[02:07:06] <Deejay> moinsen
[02:48:31] <Jymmm> ug
[02:52:32] <Deejay> hi jymmm
[03:02:57] <Jymmm> Deejay You normally work on Saturdays?
[03:03:33] <Deejay> i work all the time... like slaves do ;)
[03:03:47] <Jymmm> Deejay: =)
[05:06:01] <Jymmm> YAY for cotter pins!!!
[05:13:16] <archivist> cotter pin != split pin
[05:13:51] <archivist> real cotter http://en.wikipedia.org/wiki/Cotter_%28pin%29
[05:21:15] <Jymmm> I still have NFC what a Brit cotter pin is, and yes I did read the link
[05:21:39] <archivist> that link has a picture
[05:22:00] <Jymmm> Yes, I saw the pics too, still no clue
[05:22:09] <archivist> a split pin should not be called a cotter pin
[05:23:06] <Jymmm> Yes, I understand you wee doign the whole Brit thing (colour and all that), I choose to ignore that aspect, just trying to understand the object you linked to.
[05:24:23] <archivist> it was used on bicycle cranks, is a terrible device
[05:25:48] <Jymmm> Maybe that's why I didn't understand it; the design seemed "off"
[05:26:10] <archivist> http://bikebooboos.com/drivetrain/crank-loosefalls-off/ see lower on the page
[05:27:33] <Jymmm> Intended to just "tension" the two piece together to remove slop?
[05:31:02] <archivist> the taper should be tight, but hey were often too soft so came loose
[05:31:39] <Jymmm> Funny how we've come so far even with bicycles. I heard someone comment "Why your back doesn't have brakes, that's danergous" because they didn't see HAND brakes on the bicycle =)
[05:31:57] <Jymmm> s/back/bike/
[05:32:29] <Jymmm> that someone was a 20yo btw =)
[05:34:21] <Jymmm> Another piece to add to the "Never knew it existed" pile... "Records, 8 track tapes, FDD's" and now peddle backward bicycle brakes =)
[05:35:44] <archivist> peddle backwards was always a dumb idea
[05:36:01] <archivist> some used that as a gear change mechanism
[05:36:27] <Jymmm> never knew about the gear change
[05:36:49] <TekniQue> all of my old bikes had the brakes activated that way
[05:37:05] <TekniQue> you'd pedal backwards to engage the brake shoes
[05:37:15] <TekniQue> drum brakes of course
[05:38:15] <archivist> you cannot be peddling backwards at the time of putting feet on the floor
[05:38:44] <Jymmm> it only took one foot to engage the brake.
[05:39:41] <Jymmm> ride real fast, engage brake, do a 180 =)
[05:40:14] <TekniQue> yeah and of course only rear brakes
[05:41:31] <TekniQue> the current generation hipsters prefer bikes with no brakes whatsoever
[05:41:41] <Jymmm> lol
[05:41:45] <TekniQue> and no freewheeling clutch either
[05:41:54] <TekniQue> "fixie bikes"
[05:42:01] <TekniQue> morons
[06:08:23] <Loetmichel> *bah* i HATE orur router... which tends to fill its ram to the brim over time, so it needs a reset every other day.... provider-issuded Telekom Speedport W700V... if i wasnt so scrooge-y i would have bought a decent fritzbox some years ago... ;-)
[08:11:10] <seltecc> Hi, my machine is doing a level shift....meaning after vertical move it comes down deeeper and sometimes higher...donno where to start to try fixing it....?!
[08:18:07] <CaptHindsight> seltecc: you might try posting if it was working fine and it just started acting up or if it's always done this, what type of machine it is, the type of motors, etc etc
[08:26:09] <seltecc> captHindsight: thanks for reply. I come back to you if its ok when I have the proper informations ...
[08:46:09] <wtcnc> I've just downloaded binary.hybrid.iso. It's md5sum doesn't match the one given at linuxcnc.org (1d0025...), but it seems to boot fine in qemu. Is it possible that the one given at the homepage is wrong?
[08:51:05] <archivist> you url does not match the url that the md5 refers to
[08:59:47] <wtcnc> Well, the download page of linuxcnc says: 1. Download the ISO (points to http://www.linuxcnc.org/binary.hybrid.iso, wehere I got it from), 2. Burn ISO, 3. Check md5sum 1d0025... I did this and they don't match. Of course, I checked the md5sum before burning. Don't know why the instructions have it the other way round.
[09:01:18] <archivist> there are some inconsistencies with the site and languages
[09:02:30] <archivist> I did not see what you were seeing so ignore my reply, the md5 should match
[09:03:19] <archivist> I got thrown at the german page and the DVD is not there
[09:04:01] <wtcnc> Yes, the german page doesn't seem to have the newest version.
[09:08:09] <SpeedEvil> wtcnc: due to reasons, the ISO and the burned image may not be the same size
[09:08:21] <SpeedEvil> truncate the burned image to the size of the ISO, then hash
[09:11:19] <wtcnc> Well, I don't intend to burn it but rather use an USB stick.
[09:30:39] <XXCoder> wtcnc: it takes only one bit error to get completely differemnt hash
[09:30:57] <XXCoder> that's why we invented hash for
[09:32:47] <pcw_home> I get b515c872335336ccfc96471d66b687d8 with
[09:32:49] <pcw_home> md5sum binary.hybrid.iso
[09:50:48] <ssi> I don't know what I should try to accomplish today
[09:51:59] <Tom_itx> no laser cutting pls
[09:52:15] <ssi> boooo
[09:52:23] <Tom_itx> you know you'll never live that down
[09:52:31] <ssi> oh I'm sure
[09:52:40] <Tom_itx> hehe
[09:52:45] <ssi> you know I will have another laser? :)
[09:52:59] <Tom_itx> of course
[09:53:01] <Tom_itx> i would too
[09:53:50] <ssi> but I may do a 4x8' router first
[09:54:51] <archivist> I wont have a laser until I get some insurance
[09:54:59] <ssi> insurance is wise :)
[09:55:29] <ssi> honestly the laser isn't really that dangerous. The plywood sub-bed wasn't such a great idea, but hindsight and all
[09:55:30] <archivist> I cannot afford
[09:56:56] <ssi> I guess I may make a run to the house and try to retrieve my safe
[09:57:05] <ssi> and my trackbar, so I can start de-skidding some of these machines
[11:00:47] <archivist> toy for retrofit http://www.ebay.co.uk/itm/Leadwell-MCV610E-machining-centre-/151462564388
[11:09:47] <CaptHindsight> nice one
[11:16:15] <archivist> partial kit build your own solid cnc http://www.ebay.co.uk/itm/T-Slotted-Box-Table-for-Small-Radial-Drill-or-Large-Milling-Machine-/291286065466
[11:54:01] <marmite> hey internet i found this little thing in a junk sale
[11:54:02] <marmite> https://pbs.twimg.com/media/B176FB5IEAA7QFO.jpg
[11:54:06] <marmite> anyone know what the hell it is :D
[11:54:17] <marmite> both pins go difrent ways
[11:54:22] <marmite> and its bassicly a counter
[11:55:17] <archivist> you have two adapters, use one at a time
[11:57:24] <archivist> place in dimple in the end of a shaft and time for one minute
[11:58:26] <Tom_itx> i wonder if it measures thread pitch
[11:58:47] <Tom_itx> don't really know...
[11:58:50] <marmite> that could be something
[11:58:52] <marmite> gonna try it
[11:59:32] <marmite> nah dont really work
[11:59:58] <Tom_itx> not a rockwell hardness tester...
[12:00:17] <archivist> you see similar pointers/adapters with http://www.ebay.co.uk/itm/VENTURE-REV-COUNTER-TACHOMETER-/381040220721
[12:01:04] <pcw_home> manual tachometer...
[12:01:18] <archivist> they are low speed things usually, you need non contact optical for high speed
[12:02:26] <pcw_home> A number of those Leadwell mills have been retrofitted with LInuxcnc
[12:03:15] <archivist> some of the mechanical tachometers had the timer built in (Hasler)
[12:04:02] <marmite> ohh
[12:04:05] <marmite> coul.d be
[12:04:34] <pcw_home> That Leadwell looks pretty good (not a million dings in the table)
[12:05:20] <pcw_home> not outside in the rain...
[12:05:24] <marmite> ah this is only a counter, so it dont reeset or anything
[12:05:50] <marmite> could allways do the math
[12:05:51] <archivist> the right had side does the reset
[12:05:55] <archivist> hand
[12:05:57] <marmite> x amount numbers per min
[12:06:35] <archivist> I expect the knurled knob to reset to 0
[12:06:37] <marmite> the black dial on the end rools the dials from 0000 to 1111 then 2222 and so on
[12:06:40] <marmite> nopp
[12:06:52] <marmite> both the pins rotate
[12:07:00] <archivist> 0000 then you stop!
[12:07:08] <marmite> one clockwise the other anti clockwise
[12:07:16] <archivist> use one
[12:07:34] <pcw_home> (the one that counts up)
[12:07:42] <archivist> pull off the other adapter
[12:08:00] <marmite> yes done
[12:08:35] <marmite> hmm iguess it could be that
[12:08:51] <archivist> I have an old one of http://www.technicalshipsupplies.com/products/TACHOMETER-HAND-HASLER-TYPE-HL.html
[12:08:57] <marmite> hmm wounder what the pointed one could be used for then :D'
[12:09:11] <marmite> ah fancy
[12:09:22] <archivist> that grips a centre in the end of a shaft
[12:09:33] <marmite> ahh
[12:10:00] <archivist> others have a rubber cone instead
[12:10:17] <marmite> ah i see
[12:10:28] <marmite> one cool item then :D
[12:11:33] <archivist> useful for old lathes and stationary engines
[12:11:56] <marmite> indeed
[12:15:37] <marmite> cool item to have :D
[12:18:52] <pcw_home> hows this for embedded processing:
[12:18:53] <pcw_home> http://upload.wikimedia.org/wikipedia/commons/c/c9/NSA_FIREWALK.jpg
[12:21:59] <archivist> not sure it is believable
[12:22:18] <pcw_home> Not sure either
[12:22:25] <marmite> probebly aint
[12:22:33] <archivist> power source for that?
[12:22:46] <pcw_home> USB
[12:23:05] <zeeshan|2> someone watched too much hackers 2
[12:23:06] <zeeshan|2> :]

[12:23:56] <zeeshan|2> lol
[12:24:18] <pcw_home> If you look at howlermonkey it looks real
[12:24:23] <zeeshan|2> i was looking at going into micro immunology or dentist
[12:24:33] <zeeshan|2> but after those movies i knew i wanted to get my hands dirty :D
[12:24:51] <pcw_home> and no more advanced than a cell phone
[12:25:01] <marmite> :P
[12:25:19] <marmite> i ended upp with working with fiber optics insteed
[12:27:24] <marmite> http://www.blocket.se/uppsala/Fras_sajo_varnamo_57073868.htm?ca=10&w=3 one sexy machine
[12:27:34] <marmite> 4725 usd
[12:27:56] <marmite> hahahahaha its my friend that sells it :DD just noticed
[12:30:34] <sliptonic> are DEFAULT/MAX_ANGULAR_VELOCITY used by gmoccapy? Can't figure out how to make A axis jog faster than a crawl.
[12:57:19] <awallin> marmite: about 500 usd/eur would be ok for that boat-anchor ;P
[16:08:28] <Deejay> gn8
[18:07:40] <ssi> quiet night
[18:17:17] <jdh> its saturday!
[18:17:25] <ssi> is that supposed to be an excuse?!
[18:19:58] <jdh> I spent the day diving.
[18:20:06] <ssi> I spent the day driving :(
[18:21:00] <jdh> driving is ok if you are driving to diving.
[18:21:46] <ssi> I wish
[18:22:02] <ssi> I was driving to the dealership to sit in a waiting room for two and a half hours waiting on a service, with a dead cellphone and nothing to do
[18:22:09] <ssi> then driving to my burned out house to move a safe
[18:22:12] <ssi> then driving back down here
[18:30:27] <jdh> no computers in the waiting room?
[18:45:53] <Tom_itx> should have taken your charge plug like all the ppl at the airport sitting around the plugs
[18:47:34] <pcw_home> they new campfire
[19:08:41] <Jymmm> thats sad
[23:50:16] <Computer_Barf> I got a grizzley G0704 today
[23:52:37] <Computer_Barf> in the box of extra stuff that the guy that sold it to me came with, there is an arbor , and a drill chuck. They are separate but im not for certain that they go together. The end of the arbor is tapered and fits into the back of the drill chuck, though it doesn't appear to go all the way in.
