[00:10:59] <L84Supper> anyone heard the plan for the next LiveCD? Still Ubuntu or?
[00:13:26] <andypugh> I have heard nothing, but I would be surprised if it wasn't Ubuntu
[00:14:11] -!- Tom_L has quit []
[00:15:41] <L84Supper> what would be the first choice for a non official distro for Linuxcnc? Gentoo or?
[00:16:49] <andypugh> I have no opinion
[00:17:33] <L84Supper> that's what we ended up building
[00:18:01] <L84Supper> just didn't want to deal with gnome3
[00:19:49] <cpresser> L84Supper: just install another window manager
[00:19:57] <cpresser> thats what apt is for :)
[00:21:24] <L84Supper> how do the devs get accurate info from the Ubuntu devs, whenever we ask they just about ban us
[00:21:40] <andypugh> I doubt that they do.
[00:21:47] <L84Supper> or we get the "why do you need that?"
[00:23:23] <L84Supper> andypugh, btw all that searching for steam recovery equipment and then they decide on the worst solution next to boxing the steam and carrying it away by wagon train

[00:23:49] hans is now known as hans_r
[00:25:39] <andypugh> Sadly I am not surprised.
[00:25:53] <L84Supper> I have to check out that steam turbine co's factory next trip to China
[00:26:28] <andypugh> Have you any idea why they want to throw money away? Was it fear about reliability?
[00:27:32] <L84Supper> partially, and also someone to maintain it, they currently just let it go up into the air
[00:28:30] <L84Supper> thee must have been some EPA change since they were actually more concerned about filtering the <1% ethanol in the steam
[00:28:36] <L84Supper> thee/there
[00:30:57] <andypugh> So, they consider themselves a concret product plant whereas they ought to consider themselves a low-efficiency gas-powered power station with a sideline in concrete and gin.
[00:31:10] <L84Supper> :)
[00:32:03] <djdelorie> or an extremely low-efficiency still...
[00:32:09] <L84Supper> fiber cement products and backerboard
[00:32:38] <andypugh> djdelorie: That was the gin part
[00:33:40] <andypugh> Time to sleep. Hoping that I haven't actually bricked a full set of Mesa cards.
[00:33:49] <L84Supper> ouch
[00:33:52] <Tom_itx> oops
[00:34:04] <djdelorie> bricking is better than toasting

[00:35:39] <andypugh> That too.
[00:35:59] <L84Supper> at least the next set will be fine, what are the odds of bricking two sets in a row?

[01:12:28] <Tom_itx> no

[01:13:11] <Jymmm> 5/8 == 0.625
[01:13:42] <r00t4rd3d> i need to buy some digital calipers
[01:13:49] <Jymmm> 0.71875 == 23/32
[01:14:00] <Jymmm> .6875 11/16
[01:14:12] <Tom_itx> it's not metric either
[01:14:35] <Jymmm> I have to make a new card to include metric
[01:15:04] * Tom_itx looks over his shoulder at the chart
[01:15:14] <Jymmm> This one only does 64th's of an inch
[01:15:53] <Jymmm> next one will do 256
[01:16:01] <Jymmm> I hope
[01:16:22] <Tom_itx> nobody uses those
[01:16:44] <Jymmm> Maybe not, but my card does =)
[01:18:32] <Tom_itx> add cubits and span as well
[01:18:46] <Jymmm> It's what I needed to use to get all the fractions calculated out
[01:19:12] <Jymmm> if you saw the spreadsheet you would understand
[01:19:52] <Tom_itx> nice thing, my cad cam takes whatever i give it

[12:10:36] <anonimas1> how much does anyone know about rivets?
[12:11:33] <archivist> I know enough to do hidden rivets :)
[12:12:17] <anonimas1> hehe, how good are they stengthwise?
[12:12:33] <anonimas1> ie, bolting/riveting what's to perfer if i am to mount one thing to a aluminium profile

[12:13:10] <Jymmm> they do NOT prevent plumbers butt
[12:13:19] <anonimas1> well, theoretically it's better to drill a hole for a rivet then put a self tapping screw.
[12:13:53] <archivist> depends on the application, insufficient data for meaningful answer
[12:13:55] <Jymmm> anonimas1: can you elaborate on what you want to do?
[12:14:22] <anonimas1> i want to stick a towing point onto a aluminium profile.
[12:14:37] <anonimas1> without increasing the risk of stress cracks forming at the mounting points.
[12:15:01] <archivist> car towing point?
[12:15:18] <anonimas1> similiar
[12:15:46] <Jymmm> anonimas1: how about less elusive
[12:16:02] <archivist> do the maths for strength, de-rate for vibration and life
[12:16:05] <anonimas1> a mounting bracket for some equipment
[12:16:28] <archivist> old rule of thumb, 5 times
[12:16:49] <Jymmm> Even LESSER elusive, we dont care if this your sex toy thingy
[12:16:54] <anonimas1> what i really wanted to know, does that work in practice..
[12:17:24] <archivist> anything works in practice if well made and strong enough
[12:17:24] <Jymmm> it holds planes up in the sky
[12:17:25] <anonimas1> Jymmm: a parachute mount..
[12:17:35] <anonimas1> or something
[12:17:43] <gene77> JTshop: I just edited face.py to add the full path to my nc_files directory. It works now to write a file.
[12:17:51] <Jymmm> anonimas1: in plane or on a camera or a person?

[12:18:53] <Jymmm> free falling?!
[12:19:11] <anonimas1> yes..
[12:19:14] <Jymmm> If you can distribute the load as much as possible, sure
[12:19:44] <Jymmm> they even have air rivet guns
[12:21:22] <Jymmm> you might have to make a reinforced bracket
[12:21:41] <Jymmm> that will distribute the load
[12:21:55] -!- paideia [[email protected]] has joined #linuxcnc
[12:24:59] <anonimas1> yep, that's what im contemplating.
[12:25:07] <Tom_itx> Ti
[12:25:32] <Jymmm> anonimas1: google images "parachute mount"
[12:25:44] <anonimas1> Jymmm: it's not really a parachute mount but it's a structural thing
[12:25:56] <Jymmm> maybe you dont have to as much as we think
[12:26:08] <anonimas1> problem is not really the load as much as the mounting points and the limited space for mounting them
[12:26:24] <anonimas1> and threads into a al profile of 2mm is asking for problems with stress concentration
[12:26:42] <Jymmm> anonimas1: google images "parachute mount" and yooull see what i mean
[12:27:16] <archivist> us a nut on the other side dont thread thin ally
[12:27:38] <anonimas1> it's a closed profile
[12:28:08] <Tom_itx> how are you gonna buck a rivet if it's a closed profile?
[12:28:25] <Jymmm> blind rivet
[12:28:28] <anonimas1> blind rivet.

[15:09:42] <syyl> i will try that pretreadted steel, maybe its good for my needs
[15:10:09] <syyl> i want to bypass the problems that occur with heat threating in the homeshop...
[15:10:12] <syyl> like warping
[15:10:18] <archivist> yup I make a blank, cut on the gear cutter, then back on the lathe under a microscope to turn
[15:10:45] <syyl> cool :o
[15:10:51] <archivist> .2 mod iirc
[15:11:50] <archivist> hss for the gear cutter too, dont remember sharpening that over the 50 off I made

[17:05:32] <L84Supper> uw: I was looking for the same thing at Design Week, low cost just good enough ball screws for low duty consumer applications
[17:06:01] <L84Supper> there seem to be a void in that manufacturing space
[17:06:03] -!- Thetawaves [[email protected]] has joined #linuxcnc
[17:07:32] <uw> L84Supper, hey i was looking on ebay, but i dont really trust those chinese ones to be any good
[17:08:03] <jdh> how good do you need them to be? How cheap?
[17:08:16] <uw> i might just buy them though to give them a try
[17:08:48] <jdh> I paid $200 for 3 ballscrews/nuts for my mill, with machined ends, including shipping.
[17:08:57] <uw> jdh, i was looking the the C3 range
[17:09:01] <L84Supper> the problems might be soft steel or lack of QC
[17:09:02] <uw> hey thats not bad really
[17:09:34] <uw> jdh, do you have a recommendation for where to get them? or, where did you get yours?
[17:09:58] <L84Supper> other than they have the same machine tools in China s they do anywhere else
[17:10:34] <uw> L84Supper, well the whole QC thing is what i mean by "trust"
[17:10:47] <jdh> they are just rolled screws. Got them from linearmotionbearigns2008 or wtf his name is
[17:11:41] <uw> how long were they?
[17:11:51] <jdh> G0704 sized.
[17:12:11] <jdh> what about china?
[17:12:15] <jdh> <urk>
[17:13:06] <uw> i bought a spindle for my bigger mill from some china seller and the thing was garbage
[17:14:08] <uw> but i guess it was precision as you can get, if all you have is an 80grit bench grinder
[17:14:10] <L84Supper> yeah, that's why it's best not to pay up front
[17:15:12] <jdh> I have no complaints for mine. For $200 shipped, I'm more than happy.
[17:16:04] <L84Supper> http://www.ebay.com/sch/linearmotionbearings2008/m.html
[17:16:28] <uw> jdh, what mill did you end up putting it on?
[17:16:35] <uw> sorry to bombard you with questions...
[17:16:42] <jdh> a G0704
[17:18:24] <uw> ah ok. i saw that above but thought that was a legenth or something that i wasnt familiar with
[17:24:50] <IchGuckLive> L84Supper: 3 ballscruws no bit 62USD

[17:46:48] <IchGuckLive> 1/100 woudt give me 40000 resolution
[17:47:40] <archivist> most seem to be 90-1
[17:48:19] <archivist> relates to degrees for the manual types
[17:48:42] <archivist> higher ratio is better for accuracy
[17:48:45] <IchGuckLive> agree this gives a nice scale
[17:49:13] <IchGuckLive> and a 0.01 Degree resolution
[17:49:33] <archivist> I have seen some bad worm rotary devices, nearly .7 degrees error

[20:01:40] <Connor> wtf.. all the 3 port's are 1/8" not 1/4" :(
[20:01:51] <jdh> on what?
[20:01:57] <Connor> valves..
[20:02:22] <jdh> doesnt' matter, but shoudl be easy enough to find 1/4
[20:02:44] <jdh> I'd get npt->push-on fittings anyway
[20:03:06] <Connor> that's fine.. but still need a valve with 1/4" not 1/8"
[20:03:20] <jdh> why
[20:03:35] <Connor> cause I'm using 1/4" ? :)
[20:04:01] <jdh> tubing? hose? hard pipe?
[20:04:07] <Connor> hose.

[20:09:14] * jdh smacks connor
[20:10:04] <Connor> that one looks good.. but says Operating pressure 22-116 PSI, Max PSI 174
[20:10:14] <Connor> I'll be in the 120-140PSI range..
[20:10:33] <jdh> I'd guess 145 out of the box
[20:11:00] <Connor> I plan on putting a normal regulator in series so i can dial it down..
[20:12:07] <Connor> So, I'm guessing with they say operating PSI.. if you exceed that amount.. it won't trip.. but the housing is rated for much higher..
[20:12:43] <jdh> should be balanced
[20:13:08] <Connor> what do you mean ?
[20:13:30] <jdh> it should open regardless of pressure. The valve is balanced on both sides.
[20:14:51] <jdh> I just got my 5th a2z 12% off email

[20:18:11] <andypugh> How is it possible to make that for that price?
[20:19:09] <jdh> currency held arificially low, low labor costs, cheap materials?
[20:19:52] <andypugh> Talking of eBay, my Lemo connectors came in today. I appear to have somehow ordered a size 0B plug with 5 pins and a size 1B socket with 4 pins. How annoying.
[20:20:15] <jdh> 0b is tiny?
[20:20:34] <andypugh> Not as small as 00
[20:20:52] <andypugh> 0B is merely "compact"
[20:21:18] <jdh> when you are done, you need a new project for the 'wrong' connector.
[20:21:31] <andypugh> The widest part is 9.5mm dia
[20:22:22] <Connor> That has 5 ports...

[20:23:57] <jdh> you are going to power-retract the cylinder also?
[20:24:12] <Connor> I have 3 ideas on that.
[20:24:18] <jdh> uh oh
[20:24:33] <jdh> that's 2 too many, or 1 short.
[20:24:43] <Connor> Idea #1: Use a valve like this. But that means it's always under pressure..
[20:25:18] <Connor> Idea #2: Use 2 separate valves. Could be 2 of these with the B side plugged..
[20:25:43] <Connor> Idea #3: Put low pressure in the retract stage and leave it pressurized all the time.
[20:26:12] <jdh> it needs to vent also.
[20:26:30] <Connor> Which one?
[20:26:45] <Connor> Idea #3 ?
[20:27:02] <jdh> and 2.
[20:27:12] <Connor> No. Just put a 10-20 PSI in it.. Turns it into a air spring
[20:27:24] <Connor> idea 2, if I use 2 valves, they'll have vents.
[20:27:41] <jdh> maybe.
[20:28:22] <Connor> I played with Idea 3 already.. I put some air in the retract side.. just a little.. then hit the extend side and it worked fine..
[20:28:29] <Connor> now, how much force I lost? I dunno.
[20:28:48] <Connor> Most likely, I'll go with Idea 2
[20:29:25] <Connor> thoughts ?
[20:29:27] <jdh> where does the air in the cylinder/line go, after you release the solenoid and it closes.
[20:30:01] <Connor> which method ?
[20:30:29] <jdh> any of them.
[20:30:56] <jdh> will the valve self-vent when you let it go off.
[20:31:02] <Connor> okay, on retract, 1 of the stages has a vent, the other two have ports.. one of which has a "vent filter"
[20:31:26] <Connor> when you release the valve they have a vent.
[20:31:26] <jdh> aren't those just on the other side of the piston(s)?
[20:31:44] <Connor> yes.
[20:32:20] <jdh> the air in the side you just pressurized is still pressurized. Where is it going to vent?
[20:33:33] <jdh> or does that 3 way valve vent out the other port.
[20:33:50] <jdh> I think I have confused myself and should go home.
[20:34:34] <Connor> The valve has 2 states. 1 state feeds the outlet with air from the inlet. the other state shunts the air from the outlet to the vent port.
[20:35:03] <Connor> So, the valve has a vent.
[20:36:42] <Connor> in the case of the one you linked.. it's designed to hookup to one of those cylinders I have.. and will keep one side, or the other pressurized. (Port A, Port B) vents out R and S.. and P is the Supply I belive.

[21:29:14] <jdh> I was thinking of a venting problem on a machine... I walked by on the way out. The solenoid fed a regulator. The solenoid valve vented fine, the reg didn't
[21:29:17] <Connor> now, to just figure out, if they list operating pressure at 116PSI, what happens if I run it at 130-145
[21:30:06] <uw> it will become a mini grenade?
[21:30:17] <Connor> No. It's rated for 178PSI
[21:30:28] <andypugh> There are two sorts of regulator, relieveing and non-relieving.
[21:30:42] <gene77> probably not, but it may well hang

[21:43:34] <JT-Shop> hmmm using cutter diameter comp my ball is coming out 0.0312" too big... which is the diameter of the tip
[21:43:43] <delkin> Hi everyone. When I run a 'G01' the speed of the spindle is defined with 'F'. What about the 'G00'?
[21:44:01] <jdh> delkin: whatever your max speed is
[21:44:06] <andypugh> archivist: The guys a lunatic!
[21:44:19] <delkin> jdh, how do I define the max speed?
[21:44:32] <andypugh> delkin: The _spindle_ is always defined by S
[21:45:16] <JT-Shop> I wonder if the lathe tool table really wants the nose radius not the effective diameter
[21:45:58] <andypugh> It ought to be able to work it out by setting a very big radius and running a G41
[21:46:00] <JT-Shop> sure is purdy though
[21:46:06] <andypugh> (look at the preview)
[21:46:09] <archivist> andypugh, I get bored after making a few tools
[21:46:29] <delkin> andypugh: But before I call the 'S' command with the max speed, I should call the 'G96', right?
[21:46:29] <JT-Shop> hows that andypugh?
[21:46:50] <Connor> one that can do 116 should be good.. I'll have it at around 100 to 110.. Looks like I can get 2000lbs from 100
[21:47:10] <delkin> andypugh: otherwise will be interpreted as rev/min
[21:47:17] <delkin> am I right?

[21:47:42] <delkin> :)
[21:48:08] <JT-Shop> delkin: S only applies to RPM mode
[21:48:20] <JT-Shop> I think
[21:48:40] <andypugh> No, it sets surface speed too.
[21:48:53] <JT-Shop> only on the same line?
[21:49:01] <Connor> http://www.modvid.com.au/html/body_anders_bike_shop_details.html
[21:49:04] <Connor> Is that for real ?
[21:49:07] <JT-Shop> It is an error if:
[21:49:07] <JT-Shop> S is not specified with G96
[21:49:08] <andypugh> G0 and G1 have no effect on spindle speed though.
[21:49:17] <Connor> I do model trains.. I have to say.. holy cow..
[21:49:26] <andypugh> Connor: Seems to be
[21:50:34] <Connor> Something about it just doesn't look right..
[21:50:54] <andypugh> JT-Shop: It is, you specify surface speed with S, and max RPM with D.
[21:52:52] <Tom_itx> JT-Shop did you try my code?
[21:53:32] <Tom_itx> the tool path is calculated from the nose radius center and offset the tool radius amount

[21:54:03] <JT-Shop> Tom_itx: no, it had an error with using a Y offset
[21:54:31] <JT-Shop> I put the tool radius in the tool table and the part is closer to proper size still a tad big...
[21:54:37] <Tom_itx> using G96 the S word isn't spindle speed rather surface speed and D is the rpm
[21:54:53] <Tom_itx> what sort of error?
[21:54:56] <Tom_itx> y offset?
[21:55:12] <Tom_itx> mmm there should be no y in that
[21:55:12] <JT-Shop> trying to use a y offset in the G18 plane
[21:55:35] <JT-Shop> in G18 only I and K are valid offset words
[21:55:43] <Tom_itx> yes i fixed that one
[21:55:50] <Tom_itx> err no
[21:55:56] <Tom_itx> that was a different K
[21:56:03] <Tom_itx> that was supposed to be J instead
[21:56:07] <Tom_itx> on an arc move
[21:57:28] <delkin> JT-Shop: G20\n G96 D2500 S250\n implies 2500 rev/min and 250 feet/min. G00 is going to use 250 as speed value, right?
[21:57:55] <Tom_itx> i believe so if i read it right
[21:58:01] <Tom_itx> in surface feet
[21:58:17] <Tom_itx> which is rather fast
[21:58:51] <andypugh> hang on, I have my lathe head on
[21:59:09] <JT-Shop> delkin: G96 has nothing to do with your rapid speed
[21:59:22] <Tom_itx> i wish someone would post a working lathe file (gcode) i'd work on my template some more
[21:59:22] <andypugh> I am not sure that G96 has any meaning at all in a mill config.
[21:59:29] <JT-Shop> the D2500 means max speed of the spindle
[21:59:32] <Tom_itx> andy it doesn't
[21:59:41] <JT-Shop> delkin: did you read the link?
[21:59:47] <Tom_itx> it's about constant feed with the spindle rpm vs work diameter
[22:00:02] <Tom_itx> and you'd better have an upper limit set on your spindle too
[22:00:10] <delkin> hmm.. :\
[22:00:18] <Tom_itx> with an automatic bar feed you can rip it off the floor if you don't
[22:00:23] <delkin> So, how do I configure the G00 speed?
[22:00:34] <Tom_itx> it's your max limits in your hal file

[22:06:03] <Tom_itx> that's alot of flippin gcodes at the top :)
[22:08:19] <andypugh> Tom_itx: All the lathe G-code I ever use:
http://www.bodgesoc.org/lathe/
[22:09:21] <Tom_itx> the thing about the lathe is you have at least a couple feed modes to account for
[22:09:33] <Tom_itx> depending if you're using G96 or not
[22:09:51] <andypugh> I always work CSS and feed per rev. Nothing else makes mush sense
[22:10:22] -!- odogono has quit [Read error: Connection reset by peer]
[22:10:37] <Tom_itx> so your feed per rev would typically be something like .005" or so
[22:10:48] <Tom_itx> depending what you're doing of course
[22:11:06] <andypugh> It's nearly always 0.15mm or 0.03mm for parting
[22:11:28] <andypugh> I occasionally crank it up when I am getting bored.
[22:11:39] <Tom_itx> does linuxcnc provide an upper spindle limit for lathes?
[22:11:43] <Tom_itx> i assume it does
[22:12:06] <Tom_itx> beside the normal spindle speed max
[22:12:17] <andypugh> Not that I know of, but it will be inherent to the system. (PWMgen scale, VFD settings, etc)
[22:12:21] <Tom_itx> you can set an upper spindle speed per job
[22:12:43] <andypugh> Well, the D in g96 does that
[22:12:44] <Tom_itx> it would make sense to have one with varying diameter materials

[22:23:42] <Jymmm> I got it to a) drag someone out of the water, and b) decend from a 2nd story if SHTF
[22:24:10] <Tom_itx> you can survive a 2 story jump
[22:24:38] <Jymmm> Well, 3rd or 4th story as I used to work on the 4th floor
[22:25:31] <Jymmm> but I'd rather have an escape bag for that, but kevlar is $$$
[22:25:50] <Tom_itx> prolly why i have none
[22:26:00] <Jymmm> ditto
[22:26:01] <Tom_itx> don't really need it either
[22:26:07] <Jymmm> nope
[22:26:25] <Jymmm> that s why I have the 100ft of 3/8" =)

[22:26:36] <Tom_itx> i've since quit climbing trees for the most part
[22:27:08] <Jymmm> Well, I figured in a pinch I can use the biners as pulleys
[22:27:27] <Jymmm> instead of ripping the crap out of the rope
[22:27:30] <Tom_itx> i got a figure 8 but never use it
[22:27:38] <Tom_itx> and a decender
[22:27:41] <Tom_itx> somewhere
[22:27:56] <Jymmm> If I found a cheap fig 8 I'd get it.
[22:28:03] <Jymmm> used, yard sale, etc
[22:28:24] <Jymmm> I found a neat knot for decending though
[22:28:36] <Jymmm> without a fig 8
[22:29:10] <DaViruz> the munter hitch?
[22:29:20] <Jymmm> DaViruz: Double munter hitch
[22:29:54] <Tom_itx> ok i should go mount this encoder plug to my control box
[22:30:04] <DaViruz> oh, never heard of
[22:30:05] <Jymmm> have fun
[22:30:10] <Jymmm> DaViruz: hang on
[22:30:11] <DaViruz> i see, it can't reverse
[22:31:22] <DaViruz> http://www.smarttravelinfo.com/the-munter-friction-hitch/
[22:31:38] <DaViruz> it seems the main purpose is to compensate for thinner rope?
[22:32:12] <Jymmm> http://www.youtube.com/watch?v=pawzQsoqaqk
[22:32:35] <Jymmm> I think just for better control
[22:33:17] <andypugh> I am not overly-fond of the figure8, it basically makes rebelays part-way down impassable as you find a tangle of rope there
[22:33:35] <Tom_itx> what are those continuous loop webbing called.. like 1/2" or so wide?
[22:33:47] <Tom_itx> i got a bunch of those for tying off stuff
[22:33:58] <andypugh> Though we did once abseil using a manhole cover lifter to replace the bulb in a security light :-)
[22:33:58] <Tom_itx> different lengths
[22:34:00] <Jymmm> sewn webbing
[22:34:05] <Tom_itx> yeah
[22:34:06] <DaViruz> they're called a sling here at least
[22:34:17] <andypugh> tap sling
[22:34:21] <andypugh> tape, even

[22:38:06] <gmagno> erm... you guys know of any gcode parser in python?
[22:38:13] <DaViruz> especially when your neighbour gets on your nevers
[22:39:51] <andypugh> gmagno: What do you expect a "parser" to do?

[22:41:14] <gmagno> andypugh, I mean memory
[22:42:01] <andypugh> I think I have seen something that visualised G-code in Python.
[22:43:17] <andypugh> In fact, might "gremlin" do what you want?

[22:53:29] <gmagno> andypugh, that seems something very dependent on linuxcnc libs
[22:53:46] <andypugh> Yes, there is that
[22:54:02] <andypugh> You didn't say that that would be a problem.
