12:00 AM LeelooMinai: lol at one comment there: "Strange, but when you speak it sounds as if either you have a gun to your head and are very nervous or are in between crying fits going through a nasty divorce."
12:02 AM XXCoder: saw that, since I never heard anyone speak I cannot make an comprasion,.
12:05 AM LeelooMinai: XXCoder: Are there applications that you can use that would do speech to text to anything you are listening to on PC in real time?
12:06 AM XXCoder: not that I know of
12:06 AM LeelooMinai: Hmm, weird... I would think that should be a thing nowadays.
12:06 AM XXCoder: speech to text is very hard
12:06 AM XXCoder: micosoft did it I think
12:07 AM XXCoder: reconizion was better than human average
12:08 AM LeelooMinai: Well, hard not hard... I don't know. I mean I can imagine some self-learning neural network or who knows what system would do well. I read that google even has specialized ICs for this kind of stuff by now.
12:09 AM LeelooMinai: If you throw at it all the videos that already have captions, it could probably get good fast.
12:10 AM LeelooMinai: XXCoder: I see in 2015 5h3y had this: https://techcrunch.com/2015/01/14/amaaaaaazing/
12:10 AM LeelooMinai: 5xxx = they
12:11 AM XXCoder: hmm will try that
12:11 AM LeelooMinai: XXCoder: ...
12:12 AM XXCoder: sadlky my pc has no audio output lol but will test on tv later
12:12 AM XXCoder: or my tablet
12:12 AM LeelooMinai: XXCoder: Come on, that's weird...
12:12 AM XXCoder: why is it weird
12:13 AM LeelooMinai: XXCoder: Well, I would think that you know all there is about all existing technology like that...
12:13 AM XXCoder: looks like I installed it before. I guess I forgot
12:15 AM LeelooMinai: Also, doesn't google put every upload through some automatic caption process?
12:15 AM LeelooMinai: Er, youtube
12:15 AM XXCoder: not always
12:15 AM XXCoder: or user opted out of that
12:16 AM XXCoder: sometimes its a mystery - same user robrenz oped out of in one video and most videos autocaptions exist
01:20 AM XXCoder: LeelooMinai: man
01:20 AM XXCoder: the end result looks like it was always been
02:19 AM LeelooMinai: lol: https://en.wikipedia.org/wiki/The_Metric_Marvels
02:21 AM Deejay: moin
02:31 AM XXCoder: LeelooMinai: very reconizable style
02:31 AM XXCoder: schoolhouse rock of course
02:34 AM LeelooMinai: I find it funny, because it's clear now to me that it was futile:)
03:30 AM IchGucksLive: hi from late morning germany
03:30 AM XXCoder: yo
03:38 AM XXCoder: hah. https://youtu.be/OQOgRDztODM
03:40 AM pink_vampire: what is the recommended feed and speed for drill 2mm in aluminum 1000 rpm?
03:41 AM pink_vampire: IchGucksLive: XXCoder?
03:41 AM pink_vampire: how do I calculate it?
03:41 AM XXCoder: thats my worse area, I dont know
03:41 AM XXCoder: from what i understand you choose what is best "bite" amount like .01mm then calculate rest from it
03:42 AM XXCoder: some websites has ideal amounts for materials
03:42 AM IchGucksLive: pink_vampire: http://www.bünting.com/html/drehzahltabelle.htm
03:42 AM XXCoder: IchGucksLive: website dont exist
03:42 AM pink_vampire: it send me to http://www.xn--b14nting-rza5441f.com/html/drehzahltabelle.htm
03:43 AM XXCoder: or maybe its my irc client that dont work with urls with unicode
03:43 AM pink_vampire: and yeah.. not found
03:43 AM XXCoder: direct copy paste worked
03:43 AM IchGucksLive: thats maybe as the US denighs the ü
03:43 AM IchGucksLive: Ü
03:43 AM IchGucksLive: depends on language installed
03:44 AM XXCoder: web browser works with it. its irc client that didnt
03:44 AM IchGucksLive: there is a list down scroll
03:45 AM IchGucksLive: you can simply make a Exel sheet
03:46 AM IchGucksLive: and calculate like the webside
03:46 AM IchGucksLive: then print folie and hang it in your shop
03:46 AM XXCoder: http://www.custompartnet.com/calculator/drilling-speed-and-feed
03:48 AM IchGucksLive: pink_vampire: you got it
03:49 AM IchGucksLive: formola woudt be "n = vc / d x pi"
03:49 AM IchGucksLive: and the F is vf = n * z * fz
03:50 AM XXCoder: eclipse https://apod.nasa.gov/apod/astropix.html
03:50 AM IchGucksLive: XXCoder: thats the best side
03:50 AM IchGucksLive: but even better when seeing it live
03:50 AM XXCoder: yeah too bad I wont be able to see it
03:50 AM pink_vampire: so.. 1000 rpm, 0.0040 feed per revolution. plunge feed rate 4mm/min
03:51 AM pink_vampire: for 2mm drill bit, in aluminum
03:51 AM IchGucksLive: 0.04
03:51 AM pink_vampire: 0.04 per rev???
03:51 AM IchGucksLive: per theeth fz
03:51 AM IchGucksLive: with z = 2
03:52 AM IchGucksLive: 1000*2*0,04
03:52 AM archivist_herron: peck in deep holes
03:52 AM IchGucksLive: arvist is right on G83
03:53 AM pink_vampire: what is the depth for the peck?
03:53 AM pink_vampire: it is 11mm deep
03:53 AM IchGucksLive: 2.5mm
03:54 AM Loetmichel: pink_vampire: 1000 rpm with a 2mm drill bit?
03:54 AM Loetmichel: didnt you forgot a zero there?
03:54 AM pink_vampire: no
03:54 AM pink_vampire: my max speed is 1,000
03:54 AM Loetmichel: ah, i see
03:54 AM Loetmichel: sorry then
04:22 AM pink_vampire: I drill 2mm instead of 1.6mm and them tap to 2mm!! ERRRRR
04:24 AM pink_vampire: I drill 2mm instead of 1.6mm and them tap to 2mm!! ERRRRR
04:24 AM pink_vampire: archivist_herron:
04:25 AM pink_vampire: Loetmichel: IchGucksLive XXCoder
04:25 AM pink_vampire: any idea?
04:25 AM XXCoder: it drilled down 2 mm then went up and peck-drilled to 2mm?
04:26 AM pink_vampire: nooo
04:26 AM IchGucksLive: pink_vampire: the G-code ?
04:26 AM pink_vampire: i used the wrong drill bit
04:26 AM IchGucksLive: BAD
04:27 AM pink_vampire: 2mm diameter instead of 1.6, and then tap the hole to 2mm screw.
04:28 AM XXCoder: doh
04:28 AM pink_vampire: i'm going to fill the hole with J-B weld
04:30 AM IchGucksLive: till later
04:30 AM XXCoder: good thing its fixable.
04:35 AM pink_vampire: after good cleaning with acetone I'm going to heat up the part to make sure there is no oil and other issues in the hole. and then let it cool down, and fill it with j-b weld
04:41 AM archivist_herron: drill over size, rivet in same metal file flat, then re drill
04:41 AM Loetmichel: tap it 2,5mm
04:41 AM Loetmichel: @ pink_vampire
04:42 AM pink_vampire: no room
04:42 AM Loetmichel: really?
04:42 AM Loetmichel: so close to the corner?
04:42 AM Loetmichel: ouch
04:42 AM archivist_herron: jbweld will never hold a 2mm thread in a 2mm hole
04:42 AM Loetmichel: can you drill 3mm?
04:44 AM Loetmichel: if yes, i would drill 2.5mm, tap M3, screw in an M3 screw with some loctite to it, wait 2 hours, then cut the screw/file flat and drill again 1,6mm
04:45 AM Loetmichel: if its close enough to the corner that the M3 thread would peek out: spimply get a hammer an deform the 2mm hole until you can reliable cut an M2 thread in it
04:50 AM XXCoder: maybe stupid but maybe fill hole with jb weld, then screw m2 into it
04:50 AM XXCoder: clean surface
04:50 AM XXCoder: let it cure, then can screw m2 out
04:50 AM XXCoder: essentally pre-tapped. but jb weld I think is too weak?
04:51 AM archivist_herron: wont stick to ally that well
04:53 AM XXCoder: interesting
04:57 AM pcw_mesa_ is now known as pcw_mesa
04:57 AM Loetmichel: pink_vampire: what material? and how much force/temperature will be on that m2 screw when in use?
04:57 AM pink_vampire: aluminum 6061 t6
04:57 AM pink_vampire: just a cover
04:57 AM Loetmichel: could you get by with simply etching the inner surface of the drill hole and CA-glueing in an m2 grub screw in the hole and then use a nut on top ?
04:58 AM pink_vampire: noo
04:58 AM pink_vampire: it's a blind hole
04:59 AM Loetmichel: other possibility would be to buy some aluminium low temperature (= 450°C) solder, clean the paert, heat it up, fill the hole with solder and do the drill/tap again
04:59 AM pink_vampire: am alredy filled the hole with j-b weld and bake it a bit with the torch
04:59 AM Loetmichel: i meant a nut instead of a screw head
04:59 AM Loetmichel: so have the grub screw stick out like a engine head bolt
05:00 AM Loetmichel: that wont work
05:00 AM pink_vampire: it will work, but it also going to be UGLY
05:00 AM Loetmichel: jbweld will not adhere well enough to the hole walls to "survive" as only a spiral thread
05:01 AM Loetmichel: but you can of course try
05:01 AM Loetmichel: maybe it works against all odds ;)
05:01 AM pink_vampire: this is why I heat the aluminum before
05:01 AM Loetmichel: that has nothing to do with heating the aluminium
05:01 AM pink_vampire: and you must bake the j-b weld
05:02 AM Loetmichel: it has to do with the hole being to smooth to give the "sthread spiral" enough surface to "grab" to
05:02 AM Loetmichel: thats whya i ased if you could drill up to 3mmand screw in an (aluminium) screw
05:03 AM Loetmichel: and use its core to cut a new 3mm thread
05:03 AM Loetmichel: 2mm thrad
05:05 AM pink_vampire: I'm curious to see if the J-b weld will hold. and survive the tapping
05:07 AM archivist_herron: I would expect no
05:08 AM Loetmichel: same here
05:14 AM XXCoder: yeah
05:14 AM XXCoder: ohhhh https://hackaday.com/2017/06/15/need-to-hold-something-build-a-custom-vise/
05:14 AM XXCoder: vise
05:14 AM XXCoder: looks like some printed some milled
05:29 AM archivist_herron: erm plastic jaws are not new!
05:29 AM XXCoder: nah the vise is interesting though
05:30 AM XXCoder: never said plastic jaws is new either
05:31 AM archivist_herron: you didnt but there is implied "excited new" by that page
05:31 AM XXCoder: its new project to me
05:31 AM XXCoder: looked very interesting
05:31 AM XXCoder: I dont have mill to use one with but if I had I'd have tried
05:32 AM archivist_herron: soft, machinable and special jaws have existed for a rather long time
05:33 AM XXCoder: yeah and? im not too sure what your point is
05:35 AM archivist_herron: it is presented as a new idea
05:37 AM jthornton: morning
05:37 AM XXCoder: its presented as cool project
05:55 AM Loetmichel: hrhr, my mainPC here at home (win7) has 47:04:20:38 uptime... I think its high time to reboot it this evening when i am back home. Maybe the DynDNS client will work then again, also ;)
06:02 AM XXCoder: 03:31:38 up 52 days, 11:50, 2 users, load average: 1.01, 1.12, 1.19
06:02 AM archivist_herron: 11:31:58 up 389 days, 7:14, 6 users, load average: 0.42, 0.51, 0.48
06:02 AM Loetmichel: XXCoder: doesent count
06:03 AM Loetmichel: with *ux its easy ;)
06:03 AM * XXCoder bows to uptime god named archivist_herron
06:03 AM Loetmichel: same for archivist
06:03 AM jthornton: how do you see the uptime?
06:03 AM XXCoder: heh my windows xp record was 200 days something
06:03 AM archivist_herron: probably a mains lead safety check when it was last rebooted
06:04 AM XXCoder: jthornton: linux command uptime. cant remember on windows
06:04 AM jthornton: 05:33:51 up 3 days, 23:01, 2 users, load average: 3.09, 2.77, 2.31
06:05 AM XXCoder: I remember this one about 10 years uptime
06:05 AM XXCoder: it finally had some issue, and they couldnt find the computer
06:05 AM jthornton: we lose power often out in the woods
06:05 AM XXCoder: as it turns out it was left so long change was changed and it was walled in
06:05 AM XXCoder: *room was changed
06:06 AM XXCoder: unix os what a surpise eh
06:07 AM Loetmichel: XXCoder: the one they drywalled in at the university?
06:08 AM XXCoder: think so, forgot details been a while
06:22 AM XXCoder: https://factordaily.com/iisc-bangalore-drones-seeds-forests-karnataka/ pretty cool
06:22 AM XXCoder: 10k sq ft in a week or so. pretty quick
06:42 AM Tom_itx: 06:42:05 up 174 days, 17:45, 1 user, load average: 0.15, 0.05, 0.06
06:43 AM Tom_itx: updated to debian8 then
06:47 AM XXCoder: I had blackout 52 days ago unfortunately
06:55 AM Loetmichel: Uptime 388 days 3 hours 40 minutes <-my server is up a little longer
06:55 AM Loetmichel: the machine above is my home (gaming) PC
06:58 AM XXCoder: nice!
07:03 AM pink_vampire: I power off my computer when it not in use.
07:04 AM Loetmichel: pink_vampire: i use said gaming/main home PC as a IRC-BNC
07:04 AM Loetmichel: (among other things)
07:04 AM archivist_herron: Im still winning here at 389 days :)
07:04 AM Loetmichel: I am sitting at work at the moment, typing here via VNC
07:04 AM Loetmichel: thats why the home PC is running 24/s
07:04 AM XXCoder: I like this necktie standard. http://1.media.collegehumor.cvcdn.com/45/15/8fa6fe48bcb44d71b71e3fd8f61a2c49.jpg
07:05 AM pink_vampire: O_o
07:06 AM XXCoder: heh
07:38 AM MrSunshine: hmm is it possible to send gcode files by remote to linuxcnc ?
07:39 AM XXCoder: sure various kinds of file sharing stuff
07:41 AM MrSunshine: i want to be able to send a file from my computer to the computer on the router .. without having to save it somewhere etc
07:43 AM MrSunshine: i guess i could write a small client to receive tcp data and save it then use axis-remote to load it from that script
07:48 AM Loetmichel: MrSunshine: i even use the CNC mill completely remote
07:49 AM Loetmichel: its a normal linux, so all the usual File protocols are there, be it Samba or NFS or even FTP and the likes
07:49 AM MrSunshine: Loetmichel: i want the gui to be on the machines computer but i want to be able to easily send the gcode files to the control computer .. atm its a real hazzle with usb memories or some kind of network bound filesystem that works crap :P
07:49 AM Loetmichel: thats not the fault of linuxCNC usually
07:49 AM sync: use scp :P
07:50 AM Loetmichel: i have a few (windows) systems here that can see the samba shares of the CNC-mill... and a few that doesent... all im the same network, all can see each other. NO idea why ;)
07:51 AM Loetmichel: ofcourse here also runs a VNC demon on the mill and a webcam tool
07:51 AM Loetmichel: (vlc)
07:52 AM Loetmichel: to do THAT fromk the OfficePc: https://www.youtube.com/watch?v=9u_ChO1AKYY
07:53 AM Todd_Z: I save all my machine files to a central network server (a NAS).
07:53 AM Todd_Z: and have that mounted as a dire on the Linuxcnc machine and run them right from the network.
07:54 AM Todd_Z: dire/dir
07:55 AM MrSunshine: Todd_Z: yeah this is what i was thinking of doing also but sadly do not have a harddrive to put in my router :P
07:56 AM Todd_Z: It could also be a shared directory on another computer (even a Windows machine).
07:57 AM Todd_Z: Networking is something Linux excells at.
08:00 AM Todd_Z: You can set up shared directories on your CNC machine and save them to it remotely as well.
08:04 AM XXCoder: sync: this scp? http://www.scp-wiki.net/scp-633
08:16 AM pink_vampire: Loetmichel: archivist XXCoder and other, - the j-b weld works amazing!!! and save the hole!!
08:16 AM XXCoder: nice
08:16 AM XXCoder: thankfully that spot dont get much stress eh
08:16 AM Loetmichel: here's hoping that it stays that way
08:16 AM pink_vampire: yeah.. it is just for a cover.
08:17 AM pink_vampire: it is mostly cosmetic cover.. so almost zero load
08:22 AM XXCoder: now to work hard on turning time to relaxation. laters
09:09 AM gcardinal: Loetmichel very cool !
09:46 AM Loetmichel: gcardinal: just lazy ;)
09:47 AM Loetmichel: (and its quieter)
09:49 AM gcardinal: Loetmichel jupp looking for same setup. also I would like to store recording of each job - so I can analyze how it went in slo mo
09:49 AM gcardinal: I often find my self adjusting settings way to much and on the fly.
10:17 AM JT-Shop: odd I just installed Linux Mint 18.1 with LinuxCNC uspace master and ran the latency test and got 5,xxx,xxx but no problems running Axis sim...
10:28 AM Roguish: JT-Shop: hey, what's the status of Jessie and a CD image?
10:29 AM Roguish: or even Stretch, since it's out now. Ubuntu seems out, and Wheezy is getting long in the tooth.
10:30 AM JT-Shop: dunno, that's above my pay scale
10:32 AM Roguish: oh come on. you're Mr. Document !
10:35 AM Roguish: JT-Shop: on another note... ever run Python on windows? with Anaconda?
10:39 AM JT-Shop: I think I wrote a python program a long time ago for windoze but forget what it was now
10:40 AM Roguish: i have a test fixture with Anaheim Automation stepper motors/drives, and a data acquisition system.
10:41 AM Roguish: the client wrote a python script to run the motors and take data.
10:42 AM Roguish: the DAC does not have a Linux API thing. doh!!!
10:52 AM JT-Shop: oh fun
10:52 AM JT-Shop: looks like Linux Mint 18.1 with the kernel I built is not going to work, I'm getting sserial errors
10:56 AM JT-Shop: maybe I picked the wrong kernel klink
11:13 AM JT-Shop: http://gnipsel.com/images/emc/john-19Jun2017-76.png
11:13 AM JT-Shop: http://gnipsel.com/images/emc/john-19Jun2017-386.png
11:13 AM JT-Shop: first one is mint 18.1
11:21 AM phipli: and home
11:26 AM pink_vampire: hi
11:40 AM JT-Shop: hola
11:44 AM pink_vampire: the part is finished!
11:49 AM pink_vampire: took me about a day to finish the part
11:52 AM IchGucksLive: hi from germany
11:52 AM pink_vampire: it was 434 grams of aluminum block' and now is is just 73 grams! 83.1% chips!
11:52 AM pink_vampire: hi IchGucksLive
11:53 AM JT-Shop: chips ahoy
11:55 AM pink_vampire: I'm going to clean it
11:55 AM pink_vampire: and take some pictures!
11:57 AM howto: hi...i installed a bunch of libraries from synaptic and solved the pangocairo issue now it says that cant send mdi command while not homed...how to do that archivist?
11:58 AM howto: ooh and latemcy seems way higher than 25 mircoseconds...where do i enter the numbers in linuxcnc ?
11:58 AM howto: on a core i7 precision m6600
11:59 AM howto: i do not even need to run glxgears to get very high numbers
12:01 PM howto: archivist ...how to home my machine in linuxcnc?
12:02 PM pink_vampire: home
12:03 PM howto: how do you enter comand pink-vampire?
12:03 PM howto: pink_vampire
12:03 PM IchGucksLive: howto: use a simulation mashine or do you got a real mashine on it
12:03 PM pink_vampire: click on the mdi tab
12:03 PM howto: yep real machine...cooltool basic 540
12:04 PM howto: and i want to see those steppers spin
12:04 PM IchGucksLive: are there Hoiming Reference switches
12:04 PM FAalbers: pink_vampire, You are CNC'ing ?
12:04 PM pink_vampire: and then you will get an option to type a gcode command
12:04 PM pink_vampire: yes, I just finished an aluminum part
12:05 PM IchGucksLive: howto: it seams that the configuration is wrong do you got it done by stepconfwizard
12:05 PM FAalbers: Oh God ! Sorry . I thought I was in the Drones channel. My bad ! Of yourse everyone is CNC'ing ! :)
12:05 PM IchGucksLive: howto: double click on my name
12:05 PM pink_vampire: Drones???
12:06 PM FAalbers: Yeah , wrong channels :)
12:06 PM pink_vampire: I'm invited?
12:06 PM pink_vampire: FAalbers:
12:07 PM FAalbers: pink_vampire, Sure , just join #multirotors
12:24 PM pink_vampire: http://i.imgur.com/TFDVtCo.png
12:24 PM pink_vampire: http://i.imgur.com/AYSTUo7.png
12:24 PM pink_vampire: http://i.imgur.com/sPqfEFq.png
12:25 PM pink_vampire: IchGucksLive: archivist_herron XXCoder FAalbers howto
12:25 PM IchGucksLive: cool
12:25 PM pink_vampire: this is the part that I made
12:25 PM IchGucksLive: is this the 1.6mm hole
12:26 PM pink_vampire: correct
12:26 PM pink_vampire: M2 screws
01:08 PM Wolf_: neat looking part, what is it for though?
01:17 PM MrSunshine: anyone good at math ? over 500mm ive got 0.45mm error in squareness, how many degrees is this and on a linear move .. how much would the error be on that axis? =)
01:20 PM Roguish: MrSunshine: arcsin(.45/500) = .05156 degrees.
01:20 PM MrSunshine: oh ok =)
01:20 PM pcw_mesa: lazy says sin(x) ~=x for small x
01:20 PM Roguish: that's true also.
01:21 PM Roguish: pcw_mesa: so, how's the new place?
01:22 PM pcw_mesa: Nice, a bit cramped because 1/2 the space is occupied by a tenant
01:23 PM pcw_mesa: about 6 blocks from our home, that's the best part
01:24 PM CaptHindsight: pcw_mesa: have you fully unpacked yet? :)
01:24 PM pcw_mesa: no...
01:24 PM CaptHindsight: same here
01:25 PM pcw_mesa: We have a lot of seldom used test fixtures and such like that will probably remain in boxes until needed
01:26 PM CaptHindsight: did you get to keep your museum pieces?
01:26 PM CaptHindsight: old computers
01:26 PM pcw_mesa: Nope, all gone
01:27 PM pcw_mesa: (well except for a Friden 132 calculator)
01:28 PM CaptHindsight: I left a pallet full of circa 1998 PC's at the old place
01:28 PM pcw_mesa: I still have some Xerox Daybreak machines under the house...
01:29 PM CaptHindsight: hardly used 300-400mhz pc's with 10GB HD's, I'm not really sure how you are supposed to dispose of them now
01:29 PM pcw_mesa: classic computer list member took 3 car loads of DEC and HP stuff
01:29 PM CaptHindsight: pay $50ea for recycling?
01:30 PM CaptHindsight: at least you found a good home for them
01:31 PM pcw_mesa: yeah old PCs of that vintage are at the minimum (negative) value
01:31 PM pcw_mesa: Do you have a E-waste colllection day? we have those here occasionally
01:32 PM CaptHindsight: I just checked and Goodwill will take them (if you drop off)
01:34 PM CaptHindsight: they probably sell them for $5
01:56 PM kyle____: Loetmichel_, I don't have enough disposable income for that :P
01:56 PM kyle____: maybe just a gun lover
02:01 PM MrSunshine: hmm anyone else hadproblems with a router making conical holes ?
02:01 PM MrSunshine: dont get why .. measured squareness up and down to be about 0.02mm .. spindle is trammed to 0.05mm/180mm and no backlash in the screws that i can find
02:02 PM sync: put a ballbar in and measure your concentricity
02:03 PM MrSunshine: well i do not have one of those :P
02:06 PM CaptHindsight: i had an end mill last week that lost several thousandths since it was softer than the hardened part being cut
02:10 PM Loetmichel_: kyle___: luckily i am in no danger of going there... i live in germany... the closest to a gun nut i have in the "neighborhood" is joerg sprave :-)
02:10 PM Loetmichel_: MrSunshine: flexing of z-axis?
02:10 PM Loetmichel_: try with less forces involved
02:10 PM kyle____: is that the slingshot guy?
02:10 PM Loetmichel_: kyle___: yes
02:11 PM kyle____: haha he's great
02:11 PM kyle____: he's an honorary american in my opinion
02:11 PM Loetmichel_: i actually met him once in a mall
02:11 PM Loetmichel_: he only lives 30 miles or so from here
02:11 PM kyle____: nice, pretty close then
02:13 PM Loetmichel_: we actually have ONE thing in common: the will and ability to improvise
02:13 PM Loetmichel_: ... anything ,)
02:15 PM kyle____: hey me too
02:15 PM kyle____: maybe it's my german heritage
02:15 PM Loetmichel_: hmm
02:15 PM Loetmichel_: how many generations back?
02:15 PM kyle____: my ancestors came over in the 1850s
02:15 PM kyle____: so pretty far back now
02:16 PM Loetmichel_: if i would ever move to the US i would probably go offgrid...
02:16 PM Loetmichel_: that would be fun
02:16 PM kyle____: can't say I'd blame you
02:16 PM Loetmichel_: sadly thats nearly impossible here in germany
02:16 PM kyle____: yeah, it's still very possible here
02:17 PM Loetmichel_: not comletely offgrid, i DO like me some internet :-)
02:17 PM Loetmichel_: but thats what sattelite or cell is for ;)
02:18 PM Loetmichel_: but the rest? yeah, i can totally see me building a nice litte 6 room cottage with attached workshop and garage
02:19 PM Loetmichel_: ... dig a well, get some solar and wind (or hydro if aviable) and go for it ;)
02:20 PM Loetmichel_: over here its pretty expensive to get land... and then you need a permit for every fart you make in the nature... building something outside a "residential building zone"? VERBOTEN...
02:36 PM kyle____: my impression of building code here is
02:36 PM kyle____: "do whatever you want but you'd better comply if you wanna sell that shit"
02:37 PM kyle____: ofc, it varies a lot depending on where you are
02:37 PM Loetmichel_: kyle___: over here in germany its more like: "if you dont want your building demolished AND pay fpor that: better follow the code to the dot.
02:37 PM kyle____: can't just go buy a lot in the middle of a city and build a lean-to farm
02:37 PM Loetmichel_: "
02:37 PM kyle____: yeah, makes some sense with how limited europe is on space
02:38 PM Loetmichel_: have you ever looked at germany from above?
02:38 PM kyle____: this concept seems to be a core struggle in american politics
02:38 PM Loetmichel_: what limited space?
02:38 PM kyle____: lol, well
02:38 PM kyle____: if you guys owned land like americans do, there'd be nothing left!
02:38 PM Loetmichel_: SOME of us do
02:38 PM Loetmichel_: not many though ;)
02:39 PM Loetmichel_: we are only 80 million tho, not 3000
02:39 PM kyle____: you're right, it does still look pretty empty
02:39 PM Loetmichel_: 300 million
02:40 PM kyle____: true, but you're only 137,983 sq mi and the US is 3.8 million!
02:40 PM Loetmichel_: funny thing is: there are a LOT of places where you step out the back door of a small skyscraper and cross the street and are suddenly in a 1000 acre wood...
02:40 PM kyle____: sounds nice
02:40 PM Loetmichel_: which is pretty nice when you are a kid ;)
02:40 PM kyle____: sounds like my hometown really
02:41 PM kyle____: lived in the suburbs but could still hear cows in the morning
02:41 PM kyle____: but where I live now is even closer to some cows, it's just that the noise of the city drowns them out...
02:42 PM MrSunshine: Loetmichel_: dont think so .. not that much on this machine ...
02:43 PM MrSunshine: Loetmichel_: https://scontent-arn2-1.xx.fbcdn.net/v/t1.0-9/19225767_10155502093698648_7271395169416247091_n.jpg?oh=ddf832a2bb1a055de4ce8697d2d91f1d&oe=59E23869

02:44 PM MrSunshine: if the link works
02:44 PM kyle____: nice place!
02:44 PM roycroft: i lived in the suburbs of chicago when i was young
02:44 PM roycroft: 50km from downtown chicago
02:44 PM Loetmichel_: MrSunshine: looks pretty sturdy
02:44 PM roycroft: at the very end of the commuter train line
02:44 PM roycroft: everyone i know was focused on the city
02:44 PM kyle____: https://www.google.com/maps/@38.9859107,-94.2570693,2026m/data=!3m1!1e3
02:44 PM roycroft: and getting there
02:44 PM kyle____: this is the general area where I grew up
02:45 PM kyle____: family still lives there so I won't pinpoint it :P
02:45 PM roycroft: i seemed to be the only person who was aware that there were corn fields 3 blocks from my house
02:46 PM kyle____: heh, everyone was well-aware that we had soy fields here
02:46 PM kyle____: they're right on the main road
02:46 PM Loetmichel_: kyle___: the village where i lived is 800 years old.
02:47 PM kyle____: 137 years here :P
02:47 PM kyle____: quite the difference
02:47 PM Loetmichel_: and the city center still is made of houses about that age.
02:47 PM kyle____: I think we have exactly two buildings from 1880 left
02:47 PM FinboySlick: 800 year old plumbing sucks though ;)
02:48 PM kyle____: one of them was going to be torn down, but the whole city came together and raised enough money to pick it up and move it somewhere else
02:48 PM kyle____: it's just a tiny train depot building
02:48 PM Loetmichel_: FinboySlick: modernized of course
02:48 PM Loetmichel_: but the church was from the 1400s
02:48 PM Loetmichel_: :-)
02:48 PM Loetmichel_: s/was/is
02:49 PM Loetmichel_: kyle___ pick up and move it? have fun trying that here
02:49 PM kyle____: haha, yeah, it wasn't very big at all
02:49 PM Loetmichel_: those old buildings are usually made of stones the size of a small bull ;)
02:50 PM kyle____: it's just a one-room building made of wood
02:50 PM Loetmichel_: s/are/here are
02:50 PM kyle____: I remember going inside it once and finding a pile of old railroad nails
02:50 PM kyle____: still have one somewhere
02:52 PM Loetmichel_: In my childhood i walked with my younger sister to the next farmer every moring before school (about 2 miles or so) and bought fresh (still cow warm) milk from him
02:53 PM Loetmichel_: fond memories we have sometimes ;)
02:56 PM Crom: MrSunshine: does that gantry have a third stepper at the back top?
03:14 PM MrSunshine: Crom: no just one side :/ need to figure something out
03:23 PM CaptHindsight: must be deal week, just found a 3ph 5hp compressor for $300
04:30 PM LeelooMinai_: There should be a bot on technical channels that automatically translates weird units, like hp, into world-wide ones:)
04:30 PM LeelooMinai_ is now known as LeelooMinai
04:30 PM kyle____: bah
04:30 PM kyle____: freedom units are all you need
04:31 PM XXCoder: yeah it gives me freedom to say 10 inches is 12 inches, or any oither number
04:31 PM XXCoder: ;)
04:32 PM XXCoder: also, so it was orginially called french units before that era when french fries become freedom fries? ;)
04:32 PM LeelooMinai: What pisses me of is that imperial units do not only stop at being weird in itself - you also have variations of each one. Like tons of kinds for ounce, etc.:/
04:33 PM LeelooMinai: Or mile - you have land mile, marine mile, etc.
04:33 PM XXCoder: just be glad you dont have more than one kind of imperial now
04:33 PM XXCoder: it used to be used on that country king
04:33 PM LeelooMinai: I bet horse power is also not unified.
04:33 PM XXCoder: foot being king's foot so on
04:33 PM LeelooMinai: Lol: mechanical horsepower and metric horsepower - lame.
04:34 PM XXCoder: Napleon being short person was due to french inperial having larger foot than inch than english of that era
04:34 PM XXCoder: he was really 5' 7" english units (which is bit above average then)
04:34 PM LeelooMinai: + electric horsepower, hydraulic horsepower and air hirsepower, boiler horsepower - what's wron with those people...
04:35 PM XXCoder: lol
04:35 PM XXCoder: well time to go work laters
04:36 PM DaViruz: don't forget the British Thermal Unit )
04:36 PM DaViruz: :)
04:37 PM DaViruz: usually expressed in BTU/h for power
04:37 PM LeelooMinai: Right, 5'7" is not really unusual - a bit small for a man I guess, but not ridiculous.
04:38 PM LeelooMinai: Yesterday I found that in 70s I think they made a cartoon for children in US with characters that had names from metric uints - like Meter Man, Litre-something, etc. hoping that this will help adopting metric units:)
04:39 PM LeelooMinai: I guess that did not help much.
04:41 PM LeelooMinai: I guess this map tells it all:( https://upload.wikimedia.org/wikipedia/commons/e/eb/SI-metrication-world.png
04:48 PM LeelooMinai: Heh, that guy that North Korea kept in prison because he took a poster from a wall died after they sent him kind of brain-dead back. Probably a lot of people will be angry and remember that in the future.
04:54 PM Deejay: gn8
04:55 PM MarkusBec: LeelooMinai: maybe not the smartest move from northkorea
04:56 PM LeelooMinai: Well, if he died there, it would not be a lot of better.
04:56 PM LeelooMinai: Should not have arrested him for stupid thing in the first place.
04:58 PM Roguish: Yeah, like stay the hell out of North Korea....
04:58 PM MarkusBec: he was not executed by a cannon i dont know what is better
04:59 PM LeelooMinai: Tuourists do all sorts of dumb things - that's kind of expected:)
04:59 PM MarkusBec: https://www.theguardian.com/world/2016/aug/30/north-korea-reportedly-executes-officials-anti-aircraft-gun-purge
05:00 PM LeelooMinai: lol, anti-aircraft... So what, they first pushed them from a cliff, then tried to shoot? :)
05:01 PM MarkusBec: i i dont think they need a coffin
05:01 PM LeelooMinai: Maybe they have them paper wings and said "if you manage to survive, you will be free"
05:01 PM LeelooMinai: gave*
05:01 PM MarkusBec: maybe a mop
05:01 PM LeelooMinai: Or an umbrella:)
05:02 PM LeelooMinai: Well, I guess I would still preffer to be shot by a gun like that, than be executed in US though...
05:04 PM LeelooMinai: You can end up being cooked by a faulty eletric chair, or tortured by not-quite-working poison while being paralized - that's much more brutal imo.
05:07 PM LeelooMinai: lol: Vatican Says Trump’s Anti-Science Policies Sending America “Back To The Past”
05:07 PM DaViruz: i've never been shot, but i imagine there are plenty of ways where that can go wrong as well
05:07 PM LeelooMinai: You know world got crazy if Vatican is more pro-science than US
05:08 PM LeelooMinai: DaViruz: Well, yes, but if you are shot by an anti-aircraft gun, it's unlikely you will suffer long:)
05:08 PM DaViruz: might as well just strap on some explosives then :)
05:09 PM LeelooMinai: Though it's not very practical probably - I bet they had to look for the pieces of the guy in a large area.
05:10 PM Roguish: Trump's a jack ass.
05:11 PM LeelooMinai: Imo the most humane way to kill someone would be dropping something like 10 ton weight from 10 meters, so one ends up a flat disc in 10ms:)
05:11 PM DaViruz: nuclear explosion at point blank!
05:12 PM LeelooMinai: Well, that's not practical:)
05:12 PM DaViruz: probably not very economic or practical though
05:12 PM DaViruz: but i suppose you could do it in batches
05:12 PM DaViruz: a nuke should be good for a few hundred
05:12 PM DaViruz: and they insist on testing the things from time to time anyway
05:13 PM LeelooMinai: I guess gillotinue is kind of ok too, but the brain is working probably for few seconds at least.
05:24 PM LeelooMinai: If someone is into guitar playing, pretty scary skills: https://www.youtube.com/watch?v=j2dmvOomei0&t=180s
05:25 PM phipli: guillotine might leave the head for a few seconds after removal
05:25 PM phipli: which is grim
05:25 PM phipli: someone did some tests during the french revolution
05:25 PM phipli: got someone to keep blinking as long as they could
05:25 PM phipli: SCIENCE!
05:25 PM LeelooMinai: What do you mean "leave"... It's not like it will evaporate:)
05:25 PM phipli: *leave the head alive
05:25 PM phipli: sorry
05:26 PM phipli: listening to something at the same time as typing = wordfail
05:26 PM LeelooMinai: A, right, yes, that's why my idea with large weight just squashing someone is probably more bullet proof, sans minor detail of not having body afterwards for a funeral:)
05:27 PM phipli: meh
05:27 PM phipli: might be a myth
05:27 PM phipli: (the blinking thing)
05:28 PM LeelooMinai: Well, obviously, you will lose consciousness pretty fast - I mean the blood pressure will be gone immediatelly.
05:29 PM LeelooMinai: So if there are some muscle movements, that will be just some "automatic" twitches or something like that if any.
05:30 PM phipli: I prefer to use the technique of not killing people
05:30 PM phipli: although they tend to grumble about it more
05:32 PM LeelooMinai: Right, I am not for a death penalty, just OCD made me consider of better ways to perform it:p
05:32 PM phipli: More fun to thing worse
05:33 PM phipli: overdose on something fun would probably be a better way to go
05:33 PM phipli: die happy
05:34 PM LeelooMinai: Hmm, read that Amazon bought some food company. Yes! One will be able to order everything online soon probably:)
05:34 PM LeelooMinai: Now they only need to finish that dron-delivery idea.
05:34 PM LeelooMinai: drone*
05:34 PM phipli: Whole foods or whatever they're called
05:35 PM LeelooMinai: Right
05:35 PM phipli: LeelooMinai: don't your supermarkets do home delivery?
05:35 PM phipli: we don't have a car
05:35 PM phipli: (technically we do, but it is off the road intentionally)
05:35 PM LeelooMinai: With food, only some.
05:36 PM LeelooMinai: They should have cameras on food like meat, etc. where you can click to choose which piece you have:)
05:36 PM phipli: sometimes they can be a bit shitty and give you things nearly at the sell-by date
05:36 PM phipli: but most of the time it is ok
05:37 PM LeelooMinai: Right, well, quality of food went down long time ago, especially in big markets - not sure if that can by fixed by now.
05:37 PM LeelooMinai: Probably will only get worse.
05:37 PM phipli: our food has got a bit better
05:37 PM phipli: bread is better than it was
05:37 PM LeelooMinai: phipli: Our = ?
05:38 PM phipli: UK
05:39 PM LeelooMinai: A, ok, here it depends on the place. My mom drives with sister to "european food" store, because in Walmart, etc. they sell things that are barely edible:)
05:40 PM LeelooMinai: Cannot make proper chees, bread, etc. there.
05:40 PM LeelooMinai: chhese*
05:40 PM LeelooMinai: And imported ones have crazy prices.
05:44 PM phipli: I hear that they struggle to get vegan / food for people with allergies in america
05:44 PM phipli: someone was saying "Whole Foods" was one of the few places
05:45 PM phipli: my knowledge of American stores is almost exclusively from TV though.
05:45 PM kyle____: whole foods is generally regarded as being absurdly overpriced
05:45 PM phipli: Did I see you say you're in Canada-land?
05:45 PM LeelooMinai: I don't really know that store - I am in Canada. In a in-betweeen worlds place:)
05:46 PM phipli: the UK/America/France place
05:46 PM kyle____: most grocery stores I've been to tend to have an aisle of vegan/allergy friendly food
05:47 PM kyle____: not so much in the bay area though
05:47 PM phipli: I'd guess your food is cheaper than ours, we're net importers
05:47 PM kyle____: the stores are too undersized for that
05:47 PM kyle____: yeah, back in the midwestern US it's a lot easier to find food
05:47 PM kyle____: much cheaper, tons of space for enormous stores
05:48 PM LeelooMinai: Well, I just wonder in general how it will work out. But makes sense that it can become "a thing" to buy groceries in some semi-atuomatic way. And if anyone can start a trend, it's Amazon. Heared that the CEO or whoever of Amazon is almost catching Bill Gates by now in terms of worth.
05:48 PM kyle____: jeff bezos, makes sense
05:48 PM LeelooMinai: No idea why people need that much money though:)
05:48 PM phipli: to build spaceships it seems
05:49 PM kyle____: $84.1b vs $89.3b
05:49 PM LeelooMinai: I mean, at some point it does not make any difference...
05:49 PM kyle____: he's well on his way to being the richest man in the world
05:49 PM phipli: anyhow
05:49 PM phipli: time to try and sleep
05:49 PM phipli: its been 32*C for most of the day
05:49 PM phipli: an humid
05:49 PM phipli: because it always is
05:50 PM kyle____: ah nice, he owns the washington post, one of the most slanted media outlets in modern times...
05:51 PM phipli: I don't like sleeping at the moment, because usually you wake up to find a load of people have died for some pointless reason, or our government has broken something
05:51 PM phipli: but anyway. I guess I need to
05:51 PM LeelooMinai: I noticed that the best place to get news nowadays is listening to some comady shows - weirdly they manage to compress everything into nice BS-less pieces of information, and happen to be funny as a "side-effect":p
05:52 PM LeelooMinai: comedy*
05:53 PM kyle____: be careful with those, they like to slant it too :P
05:53 PM kyle____: they all slant it
05:54 PM kyle____: there's pretty much no way to get unslanted news anymore unless you go to a primary source
05:54 PM LeelooMinai: If you choose carefuly and are vigilent, it's still tons of better than "news" ones.
05:54 PM kyle____: yeah; I just think of Colbert specifically, who seemingly practices mind control on his audience
05:56 PM LeelooMinai: Yesterday I watched, what it was, John Oliver - it was about coal mining and some guy that is on top of the chain there. It was pretty informative actually. Yes, kind of hysterical and funny, but tons of info there that kind of sheds a light on absurdity of this all.
05:56 PM Wolf_: not bad if you keep in mind that everyone has a hidden agenda to go along with their information output
05:56 PM kyle____: yeah
05:56 PM kyle____: it's easy to bend facts into your agenda too
05:56 PM kyle____: either through omission or by implying association where there isn't any
05:57 PM kyle____: I suppose I dislike political/current events comedy shows because I feel like they're trying to dumb me down and chew my food for me
05:57 PM LeelooMinai: Right, I saw Colbert too few times - pretty funny stuff.
05:58 PM kyle____: he is funny from time to time, but he also has outright told his audience they're supposed to dislike something instead of laughing at it
05:58 PM LeelooMinai: But they have easy time now - they don't even need to work much probably:)
05:58 PM kyle____: packaging it as comedy lets you get away with it, but the subconscious effect is still there
05:58 PM kyle____: and they know it
05:59 PM LeelooMinai: Sure, but I don't think they are near the level of corruptness of people on Fox News and places like that.
05:59 PM kyle____: I think they're about even myself, but don't worry, I'm not going to push it :P
06:00 PM kyle____: it's all about perspective anyway
06:00 PM LeelooMinai: I will always take someone with a sense of humour over a robot from Fox News - but that's another story:)
06:00 PM kyle____: meeting time, be back in a bit
06:01 PM Wolf_: Fox news like to rant, sometimes leave out info, some of the other just make shit up though
06:03 PM LeelooMinai: Well, some things I saw they do were at a level that was mind boggling - clearly twisting, misleading, selective, manipulative, etc.
06:06 PM JT-Shop: sweet I'm almost ready to start testing the external offsets branch on the plasma
06:07 PM LeelooMinai: The have some pretty despicable characters there, too. Real "pieces of work" very skilled at trolling people:/
06:07 PM LeelooMinai: Like that Tucker guy - holy cow:)
06:11 PM LeelooMinai: They always use the same techniques in their "interviews", and it's all so transparent - I am not sure why people do not care that it's all game, no content. I guess no one cares.
06:16 PM LeelooMinai: Hmm, I wonder if I can glue PVC to wood with something like construction adhesive.
06:16 PM MrBismuth is now known as MrBusiness
06:17 PM LeelooMinai: I have PVC cement, but not sure if that will work with wood.
06:18 PM Wolf_: pvc cement usually fuses the pvc by melting it so probably won’t work so well on wood
06:19 PM LeelooMinai: Right, that's my though. I also have a cement, well, just cement, that works after you use it on two surfaces, wait a bit for it to dry, and then cxonnecte both sides and it holds like crazy.
06:19 PM Wolf_: may have to rough the pvc up some
06:19 PM LeelooMinai: I don't know, maybe if I prepared wood a bit with primer, not sure.
06:21 PM LeelooMinai: "For bonding to wood, we recommend Liquid Nails Sub-Floor Adhesive or Heavy Duty Construction Adhesive."
06:21 PM LeelooMinai: Heh, I guess construction adhesive it is, as I have some.
06:22 PM LeelooMinai: That stuff is pretty strong too - I used it for stairs nosing.
06:22 PM Wolf_: yup, construction adhesive works pretty good
06:23 PM LeelooMinai: Not really sure what's in it:)
06:25 PM LeelooMinai: It's kind of like a sticky paste that sticks to everything, then hardens, but is still a bit flexible.
06:25 PM LeelooMinai: And I found out that if it dries on the skin, forget about being able to remove it:(
06:25 PM Wolf_: yeah, I’ve used a bunch of it in my house
06:25 PM LeelooMinai: Had to wait like 2 weeks untill it just fell off with the skin layers I guess:)
06:27 PM LeelooMinai: " Common ingredients include clay, cement, acrylic resin, polyurethane monomers, styrene-butadiene rubber, hexane and other nonpolar solvents, and various initiators and functional additives."
06:27 PM LeelooMinai: Right, whatever I guess - not really into chemistry much.
06:35 PM Tom_itx: i've a mfg that recomends using pvc solvent to bond pvc and wood
06:43 PM Tom_itx: PVC-E
06:52 PM roycroft: i've used gorilla glue for that in the past with good results
06:52 PM roycroft: it's a polyurethane adhesive
06:53 PM roycroft: if the pvc solvent doesn't work out you might try that

07:53 PM GeneW_: looking for recommendations for good company that supports ,steppers, servos, drivers in the size of nema 17-34 or so. We need to build a test environment with motion etc.
07:59 PM LeelooMinai_: GeneW_: automationdirect.com maybe?
08:00 PM LeelooMinai_: GeneW_: There's also ClearPath - it's an interesting choice nowedays.
08:01 PM LeelooMinai_: As it is stepper/servo with driver in one and they have nice software for them.
08:01 PM LeelooMinai_: They have much better capabilities for fast and precise motion than steppers.
08:01 PM GeneW_: Many thanks!
08:03 PM LeelooMinai_: They are US though - not China, but probably still good.
08:07 PM kyle____: http://hackaday.com/2016/06/01/mechaduino-closed-loop-stepper-servos-for-everyone/ has anyone tried this out?
08:08 PM LeelooMinai_: Seems like some kind of ghetto ClearPath:)
08:09 PM malcom2073_: As much as linuxcnc is a ghetto fanuc? :-P
08:09 PM Vitran: GRBL is the getto version of Linux CNC
08:10 PM LeelooMinai_: Well, it's a pcb on top of a stepper - it's not even nicely enclosed there.
08:10 PM * LeelooMinai_ looks for the encoder
08:11 PM LeelooMinai_ is now known as LeelooMinai
08:11 PM malcom2073_: iirc, it's on the back of the board
08:11 PM kyle____: yeah I actually got some samples of those encoders
08:12 PM kyle____: it's really just a tiny IC
08:12 PM malcom2073_: They glue a magnet to the end of the shaft, like a sin/cos encoder
08:12 PM LeelooMinai: I was just going to guess it's not a proper one...
08:12 PM malcom2073_: Nope, it's proper
08:12 PM kyle____: yeah they're surprisingly good
08:12 PM kyle____: lemme see if I can find the product listing
08:12 PM LeelooMinai: Well, it's not proper proper:)
08:12 PM malcom2073_: Erm
08:13 PM malcom2073_: If by proper proper, you mean.. no quadrature?
08:13 PM malcom2073_: not*
08:13 PM malcom2073_: There are a few different types of encoders
08:13 PM malcom2073_: they each have advantages and disadvantages
08:13 PM LeelooMinai: I mean it's probably some hall-effect cheap solution, instead of etched disk, etc. ones.
08:13 PM malcom2073_: I think you're just angry
08:14 PM LeelooMinai: ...
08:14 PM kyle____: http://ams.com/eng/Products/Magnetic-Position-Sensors/Angle-Position-On-Axis/AS5047D
08:14 PM LeelooMinai: I am angry? Why would I be angry? :)
08:14 PM malcom2073_: Good question.
08:14 PM malcom2073_: kyle____: Yeah! that kind
08:14 PM kyle____: yeah, I ordered a couple samples after reading this article
08:14 PM LeelooMinai: malcom2073_: I am definitelly not angry right now:p
08:14 PM malcom2073_: Oh cool, that one has quad output?
08:14 PM malcom2073_: Heh ok
08:14 PM kyle____: discovered it's... a tiny IC and not very useful to me, lol
08:15 PM malcom2073_: yeah TSSOP-14, though they make breadboard adapters for htem
08:15 PM kyle____: must be tiny
08:15 PM kyle____: jeez
08:15 PM LeelooMinai: TSSOP is monstrous
08:15 PM malcom2073_: Yeah they're pretty tiny adapter boards
08:15 PM malcom2073_: don't recall where I saw them
08:16 PM kyle____: that's a matter of perspective
08:16 PM malcom2073_: Actually, adafruit! https://www.adafruit.com/product/1210
08:16 PM kyle____: 5mm x 5mm package
08:16 PM LeelooMinai: Not that far away from prehistoric DIP:)
08:16 PM kyle____: I could probably handle soldering this with my new iron
08:16 PM kyle____: maybe I should grab a pack
08:16 PM LeelooMinai: Right, it's definitelly not 5 by 5
08:16 PM kyle____: nvm they're out of stock
08:17 PM malcom2073_: Doh
08:17 PM malcom2073_: https://www.digikey.com/products/en/prototyping-products/adapter-breakout-boards/643
08:17 PM malcom2073_: Cameacross that while searching for it
08:17 PM malcom2073_: Whole slew of adapters!
08:17 PM kyle____: excuse my derp
08:17 PM kyle____: it is 5mm on one axis though
08:17 PM LeelooMinai: Right, maybe on the short side, without leads:)
08:18 PM malcom2073_: Close enough that we got the idea, chill :)
08:18 PM kyle____: but yeah, this is a really, really cost effective alternative to an optical encoder
08:18 PM kyle____: ... if you can use it
08:18 PM malcom2073_: I wonder if you could stick the mechduino boards on the back of a motor to use as an encoder
08:19 PM LeelooMinai: malcom2073_: What is with that chill/angry/etc. - I am pretty chill and not angry...
08:20 PM kyle____: steppers are insanely versatile motors if only one can control them properly
08:20 PM malcom2073_: They are, I've got quite a few machines running with them. Someday I want to dive into servos
08:21 PM kyle____: I have this nasty habit of diving deeper and deeper into building a machine
08:21 PM kyle____: right now I'm working on a furnace to melt zamak to cast a monster gingery lathe
08:21 PM malcom2073_: Servos are a great way to rabbit hole yourself
08:21 PM malcom2073_: Ah nice! furnace is on my list
08:21 PM kyle____: so is casting :P
08:21 PM malcom2073_: way down on it
08:21 PM LeelooMinai: Right, well, they used that IC there for obvious reasons: much cheaper and smaller than proper encoder, so it's a compromise. Cannot expect it performing on par with higher quality ones.
08:22 PM kyle____: I started with a couple charcoal furnaces and now I'm working on a big 2 liter capable resistive furnace
08:22 PM kyle____: waiting on the controller to make its way from china
08:23 PM malcom2073_: Oh cool, decent sized
08:23 PM malcom2073_: how hot?
08:23 PM kyle____: doesn't need to be too hot, zamak melts at around 380 C
08:23 PM GeneW_: can you provide the url for ClearPath? I want to make sure I'm looking at the right stuff. Thanks!
08:23 PM LeelooMinai: Seems it's based on 4 hall sensors, and the rest is just processing data from them.
08:23 PM kyle____: the controller supposedly does 400 C, we'll see
08:24 PM kyle____: LeelooMinai, if you can get precise hall effect input then I don't see why a sin/cos based encoder wouldn't work well
08:24 PM kyle____: which seems to be the whole point of this thing
08:24 PM LeelooMinai: GeneW_: https://www.teknic.com/products/clearpath-brushless-dc-servo-motors/
08:24 PM malcom2073_: sin/cos encoders work qutie well
08:24 PM kyle____: 14 bits is quite a bit
08:25 PM kyle____: no I did not realize the irony in that statement before I sent it
08:25 PM LeelooMinai: That's kind of meaningless though - look inside the datasheet.
08:25 PM malcom2073_: lol
08:26 PM kyle____: 512 ppr isn't too awful
08:26 PM malcom2073_: That's on each channel of a quad fwiw
08:26 PM kyle____: and it is apparently within 0.08 degrees at 7000rpm
08:26 PM malcom2073_: so 2048 quad steps per rev
08:26 PM LeelooMinai: It has errors over temp range around 1 deg - it's pretty bad if you compare it to non-ic one.
08:27 PM kyle____: sure, but the temp range is also really wide
08:27 PM kyle____: in reality would you actually be operating it at -40 to 125?
08:27 PM LeelooMinai: Unfortunatelly those steppers tend to work in wide temp range
08:28 PM LeelooMinai: kyle: Those are just ranges where it is still "alive" - you would not really want to approach them.
08:28 PM kyle____: I guess the point I want to make is that they're $4 each
08:29 PM LeelooMinai: Yes, as I wrote, that's why they used them, not because they are a superior solution.
08:29 PM kyle____: it's hackaday :P
08:29 PM LeelooMinai: They just put them on PCB and that's eall.
08:29 PM kyle____: it's a superior solution for them because their main criterion is cost
08:29 PM LeelooMinai: I meant in terms of performance of course.
08:29 PM malcom2073_: Right tool for the right job beats out the best tool for the wrong job
08:30 PM kyle____: sure, but performance is never the only criterion or we wouldn't hire engineers ;)
08:30 PM kyle____: I see your point, they're far from the best
08:30 PM LeelooMinai: Not sure why you think I criticize them or something like that - I just pointed out that it's a budget/ghetto way.
08:31 PM kyle____: sure, but I think they're particularly impressive for being budget/ghetto
08:31 PM LeelooMinai: IC or the whole "thing"
08:31 PM LeelooMinai: ?
08:31 PM kyle____: the whole thing, really
08:32 PM kyle____: but anyway, time to head home, wish me luck with the hayward bridge traffic :(
08:32 PM malcom2073_: Good luck! heh
08:48 PM kanzure_ is now known as kanzure
08:54 PM * roycroft is trying out some citrus strip to see how well it works
08:57 PM jdh: on what?
09:02 PM roycroft: on my lathe tailstock castings
09:03 PM roycroft: i'm doing a slow rebuild of my lathe
09:03 PM roycroft: there's some issue with the half nut engagement, and i need to pull the apron to figure out what's going on
09:03 PM roycroft: so i decided to take the opportunity to rebuild the tailstock and saddle/apron assembly while i'm at it
09:11 PM roycroft: i also need to drill and tap a hole in my saddle for my steady rest - one of the holes does not line up
09:21 PM dioz: roycroft: 13/32nds
09:21 PM dioz: or 21/64ths
09:43 PM LeelooMinai: 32767/65536 drill bit
09:47 PM pcw_home: at room temp...
09:58 PM pink_vampire: hii
10:13 PM cncnoob: hey guys, how do I clear the g54 coordinates?
10:14 PM LeelooMinai: Set them to 0? :)
10:14 PM pink_vampire: what do you mean by clear?
10:14 PM cncnoob: I thought that when I first installed linuxcnc the default "LinuxCNC" text shown for milling in AXIS didn't have G54 set, but now every time I start AXIS it is set
10:14 PM cncnoob: It shows a cyan line on AXIS
10:15 PM cncnoob: I want that line to go away
10:15 PM cncnoob: I think it is throwing things off when I load a new program
10:15 PM pink_vampire: you can send a screen shot?
10:16 PM pink_vampire: do you have skype / discord?
10:16 PM cncnoob: I'll take a screen shot
10:16 PM cncnoob: one sec
10:16 PM cradek_: you can clear the g54 offset. look on the menu.
10:16 PM cradek_: or you can clear it with the appropriate g10 command
10:17 PM cradek_ is now known as cradek
10:17 PM -!- #linuxcnc mode set to +v by ChanServ
10:17 PM LeelooMinai: cncnoob: I guess you should start by defining what is "clear" in your mind.
10:17 PM LeelooMinai: Because it is not... clear.
10:17 PM cradek: in general you will need to set the offset using "touch off" when you change your program or whatever
10:20 PM LeelooMinai: You can use G10, but it's a bit weird, and seldom what you want to do - unless somehow you have rock-solid global coordinates.
10:23 PM pink_vampire: cncnoob: the way I'm using linux cnc: 1. open linux cnc, 2. jog each axis to the home position. 3. click home for every axis. 4. jog the machine to the stating position above the material. 5. click touch off on each axis. 6. run the gcode
10:23 PM cncnoob: My problem may be something else, I just didn't remember the G54 being there when I first started using linuxcnc
10:23 PM cradek: pink_vampire: that is the right thing to (if you have home switches you can skip step 2)
10:23 PM cradek: cncnoob: it is a feature that the g54 offset is saved forever until you change it
10:25 PM LeelooMinai: cncnoob: You cannot have no local coordinate system active - there's no such a thing.
10:25 PM cncnoob: https://imagebin.ca/v/3Qa1sKlToZ6G
10:26 PM cradek: yeah that looks right
10:26 PM cncnoob: humm
10:26 PM cradek: did you read all the responses above?
10:26 PM cncnoob: well, here is the real problem I'm trying to solve
10:26 PM LeelooMinai: cncnoob: Well, it's set to what it is - you can hide the cyan line from a menu, but that's only visual.
10:26 PM cncnoob: yeah
10:26 PM cncnoob: https://imagebin.ca/v/3Qa25RmSVbWK
10:26 PM cncnoob: You can see that tool path that goes way down Z
10:26 PM cncnoob: When I simulate it I don't get that
10:27 PM cradek: click on that line, and see what line of gcode causes it
10:27 PM pink_vampire: jog the machine to where you want and click touch off
10:27 PM pink_vampire: leave it 0.0
10:27 PM cncnoob: Says it is on line 69 of my program, but that is a spindle operation
10:27 PM cncnoob: Didn't realize I could click on a line!
10:27 PM cradek: pastebin the gcode?
10:27 PM cncnoob: that is going to change my life
10:28 PM cncnoob: yeah one sec
10:28 PM LeelooMinai: lol
10:28 PM cradek: cncnoob: yes and you can do the opposite too, clicking on the gcode
10:29 PM cncnoob: https://pastebin.com/q1V2Gsmz
10:29 PM cncnoob: line 75
10:31 PM pink_vampire: drill cycle
10:31 PM LeelooMinai: cncnoob: Your tool table is sane?
10:31 PM cradek: what's T2's Z length in the tool table?
10:32 PM LeelooMinai: G43 will apply whatever is there - it better be reasonable.
10:33 PM cncnoob: I'm trying to get my probe to work, so my tool table is empty except for tool numbers
10:33 PM cradek: do you have tool prep or tool change remapped?
10:34 PM cncnoob: I have remapped M6 and M600 to probe on every manual tool change as described here: https://forum.linuxcnc.org/10-advanced-configuration/5596-manual-tool-change-tool-lengh-touch-off?start=30#48235
10:34 PM cradek: ohhhh
10:34 PM cradek: that's probably the tool change's probe move showing
10:34 PM cncnoob: This is a new program as well
10:34 PM cncnoob: ah
10:34 PM cncnoob: didn't think of that
10:34 PM cncnoob: I might need to adjust where it thinks my probe is
10:34 PM pink_vampire: cncnoob: probe? or a tool setter?
10:34 PM cradek: yeah perhaps
10:34 PM cncnoob: I didn't know what to expect from axis with the probe config in place
10:35 PM cradek: I think it'll show it all
10:36 PM cncnoob: I don't know what a tool setter is. This is what I have. I'm using it as a tool length probe at the moment, not as an edge finding probe
10:36 PM cncnoob: https://www.automationtechnologiesinc.com/products-page/cnc-parts/touch-and-tool-probe-quarter-inch-shaft/
10:36 PM pink_vampire: the probe command is just going to save a variable, then you can do something with it.
10:38 PM pink_vampire: is there any calibration mechanism on this probe???
10:38 PM pink_vampire: they say "It is easily converted from one use to the other in just a few seconds by simply swapping tips and adding or removing the screw-on arbor."
10:39 PM pink_vampire: this is VERY VERY VERY bad!!
10:40 PM cncnoob: yeah, I wasn't planning on using the edge finding freature
10:40 PM pink_vampire: NEVER EVER do something like that!!
10:40 PM cncnoob: Honestly don't buy this probe
10:40 PM cncnoob: why not?
10:40 PM cncnoob: It isn't well designed, but what don't you like about it?
10:40 PM cncnoob: I think it is good for one or the other, but it isn't as easy to switch as advertised
10:41 PM pink_vampire: it will go out of alignment..
10:41 PM pink_vampire: my probe is cost me close to zero
10:42 PM pink_vampire: http://i.imgur.com/yolDisB.png
10:42 PM cncnoob: I thought I could get this probe and get going quick
10:42 PM pink_vampire: this is my probe
10:42 PM cncnoob: I don't have a lot of money, but I have even less time :)
10:43 PM pink_vampire: it
10:43 PM pink_vampire: it
10:44 PM pink_vampire: it's take a lot of time to cnc it.. and then screw few screws...
10:44 PM pink_vampire: (are you sure you are in the right hobby for you) :-) ?
10:45 PM LeelooMinai: Seems monday the senate in US is shutting down. I guess something is broken:p
10:48 PM cncnoob: I'm CNC'ing for a purpose right now, not as a hobby
10:49 PM cncnoob: The fun stuff will come later for me
10:49 PM cncnoob: hopefully :)
10:49 PM pink_vampire: any way' this prove took me very little time to make.
10:50 PM pink_vampire: what kind of machine do you have?
10:51 PM pink_vampire: cncnoob:
10:54 PM roycroft: the citrus strip seems to work well
10:54 PM roycroft: it's been two hours
10:54 PM roycroft: and i was able to easily scrape the finish paint off with a plastic scraper
10:54 PM roycroft: i reapplied to what is left of the primer now
10:55 PM pink_vampire: roycroft: what are you making?
10:55 PM roycroft: paint was really goobered on this machine - it's probably 0.012" thick
10:55 PM roycroft: the half nut does not engage the way i would like on my lathe
10:55 PM roycroft: so i'm disassembling to figure out what's going on
10:55 PM roycroft: and i'm taking the opportunity to rebuild the tail stock and saddle/apron while i'm at it
10:56 PM pink_vampire: cool!
10:57 PM roycroft: i've heard good things about citrus oil based paint strippers
10:57 PM roycroft: and the "citrus strip" brand is what folks seem to like, so i decided to give it a go
10:57 PM roycroft: it's nice
10:57 PM roycroft: no fumes
10:57 PM roycroft: i got some on my hand and was able to just mosey over to the sink to rinse it off
10:58 PM pink_vampire: maybe one day that I will re paint my machine (pink)
10:58 PM roycroft: with the aircraft stripper i've usd in the past it started burning intensely immediately on contact
10:58 PM roycroft: http://www.roycroft.us/LatheOnStand1.jpeg
10:58 PM * LeelooMinai imagines it stripping the paint, then the machine, then making the hole in the concrete floor
10:58 PM roycroft: http://www.roycroft.us/LatheOnStand2.jpeg
10:58 PM pink_vampire: http://imgur.com/a/kS4y9
10:59 PM roycroft: the blue color of the stand is going to be the new color of the lathe
10:59 PM pink_vampire: before and after, just cleaning the original paint
11:00 PM LeelooMinai: What is it... a baby powered hacksaw?
11:00 PM pink_vampire: it's cute
11:01 PM pink_vampire: 1950 power hacksaw
11:01 PM roycroft: it's not loading for me
11:01 PM pink_vampire: http://i.imgur.com/3j7aLU4.png
11:01 PM roycroft: it brings up a page with two question marks
11:01 PM roycroft: meaning there are two images my machine doesn't know how to parse
11:01 PM pink_vampire: http://i.imgur.com/mg4CUkX.png
11:02 PM roycroft: aah, that loads
11:02 PM roycroft: nice
11:02 PM roycroft: a power hacksaw would be fun to have
11:02 PM roycroft: i'm thinking about building a filing machine
11:03 PM pink_vampire: the power hacksaw is SLOOOOW
11:03 PM roycroft: i have a decent bandsaw, so a power hacksaw is not something i could really justify
11:03 PM roycroft: but it would be a cool thing to have
11:03 PM roycroft: slow is no problem
11:03 PM pink_vampire: it is..
11:03 PM roycroft: it does not need to be attended while it's cutting
11:03 PM roycroft: so you just go do something else while it's doing its thing
11:03 PM pink_vampire: 2X3" aluminum stock take 2 hours to cut
11:03 PM roycroft: oh, that's *really* slow
11:04 PM pink_vampire: i told you
11:04 PM roycroft: my band saw would cut that in less than a minute
11:04 PM pink_vampire: it is faster to just cut it with the end mill
11:04 PM LeelooMinai: I have a "swordfish" saw and found bi-metal blades for it in the basement, for metal. I think it's called demolishon saw or reciprocating saw? I will try to cut steel stock soon this way - not sure how it will go:)
11:04 PM pink_vampire: what band saw do you have?
11:05 PM LeelooMinai: demolition*
11:05 PM cncnoob: @pink_vampire it is a HF 44991 that I converted
11:05 PM roycroft: i have a 7x12 import
11:06 PM LeelooMinai: I guess it's like a hacksaw, but only supported on one end.
11:06 PM cncnoob: The probeMinZ I set for my probe operation was causing that rouge line in my program
11:06 PM cncnoob: I had it set to the min Z of my machine, but for some reason that puts the travel outside the envelope by a little bit
11:07 PM cncnoob: Haven't figured out why yet
11:07 PM pink_vampire: cncnoob: the mini mill from HF is a very cool machine. I have the G0704
11:07 PM cncnoob: Awesome
11:07 PM cncnoob: I was trying to get going as cheap as possible
11:07 PM cncnoob: I purchased a used 44991 :)
11:08 PM Crom: a 44991 is still better than a 3040
11:08 PM pink_vampire: cncnoob: definitely the cheap as possible
11:09 PM pink_vampire: cncnoob: do you have a vise?
11:09 PM pink_vampire: http://imgur.com/a/Lcpjh
11:10 PM cncnoob: yeah, but the vise I purchased is too big
11:10 PM cncnoob: I can make it work
11:11 PM cncnoob: but I'm going to get a smaller one and sell the one I have now
11:11 PM pink_vampire: what kind a stuff do you make on it?
11:12 PM cncnoob: looks like that probe operation was pushed outside the envelope because my probeMinZ + my program's max retract height combined to push it outside the envelope
11:12 PM cncnoob: some brackets that need to be precise
11:12 PM cncnoob: and little gears
11:13 PM pink_vampire: "little gears" on the HF mini mill....
11:14 PM cncnoob: It works well
11:14 PM cncnoob: I make a sheet of them with tabs holding each gear in place
11:14 PM pink_vampire: did you cnc thiem, or used a gear cutter?
11:15 PM pink_vampire: sounds very interesting.
11:15 PM pink_vampire: do you have a picture of that?
11:16 PM cncnoob: I CNC them
11:16 PM cncnoob: I don't have a pic
11:16 PM cncnoob: Trying to make money off of it so I probably wouldn't share anyway ;)
11:17 PM pink_vampire: sound like you are re-inventing the wheel
11:29 PM cncnoob: Nah. I had an idea that I think can make me some money. The parts I needed didn't exist so I'm learning how to make my own
11:30 PM pink_vampire: hope for you...
11:31 PM cncnoob: Assuming I got the design right the first time (unlikely) it would have cost me about half the money I put into making my own CNC machine to get fab shop to make the parts for me
11:31 PM * roycroft pours a wee dram of lagavulin 16
11:32 PM cncnoob: Now I can have as many design iterations as I need and it will not cost me any extra
11:32 PM cncnoob: Probe is working great now
11:32 PM cncnoob: Thanks for the help!
11:33 PM pink_vampire: cncnoob: you will be surprised how cheap you can get parts if you ask for large quantity
11:33 PM pink_vampire: home shop is good if you need to make 1-2parts
11:49 PM LeelooMinai: lol: https://asgardia.space/en/
11:58 PM pink_vampire: what is the best / safe way to discharge a fridge compressor?
11:58 PM Wolf_: shoot it from a distance?
11:58 PM McBird is now known as McBride36
11:58 PM Wolf_: or probably use a refrigerant recovery unit
11:58 PM pink_vampire: LOL
11:59 PM * Wolf_ likes shooting things
11:59 PM pink_vampire: in ny it is not a good idea
11:59 PM Wolf_: usually stick to hitting paper, steel plates and clays tho http://i.imgur.com/yb7MRcf.jpg
