02:31 AM CaptHindsight: mini injection molding machine
02:31 AM laminae_: Saw that recently actually
02:31 AM laminae_: two pins though?
02:31 AM CaptHindsight: what reprappers could have worked on
02:31 AM laminae_: Even on a pretty forgiving draft i can't see many uses for that that aren't just pure mass production of cap or something similar
02:31 AM laminae_: Random segway, has anyone used lcnc for raster laser engraving?
02:31 AM CaptHindsight: yes
02:31 AM laminae_: I found a bunch of discussion with nothing definitive on the googles
02:33 AM laminae_: But if i am going to chuck over 4 grand into it i might as well put some effort in
02:33 AM CaptHindsight: https://www.youtube.com/watch?v=0eXu1hFaymI
02:33 AM CaptHindsight: Frankenlab CNC #19 - LASERs and M Codes
02:34 AM CaptHindsight: has afew videos on it all
02:34 AM laminae_: Thanks, watching
02:35 AM CaptHindsight: https://www.youtube.com/watch?v=A3iS1ba0Z2I
02:35 AM CaptHindsight: Frankenlab CNC #17 - Frickin LASER
02:36 AM CaptHindsight: https://www.fbo.gov/index?s=opportunity&mode=form&id=5fdb0522f0667e24e19274519b8ef011&tab=core&_cview=0
02:36 AM CaptHindsight: Microscale Bio-mimetic Robust Artificial Intelligence Networks (μBRAIN)
02:37 AM CaptHindsight: https://www.cnczone.com/forums/general-laser-engraving-cutting-machine-discussion/186700-cam-software-forum.html
02:37 AM CaptHindsight: also see http://www.scorchworks.com/index.html
02:41 AM laminae_: That second to las tone looks to be exactly what i was on the hunt for
02:41 AM laminae_: Thanks
02:41 AM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Rastering_With_A_Laser
02:42 AM laminae_: I did see that graster on the wiki but it doesn't play well with most of the configs i've found
02:42 AM laminae_: Grante di am only using a vm to test that
02:42 AM CaptHindsight: me use glavos and lasers
02:42 AM CaptHindsight: make cutter, engraver, SLS printer etc
02:43 AM * Wolf__ still wants to build a nice sized co2 laser
02:43 AM laminae_: So, i use a hse kern 150w laser at work a lot
02:43 AM CaptHindsight: me use laser and galvo to cure resin in sand to make mold for cvastings
02:43 AM laminae_: And i love it
02:44 AM Wolf__: right now I need to finish my janky looking plasma cutter
02:44 AM laminae_: I had a chance recently where i could have taken a job for 9k for not evnen a month of hobby work but i didn't have a machine to cut it
02:44 AM CaptHindsight: https://img.purch.com/w/640/aHR0cDovL3d3dy5saXZlc2NpZW5jZS5jb20vaW1hZ2VzL2kvMDAwLzA1NS83NTQvaTAyL3NlbGVjdGl2ZS1sYXNlci1zaW50ZXJpbmcuanBnPzEzNzY0Mjg4NjM=
02:44 AM laminae_: I've had a ton of smaller ones pass me by for the same thing
02:44 AM laminae_: CUtting tool foam
02:45 AM laminae_: Usually for (large) stanley vidmars
02:45 AM Wolf__: should be fun to see how good/bad this does https://i.imgur.com/buaZcnI.jpg lol
02:45 AM laminae_: YIKES
02:45 AM laminae_: Is that yours?
02:45 AM Wolf__: yup
02:45 AM CaptHindsight: this way SLS no use glavos, so slow and clunky https://www.youtube.com/watch?v=P7afUagBVZc
02:46 AM CaptHindsight: Wolf__: where do you eat your lunch? :)
02:46 AM laminae_: Kinda scary but best of luck. I'm surprised contamination isn't an issue on that sls
02:47 AM Wolf__: 1.5m x 1m frame plasma, target use is 1/4”, 1/2” and 3/4” plate so speed shouldn’t be a issue with the frame
02:48 AM laminae_: How are you controlling the pulsing?
02:49 AM Wolf__: mesa 7i96 + thcad, currently cheap 420oz steppers on it, was thinking clearpath at some point
02:49 AM laminae_: I mean on the cutter
02:49 AM laminae_: I'm thinking in tight radius corners or high detail you might get some blowout
02:50 AM Wolf__: not being build for high detail lol
02:50 AM Wolf__: https://i.imgur.com/PKS1kDE.jpg
02:50 AM laminae_: Fair enough
02:51 AM laminae_: If you're using leadscrews which i looks like you are, i wouldn't be concerned about the rest, i probably wouldn't do it in your living room though haha
02:51 AM Wolf__: haha yeah
02:51 AM laminae_: You guys have any recomended sources for legit hiwin rails?
02:53 AM CaptHindsight: hiwin has a discount store
02:53 AM CaptHindsight: with returns and overstock
02:55 AM Wolf__: max 6706mm/min on 8mm pitch T8 lead screw shouldn’t be too horrible I think
02:56 AM CaptHindsight: http://www.automation-overstock.com/index.asp
02:56 AM laminae_: Nice
02:57 AM CaptHindsight: http://www.automation4less.com/

02:59 AM CaptHindsight: http://www.automation4less.com/store/categories.asp?cat=115
03:00 AM laminae_: Have you ordered from them personally?
04:48 AM jthornton: morning
04:49 AM Deejay: hey
04:49 AM XXCoder: heys
05:02 AM Tom_L: morning
05:04 AM XXCoder: yo
05:31 AM Wolf__: morning
05:32 AM The_Ball: Is there a roadmap for 2.8 somewhere?
05:35 AM Wolf__: jthornton: gonna start the install process on the ITX box, when I was messing with the test install on my desktop (on SD card) got a fail building the deb - debuild: fatal error at line 1152: dpkg-buildpackage -rtfakeroot -us -uc -ui failed
05:36 AM jthornton: yea, testing that this morning... I think I have it all sorted out now
05:37 AM Wolf__: cool, also should the gitclone path be emc or linuxcnc?
06:03 AM jthornton: you can clone to any empty directory I like emc, it's the nist name
06:05 AM Wolf__: I did notice that the 7i96 setup thing expects linuxcnc as the directory =P
06:10 AM jthornton: and that's the reason you don't want to clone to linuxcnc because when you run linuxcnc it creates that directory
06:11 AM Wolf_ITX_: ahh ok
06:11 AM jthornton: you can go now just refresh the browser page with Ctrl Shift r
06:11 AM Wolf_ITX_: about to start the fresh install on this box now
06:16 AM jthornton: wow that pc I built linux mint 19 on has very low jitter of 6500 on the servo thread
06:16 AM jthornton: if you run into any glitches let me know...
06:16 AM XXCoder: dang
06:16 AM * jthornton installs debian 9 again and back to work on QtPyVCP docs
06:27 AM Wolf_2 is now known as Wolf_
06:28 AM jthornton: hmm if your going to have debian 9 and linux mint share a hard drive better install debian first lol as it does not have an option to install along with mint
06:29 AM Wolf_: naa doing a clean install
06:32 AM jthornton: no, just me I have a dual boot to work on qtpyvcp docs in debian and test other things in linuxmint lo
06:32 AM jthornton: l
06:33 AM Wolf_: ahh ok
06:43 AM * jthornton watches chicken TV for a while while debian installs
07:02 AM Wolf_ITX: ok, now the fun begins, jthornton whats the link again to the instructions please?
07:02 AM jthornton: http://gnipsel.com/linuxcnc/uspace/index.html
07:12 AM Wolf_ITX: damn the RT kernal directory is 17.8GB, no wonder it takes forever to build
07:55 AM `Wolf: well i did something wrong install attempt #2 lol
07:55 AM `Wolf is now known as Wolf_
08:57 AM Wolf_ITX: seems I did something wrong with the moving the kernal that I built on the other cpu, it causes a kernal panic on boot on this box =/
12:03 PM gloops: Heathrow airport runway 'is closed after a suspected drone sighting'
12:26 PM roycroft: so they've moved from gatwick to heathrow
12:26 PM roycroft: is that an upgrade?
12:27 PM Rab: In the sense of switching from one armpit to another.
12:27 PM SpeedEvil is now known as Guest97995
12:29 PM roycroft: i don't fly any more, because i refuse to participate in the kabuki security theatres that airports in the us became after 9/11
12:29 PM roycroft: so it's no concern of mine
12:29 PM roycroft: i'd hate to see folks injured/killed because of the drones, though
12:32 PM Rab: That is an honorable stance. I fly a lot for work, so it's out of my hands.
12:32 PM roycroft: it's been hard, but i've stuck with it
12:32 PM roycroft: i used to fly 3-4 times/year
12:33 PM roycroft: i last flew on 4 september, 2011
12:33 PM roycroft: fortunately, all the trainings i've needed to go to since then have been available in the bay area
12:33 PM roycroft: it's a 10 hour drive from here to sfo
12:33 PM roycroft: so i just drive when i need to do that stuff
12:34 PM roycroft: it probably would not take me much less time to fly, given all the bs that one has to go through at airports these days
12:34 PM roycroft: and i don't have to worry about renting a car when i get to my destination
12:35 PM Rab: Are you reimbursed for mileage?
12:35 PM roycroft: yes, but not totally
12:35 PM roycroft: i.e. i am reimbursed for the cost of a flight
12:35 PM roycroft: which more than covers fuel expense
12:35 PM roycroft: but normal reimburement is $0.55/mile
12:35 PM roycroft: i make decent money expensing mileage, normally
12:36 PM roycroft: the theory is that the reimbursement above fuel cost covers the cost of additional maintenance/wear/depreciation of the vehicle
12:36 PM roycroft: so i basically eat that expense as the cost of my choosing not to fly
12:36 PM roycroft: but immediate out of pocket expenses are covered
12:38 PM roycroft: at my normal reimbursement rate i'd get $616.00 in mileage to drive from here to sjc and back
12:38 PM roycroft: flights are usualy in the $400 range
12:38 PM Rab: Ever tried Amtrak?
12:38 PM roycroft: yes, i like amtrak a lot
12:38 PM roycroft: and when i go back east i take the train
12:39 PM roycroft: the bay area is close enough that i prefer to drive
12:39 PM roycroft: just because of the convenience of not having to deal with a rental and stuff
12:39 PM Rab: The Coast Starlight is a great route, although it's been a long time since I've done it.
12:39 PM roycroft: and there usually are not rental car lots adjoining amtrak stations, like there are at airports
12:39 PM roycroft: so it's more of a hassle getting a car when taking the train
12:40 PM Rab: Yeah, prob more expensive than a plane ticket too.
12:40 PM roycroft: the coast starlight and the empire builder are the two main trains i take
12:40 PM roycroft: but i don't go back east for business any more
12:41 PM roycroft: when folks ask me if i'll consult for them, i quote my standard rate, and then tell them that i charge an additional $1/hour for every mile i have to travel east of the rockies
12:41 PM roycroft: someone in carolina can't afford me :)
12:44 PM roycroft: what works for me probably doesn't work for most folks
12:44 PM roycroft: but i'm getting older, and i've always disliked travelling for work
12:44 PM roycroft: now i'm getting rather insistent about not doing it
12:55 PM fragalot: classic "off by one" mistake :'( bought the wrong DC jack for my laptop & got the wrong one
12:55 PM fragalot: blimmin €17 down the drain
01:01 PM gloops: exchange it
01:23 PM BitEvil is now known as SpeedEvil
01:23 PM elmo40: fragalot, how is that possible? did you not specify make/model of laptop?
01:26 PM fragalot: elmo40: missed a character when I looked it up :P
01:27 PM fragalot: the DC jack part is correct, but the little connector to the motherboard isn't
01:27 PM fragalot: i'm sure I could make it work if I wanted to
01:29 PM elmo40: litle bit of solder and wire ;-)
01:32 PM elmo40: roycroft, travelling isn't cheap anymore! It sure as hell isn't me paying for it. Customer pays everything.
01:32 PM elmo40: I simply charge by the mile, both ways. then normal hourly rate when I get there.
01:37 PM jthornton: I charge normal hourly rate from the time I leave my house until I leave the customer so it works out 1/2 my rate for travel
01:41 PM fragalot: helps if you make sure your rate is 10% higher first
01:41 PM fragalot: :D
01:55 PM gloops: Germany in technical recession
02:11 PM fragalot: at some point the goal of growth needs to be revisited anyway
02:11 PM fragalot: it's impossible for everyone everywhere to have continuous positive growth... things must come from somewhere.
02:12 PM andypugh: Indeed, we live on a finite planet.
02:14 PM pcw_home: Yeah, the philosophy of a cancer tumor is continuous growth
02:15 PM fragalot: back to the days where growth was impossible. :P
02:15 PM fragalot: more people? needs more resources, which need more people to produce
02:15 PM fragalot: a perfect balance
02:26 PM gloops: the mayans had a good solution
04:07 PM The_Ball: Do you guys setup a sim version of your machine?
04:07 PM CaptHindsight: some do
04:08 PM CaptHindsight: there are sims for common arrangements
04:08 PM Deejay: gn8
04:10 PM The_Ball: Yes I've seen many of the bundled ones, thinking of making one to play with while I'm not in the shop
06:39 PM elmo40: Germany is weird. They are not renewing any nuclear power plants and going all 'renewable'.
06:40 PM elmo40: yet it is proven that wind/solar/hydro electric is not enough to power their country... solution? buy from other countries and pay carbon tax on their coal plants >_<
06:48 PM Jymmm: haha
06:59 PM CaptHindsight: elmo40: große riesenbatterien
06:59 PM CaptHindsight: big giant batteries
07:10 PM roycroft: elmo40: that seems to me to be a short-term solution while they're augmenting the renewable energy infrastructure
07:10 PM roycroft: which makes more sense than to renew nuclear power plant licenses and then mothball them shortly thereafter
07:32 PM Jymmm: or jsut use safe nuclear instead
07:37 PM Jymmm: https://www.google.com/search?q=thorium+reactors
07:53 PM roycroft: i would actually trust the germans to regulate nuclear power plants decently
07:53 PM roycroft: i do not trust the usa or japan to do so
07:53 PM roycroft: i would *never* trust industry to self-regulate
07:54 PM roycroft: but the germans have decided that nuclear power is not in their future
07:57 PM ziper: does this channel have a bot?
07:57 PM ziper: .seen
08:00 PM ziper: I bought the three mills
08:01 PM ziper: and a 36 inch callipers
08:01 PM ziper: and a bunch of parallels
08:05 PM skunkworks: I love cnc.. http://electronicsam.com/images/greenmachine/20190104_210312.jpg
08:37 PM Rab: skunkworks, did you make that?
09:55 PM CaptHindsight: https://imgur.com/gallery/mHV4okP
10:24 PM ziper: CaptHindsight, nice
11:00 PM Wolf_: no pics ziper?
