[00:06:01] <dirty_d> why wouldnt the manufactureer just do that?
[00:06:01] <_methods> do what?
[00:08:08] <dirty_d> specify the diameter as it would be if the points were infinitely sharp
[00:08:08] <dirty_d> they designed it, so they do know that dimension
[00:08:09] <_methods> well personally i'll look at the manufacturers sheets but in the end i'm making the part so i measure the tools i'm working with
[00:08:09] <_methods> i trust nothing
[00:08:09] <_methods> great way to scrap parts just going by a piece of paper

[00:11:09] <dirty_d> _methods, how do you measure it? micrometer and some kinda 60deg thing that mates against the cutters?
[00:11:24] <Tom_itx> no, round bars
[00:11:32] <_methods> the threads?
[00:11:37] <Tom_itx> yes
[00:11:44] <dirty_d> i mean on the thread mill
[00:11:45] <Tom_itx> there should be data for that
[00:11:46] <_methods> yeah either thread mic or 3 wire
[00:11:47] <dirty_d> single profile type
[00:12:00] <_methods> well for that cutter i'd put it in a vblock
[00:12:29] <dirty_d> thats 90 deg though
[00:12:36] <_methods> measure cutter round diameter then drop down to centeline
[00:12:52] <_methods> then rotate the cutter to hit the high
[00:12:59] <_methods> to measure it's dist from centerline

http://www.model-engineer.co.uk/sites/7/images/member_albums/70420/439869.jpg
[00:15:17] <Tom_itx> get the profile data on the cutter for the tip radius then calculate the difference
[00:15:17] <dirty_d> i think i could just get away with pretending it is infinitely sharp
[00:15:20] <_methods> yeah
[00:15:20] <dirty_d> cut the OD, then cut the ID a little small then finish to fit
[00:15:26] <dirty_d> and record what offsets i needed

[00:17:55] <_methods> weird thread or something?
[00:17:55] <dirty_d> yea
[00:17:56] <dirty_d> plus i figured i can do any kinda thread within a pretty braod range with just a few of these
[00:17:56] <dirty_d> sure its slower, but i dont care
[00:17:56] <_methods> yeah
[00:17:56] <_methods> its' handy for small runs
[00:17:56] <dirty_d> not building a factory or anything
[00:17:56] <_methods> and odd threads
[00:17:56] <dirty_d> just hobby stuff
[00:17:56] <_methods> yeah
[00:17:56] <_methods> it works just sneak up on it
[00:17:56] <_methods> and you'll be good to go
[00:17:56] <dirty_d> im learning theres a lot of that in this
[00:17:56] <dirty_d> a lot more manual that i thought
[00:17:56] <_methods> yeah there are a lot of variables
[00:18:04] <_methods> best to be patient
[00:18:15] <_methods> it's either that or you get to make the part again lol
[00:18:24] <dirty_d> like for holes and ODs ill just using a boring bar and creep up to what i need
[00:18:31] <_methods> yeah
[00:18:43] <dirty_d> im kinda worried about the boring head screwing off coing CCW though
[00:18:47] <dirty_d> i think it just screws on
[00:18:59] <dirty_d> boring head i mean
[00:19:01] <dirty_d> no lathe
[00:19:17] <_methods> you're using a boring head on a cnc?
[00:19:17] <dirty_d> yea
[00:19:17] <_methods> why not just interpolate?
[00:19:30] <dirty_d> oh i do, i only use that if the diameter is important
[00:19:35] <_methods> ahhh
[00:19:36] <dirty_d> like for a bearing to fit
[00:19:40] <_methods> k
[00:20:00] <dirty_d> and probably the ID and OD that need to be thread milled
[00:20:01] <_methods> yeah i only use boring head in cnc for super tight stuff
[00:20:16] <dirty_d> but im not sure if even that is neccessary
[00:20:25] <dirty_d> the tolerances on threads looks pretty loose
[00:20:33] <_methods> yeah
[00:20:43] <_methods> well it depends on the thread call out
[00:20:47] <_methods> some can be very tight
[00:20:58] <_methods> but for the most part threads aren't too bad
[00:21:18] <dirty_d> i was looking at this for 3A and 3B
http://theoreticalmachinist.com/Threads_UnifiedImperial.aspx
[00:22:01] <dirty_d> looks like +/-0.003" for pitch diameter
[00:22:01] <_methods> yeah that shows you how to measure using 3 wire technique
[00:23:16] <_methods> do you have a machinists handbook?
[00:23:20] <dirty_d> nope
[00:23:27] <dirty_d> im not sure which of those numbers is ideal either
[00:23:38] <dirty_d> like for major diameter 0.7500 / 0.7428
[00:23:53] <_methods> well it's pretty handy for that stuff
[00:23:57] <dirty_d> 0.75 would seem to be idea for a 3/4" thread
[00:24:00] <_methods> and explains a lot of things in more depth
[00:24:13] <roycroft> dirty_d: you really should get a copy of machinist's handbook
[00:24:20] <roycroft> and the book does not increase in size
[00:24:31] <_methods> your brain might though lol
[00:24:36] <roycroft> because it needs to fit in the drawer of a kennedy machinist's tool chest
[00:24:48] <dirty_d> lol
[00:24:50] <roycroft> so modern versions which have a lot of cnc info dropped some of the old-timey stuff
[00:25:07] <dirty_d> is that the name of an actual book?
[00:25:12] <roycroft> i say this because i'm going to recommend you go on ebay or amazon and get an old copy, from the '40s or the '50s
[00:25:13] <dirty_d> or a variety
[00:25:17] <roycroft> you can get it really cheap
[00:25:19] <_methods> machinery's handbook
[00:25:25] <roycroft> and yes, machinery's handbook
[00:25:25] <dirty_d> ahh, i see that
[00:25:35] <roycroft> and you can get a current copy later on
[00:25:37] <roycroft> if you want
[00:25:40] <roycroft> it's about $80
[00:25:53] <tjtr33> actual book, and machinists toolcases had a special drawer for it, true, and it was that basic a tool, that you really needed
[00:25:53] <roycroft> but you can an old copy for a fraction of that amount
[00:26:05] <_methods> i'm sure you can find a digital one for nothing
[00:26:07] <roycroft> yes, and they really did design a special drawer for it
[00:26:10] <tjtr33> cd available
[00:26:12] <dirty_d> yea id imagine
[00:26:15] <roycroft> and it really doesn't get bigger because of that
[00:26:26] <dirty_d> hah
[00:26:30] <_methods> but it's nice having it there physically
[00:26:37] <roycroft> the wooden gerstner machinist's chests have the drawer too
[00:26:52] <roycroft> it's good having a physical copy when you're working in the shop and need to look something up
[00:26:52] <tjtr33> thin bible paper, tiny fonts, a zillion pages
[00:27:27] <dirty_d> but for all intents and purposes, the pitch diameter is whats really important, because of varying radiuses?
[00:27:43] <_methods> the pitch diameter is what matters
[00:28:08] <dirty_d> but then how do they specify the pitch diameter for say a 3/4" UNF thread?
[00:28:32] <dirty_d> is it the centerline between an imaginary perfectly sharp thread with a 3/4" major diameter?
[00:28:40] <dirty_d> or 3/4" to the rounded edge?

[00:29:34] <_methods> http://www.efunda.com/designstandards/screws/unified.cfm?start=148&finish=227

[00:31:29] <_methods> that's max and min pitch

[03:37:02] <furrywolf> a vmc, enough money to get tooling for it, a house to put it in, a mature, intelligent, sane, good-with-a-strapon woman who knows cad/cam to use it with,...
[03:37:16] <alex4nder> don't get crazy
[03:38:50] <alex4nder> https://www.youtube.com/watch?v=3Ri5CQ5cIj8 <- that's pretty hilarious
[03:39:09] <zeeshan> what in the
[03:39:10] <zeeshan> f
[03:39:20] <zeeshan> thats a serious lathe
[03:39:34] <alex4nder> frankentaig
[03:41:12] <furrywolf> heh, that's a good idea. I could make my shoptask do that remarkably easily.
[03:41:47] <furrywolf> given as I have a 4" rotary table and an angle plate for it... lol
[03:42:59] <zeeshan> i just want a damn lathe
[03:43:02] <alex4nder> I'm wondering why they didn't use a standard spindle, and mount it back farther..
[03:43:04] <zeeshan> that works !
[03:43:48] <furrywolf> I'd guess the height of the rotary table, with space to clear tools, was higher than centerline...
[03:44:11] <alex4nder> furrywolf: I mean the one with the chuck attached
[03:44:21] <alex4nder> it's not a normal taig spindle...

[03:49:49] <alex4nder> yah jeez
[03:49:54] <alex4nder> that's basically free
[03:50:22] <furrywolf> it's an auction with three days left. the current price is not necessarily the selling price.
[03:50:30] <zeeshan> itll prolly sell for 3k
[03:50:34] <zeeshan> still good for that type of lathe
[03:50:43] <alex4nder> furrywolf: where could it go from there, that isn't 'free'
[03:50:58] <alex4nder> it's like scrap prices
[03:51:19] <furrywolf> it could well be scrap price. scrapyards often bid on equipment to crush...
[03:52:10] <zeeshan> well
[03:52:20] <zeeshan> its getting close to its scrap value
[03:52:23] <zeeshan> of $1475 :P
[03:52:32] <zeeshan> prolly actually past it
[03:52:36] <zeeshan> since someone would have to haul it
[03:53:43] <zeeshan> im hoping to work somewhere

[03:53:53] <zeeshan> and ill be like FU

[04:00:40] <furrywolf> we have something like fifty hydroponics stores, however.

[12:55:15] <TekniQue> translation: plz don't e-mail me, Linus
[12:55:29] <_methods> heheh
[12:55:34] <TekniQue> because Linus Torvalds is source of 100% of the abuse on the kernel mailing lists
[12:55:49] <_methods> that's why i thought it was especially entertaining
[12:56:04] <_methods> he's bred that into the system
[12:56:13] <TekniQue> Mauro, SHUT THE FUCK UP
[12:56:33] <TekniQue> my all time favorite kernel mailing list e-mail
[12:57:00] <_methods> well it covers all the bases
[12:57:10] <_methods> clear, concise, and to the point lol
[12:57:44] <CaptHindsight> I figured that some that cared would write a filter to catch "bad" words and replace them with terms like "doody head"
[12:58:18] <TekniQue> in the case of Mauro, I agree with Linus
[12:58:30] <TekniQue> Mauro committed something that broke a lot of user space code
[12:58:51] <TekniQue> and Mauro defended it saying that the interface was never documented to behave the way it did
[12:59:48] <CaptHindsight> thats the other problem, getting through to some people with the fewest number of words that have disabilities that limit their ability to pick up on subtleties
[13:00:49] <TekniQue> true
[13:00:50] <CaptHindsight> or people that just intentionally ignore everyone else until the terminology escalates to this level
[13:01:32] <malcom2073> The problem is, the loss of civility is due to the loss of sophistication.
[13:02:10] <malcom2073> Plus, the general air of elitism present in some open source project management.
[13:03:29] <CaptHindsight> it's the herd mentality that creeps in, some people just decide to vent since everyone else is doing it even though they do know better (Linus)
[13:10:20] <CaptHindsight> everyone else is doing it is the excuse for less than best efforts from many professionals, best effort what's that?
[13:10:20] <_methods> i like to call it trickle down douche-enomics
[13:10:20] <_methods> when the guy at the top is being a douche it just trickles down lol

[15:18:26] <_methods> ah sweet
[15:18:30] <_methods> did you try the borax?
[15:18:35] <_methods> i got the fire bricks
[15:18:35] <ssi> haven't gotten any yet
[15:18:43] <_methods> i have borax at the house
[15:18:57] <_methods> i was busy cleaning my free surface plate last night lol
[15:19:09] <ssi> I threw four 1" long chunks of 20mm tslot extrusion in there and heated them
[15:19:19] <ssi> they collapsed but it didn't really look like they'd liquified
[15:19:22] <ssi> threw a bunch of chips on top
[15:19:32] <ssi> then I started stirring and realized that there was just a solid layer of crud on top
[15:19:36] <ssi> but underneath it was liquid
[15:19:36] <_methods> so 80amps isn't quite enough?
[15:19:42] <_methods> ahh
[15:19:51] <DaViruz> you need magnetic stirring
[15:19:59] <DaViruz> though i don't know if that works with aluminium
[15:20:14] <ssi> I'm thinking flux will make the crud dissolve and flow out easier
[15:20:17] <ssi> and be easier to skim
[15:20:27] <ssi> 80A works good but it's hard to keep a consistent arc
[15:20:40] <_methods> might have to make a cnc feeder
[15:20:47] <DaViruz> you have some sort of height control?
[15:20:51] <DaViruz> automatic
[15:20:52] <_methods> feed the electrodes into each other

[15:22:35] <ssi> https://pbs.twimg.com/media/B_04Ph7XEAIN8Rr.jpg:large
[15:22:43] <ssi> flew tight formation like that for 350 miles yesterday
[15:22:50] <ssi> shit takes a LOT of concentration and fine motor control
[15:23:02] <ssi> and the RV I was in is extremely sensitive in pitch
[15:23:04] <_methods> i bet
[15:23:06] <DaViruz> i wonder if you get some free magnetic stirring from a three phase arc furnace
[15:23:15] <ssi> so it's laying my arm on my leg, holding the stick with thumb and forefinger
[15:23:17] <_methods> all that space up there and you want to fly right next to each other.........
[15:23:22] <ssi> the EFIS has a rate of change of airspeed indicator
[15:23:31] <ssi> and I basically fly that to null any change in airspeed for fine pitch control
[15:23:36] <ssi> trying to maintain +/- 1kt
[15:23:37] <ssi> it's HARD
[15:23:58] <ssi> a little bit of pitch up and I'm slowing down, and he has to throttle back to hold me... then on the corresponding pitch down, I'd run away from him

[16:00:27] <Cromaglious> true.. until I get another power supply... and or PWM spindle control board...
[16:05:42] <Rab> MeanWell, the Brand You Trust.
[16:07:14] <archivist> to fry
[16:07:36] <Cromaglious> looking at the schematic diagram... I'm burning the 100ohm resister going through the EL817 opticoupler which gets it power from the voltage drop across the R3 and R4 1ohm 2w resisters off the mosfett on the negative side of the spindle
[16:08:15] <archivist> 1 ohm and opto in the same sentence ?
[16:08:25] <Cromaglious> so a voltage drop across .5 ohm that's enough to fry a 1/4w 100ohm resister
[16:08:43] <Cromaglious> I was reading 57v last night

[17:37:04] <CaptHindsight> it must, it's the same ARM SOC

[17:38:30] <pcw_home> probably just a matter of setting up the pinouts
[17:39:29] <malcom2073> Nice
[17:40:05] <malcom2073> Nice, and fairly inexpensive.
[17:40:34] <CaptHindsight> I figured that someone would do this with one of the more recent TI SOC's with the PRU
[17:41:06] <malcom2073> I wonder if their stuff will be open source, I'd be interested in giving it a shot on the BBB
[17:41:30] <CaptHindsight> it doesn't look like it
[17:41:54] <ssi> I wouldn't mind trying that
[17:41:55] <CaptHindsight> http://linuxgizmos.com/sitara-am437x-dev-kit-targets-linux-based-industrial-apps/ this new Sitara also has a fast GPU
[17:42:03] <ssi> but I don't want to send them money and then wait and hope to receive something
[17:42:06] <malcom2073> It's open hardware, doesn't mention open software
[17:42:23] <CaptHindsight> are the schematics up somewhere?
[17:42:38] <malcom2073> "soon"
[17:42:48] <malcom2073> So it *may* be open hardware heh

[17:46:19] <ssi> if the 43xx series is as good as the 33xx but with enough gpu power to run axis well, I think it'd be a winner
[17:46:49] <CaptHindsight> I'd only make it an SOC with a GPU fast enough to support a decent display size and frame rate
[17:46:50] <malcom2073> Thats the big thing that kills the BBB with machienkit, it can't run axis well

[17:47:33] <ssi> I personally don't care about the pru stepgens, etc

[18:36:59] <CaptHindsight> ssi: thats what I'm asking
[18:37:19] <ssi> I'd lean toward the 26 pin superport headers
[18:37:43] <ssi> basically like a singleboard computer with integrated 6i25
[18:38:41] <CaptHindsight> yeah, you want both the header for internal wiring and the external conn
[18:39:02] <ssi> the board doesn't necessarily need to carry the DB25
[18:39:39] <ssi> the hm2 firmware provides for two ports; 5i25 has one exposed as a DB25 and one as an IDC26
[18:39:47] <ssi> your board could just have two IDC26 and that would be fine
[18:39:49] <CaptHindsight> true, would be more flexible if there are no external connectors

[18:42:14] <ssi> if you can pin it the same as the 6i25 then the hm2 firmwares should be compatible

[19:07:00] <Cromaglious> to travel one inch, I don't think it takes 4K revolutions, maybe 4K steps cuz that's like 0.00025" per rev of the motor, with 4K steps on a 200 step motor thats like 0.050" per rev

[19:12:52] <Cromaglious> so you're running 1 motor rev per 10 gear revs?
[19:14:30] <ssi> probably the other way around
[19:14:36] <Cromaglious> 8458.2 counts per inch
[19:14:36] <ssi> since servos are generally very fast
[19:14:49] <Cromaglious> <anonimasu> (I have torque) but not enough counts/rev) for direct drive

[19:16:23] <ssi> if you do integral stepper drivers, what are you going to use for step generation?
[19:16:33] <ssi> does imx6 have something pru-like?
[19:17:03] <ssi> oh does that chip do its own step gen somehow?

[19:20:10] <CaptHindsight> http://www.st.com/web/en/catalog/sense_power/FM142/CL851/SC1794
[19:20:53] <CaptHindsight> 2.5A stepper drivers are ok for tiny things like repraps
[19:21:05] <ssi> they're touting position mode control
[19:21:10] <ssi> but it's hard to tell if it's realtime capable
[19:21:16] <ssi> that's the mess I got into with those damn parker servo drives
[19:21:26] <ssi> they could ONLY be controlled via serial position commands
[19:21:26] <CaptHindsight> but 6A drivers on board could be useful for small mills
[19:21:34] <ssi> and there was no way to do realtime position control for closed loop
[19:21:58] <CaptHindsight> yeah, the others in that series don't have the controller
[19:22:02] <ssi> I wouldn't bother doing integral stepper drivers if you don't have a good way to do hardware stepgen
[19:22:19] <CaptHindsight> thats what the FPGA is for
[19:22:26] <ssi> yeah I suppose that's true
[19:22:45] <ssi> but wouldn't it make more sense to just make a daughterboard for the IDC header which has stepper drivers on it?
[19:22:53] <ssi> 7i76 but with integral drivers?
[19:23:33] <ssi> there's gonna be a lot of power design considerations for the stepper drivers
[19:23:41] <ssi> a lot of complexity for a non-pop option on the sbc
[19:23:51] <CaptHindsight> difficult if you're new to it
[19:24:16] <ssi> I mean we could make that board as another product
[19:24:24] <CaptHindsight> also the target application for the board
[19:25:01] <CaptHindsight> hobbyist 3d printers with 2A stepper drivers like the one on kickstarter
[19:25:02] * anonimasu nods
[19:25:12] <anonimasu> so how fast do you set the accel for 0.5g?
[19:25:17] <ssi> there's already dozens of those out there
[19:25:37] <CaptHindsight> but none with a GPU for a GUI
[19:26:01] <ssi> I just feel like if you design around the stepper drivers, you're baking in a lot of inflexibility
[19:26:16] <ssi> if you design around something like superport, then a separate board can be your driver/breakout
[19:26:18] <PCW> all the smarts in that chip just make coordinated motion harder

[19:26:54] <CaptHindsight> I didn't see the comntroller in there

[19:27:13] <CaptHindsight> the others are just step and dir

[19:29:23] <CaptHindsight> a daughter card with all the drivers is simple as well

[19:30:44] <ssi> PCW: what I'd like to do is get the pinout of the s6lx9 on the SBC exactly the same as the pinout of the 6i25, so that hm2 firmwares work unchanged
[19:31:07] <_methods> make the drivers socketed so you can remove them
[19:31:29] <ssi> _methods: if the drivers are on a daughterboard, it'd just be a single 26 pin ribbon cable

[19:57:07] <PetefromTn_> that is actually NOT the largest gator I ever saw down there tho...
[19:57:54] <LeelooMinai> And who said golf is not an extreme sport
[19:58:31] <LeelooMinai> I bet some Japanese would pay a lot of money to play on that golf course:)
[19:58:35] <PetefromTn_> When I was growing up we lived in Wellington and they had a series of lakes throuought the area with Golf Courses on there. They once pulled a gator out of there that barely fit in the back of a fullsize pickup truck width wise.... IT was a real monster.
[19:59:20] <furrywolf> no gators here. bears and bobcats, however.

[20:00:39] <furrywolf> bears don't tend to show up here too often, but they do show up from time to time... once one got in my garbage and bit clean through a steel can.
[20:00:44] <_methods> they just started letting people hunt for them again around here
[20:01:08] <CaptHindsight> golfers?
[20:01:12] <_methods> hahah
[20:01:17] <_methods> they've always been open season
[20:01:53] <PetefromTn_> I LOVE me some Gator Tail snacks it is DELICIOUS!!
[20:01:55] <Cromaglious> ones in the short skirts tend to be more tender and juicier
[20:02:53] <PetefromTn_> that is a bigass gator tho they photographed yesterday.... Would not want to be looking for my ball near the water traps over there LOL. I enjoyed the chubbs comment Hehehe

[22:39:58] <anonimasu> i just didnt get if that's in the "units" like mm or the encoder counts
[22:40:08] <Bushman> goes to Z5 and then back to Z0
[22:40:11] <ssi> units is mm or inch
[22:40:26] <anonimasu> heh.. that was easy.
[22:40:27] <Bushman> and THEN it goes back up to tool change position
[22:40:31] <Bushman> what's happening?
[22:40:36] <Cromaglious> it's the setting.. G20 is a inch file, G21 is a metric file
[22:40:40] <PCW> yes accel is in machine units per second squared
[22:40:51] <anonimasu> let me throw my rail axis into the wall.
[22:40:54] <anonimasu> brb.
[22:41:04] <PCW> just like velocity is in machine units per second

[22:56:57] <Cromaglious> looking I was thinking Mach3 not linuxcnc
[22:59:01] <Cromaglious> TOOL_CHANGE_POSITION = 0 0 2 - Specifies the XYZ location to move to when performing a tool change if three digits are used. Specifies the XYZABC location when 6 digits are used. S
[22:59:13] <Cromaglious> that's in the ini file
[22:59:31] <Cromaglious> TOOL_CHANGE_QUILL_UP = 1 - The Z axis will be moved to machine zero prior to the tool change when the value is 1. This is the same as issuing a G0 G53 Z0.
[23:00:18] <Cromaglious> they're from this file

[23:00:26] <Bushman> oh
[23:00:56] <Bushman> quill up? what does it mean?

[23:01:17] <PCW> dangerous porcupine?
[23:01:20] <Bushman> my tool is already above the surface... bringing it to machine 0 will cause it colide
[23:01:29] <Cromaglious> quill == Z
[23:01:49] amnesic is now known as amnesic_away
[23:02:00] <Cromaglious> so use = 0 on that config if you have it in your ini file
[23:02:30] <Bushman> then it will do linear move from where it is. right?
[23:02:40] <Cromaglious> My Z 0 is at top, and all Z moves are to negative numbers
[23:03:22] <Bushman> my z is not on top :(
[23:03:29] <Bushman> Z0
