[05:02:15] <archivist> zeeshan, a toy for you http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=141376268678&ssPageName=ADME:B:SS:GB:3160
[05:23:46] <kfoltman> does it double as A nema34 motor mount? ;)
[08:23:52] <cncbasher> guys anyone have a oneshot timer ?
[08:24:41] <cncbasher> loadrt oneshot count = 1
[08:24:41] <cncbasher>
[08:24:41] <cncbasher> addf oneshot.1 servo-thread
[08:24:41] <cncbasher>
[08:24:41] <cncbasher>
[08:24:42] <cncbasher>
[08:24:42] <cncbasher> #set one shot timer in sec
[08:24:43] <cncbasher> setp onshot.1.width 6
[08:24:43] <cncbasher>
[08:24:44] <cncbasher> net machine-is-enabled => oneshot.1.in
[08:24:44] <cncbasher> net machine-is-on1 <= oneshot.1.out
[08:24:45] <cncbasher> net machine-is-on1 hm2_5i25.0.7i77.0.0.output-07
[08:25:13] <cncbasher> i tried the above without success
[08:25:40] <cncbasher> i need to have a timer to hold the switch on for 6 sec
[08:26:17] <cncbasher> this is using the machine on button and then output to a pin to pull a contactor for 6 sec
[08:26:42] <cncbasher> so where have i gone wrong
[08:28:49] <archivist> halscope the input see if it is triggered
[08:29:36] <archivist> is it edge or level triggered?
[08:29:37] <cncbasher> i seem to get an error in syntax
[08:30:17] <cncbasher> it's using the start button in axis , so i presume level
[08:31:08] <cncbasher> unless i'm looking at this problem the wrong way
[08:31:10] <archivist> the doc says edge
[08:32:04] <archivist> default is trigger on rising edge
[08:43:26] <cncbasher> yea things not working how i presume them to work so may need another route
[08:43:55] <cncbasher> either that or the syntax i am using is wrong
[08:44:09] <archivist> cncbasher, you near Doncaster?
[08:44:33] <cncbasher> abt 70 - 90 north
[08:44:39] <cncbasher> hartlepool
[08:45:49] <archivist> well I remembered north of me, I have a delivery to do on Monday around Doncaster somewhere
[08:46:31] <cncbasher> http://permalink.gmane.org/gmane.linux.distributions.emc.user/40773
[08:49:39] <cncbasher> yea it's about another 45min to an hour further
[08:56:41] <archivist> or one of those 2v4 oneshots designed for control cabinet use
[08:56:47] <archivist> 24v
[10:14:40] <tjtr33> cncbasher, 6secpulse.txt http://pastebin.com/p0cWUhkS oneshot6sec.hal http://pastebin.com/Qx079diQ oneshot1.ui http://pastebin.com/4YrkEYt6
[10:15:03] <tjtr33> gets you a 6 sec pulse on trgr ( the gui is tiny, easy to misplace ;)
[10:15:47] <tjtr33> i had built 2 cascaded oneshots for edm ontime/offtime, and hacked it, runs fine here
[11:33:27] <cncbasher> thanks
[11:33:39] <tjtr33> +*art
[11:37:27] <tjtr33> np
[11:51:25] <IchGuckLive> hi all B)
[12:02:51] <tjtr33> IchGuckLive, are you retired now? congratulations!
[12:03:18] <IchGuckLive> yes
[12:03:26] <Deejay> so you have too much time now?
[12:03:32] <tjtr33> i thought you were offline for 5 years. have fun!
[12:03:57] <IchGuckLive> the phone contract runs till 30th
[12:39:33] <IchGuckLive> not to many post here today
[12:58:35] <IchGuckLive> im off bye
[13:07:51] <zeeshan> archivist: says shipping only to uk :{
[13:10:36] <archivist> its about 30miles from me, I could collect and ship dunno costs though
[13:19:37] <archivist> I like to be able to measure http://www.ebay.co.uk/itm/221518810156 I won
[13:21:29] <zeeshan> 99 cents
[13:21:30] <zeeshan> wow
[13:21:45] <zeeshan> congrads!
[13:27:58] <SpeedEvil> Awesome.
[13:28:12] * SpeedEvil refrains from jokes about rubbers.
[14:46:41] <CaptHindsight> looks like a Durometermometer
[14:48:28] <archivist> different name for the same thing
[14:51:32] <CaptHindsight> archivist: what scale is on it?
[14:51:49] <archivist> dunno till I fetch it
[14:52:31] <archivist> I have a little hand held IRHD one I got from a scrap yard
[14:53:21] <archivist> it says my watch strap is 37 International Rubber Hardness Degrees
[15:23:52] <6JTAA6FBT> any opinions on a "good yet cheap" touch probe?
[15:24:14] <skunkworks> make your own?
[15:24:59] <Loetmichel> its easy
[15:25:29] <Loetmichel> you only need a medium ballbearing, some single sided PCB material and a cnc mill
[15:25:49] <Loetmichel> and a few wires and pins
[15:25:52] <zeeshan> i thought most touch probes had a bit of flex.
[15:26:00] <zeeshan> so you dont crash your spindle
[15:26:11] <Loetmichel> ... and ONE spring
[15:26:20] <skunkworks> yes - they flex by design...
[15:26:21] <zeeshan> theyre cheap buy
[15:26:56] <anarchos> http://www.ebay.com/itm/Touch-probe-cmm-digitizing-renishaw-haas-fadal-cnc-mill-lathe-router-engraver-/161352724525?pt=LH_DefaultDomain_0&hash=item25915f302d
[15:27:04] <Loetmichel> skunkworks: i would opt for an electronic one
[15:27:11] <skunkworks> http://www.pkm.org.ua/2011/07/cnc-touch-probes-review.html
[15:27:20] <zeeshan> anarchos2: are you looking for a digitizing probe
[15:27:25] <zeeshan> or just simple touch probe
[15:27:34] <zeeshan> for setting up work piece coordinate
[15:27:38] <anarchos> well, depending on price i could go either way
[15:27:42] <skunkworks> Loetmichel: what do you mean?
[15:27:50] <zeeshan> a mechanical edge finder is like 10$
[15:27:53] <Loetmichel> skunkworks: like the ebay link
[15:27:54] <zeeshan> and works really well
[15:28:02] <Loetmichel> but selfbuilt
[15:28:12] <anarchos> a digitizing probe would work for finding WPC as well might be nice
[15:28:29] <zeeshan> ive been looking at digitizing probes for inspection
[15:28:29] <zeeshan> :P
[15:28:48] <skunkworks> I agree - a kinematics style are awesome
[15:29:00] <skunkworks> (6 balls - 3 pins)
[15:29:26] <Loetmichel> its really easy, you only need a few ball bearing balls, a pice of PCB with 6 holes, a piece of plastic that holds 3 allen screws with the heads 120° apart and a spring thet presses the plastic into the pcb with the balls
[15:29:35] <Loetmichel> so that the allen screws do the connection
[15:29:41] <Loetmichel> from ball to ball
[15:30:05] <skunkworks> I started to make one - then found a renishaw knockoff on ebay for cheap
[15:30:19] <Loetmichel> then put a ball on hte end of a steel pin, screw it in the opposite side of the plastic pice and voila: Diy reinsahw
[15:30:53] <anarchos> skunkworks, have an url?
[15:31:13] <anarchos> also, what software to use for digitizing?
[15:31:40] <skunkworks> http://electronicsam.com/images/KandT/probe/DSCF1507%5b1%5d.jpg
[15:32:08] <skunkworks> anarchos: linuxcnc does probing/digitizing just fine..
[15:32:15] <anarchos> ah i see
[15:32:17] <anarchos> cool
[15:32:19] <skunkworks> that was bought a few years ago
[15:33:24] <skunkworks> https://www.youtube.com/watch?v=R9i4DbwZrKI
[15:35:33] <anarchos> http://www.ebay.com/itm/CNC-Digitizing-Probe-NEW-High-Accuracy-Barrel-Design-for-stepper-motor-machines-/291161285932?pt=LH_DefaultDomain_0&hash=item43ca90a52c
[15:51:05] <tjtr33> skunkworks, that looks so Buck Rogers
[15:51:34] <skunkworks> heh
[15:58:34] <tjtr33> http://preview.turbosquid.com/Preview/2014/05/20__08_45_13/raygun_sig_1200.jpg039777a7-0405-4598-b2a0-4f3f70e5c2efOriginal.jpg
[15:59:39] <skunkworks> love how it has an analog meter on it..
[16:18:25] <Deejay> gn8
[19:57:11] <Tom_itx> archivist does that tester measure shore hardness?
[21:10:44] <pfred1> does anyone have the md5sum for the Wheezy binary.hybrid.iso file?
[21:16:51] <pcw_home> 0xbadbadbadbadbadbadbadbadbadbadbadbadcafe
[21:19:20] <pcw_home> dont they list it on the download page?
[21:19:43] <pfred1> not that I saw there is a sum for the ubuntu version
[21:20:01] * pfred1 got 1d0025a8c1a61fbf32b99ab5797d95e3 binary.hybrid.iso
[21:20:04] <pcw_home> one I have from 10 days ago is
[21:20:05] <pcw_home> 0x1d0025a8c1a61fbf32b99ab5797d95e3
[21:20:15] <pfred1> looks good!
[21:20:36] <pfred1> sweet thanks saved me a plastic tree over here maybe
[21:20:48] <pcw_home> I could not get it to boot from usb though
[21:21:04] <pfred1> yeah no the PC Im putting it on doesn't boot off flash anyways
[21:21:10] <pfred1> got to burn it
[21:21:39] <pfred1> which is weird because i have two of them and one does boot off flash I guess the bios on the other one is older or something
[21:22:02] <pcw_home> I'm not sure that image will boot from flash
[21:22:21] <pcw_home> (tried 3 machines, no dice)
[21:23:25] <pcw_home> I could have munged the image somehow, I just used the dd example on the wiki page
[21:23:31] <pfred1> the fire is lit over here it is getting burnt
[21:23:42] <pcw_home> Tell me if the DVD boots
[21:23:52] <pfred1> will do
[21:24:25] <pfred1> I'm burning it with K3b
[21:26:21] <pfred1> heh I didn't know that K3b blew revelry when it finished
[21:31:03] <pfred1> I have it installing
[21:48:49] <pfred1> I must have screwed something up when I installed I do not see any Linuxcnc stuff on the desktop
[21:49:12] <pfred1> other than that it runs nice though :)
[21:54:23] <pfred1> I have axis on the desktop now
[22:18:48] <pcw_home> well may have to find one of those shiny round things with a hole in the middle to try wheezy
[22:19:01] <pfred1> yeah it works here
[22:19:16] <pfred1> I just ran stepconf
[22:19:36] <pfred1> that machine is under 12,000ns
[22:19:57] <pfred1> for a while it was holding under 11,00 but when I shut down glsgears there was a bit of a spike
[22:20:04] <pfred1> glxgears even
[22:21:45] <pfred1> I built my own custom Wheezy system a while ago but that machine developed a problem with its on board graphics chip
[22:21:57] <pfred1> frigging BGA popped up on me
[22:22:38] <pfred1> if I push it back down it works again but I feel it is just kind of sketchy now
[22:22:47] <pcw_home> popped off the board?
[22:23:02] <pfred1> yeah I guess I mean it didn't fall off but there is definitely a problem going on there
[22:23:26] <pfred1> gotta love lead free solder I guess
[22:23:44] <Jymmm> ewwwwwwwwwwwwwwwwwwwww
[22:24:29] <pcw_home> when we first changed to RoHS we hard a number of boards that if you twisted the PCBs a bit the BGAs would fall off
[22:24:31] <pfred1> it is a shame because that machine ran really well
[22:25:04] <pfred1> yeah something happened to it this winter in the cold
[22:25:10] <pcw_home> (before the assy houses got the process down)
[22:27:34] <pcw_home> Not seen a soldering problem for years now though lead free solder is a PITA if you have to hand solder
[22:28:18] <pfred1> that box is from 2007
[22:28:38] <pcw_home> yeah thats the transition time
[22:28:59] <pfred1> yup they didn't quite have it down then yet
[22:29:44] <pcw_home> Needed PCB material changes also
[22:30:12] <pcw_home> (for the higher soldering temperature)
[22:30:20] <pfred1> meh I only paid $5 for it but I lost the setup too
[22:30:55] <Jymmm> Is anyone aware of SS screws that are intended to "self tap" but NOT with a pointed end?
[22:31:05] <pfred1> I was thinking about trying to rig some kind of a clamp to hold teh chip down
[22:31:19] <Tom_itx> Jymmm if anybody would it would be fastenal
[22:31:33] <Jymmm> Tom_itx: oh gawd no, I hate that place.
[22:31:34] <pcw_home> rare earth magnets
[22:32:03] <Jymmm> Tom_itx: They primarily deal with constraction hardware, not fine thread stuff (around here)
[22:32:15] <pcw_home> (if the BGA has no heatsink)
[22:32:38] <Jymmm> Tom_itx: But I don't even know the NAME of them
[22:32:44] <pfred1> it might I can't even remember now I just pushed it once
[22:35:18] <Tom_itx> there are ones with a drill on the end or a slit on the end for self tapping
[22:35:37] <Tom_itx> http://www.fordfasteners.com/
[22:37:12] <pfred1> I wonder if it is safe to update that system or not?
[22:37:16] <Jymmm> Tom_itx: Yeah, those are NOT the ones I'm talking about, but ty
[22:37:39] <Tom_itx> not sure about fine threaded ones
[22:40:23] <Tom_itx> Jymmm, like some electrical boxes use?
[22:46:21] <pfred1> Jymmm we used some nice self drilling/self tapping SS screws working on a car wash once
[22:46:39] <pfred1> they even had sealing washer
[22:47:08] <pfred1> I still got a bunch
