01:42 AM IchGucksLive: morning from Germany
01:44 AM IchGucksLive: hazzy why is the programm that long
01:49 AM IchGucksLive: hazzy1: ?
02:22 AM Deejay: moin
02:41 AM IchGucksLive: till later its Friday 13 in germany noot a good sign
03:21 AM Valen: hey archivist got a question you might be able to answer, I was thinking about doing some brass with a black inlay like a chapter ring on a clock but I was wondering about gold plating the brass
03:22 AM Valen: Do you know a decent way to get the black inlay into it after doing that? I was thinking the black shellac/wax type stuff for the inlay but I can't think of a way to do it without sanding it and sanding it would rip the gold off
03:22 AM archivist: just polish and varnish, gold does not look much different
03:23 AM archivist: the plating usually silver is after the levelling
03:24 AM Valen: That was my plan B
03:25 AM archivist: silver being an easy process that only needs the powder rubbing on with a damp cloth
03:25 AM Valen: Just thaught there might be some special way of doing it I don't know of ;->
03:25 AM Valen: nah needs the gold colour for contrast for this one, the rest is stainless
03:25 AM archivist: bare brass
03:26 AM Valen: eh it'll do I guess
03:26 AM Valen: just wanted to be special is all ;->
04:55 AM RyanS: what material for the black inlay?
05:18 AM jthornton: morning
05:27 AM RyanS: o/
05:30 AM XXCoder: hey
05:36 AM archivist: RyanS, the proper stuff for clock dials is sealing wax, a hard wax
05:42 AM RyanS: ah, yeah i saw that done on the clickspring youtube channel
05:47 AM RyanS: jthornton- does the 7I76 bob have the same pinouts as the 7I76e ?
05:51 AM IchGucksLive: hi from germany
05:52 AM IchGucksLive: RyanS: yes
05:52 AM RyanS: thanks
05:53 AM IchGucksLive: RyanS: did you got the message yesterday on plasma thc
05:55 AM RyanS: i think i saw message
05:55 AM IchGucksLive: RyanS: we got 4 plasmas running
05:57 AM IchGucksLive: RyanS: scroll down here to see thep roducts we make http://www.schweden-feuer.de/feuersauelen.htm
06:02 AM RyanS: does the thcad output get treated as an encoder input and arc ok, start arc as digital outputs on the bob (via relays)?
06:02 AM jthornton: yea
06:04 AM IchGucksLive: RyanS: this is my plasma cabinett http://heimwerkermarkt-tretter.de/schrank.jpg
06:04 AM RyanS: IchGucksLive nice. i want to make lampshades, vases, boxes etc
06:06 AM archivist: tin snips
06:07 AM RyanS: no, cnc plasma and tig welder :-)
06:07 AM archivist: soldering iron ball bearing!
06:08 AM archivist: http://www.collection.archivist.info/searchv13.php?searchstr=tinware+PD
06:10 AM RyanS: IchGucksLive tidy cabinet. i like din terminals . where is the THC?
06:11 AM IchGucksLive: RyanS: THC is on the lpasma itself shortest HIGpower cables as posible
06:11 AM IchGucksLive: mine are 25cm
06:12 AM IchGucksLive: RyanS: i do not wire up the ARC_ok
06:12 AM IchGucksLive: as i use UserMcodes to start plasma
06:13 AM RyanS: because of voltage drop? short cables
06:13 AM IchGucksLive: i start ARC_ok signal to thcud with Mxxx after penetration
06:13 AM IchGucksLive: RyanS: EMI
06:14 AM IchGucksLive: the cables between THC and Cabinett are double shieldes
06:14 AM IchGucksLive: 12V and 24V
06:14 AM IchGucksLive: as THC up /Down
06:15 AM IchGucksLive: 4wire 24V line and 2 Wire 12V line
06:16 AM RyanS: but you cant just use shielder wire from voltage divider?
06:22 AM RyanS: my plasma came with this https://www.weldingsuppliesfromioc.com/hypertherm-25ft-cnc-machine-interface-cable-w-voltage-divider-228350
06:23 AM RyanS: i don't know if its shielded
06:23 AM IchGucksLive: the hypertherm has a internel voltrige devider
06:24 AM IchGucksLive: WHAT thc are you using
06:24 AM IchGucksLive: 94Dollares for a plug and some cable whow
06:26 AM IchGucksLive: RyanS: its 4Dollar plug i connect https://www.reichelt.de/bilder/blaetterkatalog/B2C/DE-DE/hkaktuell//index.html?SID=92WeCbQ6wQATQAABLWEO8a79e5784a88254b57cef01d59fc2909d#page_1048
06:26 AM IchGucksLive: its a simple CPC plug
06:29 AM RyanS: it is supplied with the cnc version of the plasma by default unfortunatly
06:30 AM RyanS: ii haven't built the cnc table yet
06:32 AM IchGucksLive: then you got a pinout of the cable
06:32 AM RyanS: i was thinking of neuron and uccnc,
06:32 AM IchGucksLive: i dont use the CNC version of my hyperterm 85
06:33 AM IchGucksLive: and on the price i like to use s.cutter
06:33 AM IchGucksLive: http://www.stamos-schweissgeraete.de/de/Plasmaschneider
06:34 AM IchGucksLive: 20screws to open and implement the THC
06:34 AM IchGucksLive: i use this one http://eagleplasma.com/torch-height-controls.html
06:35 AM RyanS: im not sure i have the intellectual horsepower to setup linuxcnc :-)
06:39 AM IchGucksLive: i can give you a full 7i76 setup
06:39 AM IchGucksLive: but it is so easy to use on pncconf
06:42 AM RyanS: i'm building a twin motor gantry so i think i need to install v2.8
06:42 AM IchGucksLive: no
06:42 AM IchGucksLive: on plasma it is not needed
06:42 AM IchGucksLive: no matter 0,2mm
06:43 AM RyanS: racking?
06:43 AM IchGucksLive: WHAT size are you going for
06:43 AM RyanS: 1200x1200mm
06:44 AM IchGucksLive: workplate
06:44 AM RyanS: yeah
06:44 AM IchGucksLive: are you using Ballscrews
06:45 AM IchGucksLive: or TR20x4
06:45 AM RyanS: rack and pinion probably
06:45 AM IchGucksLive: not at that size
06:46 AM IchGucksLive: it is to expensive as you need 30:1 gearing
06:46 AM IchGucksLive: YOU can go so cheep
06:47 AM IchGucksLive: as 20x4 TR spindle and the UCP204
06:47 AM IchGucksLive: then timingbelt
06:47 AM IchGucksLive: and you are up on 100USD
06:47 AM IchGucksLive: driven as normal 3Axis
06:48 AM IchGucksLive: no gantry at 8Nm Stepper
06:48 AM RyanS: r&p uses 5:1 i thought
06:48 AM IchGucksLive: 48V
06:48 AM IchGucksLive: UP to you
06:48 AM RyanS: 20x4?
06:49 AM IchGucksLive: i go 30:1 as 400steps Times 30= 12000Steps that meets Metric Rack pinion T10 Z12
06:49 AM IchGucksLive: as for 0,01 precision at 4800mm/min speed
06:50 AM IchGucksLive: RyanS: http://www.maedler.de/product/1643/1620/2028/2031/trapezgewinde-spindeln-eingaengig-rechts-stahl-laenge-15m
06:50 AM RyanS: not higher microstepping?
06:50 AM IchGucksLive: 25USD and nothing to do as drilling a 20mm Hole in a Timingbeltweehl
06:51 AM IchGucksLive: RyanS: You loos by EXP on microstepping force
06:51 AM IchGucksLive: and as the cable length you also loos speed
06:51 AM IchGucksLive: so go mechanical as far as you can
06:52 AM IchGucksLive: You do not need that precision at 0,01mm
06:52 AM IchGucksLive: and the TR20x4 gives you a real good start
06:53 AM IchGucksLive: You are in australia or
06:53 AM RyanS: yeah
06:53 AM IchGucksLive: where next mayor city
06:54 AM RyanS: melbourne
06:55 AM RyanS: no gantry ... so fixed gantry , moving table?
06:56 AM IchGucksLive: NO
06:56 AM IchGucksLive: moving the Torque
06:56 AM IchGucksLive: let me show you mine
06:57 AM IchGucksLive: th TR20x4 is 20AU¼
06:57 AM IchGucksLive: $
06:58 AM IchGucksLive: this is mine https://www.youtube.com/watch?v=W-24T2lqgH4
06:58 AM IchGucksLive: but it is 2500x1500 +5 cutarea
06:59 AM IchGucksLive: RyanS: this is yours https://www.youtube.com/watch?v=iNEj9MWGLgg
06:59 AM IchGucksLive: its a Very Cheep build
06:59 AM IchGucksLive: For Educations
07:00 AM IchGucksLive: this is the Driving electronics http://heimwerkermarkt-tretter.de/3achs_elek
07:00 AM IchGucksLive: 150USD including steppers
07:06 AM RyanS: so where are the rails on the small table?
07:06 AM IchGucksLive: RyanS: i can give you CAD files if you like but i need to go now
07:06 AM IchGucksLive: THe PIN on Side are the Rails
07:07 AM IchGucksLive: RyanS: please hit my nick twice for Querr
08:01 AM miss0r: thats pretty cheap i guess
08:05 AM archivist: one needs a large pinch of salt sometimes
10:08 AM Jymmm: Apologies for the small flood coming...
10:08 AM Jymmm: I can't decide on a folder naming convention for albums that have multiple discs, any suggestions?
10:08 AM Jymmm: Pink Floyd - Delicate Sound of Thunder - Disc 2
10:08 AM Jymmm: Pink Floyd - Delicate Sound of Thunder - 2of2
10:08 AM Jymmm: Pink Floyd - Delicate Sound of Thunder (Disc 2 of 2)
10:08 AM Jymmm: Pink Floyd - Delicate Sound of Thunder (2 of 2)
10:08 AM Jymmm: Pink Floyd - Delicate Sound of Thunder (2of2)
10:08 AM Jymmm: something else?
10:09 AM _methods: are you using any library software for your music?
10:09 AM _methods: like plex or mediamonkey or something?
10:10 AM _methods: subsonic?
10:10 AM Jymmm: No, pure OS/NAS FS
10:10 AM archivist: just make it descriptive
10:10 AM _methods: i guess it really doesn't matter then
10:11 AM _methods: some library packages are picky about naming conventions
10:11 AM Jymmm: _methods: how so?
10:11 AM _methods: but if it's just you, go with what you want
10:11 AM _methods: well some of them require a certain naming
10:11 AM Jymmm: I might later on use something, but right now just organizing them the best I can
10:11 AM Jymmm: _methods: such as?
10:12 AM _methods: depends on the software
10:12 AM _methods: you just need to look at their docs and see what they require
10:12 AM Jymmm: any examplw will do
10:12 AM _methods: one sec
10:12 AM Jymmm: k
10:12 AM _methods: https://support.plex.tv/hc/en-us/articles/200265296-Adding-Music-Media-From-Folders
10:12 AM archivist: even "Several Species of Small Furry Animals Gathered Together in a Cave and Grooving with a Pict" could come up with a naming convention
10:13 AM HighInBC: groovy tune
10:13 AM _methods: The folder containing the individual tracks for an album must be Artist_Name - Album_Name with the artist and album in that order.
10:14 AM Jymmm: _methods: That's fine, and what I have, except I've added (or atempting to) add the disc#
10:14 AM _methods: yeah i'd add a disc subfolder under the album
10:15 AM Jymmm: Yeah, I'm attempting to avoid the whole nesting too depply thing
10:15 AM _methods: artist name>album>disc>songs
10:15 AM Jymmm: and I don't use/avoid track# too
10:15 AM _methods: yeah
10:15 AM archivist: they all join up on old floyd
10:16 AM archivist: my uncle was on one of the albums
10:17 AM Jymmm: _methods: It looks ugly to see a song with "02_blah.mp3" instead of "/Artist - Album/Artist - Title.mp3"
10:17 AM _methods: yeah i honestly don't care as long as plex recognizes the song for me
10:17 AM _methods: or whatever player i'm using
10:18 AM Jymmm: _methods: Then, if I want only select songs, I toss them in artist folder, while maintaining the full albums in artist-album folders
10:18 AM _methods: yep
10:18 AM Jymmm: _methods: that's thething, I don't know what I'll be listening to them on, so not one sw specific.
10:19 AM _methods: well it's not really a big deal because there are plenty of programs that will rename it all for you
10:19 AM Jymmm: I have full flac of albumbs, but can transcode to mp3 if I want
10:20 AM Jymmm: _methods: It's organization, portability across platforms than I'm contending with, like avoiding certain puncuation (`)
10:22 AM Jymmm: _methods: I have empty folders with "D ------" as example so I can, at a glance, see where in the AZ level I'm at when scrollng through 40,000 songs
10:22 AM Jymmm: it works quite nicely
10:24 AM Jymmm: _methods: but this is fugly... https://imgur.com/a/WlTLN
10:24 AM _methods: yeah lol that's what happens when you collect music from all over
10:24 AM _methods: all that random tagging
10:24 AM Jymmm: _methods: various playlists
10:25 AM Jymmm: and lack of organization over years =)
10:25 AM _methods: you might want to take a look at beets.io if you're this into tagging and cleaning your mp3 library
10:26 AM Jymmm: _methods: anything like https://picard.musicbrainz.org/
10:26 AM _methods: yeah but better i think
10:27 AM _methods: i've used musicbrainz before too though
10:27 AM _methods: i use beets now though
10:27 AM Jymmm: beets says it uses musicbrainz db
10:27 AM Jymmm: smong others
10:28 AM Jymmm: _methods: ty for the link
10:28 AM _methods: sure np
10:28 AM _methods: anyone watching the news right now?
10:28 AM _methods: did something just happen?
10:28 AM _methods: stock market just did a nosedive for some reason
10:29 AM _methods: ah nm it looks like it picked back up
10:29 AM _methods: thought some craziness happened or something
10:29 AM HighInBC: probably something someone said on twitter
10:29 AM HighInBC: _someone_
10:29 AM Roguish: that's just a little irrational exhuberance
10:30 AM Jymmm: FUD FTW
10:30 AM Jymmm: FUD == Fear, Uncertainty, Doubt
10:31 AM Jymmm: Like saying "Hi Jack (long time no see)" on a plane
10:31 AM _methods: yeah that happens sometimes lol
10:31 AM Jymmm: FUD is always
10:32 AM Jymmm: _methods: You just experianced FUD when you thought something happened when there was a jump in the stock market.
10:32 AM _methods: yeah
10:32 AM _methods: well i'm rather surprised it's been going up like it has
10:33 AM _methods: i guess everyone is all giddy with prospects of war
10:33 AM _methods: all the guns bullets and tanks we'll be building in the near future
10:34 AM Todd_Z: bunkers, radiation suits...
10:37 AM _methods: all that consumption lol
10:37 AM _methods: caskets
11:21 AM Jymmm: _methods: big old ditches
11:21 AM Jymmm: _methods: save money, bury in bulk!
11:51 AM IchGucksLive: hi all :P
11:51 AM IchGucksLive: good tunar sandwitch this evening
11:52 AM IchGucksLive: RyanS: around ?
11:57 AM Loetmichel: *harhar* just came home from work. Wife would have bet i had forgotton our wedding anniversary. $me had 2 dep fried coalfish filets with potato salad (from her favourite fish booth) and a bouqet of 17 long stem roses behind my back. She was "blown away"... sometimes its so easy to be nice... (expensive nontheless ;)
12:09 PM BeachBumPete: Damn home sick from work today :(
12:09 PM _methods: lucky
12:09 PM BeachBumPete: hey methods
12:10 PM BeachBumPete: dunno about lucky no pay for missing work around here
12:10 PM IchGucksLive: hi BeachBumPete how does the world around you look after the storm's
12:10 PM * Jymmm FedEx One hour delivery 12 contagious diseases that don't have names yet.
12:10 PM Jymmm: ...to _methods
12:10 PM _methods: yeah send me some of that plague
12:11 PM BeachBumPete: Looks pretty much exactly as it did before the storms....minus a few roofing tiles
12:13 PM BeachBumPete: I really need to develop my 3D CAD CAM skills more jeez
12:14 PM _methods: do it
12:26 PM BeachBumPete: just had a friend who I worked with in Tennessee try to help me with some 3D toolpathing I needed to do. He sent me some files he did years ago that were similar to what I want to do. Shits WAAAYYYYY beyond my skills LOL
01:43 PM IchGucksLive: im off GN8 from germany
02:03 PM MrHindsight is now known as CaptHindsight
02:04 PM CaptHindsight: has anyone read the thread on the ML about MachineKit on the BeagleBone Black?
02:06 PM CaptHindsight: not sure why the guy that wants to rewrite the way config files are written and used since he considers them crap
02:25 PM CaptHindsight: never mind, Andy explains it in a recent post
02:26 PM CaptHindsight: the BBB is not covered by PnCConf or Stepconf so the guy is really just complaining about this
02:36 PM CaptHindsight: skunkworks: in that thread about the BBB, are they really just complaining about there not being a GUI to configure everything?
02:37 PM skunkworks: somewhat - it comes down to editing text files is bad in 2017
02:39 PM CaptHindsight: i guess life would be easier if you didn't have to machine anything either
02:40 PM CaptHindsight: all the parts are just off the shelf, you just bolt them together
02:42 PM _methods: wouldn't it be better if it just came all assembled in a box?
02:43 PM _methods: assembling stuff sounds a tad archaic
02:43 PM evilroot: Srsly
02:43 PM hazzy: I just don't get why in 2017 siri is not capable configuring LCNC. I mean, c'mon guys, it can write texts right? So why not text based config files? Get with it
02:43 PM pcw_mesa: I partly feel guilty because our stuff could be easier to configure, but then I get into the
02:43 PM pcw_mesa: "If you cant be bothered to understand how it works, maybe you should run something else" mood
02:43 PM evilroot: Real machines assemble themselves
02:43 PM evilroot: Then kill all humans
02:43 PM gloops: about every 2 weeks it comes up in the facebook diy cnc group - which control app has the best customisable interface lol
02:51 PM Tom_itx: CaptHindsight, what's it supposed to do in 2017... sense the attached hardware and just configure itself?
02:51 PM evilroot: "plug and play CNC"
02:52 PM Tom_itx: to an extent it could sense the mesa cards
02:55 PM hazzy: A Taylor Swift branded UPS truck just stopped by. Anybody else seeing those? Seems real out of character (for UPS)
02:55 PM hazzy: Looks like this: https://pbs.twimg.com/media/DJN_O4wVAAARgHE.jpg:large
02:56 PM _methods: these are dark days
02:56 PM hazzy: brown days ...
02:58 PM gloops: end days
02:58 PM pcw_mesa: Tom_itx: move the axis and listen for people yelling...
02:58 PM gloops: none of this matters because we'll all be dead soon and wont know anything about what hit us
03:32 PM gregcnc: I hate finding new junk drills in a good 115pc set I bought years ago.
03:33 PM andypugh: Binky!
03:33 PM andypugh: https://www.youtube.com/watch?v=hR1nU9IJsoM&feature=em-uploademail
03:38 PM skunkworks: Finally!
03:39 PM andypugh: They are actually getting better at what they do, and they started off good.
03:45 PM gregcnc: lol "was almost worth it"
03:58 PM evilroot: Blah
03:58 PM evilroot: Guess its time to tear this CMM down for parts
03:58 PM * evilroot hates killing perfectly good tools
04:00 PM hazzy: evilroot: Is nobody interested in it?
04:03 PM evilroot: Not that I've found
04:04 PM hazzy: I would be interested but at the moment I am rather poor. What would you be willing to part with it for?
04:08 PM JT-Shop: I think it is close enough to 5 o`clock at my sisters house to have my beer with the chickens
04:09 PM Phipliv: What is their tipple of choice?
04:09 PM JT-Shop: today we are slumming with a Corona and a splash of lime
04:10 PM Phipliv: Mine prefer dew drops and puddle water
04:10 PM JT-Shop: how's things on your side of the pond
04:10 PM JT-Shop: dang chickens jump in my lap and go to sleep now unless they are on my head
04:11 PM Phipliv: Sleepy. Worked two 11 hour nights plus other bits and bobs
04:11 PM MarcelineVQ: geeze that bracket they made took a long ass time, but it sure looks good
04:12 PM JT-Shop: I'm putting a POE switch in the coop so I can have a few cameras out in the woods
04:12 PM Phipliv: made a train slide on soap
04:12 PM Phipliv: tested some sand...
04:12 PM Phipliv: didn't see the birds much
04:13 PM Phipliv: met a railway depot cat that liked snoozing on a driveshaft rack
04:13 PM MarcelineVQ: what were you testing the sand for?
04:14 PM andypugh: Flammability?
04:14 PM Phipliv: we use sand as a traction modifier - spray it under the wheels when they slip
04:14 PM JT-Shop: I have a new friend his name is Chip and he/she is not afraid of me at all just keeps still when I get close
04:14 PM Phipliv: someone wants to sell us magic extra grip sand
04:15 PM Phipliv: What type of creature is Chip?
04:15 PM JT-Shop: school busses in Alaska have sand hoppers in front of the rear wheels
04:15 PM JT-Shop: chipmunk
04:15 PM JT-Shop: he stuffs his face full of sunflower seeds
04:15 PM gloops: http://www.ebay.co.uk/itm/Butler-Elgamill-CS10-6-Metre-Universal-Bedtype-Milling-Machine-/202072991414?
04:15 PM gloops: 6 metre bed, thats pretty big
04:16 PM Phipliv: JT-Shop : interesting - we use an airbrush like system to spray it
04:16 PM CaptHindsight: Tom_itx: what that guy really wants
04:16 PM CaptHindsight: but andypugh had good responses about the situation
04:16 PM JT-Shop: IIRC and that was a very long time ago the driver had a knob that he could pull and start letting sand out
04:16 PM Deejay: gn8
04:17 PM Phipliv: JT-Shop : have a picture of Chip?
04:17 PM Phipliv: Night Deejay
04:17 PM CaptHindsight: Phipliv: the CNC penguin?
04:17 PM JT-Shop: no, but he will sit still for one I'm sure... I just never have my phone in my pocket lol
04:18 PM CaptHindsight: oh JT's chip
04:18 PM Phipliv: CaptHindsight : JTs new friendly neighbourhood chipmunk
04:18 PM Phipliv: yeah
04:18 PM Phipliv: (Slow phone typing)
04:19 PM andypugh: I saw a chipmunk running along the infield wall of the Las Vegas Motor Speedway. Seemed a bad place for a Chipmunk to live.
04:19 PM Phipliv: Perhaps it was a motorsport fan?
04:19 PM andypugh: Elgamills are cool: http://www.lathes.co.uk/elgamill/
04:19 PM CaptHindsight: JT-Shop: I never looked at the inner working of PnCConf, is it all in Python?
04:20 PM JT-Shop: part Glade IIRC yea python
04:20 PM JT-Shop: but I think Chris uses an old version of Glade like Ubuntu 8 or something
04:21 PM JT-Shop: chicken time, talk to you guys later
04:22 PM Phipliv: see you
04:23 PM andypugh: And the factory is still open and is near my sister’s house: https://goo.gl/maps/ATvWBAJnbSG2
04:24 PM CaptHindsight: heh machinekit has it's own pncconf
04:25 PM CaptHindsight: so why all the complaining?
04:25 PM CaptHindsight: https://github.com/machinekit/machinekit/blob/master/src/emc/usr_intf/pncconf/pncconf.py
04:25 PM CaptHindsight: unless it's just a copy of what's in LCNC
04:26 PM cradek: of course it is
04:26 PM CaptHindsight: heh
04:26 PM andypugh: They could modify it to use the PRU, if they could be bothered.
04:27 PM andypugh: (I get annoyed when we end up copping flak for Machinekit’s poor support)
04:27 PM CaptHindsight: cradek: so how close are you guys to having Linuxcnc just configure itself by just snapping a picture of your parts? :)
04:29 PM CaptHindsight: the other way around is to have a kit of parts that go with configs on the LiveCD ...
04:30 PM CaptHindsight: someone like Automation Technologies could easily do so
04:30 PM andypugh: I don’t think what he wants is unachievable, impossible or even undesirable. I just don’t think that we have a big enough team to do it and maintain it.
04:31 PM andypugh: Also, there seems to be a belief that we care if LinuxCNC “takes off” or not.
04:31 PM skunkworks: heh
04:32 PM CaptHindsight: well a version that spys on you could become popular, if you wanted to go that way
04:33 PM hazzy: Ok, quick question. I put a 1 hp VFD on my PB, which draws about 9A peak @ 240V.
04:33 PM hazzy: I am trying to decide how best to switch the power to the VFD
04:33 PM hazzy: Would it be very inadvisable to simply feed the VFD thru the Estop?
04:33 PM andypugh: Yes.
04:34 PM cradek: estop should not remove power from the vfd
04:34 PM hazzy: Or should I really add a relay and have the estop switch that?
04:34 PM cradek: for one thing, it can't brake then
04:34 PM hazzy: ok
04:34 PM cradek: the vfd should have connections for this
04:34 PM hazzy: So estop should just tell the VFD to stop
04:35 PM andypugh: I would (and do) connect through one of these: http://www.ebay.co.uk/itm/Solid-State-Relay-Module-SSR-25DA-25A-3-32V-DC-to-24-380V-AC-With-safety-Cover-/162610535630?var=&hash=item25dc57dcce:g:-GAAAOSwEgZZfdol
04:35 PM CaptHindsight: unless when the VFD loses power it dumps the motor power into a resistor
04:37 PM andypugh: Here are a bunch of names from the past, from the Butler Elgamill page at lathes.co.uk “Butler Elgamill CSN10 with a choice of CNC controls: Plessey NC11, NC22 and NC33; Cincinnati Acramatic 1V and V and Bendix 400 and 1500 (others could be fitted as well. “
04:37 PM hazzy: the SSR is a good idea. But then I need a low voltage supply as well. Which complicates things
04:38 PM andypugh: You can control them from whatever you are using for everything else.
04:39 PM andypugh: They don’t take much control current.
04:40 PM hazzy: This is a manual machine, so there is not much else! But it is right next to the CNC. maybe piggy off that logic supply :D
04:40 PM andypugh: Ah, gloops left. I was going to tell him to buy the Elgamill, the auction photos do not do the machine justice. My dad used to go into raptures about the one at David Brown,
04:41 PM andypugh: hazzy: I bet the VFD itself has a suitable supply. Oh, wait, no, that’s a bootstrap problem :-)
04:41 PM CaptHindsight: hazzy: $2 12V power supply
04:41 PM andypugh: 9V battery…
04:42 PM CaptHindsight: have you seen the recent price of 9V batteries? :)
04:43 PM andypugh: The other week I bought a soldering iron to repair a fuse. The soldering iron was cheaper than a 60A fuse.
04:43 PM andypugh: (This is because the actual fuse was a ZCASE and those don’t appear to be sold in shops)
04:44 PM skunkworks: our 2000 vintage fridge had a fuse blow. Soldered on the main circuit board. (made one - and it has been running ever since..) Knock on wood
04:44 PM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/cnc-router/kl-1325-cnc-machine/ $9500
04:44 PM skunkworks: actually it is probably 2010ish
04:45 PM CaptHindsight: how much work to get this running square and lash free?
04:45 PM CaptHindsight: oh and reliable
04:46 PM skunkworks: it was the fuse that was inline with the compressor... Really thought the compressor locked up
04:46 PM CaptHindsight: is the table and gantry even square?
04:50 PM CaptHindsight: https://www.automationtechnologiesinc.com/wp-content/uploads/2013/02/KL-1325E.jpg the rack and pinions already look old
04:51 PM CaptHindsight: crud on the casting below
04:52 PM andypugh: I am quite impressed with this machine. https://photos.app.goo.gl/gw3PW583icysgTAH3
04:53 PM andypugh: That would be could for T
04:54 PM andypugh: … RTAI but that’s the PREEMPT-RT ISO with no tweaks or anything.
04:54 PM CaptHindsight: andypugh: the all in one PC?
04:54 PM andypugh: Yes
04:54 PM CaptHindsight: yes, was surprised
04:54 PM CaptHindsight: are there many options in the BIOS?
04:54 PM CaptHindsight: often they strip everything out
04:55 PM andypugh: There are. But I haven’t touched them.
04:55 PM CaptHindsight: we had some HP machines that didn't let you kill power management
04:55 PM andypugh: It’s got a fancy USB-mouse aware graphical BIOS.
05:02 PM CaptHindsight: I need an oven that is ~50" x 30" by only 6-8" deep
05:03 PM andypugh: Make one?
05:03 PM CaptHindsight: cure power coated sheet, yeah
05:03 PM CaptHindsight: powder
05:04 PM andypugh: Generic element inside a laser-cut and folded box.
05:04 PM CaptHindsight: would cool off quick if the door is the 50 x 30 side
05:09 PM CaptHindsight: https://cdn3.volusion.com/qqaat.ueagw/v/vspfiles/photos/RAL-4.jpg maybe hinged like this, only flipped 90 deg
05:09 PM andypugh: Is that good or bad?
05:10 PM andypugh: (queston about previous comment)
05:10 PM CaptHindsight: good as long as you don't open the door when it's curing
05:11 PM CaptHindsight: ramp time up/down doesn't matter much for powder coatings
06:11 PM gloops: i suppose the mundane subject of how to make hard cash from diy cnc must be raised sometime
06:15 PM gloops: a casual glance at the marketplace fills one with sadness and apprehension over mankinds future
06:16 PM gloops: the items that sell are largely pointless baubles and personalised decor
06:16 PM gloops: i.e not interesting to make
06:16 PM evilroot: Fidget spinners!
06:16 PM andypugh: I think that the LinuxCNC devs (for example) knew from the start that trying to make cash from DIY CNC was a non-starter.
06:17 PM gloops: well, yes there are those
06:17 PM evilroot: Well a lot of things you don't even realized were done with CNC
06:17 PM MarcelineVQ: gloops: the prices of woodworks on etsy are mindboggling, I wonder how many people actually sell, if any do there's a killing to be made
06:17 PM evilroot: Personally I intend to use my CNC bots to build 3D printers
06:18 PM evilroot: Which god knows there's a market for
06:18 PM andypugh: gloops: Were you interested in that Elgamill? They are very good machines and the pictures in that auction do the machine no favouurs.
06:18 PM gloops: Marceline yes, nail a bit of driftwood to something and charging $500 seems to be the way to go
06:18 PM sync: it is called art
06:19 PM evilroot: Etsy is absurd to start with
06:19 PM MarcelineVQ: ehe, well I​ meant somehting a little nicer like a cnc carved pieces with some handwork at the end for flavor, but there's lots of that driftwood nonsense too
06:19 PM gloops: andypugh - no was only looking at the tooling the seller had listed, noticed the mill afterwards - not something i could house really
06:19 PM gloops: agree re the photos
06:20 PM CaptHindsight: hobbies aren't mainstream anymore, it's been decades
06:20 PM gloops: evilroot thats probably the best line - selling diy machines or components
06:21 PM evilroot: One of the coolest things I saw being done was a guy making titanium chopsticks
06:21 PM evilroot: On his CNC lathe
06:21 PM evilroot: Now THAT was cool
06:21 PM CaptHindsight: Automation technologies sells ChinaCo machines refitted with Mach
06:21 PM CaptHindsight: he does ok selling them
06:22 PM evilroot: Psh, instead you should buy a robot from me :-D
06:22 PM gloops: funny thing really, how control of the means of production runs away with cnc
06:22 PM evilroot: Though mine aren't that big
06:22 PM gloops: i mean, you could never really make another lathe - on your lathe
06:23 PM gloops: that isnt the case with cnc
06:23 PM evilroot: Same with 3D printers
06:24 PM gloops: its like a revival of the cottage industry
06:24 PM gloops: people making stuff in their own homes, to sell or under franchise etc
06:25 PM CaptHindsight: CNC gadgets that make things like pizza or pancakes might get some funding if it also spys on you
06:26 PM CaptHindsight: there a local entrepreneur space in Chicago, it's like a makerspace for people going into business
06:26 PM gloops: it will all eventually become incorporated into one personal machine that does everything
06:26 PM CaptHindsight: works similar, you rent a small private area but the rest is all shared
06:27 PM gloops: thats a good idea
06:27 PM CaptHindsight: when I looked at what gets funded it was mostly software that people volunteer to buy that spies on them
06:28 PM gloops: excellent
06:28 PM CaptHindsight: the trick is finding an app that everyone wants
06:28 PM CaptHindsight: like this one app the you take pictures of yourself or friends with a product and they pay you a small amount for uploading it
06:29 PM CaptHindsight: pennies per pic
06:30 PM gloops: everyone seems dependent on getting likes for pics on social media
06:30 PM evilroot: Is there an app where Russia will pay you for liking white supremacist stuff?
06:30 PM gloops: if you had a social app with millions of bots that like everyones pics and gives them loads of attention, it would be a winner
06:30 PM evilroot: Seems like there must be
06:32 PM gloops: who knows, russia has a very subversive foreign policy
06:33 PM CaptHindsight: evilroot: maybe in likes
06:34 PM CaptHindsight: the point is that people line up to use your app that spies on them
06:34 PM CaptHindsight: that is gold right now, and has been
06:34 PM gloops: well, the alternative is an app that people want out of fear
06:35 PM CaptHindsight: use it or else?
06:36 PM gloops: yes, must have life saving, or personal image saving thing
06:37 PM gloops: tells you when you are entering an area with a high mugging rate, how safe your car is parked in this location, how many people died of food poisoning from that restaurant
06:38 PM CaptHindsight: and spies on you
06:38 PM gloops: gives you a psychological profile of all your friends based on their facebook posts
06:39 PM gloops: well, Capt, the obvious tried and tested medium for a surveillance app - is...a surveillance app
06:40 PM CaptHindsight: sells your info and habits to marketers
06:40 PM CaptHindsight: why I strap my phone to a cat every night
06:43 PM gloops: probably too late to be anonymous
06:44 PM CaptHindsight: nah just fun data
06:47 PM CaptHindsight: I'm looking at what might be the lowest cost hardware to read encoders and feed position to LCNC
06:48 PM CaptHindsight: over USB or Ethernet
06:48 PM andypugh: How muxh work are you prepared to do?
06:48 PM CaptHindsight: to be able to use LCNC as the readout on manual machines
06:49 PM CaptHindsight: Teensy is $20
06:49 PM CaptHindsight: and can count ~20K/sec
06:50 PM andypugh: Something like the motion-focussed STM32 would work, bout would need boards and such.
06:50 PM CaptHindsight: works over USB with TeensyHAL
06:50 PM CaptHindsight: yeah looking at stm32
06:50 PM CaptHindsight: https://github.com/andysworkshop/stm32plus ethernet stack
06:50 PM andypugh: Maybe an STMBL board without the expensive bits :-) Encoders/resolvers to smart-serial
06:51 PM sync: no
06:51 PM sync: the hardware is already done
06:51 PM sync: and the code also, basically
06:51 PM CaptHindsight: http://pekka.eu/cnc/ did it with stm32
06:51 PM sync: the netbob does exactly this
06:51 PM CaptHindsight: netbob?
06:53 PM sync: some hardware we designed
06:54 PM sync: stm32f407 + ksz8081
06:54 PM sync: talks the mesa protocol over ethernet
06:55 PM MrHindsight: all on one board called the netbob?
06:57 PM MrHindsight: http://www.st.com/en/evaluation-tools/stm32f4discovery.html
06:57 PM sync: we're doing everything through DMA so the cpu load is virtually 0%
06:59 PM MrHindsight: that board is the same price as the Teensy
07:00 PM MrHindsight: USB should be fast enough
07:01 PM MrHindsight: stm32 HAL is needed
07:07 PM MrHindsight: https://www.aliexpress.com/store/product/Free-shipping-xilinx-fpga-development-board-spartan-6-xilinx-board-xilinx-xc6slx9-tqg144-fpga-development-board/620372_32665068263.html
07:08 PM MrHindsight: this could read encoders much faster
07:08 PM MrHindsight: $24 plus shipping
07:14 PM MrHindsight: http://www.micromouseonline.com/2013/02/16/quadrature-encoders-with-the-stm32f4/
07:50 PM MarcelineVQ: I probably can't get the chip by itself for that price here
08:45 PM Tom_itx: somebody looking for a STM32F4 discovery board?
09:56 PM Crom: Tom_itx: nope got mine right here
11:13 PM RyanS: is there a way to make a bootable usb of linuxcnc live io from windows? i tried unetbootin, but i get "debconf... can't open display
11:14 PM RyanS: #offtoagreatstart
11:15 PM hazzy: RyanS: yes
11:15 PM hazzy: I use Rufus
11:15 PM hazzy: https://rufus.akeo.ie/
11:22 PM nullifier: Anyone play w/ leadshine amplifiers before?
11:23 PM hazzy: nullifier: I have used their hybrid servo drives
11:28 PM Tom_itx: rufus would probably work. i've used it for other things
11:29 PM RyanS: hazzy: a sytem shouldn't loose steps if properly matched. are there other advantages to easyservos?
11:30 PM RyanS: i've heard better torque curve, cooler running etc
11:32 PM RyanS: re rufus. which partition scheme & file system should i use?
11:34 PM hazzy: RyanS: I have always used the defaults
11:35 PM RyanS: ok thanks
11:37 PM hazzy: and if you even need to make a bootable USB on a linux machine, Etcher is very covenant
11:37 PM hazzy: I guess etcher could also be used on Windoze instead of Rufus
11:37 PM hazzy: https://etcher.io/
11:37 PM MarcelineVQ: your system comes with dd so on linux you're in good shape
11:38 PM MrHindsight: http://www.motioncontroltips.com/faq-whats-the-difference-between-servo-and-closed-loop-stepper-motors/
11:38 PM hazzy: this is true
11:38 PM MrHindsight: what is this weendoze?
11:39 PM hazzy: It is something you throw out the windows as fast as you can
11:39 PM RyanS: a linux religion ?
11:39 PM hazzy: You will be converted too, once you use Linux for a while :D
11:40 PM nullifier: hazzy: Hybrid, so the MD series?
11:41 PM nullifier: I have a pair of ACS606s, and motors w/ no halls... is a little bizarre to me that they would require them for a 2000 ppr encoder
11:41 PM RyanS: i'm only enduring linux for a cnc plasma build :-)
11:42 PM nullifier: learn basic navigation and how to find things
11:42 PM hazzy: nullifier: Mine are the HSB series, really stepper drives with an encoder and some PID added in
11:42 PM nullifier: because 'nix is everywhere you look
11:42 PM XXCoder: even behind you
11:42 PM hazzy: RyanS: this was what I said too!
11:43 PM nullifier: Ah... damn. I am absolutely lost on how to configure them without the halls
11:43 PM RyanS: any point in closed loop steppers for plasma?
11:44 PM nullifier: EDM yes, plasma no
11:44 PM hazzy: Yes, I would say so. The main advantage is higher speed
11:44 PM hazzy: For plasma you need high speed a lot of times
11:45 PM XXCoder: why would closed loop grant higher speed
11:45 PM nullifier: because encoders add torque!
11:45 PM nullifier: +70hp
11:46 PM hazzy: Because the drive knows exactly were the rotor is and can push it just to the point of not skipping a step
11:46 PM hazzy: With regulare steppers you have to be vert conservative because you can miss steps
11:46 PM XXCoder: there is that
11:46 PM MarcelineVQ: your load doesn't really change with plasma so losing steps hopefully won't come up once you're dialed in, fingers crossed
11:47 PM nullifier: these ACS drives use a TI MSP430
11:47 PM RyanS: i have powermax 45xp, highest cut speed reqiured = 7.9m/s
11:47 PM hazzy: But you normally lose steps in rapids, not at feed speeds
11:47 PM MarcelineVQ: dat's fast :o
11:47 PM RyanS: is that quick ?
11:47 PM nullifier: they tried to sand off the chip marking but didn't go deep enough
11:48 PM nullifier: that's blinding
11:48 PM nullifier: if you got hit by an armature moving that fast it would knock you into next week
11:48 PM hazzy: That is scary fast
11:48 PM nullifier: it might even pinkmistify you
11:49 PM RyanS: sure. and the real answer? :-)
11:49 PM hazzy: actually it might knock you out till next week
11:49 PM nullifier: I mean gantry not armature
11:49 PM nullifier: or table
11:50 PM nullifier: Vector, damnit.
11:50 PM hazzy: I was wondering ...
11:50 PM nullifier: Servo on brain
11:51 PM RyanS: no, 7.9m/min, not seconds <facepalm>
11:51 PM nullifier: Why did weller make every single pencil plug in different
11:51 PM MarcelineVQ: RyanS: that's quite a bit more nice
11:51 PM nullifier: Oh... uh. Yeah. That's a bit slower.
11:51 PM hazzy: much better
11:51 PM nullifier: You could dodge that. Grandma could dodge that actually.
11:52 PM hazzy: That is slow
11:52 PM nullifier: 1.3cm/s
11:52 PM nullifier: for 90
11:52 PM hazzy: My little mill does 300ipm on Z
11:52 PM nullifier: hazzy did you buy yours from leadshine or fleabay
11:53 PM hazzy: Neither, I bought direct from china
11:53 PM nullifier: I'm a pittle list off because nowhere does it specify halls required on anything they have for a datasheet.
11:53 PM nullifier: it says accepted
11:54 PM nullifier: they expect you to use their motor, which is silly
11:55 PM hazzy: that is silly. All you need it the drive?
11:55 PM nullifier: Yep. I have differential AB/Zind encoder output @ +-5V
11:56 PM hazzy: I really like the Advanced Motion Tech servo drives
11:56 PM RyanS: IchGurkslive was saying i should use a single trapezoid in the middle of the gantry. i don't really know, but i think it'll have racking issues
11:56 PM nullifier: I know the phases, marked up nice... am sure of them, but it alarms as though no encoder is connected. I can assume because no halls.
11:56 PM RyanS: 1200x1200mm table
11:57 PM nullifier: I have 2x 3100mm gantries
11:57 PM nullifier: and associated ballscrews from a PNP
11:57 PM * hazzy shuts down the mill and heads for bed
11:57 PM nullifier: rails, thk linear... but damnit I cannot talk to these drives
11:57 PM hazzy: gn8
11:58 PM nullifier: the big ones, and the ACS... halls missing
11:58 PM nullifier: night hazzy
