06:52 AM TurBoss: brb
06:52 AM XXCoder: cool
11:09 AM JesusAlos: Hi
11:16 AM JesusAlos: In what cases we must use HOME_USE_INDEX?
11:17 AM archivist: when you want to and have one available
11:18 AM archivist: can be more consistent/accurate
12:22 PM IchGucksLive: hi from Germany
12:23 PM IchGucksLive: today i recived a gift from a large factory around
12:23 PM IchGucksLive: 12 pc hightec
12:23 PM IchGucksLive: so i grept a DVD and instaled lxnx 2.7.9
12:23 PM IchGucksLive: lcnc
12:24 PM IchGucksLive: what a miss latency 250000
12:24 PM IchGucksLive: multicore so isolcpu ll of HT VT VM C1E
12:25 PM IchGucksLive: and all the irq to cpu 0
12:25 PM IchGucksLive: and now runnif at 4 glxgears with near 2500frams eatch at 3572ns for 1hr
12:26 PM IchGucksLive: it climbs slightly near 10ns per minute
12:27 PM Deejay: your language is broken
12:28 PM IchGucksLive: JesusAlos: yoiu need home index oly on servos to get to the given next rotation index of the encoder
12:28 PM JesusAlos: Hi
12:28 PM IchGucksLive: Deejay: im pälzer so it is comen
12:28 PM sync: no
12:28 PM sync: it is not
12:28 PM sync: you just need to take a bit more time to write what you want to write
12:28 PM sync: you are almost not understandable
12:29 PM Deejay: indeed
12:29 PM IchGucksLive: im to old
12:29 PM sync: no
12:29 PM IchGucksLive: i miss the keys on the keyboard so offen
12:30 PM sync: which is why you need to take more time
12:30 PM sync: or read what you wrote again and correct if it you made a mistake
12:30 PM sync: otherwise you are just lazy
12:30 PM JesusAlos: I have a problem in a machine. The offset after homing secuence, not ever the same point.
12:31 PM roycroft: or stop drinking hefeweizen before you type :)
12:31 PM JesusAlos: We use inductive swithc. So, I think the problem is the histeresys sensor
12:31 PM sync: roycroft: it is only dangerous if you are past the ballmer peak
12:31 PM IchGucksLive: yes ofcause normal switches are most case more precise
12:32 PM m0n5t3r_: put a scope on it, you may have a noise issue
12:32 PM IchGucksLive: JesusAlos: https://www.ebay.es/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR0.TRC0.H0.Xswitch+8111.TRS0&_nkw=switch+8111&_sacat=0
12:33 PM IchGucksLive: this are the best industrial i got
12:33 PM JesusAlos: I'm using this http://www.dx.com/es/p/sn04-n-sensor-w-cable-black-blue-350734?tc=EUR&gclid=Cj0KEQjwhMjKBRDjxb31j-aesI4BEiQA7ivN-IibSiJzyP7ff-GNJWveIB6Pwv5aeeSZf6gvrbirC5gaAp8W8P8HAQ#.WVKP0mvtZhE
12:34 PM JesusAlos: I see
12:35 PM sync: move the axis manually and see if there is a difference
12:35 PM JesusAlos: But I think, If is a sensor problem, I can solve with index of servo signal
12:35 PM sync: you can use it as a limit switch and then home to the index, yes
12:36 PM JesusAlos: Thank you both
12:37 PM JesusAlos: But I think in pncconf there no are index configuration available.
12:37 PM JesusAlos: I think only by code.
12:38 PM sync: read the documentation, I think it outlines that homing method
12:39 PM JesusAlos: yes.
12:59 PM * phipli bravely installs an nvidia driver update...
01:02 PM LeelooMinai: *phipli is gone for an hour* :p
01:03 PM pink_vampire: hi everyone
01:06 PM IchGucksLive: hi
01:06 PM phipli: evening IchGucksLive - how goes?
01:08 PM pink_vampire: I finished the base part, and now I need to make this part
01:08 PM IchGucksLive: phipli: working on new c installations
01:08 PM pink_vampire: http://i.imgur.com/QwgAur0.png
01:09 PM Tom_itx: what's that drawn with?
01:10 PM phipli: IchGucksLive: "c installations"?
01:10 PM JT-Shop: hey
01:11 PM IchGucksLive: phipli: lcnc wheezy
01:11 PM phipli: :)
01:11 PM phipli: do you have a good book to hand? :)
01:17 PM roycroft: linuxcnc really needs to move beyond wheezy, since stretch is out now
01:17 PM roycroft: being two major os releases behind is only asking for trouble
01:18 PM pink_vampire: Tom_itx: I'm using solidworks
01:18 PM dioz: uuh.
01:19 PM dioz: what kind of trouble?
01:20 PM dioz: i'm gonna go out on a limb and say you probably have your lcnc rig connected to the net
01:20 PM dioz: and you're afraid of security
01:20 PM dioz: if that is the case... you deserver whatever happens to you
01:20 PM JT-Shop: you don't have to use wheezy...
01:21 PM roycroft: my linuxcnc installs are running jessie, jt-shop
01:21 PM dioz: i love when people pretend to IT
01:21 PM roycroft: but the main distribution is still based on wheezy, unless that's changed very recently
01:21 PM Tom_itx: well i just moved from lucid
01:21 PM Tom_itx: and it was working just fine but i lost the GUI and figured it was easier just to upgrade
01:22 PM IchGucksLive: the nw pc has just diesd
01:22 PM roycroft: and the average user is not going to be able to install the rt kernel on jessie
01:22 PM IchGucksLive: wit latency lower then 10k
01:22 PM IchGucksLive: :O
01:22 PM IchGucksLive: glxgears stopt and nothing all freezing
01:22 PM Tom_itx: the _average_ user is using mach. i think we are above average here
01:23 PM roycroft: the average user is buying throw-away goods from wal*mart, not machining anything :)
01:23 PM roycroft: if you want to take it there
01:23 PM pink_vampire: this is the part with the base http://i.imgur.com/gWnzFCC.png
01:23 PM * dioz palms face
01:23 PM IchGucksLive: its the wheezy issue on screensaver
01:23 PM Tom_itx: that would qualify as consumer
01:23 PM roycroft: i think the context was clear in what i said
01:23 PM dioz: the average user isn't using their lcnc machine to surf the internet
01:23 PM dioz: just sayin
01:24 PM IchGucksLive: you can run Lcnc also on ubuntu 16.04 im toald
01:24 PM roycroft: yes, it runs on several oses
01:24 PM dioz: you could probably run it on any distro
01:24 PM IchGucksLive: it is a hard thing to get it run but it runs in rip-envirerment only
01:25 PM IchGucksLive: GOD save 10.04 it brought back the wheezy freeser by editor the lightdm conf
01:25 PM roycroft: my point about updating is that when the main distribution is based on something old and unsupported, less and less hardware will be compatible over time, and os documentation/distrubitions will be harder to find, although debian are pretty good at keeping the really old stuff around
01:26 PM roycroft: even hardware that is supported is not going to benefit from newer, improved drivers
01:26 PM IchGucksLive: ;-)
01:26 PM Tom_itx: i wholeheartedly agree but how often do you change hardware on a working cnc?
01:26 PM roycroft: that's not the point
01:26 PM pcw_mesa: roycroft: there's a test Stretch LinuxCNC ISO available now
01:26 PM roycroft: it's about people installing new systems
01:26 PM roycroft: there is, pcw_mesa?
01:26 PM roycroft: that's great
01:26 PM Tom_itx: yes
01:26 PM roycroft: it seems they skipped jessie
01:27 PM Tom_itx: i was following that a bit this morning
01:27 PM pcw_mesa: 4.9.x Preempt-RT kernel
01:27 PM roycroft: but if there's a stretch iso now, that's good news
01:27 PM pink_vampire: roycroft: the way I see it for my case' is that linux cnc is a tool' (cnc controller) and a took a computer that is fit the needs of linux cnc.
01:27 PM roycroft: although i'm not running stretch in production yet :)
01:28 PM pcw_mesa: Stretch was only released a week or so ago
01:28 PM dioz: i remember this one time i was doing IT for a company that had a machine that would encode all their raw video to a certain format. the machine would always break down and develop issues. i disconnected it from the lan. problem solved. machines with a purpose that don't need a network connection shouldn't be connected to the network. it's a bad scenario in almost every csse
01:28 PM dioz: case
01:28 PM roycroft: pink_vampire: i certainly agree - throughout my career, when folks ask "what computer should i buy?", i've told them to first find the applications that do the work they need, then choose an os that runs their application(s), then choose hardware that runs that os
01:28 PM roycroft: yes, pcw_mesa
01:28 PM roycroft: and i wasn't advocating for linuxcnc moving the main distribution to stretch yet
01:29 PM roycroft: i was just pointing out that now that stretch is current, wheezy is not a good base os any more
01:29 PM CaptHindsight: pcw_mesa: on the 7i77 are all 3 encoder channels for each axis available as 5V TTL inputs?
01:29 PM roycroft: jessie would be fine - it will be fully supported for at least two more years
01:29 PM dioz: why isnt it a good base?
01:29 PM dioz: why why why
01:29 PM CaptHindsight: if configured for single ended
01:29 PM roycroft: but if it's moving to stretch, then that's all the better
01:29 PM dioz: why does it need to be current release?
01:29 PM roycroft: that means at least five years of support for the os
01:30 PM JT-Shop: my plasma don't like the 4.9.x kernel
01:30 PM pink_vampire: I think wheeze is maybe old' but I prefer old disrto that can run on old and cheap hardware, over a new on that must use new computer.
01:30 PM dioz: you need to use facts to prove your supposition
01:30 PM pcw_mesa: Sure, all 6 encoder (18 inputs) can be used for TTL inputs
01:30 PM dioz: this dude is duuuumb
01:30 PM roycroft: dioz: if you haven't figured this out by now, you're nothing but a troll and you can bugger off as far as i'm concerned - so please do not try to engage me
01:30 PM dioz: cause you say dumb things all the time
01:30 PM roycroft: i don't like using /ignore, but if i must i must
01:30 PM dioz: with no evidence or logic
01:30 PM CaptHindsight: pcw_mesa: thanks
01:30 PM JT-Shop: I have 2 CNC machines still running Ubuntu 10.04
01:31 PM dioz: you can't even back up your statement with any logic
01:31 PM Tom_itx: JT-Shop same, mine was working just fine
01:31 PM dioz: i doubt you have any clue what you're talking about
01:31 PM roycroft: pink_vampire: moving the main distrubution to something that is currently in support does not mean that the old distribution must be abandoned
01:31 PM pcw_mesa: CaptHindsight: the trick with muxed encoders is that you must use the encoder A,B,index hal pins fo GP inputs
01:32 PM CaptHindsight: I have an old servo drive with a serial port where the 16b software was made for DOS. I'm having trouble finding a PC here with a serial port
01:32 PM roycroft: installing linuxcnc on jessie was problematic for many, if not most users
01:32 PM pink_vampire: I think in that point, linux cnc need a good and modern interface.
01:32 PM roycroft: as witnessed by a number of folks who have come here for help doing so over the past couple years or so
01:32 PM pink_vampire: this is the main issue of new users
01:32 PM IchGucksLive: pink_vampire: seen touchy
01:33 PM pcw_mesa: or hazzy
01:33 PM IchGucksLive: pink_vampire: most usegmoccapy
01:33 PM IchGucksLive: is hazzy on the new dvd
01:33 PM IchGucksLive: never seen that
01:33 PM pcw_mesa: no its not merged
01:33 PM roycroft: all i was saying is that i think it would be good for the linuxcnc maintainers to put effort into building a distribution that runs on a more current os, as folks want that and for good reasons
01:33 PM roycroft: and hearing from pcw_mesa that it's being done is great news
01:33 PM pink_vampire: I mean to replace axis' with something modern, out of the box. and make it slick and simple.
01:34 PM dioz: roycroft reminds me of a guy i used to work with who'd always wanna update machines the moment updates became available. almost always ended up having to unfuck his messes. pretend IT people know little to nothing about what they speak
01:34 PM dioz: you can't even justify your supposition
01:34 PM roycroft: i don't see how anything i said was in the least bit controversial
01:34 PM CaptHindsight: one of the problems is RTAI for newer kernels
01:34 PM roycroft: the only one one who really objected was our resident troll
01:35 PM dioz: ask any real IT guy if bleeding edge is a smart move
01:35 PM dioz: i dare you
01:35 PM roycroft: and he is just contrary, but that is no longer any concern of mine :)
01:35 PM roycroft: i understand that, capthindsight
01:35 PM sync: it always is. see the petya outbreak
01:36 PM dioz: sync: for certain packages yes... i agree. generally speaking though. unless it's a remote vulnerability it isn't a concern
01:36 PM roycroft: and i don't expect one to be able to install jessie/stretch and do "apt-get install linuxcnc" and expect that to ever work
01:36 PM roycroft: but a linuxcnc livecd running jessie or stretch wouldn't be that difficult to make
01:36 PM sync: no, if there are updates, you update
01:36 PM sync: no questions asked
01:36 PM dioz: but as i said. idk why you'd be connecting your production lcnc to a network
01:36 PM pcw_mesa: test iso's
01:36 PM roycroft: i shall go check out the version that pcw_mesa mentioned
01:36 PM pink_vampire: just look at path pilot' under the hood is just the core of linux cnc, but it got popular and people enjoy using it mostly because the good interface.
01:36 PM pcw_mesa: http://www.linuxcnc.org/testing-stretch-amd64-rtpreempt/
01:36 PM dioz: thay is poor logic
01:37 PM CaptHindsight: roycroft: and to make RTAI matters worse, the official RTAI maintainer won't give anyone credit for their work
01:37 PM sync: it is not
01:37 PM sync: unless there are specific reasons not to update, you update
01:37 PM dioz: lol. i have over 13 years in IT doing linux and unix admin.
01:37 PM dioz: what do you got?
01:38 PM pcw_mesa: hazzy is a bit like Pathpilot (and shares some of its limitations = pretty but non-scalable graphics)
01:38 PM sync: you want to connect your machine to the network to push your code into it
01:38 PM JT-Shop: what is hazzy?
01:38 PM roycroft: open source code maintainers are often the biggest sofware snowflakes around :)
01:38 PM roycroft: software
01:39 PM CaptHindsight: it's also unfortunate that the main users of RTAI are the biggest cheapskates since they don't use Mesa and try to only use the LPT ports for stepping
01:40 PM pcw_mesa: its a GUI written originally to look like a Hass GUI by KCJ, theres a forum thread on it
01:40 PM Tom_itx: pcw_home, who maintains that link?
01:40 PM roycroft: pcw_mesa: i'm actually building a test stretch vm right now for another project
01:40 PM IchGucksLive: im off Gn8
01:40 PM CaptHindsight: so it's highly unlikely that they would contribute anything back to the actual RTAI dev
01:40 PM roycroft: it would be a good time to install the lcnc-stretch test iso as well
01:41 PM pcw_mesa: Pretty sure the devs are looking for Stretch testers
01:42 PM Tom_itx: that' preempt-rt only right?
01:42 PM roycroft: i would likely only be testing in a vm for now
01:42 PM pcw_mesa: Yes Preempt-RT only for now
01:42 PM roycroft: however, after the country fair (which is next week), i'm oging to start putting together the pieces for my mill cnc conversion
01:42 PM roycroft: i don't have ball screws yet, but i'm going to get the electronics working with the stepper motors
01:42 PM roycroft: that might be a good project for testing with stretch
01:44 PM pink_vampire: hazzy it's not a good option, the main goal should me and easy interface that every one can customise to there machine because each user use other machine
01:45 PM pink_vampire: be* an*
01:47 PM pcw_mesa: Have you tried hazzy?
01:48 PM pcw_mesa: the problem with most of the pretty interfaces is that they are fixed format
01:48 PM CaptHindsight: https://www.youtube.com/watch?v=JbPgHUxsEBA Hazzy
01:50 PM roycroft: as in hazzy shade of winter?
01:50 PM CaptHindsight: time time time
01:50 PM pink_vampire: pcw_mesa: this is why I think linuxcnc need a flexible interface, with icon that every one can just drug and drop with the function he need of each machine.
01:51 PM roycroft: oh, i hope that that interface works with a real keyboard
01:51 PM CaptHindsight: https://github.com/KurtJacobson/hazzy
01:51 PM JT-Shop: I've never figured out how you can get by without a keyboard and mouse even with a touch screen
01:51 PM JT-Shop: like updating and file transfers...
01:51 PM roycroft: i find having to use a virtual keyboard with a mouse infuriating
01:52 PM pink_vampire: I'm using the small lenovo keyboard.
01:52 PM cradek_: JT-Shop: on my vmc with touchy, I transfer files TO it with rsync of ~/linuxcnc/nc_files (push them to the machine) and if I need to do any updating etc I just use ssh
01:52 PM cradek_ is now known as cradek
01:52 PM -!- #linuxcnc mode set to +v by ChanServ
01:53 PM JT-Shop: hmm I think I looked at rsync before but usually I'm transferring from my wonders PC
01:53 PM CaptHindsight: roycroft: you just need cap touch like a smartphone :)
01:53 PM cradek: yeah I don't really know how you'd do that
01:54 PM cradek: I don't know how to winders
01:54 PM roycroft: i have a nice, shiny. stainless steel keyboard for my linuxcnc machine
01:54 PM roycroft: it's from a kiosk, and is pretty heavy duty
01:54 PM CaptHindsight: we tried virtual keyboards in the 90's for machines
01:55 PM JT-Shop: when the LinuxCNC PC is cooperating I can drag and drop with the windoze file manager
01:55 PM CaptHindsight: we also gave up using virtual keyboards in the 90's :)
01:55 PM * JT-Shop gets back to work
01:56 PM CaptHindsight: 12 hours ago I was looking for a serial terminal program for freedos
01:57 PM CaptHindsight: I have them saved somewhere
01:57 PM Vitran: Progress! It has lights and turns on! Ready to go into the beast! http://i.imgur.com/GbdFn8w.jpg
01:58 PM CaptHindsight: Vitran: how many axesisies is that? :)
01:59 PM roycroft: capthindsight: kermit?
01:59 PM roycroft: that runs on almost everything
01:59 PM CaptHindsight: yeah
01:59 PM CaptHindsight: looked for a DOS version online
02:00 PM CaptHindsight: reminded me of being on a BBS
02:00 PM CaptHindsight: still awful
02:00 PM Tom_itx: CaptHindsight, what for?
02:01 PM Tom_itx: i bet i still have procomm
02:01 PM CaptHindsight: Tom_itx: old servo drive with serial port and DOS application from ~95'
02:01 PM Vitran: CaptHindsight: 3 axis, two turret Hardinge Superslant lathe
02:01 PM Tom_itx: CaptHindsight did you find what you need?
02:02 PM CaptHindsight: too tired, will look again later, I should have kermit and procomm on a HD here
02:03 PM Tom_itx: pretty sure i do if you can't find it
02:03 PM CaptHindsight: a quick search online turned up lots of junk links
02:03 PM CaptHindsight: thanks
02:04 PM Tom_itx: in fact it's still installed on ------> that pc
02:06 PM roycroft: http://www.columbia.edu/kermit/k95.html
02:06 PM roycroft: that's the canonical site for kermit
02:07 PM roycroft: looks like it's abandonware now
02:07 PM roycroft: but if you can find a download link there and it works, who cares?
02:08 PM Tom_itx: CaptHindsight, still has old bbs numbers in it too :D
02:46 PM Crom: procomm... I'd have to look at my cd's.. I should have a shareware cd if needed
03:10 PM Crom: grrr G03X0z0R45.72 is draing a straight line
03:11 PM Crom: drawing
03:11 PM Crom: ahhh G18
03:27 PM Crom: G18 G03X-45.72Z45.72R45.72F800
03:39 PM Vitran: Wondering if I could talk to someone about how to test pins on my board. I have the board in and powered and want to see what inputs are high or low.
03:39 PM Vitran: Seems like I am missing something simple
03:40 PM TurBoss: you could use halcmd
03:40 PM TurBoss: and write to halp pins directly
03:40 PM TurBoss: I don't remember how
03:40 PM Vitran: I have HAL Configuration open
03:40 PM TurBoss: hal cmd is a command line tool
03:41 PM TurBoss: http://linuxcnc.org/docs/html/hal/tutorial.html
03:41 PM pcw_mesa: if you are running axis you can use "watch"
03:42 PM pcw_mesa: machine --> show hal configuration --> watch --> select pin
03:51 PM Vitran: I have little yellow or red circles that show up. Pressing the button doesn't result in a change. Are the indicators static?
03:52 PM pcw_mesa: no the watch 'LEDs" are dynamic
03:52 PM pcw_mesa: note watch, not show show is static
03:52 PM JT-Shop: show show that was that terrible French machine gun from WW1
03:55 PM Vitran: The pin is getting 12VDC and is a 7i64. Maybe I need 24VDC? I am looking at all pins input to see if there is a change
03:57 PM pcw_mesa: 7I64 input will work from about 4V to 24V
03:57 PM pcw_mesa: inputs
03:58 PM pcw_mesa: but they are all floating inputs so need a + voltage source and ground for each inout
04:00 PM Vitran: They have that
04:00 PM Vitran: Some of the pins are high and some are low
04:01 PM Vitran: but the pins that I am looking at don't seem to change
04:02 PM pcw_mesa: are you running axis?
04:03 PM Vitran: yes
04:04 PM pcw_mesa: if you are running axis and watch (or halmeter) the reading are dynamic (assuming you are communicating= blinky green lights on 7I77/7I64)
04:05 PM Vitran: The 7i77 has blinky lights. Not the 7i64
04:05 PM pcw_mesa: that suggests the 7I64 jumpering/cabling is not correct
04:06 PM Vitran: kk, i
04:06 PM Vitran: 'll look into that. thanks
04:15 PM Andrey_: Hello is the anybody on the channel?
04:15 PM XXCoder: nope
04:15 PM TurBoss: :)
04:16 PM TurBoss: \o
04:16 PM Andrey_: I am looking for information on following controller for LinuxCNC http://www.ebay.com/itm/5-Axis-CNC-Breakout-Board-Optical-Couple-For-Stepper-Driver-Controller-MACH3-/222420211657
04:16 PM Andrey_: Does anybody tried it out?
04:18 PM cradek: it's not super clear what that is
04:19 PM cradek: and whatever it is, according to the text, they may just send you something else instead
04:19 PM XXCoder: I has BOB from aliexpress that works well
04:19 PM cradek: so ... it's a $5 gamble
04:19 PM cradek: you might get something useful, you might not
04:20 PM XXCoder: that one looks virtually same as mine
04:21 PM roycroft: i'm a mesa man :)
04:23 PM cradek: yes for only 10x the money you'd get something really useful and with good support
04:24 PM Vitran: Checked wires. The pins connecting the 7i77 to the 7i64 are as per the diagrams, which is annoying. Unless the RX+ doesn't connect to TX+
04:24 PM m0n5t3r_: I see optocouplers, what looks like bus buffers, a relay... it will need testing to map the pins, but there's not much to get wrong there :)
04:24 PM Andrey__: Still here...
04:24 PM XXCoder: Andrey__: whats your machine anyway
04:25 PM XXCoder: it was fine for my machine, I used tb6600s with it
04:25 PM m0n5t3r_: on the other hand, I find it sad that people still use parallel ports in $current)year
04:25 PM XXCoder: m0n5t3r_: invent new rt commucation system then
04:25 PM Vitran: I have built a laser cutter, an engraver, and a plotter using parallel ports. That one looks like it would be fine to link up with LinuxCNC
04:26 PM Andrey__: @ m0n5t3r_ well then what would you suggest as an alternative for low cost?
04:26 PM Vitran: The breakout board is the easy part. Getting good stepper drivers is the bigger issue for those machines
04:26 PM sync: XXCoder: it already exists
04:26 PM m0n5t3r_: no idea, that's why I said it's sad :)
04:26 PM sync: ethernet
04:26 PM XXCoder: Vitran: depending on using, tb6600 works fine
04:26 PM XXCoder: sync: ethernet is not rt
04:26 PM sync: it is
04:27 PM sync: for reasonable definitions of realtime
04:27 PM XXCoder: swo, no
04:27 PM m0n5t3r_: I spent 2 days getting to know the system and now I have a stepper moving on a beaglebone black, but I can understand why people prefer PCs and larger monitors
04:27 PM XXCoder: does it have int to cpu?
04:28 PM Andrey__: @Vitran: well if there is a computer with parallel port around then why not try to give it a new life? I think that parallel port if fine and find that it quite easy to communicate with from inerpreter language (python, perl and others).
04:28 PM roycroft: nagging mothers-in-law have mastered realtime communication
04:28 PM roycroft: hire some of them to work on your new protocol
04:28 PM sync: there is no need to have an int line to the cpu XXCoder
04:28 PM m0n5t3r_: the problem with any linuxcnc-over-the-network is the network
04:29 PM sync: and yes, most phys will interrupt if they have data waiting
04:29 PM Vitran: Andrey__: the issue is you have limited inputs and outputs with the machine. If your steppers lose a step, you are screwed. Some people are fine with that. You could also check out GRBL, but I do like LinuxCNC more
04:29 PM XXCoder: Andrey__: anyway that BOB and 3 tb6600 would work fine if your machine is not fancy
04:30 PM Vitran: Funny, I learned one of the guys at the model engineering club I am part of is one of the authors of GRBL.
04:30 PM m0n5t3r_: my MPCNC is controlled by GRBL and cncjs running on an orange pi zero
04:31 PM m0n5t3r_: working on replacing it with BBB + machinekit with touchy
04:31 PM XXCoder: Vitran: yeah though it really depends on what Andrey__ machine is, which he havent menioned yet.
04:32 PM sync: if it was such a problem a mesa card would not work or ethercat would also not work XXCoder
04:32 PM XXCoder: well time for me to run machines at work lol
04:33 PM Andrey__: @XXCoder: let say the machine is P4 2.8GHz, 4GB RAM, WD250GB
04:33 PM XXCoder: no, the cnc machine
04:33 PM Andrey__: CNC machine will be home build
04:33 PM XXCoder: yeah bob and 3 tb6600 would work fine
04:33 PM XXCoder: unless you wanna encoders and such
04:33 PM pcw_mesa: With a decent CPU Ive had year long uptimes with 4 KHZ servo thread over Ethernet
04:34 PM pcw_mesa: Realtime over vanilla Ethernet is very possible
04:34 PM XXCoder: now off to work I go
04:34 PM JT-Shop: have fun
04:34 PM XXCoder: pcw_mesa: yeah? that'd be great replacement then
04:34 PM XXCoder: bye
04:36 PM m0n5t3r_: btw, be careful what TB6600 you get; if it says 1/32 microstepping it ain't TB6600, it's TB67S109AFTG
04:37 PM m0n5t3r_: ... which isn't a bad chip, but the implementation I've seen is a (bad) joke
04:37 PM m0n5t3r_: let's say that big hunk of aluminium is useless because it contacts the chip on the plastic side
04:38 PM pink_vampire: hi XXCoder!
04:39 PM pink_vampire: XXCoder: I did also the base http://i.imgur.com/gWnzFCC.png
04:39 PM Andrey_: @XXCoder: yes I was checking out on tb6600 type motor driver and as I do not have any experience on motors and controllers I decided to explore this area -- this how I got here...
04:43 PM Andrey_: Does anybody could make a recomendations on "How to build your own CNC machine for small cost?" (Note, at the moment I have limited access to tools as I live in an apartment, but could ask some people I know for tools)
04:43 PM pink_vampire: Andrey_: what type of cnc machine?
04:43 PM roycroft: there are as many types of cnc machines as you can imagine, and more
04:44 PM pink_vampire: dremel based machine?
04:44 PM roycroft: a bit more specificity would be helpful :)
04:44 PM m0n5t3r_: Andrey_: I already had a 3d printer, so I built an MPCNC :)
04:44 PM m0n5t3r_: but yeah, it would be useful to know what you want to build
04:44 PM roycroft: what do you want to do with this machine?
04:44 PM roycroft: that is the first question
04:45 PM Deejay: gn8
04:45 PM Andrey_: Well, at this time I am looking at building a machine to cut wood .... may be later to use this machine to cut aluminium parts for next machine.... Or it is bad idea?for
04:45 PM pink_vampire: Andrey_:http://www.instructables.com/id/Easy-to-Build-Desk-Top-3-Axis-CNC-Milling-Machine/
04:45 PM roycroft: 2d, 2-1/2d, 3d?
04:45 PM Andrey_: Yes, the first machine should be 3 Axis...
04:47 PM pink_vampire: Andrey_: what size of parts?
04:47 PM Andrey_: The idea is to use inexpencive materials like plywood to build first machine... later use it to cut same/better part out of aluminium sheets (10-12mm).
04:48 PM m0n5t3r_: you could make one with drawer slides, M8 / M10 screws, nema17 motors and particle board or plywood
04:48 PM m0n5t3r_: it will be slow, but cheap
04:48 PM Andrey_: pink_vampire: I would say size somewhere around 30x40cm...
04:48 PM m0n5t3r_: moving gantry type, like most of the routers out there
04:48 PM pink_vampire: Andrey_: did you saw that? http://www.instructables.com/id/Easy-to-Build-Desk-Top-3-Axis-CNC-Milling-Machine/
04:49 PM Andrey_: @mOn5t3r_: exactly, this is what I am talking about.... it is just to get feet wet, to get to know a little bit more how to do it "right"...
04:49 PM pink_vampire: also' you can get very cheap lead screw machines from ebay / aliexpress for 200~
04:50 PM m0n5t3r_: not at 30x40cm, tho, that's reasonably large
04:50 PM JT-Shop: I need to sell my Enco mill and make some room in here
04:51 PM Andrey_: One more question: is there a free library of 3D models let say for doors at kitchen -- I am sure that somebody already has these models but I have no idea where to find them.... I just do not want "to invent the bicycle" at time of building my first "plywood" CNC machine
04:52 PM pink_vampire: doors at kitchen????
04:54 PM m0n5t3r_: must be a literal translation of something :)
04:54 PM pink_vampire: Andrey_: https://buildyourcnc.com/default.aspx
04:55 PM Andrey_: pink_vampire: yes at kitchen for capboards let say with "imprints" of moose, or birds or may be lynx..
04:56 PM pink_vampire: I'm more in to metal working
04:56 PM m0n5t3r_: look for "free cnc furniture projects", there are a few sites
04:56 PM m0n5t3r_: thingiverse may have some too
04:57 PM Andrey_: @pink_vampire: something like this http://www.pdjinc.com/Cabinet%20door.jpg
04:58 PM m0n5t3r_: that's 3d carving already
04:58 PM pink_vampire: it is based on your cam software
04:59 PM pink_vampire: it start as grayscale image, and the darker the color the deeper the cut
05:00 PM pink_vampire: Andrey_: ^
05:00 PM m0n5t3r_: oh, that's how they're done? I thought the process would be more like slicing models for 3d printing (which requires an actual 3d model)
05:00 PM Andrey_: pink_vampire: what I ment is not to go all cycle through -- take picture, turn it black and white and then make 3D model out of it -- I am more interested in "download, may be convert in proper format and load in CNC software".
05:01 PM pink_vampire: it is just an image
05:04 PM Andrey_: pink_vampire: Well the CNC machine on Instructable build out of pipes -- I do not have proper tools to work on metal of this caliber.... I can try to ask people I know if they have such tools.
05:05 PM pink_vampire: Andrey_: https://buildyourcnc.com/default.aspx
05:05 PM pink_vampire: look here ^
05:05 PM pink_vampire: there is several machine on that link
05:06 PM andypugh: Andrey_: This chap here made alumnium golf-cart wheels on an all-wooden router: https://www.youtube.com/playlist?list=PLbk9nWCQacMOS4R4y0ZO-EjFfbRWMi8xA
05:08 PM pink_vampire: Andrey_: also a very good web sitehttp://openbuilds.org/
05:08 PM Andrey_: @pink_vampire: I am checking "buildyourcnc" website -- quite a bit of information,, I need make "head and tails" of it... I will do it later..
05:10 PM pink_vampire: http://openbuilds.org/
05:11 PM Andrey_: @ pink_vampire: I am trying to get to "openbuilds" but internet a little sluggish for some reason....
05:12 PM Crom: right now I'm having the router cut it's own mounts. Router is strapped to the bed, and the work piece is on the Z.
05:12 PM Andrey_: @ pink_vampire: well "OpenBuilds" look quite interesting.... I will explore it later... thank you for reference...
05:13 PM pink_vampire: but I'm thinking is much much easier to get cheap body from eaby and upgrade it as you go.
05:13 PM Andrey_: Thanks everyone for provided links.... I will drop in time to time ... it was a pleasure to chat with all of you... (Note: I am "talking" through PChat for first time and not figured out how to use it at full potential.

05:24 PM pink_vampire: it is look much nicer then the g0704
05:24 PM Crom: g0704 can take bigger cuts
05:24 PM Crom: and swing a bigger tool
05:25 PM pink_vampire: but the rails are garbage.
05:28 PM pink_vampire: Crom: ^
05:33 PM Crom: it can be scraped

05:39 PM pink_vampire: why?
05:39 PM andypugh: It just seems odd to me.
05:39 PM pink_vampire: 10 mm from the top, center of the stock
05:40 PM andypugh: Is your Z pointing the right way, it doesn’t seem to be
05:40 PM roycroft: i need to get this metal etching project going - i have everything i need now
05:40 PM roycroft: and a disassembled tailstock ready for paint and a new badge
05:40 PM pink_vampire: andypugh: the right is X
05:41 PM andypugh: Y seems to be pointing up, you want Z pointing up?
05:41 PM pink_vampire: andypugh: it its point up
05:41 PM pink_vampire: look at the coordinate system
05:42 PM andypugh: Yes, sorry. Blue is Z isn’t it? It just has a Y next to it

05:51 PM pink_vampire: I'm trying now to do it with 2d pocket.
05:52 PM Crom: I just hand coded a file to cut my router mounts. using G16 G02 and G18 G02
05:52 PM Crom: g03
05:52 PM pink_vampire: andypugh: pocket work fine!
06:15 PM andypugh: Which wasn’t working?
06:29 PM Tom_itx: if you change servo_period in the ini settings how will this affect things in the hal file like delays etc or stepper timing?
06:33 PM Vitran: I got a dumb question. On a lathe, I have a 0 point sensor, a spindle pin engaged sensor, and a spindle pin retracted sensor on top of the collet closed and open sensors. What does a spindle pin and a 0 point do?
06:34 PM Tom_itx: 0 point may be the beginning of the angular degrees of rotation
06:35 PM Tom_itx: would the spindle pin disengage the spindle from the drive system?
06:37 PM Vitran: Why would someone do that? I was thinking that the 0 point would be for where the pin is located so it could be put back. Also, this machine could have live tooling, so maybe that is what the 0 point is for
06:37 PM Tom_itx: it was a guess
06:38 PM Vitran: Thanks for the thought. To separate the spindle from the drive system... could be

08:27 PM malcom2073: Heh, buddy of mine says "Hey, I've got a friend who wants something made, can I send him your way?"
08:27 PM malcom2073: "Sure, I haven't had to educate anyone on the cost of doing machine work lately"
08:49 PM Crom: friend of mine is picking up a used G0704
08:50 PM Crom: if's in the shop of a A&P mechanic at our local air port.
08:51 PM Crom: It should be in pretty good shape
08:54 PM pink_vampire: Crom: I have the G0704, and it is very nice machine, the only issue is the horrible rails on the Z axis, and the slow speed spindle.
08:55 PM Crom: spindle speed can be fixed, cleaning, scraping the rails on the Z should take care of that
08:57 PM pink_vampire: Crom: the cast is very soft, and the rails wear very fast in un-uniform way
08:58 PM Crom: ahhh that'll take extra work
08:59 PM pink_vampire: the most common way to fix it is just to install H rail
09:02 PM sync: they only wear if you use no lubrication
09:03 PM Crom: To harden cast iron take ½ pint vitriol (sulphuric acid), 1 peck common salt, ½ pound saltpeter, 2 pounds alum, ¼ pound prussiate potash, and ¼ pound cyanide potash, dissolve in 10 gallons of water. Heat iron to a cherry red, dip, repeating until hard enough. http://chestofbooks.com/crafts/machinery/Receipts/Methods-For-Heat-Treatment-Of-Cast-Iron.html
09:03 PM pink_vampire: sync: it is common issue with the G0704
09:04 PM sync: idk, mine has seen lots of use and there is no wear in the z axis
09:06 PM pink_vampire: I think the cast is not the same on every machine

09:14 PM pink_vampire: O_o WoW!!
09:15 PM LeelooMinai: Must take a special kind of person to buy that...
09:18 PM pink_vampire: LeelooMinai: Polished sterling silver.
09:18 PM pink_vampire: how they make the silver springy?
09:21 PM LeelooMinai: If it breaks, you can always buy new one:)
09:22 PM pink_vampire: I don't understand why to make it from silver from the beginning
09:23 PM sync: because of the swag
09:23 PM LeelooMinai: It hink seeking reason in a product like that is not a good idea...
09:25 PM LeelooMinai: BTW, I bought an epoxy at HomeDepot, in a tube the size of, well, normal caulking tube, etc. then at home I discivered it's sized exactly so it does not fit into the normal dispenser... Then I read the label and there it was: made in USA and everything was clear.
09:26 PM LeelooMinai: Had to cut a bit of the end of the tube with snips or what they are called.
09:27 PM LeelooMinai: Barely manged to squeeze the thing out:)
09:27 PM LeelooMinai: And yes, they want one to buy their own dispenser...

11:37 PM LeelooMinai: Ok, I guess you do:p
11:38 PM Crom: each 1/2 mount has a m6 x 30mm cap screw in the center back. so they can swivel and adjust to the router
11:39 PM LeelooMinai: Also, lol @ that "1 HORSEPOWER" on the router
