12:21 AM IchGucksLive: ing from a sunny summer day in germany
12:27 AM IchGucksLive: im off 2 garden
12:46 AM pink_vampire: hi all
12:52 AM fragalot: hi pink_vampire
12:52 AM pink_vampire: hi fragalot!
12:53 AM pink_vampire: i just put the last nut in my lathe
01:14 AM Deejay: moin
01:16 AM pink_vampire: hi Deejay
01:33 AM gloops: hottest april 19th EVER, only a month ago we complaining about snow
01:34 AM pink_vampire: here is cold
01:34 AM gloops: 28 C today
01:34 AM CaptHindsight: snowing here right now
01:34 AM pink_vampire: we got a bit of slashy snow yesterday
01:35 AM CaptHindsight: so it's probably all melted by now
01:36 AM pink_vampire: someone here worked before with 4 jaw independent chuck?
01:36 AM pink_vampire: CaptHindsight: gloops^
01:41 AM gloops: yes, having problems?
01:41 AM pink_vampire: yeah
01:42 AM gloops: how so?
01:42 AM pink_vampire: the lowest i can dial a part is 0.001 in
01:42 AM pink_vampire: i can't d o better then that
01:43 AM gloops: when setting it up in the chuck?
01:43 AM pink_vampire: and I'm using ground drill rod for the test
01:44 AM gloops: there arent many mechanical reasons a 4 jaw cant get something central
01:45 AM gloops: only spindle out of true, or chuck backplate maybe
01:46 AM pink_vampire: i think is something with my technique
01:46 AM gloops: so you are working on 2 planes, 2 sets of opposing jaws
01:47 AM gloops: to move on one plane, you have to loosen one jaw, and push with the opposite jaw
01:47 AM pink_vampire: correct
01:47 AM pink_vampire: this is what i'm doing
01:47 AM gloops: dont have the other jaws really tight or the work wont move
01:48 AM selroc: hi
01:48 AM gloops: i tend to tighten up when im really close, gradually
01:48 AM gloops: hello selroc
01:48 AM pink_vampire: it became very hard to controll it
01:48 AM pink_vampire: hi selroc
01:49 AM selroc: hi
01:50 AM gloops: his the measurement further away from the chuck - same or worse, or a lot worse
01:50 AM gloops: how is the measurement
01:51 AM gloops: and also, try the dial on the chuck itself, and the chuck backplate
01:52 AM pink_vampire: there is no back plate on the chuck
01:53 AM gloops: hmm
01:54 AM gloops: if the chuck is not square/parallel with the spindle, the drill rod will be at an angle
01:54 AM gloops: although i dont think that is your problem
01:55 AM selroc: is this compatible with linuxcnc https://www.ebay.it/itm/ECO-Wireless-USB-CNC-Elettronica-Volantino-Hand-Wheel-for-Mach3-Control-System/391858672832?hash=item5b3c98d4c0:g:XO0AAOSwa~BYds67 ?
01:55 AM gloops: probably some practice required? very small adjustments
01:56 AM pink_vampire: i took a picture
01:57 AM pink_vampire: gloops: https://i.imgur.com/GaB5dDf.jpg
01:58 AM pink_vampire: selroc: I have no idea why you need it
01:58 AM gloops: thats a 4 jaw chuck?
01:58 AM pink_vampire: yes
01:58 AM selroc: to control cnc by hand
01:59 AM pink_vampire: selroc: https://i.imgur.com/RXNRYtX.png this is what I'm use
01:59 AM gloops: pink_vampire how do you adjust the jaws independently ?
02:00 AM pink_vampire: correct
02:02 AM selroc: nice keyboard
02:03 AM pink_vampire: it's a full keyboard with a mouse, so you can use in in the mdi
02:04 AM pink_vampire: there is no F keys, so you will need to edit the axis.py if i remember right..
02:04 AM pink_vampire: (it was long time ago)
02:05 AM selroc: I tend to use gmoccapy but axis is nice too :-)
02:06 AM pink_vampire: I have no idea how to set it up
02:07 AM selroc: no worry, I will find out
02:09 AM pink_vampire: othe then probing macros and i did a lot of them I'm only use it as the most basic way (i try to make the interface as simple as possible to avoid real time issues in long codes)
02:20 AM selroc: I guess one has to edit config files and configure HAL\
02:21 AM selroc: that's the usual way :-)
02:21 AM gloops: someone did that the other week, cant remember his nick now
02:21 AM gloops: it is doable
02:21 AM gloops: might be examples on the forum
02:23 AM pink_vampire: is there better platform then irc? to share images and videos
02:24 AM selroc: I don't know, maybe Instagram ?
02:24 AM pink_vampire: you can't chat on Instagram
02:25 AM gloops: facebook
02:25 AM selroc: probably you can paste links here
02:27 AM pink_vampire: I'm using whatsapp
02:28 AM pink_vampire: but there is no linuxcnc group that i know about
02:30 AM selroc: long time ago we had a program to share chat and video
02:31 AM pink_vampire: skype?
02:33 AM selroc: no it was called cu-seeme
02:33 AM pink_vampire: https://en.wikipedia.org/wiki/CU-SeeMe#/media/File:CU-Schools.GIF
02:34 AM selroc: yes
02:34 AM pink_vampire: that is old
02:35 AM selroc: yes but I still have to see a program like this where you can videoconference and chat
02:35 AM selroc: skype , AFAIK is only for one video at a time
02:36 AM pink_vampire: you can do video group in skype
02:39 AM selroc: ah
02:41 AM pink_vampire: whatsapp
02:42 AM selroc: well well we can create a linuxcnc group in whatsapp
02:42 AM pink_vampire: but the cool thing about whatsapp is the option to send short videos just by holding the camera button
02:43 AM pink_vampire: i have no idea if people here use whatsapp
02:45 AM selroc: I use it a little
03:04 AM pink_vampire: selroc: i made one
03:07 AM Loetmichel: mope, never made an account, to the dismay of my wife ,)
03:08 AM Loetmichel: -m+n
03:10 AM pink_vampire: lol
03:41 AM pink_vampire: I did it!!
03:44 AM pink_vampire: dial to less then half a thou!
04:05 AM pink_vampire: XXCoder: ?
04:09 AM The_Ball is now known as Guest81207
04:09 AM phipli: gloops : the window place hasn't heard from him
04:09 AM phipli: they've said they'll give him a call on his mobile and drop me an email
04:10 AM phipli: although gloops isn't online...
04:10 AM phipli: never mind
04:13 AM Guest81207 is now known as The_Ball1
04:24 AM XXCoder: pink_vampire: that is very good! :)
04:47 AM jthornton: morning
04:49 AM jthornton: phipli: morning
04:52 AM XXCoder: hey jt
04:55 AM jthornton: got started putting up the hot wires on the fence http://gnipsel.com/images/chickens/fence/charger.jpg
04:55 AM jthornton: http://gnipsel.com/images/chickens/fence/fence-01.jpg
04:55 AM jthornton: http://gnipsel.com/images/chickens/fence/fence-02.jpg
04:57 AM XXCoder: protection from animals entering eh
04:58 AM jthornton: upping my defense after finding an opossum inside the run the other day.
05:00 AM XXCoder: geez
05:03 AM phipli: morning jthornton
05:04 AM phipli: have you had more trouble, or is this just further work on fortclux
05:04 AM jthornton: when I'm done with the hot wires the only threat will be from above
05:04 AM jthornton: got up one morning and saw a opossum eating out of the feeder on camera
05:05 AM phipli: some light netting might be enough for that (above)
05:05 AM jthornton: I think my risk is minimal because of all the trees and structures around the chicken yard and much easier pickings next door
05:06 AM phipli: http://www.possumfarming.com/Pics1/possum%204.jpg
05:06 AM jthornton: I also watched a hawk fly right through some thick trees the other day by folding up it's wings to fly through small holes too
05:06 AM phipli: do you think he's noticed?
05:07 AM jthornton: no he flew a bit to the north of the chicken yard
05:08 AM XXCoder: interesting
05:08 AM jthornton: the hawks do know my neighbor has free ranging chickens
05:12 AM phipli: what type of hawk?
05:13 AM jthornton: we have red tailed hawks mostly
05:13 AM The_Ball1 is now known as The_Ball
05:13 AM jthornton: https://pages.wustl.edu/mnh/raptors-missouri
05:14 AM phipli: back home red kites were our main bird of prey
05:14 AM phipli: bigger, but didn't cause issues regarding the chickens
05:15 AM phipli: https://en.wikipedia.org/wiki/Red_kite
05:15 AM jthornton: we have a lot of black vultures and a few bald eagles
05:15 AM phipli: they're meant to be rare, but I grew up in their last holdout and main recovery location
05:15 AM phipli: so you'd see loads (there was someone that fed them, and you'd see 20 at a time as you drove past)
05:16 AM jthornton: bald eagles?
05:17 AM phipli: no, red kites
05:17 AM phipli: we also have buzzards https://en.wikipedia.org/wiki/Common_buzzard
05:18 AM phipli: and a few Kestrels, but not so many https://en.wikipedia.org/wiki/Common_kestrel
05:18 AM phipli: there is a Sparrow Hawk at my grandparents house, and an Osprey nest in the middle of town here (they like towers)
05:18 AM phipli: but back home it is all buzzards and kites
05:19 AM jthornton: we have Mississippi Kite in the summer time
05:20 AM jthornton: most of the time you only see raptors along side farmers fields but one summer a red tailed hawk couple built a nest in my front yard which is mostly forest
05:22 AM phipli: You see a lot of buzzards because they're lazy
05:22 AM phipli: they sit on top of telegraph poles next to the road watching the fields for food
05:23 AM phipli: its nice to see them
05:23 AM phipli: we nearly wiped all the big birds of prey out here
05:24 AM jthornton: from over hunting them?
05:24 AM phipli: "hunting" is the wrong word
05:24 AM phipli: shooting on sight
05:24 AM jthornton: perceived as a pest then
05:25 AM phipli: farmers blamed them for the death of lambs etc (because if there was a dead lamb, they'd investigate)
05:25 AM phipli: even after they were very rare, people wouldn't stop shooting them
05:25 AM phipli: the last ones (strangely) survived in marshy areas where you couldn't farm
05:26 AM jthornton: a neighbor saw a bald eagle eating on a deer carcass near here the other day
05:26 AM jthornton: out of sight out of mind
05:27 AM phipli: they're impressive birds : http://wildlifearticles.co.uk/wp-content/uploads/2016/09/0815.IMG_8561.jpg
05:27 AM jthornton: we have daily buzzard fly overs
05:28 AM phipli: 70 inch wingspan
05:28 AM jthornton: wow that is a big bird
05:29 AM phipli: they are - don't look it in the sky
05:29 AM phipli: but you see a dead one and they're HUGE
05:30 AM jthornton: our turkey vultures have a 70" wingspan
05:32 AM jthornton: they ride the uplifts in the air and circle around a thermal to gain height
05:33 AM jthornton: did you ever install the auto chicken door?
05:33 AM phipli: :( no
05:33 AM phipli: I'm a terrible person
05:33 AM phipli: I have to admit I'm so nervous about killing a chicken with it
05:34 AM phipli: plus I /really/ struggle to fit in the coop
05:34 AM phipli: (read, almost can't)
05:34 AM jthornton: my lock kept failing so I took it off, I need to get an open frame lock so I can have a micro switch to sense that it's open
05:34 AM jthornton: time to build a bigger coop
05:35 AM phipli: I'm not very good at woodwork
05:35 AM jthornton: have you see a hoop coop?
05:35 AM phipli: but the neighbour does gardensheds / dovecotes
05:36 AM phipli: sensible design
05:36 AM jthornton: and super easy to make, do they have cattle panels over there?
05:37 AM phipli: I'm sure
05:37 AM phipli: possibly under another name
05:37 AM phipli: these? https://www.sure-green.com/products/welded-wire-mesh/welded-wire-mesh-panels.php?product=778&utm_source=adrac&utm_medium=shopping&gclid=EAIaIQobChMI5MaBm5LG2gIVTIwZCh12JgA2EAkYASABEgKdC_D_BwE
05:38 AM jthornton: https://www.tractorsupply.com/tsc/product/feedlot-panel-cattle-16-ft-l-x-50-in-h
05:38 AM jthornton: ours are 16' long and 50" wide with larger spacing
05:40 AM phipli: the ones I shared are 8'x4'
05:40 AM phipli: 16' would be tricky to deliver :)
05:40 AM phipli: you'd need a lorry
05:41 AM jthornton: https://www.youtube.com/watch?v=aMlX54LTLjE
05:44 AM phipli: https://i.pinimg.com/originals/7b/8e/ae/7b8eae7c8f6cd409ecf2cda166abe905.jpg
05:44 AM phipli: I have one of those (not that it is on the road)
05:44 AM Tom_L: 32F
05:44 AM phipli: while I admit it has advantages for tall loads...
05:44 AM phipli: (I've moved ladders with it)
05:45 AM phipli: Tom_L, lovely day here
05:45 AM phipli: best weather we've had so far this year
05:45 AM phipli: 22*C
05:45 AM phipli: 71.6F ?
05:46 AM jthornton: 44°F here and clear with a high of 56°F looks like a good day to split firewood
05:47 AM jthornton: what kind of car is that?
05:47 AM phipli: Mk1 MX5
05:47 AM phipli: soap bar
05:48 AM phipli: My first car
05:48 AM jthornton: ah mazda
05:48 AM phipli: it is deteriorating, but I'm struggling to persuade myself it get rid of it
05:48 AM phipli: put too much effort into working on it
05:48 AM phipli: and too much money into parts that I wont get back
05:48 AM phipli: considering turning it into a kit car
05:49 AM jthornton: my first car https://www.hemmings.com/blog/2017/05/28/hemmings-find-of-the-day-1957-volkswagen-beetle/
05:49 AM phipli: grew up with bugs :)
05:50 AM phipli: had two split screen campers and a couple of beetles at various points when I was a kid
05:50 AM phipli: then the campers became worth money and fuel got expensive
05:50 AM phipli: so my folks sold them to pay for stuff to start sorting out the house
05:50 AM phipli: 5 air cooled engines in the shed back home still though
05:51 AM phipli: we have different bumpers on ours though (beetles) and the indicators are on top of the front wings
05:52 AM phipli: more like this : http://car-from-uk.com/ebay/carphotos/full/ebay25086.jpg
05:53 AM jthornton: mine had the turn signals on top of the fenders but had the bumper like the black one
05:54 AM jthornton: tiny back window with the wolfburg castle emblem on the bonnet
05:55 AM phipli: and a de-mister that misted the window?
05:55 AM phipli: jthornton, one of ours had the a wolfburg castle
05:55 AM phipli: my dad used to build dune buggies out of scrap ones
05:55 AM jthornton: IIRC all it had was wipers that sometimes worked
05:56 AM phipli: hence so many bits laying around
06:02 AM jthornton: makes sense, I converted my 66 to a baja bug (cut of rear and open engine)
06:03 AM jthornton: cut off even
06:04 AM phipli: http://elephantandchicken.co.uk/buggies/038.jpg
06:05 AM jthornton: cool
06:05 AM pink_vampire: phipli: is that you?
06:07 AM phipli: nope
06:07 AM phipli: too long ago
06:07 AM phipli: passenger is my uncle
06:07 AM phipli: driver is my dad
06:08 AM phipli: that is about 1985
06:11 AM jthornton: I was working in west Africa around that time
06:13 AM fragalot: 'llo
06:14 AM jthornton: heh
06:18 AM phipli: jthornton, http://elephantandchicken.co.uk/buggies/index.html
06:19 AM pink_vampire: we made a group for linux cnc and machining in whatsapp, someone what to join?
06:19 AM phipli: I'm in exactly one of those photos
06:20 AM phipli: pink_vampire, I don't whatsapp, much to the frustration of my peers
06:20 AM jthornton: the one with the motorcycle doing a wheelie?
06:21 AM phipli: thats my brother :) I've never had blonde hair
06:21 AM pink_vampire: phipli: you can use it on the computer as well
06:21 AM phipli: jthornton, 012.jpg
06:21 AM phipli: the face next to the air cleaner
06:24 AM jthornton: didn't see you till I zoomed in
06:25 AM jthornton: hmmm sunrise time to let the pullets out
06:25 AM phipli: lunch time
06:43 AM Beachbumpete1: Good Morning LinuxCNC
06:43 AM jthornton: morning Pete
06:54 AM pink_vampire: https://www.facebook.com/machinistmemes/
06:57 AM Beachbumpete1: Hey JT

06:59 AM fragalot: CaptHindsight: ^
07:00 AM SpeedEvil: phipli: yay
07:00 AM jthornton: phipli: good to hear he is ok
07:00 AM SpeedEvil: :)
07:00 AM phipli: he walked through the door while the guy I'd contacted was replying to me saying his hadn't answered his phone
07:01 AM pink_vampire: https://scontent-lga3-1.xx.fbcdn.net/v/t1.0-9/10487331_563360523769162_4944955873208809409_n.jpg?_nc_cat=0&oh=b3018795c678be21cdc1684ed8ea1181&oe=5B6A0364

07:17 AM pink_vampire: https://scontent-lga3-1.xx.fbcdn.net/v/t1.0-9/11148593_10152922109623720_7680360633779729993_n.jpg?_nc_cat=0&oh=93c30c556e570ee46d7efaca0896134d&oe=5B63A636
07:18 AM pink_vampire: sooo true!!
07:38 AM Beachbumpete1: hehe
07:38 AM gregcnc_: https://www.instagram.com/p/BhvgLOIFWSg/
07:39 AM pink_vampire: no no
07:39 AM pink_vampire: lathe and a mill
07:39 AM pink_vampire: or even better swiss and mill turn
07:40 AM gregcnc_: you have to have parts to make first
07:40 AM pink_vampire: i don't need to have parts to make to want a swiss machine
07:44 AM gregcnc_: why a swiss? how many million parts are you making?
07:47 AM pink_vampire: is not about that, I just love the way they work
07:51 AM pink_vampire: https://scontent-lga3-1.xx.fbcdn.net/v/t1.0-9/10355013_10153012966872786_7366938549281341914_n.jpg?_nc_cat=0&oh=5350e6f9790bd8273bd5324366715d89&oe=5B63878E
07:51 AM gregcnc_: perfect
07:58 AM Beachbumpete1: damn thats ghetto fab
08:09 AM Loetmichel: *muhaha* i like customers with a "vision"... remember the point of sales PC i made a prototype a while ago? -> http://www.cyrom.org/palbum/main.php?g2_itemId=16956&g2_imageViewsIndex=1 ... now the customer wants a version for desk, a version to moint on a vesa100 on the wall with variable display angle, a version without display in a 19" 1U rack enclosure. and all of them passive cooled AND
08:09 AM Loetmichel: mil 810 shock and vibration proof... and of course without any additional development cost ;)
08:11 AM pink_vampire: Loetmichel: sounds legit to me
08:20 AM pink_vampire: https://www.facebook.com/machinistmemes/photos/a.464426910329191.1073741828.464406080331274/531950200243528/?type=3&theater

09:30 AM gloops: hot
09:30 AM jdh: anyone use abb irb120?
09:37 AM IchGucksLive: hi
09:49 AM IchGucksLive: hi makerman
10:02 AM pcw_home: phipli: "archivist is fine, just busy" Glad to hear it, I'm such a Gloomy Gus thinking the worse...
10:08 AM hazzy-dev: That is great news about archivist!
10:09 AM Tom_L: doesn't he know he's supposed to check in periodically???
10:09 AM Tom_L: after all ... it's irc!
10:10 AM Loetmichel: hihi, boss wants to fly an 100" TFT to do some measurements vertically... problem: 400++lbs... solution: $me drives to the home improvement shop and buys some snap hooks and two 230kg pulley blocks... done. (hopefully those M8 8,8 screws in the concrete ceiling wil hold that monster ;) --> http://www.cyrom.org/palbum/main.php?g2_itemId=17073&g2_imageViewsIndex=1
10:13 AM Tom_L: just don't stand under it
10:14 AM Loetmichel: Tom_L: at 200kg TV i will not. EVER. :)
10:14 AM Tom_L: are the hook points on a swivel? i may have added across brace near the blocks
10:15 AM Tom_L: so they pull straight down instead of at an angle
10:15 AM Tom_L: some is hidden by the flourescents
10:17 AM Loetmichel: they are screwed to the cabnle tray
10:17 AM Loetmichel: that acts as a cross brace
10:17 AM Loetmichel: hopefully
10:17 AM Tom_L: fair nuf
10:17 AM Tom_L: that or you'll have a nice bbq when the lights come down
10:19 AM Tom_L: at an old job once a forklift driver hit the 3 overhead 3" ish pipes holding the 3 phase for the whole plant
10:19 AM Tom_L: we got off early that day
10:32 AM SpeedEvil: Did he get a nice instant tan?
10:33 AM pink_vampire: any idea how to remove JT2 taper from a 40 years old drill chuck?
10:34 AM SpeedEvil: I suppose angle grinder is cheating?
10:35 AM SpeedEvil: Is itactually a jacobs?
10:35 AM SpeedEvil: diagrams should be readily available, and I vaguely recall youtube vids on the subject
10:37 AM gloops: you need about 20 tonne psi shock loading
10:38 AM gloops: sorry
10:38 AM gloops: 20 tonne p/i
10:40 AM pink_vampire: mmm
10:41 AM gloops: only one tool can do that, well there are others but theyre usually too sharp
10:44 AM rmu: pink_vampire: put the shaft in liquid nitrogen
10:46 AM pink_vampire: map torch didn't work

10:50 AM selroc: hi pink_vampire
10:50 AM pink_vampire: hi selroc
10:56 AM pink_vampire: gloops: i did the drilling
10:57 AM pink_vampire: and i'm trying to hammer the arbor
10:58 AM gregcnc_: wedges
10:59 AM gloops: no retaining collar or anything like that?
11:02 AM gloops: wedges are the other way of asserting massive force
11:03 AM gloops: ive tried all sorts of stuff, warming up, oiling, warming up again to try and get the oil to penetrate, i think with really stuck things its just a combination of whacking, prising, wedging, oil etc, just shifts in the end
11:03 AM Loetmichel: btw: the other side of the TV with boss measuring EMI...-> http://www.cyrom.org/palbum/main.php?g2_itemId=17076&g2_imageViewsIndex=1
11:13 AM pink_vampire: when you don't have a press - machinist vise!
11:16 AM jthornton: ah well lunch minute is over with...
11:20 AM pink_vampire: and after all that, the jacobs tapers are different size!!!!!!
11:23 AM gloops: is this for tailstock?
11:23 AM gloops: you will have a jacobs on one side and a morse on the other
11:25 AM pink_vampire: gloops: correct
11:25 AM hazzy-dev: My nephews flushed the breaks for me yesterday: https://i.imgur.com/ZAVD0Ef.jpg
11:25 AM hazzy-dev: I did not think they were actually going to be able to do it, but they did, and they did a decent job too
11:25 AM hazzy-dev: I had to give them a hand with some tight lugs and pumping the jack handle for the rear, but they did the rest pretty much on their own
11:26 AM gloops: nice motor hazzy
11:28 AM phipli: hey gloops
11:28 AM hazzy-dev: gloops: Thanks! Needs a paint job ...
11:28 AM gloops: hi phipli
11:29 AM phipli: just pm'd you the message I got back after speaking to the window place
11:29 AM phipli: archivist is fine
11:30 AM gloops: good news, thanks for finding out phipli
11:30 AM phipli: no problem
11:31 AM phipli: scary how much you can find out about someone on the internet
11:32 AM phipli: also, we need a bot that does "seen"
11:32 AM phipli: and leaves messages for people
11:32 AM gloops: yeah, tbh im not really comfortable looking peoples personal info up
11:32 AM phipli: there are some standard systems on github
11:33 AM phipli: gloops, hopefully the new eu laws on privacy will make it a bit less easy to do
11:33 AM phipli: pros and cons - wouldn't have been able to do what we did
11:33 AM phipli: but it is creepy that you can find someone's name, address, phone number and associated businesses with a half hour of digging
11:34 AM gloops: well, was just off out, but bbl
11:34 AM phipli: <waves>
11:35 AM skunkworks: so what is the story?
11:35 AM skunkworks: is he ok?
11:35 AM Beachbumpete1: mMMMMmMMM lunchtime
11:36 AM fragalot: Hi
11:36 AM fragalot: 28°C today >.<
11:37 AM Beachbumpete1: about the same here ;)
11:37 AM Rab: Nice and balmy.
11:37 AM fragalot: moist too
11:37 AM hazzy-dev: skunkworks: Apparently archivist is fine, just busy
11:37 AM Beachbumpete1: Nice and Nice
11:37 AM Beachbumpete1: Oh really you guys found him?
11:39 AM cradek: yay :-)
11:39 AM Beachbumpete1: \O/
11:41 AM fragalot: https://www.youtube.com/watch?v=kSuaykdvl4I

11:54 AM IchGucksLive: super summer here
11:55 AM fragalot: yup
11:55 AM IchGucksLive: first naked walker
11:55 AM IchGucksLive: and alot of students female on the bathlake
11:56 AM IchGucksLive: so we call the winter OFFLINE
11:56 AM IchGucksLive: someone in oklahoma at the wildfirer front
11:57 AM IchGucksLive: we had sirence also today but knowone knowes anything
11:57 AM Tom_L: ks has wildfires too
11:57 AM Beachbumpete1: WOW that guy is serious
11:58 AM fragalot: Beachbumpete1: colin?
11:58 AM IchGucksLive: KS kansas
11:59 AM Tom_L: http://www.kake.com/story/37989470/crews-continue-monitoring-wildfires
11:59 AM Beachbumpete1: hell yeaH
11:59 AM Tom_L: gonna be a hot time in the ole town tonight...
12:00 PM fragalot: Beachbumpete1: yeah he's gone from relatively awesome to insanely awesome :)
12:01 PM Beachbumpete1: my kinda maniac ;)
12:01 PM IchGucksLive: i shoudt do so 2
12:01 PM IchGucksLive: people are buying FAKE brigs as always
12:01 PM IchGucksLive: and connecting as scheme F
12:01 PM IchGucksLive: not even reading any pint on the controler or driver
12:02 PM IchGucksLive: mailing nothing workes on your advice
12:02 PM IchGucksLive: with ground to 5V
12:02 PM IchGucksLive: and 5V to Gnd
12:03 PM IchGucksLive: BEST is VCC / VDD to GND and 36V to Gnd
12:03 PM IchGucksLive: the simple M brigs will just smoke
12:04 PM IchGucksLive: Tellimg me i put the red cable inside
12:05 PM IchGucksLive: 10.000 sold mashines a week is getting a nightmare on a YT chennel advicing people
12:05 PM gregcnc_: 10,000?
12:06 PM IchGucksLive: as europ sellers claim
12:06 PM IchGucksLive: i think it is even more on printers cheep as they where
12:06 PM IchGucksLive: also the lasers from europ internal stors are sold out as they are presented
12:07 PM IchGucksLive: I Myself tried to order the BIG N24 4Nm
12:07 PM IchGucksLive: he told me new stock on monday
12:07 PM IchGucksLive: as he where wright
12:07 PM gregcnc_: don't the sellers support the equipment?
12:08 PM IchGucksLive: on wendsday oinly 2 left as 260 sold last 24Hours
12:08 PM IchGucksLive: gregcnc_, there is no control software so many dont like m3
12:08 PM IchGucksLive: or even reprap rebuilds
12:09 PM gregcnc_: ah, wouldn't a website be more efficient?
12:09 PM IchGucksLive: and as we now heding towards 1mio clicks it is on me
12:09 PM gregcnc_: or maybe even adding to http://wiki.linuxcnc.org/cgi-bin/wiki.pl
12:09 PM IchGucksLive: gregcnc_, they will only search YT
12:10 PM IchGucksLive: gregcnc_, every electronic mashine setup parts is different
12:10 PM gregcnc_: people have too much time. I'm tired of watching 30 minute video to get a paragraph of data
12:10 PM IchGucksLive: AS Always i will delete the YT as we hit 1mio clicks
12:10 PM gregcnc_: why?
12:11 PM IchGucksLive: as i do now 4 times
12:11 PM IchGucksLive: and resetup after a while with only new stuff
12:11 PM IchGucksLive: 5 maols within the last 15min
12:12 PM IchGucksLive: can a VFD do ETH
12:12 PM IchGucksLive: is there a color LASER engraver
12:12 PM gregcnc_: I hope YT is paying you well
12:12 PM IchGucksLive: how mutch are the cables and what size
12:13 PM IchGucksLive: i dont get anything
12:13 PM IchGucksLive: and will not do advertising
12:13 PM IchGucksLive: but i will delete
12:14 PM gregcnc_: i don't understand
12:14 PM IchGucksLive: can i install freewcad master on XP
12:15 PM IchGucksLive: only crazy people
12:18 PM IchGucksLive: i shoudt male a 4 Language video to get all this here that is a funny discussion
12:19 PM fragalot: still don't understand why you delete rather than just move on if you want to keep the channel size down
12:19 PM fragalot: at least leave the information up for those that haven't seen it yet
12:19 PM IchGucksLive: fragalot, you need to tear doen the mail
12:20 PM fragalot: Sure
12:20 PM fragalot: let the mailbox die out
12:20 PM IchGucksLive: no
12:20 PM fragalot: or set it to autoreply that it is no longer active
12:21 PM IchGucksLive: the new chennel is more informative as all versions change
12:21 PM IchGucksLive: thi is the best way to do it
12:21 PM fragalot: sure, btu the last few videos on the previous one could still apply
12:21 PM IchGucksLive: they will go up first
12:21 PM fragalot: Alright then. :)
12:22 PM IchGucksLive: if you do 3 Vidos a day you are in front row
12:22 PM IchGucksLive: and s i remap them all it is a new frech not refused
12:22 PM IchGucksLive: still 150k to go
12:29 PM fragalot: hey gloops
12:29 PM gloops: howdy
12:29 PM IchGucksLive: ;-)
12:29 PM fragalot: hi miss0r!
12:30 PM miss0r: hi fragalot!
12:30 PM IchGucksLive: miss0r, pig fence closed so boarder is up
12:30 PM gloops: ive gone from having frostbite to sunstroke in 3 weeks
12:30 PM miss0r: I suggested we added another two meters of height & barbed wire :D
12:30 PM IchGucksLive: gloops, in 10 days
12:31 PM gloops: yeah something like that, it snowed on april 1
12:32 PM IchGucksLive: we hit 28 today
12:32 PM IchGucksLive: and will get 29 tomorow
12:32 PM gloops: i think highest here was 29 today
12:33 PM gloops: almost 90f
12:33 PM IchGucksLive: a car is on the driveway whow 19:30 as they arive in the min new MTB guests
12:33 PM IchGucksLive: im off
12:35 PM gloops: well not much cnc making for me for a while really, next job is a bandsaw with 14inch + depth, cant decide whether to move the blade or the job
12:38 PM gloops: although now i have the cnc skills, i could cnc it haha, simple feed one axis
12:39 PM fragalot: gloops: my mill table is done :D https://i.imgur.com/tTP1oBS.jpg
12:39 PM gloops: now that does look nice fragalot
12:41 PM Rab: fragalot, nice ground finish. What governed the hole placement at the corners? They don't seem to line up with the rest of the pattern.
12:41 PM fragalot: Rab: linear carriages
12:41 PM gloops: you could have built the lot with iron
12:41 PM Rab: fragalot, bolted underneath?
12:42 PM fragalot: those are bolt holes, the others are precision alignment pin holes with M8 threads
12:42 PM fragalot: yes
12:42 PM Rab: ahh
12:42 PM Beachbumpete1: Looks good frag
12:43 PM fragalot: flat to within 2.4µ :-)
12:43 PM Beachbumpete1: size?
12:45 PM fragalot: 346x242 excluding coolant channel
12:46 PM fragalot: 376x272 including
12:47 PM gloops: so whats next?
12:47 PM fragalot: fixing the RF45 so I can machine the rest
12:48 PM gloops: still on with the scraping?
12:48 PM fragalot: then get more aggregates, and dump it all into the mold
12:48 PM fragalot: yeah I ordered a new surface plate as i've discovered the one I have now is less accurate than your average paver slab
12:48 PM fragalot: doesn't make sense to continue with it.
12:49 PM gloops: not really, if you take too much off
12:51 PM fragalot: also bought a decent scraper, my idea of using reground files is miserable
12:54 PM gloops: as they say here 'reyt tackles 'a'af the battle'
12:55 PM gloops: although typing a glottal stop doesnt work
12:58 PM CaptHindsight: fragalot: how would you go about scraping this bed flat? https://cdn.thingiverse.com/renders/f2/a2/d0/fd/1f/e1378d2258799495de87d94cba98108e_preview_featured.jpg
12:59 PM fragalot: CaptHindsight: I wouldn't?
12:59 PM fragalot: that alu is so thin that the instant you clamp something down on it it's going to warp
12:59 PM fragalot: the whole thing is an accordeon spring
01:01 PM CaptHindsight: is that why CNC machines are not made from accordion parts?
01:01 PM gloops: be ok for what its intended for
01:01 PM gloops: you dont clamp 4mm mdf with spanners
01:03 PM fragalot: gloops: even hand tight will warp that bed
01:03 PM fragalot: look at the cross section
01:03 PM fragalot: it's just a V V V V V V
01:03 PM Loetmichel: fragalot: its ok if it has only light loads
01:03 PM fragalot: Loetmichel: sure, but it's not worth scraping
01:03 PM Loetmichel: those "machines" are called "routers" rather than "mills" for a reason
01:03 PM Loetmichel: indeed
01:04 PM gloops: its got the flat opposing the V though
01:04 PM Loetmichel: i do use a sacrifical board an a 20mm router bit on mine occasionally...
01:04 PM fragalot: gloops: that flat offers no structural strength though
01:04 PM gloops: 3 angles there to bend
01:04 PM gloops: the strength is in the shape
01:05 PM fragalot: it would be very strong, if that flat was fully solid
01:05 PM CaptHindsight: fragalot: I apologize for bringing it up
01:05 PM fragalot: CaptHindsight: :D
01:05 PM fragalot: Apology accepted.
01:06 PM gloops: im not too keen on slots for woodwork, theyll soon fill up
01:06 PM fragalot: they can fill up all they want, easy enough to vacuum out
01:06 PM fragalot: or pushed clean with a Tslot scraper
01:07 PM Loetmichel: lucky you if its only the slots...
01:07 PM Loetmichel: i sometimes have the whole workshop with a golden (brass) or silver(alu) glitter cover
01:07 PM fragalot: xD
01:08 PM fragalot: beats what miss0r had a while ago
01:08 PM fragalot: machining big cast iron parts >.<
01:10 PM Rab: I was under the impression that aluminum router bed is generally decked by the machine using an end mill or fly cutter, rather than scraping. But there doesn't seem to be a hair's-breadth of extra material on that extrusion.
01:12 PM fragalot: normally what you'd do is put a sacrificial surface on first
01:12 PM fragalot: and likely unless you're engraving, not bother with flattening
01:13 PM gloops: skim the board underneath - add ally t slot
01:13 PM gloops: insane flatness
01:14 PM Rab: gloops, really? I thought Al extrusion had pretty poor dimensional tolerances.
01:14 PM fragalot: Rab: that's relative
01:14 PM Beachbumpete1: Miss my old RF45 CNC
01:14 PM gloops: adequate for most wood demands
01:14 PM fragalot: for woodworking, it's insanely accurate.
01:14 PM Loetmichel: Rab: usually you use a sacrificial board on those machines and DONT cut into the tslots ;)
01:15 PM Loetmichel: and face THAT off
01:15 PM fragalot: Beachbumpete1: I'll trade you my RF45 for a baby bridgeport?
01:15 PM fragalot: pick up only
01:15 PM gloops: i put spars on my frame, skimmed the spars off, added mdf top/s
01:15 PM Beachbumpete1: hehe
01:15 PM gloops: by the next day the pine spars will have swollen and the mdf
01:15 PM Beachbumpete1: I liked my RF45 better than the baby bridgie I had
01:17 PM fragalot: i've got some issues with mine where it /sometimes/ pops out of gear
01:17 PM fragalot: i've taken it apart completely, all of the gears look in perfect shape, replaced all the bearings even though the old ones felt fine
01:18 PM fragalot: so the only thing I can think of is that the spacing on them is off, which is non adjustable :/
01:19 PM Beachbumpete1: well I actually built a nice three phase VFD driven belt drive for mine so I had no such issues
01:20 PM fragalot: current issue with mine is that the X isn't square to Y
01:20 PM fragalot: which is an issue that is in progress to be fixed, but will take at least a week or so to complete
01:20 PM Beachbumpete1: you in UK?
01:20 PM fragalot: no
01:25 PM Beachbumpete1: https://www.cnczone.com/forums/benchtop-machines/80008-cnc-tormach.html
01:25 PM Beachbumpete1: that is my old RF45 belt drive conversion thread over on the zone
01:27 PM fragalot: neat job :)
01:27 PM fragalot: i've not needed a VFD on mine yet; but I think i'm the first person to have run the machine on it's nominal voltage since it was built
01:27 PM fragalot: previous owner ran it on 3x220V when it's a 3x380V machine
01:28 PM fragalot: hearing it attempt to spin up to 3000rpm was painful when I first viewed it
01:28 PM fragalot: upside, I figured, ws that it couldn't have had a hard life :P
01:30 PM Beachbumpete1: https://www.cnczone.com/forums/benchtop-machines/67417-cnc.html this is the CNC buildup
01:31 PM Beachbumpete1: believe it or not mine was wired 110v when I bought it originally
01:31 PM Beachbumpete1: I kept it that way manually for over a decade before I tore it down and converted to CNC/ballscrews/Servos etc...
01:32 PM fragalot: I thinkt he most i'm going to do to mine apart from the DRO I fitted is going to be a power feed on all axis
01:32 PM fragalot: Maybe.
01:34 PM Beachbumpete1: they really make a great little CNC tho
01:34 PM Beachbumpete1: mine was quite fun and cut pretty damn good despite mach3 LOL
01:34 PM fragalot: yeah but the EG build will cover the cnc needs :)
01:34 PM fragalot: for the rf45 to make sense as a cnc mill i'd have to do too much to it
01:34 PM fragalot: replace the whole spindle assembly, for one
01:35 PM fragalot: it's too sloppy to keep a tolerance
01:41 PM jwhite: naive newb question: I'm mentoring an FRC robotics team with an old probotix fireball cnc, currently driven by a senior with an Inventor -> estlcam -> thumb drive -> LinuxCNC work flow.
01:42 PM jwhite: The senior is graduating, the rest of the team uses OnShape, and the students coming up are not as sophisticated as the senior. I'm hoping to make use of kiri:moto (cam plugin) and this interface specifically: https://github.com/GridSpace/grid-apps/wiki/GCode-Sender-in-CAM-Mode
01:43 PM jwhite: I'm wondering how feasible it would be for me to try to rig a serial/json interface to drive a linuxcnc rig, or if I'm just on crack.
01:45 PM CaptHindsight: by drive do you mean actually act as the user interface?
01:45 PM jwhite: Yeah, kiri:moto appears to be able to provide a simple user interface; feeds simple commands and then the gcode.
01:45 PM CaptHindsight: or do you just want to send g-code files to LCNC? or?
01:46 PM jwhite: I guess a first step would be to understand if there are standard ways to feed g-code files into LCNC, or even a cli I can use
01:48 PM CaptHindsight: do you have Inventor on Winders PC's?
01:48 PM jwhite: yeah
01:48 PM * hazzy-dev just found this router in a dumpster: https://i.imgur.com/VxzUIkX.jpg
01:48 PM jwhite: hoping to replace that, though.
01:49 PM pink_vampire: hazzy-dev: where??????
01:49 PM CaptHindsight: and you'd like to use that or those PC's for CAM and to be the UI for the LCNC machine?
01:49 PM hazzy-dev: I was thinking I would salvage the thomson rails, but it seems decent, might put motors on at and use it
01:49 PM fragalot: neat find, lol
01:49 PM hazzy-dev: pink: At my brothers shop, guess he is cleaning up :)
01:49 PM pink_vampire: deep the rails in evapo rust
01:50 PM hazzy-dev: Pink: Doing that now, go the evapo rust 5gal pail out already
01:50 PM pink_vampire: cool!
01:51 PM jwhite: CaptHindsight, I'd like to be able to use OnShape on a PC to drive the LCNC machine, yes. (could be a linux box; onshape is nicely cloud based).
01:51 PM CaptHindsight: jwhite: what do you want to replace the .... ah ok
01:51 PM XXCoder: hazzy-dev: dang! thats easy enough to clean and fix
01:51 PM XXCoder: wonder why it was dumped
01:52 PM fragalot: looks like it just wasn't used enough anymore?
01:52 PM XXCoder: probably
01:52 PM jwhite: seems like my alternate would be to replace the computer currently running LCNC altogether with something like a Pi/parallel driver. But I'm a software guy, so I'm more willing to screw around in software, rather than screw up the wiring.
01:52 PM XXCoder: rails do have issues
01:52 PM XXCoder: bearings need replacement probably
01:54 PM CaptHindsight: jwhite: then you are getting rid of the CNC controller
01:54 PM fragalot: jwhite: in the end all lcnc needs is a gcode file, and be told to run it
01:54 PM gloops: i never find stuff like that hazzy! i must start digging deeper
01:55 PM jwhite: right, so the question is if there is a command line way to say to lcnc 'please run this gcode'
01:55 PM miss0r: gloops: don't waste your time on that. Just get'yer own one working ;)
01:55 PM gloops: miss0r if i found that id have a week off
01:55 PM * jwhite read the wiki and doco and did not find it in a first pass. apologies if it was there and I missed it.
01:55 PM CaptHindsight: jwhite: you can run LCNC from the winders desktop using VNC
01:56 PM miss0r: gloops: I thought your router was; quote: "in perfect mechanical condition"
01:56 PM miss0r: ?
01:56 PM gloops: mine is working anyway, replace drivers at weekend, ive rewired a seperate feed for router to garage on its own circuit breaker
01:56 PM gloops: miss0r it is
01:57 PM miss0r: Great:D Can I have some pictures of your control box now, then? :D
01:57 PM gloops: not got any
01:57 PM jwhite: CaptHindsight, sure. And that, or something like it, is my default plan. But that requires a workflow of OnShape -> Kiri:Moto -> Export -> thumb drive/scp -> lcnc. The workflow I imagine is Onshape -> Kiri:Moto -> Part. The key being that LCNC seems to be quite good at driving oddball hardware combos like the parallel port driven control we've got.
01:57 PM miss0r: you could easily make one?
01:58 PM gloops: not at this moment, its all closed up
01:58 PM CaptHindsight: jwhite: I'm not familiar with OnShape, does it run in only on Windows?
01:58 PM miss0r: Alright, but when you go about changint to the new drives, snap me one. I'm realy curious
01:58 PM CaptHindsight: -in
01:58 PM gloops: right, i will
01:58 PM jwhite: CaptHindsight, it's cloud based, so it runs in modern browsers. It's pretty slick, actually.
01:59 PM fragalot: jwhite: halcmd could be something to look into ?
01:59 PM gloops: thing is, theres so many wires in the box i doubt anyone else could make sense of it
01:59 PM fragalot: I've never used it myself though, but it is a way to interface with lcnc via a CLI
01:59 PM CaptHindsight: jwhite: your parallel port "controller" is probably just drivers for the motors
02:00 PM CaptHindsight: jwhite: the controller is actually LCNC
02:00 PM miss0r: gloops: you'd be surprised
02:00 PM CaptHindsight: jwhite: so if you take away the LCNC PC you are left without a controller
02:01 PM fragalot: gloops: you're forgetting that making sense of boxes crammed with wires is part of our day job :P
02:01 PM gloops: it doesnt look any different to the telecom box at the end of the road, when theyve got it open
02:01 PM CaptHindsight: jwhite: is this https://www.thingiverse.com/apps/kirimoto it?
02:01 PM Loetmichel: fragalot: you neatly described an electronican ;)
02:02 PM fragalot: Loetmichel: :-)
02:02 PM miss0r: :]
02:02 PM jwhite: CaptHindsight, yeah, that's it. (the link I posted above has more detail on the specific feature I was hoping to use).
02:02 PM Loetmichel: fragalot: my uncle was a "below ground" telecom worker
02:02 PM jwhite: fragalot, yeah, I read the halcmd man page; that seems lower level than I crave.
02:02 PM miss0r: gloops: You seriously should let us be the judges. Don'e be ashamed if it is a mess. We can most likely pinpoint anything from such a picture
02:03 PM miss0r: It wouldn't hurt to try
02:03 PM fragalot: jwhite: i'm not entirely sure if there is a higher level :/
02:03 PM CaptHindsight: jwhite: if the CAD and CAM/Slicer run on the cloud and use a browser for UI then you could used a Linux PC and run the LCNC GUI over the network using X
02:03 PM Loetmichel: i once visited him on job... in a 3m deep hole in the tarmac, in -5°C winter, snowing and patching a 2000DA cable that the excavator damaged.
02:03 PM CaptHindsight: used/use
02:03 PM jwhite: fragalot, ah, rats :-/.
02:03 PM Loetmichel: i REALLY pitied that man
02:03 PM fragalot: Loetmichel: yeah.... :/
02:04 PM gloops: well ive described what i did, metal box, 3 compartments a) vfd b) drivers/bob c) psus
02:04 PM gloops: everything is shielded, twisted, grounded
02:04 PM miss0r: Loetmichel: i've done that... only I think it was only a 500 pair cable. But the 'hole' was covered with one of those steel plates, and I was underneath it with cars driving over it - in the rain :/
02:04 PM Loetmichel: nice
02:04 PM Loetmichel: sounds comfy
02:04 PM Loetmichel: :-)
02:05 PM fragalot: cosy.
02:05 PM jwhite: CaptHindsight, yeah, that's an option, although we may also just set lcnc up with a dedicated monitor / keyboard / mouse and use it as a controller station.
02:05 PM jwhite: Does lead to my next question: do people have a favorite / common way to dump gcode files to their lcnc box? ftp? scp?
02:05 PM cradek: scp
02:05 PM gloops: usb
02:06 PM fragalot: usb or scp, depending on..
02:06 PM cradek: scp or sshfs
02:06 PM fragalot: for the 3D printer I just dump the file onto an SD card and ram it into the RAMPS controller
02:06 PM miss0r: it was hell. The worst part, probally, what that the plates covering the trench in the road, was sorta 'off balance' so it made a huge boom every time a car drove over it in a specific place...
02:06 PM fragalot: then fiddle with the encoder wheel desperately trying to select the file
02:06 PM cradek: I don't like fiddling with floppies or their modern substitutes
02:07 PM cradek: the only good substitute is a cat5 cable
02:08 PM jwhite: cool. my instinct is to put a dhcp server on and then set up an sshfs or ftp server to let students up/download files. leads to next question:
02:08 PM miss0r: gloops: I understand what your setup is: but how you have done it in practice is what I would like to look at. Wouldn't it be foolish of you to deny me that, if it turns out I can pinpoint it from looking at a single picture? and save you alot of trouble
02:08 PM jwhite: wiki seems to suggest that debian with an rt kernel on relatively decent hardware should be good enough. Is that true, or is rtai really the way, the truth, and the light?
02:09 PM CaptHindsight: depends on hardware
02:10 PM Loetmichel: jwhite: sneaker net with thumbdrives here
02:10 PM Loetmichel: the CNC HAS network connect
02:10 PM CaptHindsight: the FPGA's over Ethernet only have drivers for preempt_rt
02:10 PM Loetmichel: but its a bit picky to reach
02:10 PM Loetmichel: so i usually use my feet.
02:11 PM Loetmichel: have to get to the machine anyways to get material on and a mill bit in ;)
02:12 PM Loetmichel: i do ocaasionally use it as a server for the endoscopic webcam thats mounted on the spindle
02:12 PM Loetmichel: and for VNC
02:12 PM Loetmichel: works great, even if it only has a core2duo 3ghz
02:13 PM gloops: miss0r ill get a pic at the weekend
02:13 PM jwhite: Loetmichel, sweet; I have a 3ghz core2duo gathering dust... :-)
02:13 PM cradek: jwhite: rtai is better for software step generation. otherwise the rt kernel is fine.
02:13 PM gloops: if anything i needed a far bigger box
02:13 PM miss0r: gloops: I will hold you to your word ;)
02:14 PM Loetmichel: https://youtu.be/9u_ChO1AKYY
02:14 PM Loetmichel: (caution, second part loud)
02:16 PM fragalot: sweet, my new function gen shipped
02:16 PM CaptHindsight: jwhite: I don't see any reason to pull LCNC from your setup
02:16 PM CaptHindsight: unless you just want to....
02:16 PM CaptHindsight: but then you'll need some other controller
02:18 PM XXCoder: hopefully not one of those shitfirmware like marlin, etc
02:19 PM XXCoder: I may like 3d printing but their firmwares suck
02:19 PM jwhite: CaptHindsight, well, I don't see any way to accomplish what I was imagining, so, sure.
02:19 PM fragalot: XXCoder: my ramps board running marlin does just fine
02:19 PM fragalot: i hit start, part comes out
02:19 PM CaptHindsight: jwhite: UI over X or VNC
02:19 PM fragalot: could it be better? maybe. I don't have the hardware rigidity for that to matter though.
02:20 PM CaptHindsight: jwhite: you just have to choose what PC's the cloud stuff will run on
02:20 PM XXCoder: yeah though one of bigger issues is that it converts g2 g3 to linear segements
02:20 PM XXCoder: it doesnt do true arcs like linuxcnc does
02:21 PM fragalot: that may be partly due to the hardware it typically runs on
02:22 PM XXCoder: funny thing someone is working on it and its "revolory"
02:22 PM XXCoder: dammit cant spell that word
02:22 PM CaptHindsight: marlin seems to work for a few people that have the time to tweak it for applications that it was written for (machines from hell)
02:22 PM fragalot: :D
02:24 PM XXCoder: lol
02:24 PM hazzy-dev: XXCoder: My brother dumps all kinds of "trash", that I think is "gold" that is why I keep a good eye on his junk pile :)
02:24 PM hazzy-dev: If he gets something newer/better he trashes the old, exactly the opposite of me, who saves EVRYTHING!
02:24 PM hazzy-dev: I hit the jack pot once and got all this tooling: https://i.imgur.com/YI56JYD.jpg
02:24 PM hazzy-dev: I cleaned it up and sent him a pic and he said, "where did you get all that tooling?" And I said "from YOU!!"
02:24 PM fragalot: lol
02:24 PM hazzy-dev: He always wants the stuff back, but I don't let him take it :D
02:25 PM fragalot: i'm more jealous of the open floor space back there than I am of the tooling
02:25 PM XXCoder: hazzy-dev: awesome!
02:26 PM XXCoder: including kurt eh?
02:26 PM hazzy-dev: Haha, the Kurt is a funny story!
02:27 PM hazzy-dev: All the ME students at Ga Tech make KURT plaques for CAM project, when they turn them in they go to me!
02:28 PM hazzy-dev: They think it is KURT for the workholding co, but it is actually Kurt for my name, lol
02:28 PM gregcnc_: so you put them on everything?
02:28 PM XXCoder: lol well you wont be out of nameplates anytime soon then
02:29 PM hazzy-dev: gregcnc_: yes! I have buckets of them
02:29 PM gregcnc_: lol
02:29 PM fragalot: KURT monitor
02:29 PM fragalot: KURT ballpoint pen
02:29 PM fragalot: KURT toilet roll holder
02:30 PM XXCoder: KURT Kurt logo
02:30 PM XXCoder: okay the joke kurts
02:31 PM hazzy-dev: LOL
02:35 PM Rab: jwhite, maybe you're looking for something like this? http://linuxcnc.org/docs/html/man/man1/linuxcncrsh.1.html
02:36 PM Deejay: namd
02:36 PM Deejay: evening ;)
02:36 PM Rab: There's also this, but given the reference to EMC1 it might not be currently maintained: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Keystick
02:37 PM jwhite: Rab, aha, yes, that was exactly what I was looking for, thanks!
02:44 PM Beachbumpete1: hehe
02:45 PM CaptHindsight: jwhite: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Running_Multiple_User_Interfaces
02:45 PM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Emcrsh
02:46 PM Rab: jwhite, I think the emphasis on GUI is because for most machine tool setups, some level of interactive control is needed. If e.g. a tool breaks during the job, the operator wants to halt the machine and perform manual steps to recover and finish. With big machines it's a serious safety, money, and time issue. Fire and forget straight from your CAM program is common for 3D printing, but
02:46 PM Rab: inconvenient or dangerous for machining.
02:46 PM Rab: Of course you know how your machine is used, and whether any interactivity is needed.
02:46 PM CaptHindsight: no machining from your smartphone while at the beach
02:47 PM jwhite: heh. tbh, I'm a complete newb, and am basically trying to learn / set up the infrastructure to be as simple and robust as possible. It's a small cnc, and our 'e-stop' procedure is to kill power to the whole rig.
02:48 PM adamj12b: Does anyone know how to change the type of message displayed with the (MSG) command? I would like to display the red X instead of the while !
02:48 PM fragalot: jwhite: do the power supplies shut down fast enough?
02:49 PM XXCoder: Rab: one of things I hate about 3d print hosts is that theres no e-stop. or basically any way to stop
02:49 PM CaptHindsight: jwhite: no big e-stop button right out in front?
02:49 PM XXCoder: (between commands that is)
02:50 PM jwhite: CaptHindsight, big red power button in front, not really an e-stop.
02:50 PM hazzy-dev: adamj12b: Are you using axis?
02:50 PM XXCoder: Rab: ie if I start home and it screws up, only way to stop is unplug
02:50 PM CaptHindsight: XXCoder: bloat and sounds like somthin those PC controller people would do :)
02:51 PM XXCoder: its what happens when computer scientist (not cnc engineer) develops first reprap
02:54 PM hazzy-dev: adamj12b: I don't think you can configure the messages much in axis. Gmoccapy has some setting for changing the style of the message popups, but you still can't specify which icon is used for OPERATOR_DISPLAY messages etc.
02:57 PM hazzy-dev: adamj12b: You might be able to find the red icon axis uses and replace the white one with it, I don't think axis uses system icons, so that should work without messing any other apps up
03:02 PM adamj12b: hazzy-dev: Yea, pretty much what I thought.
03:11 PM Tom_L: adamj12b, i think it has to do with the severity of the message
03:12 PM Tom_L: you can suppress them
03:12 PM Tom_L: http://linuxcnc.org/docs/2.7/html/gui/axis.html#_axisui_pins
03:12 PM Tom_L: see 11.9
03:23 PM * jwhite off to go fiddle with the cnc box; thanks for all the help. It's nice as a newb to find such a remarkably friendly crew.
03:28 PM CaptHindsight: what was all the hullabaloo over wanting to replace NML with something else for network based control and UI?
03:29 PM CaptHindsight: guess I'll look over some old mail list threads
03:32 PM CaptHindsight: wow, summed up here https://github.com/machinekit/machinekit/issues/1348
03:36 PM DocHopper_: Hey linuxcnc, I've got a very low level design question. I've got mosfets powering motors on an arduino, where in this circuit would YOU choose to put leds to monitor when the mosfet is active or not? https://imgur.com/a/hI0J9sI
03:41 PM gloops: Robots assemble an IKEA chair frame https://reut.tv/2J7DHU0
03:45 PM Deejay: gn8
03:46 PM pcw_mesa: in the gate circuit
03:50 PM XXCoder: gloops: bah hate when this happens. I see that it has captioning icon and think "yay!" and click it. first and only sentance is "captioning on prgress..."
03:51 PM gloops: hmm, not good XXCoder
03:55 PM DocHopper_: pcw_mesa: I'm sorry, where?
03:55 PM pcw_mesa: from gate to source (with a series resistor)
03:57 PM pcw_mesa: high efficiency LEDs if the gate drive source is weak
03:58 PM pcw_mesa: or across the load with standard LEDs (since its only 12V)
03:58 PM DocHopper_: pcw_mesa: Ah, since the mosfet is driven high, just take it from there.
03:59 PM pcw_mesa: yeah as long as you dont lose to much gate drive voltage from the LED load on the gate drive signal
03:59 PM pcw_mesa: otherwiise across the load with a resistor appropriate for 12V
03:59 PM DocHopper_: pcw_mesa: That's a good point, the arduino is kinda wimpy.
04:00 PM DocHopper_: pcw_mesa: I was afraid the 12v source would be too much for a 1/4w resistor, but that's because I don't know the electronics formulas yet.
04:01 PM pcw_mesa: 10V@10 ma is only 100 mw
04:01 PM pcw_mesa: (12V - LEDV ~=10V)
04:02 PM DocHopper_: pcw_mesa: And it's better to have it after the mosfet so I can monitor the whole circuit, not just the arduinos output state.
04:03 PM pcw_mesa: Yeah since only 12V and you have wimpy gate drive probably better there
04:04 PM DocHopper_: pcw_mesa: I drew it like this from the 5v https://imgur.com/a/hI0J9sI
04:04 PM DocHopper_: But I'll swap it back to the 12v to simplify the circuitry.
04:06 PM pcw_mesa: That will reverse bias the LEDs (but only to 7V)
04:07 PM DocHopper_: pcw_mesa: I'm sorry, I don't understand.
04:07 PM DocHopper_: pcw_mesa: Does a 5.6k ohm resistor sound right for an LED over the 12v?
04:08 PM Rab: DocHopper_, connect the LED/resistor between the anode of D1 and GND.
04:08 PM pcw_mesa: when off, the LED will be reverse biased (cathode at 12V, anode at 5V)
04:09 PM Rab: Wait, never mind, disregard.
04:09 PM DocHopper_: pcw_mesa: Isn't a diode made to be okay with that?
04:09 PM pcw_mesa: this exceeds the specs of many LEDs (though probably fine)
04:10 PM pcw_mesa: no thats for inductive loads the LED will still be reverse biased when the MOSFET is off
04:10 PM Rab: Sorry, put the LED/resistor in parallel with D1.
04:11 PM Rab: But forward-biased to the FET drain, while D1 is reverse-biased.
04:11 PM pcw_mesa: yes 5.6k would be a bit less than 2 mA, fine for high efficiency LED maybe a bit dim for normal
04:11 PM DocHopper_: pcw_mesa: Okay, well luckily we've already decided to move the LED to the 12v line. But if I were to use the 5v rail, how would I resolve that issue.
04:13 PM pcw_mesa: either dont worry about it or put a different color LED across the original one and get a on/off LED :-)
04:13 PM Rab: DocHopper_, you wouldn't, that would complicate the circuit for no purpose.
04:14 PM DocHopper_: Rab: I understand I wouldn't. But as an exercise in teaching me how to resolve the issue, what would we do?
04:14 PM Rab: DocHopper_, there would be no issue because you would not choose to do that. ;)
04:15 PM DocHopper_: Rab: You really don't get what I'm asking?
04:15 PM Rab: DocHopper_, it's like asking how you could run the circuit from reverse power. Why would you do that? Is it a realistic scenario?
04:16 PM Rab: Are you asking how you would handle a situation where an LED might be reverse-biased?
04:16 PM DocHopper_: Rab: Okay, how does one prevent an LED from being reversed biased?
04:16 PM DocHopper_: Rab: Yes.
04:18 PM pcw_mesa: if you really wanted to do this you could put a reverse diode across the LED (but I like the 2 color LED idea better)
04:18 PM pcw_mesa: red for off green for on
04:18 PM Rab: DocHopper_, I see applications reverse-bias LEDs all the time, although it's generally not advised. E.g. indicator LED powered from AC. If you really need protection, you can put a conventional diode in series with the LED.
04:21 PM DocHopper_: Rab: So you double diode, since the LED has weak reverse bias resistance?
04:22 PM DocHopper_: pcw_mesa: that sounds neat!
04:22 PM Rab: DocHopper_, generally, you would not make design choices which might apply reverse voltage to the LED. But you could do that, if it's unavoidable.
04:22 PM DocHopper_: Rab: I understand.
04:23 PM DocHopper_: pcw_mesa: Would the dual color LED be easy to implement here?
04:25 PM Rab: pcw_mesa's idea is very clever. But I think it overcomplicates the circuit. And if +12V is turned off while +5V is still applied, I think it will leak a few volts onto the +12V rail--with whatever consequences might accompany that condition.
04:26 PM DocHopper_: Rab: Well maybe it'll get implemented in V2!
04:26 PM pcw_mesa: yeah just use your 5V led driver circuit and replace the single LED with a back-back LED pair
04:27 PM pcw_mesa: (there are back-back LEDs in a single package)
04:29 PM DocHopper_: pcw_mesa: But isn't the reverse voltage 7v?
04:34 PM Rab: If you use a red/blue LED, the blue LED will have (very approximately) 2V more forward voltage drop than the red. So if red is forward-biased (indicates on) and blue is reverse (indicating off), either LED will draw approximately the same current through the resistor.
04:34 PM Rab: But I still claim it's a bad idea, because of the voltage leakage issue.
04:36 PM Rab: Also, it assumes your loads REAR_AIR/REAR_VAC/etc are happy with a small current at reverse polarity. Maybe that's not the case.
04:36 PM DocHopper_: Rab: I'm not going to do it, because I don't have a good understanding of it, therefor, I can't troubleshoot it effectively.
04:37 PM Rab: DocHopper_, an admirable calculus.
04:57 PM asdfasd1: any clue where I can buy such handle?
04:57 PM asdfasd1: https://ibin.co/3yxuqZkp1rk4.jpg
05:02 PM Rab: asdfasd1, where are you located?
05:04 PM asdfasd1: I mean online
05:05 PM Rab: https://www.mcmaster.com/#crank-handles/=1chhlr5
05:06 PM Rab: That's USA, with industrial pricing (although I see a few economical options).
05:06 PM DocHopper_: Rab: Thanks for the help, it seems to be working! https://imgur.com/a/8eBQ45x
05:07 PM Rab: DocHopper_, great!
05:07 PM DocHopper_: Rab, I didn't really doubt it, but it's always a good idea to take a swing at it anyways.
05:08 PM asdfasd1: Rab: that seems similiar but prices are way too much
05:08 PM Rab: asdfasd1, I also see a bunch of options on eBay. "Crank handle" seems to be the magic search term.
05:09 PM asdfasd1: I did try on ebay but only found car spares, for windows
05:10 PM Rab: I see a lot of non-automotive options, maybe eBay is trained to think I'm searching for machinist stuff.
05:11 PM asdfasd1: I will try again then
05:11 PM asdfasd1: thanks
05:12 PM DocHopper_: asdfasd1: Is there a reason you don't want to fabricate one?
05:12 PM Rab: Sure. If you want to match the one you have, you might want to remove it and check how it's fixed to the shaft. Square drive seems to be common, but it's not obvious from the pic.
05:14 PM asdfasd1: dont want to waste time making if I can find a supplier with reasonable price
05:14 PM Rab: Lots of options here, some more expensive than others: http://stores.ebay.com/Supra-Machine-Tool/Handwheels-Handles-/_i.html?_nkw=crank+handle&submit=Search&_fsub=5509840015&_sid=1014199095
05:15 PM DocHopper_: asdfasd1: Approximate dimensions?
05:15 PM DocHopper_: Location?
05:16 PM Rab: This one's pretty cheap. But again, the match will depend on the shaft drive style (and measurements): https://www.ebay.com/itm/171026252257
05:16 PM asdfasd1: Rab: wow thanks for the link, look just what I wanted
05:16 PM asdfasd1: yep, that one should do the job
05:16 PM asdfasd1: thanks a lot
05:17 PM DocHopper_: Rab: Is that your store? You little sneak!
05:18 PM Rab: DocHopper_, it is not I.
05:30 PM CaptHindsight: Rab: " how you could run the circuit from reverse power", from high power resistors of course :)
06:00 PM Tecan: http://netpipe.ca/?p=956 rss news... took long time today
06:20 PM TurBoss: hello
06:20 PM TurBoss: I just installed stretch image
06:21 PM TurBoss: but it doesn't have a calc :D
06:33 PM CaptHindsight: TurBoss: can't you install a calculator package?
06:41 PM TurBoss: what one?
06:41 PM TurBoss: xfce one
06:51 PM Rab: TurBoss, I like Qalculate!: https://qalculate.github.io/
06:51 PM Rab: It's already in Debian, sudo apt install qalculate
06:51 PM TurBoss: ty
06:51 PM TurBoss: oh amazing
06:52 PM hazzy-dev: TurBoss: The LCNC Stretch image?
06:52 PM TurBoss: yes
06:53 PM TurBoss: sadly I depend on stepgen
06:53 PM TurBoss: :D
06:53 PM hazzy-dev: It should come with a galculator
06:53 PM hazzy-dev: Look in accessories menu
06:53 PM TurBoss: lol
06:54 PM CaptHindsight: the XFCE install doesn't come with much installed, that is the whole point
06:54 PM TurBoss: I meas
06:54 PM TurBoss: I mean
07:02 PM TurBoss: oh it galculator is installed
07:02 PM TurBoss: butnot in the accesories menu
07:06 PM Rab: Sorry mang. Surely XFCE has a way to create menu shortcuts?
07:07 PM hazzy-dev: TurBoss: That is very odd, and it is in the menu here: http://i.imgur.com/qZrr8bD.png
07:08 PM hazzy-dev: bbl
07:08 PM Rab: hazzy-dev, that's galculator, not to be confused with qalculate.

07:11 PM enleth: does anyone here have experience with fixing/adjusting horizontal bandsaw vise nuts?
07:12 PM enleth: http://www.kenosha-reuse.com/RACINE,-WI/Commercial/Mechanical/Refurbished/No-Warranty/New-acme-nut-assembly-for-vise-on-7-x-12-metal-band-saw-picture-1.jpg a funny nut just like this
07:12 PM enleth: threaded on one side only and shaped so that it's supposed to rotate/rock left and right in the movable bracket
07:13 PM enleth: in order to lock when the screw is rotated in one direction and disengage when it's rotated in the other
07:13 PM enleth: problem is, mine pretty much doesn't hold at all
07:13 PM enleth: slips every time I try to tighten the vise
07:13 PM enleth: the saw is used, I got it very cheap, previous owner warned me about this issue
07:14 PM Rab: weird
07:15 PM Rab: Is the screw in good shape?
07:16 PM Rab: Maybe there's a missing spring.
07:17 PM enleth: yeah, one thread on hobby-machinish.com suggests there should be a spring of some kind
07:17 PM enleth: the screw looks as good as it gets - it's shitty, but its shittiness factor is more or less constant along the whole thing
07:19 PM Rab: If you jam something under the nut so it can't move to disengaged position, can you then tighten it?
07:20 PM Rab: Maybe the nut threads are damaged, and it wants to cam off the screw under pressure.
07:24 PM enleth: they look, uh... ACME-ish, no obvious signs of any horrible wear
07:24 PM enleth: I guess trying to jam something in there could work
07:25 PM enleth: I have to assemble this vise upside-down on a bench to see what it does when rotated
07:26 PM enleth: worst case, I do have one left-handed ACME screw around that I don't need, there's a nut on it, but I'd have to turn an extension with all the shoulders and whatnot and weld it
07:39 PM enleth: okaaaay, it's possible that the previous owner disassembled that vise for cleaning or whatever and failed to reassemble it properly
07:39 PM enleth: there are four possible ways to install this nut
07:39 PM enleth: only one is correct
07:40 PM enleth: let's see what happens when I put it together correctly
07:42 PM hazzy-dev: enleth: If I understand what kinda vise that is they do NOT have a spring, but rely in the friction between the screw and nut to rotate it into pos
07:42 PM hazzy-dev: I would make sure that the nut is able to rotate freely in its housing and is not getting hung up by old grease/chips etc.
07:52 PM enleth: yep, it works exactly like that
07:52 PM enleth: and it was just misassembled
08:16 PM enleth: slipped once or twice when tightening, but otherwise it works fine
08:17 PM enleth: held a 60mm OD/52mm ID/80cm long steel pipe, most of it hanging off to the side
08:17 PM enleth: that's reasonable
08:18 PM enleth: I wouldn't expect a vise like this to hold anything longer/heavier anyway
08:18 PM enleth: not unsupported, that is
09:46 PM Isleape1 is now known as Isleape
10:49 PM hazzy-dev: enleth: Glad to hear you got it working properly
10:49 PM hazzy-dev: gn8 gang
11:08 PM CaptHindsight: ER16 collet nuts come with two different internal threads
11:08 PM CaptHindsight: is the M19-1 a Chinese oddball version?
11:09 PM enleth: let me guess - the varieties are cantonese and guangonese?
11:09 PM enleth: *guangdonese
11:09 PM CaptHindsight: Maritool only carries the ER16 with the M22-1.5
11:10 PM enleth: I'll check all of mine tomorrow out of curiosity
11:10 PM CaptHindsight: schezwan mini nut?
11:10 PM enleth: M19 seems a bit small, though
11:10 PM CaptHindsight: yeah but that is the size of the spindle
11:11 PM CaptHindsight: http://www.shars.com/er-16-mini-collet-nut
11:11 PM enleth: that's barely 2mm wider than the collet
11:11 PM enleth: the collet taper must extend right up to the edge of the thread with a pretty sharp edge
11:12 PM CaptHindsight: Shars carries both a m19-1 and the m22-1.5 ER16 nuts

11:15 PM CaptHindsight: you have to watch the version Chinese spindle that you order
11:15 PM enleth: luckily this is just a nut, only need one for a spindle
11:15 PM enleth: so not a huge deal
