[00:06:10] <r00t4rd3d> i think thats referred to as a "shindig"
[01:23:22] <Jymmm> Lovely...
http://www.youtube.com/watch?v=aLxsLbl16IM&feature=g-yt
[01:27:43] <tjb1> Heh Jymmm that was a good laugh
[01:28:19] <Jymmm> Even worse (I think)...
http://www.youtube.com/watch?v=YNO-AzPxS4U&NR=1&feature=endscreen
[01:31:47] <tjb1> "How did the iPad get into your house?"
[02:05:20] <tjb1> Some dickhead on cnczone defending plasmacam like he has 85% share in it...
[02:06:57] <DJ9DJ> moin
[02:11:14] <tjb1> yeah its morning alright...
[02:11:15] <tjb1> 3am
[02:11:47] <DJ9DJ> 9am here :)
[02:12:05] <tjb1> http://www.gotorch.com/
[02:12:14] <tjb1> That looks strikingly similar to plasmacam...
[02:24:17] <tjb1> Where is a good place to buy wire online?
[02:24:25] <tjb1> I need something like 18/3 stranded
[02:24:47] <Jymmm> an extension cord?
[02:24:52] <Jymmm> ^outdoor
[02:25:32] <tjb1> 18 gauge
[02:26:10] <Jymmm> Yes, outdoor extensions cords are 18/3, as in 18ga three conductor stranded wire.
[02:26:50] <tjb1> Hmm, will check that out
[02:26:57] <tjb1> What If I want 24/3 :)
[02:27:09] <Jymmm> kiss my ass ?
[02:27:21] <tjb1> http://www.waytekwire.com/item/ST18-3/SHIELDED-CABLE-GRAY-PVC-JACKET/
[02:27:23] <tjb1> Ah beautiful
[02:27:58] <tjb1> Whoa, 500 ft min...
[02:29:04] <tjb1> Dont say Lowes either Jymmm, I was there tonight and made the guy spool the damn thing 4 times and they dont have anything on the panel they say they have
[02:30:07] <toastyde1th> monoprice?
[02:33:19] <tjb1> Nothin there that I seen in a smaller amount
[02:33:37] <tjb1> McMaster has some good stuff but its approaching $1 a foot
[02:33:45] <tjb1> for 18/3-24/3
[02:34:26] <tjb1> Continous flex cable ;)
[02:34:42] <toastyde1th> looks like you'll just have to man up and pay what the cable costs
[02:35:19] <tjb1> Looks like it :(
[02:35:30] <tjb1> or just complain to Lowes until they order what I want.
[02:36:32] <tjb1> Homing/limit sensors are just luxury items anyway, real men sit there with a hand on the e-stop
[02:37:19] <DJ9DJ> lol
[02:41:03] <tjb1> Well I guess a real man would just stall the machine out
[04:52:41] <alex_joni> howdy
[05:43:33] <jthornton> morning
[07:12:17] <JT-Shop> now that morning has arrived I have to plan two things, how and where
[07:16:32] <DJ9DJ> its already afternoon ;)
[07:23:47] <JT-Shop> then you should have all ready unloaded the surface grinder for me :)
[07:26:16] <JT-Shop> loaded up it is 4" lower than the garage door! this makes it easy to unload
[07:40:11] <r00t4rd3d> i do not like cbs news new site
[08:06:42] <JT-Shop> andypugh: this size grinder 8" x 1/2" doesn't need to balance the wheels according to the manual.
[08:37:24] <andypugh> That saves a lot of bother
[08:49:53] <JT-Shop> yes it does
[08:52:47] <Tom_itx> inertia at 8" at rpm probably isn't enough to split the wheel
[08:53:14] <Tom_itx> although it will shorten bearing life
[09:00:56] <JT-Shop> clearly some organizational work must preceed the off loading
[09:55:56] <r00t4rd3d> can anyone convert *.max files to dxf/stl/obj ?
[09:58:55] <alex_joni> r00t4rd3d: I thought 3DS max had an export for obj's
[09:59:04] <alex_joni> http://3dcodingtutorial.com/Working-with-3D-models/Exporting-the-model.html
[09:59:39] <r00t4rd3d> i dont have 3ds max
[10:00:22] * r00t4rd3d fires up the boat
[10:01:20] <alex_joni> http://superuser.com/questions/297031/is-there-any-free-way-to-convert-3ds-max-max-to-3ds-or-obj
[10:04:18] <r00t4rd3d> i want to start a new torrent site called somalia.com
[10:04:31] <r00t4rd3d> the name is available too lol
[10:04:49] <r00t4rd3d> aww no it isnt
[10:39:07] <skunkworks__> pcw_home:
http://bbs.homeshopmachinist.net/threads/55882-CnC-programs-Turbo-Mach3?p=798801#post798801
[10:39:10] <skunkworks__> yay
[11:23:55] <r00t4rd3d> bored
[11:23:57] <r00t4rd3d> http://i.imgur.com/QMMrF.jpg
[12:01:01] <JT-Shop> http://imagebin.org/230303
[12:03:05] <skunkworks__> nice - new?
[12:03:13] <JT-Shop> the gantry?
[12:03:24] <JT-Shop> the grinder is 1973
[12:03:31] <JT-Shop> new to me yes
[12:03:43] <skunkworks__> heh
[12:03:50] <skunkworks__> (that is what I meant
[12:03:59] <skunkworks__> automatic left/right?
[12:04:03] <JT-Shop> I know
[12:04:11] <JT-Shop> no manual with a micro feed on Z
[12:04:37] <skunkworks__> ah - looks like there is stops (ours has stops that set the 'x' travel limits
[12:04:41] <skunkworks__> hydraulic)
[12:04:57] <JT-Shop> yea it has stops on the X
[12:05:09] <JT-Shop> no room for a hydraulic in the shop
[12:05:28] <skunkworks__> heh - the thing is all self contained
[12:05:36] <JT-Shop> I used to run some flat belt driven grinders a long long long time ago
[12:05:45] <skunkworks__> I don't know what brand it is (old also)
[12:06:03] <JT-Shop> some have big hyd power packs that take up floor space
[12:06:57] <skunkworks__> right - the machine shop at work has one
[12:07:03] <JT-Shop> now I have to play musical chairs to fit it in
[12:07:26] <JT-Shop> I need to make room for the VMC anyway
[12:07:44] <JT-Shop> and get it moved in to this shop
[12:08:33] <JT-Shop> nap time now
[12:08:37] <skunkworks__> dad says our surface grinder is a brown and sharp also..
[12:09:02] <skunkworks__> (it does look slightly similar..)
[12:09:09] <JT-Shop> this one is a Brown and Sharpe 612 MicroMaster
[12:09:35] <skunkworks__> I don't think I have any pictures of ours
[12:15:30] <IchGuckLive> Hi all B)
[12:16:25] <IchGuckLive> Fox live till the last second
[12:45:13] <IchGuckLive> today we started corn Harvest here for the Bioenergie reactor 2100Tonns first Day nice job not linuxcnc powerd
[12:47:19] <IchGuckLive> im off tomorrow second day GN8
[13:25:11] <alex_joni> skunkworks__: hey sam
[13:25:45] <JT-Shop> hay alex
[13:29:32] <alex_joni> hey JT
[13:29:38] <alex_joni> all well on your side of the world?
[13:31:36] <JT-Shop> yes, just shoe horning in a surface grinder in the shop
[13:31:46] <JT-Shop> http://imagebin.org/230303
[13:31:55] <JT-Shop> how goes it on that side?
[13:34:07] <archivist> you can post that grinder over here if you dont have enough space
[13:34:10] <Loetmichel> nice lift.
[13:34:19] <Loetmichel> isnt that e bit weak sideways?
[13:34:29] <JT-Shop> no, it is very strong
[13:34:58] <mazafaka> manual mill?
[13:35:00] <Loetmichel> the small diagonals on the top are sufficient?
[13:35:02] <Loetmichel> i wonder
[13:35:03] <JT-Shop> I built it to maximum height for my shop but the clamps take up far too much room
[13:35:19] <JT-Shop> yea they are plenty strong as there is no side loads
[13:36:26] <mazafaka> oh, surface grinder
[13:36:30] <JT-Shop> the beam is 10' long and the diagonal plates are 18"
[13:36:54] <archivist> is that an expansion loop in the airline just where you dont need one
[13:37:20] <JT-Shop> that is an easy way to make the corner
[13:38:36] <JT-Shop> what a mess on my worktable
[13:39:31] <archivist> if there is no mess in a workshop then there is something wrong :)
[13:39:43] <mazafaka> exactly a mess, no excuse! :)
[13:41:01] <alex_joni> JT-Shop: all swell here
[13:41:06] <JT-Shop> I had a friend that had a shop that was white with cabinets and drawers all around and not a thing in sight... looked strange
[13:41:23] <alex_joni> heh
[13:41:31] <alex_joni> maybe it was a different kind of shop?
[13:41:32] <JT-Shop> cool how is the young one? getting big?
[13:41:34] <alex_joni> pharmacy?
[13:41:48] <JT-Shop> he messed with RC helicopters mostly
[13:41:59] <alex_joni> ah, the not messy kind of shop ;)
[13:42:17] <JT-Shop> no, made you afraid to touch anything
[13:42:38] <alex_joni> heh
[13:42:47] <alex_joni> well.. the shops I go to are similar
[13:42:52] <alex_joni> afraid to touch anything :))
[13:43:00] * JT-Shop has to move a 300lb anvil now :/
[13:43:04] <alex_joni> but the other way around.. you get too dirty :P
[13:43:33] <JT-Shop> some of the factories I go to are like that
[13:43:33] <Loetmichel> archivist: be careful whart you wish for...
[13:44:18] <Loetmichel> i am a "messie"... my workshop lokks like after a police raid :-)
[13:46:54] <mazafaka> JT-Shop: do you have orders from small factories as if you're an outsorcer?
[13:51:07] <archivist> Loetmichel, I know all about mess :)
[13:51:13] <JT-Shop> very seldom do I run parts, my main work is designing and build automation equipment
[13:51:56] <JT-Shop> from time to time I do small runs of things that the big boys charge too much for...
[13:54:58] <archivist> part of my mess is catalogued with locations and barcodes
[13:57:28] <JT-Shop> like the dewey decmil system?
[13:59:23] <archivist> I have dewey numbers for the books so finding all the gear type books is easy

[14:14:37] <Beginner_Gabe> Hello
[14:14:40] <mk0> is master now really 2.6.0~pre? after installation from master i get 2.5.0.
[14:15:13] <andypugh> mk0: How did you install Master?
[14:15:19] <andypugh> Beginner_Gabe: Hi
[14:16:05] <Beginner_Gabe> this is gabe_w i have this name because im on the lfs-support channel and i wanted to be clear that i was a beginner
[14:16:29] <andypugh> Ah, I did wonder.
[14:19:48] <Beginner_Gabe> i decided i can't go any further untill i really understand how linux works
[14:20:19] <Beginner_Gabe> i bought some books, and i have set aside the next two days to attempt to build a LFS, really for no the reason than to learn
[14:20:56] <mk0> andypugh, just like wiki said.
[14:21:12] <mk0> a, then added some files from psha
[14:21:20] <andypugh> From source? From Buildbot?
[14:21:28] <mk0> no, from git
[14:21:58] <andypugh> OK, in that case you need to . ./linuxcnc-dev/scripts/rip-environment
[14:22:36] <andypugh> You have both an installed 2.50 and a run-in-place 2.6, and you need to tell the system which one to run.
[14:23:02] <andypugh> (and I did mean to type dot space dot slash there
[14:24:31] <mk0> yes, . ./rip-environment, then ./linuxcnc - LINUXCNC - 2.5.0
[14:24:35] <mk0> no errors
[14:25:00] <andypugh> what does git branch say?
[14:25:19] <mk0> *trivkins-comp
[14:25:46] <andypugh> You created that branch?
[14:26:20] <mk0> nope. i at first cloned master from linuxcnc.org, then from psha trivkins-comp
[14:26:38] <andypugh> When you clone the git repository you get all the branches.
[14:27:00] <andypugh> Is seems likely that the psha branch is based on 2.5
[14:27:11] <andypugh> gitk might make it more clear
[14:27:25] <mk0> yep, if it can be, it is
[14:27:35] <mk0> i'll ask him tomorrow
[14:27:56] <andypugh> git branch presumably listed master and 2.5 (and others?)
[14:28:17] <mk0> yes
[14:28:52] <andypugh> I think you are running a modified 2.5. Which might be exactly what you want to do.
[15:16:52] <Beginner_Gabe> if i could physically hug linux i would... i can't believe i spent 10 years of my life trapped inside windows
[15:21:15] <t12> wait till you spend the next 10 years trying to get random source builds to work
[15:25:37] <Beginner_Gabe> lol i don't have that long left, im going to die at 27 like a rockstar
[15:25:50] <Beginner_Gabe> only of natural cases :)
[15:25:55] <Beginner_Gabe> causes*
[15:45:33] <r00t4rd3d> you still need windows for decent cnc work
[15:45:45] <r00t4rd3d> the design aspect of it atleast
[15:46:40] <r00t4rd3d> linux cad/cam programs compared to windows cad/cam programs dont even compare
[15:50:45] <Beginner_Gabe> freecad has came along way, its only missing assembly features
[15:51:29] <mk0> librecad needs at least ubuntu 11 :(
[16:25:08] <tjb1> Hello gents
[16:26:28] <tjb1> r00t4rd3d: I do believe I have spotted some burl wood from my treestand
[16:26:33] <skunkworks__> alex_joni: Hey - sorry I missed you. (bathroom remodel)
[16:27:27] <r00t4rd3d> its all over, the tree type and size of it and how it looks when you cut it open really matter
[16:27:42] <r00t4rd3d> some can be rotten
[16:28:16] <r00t4rd3d> have no core or just look like ass
[16:30:45] <tjb1> Beech tree
[16:31:02] <tjb1> Couple softballs in size
[16:31:20] <DJ9DJ> gn8
[16:31:30] <r00t4rd3d> yeah, they might be nice.
[16:32:01] <alex_joni> skunkworks__: np
[16:32:07] <alex_joni> I wasn't really around either
[16:32:38] <skunkworks__> heh
[16:33:18] <tjb1> Have to bring a saw down here tomorrow maybe
[16:33:32] <r00t4rd3d> do it, then send them to me :D
[16:34:23] <r00t4rd3d> if they look good, knock the bark off with a hammer and soak them in linseed oil
[16:34:40] <tjb1> Maybe I am gonna make a bowl!
[16:35:04] <r00t4rd3d> do you have a lathe?
[16:35:36] <tjb1> Who needs a lathe
[16:35:45] <r00t4rd3d> i use my drill press :)
[16:36:11] <tjb1> Use my table :)
[16:36:58] <r00t4rd3d> they a pain to mount to cut
[16:37:03] <r00t4rd3d> small ones
[16:37:21] <r00t4rd3d> i just dremel them out by hand
[16:38:06] <tjb1> Im probably gonna whack the tree down
[16:38:26] <tjb1> It requires life ending surgery
[16:43:54] <tjb1> Not a deer here...
[17:05:20] <r00t4rd3d> http://www.liveleak.com/view?i=97a_1348936594
[17:05:21] <r00t4rd3d> lol
[17:09:37] <r00t4rd3d> http://www.liveleak.com/view?i=430_1348880109
[17:09:39] <r00t4rd3d> i want one
[17:09:51] <r00t4rd3d> i wanna swim like a dolphin
[17:14:59] <andypugh> be better without the hose.
[17:15:21] <andypugh> Though rather difficult.
[17:16:24] <andypugh> I guess the main danger is landing on your jetski.
[18:10:49] <alex_joni> http://www.speedtest.net/result/2210967089.png
[18:13:02] <andypugh> That's pretty impressive.
[18:14:02] <Jymmm\AE> Hi alex_joni
[18:27:07] <Jymmm\AE> andypugh: On that 12V intel mobo, do you know how many watts it's pulling?
[18:27:24] <andypugh> No.
[18:27:28] <Jymmm\AE> andypugh: actual, not spec'ed
[18:27:35] <andypugh> Even more No
[18:27:39] <Jymmm\AE> heh
[18:28:18] <Jymmm\AE> andypugh: you don't have a peak reading watt/amp meter by chance do you?
[18:28:37] <Jymmm\AE> (hint hint nudge nudge, but no rush or anything)
[18:28:38] <andypugh> No, sorry.
[18:29:38] <Jymmm\AE> andypugh: how's it been? any issues? lagging?
[18:29:40] <andypugh> I could, in theory, insert an ammeter, but that would stop the machine.
[18:30:25] <andypugh> It sits on top of some books in the book-case and runs headless. It's hard to say how it works as a PC.
[18:30:26] <Jymmm\AE> andypugh: oh no, I meant like a clamp on or some such thing, no rush or anything few weeks would be fine.
[18:30:45] <Jymmm\AE> andypugh: what do you have it doing?
[18:31:02] <andypugh> I use it to compile and test LinuxCNC
[18:31:25] <andypugh> It has a 6i25 / 7i76 / 7i73 mounted at the moment.
[18:31:36] <Jymmm\AE> ah, does it do a good job of that, or just another box?
[18:31:47] <andypugh> Seems perectly fine.
[18:31:54] <Jymmm\AE> ok
[18:33:24] <Jymmm\AE> I want to make a low power system, and see if I can use it's LDVS connector with an old LCD I have from a dead laptop.
[18:37:20] <andypugh> The LVDS port is not the same as the one on the LVDS touchscreen I have, so you might need to have a carefull look at the connectors.
[18:38:31] <Jymmm\AE> Oh lovely, I was hoping the rumors I heard about it weren't true - some intel funkiness about it not being "standard".
[18:39:06] <Jymmm\AE> ...both the connector and the protocol.
[18:39:24] <andypugh> It's entirely possible that there is no standard. Or that my monitors (from a POS device) is non-standard
[18:39:48] <Jymmm\AE> I understand, thanks for the heads up.
[18:53:55] <r00t4rd3d> whats AE?
[18:56:59] <Jymmm\AE> r00t4rd3d: I passed my EXTRA ham license this morning, the \AE is the suffix you use till the FCC database catches up to the paperwork.
[19:14:17] <r00t4rd3d> http://i.imgur.com/t4GuQ.jpg
[19:14:32] <r00t4rd3d> air deflector for my router
[19:15:08] <andypugh> What does it do?
[19:15:16] <r00t4rd3d> deflects air
[19:15:21] <r00t4rd3d> :D
[19:15:27] <andypugh> OK, How does it do.
[19:15:42] <r00t4rd3d> makes the air blow out the sides instead of down
[19:16:01] <r00t4rd3d> blowing saw dust all over
[19:16:18] <r00t4rd3d> attaches to the bottom of my router
[19:16:23] <andypugh> So, the shape is to suit the vents on a particular model?
[19:16:30] <r00t4rd3d> yeah
[19:16:49] <andypugh> And the teardrops?
[19:17:20] <r00t4rd3d> led lights
[19:17:34] <r00t4rd3d> my router has 2 leds in the bottom
[19:19:26] <r00t4rd3d> my last attempt at shopvacless cnc machine
[19:30:53] <andypugh> Some sort of cyclonic extractor would be good.
[19:31:15] <andypugh> Might be quieter too.
[20:31:59] <ReadError> fark
[20:32:05] <ReadError> i need some like, fractional drillbits
[20:32:09] <ReadError> something in between sizes
[20:32:18] <jdh> letters?
[20:32:45] <andypugh> Adjustable reamers?
[20:33:19] <ReadError> well see the set i have
[20:33:22] <ReadError> the jump is so big
[20:33:27] <ReadError> im trying to drill out these plastic props
[20:33:34] <ReadError> and when i go to the larger size it grabs
[20:33:41] <ReadError> so its very hard to get a nice even hole
[20:33:51] <ReadError> if i step up in small increments its not an issue
[20:34:10] <andypugh> http://www.auto-ware.com/techref/drillsizes.htm
[20:34:50] <andypugh> ReadError: But it would be better to use a drill press and proper workholding.
[20:35:06] <ReadError> i cant really
[20:35:12] <ReadError> my drillpress doesnt run "true"
[20:35:15] <ReadError> too much wobble
[20:35:28] <ReadError> plus its near impossible to put them in a vice
[20:35:31] <andypugh> You could try going direct to the required size, but with a detuned drill bit.
[20:35:33] <ReadError> due to the shape
[20:36:07] <andypugh> Could you hold them in a 4-jaw chuck?
[20:37:06] <andypugh> Anyway, if you adjust the cutting edges of the drill to have slight negative rake then it won't crab.
[20:37:25] <toastyde1th> boring head
[20:37:43] <toastyde1th> shit doesn't have to run true to cut a decent hole
[20:38:09] <toastyde1th> drills bitch about runout a lot more than boring heads
[20:38:57] <toastyde1th> if you can get one that's either a square insert or circular insert it will care even less about feed
[20:39:02] <toastyde1th> stay away from triangular
[20:41:40] <ReadError> i have better luck drilling holes straight with a hand drill
[20:41:48] <ReadError> and stepping up the size slowly
[20:41:57] <ReadError> unless i need to drill 2 holes in a piece of tubing
[20:42:00] <ReadError> then i go with the press
[20:42:23] <andypugh> I find that too-small increments are more likely to grab. Strangely.
[20:43:36] <ReadError> this is plastic
[20:43:39] <ReadError> softish stuff
[20:45:11] <andypugh> Even more so.
[20:56:57] <r00t4rd3d> i could drill a prop hole with a cordless
[20:57:15] <ReadError> thats what i was using
[20:57:18] <ReadError> but the bits too big
[20:57:21] <ReadError> so it bites
[20:57:43] <andypugh> Run it in reverse and melt your way through :-)
[20:58:32] <r00t4rd3d> are you printing the props?
[20:58:46] <ReadError> hell nah
[20:58:53] <ReadError> i dont trust printed stuff
[20:59:07] <r00t4rd3d> buying them?
[20:59:11] <ReadError> yea
[20:59:13] <BHSPiMonkey> anyone here worked with shapeoko?
[20:59:27] <r00t4rd3d> no but i get emails about them weekly
[20:59:39] <BHSPiMonkey> what kind of emails?
[20:59:59] <r00t4rd3d> i think from when they were on instructables
[21:00:32] <BHSPiMonkey> any chance you're thinking of inventables (the site that sells the kits?)
[21:00:44] <r00t4rd3d> probably
[21:00:51] <BHSPiMonkey> too many -ables
[21:01:09] * BHSPiMonkey registers impeccables.com and improbables.com
[21:01:14] <r00t4rd3d> yeah i didnt mean instructables
[21:02:10] <r00t4rd3d> https://www.inventables.com/technologies/cnc-mill-kits-shapeoko
[21:02:37] <r00t4rd3d> the price has gone up
[21:02:40] <r00t4rd3d> 25 bucks
[21:02:48] <r00t4rd3d> 26 actually , was 199
[21:04:44] <tjb1> so electronics are $375...
[21:04:48] <tjb1> bullshit.
[21:05:12] <andypugh> OK, how do I find the value of the integer part of a large double?
[21:06:00] <andypugh> (using C, and only the functions in rtapi_math.h)
[21:06:15] <r00t4rd3d> BHSPiMonkey, you arent gonna buy one are you?
[21:06:15] <pcw_home> trunc?
[21:06:33] <BHSPiMonkey> r00t4rd3d: already did
[21:06:49] <r00t4rd3d> the whole kit?
[21:06:54] <BHSPiMonkey> no, mechanical only
[21:06:57] <r00t4rd3d> o
[21:07:03] <BHSPiMonkey> I'm currently sourcing the electronics
[21:07:08] <ReadError> i like the idea of the rack and pinion that tjb1 is using
[21:07:15] <r00t4rd3d> i wouldnt use an arduino
[21:07:27] <BHSPiMonkey> r00t4rd3d: I ordered an Azteeg G1 instead of an arduino+shield
[21:07:28] <andypugh> pcw_home: Ah, yes, now you mention it I do have round/floor/ceil available.
[21:09:51] <BHSPiMonkey> r00t4rd3d: trying to decide if 200-step motors are okay or if I should keep trying to hunt down 400-step ones
[21:09:54] <BHSPiMonkey> (sparkfun ran out)
[21:10:36] <r00t4rd3d> lol
[21:10:46] <r00t4rd3d> i got my steppers from there
[21:10:55] <andypugh> BHSPiMonkey: Just use 200 step ones with microstepping
[21:10:58] <r00t4rd3d> they normally restock quickly
[21:12:31] <r00t4rd3d> BHSPiMonkey, you gonna use a dremel ?
[21:13:19] <BHSPiMonkey> r00t4rd3d: my buddy has one I'm going to use in the very very beginning, but I don't know what I'm going to do beyond that
[21:13:31] <BHSPiMonkey> I am brand-spanking new to this art
[21:13:49] <BHSPiMonkey> for instance, I don't even know what andypugh means about microstepping
[21:14:41] <andypugh> BHSPiMonkey: Most stepper drives don't move in full steps. Some offer as many as 256 microsteps between each full step.
[21:15:27] <andypugh> I am not going to get into arguments about whether that achieves anything. But 4x microsteppping is perfectly good. So you get 800 positions per rev.
[21:18:00] <r00t4rd3d> BHSPiMonkey, your control board manual should tell you how to set the microstep settings
[21:19:03] <BHSPiMonkey> andypugh: hrm. Then what's the real (or philosophical) difference between a 200 and a 400 model?
[21:19:53] <andypugh> Well, with a 400 step motor and 4x microstepping you get 1600 positions per rev
[21:20:30] <andypugh> But, to be honest, I think that the 400 step motors are just trying to sell on numbers to the naive.
[21:21:29] <r00t4rd3d> more steps = more detail i think
[21:24:49] <pcw_home> I suspect they are uncommon because the magnetic compromises
[21:24:51] <pcw_home> in a100 pole motor are such that a good 50 pole motor will outperform them
[21:24:52] <pcw_home> (but it sounds cool)
[21:26:05] <r00t4rd3d> BHSPiMonkey, dont feel alone, I have a working cnc machine and have no clue what these guys are talking about most times either.
[21:26:23] <BHSPiMonkey> heh
[21:26:25] <pcw_home> 200 step = 50 pole motor
[21:27:00] <BHSPiMonkey> well a 400-step motor should be twice as precise in theory
[21:27:13] <BHSPiMonkey> but what I'm wondering is if it's worth it
[21:27:23] <r00t4rd3d> not for that little machine
[21:27:46] <BHSPiMonkey> a full revolution produces what kind of motion along one of these little belts? a half a centimeter?
[21:27:50] <r00t4rd3d> unless you want to do pcb's
[21:28:21] <BHSPiMonkey> divide that by 200, would I really care about having more detail than that?
[21:29:44] <r00t4rd3d> when you enter all your details in stepconf , like motor steps, screw pitch, etc it will figure that out.
[21:30:35] <pcw_home> normally you would not do less than 1/4 stepping anyway so that 800 steps/rev
[21:30:37] <r00t4rd3d> if you are going to use LinuxCNC with that controller you have
[21:31:36] <BHSPiMonkey> on the other hand, I might feel better knowing that I held out and got the "better" motors :P
[21:32:12] <BHSPiMonkey> the placebo effect itself could be valuable
[21:32:18] <andypugh> Check the torque/speed graphs. I wouldn't be surprised to find that the 400 step motors are both weaker and slower.
[21:32:34] <pcw_home> I dont think 400 step motors are better (they lose a lot of torque to flux leakage)
[21:32:51] <andypugh> For peak performance you use servos, which have only 4 steps per rev, but huge microstepping...
[21:33:31] <pcw_home> (pole to pole distance vs rotor stator gap gets worse on 400 step motors)
[21:36:44] <pcw_home> Also with a given drive voltage and RPM you have twice the required drive frequency so torque will drop off much faster.
[21:37:35] <r00t4rd3d> i can only get my machine to do 12ipm :/
[21:37:52] <r00t4rd3d> lovely tb6560
[21:38:07] <BHSPiMonkey> I've so much to learn
[21:38:42] <andypugh> r00t4rd3d: Your machine can't keep up with the seconds hand of a clock?
[21:38:58] <r00t4rd3d> i probably dont have my settings right either
[21:39:14] <andypugh> r00t4rd3d: More Volts!
[21:39:54] <andypugh> BHSPiMonkey: Don't worry. We all have a lot to learn too. But the things we know and you don't, we are happy to share.
[21:40:11] <r00t4rd3d> i have a 24v supply
[21:40:24] <andypugh> Ah.
[21:40:37] <BHSPiMonkey> yay
[21:54:16] <andypugh> https://picasaweb.google.com/lh/photo/aAihldBxgUVCTCc2hTl4O9MTjNZETYmyPJy0liipFm0?feat=directlink
[21:54:50] <andypugh> Nearly there
[21:54:53] <BHSPiMonkey> fuuun
[21:56:03] <pcw_home> Wow you got the formatting working Thats neat (though thats a hard to read display)
[21:56:43] <andypugh> I can't seem to get any more contrast either
[21:57:02] <andypugh> I will get a meter on the pin tomorrw.
[21:57:08] <andypugh> (err, today)
[21:57:49] <tjb1> what you running that display with andypugh
[21:58:05] <pcw_home> The one we used is white on blue with really good contrast
[21:58:07] <pcw_home> (but contrast controls vary so the 7I73 method may not work with all displays)
[21:58:26] <andypugh> pcw_home: If it changes Vee, then it should work
[21:58:48] <andypugh> tjb1: Mesa 7i73 and a new HAL comp.
[21:59:07] <tjb1> I got this one andypugh but it doesnt have enough lines for you… -
http://www.amazon.com/Character-Module-16x2-Backlight-Arduino/dp/B004MGPALC/ref=sr_1_4?ie=UTF8&qid=1348973191&sr=8-4&keywords=16x2+display
[21:59:16] <tjb1> Any color in the rainbow :)
[21:59:25] <andypugh> The magic is in this HAL line" loadrt lcd fmt_strings="LinuxCNC - Tool %2i\nX Pos = %4.3f\nY Pos = %4.3fi\nZ Pos = %4.4f
[21:59:57] <andypugh> (and I am relived to see that the spurious "i" is in the format string, not in my code :-)
[22:00:16] <tjb1> looks like some stuff I have done in java...
[22:01:05] <andypugh> You pass a printf-style string to the component, it then creates HAL pins according to the format specifiers, adn then the display shows the HAL pin values.
[22:01:07] <pcw_home> its one of those new fangked iNumbers
[22:01:24] <pcw_home> Thats really nice
[22:01:47] <andypugh> tjb1: It would run your LCD pefectly happily, if you had a 7i73.
[22:02:12] <pcw_home> is it using the quad char mode?
[22:02:23] <tjb1> Ill probably use mine with my arduino torch height control
[22:02:27] <andypugh> pcw_home: Now I have it working, I like it too. But I still have no real idea what folk want LCD panels for.
[22:02:46] <pcw_home> Mainly pendants
[22:02:51] <andypugh> pcw_home: No, single char. Quad char is actually something of a pain.
[22:03:22] <andypugh> It could be done, but I am not sure it is worth the trouble.
[22:03:29] <pcw_home> not as natural as byte streams
[22:03:40] <pcw_home> only advantage is faster update rate
[22:03:51] <andypugh> 10Hz updates seems plenty fast enough for my reaction time
[22:04:14] <pcw_home> the LCD is not terribly fast either
[22:05:27] <pcw_home> updated at 1KHz servo thread its about like 9600 baud
[22:06:36] <tjb1> goodnight gents
[22:07:56] <pcw_home> Thats great work Andy! You beat the formatting problem into submission!
[22:08:09] <jp_> hmm how could i use the 7i73 with a 5i25?
[22:08:12] <andypugh> Well, some of it.
[22:08:28] <BHSPiMonkey> can linuxcnc run on an r-pi?
[22:08:41] <BHSPiMonkey> not that I need it to, but I do have one and I am curious
[22:09:01] <pcw_home> jp_ you need a 422 interface of some kind
[22:09:13] <andypugh> pcw: I'll email you a copy, it ought to compile and install with comp.
[22:09:16] <pcw_home> maybe just a single chip (SP491)
[22:09:19] <jp_> can i use the 7i76 with it
[22:09:42] <pcw_home> yes it works directly with 7I76
[22:09:44] <andypugh> 7i73 plugs stright into the 7u76
[22:09:55] <andypugh> That's exactly my setup
[22:10:14] <jp_> it does or make a cable for it
[22:10:27] <andypugh> BHSPiMonkey: A bit. Not 100% yet, but there are Pi's with LinuxCNC installed
[22:10:29] <pcw_home> you need a funky serial cable but instructions are in the 7I76 manual
[22:11:06] <andypugh> (It's a network cable with the end pulled off and connected to a terminal block)
[22:11:07] <pcw_home> (or we can sell you one with classy ferrules on the wires)
[22:11:07] <jp_> guess i should get playing with mine then
[22:11:26] <jp_> nah gots my own ferrules
[22:11:42] <pcw_home> I love those things
[22:11:54] <jp_> thats the only way to wire
[22:12:43] <pcw_home> after fighting broken wires on test jigs they have really been a blessing
[22:13:06] <andypugh> I have lots of ferrules all over my machines
[22:13:12] <jp_> tension clamp TB's are a fav of mine as well
[22:13:36] <andypugh> Can you use both? I guess only if you have a ferrule crimper
[22:14:20] <andypugh> But I guess you are not really meant to use the terminal blocks to crimp the ferrules anyway
[22:14:26] <jp_> use both?
[22:14:31] <jp_> no
[22:14:48] <pcw_home> Yes they provide a nice strain relief for the wire (crimper was on $59.00 or some such)
[22:15:00] <pcw_home> s/on/only/
[22:15:28] <jp_> wiedmuller every now and then puts a full kit on sale for a nice price
[22:15:47] <BHSPiMonkey> I've noticed a lot of CNC videos show a lot of mess particles getting thrown all over the place; Any common practices for keeping that contained?
[22:16:05] <BHSPiMonkey> Do many people throw up enclosures?
[22:16:13] <toastyde1th> enclosures are the #1 way
[22:16:29] <toastyde1th> on smaller mills you can put plastic shields on magnets or flex arms
[22:16:30] <andypugh> The big commercial machines are fully-enclosed and have conveyors in the bottom to take away the swarf
[22:16:54] <BHSPiMonkey> I'm picturing just using a shower curtain creatively
[22:17:05] <andypugh> Or learn to enjoy hot metal embedding itself in your collar bone.
[22:17:05] <toastyde1th> those work too
[22:17:36] <BHSPiMonkey> andypugh: do chicks dig that nowadays?
[22:18:03] <andypugh> If you care what chicks dig you might have taken up the wrong hobby :-)
[22:18:26] * BHSPiMonkey converts foreveralone.jpg to gcode
[22:38:39] <andypugh> Aha! JT-Shop I figured out how to mass-delete the spammers. Show 500, click the "select all button" then unselect one. Then it enables the delete button, and you can delete the unselected one later.
[22:39:07] <andypugh> I am just glad they haven't figured out how to use real names.
[22:39:25] <andypugh> (I also have no idea how they expaect to make profit from it, even if they did get in)
[23:50:54] <tjb1> Im excited to have a 3d printer
