12:01 AM Mikeee: I'm thinking of picking up a used unit for fun and to learn
12:05 AM Mikeee: https://www.ebay.com/itm/FANUC-6-Axis-Heavy-Duty-Robot-Control-System-Used-AM15644/123529552776?hash=item1cc2ef6388:g:8WsAAOSwbYZXauqi
12:07 AM rue_shop1: this force feedback is AWESOME
12:08 AM rue_shop1: I cant wait to start using it with air muscles
12:08 AM zhanx: nice
12:09 AM zhanx: shipping weight on the steppers for 12 bucks is off
12:09 AM zhanx: 2 pounds for 10?
12:09 AM rue_shop1: tom realized the price is ea
12:09 AM zhanx: well that was a waste then
12:09 AM rue_shop1: they just threw a pic of 10 in the listing
12:10 AM rue_shop1: :/
12:10 AM zhanx: i will dispute it and keep the 1
12:10 AM zhanx: they showed 10 I should have got 10 and it said lot
12:10 AM rue_shop1: they didn't say how many in the lot tho eh?
12:10 AM zhanx: true but its ebay
12:14 AM rue_shop1: this is great, if you hold one servo and try to turn the other, the power transformer gets all noisy and the led for the power rail dimms a bit
12:15 AM rue_shop1: so, I'v got what I'm gonna be able to get out of it
12:15 AM rue_shop1: but you can really tell its fighting now
12:15 AM rue_shop1: the other motors hit max torque at a level that left a person unsure
12:16 AM Mikeee: 240v robots are so much more expensive /=
12:16 AM zhanx: like that one is cheap
12:17 AM Mikeee: what one
12:17 AM rue_shop1: $2400 is almost scrap value
12:17 AM zhanx: the one you linked to
12:17 AM zhanx: 2400 is a lot of money still
12:17 AM Mikeee: the one I linked to was super cheap
12:18 AM Mikeee: fanuc robots go for a ton
12:18 AM rue_shop3: ABB is a real robot :)
12:20 AM rue_shop1: ok, so I need to split my force controller into two then
12:21 AM rue_shop1: I keep losing the documentation for these projects
12:21 AM * rue_shop1 looks at the mountain of papers in the corner
12:21 AM rue_shop1: yup, hopelessly lost
12:22 AM zhanx: yep
12:27 AM zhanx: rue don't worry i am making a robot arm:D
12:27 AM zhanx: design is open now
12:27 AM zhanx: make 8 weeks to print
12:27 AM zhanx: or 9
12:28 AM zhanx: still working on the idea for a gripper tho
12:29 AM zhanx: gonna use one of the NI boards on it
12:33 AM rue_mohr: you dont have to print every part of it
12:33 AM rue_mohr: resist the dark side
12:33 AM rue_mohr: didn't you say you have a cnc?
12:34 AM rue_mohr: why is that rattling around in the back of my head
12:37 AM zhanx: that was stolen
12:37 AM rue_mohr: !?!?! someone stole a cnc!?
12:37 AM zhanx: i had a A12 thunderbolt cnc that was stolen as part of my shipment of household goods
12:38 AM rue_mohr: crap, you checked ebay, right?
12:38 AM zhanx: yep
12:38 AM rue_mohr: and craigslist?
12:38 AM rue_mohr: arg
12:38 AM zhanx: yep
12:38 AM rue_mohr: ok, well, I have the designs for the 3d printed parts to make a cnc
12:38 AM rue_mohr: like mine
12:38 AM zhanx: k
12:38 AM zhanx: send it, i would rather make a cnc then print all this
12:39 AM rue_mohr: arg, my site is up to 1G
12:39 AM rue_mohr: zhanx, it takes a lot of welding
12:39 AM rue_mohr: have 3 nema23?
12:39 AM zhanx: 110v ok? I gas shielding
12:39 AM zhanx: I can order them
12:39 AM rue_mohr: printers
12:40 AM rue_mohr: usually main drive from HP
12:40 AM zhanx: k
12:40 AM zhanx: you know i collect printers for motors
12:41 AM zhanx: but i am torn, wax printer for casting or cnc
12:41 AM zhanx: or both really, cast the part and cnc finish them
12:43 AM rue_mohr: I asked how much shipping on the spool of wax was
12:43 AM rue_mohr: cause, $50 isn't actually unreasonable
12:44 AM zhanx: it needs to be a dual extruder
12:44 AM zhanx: pla for support and wax for casting
12:47 AM zhanx: screw it biting the bullet and ordering the motors for the wax printer
12:48 AM zhanx: and done
12:49 AM rue_mohr: hmm
12:50 AM zhanx: either way i make a 2nd printer or a wax printer
12:50 AM rue_mohr: 2nd printer for sure
12:50 AM rue_mohr: your too busy for 1 printer
12:50 AM zhanx: as are you
12:51 AM zhanx: least this time it will be easier to make
12:53 AM zhanx: rue_mohr, i ordered 5 motor steppers so i can make this a dual extruder
12:53 AM zhanx: wax on one if needed and support on the other
12:56 AM rue_mohr: I was looking into designing multimaterial parts,
12:56 AM rue_mohr: its sad
12:56 AM zhanx: its a pita it looks like
12:59 AM rue_mohr: mumptai_,
12:59 AM rue_mohr: Nov 04 16:58:2004: #robotics mumptai :been thinking about building quadrature decocders with them
12:59 AM rue_mohr: Nov 04 16:58:2004: #robotics rue_mohr :what kind of interface?
12:59 AM rue_mohr: Nov 04 16:58:2004: #robotics rue_mohr :serial I presume?
12:59 AM rue_mohr: Nov 04 16:58:2004: #robotics mumptai :a&b in
12:59 AM rue_mohr: Nov 04 16:58:2004: #robotics mumptai :clk & dir out
12:59 AM rue_mohr: did you ever get to that?
01:01 AM zhanx: 14 years later
01:02 AM rue_mohr: looking at things to clear off my webspace there
01:02 AM rue_mohr: there is the *orgional* log file
01:03 AM zhanx: crazy that mumptai_ is still here
01:03 AM rue_mohr: *blink*
01:03 AM rue_mohr: so is tom and rue
01:04 AM zhanx: not the same
01:04 AM * rue_mohr looks sideways at zhanx
01:06 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/forceFeedbackServo/slide.htm
01:06 AM rue_mohr: I used the cnc to trim the cams off the vcr gears
01:06 AM zhanx: 2/3rds of the channel has never talked
01:06 AM rue_mohr: }:] well look what happened the last time I tried to fix that
01:07 AM zhanx: tom got mad
01:07 AM rue_mohr: so did about 21 others
01:07 AM rue_mohr: some of them were just sheep tho
01:08 AM rue_mohr: what do you think of da force servos?
01:08 AM zhanx: i like
01:08 AM zhanx: also i want a lathe now :D
01:09 AM rue_mohr: :)
01:09 AM rue_mohr: so, how do we get our stuff making money for us?
01:10 AM zhanx: you keep adding thing to stuff i want, i can't help there
01:11 AM zhanx: ok second printer, casting, lathe
01:11 AM zhanx: cnc fits in there somewhere
01:11 AM rue_mohr: haha, I'm slightly ahead and from my vantage I'm not gonna live long enough
01:12 AM zhanx: least i am build my lab now
01:15 AM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/slide.htm
01:15 AM rue_mohr: I have not successfully photojournaled a whole build yet
01:31 AM rue_mohr: so then, how do I split the force feedback servo into two controllers
01:32 AM rue_mohr: if each side does the same calc, the sign will be different on each end
01:32 AM rue_mohr: which should just result in the opposite motor polarity
01:32 AM rue_mohr: we need to drag another mind in on this
01:32 AM rue_mohr: aren't I good enough?
01:33 AM rue_mohr: I think more is better
01:33 AM rue_mohr: where do we find them?
01:33 AM rue_mohr: well, the whole idea was to stay put long enough for them to find us
01:33 AM rue_mohr: yea, you gave up on that last year didn't you?
01:34 AM rue_mohr: hahah we could 3d print meccano
01:34 AM rue_mohr: stay with me here
01:34 AM rue_mohr: right, sorry
01:38 AM rue_mohr: ok, well, if their as obscure as us and furrywolf, this wont be easy
01:38 AM rue_mohr: admit it, if tom and zhanx wheren't here, you could never find them
01:38 AM rue_mohr: ok, so were establishing a bad track record...
01:38 AM rue_mohr: think on this
01:38 AM rue_mohr: profile yourself, and search for that
01:38 AM rue_mohr: I suppose after 14 years we need to give up on plan A then eh?
01:38 AM rue_mohr: yep, flip the switch, go active
03:26 AM BitEvil is now known as SpeedEvil
04:06 AM rue_mohr: http://roboreprap.com/robotics/ircstats/electronics.html
04:06 AM rue_mohr: :)
04:26 AM veverak: deshipu: https://www.robotshop.com/community/forum/t/t08a2-hexapod-tank-from-ghost-in-the-shell/7266
04:26 AM veverak: !!! :)
04:29 AM weyland|yutani: nice
04:54 AM deshipu: veverak: that's a couple years old, but very nice
07:03 AM logicmoo is now known as dmiles
04:02 PM rue_mohr: took more than 1300 pics this year
04:10 PM Tom_L: that's a couple
04:11 PM rue_mohr: my goal is 1/day min.
04:11 PM rue_mohr: ~average~
04:11 PM Tom_L: you exceeded your goal this year
04:14 PM rue_mohr: ~
04:14 PM rue_mohr: its better to take 1 pic/day then to take 365 in one
04:15 PM rue_mohr: things in the background you didn't even think of keeping track of
04:16 PM rue_mohr: I'm gonna have to get outa my pajamas, I need to go buy milk
04:18 PM rue_mohr: did you see the gearbox I did last night?
04:18 PM rue_mohr: used the cnc for most of it, came out nicely
04:36 PM rue_mohr: nobody anywhere is saying anything
04:36 PM rue_mohr: did the CIA get to them?
04:44 PM zhanx: must have
04:45 PM zhanx: i am helping someone get their ramps setup for a printer
04:45 PM rue_mohr: huh, I just found someone else who is a "recreational technologist"
04:45 PM rue_mohr: ok
04:45 PM zhanx: sweet the more the merrier
04:46 PM rue_mohr: yea, One is the loneliest number.
04:46 PM rue_mohr: ai teddybears on the shelf?
04:46 PM rue_mohr: that would be creepy dude
04:47 PM rue_mohr: yes, but.
04:47 PM zhanx: so i ordered windows blind chain for the 2d plotter
04:47 PM rue_mohr: no, I dont think it would make it past creepy
04:47 PM rue_mohr: window blind chain?
04:47 PM rue_mohr: the molded ball and chain stuff?
04:48 PM rue_mohr: didn't want to just use tub chain?
04:48 PM zhanx: it was cheaper
04:48 PM rue_mohr: mhm
04:48 PM rue_mohr: did you design a sprocket yet?
04:48 PM zhanx: not yet, but it gets here monday
04:48 PM zhanx: was going to do it then
04:49 PM rue_mohr: ....today IS monday
04:49 PM zhanx: next monday
04:49 PM rue_mohr: ah
04:50 PM rue_mohr: well, I'v found 4 people to reech out to on the internet, see if I get replies
04:50 PM rue_mohr: need to go get milk
04:51 PM zhanx: i told the wife i was making another printer, she asked why 1 and not 4
04:52 PM rue_mohr: the printers *just* fit in a rack
04:52 PM rue_mohr: so, if you find a rack on its way out, snag it
04:52 PM rue_mohr: you can fit 3 printes on it
04:52 PM rue_mohr: when you fit a printer into a rack, you will go 8-| and realize you can use the rack AS the frame of the 3d printer
04:53 PM zhanx: nice
04:53 PM rue_mohr: between the rack and table, there aren't many parts needed
04:53 PM rue_mohr: then you will just get carried away making racks that are arrays of 3d printers
04:53 PM rue_mohr: cause if you use the rack as the frame of the 3d printer, you can prolly fit 4 per
04:53 PM zhanx: and never get anything done
04:54 PM rue_mohr: yes and no
04:54 PM rue_mohr: you show one of the kids how to print designed parts
04:54 PM rue_mohr: they can take care of the thingiverse requests directly
04:54 PM rue_mohr: whele you design parts you need
04:55 PM rue_mohr: how olds your kid?
04:55 PM rue_mohr: 3? I wans't keeping track
04:56 PM rue_mohr: I been following myself down while going to sleep
04:56 PM rue_mohr: but most of the intersting stuff happened in the morning
04:57 PM rue_mohr: well, analitically
04:57 PM rue_mohr: I realized that adventure is really important to being able to get up in the morning
04:58 PM rue_mohr: if you know what is going to happen, there isn't much fun to it
04:58 PM rue_mohr: you lost your audiance dude
04:58 PM rue_mohr: oh, milk?
04:58 PM rue_mohr: yea, I suppose
04:58 PM rue_mohr: do we need anything else?
04:59 PM rue_mohr: adventure
04:59 PM rue_mohr: hah
05:28 PM Tom_L: mmm rack mount printers
06:50 PM LuminaxHome is now known as Luminax
09:37 PM flav0r: WHATS UP DUDES ????
09:37 PM rue_mohr: house plan
09:37 PM rue_mohr: due in 4.5 hours
10:44 PM flav0r: dude i cant be bothered layign this thing out to test on a breadboard
10:44 PM flav0r: jsut gonna design it and make it !
