[00:02:29] <furrywolf> it's not holding torque you're thinking of, but yes, steppers lose a lot of torque at higher speeds.
[00:03:10] <furrywolf> you can try adding springs or counterbalances to your axis, use a fancier stepper motor, use a higher drive voltage, or run slower.
[00:03:54] <furrywolf> doubling the drive voltage will roughly double the torque at a given speed
[00:04:31] <furrywolf> doubling the money spent on the stepper motor will also roughly double the torque at a given speed and drive voltage. :)
[00:05:21] <furrywolf> if you look about 2/3rds of the way down on the page you pasted, they give a torque vs speed graph
[00:05:38] <furrywolf> you can also sometimes get more top speed by decreasing the maximum acceleration
[00:13:37] <furrywolf> bbl, wolfy bedtime.
[00:13:58] <trentster> furrywolf: thanks
[00:14:21] <furrywolf> glad to help. :)
[00:14:53] <trentster> I forgot to mention I am running all steppers in "parallel"
[00:15:00] <trentster> not sure if thats optimal or not
[00:15:16] <furrywolf> yes
[00:15:27] <furrywolf> series is much worse for high-speed torque
[00:15:40] <trentster> Now I understand why a lot of people always spec a much larger stepper for the Z axis, makes sense now
[00:16:37] <just_pink_> hi
[00:16:49] <just_pink_> someone here at this time?
[00:17:23] <trentster> just_pink: its pretty quite at this time, most of the US folk are in the land of Dreams
[00:17:23] <furrywolf> torque at high speeds is limited by inductance. if your steps are short, there's not enough time for the current in the windings to rise much, due to the motor's inductance. wiring in parallel gives a lower inductance than wiring in series, so it works better. increasing the drive voltage forces current to flow quicker. spending money on a lower-inductance stepper also causes the current to rise quicker.
[00:17:43] <furrywolf> one trick I've seen people do is putting air shocks on their Z axis to support the weight.
[00:17:46] <just_pink_> http://www.ebay.com/itm/NEW-15-Inch-4Wire-Resistive-Touch-Screen-Panel-Kit-USB-Controller-H1222-YD-/181789085865?pt=LH_DefaultDomain_0&hash=item2a537950a9
[00:18:00] <just_pink_> how this kit work??
[00:19:00] <trentster> furrywolf: thanks - you sure know your stuff. I wanted to ask you, for a DIY router using ballscrews on all axises, should I drop my microstepping to "8" or "4" instead of the current 16 I am using?
[00:19:39] <trentster> I recall reading somewhere this will improve torque as well at the expense of possible noise, precision, and resonance?
[00:19:56] <furrywolf> only if your top speed is limited by how fast you can generate pulses. if you're using a parallel port breakout board, this might be the case. if you're using good hardware, it won't be.
[00:20:14] <trentster> I am using leadshine digital drivers, not sure if this counters noise at smaller stepping
[00:20:22] <furrywolf> most non-chinese drivers will generate a good waveform no matter what the microstepping is
[00:20:40] <furrywolf> most chinese drivers will suck no matter what it is. :)
[00:20:49] <trentster> furrywolf: leadshines are chinese, but pretty good imho
[00:20:59] <trentster> I have seen some folks prefer them to geckos
[00:21:28] <furrywolf> geckos detect high step rates and transition to an optimized-for-torque waveform...

[00:21:57] <just_pink_> it's look soo cool
[00:22:42] <furrywolf> now, bbl. bedtime!
[00:22:46] <trentster> just_pink: yeah it is cool
[00:22:55] <trentster> furrywolf: sleep well mate - and thanks for the info
[00:23:07] <just_pink_> but what driver it's use?
[00:23:55] <trentster> I think it just interprets finger tuck as mouse pointer location
[00:24:53] <just_pink_> but you need to calibrate it..
[00:26:12] <trentster> not sure, I have never used one
[00:27:23] <just_pink_> i want to connect the screen with nice arm.
[00:30:28] <just_pink_> I have 2 A4 pages full of s
[00:30:44] <just_pink_> I have 2 A4 pages full of stuff that i want to add to the machine.
[00:32:04] <just_pink_> trentster: do you know where i can find nice and reliable voltmeter?
[00:34:47] <trentster> just_pink: I use a Fluke
[00:34:58] <trentster> its nice and reliable - but not exactly cheap.
[00:35:43] <trentster> try and get something that is true rms - especially if you working with electronics
[00:36:00] <Crom> I want a fluke. But limp along with harbor freight multimeters
[00:36:03] <just_pink_> there it Fluke for panel??
[00:36:37] <trentster> http://en-us.fluke.com/products/digital-multimeters/fluke-177-digital-multimeter.html
[00:36:45] <just_pink_> I have few from HF
[00:36:46] <just_pink_> thay nice but I want something good for the panel..
[00:36:50] <trentster> oh you mean for panel of enclosure?
[00:37:13] <trentster> you can just use an ebay cheapie, should be fine, its what I use
[00:38:15] <just_pink_> thay junk..
[00:38:15] <just_pink_> I want some brand name.
[00:40:19] <trentster> not sure
[00:41:59] <just_pink_> what is better digital or analog?
[00:43:40] <just_pink_> phantoxeD: hi
[00:46:45] <just_pink_> someone know about good vold meter for panel?
[00:46:48] <just_pink_> volt*
[00:47:22] <just_pink_> ?
[00:50:53] <just_pink_> what is better digital or analog?
[00:50:54] <just_pink_> what is better digital or analog?
[00:54:27] <just_pink_> I think I wil go with analog
[00:59:22] <just_pink_> http://www.abb.com/productdetails/ABB2CSG113230R4001
[00:59:26] <just_pink_> soooo cute
[01:02:24] <just_pink_> hi nofxx
[01:02:31] <archivist> rare to fit voltmeters on cnc panels
[01:03:39] <just_pink_> 72V 20A DC
[01:06:02] <just_pink_> but i want to know that the power supply is working good
[01:11:17] <just_pink_> http://www.ebay.com/itm/MK-Electronics-701-13-Analog-Panel-Mount-DC-Volt-Ohms-Meter-300-Volt-Gauge-/161526410667?hash=item259bb96dab&vxp=mtr
[01:11:23] <just_pink_> look soo cute
[01:13:17] <just_pink_> Fluke
[01:13:18] <just_pink_> http://www.ebay.com/itm/Fluke-0-500-Volts-Large-Square-Analog-Panel-Meter-FREE-Shipping-in-USA-/391056245649?pt=LH_DefaultDomain_0&hash=item5b0cc4c391
[01:13:23] <just_pink_> for panel!!
[01:18:25] <just_pink_> http://www.ebay.com/itm/BAM-48-100VD-Analog-Panel-Meter-0-100-DC-Voltmeter-48x48mm-/201074916252?pt=LH_DefaultDomain_0&hash=item2ed0ffbb9c
[01:18:36] <just_pink_> what is BAM?
[01:18:49] <just_pink_> this is good band name?
[01:18:59] <just_pink_> or junk?
[01:21:59] <archivist> never heard of BAM, looks american
[01:22:49] <archivist> as long as the LEDs are on on the stepper/servo drivers you know the powere is on
[01:23:09] <just_pink_> and i need re make the plate inside
[01:23:36] <just_pink_> the drivers inside the panel..
[01:24:14] <archivist> open the panel only if there is a problem :)
[01:24:32] <just_pink_> i can't see them from outside
[01:25:15] <archivist> what I am trying to say, is this a real need, or a luxury
[01:25:35] <just_pink_> real need
[01:25:45] <just_pink_> I want to be able to monitor it.
[01:29:00] <trentster> archivist: howdy remember the other day we were discussing my gantry stiffness etc. Not related to the gantry I wanted to get your opinion on what microstepping you recommend for my setup with all axis being driven by ballscrew?
[01:29:37] <trentster> I read somewhere that 16 microsteps loses a lot of torque for cnc routers driven by ballscrew, do you think I should reduce to 8 or 4 microsteps?
[01:30:31] <just_pink_> trentster: you know that now servo and stepper cost the same?
[01:30:50] <trentster> just_pink: nope - not in my world they dont
[01:30:58] <archivist> microsteps mainly give you a smoother system with less resonance
[01:31:58] <just_pink_> trentster: G320x cost about 115$ stepper driver cost about 100
[01:32:27] <just_pink_> for 15$ you will get much much better system.
[01:32:35] <archivist> I tend to half step for the power/torque
[01:33:45] <archivist> but if going slowly through resonance I use 8
[01:33:50] <trentster> just_pink: thats the driver, but it still needs a servo motor right?
[01:33:53] <just_pink_> half is the strongest way,
[01:34:14] <just_pink_> yes.. almost the same also..
[01:34:37] <just_pink_> sometime servo even cost less..
[01:34:49] <just_pink_> it's just DC motor..
[01:34:57] <trentster> archivist: yeah thats what I thought, I am using 16 at the moment and my machine is probably no way near that accurate anyway, I should probably drop to 4 or 8
[01:35:45] <trentster> just_pink: where is the url for servo motor at the same cost - this should be interesting
[01:36:33] <just_pink_> what is the size that you nnned?
[01:36:36] <just_pink_> need*
[01:36:58] <trentster> nema 23
[01:37:02] <just_pink_> half is te strongest way with steppet..
[01:37:20] <just_pink_> and torqe?
[01:37:35] <trentster> 470Oz should be fine
[01:37:48] <just_pink_> the 16, 8, 4 it's just to get it more acurate.
[01:38:09] <just_pink_> 470Oz cm? in? meter?
[01:40:00] <trentster> just_pink: something equivalent to this https://oceancontrols.com.au/MOT-128.html
[01:42:51] <archivist> just_pink, more microsteps is not always more accurate
[01:43:34] <just_pink_> you hope it will..
[01:43:51] <just_pink_> this is why it exsist
[01:44:05] <archivist> http://www.micromo.com/microstepping-myths-and-realities
[01:44:16] <archivist> read that :)
[01:44:17] <just_pink_> trentster: http://www.automationtechnologiesinc.com/products-page/nema23-m-dc-servo-motor/3-axis-nema23-350ozin-60v20a-psu-g230x-gecko-driver
[01:45:01] <just_pink_> just the motor http://www.automationtechnologiesinc.com/products-page/nema23-m-dc-servo-motor/skewed-rotor-design-nema23-dual-shaft
[01:45:29] <trentster> archivist: thanks I actually read that page yesterday ;-)
[01:46:04] <trentster> The only thing I was worried about was resonanace and stepper noise but I dont think the stepper noise will be an issue with digital drivers I am using
[01:46:05] <archivist> helps to know the myths too
[01:46:27] <trentster> yeah - thats a great page
[01:46:53] <archivist> I use a chinese driver leadshine or look alike
[01:47:19] <trentster> just_pink: thanks for the link - I had no idea servos had become so cost effective.
[01:47:36] <just_pink_> you see.
[01:47:41] <trentster> archivist: I use leadshine AM882 with stall detection - so far no complaints
[01:47:51] <archivist> but that driver makes you use stepdir which is sill a pain
[01:48:50] <just_pink_> trentster: why do you work with micro steps?
[01:49:03] <just_pink_> it's too fast?
[01:49:05] <trentster> but the driver knows where the servo is at all times right, its still closed loop?
[01:49:41] <trentster> just_pink: I use microsteps for smoothness and resolution I guess
[01:49:46] <just_pink_> trentster: what is the ball screw pitch?
[01:50:45] <just_pink_> to get smoothness you need to set the acceleration right
[01:50:50] <trentster> just_pink: 5
[01:50:58] <just_pink_> 5 mm?
[01:51:02] <trentster> yup
[01:51:43] <just_pink_> without any micro stepping you will get 0.025 mm resulotion.
[01:52:06] <archivist> and this is what you get half step http://www.archivist.info/cnc/screw_error/
[01:53:17] <trentster> wow! so why on earth would anyone actually need like 16 microsteps then?
[01:53:22] <just_pink_> trentster: with half step it will drop to 0.01 and then probably the backlash and temperature change will make much more difference
[01:54:02] <trentster> just noise and longevity of mechanical components?
[01:54:21] <archivist> never dream about the errors, measure the errors
[01:54:50] <just_pink_> trentster: stay wirth full step, if your machin is router based you are not going to see any difference.
[01:55:27] <archivist> depends on quality not form
[01:55:56] <trentster> just_pink: thanks - that makes sense, will test it now - and if stepper noise does not bug me, I will use it
[01:56:36] <just_pink_> after the change in the Drivers from 1/16 to 1
[01:57:00] <just_pink_> you wil have to set the acceleration again in linux cnc.
[01:57:03] <trentster> I also need to take machine apart at some point and put it back together using locktite, I notice screws are coming loose because of vibration -(sigh) the joys!
[01:57:41] <just_pink_> trentster: what kind a machine is that??
[01:57:56] <just_pink_> dremel based?
[01:58:01] <archivist> shakeproof washers or lock nuts
[01:58:31] <trentster> just_pink: nah using a spindle
[01:58:48] <just_pink_> but what machine is that?
[01:59:20] <trentster> just_pink: its a DIY build let me grab a pic for ya
[01:59:56] <just_pink_> fine.
[02:00:01] <trentster> http://monosnap.com/image/qPcJ1Dc51TkTfoBlOBS2ul3x50rt3N
[02:00:13] <trentster> thats while I was building it looks a bit different now
[02:00:23] <trentster> strengthened wider gantry etc.
[02:00:36] <trentster> * I must take an updated pic
[02:00:56] <just_pink_> hoo now I remember - you had the issue with the flaxebility..
[02:01:22] <archivist> everybody has machine flex
[02:01:31] <archivist> the amount varies
[02:02:10] <just_pink_> yeh..
[02:02:51] <just_pink_> I want some day to make an epoxy granit to the back of the machine
[02:03:00] <archivist> narrow columns on mills a common cause
[02:03:43] <Deejay> moin
[02:03:49] <just_pink_> moin?
[02:03:56] <just_pink_> morning?
[02:03:58] <Deejay> yep
[02:04:03] <just_pink_> hehe
[02:04:07] <Deejay> hi :)
[02:04:18] <just_pink_> hi.
[02:04:35] <just_pink_> I'm still working on papers..
[02:05:09] <just_pink_> and to the boring stuff of calculated and shape the panel.
[02:05:27] <just_pink_> I need to out sorce it..
[02:05:37] <just_pink_> I'm hate to do it.
[02:06:08] <just_pink_> soooo freakin boooring
[02:07:34] <just_pink_> someone want to do it for me?
[02:07:40] <just_pink_> I will pay you.
[02:08:56] <trentster> so the machine looks like this now: just took some new pics, still a mess tho :P
[02:08:58] <trentster> http://monosnap.com/image/YWAe7Fh9XOwitXkZniDJA0CnXOHg4u
[02:09:50] <trentster> http://monosnap.com/image/1qWHMHfoAxDF9Zmez9hZSxdtyE0Hw7
[02:10:18] <just_pink_> the spindle sooo small wow.
[02:10:22] <just_pink_> tiny.
[02:10:29] <trentster> http://monosnap.com/image/pYJr5AJCfkYlUoJArGZzHKQQ03HPdx
[02:10:55] <trentster> heh yeah its a 400W spindle - will upgrade when budget/pocket says go ahead :-)
[02:11:11] <just_pink_> you need to rotate the drivers 90 deg.
[02:11:36] <just_pink_> 400W is't ok..
[02:12:27] <archivist> trentster, when the machine is stopped, place a dti on the bed, with the plunger on the gantry side, push back and forward, how much does it move
[02:13:13] <trentster> just_pink: if you want to send me a 2.2KW water cooled spindle + VFD, I would not be to proud to say yes ;-)
[02:13:18] <archivist> this will rotate around the ballscrew nut rotating the gantry twisting the two sides
[02:13:41] <just_pink_> trentster: but you make me the electrical panel.
[02:13:45] <archivist> may not be here for answer waiting to be picked up
[02:14:50] <trentster> archivist: will take me awhile to retest - but from what I recall it was about .25 of a mm
[02:15:48] <just_pink_> trentster: http://www.ebay.com/itm/2-2KW-WATER-COOLED-SPINDLE-MOTOR-2-2KW-VFD-INVERTER-MILLING-GRILLING-GRIND-/171047740473?pt=LH_DefaultDomain_0&hash=item27d33d6439
[02:16:09] <archivist> something like I expected, as that force comes from your cutting forces adding to inaccuracy
[02:16:11] <just_pink_> for this price i will send you 2
[02:16:20] <just_pink_> but you make the panel..
[02:16:45] <archivist> just_pink, you need the experience :)
[02:16:57] <trentster> just_pink: you also have to factor in spindle mount, and water pump
[02:17:44] <just_pink_> water pupm 50$..
[02:17:55] <archivist> having a spindle too powerful for the frame does not make sense
[02:18:03] <just_pink_> I will make you Stainless mount,
[02:18:36] <trentster> just_pink: you are a very generous dude!
[02:19:05] <just_pink_> but you are going to deal with 400-500 terminal blocks..
[02:19:20] <just_pink_> and do it by the book of the OCD.
[02:20:03] <trentster> archivist: yeah, there is definately some unwanted flex there for sure. If I had to make it again I would probably lose the supported rail as well and use NSk linear used kit for all axis. They seem to be available pretty cheap used for South Korea
[02:21:05] <archivist> use two ball screws either side to remove that twist
[02:21:10] <just_pink_> trentster: and please rotate the drivers 90 deg, this wat the heat build up in the heatsink without any way to go up, so it's almost useless.
[02:21:33] <just_pink_> two ball screws = 2 motors
[02:21:52] <archivist> or a belt between the two
[02:22:44] <trentster> just_pink: yeah I will move them, this is just a temporary setup on a piece of mdf, what I still need to do is put in another shelf for the computer, cut the front panel from acrylic and then cut holes in the back for fans etc.
[02:23:04] <trentster> Hopefully my cnc will handle cutting through that steel of the enclosure at very slow feed rates
[02:23:41] <just_pink_> you sont have to cut the steel with the cnc.
[02:24:17] <just_pink_> just make large hole and make brash aluminom plate
[02:24:21] <just_pink_> don't*
[02:25:15] <trentster> archivist: yeah was thinking of adding an additional ballscrew for y axis, but the place I got the current one from does not seem to carry it anymore. I do have a spare stepper but the costs add up will mean additional gantry mount and BK blocks
[02:26:16] <trentster> just_pink: yeah that would be my second option, cut a hole with a dremel and use aluminium, but first option is to cut directly, neater and nicer that way.
[02:27:21] <just_pink_> the plate it better,
[02:27:27] <trentster> I need to go to CNC boot camp and get some engineering help with this :P either that or join a maker community space somewhere to get access to big machinery
[02:28:58] <just_pink_> the plate give you the ability to make changes
[02:29:19] <trentster> just_pink: yeah - you are right now that I think about it, plate makes more sense
[02:29:20] <just_pink_> where are you from?
[02:29:41] <trentster> Australia, Melbourne - you?
[02:29:47] <just_pink_> NY
[02:29:59] <trentster> nice
[02:30:16] <just_pink_> I think I'm te only one here from NY
[02:31:11] <trentster> except for the NYC CNC guy :-)
[02:31:31] <trentster> but he is not a linuxcnc user it seems
[02:31:38] <just_pink_> cold as hell all the times but 3 mount hot as hell
[02:31:59] <just_pink_> nyc cnc is here??
[02:32:17] <trentster> nah - I am just kidding
[02:32:40] <just_pink_> he is so handsome
[02:33:04] <just_pink_> I like him and his videos.
[02:33:15] <trentster> I am more attracted to his Tormachs
[02:33:56] <just_pink_> at the begining I want to buy a tormach or used cnc machine.
[02:34:39] <just_pink_> but I'm living in second floor
[02:35:01] <trentster> your neighbours must love you!
[02:35:19] <just_pink_> so.. I had to go with something that I can move with muscle force.
[02:35:24] <just_pink_> why?
[02:35:28] <trentster> noise
[02:35:40] <just_pink_> no noise
[02:35:48] <just_pink_> super quite
[02:35:54] <archivist> not making much then :)
[02:36:13] <trentster> your machine in a sound proof enclosure?
[02:36:29] <just_pink_> I make the stack lighet becase all the time I'm forgat it working.
[02:36:33] <just_pink_> no
[02:37:17] <just_pink_> and it use very big servos. (1125 Oz/in)
[02:37:49] <archivist> it is the cutting that is noisy not the motors
[02:38:05] <trentster> archivist: he I was just about to say that
[02:38:28] <just_pink_> less then 50 DB
[02:38:35] <just_pink_> spindle workin.
[02:38:37] <trentster> the motors can be 100% silent the bit cutting material will make mega noise
[02:38:41] <archivist> although my steppers vibrate the floors a bit
[02:39:02] <just_pink_> I want to make servo spindle conversion Direct drive.
[02:39:26] <trentster> just_pink: you got a photo of your machine?
[02:39:30] <just_pink_> and then I will be total heaven
[02:39:36] <just_pink_> G0704
[02:40:03] <just_pink_> very common machine..
[02:40:42] <just_pink_> green :(
[02:41:21] <just_pink_> http://www.sogi-tools.com/product_info.php?cPath=92&products_id=499
[02:41:39] <just_pink_> OMG!!! it is soooo cuuuuteeeeee machhheeein!!! soo cute!!
[02:41:43] <just_pink_> I want it!!
[02:41:53] <just_pink_> TOTAL PINK CNC!
[02:42:23] <trentster> just_pink: out of curiosity, are you male or female?
[02:42:24] <archivist> get a tub of paint!
[02:43:47] <just_pink_> trentster: it's not clear?
[02:44:06] <trentster> just_pink: tough? question?
[02:44:21] <trentster> lol - well there are various possible answers
[02:44:31] <archivist> I know the difference when I see dainty little hands :)
[02:44:45] <just_pink_> I'm female.
[02:46:17] <trentster> just_pink: :-) no offence intended, its just that I don't know many woman who are into CNC milling etc. Its a pleasant suprise
[02:46:31] <just_pink> http://i.imgur.com/xf8Qnq8.png
[02:46:51] <just_pink> trentster: ^
[02:47:08] <just_pink> http://i.imgur.com/1TqJubR.png
[02:47:37] <just_pink> http://i.imgur.com/jCbcQBx.png
[02:47:55] <just_pink> trentster: ?
[02:48:29] <trentster> just_pink: yup?
[02:48:41] <just_pink> you see the pics?
[02:49:08] <trentster> I did indeed - saw some hands with long nails and nail polish ;-)
[02:49:10] <archivist> someone was supposed to pick me up an hour ago...
[02:49:41] <trentster> archivist: hope you not waiting out on the street
[02:50:25] <just_pink> trentster: I'm in to CNC becuse I like to make stuff but dont like to work hard..
[02:50:34] <archivist> nope sitting at home
[02:50:37] <trentster> just_pink: me too
[02:50:59] <trentster> just_pink: what kind of stuff do you make?
[02:51:07] <just_pink> I'm thinking about make a 3d printer options..
[02:51:16] <just_pink> part for the machine.. :)
[02:51:22] <just_pink> not much..
[02:52:19] <just_pink> http://www.ebay.com/itm/All-Metal-J-head-Hotend-for-1-75mm-Filament-Bowden-Extruder-Reprap-3D-Printer-/381131169456?pt=LH_DefaultDomain_0&var=&hash=item58bd301eb0
[02:52:26] <just_pink> 11$
[02:52:50] <trentster> yeah I have a ton of spare 80/20 extrusion here, I was thinking of making a laser cutter or 3d printer with it
[02:53:37] <just_pink> laser i don't like. leave it to the pro..
[02:53:43] <trentster> You seen this? http://www.ted.com/talks/joe_desimone_what_if_3d_printing_was_25x_faster
[02:53:46] <trentster> amazing
[02:54:39] <just_pink> my machine can go up to 10M /M
[02:54:50] <just_pink> wayyy to fast
[03:00:57] <just_pink> I have Nema 23 stepper motor..
[03:01:16] <just_pink> maybe I can use it for the extruder.
[03:02:33] <trentster> just_pink: your enclosure pic you sent there, is that the cabinet you want to build?
[03:02:56] <trentster> its an odd shape for a enclosure - I assume its a cabinet?
[03:03:03] <just_pink> yes..
[03:03:18] <trentster> why 36 holes?
[03:03:34] <just_pink> I think I need more..
[03:05:20] <just_pink> 7 temp sensor, 5 motors 5 encoders, 1 main line, 1 main spindle, 1 stack light, 1 spindle light, any more...
[03:05:49] <just_pink> and many more*
[03:06:06] <just_pink> 5 limits
[03:06:13] <just_pink> probe
[03:06:27] <archivist> multiway connectors
[03:06:32] <just_pink> no!
[03:07:02] <just_pink> terminal blocks.
[03:09:00] <just_pink> archivist: there is no flexability in connectors..
[03:09:29] <archivist> sure there is, for instance I can swap axis motors over
[03:10:06] <just_pink> whay do i need to do it??
[03:10:53] <archivist> diagnosis when an axis fails
[03:11:26] <just_pink> I will take 4 wire out..
[03:11:39] <archivist> off to work...
[03:59:18] <just_pink> those are the leftovers http://i.imgur.com/HLnypDh.jpg
[03:59:19] <just_pink> any idea?
[04:44:29] <just_pink> micro
[04:53:03] <XXCoder> lasers all way down
[04:54:21] <XXCoder> just_pink: leftovers after using stuff to build your machine?
[04:55:44] <just_pink> no..
[04:55:56] <just_pink> just junk that i've collect ovet the years..
[04:56:07] <XXCoder> oh
[04:56:08] <XXCoder> well
[04:56:16] <XXCoder> I see enough to make a basic cnc machine
[04:56:23] <XXCoder> maybe not enoygh controllers
[04:56:54] <just_pink> 3 steppers
[04:57:03] <just_pink> Nema 23
[04:57:18] <XXCoder> and what appears to be tiny and big spindle
[04:57:19] <just_pink> 1 big servo 1125 oz /in
[04:57:56] <just_pink> 1 sloooow dc motor 1:300 gear (the one that i'm holdeing)
[04:58:03] <just_pink> 1:3000*
[04:58:10] <XXCoder> dang
[04:58:10] <just_pink> and 1 G320x
[04:58:29] <XXCoder> yeah besides that very solow one, you can maqke basic cnc router
[04:58:32] <XXCoder> mill maybe
[04:58:48] <XXCoder> if you already has nice mill cnc you can even just make parts for it lol
[04:58:55] <just_pink> but i have nice milling machine..
[04:59:08] <XXCoder> router is good for 2d stuff
[04:59:13] <XXCoder> larger area
[04:59:39] <XXCoder> dont think it can pull off full 4'x8' work space one though lol
[04:59:39] <just_pink> I want to make 3d extruder for R8 tool holder.
[05:00:03] <XXCoder> cool. dont know much about printer :)
[05:00:10] <just_pink> me also..
[05:00:12] <just_pink> but!
[05:00:21] <just_pink> you just need few stuff
[05:00:33] <XXCoder> you has HUGE advange
[05:00:39] <XXCoder> you got mill to make stuff
[05:01:20] <XXCoder> if you got lathe thats added help, to make supported rods
[05:01:20] <just_pink> PID controller, extruder and heated bad
[05:01:26] <XXCoder> maybe not supporred
[05:02:20] <just_pink> so.. abour 100$ you can convert your cnc to 3d printer also..
[05:02:32] <XXCoder> dont think 3dprinter needs hefy supported rods lol
[05:02:48] <XXCoder> I got sbr20, 16, 12 kit I can evenually make into 3d printer
[05:02:57] <XXCoder> I rather have lasers but I dont wanna risk eyesight
[05:03:42] <just_pink> don't mess with lasers
[05:04:06] <just_pink> class D lasers can blind you also from reflections.
[05:04:29] <just_pink> small end mill.. and you rock
[05:04:33] <XXCoder> If I ever get laser it'll be small machine with proper covers
[05:04:57] <just_pink> I work with laser cutter
[05:05:08] <just_pink> dont like it at all
[05:05:26] <XXCoder> yeah?
[05:05:39] <just_pink> the burns edges and the smoke..
[05:06:10] <just_pink> and you have to supply compressed air
[05:06:28] <XXCoder> fun
[05:06:35] <just_pink> sometimes Argon or CO2
[05:06:40] <just_pink> not much..
[05:06:47] <XXCoder> I wonder if theres way to "live supply" pressured air
[05:06:54] <XXCoder> for work part blowing for example
[05:07:00] <XXCoder> so I dont need compressor tank
[05:08:24] <just_pink> screw or eccentric compressor or turbine
[05:08:39] <just_pink> the screw based is soo quite.
[05:08:55] <just_pink> the othes noisy
[05:09:00] <XXCoder> not bad, while I cant hear anything, neighbors can lol
[05:09:57] <just_pink> go with fridge compresorr that will work all the time with heat controller and pressure switch
[05:10:15] <just_pink> and very larg tank..
[05:10:47] <XXCoder> ok
[05:10:55] <just_pink> this way it will work ait will work nise for short times..
[05:11:02] <XXCoder> I will work with mainly wood
[05:11:09] <XXCoder> so most times it wont be needed
[05:11:20] <just_pink> hate it..
[05:11:23] <XXCoder> I do plan to build vacuum attachment though to clean it
[05:11:41] <just_pink> water jet much more nice.
[05:12:13] <XXCoder> yea heard many good stuff with it, and I was running big cnc router near one
[05:12:20] <XXCoder> so I checked it sometimes. nice.
[05:12:24] <XXCoder> so dirty though.
[05:12:44] <just_pink> or EDM
[05:12:59] <XXCoder> it was so dirty I almost can belive that if you pull it to parts, sandblasted, repainted it, and all is nice and shiny
[05:13:10] <just_pink> EDM is freaking awesome stuff
[05:13:15] <XXCoder> once last part is bolted on (but not water refilled) its dirty already lol
[05:13:35] <XXCoder> new one to me, edm
[05:14:04] <XXCoder> is it one that uses wire and electricity to cut?
[05:14:32] <just_pink> https://en.wikipedia.org/wiki/Electrical_discharge_machining
[05:14:34] <just_pink> yes
[05:14:37] <just_pink> soo nice
[05:14:43] <just_pink> so acurate
[05:14:48] <XXCoder> my friend used one at college
[05:14:54] <XXCoder> pretty impressive
[05:15:04] <just_pink> and you can cut any metal even super aloys
[05:15:53] <just_pink> but you need a cnc with high speed spindle to make the electrodes from graphite
[05:16:25] <just_pink> sink EDM it's basiclly 1 axis machine..
[05:16:34] <just_pink> work like punch
[05:16:51] <XXCoder> 2d only I think? with offsets its closer to 2.5d like mill and router
[05:16:56] <XXCoder> though in different way
[05:17:19] <just_pink> yeh.. you dont have to fo all the way..
[05:17:41] <just_pink> If you want to cut complex shape you need wire EDM..
[05:18:47] <XXCoder> fun
[05:19:08] <XXCoder> I'm still waiting for my spindle and power source for it :(
[05:19:16] <XXCoder> wish theres instant transportion lol
[05:20:11] <just_pink> I want to sleep
[05:20:22] <just_pink> soo borig to do the panel
[05:21:32] <just_pink> https://www.youtube.com/watch?v=fRPmSgfIJqY
[05:24:40] <just_pink> It is just a coil!!
[05:24:44] <just_pink> WhaT
[05:24:51] <just_pink> I want to make it.
[05:27:29] <XXCoder> looking
[05:28:00] <XXCoder> just_pink: dang
[05:28:15] <XXCoder> now thats dangerous lol wwrong touch and it grounds out
[05:28:31] <just_pink> it is sooo simple to make
[05:28:36] <just_pink> 12V 10A
[05:28:40] <just_pink> coil
[05:28:46] <just_pink> sring
[05:28:51] <XXCoder> kinda reminds me of discovery of how to make cheap aluminium
[05:29:01] <just_pink> how??
[05:29:07] <XXCoder> white powder + LOTS electricity = alum
[05:29:12] <just_pink> https://www.youtube.com/watch?v=Hxtg2nAIYw4
[05:29:26] <just_pink> white powder??????
[05:29:28] <XXCoder> did you know usa spire is capped with aluminium? it was valuable then
[05:29:39] <XXCoder> alum oxide oxide :) AlO2
[05:29:59] <just_pink> and what do you get it?
[05:30:37] <XXCoder> http://www.rocksandminerals.com/aluminum/process.htm
[05:31:22] <just_pink> the edm that thay show work with magnetic based, like the magnetic base dial indicator
[05:31:30] <XXCoder> 100,000A to 150000A
[05:31:33] <XXCoder> insane.
[05:31:45] <just_pink> yeh..
[05:32:04] <XXCoder> still cheaper than just trying to mine alum. most was in useless not metallic form
[05:32:28] <just_pink> but edm drill press can make fine hex hole and alot of nice stuff
[05:33:00] <just_pink> XXCoder: I have 4X3 foot plat 1/8" 2024-t3
[05:33:05] <just_pink> do you want some?
[05:33:25] <XXCoder> nah, thanks thoughg
[05:35:02] <XXCoder> wow
[05:35:20] <XXCoder> if interrupted for 4 hours, it solidifies and need expensive repairs
[05:35:39] <XXCoder> I bet you they got in least 2 backup systems
[06:35:45] <just_pink> http://www.aliexpress.com/item/New-R8-arbor-NBH2084-Boring-head-system-with-8pcs-20mm-indexable-holder-CNC-Milling-tool/32331705416.html
[06:36:45] <just_pink> someone know where i can get the arbor that show at the third pic?
[06:36:48] <just_pink> XXCoder: ?
[06:36:57] <XXCoder> looking
[06:37:12] <XXCoder> it displays model number
[06:37:18] <XXCoder> maybe a way to find it
[06:38:23] <just_pink> http://g01.a.alicdn.com/kf/HTB1U_uWIXXXXXbkXpXXq6xXFXXXA/New-R8-arbor-NBH2084-Boring-head-system-with-8pcs-20mm-indexable-holder-CNC-Milling-tool.jpg
[06:38:40] <just_pink> this ^
[06:39:29] <XXCoder> R8 NB2084
[06:39:54] <XXCoder> hmmnot good result
[06:40:18] <just_pink> yeh :(
[06:40:36] <XXCoder> maybe http://www.cart100.com/category/50021234/Boring_tool/?&p=23
[06:41:17] <XXCoder> that things dang expensive
[06:41:22] <just_pink> It's give me a-lot of stuff
[06:41:37] <just_pink> it suld be about 20-30$
[06:45:33] <just_pink> http://www.aliexpress.com/item/R8-boring-shank-for-F1-12-F1-18-F1-25-boring-head-Thread-of-draw-bar/32230054223.html
[06:45:37] <just_pink> 13$!
[06:45:52] <XXCoder> way to go on discovery
[06:46:09] <just_pink> 24.54 + shipping :(
[06:48:11] <XXCoder> cheaper than $500 shipped
[06:48:30] <just_pink> but I dont know hat it the thread on he G0704
[06:49:57] <XXCoder> dunno too
[06:53:43] <just_pink> Drawbar Thread Size 7/16-20
[06:55:48] <herron_> often it is a case of making up extra drawbars for different threads
[06:59:54] <just_pink> http://www.shars.com/r8-shank-1-1-2-18-threads-for-boring-head
[07:01:06] <just_pink> this is perfect but if it was with slightly larger faces it will best to mount stuff
[07:13:47] <XXCoder> night :) hopefully my stuff arrives tomorrow but not likely :P
[07:16:47] <just_pink> hope for you..

[07:26:33] <skunkworks> Good morning
[07:26:33] <greg___> wow, those prices are out of line
[07:27:32] <just_pink> good morning.
[07:28:00] <just_pink> someone is really smoke somthing in grizzly...
[07:29:22] <just_pink> http://www.grizzly.com/products/Mini-Mill-Retrofit-Kit-Pro-Series-Servo-for-G0704/T25440
[07:29:25] <just_pink> WOOOW
[07:29:35] <just_pink> $5,500.00
[07:29:44] <just_pink> and this is "SALE"
[07:29:51] <just_pink> WTF!
[07:30:32] <greg___> for people who want plug and play.
[07:30:48] <just_pink> you dont even get the ballscrew..
[07:30:52] <archivist_herron> play/pray
[07:31:10] <just_pink> so I can sell my machine for 20K easy..
[07:31:14] <greg___> sure plug and pray
[07:31:40] <just_pink> I will buy hass :)
[07:32:44] <greg___> I haven't looked at their site for years.
[07:32:47] <just_pink> look, 3 axis stepper motors+drivers and psu!
[07:32:48] <just_pink> http://www.grizzly.com/products/Benchtop-Retrofit-Kit-with-Stepper-Controls-and-Hardware/T24252
[07:32:51] <just_pink> 3K
[07:33:13] <just_pink> what is wrooong with them?
[07:33:40] <greg___> flashcut isn't cheap, I think
[07:34:12] <just_pink> but all the other stuff very cheap.. (like tools, end mill, etc..)
[07:34:44] <greg___> chinese probably
[07:34:55] <just_pink> but with the conversion it will cost more than the tormach
[07:35:21] <greg___> yeah, but if the iron is already in your shop, some will choose this route
[07:35:47] <greg___> kids are up, BBL
[07:36:31] <just_pink> OK
[07:57:15] <malcom2073> Heh, tabletop stuff is *expensive* because everyone has room for it
[08:00:18] <just_pink> I make my own conversion..
[08:00:27] <malcom2073> That's the way to do it, WAY cheaper
[08:00:47] <just_pink> and better...
[08:01:29] <just_pink> whan I plug the panel to the main line, I want an indicator
[08:01:37] <_methods> smoke?
[08:01:46] <_methods> usually a good indicator
[08:01:51] <malcom2073> heh
[08:02:02] <just_pink> panel indicator light..,,
[08:02:09] <_methods> oh that sounds safer
[08:02:12] <just_pink> but what it'smore correct?
[08:02:24] <just_pink> red or green?
[08:02:26] <_methods> which is more fun?
[08:02:54] <_methods> purple
[08:03:03] <just_pink> I think It should be red
[08:03:11] <_methods> blue
[08:03:30] <malcom2073> My lathe has an orange one for hot spindle control
[08:04:02] <just_pink> and after I'm thern on the main swich the red go off and green should be on.
[08:04:46] <_methods> http://www.business-standard.com/article/pti-stories/cannabis-may-help-treat-bone-fractures-study-115071700646_1.html
[08:04:49] <_methods> heheh
[08:04:56] <_methods> grandmas all over gonna be smokin weed now
[08:05:03] <just_pink> blue = mandatory
[08:05:09] <just_pink> red = stop
[08:05:24] <just_pink> green = good/work
[08:05:38] <_methods> magenta = lunch
[08:05:51] <just_pink> yellow/amber/orange = fail
[08:06:03] <malcom2073> What is a gap bed lathe for? Like, why would you remove the gap, just to get more throw for shallow pieces?
[08:06:12] <_methods> extra swing
[08:06:19] <_methods> yeah
[08:06:55] <malcom2073> My lathe I just picked up is a gap bed, just wondering
[08:07:09] <_methods> yeah it will buy you a few more inches usually
[08:07:12] <_methods> what'd you pick up?
[08:07:22] <_methods> now your dad can give me his 10ee
[08:07:23] <_methods> lol
[08:07:47] <malcom2073> He was actually going to replace his 10EE with this thing and sell the 10ee, but decided to sell it to me instead. Lemme find and upload pics, brb
[08:10:51] <archivist_herron> large faceplate in the gap too
[08:11:07] <_methods> that's what she said
[08:11:34] <archivist_herron> what the actress said to the bishop
[08:11:40] <_methods> heheh
[08:12:55] <malcom2073> heh
[08:13:22] <just_pink> I need a push button swich that not go deep
[08:13:36] <just_pink> http://www.ebay.com/itm/New-Safe-1pc-Red-Emergency-Stop-Switch-Flat-Momentar-Push-Button-22MM-1-NO-1NC-/171706194984?pt=LH_DefaultDomain_0&hash=item27fa7c9c28
[08:13:40] <malcom2073> _methods: http://mikesshop.net/lathe/grizzly/
[08:13:46] <malcom2073> it's a rebranded G9242
[08:13:56] <_methods> ahh
[08:14:07] <_methods> that won't replace a 10ee lol
[08:14:20] <malcom2073> It will easily replace the stuff my dad does on his 10ee haha
[08:15:00] <archivist_herron> poor engine crane
[08:15:13] <just_pink> someone know where to fine or what is the name of it?
[08:15:22] <malcom2073> That engine crane is fine, we're a couple pounds shy of capacity
[08:15:26] <malcom2073> :P
[08:15:44] <malcom2073> just_pink: You want a button that doesn't sink in like that? Or doesn't sink in as far
[08:15:45] <malcom2073> ?
[08:15:47] <_methods> oooh corn
[08:15:56] <just_pink> to button that not sink into a cylinder..
[08:16:43] <malcom2073> Lol yes, I live in a cornfield
[08:16:43] <archivist_herron> I see the web was inside one end but outside the screw the other
[08:16:51] <just_pink> malcom2073: It's can break the nails
[08:17:02] <_methods> taht southbend is in good shape
[08:17:13] <malcom2073> _methods: it's for sale!
[08:17:14] <_methods> i'm perv'n your other albums
[08:17:29] <malcom2073> Lol np
[08:17:29] <_methods> i already got that atlas
[08:17:31] <malcom2073> also look at /mill
[08:17:44] <_methods> yeah i've seen that
[08:17:49] <_methods> you got the kondia right?
[08:17:59] <malcom2073> just_pink: Yeah you can get that style button that doesn't sink in, trying to remember how to search for it haha
[08:18:01] <malcom2073> _methods: yeah
[08:18:39] <just_pink> mmm I'm try also..
[08:19:35] <malcom2073> I know I always see buttons at machine yard sales and the like, no clue what they're actually called haha
[08:19:57] * archivist_herron explores the southbend too
[08:20:41] <archivist_herron> I would keep it for the manual work
[08:20:53] <malcom2073> The g9242 is a manual lathe
[08:21:12] <malcom2073> And near new, I swear it's almost never been used. The southbend is well used heh
[08:22:00] <malcom2073> We were thinking of tearing out the leadscrew and putting in a ballscrew to cnc, but it's in such good condition, I'ma keep it manual and use it to learn machining, I'm fairly new
[08:22:29] <archivist_herron> my southebend is well worn too circa 1940s but can still do a reasonable job
[08:23:53] <just_pink> http://www.digikey.com/en/product-highlight/t/taiyo-yuden/lithium-ion-capacitors
[08:25:41] <just_pink> I've never know about that

[08:25:48] <just_pink> soo kool
[08:25:52] <just_pink> cool*
[08:26:03] <malcom2073> Haha fancy

[08:29:00] <malcom2073> There was a PC keyboard made out of those
[08:29:04] <malcom2073> it was like $1200
[08:31:19] <just_pink> ask for sample :)
[08:31:30] <malcom2073> heh
[08:33:21] <just_pink> malcom2073 form Reynholm Industries..
[09:41:43] <trentster> any fusion360 users here?
[09:46:31] <norias> yes
[09:50:31] <trentster> norias: just noticed when doing a round 2d contour e.g 10mm wide with a 6mm endmill on the second pass it changes direction. Do you know why it does this and how to change it?
[09:50:41] <archivist> I should get the bot to parse any xxx users here and get it to replay ask the real question
[09:50:59] <norias> trentster: so this is really a CAM question?
[09:51:19] <norias> I'd have to see the model to really answer this
[09:51:27] <norias> screenshot it
[09:51:58] <trentster> http://monosnap.com/image/aYcidJNq4hgTpddsppKNukB6xjcJfs
[09:52:34] <trentster> norias: yes a cam question
[09:52:57] <trentster> archivist: was that comment for directed at me?
[09:52:59] <greg___> it's just cutting in the same direction
[09:53:12] <greg___> one is ouside the path the other inside
[09:53:38] <norias> that's the most reasonable thing I can see
[09:54:02] <greg___> so if you've chosen to climb on all passes it has to reverse direction to do that on the other side
[09:54:06] <trentster> greg___: so is that normal? the only comparison I have is to cambam which does not do that it steps over and then continues in the same direction
[09:54:14] <archivist> it is conventional milling in both cases
[09:54:23] <norias> did you ask it for multiple passes?
[09:54:32] <greg___> if you told it to do so yes, normal
[09:55:08] <archivist> conventional/clime will be an option in some cam programs
[09:55:08] <trentster> No, I had to select both bottom contour lines to get it to cut the correct width
[09:55:14] <trentster> screenshot coming
[09:55:15] <archivist> climb
[09:56:26] <greg___> you probably have a choice, climb, conventional or both. the software is just smart enough to know which side the material is on, it's working correctly
[09:56:27] <norias> you selected both lines, so it followed both
[09:56:34] <trentster> http://monosnap.com/image/Wu6HGmKMKGF9SoW1nCIk49qH8DerGd
[09:56:45] <norias> it looks to me like it's climbing
[09:56:55] <trentster> yes its climbing
[09:56:56] <norias> yeah, see, two chains
[09:57:02] <norias> it's doing what you told it to do
[09:57:20] <trentster> So how would I get it to cut the full width with only 1 chain selected?
[09:57:37] <norias> you're doing "contour"
[09:57:40] <norias> which means, a line
[09:57:50] <norias> it doesn't think in widths in countour mode
[09:58:01] <norias> you'd have to do pocket, but that doesn't make sense for this
[09:58:10] <norias> how wide is that groove
[09:58:12] <greg___> that's the way I do it
[09:58:15] <trentster> norias: heh - yes I am sure its doing what I told it to do, I am sure in this instance the operator is the defective one ;-) who is trying to learn
[09:58:17] <norias> and how wide is the tool
[09:58:22] <trentster> 6mm
[09:58:28] <trentster> width is 10mm
[09:58:30] <greg___> why do you wan to change it?
[09:58:40] <norias> so, it'll overlap
[09:58:49] <archivist> it should change direction for best finish
[09:58:49] <norias> other than the entry / exit part here
[09:58:53] <norias> it looks fine to me
[09:59:05] <trentster> I don't specifically want to change it, just noticed the behaviour is different to cambam, which is what I have been using.
[09:59:15] <norias> well, cambam is probably terrible
[09:59:16] <norias> so
[09:59:19] <norias> :)
[09:59:30] <norias> this is reasonable behavior for CAM
[09:59:31] <greg___> videos of cambam baths look terrible to me
[09:59:34] <trentster> heh - yeah
[09:59:46] <greg___> not just reasonable but proper
[10:00:24] <norias> so, i feel i've learned
[10:00:30] <norias> that the real trick about CAM is
[10:00:35] <norias> knowing how to do it right by hand
[10:00:44] <norias> but being too lazy to write all those lines of g-code
[10:00:50] <greg___> what you saw with cambam results in climb milling on one side and conventional on the other
[10:00:50] <archivist> I have spoken to the cambam author, seems a nice person, but his machine did throw a cutter around his machine because he bit off more than he could
[10:01:12] <trentster> this is cambam in comparison
[10:01:14] <trentster> http://monosnap.com/image/bsOBU8tiF4DNCs12zfKEWUMPpgcQDb
[10:01:45] <trentster> I actually only have 1 polyline in cambam and just select it and tell it how wide to cut.
[10:01:50] <greg___> cambam is great, I'm sure, for the price.
[10:01:50] <trentster> different logic I guess
[10:01:57] <norias> you...
[10:02:05] <norias> you could get the same result here
[10:02:11] <norias> just select the inner profile
[10:02:19] <norias> and do it in two steps
[10:02:31] <norias> some of this depends on material, too
[10:02:45] <norias> no matter what that first cut is going to be a slotting operations
[10:02:55] <trentster> archivist: I really like fusion360 thats why I am putting in the time to learn it - cambam is ok to test out stuff but have not used it beyond the trial period
[10:03:00] <norias> so, it may make sense to go down the middle
[10:03:08] <norias> and clean up both sides of the slot
[10:03:15] <norias> material / tool etc
[10:03:18] <Tom_itx> yeah if you want it real accurate do the middle and clean up both sides
[10:03:22] <greg___> right, slot then finissh the sides
[10:03:32] <norias> but if it's plastic and not critical
[10:03:36] <norias> etc...
[10:03:40] <trentster> ok, let me figure out how to do that
[10:03:44] <greg___> do ti anyway
[10:03:54] <norias> time
[10:04:05] <norias> eh.
[10:04:06] <trentster> in this case its wood, but I mainly am machining aluminium. This is just a lid for cyclone extractor I made
[10:04:10] <greg___> what time?
[10:05:11] <trentster> norias: can you show me a screenshot of how to specify down the middle then do the sides?
[10:05:25] <greg___> saving time comes after you know what to expect from your CAM. then you can avoid cutting air.
[10:06:35] <norias> fair
[10:06:49] <Tom_itx> you would cut 2mm per side, not air
[10:06:58] <greg___> I'd pick one edge and leave enough stock to put the cutter near the middle
[10:07:19] <greg___> then profile each edge
[10:07:57] <greg___> OK, so you save one pass if finish truly doesn't matter
[10:08:23] <norias> i mean, it's going down the rabbit hole, i recognize
[10:08:33] <norias> but, yeah, save a pass
[10:08:38] <norias> put it in the bank
[10:08:40] <norias> invest it
[10:08:43] <norias> might pay off
[10:08:57] <norias> also, work hardening materials
[10:08:58] <trentster> ok - thanks for all the suggestions - time to crack knuckles and get testing.
[10:09:00] <norias> but not this case
[10:09:06] <Tom_itx> if you're worried about time use a 10mm bit
[10:09:18] <norias> amen
[10:09:46] <trentster> I aint worried about time, plus I dont own a 10mm bit, my spindle is er11 - max 1/4 inch
[10:10:40] <greg___> for wood I'd just run a sinlge pass one each edge. I think metal 99% of the time
[10:11:31] <norias> dang
[10:11:35] <norias> i'm odd, i know this
[10:11:44] <norias> but i get disappointed when musicians i enjoy
[10:11:49] <norias> cuss in their lyrics
[10:11:58] <trentster> greg___: thanks for the tip, it makes sense to do the pass down the middle and then finish off each side, I suppose there is less chance of bit deflection that way.
[10:12:21] <trentster> when machining metal I mean
[10:12:29] <norias> pros and cons
[10:12:41] <norias> if you don't leave enough stock to clean up
[10:12:42] <greg___> well it gives you the same width of cut for subsequent passes, all depends on what your machine can actually handle.
[10:12:46] <norias> some tooling doesn't like it
[10:13:18] <norias> i've had tooling that cut like crap at .005" width of cut
[10:13:33] <norias> but was dead on with .200"
[10:13:49] <Tom_itx> even at different feed / speed?
[10:14:02] <Tom_itx> you may have found it's harmonic
[10:14:09] <norias> good point, but, yeah... largely
[10:14:37] <norias> no, some tooling really seems to have a min. doc
[10:14:43] <norias> er, woc
[10:14:51] <norias> whatever term you want to use
[10:14:55] <Tom_itx> cheap shit does
[10:15:00] <greg___> insert mills?
[10:15:01] <norias> lol
[10:15:15] <norias> think about the edge dressing on some inserts
[10:15:28] <norias> that's going to effectively dictate a min. depth of cut
[10:15:44] <norias> it'd be basically... off the top of my head
[10:15:46] <greg___> right, more edge radius means you needs more depth
[10:16:00] <norias> the edge and angle of attack
[10:16:27] <greg___> right, but that's why the supplier has specs
[10:16:33] <norias> deforms but doesn't fail the material
[10:18:33] <_methods> you always need to take at least the radius of the insert in cut depth and width
[10:18:46] <archivist> dont forget machine flex and endmill bending due to cutting force, reasons why you dont take it all out in one
[10:19:18] <norias> archivist: i disagree. you can, just gotta know what you're doing
[10:19:31] <norias> but i see the common error in the learning phases
[10:19:41] <norias> of assuming there isn't a minimum cut width
[10:20:13] <norias> and assuming that if the tool cuts on at a roughing cut
[10:20:22] <archivist> you cannot get the highest accuracy full width
[10:20:24] <norias> that the finish cut is going to be right on
[10:22:52] <greg___> _methods which radius
[10:23:05] <Tom_itx> for sake of argument i agree with archivist however we're looking at a wood lid here
[10:24:24] <archivist> worst problem is clogging the tool with wood
[10:24:27] <Tom_itx> and if you put it on a cmm chances are good you would see a change in the 4 quadrants
[10:27:21] <greg___> making good parts means knowing how to meet the tolerances specified.
[10:29:29] <archivist> those +-0 tolerances are "interesting"
[10:29:54] <archivist> used to tell a certain person off for that habit
[10:30:14] <greg___> trentster are you putting a dust deputy on that?
[10:39:02] <FinboySlick> https://www.youtube.com/watch?v=MOXQo7nURs0 <--- blown away.
[10:39:17] <FinboySlick> It's so simple and beautiful.
[10:39:58] * archivist reboots firefox to watch that
[10:40:27] <FinboySlick> archivist: It's nothing quite new.
[10:46:07] <archivist> FinboySlick, been searching ebay last couple of days for ikea shelves, run out of space error
[10:49:44] <greg___> I'd like to move for the same reason
[11:01:44] <Loetmichel> archivist: thats what woodworking macheines are for ;)
[11:02:10] <archivist> !....effort
[11:02:33] <Loetmichel> but fit to riom ;)
[11:02:46] <archivist> just need a hammer with ikea
[11:03:28] <tjtr33> fenn hello this is Tom Powderly from the Mazak retrofit way back. good to hear from you
[11:05:20] <archivist> Loetmichel, I have some walls with homebrew shelves but they tend to be less useful than the free standing bookcases
[11:05:57] <archivist> Loetmichel, a map for a room http://www.collection.archivist.info/shelfview.php?src=artitle&locid=595
[11:07:56] <tjtr33> justpink heres a bigass edm, just left Canada doing this http://imagebin.ca/v/28xO3hwHNTm4 http://imagebin.ca/v/28xNkyUJF9M0
[11:08:21] <tjtr33> 300 amps 2.5meters in X travel all automotive molds
[11:10:03] <archivist> those large blocks look useful
[11:10:51] <tjtr33> 2-4-6s someplaces have 1-2-3s that are 1ft 2ft 3ft :)
[11:11:06] <CaptHindsight> tjtr33: when you traveled to Canada did you bring tools or use theirs?
[11:11:25] <tjtr33> oh yeah well talk about that in public ;)
[11:11:39] <CaptHindsight> heh
[11:14:29] <tjtr33> off to do laundry, bye
[11:18:16] <CaptHindsight> http://blog.upverter.com/post/109594392482 "This morning, our community has publicly shared over 32,000 open source hardware designs with the world."
[11:21:37] <CaptHindsight> reminds me of the Electronics Book Club in the 70's that featured titles such as "1001 Schematics" some useful
[11:29:39] <archivist> looks like you have to join something to actually get anything
[11:45:18] <CaptHindsight> https://upverter.com/awkimballjr/2a1b57e3dddacb91/GetDibs/ I click on one of the first designs and all the files seem to be there
[11:45:44] <Loetmichel> meh, DHL again. bought a used laptop from a big leasing-reseller. today the tracking said "delivered"... no yellow truck at the company all day. Called them: Oh, thas an error from the delivery guy. i can se he sent it back because of "insufficient packaging"...
[11:46:20] <pcw_home> sounds like they tenderized it...
[11:46:35] <Loetmichel> nice one... thats a big company. they send the latops in big triple wave corruigated boxes with loads of bubblewrap inside... how did they manage to damage THAT?
[11:46:59] <CaptHindsight> so DHL has poor service even Germany? they used to be so good
[11:47:27] <pcw_home> Weve had stuff from Fedex that looks like it was dropped 6 feet onto concrete
[11:47:56] <pcw_home> Isnt DHL a Fedex subsidiary now?
[11:49:16] <pcw_home> They are taking package damage classes from Fedex
[11:50:09] <tjtr33> hah the dhl delivery in CA took a week to 'clear customs' . well my mind makes up reasons when i dont really know what happened.
[11:50:47] <roycroft> it seems there is a significant amount of discussion on this channel about carriers damaging parcels
[11:50:48] <CaptHindsight> international customs is like a magic-8 ball
[11:50:56] <pcw_home> Why are there so many customs problems between CA and US? its always a problem
[11:51:03] <roycroft> i receive quite a few parcels personally, and we receive several per day at the office
[11:51:16] <roycroft> and i cannot recall the last time i or the office received anything that was damaged by the carrier
[11:51:37] <pcw_home> I sure can
[11:51:41] <roycroft> we use usps, dhl, ups, fedex, and freight companies
[11:51:41] <CaptHindsight> I've sent 2 identical packages to two different cities and see completely different behaviors
[11:52:09] <CaptHindsight> one gets taxed and delayed 3 weeks, the other shows up no tax in 6 days
[11:52:09] <tjtr33> i arrived on time and worked on other crap while waiting. it was supoosed to be Mon mornn, but it was Fri nite 5pm delivered. THEN i got to start
[11:52:28] <roycroft> i've seen delays more often than i would like, but damage is extremely rare
[11:53:13] <pcw_home> Not rare enough, we see significant damage about once a month
[11:53:21] <tjtr33> well I built the crate, they'd really have to be obviously mean to damage my goods
[11:53:36] <CaptHindsight> I've had parcles damaged so bad they didn't even return them, just immediately notified me that it was covered by insurance and my claim was already processed
[11:53:44] <Loetmichel> the company i work for once sent 2 24 pin rugged printers (30+g shockproof) to a customer via UPS
[11:54:25] <Loetmichel> the managed ot damage BOTH printers, 2mm thick aluminium enclosure toirsioned beyond repair... and inside the printer chassis broken in severy places
[11:54:48] <pcw_home> so much so the we dont ship kits or assembled board lots by Fedex or UPS anymore,
[11:54:49] <pcw_home> just too likely to have 50 out of 500 boards ruined by being dropped from high altitude
[11:54:59] <skunkworks> we have pretty good luck with shipments too.. (and we buy a lot of monitors and such)
[11:55:03] <Loetmichel> the very well bubblewrapped printers were a total writeoff... and the packing boxed hadnt as much as a scratch
[11:55:12] <roycroft> it would be intersting to embed ruggidized "body cams" with long battery life, lots of memory, and motion-activation in parcels and document their handling
[11:55:27] <Loetmichel> the must have fallen out of the loading door of a 747 or something, exactly parallel on one side of the package
[11:55:38] <CaptHindsight> roycroft: there are some youtube vids of that
[11:55:52] <roycroft> i should have assumed so, capthindsight
[11:56:04] <roycroft> there are youtube videos of almost everything, including things that do not exist
[11:56:06] <pcw_home> Thats the kind of thing we have seen (or fallen off a high conveyor belt)
[11:56:09] <archivist> I remember watching the youtube loader vid that did the rounds
[12:00:11] <furrywolf> I got an air compressor shipped UPS that had been driven over. complete with a truck tire tread marks.
[12:00:31] <furrywolf> the compressor itself survived, but all accessories (motor capacitor, popoff valve, etc) smashed flat.
[12:01:15] <furrywolf> I've watched UPS unload their plane by simply pushing stuff out the cargo door. I've also watched them unload a truck the same way. seems to be standard practice.
[12:01:34] <archivist> furrywolf, have you had the training to damage stuff :)
[12:02:09] <furrywolf> no. I work for a responsible company. We deliver things NOT broken.
[12:02:37] <archivist> delivery I did this morning, the customer wanted us to put it over a wall!
[12:02:43] <Loetmichel> furrywolf: that still exists?
[12:03:07] <archivist> we escaped leaving it undamaged and this side of the wall
[12:03:11] <Loetmichel> i thought there were only "got you money, dont care about your stuff" companys out there
[12:07:12] <furrywolf> UPS seems to be trying hard to lose something I ordered last week... so far it was "We left the package in our facility. This may cause a delay. We will deliver as quickly as possible. " for a while, now it's in transit but hasn't updated for three days...
[12:07:31] <CaptHindsight> odd : Anyone can fork open source designs to experiment on their own with a free community edition account, or join our 14-day trial for commercial use.
[12:08:01] <tjtr33> ? that upverter thing?
[12:08:14] <CaptHindsight> yeah, commercial use of what? the open design files?
[12:08:35] <_methods> fork that
[12:08:47] <CaptHindsight> https://upverter.com/pricing/
[12:09:07] <CaptHindsight> they have a crappy web editor that you can pay to use
[12:09:22] <furrywolf> I really should stick to my policy of never ordering from anywhere that ships UPS. but it's hard, because like this place, they often just say "Standard shipping" or such crap, without specifying they're going to ship it UPS.
[12:10:40] <_methods> i think i'll just stick to kicad or eagle
[12:12:58] <tjtr33> Orcad on DosBox :)
[12:13:04] <furrywolf> To quote the shipping policy of the place I ordered from... "Your item may ship UPS Ground, Smartpost, FedEx or USPS regardless of the method displayed during your checkout. "
[12:13:29] <roycroft> ups delivers to me on time and without incident almost every time
[12:13:38] <roycroft> i must live in a different world than some folks here
[12:13:44] <furrywolf> how the hell can you avoid UPS when places will ship UPS even after they tell you they're shipping USPS?!
[12:14:11] <tjtr33> haha there was a diner up in Michigan. The Little Red Lunchbox. motto was ' Order what you like, eat what you get"
[12:14:30] <tjtr33> they only had 1 thing on menu any day
[12:15:22] <archivist> the leftovers from the day before!
[12:16:08] <furrywolf> there used to be an indian restaurant here where the owner/chef liked experimenting... since he knew I liked a variety of foods, sometimes I'd walk in, and rather than getting a menu, he'd walk out with a plate and go "Today you try this!".
[12:17:59] <tjtr33> like dave lister from red dwarf, anything vindaloo
[12:18:26] <furrywolf> suicide hot, fire extinguisher on standby?
[12:18:55] <furrywolf> the best of the unexpected dishes was goat leg curry, on the leg...
[12:19:09] <furrywolf> the owner was pakistani, so he'd also make beef dishes, which I like.
[12:20:12] <furrywolf> not on the menu, but he'd make them randomly, and for himself.
[12:22:56] <furrywolf> I miss that place. :(
[12:24:09] <furrywolf> the owner had to go back to pakistan to marry off his kids, and said he'd probably stay there... sold his restaurant and I haven't seen him since. the new owners sucked, the food was crap, then they sold it again, to owners that sucked, and made crap food, then they sold it again, and thew new food is mediocre at best...
[12:51:10] <CaptHindsight> driver was told to keep an eye on this box https://youtu.be/lM3SRG7D21Y?t=1m37s

[13:01:40] <_methods> i order stuff and totally forget i ordered it
[13:01:46] <_methods> then boom xmas in june
[13:02:29] <archivist> all the other bits for this dream have arrived....
[13:03:20] <archivist> so what over travel should I design into a probe

[13:12:31] <_methods> oh lord
[13:12:34] <CaptHindsight> another allwinner ARM PC
[13:13:05] <_methods> first true android pc lol
[13:13:57] <CaptHindsight> someone pointed it out to me yesterday, the resizeable windows in Android might be the only new thing about it
[13:14:11] <CaptHindsight> but then someone said that feature is in v5
[13:14:18] <_methods> looks like any other a53
[13:14:26] <_methods> just in a black case lol
[13:15:15] <CaptHindsight> and weren't there USB dongle sized ARM PC a couple of years ago for ~$30
[13:15:23] <_methods> yeah there still are

[13:16:53] <CaptHindsight> ok so the one on Kickstarter is just lower cost or the accessories are extra
[13:17:06] <_methods> yeah
[13:17:28] <CaptHindsight> like the $9 arm module that cost $35 if you want it to do anything

[13:21:29] <_methods> yeah
[13:21:36] <_methods> i can only handle so much kickstarter
[13:21:47] <_methods> especially with donald trump at #1 for gop right now
[13:21:54] <_methods> my brain can only handle so much
[13:22:11] <archivist> all the crackpot ideas now have a funding avenue
[13:22:18] <_methods> i keep waiting for the water guys to show up and replace all our coolers with brawndo
[13:23:14] <CaptHindsight> but it's got electrolytes
[13:23:19] <_methods> heheh
[13:40:21] <greg___> lols i've not heard of brawndo before ahd to look it up
[13:45:20] <CaptHindsight> you have to watch the movie
[13:55:37] <Tom_itx> elmer fudd for pres
[14:00:32] <_methods> brawndo it's got what plants crave lol
[14:56:31] <os1r1s> _methods: +1
[15:03:42] <_methods> hehe
[15:03:51] <_methods> love that movie
[15:05:15] <os1r1s> _methods: I just watched that again about 3 weeks back
[15:05:22] <os1r1s> _methods: Its great amusement
[15:05:49] <_methods> until they show up at your work to install the brawndo machines lol
[15:06:16] <os1r1s> But it has electrolytes.
[15:06:21] <_methods> hehe
[15:06:24] <CaptHindsight> _methods: http://www.themarysue.com/brawndo-drinking-fountain-idiocracy/
[15:06:26] <os1r1s> Its what plants crave
[15:06:31] <_methods> yeah i saw that fountain
[15:06:37] <_methods> i need to make one of those
[15:06:49] <os1r1s> CaptHindsight: That's funny
[15:06:58] <CaptHindsight> Brawndo ____ Toilet Water
[15:07:19] <_methods> you mean like water out of a toilet?
[15:15:32] <XXCoder> tiolet water
[15:15:34] <XXCoder> heh
[15:15:41] <XXCoder> that movie was funny
[15:18:25] <CaptHindsight> I'd really like to see the first or a directors cut of that since the studio killed the film
[15:19:15] <CaptHindsight> I read that they also cut lots of scenes and heavily edited it to tone it down
[15:22:34] <XXCoder> interesting
[15:29:57] <_methods> isn't there an uncut version?
[15:30:29] <XXCoder> longer, bigger and uncut
[15:30:38] <XXCoder> maybe? heh
[15:32:11] <_methods> i'm not usually into prophecy movies but i love idiocracy lol
[15:33:41] <XXCoder> "South Park: All Hell Breaks Loose." was orginial title for South Park: Bigger, Longer and Uncut. Sadly censors didnt approve of former and didnt realize latter is worse LOL
[16:25:42] <Deejay> gn8
[16:42:38] <PetefromTn_> I must say that the GOOD anodized parts I was able to do looked really good.....the finish they got at the pro anodizing shop was freaking amazing!! LOL
[16:43:38] <XXCoder> PetefromTn_: making progress eh :)
[16:43:46] <PetefromTn_> Nope
[16:43:55] <PetefromTn_> parts are done and shipped!!
[16:44:04] <XXCoder> way to go!
[16:44:18] <XXCoder> im STILL waiting for my spindle lol
[16:44:19] <PetefromTn_> and I was amazed at how PRO they looked when I picked them up from the anodizers shop
[16:44:41] <PetefromTn_> it sure was nice to see my own parts looking awesome and clean and smooth and BLACK.
[16:44:45] <XXCoder> bit confused
[16:44:53] <PetefromTn_> Hopefully the customer feels the same way.
[16:45:04] <XXCoder> isnt you anodize em? or was it a failure so you dropped it off there?
[16:45:06] <CaptHindsight> how many spots were touched up with a magic marker?
[16:45:15] <PetefromTn_> heh
[16:45:22] <PetefromTn_> they looked REALLY good man
[16:45:22] <XXCoder> lol
[16:45:33] <XXCoder> with magic marker? ;)
[16:45:38] <PetefromTn_> I must say those guys are good
[16:45:51] <PetefromTn_> If I had more time I am sure I could have gotten them all done myself
[16:45:59] <PetefromTn_> but I just simply ran out of time
[16:46:04] <CaptHindsight> yes, they touch up small marks in black anodize with a black marker
[16:46:25] <PetefromTn_> and with the little issues I was having I did not have time to mess with it
[16:46:40] <XXCoder> I guess can learn with scrap
[16:46:42] <PetefromTn_> Honestly I am quite pleased I did get them done professionally because now I have a resource
[16:47:02] <XXCoder> so next time can do yourself and cheaper
[16:47:11] <PetefromTn_> their price was not too terrible even considering they had to FIX my bad ones
[16:47:50] <PetefromTn_> they even packed them up nicely individually and boxed them up for me so I just had to check them out and put the hardware in the package and tape it up.
[16:47:54] <XXCoder> in end its better to deliver in time than be late and perfect by yourself
[16:48:02] <PetefromTn_> exactly
[16:48:30] <PetefromTn_> as I said I wil STILL be messing with the anodizing and now I have a way to do that which I did not before
[16:48:46] <PetefromTn_> and for small number jobs or custom stuff I will play with it here.
[16:48:59] <PetefromTn_> anything more than say 30 parts and it is going to knoxvegas for sure.
[16:49:18] <PetefromTn_> they saved my bacon!
[16:49:34] <XXCoder> dammit!
[16:49:42] <XXCoder> aliexpress login is broken
[16:50:12] <XXCoder> they dont know concept of testing with different browsers.

[16:50:20] <XXCoder> and apparently test server
[16:50:49] <XXCoder> yay my power supply is arriving tomorrow

[16:58:14] <XXCoder> with inside sharp corners even
[16:58:26] <XXCoder> I guess its REALLY loud
[16:58:29] <PetefromTn_> yeah they had some at the shop I used to work in...

[16:59:31] <XXCoder> I guess it hit it lol
[16:59:42] <_methods> yeah i'm always lookin at auctions for rotary broach sets

[17:12:49] <XXCoder> any of you guys use press to make holes?
[17:13:03] <zeeshan> all the time!
[17:13:32] <XXCoder> lol ok. just saw video tjat uses 100 ton press
[17:13:37] <XXCoder> he made it for just $100
[17:13:59] <zeeshan> i wouldn't watch that idiot
[17:14:07] <zeeshan> aka arduinovsevil
[17:14:10] <XXCoder> not as insane as that 1,000 ton press lol
[17:14:34] <XXCoder> that ones for sale for few million if you want one LOL
[17:14:45] <XXCoder> Ave yeah
[17:14:51] <XXCoder> he uses gloves with lathe

[17:28:07] <XXCoder> well gonna go out do stuff
[17:36:53] <justpink> hi
[17:38:41] <justpink> someone here have some experience with graphite machining ?
[17:41:42] <Tom_itx> graphite is a lubricant
[17:42:10] <justpink> I know..
[17:43:37] <justpink> what the rpm and the feed rate for it?
[17:44:41] <Tom_itx> http://www.semcocarbon.com/semco-carbon-blog/five-keys-to-success-when-machining-graphite
[17:46:03] <Tom_itx> Machining graphite on a CNC machine that has not been specifically modified to handle the graphite dust can lead to expensive damage and potentially void a warranty.
[17:53:23] <justpink> I'm using graphite dust on the rails
[18:26:47] <JT-Shop> dang installing this servo drive was made so painful by lack of communication it ain't funny
[18:36:37] <JT-Shop> they converted the old drive program to the new drive but used the old motor parameters... an 8 pole motor don't like being treated like a 6 pole motor
[18:41:03] <justpink> hi
[18:41:38] <justpink> someone know how about let housing that fit on a panel?
[18:42:12] <justpink> LED*
[18:42:46] <justpink> I want somting that I can put my own LED and it has a way to keep the legs from bending
[18:44:22] <XXCoder> justpink: wild guess some high rpm
[18:44:42] <justpink> 40-60K..
[18:45:05] <justpink> you know abot the LED thing?
[18:45:31] <XXCoder> I know theres few stuff that secures led in housing that can then be bolted on
[18:46:05] <XXCoder> is that what you mean?
[18:46:21] <XXCoder> http://assmann.us/images/A-LED8-1AAAS-MR7-1-R.jpg
[18:47:04] <justpink> XXCoder: yes, this is what I mean.. but i want some securty for the pins.
[18:47:21] <XXCoder> wouldnt pins be inside?
[18:47:28] <XXCoder> not sure what you mean by security
[18:48:48] <justpink> just to make it more resistant to bending..
[18:49:18] <XXCoder> I guess you can always use strain relief before that thing
[18:51:02] <justpink> I cant use the LEDs that alraty come with the housing because i need it to 5, 12, 24, 72, 110 volts
[18:51:23] <justpink> and they come only for 12V
[18:51:40] <justpink> http://www.ebay.com/itm/5-22mm-AC-DC-12V-Mixed-5-Color-Red-Green-Blue-Yellow-White-LED-Indicator-Light/130869736819?_trksid=p2047675.c100010.m2109&_trkparms=aid%3D555012%26algo%3DPW.MBE%26ao%3D2%26asc%3D32297%26meid%3D729df237d59d49549620f53dc7424a25%26pid%3D100010%26rk%3D3%26rkt%3D24%26sd%3D271854780243
[18:51:41] <XXCoder> I suppose you can build em?
[18:52:35] <justpink> em?
[18:52:58] <XXCoder> lazy way to say them
[18:53:13] <JT-Shop> lol
[18:54:55] <justpink> nice..
[18:56:45] <justpink> I need the oled buttones
[18:57:02] <XXCoder> display type or?
[18:57:16] <XXCoder> because I remember that keyboard that has displays each button lol
[18:57:26] <XXCoder> and later version that has eink screens each keyboard
[18:57:29] <XXCoder> button
[18:57:59] <justpink> http://www.digikey.com/videos/en/vp/1646398617001?WT.pn_sku=360-2329-ND&WT.z_part_id=1948850&WT.z_video_source=Part_Detail
[18:58:57] <XXCoder> drat
[18:59:05] <justpink> I will need just 19 of them..
[18:59:07] <XXCoder> flash is disabled, I dont plan to enable it
[18:59:21] <justpink> why>
[18:59:23] <justpink> ??
[18:59:33] <XXCoder> exploits keeps chopping up
[18:59:37] <XXCoder> flash is so hackable
[19:00:04] <XXCoder> thankfully youtube has html5 support
[19:00:17] <justpink> It's digikey...
[19:00:55] <justpink> http://www.digikey.com/product-search/en/optoelectronics/display-modules-lcd-oled-graphic/524918?k=oled%20|%20smartdisplay&vendor=360
[19:01:02] <justpink> just photos..
[19:01:59] <XXCoder> small displays interesting
[19:02:11] <XXCoder> do you configure linuxcnc to use em or?
[19:02:28] <XXCoder> dang so expensive
[19:02:31] <justpink> I don't know..
[19:03:02] <justpink> just 834 for the high res one..
[19:03:08] <justpink> 83$*
[19:03:19] <XXCoder> its cheaper to buy nook replacement screen and hak it to show all 9 info
[19:04:15] <XXCoder> http://essentialscrap.com/eink/
[19:05:21] <justpink> very nice!!
[19:05:38] <XXCoder> wont work if speed is important though
[19:06:17] <justpink> it is.important..
[19:06:30] <XXCoder> what fps do you think you need?
[19:06:35] <justpink> and I'm really need red and green indicators..
[19:08:32] <XXCoder> regular lcd screen is still cheaper
[19:08:44] <XXCoder> because dang 9 * $86
[19:08:53] <XXCoder> thats over 700
[19:09:42] <XXCoder> or close to total I spent on my cnc router, including stuff that turned out to be useless
[19:10:16] <justpink> I need just 19..
[19:10:28] <XXCoder> 19 * $86?
[19:10:33] <justpink> 83
[19:10:45] <XXCoder> yeah still very big number :)
[19:10:52] <justpink> 1577
[19:11:31] <XXCoder> honestly best way is just one standard lcd montior
[19:11:33] <justpink> I can buy one more G0704 +
[19:11:44] <XXCoder> and leds for that important indictors
[19:12:02] <justpink> or to go with the oled for the arduino..
[19:12:21] <justpink> they cost about 5$
[19:13:03] <XXCoder> yeah seems to be better option
[19:13:31] <XXCoder> theres software to use old nook simple touch as montior for arduino lol
[19:13:33] <justpink> http://www.ebay.com/itm/Blue-0-96-IIC-I2C-Serial-128x64-OLED-LCD-LED-Display-Module-Fr-Arduino-STM32-51-/141418458253?pt=LH_DefaultDomain_0&hash=item20ed326c8d
[19:13:57] <XXCoder> wow nice
[19:14:08] <XXCoder> lots fun possibilities there
[19:14:19] <XXCoder> too bad im not very good with soldering and hardware
[19:14:25] <justpink> thist thing with nano + Push button + = less than 10$
[19:14:44] <justpink> it's very easy..
[19:15:01] <justpink> I'm with very long nails can do it very easy..
[19:15:17] <justpink> I'm shure you can do it...
[19:15:36] <XXCoder> guess so just need real use before buy :)
[19:15:40] <justpink> I have the radio shack gas power soldering iron.
[19:15:58] <justpink> and It's work just fine,,
[19:17:14] <XXCoder> yeah I has butine gas solder
[19:17:17] <XXCoder> pretty nice
[19:17:22] <XXCoder> if bit hard to start lo
[19:17:48] <justpink> just practice..
[19:19:13] <XXCoder> yea I rather run cnc machines than solder lol
[19:20:57] <justpink> you have the parts?
[19:21:25] <XXCoder> well I have complete machine
[19:21:27] <XXCoder> mostly
[19:21:36] <XXCoder> still waiting on spindle and its power source
[19:25:53] <justpink> this must bee soo frustrating to see the machine working but without the spindle
[19:27:03] <XXCoder> yeah lol
[19:59:53] <justpink> how I know what size of heat shrink I need?
[20:00:13] <XXCoder> isnt it has size printed on it?
[20:00:26] <archivist> get an assortment
[20:00:26] <justpink> I don't know..
[20:00:45] <justpink> I need it for isolation the LEDs pins
[20:00:45] <archivist> use the smallest for each job
[20:01:02] <XXCoder> smallest possible you mean lol
[20:01:15] <justpink> It's need to be very small diameter
[20:01:20] <archivist> that fits!
[20:01:52] <justpink> but what is the "key words"
[20:02:38] <archivist> http://www.ebay.co.uk/itm/Assorted-Box-of-Black-Heatshrink-2-1-1-6-19-1mm-40mm-long-Qty-360-/252017479156
[20:03:27] <archivist> local discount store has them occasionally
[20:04:17] <archivist> that particular ebay listing is expensive but the first I found
[20:05:44] <archivist> search was assortment heatshrink
[20:05:57] <justpink> I can
[20:06:19] <justpink> I can't understand it it's the inner ot outer diameter,,
[20:06:28] <XXCoder> just watched youtube of someone turning old wrench into sharp knife
[20:06:33] <XXCoder> okay. :P
[20:06:41] <XXCoder> looks kinda cool but...
[20:06:55] <malcom2073> Ahh I love craigslist scammers
[20:07:04] <malcom2073> Sad that most of the responses I get are from them :/
[20:25:44] <justpink> www.ebay.com/itm/3mm-10ct-LED-Light-Holder-with-Chrome-Housing-/140822577465?pt=LH_DefaultDomain_0&hash=item20c9ae0139
[20:26:10] <justpink> I can't find the data sheet of it..
[20:26:12] <XXCoder> 10 for 3 bucks cheap
[20:26:23] <XXCoder> that looks lik standard led holder
[20:26:55] <XXCoder> it says 10 mm, 8 mm and 5 mm is aviliabkle
[20:27:42] <justpink> yes.. but I want something with part number so I will be able to order the same one after a while
[20:29:23] <XXCoder> indeed
[20:29:33] <XXCoder> some stuff is just standard though
[20:31:46] <justpink> http://www.abb.com/productdetails/ABB2CSG533050R3001
[20:32:02] <justpink> This is the stuff that I'm really want..
[20:33:02] <justpink> I can't find any one that sell them :(
[20:35:55] <justpink> not what i'm looking for but still very cool
[20:35:56] <justpink> http://www.galco.com/buy/Powerex/T620123004DN
[20:39:55] <justpink> http://www.esinuclear.com/Pictures/Annunciator.jpg
[20:40:28] <XXCoder> lol thats somewhat old
[20:50:10] <XXCoder> pretty amazing. too bad I ont have lathe nor wood skills lol http://woodgears.ca/reader/pekka/segmented_bowl.html
[20:54:12] <justpink> I dont like wood..
[20:54:25] <XXCoder> lol
[20:56:04] <justpink> I wouldn't trust him.. he use google SketchUp
[20:56:15] <justpink> http://woodgears.ca/reader/pekka/mitersaw.html
[20:56:16] <XXCoder> why
[20:56:36] <justpink> SketchUp vs solidworks ... mmm
[20:57:35] <justpink> how many factories use SketchUp?
[20:57:41] <XXCoder> unknown
[20:57:48] <XXCoder> I dont even know what company I work for use.
[20:58:01] <XXCoder> they do use preditorcnc for gcode edditing but besides that dunno
[21:00:11] <justpink> you like the preditorcnc ?
[21:00:28] <XXCoder> dunno it seems ok
[21:00:34] <XXCoder> I mispelled it
[21:00:55] <XXCoder> http://www.predator-software.com/
[21:01:54] <XXCoder> no linux version bah
[21:02:35] <justpink> what is the cost?
[21:02:38] <malcom2073> Yeah, but not everyone can afford solidworks heh
[21:02:52] <zeeshan> lol at ketchup
[21:03:37] <XXCoder> justpink: I cant afford it since it doesn't say
[21:03:42] <zeeshan> solidworks is cheap
[21:03:47] <zeeshan> especially if you're a veteran
[21:03:48] <zeeshan> its only $20
[21:04:00] <XXCoder> zeeshan: can you send me off to war for a day?
[21:04:04] <zeeshan> :D
[21:04:04] <XXCoder> so I canbe a vet :P
[21:04:26] <XXCoder> being deaf means I will never be one lol
[21:04:34] <XXCoder> so solidworks is expensive for me
[21:05:09] <zeeshan> student edition which is full y featured
[21:05:12] <zeeshan> is $150
[21:05:23] <XXCoder> yeah I want to sell stuff :)
[21:05:41] <justpink> i get it installed on a computer
[21:05:43] <XXCoder> honestly when starting I wont need any cad package
[21:05:44] <zeeshan> actually, dont use solidworks
[21:05:46] <zeeshan> its garbage
[21:05:51] <zeeshan> use sketchup
[21:05:53] <zeeshan> or freecad!
[21:06:00] <zeeshan> or even that autodesk thing
[21:06:10] <XXCoder> I'll mostly just use linux cnc built in support profiling thing
[21:06:37] <justpink> try solidworks
[21:06:54] <trentster> why not use fusion360 as a solidworks alternative?
[21:07:25] <trentster> Cad + CAM + free 3 year licence
[21:07:51] <justpink> fusion360 is the cloude based?
[21:08:18] <trentster> its a hybrid desktop and cloud based.
[21:08:29] <trentster> its very cool
[21:08:47] <os1r1s> trentster: Its limited in features
[21:09:02] <os1r1s> trentster: It does ok for free. And I've used it a bit
[21:09:26] <justpink> you can do stuff like wireing?
[21:10:13] <justpink> I'm several years with solidworks.. so I'm wayy deep in to it
[21:10:55] <malcom2073> There's a solidworks like cloud based one now, onshape
[21:11:14] <justpink> there is a safe wat to connect LED to 110V?
[21:11:20] <justpink> way*
[21:11:20] <os1r1s> justpink: For CAD it sucks
[21:11:23] <os1r1s> For cam its ok
[21:11:36] <os1r1s> justpink: I used solidworks for cad as well
[21:11:57] <os1r1s> If you like autodesk inventor, fusion360 will be a light version of that
[21:12:13] <XXCoder> I really liked solvespace
[21:12:22] <justpink> os1r1s: solidworks is just for cad - the cam is addons
[21:12:25] <XXCoder> too bad it dont have enough developers and very slow moving
[21:12:48] <os1r1s> justpink: I know
[21:12:53] <os1r1s> fusion360 does both
[21:12:55] <zeeshan> who needs cam
[21:12:59] <zeeshan> when you got a keyboard and g-code
[21:13:01] <zeeshan> !!!!!!!1
[21:13:40] <justpink> zeeshan: please provide me a g-code for 3d machining :)
[21:14:20] <XXCoder> yes, hemisphere please
[21:14:20] <zeeshan> easy pz
[21:14:24] <XXCoder> from block of alum
[21:15:30] <zeeshan> i need energy go to in garage
[21:15:33] <zeeshan> and start machining
[21:16:30] <justpink> how many joules will kik you up?
[21:21:41] <XXCoder> zeeshan needs 1.21 gigawatts
[21:21:49] <XXCoder> and 88 mph
[21:23:29] <just_pink> go to almost any power plant with almot any car..
[21:23:40] <XXCoder> http://www.iflscience.com/rise-machines-robot-demonstrates-self-awareness-solving-logic-puzzle
[21:24:54] <just_pink> cute
[21:25:10] <XXCoder> and apparently small aspect of AI is figured out
[21:25:14] <XXCoder> self awareness
[21:25:35] <XXCoder> it was not programmed to say it. it figured out
[21:26:29] <XXCoder> its not same sort of self awareness we has but nevertheless it s
[21:28:40] <just_pink> who need kids..
[21:32:38] <toddz_> Is the mailing list down?
[21:49:24] <os1r1s> Tom_itx: Do you use homing on your taig/sherline?
[21:52:01] <just_pink> os1r1s: I'm using
[21:52:15] <os1r1s> just_pink: You have a taig/sherline mill or lathe?
[21:52:26] <just_pink> G0704
[21:52:40] <os1r1s> And you use homing?
[21:52:46] <just_pink> yes
[21:53:36] <just_pink> you mean homing swiches on the machine?
[21:53:46] <os1r1s> just_pink: Do you connect yours on one pin or do you do them separately? I know you can do either. Right now I have them individually. I'm thinking about combining them to save/reuse some pins.
[21:54:10] <just_pink> seperatly
[21:54:20] <os1r1s> Ok
[21:54:28] <just_pink> I have 3 pins in the LPT X Y Z
[21:54:41] <just_pink> ans i have also 3 switches
[21:54:45] <os1r1s> Thats what I'm doing too.
[21:54:57] <os1r1s> You have 3 switches for the other side?
[21:54:58] <just_pink> but 2 wadges on each axis.
[21:55:20] <os1r1s> wadges?
[21:56:07] <just_pink> each axis have 2 wedges and 1 swiche
[21:56:24] <os1r1s> What is a wedge?
[21:56:25] <just_pink> >-------------------|--------------------<
[21:56:44] <just_pink> I can take apic of the system
[21:57:09] <os1r1s> I'd like to see one. I'm curious
[21:58:01] <just_pink> but I' tall you new it is 2 stage system.
[21:58:30] <just_pink> 1 stage for acurate homing and 1 stage go to the Estop loop
[22:03:13] <just_pink> http://i.imgur.com/oGHwLyO.png
[22:03:22] <just_pink> os1r1s: ^
[22:04:25] <os1r1s> Ahh, very interesting. So 1 switch gives you homing plus min/max
[22:04:54] <just_pink> the switch is fixed, and the end you have the wedge
[22:05:10] <just_pink> so one switch per axis
[22:05:23] <os1r1s> That's pretty slick. Not sure I can make that work, but I like it.
[22:07:42] <just_pink> the optics need very tight tolerances the space is 0.1mm between the slot to the interapting plate
[22:09:51] <just_pink> but the repitatitity is way more than I need it's so accurate that the needle at the indicator not move
[22:10:01] <os1r1s> just_pink: I'm trying to figure out how this one works for the sherline lathe ... http://www.cadcamcadcam.com/images/products/detail/lathehome1.JPG
[22:10:55] <just_pink> dont use the mecanical swiches for homing
[22:11:25] <just_pink> I cant understand from the picture what I see
[22:11:43] <os1r1s> just_pink: I use them on my taig now. It looks like yours is mechanical
[22:12:13] <just_pink> the mecanical go to the E-stop loop
[22:12:22] <just_pink> the optic make the homing
[22:12:35] <just_pink> take a pic with wider view
[22:13:33] <os1r1s> Ok
[22:14:24] <just_pink> it is very simple desigen
[22:15:05] <just_pink> If the macanical acurate for you, you can do it veryy easy
[22:16:00] <just_pink> http://i.imgur.com/L8R6s7S.png
[22:16:08] <just_pink> this is the prencipale
[22:16:45] <os1r1s> I get the e-stop loop. But the homing part is what I'm curious about. The optical side
[22:17:11] <just_pink> the optical is same idea
[22:17:32] <os1r1s> What type of switches do you use?
[22:17:56] <just_pink> the cheapest from radio shack.
[22:18:27] <os1r1s> For optical?
[22:18:57] <just_pink> I have no idea it was a pack here.
[22:19:03] <os1r1s> Ahh, ok
[22:20:24] <just_pink> test the mecamical switch that you have
[22:21:29] <just_pink> and see what is the repetitivity that you get.
[22:22:06] <os1r1s> I've been good on the mill
[22:22:19] <os1r1s> Thats what I've been using for years
[22:23:13] <just_pink> just hold it tight with the finger against the table or something and make homing cycle.
[22:23:53] <os1r1s> It works fine. I'm just debating on looping them into one switch
[22:25:24] <just_pink> the radio shack give me about 0.1-0.06 repetitivity this is really bad
[22:25:45] <os1r1s> mm or in?
[22:26:41] <just_pink> mm
[22:27:12] <just_pink> you have T slot on the front of the tiag
[22:27:22] <just_pink> and you have the stopper
[22:27:30] <just_pink> take the stopper out
[22:27:43] <just_pink> put the switch instad
[22:28:00] <os1r1s> I do. I have push button switches already on one side that I use for homing. But I'll look into a wedge system for it
[22:28:03] <just_pink> and on the front T slot put the wedges
[22:28:32] <os1r1s> I need to get my lathe homing first. And I have to finish my tool changer for the taig.
[22:29:45] <just_pink> I want also tool changer but i need to finish the panel first and desigen elctrical power drawbar
[22:30:47] <os1r1s> This is where I'm at with mine. Prototyping parts to be used in the final ... http://gallery.mounicou.com/photos/i-3xS2KR6/0/L/i-3xS2KR6-L.jpg
[22:31:36] <just_pink> it's use R8?
[22:31:41] <os1r1s> No
[22:32:15] <just_pink> what collet it use?
[22:32:20] <os1r1s> With the tool changer I'm using ER11 collets
[22:39:01] <just_pink> how you open the EE11? from the tool changer
[22:39:28] <os1r1s> just_pink: It uses air to actuate a closer
[22:39:50] <just_pink> on ER11???
[22:39:53] <just_pink> how?
[22:40:23] <just_pink> the ER11 close from the bottom
[22:40:42] <os1r1s> just_pink: Its an SK15 holder
[22:40:48] <os1r1s> With an Er11 inside
[22:40:55] <os1r1s> just_pink: https://www.youtube.com/watch?v=UOKeW9JOs_A
[22:42:44] <just_pink> it's soo tiny
[22:42:51] <os1r1s> Yah
[22:43:03] <os1r1s> But I can do 1/4 and 1/8 bits which is all I really need
[22:43:13] <just_pink> you can use fly cutter with that..
[22:43:30] <just_pink> can't*
[22:44:10] <os1r1s> That true. But I don't need them all that often
[22:44:33] <os1r1s> And if I really did I'd just put the other spindle back on
[22:45:14] <just_pink> this is way i want to go direct from the R8
[22:46:03] <os1r1s> just_pink: Sure. R8 isn't an option for me
[22:46:16] <os1r1s> If I were using that mill, I would do that too
[22:46:55] <os1r1s> My mill is upstairs though in my workshop. And I couldn't do that with a G0704
[22:49:08] <furrywolf> speaking of ER collets, my $23 chinese ER20 collet set got in today... quality looks decent, and even though it wasn't mentioned at all on the listing, they came in individual labeled plastic cases.
[22:50:01] <just_pink> os1r1s: you dont have a draw bar?
[22:50:06] <os1r1s> just_pink: No
[22:50:17] <furrywolf> each individual plastic case is, amazingly, labeled in a different random font with different random typos.
[22:51:36] <os1r1s> furrywolf: Thats awesome
[22:51:58] <furrywolf> Size, SIze, S1ze, s1ze. Model, Mode1, ModeL. Accuracy, Accuracv. Material, Materia1. In four different fonts.
[22:53:17] <just_pink> sent a photo

[23:03:25] <furrywolf> uploading will be a while longer...
[23:04:34] <furrywolf> one of these days... :P
[23:05:52] <XXCoder> lol
[23:06:04] <XXCoder> not bad fur
[23:06:20] <XXCoder> almost looks like im commeting on your fur :P
[23:06:34] <just_pink> use imgur.com
[23:06:49] <XXCoder> just_pink: she has sucky onternet connection
[23:10:09] <furrywolf> should finish soon...
[23:12:58] <just_pink> XXCoder: who is she?
[23:13:08] <XXCoder> furrywolf
[23:13:45] <furrywolf> yay! 4MB uploaded!
[23:13:48] <furrywolf> http://fw.bushytails.net/er20collets01.jpg http://fw.bushytails.net/er20collets02.jpg
[23:13:59] <just_pink> cool! so I'm not the only woman here.
[23:14:27] <just_pink> LOL
[23:14:28] <XXCoder> fur those is pretty nice collets.
[23:14:41] <os1r1s> furrywolf: Thats awesome Chenglish
[23:15:39] <furrywolf> it's just... why are they different fonts? did different people design each label? lol
[23:15:44] <XXCoder> sticker styles is all over map lol
[23:16:36] <furrywolf> oh, and the ones that look like two stickers on top of each other? that's one sticker. printed like that.
[23:16:48] <XXCoder> yeah figured that. wonder why though
[23:17:28] <furrywolf> I have absolutely no idea. at all.
[23:18:23] <just_pink> any way in few day the labels will be full of cutting oil
[23:19:29] <furrywolf> no, in a few days they'll be untouched, because a) the chuck hasn't gotten here, b) the mill doesn't work, and c) my back is too tweaked to move the mill out (it's on a cart), much less work on it.
[23:20:30] <XXCoder> I think mine uses e11
[23:20:34] <XXCoder> dunno lol
[23:21:24] <furrywolf> I decided to get ER20 and use MT3 collets for 5/8 and larger.
[23:22:55] <furrywolf> getting a huge collet chuck for small sizes just results in poor accuracy and hitting it on holddowns...
[23:24:44] <XXCoder> yeah. unless you get a smaller collet holder for your er20 collet
[23:24:56] <XXCoder> forgot exactloy what its named. adoptor?
[23:25:08] <XXCoder> it sure eats Z space though if thats a concern
[23:26:01] <furrywolf> I have a MT3 spindle... I got a MT3 ER20 collet chuck. I figure for 5/8 and larger I'll get MT3 collets and put them in the spindle directly.
[23:26:16] <XXCoder> cool
[23:26:29] <XXCoder> dont think I will use larger than 1/4 myself lol
[23:27:08] <furrywolf> that spindle of yours might spin a 1/4 bit in wood... :P
[23:27:48] <XXCoder> lol probably
[23:27:52] <furrywolf> I have a 3/4hp capacitor run motor and a two-stage belt reduction... obviously small as machines go, but a whole lot more torque than a direct-drive toy router motor.
[23:28:46] <furrywolf> I suspect I run into rigidity issues before torque issues.
[23:29:30] <furrywolf> http://fw.bushytails.net/shoptask02.jpg it's not a large machine, but you can see the motors are just a weee bit larger than a toy router. :)
[23:29:43] <XXCoder> nahhh thats tiny
[23:29:44] <XXCoder> jk
[23:29:48] <furrywolf> actually, my sherline probably has a fair bit more torque than that chinese spindle... lol
[23:29:59] <XXCoder> funny thing my uncle has something similiar
[23:30:05] <XXCoder> lathe/mill combo
[23:30:13] <XXCoder> he wants to cnc it up but still unsure
[23:30:16] <os1r1s> furrywolf: Sherline mill or lathe?
[23:30:37] <furrywolf> os1r1s: I have both. The smallest mill, CNC, and an old lathe, manual.
[23:31:05] <os1r1s> Cool
[23:31:32] <os1r1s> furrywolf: I have a sherline 17" lathe cnced and a taig mill with a sherline motor
[23:31:47] <furrywolf> http://fw.bushytails.net/mill02.jpg mill looks like that, no photos of the lathe.
[23:33:33] <furrywolf> http://fw.bushytails.net/lathe01.jpg actually, I do have one of the lathe. lol
[23:33:38] <os1r1s> furrywolf: Mine ... http://gallery.mounicou.com/photos/i-7R8hp6H/0/L/i-7R8hp6H-L.jpg
[23:33:49] <os1r1s> Before converting to linuxcnc
[23:34:44] <XXCoder> lemme get a pic hold on
[23:34:46] <furrywolf> my sherline mill is still set up for Flashcut... which is utter fucking shit. going to linuxcnc it one of these days. the Shoptask is linuxcnc.
[23:36:40] <os1r1s> furrywolf: I haven't seen flashcut. But they are proud of their shit
[23:36:45] <os1r1s> (Expensive)
[23:37:13] <furrywolf> their shit is shit, as is the company.
[23:37:22] <XXCoder> os1r1s: no prices on their site eh
[23:37:48] <os1r1s> furrywolf: I emailed them about their endstop kit. I thought imsrv was expensive at 75. They wanted $170.
[23:38:00] <furrywolf> they tie software versions to rom chip versions, so you can't upgrade software, even bug fixes, without sending the control box to them to have the eeprom chip reprogrammed, for $300.
[23:38:26] <furrywolf> they won't send you a programmed chip, or the file so you can burn it yourself.
[23:38:39] <XXCoder> fur wow thats fucking crazy
[23:38:50] <os1r1s> furrywolf: Wow, that is really fucked
[23:40:07] <furrywolf> I'm stuck with an old, buggy version of their software, that crashes constantly. for example, it crashes if ANYTHING tries covering the window. screensaver, update notification, wifi notifications, etc.
[23:40:25] <furrywolf> so you have to run it on a winxp box with no updates and no antivirus...
[23:40:47] <furrywolf> my solution is to linuxcnc it, but I've been putting my efforts into the shoptask currently.
[23:41:14] <zeeshan> man im so frustrated
[23:41:28] <zeeshan> get that shop task workin!
[23:41:40] <os1r1s> furrywolf: What is shoptask?
[23:42:33] <furrywolf> http://fw.bushytails.net/shoptask02.jpg (old photo, it's now cleaned up and CNC)
[23:42:57] <zeeshan> chunky machine
[23:42:59] <zeeshan> looks heavy
[23:43:08] <furrywolf> It's the largest of the chinese lathe/mill combo machines
[23:43:15] <furrywolf> zeeshan-lab: about 650lbs stripped
[23:43:30] <zeeshan> looks like a good platform to cut gears
[23:43:46] <furrywolf> no, there is no useful way to use both spindles together. heh.
[23:43:51] <zeeshan> ?
[23:43:58] <zeeshan> you lock the lathe chuck
[23:44:01] <zeeshan> and use it only to index
[23:44:08] <furrywolf> you can't move the spindles relative to each other
[23:44:12] <zeeshan> i know
[23:44:21] <zeeshan> thats why the gear needs to be @ axis of mill spindle
[23:44:24] <zeeshan> you'd need a custom mandrel
[23:44:28] <zeeshan> but thats pretty easy to do
[23:45:07] <furrywolf> it's not like a mill-turn machine where the spindles move around independently... the spindles are fixed, and the table moves.
[23:45:47] <zeeshan> =/
[23:45:50] <zeeshan> !!
[23:45:51] <zeeshan> useless!!
[23:46:10] <XXCoder> weird
[23:46:57] <furrywolf> as soon as you find me a good 6" rotary table, then I can do fancy things like that. :P
[23:48:29] <zeeshan> http://i.imgur.com/Zpkp2rb.png
[23:48:33] <zeeshan> WHAT THE FUCK IS GOING ON HERE
[23:48:38] <zeeshan> ive been working on this shit too long
[23:48:52] <XXCoder> zeeshan: there is such thing as being too close to problem
[23:48:56] <XXCoder> take a break
[23:48:59] <zeeshan> dude its so frustrating
[23:49:03] <XXCoder> walk around outside for few minutes
[23:49:17] <zeeshan> im getting double the strain in biaxial tensile test
[23:49:18] <zeeshan> vs uniaxial
[23:49:20] <zeeshan> which is correct
[23:49:24] <zeeshan> but the stresses are all over the place
[23:50:18] <zeeshan> stress(t) = currentPressure(t)*currentRadius(t) / (2*currentThickness(t))
[23:50:21] * furrywolf wonders why the graph extends below zero
[23:50:32] <zeeshan> furrywolf: me being lazy
[23:50:40] <zeeshan> initial points always do that
[23:50:49] <zeeshan> first like 1-2 seconds is completely unreliable
[23:50:52] <zeeshan> because the radius is infinite
[23:51:04] <furrywolf> lol
[23:51:24] <zeeshan> thats one problem w/ direct image correlation method
[23:51:25] <zeeshan> not a big deal
[23:51:55] <furrywolf> so what's the question about the graph? it looks good to me...
[23:52:01] <zeeshan> its not good man
[23:52:04] <zeeshan> you see the green one?
[23:52:10] <zeeshan> it should follow the other curves
[23:52:10] <XXCoder> yeah green looks strange
[23:52:12] <zeeshan> exactly like them
[23:52:19] <XXCoder> it dips hard at end
[23:52:21] <zeeshan> and fail half way in the strain
[23:52:23] <zeeshan> the dip is normal
[23:52:27] <zeeshan> thats when the sample failed
[23:52:30] <XXCoder> ahh
[23:52:32] <furrywolf> I already told you your material has very different properties in each direction... :P
[23:52:37] <zeeshan> furrywolf: this is not smp
[23:52:57] <zeeshan> this is 9000j which is a PP + PE copolymer
[23:53:03] <zeeshan> basically a normal polymer.
[23:53:09] <zeeshan> im using it to validate test
[23:53:17] <furrywolf> also, how are you getting any type of uniaxial test out of your round clamp thingy?
[23:53:19] <zeeshan> if i got this graph correct, i can start thermocycling
[23:53:24] <zeeshan> im not
[23:53:29] <zeeshan> im using a uniaxial tensile tester for that
[23:53:57] <furrywolf> ... so you're plotting two entirely different things on one graph? :)
[23:54:25] <zeeshan> it doesn't matter
[23:54:29] <zeeshan> uniaxial tensile test case
[23:54:35] <zeeshan> equivalent stress is equal to sigma 1
[23:54:43] <zeeshan> strain is equal to epislon 1
[23:54:53] <zeeshan> biaxial tensile test case, equivalent stress is also equal to sigma 1
[23:55:05] <zeeshan> and strain is equal to 2*epislon 1
[23:55:10] <zeeshan> in other words, the stress shouldn't change
[23:55:16] <zeeshan> but the strain will be double in biaxial
[23:55:22] <zeeshan> (which is what the test is also proving)
[23:56:17] <furrywolf> I don't have the experience in that field to have any idea if that is correct or not. heh.
[23:56:32] <zeeshan> this is the problem
[23:56:35] <zeeshan> im in a specialized field
[23:56:42] <zeeshan> theres about 1000 people in it in the world
[23:56:54] <zeeshan> getting help is a big problem
[23:56:56] <furrywolf> I'm sure I could learn it, but I'd want a degree if I did. :P
[23:57:22] <zeeshan> https://cdn.comsol.com/wordpress/2015/02/Measured-stress-strain-curves.png
[23:57:26] <zeeshan> here is what it should look like
[23:57:32] <zeeshan> theres some error in that plot
[23:57:41] <zeeshan> but notice the curve is about the same
[23:57:55] <zeeshan> but fails at "half the stretch"
[23:57:55] <XXCoder> http://picpaste.com/CNCRouter-GN2Zoq3m.jpg
[23:57:58] <furrywolf> so halved in both directions?
[23:57:59] <XXCoder> my incomplete machine
[23:58:06] <zeeshan> yes
[23:58:41] <furrywolf> yours does look like that. lol
[23:59:48] <zeeshan> :(
[23:59:53] <furrywolf> any chance you're missing a scaling factor in the computations on your test rig, like a 4/3 for spherical area or something silly?
