[00:00:04] <Tom_itx> it's a creature comfort
[00:02:00] <Tom_itx> i should sit down and learn macros i suppose
[00:02:07] <Tom_itx> and subroutines
[00:02:39] <Tom_itx> that's the bad thing about cad cam
[00:02:43] <Tom_itx> it makes you lazy
[00:03:05] <andypugh> I normally write the G-code by hand.

[00:03:21] <Tom_itx> i did alot of 3d parts that couldn't be hand written
[00:03:34] <Tom_itx> lofted contoured stuff
[00:03:50] <andypugh> I am sure they could, it would just be immensely difficult and tedious.
[00:04:00] <Tom_itx> not cost effective

[00:06:57] <andypugh> My enthusiasm for going out to the garage for some midnight milling waned when I remembered I would need to clock up to the fixture.

[00:11:08] <Jymmm> Man, I go thru dvd drives like toilet paper
[00:11:09] <Tom_itx> are they hard to machine?
[00:11:18] <andypugh> I don't know yet :-)
[00:11:19] <Tom_itx> Jymmm got the runs?
[00:11:36] <Tom_itx> Jymmm, save em and make eeprom burners
[00:11:42] <Jymmm> Tom_itx: No, but they dont last me more than 9months
[00:11:53] <Tom_itx> andypugh, i noticed you talking about cutters earlier
[00:12:02] <Jymmm> Tom_itx: burners?
[00:12:09] <Tom_itx> yes
[00:12:10] <andypugh> The first attempt failed when the shape came free of the material before all the slots were machined (which is likely to always be a problem.

[01:08:26] <Jymmm> Is there such a thing as "Titanium plated" ?
[01:09:41] <elmo40> sure there is.
[01:09:52] <elmo40> you can plate any metal to any metal (pretty much)
[01:10:15] <elmo40> take a look http://www.titaniumexclusive.com/
[01:10:27] <elmo40> expensive! $300 for a 9" fry pan
[01:10:28] <Jymmm> I figured that, but I've never heard of something "titanium plated" before, just solid titanium.
[01:11:02] <Jymmm> For $300, it better be solid titanium.

[01:15:00] <Jymmm> Heh, wanna bet?
[01:15:16] <elmo40> I was in the mall when the guy poured sugar onto it. the sugar melted, then turned brown. didn't stick. didn't even burn! just stayed liquid.
[01:15:52] <elmo40> put cheese on it. grated. it melted, didn't stick. left it there for 4 min, didn't burn, didn't stick
[01:16:08] <Jymmm> I do that in my cast iron pan all the time.
[01:17:03] <Jymmm> Makes great grilled cheese that way
[01:17:12] <A2Sheds> it didn't burn since the pan wasn't hot enough
[01:18:00] <Valen> we have cast iorn pan for all our frying, stainless for general cooking, and 2x non stick for stuff like eggs
[01:18:14] <Valen> pancakes work well in the cast iron
[01:22:16] <jy76> first time here does this work?
[01:22:44] <mozmck> we do eggs in a cast iron pan without sticking. you just have to have it seasoned right.
[01:23:14] <mozmck> a little bacon grease helps too.

[07:47:49] <Turtl3boi> how much does it cost to make one of these buggers Jymmm?
[07:48:16] <anonimasu> what kind of sheet are you going to cut?
[07:49:44] <Turtl3boi> super thin stainless steel
[07:49:58] <Turtl3boi> 1mm or less
[07:50:46] <Turtl3boi> i don't think a plasma cutter will produce nice clean cuts for what i want to do so that's why i was thinking of laser
[07:54:38] <Turtl3boi> anonimasu, any ideas? any experience you can share?
[07:55:09] <anonimasu> if you buy plasma buy one known to work, i had hell with mine enough to use oxyfuel for cutting instead
[07:55:16] <anonimasu> (hf noise)
[07:56:31] <Turtl3boi> does that produce clean results though?
[07:56:45] <Turtl3boi> i mean i want to make something fairly smallish
[07:57:06] <anonimasu> it does in thin stuff
[07:57:08] <Turtl3boi> let's say, it's for instance, a coffee mug made of stainless steel
[07:57:24] <Turtl3boi> can i produce the clean cuts necessary to make a cylinder rolled-up
[07:57:36] <Turtl3boi> and would the edges be really rough after plasma cutting?
[07:58:04] <anonimasu> at that thin sheet it really wont make a big difference
[07:58:13] <anonimasu> hwo0ever you will have edge discoloration in stainless from the heat
[07:59:07] <anonimasu> most likely
[07:59:44] <Turtl3boi> hmmmm
[08:00:10] <Turtl3boi> how is stainless steel sheet usually cut for kitchen ware purposes?
[08:00:20] <Turtl3boi> so that it doesn't have that discoloration
[08:00:57] <Turtl3boi> do you have knowledge of production of stainless sheetmetal for kitchen products
[08:10:37] -!- e-ndy [e-ndy!jkastner@nat/redhat/x-rjncakemqjdsxjvs] has joined #emc
[08:11:06] <Loetmichel> mornin'
[08:12:11] <Loetmichel> Turtl3boi: you can polish the discoleration off afterwards
[08:12:20] <Turtl3boi> hey Dr. B
[08:12:35] <Turtl3boi> what's the best way to cut stainless steel if i want really accurate cuts
[08:12:40] <Turtl3boi> for say, making a coffee mug
[08:16:42] <Loetmichel> CNC mill
[08:16:44] <Loetmichel> ;-)
[08:17:24] <Loetmichel> sheet metal "scissors"
[08:17:28] <Turtl3boi> really?
[08:17:35] <Turtl3boi> better than laser cutter?
[08:17:47] <Loetmichel> yes and no
[08:18:01] <Turtl3boi> do i need a super fast spindle speed to cut sheet
[08:18:13] <Loetmichel> a laser cutter discolors the edges and CAN have some drebris on the cutting edge
[08:18:47] <Loetmichel> and for the thermal stress warping of the sheet CAN occur
[08:19:22] <Loetmichel> but a mill which cuts stainless has to be relatively sturdy adn have a FAST spindle
[08:19:32] <Turtl3boi> how fast?
[08:19:36] <Turtl3boi> 5000rpm?
[08:19:41] <Turtl3boi> 10,000rpm?
[08:19:52] <Loetmichel> depending on the diamaeter of the mill bit
[08:20:31] <Loetmichel> i have milled normal steeel with 0,8mm tungsten carbide bits at about 30kRPM
[08:21:21] <archivist> Turtl3boi, photo etch, punch, water jet
[08:21:23] <Turtl3boi> with your mini mill homemade
[08:21:45] <Turtl3boi> ahh yes but i'm looking to make something like a coffee mug and not have to do much post processing
[08:21:46] <Loetmichel> yes
[08:21:50] <Turtl3boi> i want it to be "food grade"
[08:22:14] <Turtl3boi> and i want the edges to be smooth (so it doesn't rip at someone's lips when they take a sip)
[08:22:17] <archivist> cnc water jet would be reasonable after the cutting
[08:22:30] <Turtl3boi> and of course it can't be discolored and i don't want to have to resort to nasty chemical baths to remove discoloring
[08:22:45] <archivist> but edges will need finishing on any method
[08:22:47] <Loetmichel> hmm, a coffee mug should have a "rolled in" edge
[08:23:05] <Turtl3boi> ahhh ok.......
[08:23:09] <Loetmichel> that would require a pressing tool
[08:23:15] <Loetmichel> and a BIG press
[08:23:28] <archivist> you need to join for a cup so how?
[08:23:52] <archivist> or deep draw :)
[08:24:10] <Turtl3boi> joining would be done with brazing and spot-welding i'd assume
[08:24:22] <Loetmichel> archivist: one can do the mug out of one pieces of sheet metal... but that would require an even BIGGER press
[08:24:24] <Turtl3boi> i can silver braze stainless because silver is an acceptable food grade metal right?
[08:24:27] <Loetmichel> ;-)
[08:24:28] <archivist> brazing would be the wrong colour
[08:24:36] -!- packrat has quit [Ping timeout: 240 seconds]
[08:24:43] <Turtl3boi> ok then spot weld?
[08:24:59] -!- packrat [packrat!~packrator@c-98-209-146-133.hsd1.mi.comcast.net] has joined #emc
[08:25:09] <archivist> spot weld will leave cracks for dirt to live
[08:25:15] <Turtl3boi> ahh ok
[08:25:26] <archivist> laser weld the seam
[08:25:28] <Turtl3boi> then it hast to be a weld
[08:26:00] <archivist> metal is a bad idea for a mug
[08:26:20] <Turtl3boi> no this is just an example
[08:26:26] <Loetmichel> Turtl3boi: ANY means of connecting 2 parts of stainless will discoloir the material and/or have cracks for dirt to live in
[08:26:27] <Turtl3boi> i have something else in mind
[08:26:32] <anonimasu> as archivist said deep draw is a good idea but not cheap
[08:26:47] <Turtl3boi> aiya......
[08:26:59] <archivist> deep draw is the only seamless mug method
[08:27:08] <archivist> or cast!
[08:27:20] <Loetmichel> hrhr, stainless steel casting...
[08:27:41] <Loetmichel> and then heavy machining... a little bit much work for a mug ;-)
[08:27:53] <anonimasu> anyone know how i would add a sum to my requested position so i can override the height while running?
[08:28:06] <Turtl3boi> oh deep draw is basically a giant stamping process
[08:28:10] <anonimasu> yep
[08:28:34] <Turtl3boi> is that expensive
[08:29:09] <archivist> yes
[08:29:11] <anonimasu> es
[08:29:11] <Loetmichel> it is
[08:29:20] <archivist> capital cost is high
[08:29:25] -!- packrat has quit [Ping timeout: 240 seconds]
[08:29:49] <archivist> production is low cost, coke cans are made that way
[08:29:51] <Turtl3boi> eeeK
[08:30:28] <archivist> turn/mill from solid
[08:30:28] <anonimasu> also, it requires annealing material between operations
[08:30:40] <anonimasu> a forming operation?
[08:30:45] <anonimasu> (metal spinning)
[08:30:47] <Loetmichel> the machines are expensive but have a high throughput-> nothing for ONE piece, more like a million pieces
[08:31:18] <Turtl3boi> dangit this is hard
[08:31:39] <Loetmichel> metal spinning could do the trick but that has to be learned well, AND requires a sturdy lathe .
[08:31:55] <Loetmichel> and can make only rotational symetric parts
[08:31:58] <anonimasu> cnc metal spinning :p
[08:32:19] <anonimasu> cam follower and a assymetric plug ;)
[08:32:31] <Loetmichel> hrhr
[08:32:33] <anonimasu> dont say it's impossible :p
[08:32:36] <anonimasu> just not very fun
[08:32:57] <anonimasu> now how the hell do i fix my torch height on this machine -_-
[08:33:05] <anonimasu> (manual override)
[08:33:16] <Turtl3boi> torch height for what?
[08:33:21] <Loetmichel> i've seen a CNC machine with a "roller" pair above and below a sheet metals which cvan form nearly ANY part out of a sheet
[08:34:27] <archivist> there is one more method, hydraulic forming into a female mould
[08:34:31] <Turtl3boi> i want to make a cone section out of sheet
[08:34:32] <Loetmichel> like metals spinning but more like the car body shop rollers in function
[08:34:36] <Turtl3boi> conical section
[08:35:00] <Turtl3boi> like a dunce cap with the top shaved off to remove the point
[08:36:23] <Loetmichel> Turtl3boi : you COULD make a big mould from steel, place it with a stainless steel and some dynamite in a swimming pool lite the fuse and run ;-)
[08:36:35] <Turtl3boi> hahaha..

[08:37:19] <Loetmichel> dont laugh. there ARE companys which make complicated metal forms this way!
[08:39:06] <Loetmichel> google explosion forming
[08:39:12] <Turtl3boi> makes sense
[08:39:20] <Turtl3boi> but yeah i don't like loud noises ;)
[08:41:27] <Turtl3boi> well thanks again then, Soldering Michel
[08:41:32] <Turtl3boi> or Brazing Michel?
[08:48:31] <archivist> stainless is hard to solder/braze due to the chrome content
[08:48:33] <Loetmichel> soldering
[08:50:25] <Turtl3boi> so welding is the best bet
[08:50:31] <Turtl3boi> but that also causes discoloration
[08:50:44] <Turtl3boi> god what a pain why do people even make stuff out of stainless
[08:50:51] <Turtl3boi> not to mention chrome is not really good for you
[08:56:00] <Loetmichel> Turtl3boi: stainless isnt SO bad. try hardox if you want a PIA
[08:56:10] <Turtl3boi> hardox is what?
[08:56:12] <Loetmichel> to work with ;-)
[08:56:13] <Turtl3boi> PIA?
[08:56:14] <archivist> how many do you want to make
[08:56:18] <Turtl3boi> pain in ass?
[08:56:28] <Turtl3boi> i want to make 10,000
[08:56:35] <Turtl3boi> but they're not cups =p
[08:56:37] <Loetmichel> yes
[08:56:48] <archivist> use a subcontractor with the equipment
[08:57:12] <Loetmichel> hardox is a steel which work hardenes to the extend taht you cant drill it if you are to slow
[08:57:50] <Loetmichel> its used fpr lorries for example
[08:57:58] <Turtl3boi> oh this is for armor plating
[08:58:04] <Turtl3boi> FPR Lorries?
[08:58:13] <Turtl3boi> Lorries? what's that
[08:58:25] <Loetmichel> s/lorries/dumptrucks
[08:59:08] <Loetmichel> for the parts that come in contact with the stone
[08:59:52] <Turtl3boi> oh yeah the teeth on the shovel
[09:00:33] <Loetmichel> for example, yes
[09:00:59] <Loetmichel> THAT is a Pain inn the A***
[09:01:32] <Loetmichel> stainless is easy going compared to hardox ;-)
[09:02:43] <Turtl3boi> do you think it is practical to setup a sheetmetal manufacturing? or just have someone else do it
[09:03:17] <Loetmichel> let someone else do it
[09:03:55] <Loetmichel> for only 10000 parts it will not be cost effective to setup a sheet metal workshop
[09:04:44] <Turtl3boi> darnit
[09:04:50] <Turtl3boi> i thought it might be fun
[09:06:20] <archivist> I have made sheet metal parts but would subcontract the punching certainly
[09:07:05] <Turtl3boi> you can?
[09:07:09] <archivist> buying a second hand presses to do the forming is possible
[09:07:48] <Turtl3boi> even if i could get sheetmetal pieces cut for me, and did the forming myself, i would still need to find a way to do the joining

[09:08:35] <anonimasu> aah hardox :D
[09:08:39] <archivist> I use tinplate so I can solder
[09:08:45] <anonimasu> I cut 100 parts out of it yesterday
[09:09:18] <Turtl3boi> tinplate? solder? is that food grade?
[09:09:48] <archivist> tinplate is used for biscuit tins
[09:10:14] <archivist> solder is not food grade as I use good old 60:40
[09:11:18] <archivist> costing your press tooling is important
[09:12:22] <Turtl3boi> costing? what does costing mean?
[09:21:45] <archivist> working out the cost of tooling and production
[09:22:30] <Turtl3boi> of course
[09:22:33] * archivist is off to customer now, may reappear as herron
[09:22:39] <Turtl3boi> k g'nite
[09:22:50] <Turtl3boi> catch a fish, young herron
[09:22:57] <Turtl3boi> =p
[09:23:45] <Loetmichel> Turtl3boi: tin IS food grade, for all foods with no acid in it
[09:24:00] <Loetmichel> so no orange juice in a tin can ;-)
[09:24:07] <Turtl3boi> coffee is acidic
[09:24:11] <Turtl3boi> =p
[09:25:23] <Turtl3boi> coffee ist sauer, no?

[15:06:01] <pcw_home> Well you can use both (for example the second port on the 5I25 could be used for low voltage GPIO)
[15:06:02] <pcw_home> but normally with a 7I76 you would just use the 7I76s field I/O since its inputs are high voltage, filtered and protected
[15:06:04] <pcw_home> and the outputs will drive relays, 24V drive enables, solenoids etc
[15:06:05] <pcw_home> also any GPIO that routed to the 7I76 is going to be "special" like being encoder inputs, or RS-422 ports etc
[15:06:22] <pcw_home> GPIO thats
[15:06:27] -!- mhaberler has quit [Quit: mhaberler]
[15:16:51] <JT-Shop> so the I/O list that shows up for the 5i25 is the second port on the card?
[15:24:59] <pcw_home> Not entirely you will have some GPIO show up that go to the 7I76s RS-422 expansion port
[15:25:01] <pcw_home> (if its not used by a SSERIAL expansion card)
[15:25:03] <pcw_home> and the encoder port bits will be shown as GPIO if you dont enable the encoder
[15:25:04] <pcw_home> (and in fact will still be available as inputs even if you enable the encoder)
[15:32:22] <pcw_home> Its better not to use any GPIO bits connected to a daughtercard unless you know which direction they go, for example
[15:32:24] <pcw_home> if you have 7I76 connected to a 5I25, the if the encoder is disabled, the pins used for the encoder will show up as GPIO
[15:32:25] <pcw_home> but if you enable them as outputs they will confilct with the 7I76s encoder pins that drive the 5I25
[15:34:53] <JT-Shop> thanks Peter, I think I understand now
[15:37:02] <JT-Shop> I was trying to make sense of what Show Hal Configuration showed when I looked at it
[15:37:42] <pcw_home> so in fewer words you can use GPIO 17..33 but probably better not to use whichever of GPIO 0..16 show up
[15:39:22] <pcw_home> (since they all go to the 7I76 as there no are simple I/O bits brought out on the 7I76)
[15:41:25] <pcw_home> Note this is not always true, for example there a simple I/O protector for the 5I25 thats just like the 7i42
[15:41:27] <pcw_home> with this daughtercard you are free to use any pin as GPIO

[17:11:54] <tom3p> MattyMatt, wow!
[17:12:38] <MattyMatt> $68 board
[17:12:51] <MattyMatt> and I do like the web interface
[17:13:20] <MattyMatt> in theory it looks more pretty than useful atm :)
[17:14:19] <tom3p> yah, but very best of luck to them!
[17:16:03] <MattyMatt> is it true newegg don't have the $80 atom board anymore, and you need to spend $130 now?
[17:16:30] <MattyMatt> newegg never shipped to UK so it was always a theoretical price for me
[17:18:42] <pcw_home> d525 is $75
[17:18:46] <MattyMatt> I'd consider than miniemc2 in machines I was selling but I'd rather have a embedded PC for myself, just so I can ask in here how it works :)

[17:19:20] <tom3p> hehe i like the home icon, its just a std arrow with a block on it, makes a chimney on a house roof, clever
[17:20:01] <MattyMatt> and is the d525 better latency than the average PC, or do you need the d550 to hit the sweet spot?
[17:20:49] <pcw_home> D525 has good latency (the intel one)
[17:21:32] <MattyMatt> cool, so the miniemc2 isn't compelling purely on cost
[17:22:09] <MattyMatt> pretty interface tho :)
[17:22:23] <ssi> could be interesting to do something like an ipad pendant that controls it
[17:22:26] <tom3p> miniemc2 user manual is in russian Введение
[17:22:27] <pcw_home> Well the PC needs RAM and drives added
[17:23:26] <tom3p> oops begins russian, then becomes english
[17:24:05] <MattyMatt> spacemen need to be able to read russian :)
[17:24:18] <MattyMatt> and chinese soon
[17:24:22] <pcw_home> The thing i would worry about a little with an embedded ARM is the platform stability
[17:24:23] <pcw_home> (cell phone chips change every 6 Months its seems and the take the I/O with them)
[17:24:59] <MattyMatt> yeah that's my worry, they've adapted all the RT stuff to the hardware on that particular board
[17:25:54] <pcw_home> Cheesy though it may be the X86 pc is pretty stable
[17:25:58] <MattyMatt> so it's not a general arm solution

[17:27:47] <pcw_home> looks like a pretty nice fanless motherboard, wonder how it fairs latency wise

[18:14:48] <MattyMatt> just like momma's cats, except I got to keep my bollocks
[18:15:03] <Jymmm> you sure?
[18:15:08] * MattyMatt checks
[18:15:18] * Jymmm steps back
[18:15:31] <MattyMatt> yep, they are still in the jar on her shelf
[18:15:36] <Jymmm> HAHAHAHAHA
[18:19:42] <Jymmm> A2Sheds: Ok, I'm dumb here... I can grab a debian iso and have it boot up on the beaglebone and access it via ethernet (or whatever) ?
[18:20:17] <Jymmm> A2Sheds: or do I have to create a custom debian build?
[18:21:54] <IchGucksLive> Airfoils all over -> list http://www.ae.illinois.edu/m-selig/ads/coord_database.html
[18:22:58] <pcw_home> A2Sheds: those encoders have very weak pullups maybe you need to add a stiff pullup
[18:23:03] <A2Sheds> Jymmm: the beaglebone ships a day now and yes there will be images you can just download that work
[18:23:38] <Jymmm> A2Sheds: Ok, so I CANT use emc ubuntu iso, but has to be a special one
[18:23:56] <pcw_home> especially if you are driving an opto at the same time or is this the same setup?
[18:23:58] <A2Sheds> http://beagleboard.org/project/ubuntu/ for instance here is the image for the beagleboard
[18:24:30] <Jymmm> A2Sheds: Ah, ARM Ubuntu, like sparc, etc
[18:24:33] * FinboySlick has a beagleboard but never actually had time to get it to boot.
[18:24:35] <A2Sheds> Jymmm: no , it has to be Ubuntu, debian, angstrom just for ARM

[18:26:14] <A2Sheds> there is also a dual arm cortex a9 pandaboard http://pandaboard.org/
[18:27:02] <Jymmm> darnit, I wish they gave the detailed specs (like gpio qty etc)
[18:27:07] <A2Sheds> but you can't buy parts at quan <100K and they are $149 for the board (that is only made in batches of 100 pcs/mo)
[18:27:44] <A2Sheds> Jymmm: http://beagleboard.org/static/BONESRM_latest.pdf
[18:28:33] <Jymmm> 65
[18:29:02] <Jymmm> They say 3 serial ports. is that TTL or RS-232?
[18:29:07] <A2Sheds> plus 8 PWM outputs, not sure of the range or speed yet
[18:29:51] <FinboySlick> Jymmm: Pretty sure you have one rs232 on the pandaboard, the other are probably ttl.
[18:31:12] <A2Sheds> looks right for the Pandaboard, i have one sitting next to me but not under power
[18:31:37] <Jymmm> There are five serial ports on the expansion headers. UART1-4 has TX,Rx,RTS and CTS
[18:31:37] <Jymmm> signals while UART5 only has TX and RX.
[18:32:32] <tom3p> the hal2dotty can autogen the net names too ( i need some CSS here :/ http://imagebin.org/185631
[18:32:46] <A2Sheds> http://www.ti.com/lit/gpn/am3359 datasheet for the beaglebone cpu am3359
[18:33:44] <A2Sheds> it would be slick if the arm soc could drive servos from the PWM outputs
[18:33:59] <Jymmm> A2Sheds: Thats strange as it say gigabit, but beaglebone says 10./100
[18:35:35] <A2Sheds> the mac is 10/100/1000 but maybe the beaglebode only uses a 10/100 phy?
[18:35:55] <Jymmm> A2Sheds: I guess they just went cheap
[18:36:35] <Jymmm> dual gigabit at that
[18:37:21] <pcw_home> Power too 1gbit phys are power hungry
[18:37:54] <A2Sheds> lots of 16bit PWM outputs, not sure if the speeds yet TBD
[18:38:00] <pcw_home> probably not too good for servos unless it can count encoders
[18:39:37] <pcw_home> A2Sheds did you see HEDS 5500 TTL high spec is at -40 uA?
[18:40:02] <Jymmm> A2Sheds: populate with a JTAG chip, and sounds like you can connect to literally anything.
[18:40:25] <Jymmm> except rs-232 and paraport
[18:40:41] <Jymmm> wait, I take back the paraport
[18:41:27] <A2Sheds> well, these are early specs and TI has decided to not fix some parts in the past
[18:42:11] <Jymmm> A2Sheds: But have they included the broken parts of the past into this?
[18:42:30] <A2Sheds> have to wait and see
[18:42:36] <Jymmm> heh, ok
[18:44:49] <Jymmm> the video below the girl is pretty good http://beagleboard.org/bone
[18:44:52] <A2Sheds> pcw_home: whats the input load on the 7i33 again?
[18:45:42] <pcw_home> its a CMOS Schmitt trigger but has no pullup
[18:46:29] <Jymmm> Cloud9 ***JAVASCRIPT*** ?!?!?!?! (no shit?)
[18:47:04] <A2Sheds> figures, encoder side of servo shaft 1/4 inch, my rotary encoder is 10mm
[18:47:13] <pcw_home> So if you are driving and OPTO at the same time it should have its anode to 5V (so it helps pullup)
[18:47:54] <pcw_home> since the encoder will not source much current

[18:50:22] <pcw_home> stand on your head
[18:51:06] <A2Sheds> parker has these nice integrated encoder in their servos, but i can't find replacements for just the encoder
[18:53:08] <Jymmm> I thought this was cool.... There are pads on the bottom to solder-on a JTAG header. You'll need to remove a few small resistors as well. The trade-off was made to make it easy for those new to embedded systems to be able to use hardware in-system debuggers, saving them from the need to purchase something that likely would have cost them as much as the board.
[18:55:12] <A2Sheds> http://imagebin.org/185636 the encoder that died

[23:09:44] <skunkKandT> spindle encoder swapped... (small redesign)

[23:13:20] <danimal_laptop> :)
[23:13:23] <skunkKandT> Jymmm: mechanical failure... Not related to wiring...
[23:13:41] <Jymmm> skunkKandT: well that sucks
[23:13:52] <Jymmm> skunkKandT: More duct tape? Devcon?
[23:14:14] * Jymmm slapus danimal_laptopus
[23:14:16] <danimal_laptop> i got my mobo and goodies for the new mill. i ended up with a d525mw mobo
[23:15:45] <skunkKandT> the encoder didn't seem to like side torque.. but it said it should handle 80lbs
[23:16:01] <skunkKandT> we added a bearing to the nose... so time will tell
[23:16:04] <Jymmm> skunkKandT: Yeah for crappy specs! NOT!
[23:16:13] <Jymmm> s/yeah/yay/
[23:18:39] <mrsun> hmm, is there a name of the bearings used in the BK blocks for ballscrews? :)
[23:21:36] <danimal_laptop> i would assume you'd use some sort of angular contact bearings or radial ball and thrust bearings
[23:22:48] <mrsun> is there one or two bearings in there? :)
[23:23:31] <danimal_laptop> i dunno, i'd assume there's a radial bearing and a thrust bearing on each end
[23:23:38] <danimal_laptop> but i dunno

[23:28:14] <DrNoboto> hey. i'm having trouble installing emc on ubuntu 10.04 using the provided script
[23:28:39] <DrNoboto> basically the package isn't found
[23:29:12] <DrNoboto> the linuxcnc repo seems to be added, but the only packages apt finds are the hostmot firmwares
[23:29:38] <DrNoboto> which means i get the "package emc2 is not available, but is referred to by another package" error...
[23:30:07] <DrNoboto> might be more of any apt problem, but i thought i'd try here first, since it could also be a script or repo problem i guess...

[23:38:52] <skunkKandT> 2 race bearing
[23:38:59] <DrNoboto> or perhaps the unilateral phase detractor isn't direcly in line with the panametric fam
[23:39:07] <skunkKandT> we just added a third
[23:40:10] -!- servos4ever has quit [Quit: ChatZilla 0.9.85 [SeaMonkey 2.0.11/20101206162726]]
[23:40:20] <skunkKandT> we think that the shaft through the bearing in the encoder was glued in.
[23:41:06] <skunkKandT> because now it is really really loose :0 and we have a few hundred hours run time on it (only)
[23:42:41] <danimal_laptop> i still dont have spindle encoders on my mill
[23:42:48] <danimal_laptop> mills
[23:42:58] <danimal_laptop> i do have one on the lathe though
[23:43:49] <danimal_laptop> skunkKandT: do you have a cnc lathe, beisdes that huge one with the analog control or whatever it is?
[23:45:05] <skunkKandT> not yet
[23:45:26] <skunkKandT> we have a nice monarch manual and an old old larger lathe
[23:46:02] <skunkKandT> Can't wait to get the Cincinnati going though
[23:46:03] <danimal_laptop> cool
[23:46:37] <danimal_laptop> i ran a small monarch for a while
[23:46:53] <skunkKandT> it is one heck of a machine.. smooooot
[23:46:59] <skunkKandT> *smoooth
[23:47:04] <danimal_laptop> yea
[23:50:27] <danimal_laptop> i need a new manual lathe
[23:50:42] <DrNoboto> i need a lathe
[23:50:47] * DrNoboto lives in an apartment :(
[23:50:54] <danimal_laptop> mine works ok but it's overhead belt driven
[23:51:02] <danimal_laptop> yea that makes it hard
[23:52:21] <danimal_laptop> i'd like something without babbit bearings
