[03:58:32] <MattyMatt> random ebay "wish I had a truck" moment http://www.ebay.co.uk/itm/ANCA-FASTGRIND-TG4-CNC-CUTTER-GRINDER-grinding-machine-4-axis-No-Reserve-/291133164724
[04:03:47] <Valen> MattyMatt: damn
[04:11:58] <MattyMatt> I could save tens of pounds in tooling with that >:)
[07:15:39] <jthornton> Tom_itx, you getting any of this rain?
[07:18:47] <Tom_itx> we got a little the other morning but nothing much
[07:19:55] <Tom_itx> went to a civil war reenactment saturday... must say the cannons were pretty cool
[07:20:20] <Tom_itx> took a few pics but i'm sure you know what cannons look like
[07:21:45] <Tom_itx> looks like the weather is just touching the corner of Mo
[07:22:03] <MattyMatt> https://www.youtube.com/watch?v=kcSMaNlcDPs
[07:24:36] <jthornton> yea
[07:25:17] <jthornton> did they shoot the cannons?
[07:25:22] <Tom_itx> yup
[07:25:29] <Tom_itx> 3 different ones
[07:25:44] <Tom_itx> long barrel and 2 short
[07:26:41] <jthornton> short like a mortar?
[07:26:49] <Tom_itx> no
[07:27:01] <Tom_itx> probably 3' or so
[07:28:11] <Tom_itx> brb...
[07:34:07] <Tom_itx> jthornton, http://tom-itx.dyndns.org:81/~webpage/temp/misc/cannonfire.jpg
[07:38:05] <Tom_itx> the long barrel: http://tom-itx.dyndns.org:81/~webpage/temp/misc/cannon.jpg
[07:42:24] <Tom_itx> and the confederate one: http://tom-itx.dyndns.org:81/~webpage/temp/misc/cannon_confed.jpg
[07:42:29] <Tom_itx> it was by far the loudest
[07:45:30] <jthornton> the long barrel looks like a 6 pounder and the other two look like mountain howitzers
[07:46:02] <jthornton> the 6 pounder might be 3/4 scale
[07:46:26] <jthornton> the other two look like 1/2 scale
[07:46:47] <Tom_itx> gotta run...
[07:46:55] <jthornton> k
[08:17:30] <_methods> haha if you want your little kid to turn out to be a bitch don't feed him food on the bone
[08:17:33] <_methods> http://www.sciencedirect.com/science/article/pii/S1471015314000397
[08:18:04] <_methods> kids that chew food are 2x as aggresive as little bitches that suck milk from mamma's tittay
[08:18:14] <_methods> who'da thunkit
[08:18:33] <jdh> I'd say taht also carries over through adulthood
[08:18:58] <_methods> that's why i eat live chickens
[08:20:49] <XXCoder> http://www.smbc-comics.com/?id=3337#comic ;)
[09:11:59] <pcw_home> gonzo_: try freeby.mesanet.com/mesaflash
[09:12:01] <pcw_home> I think the mesaflash binary in th e7I90 zipfile is too old for EPP support
[09:12:02] <pcw_home> (the mesaflash3 binary will work but only under 12.04)
[09:36:29] <gonzo_> pcw_home, thanks peter, will try that later
[09:39:10] <pcw_home> I think micges/cradek have packaging of mesaflash working
[09:43:20] <cradek> yes - we should get it into the git.linuxcnc.org repository as soon as you guys are ready
[10:19:48] <JesusAlos> hi
[10:22:16] <JesusAlos> I'm testing gmoccapy graphical environment
[10:22:25] <JesusAlos> any body use it?
[10:23:13] <JesusAlos> I don't see the option 'run from here' in contextual menu in gcode window
[11:06:38] <Jymmm> archivist: new scam… https://www.youtube.com/embed/-K-zDK4wrI4?rel=0&showinfo=0&autoplay=1&vq=large
[11:09:37] <_methods> hehe
[11:28:29] <Jymmm> _methods: =)
[12:01:55] <zeeshan> so im calculating the feed force required for a worst case scenario. one of the most energy consuming materials is 4340. power constant of 1.31 hp/(in^3/min) and hardness of 485 HB. using a maximum depth of cut of .125" and the recommended feedrate for a .002 ipr, im finding out my feed force is approximately 70lb
[12:02:14] <zeeshan> that means my bracket that attaches to the apron and the ball nut
[12:02:18] <zeeshan> will see this force
[12:02:30] <zeeshan> meaning it'll deflect 0.0008" at those parameters
[12:03:27] <zeeshan> since the bracket deflects by that much, wouldn't this show up as 'backlash'
[12:03:46] <zeeshan> but its a consistent back lash
[12:05:51] <MrHindsight> how do you know it will deflect by 0.008"?
[12:06:05] <zeeshan> FEA verified with hand calculations
[12:06:28] <pcw_home> strain gauge --> LPF --> offset commanded position
[12:06:41] <zeeshan> pcw_home: would love to do that
[12:06:42] <MrHindsight> and how about when measured? vs simulated/calculated
[12:06:54] <zeeshan> MrHindsight: i did a cutting forces lab a while ago
[12:07:09] <zeeshan> i don't personally have a load cell
[12:07:11] <MrHindsight> great, have you measured it yet?
[12:07:21] <zeeshan> but the formula was within +/-8%
[12:07:25] <zeeshan> so it's accurate enough
[12:07:43] <pcw_home> Samco did that with spindle temperature comp
[12:07:53] <zeeshan> i'm wondering if that 0.0008" would show up as back lash or not
[12:07:53] <MrHindsight> you keep on assuming something that I am not
[12:07:54] <zeeshan> i mean
[12:09:50] <MrHindsight> maybe, maybe not. We simulate all the time as a ballpark then actually measure.
[12:10:17] <zeeshan> for example i'm confused about this. imagine a 2" diameter x 6" piece, i'm cutting 4340, at a depth of cut of 0.125" and 0.002 ipr, which requires feed force 70lb, length of cut is 2.0000" one pass. ---- this is a roughing pass.
[12:10:24] <zeeshan> if i command 2.000 to be cut
[12:10:39] <zeeshan> in reality it would only cut 1.9992 due to the deflection right?
[12:10:50] <zeeshan> and "flex of the lead screw bracket"
[12:11:04] <IchGuckLive> hi all
[12:11:07] <IchGuckLive> B)
[12:11:21] <MrHindsight> possibly or somewhere in between or as a pattern near those limits
[12:11:32] <zeeshan> now lets say i go back to home
[12:11:34] <zeeshan> and do a second pass..
[12:11:49] <zeeshan> and command 2.0000" (finishing pass) which only requires 10 lb of force
[12:11:58] <zeeshan> and deflects only by 0.0001"
[12:12:19] <zeeshan> would it actually make the piece 1.9999"?
[12:12:34] <zeeshan> or would it be some weird number
[12:12:40] <zeeshan> because of the way the screw is flexing
[12:12:41] <MrHindsight> it might oscillate and vary by the type of and number of cutting faces
[12:12:59] <zeeshan> but the error will always be consistent through right?
[12:13:02] <zeeshan> within a specific range
[12:13:08] <zeeshan> it won't stack up right?
[12:13:14] <MrHindsight> it's probably not constant either, like a boat going over waves
[12:13:19] <zeeshan> ofcourse
[12:13:28] <zeeshan> this is to get a rough idea of what kind of error it is
[12:13:32] <zeeshan> i'm confused if it causes a stack up error
[12:13:49] <zeeshan> or an error within the rigidity bound of the bracket
[12:14:08] <MrHindsight> heh, welcome to modeling dynamic systems
[12:14:30] <zeeshan> MrHindsight: i'm not trying to get the exact numbers
[12:14:37] <zeeshan> i'm just trying to figur eout the type of error :P
[12:15:34] <MrHindsight> if cutting depth changes the amount of force on the screw and bracket then it will probably bend less
[12:16:23] <MrHindsight> so in the one situation you might have 0.0008" and in the other 0.0001" deflection sure
[12:16:42] <MrHindsight> and if you change speeds some other amount of deflection for both
[12:16:59] <zeeshan> yes
[12:17:25] <zeeshan> so basically to hit my exact target
[12:17:33] <zeeshan> i need to just lower the cutting forces during the finishing pass
[12:17:47] <zeeshan> and i can expect to hit my target pretty close
[12:17:59] <zeeshan> (this is a stepper system)
[12:18:07] <MrHindsight> and something non-linear if you get into any resonant modes
[12:19:02] <zeeshan> resonance is a whole different ball game :P
[12:19:13] <zeeshan> cutting forces oscillate like crazy.
[12:19:14] <zeeshan> :P
[12:19:18] <zeeshan> especially the tangential one
[12:19:28] <zeeshan> the formula i have assumes no resonance
[12:19:59] <zeeshan> if you start included resonance, you gotta solve it numerically cause its a long ass differential equation
[12:20:07] <zeeshan> based on the system
[12:20:13] <MrHindsight> lots of people like to start some exact expected number as a result, I usually approach it from chaos and try to limit or control all the variables
[12:20:35] <zeeshan> well cause i've never designed a bracket for this scenario before
[12:20:39] <zeeshan> so i need to get in the ball park :P
[12:20:56] <zeeshan> i need to know if 70lb will give me 10 thou of deflection of 1 thou or tenths
[12:21:19] <MrHindsight> things are always moving, twisting, changing temp, getting contaminated, oxidizing etc etc
[12:21:23] <zeeshan> ofcourse with resonace your typical 1 thou deflection can peak 10 thou
[12:21:28] <zeeshan> but you'd know something is really wrong!
[12:22:44] <zeeshan> http://i.imgur.com/s33bP02.png
[12:22:47] <zeeshan> this is what the bracket looks like
[12:23:02] <zeeshan> to me it looks over kill
[12:23:08] <zeeshan> but according to simulations its not
[12:23:11] <MrHindsight> in a static situation wouldn't you get the 0.0008" deflection based on a 2" diameter x 6" piece, i'm cutting 4340, at a depth of cut of 0.125" and 0.002 ipr, which requires feed force 70lb, length of cut is 2.0000" one pass
[12:23:55] <zeeshan> you'd prolly get less i'd presume
[12:23:59] <MrHindsight> that force is based on the size and depth of cut
[12:24:46] <MrHindsight> are you questioning your formula or?
[12:24:58] <zeeshan> it just looks overly big to me.
[12:25:05] <zeeshan> but i've never really designed for 0.0001 " deflections before
[12:25:08] <MrHindsight> I'm not exactly sure since from my perspective you answered your own question
[12:25:12] <zeeshan> mostly i've designed for strength
[12:25:25] <zeeshan> MrHindsight: no you've helped me confirm some things.
[12:25:30] <zeeshan> cause i was kind of lost
[12:25:41] <zeeshan> as to what kind of error it'd cause
[12:25:58] <zeeshan> i was thinking it'd cause a stack up error like when you stack up 10 different gage blocks together
[12:26:37] <MrHindsight> and then you'll next have to consider the CTE of the materials if you're concerned about 0.0001"
[12:26:51] <zeeshan> MrHindsight: i'm overdesigning it for worst case scenario
[12:27:08] <zeeshan> like when i got 70lb of max force using the formula
[12:27:14] <zeeshan> i actually applied 120lb of force on the bracket
[12:27:25] <zeeshan> and its deflection 0.0007-.0008
[12:27:49] <MrHindsight> heh, in the olden days they would have used 4x the max expected load
[12:27:55] <zeeshan> haha
[12:27:58] <zeeshan> it's my hobby machine!
[12:28:02] <MrHindsight> so the machine would still be in spec 50 years later
[12:28:34] <MrHindsight> now they would use maybe 1.1 - 1.5x and cross their fingers
[12:28:49] <MrHindsight> and hope they don't get calls before the warranty is up
[12:28:55] <zeeshan> only when it comes to non important things
[12:29:03] <zeeshan> i know at my last company when we made enclosures
[12:29:10] <zeeshan> factor of safety of 3 was typical
[12:29:22] <zeeshan> and 8 or 10 for lifting applications
[12:29:36] <zeeshan> such as lifting brackets for 1000lb enclosures
[12:30:08] <zeeshan> don't want death on my hands!
[12:32:05] <archivist> try for resonant deflections :)
[12:45:12] <MrHindsight> zeeshan: isn't a simple model just a lever with the bracket as the fulcrum?
[12:46:31] <MrHindsight> or use the end of the tool as the fulcrum
[12:57:34] <archivist> so you do your strength and bending calcs, happy bunny, then a bit of wind blows, https://www.youtube.com/watch?v=j-zczJXSxnw
[12:58:45] <zeeshan> hahah
[12:58:49] <zeeshan> dynamic is important
[12:58:50] <zeeshan> :D
[12:59:00] <zeeshan> ive never seen the color version of gallpoin
[12:59:01] <zeeshan> nice
[13:02:40] <archivist> good slomo of it
[13:03:58] <archivist> a recent bridge in the UK was set off by the people walking across
[13:07:09] <archivist> hehe kids https://www.youtube.com/watch?v=uWoiMMLIvco
[13:12:22] <MrHindsight> in the US we're starting to see how well bridges were made in the 40's-80's since they are no longer maintained
[13:15:57] <archivist> the british cock up bridge https://www.youtube.com/watch?v=gQK21572oSU
[13:34:52] <Jymmm> _methods: Hey, thanks for that ebay link! Got the carboy wrench today, works perfectly!!!
[13:35:47] <_methods> np man
[13:35:50] <_methods> awesome
[13:36:06] <_methods> i'm an ebay whore
[13:36:16] <_methods> always love to hone the search skillz
[13:36:19] <Jymmm> _methods: Works for me =)
[13:36:58] <_methods> i owe ya for gettin that shaun clown out of here i guess lol
[13:37:09] <_methods> assuming that was you heheh
[13:37:32] <Jymmm> Eh, he might be back, so dont thank me too quickly, youmight be cussing me out soon enough =)
[13:37:42] <_methods> heheh
[13:40:36] <Jymmm> and of course your favorite _methods...
[13:40:40] <_methods> ah man
[13:41:13] <MrHindsight> can i bring back my old library books today as well without getting charged for late fees?
[13:41:44] <Jymmm> MrHindsight: Amnesty day?
[13:42:08] * archivist collects late fees
[13:42:09] <malcom2073> _methods: You don't mean shaun413 do ya?
[13:42:16] <_methods> shhhh
[13:42:18] <_methods> don't say his name
[13:42:26] <malcom2073> Lol
[13:42:29] <malcom2073> Was he asking about lathes? :P
[13:42:34] <_methods> oh god
[13:42:38] <Gigs-> it's metal "shear" right? I keep seeing people write "sheer" for the tool that cuts metal.
[13:42:41] <malcom2073> We've dealt with him before lol
[13:42:45] <Jymmm> malcom2073: where?
[13:42:49] <malcom2073> in #reprap
[13:43:03] <Jymmm> sigh
[13:43:36] <malcom2073> He's been asking about what lathe to get for... about the last month
[13:43:49] <Jymmm> YEah, we know
[13:43:55] <ReadError> lol
[13:44:00] <malcom2073> It took him 6 months in the reprap video chat, to get a working 3d printer... build tt from a kit
[13:44:03] <humble_sea_bass> sigh
[13:44:07] <malcom2073> with lots of help from a great many people
[13:44:13] <humble_sea_bass> #emacs -- not even once
[13:45:03] <_methods> yeah if you can't make a 3d printer you should probably go back to the custodial engineering shop you came from
[13:45:38] <malcom2073> Heh, when you can't even meet the standards of good enough for reprap.... :P
[13:45:51] <humble_sea_bass> so he had a 3d printer?
[13:45:58] <malcom2073> Two of them now
[13:46:00] <humble_sea_bass> what coulda fooled me
[13:46:24] <humble_sea_bass> that dude is flunking out of his engineering program for sure
[13:46:32] <ReadError> malcom2073, funny
[13:46:37] <ReadError> the only reason he wants a lathe
[13:46:41] <_methods> even the mention of his name drags the room iq down like 200 pts
[13:46:46] <ReadError> is to manually clone/make/sell nozzles
[13:46:50] <ReadError> lol
[13:47:00] <malcom2073> ReadError: Yeah, I know.
[13:47:16] <Jymmm> I'd just use carb jets =)
[13:47:27] <malcom2073> Oh man I'm gonna suggest that
[13:47:31] <malcom2073> he'll be in the #cars channel asking about them :P:
[13:47:31] <_methods> diesel glow plugs lol
[13:47:52] <Jymmm> malcom2073: Mention my name and I'll kill you!
[13:47:59] <malcom2073> Haha not a word :)
[13:48:31] <malcom2073> So, I was running linuxcnc off a CD yesterday to get my stuff up and running..... totally forgot to save the settings and lost it when shut down last night :/
[13:48:31] <Jymmm> malcom2073: As in murder, not somethng that someone says in hest ;)
[13:48:38] <malcom2073> Jymmm: Oh no, I understand heh
[13:48:50] <Jymmm> malcom2073: ty =)
[13:49:08] <_methods> why they all trying to get you to make them parts?
[13:49:20] <malcom2073> Who to make what huh?
[13:49:32] <_methods> Jymmm: not wanting his name spoketh
[13:50:28] <humble_sea_bass> beatlejuice beatlejuice
[13:50:56] <malcom2073> Jymmm: full disclosure, i'm a 3d printer too, but don't hate me for it.
[13:51:16] <humble_sea_bass> nothing but love here mang
[13:51:26] <_methods> yeah well at least you have linuxcnc running
[13:51:34] <Jymmm> malcom2073: I dont care about that, just dont want him in here bagging/whining about it
[13:51:35] <_methods> so you are win
[13:52:25] <Jymmm> malcom2073: When you can do glass impregated nylon, let me know
[13:52:33] <malcom2073> Lol yeah
[13:53:10] <_methods> i make some parts for a company out of glass impregnated delrin
[13:53:20] <Jymmm> malcom2073: And this detail/finish http://i.ebayimg.com/00/s/NzIwWDk2MA==/z/ReYAAMXQVERS4Y0V/$_57.JPG
[13:53:25] <_methods> stuff's kinda spiffy
[13:53:32] <malcom2073> Jymmm: You're looking on the wrong place for that kind of stuff.
[13:53:50] <Jymmm> malcom2073: ebay?
[13:53:55] <malcom2073> no, I mean 3d printing
[13:54:15] <Jymmm> malcom2073: It's a simple wrench *shrug*
[13:54:23] <malcom2073> Yeah.
[13:55:13] <Jymmm> I could EASILY add a 3D printing head to my 24"x24"x6" travel gantry router, but yeah, no thanks =)
[13:55:19] <malcom2073> Heh
[13:55:31] <malcom2073> So I'm going through configuring this again, thinking "Why the hell don't I find a hard drive to install this on" lol
[13:55:34] <malcom2073> I'm gonna wind up forgetting to save again
[13:56:34] <_methods> Jymmm: without a 3d printer how are you going to make awesome stuff like this
[13:56:39] <_methods> http://www.thingiverse.com/thing:199786
[13:57:18] <_methods> i love to go to thingiverse when i'm sad because the stuff on there makes me laugh so much
[13:57:35] <malcom2073> Yeah thingiverse is pretty uh....
[13:57:50] <malcom2073> What's a word for when non-engineers try to engineer things to be trendy? :P
[13:57:59] <Jymmm> _methods: Uh, If I was sic and twisted enough to WANT to make one, I'd thermoform it
[13:58:07] <_methods> hehe
[13:58:35] <humble_sea_bass> _methods: wtf
[13:58:38] <MrHindsight> glass nylon is not a problem, same for epoxy carbon, epoxy silica glass, urethane epoxy carbon glass silica aluminum oxide
[13:58:40] <_methods> http://www.thingiverse.com/thing:313445
[13:58:42] <_methods> oh yeah
[13:58:44] <Jymmm> _methods: Make shitloads of them and sell em tothe bastards in line for $50/each
[13:58:58] <_methods> wut's her #
[13:59:06] <_methods> or his?
[13:59:16] <humble_sea_bass> "Hello my name is http://www.thingiverse.com/thing:199786 and I am t he face of 3d printing"
[13:59:31] <MrHindsight> only if they glow in the dark
[14:00:13] <_methods> here this guy sums up 3d printing
[14:00:15] <_methods> http://www.thingiverse.com/thing:313440
[14:00:23] <_methods> god i love thingiverse
[14:00:26] <humble_sea_bass> holy christ on a 3d printed cross I think I'm having a heart attack from laughing
[14:01:51] <MrHindsight> you laugh, but just think about the mustache impaired
[14:01:54] <_methods> thingiverse is a comedy goldmine
[14:02:31] <Jymmm> Things not to do... See: thingiverse
[14:02:41] <MrHindsight> you think that's bad go visit a Makerspace
[14:02:42] <humble_sea_bass> time to take a 15 minute break before someone comes and checks on me
[14:02:48] <_methods> hahah
[14:03:36] <MrHindsight> 5-10 people probably discussed the mustache and then used 8 different applications to create the 3d model
[14:04:20] <MrHindsight> then tried 4 different slicers/cam tools to generate the G-code followed by a war over which rickety printed did it best
[14:04:33] <MrHindsight> printed/printer
[14:05:17] <_methods> that cyclops guy is part of a gang
[14:05:32] <_methods> they have printed all kinds of superzero outfits
[14:06:03] <MrHindsight> in the mean time several other thought that they could write better slicing, 3d modeling and cnc control software for use on their Rpi's
[14:06:11] <Jymmm> playdough factory comes to mind
[14:06:17] <_methods> haha
[14:06:51] <_methods> http://www.turdtwister.com/
[14:06:58] <_methods> the pinnacle of 3d printing
[14:06:58] <Jymmm> Anyone know a SAFE way to drill bakelight?
[14:07:35] <archivist> remove the rake on the drill bit
[14:08:05] <andypugh> Ye Olde Drill Sharpening poster seems to suggest an unusual point angle.
[14:08:07] <MrHindsight> diamond core bit
[14:09:44] <Jymmm> archivist Like on the right? http://www.intechopen.com/source/html/19652/media/image5.png
[14:09:48] <archivist> diamond will glog
[14:10:18] <MrHindsight> I use it wet
[14:10:28] <_methods> 80deg drill point
[14:11:03] <archivist> one on the left looks done the right looks a pigs ear of a projection
[14:11:11] <MrHindsight> http://www.fine-tools.com/kunststoffbohrer.html
[14:12:04] <Jymmm> heh
[14:12:27] <archivist> the rake removal stops the grab when you break through
[14:12:39] <Jymmm> ah
[14:12:58] <archivist> be effin careful when breaking through
[14:13:22] <_methods> interpolate it?
[14:13:23] <MrHindsight> they cleave easily
[14:13:32] <archivist> we also do that for drilling brass sheet
[14:13:33] <_methods> how many holes you gotta pop
[14:13:40] <Jymmm> I'll add a solid backer to give it extra support
[14:14:00] <Jymmm> _methods: just a few
[14:14:13] <archivist> try on some scrap first
[14:14:25] <Jymmm> archivist: thanks, will do.
[14:14:25] <_methods> well if its only a few i'd interpolate em
[14:14:53] <_methods> unless they are too deep or too small or something
[14:15:01] <_methods> then you're just screwed lol
[14:15:59] <Jymmm> _methods: Gee, thanks (bastard)
[14:17:22] <_methods> haha
[14:17:26] <andypugh> Ah, there we are. More pointy, rather than less-pointy :-)
[14:18:15] <MrHindsight> why don't the brains behind rerap work on low cost waterjets or laser cutters or something else useful?
[14:18:43] <_methods> ugh waterjets.........
[14:19:12] <archivist> MrHindsight, brains...not sure about that
[14:19:13] <_methods> noisy, dirty, always breakin down
[14:20:01] <MrHindsight> http://www.youtube.com/watch?v=1qiMELAMxes
[14:21:28] <_methods> my wife would fuckin shoot me instantly after firing that up
[14:21:43] <_methods> the mill gets me enough stink eye
[14:24:02] <zeeshan> wear your wife beater

[14:24:52] <_methods> i hate waterjets
[14:24:59] <_methods> that will never be in my garage
[14:25:03] <zeeshan> haha
[14:25:09] <zeeshan> theyre cleaner thasn plasma cutting
[14:25:18] <zeeshan> honestly, i think the best type of @ home large scale machine
[14:25:19] <zeeshan> is a laser cutter
[14:25:23] <zeeshan> its just the cutting head costs a lot.
[14:25:31] <jdh> as does the power for it.
[14:25:35] <_methods> ^^
[14:25:43] <zeeshan> :P
[14:25:46] <zeeshan> but its such a clean process!
[14:25:47] <_methods> wtf you gonna cut with a co2 laser
[14:25:51] <_methods> acrylic
[14:25:55] <_methods> plywood
[14:25:59] <zeeshan> im talking about 4000W lasers
[14:26:03] <_methods> haha
[14:26:03] <zeeshan> they can cut 1/4 steel
[14:26:06] <zeeshan> ez
[14:26:17] <zeeshan> one thing ive noticed is
[14:26:19] <zeeshan> for the hell of it
[14:26:22] <Connor> _methods: What's wrong with water jets ?
[14:26:31] <zeeshan> i injected my plasma cutter with nitrogen
[14:26:34] <_methods> their noisy, dirty, always breakin
[14:26:35] <zeeshan> and it cuts a lot nicer
[14:26:37] <_methods> blowin seals
[14:26:47] <_methods> fuckin garnet
[14:26:55] <_methods> everywhere
[14:26:56] <zeeshan> garnet is like aids in the lungs
[14:27:03] <jdh> I thought blowign seals was popular in canada
[14:27:08] <_methods> hahah
[14:27:15] <jdh> must be the newfies
[14:27:19] <zeeshan> jdh
[14:27:22] <zeeshan> did you see latest bracket?
[14:27:26] <jdh> nope.
[14:27:27] <zeeshan> im gonna go with the style you went with
[14:27:37] <MrHindsight> http://www.youtube.com/watch?v=QmKWoaRlFDc try this on your mill

[14:28:02] <zeeshan> deflects .0008" under a static load of 120lb
[14:28:34] <zeeshan> i wanted to make it out of 1/2" plate
[14:28:34] <_methods> if i ever have to do that i'll sub it out
[14:28:42] <zeeshan> but it flexes 5 thou
[14:29:02] <zeeshan> and i cant box the top piece because ill have a ball screw cover there
[14:29:04] <MrHindsight> or just buy the wavy version glass :)
[14:29:09] <_methods> we cut alot of glass like that here at my work on our jet
[14:29:14] <_methods> for streit armor
[14:29:20] <_methods> and for mraps
[14:29:39] <zeeshan> dont you get tempted to put your finger
[14:29:40] <zeeshan> in front of the jet
[14:29:43] <zeeshan> just to 'feel it'
[14:29:49] <zeeshan> by the time you feel it, you would have no finger though
[14:29:50] <zeeshan> ;[
[14:29:52] <_methods> i used to run the jet and i had to carry a card
[14:30:11] <_methods> that warned dr's i could have crazy shit in my blood stream from the waterjet
[14:30:26] <_methods> and if i came into the er i need to go on crazy antibiotics right away
[14:30:53] <_methods> that tank is like a giant toilet bowl

[14:37:55] <MrHindsight> well if you get it stuck on a really hairy part it can do some damage getting pulled off
[14:38:32] <MrHindsight> so probably should be warned about removal of excess body hair before use
[14:38:40] <MrHindsight> or experimentation
[14:40:10] <MattyMatt> that's true for all machine tools

[14:49:50] <MrHindsight> why do most at the makerfairs/spaces have such resistance to actual science and learning?
[14:50:02] <malcom2073> Because most science and teaching people won't talk to them.
[14:50:21] <MrHindsight> the ones around here are all 20 somethings that act like know it alls
[14:50:36] <malcom2073> That's because the smart decent ones get driven out.

[14:51:39] <MrHindsight> sad when there's so much idiocracy and they manage to ruin these as well
[14:53:32] <malcom2073> And on that note, time to go give this print a try with linuxcnc :)
[15:30:46] <JesusAlos> please, no body use gmoccapy interface?
[15:31:25] <malcom2073> Never heard of it, I like it though as I have a touch screen
[15:31:42] <JesusAlos> don't appear "run from here" in contextual gcode window
[15:31:57] <jdh> I've never used run-from-here
[15:31:58] <JesusAlos> don't implemented this function?
[15:32:10] <jdh> I have edited/reloaded many times
[15:32:13] <jdh> (with axis)
[15:36:46] <JT-Shop> I use touchy, I've not had the time to try gmoccapy
[16:09:36] <Deejay> gn8
[16:14:56] <JesusAlos> gn
[16:15:25] <JesusAlos> any reference about PC+touch panel embebed for linuxcnc?
[16:15:31] <JesusAlos> economical
[16:36:17] <gonzo_> pcw_home, are you around?? Have some mesaflash - 7i90 questions if you don't mind
[16:39:41] <micges> gonzo_: ask away, I'll try help
[16:40:58] <gonzo_> micges, cheers
[16:41:24] <gonzo_> trying a version of mesaflash that peter suggested, with A7i90
[16:41:44] <gonzo_> not getting comms
[16:42:15] <gonzo_> managed to program a flash image into it with the dos util (all that was avail at the time)
[16:42:30] <micges> what ubuntu version?
[16:42:33] <gonzo_> now trying mesaflash on the same pc
[16:43:09] <gonzo_> will look
[16:43:34] <andypugh> JT-Shop: I use touchy too. I am rather wishing that I could figure out a way to make CamBam put in line numbers _only_ on toolchanges.
[16:43:37] <micges> gonzo_: do you know git?
[16:44:26] <gonzo_> only as an insult
[16:44:49] <micges> heh
[16:44:51] <gonzo_> ubuntu 10.04LTS
[16:44:56] <Connor> andypugh: Why ? and you use CamBam too ?
[16:45:26] <micges> gonzo_: what do you type and what error you get?
[16:46:11] <Connor> Any way we can get gmoccapy and/or axis to support the / 2 option Like mach does when using the DRO func ?
[16:46:20] <andypugh> Connor: Touchy will only do run-from-line with lines that have numbers. So the trick is to put lines in potential restart points.
[16:46:28] <gonzo_cnc> smb://linuxsrv3/datadrive/files/mech/cnc/linuxcnc/7i90/7i90%2020140428%20mesaflash%20only/mesaflash
[16:46:34] <Connor> andypugh: Ah.
[16:46:51] <gonzo_> nope that cut and paste didn't work
[16:47:01] <Connor> and, how the heck did gmoccapy get it's name ?
[16:47:25] <andypugh> Mocca gui was a gui written in Pascal.
[16:47:43] <gonzo_> ./mesaflash --device 7I90epp --verify filename.bit
[16:47:45] <andypugh> gscreen is a gui written in Python
[16:48:06] <andypugh> Gmoccapy is a “skin” for gscreen that mimics Mocca.
[16:48:16] <micges> gonzo_: what is your lpt address?
[16:48:24] <gonzo_> result: No 7I90EPP board found
[16:48:30] <gonzo_> 0x378
[16:48:57] <micges> sudo ./mesaflash --device 7I90 --addr 0x378 --verify filename.bit
[16:49:37] <Connor> So, G for Gscreen, mocca for the Mocca gui, and py for python
[16:50:06] <Connor> so, g-moccoa-py
[16:50:16] <gonzo_> micges, same error
[16:50:20] <Connor> err g-mocca-py
[16:50:57] <gonzo_> micges, nope type. Get comms
[16:51:13] <Connor> need a a glcars
[16:51:29] <gonzo_> verify error, but it's poss I am using the wrong bitfile
[16:51:46] <gonzo_> micges, nope typo. Get successful comms
[16:52:00] <micges> good
[16:52:29] <gonzo_> that's a good first step
[16:52:30] <Loetmichel> Connor: Lcars? is there a working Enterprise-type Desktop ouit there?
[16:52:51] <Connor> Loetmichel: No Clue.. Several people trying to do it..
[16:53:02] <PCW> a small word of advice dont write non-epp or otherwise unknown bitfiles to both EEPROMs
[16:53:15] <Connor> for desktop/ipad/android.. not sure how well they've implemented.
[16:53:32] <gonzo_> noted peter
[16:54:03] <gonzo_> I'm sticking to precompiles images at the mo
[16:54:15] <gonzo_> not risking arseing it up
[16:54:24] <PCW> harder to boostrap...
[16:55:46] <PCW> neither serial nor SPI configs are supported by mesaflash
[16:56:04] <JesusAlos> Some reference of PC+Touchpanel embebed ?
[16:59:21] <Jymmm> PCW: pci only?
[16:59:38] <gonzo_> have deleted all but the epp files from the cnc machine, just to be sure
[17:01:17] <PCW> mesaflash supports flashing PCI/EPP/Ethernet (maybe USB) Mesa FPGA cards
[17:01:34] <gonzo_> just tried programming via mesafdlash, get the reply that the 7I90DH does nit supopoort FPGA resatting
[17:02:01] <gonzo_> 7I90HD
[17:02:02] <PCW> Thats true
[17:02:24] <PCW> you have to power cycle the 7I90 after flashing
[17:02:31] <gonzo_> can I not use mesaflash for that
[17:02:46] <Jymmm> PCW: ah
[17:03:04] <gonzo_> have not programmed it, but will tryb powecycle
[17:03:28] <PCW> Actually the 7I90 should be resettable
[17:04:46] <gonzo_> power cycle, same report
[17:05:08] <micges> gonzo_: --program option send bit file direclty into FPGA, you must use --write to write it to local eeprom and then power cycle 7i90
[17:05:41] <gonzo_> understand, will try
[17:07:41] <PCW> the 7i90 is resettable so the power cycle could be avoided
[17:08:16] <gonzo_> write then verify works ok. Cycle and verify again, also fine
[17:09:12] <micges> gonzo_: I'll improve error messages and README
[17:09:49] <PCW> power cycling reloads the FPGA from the EEPROM
[17:09:50] <PCW> verify is always verifying the file against the EEPROM
[17:10:15] <micges> PCW: resetting info is in doc?
[17:10:38] <PCW> its the same as the 7I43
[17:11:02] <micges> ahh
[17:11:03] <PCW> not sure its documented
[17:11:13] <gonzo_> if you need idiot proofing, I'm your man!
[17:11:37] <PCW> as a matter of fact this is exactly why the hm2_7i43 driver does not work
[17:13:48] <PCW> The hm2_7I43d river resets the FPGA even when no firmware is specified and then
[17:13:50] <PCW> gets a EPP timeout when it tries to access the (busily reloading) 7I90
[17:15:37] <micges> yeah
[17:17:01] <JesusAlos> gn8
[17:37:00] <Connor> https://www.youtube.com/watch?v=nkYpKWbA2P0 @ the 6:04 mark.. he issues a / 2 on the X axis... is there a way to do something like that with linuxcnc ?
[17:37:20] <Connor> not that I like mach or anything, but, that's a nice feature.
[17:40:47] * sabotender hugs Connor
[17:40:49] <sabotender> hiya
[17:41:14] <sabotender> I almost have enough saved for that cnc router, and I am getting pretty excited.
[17:41:44] <Connor> sabotender: Why you hugging me? :)
[17:41:55] <sabotender> because you are cool
[17:42:06] <Connor> Oh, that's news to me.
[17:42:17] <sabotender> what? who doesn't think you are cool?
[17:42:29] <sabotender> and you know more about cnc than I do :-P
[17:42:33] <Connor> I dunno.
[17:42:44] <Connor> Lots of people know more on here about CNC than I do.
[17:42:59] <sabotender> eh? like?
[17:43:41] <Connor> I dunno, andypugh, PCW, cradek, Tom_itx to name a few...
[17:44:21] <sabotender> but the ability to mill pcbs is exceedingly exciting. no toner transfer, no chemicals...
[17:44:22] * sabotender sighs
[17:44:57] <Connor> yup. It is.
[17:45:52] <sabotender> kinda makes me sad that laptops cannot be used for cnc
[17:46:11] <sabotender> I do not *quite* understand why they are so craptastic in that manner
[17:46:26] <sabotender> or maybe it is simply a linuxcnc limitation
[17:46:55] <sabotender> I have seen some machines in videos powered by notebooks/laptops, but they were running mach3 I think it is called
[17:47:08] <Connor> sabotender: Laptops have lots of stuff to make them more energy efficient for battery usage.. They use Interupts and stuff which can mess with RealTime OS
[17:47:46] <sabotender> ah I see, well that makes sense I suppose
[17:48:33] <sabotender> I had to disconnect my server because it was drawing too much power, with being on 24/7 and it was running up my energy bill
[17:48:40] <Connor> Most likely the ones you see running Mach3 are using a offboard controller, which handles parsing the Gcode and generating the pulses to the steppers... and feeding data back to mach3
[17:48:50] <Connor> where as linuxcnc *IS* the machine controller
[17:49:18] <sabotender> wait the entire os is the machine controller?
[17:51:25] <sabotender> is it true that a simple cnc router can cut though thick (insert substrate here) but it would need many passes?
[17:53:23] <PetefromTn_> What Connor NOT COOL???!!! This guy is the COOLEST fellow on here in my view ;)
[17:55:16] <Connor> sabotender: depends.. the diameter of the end mill might play a role... if you use too long of a endmil you might end up flexing (and breaking) the endmil.. and also depends on chip evacuation..
[18:09:23] <andypugh> How thick is thick?
[18:09:59] <andypugh> Eventually the length to diameter ratio of the cutter starts to cause problems.
[18:11:00] <sabotender> andypugh: oh im not sure. greater than an inch in depth?
[18:11:01] <andypugh> But I have cut 20mm deep with a 3mm cutter, and that was in steel.
[18:11:36] <andypugh> An inch is easy. You can do that with a 3mm cutter, in Aluminium, without too much trouble.
[18:11:48] <andypugh> A 6mm cutter would go deeper.
[18:12:08] <andypugh> I thought you were talking about 6” deep with a 1/2” cutter.
[18:12:30] <sabotender> hmm. i dont have any interest in cutting anything more than aluminium
[18:12:33] <syyl--> 25mm with a 1mm endmill ;)
[18:13:03] <sabotender> im not sure the router im getting can even reliably cut aluminium though
[18:13:35] <sabotender> andypugh: http://www.ogowell.com/index.php?main_page=product_free_shipping_info&cPath=5&products_id=143
[18:13:40] <sabotender> I want that one
[18:13:47] <sabotender> so much
[18:14:30] <andypugh> Hmm, I don’t :-)
[18:14:51] <syyl--> my curtains hang on rails that are thicker than those on that machine
[18:14:52] <syyl--> Oo
[18:15:06] <andypugh> Have you looked at benchtop mills? They are likely to machine aluminium better than a router will.
[18:15:23] <andypugh> (Not BCN at that price, though).
[18:15:37] <andypugh> BCN? Where was I on the keyboard?
[18:16:07] <sabotender> andypugh: whats wrong with that cnc router?
[18:16:12] <sabotender> actually, do you know what
[18:16:14] <sabotender> dont tell me
[18:16:19] <sabotender> because I don't care.
[18:16:36] <syyl--> Oo
[18:16:39] <andypugh> I paid about the same price as that router for my real, iron, milling machine (1970s, 4th-hand) and only about another 2.5k converting it to CNC :-)
[18:16:53] <sabotender> its difficult to please anyone in here unless I spend 20K on a cnc mill or something like that
[18:17:09] <sabotender> that darling will suit my purposes
[18:17:52] <andypugh> 20k? You can’t get anything decent for 20k! 200k, second hand, maybe :-)
[18:18:03] <syyl--> sure, machining soft grades of cheese ;)
[18:18:20] <syyl--> if you take light cuts
[18:18:45] <andypugh> Actually, there is a guy on the forum doing OK cutting aluminium on a machine constructed entirely from wood.
[18:19:09] <andypugh> Well, not _entirely_ from wood. Wooden stappers hardly work at all :-)
[18:19:40] <syyl--> ;)
[18:19:42] <syyl--> mh
[18:20:15] <syyl--> a guy at work gave the most cute insert cutter i have ever seen to me ;)
[18:20:22] <syyl--> https://dl.dropboxusercontent.com/u/24396704/QMTL2/IMAG0483.jpg
[18:20:38] <syyl--> 12mm diameter, 5mm inserts
[18:21:44] <andypugh> Ideal for re-creating the look of castings (flat faces, with fillets)
[18:21:58] <syyl--> yeah :D

[18:27:32] <andypugh> sabotender: Here is a video from the guy making aliminium golf cart wheels with a wood-framed router: https://www.youtube.com/watch?v=7nZNuvH7q1I
[18:41:06] <Jymmm> ChuangTzu: I *think* I might have found an alternative to oxiclean at half the cost, waiting for them to email the MSDS =)
[18:41:45] <Jymmm> ChuangTzu: http://www.dollartree.com/20-Oz-Awesome-Oxygen-Cleaner/p8832/index.pro
[18:43:20] <Jymmm> ChuangTzu: And the TSP/90... $5/1LB bag or $11/4LB bag @ Ace Hardware
[18:43:39] <Jymmm> ChuangTzu: In the paint section
[18:52:08] <jdh> sabotender: dunno where you are, but that looks pricey for that work area.
[19:00:30] <sabotender> jdh: it is a bit pricey but it is solidly built
[19:01:06] <sabotender> i havent be able to find one that has the same design for less expensive
[19:07:35] <jdh> what do you like about that particular design?
[19:08:04] <Connor_iPad> Which design. I missed the link. On ipad now.
[19:08:23] <jdh> http://tinyurl.com/lovhvas
[19:09:20] <jdh> 8x7x3 router, no spindle, almost $800
[19:09:54] <Connor_iPad> No bearing blocks on screws either.
[19:10:35] <jdh> oh, it does have that spindle thing at the bottom
[19:11:19] <jdh> sabo: where are you?
[19:12:13] <jdh> it looks like a sable clone
[19:25:18] <andypugh> The web page shows a spindle, but I don’t know why it isn’t shown fitted.
[19:29:20] <andypugh> There are some things about it to like, though I would want to know how the end-thrust on the screws was handled. I was going to comment on the work envelope, but thinking about it, it is actually more than the manual shows for my milling machine!
[19:31:13] <jdh> http://www.ebay.com/itm/201080831373
[19:31:48] <andypugh> Hmm, yes, my INI file says I have 360 x 157 x 265. And that’s normally enough.
[19:33:38] <andypugh> Ones on eBay with a spindle are more expensive, for example: http://www.ebay.com/itm/191148893869?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222003%26algo%3DSIC.FIT%26ao%3D1%26asc%3D22466%26meid%3D6533969978148947273%26pid%3D100005%26prg%3D9735%26rk%3D1%26rkt%3D6%26sd%3D201080831373&rt=nc
[19:33:55] <andypugh> Grr! I didn’t copy all of that!
[19:34:08] <andypugh> http://www.ebay.com/itm/191148893869
[19:34:29] <andypugh> And that’s got a really poor looking spindle.
[19:35:20] <jdh> did you build your wheel?
[19:35:52] <andypugh> No. The spokes haven’t turned up yet.
[19:39:46] <andypugh> I manged to fill the weekend with other jobs, like painting and filling and making rear wheel spindle components. The rear spindle is remarkably compicated, and probably not very good.
[19:40:12] <Connor_iPad> Wheel for what?
[19:41:01] <andypugh> There are a couple of hollow aluminium things go in from each side, each through a fiddly set of spacers and tensioning widgets, and then about 1” into the hollow wheel spindle, then a tie-rod (only 7/16”) goes through the whole thing.
[19:41:28] <andypugh> Drawing here. http://www.geutskens.eu/neracar/300-wheels_assy.htm
[19:42:43] <andypugh> Also, amusingly, when you remove the spokes the hub falls apart into 5 pieces, only the spoke tension holds the parts together!
[19:44:11] <andypugh> Ironically the super-bizarre front end is simpler.
[19:47:23] <andypugh> Goodnight chaps
[20:57:52] <accuartisans> hey, new here. is PCW in the house?
[20:59:10] <PetefromTn_Andro> Evening folks
[20:59:28] <humble_sea_bass> holla back pete
[20:59:43] <PetefromTn_Andro> Hehe
[21:00:20] <PetefromTn_Andro> What are you crazy CNC junkies up to tonight?
[21:01:28] <humble_sea_bass> look over this insane thing i've never seen before that andy posted
[21:01:33] <PetefromTn_Andro> We are supposed to be getting some nasty weather tonight but so far it is pretty calm out.
[21:01:40] <humble_sea_bass> http://www.geutskens.eu/neracar/300-wheels_assy.htm
[21:02:05] <accuartisans> we are supposed to as well! Nort GA
[21:02:08] <humble_sea_bass> http://www.geutskens.eu/neracar/index.htm
[21:02:29] <pcw_home> sort of here...
[21:02:44] <PetefromTn_Andro> Some kinda hub steered wheel assy?
[21:03:22] <accuartisans> @PCW, howdy, well i bit the bullet, got the gigabyte J1800!
[21:03:54] <accuartisans> compiling the 3.14 rt kernel right now
[21:04:15] <PetefromTn_Andro> Accurate so far it is kinda nice outside. Got the windows open but we did put my wife's trooper in the shop in case we get the hail they are squalkin about
[21:05:30] <accuartisans> they say it's going to be nasty after 12 or so last i saw before i came down to the shop and work (in the basement:)
[21:07:07] <accuartisans> @PCW, you wouldn't happen to have and BIOS setup screen shots or parameters you are using at this point would you?
[21:07:21] <humble_sea_bass> http://forecast.io/
[21:07:29] <humble_sea_bass> some bad stuff is coming our way
[21:08:06] <PetefromTn_Andro> Where are you?
[21:08:25] <accuartisans> dawsonville, ga
[21:08:30] <humble_sea_bass> nyc, by bad i mean 3 days of rain
[21:08:38] <pcw_home> No but I did have to update the BIOs to get it to boot Ubuntu at all
[21:09:05] <PetefromTn_Andro> I'm in maryville Tennessee.
[21:09:35] <accuartisans> yep, i have the F3 version
[21:10:52] <pcw_home> I think the main thing is you need to select compatibility mode
[21:12:50] <accuartisans> the CSM? yeah, it took about an hour to figure that out:( It just wanted to boot into the EFI shell. The documentation sucks, but, i am impressed so far.
[21:13:29] <pcw_home> yeah it was painful to get it running the first time but the hardware is pretty nice
[21:14:28] <accuartisans> are you isolating the cpu? as a kernel flag?
[21:14:37] <pcw_home> much snappier than the Atoms...
[21:14:57] <accuartisans> and the AMD 350/450 platform!
[21:15:22] <pcw_home> No I tried but it made latency worse (it my particular environment)
[21:15:45] <accuartisans> that's the same thing i found out on the AMD 350
[21:15:48] <pcw_home> (preemt-RT/Ethernet FPGA card)
[21:16:14] <PetefromTn_Andro> Gn8
[21:16:15] <accuartisans> Yes, I have the 7i80/7i77
[21:16:40] <accuartisans> Gn8?? what's that?
[21:17:02] <accuartisans> nevermind:(
[21:17:44] <pcw_home> gunnite
[21:18:19] <humble_sea_bass> https://www.youtube.com/watch?v=UwpP_s8LV_Y&feature=youtu.be
[21:18:22] <humble_sea_bass> soothing
[21:21:09] <Jymmm> gringing was crazy
[21:32:39] <accuartisans> goodnite
[22:03:00] <Anonymoose> ive recent;y joined a local makerspace and they have a partially complete mini mill/drill with a 4 axis CNC conversion. ive installed LinuxCNC on a machine and was trying to newb my way through the setup but was stumped pretty quickly. i have a tiny bit of informaiton but was wondeirng if anyone had some experience with this sort of thing and could point me in the right direction where I
[22:03:00] <Anonymoose> can read up about it myself. the drivers are k179 and steppers are tamagawa 2.2v 4.6A
[22:05:20] <ChuangTzu> hmm
[22:05:25] <ChuangTzu> seems like i've seen you here before?
[22:05:30] <ChuangTzu> or where have i seen you?
[22:05:31] <ChuangTzu> :S
[22:05:51] <Anonymoose> me? lol i havent been on irc since the days of #vcd on efnet in like 99
[22:05:56] <ChuangTzu> huh
[22:06:09] <Anonymoose> I guess Anonymoose is just universially clever or stupid
[22:06:10] <ChuangTzu> i seriously doubt my memory is that great
[22:06:24] <ChuangTzu> yeah, there must be other such meese
[22:06:25] <ChuangTzu> :S
[22:06:38] <Anonymoose> lol, damned sweedes
[22:08:37] <Anonymoose> and ideas onthe config? there were lots of preconfigured options available, im not sure what drives my config settings. the controller or stepper or both?
[22:12:29] <ChuangTzu> wtf
[22:17:24] <pcw_home> stepconf (not high performance drives so you can use conservative step/dir numbers without any harm)
[22:17:55] <pcw_home> oops already gone
[22:21:35] <ChuangTzu> hmm
[22:21:39] <ChuangTzu> i've never thought of it that way before
[22:21:47] <ChuangTzu> what do you mean by that?
[22:33:01] <pcw_home> longer than needed step timing is not harmful, it just limits you maximum step rate
[22:33:03] <pcw_home> those drives are simple unipolar step motor drives so pretty slow
[22:37:48] <ChuangTzu> pcw_home: if yo use longer than needed step timing with a high performance drive, what happens?
[22:57:54] <Valen> should just run slower
[23:35:48] <Jymmm> ChuangTzu: You see my spam to you?
