> XXCoder: i guess paper varies a lot
[23:45:55] <XXCoder> yeah
[23:46:12] <renesis> xxcoder: is all about rice paper rolling papers for setting z
[23:46:16] <renesis> .001"
[23:46:31] <XXCoder> I tend to use thinner notepad paper
[23:46:34] <XXCoder> tend to be fine
[23:46:46] <zeeshan> i use aluminum foil
[23:46:50] <renesis> yeah that stuff is like 3-4 mil
[23:47:02] <XXCoder> sometimes I even use regular paper if its not very precise job
[23:47:11] <renesis> i just measure whatever im using
[23:47:19] <XXCoder> foil is 3-4 mil?
[23:47:28] <XXCoder> .003-4?
[23:47:33] <renesis> notebook paper
[23:47:37] <XXCoder> or .0003
[23:47:40] <renesis> foil is whatever it is
[23:48:03] <XXCoder> renesis: yeah I tend to use notebok a LOT so I try reuse written paper
[23:48:24] <renesis> its prob safer for the part
[23:49:15] <renesis> tho, part should be fine with anything if youre taking your time and stepping less than thickness of offset material
[23:49:47] <XXCoder> or just adjust down one thou after find z0
[23:49:53] <renesis> .001 is easy to remember and usually not too bad to ignore
[23:50:04] <XXCoder> how do you guys accurately find zero using face mill?
[23:50:09] <renesis> xxcoder: in axis you can set offset
[23:50:22] <renesis> itll pop up a window and you would enter .001 for rice paper
[23:50:29] <XXCoder> at one machine I always have to adjust down by .006 after find z0 using large face mill
[23:50:45] <renesis> or say -.05 for a .1" edge finder from the left
[23:50:46] <XXCoder> and thats after I confirm tooth I sued is lowest one
[23:50:53] <XXCoder> used
[23:51:39] <renesis> yeah i have spring collets so i have to set z every tool change unless PCB drills w/ collars
[23:51:54] <XXCoder> my router will use edge router
[23:52:00] <renesis> so tool table lengths dont matter because i dont use them
[23:52:01] <XXCoder> so yeah need touch em all off bah
[23:52:23] <renesis> yeah honestly its better your way once you have the shit set up
[23:53:06] <zeeshan> anyone have a source for a cat40
[23:53:07] <zeeshan> tool holder
[23:53:12] <zeeshan> i need the dimensions of the thread
