[01:57:34] <Deejay> moinsen
[03:28:41] <FreezingCold> Is there any replacement for pycam?
[03:28:54] <FreezingCold> it hasn't been updated in three years
[03:30:25] <archivist> not a lot happening in the cam world
[03:32:47] <bricofoy> hi
[03:32:59] <bricofoy> someone here ?
[03:33:03] <archivist> no
[03:33:06] <FreezingCold> archivist: How do people machine their parts nowadays? Just manual gcode still?
[03:33:45] <bricofoy> I got a problem trying to use simulation mode on my notebook
[03:34:01] <archivist> some use commercial cam, some manual code and one or three use heekscad
[03:34:23] <archivist> I manual code
[03:34:31] <FreezingCold> archivist: there's decent commercial solutions?
[03:34:43] <bricofoy> linuxcnc complains realtime kernel is not loaded. Why does it need ealtime extensions in sim mode ?
[03:35:01] <archivist> plenty, but often the will destroy your bank balance
[03:35:34] <archivist> bricofoy, because you are not running the sim version by the look of it
[03:36:12] <kengu> commercial cam, vectric something + cambam (freeish) + for laser work inkscape with gcodetools plugin
[03:36:13] <archivist> FreezingCold, which cam you want depends on what you are making
[03:36:40] <bricofoy> I installed linuxcnc-sim packages from buildbot, then chose "axis sim" as a config when starting
[03:37:21] <bricofoy> sim -> axis -> axis_mm
[03:37:52] <archivist> personally I never run the sim version
[03:38:29] <bricofoy> yep, nor do I but I'm not at the shop now, and I wanted to test some ngc files i'm doing now...
[03:39:27] <bricofoy> so as I can't load the file to the real router, I wanted to see if they look well or if there are some big mistakes
[03:42:08] <bricofoy> why does it try to load some RT stuff in simuation ? should I manually change something in ini or hal files ?
[03:43:11] <archivist> dunno seen others have trouble but not remembered the solution
[03:43:22] <archivist> you can also use http://openscam.com/
[03:59:09] <bricofoy> archivist: thanks, I installed openscam
[03:59:24] <bricofoy> I'm triing to figure out how to use it
[04:45:12] <bricofoy> archivist: do you have good results with openscam ? I can't get it to produce something even with files I know ok because I already use them on real wood, or even with the provided example files
[04:45:39] <archivist> not used it yet
[04:46:31] <archivist> and it wont install on this box probably because the OS is old
[04:46:45] <bricofoy> ok thanks
[04:55:51] <bricofoy> well I tried with 2.6 branch and the sim works ok :)
[04:56:18] <bricofoy> i first tried with 2.5 because it's the same I have on the real machine
[04:56:32] <bricofoy> so problem solved
[06:33:20] <zq_> why does ./configure insist on libglib-2.0 being present even with --without-libmodbus?
[06:34:05] <zq_> why does modbus.c even depend on glib, christ
[06:49:44] <archivist> why are you confusing glib with modbus :)
[06:50:02] <zq_> archivist: why do you think i have?
[06:51:04] <archivist> because you mention modbus on both lines
[06:51:31] <zq_> and?
[06:51:38] <zq_> hal/comp/modbus.c
[06:51:45] <zq_> or something like that. invoke a find
[06:52:46] <zq_> oops, i wasn't in master
[06:53:26] <zq_> still, the glib dependency is very non-essential
[06:54:59] <archivist> why do you think that
[06:55:29] <zq_> why don't you think that?
[06:56:01] <zq_> as of master, the only dependencies are gscreen and gmoccapy, whatever that is
[06:56:33] <zq_> is there a -dev version of this?
[07:31:02] <CaptHindsight> http://www.pbclinear.com/Videos/All/Factors-That-Affect-Repeatability every time some wobbly design comes up for a router or similar they should refer to these videos
[07:31:29] <CaptHindsight> http://www.pbclinear.com/Train/VideosLLC/Linear-Motion-Design/Eleven-Common-Mistakes-In-Linear-Motion
[07:32:09] <CaptHindsight> http://www.pbclinear.com/Videos/All/Bearing-Selection-Criteria
[09:05:39] <eneuro_> Hello again, just found this thread http://linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/16561-emc2-in-a-virtual-machine-for-simulation while I'm interested in simulating G-code in Axis with HAL and is it possible to go inside LinuxCNC and maybe log LPT I/O in simulation mode with something like virtual LPT?
[09:06:03] <zq_> eneuro_: halscope
[09:09:01] <eneuro_> OK. I will see, but is it possible to write something like hardware simulator of circuit connected to LPT port-I mean LinuxCNC sends something to LPT I/O then my compiled program on Linux BOX catch it and responds in programmed way like my real future PCB mikrocontroler could behave when see such outputs on LPT?
[09:10:12] <eneuro_> This way I could log LPT I/O state my self by It could be nice to simulate response from connected hadware...
[09:13:23] <archivist> probably quicker to attach hardware
[09:14:55] <archivist> you can also create a 3d model of your machine using vismach
[09:15:14] <archivist> which will move according to your gcode
[09:18:02] <eneuro_> archivist: But sometimes I'd like to run LinuxCNC in VirtualBox... vismach looks nice... I've found HAL tutorial http://linuxcnc.org/docs/html/hal/tutorial.html . I will try to generate G-Code myself from my CAE and simulate in LinuxCNC with HAL ;)
[10:21:35] <CaptHindsight> has anyone see a small motorized or pneumatic nibbler for cutting light wire, thread, fiber etc?
[10:22:41] <CaptHindsight> small enough to mount on robot arms or gantries
[10:24:15] <archivist> I have a small nibbler but it would never handle stuff that thin and flexible
[10:24:25] <Einar1> What do you mean by small? Something like these: http://www.feinus.com/en_us/sheet-metal-work/nibblers/
[10:25:04] <archivist> and dont confuse nibblers with shears :)
[10:25:09] <zeeshan> those are some sexy looking nibblers
[10:25:21] <zeeshan> europeans know how to make good looking tools :p
[10:25:48] <zeeshan> http://www.feinus.com/en_us/sheet-metal-work/nibblers/blk-35-017008/
[10:25:49] <zeeshan> holy shit
[10:25:51] <CaptHindsight> preferably <1kg, ~30ga copper wire might be the toughest application
[10:25:55] <zeeshan> look at the thickness of steel the person is cutting
[10:26:26] <Einar1> No. The Fein nibbler I have cannot be confused with shears. It makes thousands of small sharp cutoffs. That's why I rather use shears.
[10:26:27] <CaptHindsight> I can make one but ....
[10:27:18] <archivist> CaptHindsight, I think you need cutters or shears rather than a nibbler
[10:27:21] <Einar1> Cutting wire with a nibbler??
[10:27:22] <CaptHindsight> it also has to be sharp enough to cut few mil dia thread, fibers
[10:27:44] <CaptHindsight> the actual cutter is similar
[10:27:47] <archivist> nibblers are brutes not sharp
[10:28:30] <CaptHindsight> mini shears
[10:28:40] <Einar1> Sounds like you are looking for shears. http://www.boschtools.com/Products/Tools/Pages/BoschProductDetail.aspx?pid=1500C
[10:29:19] <CaptHindsight> those are all way to big, lets say a robot arm has to cut a single thread
[10:29:20] <Einar1> Do NOT buy chinese clones. They will not cut thin stuff!
[10:29:48] <CaptHindsight> this is getting caught up in semantics
[10:29:53] <archivist> CaptHindsight, there were some mini shears for sewing use
[10:30:05] <archivist> batery driven
[10:30:21] <CaptHindsight> close enough, just add power vs batteries
[10:30:42] <zeeshan> other than home depot and local hardware stores
[10:30:46] <zeeshan> where can i buy 8/3 SOOW cable
[10:30:51] <CaptHindsight> it's probably closer to an electric hair trimmer
[10:30:52] <zeeshan> and 8/4 AC90 (Armor) cable
[10:31:39] <archivist> CaptHindsight, fleabay 191096652617
[10:31:53] <CaptHindsight> zeeshan: that was used for old service entrance cable
[10:31:56] <Einar1> This one: http://news.thomasnet.com/fullstory/Pneumatic-Wire-Cutter-features-interchangeable-cutter-heads-29811
[10:32:05] <zeeshan> which one
[10:32:23] <CaptHindsight> I saw the Model 590 Micro-Pneumatic
[10:33:06] <CaptHindsight> multiconductor 8-2ga with steel wrap
[10:34:56] <CaptHindsight> I was looking for an electric version of version of that http://xuron.com/index.php/main/industrial_products/11/59
[10:35:23] <CaptHindsight> looks like I'll have to mod or just make it
[10:35:55] <Connor> CaptHindsight: How much you plan on cutting?
[10:36:57] <CaptHindsight> Connor: the cutting blade should be changeable, millions of cuts, wire, thread, kevlar, carbon fiber etc etc
[10:38:22] <Connor> I use these.. http://www.traintekllc.com/prodinfo.asp?number=XUR-90028&variation=&gclid=CPT_5N7mur4CFTQQ7AodnmIAaQ
[10:38:27] <Connor> but.. they're manual.. :)
[10:38:31] <Connor> Really nice cutters..
[10:39:17] <Connor> Used them in model trains... and electronics..
[10:39:44] <CaptHindsight> think of a robot arm filament dispenser that works like a fishing rod/reel that needs to cut the filament
[10:42:03] <Connor> CaptHindsight: What are you making ?
[10:42:30] <CaptHindsight> I just described it ^^
[10:42:38] <Connor> Oh. okay.
[10:42:43] <Connor> sorry.. a bit slow today
[10:42:51] <Connor> What's it for ? :)
[10:42:58] <CaptHindsight> so the end of the rod needs a cutter
[10:42:59] <Einar1> I have seen such cutter heads on a huge machine that make cable harnesses for cars. It pulls out wires to right length, cut and strip and crimp a connector to it. The tools are "snap-in" tools.
[10:43:44] <Einar1> I don't know if these tools are specially made for them or COTS parts.
[10:45:50] <CaptHindsight> something like an industrial hair trimmer that vibrated a blade though a comb
[10:46:18] <CaptHindsight> http://www.photo-dictionary.com/photofiles/list/1235/1724hair_trimmer.jpg
[10:47:16] <CaptHindsight> Connor: robot fiber dispenser and applicator
[10:47:58] <Einar1> Get the cutter head for one of these: http://cfnewsads.thomasnet.com/images/large/014/14622.jpg
[10:48:51] <Einar1> Then another cutter blade (Carbide) that is stationary. Each time a blade of the cutter head passes the stationary blade it will cut.
[10:49:47] <CaptHindsight> yeah, I was hoping to find something off the shelf, but it looks like another project for now
[10:50:25] <Einar1> This one? http://www.alibaba.com/product-detail/ETG017LD-cordless-branch-cutter-garden-branch_495186280.html
[10:54:02] <CaptHindsight> hmm maybe a porcupine trimmer vs hair trimmer
[10:54:30] <CaptHindsight> maybe there some shear for fur thats really tough
[11:00:10] <CaptHindsight> https://www.sullivansupply.com/cart/ia/p-665-oster-510-shearmaster-clipper-with-blades.aspx
[11:16:37] <CaptHindsight> http://www.jaeberly.com/id9new.html
[11:22:10] <CaptHindsight> http://www.sasgripper.com/products/nipit/nipit_sn.htm
[11:24:18] <CaptHindsight> http://www.sasgripper.com/products/nipit/nipit_MSFMSFP.htm
[11:58:28] <demimsy_> So this kind of seems like a safety concern: when turning machine power on then off, it starts to send a floating signal to the motors. its not a large signal so the motors move fairly slowly, but they still move. Is this a known issue?
[11:59:05] <cradek> your hardware is misconfigured if you have uncontrolled movement
[11:59:30] <cradek> if the loop is not closed, your amps should be disabled
[11:59:42] <cradek> this is what the amp-enable-out hal pins are for
[12:03:52] <demimsy_> it only seems to be for one axis though
[12:07:10] <demimsy_> amp-enable-out is false for both motors
[12:08:45] <CaptHindsight> check with a meter
[12:09:15] <CaptHindsight> maybe the amps are ignoring the enable when it's off
[12:09:50] <CaptHindsight> did the problem just start?
[12:09:52] <demimsy_> interesting, command to the motor from linuxcnc is 0
[12:10:15] <demimsy_> must be in the motor's driver
[12:10:49] <Jymmm> cradek: I had a question, you busy?
[12:10:50] <demimsy_> the problem has been around since the start, but as I am nearing completeion of the project, I am trying to work out the finer kins
[12:10:56] <CaptHindsight> check the enable line at the driver with a meter
[12:11:16] <CaptHindsight> oh, then you might want to check your wiring as well
[12:11:39] <demimsy_> yeah, that and the parameter settings of the motor driver
[12:11:44] <CaptHindsight> verify the enable signal from the IO board, check the enable signal at the drive
[12:11:50] <demimsy_> see you when i get out fo the rabit hole
[12:12:00] <CaptHindsight> you'll figure it out
[12:14:57] <IchGuckLive> hai all B)
[12:16:06] <cradek> it's normal for a fixed zero velocity command to cause a little creep in a velocity mode servo amp -- if there is not pid holding it in position it must be disabled, not just commanded zero velocity
[12:16:22] <cradek> Jymmm: dataja
[12:16:41] <Jymmm> cradek: say what? lol
[12:17:58] <IchGuckLive> XXCoder1: has been a quiet night here
[12:18:32] <Jymmm> cradek: I'm having an issue with my laser. When I vector outline a 1/2" square it ends up looking like this: [ ] ....
[12:19:04] <cradek> what do you mean vector outline?
[12:19:11] <Jymmm> cradek: It seems that when motion is ONLY in the X-axis (not Y or X&Y) that this happens....
[12:19:20] <IchGuckLive> Jymmm: does your stansdard load G-code has G64
[12:20:44] <Jymmm> cradek: It's as iif whatever singal tells the laser to fire, it's getting thru. The motion system itself is fine, but what do you call it when the tool (laser, plasma, edm, etc) has to "fire" in unison with the motion? Trajectory?
[12:21:11] <IchGuckLive> M8 M9
[12:21:17] <IchGuckLive> is my laser command
[12:21:19] <Jymmm> IchGuckLive: There is no g-code.
[12:22:07] <Jymmm> cradek: vector outline, just outline a square as oppose to raster engrave it.
[12:22:28] <Jymmm> (raster = solid fill)
[12:22:38] <IchGuckLive> Jymmm: so on what command does the mashine move
[12:22:45] <Jymmm> IchGuckLive: There is no g-code.
[12:23:37] <IchGuckLive> is the mashine just moving back and forth and getting impuls on retrace
[12:24:39] <IchGuckLive> what is the source to the mashine png svg pdf dxf eps
[12:25:00] <Jymmm> cradek: ?
[12:25:16] <IchGuckLive> what do you mean vector outline?
[12:25:20] <Jymmm> cradek: I'm loking for the phrasing or temrinology here
[12:26:21] <cradek> Jymmm: I think I understand what you're asking about, but I don't know a specific word for that, other than the generic words like unison/synchronized/etc
[12:26:24] <Jymmm> cradek: I suspect what ever tells the laser to fire inconjunction with motion is on an logical OR
[12:26:45] <cradek> I assume you're trying to figure out how to best ask their support for help?
[12:27:24] <cradek> in that case I'd suggest explaining only what you DO and SEE, and try not to describe it in any technical way or using any special lingo
[12:27:34] <cradek> bbl, lunchtime
[12:28:00] <IchGuckLive> Jymmm: galvos involved
[12:28:11] <Jymmm> cradek: Well, they are semi-useless, but yes. They default to "you probably have a failing tube", but this action occures prdominantly when there is X-Motion-Only. IF there is Y or Y&X not so much.
[12:29:49] <Jymmm> cradek: It's almost as if there is a bad cap on whatever X-axis tells the laser to fire so the signal isn't getting thru properly.
[12:30:26] <cradek> if it has some circuitry that automatically senses motion and makes it come on, I agree it sounds like the fault might be there
[12:31:28] <Jymmm> cradek: Yeah, I'm just trying to find the right wording so they can inquire with engineering on the specifics.
[12:31:50] <IchGuckLive> blanking
[12:31:51] <cradek> again, say in simple words what you do and see
[12:32:33] <IchGuckLive> like lasershowes do
[12:32:37] <cradek> maybe take pictures of a problematic square and a 45 degree rotated square that works right (if it does)?
[12:32:41] <cradek> bbl
[12:33:11] <Jymmm> cradek: I tried that already, they are defaulting to "if a replacemant tube doens't fix it, you can return it less shipping charges ($150 both ways). Ok, when you get back =)
[12:33:16] <IchGuckLive> symtomes like your come if there is not enoph stop and line points
[12:34:12] <IchGuckLive> my 32k galvo system needs 5 line points bevor 45deg + edge
[12:44:18] <IchGuckLive> Jymmm: you are not talking with my ? ;-)
[12:46:10] <Jymmm> IchGuckLive: You are jumping all over the place. I'm trying to focus on one item/thing at a time right now. I need to isolate the cause of the issues with the way the laser is firing in only non-x-axis-only motion.
[12:46:28] <IchGuckLive> on raster mashines motion in X is ofeen prohibit cause line with is not inside raster
[12:47:07] <Jymmm> IchGuckLive: Again, NOT THE ISSUE right now. this has nothign to do with artwork
[12:47:38] <Connor> https://www.youtube.com/watch?v=NAxMyTwmu_M
[12:49:40] <IchGuckLive> Jymmm: ok yust wantet to help on my laser systems failue nowhow
[12:57:55] <IchGuckLive> hi Cylly what a hot sumer day
[12:59:18] <Jymmm> IchGuckLive: I don't understand. Was that a question or statement?
[12:59:29] <Jymmm> Connor: Interesting.
[12:59:47] <Connor> Jymmm: Hits the nail on the head.. Freaking FCC
[13:00:25] <Jymmm> Connor: It's not the FCC itself, it tried, but the carrier's lawyers found loopholes.
[13:01:00] <Jymmm> Connor: Go signup on the waiting list for google fiber.
[13:01:38] <IchGuckLive> Jymmm: statemernt ;-)
[13:02:08] <Jymmm> Connor: You get 5/1Mbps for free, and 100Mbps for something like $40-$$8/mo depending on location.
[13:02:26] <Jymmm> Wait, sorry, gigabit
[13:02:51] <Jymmm> ...for $40-$80/month.
[13:03:05] <IchGuckLive> Max is the wizzard word
[13:03:18] <IchGuckLive> so if 100 in seet divisor is on
[13:03:29] <IchGuckLive> street ;-)
[13:06:33] <IchGuckLive> on UsaAFB shift time i got 42000 download friday at USafb shift end all calling home i reatch 100kbs
[13:08:39] <IchGuckLive> Loetmichel: hast du LTE
[13:08:40] <MrHindsight> Jymmm: that's an interesting problem
[13:08:48] <Loetmichel> IchGuckLive: nein
[13:08:51] <Jymmm> MrHindsight: which?
[13:09:13] <MrHindsight> Jymmm: the laser doesn't fire in only 1 axis
[13:09:20] <Loetmichel> IchGuckLive: plain old DTAG 16Mbit adsl+
[13:09:36] <MrHindsight> the square ends up as a [ ]
[13:09:39] <IchGuckLive> Thanks
[13:09:54] <Jymmm> MrHindsight: If LASER_FIRE is an Logical OR with X-Fire and Y-Fire, then it makes sense
[13:10:28] <Jymmm> MrHindsight: In a Y-Only or X&Y motion, there will always be a FIRE signal
[13:10:47] <Jymmm> But in X-Only, it gets semi-puzzling.
[13:11:15] <Jymmm> MrHindsight: But, in a test I did last night I got soem interesting rresults.
[13:11:24] <archivist> might be a fault in the kerf adjuster
[13:11:27] <Loetmichel> had a nice epiphany at the company today: made a tracert to microsoft com. first 3 hops 1500ms each... tried the same tracert on my home machine (via VNC) -> 66ms for the first three hops ;-)
[13:11:37] <MrHindsight> Jymmm: if i had your galvo controller in front of me i could see why, but it might be like you mention, it's just weird to me that they would do it that way
[13:11:52] <Jymmm> MrHindsight: Not galvo
[13:11:53] <Loetmichel> ... now i no longer wonder why the internet at the company is so slow ;-)
[13:12:25] <MrHindsight> Jymmm: Cartesian movements?
[13:13:03] <MrHindsight> then this sounds easier to debug and I see why you are saying that about the OR
[13:13:21] <micges> Loetmichel: active torrents
[13:13:43] <Jymmm> MrHindsight: The motion system is perfectly fine, already checked that.
[13:13:53] <MrHindsight> yeah sounds like it
[13:14:02] <Loetmichel> micges: not possible
[13:14:07] <Loetmichel> i am the admin
[13:14:09] <Jymmm> MrHindsight: If I do a 4" long vertical line...
[13:14:30] <Loetmichel> pouter said: no mentoinable traffic on the line at that time
[13:14:54] <Loetmichel> and the second and third hop are at the isp.
[13:15:13] <Loetmichel> so a torrent couldnt interfere there
[13:15:20] <Loetmichel> s/couldnt/shouldnt
[13:16:27] <IchGuckLive> lo OS related
[13:17:34] <Jymmm> MrHindsight: The motion "ramps up/down" during the first/last 0.01". Now, as it does this, it *ALSO* alters the laser power to compensate for the motion speed. If during this ramp up/down the signal going to the laser fire/power levels beigns strong, then tapers off, and reverses at the end of the move as well.
[13:18:08] <MrHindsight> Jymmm: yes, I follow you and see why that happens
[13:18:12] <Jymmm> Square looks like [ ]
[13:18:28] <Jymmm> vector outlined square that is
[13:18:46] <Jymmm> which is just a pen plot of a square
[13:19:29] <archivist> Jymmm, that varies the power to get the kerf/marking constant, there is probably an analog circuit to sense speed and a summing circuit
[13:19:35] <MrHindsight> Jymmm: does the laser fire at all during the only horizontal moves?
[13:19:56] <Loetmichel> ah, btw: finally found time to wire the plt port pin 17 to the VDF. and reprogram the vfd to more reasonable ramp times.
[13:19:58] <IchGuckLive> Jymmm: why is laser power ramped you are not moving at near light speed
[13:20:16] <MrHindsight> IchGuckLive: not his design
[13:20:18] <Loetmichel> MUCH more convenient... and 2 sec ram instead of 40 sec ram is MUCH better! ;-)=
[13:20:27] <Jymmm> archivist: That's what I'm thinkging, but I'm not sure of the phrasing so I can convery that to tech support so they'll ask engineering
[13:20:31] <MrHindsight> somebody in China's design or copy of
[13:20:58] <Jymmm> MrHindsight: Yes, but only at the beginning/end of the move,
[13:21:08] <archivist> Jymmm, micges did a fiddle for linuxcnc to do the same, there is a wiki page
[13:21:24] <MrHindsight> Jymmm: can you get to the control board? or boards
[13:21:54] <Jymmm> MrHindsight: Yes, I pulled the controller yesterday, no visible cold solder jints or domed caps.
[13:22:22] <Jymmm> MrHindsight: Pulled the laser last night, same visiaully.
[13:22:33] <Jymmm> alsot all SMT
[13:22:37] <MrHindsight> Jymmm: can you tell if this is done digitally in a uMicro/DSP or in analog?
[13:22:55] <MrHindsight> pics of the board might help us
[13:22:59] <Jymmm> The controller board is two xilinx 5402's
[13:23:22] <archivist> any A-D
[13:23:31] <IchGuckLive> did you change the axes to see if it is in the other also
[13:23:47] <MrHindsight> any analog devices? a few opamps for math
[13:24:07] <MrHindsight> IchGuckLive: yes it's during horizontal only movement
[13:24:13] <Jymmm> The motor driver boards uses 298's =)
[13:25:04] <Jymmm> I believe it's a 40MHz PWM, but I don't know the values/limits.
[13:25:58] <MrHindsight> Jymmm: will they swap boards with you? or will that just take too long + $$
[13:27:04] <Jymmm> MrHindsight: Since they "suggested" if their 4" square test failed, that the tube was failing. repacement tube (which includes the RF boards too) is $1200 shipped
[13:27:40] <MrHindsight> odd assumption since it only happens in horiz only
[13:27:41] <Jymmm> It's literally a drop in toolless operation
[13:28:51] <micges> Jymmm: hi, what problem do you have?
[13:28:51] <MrHindsight> but i see bassackward designs all the time
[13:28:59] <Jymmm> Well, preminantly in the horitz, I'm writting a big email now to TRY and (prybar out of them) some voltage/signal test points/values
[13:29:16] <Jymmm> micges: You'll have to scroll back, too much info to repeat.
[13:29:52] <MrHindsight> Jymmm: if it's happening in more than just only horiz moves then thats different
[13:30:37] <Jymmm> MrHindsight: That's the thing, the print driver doesn't allow to change the raster axis which would confirm/deny this.
[13:30:40] <IchGuckLive> im off BYE
[13:31:09] <Jymmm> MrHindsight: I emulated the horitz rastering and got interesting results.
[13:31:42] <MrHindsight> I'd say in summation that his laser does not fire (except for the first few thousandths) when in a horizontal only move in either direction
[13:31:50] <Jymmm> If speed is at it's lowest 0.02%, than I get strong deep marks at 100% power,.
[13:32:08] <Jymmm> If I change the pwr to 10% it's still strong, just not as deep....
[13:32:11] <Jymmm> BUT...
[13:32:43] <Jymmm> If I change the speed form 100% to 80% 60%... 40% 30% etc...
[13:32:54] <MrHindsight> sounds like you can write this up :)
[13:33:29] <Jymmm> I get no go, untill I am below 4% speed.
[13:33:56] <Jymmm> Which makes sense in my theroy of the laser_fire signal...
[13:34:04] <MrHindsight> I can easily follow that, now for a non-native English speaker??
[13:34:18] <micges> noooo
[13:34:38] <Jymmm> If it's PWM, at lower speed it's HIGH much of the time. 00111100111100111100
[13:35:01] <Jymmm> then the FIRE signal might be gettign thru 80% if the time.
[13:35:25] <Jymmm> If I increase the speed, the PWM might be: 0011001100110011
[13:35:48] <Jymmm> if only 80% of that signal is gettign thru, I might get what I'm seeing now.
[13:36:11] <MrHindsight> Jymmm: but at any including high speeds XY and vertical movements the laser works fine?
[13:36:13] <Jymmm> During the beginning/ending moves, the speed is slow.
[13:37:17] <MrHindsight> i guess we should decide what X and Y is and stick to that for clarity, VERT and Horiz
[13:37:18] <Jymmm> MrHindsight: Sucks in X-Axis-only, works "better" in Y-only -or- X&Y
[13:37:36] <Jymmm> X is left yo right, horitz
[13:38:12] <Jymmm> What I need is a damn scope =)
[13:39:12] <MrHindsight> stick to using the same terms when you write it up, don't jump between using VERT and Y-axis, just use Y and X, that confuses people
[13:39:20] <MrHindsight> yeah, a scope would help
[13:39:45] <MrHindsight> sounds like you have a good description
[13:39:55] <Jymmm> MrHindsight: Oh he's a smart guy, just limited in his role in what he's allowed to offer
[13:39:56] <MrHindsight> can't find a cheap scope?
[13:40:21] <Jymmm> I found a 35MHz (circa 1977) asking $60
[13:40:29] <MrHindsight> yeah frustrating, especially when dealing with overseas
[13:40:39] <Jymmm> MrHindsight: USA baby
[13:40:56] <Jymmm> MrHindsight: Universal Laser Systems, Arizona
[13:41:07] <MrHindsight> road trip? :)
[13:41:35] <Jymmm> MrHindsight: Maybe, but they wuld rather sell me something new to take back instead =)
[13:41:47] <MrHindsight> sure
[13:42:10] <Jymmm> @ $38,000 USD
[13:42:16] <archivist> do they have a proper service manual
[13:42:23] <MrHindsight> tell them how you were discussing their products with >100 in IRC the other day
[13:42:45] <Jymmm> archivist: OH HELL NO, that's "Engineering Only", guarded with their lives.
[13:42:56] <MrHindsight> the type that tend to buy laser cutters
[13:43:24] <archivist> but not from companies with crappy suport
[13:43:34] <Jymmm> MrHindsight: Ha, Iw as discussing on a forum with 20,000 ppl and that they actually are members of.
[13:43:45] <MrHindsight> and your other suppliers are more flexible
[13:44:06] <MrHindsight> that might help send the message
[13:44:14] <Jymmm> MrHindsight: Not in this case.
[13:44:35] <MrHindsight> sounds like Grizzly
[13:45:05] <MrHindsight> try to find a scope
[13:45:43] <Jymmm> MrHindsight: oh no, they have EXCELLENT support. They are just in the business of making money. They even let me borrow a laser power meter at no charge other than shipping costs.
[13:46:22] <Jymmm> This is a vectored SQUARE http://i61.tinypic.com/wbeyro.jpg
[13:46:45] <Jymmm> It's should be consistant all around.
[13:47:25] <archivist> looks pulsed one direction and constant in the other
[13:47:42] <Jymmm> This are X&Y motion... http://i61.tinypic.com/f9p3k5.jpg
[13:47:46] <archivist> very non round
[13:48:02] <Jymmm> that is how it SHOULD look like.
[13:48:11] <Jymmm> the last pic that is, on all sides.
[13:48:54] <archivist> last pic shows variation in power
[13:49:20] <Jymmm> archivist: that might be the material (partical board)
[13:49:31] <Jymmm> angle of camera too
[13:49:51] <Jymmm> oh, I see what you are saying
[13:49:53] <MrHindsight> get a scope and post high res pics of the board, we can try to RE it
[13:50:03] <archivist> nah too consistent with where the light /dark is, not the corners are darker than the sides
[13:50:54] <Jymmm> archivist: Is what *YOU* are seeing consistant? A pattern though?
[13:51:14] <Jymmm> a slope if you will?
[13:51:26] <archivist> yes I see it not compensating for the speed properly
[13:51:50] <Jymmm> Like the signal isn't being sent/received properly?
[13:52:02] <Jymmm> like maybe a bad capacitor?
[13:52:09] <archivist> a fault/adjustment
[13:52:31] <Jymmm> No adustment otions.
[13:52:47] <MrHindsight> a high res scan of the PCB would help so we can see part numbers
[13:53:06] <Jymmm> MrHindsight: Hold on, don't get your panties in a bunch =)
[13:53:27] <MrHindsight> nah, just leaving :)
[13:53:39] <Jymmm> lol, I'm posting pic now
[13:56:14] <Jymmm> controller board http://oi61.tinypic.com/153lhtc.jpg
[13:56:43] <Jymmm> Yes, those ARE 30pin SIMM slots =)
[13:59:26] <CaptHindsight> yeah A/D's
[14:01:20] <CaptHindsight> an 8051 based uMicro
[14:02:26] <CaptHindsight> and a mystery chip between the two FPGA's
[14:02:49] <CaptHindsight> or did the print just not show up in the pic?
[14:03:23] <CaptHindsight> huh 2 uMicros
[14:04:25] <Jymmm> just the lighting
[14:04:30] <CaptHindsight> and two 6k gate fpga's
[14:05:31] <CaptHindsight> I see why you were asking about the SMT caps
[14:05:45] <Jymmm> =)
[14:06:02] <CaptHindsight> the analog section is the upper right hand area
[14:06:02] <Jymmm> I was/am hoping it's a bad cap =)
[14:06:20] <CaptHindsight> around the AD7228
[14:06:59] <Jymmm> The tw connectors in the top left are "db9 serial port" and next to it "db25 parallel port"
[14:07:03] <Jymmm> two*
[14:08:23] <CaptHindsight> yeah some bulging 10 year old caps would be too easy
[14:08:57] <CaptHindsight> date codes are from ~02'
[14:09:24] <Jymmm> and on the motor driver board (below it) only has 4 electrolytic caps, not buldging, and motion is in perfect working order - of course =)
[14:09:35] <Jymmm> one per axis
[14:09:46] <Jymmm> XYZ and R (rotary)
[14:09:58] <Jymmm> but I dont' have a rotary attachement.
[14:11:33] <CaptHindsight> is that an actual PROM or Flash?
[14:11:58] <Jymmm> probably prom
[14:12:43] <CaptHindsight> if we even debug this can you de/solder smt?
[14:13:42] <Jymmm> Not sure on the fpga's, but I can learn for anythng else.
[14:14:07] <CaptHindsight> at least no BGA's
[14:14:20] <CaptHindsight> there is some pretty small stuff there
[14:15:16] <Jymmm> Right now, I think it's isolating WHERE the probelm is... controller? cable? laser?
[14:15:54] <cradek> if it were from 1980 instead of 1990 it would've come with "theory of operation" documentation and schematics...
[14:16:27] <jdh> and source code for the rom
[14:19:53] * SpeedEvil sighs.
[14:20:01] * SpeedEvil stabs modern electronics in the pooper.
[14:21:41] <CaptHindsight> Jymmm: you've probably wiggled every connection 4 times by now
[14:22:19] <Jymmm> CaptHindsight: Not yet, still doing visual inspections. PS comes out today.
[14:22:44] <SpeedEvil> Hit the PSU with a scope first, if you can
[14:23:02] <Jymmm> SpeedEvil: If I had a scope
[14:23:15] <CaptHindsight> whats left of the lithium battery?
[14:23:26] <SpeedEvil> Well - depending on the cost of the repair -a scope may be a reasonable investment
[14:23:30] <Jymmm> CaptHindsight: more specifically?
[14:23:45] <CaptHindsight> it would nice if it ends up being bad power
[14:23:46] <Jymmm> U22?
[14:23:57] <CaptHindsight> the coin
[14:24:06] <Jymmm> you said LEFT of the battery
[14:24:20] <CaptHindsight> meant voltage
[14:24:27] <Jymmm> 3.04V
[14:24:55] <Jymmm> It's just for memorizing the Z focus values anyway.
[14:25:17] <Jymmm> calibration
[14:31:40] <Jymmm> They DID provide me with wire harness diagram, it says things like: LAS. PULSE "INPUT", From: P15-1, to: P14-6, and other such things. So I have an idea WHERE thhings are, just not what should be on them =)
[14:32:32] <Jymmm> "FIRE INDICATOR OUT"
[14:33:30] <Jymmm> LAS. PULSE "INPUT"
[14:46:07] <CaptHindsight> I don't see any boards for sale either, just those nebulous industrial supply site saying they can quote you to fix it with a 1 year warr
[14:46:37] <CaptHindsight> http://www.unisgroup.com/en/Product-catalogue/diversen/2/others/150-0200-rev-e.html
[14:47:09] <CaptHindsight> sure are a lot of these types of sites, they clutter up searches for parts
[14:48:59] <Jymmm> Bah, after a long ass email explainng details the repsonse is: "your tube is failing. Well test for if you pay shipping both ways. blah blah blah"
[14:51:42] <Tom_itx> not the reply you were after?
[14:53:06] <Jymmm> No, I wanted test point voltages/signals that I can compare against.
[14:53:55] <Tom_itx> you could have gotten them from the unit when it was new ya know
[15:00:09] <cradek> you should be looking for differences between X and Y
[15:00:21] <cradek> you have a working model to compare against right in front of you
[15:01:43] <Jymmm> cradek: I think *both* X and Y are weak, just that X ir much more so.
[15:01:55] <Jymmm> s/ir/is/
[15:26:52] <zeeshan-laptop> i
[15:26:53] <zeeshan-laptop> hi
[15:34:26] <zeeshan-laptop> is there a single point attachment for a mill
[15:34:45] <zeeshan-laptop> that i can use to cut out a 5" diameter circle out of ss 304?
[15:35:06] <cradek> a boring head is very much like that
[15:35:10] <zeeshan-laptop> yea
[15:35:21] <zeeshan-laptop> but i dont know if its wise to be cutting 5" diametes with it
[15:35:28] <zeeshan-laptop> hmm
[15:36:02] <MrHindsight> 80c320 dev board is also EOLed
[15:36:03] <zeeshan-laptop> boring head w/ a custom tool bit
[15:36:32] <cradek> "it depends"
[15:37:59] <zeeshan-laptop> http://www.practicalmachinist.com/vb/attachments/f38/93845d1386983896-removing-stuck-arbor-maxwell-q2-boring-head-1-2-ez-set-no-30-img_3072.jpg
[15:38:01] <zeeshan-laptop> this could work
[15:42:45] <SpeedEvil> thick stainless?
[15:42:56] <zeeshan-laptop> no
[15:43:01] <zeeshan-laptop> 35 thou
[15:43:15] <zeeshan-laptop> with a shape memory polymer on one side of it
[15:43:44] <SpeedEvil> That sounds 'fun'.
[15:44:08] <zeeshan-laptop> i wanna use a single point turning tool
[15:44:11] <zeeshan-laptop> thats sharp
[15:44:18] <zeeshan-laptop> so the smp doesnt delaminate
[15:44:30] <MrHindsight> http://www.edsim51.com/ this seems to be the best/last 80c320 simulator
[15:44:40] <zeeshan-laptop> i think if i used a rotary table and end mill, it would rip some of the smp off the sheet
[15:44:55] <SpeedEvil> zeeshan-laptop: I suppose laser isn't an option?
[15:45:00] <zeeshan-laptop> no
[15:45:05] <zeeshan-laptop> it will distort the material
[15:45:09] <zeeshan-laptop> this is for lab grade specimen
[15:45:21] <zeeshan-laptop> for bulge testing, cup drawing, etc
[15:45:25] <MrHindsight> maybe engrave your way down
[15:45:41] <SpeedEvil> I was meaning cut a nice slot to the SS in the polymer
[15:45:43] <zeeshan-laptop> heat affected zone will throw things off
[15:46:06] <zeeshan-laptop> might change the composition of it =/
[15:46:13] <zeeshan-laptop> i was thinking water jet,
[15:46:18] <zeeshan-laptop> but the edge finish will be not good
[15:47:55] <zeeshan-laptop> i could mount the square stock onto a face plate
[15:48:05] <zeeshan-laptop> and use a face grooving tool
[15:48:07] <zeeshan-laptop> might be faster
[15:48:31] <SpeedEvil> how exactly 5" ?
[15:48:44] <zeeshan-laptop> +/- 10 thou is fine
[15:48:47] <zeeshan-laptop> as long as its square
[15:48:50] <SpeedEvil> do you have a bit to play with to try surface finishes?
[15:48:54] <zeeshan-laptop> yes
[15:48:57] <zeeshan-laptop> a lot infact
[15:48:58] <zeeshan-laptop> lol
[15:49:03] <zeeshan-laptop> 2 skid fulls
[15:49:25] <SpeedEvil> I've found the ideal bit. Just chuck this up and plunge.
[15:49:26] <SpeedEvil> http://www.ebay.co.uk/itm/BOSCH-2608602793-ANGLE-GRINDER-DIAMOND-CUTTING-DISC-125MM-5-INCH-/310652568672?pt=UK_Home_Garden_PowerTools_SM&hash=item4854560460
[15:49:40] <zeeshan-laptop> haha
[15:50:31] <SpeedEvil> I wonder what would happen if you did slowly plunge that - with adequate coolant - into a 4.5" hole
[15:51:04] <gene78> 2 problems with current 2.5.4 here, trying to set limits that will save the chuck, hitting run says exceeds z limit, click run any way doesn't
[15:51:42] <gene78> and standing on a manual move, it ignores the limit switch.
[15:51:44] <mozmck> SpeedEvil: nothing would happen. It would go down into the hole and come back out.
[15:52:07] <gene78> can I fix that in the .ini file somehow?
[15:52:27] <SpeedEvil> mozmck: err - it's larger than the hole
[15:52:53] <mozmck> oh, I see :)
[15:52:57] <mozmck> missed that
[16:04:45] <andypugh> Oh how “Straight feed in concave corner can not be reached without gouging” frustrates me!
[16:05:15] <andypugh> Especially as my profile is an external hexagon, fully devoid of concave corners.
[16:15:03] <cradek> andypugh: are you sure you're on the correct side of it?
[16:25:29] <Deejay> gn8
[17:08:26] <Jymmm> If I have to replace the tube it's $1200. If the controller board need to be repaired, it's a $250 flat rate fee. *sigh*
[17:10:16] <MrHindsight> heh
[17:10:40] <Tom_itx> how much is a new unit?
[17:10:59] <MrHindsight> >$30K for the whole thing
[17:11:01] <Jymmm> New replacement cpu board is $1692
[17:12:31] <MrHindsight> dual 8051's, must have liked them
[17:13:33] <MrHindsight> embedded controls and laptop EC's
[17:14:29] <Jymmm> 8051?
[17:14:31] <XXCoder1> hy all
[17:15:12] <MrHindsight> the 80c320's are based on the 8051
[17:15:36] <Jymmm> MrHindsight: what are you talking about?
[17:16:13] <MrHindsight> Jymmm: the microcontrollers on your board
[17:17:14] <Jymmm> where?
[17:18:51] <Jymmm> oh
[17:19:05] <Jymmm> I never saw any '8051" =)
[17:19:10] <MrHindsight> DS80C320 one on each side
[17:19:32] <Jymmm> I see now that you gave the RIGTH number =)
[17:19:44] <Jymmm> (literally)
[17:19:48] <Jymmm> =)
[17:20:04] <MrHindsight> http://www.maximintegrated.com/datasheet/index.mvp/id/2955
[17:20:47] <Jymmm> ah, clones
[17:21:09] <MrHindsight> well 8051 instruction set and pins
[17:21:32] <Jymmm> Why would you need a uC when you have FPGAs?
[17:21:36] <MrHindsight> there were a zillion variations with size of memory, cache and peripherals
[17:21:55] <MrHindsight> those are old fpga's only 6k gates
[17:22:15] <Jymmm> but still
[17:22:58] <MrHindsight> looks like one handles buffering the files and the other is for motion
[17:23:00] <Jymmm> maybe that's why there are two pairs
[17:23:40] <Jymmm> Ok, the foga on the right is going to the motor controller board
[17:23:40] <MrHindsight> there's an external uart near the one on the left
[17:23:43] <Jymmm> FPGA
[17:24:11] <andypugh> cradek: By moving the starting point so that the entry move makes a left turn I seem to have made it happy. I do rather think that the gouging warning was incorrct though. A rapid to X20 Y0 / G42 / G0 @3.349 ^0 was the problem.
[17:24:34] <Jymmm> the fpga on the left appears to be connected to the parapor and I'll assume serial port as well as the grey connector which I forget what its for atm
[17:25:06] <MrHindsight> one probably talks to your PC
[17:25:20] <MrHindsight> and the other handles the motors and laser
[17:25:23] <Jymmm> MrHindsight: There is no PC
[17:25:32] <Jymmm> MrHindsight: You PRINT to the laser directly.
[17:26:04] <MrHindsight> Jymmm: from your smartphone? :)
[17:26:11] <Jymmm> MrHindsight: I have a ethernet to parallel printer server on it right now =)
[17:26:30] <Jymmm> MrHindsight: You could if you can install the print driver on your phone =)
[17:26:54] <MrHindsight> are you going to send the board in?
[17:27:38] <Jymmm> Not yet, I want to isolate the problem first. For all I know it could be a bad cable
[17:28:21] <Jymmm> I need a scope, I wonder if 35MHz would be fast enough?
[17:29:54] <brumby> Hi to all. I have a problem. When using the installed Livecd in the computer I can't see the x,Y and Z-Values in the simulation window from axis. (The Values are just in the DRO-Tab) I just can see the black background from the Textfield cover the simulation lines. When I connect to the linuxcnc box with ssh -X I can see the values in the simulation-tab. Can anybody give me some advice? Is there a font problem with my live cd installation?
[17:31:08] <MrHindsight> brumby: what video card?
[17:32:07] <MrHindsight> any other graphics look funny?
[17:32:21] <brumby> I think it is builtin one in the linuxcnc-box. Shall I look for the chipset?
[17:33:16] <MrHindsight> just wondering if it's a driver problem or of X is acting up
[17:33:41] <Jymmm> MrHindsight: ?
[17:33:47] <MrHindsight> posting a screen shot wouldn't hurt either
[17:33:57] <MrHindsight> brumby: ^^

[17:39:29] <brumby> Every ohter display is fine, just the textbox in the simulation window is without the position texts.
[17:40:44] <MrHindsight> $ glxinfo will tell you which driver was installed
[17:41:58] <brumby> is it possible to run it over the ssh connection or have i to sit in front of the box for glxinfo
[17:42:13] <MrHindsight> OpenGL renderer string: Gallium 0.4 on AMD ARUBA is what is running on mine
[17:42:41] <MrHindsight> as long as you are running it on the server, not on the local machine
[17:43:52] <MrHindsight> that's an old VIA chipset so I'm guessing it's the VESA driver
[17:44:21] <MrHindsight> not really sure what ubuntu did with 10.04 for those old boards
[17:44:32] <brumby> mine says Software rastrerizer 2.1 Meza 7.7.1 or is this th wrong string?
[17:44:46] <MrHindsight> software mesa
[17:45:18] <MrHindsight> might be just some VIA quirk
[17:45:23] <brumby> sure: Mesa
[17:45:57] <brumby> That means, that I have to try another video card?
[17:46:20] <MrHindsight> wow km266
[17:46:30] <MrHindsight> ia that board from ~2000
[17:47:11] <brumby> could be, because I collectetd a lot of old computers...
[17:47:54] <MrHindsight> AGP and PCI
[17:48:03] <MrHindsight> try some other gpu card
[17:48:39] <MrHindsight> http://www.via.com.tw/en/products/chipsets/legacy/km266/
[17:50:30] <brumby> Ok, I will give it a try with another videocard. what means km266, I don't understand. Is this the chipset in my box?
[17:50:57] <MrHindsight> the gpu core in the chipset anyway
[17:51:28] <brumby> And this one seams to old?
[17:52:12] <Einar1> Jymm: I would try changing all the tantalum caps. It seems like the drive to the laser is unstable. They are cheap and easy to desolder - resolder. If you don't have a talon, two soldering irons is fine. With one it's not so gentle on the PCB.
[17:54:48] <Jymmm> Einar1: which ones are the tantalum caps?
[17:55:45] <SpeedEvil> Tantalum through-hole caps?
[17:55:54] <Einar1> The big yellow ones. Be aware they are polarized! There's a black (brown) band on positive.
[17:56:11] <Einar1> No. They are surface mounted.
[17:56:17] <SpeedEvil> Preheat.
[17:56:26] <SpeedEvil> Place the board in an oven at 100C beforehand
[17:56:34] <Einar1> One of them is C41.
[17:56:35] <SpeedEvil> this will make desoldering way easier
[17:57:39] <Einar1> That puts unnecessary stress on all the solderings. I never do. But I use a talon. http://www.newark.com/metcal/mx-talon/soldering-tool-handpiece/dp/77M9250
[17:57:52] <brumby> MrHindsight: Ah yes, On the website I you listed it's an athlon processor. Thanks for your ideas. I'll try another video card.
[17:58:45] <Jymmm> Einar1: do tantilum caps "short" when they are going bad?
[17:59:08] <SpeedEvil> Jymmm: yes
[17:59:09] <SpeedEvil> Often
[17:59:23] <Jymmm> SpeedEvil: smt too?
[17:59:26] <SpeedEvil> yes
[17:59:52] <andypugh> But maybe only briefly.
[18:00:10] <SpeedEvil> Depends on the power of the circuit
[18:00:14] <SpeedEvil> they can short then explode
[18:00:16] <andypugh> (I think the ones on my 12V regulator board exploded today)
[18:00:24] <Einar1> I'd say sometimes. I have seen them go completely short, like a wire, or just loosing capacitance.
[18:00:53] <Jymmm> andypugh: Einar1 says one like C41 here http://i61.tinypic.com/153lhtc.jpg
[18:01:32] <Einar1> Yews, that's one of them. I just mentioned it so you can see what they look like.
[18:01:52] <Jymmm> Einar1: No, that's fine. Is that an alternative replacement?
[18:02:33] <andypugh> The board was one of these: http://www.ebay.co.uk/itm/131167623570 Luckily I have spares.
[18:02:34] <Einar1> ?? There is a value on them. Capacitance and voltage rating.
[18:02:54] <Jymmm> Einar1: I meant in stead of tantilium
[18:03:24] <Jymmm> andypugh: that pic is my laser control board that might be fubar
[18:03:47] <andypugh> I wouldn’t want to guesss if that is tantalum or ceramic.
[18:04:01] <Einar1> Yes, but I would use exactly what is there.
[18:04:10] <andypugh> Tantalum are polarised. And it’s hard to tell the polarity of SMT chips
[18:04:46] <Einar1> The yellow ones are tantalums. There's a + sign on the PCB. And a band on one end. Usually also one end is chamfered.
[18:05:35] <Jymmm> http://en.wikipedia.org/wiki/File:Polarity-rectangular-chips.jpg
[18:06:20] <Jymmm> C41 looks like it's 106C
[18:06:23] <Einar1> ---> http://no.farnell.com/kemet/t543d106k050ahw090/cap-tantalum-10uf-50v-2917/dp/2406595?in_merch=New Products&in_merch=Omtalte nye produkter&MER=en-me-sr-b-all
[18:06:45] <Einar1> Ahh.. Copy - Paste. Sorry.
[18:06:57] <Jymmm> it came thru enough
[18:07:13] <andypugh> How much!
[18:07:49] <Jymmm> $15 USD
[18:07:58] <Jymmm> http://www.newark.com/kemet/t543d106k050ahw090/cap-tantalum-10uf-50v-2917/dp/52X6421?ost=T543D106K050AHW090
[18:08:24] <Einar1> ----> http://www.farnell.com/datasheets/1732749.pdf
[18:09:14] <Jymmm> $15 * 7 = $105 + me doing it... I'd pay the $250 flat rate fee and let the facory repair it
[18:09:35] <Jymmm> If THEY fuck it up, they fix it =)
[18:10:56] <Einar1> ????? 15USD !!! No way. They should be like 0.3USD.
[18:11:59] <Jymmm> whats 106, 100pF ?
[18:12:54] <andypugh> This is a 10uF that is much cheaper: http://uk.rs-online.com/web/p/tantalum-capacitors/7435585/
[18:12:55] <Einar1> That 15$ price is for tape and reel. If you ask for a reel of 7 someone will laugh.
[18:13:34] <Einar1> I forgot once and got a reel of 200. And felt pretty stupid!
[18:17:19] <Einar1> Markings --> http://alasir.com/reference/kemet_tantalum_capacitors/
[18:17:49] <Einar1> So 106 should be 10uF.
[18:17:56] <Jymmm> k
[18:18:41] <Jymmm> http://www.mouser.com/ProductDetail/AVX/TPMD106M050R0140/?qs=mRkWMvdT7ZKB32WqKe9uTA==
[18:19:21] <Jymmm> $108 for 10 pcs, not 10 rolls
[18:20:58] <Einar1> Check the size. High voltage rating and capacitance will be bigger and not fit the board.
[18:21:25] <Jymmm> I'll verify size before ordering.
[18:23:51] <Einar1> And voltage. Use what's already on the board.
[18:25:33] <Einar1> They are probably glued to the board, so need a nudge to get off after solder is flowing.
[18:26:37] <Einar1> You can also use a needle to pry the lead up when solder is flowing.
[18:27:00] <Einar1> Needle between leg and body of capacitor.
[18:27:59] <Einar1> Find a scrap board from anything as training.
[18:30:36] <SpeedEvil> Cutting the leads can be of use
[19:01:36] <zeeshan> 150 ipm doesnt seem safe
[19:01:37] <zeeshan> on the lathe
[19:01:38] <zeeshan> lol
[19:03:00] <zeeshan> http://www.youtube.com/watch?v=9fOiCcQtWO0
[19:04:32] <XXCoder1> just 150 ipm? ;)
[19:04:42] <zeeshan> haha
[19:04:46] <zeeshan> id prolly run it to 100 ipm
[19:04:53] <zeeshan> 150 ipm seems unnecessary
[19:05:30] <XXCoder1> good to see your machine actuallu rimmomg
[19:05:32] <XXCoder1> running
[19:05:38] <zeeshan> rimming
[19:05:38] <zeeshan> lol
[19:05:50] <XXCoder1> I see your crappy hack of using clamp on one end lol
[19:05:57] <zeeshan> haha
[19:06:06] <zeeshan> i dont have any m6x1x85mm socket head cap screws
[19:06:07] <zeeshan> =[
[19:06:11] <zeeshan> need to get some
[19:06:27] <XXCoder1> I definitely need screws when I'm ready to build.
[19:06:34] <XXCoder1> Im still waitinf for screws
[19:06:38] <XXCoder1> ballscrews
[19:06:42] <zeeshan> dude
[19:06:49] <zeeshan> i dont even have the nut tightened down
[19:06:53] <zeeshan> on the fixed end
[19:06:56] <zeeshan> for the z-axis
[19:07:00] <zeeshan> and im getting 3 thou of backlash
[19:07:05] <zeeshan> its prolly cause the entire screw is moving
[19:07:21] <zeeshan> once i have the ball screw shield made, illl clean it all up
[19:07:26] <zeeshan> and tighten/preload it
[19:07:30] <zeeshan> should fix it
[19:07:42] <XXCoder1> lol yeah
[19:07:47] <zeeshan> im impressed by these linearmotion bearing screws
[19:07:48] <zeeshan> theyre awesome
[19:07:58] <XXCoder1> 3 thousandth = 0.003" correct?
[19:08:01] <zeeshan> yes
[19:08:08] <XXCoder1> ok
[19:08:11] <zeeshan> i've had the whole assembly off the lathe
[19:08:14] <zeeshan> and mounted with clamps
[19:08:22] <zeeshan> it had 0 back lash on the 0.0005 resolution indicator
[19:08:32] <zeeshan> so im pretty confident its cause i dont have the nut at the end..
[19:08:54] <zeeshan> also the coupler might be slipping
[19:09:04] <zeeshan> cause i dont have a flat milled out on the ball screw end yet..
[19:11:37] <XXCoder1> ok
[19:11:48] <zeeshan> which size ball screws did you order from em?
[19:11:48] <XXCoder1> I'm so bored waiting for parts kik
[19:12:00] <XXCoder1> 300mm 2x 600mm
[19:12:05] <zeeshan> i got my ball screws in 7 days
[19:12:08] <zeeshan> from china!
[19:12:08] <zeeshan> :P
[19:12:19] <XXCoder1> hope mines that fast too.
[19:12:27] <zeeshan> if its standard length stuff
[19:12:30] <zeeshan> itll be fast
[19:12:37] <XXCoder1> Still not sure how to mount motors since I dont have any metal plates to use
[19:12:53] <XXCoder1> unsure if wood is strong enough for that
[19:13:04] <zeeshan> nah
[19:13:06] <zeeshan> will flex :P
[19:13:10] <zeeshan> actuyally
[19:13:14] <zeeshan> what torque steppers?
[19:13:34] <XXCoder1> http://www.ebay.com/itm/3Axis-Nema23-Stepping-Motor-110N-cm-3-0A-4wire-board-TB6560-Power-for-CMC-mill-/281188392513?pt=LH_DefaultDomain_0&hash=item4178225e41
[19:14:07] <zeeshan> 155 oz-in steppers
[19:14:14] <zeeshan> i bet you can make em out of wood just fine
[19:14:23] <zeeshan> not mdf particle board shit
[19:14:25] <zeeshan> like real wood
[19:14:32] <zeeshan> plywood would work
[19:14:32] <XXCoder1> yeah I plan to get lot scrap wood
[19:14:40] <XXCoder1> my work has em :D
[19:14:50] <zeeshan> i'd honestly order nema23 mounts..
[19:14:53] <zeeshan> the only reason i built some
[19:14:54] <XXCoder1> I plan use plywood for some parts like router holder
[19:14:58] <zeeshan> was i couldnt find nema34 mounts
[19:15:02] <zeeshan> but nema23 theres a lotta options
[19:15:14] <XXCoder1> looking
[19:15:18] <zeeshan> theres some on ebay
[19:15:35] <zeeshan> http://www.ebay.com/itm/For-57mm-NEMA23-Stepper-Motor-Alloy-Steel-Mounting-Bracket-/321352619352?pt=LH_DefaultDomain_0&hash=item4ad21bd558

[19:16:10] <zeeshan> or you can go super strong
[19:16:11] <zeeshan> with those
[19:16:22] <XXCoder1> That includes space for antibacklash
[19:16:23] <zeeshan> its double the price though ;p
[19:16:29] <XXCoder1> seems overlkill tho
[19:16:38] <zeeshan> well with the second mount
[19:16:39] <XXCoder1> maybe when I build better cnc
[19:16:41] <zeeshan> all you gotta do is drill holes
[19:16:46] <zeeshan> in whatever
[19:16:48] <zeeshan> and attach em
[19:16:49] <zeeshan> and youre done

[19:18:22] <XXCoder1> nice eh
[19:18:38] <zeeshan> yea
[19:19:00] <zeeshan> you sure you need such huge lead screws?
[19:19:04] <XXCoder1> I guess orange spots is place I inject grease
[19:19:08] <zeeshan> no
[19:19:19] <zeeshan> those are the ball returns
[19:19:22] <XXCoder1> details is so hard to find.
[19:19:23] <XXCoder1> ahh
[19:19:28] <zeeshan> the golden thing is the grease nipple
[19:19:35] <XXCoder1> cool
[19:19:51] <XXCoder1> it was only kit that has those size
[19:19:56] <XXCoder1> so yes I guess lol
[19:20:07] <XXCoder1> it was bit cheaper when I bought it
[19:24:33] <XXCoder1> HMM

[19:26:26] <XXCoder1> 3 for less than $20 each
[19:26:35] <zeeshan> that is so cheap
[19:26:39] <zeeshan> considering how much it costs to make em
[19:27:26] <XXCoder1> yeah, probably will buy
[19:28:25] <XXCoder1> damn he dont also sell antibacklash coupler

[19:36:12] <XXCoder1> price is high though
[19:36:17] <XXCoder1> yet to find any alum ones
[19:50:42] <Tom_itx> aluminum probably wouldn't be stiff enough in that configuration
[19:50:58] <Tom_itx> stp-si might have em
[19:51:06] <Tom_itx> sdp-si *
[19:52:20] <zeeshan> Tom_itx: what about stainless?
[19:57:32] <MrHindsight> every time I've tried those cheap couplings, mounts, bearings I've been disappointed
[19:58:24] <MrHindsight> I end up taking parts off of older parker and similar actuators to beef it up
[19:58:38] <zeeshan> MrHindsight: can you recommend one for me?
[19:58:45] <Tom_itx> i used solid couplings on mine
[19:58:46] <zeeshan> i have the aluminum shit style coupler
[19:58:57] <zeeshan> lol tom
[19:59:08] <renesis> haha my taig has hollow plastic tube couplers
[19:59:10] <zeeshan> a little fiex is good :P
[19:59:13] <renesis> 4 tiny tubes per axis!
[19:59:14] <zeeshan> renesis!!!!!!!11
[19:59:14] <zeeshan> renesis!!!!!!!11
[19:59:15] <zeeshan> :D
[19:59:16] <renesis> wat
[19:59:18] <zeeshan> hi
[19:59:20] <renesis> hi
[19:59:23] <zeeshan> nice to see you here
[19:59:29] <Tom_itx> never had any problems... you need to get them aligned
[19:59:39] <renesis> i forgot i joined!
[19:59:43] <renesis> was surprised to be here
[19:59:49] <Tom_itx> hose clamp a rubber hose in there if you want flex
[20:00:34] <zeeshan> Tom_itx: how long did you run whatever you were running
[20:00:38] <zeeshan> w/ a solid couling
[20:00:43] <Tom_itx> it's still running
[20:01:21] <Tom_itx> i've had it for probably 20 yrs or so
[20:01:32] <Tom_itx> in various forms
[20:01:38] <Tom_itx> upgraded a time or two
[20:02:15] <zeeshan> Tom_itx: see i was thinking running a solid coupling
[20:02:27] <zeeshan> by first mounting the motor and ball screw toghether
[20:02:34] <Tom_itx> you gotta get them aligned if you do
[20:02:46] <zeeshan> and then seeing where it naturally where the stepper sits
[20:02:54] <zeeshan> account for gravity
[20:03:05] <zeeshan> and then bolt it on the stepper bracket by shimming it accoridngly
[20:03:14] <zeeshan> is that how you kind of did it?
[20:04:25] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/Boxes/milling1.jpg
[20:04:58] <zeeshan> what am i looking at
[20:05:12] <Tom_itx> my sherline
[20:05:12] <zeeshan> my brackets arent that style :P
[20:05:15] <Tom_itx> with steppers
[20:05:25] <Tom_itx> so?
[20:06:25] <zeeshan> itll be harder to align
[20:06:56] <Tom_itx> test run: https://www.youtube.com/watch?v=XhU7S8kifJ4&feature=youtu.be
[20:07:30] <Tom_itx> actually cutting something: https://www.youtube.com/watch?v=-CEqokrtFI4&feature=youtu.be
[20:08:12] <Tom_itx> those were tests of my new steppers / PSU / Gecko drivers
[20:09:37] <renesis> tom_itx: thats standard step mounting for sherlines?
[20:10:18] <Tom_itx> it's not sherline's but quite similar i think
[20:10:42] <renesis> that thing makes my taig look huge
[20:11:17] <Tom_itx> i've done quite a bit with it but it *is* limited
[20:12:53] <XXCoder1> Tom_itx: got links?
[20:13:14] <Tom_itx> to what?
[20:13:38] <XXCoder1> couplers on sale. ebay or amazonm>?
[20:14:00] <Tom_itx> no, i wasn't looking for any
[20:14:13] <XXCoder1> lol I am
[20:14:22] <XXCoder1> its one of few parts I still need
[20:16:51] <XXCoder1> Think I just need 3 zero backlash couplers, nema 23 mounts, and some of those screws
[20:18:20] <jdh> I got oldhams from mcmaster
[20:24:43] <zeeshan> jdh
[20:24:45] <zeeshan> i have power
[20:24:50] <zeeshan> I WIN!
[20:25:49] <Jymmm> zeeshan: Shave your head
[20:25:56] <zeeshan> why
[20:26:04] <Jymmm> no more power
[20:26:26] <tjtr33> zeeshan, re: " 5" diameter circle out of ss 304" consider making a punch & die?
[20:26:41] <zeeshan> tjtr33: yes i did
[20:26:53] <zeeshan> shearing will cause residual stresses at the shear interface
[20:27:01] <zeeshan> so i cant do that either
[20:27:17] <tjtr33> so will a spinning cutter, but you can judge
[20:27:33] <zeeshan> less than shearing
[20:27:37] <Jymmm> zeeshan: http://wiki.answers.com/Q/Who_is_the_greek_god_got_his_power_from_his_hair
[20:28:01] <zeeshan> haha Jymmm, now i get it
[20:28:59] <Jymmm> zeeshan: these are evil but will cut a 5" hole http://www.ebay.com/bhp/saw-circle-cutter
[20:29:13] <zeeshan> Jymmm: yea man
[20:29:16] <zeeshan> thats what im thinking
[20:29:23] <zeeshan> just with a boring head instead so its more rigid
[20:29:33] <zeeshan> those circle cutters make nice projectiles when they break :P
[20:29:37] <malcom2073> Hi scooty_puff
[20:29:44] <scooty_puff> sup
[20:35:46] <scooty_puff> what are 8 wire steppers? are they just like 4 wire but with 4 coils?
[20:36:14] <cradek> yep
[20:36:21] <cradek> split each coil in half
[20:36:24] <XXCoder1> those is called 4 phase right?
[20:36:27] <zeeshan> http://www.esuli.it/wp-content/uploads/2011/10/stepperWiring.png
[20:36:28] <cradek> no
[20:36:42] <cradek> the idea is you can put those pairs in series or parallel
[20:36:43] <XXCoder1> oh
[20:37:11] <zeeshan> http://probotix.com/stepper_motors/unipolar_bipolar/
[20:37:14] <zeeshan> this is a very simple site
[20:37:17] <zeeshan> that made me understand it
[20:37:23] <zeeshan> shows the benefits..
[20:37:33] <zeeshan> basically you end up finding out that you want bipolar paralle :d
[20:37:38] <zeeshan> for most torque!
[20:41:55] <Jymmm> http://www.smithsonianmag.com/science-nature/the-microscopic-structures-of-dried-human-tears-180947766/?no-ist
[20:44:01] <scooty_puff> what are hybrid steppers?
[20:44:38] <zeeshan> https://www.youtube.com/watch?v=u12dt1RqLW0
[20:49:09] <PetefromTn_> Just what the hell is a scooty puff? hehe
[20:55:34] <scooty_puff> PetefromTn_: its from futurama
[20:57:06] <PetefromTn_> what's futurama?
[20:57:18] <Jymmm> animated tv show
[20:57:21] <PetefromTn_> googling
[20:57:50] <scooty_puff> an awesome cartoon that got canceled :(
[20:59:12] <PetefromTn_> huh...some kinda animated rocket. just bustin yer chops man LOL
[21:03:26] <zeeshan> hey PetefromTn_
[21:03:29] <zeeshan> hows work going
[21:04:45] <XXCoder1> yo
[21:29:44] <PetefromTn_> Sorry had to go take care of something..
[21:29:52] <PetefromTn_> It's okay.
[21:30:07] <PetefromTn_> I am now off for the summer with my kids working back in my own shop.
[21:40:54] <jdh> making anythign good?
[21:46:40] <scooty_puff> what is the deal with this irc channel? is it people who like linux who also like cncs? or people who use embedded linux to run cncs? ...
[21:47:01] <scooty_puff> what is the connection?
[21:47:44] <toastydeath> the latter
[21:48:12] <toastydeath> and general machining discussion
[21:48:49] <PetefromTn_> I am making some cool stuff but I managed to smoke my 7i77 card and right now I am trying to get it fixed. got a brand new one overnighted here this afternoon.
[21:48:50] <XXCoder1> scooty_puff: linuxcnc is orogram to control cncs
[21:49:05] <XXCoder1> oddly we talk about cncs more than program here...
[21:49:18] <XXCoder1> diycnc is very dead
[21:49:29] <XXCoder1> *#diycnc channel
[21:49:32] <PetefromTn_> and we talk about basically anything that pops up quite often as well ;)
[21:50:38] <scooty_puff> this is random but i am in the process of writing my own cnc control program for a atmega644
[21:50:53] <scooty_puff> wierd i just stumbled in here
[21:51:26] <PetefromTn_> These guys could probably figure out how to run linuxCNC on about anything... Even a saltine cracker I think.
[21:52:27] <PetefromTn_> There are already some guys working with arduinos and beagle bone black stuff with linuxCNC.
[21:53:00] <PetefromTn_> altho I admit I don't know SQUAT about that stuff.
[21:54:56] <jdh> it has been done. do you want to do it just for the sake of doing it or do you have some specific application?
[21:55:26] <PetefromTn_> http://knoxville.craigslist.org/tls/4480527544.html Neat old Logan lathe for sale.
[21:55:36] <scooty_puff> i know it has been done
[21:55:42] <scooty_puff> i just want to make my own
[21:55:50] <jdh> good enough reason.
[21:56:59] <scooty_puff> i want to eventually strap a yag laser on to it
[21:58:39] <scooty_puff> like 2-40 watt and pulse it as fast as i can get it to go
[21:58:40] <jdh> you could strap a yak on it for testing. might do less damage.
[21:58:53] <scooty_puff> *20-40
[22:24:37] <XXCoder1> jdh: yeah this yak! http://www.animalstown.com/animals/y/yak/wallpapers/yak-wallpaper-4.jpg
[22:24:40] <CaptHindsight> tjtr33: http://www.pbclinear.com/ ever buy from them out in Rockford
[22:27:00] <CaptHindsight> scooty_puff: have you seen http://www.linuxcnc.org/ ?
[22:27:23] <XXCoder1> huh?? http://www.pbclinear.com/Linear-Plain-Bearings-with-Simplicity-Maintenance-free-Liner
[22:27:31] <XXCoder1> it looks like its for SBR rails
[22:27:36] <XXCoder1> but no balls?
[22:27:44] <CaptHindsight> XXCoder1: the plain bearings are polymer bearings
[22:27:55] <CaptHindsight> yeah no balls
[22:28:04] <XXCoder1> better? worse?
[22:28:30] <CaptHindsight> their polymer bearings are better than Chinese sbr ball bearings
[22:28:46] <CaptHindsight> watch the video... hold a sec...
[22:28:53] <XXCoder1> they do have 12 16 and 20. I has those sizes.
[22:29:05] <XXCoder1> problem is im not sure of external dim
[22:29:14] <CaptHindsight> http://www.pbclinear.com/Videos/All/Bearing-Selection-Criteria
[22:29:35] <CaptHindsight> XXCoder1: in fact you might want to watch the whole series
[22:30:09] <XXCoder1> Video not found or access denied: http://d1qrpw5n71yojo.cloudfront.net/Linear Learning Center Bearing Selection_1.flv
[22:30:19] <tjtr33> CaptHindsight, those slides look pretty good, thx for the link
[22:30:52] <CaptHindsight> tjtr33: I was looking for Chinese linear bearings and they turned up in the search :)
[22:31:22] <tjtr33> the simo series look like real tools
[22:31:49] <XXCoder1> I probably will just use cleaned up chinese bearings
[22:31:55] <XXCoder1> good enough for now
[22:31:56] <tjtr33> hey i got that hurco running, took 1st cuts today
[22:32:01] <CaptHindsight> I'm checking into their lead times, the prices look good
[22:32:15] <XXCoder1> its my frame that will have worse effects on precision than bearings.
[22:33:20] <CaptHindsight> tjtr33: they machine their extrusions to 0.002" for flatness
[22:33:49] <tjtr33> "3 bearing tribologies" ?? jinglish or trilobites ?
[22:33:54] <XXCoder1> capt how o you find out prices?
[22:34:17] <tjtr33> .002" hmm not as good as the rail
[22:34:59] <CaptHindsight> http://www.pbclinear.com/Download/WhitePaper/Profile-Rail-vs-Integral-V.pdf?utm_source=tech_insight&utm_medium=news&utm_content=july&utm_campaign=IVT-vs-Profile-Rail
[22:35:51] <CaptHindsight> XXCoder1: call or email
[22:35:57] <XXCoder1> ok
[22:37:35] <CaptHindsight> https://www.youtube.com/watch?v=csru_NMVKTk too bad they used a glue gun for the demo
[22:38:09] <XXCoder1> it begtter not be handheld
[22:38:20] <XXCoder1> good.
[22:38:36] <XXCoder1> those definitely is nice rails.
[22:39:16] <CaptHindsight> it's funny when you can just send them a sketch and have them design and give you a BOM in 1 day where the repcrap makers take months to come up with wobbly stages
[22:39:32] <XXCoder1> well
[22:39:35] <XXCoder1> more money
[22:39:58] <CaptHindsight> any machine designer can slap together a glue gun or dlp printer in an afternoon
[22:40:21] <XXCoder1> if I ever decide to make 3d pinter
[22:40:23] <tjtr33> the tall form ball bearing rail & ball screw , it sez 3m/s max vel! 250/m^2 acc hard to believe on an alum extrusion base
[22:40:23] <XXCoder1> printer
[22:40:30] <CaptHindsight> XXCoder1: automation parts are like legos
[22:40:37] <XXCoder1> I would make it use milk gallon jugs plastic
[22:40:51] <XXCoder1> I'll have infinite free plastic
[22:40:53] <tjtr33> but i'll go out there if they can handle a project i got
[22:41:34] <XXCoder1> lol with 8020 sure
[22:41:45] <XXCoder1> too bad I'm not using em lol
[22:42:04] <tjtr33> machine tools should be like legos, what do you do when the contract is over? take it apart, put parts on shelf, reconfig for next job run
[22:42:15] <CaptHindsight> XXCoder1: you can download 3d models of most automation components and layout a 3-5 axis system in a few hours
[22:42:41] <CaptHindsight> it's not a several weeks or months project
[22:42:42] <XXCoder1> I tried sketchup
[22:43:09] <XXCoder1> I dont understabd it really. also I cant resize or place parts by coorditate after its been placed :(
[22:43:27] <tjtr33> hey my sketchup seems to have expired, insisted i upgrade 8 to 2014. and 2014 wont run under wine :(
[22:43:32] <CaptHindsight> NX, Catia, Creo, Solidworks
[22:43:51] <XXCoder1> tjtr33: so no timer hacks?
[22:44:02] <tjtr33> didnt see any hooks
[22:44:23] <XXCoder1> make your system lie about date?
[22:45:09] <tjtr33> and i can/could place components to specific posns ( oh, chg the sys clock ? no , didnt try )
[22:45:51] <XXCoder1> or some hack software that injects sysdate reply to sketch
[22:46:27] <tkayca> Earlier on, I was able to get +/-10V out of my 7i49, now it seems if i try and jog I'm getting millivolts watching with a multimeter. Could I get help troubleshooting?
[22:46:36] <CaptHindsight> tjtr33: ever come across an end of arm tool for snipping light wire 30ga and smaller or thread, filament, kevlar, carbon fiber etc??
[22:47:43] <CaptHindsight> http://www.sasgripper.com/products/nipit/nipit_sn.htm but smaller
[22:47:49] <tjtr33> no, but i followed your japanese suggestion, very cool end effectors at snipit, never saw such b4
[22:47:58] <tjtr33> nipit
[22:48:17] <CaptHindsight> heh and the industrial dog trimmer :)
[22:48:22] <tjtr33> micro pneumatic jaws of life
[22:49:55] <tjtr33> still reading that pbclinear catalog
[22:50:25] <CaptHindsight> https://www.sullivansupply.com/cart/ia/p-665-oster-510-shearmaster-clipper-with-blades.aspx
[22:50:41] <CaptHindsight> interesting that they are nearby
[22:50:57] <tjtr33> like ozzie sheep shears?
[22:51:00] <CaptHindsight> they don't do a very good job of advertising
[22:51:57] <tjtr33> wow that was Oster
[22:52:27] <CaptHindsight> blenders and sheep shears
[22:53:29] <tjtr33> wahl?
[22:54:05] <CaptHindsight> I just want to cut a single fiber, but very tough fiber
[22:54:23] <Jymmm> CaptHindsight: what type of fiber?
[22:54:23] <XXCoder1> superman's hair? lol
[22:54:26] <XXCoder1> jk
[22:54:35] <tjtr33> www.sheepshear.com and maybe veterinarian power toe clips
[22:54:53] <CaptHindsight> kevlar, steel wire 30ga and smaller, carbon, etc etc
[22:55:05] <Jymmm> CaptHindsight: Pick ONE
[22:56:04] <Jymmm> use those german sounding ones, red handle
[22:56:36] <CaptHindsight> preferably electric vs pneumatic, small and light as possible
[22:59:10] <XXCoder1> sigh, just watched handheld video
[22:59:44] <XXCoder1> My brain sucks
[23:00:09] <XXCoder1> laters gonna lay down to recover, its but early but Im tired enough to sleep anyway lol laters

[23:02:20] <CaptHindsight> Jymmm: http://www.sasgripper.com/products/nipit/nipit_SNP.htm
[23:02:47] <CaptHindsight> Jymmm: the machine has to cut it
[23:02:55] <CaptHindsight> machine/robot
[23:03:01] <Jymmm> ah
[23:03:42] <Jymmm> hope that has replaceable blades
[23:03:47] <revo14> hello how I should installing linucnc on debian wheezy?
[23:03:57] <CaptHindsight> what version debian are sebs new debs?
[23:04:35] <Jymmm> revo14: Why not install as is fro the LiveCd ISO ?
[23:04:40] <Jymmm> from*
[23:05:01] <revo14> with ubuntu?
[23:05:07] <Jymmm> yes
[23:05:18] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Wheezy_Linux-Rt_Compile_LinuxCNC
[23:06:47] <revo14> i did but i cant have other programs like freecad inkscape etc dont work internet there so i have debian wheezy
[23:07:00] <revo14> i did that http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Lenny_Compile_LinuxCNC
[23:08:17] <CaptHindsight> revo14: why do you need to use Debian?
[23:09:16] <CaptHindsight> and why didn't freecad and inkscape not with with wheezy?
[23:09:23] <tjtr33> CaptHindsight, maybe medical powered forceps like at http://www.depuysynthes.com/hcp/power-tools
[23:09:38] <CaptHindsight> revo14: and why didn't freecad and inkscape not with with wheezy?
[23:10:02] <tjtr33> haha """Anspach XMAX and EMAX 2 Plus devices, achieving 80,000 rpm, helping go through cranial bones like a DeWalt through butter"""
[23:10:41] <revo14> yes I have this progroms here but i wnat to have all here on in ubuntu
[23:10:46] <revo14> no two OS
[23:11:21] <CaptHindsight> revo14: can't you just use Ubuntu for everything?
[23:11:37] <revo14> no
[23:11:45] <CaptHindsight> ubuntu has freecad, inkscape and linuxcnc
[23:11:54] <revo14> dont work internet have try for long time but nothing
[23:11:56] <CaptHindsight> what is missing from ubuntu?
[23:12:14] <revo14> doesnt work
[23:12:19] <CaptHindsight> ah , wireless or wired networking?
[23:13:21] <revo14> wireless and all nothing doesnt workking so i dont now how to do
[23:13:30] <Jymmm> CaptHindsight: FSCK ME, that website is obnoxious with bloat... webtrax, liveperson, and other content
[23:14:25] <tjtr33> revo14, did you ask on #ubuntu to solve your internet connection problem? tell them your chipset
[23:14:55] <CaptHindsight> and now some don't even render in Firefox unless noscript, adaware and flashblock are completely off
[23:15:43] <CaptHindsight> revo14: laptop from Spain by chance? no wired network adapter?
[23:15:51] <revo14> i want to install on debian but no sure how I must do it
[23:16:01] <revo14> yes
[23:16:27] <CaptHindsight> he's been battling with his install for a while
[23:17:01] <CaptHindsight> revo14: have you been able to run the latency test yet on that laptop?
[23:17:20] <CaptHindsight> revo14: this might be lots of work for nothing
[23:17:21] <revo14> yes
[23:17:35] <CaptHindsight> what were your latency numbers?
[23:17:45] <CaptHindsight> <50000?
[23:18:02] <Jymmm> Ok, finally a good use for hot glue gun... https://ca.news.yahoo.com/blogs/good-news/lucky-duck-buttercup-gets-foot-waddles-joy-170220388.html
[23:18:25] <revo14> i did that but im new on linux i did write on terminal but i dont know much
[23:18:48] <CaptHindsight> Jymmm: http://www.3ders.org/articles/20140518-print-intricatedly-designed-pancakes-with-pancakebot-printer.html
[23:19:23] <CaptHindsight> a good use for all those wobbly routers
[23:19:30] <tjtr33> revo14, http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Wheezy_Linux-Rt_Compile_LinuxCNC
[23:19:38] <revo14> in fact when i did that i lose all hdd were delete undertsnad me?
[23:21:22] <CaptHindsight> you lost your file system on the hdd when you ran the latency test?
[23:22:03] <CaptHindsight> how do you know that debian will support your wireless adapter?
[23:22:18] <CaptHindsight> or the connection manager
[23:23:21] <revo14> when i installed debian no problem i didnt nothing
[23:23:37] <revo14> no problem for go to internet
[23:23:46] <revo14> i would like to have linuxcnc here
[23:24:06] <CaptHindsight> revo14: it's probably best that you run the latency test from the linuxcnc live cd first and then tell us the numbers
[23:25:13] <CaptHindsight> revo14, http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Wheezy_Linux-Rt_Compile_LinuxCNC
[23:25:29] <CaptHindsight> those are the only install instructions
[23:25:37] <revo14> can i have port usb? i need some special for that?
[23:26:08] <CaptHindsight> if you want to try you are on your own or you'll just have to ask here or the mail list about your problems
[23:26:35] <CaptHindsight> USB should just work, but not with Linuxcnc
[23:27:13] <CaptHindsight> if that is what you want to do, have Linuxcnc work over USB, that won't work
[23:27:29] <revo14> understand
[23:28:04] <CaptHindsight> revo14: what do you want to control with Linuxcnc?
[23:28:24] <CaptHindsight> stepper motors?
[23:28:34] <revo14> yes
[23:29:16] <CaptHindsight> I didn't see a miniPCIe port on your laptop
[23:29:48] <CaptHindsight> does your laptop have a wired ethernet/network adapter?
[23:30:31] <CaptHindsight> Linuxcnc can't control stepper motors over USB
[23:31:31] <tjtr33> revo14, didyou follow this? http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Wheezy_Linux-Rt_Compile_LinuxCNC ? didyou install Wheezy first? try http://www.debian.org/CD/live/#live-install-stable
[23:31:56] <tjtr33> wheezy=7.5
[23:32:16] <revo14> i have it
[23:33:10] <revo14> yes mi lapto work well on internet but with debian
[23:33:18] <CaptHindsight> ok
[23:33:49] <CaptHindsight> did you try the linuxcnc howto for debian wheezy?
[23:34:03] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Wheezy_Linux-Rt_Compile_LinuxCNC
[23:34:12] <CaptHindsight> revo14: this one ^^
[23:34:15] <Jymmm> https://ca.news.yahoo.com/video/flying-man-soars-washington-160313083.html
[23:34:16] <revo14> no
[23:34:20] <revo14> i did that
[23:34:31] <CaptHindsight> revo14: try that and let us know what happens
[23:34:35] <revo14> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Debian_Lenny_Compile_LinuxCNC
[23:34:49] <CaptHindsight> revo14: that is for lenny
[23:34:51] <tjtr33> lenny??
[23:34:56] <CaptHindsight> not for wheezy
[23:35:04] <tjtr33> ( squiggy :)
[23:35:34] <CaptHindsight> revo14: you need to follow the one for Wheezy
[23:35:41] <revo14> when i did that alot things were installed here how i can delete all that?
[23:37:03] <CaptHindsight> how can we know what you did?
[23:37:24] <CaptHindsight> can you just start over and follow the howto for Wheezy?
[23:37:30] <revo14> understand
[23:37:35] <revo14> i try
[23:37:49] <CaptHindsight> by start over, I mean with a fresh wheezy install
[23:38:44] <revo14> really is very difficukt for me linux is difficult
[23:39:40] <PetefromTn_> Well I managed to get the new 7i77 card I ordered to replace the one I smoked installed in the machine. It seems to be working correctly and the green light turns on and flashes. I went up to the front of the machine and looked at the display and linux ubuntu had loaded and LinuxCNC had autoloaded without an error which I was getting before.
[23:39:46] <PetefromTn_> So that is good news.
[23:39:51] <tjtr33> it is very particular. each step must be done correctly before next step. slow works better :)
[23:40:17] <CaptHindsight> revo14: we have all been through what you are doing before :)
[23:40:25] <CaptHindsight> that's how you learn
[23:40:50] <CaptHindsight> or get fed up and become a Shepard
[23:40:58] <PetefromTn_> Now I need to figure out where I removed a 24v lead off a relay when the power supply burnt up. I am not sure which terminal it went on and I am gonna have to look carefully at my wiring diagram so I don't screw it up.
[23:41:27] <PetefromTn_> I am pretty sure where it goes but I want to MAKE sure before I hook it up and try to energize the servos.
[23:42:32] <PetefromTn_> It is late here now so I am gonna hit the sack and look at it in the morning when I am not so tired.
[23:42:57] <PetefromTn_> With any luck I will be back to machining parts tomorrow afternoon and I can get on with this retrofit.
[23:43:24] <PetefromTn_> Feel like SUCH a dumbass for screwing it up like I did.
[23:43:59] <zeeshan> PetefromTn_: howd the card burn?
[23:44:14] <zeeshan> the other day when i was hooking up the wiring for my lathe
[23:44:20] <zeeshan> i frigging reversed the polarity on the stepper driver
[23:44:21] <zeeshan> lol
[23:44:23] <zeeshan> 72VDC!!
[23:44:31] <zeeshan> it was like that for 5 minutes or so
[23:44:35] <PetefromTn_> I was trying to fix the spindle motor cooling fan setup which I did not realize had been disabled when I converted to modbus spindle control recently.
[23:44:35] <zeeshan> till i realized the drive wasn't powered up
[23:44:49] <zeeshan> luckily it worked after i reversed the polarity
[23:44:50] <CaptHindsight> heh, I've double checked my wiring and still put the 48V on the +5 and the +5V on the 48V
[23:45:25] <zeeshan> PetefromTn_: so you accidently hooked up a power wire
[23:45:28] <zeeshan> where it wasnt supposed to go?
[23:45:32] <PetefromTn_> My friend art was helping me rewire it to come on whenever servos were enabled and I accidentally hooked the wire to the wrong terminal on the relay.
[23:45:34] <CaptHindsight> sometimes you don't see your own mistakes, like proofreading your own writing
[23:45:41] <zeeshan> doh
[23:45:46] <zeeshan> CaptHindsight: i agree
[23:45:47] <zeeshan> lol
[23:45:50] <zeeshan> im used to doing car wiring
[23:46:02] <zeeshan> which isn't usually too damaging
[23:46:05] <zeeshan> if you do something wrong
[23:46:18] <PetefromTn_> Basically I ran 110v into a 24volt relay input and smoked the relay, the 24v power supply and the 7i77 card...
[23:46:18] <zeeshan> (youll find out fast enough!)
[23:46:32] <zeeshan> PetefromTn_: wow
[23:46:39] <PetefromTn_> yup...one stupid wire.
[23:46:41] <zeeshan> im suprised the power supply didnt go into overcurrent protection
[23:46:43] <PetefromTn_> in the wrong place.
[23:46:54] <PetefromTn_> nope it fried.
[23:46:57] <PetefromTn_> Nice light show.
[23:47:03] <zeeshan> what kind of supply?
[23:47:05] <PetefromTn_> lots of smoke.
[23:47:17] <PetefromTn_> linear supply that came in the machine.
[23:47:20] <zeeshan> ah
[23:47:24] <CaptHindsight> zeeshan: speaking of cars, are there any flashing tools for Nissan ECM's besides the factory consult-II?
[23:47:24] <zeeshan> maybe it didnt have overcurrent protection
[23:47:26] <PetefromTn_> it is a heavy duty little bastard.
[23:47:39] <PetefromTn_> but not heavy duty enough apparently to take that abuse.
[23:47:54] <zeeshan> there is nistune CaptHindsight
[23:48:24] <zeeshan> PetefromTn_: oh well
[23:48:25] <PetefromTn_> Pete from mesa thinks I blew the 3.3v regulator on the 7i77 card and that it might be fixable.
[23:48:43] <CaptHindsight> http://home.exetel.com.au/nds/NDSII/index.php?content=supportedcars found this for tweaking just about evrything except for complete firmware replacement
[23:48:52] <PetefromTn_> I am gonna send it to him so maybe if it is I will have two 5i25/7i77 setups here.
[23:49:07] <zeeshan> CaptHindsight: that seems like a scanner
[23:49:09] <zeeshan> never seen it before
[23:49:18] <PetefromTn_> Then I can do a lathe or something with it.
[23:49:18] <zeeshan> PetefromTn_: you dont need 2
[23:49:21] <zeeshan> you can give me one
[23:49:22] <zeeshan> :-)
[23:49:25] <zeeshan> jk
[23:49:42] <PetefromTn_> actually I kinda wish I had two because I could use a backup just in case.
[23:50:00] <PetefromTn_> They are actually pretty cheap.
[23:50:13] <zeeshan> well i didnt know about mesa cards
[23:50:18] <zeeshan> so now i'm stuck with probotix bobs
[23:50:21] <PetefromTn_> I bought another complete 5i25/7i77 combo kit with cable and whatnot.
[23:50:21] <zeeshan> oh well
[23:50:24] <zeeshan> they work for my application
[23:50:25] <tjtr33> make sure your wiring is right before trying this http://speakwisdom.wordpress.com/2012/08/13/243/
[23:50:32] <tjtr33> you might blow your head up
[23:50:48] <zeeshan> CaptHindsight: why do you need to flash a nissan ecu
[23:52:34] <zeeshan> man i am a little sad
[23:52:48] <zeeshan> i missed a machinist tool haul ad by 2 hours 30 minutes
[23:52:55] <zeeshan> he had 208 end mills
[23:53:04] <zeeshan> 3/8 to 1-1/4"
[23:53:08] <zeeshan> 60% brand new
[23:53:08] <CaptHindsight> zeeshan: what did you find for a ballscrew for your carriage?
[23:53:10] <zeeshan> $120
[23:53:11] <zeeshan> :(
[23:53:14] <zeeshan> it got snagged so quick
[23:53:25] <zeeshan> CaptHindsight: i just used an extended ball screw
[23:53:29] <zeeshan> you saw the video right?
[23:53:55] <CaptHindsight> heh, sometimes I've been the first caller moments after a new craigslist post
[23:54:10] <zeeshan> dude, im thinking of writing a code
[23:54:14] <zeeshan> that pops up ALL brand new ads
[23:54:15] <CaptHindsight> you have to hit the refresh button :)
[23:54:18] <zeeshan> related to certain keywords..
[23:54:22] <zeeshan> and text msgs me them
[23:54:24] <CaptHindsight> it's like playing a slot machine
[23:54:35] <zeeshan> https://www.youtube.com/watch?v=9fOiCcQtWO0
[23:54:41] <zeeshan> towards 1:10
[23:54:44] <zeeshan> you can see the ball screw for the X
[23:54:54] <zeeshan> its a retarded way of doing it
[23:54:56] <zeeshan> but it works
[23:55:01] <PetefromTn_> says video has been removed by the user.
[23:55:02] <CaptHindsight> This video has been removed by the user. ?
[23:55:07] <zeeshan> bah
[23:55:53] <CaptHindsight> zeeshan: I'm putting the same one together here tomorrow, but keeping it manual
[23:56:06] <CaptHindsight> I'm just curious
[23:56:33] <CaptHindsight> it's been in parts here for 3 years
[23:57:01] <CaptHindsight> somebody changed gears when it was running so i got it for cheap
[23:57:33] <CaptHindsight> it only had one gear pin sheared off, so 50 cent fix in parts
[23:58:30] <zeeshan> i dunno why it got deleted
[23:58:31] <zeeshan> sigh
[23:58:33] <zeeshan> reuploading
[23:58:40] <zeeshan> haha
[23:58:45] <zeeshan> those shear pins are easy to replace
[23:58:52] <zeeshan> were the brass?
[23:58:55] <zeeshan> or something of the like
[23:58:59] <zeeshan> *they
[23:59:19] <zeeshan> some of the shear pins in my machine are brass
[23:59:21] <zeeshan> some are steel
[23:59:55] <CaptHindsight> rolled steel pin was all
