12:15 AM pink_vampire: this is look soooo nice!
12:54 AM IchGucksLive: hi from Germany
12:55 AM hazzy1: Those are nice! Would sure beat a dremel tool
12:55 AM hazzy1: Hi!
12:55 AM XXCoder: hey
12:55 AM LeelooMinai: Not in the price/performance ratio...
12:55 AM IchGucksLive: i woudt go for proxxon IBE 50 on that
12:55 AM XXCoder: very high rpm
12:56 AM hazzy1: GN8
12:56 AM IchGucksLive: yeah ofcause but it slowes down so fast
12:57 AM IchGucksLive: you can get car Airtools for realy good price
12:57 AM IchGucksLive: likewise here in town the toolwizzard lady
12:58 AM IchGucksLive: https://werkzeugfee.de/
12:58 AM IchGucksLive: she is like pink
12:59 AM IchGucksLive: kije ger with 3-6mm at 25USD
12:59 AM IchGucksLive: https://werkzeugfee.de/16-tlg-PROFI-Winkel-Stabschleifer-SATZ-Druckluft-Schleifer-SET-90-abgewinkelt

01:00 AM IchGucksLive: this things are quite cheep
01:01 AM IchGucksLive: pink_vampire: you got it
01:01 AM pink_vampire: the dental stuff need very low scfm
01:01 AM pink_vampire: 1.9 SCFM @34psi
01:02 AM IchGucksLive: but it only got to deel with teeth and this is not ike AL
01:03 AM pink_vampire: i want it for high speed finish pass
01:04 AM IchGucksLive: agree on speed but not on price
01:05 AM IchGucksLive: performence for the low price is up to 80% of the dental but price is less then 20%
01:05 AM pink_vampire: http://www.ebay.com/itm/Dental-NSK-Style-Low-Speed-Handpiece-4-Hole-Straight-Contra-Angle-Air-Motor-Kit-/121408448831?epid=1960400648&hash=item1c4481e93f:g:ZXEAAOSwImRYNrIt&autorefresh=true
01:06 AM pink_vampire: IchGucksLive:
01:07 AM IchGucksLive: best to go for
01:08 AM pink_vampire: for?
01:21 AM IchGucksLive: im off
01:30 AM roycroft: many of us are a little bit off
01:30 AM XXCoder: me too
01:30 AM XXCoder: going though really bad dizzy spell
01:36 AM -!- #linuxcnc mode set to +v by ChanServ
01:42 AM MacGalempsy: hello
01:43 AM XXCoder: hey the drill master
01:43 AM MacGalempsy: its slow tonight. we only made 600ft in 24hrs
01:44 AM pink_vampire: hi
01:44 AM XXCoder: mac wanna me go over and help? just $50 a hour lol
01:44 AM XXCoder: not sure if I would actually help you guys drill any faster ;)
01:45 AM MacGalempsy: thats more than i make
01:45 AM XXCoder: and way more than what I make lol
01:45 AM MacGalempsy: its not lime the old days of 90/hr
01:46 AM XXCoder: yeah evenually oil and coal will end
01:46 AM XXCoder: coal IS dying now. oil will take a while longer
01:46 AM MacGalempsy: natural gas is the best
01:47 AM MacGalempsy: but work is work
01:47 AM XXCoder: I'd love to avoid working at places where high pollution is from, or making war stuff
01:47 AM XXCoder: but like you said work is work
01:48 AM MacGalempsy: the best part of the day is that my wife and i agreed on going to Yellowstone
01:49 AM MacGalempsy: PinkVampire: got your pic here
01:49 AM MacGalempsy: https://flic.kr/p/VV7hw4
01:49 AM MacGalempsy: you bring the marshmallows
01:50 AM XXCoder: nothing like oil fire flavored marashmallows.
01:50 AM MacGalempsy: thats just from the beans they made for dinner :)
02:20 AM pink_vampire: MacGalempsy: wowwww that is amazing!
02:22 AM MacGalempsy: yeah! usually they close a choke and it doesnt get that big.
02:22 AM MacGalempsy: they will bleed it off slowly and the flares are smaller
02:23 AM pink_vampire: how do you kill it?
02:26 AM Deejay: moin
02:27 AM pink_vampire: morning Deejay
02:28 AM Deejay: hey pink
02:34 AM pink_vampire: Deejay: how are you?
02:49 AM MacGalempsy: pink_vampire: to kill it you either let it burn until the pressure dies off, or up the mud weight
02:49 AM Deejay: thanks, fine, and you?
03:14 AM XXCoder: https://www.youtube.com/watch?v=WffR6HrEqTA
03:14 AM XXCoder: I want to swim in that
03:21 AM evil_dan2wik is now known as dan2wik
04:17 AM XXCoder: yo Crom ya in?
04:18 AM pink_vampire: ?
04:18 AM XXCoder: guess not lol
05:31 AM jthornton: morning
05:31 AM XXCoder: hey jt
05:53 AM Tom_itx: moin
05:53 AM XXCoder: hey
05:53 AM jthornton: yo
05:54 AM Tom_itx: jt, i installed mate on my debian lcnc install. do you know how to get rid of the original manager?
05:54 AM Tom_itx: xcfe iirc
05:54 AM Tom_itx: on login it asks which to use but i don't wanna log in either... that is next on the list
05:55 AM jthornton: I always install mate with the livecd and check off auto log in I guess you can uninstall it somehow
05:56 AM Tom_itx: i didn't see an option when i installed it
05:56 AM jthornton: yea debian doesn't have anything to make your life easy
05:57 AM XXCoder: its generally not safe to uninstall orginial manager
05:57 AM XXCoder: but same time maybe better since last time I did
06:29 AM XXCoder: hey Cromaglious_
06:29 AM XXCoder: lol if anyone is looking for new career, aircraft companies REALLY need new pilots. they need 255,000 more pilots across 10 years. pretty lot.
06:33 AM Loetmichel: XXCoder: says who?
06:35 AM XXCoder: http://www.huffingtonpost.ca/2017/06/20/pilot-jobs-cae-report_n_17221004.html
06:35 AM XXCoder: 105,000 is just to replace retiring pilots
06:36 AM XXCoder: lol I would love to fly planes
06:36 AM XXCoder: but never will happen.
06:36 AM Loetmichel: why not?
06:36 AM XXCoder: deaf.
06:36 AM Loetmichel: ups
06:37 AM XXCoder: ups?
06:37 AM Loetmichel: thats a handicap for getting a polit job
06:37 AM Loetmichel: pilot
06:37 AM XXCoder: thats for sure yeah
06:38 AM Loetmichel: ups-> german for "oops" (for making that blunder)
06:38 AM XXCoder: ahh ok :)
06:38 AM XXCoder: in theory I can do any job
06:38 AM XXCoder: but theres theory and theres reality
06:39 AM XXCoder: it would take too much work for me to be able to work as pilot lol
06:46 AM Loetmichel: i dont know if you can even get a commercial license if you cant hear the radio traffic at all
06:47 AM XXCoder: yeah
06:47 AM XXCoder: im sure it is possible to figure a workaround but why?
06:48 AM XXCoder: its vastly easier to employ me in some other position than pilot
06:51 AM * Loetmichel has learned some sign language about 30 years back...
06:52 AM Loetmichel: ... man was that fun to greet the class of teens on my way out of the train car...
06:52 AM XXCoder: imange employing interpeter each airplane ride lol
06:52 AM Loetmichel: ... the ones that rode with me in the same train every thursday... and made snide remarks about all the other passengers ;)
06:53 AM Loetmichel: in sign language of course, them being from a school for the deaf ;)
06:55 AM XXCoder: lol
06:58 AM XXCoder: holy fuck. http://www.11alive.com/news/employees-say-theyre-forced-to-work-amid-bed-bug-infestation/451441739
06:59 AM Loetmichel: it was totally worth to learn the basics of sign language to "listen" to their remarks... and of course the looks oon their face when i said goodbye in sign at the end of the year was VERY funny ,)
07:00 AM XXCoder: lol I bet
07:00 AM XXCoder: if chatting in public I always assume someone knows asl and are watching
07:00 AM XXCoder: good assumation because asl is much easier to listen in than speaking
07:01 AM Loetmichel: these were teens
07:02 AM XXCoder: yeah not well known for self-control
07:02 AM Loetmichel: they just learned it themseves i assume. at least they were not aware that "hearing" ppl can read it
07:02 AM Loetmichel: "cool secret language, who will ever know?"
07:02 AM Loetmichel: :-)
07:03 AM XXCoder: theres this term in CS
07:03 AM XXCoder: security though obscurity is not real security
07:03 AM Loetmichel: yes
07:03 AM Loetmichel: its the same on the internet though
07:04 AM Loetmichel: some think they are "anonymus" and start losing all inhibiotions regarding manners and even crimes in some cases
07:05 AM XXCoder: lol yeah
07:05 AM XXCoder: some even think its great to be an asshole that way
09:27 AM IchGucksLive: hi
09:28 AM IchGucksLive: does someone know if i can get a other language at the LIVE DVD without install
10:09 AM CaptHindsight: fast enough for LCNC on the R4 and hardware stepping on the M0+? http://www.samsung.com/semiconductor/minisite/Exynos/w/solution/iot/T200/
10:11 AM CaptHindsight: looks like no GPU included in this model
11:25 AM roycroft: hey folks
11:25 AM roycroft: i'm finding inexpensive tapered lathe mandrels
11:25 AM roycroft: and much more (7-x10x) expensive tapered lathe mandrels wiht sleeves
11:25 AM roycroft: is a sleeve really necessary to hold the work on a mandrel?
11:26 AM roycroft: it seems to me that if the bore is the right size it should just push onto the mandrel and stay in place
11:26 AM roycroft: especially if the big end of the taper is towards the headstock and one is making facing cuts
11:26 AM roycroft: am i wrong? is it a waste of money to get a mandrel without a sleeve?
11:27 AM * JT-Shop tries to understand but is drawing too many variations of the words in my head
11:28 AM roycroft: i have a part that is too big to hold in my chuck
11:28 AM roycroft: i need to turn a spud on it so that i can hold it in the chuck for further turning
11:29 AM roycroft: i want to bore a hole in the center of it (on my milling machine)
11:29 AM roycroft: push it onto a mandrel and turn it between centers on the lathe
11:29 AM roycroft: i can get tapered mandrels
11:30 AM roycroft: as long as my bore is bigger than the narrow end of the mandrel and smaller than the large end of the mandrel i should be able to just push it onto the mandrel and it will hold in place while i'm turning it
11:30 AM JT-Shop: can you just mill the spud into the part
11:31 AM roycroft: i thought this was a simple thing until i started seeing the mandrels with sleeves
11:31 AM roycroft: i don't have a rotary table
11:31 AM roycroft: and the mill is not cnc'ed
11:31 AM roycroft: so it would be difficult to turn the spud on the mill
11:31 AM JT-Shop: can you layout and mill 3 pockets for the jaws to grip on?
11:32 AM JT-Shop: I assume you use a 3 jaw like most
11:32 AM roycroft: for now, yes
11:32 AM roycroft: the part is the backing plate for the 4 jaw i just bought
11:32 AM sync: you can also just superglue a piece of round stock into a hole in your part
11:32 AM sync: and then heat it and remove it after machining
11:32 AM roycroft: i've thought of that
11:32 AM roycroft: i'm not sure it would hold well enough, but i'm probably wrong about that
11:33 AM sync: it holds very well
11:33 AM roycroft: it's an 8" diameter chunk of cast iron
11:33 AM sync: why shouldn't it
11:33 AM sync: just use a reasonably sized piece of stock to glue in
11:33 AM sync: something like 25.4mm or so
11:33 AM roycroft: i was thinking of a mandrel about 1.25" in diameter
11:34 AM roycroft: so we're on the same page as far as size
11:34 AM roycroft: the final bore will be 60mm
11:34 AM roycroft: i could go up to 50mm or so for the mandrel, but that would be a lot more work boring on the mill
11:35 AM roycroft: my lathe has a frankenstein spindle thread - m60x8tpi
11:47 AM roycroft: i suppose if the part doesn't hold well enough on the tapered mandrel i can always super glue it to the mandrel
11:49 AM roycroft: standard taper is 0.0005"/1", and the mandrel is 8" oal, so i should have a good 0.0025" to play with at least, leaving room for the lathe dog
11:50 AM * roycroft can bore that accurately in his sleep on his mill
11:54 AM sync: if you just turned a pin say 5/100mm under and glued it in you can save on the mandrel
11:54 AM sync: it works very well
11:55 AM sync: if you are worried about it coming out use loctite 648
11:56 AM roycroft: i just ordered the mandrel - it was $20 with free shipping
11:56 AM roycroft: hardly worth turning my own for that price
11:56 AM sync: you don't need to turn your own mandrel, just a piece that is round
11:57 AM roycroft: i don't have anything laying around, and even buying a piece of scrap at the steel yard would cost me at least $10
11:57 AM roycroft: plus the time to go find it and buy it
11:59 AM roycroft: i don't mistrust super glue or green loctite, but i also don't know what their limits are
11:59 AM roycroft: i trust your word that they would be fine for this application, but i would rather experiment later on
11:59 AM sync: calculate how good they hold
12:01 PM roycroft: this backing plate blank will weight ~17.5kg before machining
12:02 PM roycroft: and will be spinning at 60rpm, which is as slow as my lathe will go
12:02 PM roycroft: to me that seems like a lot of mass to be spinning around
12:02 PM JT-Shop: how much would it cost to take it to a machine shop that can chuck up >8"
12:02 PM roycroft: i don't know
12:03 PM roycroft: probably $100 at least
12:03 PM roycroft: but that's not the main point
12:03 PM roycroft: i want to do this myself as a learning experience
12:03 PM JT-Shop: and I can understand that too
12:04 PM roycroft: i want to upgrade my 3 jaw eventually as well
12:05 PM roycroft: but by that time i'll have the 4 jaw working, and it will e able to hold a 6" or 8" blank directly, so the mandrel thing won't be necessary
12:05 PM JT-Shop: I never use my 3 jaw chuck any more
12:05 PM sync: I highly doubt that you are able to put more than 471Nm onto your workpiece
12:05 PM roycroft: i also want a collet chuck
12:06 PM sync: that is with a 30mm long glue area
12:06 PM roycroft: and after i get the collet chuck, i may end up using that + the 4 jaw 90+% of the time
12:06 PM JT-Shop: yea I have a 5C collet chuck that fits in my 4 jaw
12:06 PM roycroft: the blank will be 75mm thick
12:06 PM roycroft: so i would have a much longer glue area than that
12:06 PM sync: yeah, but less is sufficient
12:06 PM sync: even 10 would probably be ok
12:07 PM sync: also #yolo
12:07 PM roycroft: i'll see how well friction works
12:07 PM roycroft: and if not it's good to know that superglue can easily hold it
12:08 PM roycroft: jt-shop: i'm not sure yet how i'll mount the collet chuck when i get it
12:08 PM roycroft: i might mount it directly in the headstock taper
12:08 PM roycroft: my spindle bore is big - it's mt 5
12:09 PM roycroft: one of the main reasons i decided to get this lathe
12:09 PM roycroft: it's a rather large spindle bore for a 12x36
12:15 PM JT-Shop: http://gnipsel.com/images/Samson/samson04.jpg
12:17 PM roycroft: yes, that's another option, and if my 4 jaw bore is big enough it might be the way to go
12:18 PM roycroft: it would certainly be the easiest way to mount it
12:18 PM IchGucksLive: hi
12:18 PM roycroft: hallo
12:23 PM IchGucksLive: roycroft: why dident ou use a ready made spinle fix block with cooling rupps
12:25 PM IchGucksLive: roycroft: somthing like that one https://www.sorotec.de/shop/Spindelhalter-f-r-65mm-HFS-Spindeln.html
12:27 PM roycroft: what would that have done for me?
12:31 PM JT-Shop: it could be a nice place to park your dremel???
12:32 PM miss0r: Did someone post a picture of a dumpster just before I joined? :þ
12:34 PM IchGucksLive: miss0r: 23'
12:34 PM miss0r: I'm lost here :)
12:34 PM IchGucksLive: https://www.google.de/search?hl=de&site=imghp&tbm=isch&source=hp&biw=1623&bih=873&q=picture+of+a+dumpster&oq=picture+of+a+dumpster&gs_l=img.3..0i19k1l2.2288.2288.0.3548.1.1.0.0.0.0.89.89.1.1.0....0...1..64.img..0.1.88.kt9rrN2fZS0
12:35 PM miss0r: heh
12:36 PM IchGucksLive: i see lots of green monsters
12:37 PM miss0r: I've been toying with the idea of using a beckhoff PLC (CX1000), which is born with a windows XP embedded, to run linuxcnc. The PLC comes with a dvi/vga output & two usb ports. The problem is, I can't seem to make sense of the NK.bin file, that holds the operating system on a flashcard. I realy can't seem to do anything about that damn file. I've read on beckhoffs own webpage, that some companies run this PLC
12:37 PM miss0r: with linux, but it is not officialy supported, and they will not send me anything.
12:38 PM miss0r: Would any of you guys know about this? :]
12:40 PM IchGucksLive: miss0r: https://github.com/Beckhoff/ADS
12:41 PM IchGucksLive: Beckhoff BIOS API Linux Kernel Driver
12:43 PM miss0r: What I see there, is a software I can use to communicate with a remote beckhoff device from linux.
12:43 PM miss0r: Correct me if i'm wrong here.
12:43 PM miss0r: What I want is to install linux directly on the device
12:43 PM IchGucksLive: https://github.com/Beckhoff/BBAPI
12:44 PM IchGucksLive: this is supposed to do the jop as i read
12:45 PM miss0r: It seems interresting. Reading like a mad man
12:46 PM IchGucksLive: but nowhere it is telling to direct in the plc
12:46 PM IchGucksLive: oly connecting from linux
12:46 PM miss0r: that, and it seems theres no support for cx10xx only cx2xxx and upwards
12:51 PM miss0r: This is a wild goose chase. I looked at this a few years ago.. The urge to use this golden hardware for something comes over me once in a while... it never seems to pay off
12:54 PM IchGucksLive: why going the plc way
12:54 PM miss0r: cheaper(for me anyway) that buying mesa cards
12:54 PM miss0r: and I am collecting stuff for retreofitting my old cnc
12:54 PM miss0r: that, and the hardware quality is very good in these beckhoff units.
12:54 PM IchGucksLive: yeah they are of my country
12:55 PM miss0r: i know. As much as I would like to make a smartass comment about german quality it just won't work :] 1) you won't find it funny & 2) I haven't seen anything out of Germany that is not good quality
12:56 PM IchGucksLive: lots of grazy people here and lots of shit also
12:56 PM miss0r: The same goes for Denmark(where I am from), but it seems we stopped making things back in the '70
12:56 PM miss0r: We use to make some realy realy good surface grinders 'round here. But now its exported to china
12:56 PM IchGucksLive: denmark has a very good performence rate
12:57 PM JT-Shop: I used to visit Denmark to go to the Encotec factory where they build nail machines
12:57 PM IchGucksLive: also a realy high education standard
12:57 PM IchGucksLive: very high speed punches
12:58 PM miss0r: Don't I know it. I've spend 18 years on education... and i'm 'only' an industrial electrician
12:58 PM IchGucksLive: go for mechatroics
12:59 PM miss0r: We actualy had a class called so in highschool/Gymnasium (Not realy the same thing)
01:00 PM IchGucksLive: mow its the makers
01:00 PM IchGucksLive: now
01:00 PM miss0r: yeah. Its what i'm trying to do in my shop here. At my daytime job I rarely do any mechanics
01:01 PM IchGucksLive: thats what the most people asking me need the RED cable man
01:01 PM kyle___: acquired a shop dog this weekend http://i.imgur.com/MUmQFrs.jpg
01:02 PM miss0r: lol
01:02 PM kyle___: got her home and she immediately followed me into the garage to assist me in converting a microwave transformer into a spot welder transformer
01:02 PM IchGucksLive: kyle___: you may blowup yourself one time
01:03 PM kyle___: so far so good
01:03 PM IchGucksLive: with sall this funny changes
01:03 PM kyle___: this microwave was actually really nicely designed, HV capacitor was tucked far away with a big beefy bleeder resistor
01:03 PM kyle___: but it hadn't been used in 6 months either
01:04 PM kyle___: still discharged it of course, that's too scary for me
01:04 PM miss0r: All my caps I have are bolted closed when not in use. I'm a sissy when it comes to caps
01:04 PM IchGucksLive: im off bad news someone has pased away in town need to open the graveyard cooler
01:04 PM IchGucksLive: BYE
01:05 PM miss0r: WTF is a graveyard cooler?
01:05 PM roycroft: morgue, i presume
01:05 PM miss0r: ahh. indeed
01:06 PM roycroft: i did not know that ichguckslive is also a coroner
01:06 PM LeelooMinai: ...
01:06 PM roycroft: he wears many hats, it appears
01:07 PM miss0r: Yeah.. speaking of bad news - I had too much chili earlier... I will see you another time
01:07 PM * miss0r runs off
01:27 PM phipli: evening
01:31 PM JT-Shop: yo
01:33 PM phipli: How goes?
01:44 PM JT-Shop: got the stand for the water bucket made just need to put some feet on it so I can nail it down to the ground
01:44 PM JT-Shop: don't need chickens knocking it over lol
01:47 PM phipli: :)
01:48 PM phipli: We have this sort of thing : https://www.amazon.co.uk/dp/B005J18DWC/ref=twister_B00GHJPBU2?_encoding=UTF8&psc=1
01:52 PM LeelooMinai: Not sure how it works...
01:53 PM LeelooMinai: How does it regulate so the water does not spill?
01:56 PM JT-Shop: smd's
01:57 PM phipli: LeelooMinai: like lifting a glass upside-down from the kitchen sink. Basically like magic
01:59 PM LeelooMinai: So it's just as it is on the picture? Nothing special inside? Just negative pressure?
01:59 PM phipli: there is a trough at the bottom with a small outlet into the centre
02:00 PM phipli: when the trough water level drops lower than the opening, a bit of water runs out
02:00 PM LeelooMinai: Hmm, weird - never saw something like that for cats/dogs and would think that people would use it.
02:01 PM renesis: youve never seen a water dispenser for cats?
02:01 PM JT-Shop: we have two for the cat, one for water and one for food
02:01 PM renesis: https://www.amazon.com/Plastic-Feeder-Water-Dispenser-Feeding/dp/B072KH95MK/ref=sr_1_4?ie=UTF8&qid=1498501858&sr=8-4&keywords=cat+2+liter+water
02:01 PM LeelooMinai: renesis: No - just bowls:) But ok, I guess I may have missed them then.
02:02 PM phipli: yeah we have something similar for the chicken food too
02:02 PM JT-Shop: phipli: I have one like this https://www.ruralking.com/miller-mfg-1-gallon-plastic-poultry-chicken-fountain-jar-7506.html but the chickens made a mess in it
02:02 PM phipli: but with openings all around instead of just one side
02:02 PM phipli: JT-Shop: you can hang ours up
02:02 PM phipli: and need to
02:03 PM phipli: they're very good at pooing in things
02:04 PM JT-Shop: aye, I learned that right off lol
02:04 PM LeelooMinai: A, ok, this is good explanation: https://www.quora.com/How-do-mineral-water-dispensers-work
02:05 PM phipli: http://citygirlfarming.com/2013/11/09/diy-chicken-water-heater-less-than-four-minutes-and-four-dollars/
02:18 PM JT-Shop: cool
02:27 PM phipli: I have a bucket with (some) sand in it, with a bulb suspended in a disk above it as a heater for them
02:27 PM phipli: but it hasn't really been needed yet.
02:27 PM phipli: take the water in at night
02:27 PM phipli: thats about it
02:48 PM JT-Shop: I put a hook in the center of the coop to hang a heat lamp if needed
03:01 PM narogon: hi
03:01 PM narogon: does anybody know how use a index pulse without a pid component?
03:02 PM JT-Shop: for?
03:03 PM narogon: for homing
03:03 PM narogon: I have servos with ethercat
03:03 PM narogon: that have a index pin
03:04 PM narogon: i found a index-enable pin but i thought it isn't what i need
03:05 PM JT-Shop: http://linuxcnc.org/docs/2.7/html/config/ini-homing.html#_home_use_index
03:06 PM JT-Shop: been some chatter on the mailing list about homing to index without a pid and it doesn't seem possible iirc but I may be wrong too
03:06 PM narogon: i found those chatter
03:06 PM pcw_mesa: what happens to the Ethercat drives position data when index occurs?
03:06 PM narogon: nothing
03:07 PM narogon: it remains the same
03:07 PM pcw_mesa: is there a latched count at index available?
03:08 PM narogon: no
03:08 PM narogon: I could do the homing procedure using the servos
03:08 PM narogon: and they reset the position after home
03:08 PM narogon: but I want to use the linuxcnc method
03:09 PM pcw_mesa: Sounds like you would have to use the drives homing since they dont provide LinuxCNC with the info needed to home to index
03:12 PM narogon: they send a index pulse
03:12 PM narogon: 1 time per rotation
03:12 PM narogon: what more do linuxcnc need?
03:12 PM pcw_mesa: You might be able to do it by a simulated encoder component that handles index enable
03:12 PM pcw_mesa: but the final move wouldl have to be slow since it neither clears the position or latches the position at index
03:13 PM narogon: if you go ahead the index pulse
03:13 PM narogon: and return
03:13 PM narogon: it send a index again
03:14 PM narogon: is it needed that the position reset to 0 when index occurs?
03:15 PM pcw_mesa: its expected of the encoder component
03:15 PM pcw_mesa: (if index enable is true)
03:16 PM narogon: so, it is impossible to use that home method
03:17 PM narogon: or i have to create a component
03:17 PM narogon: that insert an offset
03:17 PM narogon: to possition in the moment of the index edge?
03:18 PM pcw_mesa: so on the home to index move, linuxcnc set index-enable true, telling the encoder logic to arm its index detection hardware/software
03:18 PM pcw_mesa: Then when the encoder hardware/software detects an index event it clears index enable and clears the encoder position
03:19 PM narogon: i would reprogram my ethercat component to achieve this
03:19 PM pcw_mesa: clearing the encoder position is in someways a mistake (and needs some ugly workarounds in motion and PID) but many hardware encoders counter work this way
03:20 PM narogon: maybe would be interesting to include this in linuxcnc
03:21 PM pcw_mesa: I think you could make a component the does the index enable logic/offsetting
03:21 PM narogon: yes yes
03:21 PM narogon: i will do in the own ethercat component
03:23 PM pcw_mesa: it would still suffer from the issue that you could not do the home to index move at faster than 1 count/servo period without losing position accuracy
03:23 PM pcw_mesa: but the home to index move is generally very small so that may not matter
03:32 PM narogon: thanks for all
03:32 PM narogon: i would try and tell here the results
03:53 PM m0n5t3r: does anyone know where touchy stores its preferences / saved values / whatever?
03:55 PM cradek: m0n5t3r: hi, what problem are you trying to solve?
03:55 PM m0n5t3r: I'm figuring things out and I spent a few hours trying to understand why my feeds were limited to 220 mm/min; then I found the "mv" button, which seems to set some speed limit
03:56 PM m0n5t3r: ... and it's nowhere to be found in documentation
03:56 PM cradek: your ini file sets your machine's max velocity, one for each axis
03:57 PM m0n5t3r: yeah, I had already set that to 100 mm/s, timings, etc were fine
03:57 PM cradek: mv is max velocity - you can reduce the max velocity for jogging slower, or running a program carefully for the first time
03:59 PM m0n5t3r: I figured that out (minus what the name means) :)
04:00 PM m0n5t3r: I was wondering if the value is stored somewhere or I'll have to turn the encoder until I'm blue in the face after reboot
04:00 PM cradek: I don't understand the question
04:00 PM m0n5t3r: some values seem to survive program restarts and I was curious where they are stored
04:01 PM cradek: yes everything on the options screen is supposed to be persistent
04:01 PM cradek: it writes to a file ... somewhere
04:01 PM cradek: probably your home directory
04:02 PM m0n5t3r: ah, found it... .touchy_preferences
04:03 PM m0n5t3r: I thought it would be something in the configuration directory or ~/.config, didn't think to look in the home dir :(
04:04 PM m0n5t3r: thanks

04:36 PM roycroft: so i think i've sorted out the mandrel thing
04:36 PM roycroft: the ones with sleeves are wide-range expanding mandrels
04:36 PM roycroft: which i don't need
04:36 PM roycroft: the ones without the sleeves are made for an exact diameter
04:42 PM Deejay: gn8
05:27 PM JT-Shop: yea I have eoffsets working now to tune it some
09:54 PM MacGalempsy: hello
10:03 PM BeachBumPete: hey mac
10:14 PM Crom: what a busy 3 days!
10:15 PM Crom: Saturday Bar Z summer Bash 2017, Sunday - Last day of Koronaburg Faire - Today doctors appointments..
10:18 PM MacGalempsy: sorry got busy
10:18 PM Crom: 40+C everyday
10:20 PM MacGalempsy: sounds pleasant
10:43 PM LeelooMinai: Hmm, I need to MacGaver a number clamps for door frame that somehow can clamp without having counter-clamp on the other side...
10:45 PM LeelooMinai: Maybe there are clamps like that, but I just don't know the name - like C-clamp more or less, but they would have also a way to clamp one side perpendicular to the C-clamp main axis.
10:46 PM Crom: frame clamps
10:46 PM Crom: miter clamps..
10:47 PM LeelooMinai: Framing clamps comes up with clamps that are for corners of frames - I have one like that, but that's not what I mean.
10:48 PM LeelooMinai: O, I think I found them. Seems "edging clamp" is the name.
10:48 PM LeelooMinai: http://www.newwoodworker.com/reviews/graphics/photos/tools/besyedgeclmprvu/3screw250.jpg
10:48 PM LeelooMinai: Right, that's how I imagined them.
10:49 PM Crom: oh those.. I have 2, we call them edge clamps
10:49 PM Crom: edging.. close enough
