12:05 AM Gene_home: good evening
12:07 AM XXCoder: hey
12:12 AM Crom: yo
12:21 AM Gene_home: any preference in tomach ER collets ER16 vs er20 vs er32 vs er40
12:21 AM XXCoder: dunno I use er11 lol
12:21 AM Gene_home: price?
12:21 AM XXCoder: small machine. lol
12:22 AM Gene_home: makes sense
12:22 AM Crom: er20 for anything up max er20 size, er32 for stuff from er20 to max er32, ...
12:22 AM Gene_home: do you have cheap options for any I listed?
12:24 AM XXCoder: cheaqp might have center problems so it has runout
12:24 AM Crom: or go ER16, ER25, ER40
12:24 AM Gene_home: so tormach is the perfered place to purchase?
12:24 AM Crom: depends on accuracy requirements..
12:25 AM Crom: if you have tool post grinder and have the time, go cheaest and fix.. or spend the money..
12:25 AM newcnc22: @archivist.... 3d objects...
12:26 AM Gene_home: this is new to me.... so I purchase a R8 3/4 collet, then setup an ATC that uses the tormach ERxx?
12:26 AM Crom: tormach TTS holders.. they can be ER but not always
12:28 AM Crom: the Tormach TTS 3/4 R8 collet is shortened so it doesn't stick out.. the face of the spindle is ground so the TTS locates on it, not the collet
12:28 AM newcnc22: My homeing configuration in Linux CNC is driving somewhere when I press it but I want to have a reference point. Also the button says "homing all" instead of "home".
12:29 AM Crom: newcnc22: is it going the wrong direction?
12:29 AM newcnc22: No but it's driving somewhere but I want to have to register this point..
12:30 AM Crom: in blah.ini in blah dir of ~/linuxcnc/configs/ there is home point, and home switch location..
12:30 AM Crom: leeme find the config lines
12:30 AM newcnc22: It should have this point where I drive manually to have a zero point of the workpiece
12:31 AM Crom: zero point of work piece is not home... the's machine location specific
12:31 AM newcnc22: I have changed the homeing behavior in ini in the sections of the axis 20 but it didn't work.
12:32 AM newcnc22: To 0 not 20
12:33 AM Crom: which line HOME = or HOME_OFFSET?
12:38 AM newcnc22: HOME SEQUENCE = 0
12:38 AM newcnc22: HOME OFFSET = 0.000000
12:38 AM Crom: HOME_SEQUENCE is which ones homes first, Mine is Z=0, X and Y both equal 1, which means Z homes then X and Y home at the same time
12:39 AM newcnc22: Ah ok...
12:39 AM Gene_home: Crom: what is the benefit to having multiple ER collet sizes, vs using a single ER32 ?
12:40 AM newcnc22: The machine should stay where it is and use the homeing position as a reference point
12:40 AM Crom: HOME_OFFSET is where the home switch is... on my Z it's at 1.000mm, X it's -5.000mm and Y it's -3.000mm
12:40 AM Crom: HOME on mine all say 0
12:40 AM newcnc22: Ok
12:41 AM Crom: Gene_home: cost... a full set of er16's is cheaper than a set of the same size er32's
12:42 AM Crom: newcnc22: after it homes it goes to the HOME = position (machine position)
12:42 AM Gene_home: Crom: excellent answer. I am trying to find a drill bit holder for the tormach setup....
12:43 AM newcnc22: Yes, but it's wrong it should stay there where it is
12:43 AM Crom: you should come out cheaper having the 3 ER TTS holders and the sizes graduated to the smaller holder they'll fit in
12:44 AM Crom: machine position 0 is machine position 0, it's not a G54 workpiece location
12:45 AM Crom: Gene_home: there are TTS holders with Jacobs tapers
12:46 AM newcnc22: I have no home switches
12:46 AM Crom: hmmm....
12:50 AM Gene_home: ok.... any wisdom regarding keyless chucks JT1 vs JT2 Vs JT6 other than size?
12:50 AM Crom: is there a home all for a system not having any homing switches..
12:50 AM Crom: all mine are keyed... so dunno
12:50 AM XXCoder: nope
12:50 AM XXCoder: mine is "home"
12:50 AM Gene_home: Crom: and the reason you like keyed?
12:50 AM XXCoder: has to position machine hit home for each axis
12:50 AM Crom: one was $15 and one was free
12:51 AM Crom: I forgot how once I had home switches mounted permanently
12:51 AM Crom: err sensors and switch
12:53 AM Crom: nite all.. gettng tired.. it's 2223... been up since 0430
12:54 AM Gene_home: Crom: Thanks! Have a good one
12:55 AM XXCoder: hes right though
12:55 AM XXCoder: its easier to add adopter to go down in size than up
12:55 AM XXCoder: though what is useful max size ios up to you
12:56 AM XXCoder: honestly er32 is common at work, rarely see larger ones used
12:56 AM XXCoder: then its honking huge tools
12:57 AM newcnc22: @crom thanks anyway
12:59 AM Gene_home: anyone here order parts from Weiss in China? http://www.weiss.com.cn/
01:00 AM XXCoder: wow site uses flash
01:00 AM XXCoder: that is getting fairly rare
01:00 AM Crom: newcnc22: I didn't tend to hithome... I'd use mdi and g0z0x0y0
01:02 AM Crom: now it's g53 g0x0y0z0
01:06 AM Tom_itx: i would move z first
01:06 AM XXCoder: yeah
01:06 AM XXCoder: I would recommand never do 3d move unless special reason like helix digging
01:07 AM Tom_itx: eventually you will figure out why
01:16 AM IchGucksLive: morning from germany
01:17 AM IchGucksLive: crom depending on where hoome is not a good idee to go g53
01:17 AM IchGucksLive: all zero
01:25 AM XXCoder: hey
01:26 AM XXCoder: IchGucksLive: I made the electrics 2020 box lol but havent done more
01:26 AM XXCoder: too lazy to do much lately :(
01:27 AM IchGucksLive: it will get as you do
01:27 AM IchGucksLive: what is inside
01:27 AM XXCoder: what will be inside you mean heh
01:27 AM XXCoder: 2 PSU, BOB PWM control for spindle, and 3 tb6600s
01:27 AM IchGucksLive: http://tv-profi-gmbh.de/elek_mini.jpg
01:27 AM XXCoder: likely a fan of some sory
01:28 AM XXCoder: I definitely need the wire fence thingy, whats it called again?
01:28 AM IchGucksLive: http://foengarage.de/4achs_elek.jpg
01:29 AM XXCoder: those rows of "fingers" that hold wires, whats it called?
01:30 AM IchGucksLive: wire channel ?
01:30 AM IchGucksLive: http://heimwerkermarkt-tretter.de/schrank.jpg
01:30 AM IchGucksLive: the gray ones
01:30 AM XXCoder: so it is. thanks
01:31 AM XXCoder: any suggestions on connectors? I want nice disconnectable connectors for steppers and various sensors
01:32 AM IchGucksLive: XXCoder: XLR is quide good
01:32 AM IchGucksLive: and fastron
01:33 AM XXCoder: whats max amp?
01:33 AM IchGucksLive: 12A 220V
01:33 AM IchGucksLive: and for the sensors use M12
01:34 AM XXCoder: 12v is way past my machine requirements so should be great.
01:34 AM XXCoder: http://www.electronicspecifier.com/cms/images/old/pr29399a1.jpg ?
01:35 AM IchGucksLive: Cheep ones are GDM only 50cent and 16A
01:36 AM IchGucksLive: https://www.reichelt.de/?ACTION=3;ARTICLE=52149;SEARCH=gdm%203
01:36 AM XXCoder: thank
01:37 AM XXCoder: I'm still thinking on hgow to design mine heh
01:37 AM XXCoder: so its nice and accessable when need fix.
01:37 AM XXCoder: my spindle stopped in middle of run and restarted. one wire for data for pwm was slightly loose
01:37 AM IchGucksLive: every connection reduces speed
01:37 AM XXCoder: so yeah want em all nice and secure
01:38 AM IchGucksLive: i do not use connectors in the stepper circuit as the elektronics is always mounted to the mashine
01:39 AM IchGucksLive: the securest and most used is the HAN
01:39 AM XXCoder: mine isnt so have to do that
01:39 AM XXCoder: so I can disconnect and connect as needed
01:40 AM XXCoder: I'm also figuring if I can mount my entire computer inside box, it is big enough I think.
01:40 AM IchGucksLive: https://www.reichelt.de/?ACTION=3;ARTICLE=75719;SEARCH=han%20a
01:41 AM IchGucksLive: see the catalog side https://www.reichelt.de/bilder/blaetterkatalog/B2C/DE-DE/hkaktuell//index.html?SID=92WPxDWawQATIAADq9wUo5c510c990f33358cfc9959384a390463#page_1050
01:42 AM XXCoder: bunch of options not vad
01:42 AM IchGucksLive: go 2 sides back
01:42 AM IchGucksLive: for neutronics
01:42 AM IchGucksLive: bucannears ....
01:43 AM XXCoder: interesting theres usb sealed machine connectors
01:43 AM XXCoder: ethernet so on too
01:43 AM IchGucksLive: lots of options depending on budget and mounting plate size
01:44 AM XXCoder: indeed.
01:44 AM IchGucksLive: i holpe i coudt get you more input but it most also a pain on decision
01:45 AM IchGucksLive: i got the real catalog on my knies ;-)
01:45 AM IchGucksLive: and the parts as in storige 24h away
01:48 AM XXCoder: ebay is kinda broken, pictures wont load. weird.
01:48 AM XXCoder: well off to amazon I go
01:50 AM IchGucksLive: XXCoder: look on side 1256...
01:50 AM IchGucksLive: printers to dream offf
01:51 AM XXCoder: ah SLA printers
01:51 AM XXCoder: those is very expensive. on aliexpress its not too bad, $200 to $300
01:51 AM XXCoder: and apparently glass can be done now
01:51 AM XXCoder: http://www.3ders.org/articles/20170420-german-researchers-use-stereolithography-to-3d-print-tiny-glass-structures-at-low-temperatures.html
01:52 AM IchGucksLive: its PC in the lowest filament order
01:53 AM IchGucksLive: i find the davinci jr from xyz the best price use value
01:53 AM IchGucksLive: at 360euros
01:54 AM XXCoder: probably. my machine is $150 usd lol
01:55 AM IchGucksLive: ok im off
01:55 AM XXCoder: later
01:55 AM IchGucksLive: have a nice sunday
01:55 AM XXCoder: read the glass article
01:56 AM IchGucksLive: i did
02:13 AM Deejay: moin
02:34 AM yasnak: you guys have seen this right? http://academy.titansofcnc.com/
02:34 AM XXCoder: no
02:35 AM yasnak: Been watching it for awhile, he has a TV show. Thought it was some BS poser at first but he seems legit after the latest videos. Kind of really wish this blew up
02:36 AM archivist: anyone who starts with sign up and wants your email.....
02:37 AM XXCoder: is it captioned?
02:37 AM XXCoder: people almost never think of that.
02:38 AM yasnak: I mean sign up with another email if you want
02:38 AM yasnak: He offers tons of info
02:39 AM yasnak: and legit how to program, design, manufacture videos
02:39 AM XXCoder: and captions too?
02:39 AM yasnak: you can get most from youtube too, this seems to be getting much larger. His show has him installing a machine shop within a prison and training them to machine. Its pretty cool.
02:40 AM yasnak: CC? yes
02:40 AM XXCoder: must pay?
02:40 AM yasnak: totally free
02:41 AM XXCoder: I suppose I will check em out as I might be missing some cnc stuff
02:41 AM yasnak: most of his videos on the site are on youtube, without email address: https://www.youtube.com/watch?v=-evsXTr6q1o for example
02:41 AM yasnak: https://www.youtube.com/user/titanamericanbuilt
02:43 AM XXCoder: one is autocaptioned
02:43 AM XXCoder: one has none
02:43 AM XXCoder: nah forget it
02:43 AM XXCoder: too ADD-ish videos
02:43 AM XXCoder: unwatchable to me
02:46 AM wicki_: hi again
02:46 AM XXCoder: hey
02:47 AM wicki_: whats is the difference between the "not" and the "invert" components in hal ?
02:48 AM XXCoder: wild guess, NOT means input is zero for compare proposes and second just inverts signal, if 1, 0, if 0, 1. but then I havent done HAL stuff yet
02:51 AM wicki_: hmmm... I'm using "not" for inverting boolean true to false~
02:51 AM wicki_: it works.... ;-)
02:51 AM XXCoder: yeah programming NOT is invert signal
02:51 AM XXCoder: dunnon on HAL
02:54 AM wicki_: hmmmm, who has.... ? just want to know - ist this a correct solution?
02:54 AM wicki_: net ZhomeInv not.0.in <= hal_gpio.pin-13-in
02:54 AM wicki_: net home-z not.0.out
02:57 AM archivist: test it, if it works yes elso no
03:06 AM wicki_: archivist: as i said: it works - I just was wondering why there are a "not" and an "invert" component
03:11 AM archivist: not the same thing
05:55 AM jthornton: morning
05:56 AM XXCoder: hey jt
05:57 AM Deejay: yo
05:57 AM malcom2073: Morning
07:41 AM wicki_: how can I list the loaded hal-components ? in "Linux raspberrypi 4.4.4-rt9-v7+ #7 SMP PREEMPT RT" they are not listed in "lsmod"
07:42 AM archivist: http://linuxcnc.org/docs/html/hal/halshow.html
07:44 AM jthornton: normally you open a terminal and do halcmd show pin
07:49 AM wicki_: thats it.... "halcmd list comp" - thx
08:10 AM beginner: hi
08:10 AM beginner: i want to use linuxcnc for a step four basic 540 mill
08:11 AM beginner: i have a dell precision m6600 with parallel port on the docking station
08:12 AM beginner: version of linux allready installed is ubuntu 16.04
08:12 AM archivist: run the latency test on it first
08:12 AM beginner: hold on...havent scared yoou guys yet :))
08:13 AM beginner: should i go with the latest low latency kernel provided 4.06 or a preemptive rt kernel ?
08:14 AM beginner: this is the first issue ...i ahvent reached the part where i install the linuxcnc
08:14 AM archivist: or the livecd to just test the hardware
08:15 AM beginner: it has a core i7 at 2,2 ghz and 32 gb of ram
08:15 AM archivist: you dont need that much ram
08:15 AM archivist: gimme
08:16 AM beginner: whoa...the computer will be used for other things too....so no givin' yet :)))
08:16 AM archivist: in general cnc does not always share well
08:17 AM beginner: while the cnc operates i will refrain to use the pc for other development purposes or net surfin'
08:17 AM beginner: so with that in mind...
08:18 AM archivist: you can do a latency test to see what you can do
08:18 AM beginner: should i go with the preemptive rt which probably i have to build and dont know how...or use the deb package for kernel 4.06 low latency?
08:19 AM beginner: is there a command in terminal for that or i have to burn a cd with linux cnc ?
08:19 AM archivist: test, I cannot say which will be best
08:19 AM beginner: what mill do you use?
08:20 AM archivist: shove it on a usb stick and boot off that
08:20 AM archivist: my mill has no name, beyond fugly mill
08:20 AM beginner: how do i do that on linux.... in a graphical environment?...not dd stuff
08:21 AM beginner: aah diy mill or chinese...i get it
08:21 AM archivist: there are instructions on the website somewhere
08:21 AM archivist: I made it, 5 axis
08:21 AM beginner: ok...diy then
08:22 AM beginner: mine has 3 i want to use it for pcb milliing
08:22 AM archivist: it is actually parts from other machines in a lump
08:23 AM beginner: the idea is that i do not want to install more kernels and then not needding them ....i know how to install but i am not good at removing them afterwards
08:24 AM beginner: in windows is add remove programs....in ubuntu there is..."deal with them"
08:24 AM archivist: most of us dedicate the pc to the machine
08:25 AM beginner: while the machine will operate i will not launch other programs.....i do not have too much space either
08:27 AM beginner: ok.....back to square one i guess
08:28 AM beginner: any known way of installing latest linuxcnc version on an allready installed ubuntu 16.04 ?
08:28 AM beginner: easy way that is
08:28 AM archivist: I never do that
08:29 AM beginner: aah...so i do not forget...
08:29 AM archivist: fresh machine new install, just works
08:29 AM beginner: are there plugins for linux cnc that i should know about?
08:30 AM archivist: open ended question, yes
08:30 AM beginner: like CAM plugins converters for pcb gerber files, photos,etc to machine code, and other as such?
08:31 AM beginner: do you have any examples of such programs....for linux and free...and good and not crashing :) ?
08:32 AM archivist: some are default and just there
08:32 AM archivist: others are new
08:32 AM archivist: it is an old project so not many crashes
08:33 AM beginner: do you know any site to dowload such plugins?
08:33 AM beginner: or more sites? :)
08:33 AM archivist: you questions are too general
08:33 AM archivist: peruse the website a bit
08:34 AM beginner: i want to convert gerber file from kicad to machine code for the mill for example
08:34 AM beginner: what do i use for that...this one is specific
08:34 AM archivist: cheaper(and better) to get a pcb made
08:35 AM beginner: please....i am in a third world country....so there :)
08:36 AM beginner: and you dont make prototypes in china ...you being in the oposite part of the planet
08:36 AM beginner: not having much money
08:36 AM archivist: china makes pcbs for almost nothing compared to making a cnc that cannot do as good a job
08:36 AM beginner: and other details about pooredom inserted here
08:36 AM beginner: :))
08:37 AM beginner: or poverty ...sorry my native language is not english
08:37 AM archivist: I understand poor far better than you might imagine
08:38 AM archivist: which is why a chinese pcb is cheaper and better than making a mill to mill one
08:38 AM beginner: then tell me sites that you know having other linuxcnc plugins so i can have a look too...pretty please...with a cherry on top
08:39 AM beginner: ...when you are in an accessible country that is :)
08:39 AM archivist: google nativecam
08:39 AM beginner: thank you this is what i need...examples...please give more
08:41 AM beginner: wow....has video tutorials too...ok i am convinced to still try to find way to install linuxcnc
08:44 AM beginner: i am building an open source sound card...completely open source...so....yes i need as much help with th availability of tools as possible
08:45 AM beginner: so ...thank you for the nativecam example archivist....please give more examples of plugins if you have...that are not allready included in the linuxcnc installation
08:47 AM archivist: a sound card will need gold plated fingers, double sided and pth which is beyond milling
08:49 AM beginner: first i will use thorogh whole straps in place of vias
08:50 AM beginner: problem solved for prototyping
08:50 AM archivist: the cost of the mill outstrips china costs
08:50 AM jdh: cheap pcb fab might be more useful
08:51 AM beginner: i cannot go on a kickstarter with these kind of little details unsolved:)
08:51 AM beginner: it is just for prototyping....please understand that
08:51 AM beginner: i am not going to build hundreds or thousands of products...on a mill
08:51 AM archivist: I understand prototyping PCBs rather better than you might think
08:52 AM archivist: some of my boards http://www.collection.archivist.info/searchv13.php?searchstr=pcb+design
08:52 AM beginner: then you understand that these are the deices i have on hand...and these i will use
08:52 AM beginner: devices
08:52 AM beginner: the keyboard starts to rust
08:52 AM archivist: none milled at all, something I will never do
08:54 AM beginner: yes but this is what i have...i am not going to use the mill just for that...the product will need enccasing, bracket...etc
08:55 AM beginner: i understand your point of view...but is related to what you have...i have to walk on the steap road...beacuse...this is what i have
08:55 AM beginner: for now atleast
08:57 AM beginner: after the prototype works correctly ....will see who backs it up on a croudfunding... very long road until then
08:58 AM beginner: then i will use the cconventional...pcb production:))....this what i meant
08:58 AM archivist: making a case and brackets is sensible, the pcb is not
09:00 AM beginner: why not?...it is just a 2d plane ...simpler than 3d...and i have the mill available nonetheless :|
09:01 AM beginner: except the software THAT I HAVE TO INSTALL that is :)))
09:02 AM beginner: caps was meant for my pityfull situation ...not that you have any fault in this
09:02 AM beginner: thanks again for the nativecam existence tip by the way
09:04 AM beginner: so....i will install the premptive rt if it has a version atleast as new as ubuntu 16.04
09:04 AM beginner: if not low-latency kernel to the rescue
10:03 AM {HD}: Im going to do a wheezy64 with preemptRT today.
10:04 AM {HD}: I was going to try mint but I realized I dont care. This is JUST a machine control machine
10:14 AM enleth: is there any reasonable way to zero the DRO in axis while the machine is in the off state?
10:15 AM enleth: the MDI panel is disabled, even for G92 etc.
10:15 AM enleth: and it won't accept a G92 anyway
10:16 AM enleth: "it" being the backend, not MDI panel
10:21 AM enleth: (as for why would I want to do that - sometimes I use the mechanical handwheels while axis acts as my DRO)
11:08 AM IchGucksLive: hi all
11:08 AM IchGucksLive: it is a nice sunny day here in germay
11:09 AM IchGucksLive: sad we did not get the expected and realy needed rain
11:13 AM roycroft: if i could, i should be happy to give you some of our rain
11:14 AM IchGucksLive: it is still time
11:15 AM IchGucksLive: the first harvest in india is underway they wil get 4 full harvest periods this year if the waterlevel is up
11:15 AM IchGucksLive: so dont beat on WEAT or corn this year
11:17 AM roycroft: we have the biggest snowpack in decades here
11:17 AM roycroft: i should not complain - we've been short on water for many years
11:17 AM roycroft: but this winter we had way more than average snow
11:17 AM roycroft: up in the mountains
11:17 AM IchGucksLive: in california a real 5year draught
11:17 AM roycroft: and we've had a very rainy spring
11:17 AM roycroft: yes, but that's over
11:18 AM roycroft: the sierra nevada has almost record snowpack as well
11:18 AM IchGucksLive: what happed to the overspill of the large dam
11:18 AM roycroft: the dam was not destroyed
11:18 AM IchGucksLive: no but media got hazard
11:18 AM IchGucksLive: as news in the us dont make research
11:19 AM roycroft: i don't recall the details, but the situation was resolved
11:19 AM IchGucksLive: its the years of draught
11:19 AM IchGucksLive: that made the fault decision
11:20 AM IchGucksLive: if you expect so many you need to lower early
11:20 AM IchGucksLive: even if then you might get up wit only 2/3 to anothere long period
11:21 AM IchGucksLive: ok im off BBQ sunday till later
12:30 PM IchGucksLive: hi from a sunny germany
12:34 PM {HD}: Hey, what gives? http://dpaste.com/0V9GNNC
12:35 PM {HD}: I cannot add the LinuxCNC Archive Signing Key ^^^
12:35 PM IchGucksLive: use root
12:36 PM IchGucksLive: sudo apt-key adv --keyserver hkp://keys.gnupg.net --recv-key 8f374fef
12:46 PM {HD}: IchGucksLive: Look at my dpaste...I was root
12:48 PM {HD}: Can I manually pull and add key?
12:49 PM Jymmm: keys.gnupg.net: Host not found
12:49 PM IchGucksLive: maybe the server is down
12:50 PM {HD}: I just did a 'isserverup' and it is...Must be blocked...Gotta reroute my traffic...
12:51 PM IchGucksLive: {HD}: https://wiki.ubuntuusers.de/apt/apt-key/
12:52 PM {HD}: I would think that these site would realize that ISP Spying/Exploiting is profitable that lots of people are going to use VPNs and to not just blanket block all VPN traffic.
12:53 PM Clownshoes is now known as insomnia
12:59 PM CaptHindsight: {HD}: did you get the serial ports going?
01:01 PM {HD}: CaptHindsight: no but I have some new hardware on the way. I am now playing with wheezy64 and preempt rt
01:02 PM {HD}: I got hung up on step #7 because (I think) of my VPN... http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html#_alternate_install_methods
01:13 PM Crom: now it's nite nite\soon you'll be playing with Jessie64 and liunuxcnc 2.8.0-pre1
01:13 PM Crom: well I'm up now
01:15 PM Crom: morning every one..
01:29 PM IchGucksLive: Crom: night is falling here in germany
01:43 PM CaptHindsight: Crom: going to stick with preempt_rt vs RTAI on 64b?
01:56 PM Crom: linuxcnc - preempt_rt is basically what you're stuck with at the moment for 4.9.13
01:59 PM CaptHindsight: the next bump up for RTAI will be after we start using Ryzen
01:59 PM CaptHindsight: I think memleak was up to 3.16
02:00 PM IchGucksLive: im off Gn8
02:06 PM Crom: I'm at -13.5mm yay!!!
02:08 PM Crom: now at -14mm
02:09 PM Crom: 2 more laps and it should start boring
02:11 PM CaptHindsight: how many mm per lap?
02:11 PM CaptHindsight: micro-jogging? :)
02:21 PM {HD}: What is the difference between RTAI and Preempt_RT? I need to build a local caching server not routed through the VPN so, I can add this keyserver.
02:25 PM Crom: .5mm doc per layer
03:04 PM pjm: evenings chaps! has anyone used the kress milling motor 800FME ?
03:06 PM chopper79: I have been cleaning up that used VMC I purchased and doing a retrofit on. It amazing how far chips will travel and where they get packed into over the years.
03:06 PM chopper79: Kind of like the previous owners never cleaned it for the last 30 years
03:13 PM CaptHindsight: {HD}: they are both real time kernels, RTAI is faster since it's a dual kernel and runs the RT threads on one kernel and non-RT on the others
03:13 PM CaptHindsight: your RT application might not require RTAI
03:14 PM CaptHindsight: it depends on fast you need to go
03:29 PM Crom: These are really nice and they hold a shitload of power http://www.ebay.com/itm/Lumsing-10050mAh-External-Portable-Battery-Dual-USB-Power-Bank-For-Cell-Phone/132098061095
03:31 PM CaptHindsight: I have one about 2x that capacity with USB and a laptop output
03:31 PM CaptHindsight: comes in handy on long flights without power
03:32 PM The_Ball: is 1024 counts per mm considered low today/
03:32 PM Crom: I like the price
03:32 PM Crom: buck an amp
03:33 PM Roguish: The_Ball: all depends on what you're doing. cutting roofing tiles, probably not,
03:51 PM {HD}: CaptHindsight: Thanks for the data. So, it takes longer to develope the RTAI kernel? So it falls behind the Preempt?
03:54 PM Deejay: gn8
04:00 PM Crom: at -26 in the left bore..
04:08 PM CaptHindsight: {HD}: very few active RTAI devs (2-3)
04:08 PM {HD}: CaptHindsight: how does anything ever get done with only 3 devs?
04:09 PM CaptHindsight: well it's mostly just one
04:10 PM CaptHindsight: you put your nose to the grindstone and keep pushing
04:17 PM Crom: leadshine easy steppers... http://americanmotiontech.com/products/integrated-motors/integrated-closed-loop-stepper-motors/ not cheap, but still work it...
04:18 PM Crom: worth it
04:18 PM Siggi: Hey y'all, I'm setting up a Taig Micromill with the DSLS 3000 controller, and I've been trying to figure out the step timings. Can't find anything definitive on the InterWebs, and the manual is worse than useless. Anyone go the low-down?
04:18 PM Crom: what chips is the DSLS 3000 using
04:19 PM Siggi: Dunno - this is from the ... um ... mill manufacturer
04:19 PM Crom: tb6600 is 10us step pulse and 20us dir pause
04:19 PM Crom: hang on lemme look
04:19 PM Siggi: it's not a straightforward driver
04:19 PM Siggi: http://www.microproto.com/MMDSLS.htm
04:20 PM Siggi: the motors have encoders and the steppers allegedly run in a closed loop
04:20 PM Siggi: it fires "limit" errors if the loop breaks
04:20 PM Siggi: (like when I crash :( )
04:22 PM Crom: Siggi I went with JMC-motor NEMA23 2nm (283ozin) integrated closed loop steppers... $114 each... using a ebay parallel Break out board (BOB)
04:23 PM Crom: I have an ALM that outputs 5v if the get outside steps limit
04:23 PM Siggi: cool, but I'm trying to use the supplied control box
04:23 PM Siggi: actually, I'm using it
04:24 PM Siggi: with 5000/5000/1200/1200 the X/Y/A run just fine
04:24 PM Siggi: the Z not so hot
04:24 PM Crom: I'd go with 10000ns timing for step and 20000ns for dir
04:24 PM roycroft: i just found a discontinued grizzly lathe that is essentially the same as mine
04:24 PM roycroft: and grizzly has parts for it
04:24 PM Crom: 1200 sounds low... I have to use 6000
04:25 PM * roycroft is happy
04:25 PM * Crom is happy for roycroft
04:25 PM roycroft: i just ordered new wipers, and replacment knobs/levers that are missing on mine
04:25 PM roycroft: and they have a steady rest and follow rest in stock for it
04:26 PM Crom: grizzly has a 3 jaw chuck that'll fit mine as well as a center for the headstock spindle
04:26 PM Crom: and drive plate
04:26 PM roycroft: i'm waiting until i see what else i end up spending on getting it going before getting those, but it's good to know they're available
04:26 PM roycroft: easier than making my own or remodeling one that doesn't quit fit right
04:26 PM roycroft: i think their spindle is different from mine
04:27 PM roycroft: and some of the gearing is different
04:27 PM roycroft: but some is the same
04:27 PM roycroft: i like the quietness of the belt drive system
04:27 PM Crom: Siggi: I'm using 2700/2700/6500/6500 for mine...
04:28 PM roycroft: but i already don't like moving belts around to change speeds
04:28 PM roycroft: i can see a vfd in my near future
04:28 PM Crom: belts are nice when you need more torque...
04:28 PM roycroft: i'll probably just keep the belt drive system intact, set the main drive belt to the middle position, and continue to use the back gear when i need to go really slow or have lots of torque
04:29 PM {HD}: who is mr. rtai?
04:29 PM Crom: with a VFD and a proper motor... you should be fine except for rare cicumstances
04:29 PM roycroft: yes
04:29 PM roycroft: to be honest
04:29 PM roycroft: the main thing i don't like about belt drive is that i'm used to using the top of the headstock to store my tooling and stuff
04:29 PM {HD}: Does Mr.RTAI develop for machine control or is he using audio or video RT editing or something else?
04:29 PM Siggi: Crom: thanks - this is using the DSLS 3K controller?
04:29 PM roycroft: and i can't do that if i have to flip it open all the time
04:30 PM Siggi: or some other gitup?
04:30 PM Crom: I need to finish getting my treadmill working on the lathe
04:30 PM Crom: Siggi: different setup... start slow, then keep testing pushing it hard, until you have to go back and slow it down a bit
04:31 PM Crom: I should be able to use 2500/2500/6000/6000, though I think I have some antenuation.. so running a bit slower at 2700/2700/6500/6500
04:32 PM Crom: antenuation or inductance...
04:33 PM roycroft: hmm, i should order another hour meter while i'm at it
04:33 PM roycroft: i like using them to keep track of scheduled maintenance
04:33 PM Crom: I should get one for mine
04:33 PM roycroft: i put hour meters on almost everything
04:34 PM Crom: hobbs is your friend
04:34 PM Crom: cq cq kb8wmc de kf6pqz
04:38 PM Siggi: Hmmm, looking at the manufacturer-supplied Mach3 config, it looks like 6000 is a sensible value for step, and 1-2K for dir
04:38 PM Siggi: so I guess I goofed something else on the Z
04:44 PM Crom: DOH! 608 bearing has a 8mm hole... just stuck a 608 bearing on top of my spidle to space the drill motor up so it doesn't run
04:44 PM Crom: rub
04:47 PM JT-Shop: been screwing up the same pair of parts all damn day finally got to rights but I need a right and a left :(
04:47 PM Crom: at -39.000mm1mm to go of this bore
04:47 PM Crom: at -39.000mm, 1mm to go of this bore
04:49 PM Crom: -39.5
04:49 PM Crom: -0.5mm to go... msybe -0.6mm
04:52 PM roycroft: you are boring us with your bore
05:02 PM TurBoss: hello
05:03 PM TurBoss: I have glade-gtk2 but can't see any gladevcp component
05:07 PM TurBoss: ok just after run ". ./scripts/rip-environment" glade-gtk2 shows the vcp components
05:07 PM TurBoss: thanks
05:22 PM {HD}: http://imgur.com/a/ijEfK
05:22 PM {HD}: My results with current install.
05:22 PM {HD}: and 10 gears
05:23 PM {HD}: I am using nouveau driver...Should I just go generic or maybe with the nvidia?
05:27 PM TurBoss: nvidia is not compatible with realtime iirc
05:28 PM {HD}: Is nouveau the generic or is there a differnt driver?
05:36 PM Loetmichel: *maaan* What a week. I just managed to finish the last of three military IT device prototypes. I did 10 hours yesterday and 14 hours today (additional to the usual 10 hours for the 4 days before that). And my boss just jumped into his cayenne and will drive that shit to the customer in denmark... has to be there tomorrow at 13:00 or wie will not be considered in that bit project tender.
05:36 PM Loetmichel: respect, that man is 72. and had a 16 hours day today on top of the 8 hours drive he is doing now!
05:36 PM XXCoder: now thats good leadership
05:37 PM XXCoder: I remember this picture lemme see if can find
05:37 PM XXCoder: http://msl-cdn.radiantforestllc.netdna-cdn.com/wp-content/uploads/2013/05/boss-vs-leader-800x800.png
05:39 PM Loetmichel: yeah
05:43 PM SpeedEvil: Loetmichel: Where are you, Iforgot
05:43 PM Loetmichel: Offenbach am main, germany
05:44 PM Loetmichel: XXCoder: considering that he is 72 years old i was surprised that he lasted til now at all. Its not like he had twiddling thumbs while i built the last prototype today
05:45 PM XXCoder: I notice that some older people just get tougher as they age
05:46 PM XXCoder: its due to keeping exercising up all time
05:48 PM Crom: 72... in 20 years I'll be there
05:49 PM XXCoder: 31 for me
05:50 PM Loetmichel: 24 for me
05:50 PM Loetmichel: :-)
05:50 PM Crom: arduino.cc is driving me up the wall... PORTE is not defined...
06:12 PM {HD}: Ugh the default debian de is aweful
06:15 PM XXCoder: https://xkcd.com/1309/ this is perfect way to state how I feel about infinite pages.
06:20 PM malcom2073: Wait, infinite pages?
06:20 PM malcom2073: Oh, like facebook does?
06:20 PM XXCoder: yeah websites that keep adding content
06:20 PM XXCoder: yeah
06:20 PM XXCoder: I hate those
06:20 PM malcom2073: It is verry annoying for searching
06:29 PM agentmulder: Hello all
06:45 PM XXCoder: southern style hash brown, now with golf balls!
06:46 PM JT-Shop: whew got those PIA parts finished and installed
06:46 PM Crom: https://xkcd.com/1815/ damn this needs to be out new flag... the the presidential approval rating as the battery level
06:47 PM XXCoder: lol
07:01 PM JT-Shop: good night
07:01 PM Crom: good night jt
07:14 PM Siggi: k, in case this is archived: I took a scope to the output of the Mach3 controlled UC100 module. It's generating 5us step pulses on the dot for the X axis at least. I couldn't really measure the direction setup time, except that it's in ms.
07:15 PM Siggi: So setting the timing to 600/600/10000/10000 cleans up my Z-axis
07:15 PM Siggi: good enough for the DSLS 3000
07:44 PM XXCoder: dang!!!
07:44 PM XXCoder: http://www.huffingtonpost.com/entry/boy-drives-across-australia_us_58fcd410e4b06b9cb917a79e
07:44 PM XXCoder: crazy
07:44 PM XXCoder: 800 miles is pretty hard, and 12 year old boy did it
07:50 PM sync_: 1200km, ~11h or so
07:53 PM XXCoder: approx 1/4 of way there
08:06 PM Crom: DONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
08:38 PM skunkworks: http://electronicsam.com/images/KandT/testing/20170423_155152.jpg
08:39 PM skunkworks: .005 backlash added vs 0
08:59 PM roycroft: nice
09:00 PM roycroft: i indicated the edge of the backing plate on my lathe, and there was 0.002" runout
09:00 PM roycroft: then i indicated the outside of the spindle, and there was less than a 0.0001" runout
09:01 PM roycroft: i will remove the chuck and measure the taper and spindle end at some point, but got tired of bending over for today
09:12 PM Crom: cut out with the band saw
09:12 PM Crom: now I have to wait for payday so I can order some boring bars
09:15 PM Crom: then I can finish the holes to size and get some bars to block it up on, then I can clamp it down and fish the face
09:15 PM Crom: s/fisj/finish/
09:18 PM XXCoder: roycroft: can flatten backing plate?
09:20 PM roycroft: it's out of round
09:20 PM roycroft: i don't know about flatnes
09:20 PM roycroft: s
09:21 PM roycroft: but if it's not flat, then yes, i can
09:21 PM roycroft: the machine has been crashed a couple times, at least
09:21 PM roycroft: that might have bent the backing plate
09:21 PM XXCoder: ahh ok
09:21 PM roycroft: as long as the spindle runs true, i'm not worried
09:23 PM XXCoder: true
09:24 PM XXCoder: thopugh maybe just use lathe circulize and flatten backing plate
09:25 PM roycroft: that's how a backing plate is trued - on the spindle
09:26 PM XXCoder: ahh
09:26 PM XXCoder: so spindle is prerry good
09:26 PM XXCoder: .0001"
09:27 PM roycroft: well, i did not indicate the important part yet
09:27 PM roycroft: but that the outer part ran that true is a good sign
09:27 PM roycroft: i'll remove the chuck and indidate the register the end, and the taper
09:30 PM roycroft: i'm going to try to get another four vacation days over the next week and a half
09:30 PM roycroft: i got my shop tidied up today so that i can move machinery around
09:31 PM roycroft: but i still have to do all the moving to make an area big enough and safe enough to weld up the lathe stand
09:31 PM roycroft: and then mount the lathe and rearrange things
09:31 PM roycroft: not to mention painting the stand
09:31 PM roycroft: i'm not going to repaint the lathe until i disassemble and refurbish it, but i want to paint the stand right when i build it
09:32 PM XXCoder: good planning
09:32 PM roycroft: yeah, it will rust otherwise
09:32 PM roycroft: plus, i want to start building the drawer units for the stand soon
09:33 PM roycroft: i also have at least a day and a half of desperately needed yard work to do
09:33 PM roycroft: i hope my boss agrees to the extra vacation days
09:33 PM roycroft: i usually take a week off in march for spring cleaning and getting the garden going
09:34 PM roycroft: but i did not this year, so i see this as a delayed march holiday
11:08 PM XXCoder: https://forum.linuxcnc.org/forum/18-computer/25927-reducing-latency-on-multicore-pc-s-success
11:08 PM XXCoder: nice
11:08 PM XXCoder: less than 4k ns jitter
11:27 PM Jymmm: What mobo is what I'd like to know
11:27 PM tiwake: Jymmm: looks like core2duo machines
11:28 PM Jymmm: t12: I have chittons of C2D machines. from laptop to desktops, from generic, to hp to apple. make/model of mobo and it's BIOS/CMOS verisons
11:28 PM Jymmm: is what would be helpful
11:29 PM Jymmm: The best machine was a used one off ebay, that lil fucker is surprisingly damn fast for what it is
11:29 PM XXCoder: looks like guy pushed everything to one cpu
11:30 PM XXCoder: and linuxcnc on other cpu
11:30 PM XXCoder: so cpu was very free
11:30 PM Jymmm: MY mac mini, slugs along
11:30 PM tiwake: among other things
11:30 PM roycroft: i almost got a mac mini to use as a media center
11:31 PM tiwake: screw that
11:31 PM roycroft: now i have a nice freenas machine that is both my media server and file server
11:31 PM tiwake: mac mini would be horrible... not extendable with any devices, has no extra SATA ports or hardly anything
11:32 PM tiwake: at the moment my server plans are on a ryzen system, cause cheap ECC supporting processors
11:33 PM Jymmm: Cause ecc ram is not cheap =)
11:33 PM tiwake: its not bad
11:33 PM roycroft: i bought a nice machine on lease return for my freenas server
11:34 PM roycroft: http://www.ebay.com/itm/132098335210
11:34 PM roycroft: except i got it for a lot less than the asking price
11:34 PM roycroft: i'm a regular customer of mr_rackables
11:35 PM roycroft: i had to toss the raid controller and get a proper hba for freenas, but other than that it was the perfect machine
11:35 PM tiwake: I plan on putting three western digital red drives in, 4tb
11:36 PM tiwake: 1.33tb/platter, so three platters per 4tb drive
11:36 PM roycroft: i ended up getting 4TB seagate ironwolf drives
11:36 PM tiwake: they reportably run really cool
11:36 PM tiwake: http://rml527.blogspot.ca/2010/10/hdd-platter-database-western-digital-35_9792.html
11:37 PM roycroft: but i'd have gotten the wd reds if the price had been better
11:37 PM roycroft: the ironwolfs are 5900rpm
11:37 PM roycroft: and they run pretty cool as well
11:37 PM Crom: RAM is dirt cheap these days... figure 16MB 23 years ago was $400
11:37 PM roycroft: it's the folks who pack a buttload of 10,000 or 15,000 rpm drives in a tiny case who have problems
11:37 PM tiwake: enh, with a SSD cache it won't really matter
11:38 PM Crom: 40 years ago 16KB was $400
11:38 PM roycroft: and they're not at all necessary with freenas
11:38 PM tiwake: http://www.phoronix.com/scan.php?page=news_item&px=Btrfs-Linux-4.12-RAID-5-6-Fixes
11:39 PM Crom: inflation adjusted that 16KB was $2000 in todays money
11:39 PM tiwake: if they do get the RAID fixes, I might put that on my not-yet-built server
11:39 PM tiwake: Crom: lol... yeah.. DDR4 ECC memory is rather cheap
11:40 PM tiwake: no way I could make DDR4 ECC memory that cheap
11:40 PM Jymmm: roycroft: "get a proper hba" what you get?
11:40 PM tiwake: therefore its a good price
11:41 PM Crom: think I just spent $30 a while back on a 2GB stick for my linuxcnc machine (most it'll support)
11:41 PM roycroft: lsi 9211-8i
11:41 PM roycroft: zfs doesn't like raid controllers abstracting the disks
11:43 PM Jymmm: Looks like a good chassis, gonna be loud though =)
11:43 PM Crom: $5000 https://losangeles.craigslist.org/sgv/tls/6061774851.html
11:44 PM roycroft: if you're talking about mine, it sounds like a jet engine when it gets warm
11:44 PM roycroft: but it lives in a room where i don't
11:45 PM Crom: $2700 16x60 Le Blond
11:45 PM Crom: https://losangeles.craigslist.org/lac/tls/6089346805.html
11:45 PM Jymmm: When I had my server in the datacenter, I knew which cabinet it was in cause I could hear it before I even got close and that was even other all the other cabinets and the servers running in them
11:45 PM Jymmm: it's hostname.... banchee
11:46 PM Jymmm: 6x 15K RPM fans
11:46 PM roycroft: yeah, that's one of those "sells for less than scrap because it would cost too much to get rid of it" machines
11:46 PM Jymmm: the little whiny fuckers
11:47 PM * roycroft will be happy with a 12x36 for the indefinite future
11:47 PM Jymmm: YAY 50% completed , 6 hours to go
11:49 PM Jymmm: 12 hours to rebuild the array after replacing a failing 2tb hdd
11:50 PM roycroft: when i built my new freenas server i torture tested all the drives for a week before i built the vdev
11:50 PM roycroft: but after i started loading it up with files one of the drives failed
11:50 PM roycroft: it only took a few hours to rebuild once i got the replacement drive, but that's because there was not much data yet
11:51 PM roycroft: i anticipate it will take 3-4 days to rebuild once all the data are there
11:51 PM roycroft: but i built it as raidz-2, which has two parity disks
11:52 PM roycroft: and i don't have to offline it to rebuild
11:52 PM roycroft: it's just degraded during the resilvering, and writes are a lot slower than normal
11:52 PM roycroft: but reads have almost the same performance
