12:24 AM LeelooMinai: Hmm
12:29 AM LeelooMinai: Now knowing how those pseudo-MIG welders work, that is they have material on the spool and deposit it, an obvious thought is "if they are like 3D printers, why not make the wire thinner, shrink the whole thing, and 3d-print steel", no?
12:47 AM LeelooMinai: Cool, found a way of using one sketch to define placement of features on any component in the design.
12:47 AM LeelooMinai: In F360 that is
12:49 AM LeelooMinai: This was bugging me for a long time.
12:50 AM LeelooMinai: Hmm, I think I did at least.
01:50 AM IchGucksLive: morning from Germany
01:51 AM mire: is anybody home?
01:58 AM mire: I'm trying to restore an old machine of mine to service. It runs Linux cnc on an intel atom board.
01:59 AM IchGucksLive: yes just ask
01:59 AM IchGucksLive: M525
01:59 AM IchGucksLive: im in Germany
02:00 AM mire: guten tag. I'm in california.
02:00 AM Crom: which atom? I have mine on a 1.43ghz atom w/ 2GB rRAM
02:01 AM Crom: mire where in Cali? I'm in Riverside county
02:02 AM IchGucksLive: Crom: so take a bike ride and get the mashine going
02:02 AM mire: D945GCLF2D is the particular board i've got. Video is getting spotty, time to replace or upgrade
02:03 AM Crom: mire heh same board
02:03 AM Crom: mini tix?
02:03 AM Crom: itx
02:04 AM mire: It always worked great. Very good latency scores. I just wonder if I should be upgrading
02:04 AM mire: Placerville
02:05 AM Crom: I'm seriourely thinking about upgrading mine. I'm getting really crappy step gen rates
02:05 AM Crom: Temecula here on I-15 just north of San Diego line
02:05 AM IchGucksLive: im off
02:07 AM mire: It's a 5i20 system so I need a pci slot... servo system so not so sensitive to step gen rates (if i comprehend right)
02:08 AM mire: I'd go for something fanless if I could find one that worked as well
02:08 AM Crom: I'm using parallel port BOB and my wifi is in the PCI
02:08 AM mire: Yours is a stepper system?
02:08 AM Crom: iHSS57-36-20 JMC-motor integrated closed loop steppers
02:09 AM mire: Nice. Mine's an old Hardinge HNC. I'm using the original servos.
02:11 AM Crom: I haven't figured out servo's yet... seems like it's dependent on a x number of bit values
02:11 AM mire: The wizards I met here before were so overpoweringly awesome that they talked me through the whole thing
02:12 AM mire: cradek in particular. I followed his setup. That person deserves a medal.
02:14 AM mire: It worked well for years, but broke when I moved it 4 years ago. Now I'm trying to hack out what I did and make it work again.
02:17 AM mire: Anyway, my scariest error at present is that the 5i20 has two persistent red leds at all times and HAL fails on configuring the first pin.
02:17 AM Crom: so a 24bit position value is good for 16 million locations, a 16 bit 65536 locations
02:19 AM archivist: mire, bed time for for the person you want to talk to about that error
02:19 AM archivist: although it should be in its manual
02:19 AM mire: well sweet dreams to that person I'll try again at a reasonable hour
02:20 AM mire: I suspect I need to force load the hostmot2 firmware or somesuch
02:29 AM archivist: yup PCW will talk you though it
02:30 AM mire: well, glad this is still where the party is at. I'll be back.
02:32 AM Deejay: moin

04:57 AM jthornton: morning
04:58 AM XXCoder: hey jthornton
04:59 AM XXCoder: holy crap its weekend
04:59 AM XXCoder: this week didnt end well jeez
04:59 AM Tom_itx: morning
04:59 AM Tom_itx: chickens get you up early?
05:01 AM archivist_herron: he gets up early to watch the coop door
05:01 AM jthornton: no, I normally get up 4:30-5:00
05:02 AM jthornton: XXCoder: your week starts on Sunday night?
05:02 AM XXCoder: it's 2:30 am ;)
05:02 AM XXCoder: jthornton: no
05:02 AM XXCoder: I only work 4 days
05:02 AM jthornton: ah
05:02 AM XXCoder: today and yeserday was just bad
05:02 AM jthornton: you still at work?
05:02 AM XXCoder: just got home from work
05:08 AM jthornton: I wonder if I can find a LIR2032 locally
05:41 AM miss0r: that should be possible?
05:41 AM miss0r: woah. 30 mins ago.
05:41 AM XXCoder: hey
05:42 AM miss0r: hey
05:42 AM XXCoder: jt probably got out to his shop
05:43 AM miss0r: probally. I'm here stuck at work. Some deuch ordered the wrong enclosures for a project, which means I have to remake all 17 controllers... :-/
05:43 AM miss0r: luckily they have to pay for their mistake
05:45 AM XXCoder: uggggh
05:45 AM XXCoder: talking about mistakes
05:46 AM XXCoder: me, first shirt and third shift guy all missed part being a little too wide
05:46 AM miss0r: yeah. it will set them back around $25k
05:46 AM XXCoder: so one guy modified fixture so it can be used to fix those
05:46 AM XXCoder: and I fixed over 300 of em
05:46 AM XXCoder: other guys fixed around 100
05:46 AM miss0r: :o
05:47 AM miss0r: dang
05:47 AM XXCoder: it sucked
05:47 AM XXCoder: part is normally made 22 minute each
05:47 AM XXCoder: the fix is just one minute and its in arkward machine
05:47 AM XXCoder: so my back hurts
05:47 AM XXCoder: whats you do to fix those enclosures?
05:50 AM miss0r: The enclosures are these cabinets that stand outside. I've build the controllers, with a fuse box and a PLC compartment, with some relays and junctions'n stuff. Apparently they changed the cabinet to a smaller size without letting us know, so I have to take out everything from the boxes i've build it into, and replace them with some different shapes, so they can fit into the new cabinet
05:51 AM miss0r: in other words: the wires have wrong lenghts. Also, theres a gsm modem inside the boxes. I had to make some 90degree din35-rails so that the modem can be tilted on its side in the new boxes... *sigh*
05:51 AM miss0r: Its not bad work. I just hate having to redo things
05:53 AM XXCoder: yeah
05:53 AM XXCoder: do it often enough and its like rolling rock to top of hill lol
05:53 AM miss0r: yeah
05:53 AM miss0r: I got my edm working automatically thou, that is good news :D
05:53 AM XXCoder: nice
05:54 AM miss0r: I can link you a short video from google drive, if you want to see?
05:54 AM XXCoder: sure
05:55 AM XXCoder: as long as you dont use spring camera holder lol
05:55 AM miss0r: I try to keep steady hands :D Its the first try with automatic feed: https://drive.google.com/open?id=0B51cA8Udo5i7RlNsRTBBVUJfVzA
05:56 AM XXCoder: interesting
05:56 AM miss0r: its a start anyway. I did a 5mm hole through a 10mm steel block in aprox 8 minuts
05:57 AM miss0r: So Theres room for improvement. It spends too much time backing up from a short...
05:57 AM jthornton: is that a home made EDM?
05:58 AM miss0r: yep - completely home brewn'
05:58 AM jthornton: cool
05:58 AM miss0r: it will be when I get down to do some proper programming of the PLC. at this point it is too stupid
05:59 AM jthornton: what did you use for the power supply?
05:59 AM XXCoder: isnt edm best way to shape tungstein?
06:00 AM miss0r: jthornton: I used an old tranformer from a UPS, rectified it, fed it to some large caps, and have thoes caps charge a smaller cap parallel to the electrode through a resistor
06:01 AM miss0r: XXCoder: I don't know if its the best way, but it is 'a' way. for now i'll stick to shaping my tungsten on a diamond wheel.
06:01 AM XXCoder: cool :)
06:01 AM jthornton: sounds complicated
06:01 AM XXCoder: I always wanted a movie gold bar made with tungsten
06:02 AM miss0r: Pretty neat transformer actualy. I've build this thing to output 60 volts at 20 amps continously.
06:02 AM XXCoder: so I can show people how silly movie that has em in it is
06:02 AM XXCoder: like one guy pocketing 4 or 5 of em
06:02 AM miss0r: like how easy they make it seem to move it? :)
06:02 AM XXCoder: yah
06:02 AM jthornton: 60 volts ac?
06:02 AM miss0r: thoes "1 liter bars" should weigh in at ~19 something kg
06:03 AM miss0r: jthornton: 60 volts DC.
06:03 AM XXCoder: miss0r: the most accurate one I have ever seen is one movie where scheme is to use BIG dump trucks
06:03 AM XXCoder: and it shows dumps being massive and heavy
06:03 AM miss0r: die hard, eh ?
06:03 AM XXCoder: hmm think so?
06:04 AM miss0r: jthornton: if you are thinking about making one, I would encourage you to do so. It is realy quite easy when you get into it. I started out doing something ridiculously complicated, discarted it, and started over with a simple design that actualy works
06:05 AM miss0r: jthornton: This is basically what my design is: https://pico-systems.com/images/tapedm2.jpg
06:05 AM miss0r: only it is not :]
06:07 AM jthornton: http://www.liming.org/edm/power.html
06:08 AM miss0r: That looks pretty nice. Anyone you know?
06:09 AM jthornton: no, just a google hit
06:15 AM miss0r: I need to design something alot nicer than what I have. For starters: The outrigger I have mounted on my linear z axis is a joke. and the plastic box I have 'could' work, if only it has a bottom that was the same thickness all around. I also need a nice pallet to fit in the bottom of a future tank. All that and not enough hours in a day to go'round
06:21 AM jthornton: http://modelenginenews.org/meng/edm/index.html#links
06:26 AM archivist_herron: hehe last line "This page designed to look best when using anything but IE! "
06:26 AM XXCoder: archivist_herron: is site from 90s? heh
06:26 AM XXCoder: yep it is lol
06:27 AM XXCoder: created in 2006 reardless lol
06:27 AM archivist_herron: people have no clue on the newer sites!
06:28 AM archivist_herron: all mobile friendly and JS and useless on older browsers
06:30 AM archivist_herron: 52 errors on the validator
06:32 AM TurBoss: ald browsers may dead
06:32 AM TurBoss: *old
07:55 AM Frank_10: hi boys
07:56 AM archivist_herron: we have gals too
08:28 AM Loetmichel_: hmm, that BMW isnt that cheap including all the repairs now... -> https://www.spritmonitor.de/de/detailansicht/843554.html
08:56 AM SpeedEvil: :(
08:58 AM archivist_herron: https://en.wikipedia.org/wiki/Lemon_%28automobile%29
09:07 AM Spida: Loetmichel_: what failed?
09:12 AM Loetmichel_: Spida: engine threw a rod
09:12 AM archivist_herron: unexpected scrap part ejection
09:13 AM roycroft: my prius did that earlier this year
09:13 AM roycroft: just a few months after i bought it
09:13 AM roycroft: three holes in the engine block
09:13 AM roycroft: the damage was impressive
09:14 AM Loetmichel_: yeah, it happened at 100mph on the autobahn... not a pleasant experience
09:15 AM Loetmichel_: and a VERY impressive blue smoke cloud
09:15 AM roycroft: i made
09:15 AM roycroft: some nice smoke
09:16 AM roycroft: i could not see at all ahead of me - fortunately i was very familiar with the road i was on and was able to pull over safely
09:16 AM roycroft: i was only doing 90km/h at the time
09:26 AM roycroft: i can see banning morris dancing, but banning line dancing is crossing a line
09:26 AM roycroft: ack, mischan
10:22 AM gregcnc: loetmichel_ the fun of used cars is you get to do all the maintenance the previous owners neglected
10:38 AM ToddZ: Paying for the sins of others, fun.
11:04 AM Tom_itx is now known as Tom_L
11:29 AM CaptHindsight: somehow I had acquired this set of metal pieces http://www.grizzly.com/products/Carbide-Tipped-Tool-Bit-Sets-1-4-20-pc-/G9775 ....
11:29 AM CaptHindsight: someone with a sense of humor posted it as a carbide tipped tool bit set
11:30 AM CaptHindsight: a dull butter knife cuts just as well
11:30 AM archivist: glued on carbide
11:31 AM CaptHindsight: they manage to pre round the edges as well
11:31 AM CaptHindsight: maybe for safety
11:32 AM CaptHindsight: I might try cutting with them in backwards to see if they perform any better
11:32 AM SpeedEvil: are they actual carbide?
11:33 AM CaptHindsight: by carbide do you mean a material harder than the Styrofoam package then yes
11:33 AM jym: CaptHindsight: DUCT TAPE!!!
11:34 AM CaptHindsight: might be good for turning duck tape
11:34 AM CaptHindsight: duck/duct/
11:35 AM CaptHindsight: maybe they are for wood
11:36 AM sync: well meh like all of those you need to grind them before you use them CaptHindsight
11:36 AM Loetmichel_: gregcnc: true. just got the quote for new tires: 400 eur...
11:36 AM Loetmichel_: and the winshield needs to be new, too.
11:36 AM Loetmichel_: and an original suspension if i can muster that
11:37 AM Loetmichel_: and then there are some small rust patches and two dents... and the paint isnt that nice any more...
11:37 AM Loetmichel_: and so the list goes on.
11:39 AM Loetmichel_: but on the lucky side: i was just driving home on the highway... seeing some BLACK clouds over my exit... looking at them and the open canopy in mind i grew more and more anxious if the interiour will get wet... juuust as a was out the exit i parked and pressed the "canopy up" button. The moment i heard the latches in the windshield frame click into place the first fat drops had hit the
11:39 AM Loetmichel_: windshield ;)
11:59 AM roycroft: folks, does anyone know of a good resource to learn about lathe insert tooling?
12:02 PM archivist: sandvik handbook
12:02 PM archivist: downloadable pdf
12:02 PM roycroft: thanks, i'll go get that
12:02 PM archivist: there are a few! navigate with care
12:04 PM roycroft: i found a flashy one
12:04 PM roycroft: i'm trying to find a not flashy one now
12:05 PM archivist: the book I am thinking on is Modern metal cutting Sandvik Coromant 1994 which I have a paper version
12:06 PM archivist: complete list http://www.collection.archivist.info/searchv13.php?searchstr=sandvik
12:08 PM roycroft: it seems like exactly what i'm looking for
12:09 PM roycroft: but i can only find the flash version, except one site that has pdfs, but only individual pages
12:09 PM roycroft: and i don't want to manually download 574 pdfs
12:09 PM roycroft: er, 529 pdfs
12:15 PM archivist: website seems borked by excess JS and crap these days
12:16 PM roycroft: yes
12:17 PM archivist: why dont the modern web jockey's realise what basic sensible html is
12:17 PM roycroft: and you know
12:17 PM roycroft: i'd send them $10 or whatever if they would send me a bloody book
12:18 PM roycroft: hell, i'd pay them $10 if they just let me download a pdf of the book
12:18 PM archivist: I got mine off them at a show
12:18 PM roycroft: but going through the flashy crap to view page by page is completely unacceptable
12:18 PM gregcnc: problem is they stopped updating the full catalog and just release updates
12:18 PM roycroft: i can only assume they're not terribly interested in selling me anything
12:18 PM archivist: also bought the special speed and feeds calculator
12:19 PM gregcnc: i have 128MB 2011 full line
12:19 PM roycroft: there are about a million different inserts out there
12:19 PM roycroft: and i'm interested in starting to use some insert tooling
12:19 PM archivist: the book he wants is the how to rather than the catalogue
12:19 PM roycroft: but i'm not going to buy random inserts to see how they work
12:20 PM archivist: some info is in the catalogues
12:20 PM roycroft: there is a pattern to how the inserts are named
12:20 PM gregcnc: you'll still be doing just that because you can't run them fast enough on manual machine to get the properties they report for CNC
12:20 PM roycroft: and i want to know that
12:20 PM roycroft: so i can understand what each insert does
12:20 PM gregcnc: grades tell you want the insert does
12:20 PM CaptHindsight: indexable with inserts vs hand ground now there's a discussion
12:20 PM roycroft: i could at get a sense of what they're supposed to do, gregcnc
12:21 PM gregcnc: not really
12:21 PM roycroft: at least get a sense
12:23 PM IchGucksLive: hi from Germany
12:24 PM CaptHindsight: IchGucksLive: what are you making today?
12:24 PM roycroft: this seems like one of those "you can't learn - you have to already know" things
12:24 PM gregcnc: insert tooling has gotten so specialized, some grades work for almost any application, but some are very specific
12:24 PM gregcnc: it took me years of looking at catalogs to get a general idea, even them when hunting on ebay i check the catalogs
12:25 PM roycroft: there seems to be a pattern for how the inserts are named
12:25 PM gregcnc: CCGT DCGT etc?
12:25 PM roycroft: rake angle, nose radius, chipbreaker features, etc embedded in the pattern
12:25 PM gregcnc: consistently variable between manufacturers
12:26 PM roycroft: it seems to me that if i try an insert tool and i find there is some aspect of it i'd like to tweak i should be able to order another, knowing that one parameter is different, but the rest is the same geometry
12:27 PM roycroft: if it varies between manufacturers then i'd be fine with ordering a different insert from the same manufacturer, if i could be confident that know how it's different from the one i have
12:27 PM roycroft: i'm not exactly looking for "turning tool inserts for dummies"
12:27 PM roycroft: but something that would give me an idea where to start, and develop a path for finding what i want
12:28 PM gregcnc: download the general turning catalog
12:28 PM roycroft: i can't
12:28 PM roycroft: it's not downloadable
12:28 PM roycroft: it's viewable page-by-page with flash
12:29 PM roycroft: which is why i say they seem to not want to sell me anything
12:29 PM gregcnc: i just downloaded it
12:29 PM roycroft: when i went there all i could find is the flash thing
12:29 PM gregcnc: http://tinyurl.com/y79vtr9f should be first link
12:30 PM IchGucksLive: CaptHindsight: large 7-segments
12:30 PM roycroft: weird
12:30 PM CaptHindsight: IchGucksLive: segments of what?
12:30 PM IchGucksLive: the displays
12:30 PM roycroft: going to the sandvik website i searched for turning catalog, turning inserts, etc. and all it kept doing was taking me to the flash version
12:31 PM roycroft: thanks
12:31 PM gregcnc: there is a downloads link right at the top of their site
12:31 PM roycroft: whenever that finishes loading it will probably be just what i want
12:31 PM roycroft: aah, i was on sandvik.se
12:31 PM archivist: downloads did not work on my browser, I got a blank
12:31 PM IchGucksLive: CaptHindsight: not as big but large http://www.dontclickthis.de/category/projects/huge-7-segment-clock/
12:32 PM roycroft: not sandvick.coromant.com
12:33 PM gregcnc: yes even that site, anyway
12:34 PM CaptHindsight: woo hoo the new bark stopper just arrived
12:34 PM CaptHindsight: the dog next door is really acting up today
12:34 PM gregcnc: hmmmm
12:35 PM gregcnc: steak or training whistle
12:35 PM archivist: shot gun
12:35 PM CaptHindsight: why the hell do people bring theirs dogs to work?
12:36 PM gregcnc: cleaning the coolant tank does indeed suck
12:36 PM CaptHindsight: we always seem to end up with a neighbor with a barking dog that is only trained by the owner yelling the occasional "shut up"
12:36 PM * roycroft 's browser is still loading the catalog
12:37 PM roycroft: i'm not sure what to make of my new next door neighbor
12:37 PM roycroft: he has a yippie dog, like my previous three neighbors
12:37 PM IchGucksLive: Loetmichel_: on elektronic transistor
12:37 PM roycroft: but his is only there part time
12:37 PM roycroft: he smokes, however
12:37 PM roycroft: and the smoke blows straight from his back patio into my bedroom window
12:37 PM roycroft: so i'm happy that i only have part-time barking
12:38 PM roycroft: but can't stand that my bedroom is full of cigarette smoke all the time
12:40 PM roycroft: yes, i think that sandvik catalog will be useful
12:40 PM gregcnc: you'll only need a few grades for manuals turning. a sturdy grade for steels, aluminum grade, and maybe something for finishing steel if you don't want to kill aluminum inserts on steel
12:41 PM roycroft: but if the insert naming schema varies from manufacturer to manufacturer i guess i'll have to find catalogs for an others whose products i might want to try
12:41 PM roycroft: yes, i don't anticipate needing many
12:41 PM roycroft: probably a half dozen or ten different inserts should cover everything i would do
12:41 PM roycroft: including threading
12:41 PM roycroft: and parting
12:41 PM roycroft: i anticipate i'll be turning more brass than aluminium
12:42 PM roycroft: and i'll still be grinding my own hss tooling
12:42 PM gregcnc: start with pg A112
12:42 PM roycroft: but i'd like to give inserts a go
12:43 PM roycroft: do the inserts generally interchange with any tool holders of the proper type?
12:43 PM roycroft: i.e. a triangular screw type from one vendor would interchange with the same type from another vendor?
12:44 PM gregcnc: yes, in some sizes you have to waht for insert thicknes
12:44 PM roycroft: sure
12:45 PM roycroft: and yeah, that code key chart you pointed me to is exactly the thing i'm looking for
12:46 PM roycroft: unfortunately, as i have a small lathe with a small qctp, i'm somewhat limited in the tool holders i can use
12:46 PM gregcnc: oops that one was specific to capto line, A16 is the inserts
12:46 PM roycroft: 1/2"x1/2" is the biggest toolholder i can handle
12:47 PM gregcnc: I use 1/2" holders with 1/4" IC inserts
12:47 PM LeelooMinai: Everyone was asleep yesterday, but, I will throw a random thought here: since MIG is basically working like 3D printer with feeding spools of wire and depositing them, wouldn't it be logical to try to shrink it a bit, make the wire thinner, and make metal 3D printer this way for smallish price?
12:47 PM gregcnc: I've never felt the need to be taking Abom size cuts
12:48 PM roycroft: i'm not in a hurry
12:49 PM roycroft: if my income were depending on my machining work i'd probably be in more of a hurry
12:49 PM roycroft: but at this point it's not
12:50 PM roycroft: besides, my lathe is not big enough or beefy enough to be in a hurry
12:50 PM gregcnc: A524 gives you grades overview
12:58 PM IchGucksLive: the MAX7219 (or MAX7221) simply doesn't work with common anode displays.
01:03 PM IchGucksLive: ok what i do not understand is how does the adressing work with more then one max7219
01:08 PM * LeelooMinai catches herself watching YouTube video "Why Jamie Hyneman wears a beret" and thinks "how did I get here..."
01:09 PM CaptHindsight: IchGucksLive: https://www.maximintegrated.com/en/app-notes/index.mvp/id/141 more than one 7219?
01:11 PM LeelooMinai: Er...
01:11 PM CaptHindsight: MUX on the /CS
01:12 PM LeelooMinai: Who on earth would use this IC... It's $12 and you can as well use simple LED driver IC and any cheap micro.
01:14 PM LeelooMinai: It's also ancient - 2002.
01:15 PM CaptHindsight: they also have a scan limit register for cascading multiple 7219's
01:16 PM IchGucksLive: LeelooMinai: i got 5 ic on 1USD
01:16 PM IchGucksLive: its cool only 3 pins
01:16 PM IchGucksLive: but its the wrong direction on common anods
01:16 PM LeelooMinai: Well, I meant "normal" price: https://octopart.com/search?q=max7219
01:18 PM LeelooMinai: For fun you could also use one FPGA to drive zillion of LEDs, but that is for nerds mostly and requires a lot of knowledge.
01:19 PM LeelooMinai: Since nowadays you can get FPGAs for sub $10 or even $5
01:21 PM LeelooMinai: Maxim tends to have many nice ICs for fairly specialized cases, but they are usualy overpriced and often not a lot in stock.
01:23 PM LeelooMinai: IchGucksLive: You need common anode? I checked what I used in old projects: seems TLC59282DBQR: 16-Channel, Constant-Current LED Driver with 4-Channel Grouped Delay
01:24 PM LeelooMinai: From what I see it's only $2, from Texas Instruments
01:25 PM LeelooMinai: https://www.digikey.ca/product-detail/en/TLC59282DBQ/296-31393-ND/2600366?curr=cad&WT.z_cid=ref_octopart_dkc_buynow&site=us
01:25 PM LeelooMinai: You can chain them.
01:25 PM IchGucksLive: LeelooMinai: it is not a problem to harvest all the pins for the simple led driver lig
01:25 PM LeelooMinai: So any number of those + micro.
01:27 PM LeelooMinai: It was old project, but I usually OCD about each part, so I trust at that time it was a good choice. Seems it has constant current drivers, which is nice.
01:29 PM LeelooMinai: IchGucksLive: Right, I was just saying that with FPGA you can do pretty crazy things at high speed, even if you dedicate one pin/pad to one LED (since FPGAs tend to have tons of GPIOs).
01:30 PM LeelooMinai: Or you can multiplex to save pins, with high speeds.
01:33 PM LeelooMinai: Hmm, all news are about UK "surprising election results" - wonder what that's about.
01:42 PM LeelooMinai: Noooo.... https://www.digitaltrends.com/cool-tech/ability3d-metal-printer-ces-2017/
01:53 PM IchGucksLive: im off Gn8
01:57 PM * JT-Shop takes a Greek yogurt break
01:58 PM LeelooMinai: Make sure it's not Chobani yogurt:p
02:55 PM TurBoShop: Hello
02:55 PM TurBoShop: I'm trying to jog with python
02:55 PM TurBoShop: I'm using c.jog(linuxcnc.JOG_INCREMENT, jogmode, axis, speed, increment)
02:56 PM LeelooMinai: I can see how there can be problems with that:p
02:56 PM TurBoShop: and got JOG_INCR command.com !teleop bad joint_num cmd=48 , whitout home the machine and nothing when homed
02:57 PM cradek: whoa is that an accurate transcription of the error message?
02:58 PM TurBoShop: "JOG_INCR command.com !teleop bad joint_num cmd=48"
02:58 PM TurBoShop: this is the error message
02:58 PM TurBoShop: when the machine is not homed
02:59 PM TurBoShop: oviously nothing moves
03:00 PM TurBoShop: sorry afk
03:00 PM TurBoShop: back in 5 min
03:00 PM cradek: so it says bad joint_num
03:02 PM cradek: so what are jogmode and axis?
03:04 PM TurBoShop: doc says http://dpaste.com/1SX29PT
03:05 PM cradek: heh I mean in your call that's failing
03:05 PM TurBoShop: oh
03:05 PM TurBoShop: c.jog(linuxcnc.JOG_INCREMENT, False, 0, 100, 1)
03:06 PM cradek: ok False means to jog an axis, but you don't have axes unless you're homed and in teleop mode
03:06 PM TurBoShop: ah
03:06 PM cradek: maybe you want to jog a joint instead
03:06 PM TurBoShop: so I'm not in teleop mode?
03:06 PM TurBoShop: oh
03:06 PM cradek: you sure aren't if you're not homed, because you can't switch to teleop while unhomed
03:07 PM TurBoShop: so better to jog a joint=?
03:07 PM cradek: well I don't know what you're trying to do
03:07 PM TurBoShop: a mpg
03:07 PM TurBoShop: jog wheel
03:07 PM TurBoShop: so axis better ...
03:07 PM TurBoShop: :P
03:08 PM cradek: so hook it up to the jogwheel inputs!
03:08 PM cradek: we have *really good* jogwheel support
03:08 PM TurBoShop: but i'm over serial
03:09 PM TurBoShop: setup :
03:09 PM cradek: recommend fixing that and using a realtime interface for the jogwheel
03:09 PM cradek: a laggy jogwheel is terrible
03:10 PM TurBoShop: I wan't to try it :P
03:10 PM cradek: cheers
03:10 PM TurBoShop: its rs232 at 1000000
03:11 PM cradek: you're not going to try to send an incremental jog for every click are you?
03:11 PM TurBoShop: i'm sending steps and dir
03:11 PM TurBoShop: not incremental
03:11 PM cradek: TurBoShop> I'm using c.jog(linuxcnc.JOG_INCREMENT
03:12 PM TurBoShop: oh
03:12 PM TurBoShop: so yes
03:12 PM TurBoShop: :D
03:12 PM TurBoShop: that means that
03:12 PM cradek: that will not ... work well
03:13 PM cradek: but! I bet you can get it working enough to try it, if you get your modes right
03:13 PM TurBoShop: ok thanks
03:17 PM JT-Shop: yea found 3 sticks of 1.5" 8020
03:19 PM TurBoShop: It moves!
03:19 PM TurBoShop: weee
03:35 PM LeelooMinai: Hmm, naming inquiery: how would you call everything related to a side of rail - that is rail with blocks and some beam it rests upon, etc.?
03:38 PM enleth: rail assembly?
03:40 PM LeelooMinai: Right, I am just thinking exactly about that, but considering if it will not be redundant if I start naming components with nested components "Assembly"
03:40 PM LeelooMinai: Could shorten i to "Ass" I guess, but that's weird:)
03:40 PM LeelooMinai: What I mean that "assembly" in CAD is a generic term.
03:41 PM enleth: sub-assembly?
03:41 PM LeelooMinai: Right, I am just seeking something more focused. Same way as "X stage" is better than "X assembly"
03:42 PM enleth: not sure if there's something for rail sides that's more appropriate
03:43 PM enleth: as for "ass", the HRs at my previous job had a problem with a piece of company directory management software that wouldn't take long job description strings, so they shortened "associate specialist" to "ass specialist"
03:43 PM LeelooMinai: Right, maybe there's not - will have to make something up.
03:44 PM enleth: and supposedly there was one "associate business analyst" who got called "ass. business anal."
03:44 PM XXCoder: heys
03:46 PM LeelooMinai: enleth: Did they put those on bussiness cards too? :)
03:47 PM kyle___: guys guys guys I managed to weld last night
03:47 PM enleth: watercooler stories reported this almost happend when cards were ordered en masse with an excel sheet exported from the directory
03:48 PM LeelooMinai: kyle: I "welded" first time in my life yesterday too:) Well, more like "deposited metal on metal".
03:48 PM kyle___: haha, yeah, that's how my first day with the welder went too
03:48 PM kyle___: I'm not sure if I just got slightly better or the new sticks I got are way better
03:48 PM kyle___: probably a little of both
03:48 PM LeelooMinai: So, high five I guess, we are now outside of at least 3 standard deviation of bell curve as to human experience with welding:p
03:48 PM kyle___: but I actually held an arc long enough to blow my breaker
03:48 PM kyle___: damn right!
03:49 PM kyle___: on the path to greatness
03:49 PM kyle___: my weld may resemble a hemorrhoid, but it's MY hemorrhoid
03:49 PM kyle___: ... not literally
03:50 PM LeelooMinai: In fact, I am buying pseudo MIG welder which is on sale for $199 - yes, I know, sounds cheap, but people seem to give it good reviews.
03:50 PM LeelooMinai: And that's CAD so more like $150
03:52 PM LeelooMinai: http://www.canadiantire.ca/en/pdp/mastercraft-mig-and-flux-welder-0588195p.html#srp
03:53 PM enleth: LeelooMinai: looks like a dozen other chinese MIGs
03:53 PM LeelooMinai: Seems like one can upgrade it with gas later.
03:54 PM enleth: they weld, they usually don't blow up, a friend of mine who's a professional welder keeps something like this in the trunk of his car in case he gets called with a surprise job
03:54 PM LeelooMinai: Yes, well, all others seemed to be $600 or more.
03:55 PM XXCoder: enleth: pretty good idea
03:55 PM LeelooMinai: So I thought I cannot afford it at all, but this sale gives me a chance to try it.
03:56 PM kyle___: if you're not doing it professionally then I don't see a problem with such a welder
03:56 PM XXCoder: lee if reviews is great then go for it
03:56 PM XXCoder: also look up on mods for it
03:56 PM kyle___: if you're doing it professionally you should invest in a better welder so you can further increase profits ;)
03:56 PM XXCoder: see if theres standard problems with tht one
03:56 PM LeelooMinai: No, it's just hobby - probably will not use it very often.
03:56 PM FinboySlick: Sheesh, there's 8 of 'em at the store right next to the office.
03:57 PM FinboySlick: I'm tempted too.
03:57 PM LeelooMinai: FinboySlick: Lol, go for it - everyone will be welding here soon:p
03:57 PM XXCoder: not me lol
03:57 PM FinboySlick: LeelooMinai: It's pre-fit for gas upgrades or is it more of a hack?
03:58 PM LeelooMinai: I once said that I am willing to learn a lot of skills, but will never attempt to weld - seems I lied.
03:58 PM LeelooMinai: FinboySlick: No, it's capable of gas, just you have to get the bottle, regulartor etc. separatelly.
03:59 PM LeelooMinai: Once person in the comments wrote about it, and I looked into the PDF too.
04:00 PM LeelooMinai: One good thing about Mastercraft is that although made in China, it has decent manuals in proper English, etc.
04:00 PM FinboySlick: Not always.
04:00 PM FinboySlick: Definitely not their battery chargers ;)
04:00 PM LeelooMinai: And you have 3 years warranty, etc. - seems even for a welder.
04:01 PM LeelooMinai: Right, well, I don't know - I am just talking about tools I got from there, like angle grinder, drill, saws, etc.
04:01 PM LeelooMinai: Usually if you get those on sale, they are ok value.
04:01 PM FinboySlick: Using cheap tools to build proper tools is an appealing concept ;)
04:02 PM FinboySlick: No manufacture is going to put as much attention to detail into making a tool as the person using it.
04:02 PM LeelooMinai: Well, ideally I would build my CNC with another CNC, but had to start with drill press.
04:03 PM LeelooMinai: At least you have a plan there - not verty efficient, but as they sell in chess "A bad plan is better than no plan" :)
04:03 PM LeelooMinai: say*
04:03 PM SpeedEvil: LeelooMinai: have you seen ...'s series?
04:03 PM SpeedEvil: ah myfordboy
04:03 PM enleth: XXCoder: his logic is that he's good enough he can do a proper weld even with an el cheapo welder as long as it's not outright malfunctioning, and he'd know immediately it's acting up - so he's using it when he's called in the field because it's small, light and not a problem if it gets stolen
04:04 PM XXCoder: indeed. while most planned repairs he has regular one
04:04 PM LeelooMinai: enleth: But, is that welder powered by battery or what...
04:04 PM FinboySlick: LeelooMinai: Hahaha, have you looked at the 'helmet' and brush that come with it?
04:05 PM LeelooMinai: lol, yes, they are there probably to meet some lovest safety standard - useles.. I have auto-darkening helmet from there that is on sale for $115.
04:05 PM enleth: LeelooMinai: obviously he needs a power uplink or a generator, the customer has to supply those
04:05 PM FinboySlick: Reminds me of CaptHindsight's favorite picture: https://cdn.theatlantic.com/assets/media/img/photo/2013/05/chinese-diy-inventions/c08_RTR1ECDC/main_900.jpg?1420508178
04:05 PM LeelooMinai: I mean can you imagine anyone holding a face shield on a stick:)
04:05 PM enleth: LeelooMinai: thing is, he's mostly working at his place and shipping stuff to the customer, but sometimes he's called to come in and do repairs in place
04:06 PM enleth: so he keeps a cheap shit MIG and a cheap shit TIG with two small bottles in his car
04:07 PM LeelooMinai: enleth: Ok, but I was not kidding - in that Jamie mythbusters video I think he was saying that his MIG welder can work 30 minutes on internal batteries or something like that...
04:07 PM LeelooMinai: So in theory you could fix a car in the middle of nowhere.
04:07 PM SpeedEvil: My welder project I was tempted to add a smallish lithium
04:08 PM LeelooMinai: Well, older car - probably modern ones no one can fix anyways:p
04:09 PM enleth: LeelooMinai: I wouldn't be surprised if you could power up a modern inverter welder with a 24V from a truck battery/alternator
04:11 PM LeelooMinai: Hmm, on the other hand my tiny hobby 50W arc welder devours 2kW from mains, so I don't know... Maybe those MIG ones are more efficient.
04:11 PM enleth: you mean 50A?
04:11 PM LeelooMinai: Right
04:12 PM enleth: the arc voltage is going to be 20-60V, AFAIR
04:13 PM enleth: which requires 1000-3000VA to keep the arc going at 50A
04:13 PM enleth: just about right with 2kW
04:13 PM LeelooMinai: Right, so the big ones must be pretty scary...
04:14 PM LeelooMinai: Turn them on and the power goes off in the neighbourhood?
04:14 PM SpeedEvil: By 'smallish lithium' - I meant one that could do ~100A@60V
04:15 PM LeelooMinai: Right, that's not exactly small.
04:15 PM SpeedEvil: couple of kilos
04:15 PM enleth: I've got a 250A MIG around here, pulls up to 9kVA
04:15 PM enleth: it's hooked up to 3 phase
04:16 PM LeelooMinai: "no thx"
04:16 PM enleth: it will work off of one phase too, but the current draw gets ridiculous
04:19 PM roycroft: my gtaw welder is 250a, and runs on 250vac single phase
04:20 PM roycroft: the extension cord i made to use the machine in my welding shop is so heavy i can hardly lift it, so i use a garden hose reel cart to store it and move it around
04:20 PM roycroft: 100' of 6a soow is pretty heavy
04:21 PM SpeedEvil: :)
04:21 PM XXCoder: heavy, man.
04:21 PM enleth: it's the nice thing about switchmode supplies - they can be easily made to accept just about anything on the input side if designed well
04:22 PM enleth: a 3-phase input inverter will just take one or two phases as well
04:22 PM roycroft: the outdoor wifi radios we use are like that
04:22 PM enleth: and should take DC if the voltage is high enough
04:22 PM roycroft: i can feed them -48vdc
04:22 PM roycroft: or 50-480vac single or three phase
04:22 PM kyle___: my car has a battery capable of 360A at 300v :P
04:22 PM roycroft: they just work with whatever i feed them
04:23 PM kyle___: you can get some really crazy discharge rates out of lithium ion cells
04:23 PM kyle___: especially in aggregate with lots of them in parallel
04:23 PM XXCoder: know whats better? caps. lol
04:23 PM kyle___: oh yeah
04:23 PM kyle___: I don't know of any ultracap powered cars yet though
04:23 PM enleth: there was this crazy russian on youtube who welded with 230VAC directly from the power outlet - using a salt water bucket as a current limiter
04:24 PM kyle___: if it looks stupid but it works, maybe it's russia
04:24 PM LeelooMinai: That's not a "crazy ruissian" - just a normal one.
04:24 PM roycroft: excuse me
04:24 PM roycroft: but isn't "crazy russian" redundant? :)
04:24 PM roycroft: at least all of the ones on teh youtube are crazy
04:24 PM kyle___: our sample set may be biased
04:25 PM roycroft: putin is crazy like fox
04:25 PM kyle___: although a large fraction of my coworkers are russian, so... I can corroborate this
04:25 PM XXCoder: wow. LEGO just went 100% renewable energy
04:25 PM XXCoder: and they ceberated by building giant lego windmill.
04:25 PM XXCoder: https://futurism.com/lego-just-hit-their-100-renewable-energy-goal-3-years-ahead-of-schedule/
04:26 PM LeelooMinai: So now what... They have to leave US market? :)
04:26 PM roycroft: have they figured out how to harness the energy from the loud "ow!" people make when they step on legos?
04:26 PM kyle___: is ABS recyclable? can't remember
04:26 PM roycroft: yes, but i don't know if it's lossy
04:26 PM XXCoder: kyle___: it is. not perfectly but yes
04:26 PM kyle___: nice
04:26 PM roycroft: lossy recycling is better than no recycling, but not much better
04:27 PM XXCoder: LEGO is still working on better plastics that is not from oil
04:27 PM LeelooMinai: How about eatable lego:)
04:27 PM XXCoder: I sent link directly to leader of that dept lol lemme see if I still have that link
04:27 PM XXCoder: http://www.pnnl.gov/news/release.aspx?id=1029
04:27 PM enleth: it would be cool if they managed to produce PLA that stands up to their ABS mixes
04:27 PM XXCoder: how about abs that is not from oil?
04:28 PM roycroft: they could make legos out of waffles
04:28 PM XXCoder: car fuel, diesel, car oil so on, just like oil?
04:28 PM roycroft: then people would say "leggo my lego"
04:28 PM XXCoder: only its grown then converted to crude oil
04:28 PM kyle___: anything is edible if you're brave enough
04:28 PM XXCoder: since its co2 from air, it means any oil burnt from that simply returns co2 to air
04:28 PM XXCoder: rather than grab new from ground
04:29 PM LeelooMinai: "-- Stop playing with your Lego, the dinner is ready! -- I am not hungry any more, mom"
04:29 PM XXCoder: lol
04:29 PM kyle___: oil from algae is cool, but doesn't seem cost-effective
04:29 PM XXCoder: would be pretty amazing if someone invented hard plastic that is indeed ediable.
04:30 PM XXCoder: kyle___: it can be, easily
04:30 PM XXCoder: expecially when oil prices go up
04:30 PM kyle___: yeah
04:30 PM kyle___: I'm not counting on that any time soon though
04:30 PM LeelooMinai: XXCoder: I thought McDonald already did:p
04:30 PM XXCoder: lol
04:31 PM kyle___: not until saudi arabia is done for, that is :P
04:32 PM XXCoder: wow end result of lego windmill is pretty large allright
04:32 PM XXCoder: looks like pure lego also they usually has supports inside
04:48 PM Deejay: gn8
05:03 PM TurBoss: cradek: I got all working fine
05:04 PM TurBoss: I only jog 0.1 2 or 3 steps
05:04 PM TurBoss: https://www.youtube.com/watch?v=jq_bu8iFJ6A
05:40 PM LeelooMinai: TurBoss: lol, nice, but your hand and fingers will eventually fall off using it:)
05:40 PM TurBoss: what?
05:41 PM LeelooMinai: I mean it's not very ergonomic:)
05:41 PM TurBoss: :-D
05:41 PM TurBoss: is cheap
05:42 PM LeelooMinai: For now I just use one of those little RF keyboards - it works fine.
05:42 PM TurBoss: I'm bored of mine
05:42 PM TurBoss: to slow
05:43 PM TurBoss: sometimes does not jog
05:43 PM LeelooMinai: Right, it's not ideal - it has some kind of power saving feature and need extra press to wake it up.
05:44 PM LeelooMinai: But, is wireless small and you can control linuxcnc features with it.
05:46 PM TurBoss: is on my hate list
05:46 PM TurBoss: windows > USB > wireless
05:46 PM LeelooMinai: TurBoss: If I was building mine, I would probably use mechanical switched (one can buy them individually from ali, etc.)
05:46 PM LeelooMinai: switches*
05:47 PM TurBoss: you mean the jog wheel?
05:47 PM TurBoss: I could buy a 13€ jog wheel but I did have the encoder arround
05:47 PM LeelooMinai: No, I mean to control all the exis. I don't get that jog wheel thingy - but I have not looked at it uet.
05:47 PM TurBoss: ahhh
05:47 PM TurBoss: yes
05:48 PM LeelooMinai: I mean I know what it is, etc., but not sure what it is supposed to help with.
05:48 PM TurBoss: I need it to touch off Z
05:48 PM TurBoss: with the papper
05:48 PM TurBoss: :)
05:49 PM LeelooMinai: Looks like a "paddle" thing they had for 8-bit Ataris in 80s - no one really used them for anything than Pong...
05:49 PM TurBoss: :D
05:49 PM LeelooMinai: TurBoss: Did you see my temporaty z-touch thing?
05:49 PM TurBoss: no
05:49 PM TurBoss: showme
05:51 PM LeelooMinai: http://i.imgur.com/FpV7w88.jpg
05:51 PM TurBoss: ah yes i saw it
05:51 PM LeelooMinai: But, you could buy $4 "digital hole depth" measure or something - I have one and they are ok.
05:52 PM LeelooMinai: Or vandalize a calliper even:)
05:53 PM LeelooMinai: I will make something awsome eventually, but for now it worked ok.
05:54 PM LeelooMinai: I also thought that one could maybe use one of those music controller pads.
05:54 PM LeelooMinai: A lot of them with buttons and extra stuff: http://www.wirerealm.com/wp-content/uploads/2014/04/Akai-MPD18-Best-MIDI-Pad-Controller-1024x707.png
05:55 PM TurBoss: too expensive
05:55 PM LeelooMinai: Some even have programmable RGB colors for each key: http://tomleemusic.ca/media/catalog/product/cache/1/image/1500x/040ec09b1e35df139433887a97daa66f/1/7/178291_5.jpg
05:56 PM LeelooMinai: Right, they may be too pricey.
05:56 PM LeelooMinai: I had RumblePad once working with linuxcnc, but it was not really nice imo.
05:58 PM LeelooMinai: So, I would just desing something myself probably - mill a case from aluminum, use mechanical switches, all where I want, etc.
05:59 PM TurBoss: cool
05:59 PM TurBoss: thats the spirit
06:01 PM LeelooMinai: Damn, those music people went "full retard" with all of those pads: https://www.google.ca/search?q=music+controller+pad&source=lnms&tbm=isch&sa=X
06:07 PM CaptHindsight: http://imgur.com/gallery/dI8xnCj what my day is now like

06:26 PM bruno26: Hi. I am a newby with linuxcnc. I can't create an username. I don't receive email for confirmation. Thanks
06:26 PM LeelooMinai: o_O
06:28 PM CaptHindsight: bruno26: registering for an account on the forums?
06:28 PM bruno26: Yes, I talk about the forum of Linuxcnc
06:29 PM LeelooMinai: bruno26: Did you check junk/filters?
06:29 PM LeelooMinai: In your email client that is.
06:31 PM bruno26: Yes, i checked the filters. I tried with another adress email, and it's the same thing.
08:48 PM Crom: ugh... yet another duel with the Veterans Adinistration today... got hung up on 3 times... last lady was so sweet! She got an inquiry sent off...
08:48 PM Crom: yea my STM32's are on their way...
08:48 PM Crom: 72 Mhz nano sized micro controller...
08:50 PM XXCoder: I heard VA is a nightmare
09:04 PM Crom: it is...
09:05 PM XXCoder: sucks
09:13 PM LeelooMinai: Crom: L4s?
09:16 PM Crom: STM32F103C8T6 ARM STM32 Mini System http://www.ebay.com/itm/232261897237
09:16 PM LeelooMinai: Crom: :(
09:17 PM Crom: the Chinglish in the description is damn funny...
09:18 PM LeelooMinai: Crom: Those ARMs are kind of ancient.
09:18 PM XXCoder: its high quality
09:18 PM XXCoder: like everything else there is
09:19 PM XXCoder: "JTAG is now threatening to eliminate trends"
09:19 PM XXCoder: man them villian jtags
09:19 PM malcom2073: "core board raises all the I/O port resources."
09:19 PM malcom2073: Raise the roof on them resources!
