[02:08:33] <Deejay> moin
[04:06:23] <RyanS> god australian steel suppliers are infuriating its like a mixture of SAE and Australian Standard specs depending on the product
[04:09:12] <RyanS> although 304 stainless is easier to remember than DIN for eg X5CrNi18-9
[04:12:07] <MattyMatt> it's like that everywhere I think
[04:13:35] <MattyMatt> along with random choice of imperial or metric sizes
[04:15:10] <SpeedEvil> Don't forget not displaying prices
[04:15:37] <MattyMatt> I've got those last 2 things sorted for aluminium
[04:15:58] <MattyMatt> http://www.aluminiumwarehouse.co.uk/Aluminium-T_Section/c120_130/index.html this place is great
[04:16:21] <MattyMatt> has a great website, I should say, I've never ordered
[04:16:48] <SpeedEvil> It's somewhat improving, yes
[04:17:35] <SpeedEvil> http://www.scaffolding-direct.co.uk/ for larger tube
[04:17:59] <RyanS> its annoying witg no price, surely its easier to maintain a price list than "how much for this, do you stock that"
[04:20:18] <RyanS> im designing a welding table based on 'that looks strong enough' and rough pricing from one online supplier with prices
[04:22:01] <SpeedEvil> The problem is there is a twisted rationale in theory.
[04:22:23] <SpeedEvil> It lets them price it ridiculously if you look like you can pay it
[04:23:43] <RyanS> so B2B gets ripped off and DIY/hobbyists get ignored :)
[04:23:49] <MattyMatt> you could go to a scrapyard and look for something that looks suitable
[04:25:41] <MattyMatt> I've got a copper top table, that'd be cool for welding on
[04:25:48] <RyanS> hmm i dont want warped flats (the top is 11 100x12 flat with 12mm t-nut slots
[04:25:56] <MattyMatt> cool until the wood burns of course
[04:27:01] <RyanS> hmm i might have to spray it with anti-splatter or something
[04:27:02] <MattyMatt> there's no guarantee steel you buy will be flat enough
[04:27:50] <MattyMatt> every morning
[04:27:50] <SpeedEvil> MattyMatt: that's why you get a large surface plate as a table.
[04:28:05] <MattyMatt> I wish
[04:28:15] <RyanS> hmm, one supplier . I think specifies 1.6mm +- over 800mm
[04:28:36] <MattyMatt> http://www.ebay.co.uk/itm/CAST-IRON-SURFACE-PLATE-8X4-CAST-IRON-SURFACE-TABLE-ENGINEERS-MARKING-OUT-TABLE-/331547974149
[04:28:49] <RyanS> i can flycut em in stages?
[04:29:39] <SpeedEvil> 'portable type'
[04:29:54] <SpeedEvil> I'd love to know what a non-portable 8*4 surface plate looks like
[04:30:02] <MattyMatt> or find someone with a giant surface table like that. put your ground surfaces down with spacers to make T slots, fill with concrete
[04:30:43] <MattyMatt> or molten iron, if you're hard enough
[04:30:44] <SpeedEvil> 'how did you refurbish it?' Oh - I ran a belt sander over it till it was shiny
[04:31:29] <MattyMatt> looked for light ender his really long ruler
[04:31:35] <RyanS> concrete ?!
[04:31:52] <MattyMatt> concrete is cheap and stable
[04:32:01] <SpeedEvil> MattyMatt: have you seen 'foundations of mechanical accuracy?
[04:32:02] <MattyMatt> not portable
[04:32:28] <MattyMatt> SpeedEvil not with enough attention obviously
[04:32:33] <RyanS> doesn't it go kaboom if welded on?
[04:32:43] <SpeedEvil> http://www.totallyscrewedmachineshop.com/documents/FoundationsofMechanicalAccuracy.pdf
[04:33:00] <MattyMatt> RyanS you make that sound like a bad thing :) good point
[04:33:27] <MattyMatt> everything under the surface slats could be scrap tho
[04:33:56] <RyanS> does it actually explode ?
[04:34:21] <MattyMatt> if it's damp it would
[04:34:27] <RyanS> my design uses 50x50x4mm SHS
[04:34:47] <SpeedEvil> Page 36 - fig 28. Look at the 'insufficiently rigid' ruler :)
[04:35:03] <SpeedEvil> - on the left
[04:35:29] * MattyMatt uses frikken lasers
[04:35:35] <RyanS> so scrap maybe hard to find
[04:36:04] <MattyMatt> try your local scrapyard, you may be surprised
[04:36:25] <MattyMatt> or they might have angle or I beam that'll do
[04:37:10] <MattyMatt> from scrapped steel frame buildingsbuildings
[04:37:17] <MattyMatt> buildingd
[04:38:25] <RyanS> i design with 'that looks ok' and 'i dont know if M8 or M10 bolts should be used so I'd better overkill' principles
[04:38:55] <MattyMatt> I use M8 for clamping, but M10 is better
[04:40:04] <MattyMatt> but with all this M8 hanging around from building repraps :)
[04:40:38] <RyanS> but actually +- 1.6mm straightness is ok for welding on?
[04:40:51] <MattyMatt> slots in my deckel table seem to be 11mm. dunno if that's original or they've been ground out
[04:41:33] <RyanS> I should build a CNC plasma cutter to cut slots :)
[04:41:39] <MattyMatt> that's up to you if 1.6mm is bad, but I'm thinking you can get the whole table flatter than the spec of the strips
[04:43:24] <MattyMatt> and if the strips are that bend, you can straigten them with heat like keith fenner https://www.youtube.com/watch?v=bOT4cSTJyqw
[04:44:00] <RyanS> so my BF30 mill arring next week, 700mm table width, 450mm x travel...... so 850mm flats hmm
[04:44:28] <MattyMatt> flatter table makes layout and set up easier. posh ones are as flat as surface tables
[04:44:45] <RyanS> so id flycut in two stages?
[04:45:07] <MattyMatt> no idea
[04:45:52] <MattyMatt> I do little stuff, and mostly wood so far
[04:57:22] <RyanS> a wooden welding table perhaps :)
[04:59:23] <SpeedEvil> I wish wood would weld.
[04:59:30] <SpeedEvil> Well - grafting, but...
[05:01:54] <archivist_herron> pva glue is as close to a weld as you will get probably
[05:03:24] <XXCoder> boo
[05:04:15] <SpeedEvil> archivist_herron: yeah, I know
[05:05:14] <RyanS> i had no pva once so i used gorilla glue :)
[05:05:39] <RyanS> it *seemed* to work
[05:06:04] <SpeedEvil> Hotmelt is surprisingly good.
[05:06:15] <SpeedEvil> If only it would have a slightly larger temperature range
[05:06:32] <archivist_herron> I find it falls off too easy, like old animal glue
[05:07:14] <zeeshan|2> http://i.imgur.com/MwLzBTf.jpg
[05:07:19] <zeeshan|2> SUCCESS
[05:07:30] <zeeshan|2> i dont know what material this was
[05:07:36] <zeeshan|2> but it was definitely not cold rolled stel
[05:07:41] <SpeedEvil> zeeshan|2: woo
[05:07:55] <RyanS> why do people get a hot glue obsession like people who do craft are hot glue fanatics
[05:08:01] <zeeshan|2> you sniff it!
[05:08:17] <SpeedEvil> RyanS: It's _really_ fast - which is nice
[05:08:32] <SpeedEvil> And more adjustable than CA, and completely demountable with heat and no damage
[05:08:43] <SpeedEvil> faster than CA too often
[05:09:23] <RyanS> sniff it...so theyre literally addicted to hot glue :)
[05:42:48] <dutchfish> hi guys (sorry if i ask the obvious), but where can i modify the parameters for the steppers, like steps per unit (i am using the metric system) and the portconfig for each stepper within in linuxcnc?
[05:44:00] <dutchfish> a link for a newby like me would be nice
[05:44:12] <archivist_herron> you have two files containing the settings, an .ini and a .hal all in the integrators manual
[05:44:38] <jthornton> how did you create the configuration?
[05:44:48] <jthornton> zeeshan|2, nice
[05:44:55] <archivist_herron> a cheat is to use stepconf to create your basic first setup
[05:45:14] <archivist_herron> it creates those two files
[05:45:25] <dutchfish> archivist_herron, thank you very much! thats what i was hoping for
[05:45:27] <jthornton> and a few more files
[05:45:34] <archivist_herron> from then on hand edit
[05:46:11] <dutchfish> archivist_herron, the 2.6.8 one?
[05:46:25] <archivist_herron> whatever version you are using
[05:46:36] <dutchfish> archivist_herron, let me check
[05:46:54] <dutchfish> archivist_herron, 2.6.0
[05:47:27] <archivist_herron> whatever stepconf will already be there, could be time to update it too
[05:47:39] <dutchfish> error 2.6.6
[05:47:51] <dutchfish> i see there are bug fixes in the chagelogs
[05:47:56] <dutchfish> changelogs
[05:48:24] <dutchfish> what would you recommend me? 2.6.8?
[05:48:44] <dutchfish> i need to install it again from scratch anyway
[05:49:41] <dutchfish> since my old pc just gave up on me
[05:50:11] <archivist_herron> 2.6.8 then
[05:50:15] <dutchfish> ok
[05:50:20] <dutchfish> archivist_herron, thanks again
[05:53:21] <dutchfish> archivist_herron, last q, is there an iso for 2.6.8? or is it still 2.6.4?
[05:53:46] <archivist_herron> that I dont know
[05:53:47] <dutchfish> nm, i just can upgrade
[05:54:09] <dutchfish> i dont need to redownload and burn it again
[05:54:27] <dutchfish> sorry
[06:18:54] <dutchfish> i am running the live system as a test with the latency test 42000 max jitter, its a duo core with 1G mem, is that a suitable system?
[06:19:24] <dutchfish> (with glxgears running and some other things)
[06:23:04] <jthornton> http://linuxcnc.org/docs/html/config/stepconf.html#_latency_test_a_id_latency_test_a
[06:25:28] <dutchfish> jthornton, thanks :)
[06:26:03] <jthornton> yw
[06:26:42] <jthornton> the rain has started...
[06:36:48] <dutchfish> jthornton, i already tested the setup with mach3 while building the cnc, that part is done now, so i want to install linuxcnc for the real work, now i have gained enough knowledge of machining parts
[06:49:16] * archivist_herron giggles, mach for testing, linuxcnc for real work
[06:50:36] <dutchfish> archivist_herron, well, i use debian jessie currently for the cad cam part, so its obvious to do the cnc part as well in the same envirenment which i am comfortable in
[06:51:18] <dutchfish> archivist_herron, i just have a steap learning curve about cnc maching in general ahead
[06:51:39] <archivist_herron> have you done manual machining?
[06:51:47] <dutchfish> archivist_herron, a bit, yes
[06:52:01] <dutchfish> archivist_herron, on a siege X3
[06:52:34] <archivist_herron> that helps a lot, you then have an idea of speeds and feeds and the noise a cut should make
[06:52:52] <dutchfish> archivist_herron, i am still a newb, but yes
[06:53:32] <dutchfish> so far no fire-extinguishers were needed
[06:53:57] <archivist_herron> a race to the stop button is common :)
[06:54:49] <dutchfish> well, i must admit i didnt even need to use that one, but i broke some mills in the process
[06:55:42] <dutchfish> mostly because the feed ins and feed out's were wrong
[06:56:00] <dutchfish> (just forgot to incorperate them)
[06:57:37] <dutchfish> some of my experiments in jessie http://www.yellowsource.org/screenshots/
[06:58:32] <archivist_herron> we have all broken something
[06:58:43] <dutchfish> ;)
[07:01:27] <SpeedEvil> I broke my wookie.
[07:01:41] <dutchfish> wookie?
[07:01:54] <SpeedEvil> nvm. (simpsons)
[07:02:00] <dutchfish> ah ok, gotcha
[07:02:10] <dutchfish> dough
[07:15:34] <dutchfish> ok, i have just installed from the iso, i am on wheezy (completely updated) to the 3.4.-9-rtai kernel, but linuxcnc is still 2.6.1, how to upgrade to 2.6.8?
[07:16:54] <dutchfish> does it have a separate repo?
[07:24:11] <dutchfish> nevermind i need to redownload the iso after all, to get it to 2.6.4 then upgrade, dough
[08:04:51] <JT-Shop> andypugh, always comes up with the clever ideas :)
[08:05:11] <archivist> what he do now :)
[08:05:35] <archivist> spindle at speed?
[08:05:43] <JT-Shop> forum post
[08:06:00] <archivist> I never browse there too slow
[08:07:34] <JT-Shop> I speed read so I miss a lot on slow forums
[08:27:36] <nema34> morning
[08:32:24] <nema34> hi sumpfralle
[09:14:32] <PetefromTn_> Morning fellow linuxCNC Junkies!
[09:28:43] <furrywolf> I'm not a junkie! I can stop whenever I want to!
[09:30:23] <PetefromTn_> SURE
[09:42:11] <dutchfish> hi, i have managed to reinstall, with the latest iso-hybrid and update my system to 2.6.8, i have walked through the manual, to setup my par port, but it seams alot of ports the wizard want them to be inputs instead of outputs, see my table for the partports http://www.yellowsource.org/screenshots/steppermotorsetup.png , how to do that? specially i am confused about the enable ports which seams to be m
[09:42:17] <dutchfish> issing in the wizzard.
[09:43:37] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/laser-engraving/40w-co2-laser-machine-software-training anyone know the spot size for this or similar import CO2 engravers?
[09:48:51] <dutchfish> is or is X enable equivalent to amplifier enable?
[09:49:56] <CaptHindsight> dutchfish: it can be used for amp enable
[09:51:41] <dutchfish> CaptHindsight, ok, thanks, i will try that
[09:52:11] <CaptHindsight> http://upload.wikimedia.org/wikipedia/commons/thumb/e/e0/Parallel_port_pinouts.svg/350px-Parallel_port_pinouts.svg.png
[09:53:07] <CaptHindsight> as you can see some ports are only Inputs or Outputs and only 4 are Bidrectional
[09:53:09] <nema34> I need soe help with modify heat sink.
[09:53:15] <nema34> some*
[09:53:23] <CaptHindsight> what help?
[09:53:42] <nema34> dutchfish: very impressive qrz page!
[09:53:58] <dutchfish> nema34, oh, thanks 73
[09:54:24] <nema34> dutchfish: 88
[09:55:29] <nema34> I'm a tech, and my BF is extra
[09:56:01] <dutchfish> :)
[09:56:47] <nema34> but your more in to rf than we are.
[09:57:37] <dutchfish> well, i am sometimes a teacher, work in IT, studied chemistry and marinebiology, do radio amateur (licensed), and develop kernel stuff and like Debian
[09:58:16] <dutchfish> i am however new to cnc
[09:58:24] <nema34> very nice!
[09:59:03] <dutchfish> so bare with me if i ask the obvious ....
[10:00:05] <nema34> I'm also fresh to cnc, but l'm lerning now to engineer degree, and more in to modeling and stuff like that.
[10:00:20] <dutchfish> nema34, excellent
[10:00:26] <nema34> I have G0407 with high power servo motors
[10:01:12] <nema34> now I'm wating to the computer.. rendering soo sloow.
[10:01:26] <nema34> GT9400 :(
[10:01:29] <dutchfish> nema34, my setup is now misumi actuators and 2 thk's for the xy axis in total 4 axis, but my interface can for the time being just do 3
[10:02:03] <dutchfish> nema34, enough to get my hunger for alu radio parts stilled ;)
[10:02:43] <nema34> to you want to machine metals or just soft materials?
[10:02:44] <dutchfish> nema34, at least, that is what i hope to accomplish with the setup i am building
[10:03:09] <dutchfish> nema34, aluminium, hard plastics, expoxy boards, thats mostly it
[10:03:26] <dutchfish> nema34, for pcb's frontpanels and small alu-parts
[10:03:39] <nema34> and what you are plan to use as a spindle?
[10:04:23] <nema34> i like aluminum. the machine eat it like crasy..
[10:04:27] <dutchfish> nema34, i use now a KRESS 1050 FME-1 , but ordered a watercooled BLDC with controller from Siemens 2.2kW
[10:04:52] <dutchfish> nema34, the kress has too much rpm to my likings
[10:05:23] <dutchfish> nema34, the min is 5000rpm and the power output is then to low
[10:05:37] <nema34> my spindle is the original that come with the machine just 1hp, up to 1900 rpm
[10:06:00] <dutchfish> nema34, nice
[10:07:09] <nema34> in my case if I'm try to take high chip load the mahcine feel flexible.
[10:08:11] <dutchfish> nema34, yes, my first expiriment without the actuators and guidances gave pretty simular results
[10:08:26] <nema34> and it is almost quarter of a ton
[10:08:40] <nema34> probbly more with the motors..
[10:09:04] <dutchfish> hihihi, yes, weight can be an issue for a sturdy setup too
[10:09:08] <norias> you probably should match drive motors to spindle
[10:09:25] <norias> but, eh, i never sat down to do the machine design problems
[10:09:53] <nema34> the machin is heav top.
[10:09:58] <dutchfish> well, my setup is rigid now, but it breaks mills easely
[10:10:14] <norias> why do you think that is?
[10:10:33] <dutchfish> norias, to high feed rate i gues
[10:10:40] <norias> not a bad guess
[10:10:50] <norias> ever measure runout at the spindle?
[10:10:53] <dutchfish> norias, or to low spindle rpm for that feed
[10:11:17] <archivist> climb milling on a flexible machine or one with backlash too
[10:11:26] <nema34> frobably off center + hight chip load
[10:12:09] <archivist> probably most cutting is off centre
[10:12:13] <dutchfish> i gues with more torque and less rpm for the spindle it will go better in harder materials like machined stell parts or brons
[10:13:02] <nema34> I mean the backlesh make the end mill to vibrate
[10:13:06] * dutchfish is studying the machinist handbook day by day now
[10:13:46] <dutchfish> nema34, i have no problem anymore with vibrations
[10:13:52] <archivist> back lash means the cutter can pull the machine too deep when climb milling
[10:14:04] <dutchfish> archivist, very true
[10:15:02] <dutchfish> archivist, that ended one of my mills in a former setup
[10:15:29] <nema34> or make it jump profile milling (side)
[10:16:18] <nema34> I'm more than a year work just manual.
[10:16:24] <archivist> cam programs usually use climb milling for its better finish, but old manual machines were operated with conventional milling so they pushed apart to avoid that problem
[10:16:51] <archivist> I write my gcode to use conventional
[10:17:05] <dutchfish> archivist, manually?
[10:17:17] <archivist> yes
[10:17:27] <dutchfish> oh wow, i want to learn that to one day
[10:17:54] <archivist> linuxcnc has loops etc so can be expressive
[10:18:05] <dutchfish> really?
[10:18:15] <dutchfish> i will delve into that
[10:18:24] <archivist> and conditionals and variables etc
[10:18:55] <dutchfish> it would be nce to have something that produces for example gcode on the fly for a pocket operation and then manually alter it to my needs
[10:19:00] <dutchfish> nice*
[10:19:02] <nema34> the rendering kill my computer :(
[10:19:13] <nema34> I've stop it. :((
[10:19:33] <archivist> dutchfish, there are some plug in wzzards for that
[10:19:48] <dutchfish> archivist, nice, i delve into that too as a next stop
[10:20:24] <dutchfish> archivist, i have seen this done somewhere with python code
[10:20:35] <dutchfish> but i cant remember where
[10:20:49] <archivist> I think python is the hard way :)
[10:21:21] <dutchfish> nema34, i solved rendering problems with inserting an ATI card and using the opensource code inside wheezy for the drm setup
[10:22:31] <dutchfish> nema34, rv60x do run hw accelerated out of the box in wheezy
[10:23:08] <dutchfish> archivist, how you did it?
[10:26:23] <archivist> for gears I have a bit of gcode to step the rotary and cut on another axis, just has constants and some loops
[10:27:06] <dutchfish> archivist, wow, you should make a wiki for that or a vid, excellent
[10:27:45] <archivist> it is this simple http://www.archivist.info/cnc/standard_clock_n_teeth.ngc
[10:29:23] <dutchfish> archivist, for you it is simple, for me: i have to learn the intrensics of gcode first ;) but i safe it for later. Thanks!
[10:29:59] <archivist> note that assumes my machine and axis directions etc
[10:30:08] <dutchfish> archivist, noted
[10:30:42] <archivist> my machine before it gained an axis too :)
[10:31:43] <dutchfish> archivist, apropos nice things on your homepage! kudos
[10:33:15] <archivist> eg even some of the maths for this can be crammed in the gcode constants http://www.archivist.info/gear/designbevel.php
[10:34:01] <dutchfish> archivist, wow, now we are cooking. Nice.
[10:34:42] <archivist> note the E&OE at the bottom, some work to finish off
[10:35:07] <dutchfish> its totally out of my lague, but i will digest it later
[10:38:16] <nema34> http://i.imgur.com/xshJ5Sp.png
[10:38:31] <nema34> i need some help with the modification in pink/
[10:39:36] <archivist> nema34, can you ask better questions
[10:41:25] <nema34> I've modeled the heatsink that i talk about it yesterday, and i need to trim the L shape brackets, and drill 4 holes
[10:42:12] <nema34> archivist: ^
[10:43:21] <archivist> help us help you, solidworkd problem, or linuxcnc problem or what
[10:48:55] <nema34> this is how the heat sink look like now, (except of the holes of of course), - what it the steps that i need to do to make get code that will remove the L brackets and will drill the holes, and after I put the part in the vise, how I tell Linux cnc where it is. so it will drill it and trimm it precisely.
[10:48:59] <nema34> archivist: ^^
[10:49:04] <nema34> dutchfish: ^
[10:49:56] <archivist> learn to touch off to find the 0,0 position
[10:51:21] <archivist> is this a one off job or production
[10:51:22] <nema34> some guide? something?
[10:52:47] <archivist> there are few if any guides for specific jobs
[10:54:12] <archivist> most of use would use the mdi mode to drill at certain offsets x,y
[10:54:21] <nema34> I've allredy crash one heatsink yesrday, and the machine is VERY dangerous tool, so to keep self lerning and crash stuff that fly here at home - it is not a sulotion.
[10:54:50] <dutchfish> nema34, i wouldnt be of much help since i am using freecad and heeks
[10:55:19] <nema34> I can import the part to free cad?
[10:55:31] <dutchfish> nema34, what form is your file in?
[10:55:51] <nema34> solidpart.
[10:55:55] <dutchfish> nope
[10:56:06] <nema34> It's made in solidworks.
[10:56:30] <dutchfish> nema34, http://www.freecadweb.org/wiki/index.php?title=FreeCAD_Howto_Import_Export
[10:57:45] <dutchfish> nema34, i gues converting it to meshes and then import could be done, but thats more work then finding out how to do it in your cad system
[10:58:19] <dutchfish> nema34, STEP files is another option
[10:58:27] <nema34> after the crash yesterday, I'm really ting about thaking some real course.
[10:58:56] <dutchfish> nema34, you dont want to know how many hours i already did spent in learning some cad systems ;)
[10:59:11] <dutchfish> (still learning)
[10:59:24] <nema34> step 203 or 214?
[11:00:03] <dutchfish> nema34, for now i am using all on linux qcad, librecad, freecad, heekscad and some CAM tools
[11:00:18] <nema34> at the cad I have some luck because I've alredy use it in work, so for me it was very natural.
[11:00:34] <dutchfish> wow, nice
[11:01:55] <nema34> but all the stuff that i made sent to profesional cnc worker. so I've never touch the cnc stuff.
[11:02:25] <dutchfish> nema34, i am in the same boat, to bad i cant help you directly
[11:03:59] <dutchfish> basically what you want boils down to make a face in the right plane attach a sketch for a pocket or boolean
[11:04:36] <nema34> the stuff thet I've alredy learn about cnc is how good heatsink can fly when 1HP spindle fly crash on the side of it.
[11:04:42] <dutchfish> i havent the fanetest idea how that is done in your cad system
[11:04:58] <dutchfish> rofl
[11:05:17] <nema34> I was not funny at all!
[11:05:47] <dutchfish> nema34, also never ever try to gues the temperature of the spindle by touching it ;)
[11:05:55] <dutchfish> <-- i did
[11:06:37] <nema34> I hope you are going to build safe control box.
[11:06:45] <dutchfish> nema34, yes
[11:06:59] <dutchfish> nema34, and i have a remote temp sensor now
[11:07:49] <nema34> my machine is going to based on self holding main contactor, with 2 stage of limit switches.
[11:07:58] <nema34> 1 stage go to the computer.
[11:08:11] <nema34> 2 stage go to the E-stop loop.
[11:09:08] <nema34> if the 2 stage brake the main contuctor disconnect and shutdown the whole machine.
[11:12:27] <nema34> any one have any idea how to solve it and creat the post procesor?
[11:12:28] <nema34> http://linuxcnc.org/index.php/english/forum/31-cad-cam/1307-solidcam-to-emc2-post-processor?start=30
[11:18:53] <nema34> someone here use solidcam?
[11:48:46] <zeeshan|2> has anyone here machined delrin or ptfe ?
[11:49:33] <archivist> might have used delrin
[11:50:07] <archivist> hard to know sometimes
[11:50:08] <zeeshan|2> i need a flanged bearing for my clutch pedal assembly
[11:50:16] <zeeshan|2> was thinking of turning my own since it might be faster
[11:50:49] <archivist> effin sharp tooling needed
[11:51:12] <zeeshan|2> i have some ccgt inserts
[11:51:23] <zeeshan|2> positive rake
[11:51:27] <archivist> I would forget inserts
[11:51:27] <zeeshan|2> very sharp
[11:51:37] <SpeedEvil> nice HSS razor
[11:52:22] <zeeshan|2> i can use ptfe, delrin , nylon
[11:52:41] <archivist> do not let the plastic heat up either, it sure expands lots
[11:53:46] <archivist> I was making wrinkle wall disks ... oops
[11:57:17] <zeeshan|2> maybe ill just use bronze bearings :/
[11:58:14] <archivist> I am always grinding bits of hss these days
[11:58:38] <archivist> for one offs faster than futzing with inserts
[12:10:11] <zeeshan|2> https://www.youtube.com/watch?v=9gXGE-hOECM
[12:10:16] <zeeshan|2> man i want something like this for the 300C oven
[12:10:37] <zeeshan|2> theres gotta be a material that takes 300C and comes in a round form and can be easy to bend
[12:14:25] <nema34> zeeshan|2: it is your video?
[12:14:28] <zeeshan|2> no
[12:15:12] <nema34> I don't know what to do with the machine.
[12:15:22] <PetefromTn_> machined and turned tons of delrin cuts like butter..
[12:15:33] <zeeshan|2> PetefromTn_: what kind of tooling?
[12:15:46] <nema34> I'm soo lost :(
[12:15:47] <zeeshan|2> for turning
[12:15:58] <PetefromTn_> as said just some sharp tools works fine.
[12:16:08] <PetefromTn_> have used inserts as well with no problems.
[12:16:16] <zeeshan|2> ok i just dont wanna change tools :P
[12:16:19] <PetefromTn_> mostly hand ground
[12:16:35] <zeeshan|2> im thinking ptfe will machine similar to delrin
[12:16:37] <archivist> you can get ground inserts for extra monyz
[12:16:46] <zeeshan|2> archivist: trying to use what i have
[12:17:06] <zeeshan|2> i went through making a fixture to make those fish eye spacers cause i was too cheap to buy a 5c collet block
[12:17:06] <zeeshan|2> haha
[12:17:17] <nema34> you can use some mist. but PTFE can hold some temperature
[12:17:37] <PetefromTn_> http://i.imgur.com/cm8f03W.jpg
[12:17:45] <zeeshan|2> sexy
[12:17:51] <zeeshan|2> i like that toool path
[12:18:19] <PetefromTn_> http://i.imgur.com/ITTVAIm.jpg
[12:18:30] <PetefromTn_> not too shabby....;)
[12:18:36] <nema34> I'm in deep depression
[12:18:58] <archivist> if your cutter is not sharp enough, fuuuurrrrbies http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_07_18_Fan_gears/IMG_1267.JPG
[12:19:59] <zeeshan|2> haha
[12:20:22] <nema34> what can I do with the machine?
[12:20:31] <PetefromTn_> damn are those 3d printed or something?
[12:20:36] <archivist> nema34, anything you want
[12:20:52] <archivist> PetefromTn_, no, cut on the 5 axis
[12:21:04] <nema34> now I just want it to machine something.
[12:21:17] <nema34> without make it fly.
[12:21:43] <archivist> go to a local college to learn machining
[12:21:43] <nema34> I can't undertend the gcode.
[12:22:00] <archivist> try it cutting air first
[12:22:00] <nema34> I'm realy want to make it work with solidcam.
[12:22:23] <nema34> I try it.
[12:22:40] <zeeshan|2> PetefromTn_: how do you have patience to chamfer on the machine? :)
[12:22:53] <PetefromTn_> what do you mean?
[12:23:07] <zeeshan|2> it takes extra time! :P
[12:23:09] <nema34> and I try also paper with marker - and it type the linux cnc logo very nice.
[12:23:15] <PetefromTn_> champfer ops are just seconds really
[12:23:20] <sysdef> someone is milling/lathing gorilla plastic here? i thought it's a cheap material since you can reuse it again and again
[12:23:28] <zeeshan|2> i shot some videos yesterday of machining some stuff
[12:23:44] <nema34> but i don't able to bring code from solidcam to the machine.
[12:24:22] <PetefromTn_> on your machine?
[12:24:59] <nema34> PetefromTn_: what cam program you use?
[12:25:23] <PetefromTn_> CamBam
[12:25:53] <zeeshan|2> whats a free & easy to use video editting software
[12:25:54] <nema34> It has collision detection?
[12:25:58] <zeeshan|2> mostly for transitioning between videos
[12:26:49] <PetefromTn_> saw your throttle body video..
[12:27:12] <zeeshan|2> that was such a dull video haha
[12:27:20] <nema34> ?
[12:27:30] <zeeshan|2> i wanna be able to fast forward through some machining
[12:27:30] <archivist> plain cut can be less jarring than fades and other ....
[12:27:31] <PetefromTn_> how did you located those bores and are they straight bores or tapered?
[12:27:32] <zeeshan|2> that would be nice
[12:28:05] <PetefromTn_> microsoft has a video editor I have used works decent
[12:28:05] <zeeshan|2> they are flat where the butterfly shaft goes through
[12:28:14] <zeeshan|2> i mean round not flat
[12:28:37] <zeeshan|2> i bolted the tb down square by eye to the table, then dialed one bore in with the indicator
[12:28:38] <PetefromTn_> how did you located the holes?
[12:28:40] <zeeshan|2> zero'ed
[12:28:49] <zeeshan|2> moved to the next hole, dialed it in, noted the position
[12:28:54] <zeeshan|2> and then the 3rd hole same thing
[12:28:57] <PetefromTn_> aah
[12:29:02] <zeeshan|2> then used those coordinates and made a helical boring path
[12:29:03] <PetefromTn_> works for me
[12:29:13] <zeeshan|2> yea you dont need to worry about it being square that way
[12:29:16] <nema34> PetefromTn_: cambam just make the gcode, or it's also simulate the machine?
[12:29:21] <PetefromTn_> I have been doing a lot of manual digitizing like that LOL
[12:29:33] <zeeshan|2> PetefromTn_: try to bore those tbs?
[12:29:39] <zeeshan|2> you can make 350
[12:29:49] <zeeshan|2> you hang out with those rx7 guys
[12:29:50] <PetefromTn_> CamBam just allows you to make G-code they have a free simulator program that goes with it or there are others online.
[12:30:07] <zeeshan|2> if i were to go back and do it, id use a boring head
[12:30:07] <PetefromTn_> ?
[12:30:30] <PetefromTn_> Kinda surprised you did not try to taper the bore towards the top ;)
[12:30:43] <zeeshan|2> or helical bore with end mill then hone it after
[12:30:59] <zeeshan|2> i didnt cause he already manually ported the transition by hand, so it was going to be hard to blend
[12:31:01] <PetefromTn_> is that for an RX7?
[12:31:16] <zeeshan|2> i just did round holes then used sand paper to blend the entry
[12:31:20] <zeeshan|2> yes
[12:32:46] <nema34> someone here from NY/NJ/PA?
[12:33:33] <nema34> I'm in NY
[12:33:54] <t12> l
[12:34:25] <nema34> ?
[12:47:23] <PetefromTn_> Never looked at the throttle body really..
[13:49:36] <nema34> solidcam show the part inside the table instade of on the table.
[13:54:04] <jthornton> nema34, look on the user map
[13:57:03] <nema34> http://i.imgur.com/VOFTTky.png
[13:57:10] <nema34> jthornton: ^
[14:03:26] <zeeshan|2> fastenal is retarded
[14:03:29] <jthornton> I have no idea why you wanted to waste my limited bandwidth with that image
[14:03:45] <zeeshan|2> i call in and the first thing they say is we don't sell to residential
[14:03:45] <zeeshan|2> wtf?
[14:03:50] <zeeshan|2> what made them think i wanted it for residential
[14:03:50] <zeeshan|2> lol
[14:03:56] <zeeshan|2> i need some shoulder bolts
[14:04:19] <jthornton> sounds like he needs an attitude adjustment
[14:04:30] <zeeshan|2> i get this attitude from most astenal stores
[14:04:34] <zeeshan|2> its a terrible company
[14:04:40] <zeeshan|2> getting sick of it :/
[14:04:42] <jthornton> and he is full of it cause they sell to anyone with money
[14:04:54] <jthornton> it ain't the company it's your local guy
[14:05:04] <zeeshan|2> ive called 3 different stores today
[14:05:07] <zeeshan|2> they have so much attitude
[14:05:12] <jthornton> my fastenal is great cause the guys working there are great
[14:05:15] <zeeshan|2> ah
[14:05:36] <Jymmm> zeeshan|2: If you worked there, you would have an attitude too =)
[14:05:51] <jthornton> they don't pay well
[14:08:44] <zeeshan|2> only reason i called them is cause i saw stock.
[14:08:50] <zeeshan|2> so i was like okay, ill just pick it up today
[14:09:04] <zeeshan|2> called my main go to store and they're so awesome.. "9am tomorrow morning"
[14:09:22] <zeeshan|2> having a poor attitude because you're not getting paid well is no excuse, find a new job.
[14:18:06] <Jymmm> zeeshan|2: "Fuck you and your suck attitude!"
[14:21:39] <Jymmm> Has anyone seen one of these in operation/used one? http://www.amazon.com/Iwatani-Stainless-Household-Outdoor-Barbecue/dp/B00DGWWQ56/
[14:25:18] <Tom_itx> local fastenal is ok but i don't go there much
[14:25:55] <Tom_itx> zeeshan|2 you didn't have 'ass' written on your forehead when you went in did you?
[14:26:54] <Tom_itx> ok i'm determined to get this control working...
[15:22:23] <JT-Shop> Tom_itx, having fun?
[15:36:21] <Jymmm> Heh, lpg brazing =)
[15:37:31] <Jymmm> I like his "cross slide vise" (end of video) https://www.youtube.com/watch?v=gsiOtYPny_k
[16:11:10] <PetefromTn_> The Fastenal by me is pretty damn good and they sell to everyone... Must be a Canada thing LOL
[16:13:09] <malcom2073> Yeah the one near me is amazing, they always have what I need, and they sell to anything. I blame Canada :P
[16:13:14] <malcom2073> to anyone*
[16:16:05] <Jymmm> I blame canada for everyone too
[16:16:12] <Jymmm> ;)
[16:17:29] <malcom2073> "It's ok, I have canadian friends, they're ok with it"
[16:17:38] <Jymmm> lol
[16:19:57] <PetefromTn_> those CRAZY CANADIANS!!
[16:22:39] <Deejay> gn8
[17:54:36] <Tom_itx> JT-Shop, absolutely
[17:55:04] <Tom_itx> i moved the 7i84 so hopefully the serial signal will be better isolated
[17:55:17] <Tom_itx> gonna test after i feed
[17:55:47] <Tom_itx> if this doesn't work, all the io is going back on the 7i90
[18:05:06] <Jymmm> Tom_itx: Just put everythign down and walk away. Go grab a beer/hooker/ice cream, whatever, just walk away for a few.
[18:15:36] <PCW> Tom_itx: I still suspect a a serial wiring error, the differential RS-422 com is very robust
[18:24:20] * JT-Shop made a simple G code from HSMExpress so it is time to veg
[18:35:05] <Tom_itx> PCW i haven't rewired the serial since i added the board. i seriously doubt it's wired wrong
[18:57:08] <Tom_itx> i did just verify the wiring though
[18:57:39] <Tom_itx> using mesaflash for the software side
[19:05:56] <Tom_itx> still get invalid cookie
[19:12:05] <micges> Tom_itx: what's the problem with cookie?
[19:14:48] <Tom_itx> hm2_7i90.0.7i84.0.0 error = (1) invalid cookie
[19:17:19] <Tom_itx> DoIt not cleared from previous servo thread. Servo thread rate probably too fast......
[19:18:09] <Tom_itx> SERVO_PERIOD = 1000000
[19:18:32] <micges> did you put read at first place and write at end of addf list?
[19:19:14] <Tom_itx> not sure what you're asking
[19:20:27] <micges> hm2_7i90.0.read must be first in hal and hm2_7i90.0.write must be last
[19:20:34] <micges> to sserial to work
[19:22:36] <Tom_itx> those lines are in the hal file
[19:22:46] <Tom_itx> do all the addf need to be between them?
[19:22:54] <micges> yes
[19:23:10] <Tom_itx> wasn't aware of that
[19:23:27] <Tom_itx> what about loadrt?
[19:24:08] <micges> no, just addf order is important
[19:25:58] <Tom_itx> any certain order of addf commands?
[19:28:04] <Tom_itx> i didn't know they had to be between those
[19:28:21] <micges> generally should be: mesa read, motion command, motion controller, all rest, mesa write
[19:29:57] <Tom_itx> it would be nice if the addf doc mentioned that
[19:32:03] <PCW> invalid cookie means the serial interface is very badliy broken
[19:34:04] <Tom_itx> i'll beep test all the wiring. i checked the wiring and it's wired right. i'll check for a broken wire etc now
[19:35:10] <PCW> you can also check the differential voltage across +TX and -TX and +RX and -RX
[19:36:16] <Tom_itx> 3.29 and 4.51v
[19:39:31] <Tom_itx> wires all beep test from plug to screw head
[19:40:03] <PCW> still something major broken
[19:40:14] <Tom_itx> no idea what.
[19:40:32] <PCW> I dont think Ive see a cookie error ever
[19:40:46] <micges> Tom_itx: what's output from mesaflash --readhmid
[19:43:11] <PCW> marginal power somewhere might do this, bad flat cable maybe a bad cookie error (and shutting down the link) mean the 7I90 can just barely communicate with the 7I84
[19:45:07] <Tom_itx> the flat cable is about 3" long
[19:45:13] <Tom_itx> maybe 3.5
[19:45:27] <PCW> I would check the 5V cable power at the 7I84, something funky there could cause trouble
[19:45:29] <Tom_itx> just enough to span the 2 boards
[19:46:13] <Tom_itx> 4.96v
[19:46:30] <PCW> bad bitfile somehow maybe
[19:46:51] <Tom_itx> looks ok
[19:47:02] <PCW> did it meet timing?
[19:47:08] <Tom_itx> afik
[19:47:39] <Tom_itx> i'm working on the hal file a bit then i'll try it again
[19:47:49] <PCW> weird, definately something broken
[19:48:27] <PCW> This is through a 7I47S?
[19:50:55] <Tom_itx> yes
[19:51:33] <PCW> RX termination enabled?
[19:53:09] <Tom_itx> now it fails on the hm2....0.read line
[19:53:23] <Tom_itx> lemme look
[19:57:05] <Tom_itx> is that W10?
[19:57:17] <Tom_itx> no W11
[19:58:07] <Tom_itx> W11 is to the left
[20:00:52] <PCW> 3.29V seems high if the 7I84 is driving a terminator
[20:04:36] <PCW> (since its a 3.3V RS-422 interface chip on the 7I84)
[20:04:44] <atom1> http://paste.debian.net/177258/
[20:05:01] <Tom_itx> micges there's the output file
[20:06:09] <Tom_itx> rx on 13 tx on 22
[20:06:59] <Tom_itx> PCW, lemme check if i got the right jumper
[20:07:54] <Tom_itx> IO13 woulb be RX10 IO22 would be TX2
[20:09:46] <Tom_itx> i think i told you the wrong jumper
[20:10:08] <Tom_itx> W11 is for RX10 which is to the left
[20:11:09] <PCW> still odd (3.29V is really not possible from a 3.3V driver into a 120 ohm termination)
[20:12:05] <Tom_itx> i might be able to move it to another RX pair
[20:12:11] <Tom_itx> not sure
[20:15:21] <Tom_itx> across P3-12 & 13 is 3.3v across P3 19-20 is 4.51
[20:15:54] <Tom_itx> 12 & 13 is RX10
[20:16:04] <Tom_itx> 19 & 20 is TX2
[20:23:33] <PCW> weird sounds like termination is not working
[20:24:10] <PCW> pull the jumper when measuring the diff voltage
[20:25:54] <Tom_itx> still 3.29 across pins 12-13
[20:25:57] <Tom_itx> on P3
[20:26:03] <Tom_itx> W11 jumper
[20:26:14] <PCW> bad connector?
[20:26:30] <Tom_itx> doesn't look bad
[20:26:32] <Tom_itx> i can swap it
[20:27:39] <Tom_itx> different jumper 3.3v
[20:37:29] <PCW> Just checked here, I get 3.3V no term 2.7V with term
[20:37:50] <PCW> sounds like theres an open somewhere
[20:42:31] <Tom_itx> once i get the config in order i'll see if i have another free pair to try
[20:48:11] <Tom_itx> now that you mention it, i was using sserial on the 7I47 before, not the 7I47S
[20:48:23] <Tom_itx> just thought of that
[21:26:25] <Tom_itx> i can move it to RX11
[21:27:29] <Tom_itx> IO15
[21:27:59] <Tom_itx> which jumper is for RX11?
[21:28:22] <Tom_itx> W5?
[21:28:56] <Jymmm> JT-Shop Got a bbq for ya... http://www.amazon.com/Iwatani-Stainless-Household-Outdoor-Barbecue/dp/B00DGWWQ56/
[21:34:13] <Tom_itx> pcw_home, with the jumper W5 on RX11 i get .103v
[21:38:14] <Tom_itx> generating bit file
[21:39:04] <Tom_itx> pcw_home, do you know what resistor that is on W11?
[21:39:09] <Tom_itx> maybe i can check it
[22:32:11] <Tom_itx> ok bitfile fixed and loaded. i'll test it tomorrow
[22:46:55] <zeeshan|2> :D

[22:47:04] <zeeshan|2> success
[23:01:07] <sector_0> do you guys think it's possible to build a CNC mill out of aluminum?
[23:01:46] <sector_0> one that can mill aluminum at most
[23:01:56] <sector_0> would it be rigid enough?
[23:02:19] <zeeshan|2> yea
[23:02:35] <t12> define enough i guess
[23:02:36] <zeeshan|2> you can design aluminum to be silly rigid
[23:06:18] <sector_0> cool
[23:07:44] <zeeshan|2> that was a quick q and exit
[23:07:45] <zeeshan|2> lol
[23:10:47] <roycroft> i wonder if i can build a cnc mill out of yogurt
[23:10:50] <roycroft> that can mill yogurt
[23:11:20] <roycroft> it would probably get pretty smelly after a couple days
[23:18:43] <t12> can you build a mill out of dry ice
[23:18:47] <t12> that only cuts water ice
[23:27:43] <renesis> t12: yes.
[23:27:52] <renesis> they already do this is northern europe
[23:31:51] <t12> how much worse are shars graded gauge block sets going to be
[23:31:52] <t12> vs brand name
[23:31:55] <t12> estimate
[23:33:08] <t12> (gage)
