12:08 AM Cromaglious_ is now known as Crom
12:10 AM Wolf_: nice lol
12:12 AM Crom: he had just built a 486SX-25, and I had to 386sx-40's for programming on the Super Nintendo Entertainment System We were working of Gordo 106 a side scroll game... and also working with Atari on the new Jaguar Tank Battle
12:15 AM Crom: Those Jaguar developement systems were really easy to let the magic smoke out of
12:15 AM Crom: I think we went through 5 or 6 of them... 3 we had to open windows to let it air out
12:15 AM Wolf_: lol
12:15 AM Crom: The GPU ran really hot and you could fry it pretty easy
12:17 AM Crom: I was working at Providein the credit card shark around then
12:17 AM Wolf_: admin for a novell 3.1 file server with a giant 12gb mirrored array in it.. all 20 drives worth
12:19 AM Wolf_: and here I am looking at things that look like toasters on newegg that hold so much more lol
12:19 AM Crom: I was the in the Computer room tech.. watching the 2TB Optical library, big ass Xerox printer, pyramid 16 pentium 66 'mini' frame, some HPUX boxes as well...
12:20 AM Wolf_: I need a new NAS
12:20 AM Crom: then I went to SNC Long Distance... Perl Weenie... data integrity for interm billing system..
12:21 AM Wolf_: and I fucked up earlier, there was a DS1815+ on newegg open box for $640 and I didn’t hit the order button
12:21 AM Crom: hehe that's a pine a64+
12:22 AM Crom: s/snc/SBC/
12:23 AM Crom: southwesten Bell
12:24 AM Crom: welp... nite nite all... Have to get up early.. first Riverside, then Morro Bay, then Santa Cruz tomorrow
01:47 AM MacGalempsy: slow night drilling
01:48 AM MacGalempsy: Wolf_ what are you up to?
01:48 AM Wolf_: not much at all right now
01:49 AM Wolf_: trying to figure out what NAS to blow some $$$ on
01:50 AM yasnak: gotta love when someone bangs the uppper guide on the edm and doesn't say anything. trying to thread the wire and its on a 5 degree angle. thought i was crazy
02:18 AM archivist: just shove a drive in a pc and connect to the pc
02:21 AM archivist: to avoid the arduino used in a nas box :)
02:23 AM Wolf_: lol
02:25 AM archivist: last time I used one was not a good experience
02:25 AM Wolf_: the one I have now works fine, just ran out of room on it
02:27 AM archivist: replace the disk?
02:27 AM Wolf_: I could, just a raid1 box tho
03:16 AM Deejay: moin
05:11 AM jthornton: morning
05:26 AM enleth: Wolf_: HP MicroServer boxes are decent NAS bases
05:27 AM enleth: Gen8 are very cheap, the newer versions less so but still affordable
06:39 AM XXCoder: boom
06:43 AM jthornton: morning
06:43 AM XXCoder: hey jt
06:43 AM XXCoder: today wasnt nice work day
06:44 AM jthornton: yuck
06:44 AM XXCoder: there was minor power issue
06:44 AM XXCoder: a61 stopped right away which is good
06:44 AM XXCoder: whats not so good is that one kinda expensive part was in middle of being tapped
06:44 AM XXCoder: so I couldnt restart it, nobody knows enough to fix that
06:45 AM jthornton: that is a mess I bet
06:45 AM XXCoder: yeah poor day shift
06:45 AM XXCoder: hes only one that can do that stuff.
06:45 AM XXCoder: we used to have 3, but one quit due to no pay rises for years, and other was fired
06:46 AM XXCoder: I know more than average worker there on a61 but I cant do setup and such. if that worker quit or was fired, we are scrwed on a61.
06:47 AM XXCoder: oh and been running ye olde fadal 88 at same time, as not enough workers to run that!
06:47 AM XXCoder: so much walking.
06:48 AM jthornton: walking is good for you :)
06:48 AM XXCoder: yea though tomorrow wont be fun
06:48 AM XXCoder: fadal I just finished setup on part that takes 30 seconds to run
06:48 AM XXCoder: meaning either I dont run fadal or I run it alone
06:49 AM XXCoder: well maybe if I just go to a61 each hour and catch up or something.
06:50 AM XXCoder: ordered some coffiest
06:52 AM jthornton: yea most of the the time I spend 15 minutes or so in CAM 10 minutes setup 30 seconds machining 5 minutes putting cutting tools back for each part lol
06:54 AM XXCoder: heh
06:55 AM XXCoder: one machine at work it's almost faster if it was manual change
06:55 AM XXCoder: its arm takes almost minute to move to spindle
06:55 AM XXCoder: tool change 30 seconds to minute (depending rotate distance)
06:55 AM XXCoder: then minute back
06:55 AM Jymmm: XXCoder: machine you one of these https://0075397ca1480a6422a6-373ec2a9a8c1bd0dc32a6d880ae07ded.ssl.cf1.rackcdn.com/wp-content/uploads/2011/11/e100_prod_rd-400x470.jpg
06:55 AM XXCoder: its postive is that its huggge
06:56 AM XXCoder: lol why not
06:56 AM jthornton: yea my BP Discovery 308 has a very slow tool change time
06:56 AM Jymmm: XXCoder: it's an electric scooter
06:56 AM XXCoder: I know :P
06:57 AM XXCoder: olvious battery pack is olvious
06:57 AM Jymmm: XXCoder: then you dont have so much walking to do
06:58 AM Jymmm: We had a manual one at the datacenter I worked at.
07:00 AM XXCoder: boeing has bicycles
07:54 AM jthornton: https://www.youtube.com/watch?v=ZusEXRiAYMw&index=7&list=PLAXE_Je4H9MFWvUKpHWs9ngDbUd_1Ai2x
07:55 AM XXCoder: big batter
07:55 AM XXCoder: okay reached my limit at 25 seconds
07:59 AM jthornton: https://www.youtube.com/watch?v=dTC3f3DIYJs
08:00 AM XXCoder: unwatchable for now, unfortunately
08:00 AM XXCoder: while im not dizzy anymore now, still quite sensive
08:03 AM gregcnc: jymmm what were you doing with propylene glycol yesterday?
08:09 AM archivist: someone else was asking about spindle cooling
08:13 AM gregcnc: ok I thought it was unrelated, used in many applications
08:16 AM XXCoder: https://cabristor.blogspot.se/2015/02/drv8825-missing-steps.html?m=1 interesting read
08:16 AM XXCoder: though dont understand sections of it
08:23 AM gregcnc: seems like a design problem with the driver
08:24 AM XXCoder: seems so. my 3d printer is a4864 so no issues
08:24 AM XXCoder: I ordered another one so I can drive another extruder
08:32 AM JT-Shop: going for dual extruders?
08:33 AM XXCoder: yeah I have extra stepper that I fixed
08:33 AM XXCoder: and ramps has extra slot so why not
08:36 AM JT-Shop: cool
08:37 AM XXCoder: dual color
08:37 AM JT-Shop: nice can't wait to see that
08:38 AM XXCoder: 3d printer is low priority
08:38 AM XXCoder: I got those since same seller as well an grab em
08:55 AM {HD}: How does china sell things for 40 cents free shipping. That is the cost of a stamp here in the US.
08:56 AM archivist: because bulk agreements
08:57 AM SpeedEvil: Also postal subsidies intended to benefit poor peasants.
08:58 AM archivist: and container shipping is damned cheap
08:59 AM archivist: which upsets local manufacture
08:59 AM {HD}: Still amazes me. No wonder radio shack went bankrupt. You can buy everything on ebay for almost nothing.
09:06 AM enleth: OK, so I'm looking for someone in the US (preferably California) willing to hold onto a servo drive I'll be selling off on ebay, to get it shipped when I find a buyer
09:07 AM enleth: I've got this Bosch Z15-1A drive that's close to worthless in Europe but a couple sell every quarter in the US
09:07 AM enleth: but no one is going to buy it and wait for international shipping - people only buy it when they need to replace a failed one ASAP
09:08 AM archivist: just took 20 days US to UK
09:09 AM enleth: preferably California because a friend of mine is flying there in a couple days and there's a chance he'll be able to take that servo drive with him to mail it to someone local
09:11 AM enleth: (although I have really no idea if USPS/whatever parcel prices are significantly different between same state, neighboring state or the other side of the US - if not, then it doesn't matter and I'm just looking for someone in the US in general)
09:12 AM roycroft: usps rates are generally flat rate
09:12 AM roycroft: ups/fedex are zoned
09:12 AM {HD}: ^
09:12 AM {HD}: beat me too it
09:13 AM enleth: oh well, then I'm just looking for someone in the US willing to help me with that
09:14 AM {HD}: enleth: I would but I am unreliable due to the frequency that I travel.
09:14 AM enleth: with some reasonable fee for the trouble
09:14 AM enleth: {HD}: fair enough
09:16 AM zhivko: Dear all... I am trying to figure out how to make gcode so that thc.comp will not hurry too soon to material when piercing
09:17 AM zhivko: looking at: https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/components/thc.comp it seems that it tries to do compensation according to: if(torch_on && arc_ok && vel_status){ // allow correction
09:20 AM zhivko: I think having: G04 P3 (pause for 3 seconds) would make vel_status == 0 so it should stop thc.comp operating? Any opinions on that maybe?
09:27 AM {HD}: Gotta hook up my micro switches to my parallel port breakout board today...Should I wire in a debounce RC or just wait and see if it needs it?
09:45 AM _nexxus__ is now known as _nexxus_
09:54 AM Simonious: Guys got any experience with logging data to a USB stick? I want the stick to last as long as possible before it fails. I've been messing around with nilfs2, but it's giving me a little trouble. I could use a recommendation on a filesystem.
10:06 AM {HD}: Simonious: need more information
10:07 AM IchGucksLive: hi
10:07 AM Simonious: {HD}: I've got plenty more information :) I understand the USB sticks will fail, I just want them to last as long as they reasonably can before they do, so I expect an FS that handles load leveling is a good choice. Nilfs2 is, but it isn't behaving well for me, so I'm looking for other options.
10:07 AM IchGucksLive: zhivko: still on
10:07 AM zhivko: yes
10:08 AM zhivko: :)
10:08 AM IchGucksLive: i own 4 plasmas on THCUD
10:08 AM IchGucksLive: im in Germany
10:08 AM zhivko: IchGucksLive: do you us thc.comp ?
10:08 AM zhivko: IchGucksLive: do you use thc.comp ?
10:08 AM IchGucksLive: First to your question i need to know what THC you work on
10:09 AM IchGucksLive: i do use THCUD
10:09 AM IchGucksLive: as i got Eagle thc on the mashine
10:09 AM zhivko: I use: https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/components/thc.comp
10:09 AM IchGucksLive: http://linuxcnc.org/docs/html/man/man9/thcud.9.html
10:09 AM zhivko: I do not have thc as device - but use thc.comp... it adjust Z accordingly on the fly
10:10 AM IchGucksLive: zhivko: what hardware do you got for thc
10:10 AM zhivko: yes that's the one.
10:10 AM zhivko: I have no additional HW... just 3 axis and Z axis is imfluenced by thc.comp
10:10 AM IchGucksLive: so why in all do you use thc
10:10 AM zhivko: As you may see from code
10:11 AM IchGucksLive: use 2 buttons that interupt the Z
10:11 AM zhivko: because I want to assure I have fixed distance of plasma to material
10:11 AM IchGucksLive: go for THCUD is better for you
10:11 AM zhivko: what is THCUD ?
10:11 AM IchGucksLive: the same but on poinstate not on Voltige
10:12 AM IchGucksLive: Pinstate
10:12 AM IchGucksLive: it becomes signal pull up pull down from a THC device
10:12 AM IchGucksLive: like
10:12 AM zhivko: oh - I dont want to have additional device
10:12 AM zhivko: It complicates things
10:13 AM IchGucksLive: http://eagleplasma.com/torch-height-controls.html
10:13 AM zhivko: I have THCAD that converts plasma voltage to freqvency signal
10:13 AM IchGucksLive: you can get the signal from where ever you want
10:13 AM IchGucksLive: just up and down
10:13 AM IchGucksLive: and the componend does the rest
10:14 AM IchGucksLive: on The THC Eagle you only need 2 Pins to run a correct THC maschine
10:14 AM zhivko: how do you turn it on - I mean how it know when piercing is over ?
10:14 AM IchGucksLive: it has a internal delay
10:15 AM IchGucksLive: and only gives signal if torch is on
10:15 AM IchGucksLive: with a 3rd pin the mashine knows also the tourch has firerd
10:15 AM {HD}: Simonious: Hum, well all my usb drives are fat so, I am not taking advantage of any wear leveling filesystem. You have peaked my interest.
10:15 AM IchGucksLive: so you can move on or stop if somthing is wrong
10:16 AM Simonious: {HD}: I've murdered these drives in the past and will in the future, I just want them to last as long as possible under data logging conditions.
10:17 AM zhivko: how do you control that internal delay
10:17 AM IchGucksLive: it is in the setup
10:17 AM zhivko: You see if you trust everything is in this additional box - it means you need to teach operater how to raise up dela for thicker material.
10:17 AM zhivko: Better is if sw can do that automatically for you
10:17 AM IchGucksLive: https://www.youtube.com/watch?v=560knsCBqNk
10:18 AM zhivko: as soon when you have additional box - it seems you cannot raise delay from w
10:18 AM zhivko: sw
10:18 AM IchGucksLive: https://www.youtube.com/watch?v=JpYQJwFus0c
10:18 AM IchGucksLive: the last video gives you a idee on how it workes
10:19 AM IchGucksLive: look at the 2 led obove the Volt number
10:19 AM IchGucksLive: you can set the workvoltige
10:19 AM IchGucksLive: the uper and lower to start thc
10:20 AM IchGucksLive: the pirce delay
10:20 AM IchGucksLive: zhivko: you can do this also by Mcode in the Gcode
10:22 AM zhivko: you mean set delay?
10:22 AM IchGucksLive: halcmd setp thcud.enable True = M160
10:22 AM IchGucksLive: halcmd setp thcud.enable False = M161
10:22 AM zhivko: you used thc.comp before and it was not tnough thatn you bough proma ?
10:22 AM IchGucksLive: so THC is controled by a Mcode
10:22 AM IchGucksLive: after the pirce
10:23 AM IchGucksLive: M3
10:23 AM IchGucksLive: G04 P1
10:23 AM IchGucksLive: Z1.5
10:23 AM zhivko: possibly but I have thc.comp and not thcud
10:23 AM IchGucksLive: M160
10:23 AM zhivko: so I need solution for thc.comp
10:23 AM IchGucksLive: zhivko: write a ud beond thc and you are in
10:24 AM zhivko: ud?
10:24 AM IchGucksLive: it is comming with liinuxcnc
10:24 AM IchGucksLive: no install
10:24 AM IchGucksLive: loadrt thcud
10:24 AM IchGucksLive: instad of loadrt thc
10:24 AM IchGucksLive: where is your problem
10:24 AM zhivko: but then I need proma device - no?
10:24 AM IchGucksLive: no
10:25 AM IchGucksLive: what hardware do you got to detect the Torch voltige
10:25 AM zhivko: so my initial problem was - I am using thc.comp
10:25 AM zhivko: and now I see it moves too quickly to material...
10:25 AM zhivko: maybe this is because I have dela 0.4 second - and I use relay...
10:26 AM zhivko: to start plasma... and relay is maybe too slow...
10:26 AM IchGucksLive: do it by User Mcode
10:26 AM zhivko: I use: G04 P0.4
10:26 AM IchGucksLive: with ypour THC.comp
10:26 AM zhivko: for pause
10:26 AM IchGucksLive: that m akes your torch time lower
10:27 AM IchGucksLive: as you burn without movement
10:27 AM zhivko: yes I think pause 0.4 seconds should be lengthen by the relay start
10:28 AM zhivko: I am not sure what time my relay needs to fire
10:28 AM zhivko: from the time it gets signal...
10:29 AM IchGucksLive: here is a part of my G-code
10:29 AM IchGucksLive: G00 Z25.000
10:29 AM IchGucksLive: X6.500 Y6.500
10:29 AM IchGucksLive: Z3.000
10:29 AM IchGucksLive: G4 P2
10:29 AM IchGucksLive: M03
10:29 AM IchGucksLive: G01 Z1.5 F500
10:29 AM IchGucksLive: M160
10:29 AM IchGucksLive: G01 F100
10:29 AM IchGucksLive: G02 X6.500 Y9.250 Z1.500 I0.000 J1.375 F600.0
10:29 AM IchGucksLive: X6.500 Y9.250 I0.000 J-2.750
10:30 AM IchGucksLive: X7.780 Y7.970 I0.000 J-1.280
10:30 AM IchGucksLive: m161
10:30 AM IchGucksLive: M05
10:30 AM IchGucksLive: G00 Z25.000
10:30 AM IchGucksLive: M160 firers the THC
10:30 AM IchGucksLive: M161 Disables the THC
10:30 AM IchGucksLive: Software no hardware
10:30 AM IchGucksLive: it just interrupt the Enable
10:31 AM IchGucksLive: so the signals in cand be processed
10:31 AM IchGucksLive: postprocessor is sheetcam
10:32 AM IchGucksLive: zhivko: this are USER Mcodes
10:32 AM zhivko: How can I find in my linuxcnc that M160 enables thc or not?
10:32 AM IchGucksLive: you need to ad them by yourself
10:32 AM zhivko: Where is this M160 defined ?
10:32 AM IchGucksLive: in nc_files
10:33 AM IchGucksLive: it is a Homemade Mcode just a NGC file
10:33 AM zhivko: can you pastebin such nc file ?
10:33 AM zhivko: So I would see how M160 is defined...
10:33 AM zhivko: or paste link to any of such file
10:33 AM IchGucksLive: #!/bin/bash
10:33 AM IchGucksLive: # file to activate THC - M161
10:33 AM IchGucksLive: halcmd setp thcud.enable False
10:33 AM IchGucksLive: exit 0
10:33 AM IchGucksLive: safe thei as M161
10:34 AM IchGucksLive: no ending in the nc_files
10:34 AM IchGucksLive: and di a Right klick on it make executable
10:34 AM IchGucksLive: M160 is the oposit
10:34 AM IchGucksLive: as You see it interacts on the THCUD component
10:35 AM IchGucksLive: here is the comp list
10:35 AM IchGucksLive: http://linuxcnc.org/docs/html/man/man9/
10:36 AM IchGucksLive: thc.enable bit in
10:36 AM IchGucksLive: or
10:36 AM IchGucksLive: thc.arc-ok bit in
10:36 AM IchGucksLive: im off
10:36 AM IchGucksLive: workend here
10:37 AM IchGucksLive: bye till 7pm Berlin time
11:45 AM Jymmm: gregcnc: I only use PG for vaping, more so VG than PG.
11:45 AM Jymmm: gregcnc: CaptHindsight says he uses it for soemthing else, but nbody knows what that is
11:46 AM gregcnc: did you tell me about LPS Aquacut?
11:47 AM gregcnc: lol we know what it is
11:48 AM Jymmm: gregcnc: smells like cinamon, yeah I did http://www.lpslabs.com/product-details/633
11:48 AM gregcnc: it's PG based
11:49 AM Jymmm: ah
12:02 PM gregcnc: makes me wonder how effective rv antifreeze is for coolant in a machine, other than it likely lacks rust inhibitors https://www.lubecorp.com/greencut-cutting-fluid/
12:20 PM {HD}: what do you think of my control board layout? http://imgur.com/a/4MgQ7
12:20 PM {HD}: My concern is maybe the breakout board is too close to the VFD? or that maybe running wires from the driver to the bob between the PSUs will effect the signal....
12:21 PM {HD}: what do you guys think?
12:24 PM jdh: that's a lot of PS
12:26 PM archivist: I use one psu for all steppers
12:26 PM {HD}: I have not done load testing to see how much I really need but I am running nema 34s at 7amps each...
12:28 PM jdh: http://www.geckodrive.com/support/step-motor-basics/power-supply-basics.html
12:31 PM Simonious: I think I'm just going to go with EXT2...
12:31 PM {HD}: Simonious: Yea, ext2 no journaling
12:31 PM * Simonious nods
12:32 PM jdh: 2 10A would be sufficient.
12:32 PM {HD}: jdh: Looks like I should do some basic calcualtions
12:37 PM * Loetmichel_ just nodded away on the commute home... luckily i have a pretty good sound system in the car... yello"the race" and all dials on 11 and soon you have the gratis massage and are wide awake again. only sad the stock radio/satnav that came with the car cant keep up with the speakers. after 5 minutes the subs/lows start to fade out (amplifier chips overheating) :-(
12:39 PM Wolf_: need self driving car
12:39 PM Wolf_: and not self driving in to a tree or something ‘
12:43 PM Loetmichel_: didnt swerve off, just noticed that i havent seen the last 100m street or so
12:43 PM Loetmichel_: so i appplied countermeasures
12:43 PM Loetmichel_: it only had to last 10 min, i only have to drive 12km home
12:44 PM {HD}: Look at the screws I just pulled out of one of these PSUs. http://i.imgur.com/HKfswEo.jpg oh China…
12:45 PM archivist: I had one of the china psus explode from the vibration of a stepper on the bench
12:45 PM Loetmichel_: {HD}: i usually have one or two (of the right ones) in a box of 1000 from the screw dealer when i buy the cheap ones
12:45 PM Loetmichel_: its not china, that even happens in german manufacturers
12:45 PM SpeedEvil: archivist: Step without rhythm, so you don't attract the wyrm.
12:46 PM Loetmichel_: ... but then using those in a product IS typical chinese, grant you that ;)
12:46 PM {HD}: archivist: I am glad I opened these because there is a loose clamp in each.
12:47 PM archivist: you invalidated the worthless guarantee !
12:48 PM {HD}: There was no security sticker! They cannot prove anything.
12:54 PM {HD}: I am opening the other 2 just to make sure and they are all a little wonky.
12:59 PM {HD}: Why is my transformer covered in Schmutz? http://i.imgur.com/zLpEUTt.jpg
01:00 PM archivist: dirty process or too hot in the bake
01:01 PM {HD}: Well opening these things up gave me the 'anti warm and fuzzies'
01:04 PM enleth: is polyester "felt" OK for way wipers?
01:08 PM {HD}: enleth: I would not think so if you are using coolant/lube...
01:13 PM enleth: OK, I'm thinking an inner layer of felt and outer layer of hard rubber
01:13 PM enleth: as in, natural felt
01:17 PM {HD}: enleth: Sounds better but, I am no expert. I just know 'poly' things dont play nice with other poly things...
01:28 PM enleth: well, I found some 2mm natural felt and 1mm oil-resistant natural rubber in sheets, cheap, from one supplier
01:29 PM enleth: and some quick googling suggests that this is a good combo
01:30 PM enleth: possibly with some sheet brass bent at an angle on top of all that
01:30 PM enleth: to literally scrape over the ways
01:30 PM IchGucksLive: hi
01:36 PM {HD}: So, looking at these PSUs pretty much every threaded hole is stripped out.
01:37 PM {HD}: There is maybe 2 out of 6 fasteners on each that is doing anything.
01:37 PM jdh: more thab enough
01:38 PM IchGucksLive: hi zhivko
01:38 PM IchGucksLive: did it work
01:38 PM zhivko: hi
01:39 PM CaptHindsight: {HD}: worse are the cheap screw connectors they use that immediately strip when tightened on a wire
01:45 PM {HD}: CaptHindsight: That would be worse, I don't have any of those. I did have the chassis shorted to the +60v rail tho...
01:46 PM {HD}: jdh: Really enough? I was going to retap all of these...
01:46 PM jdh: that was a joke. sorry.
02:04 PM Wolf_: great, can’t remember who I was talking to about laser safety glasses, for 450nm blue diode 2.5w http://www.kenteklaserstore.com/kxl-5305-laser-safety-glasses-argon-ktp.aspx should help keep my eyeballs intact right?
02:05 PM Wolf_: and co2 I think?
02:06 PM {HD}: They look cool
02:07 PM {HD}: I want a hand help 'burning laser' for popping ballons and lighting matches...any sugesstions?
02:07 PM {HD}: help = held
02:07 PM Wolf_: yeah, that they do, not that I care what they look like as much
02:08 PM Wolf_: just don’t want to cook a retina out with the blue laser
02:10 PM Wolf_: many on aliexpress lol
02:10 PM andypugh: http://www.ebay.co.uk/itm/Quality-Protection-Safety-Laser-Glasses-Goggles-Eye-Protection-Laser-Goggles-/111879066898?hash=item1a0c831512:g:UikAAOSwLnlWnaBw Must be good, says “quality” right there in the title.
02:10 PM andypugh: At that price, buy two and _test_ them. (not with an eyeball)
02:10 PM Wolf_: http://i.imgur.com/4T5zBjC.jpg 2.5W http://i.imgur.com/2WblNO2.jpg thats unfocused and burning by hand
02:11 PM Wolf_: lol andypugh
02:11 PM Wolf_: ebay is chock full of cheap laser glasses
02:11 PM andypugh: Not actually joking. I would trust some that I have tested more than some that I paid a lot of moeny for and didn’t test.
02:11 PM {HD}: Wolf_: Cool scribbles!
02:12 PM {HD}: andypugh: What do you use for an eye analog?
02:12 PM Wolf_: put paper on the other side of the glasses
02:13 PM {HD}: are blue or green lasers burnier?
02:13 PM Wolf_: the Kentek seem legit
02:14 PM andypugh: I can sell you some for $255 if they would seem even more legit
02:14 PM Wolf_: I mean actually rated and not random marked china crap
02:15 PM Wolf_: http://www.ebay.com/itm/New-Kentek-KXL-5305-Laser-Safety-Glasses-for-Argon-and-KTP-/291865119563
02:15 PM andypugh: They are being a bit more specific about performance @ wavelength, I will grant you.
02:15 PM Wolf_: look at their front page lol
02:28 PM IchGucksLive: https://youtu.be/_8EcJnrXFAI can somone check if it is public i do not know why youtube since i passed the 1000 people per day line do only privat uploads
02:29 PM Wolf_: looks public
02:31 PM IchGucksLive: thanks
02:34 PM IchGucksLive: zhivko: https://youtu.be/_8EcJnrXFAI
02:34 PM IchGucksLive: video for your problem
02:34 PM IchGucksLive: im off Gn8
02:35 PM IchGucksLive: will be off tomorrow for trade show
02:35 PM Wolf_: anyways, back to the glasses I linked, the range is correct for co2 and the 450nm diode? even tho it says its for Argon/KTP
02:36 PM Wolf_: ^that was my actual question, not if they were any good or not lol
02:45 PM Cromaglious_: Morning
02:47 PM Cromaglious_: Looks like my jmc-motor.com 2nm drives might be ordered this week.
02:51 PM Cromaglious_: Once I get those installed and debugged, I can make some circuitboards for my limit switches/sensors.
03:04 PM Cromaglious_: Thinking about making a generic board able to handle, limits, homes alarms, estop, then also for either switches or sensors Power for snsors 5v, 12v, 24v, hook up for normally open sensor and normally closed..
03:07 PM Cromaglious_: 5v 3amp would be nice to drive sensors and the BOB. Hmm 2 pots for a variable voltage divider for PWM. Spot to mount a couple of Nanao's or attiny 85..
03:08 PM Cromaglious_: hiya Nick
03:12 PM selroc: hello, I was looking at pncconf and noticed that it lacks a XYZAB configuration template
03:12 PM Cromaglious_: probably true... 5 axis is kinda rare to be actually built
03:13 PM selroc: but the board has 5 axis
03:13 PM Cromaglious_: configure for a XYZA... when done go into the files .ini .hal and changed them
03:14 PM selroc: I am supposed to know how to change them ?
03:14 PM Cromaglious_: you'll have examples in the other 4 axises and joints
03:15 PM Cromaglious_: use a decent editor that'll split screen and that makes it easier
03:16 PM Cromaglious_: I tend to use joe in command line interface
03:17 PM Cromaglious_: since its the closest to wordstar and qedit in key mappings
03:18 PM selroc: I can have the best editor but fail miserably if I don't know how to change the files hmm
03:19 PM Cromaglious_: it's basically monkey see, monkey do...
03:20 PM Cromaglious_: look how axis0 joint 0 are setup, do the same for 1,2,3, then you should be able to make a axis and joint 4
03:21 PM selroc: thanks
03:27 PM Cromaglious_: de nada amigo
03:29 PM Cromaglious_: I found Jesus!
03:30 PM Cromaglious_: hows it going JesusAlos ?
03:53 PM DaViruz: andypugh: greetings from austia!
03:54 PM JesusAlos: Cromaglious_: Hi! what happend?
04:28 PM Cromaglious_: you walked in... so I said 'I found Jesus1'
04:28 PM Cromaglious_: s/1/!/
04:29 PM Cromaglious_: I lost Jesus!... Guess I'm a Budhist again...
04:48 PM Jymmm: Cromaglious_: one of those ancient long lost religions, like human
04:50 PM Cromaglious_: heh
04:53 PM Cromaglious_: looks like I'm getting JMC-motor.com integrated closed loop steppers
04:55 PM andypugh: Hi DaViruz
04:55 PM Cromaglious_: I need to find some side line gigs.... changing light switches or outlets... there's an easy $100 or so bucks
04:55 PM Cromaglious_: morning Andy
04:56 PM andypugh: DaViruz: Skiing?
04:59 PM andypugh: Mathematics puzzle. If a BT / CAT / ISO taper is 7/24 what angle do you set the compound slide to?
05:00 PM andypugh: (I have been doing it wrong for years, I think)
05:00 PM enleth: damn, the ORAC's X axis ball screw is a bit too crunchy for my liking, something must have gotten into the ball nuts
05:02 PM Cromaglious_: run of 24 deflection of 7?
05:02 PM andypugh: Yes
05:03 PM andypugh: enleth: It’s not _too_ horrible to take them all apart and put them back in. I won’t claim it’s _fun_ mind.
05:03 PM Cromaglious_: angle == atan2(7,24) * 180 / pi
05:03 PM Cromaglious_: in degrees
05:04 PM Cromaglious_: or 24,7
05:04 PM andypugh: 7/24 is diameter
05:04 PM enleth: andypugh: well, I did reload the Z axis nuts: http://imgur.com/a/5p2Ff (click "load more" at the bottom)
05:04 PM gregcnc: 8.297°
05:05 PM enleth: andypugh: the problem is that X ball screw is 8mm dia/2.5mm pitch, so the nuts are really tiny
05:05 PM andypugh: External ball return tubes makes it easier
05:05 PM enleth: andypugh: and the way they're mounted to the cross slide is, well, weird
05:06 PM andypugh: gregcnc: Is the right answer
05:06 PM andypugh: 8.130 degrees is the wrong answer, and that is what I have been using…
05:06 PM enleth: andypugh: those Z axis nuts in the gallery I linked were easy because they were bolted to the mounting block (or whatever is the proper term for that block between them)
05:07 PM gregcnc: how did you arrive there and did bluing not show it?
05:07 PM enleth: andypugh: the X axis is different - the nuts are threaded, and they screw into that block
05:07 PM enleth: which means I can't remove them one by one
05:07 PM enleth: and I can't reload them individually
05:07 PM Cromaglious_: DIN 2080, ISO, NT, NST, NMTB, CAT, BT, 7:24 (3.5:12) taper on diameter, 8°17′50″ half-angle, all use the same taper angle. As discussed here there are other considerations besides the taper angle.
05:08 PM andypugh: gregcnc: atan(7/24) … Oh, that looks like too much, so atan(7/24) / 2
05:08 PM andypugh: But it’s actually atan(7 / (24 * 2))
05:09 PM gregcnc: aha math fumbles
05:09 PM andypugh: It makes a 0.14mm difference at the small end of a BT30. Easy to miss if the big end fits..
05:10 PM enleth: https://hackerspace.pl/~enleth/IMG_20170322_223824.jpg - that's the screw and all. the nuts both have right hand threads that thread into the block. which means I can't just unscrew one of them loose
05:10 PM enleth: I think I have to rotate the screw out of them
05:10 PM enleth: then reload them while threading the screw back in
05:11 PM gregcnc: I suppose with light loads at bad taper might not show
05:11 PM malcom2073: Wow heh, not much to that ORAC without its benchtop case
05:12 PM gregcnc: just an Emco compact 8?
05:12 PM enleth: yep, just Emco 8
05:12 PM Cromaglious_: mcmaster just bought enco right?
05:13 PM gregcnc: MSC bought Enco not Emco
05:13 PM andypugh: enleth: A tube that fits round that plain section will let you unscrew the screw without losing the balls. Have you ever bought a new ballnut? They come with just such a tube.
05:14 PM DaViruz: andypugh: yes!
05:14 PM Cromaglious_: ahhh... im on a phone... tiny, tiny type
05:14 PM gregcnc: Enco was a Chicago based industrial supplier, Emco is an Austrian machine tool maker
05:14 PM enleth: andypugh: I guess I have to try
05:14 PM DaViruz: going to kitzsteinhorn tomorrow
05:14 PM andypugh: Emco = Austria, Enco = US(?)
05:14 PM andypugh: DaViruz: Right, you are in Kitzbuhel?
05:14 PM DaViruz: saalbach
05:15 PM enleth: fortunately, this screw is very easy to remove, so I don't have to do it now
05:16 PM andypugh: DaViruz: Ah, yes, I am thinking of the Kitbuhlerhorn
05:17 PM gregcnc: enleth if you're worried about rust on those multiV pulleys, surely you seen a car with much worse and nobody thought to change anything before starting it
05:17 PM Deejay: gn8
05:17 PM Cromaglious_: nite dj
05:17 PM enleth: gregcnc: I've had that belt slip a couple times already
05:17 PM andypugh: DaViruz: How is the snow? Or is that why you are heading for the Glacier?
05:17 PM enleth: as in, slip and start heating up enough to stink
05:19 PM Nick-Shop: any way of deleting lines in terminal - Have a bunch of repeat lines testing index signal
05:20 PM gregcnc: What size are the two pulleys?
05:20 PM enleth: andypugh: besides, I have to take the balls out to remove chips that got stuck in there
05:20 PM enleth: andypugh: so maybe it would just make it easier to reload those nuts
05:20 PM andypugh: Nick-Shop: Not sure I understand the question. Are you working in halcmd?
05:22 PM Nick-Shop: yes and i have about 50 lines of repeated commands I'd like to get rid of
05:22 PM Nick-Shop: terminal then halcmd
05:23 PM andypugh: Nick-Shop: No point. They have been executed already.
05:24 PM andypugh: Today I have been channeling Clickspring: I made a click, with a spring: https://goo.gl/photos/CP1D3QEZd4PFMejB6
05:24 PM DaViruz: andypugh: very mushy i'd say
05:24 PM Nick-Shop: no - im in terminal and calling halcmd setp hm2_5i25.0.encoder.00.index-enable 1
05:24 PM andypugh: DaViruz: Rather late in not a great snow season
05:24 PM DaViruz: yeah
05:25 PM andypugh: How long are you there for?
05:25 PM andypugh: Snow due Sunday
05:26 PM DaViruz: leaving friday evening :/
05:26 PM Cromaglious_: rain due saturday here
05:26 PM andypugh: DaViruz: How do you like skiing in the alps, snow aside?
05:27 PM andypugh: Nick-Shop: So what do you expect to achieve by deleting lines? Are you just trying to clean up the history to copy/paste later?
05:28 PM DaViruz: it's quite tiresome, partly because the people i'm here with are insane.
05:29 PM DaViruz: tiresome in the physical sense
05:29 PM DaViruz: but the scenery is awesome, everythin looks like a post card
05:30 PM andypugh: Well, you are skiing with what my ski-chums call “Scandiwegians” who are known for being insane, both on and off the snow.
05:30 PM DaViruz: and the long slopes are something else. back in sweden you barely get up to speed before you reach the bottom
05:30 PM Nick-Shop: i have about 50 lines in terminal I'd like to erase so I can use the up arrow to get at some previous lines without going throug 50 lines to get at them
05:31 PM andypugh: I have skied in Levi, which wasn’t too bad, but not Alpine standard, definitely.
05:32 PM DaViruz: Levi, is that in finland?
05:33 PM andypugh: DaViruz: Not sure. We were staying in Jokkmokk, but might have driven to Finland.
05:34 PM andypugh: Yes, it is in Finland. I might have to check a map, maybe we went to Are
05:35 PM DaViruz: åre is relatively high, i believe they have almost 1000m drop
05:35 PM DaViruz: levi seems to have 300m-ish
05:39 PM andypugh: Must be Levi. we drove North from Jokmokk
06:15 PM Cromaglious_: weeeee
06:15 PM Cromaglious_: between santa barbara and Santa Maria Kalifornistan
06:29 PM chopper79: Evening
06:33 PM * JT-Shop is officially on vacation for the next 4 days
07:31 PM SpeedEvil: https://www.youtube.com/watch?v=z8PaLepo1Pg - ridiculous optical stuff with LASER frequency combs. Stupid precision interferometry to 100nm over 30km fibre.
07:31 PM SpeedEvil: And then to a fraction of a nm if you switch modes
07:40 PM Wolf_: one hell of a laser tape measure ?
07:40 PM roycroft: laser frequency combs?
07:41 PM roycroft: is that the same as dispersion compensators?
07:43 PM roycroft: oh, no, it's a different thing
07:48 PM Cromaglious_: Finally thru the dead zone....
07:49 PM Cromaglious_: Justed passed Camp San Luis former headquarters California National Guard
07:52 PM Cromaglious_: wooo Eagle! I haven't seen one here in a long time!
07:53 PM Cromaglious_: heh... just passed a murder. (3 Crows)
07:55 PM Cromaglious_: ahhh Morro Bay!
08:32 PM chopper79: Is there a way to use a 12v manual pulse generator with 5v?
08:33 PM chopper79: I have a pair of 12v mpg wheels and trying to figure out if they will work on a 5v supply instead of 12v. I have not taken them apart yet to see what the insides look like.
08:37 PM jdh: voltage divider
08:52 PM chopper79: hmm... I am gonna hook it up to my benchtop with 5v and see what comes out. It is an optocoder so it operates using optos.
08:56 PM CaptHindsight: http://pdf.directindustry.com/pdf/ingersoll-cutting-tools/hole-making-catalog/17869-11078-_93.html should the spotting drill angle be greater than the drill point angle?
08:58 PM CaptHindsight: Another of Murphy's laws: the tiniest hole will completely drain the largest vessel, unless it was drilled with the intention of creating drainage, in which case it will clog.
09:01 PM toner: lol, I will have to remember that one
09:02 PM CaptHindsight: http://www.practicalmachinist.com/vb/general/spotting-drill-bit-159845/
09:04 PM insomnia is now known as CaptObvious
09:13 PM CaptHindsight: http://www.harveytool.com/secure/Content/Documents/Chart_SpottingTheRightAngle.pdf
09:18 PM {HD}: No to wire it up. http://i.imgur.com/m2xoZ3y.jpg
09:19 PM {HD}: Now*
09:19 PM jdh: what vfd is that?
09:20 PM {HD}: huanyang 1.5kw
09:22 PM jdh: I keep meaning to hook my spindle control up, but I never do.
09:23 PM {HD}: I am happy with my layout so far, I will probably change it when it gets moved to the new machine but that will be several months.
09:34 PM chopper79: darn 5v will not turn on the optos in my mpg wheel.
09:34 PM chopper79: Sometimes I wish the 7i77 had a 5v/12v encoder jumper pin.
09:35 PM chopper79: I know it is not as easy as a jumper though
09:35 PM roycroft: just get a cheap 12 ps off ebay
09:36 PM pfred1: or find the limiting resistor and change it
09:37 PM pfred1: optos are easy to figure out
09:39 PM chopper79: I will look into that
09:40 PM pfred1: yeah what you need to do is calculate the current at 12V and make it the same for 5V
09:40 PM pfred1: which means a lower value limiting resistor
09:40 PM pfred1: say 12V is 470 Ohms then 5 will be 330 Ohms
09:41 PM chopper79: got ya
09:41 PM chopper79: Thanks
09:41 PM Cromaglious_: More like 220
09:41 PM pfred1: yeah I think 470 is really 9V
09:41 PM pfred1: but I've run optos down to 220 Ohms
09:41 PM pfred1: a 5V
09:42 PM evilren: theyre all kind of diff
09:42 PM pfred1: finding the current spec on a data sheet works too
09:42 PM evilren: yeah
09:43 PM evilren: current on both sides will affect rise time and overshoot/ripple
09:43 PM pfred1: the opto will have a number on it just get the data sheet
09:43 PM pfred1: they should be separate
09:43 PM chopper79: I thought about just taking the wheel from my 5v one. The one that came with my Mastuura seems a lot better built then my cheap china one.
09:43 PM evilren: pfred1: what do you mean seperate?
09:43 PM pfred1: the transistor side should work on its own power
09:43 PM evilren: right
09:43 PM pfred1: has nothing to do with the trigger side
09:43 PM evilren: but the current of the emitter and the current of the detector both matter
09:43 PM pfred1: or they're jsut not isolated
09:44 PM evilren: trigger side affects how much current happens on the output side
09:44 PM pfred1: yeah no it is light
09:44 PM evilren: um
09:44 PM evilren: its light onto the base of a transistor
09:44 PM pfred1: you lower that limiting resistor and you're going to get sme light for lower voltage
09:44 PM Cromaglious_: Got an ipad with a dead area along the left side of the screen
09:44 PM evilren: theres a spec for multiplication
09:45 PM Crom_: At least I can use the Bluetooth keyboard with it to get around the dead letters
09:45 PM evilren: pfred1: right so for a constant voltage, the resistor effects the current, which effects light emitted, which effects how much current the emitter will pull theough the collelctor resistor, and if it will saturate or not, and how long it will take to saturate
09:45 PM evilren: *collector
09:46 PM Crom_: Aka Rise Time
09:46 PM evilren: yes
09:46 PM evilren: if rise time is too short there will be overshoot and ripple
09:46 PM evilren: the system using the opto might not care so much
09:46 PM evilren: and you can RC the output to kill it
09:46 PM pfred1: heh you don't have to worry about rise time being too short with optos
09:46 PM evilren: but adjusting the emitter and dector resistors can accomplish the same thing
09:47 PM Crom_: Bounces is another thing...
09:47 PM evilren: you do if you are trying to reduce power and are using large resistors
09:47 PM pfred1: optos clean bounse up pretty good
09:47 PM evilren: your layout parasitics play into this too
09:47 PM CaptObvious is now known as MrsScorpio
09:47 PM evilren: tho low power isnt an issue in this case, and i dont think its dudes layout
09:48 PM pfred1: the photoelectric effect is pretty soft
09:48 PM Crom_: My Z home switch is a NO micro switch. Bounce would get me every time.. I had a 470uf electrolytic cap that I threw on there... Now it works right everythme
09:48 PM evilren: in general they do well filtering themselves, especially when used as recommended
09:48 PM pfred1: Crom_ with an opto?
09:48 PM evilren: but right ive done quick and dirty shit and seen rise and overshoot
09:48 PM Crom_: Flea at BOB pin 10, which is through an option
09:49 PM Crom_: Onto
09:49 PM Crom_: Heh Opto
09:49 PM pfred1: I've scoped opto outputs and they have decidedly rounded shoulders
09:49 PM evilren: yeah
09:49 PM BeachBumPete: evening folks
09:49 PM pfred1: optos have shitty waveforms
09:49 PM evilren: and if your emittor collector is too big plus large parasitic capacitance (breadboards), they can rise slower
09:50 PM evilren: if you drive the fuck out of the emitter and get the collector resistor just right they can be pretty sharp
09:50 PM pfred1: I just filter them with a Schmitt inverter
09:50 PM evilren: that plus line inductance means bounce
09:50 PM pfred1: that squares them right up
09:51 PM evilren: right i mean in generals are one of the most well behaved things in this context, but this assumes youre using them within spec
09:51 PM evilren: some low power high sensitivity shit modern shit gonna want diff values than some ancient commodity shit from the 70s
09:51 PM evilren: prob only around because the mil still buys them and they gotta do something with the shit bins
09:53 PM evilren: but right, TL;DR, get datasheet, choosing parts they used for their test curves is usually safest
09:53 PM evilren: dont absolute max shit like a newb
09:53 PM evilren: like, if it says it dies at 20mA, dont feed it 20mA
09:54 PM evilren: like, some are okay up to 50mA, some dont even want 10mA
09:54 PM Crom_: Got to Morro Bay... And find my Folks there as well... Nice... I haven't seen them in about a year
09:54 PM evilren: that sounds neat
09:55 PM Crom_: Sucks being broke
09:55 PM evilren: ikr
09:55 PM evilren: im so over this university shit
09:56 PM Crom_: Heh... One reason we're up this way is to pick up kidlettle from UC Santa Cruz for spring break, then we have to bring her back...
09:56 PM Crom_: There's $100 I don't have right now...
10:05 PM chopper79: Well.. I have to get the darn wheel off the shaft before I can open it up to see the guts. Took the set screw out and wheel will not come off so time to get creative without bending the wheel up.
10:09 PM chopper79: That will be a tomorrow project I guess. Have a good night all.
10:09 PM chopper79: Thank you for the inut
