12:08 AM Jymmm: Um, 9v battery in a pile of metal swarf is probably not a good thing =)
12:09 AM Jymmm: pink_vampire: and what are you doing with a 9ft long match stick?
12:09 AM Wolf__: doesn’t that nut short out the path on those balls
12:09 AM Jymmm: Wolf__: It's a non conductive metalic nut silly
12:10 AM Wolf__: oh right, I have lots of that
12:10 AM pink_vampire: it was a test
12:14 AM Jymmm: Done... https://i.imgur.com/eOx8JYc.jpg
12:15 AM Wolf__: pre or post reg?
12:16 AM Wolf__: nm that would have to be post reg
12:16 AM Jymmm: post main 250gal tank reg
12:17 AM Jymmm: Which kinda sucks, sorta
12:17 AM Wolf__: pressure/flow drop on anything high draw
12:18 AM Jymmm: There are regualtors on the gen and heater, so the double reg doesn't work
12:18 AM Wolf__: yeah
12:21 AM Jymmm: I really dont liek the idea that I can't use bbq tanks if I remove the regulators
12:21 AM Jymmm: But I have male and female acme connectors, so I'll toss a regulator between them and use as an adapter, I guess.

03:02 AM Deejay: moin
03:29 AM pink_vampire: hi
04:28 AM XXCoder: yo
04:35 AM pink_vampire: hi XXCoder
04:35 AM XXCoder: record breaking for march hot here
04:35 AM XXCoder: 73f jeez
04:44 AM pink_vampire: here is cold again
04:49 AM XXCoder: by friday it'll be back to 50s f normal for late winter
04:49 AM XXCoder: but 73f worry me
04:49 AM XXCoder: summer may well be recordbuster
04:58 AM jthornton: morning
05:17 AM pink_vampire: hi jthornton
05:19 AM XXCoder: hey jthornton recordbreaking temperate here heh
05:19 AM XXCoder: was 73f
05:19 AM jthornton: ours are pretty normal for this time of year
05:19 AM jthornton: morning pink_vampire
05:20 AM pink_vampire: https://www.youtube.com/watch?v=rAh_YFhH_V8
05:20 AM XXCoder: first record since 1940s snow, then now record hottest march ever
05:21 AM pink_vampire: look very interesting video
05:25 AM XXCoder: lol
05:25 AM XXCoder: linkedin recommanded me machinist job at company i work at.. as machinist
05:28 AM sensille: so you're in the best possible position already :)
05:28 AM XXCoder: unless its to replace me lol
05:29 AM XXCoder: from linked in message: "If you're interested in exploring how your existing passenger data can achieve the same results for your airline, visit our website."
05:29 AM XXCoder: yeah where is my airline dammit
05:32 AM SpeedEvil is now known as Guest17032
05:32 AM pink_vampire: i need an idea
05:32 AM XXCoder: what kind of idea?
05:33 AM pink_vampire: how to make super small core for a probe
05:33 AM jthornton: I used to get asked how long will it take to develop this and my answer was how long does it take to come up with an idea?
05:35 AM XXCoder: not sure what "core" is. is it inside part with 3 pins and where spring presses on it?
05:35 AM weenerdog: howdy
05:35 AM XXCoder: hey
05:35 AM pink_vampire: i also want it with metal m2 thread in the middle
05:35 AM weenerdog: sup
05:35 AM Tom_L: morning
05:35 AM pink_vampire: hi weenerdog
05:35 AM XXCoder: probably best with lathe?
05:35 AM XXCoder: then use 6 sided block to drill 3 holes for pins
05:37 AM pink_vampire: but you cant use conductive material
05:39 AM Tom_L: pink_vampire, http://fadedbits.com/2011/02/touchprobe/
05:39 AM Tom_L: size it down
05:39 AM Tom_L: http://www.vinland.com/Touch-Probe.html
05:41 AM pink_vampire: Tom_L: "three 0.125? steel dowel pins pressed into"
05:42 AM Tom_L: size it down
05:42 AM pink_vampire: it will be very difficult to scale down press fit and also get it very stiff
05:43 AM Tom_L: what size are you looking for?
05:43 AM Tom_L: sub micron?
05:43 AM pink_vampire: total OD 12mm
05:44 AM pink_vampire: with 1/8" shank
05:44 AM Tom_L: so now you have your idea
05:44 AM Tom_L: run with it
05:45 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/emc/small_probe3.jpg
05:45 AM Tom_L: i made a few different ones
05:46 AM Tom_L: https://www.carbideprobes.com/
05:46 AM Tom_L: probe tips
05:47 AM pink_vampire: what is the OD of the body for the smaller probe you made?
05:47 AM Tom_L: i don't remember
05:48 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/emc/small_probe4.jpg
05:48 AM Tom_L: the mat is 2" squares
05:51 AM pink_vampire: so it is about what i have now
05:57 AM pink_vampire: https://i.imgur.com/Q73eAKv.png
05:58 AM XXCoder: i want to make a probe, but it have to be very unusual design :(
05:58 AM pink_vampire: XXCoder: ?
05:59 AM pink_vampire: what kind of a design?
05:59 AM XXCoder: my cnc router is very shallow
05:59 AM XXCoder: which means probe body must be short
06:02 AM pink_vampire: mmm maybe all you need is to mount next to the spindle
06:02 AM Tom_L: use a last word indicator tip for starters
06:02 AM XXCoder: eh kinda dont wanna calculate offsets, but maybe
06:04 AM XXCoder: for a while point is kinda moot, no space to run machine :(
06:05 AM pink_vampire: what is your Z travel from the spindle to the top of the material?
06:05 AM XXCoder: 2 inches lol
06:05 AM pink_vampire: 2" is fine
06:06 AM XXCoder: the shorter the probe is, the higher part i can probe
06:06 AM XXCoder: i want to try curved surface engrave :)
06:07 AM pink_vampire: maybe piazzo electrical probe?
06:07 AM XXCoder: isnt that require conductive material?
06:08 AM pink_vampire: no
06:11 AM XXCoder: interesting
06:15 AM XXCoder: i read news about myspace losing 50 million songs. my first thought: "myspace still exists?" lol
06:16 AM * Loetmichel just went to the city office, registered the new old car... MAAAN is that insurance expensive in germany... 900 eur a year for a 2001 BMW 525i wagon. but it drives well. so i am happy ;)
06:16 AM XXCoder: that insurance is cheaper than mine
06:17 AM XXCoder: mines bit over $100 usd a month
06:17 AM XXCoder: but then mine is 2012 car lol
06:17 AM Loetmichel: only for others, doesent pay for glass or own damage, no idea what thats called in english
06:17 AM XXCoder: libility only
06:17 AM Loetmichel: the basic mandatory insurance
06:17 AM XXCoder: yeah mines full
06:18 AM pink_vampire: XXCoder: https://www.youtube.com/watch?v=o5Gl6YCrA8U
06:18 AM XXCoder: with that my cnc router can probe surface ;)
06:18 AM XXCoder: with no stock
06:18 AM XXCoder: but interesting
06:19 AM Loetmichel: i bought the car for 2100 eur. by the time its 2 year road legal test expires it will have cost me more in insurance and tax than i bought it ;)
06:19 AM XXCoder: z only probing may be useful for some uses.
06:19 AM XXCoder: not bad idea hmm
07:13 AM Elmo40: Loetmichel, that is always the method.
07:13 AM Elmo40: purchasing the car is the least expensive payment in owning a car!
07:14 AM Elmo40: insurance and repairs and fuel. that will out cost the price of any vehicle.
07:16 AM Loetmichel: Elmo40: its a 2001 car. it was to be expected
07:17 AM Loetmichel: but i didnt think its liability insurance would be quite THAT high
07:17 AM Loetmichel: its not the classic "kids first car" after all
07:25 AM Elmo40: does anyone use ncedit or ncview. i don't remember what it is called now. i used it ~10 years ago to view gcode files as a tool path
07:25 AM Elmo40: very lightweight program, allows you to edit the code on the spot and you see the new tool path.
07:56 AM rmu: Loetmichel: a 15year+ BMW somethingsomething with too much PS _is_ a typical kids first (and often last) car around here.
08:01 AM Loetmichel: rmu: true
08:01 AM Loetmichel: but usually the 3 series
08:01 AM Loetmichel: not the 5 series
08:02 AM Loetmichel: and not the station wagon ;)
08:40 AM BitEvil_ is now known as speedevil

09:31 AM Deejay: re
11:04 AM Loetmichel: gnhihi, i like that MoI "cad"... took me about an hour to learn how to do a mailbox lock in it with virtually no knowledge how 3d design works... its already printing ;)
11:09 AM Loetmichel: ... what i like about 3dprinting is that the idea->tangible result is so fast... about 1 hour of design, 18 min print and i will know it that thing fits into the paper towel spender ;)
11:46 AM Loetmichel: *NIIICE* fits first try... i like it when a plan comes together:-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=17334&g2_imageViewsIndex=1
12:00 PM rmu: Loetmichel: https://youtu.be/wyz_2DEah4o?t=8
12:01 PM Loetmichel: rmu: thats where that quote is from, indeed
12:22 PM Tom_L: sounds like Loetmichel didn't do his homework before geting a car
01:04 PM Loetmichel: Tom_L: hmm?
01:04 PM Loetmichel: why do you think that?
01:05 PM Loetmichel: you mean because i was surprised HOW expensive the insurance is?
01:05 PM Loetmichel: i knew it would be expensive, i just didnt expect it to be THAT much
01:06 PM Loetmichel: in hindsight its reasonable thoug. i pay ~600 a year for the Omega, BUT that is registered by my wife which has the maximum 65% discount because of 8 years or more no accidents.
01:06 PM Loetmichel: +h
01:07 PM Loetmichel: s/by/to
01:12 PM Wolf__: my one truck is $1600usd/yr for insurance
01:16 PM Loetmichel: Wolf__: only liability though here
01:17 PM Wolf__: thats $1mil liability and full replacement on $80k truck
01:24 PM Wolf__: my car is around $700/yr full coverage =)
01:26 PM Loetmichel: yeah, in germany is expensive to own a car
01:26 PM Loetmichel: :-)
02:33 PM pink_vampire: hi everyone
02:41 PM a-u: howdy
02:59 PM XXCoder: yo
03:00 PM pink_vampire: hi XXCoder & a-u
03:05 PM * jym rubs against pink_vampire... what about me???
03:05 PM XXCoder: i wouldnt do that she has mafia friends
03:05 PM XXCoder: one should be tapping your shoulder soon jym
03:05 PM pink_vampire: LOL
03:06 PM pink_vampire: jym: don't take it to crazy, i just login from this computer
03:08 PM gregcnc: polish mafia?
03:09 PM jym: pink_vampire: crazy? how?
03:09 PM * jym nods at gregcnc
03:09 PM jym is now known as jymmm
03:09 PM gregcnc: anyone use industrialmetalsales.com for aluminum?
03:10 PM a-u: yes - but it was some years back -- found other suppliers since
03:10 PM gregcnc: why did you switch?
03:11 PM pink_vampire: I got stuff from onlinemetals.com
03:12 PM gregcnc: jymmm is it warming up over there?
03:12 PM a-u: I believe the order was good, UPS shipping was OK - almost certainly it was price.
03:12 PM gregcnc: it's the cheapest I've found
03:12 PM jymmm: gregcnc: Actually yes, in tshirt and sandls today, warmest day so far =)
03:13 PM gregcnc: for small 6061 rounds
03:13 PM gloops: scrap ally is everywhere
03:14 PM gregcnc: gloops I don't need swarf?
03:14 PM gloops: cast your own gregcnc
03:14 PM gregcnc: fuck that
03:15 PM gregcnc: i making product not scrap
03:15 PM a-u: Lowest price seems the main thing. Right - or put in a foundry and recycle local scrap - lol.
03:15 PM gloops: haha, dont tell me youre one of these metalworkers that doesnt like fire?
03:15 PM pink_vampire: for aluminum i like the 2024-t3 over the 6061
03:16 PM gregcnc: my parts are small, but local sources are pretty high
03:16 PM gloops: well, a gingery type furnace - melt a kilo or 2 at a time
03:17 PM gloops: i dunno what the application is, but you cant get better than free blanks
03:20 PM gregcnc: really? even if I was making castings, I'd buy real ingots vs cutting up engine blocks or whatever
03:20 PM XXCoder: for professional parts i wouldnt be using scrap melt and casting. more 'mystery' metal in those
03:20 PM methods_: random aluminum lol
03:21 PM gregcnc: grade 123456....
03:21 PM methods_: 60615052
03:21 PM XXCoder: parts made in shop i work at some of em require certified materials also. which expire in a year.
03:21 PM gloops: you dont have to use crappy engine castings when there are plenty of pop cans around
03:22 PM jymmm: pop cans have a higher value recycled then repurposed
03:22 PM gregcnc: how much do you pay yourself to pick cans off the street?
03:22 PM gloops: well the chinese seem to get by using them
03:22 PM XXCoder: sadly shop really screwed up, they expected to be able to make those specific parts so order toooons of alum blocks. then oops cant make those parts
03:22 PM methods_: you don't have an army of crack heads you pay to collect cans for you?
03:23 PM XXCoder: year later material certification expired. so we have so many blocks ready for usage as making test parts or fixture or whatever.
03:23 PM gloops: ive got a couple of tonnes of scrap ally, i was going to melt it down, but you know..too busy etc lol
03:23 PM gregcnc: I didn't know metal expired
03:23 PM jymmm: gregcnc: Look for the "best by" date =)
03:24 PM XXCoder: gregcnc: metal doesnt, but certifications do.
03:24 PM gregcnc: exactly, time is most valuable
03:24 PM methods_: the cert might for certain grades of alum
03:24 PM methods_: especially if it's like T0 or something like that
03:24 PM methods_: 6061-T0
03:24 PM methods_: T1
03:24 PM gregcnc: ah ok, that makes sense
03:25 PM roycroft: i could use some blocks of aluminium
03:25 PM roycroft: please to send some my way, thank you very much
03:25 PM jymmm: WTH, are we playing metal bingo here or what?
03:25 PM roycroft: i won't even charge you storage fees
03:25 PM XXCoder: roy lol
03:25 PM roycroft: and i won't complain that they're past their expiry date
03:26 PM jymmm: roycroft: yes you will, dont lie
03:26 PM roycroft: no, i won't
03:26 PM roycroft: i'm even willing to put that in writing
03:26 PM jymmm: roycroft: :But but but , this hunk isn't purpole enough, blah blah blah
03:26 PM gregcnc: i should have a motor showing up today NIB, ABB 3kW for $182.
03:26 PM jymmm: purple*
03:26 PM gloops: theres no time involved in collecting scrap here, people put it outside to be collected
03:27 PM gloops: unfortunately i havent found any pewter or tin yet outside someones gate
03:27 PM roycroft: after your economy crashes at the end of the month people will be grinding up their cans and making aluminium soup to fill their bellies
03:28 PM methods_: https://en.wikipedia.org/wiki/Precipitation_hardening#Examples_of_precipitation_hardening_materials
03:28 PM gloops: lol! thanks for the words of encouragement roycroft
03:28 PM roycroft: i'm sorry
03:28 PM methods_: the metals in that list would probably have time restrictions on their certs
03:28 PM roycroft: this is what i've been saying for two years
03:28 PM roycroft: and even your prime minister admits this is one of the biggest clusterfucks in british history
03:29 PM gloops: roycroft everyone seems determined our economy is going to crash - its the fastest growing europe
03:29 PM gloops: new employment figures today, best since 1975, we're doing better than fine
03:29 PM methods_: isn't everyone doing fine, until they are not
03:30 PM gloops: us brits will always be ok, its in our genes ;)
03:30 PM gloops: https://www.bbc.co.uk/news/business-47622415
03:30 PM SpeedEvil: https://www.theguardian.com/business/2017/jun/08/uk-economy-falls-to-bottom-of-eu-growth-league
03:31 PM SpeedEvil: Doing great.
03:31 PM XXCoder: yeah stiff upper lip helps
03:31 PM gloops: fake news Speedevil
03:31 PM jymmm: SpeedEvil: ""This article is over 1 year old""
03:32 PM XXCoder: 2017 june
03:32 PM XXCoder: gloops: outdated is not fake news.
03:33 PM gloops: its the Guardian though, EU rag
03:33 PM gloops: anyway, im not going to be drawn into a bexit debate lol
03:34 PM XXCoder: ah ok
03:35 PM syyl: i never realised that the house of commons is like a monty python sketch :D
03:35 PM jymmm: lmao
03:36 PM jymmm: syyl: Where do you think the idea of monty python came from?
03:36 PM syyl: well ;)
03:36 PM syyl: now its obvious
03:36 PM SpeedEvil: syyl: problem is this year it's evolved into the 'not dead yet' knight, rather than the ministry of silly walks.
03:36 PM syyl: but i adore john bercow for his english
03:36 PM rmu: *lol
03:37 PM rmu: *
03:39 PM gloops: dont be deceived by that performance syyl, underneath this is a highly organised country, our govmt works like a finely tuned piano
03:39 PM syyl: sure
03:39 PM syyl: like a british car?
03:39 PM gloops: theres nothing wrong with british cars
03:39 PM syyl: i didnt want to imply that
03:39 PM syyl: :)
03:42 PM gloops: funny how it works, now its the german car industry that looks pretty old and outmoded and yesteryear
03:44 PM syyl: it needs to die.
03:44 PM syyl: die to be reborn
03:45 PM gloops: lol
03:45 PM syyl: i have no love for german cars anyway
03:45 PM syyl: none.
03:45 PM gloops: you are german though?
03:46 PM syyl: yes
03:46 PM gloops: surely there must be some lingering patriotic spirit
03:46 PM syyl: but i smell bullshit 100m against the wind.
03:46 PM syyl: and all the premium blabla is exactly that.
03:46 PM syyl: bullshit
03:46 PM gloops: you must look at an old VW and fell some affinity for that authentic beetle steel
03:47 PM syyl: yes
03:47 PM syyl: that was proper purposedriven engineering
03:47 PM gloops: built by your forefathers
03:47 PM gloops: in your country, with your materials
03:47 PM syyl: just like a french 2cv
03:47 PM syyl: purposedriven, simplistic design
03:48 PM gloops: well yeah, id take the beetle any day though lol
03:50 PM XXCoder: man
03:51 PM XXCoder: just read about some lady who almost died by injecting fruit juice in body
03:51 PM XXCoder: natural food nutters.
03:51 PM gregcnc: people inject heroin, why not?
03:51 PM SpeedEvil: Many people do it with coca extract
03:52 PM XXCoder: heroin is made to be injected
03:52 PM SpeedEvil: With a rigorous quality control procedure.
03:52 PM XXCoder: even shitty qa its still safer lol
03:53 PM gregcnc: I do wonder how humanity survived before ~1900.
03:53 PM XXCoder: easy enough they died. but had enough kids to keep going.
03:54 PM XXCoder: wonder why baby boomer era happened? its because death rate dropped but kid production stayed up but finally dropped. that gap is baby boomer era.
03:55 PM gloops: there were plenty of psychadelic substances thousands of years ago
03:56 PM gloops: or substances used to cause 'highs' or hallucinations etc
03:56 PM XXCoder: always.
03:57 PM gloops: fly agaric mushrooms here
04:57 PM roycroft: xxcoder: part of the baby boomer phenomenon is that people weren't making many babies during the war, and they made up for lost time right after the war
04:59 PM roycroft: i agree that the decrease of the infant mortality rate was a signficant contributor
05:00 PM Deejay: gn8
05:41 PM Tom_L: gregcnc, not sure where you are but you might try these guys for aluminum: http://www.aluminumyard.com/
05:41 PM Tom_L: i get my scrap there all the time
05:42 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/local_stock/stock_index.php
05:47 PM Tom_L: some of their 'smaller' round http://tom-itx.no-ip.biz:81/~webpage/cnc/local_stock/9.jpg
05:47 PM Tom_L: :)
05:55 PM skunkworks: Hmm - A 4k 17" display on a laptop may be the limit of my eyesight...
06:01 PM skunkworks: http://electronicsam.com/images/KandT/testing/primus/Screenshot_2019-03-19_17-53-31.png
06:05 PM skunkworks: andypugh: !
06:05 PM andypugh: Hai
06:06 PM Tom_L: evening
06:06 PM skunkworks: The vm on the screen is 1080...
06:06 PM andypugh: I made a sort of table for my hand-held bandsaw. It’s great!
06:06 PM andypugh: https://photos.app.goo.gl/DJMmPJAF7dE6VAWt9
06:07 PM Tom_L: bolt on table
06:08 PM andypugh: Mounts to the same screw as the stop-plate thing that is used in the hand-held mode
06:08 PM Tom_L: should be ok until you try to run a bar thru the spindle
06:08 PM andypugh: I have since moved it to the fly-press base
06:09 PM Tom_L: i'm gonna try to run that 2.8 ssd this evening and will report the results
06:09 PM Tom_L: just got in
06:09 PM andypugh: I have another mount for the lathe (for cuting off bar-stock in the chuck that is too big to part)
06:10 PM andypugh: I am really impressed with the tool, it wasn’t expensive: https://www.aldi.co.uk/workzone-240v-portable-bandsaw/p/086075229503400
06:12 PM Tom_L: heh not used to seeing Aldi sell tools here
06:12 PM Tom_L: just groceries
06:12 PM Tom_L: what's the blade diameter?
06:12 PM Tom_L: i might have to try and find a place for one here
06:15 PM _unreal_: few new photos https://photos.google.com/share/AF1QipNjUL9VJW4BIh58ZOHM6jOWS10l43lfzL_nr7FMD-YXm_o6hG63BfTN2Rv6ch6C_Q?key=OVV0UTBXUmF0NXNSR2NKVzdoaFhxQzVTbDI5V3JB
06:15 PM _unreal_: kills me but I'm currently putting together my motor controller for a difference cnc machine
06:16 PM _unreal_: I just got 2 nice enclosure boxes that are to perfect for the project
06:16 PM _unreal_: so I'm finally throwing all of the parts intro the box.....
06:16 PM _unreal_: only have a few more parts to solve and connect and I " could " test a motor
06:30 PM skunkworks: OMG finally - my perfect laptop... (other than heavy...)
06:31 PM skunkworks: http://electronicsam.com/images/greenmachine/20190319_182509.jpg
06:31 PM andypugh: Tom_L: Blade diameter? Do you mean width?
06:32 PM Tom_L: no, overall circumference
06:32 PM Tom_L: or cutting area
06:32 PM Tom_L: just judging what size it is
06:32 PM andypugh: It uses this size https://www.ebay.co.uk/itm/Milwaukee-48390531-Pack-of-3-1140mm-24TPI-Portable-Bandsaw-Blades/232431697754
06:33 PM andypugh: It’s fairly small, as you would expect from a handheld saw
06:34 PM Tom_L: yeah, that's about what i expected
06:43 PM infornography: ello
06:44 PM infornography: Anyone willing to help me through sone audio issues?
06:45 PM infornography: maybe audio anyway, I'm trying to get the linuxcnc box to play mp3s, but it sounds funky
06:47 PM a-u: You've not said if the music was funk, and should sound funky....
06:47 PM a-u: or if you happen to have an old PC with slower processor and maybe fewer cores.
06:48 PM a-u: I've used old PCs that seem quite busy keeping track of the RT real time tasks used by LinuxCNC that it is very slow to respond to things...
06:49 PM a-u: ... that others say you may not want to do on a RT-machine - like web pages and such.
06:49 PM infornography: cpu usage "looks" low.
06:50 PM skunkworks: 4k linuxcnc? http://electronicsam.com/images/KandT/testing/primus/Screenshot_2019-03-19_18-46-25.png
06:51 PM a-u: OK - 4K LCNC is cute.
06:53 PM a-u: For the audio issues... did you ever use that platform for a non RTAI kernel? Boot from a live CD (USB) with some other OS and see if it the audio works well?
06:53 PM a-u: There could be kernel / hardware / driver challanges that keep your audio from working well.
06:55 PM infornography: oooo thats a good plan
06:56 PM infornography: Its been running about a year but I didn't try audio until recently
06:56 PM infornography: one of these motherboards
06:56 PM infornography: https://www.amazon.com/ASRock-Motherboard-Mini-DDR3-Q1900B-ITX/dp/B00J2CCCJE
06:57 PM infornography: I'll try a different distro live cd
07:04 PM a-u: We've always used leftover PCs, including far older and lower specs than that mini-board and know we had it playing MP3 tunes under Ubuntu.
07:10 PM infornography: audio worked fine from a live cd
07:10 PM infornography: Does linuxcnc work as a live cd?
07:12 PM a-u: Yep - the distribution image for LCNC boots Debian, I believe.
07:17 PM skunkworks: andypugh: fusion running through a vm in debian... http://electronicsam.com/images/greenmachine/20190319_182509.jpg
07:17 PM andypugh: I had seen that, but not twigged the VM part.
07:17 PM andypugh: (I use a Mac and Fusion Native)
07:24 PM skunkworks: I don't understand why they don't have a linux port..\
07:24 PM skunkworks: the only reason why I keep a windows license...
07:26 PM fdarling: pcw_home: I have some more PID questions for you, I am tuning the velocity mode Yaskawa servos and I ended up needing FF1 values of 30 and 90 and such for the different motors, that seems way off from the theoretical 1.0... I might be scaling things incorrectly
07:26 PM Tom_L: andypugh, running 2.8 i get this: http://tom-itx.no-ip.biz:81/~webpage/screenshots/screen1.png
07:26 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/screenshots/Screen2.png
07:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/screenshots/Screen3.png
07:27 PM Tom_L: just finished running that program on 2.7
07:28 PM fdarling: Tom_L: I think it's trying to interpret the () comment as a function call with nothing preceding it maybe?
07:28 PM Tom_L: i think it's the line numbers
07:28 PM Tom_L: the () are comments
07:28 PM fdarling: Tom_L: what happens if you remove line 2 with the () comment? does it move the problem by more than 1 line?
07:28 PM Tom_L: or always have been
07:29 PM Tom_L: i'll have to go back out and try that
07:29 PM andypugh: Is G28 valid with a Z number?
07:31 PM andypugh: Hmm, sees to be
07:34 PM Tom_L: yes
07:34 PM Tom_L: i ran that program on 2.7 a couple days ago
07:34 PM Tom_L: removing the comment line made no difference
07:34 PM Tom_L: removing some N numbers made no difference
07:34 PM Tom_L: i'll go out and grab the configs and post them (the converted ones)
07:36 PM fdarling: Tom_L: is it possible renaming the extension from .txt to .ngc will fix it?
07:36 PM _unreal_: almost done soldering together my step/dir converter circuit
07:36 PM _unreal_: http://moriscanet.blogspot.com/2009/02/
07:36 PM fdarling: Tom_L: I doubt that will make a difference, but that was the first thing I noticed
07:37 PM _unreal_: 12C508A
07:37 PM _unreal_: I have a bunch of those chips
07:37 PM _unreal_: so finally making the adapter
07:37 PM _unreal_: god I started this project THIS project 15 years ago... and my parts have been sitting idle
07:37 PM _unreal_: NO MORE gall damnnn it
07:40 PM fdarling: Tom_L: here is the line of code responsible for the popup you're seeing: https://github.com/LinuxCNC/linuxcnc/blob/master/src/emc/usr_intf/axis/scripts/axis.py#L1227
07:40 PM Tom_L: fdarling i have that defined in the config
07:40 PM Tom_L: .txt extensions
07:41 PM fdarling: Tom_L: you could get Python to cough up a backtrace and maybe get a clue as to what's going on
07:42 PM andypugh: Something wrong with the graphical preview
07:42 PM fdarling: Tom_L: you might want to do the "massive printf" method of debugging that, simply edit axis.py and put a bunch of print statements showing what it's processing, and what gets spit out last before it gives up
07:42 PM andypugh: It’s something in “load_preview”
07:42 PM Tom_L: this is on wheezy
07:42 PM andypugh: result, seq = o.load_preview(f, canon, initcodes, interpname)
07:43 PM andypugh: But, sadly, I can’t help as I need to sleep.
07:50 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_2.7/
07:50 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_2.8/
07:50 PM Tom_L: there's the 2 sets of configs
07:50 PM Tom_L: i'm running 2.7 on a separate ssd
07:50 PM Tom_L: did the upgrade and ran the config tool
07:51 PM Tom_L: installed 2.7 on another ssd and tested it then did the upgrade to 2.9
07:51 PM Tom_L: 8*
07:54 PM Tom_L: i'll look into it further later on
07:54 PM Tom_L: at least now i've got backups on the server :)
07:55 PM fdarling: Tom_L: the file that is giving you trouble, does it work on other machines?
07:55 PM Tom_L: the file works on 2.7
07:55 PM Tom_L: same pc
07:56 PM Tom_L: i just wanted to test 2.8 out a bit. wasn't really planning to commit to it yet
08:05 PM infornography: linuxcnc live cd doesnt playback audio correctly either
08:15 PM pink_vampire: skunkworks: I like the 4K LCNC
08:15 PM pink_vampire: we need to render the chips that fly from the cut
08:20 PM skunkworks: heh
08:21 PM skunkworks: with ray-tracing
08:43 PM * jymmm sends chips flying at pink_vampire, but no dip for you!!!
08:52 PM pink_vampire: jymmm: what do you mean?
08:53 PM jymmm: pink_vampire: (potato chips)
08:53 PM pink_vampire: loolllllllllllll
08:54 PM roycroft: so does anyone do any threading with a form tool?
08:54 PM roycroft: i suppose that's what cutting an acme thread is
08:55 PM roycroft: but i'm thinking of a round thread
08:55 PM fdarling: roycroft: on a lathe or on a mill?
08:55 PM roycroft: on a lathe
08:56 PM roycroft: i'm wondering how likely i am to fail :)
08:56 PM fdarling: fdarling: I think the hart part is learning how to operate thread cutting mode on the lathe, not so much the shape of the tool. The shape of the tool of course definitely matters for producing usable threads
08:57 PM fdarling: roycroft: I don't know why I addressed that to myself :-P
08:57 PM roycroft: i am reasonably adept at cutting threads with a single point tool
08:57 PM fdarling: roycroft: I've used round form tools to create ball detent rings on cylinders
08:57 PM roycroft: here's the thing
08:57 PM roycroft: i need to make some torsion springs
08:57 PM roycroft: i've tried winding the music wire around a cylinder
08:58 PM fdarling: roycroft: this is already sounding dangerous
08:58 PM roycroft: i have a really hard time keeping the windings even
08:58 PM roycroft: i thought that if i made a round form tool that is the diameter of the music wire i could make a mandrel to wrap the music wire around
08:58 PM roycroft: and i'd get a more even wind
08:59 PM roycroft: it's potentially dangerous
08:59 PM fdarling: roycroft: maybe a 3D printed one would hold up to the compressive forces?
08:59 PM roycroft: i don't think a 3d printed one would work
08:59 PM fdarling: roycroft: why not?
08:59 PM roycroft: but i don't have a 3d printer, so that's irrelevant
08:59 PM roycroft: i think i would crush the 3d mandrel
09:00 PM fdarling: roycroft: it would be a sleeve to go over a metal cylinder
09:00 PM roycroft: this wire is about 0.210"/5.4mm in diameter
09:00 PM fdarling: roycroft: print it out of PETG with 100% infill and I'll bet it would hold up
09:00 PM roycroft: but again
09:00 PM roycroft: i have no 3d printer
09:00 PM roycroft: but i do have a lathe
09:01 PM fdarling: roycroft: all right, well I think the lathe would do fine, just take light cuts and make the mandrel out of aluminum or something if you're worried about the forming tool
09:01 PM fdarling: roycroft: you don't even have a friend with a 3D printer?
09:01 PM roycroft: i've made rounded form tools in the past
09:01 PM roycroft: and i've used them with reasonable success
09:01 PM roycroft: but i always plunge them straight into the work
09:01 PM roycroft: i've never attempted a thread pattern with one
09:02 PM roycroft: but yes, really light cuts would be in order
09:02 PM roycroft: unfortunately, my lathe only goes down to 80rpm
09:02 PM roycroft: and it would be a fairly rough thread pitch, since the thread would be 0.210" wide and cannot overlap
09:03 PM roycroft: so approximately 5 tpi
09:03 PM roycroft: probably 4tpi to be safe
09:03 PM roycroft: i don't have the gearing to do 4.75tpi on my lathe
09:03 PM roycroft: but don't worry - i have a jig to make the springs safely
09:04 PM roycroft: i just need something better than a cylinder to wrap the wire around
09:22 PM roycroft: my main concern about this project is the geometry of the tooling - i need to be sure to have enough relief
09:54 PM skunkworks: Fixed a ribbon cable (one of the plastic strips with copper applied to it)
09:54 PM skunkworks: Whoever worked on it ripped the copper off the end. Cut it short and gently scraped the insulation off to expose the copper..
09:55 PM skunkworks: worked sprisingly..
09:55 PM skunkworks: this was about 1/8 inch wide cable with about 6 conductors..
09:56 PM skunkworks: (ran power, hd and battery led's on a laptop)
10:07 PM a-u: I've wound a variety of coils on a round mandrel powered by good cordless drivers, often with a crude jig to space one turn to the next - but you may be working with a lower gauge wire....
10:13 PM skunkworks: like https://www.youtube.com/watch?v=hUR-43Lrfos
10:13 PM skunkworks: ?
10:13 PM skunkworks: ;) That goes in a wrist watch....
10:14 PM roycroft: were you talking to me, a-u?
10:17 PM a-u: roycroft: yes
10:17 PM roycroft: this wire is pretty stiff
10:17 PM roycroft: as in i have to huff and puff to bend it manually
10:17 PM roycroft: it's 0.210"/5.33mm in diameter
10:18 PM roycroft: but the issue is not bending it
10:18 PM roycroft: it's making the coil neat and tidy
10:18 PM a-u: oops - no, I was working 16 - 14 gauge. You would need an industrial jig
10:18 PM roycroft: i made a jig
10:18 PM roycroft: but when i bend it around a cylinder the coil doesn't "nest" very well
10:19 PM roycroft: that's why i thought that turning a round thread on the cylinder might help
10:19 PM roycroft: and you know, a v-groove thread would probably work fine
10:19 PM roycroft: i may be making this more difficult than it needs to be
10:20 PM roycroft: i've made a couple that are functional ,but they are ugly
10:20 PM roycroft: and i don't like making ugly stuff
10:21 PM a-u: I suspect the issue is precision force and track - that the modulus you are trying to change is so high that small variations cause visible changes
10:22 PM a-u: I suspect an old school machinist would say bend first, then harden / temper.
10:22 PM roycroft: i'm kind of intrigued by the idea of making a form tool to cut a rounded thread
10:22 PM roycroft: i might give it a go just to see if i can make it work decently
10:24 PM roycroft: it might be best to form most of the thread with a v-groove tool, then finish it with the round tool
10:24 PM a-u: So grind carbide to a rounded shape to thread with?
10:24 PM roycroft: i'll use hss
10:24 PM roycroft: but yes, i'll make the tool
10:25 PM roycroft: i'm concerned primarily with making sure i have sufficient clearance
10:25 PM roycroft: and somewhat concerned about chatter
10:26 PM roycroft: and slightly concerned with cutting a very coarse pitch thread with a lathe that i can't run as slowly as i'd like
10:26 PM a-u: Seems possible. I remember someone selling jig and dies for cutting Acme thread.
10:26 PM roycroft: i've cut acme threads on the lathe
10:26 PM roycroft: it's been a long time though
10:26 PM a-u: I cheated and bought ballscrew and nuts direct from China.
10:27 PM a-u: And rails and linear bearings.
10:28 PM Tom_L: roycroft, i had my friend cut a 3 tpi thread for me on his lathe once
10:28 PM Tom_L: that was rather interesting
10:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/thread1.jpg
10:30 PM Tom_L: you just can't go as slow as you'd like
10:32 PM a-u: I've never tried anything in that range other than via cnc A axis
10:32 PM Tom_L: he'd never used that gear on his lathe
10:32 PM Tom_L: but he had it :)
10:32 PM a-u: Nice
10:32 PM Tom_L: most lathes won't go that coarse
10:32 PM Tom_L: most stop around 8
10:33 PM roycroft: i just checked
10:33 PM roycroft: i can cut 4.5tpi, which is really close to what i need
10:34 PM roycroft: and my low speed is 60rpm, not 80rpm
10:34 PM _unreal_: There finished building the stupid step/dir to phase adapter board
10:34 PM roycroft: i'd prefer more like 40rpm or even 25rpm for this
10:34 PM Tom_L: still seems fast when you're feeding that quick
10:34 PM roycroft: it does
10:34 PM roycroft: and i'm an old fart
10:34 PM Tom_L: and you gotta hit your mark to engage the drive just right..
10:34 PM roycroft: my reaction time is not what it used to be
10:35 PM Tom_L: :)
10:35 PM roycroft: i might not disengate
10:35 PM roycroft: disengage
10:35 PM Tom_L: he did and made i think either 3 or 4 passes
10:35 PM roycroft: just leave the half nut engaged, back the tool off, and back up
10:35 PM roycroft: then repeate
10:36 PM roycroft: since i'll be using a round tool i'll need to make very very light cuts
10:36 PM roycroft: i can see a dozen or more passes easily
10:36 PM Tom_L: yeah
10:37 PM roycroft: 4.76tpi is what i need to lay the coils right next to each other
10:37 PM roycroft: 4.5tpi is close enough to that i think
10:37 PM roycroft: 5tpi would be crowding it
10:37 PM _unreal_: roycroft, Thats a quarter of a turn difference
10:37 PM Tom_L: depends how many rows of coil
10:37 PM _unreal_: doesnt take many rotations to add up
10:38 PM roycroft: i only need a bit over an inch
10:38 PM roycroft: so 5 coils or so
10:38 PM Tom_L: if that's true every 5th one would skip over the cut
10:38 PM roycroft: yes, that's why making it a bit coarser is better than a bit finer
10:41 PM * Tom_L blows out the candle and goes to sleep
10:41 PM roycroft: this would be a good time to swap my lathe motor for a 3 phase one with a vfd
10:41 PM roycroft: no more belt changing
10:41 PM roycroft: and a wider speed range
10:43 PM a-u: How much power do you need on your lathe
10:43 PM roycroft: it has a 2hp motor
10:43 PM roycroft: and i would replace it with another 2hp motor
10:43 PM roycroft: it's a 12x36
10:44 PM roycroft: that's a nice size, and the motor power is well matched to it
10:46 PM a-u: Yes - VFD are not that expensive and the control is nice.
10:46 PM roycroft: the lathe is belt drive
10:46 PM roycroft: i like how quiet it is and how smoothly it runs
10:46 PM roycroft: but i do not like moving the belt around to change speeds
10:47 PM a-u: Yes, the VFD motors won't make the same noise as a 3600 RPM or similar synchronous AC motor.
10:48 PM roycroft: i'm building a belt grinder, and i originally bought a 2hp motor for it
10:48 PM roycroft: i got a 2.2kw vfd for that, because i'm feeding it single phase, and like to oversize the vfd a bit when doing that
10:48 PM roycroft: especially an asian import vfd
10:49 PM roycroft: i just decided to use a 3hp motor for the belt grinder
10:49 PM roycroft: i was going to start out with the 2.2kw vfd, but i might get the next size up instead
10:49 PM roycroft: and repurpose the 2.2kw for my lathe
10:50 PM roycroft: if i want to run the lathe at 25rpm, though, i'll definitely need an inverter rated motor
10:53 PM a-u: We're only using VFD on spindle. Guessing you may still have some belt reduction, but not much spindle power below about 300 RPM
10:53 PM roycroft: yeah, i have belt reduction
10:54 PM roycroft: and i have a low and a high speed range
10:54 PM roycroft: i'll probably continue to swap that belt around
10:54 PM roycroft: right now my speed range is 60-1600rpm, iirc
10:54 PM roycroft: i know 60 is the low end
10:54 PM roycroft: and i'm pretty sure that 1600 is the high speed
11:07 PM roycroft: 1240 is the highest speed
11:21 PM fdarling: does anyone know if a PCI WiFi card adversely affects latency on LinuxCNC? I've read that onboard WiFi can cause issues sometimes
11:23 PM a-u: My understanding is always limited, but what I've gathered -- yes, many "extra" network, wifi, graphics, sound, etc. interfaces could all effect the RT aspects needed for LinuxCNC
11:24 PM a-u: With some of the now kinda ancient PC hardware, things clearly had an impact.
11:25 PM fdarling: if budget isn't an issue, what is a recommended LinuxCNC setup with low latency? I am shooting for a 4kHz servo thread (Mesa cards not software stepping)
11:25 PM a-u: Now... it seems not so much -- as some of us risky types have run firefox and played MP3s while leaving network / wifi running while running long LCNC jobs.
11:26 PM a-u: I've been using DC servo motors with external drivers and never touched a Mesa card... so maybe my experience is not a help.
11:26 PM a-u: We are using a circa 2012 Dell PC and have base set to 20,000 ns.
11:27 PM fdarling: a-u: what are you using to interface to the DC servos?
11:30 PM a-u: Geckodrive
11:30 PM fdarling: a-u: so you are using a step/dir interfaced drive then
11:30 PM a-u: Yes
11:33 PM a-u: I think max production step rate is about 27000/sec
11:35 PM a-u: We have a RTAI error on launch... and while I don't have any hard info, it seems to be a launch fluke, as I can't find other signs that RTAI gets delayed.
11:37 PM a-u: But - kinda back to your question - the current PC has 5 or 7 cores so ideally the RT preempt all runs seamlessly and the other cores pick up graphics or network or other loads when the other cores and memory, etc. can get to them
11:39 PM fdarling: a-u: you are using RTAI and not the uspace one?
