02:25 AM MrHindsight is now known as CaptHindsight
02:27 AM Deejay: moin
02:35 AM Jymmm: Monring Deejay
04:41 AM Loetmichel: *AUAUAUAUAUAUA* just losened an allen screw... with the finger that had the scalpel cut tuesday. had to use FORCE... finally the screw broke lose, and the allen key HAMMERS exactly on the still slightly inflamed cut. I am not very whiney, but THAT was "inconvenient" to say the least... coworkers learned a few new cusswords. ;)
04:48 AM p0g0_: Loetmichel, can we offer to teach you to cuss in some foreign language, to not offend your co-workers? I guess English is a non-starter tho, so maybe Spanish or French?
04:49 AM XXCoder: nahh
04:49 AM XXCoder: oh dammit
04:49 AM XXCoder: nm
04:49 AM Loetmichel: p0g0_: wouldnt work
04:50 AM p0g0_: 'k
04:50 AM Loetmichel: we have russians, pakistani, polish, chinese and romanian workers
04:50 AM Loetmichel: i guess there are PLENTY of language understood here
04:50 AM XXCoder: just use random noises?
04:50 AM Loetmichel: +s
04:50 AM p0g0_: mmm, that is a challenge then- Latin, Qwlmian (sp) or Welsh then.
04:51 AM Loetmichel: and can already cuss in all those languages ;)
05:00 AM Tom_L: morning
05:11 AM Tom_L: 13°F
05:11 AM XXCoder: man you guys have so varied temperate experence lol
05:12 AM Tom_L: yessir
05:22 AM Loetmichel: Tom_L: sounds a bit cold. is the breath freezing in midair already?
05:23 AM XXCoder: 13f should be well within "fake smoking" range
05:23 AM jthornton: morning
05:23 AM XXCoder: yo
05:24 AM Loetmichel: XXCoder: not smoking. FREEZING breath. thats different ;)
05:24 AM Loetmichel: i mean: not fog
05:24 AM XXCoder: 17f hmm not too sure if thats cold enough for that
05:24 AM Loetmichel: but instant "snow"
05:24 AM XXCoder: no, that needs negative temperates
05:25 AM XXCoder: 50f/c is when you can throw boiling water and it turns into snow
05:25 AM XXCoder: erm 40
05:25 AM XXCoder: breath like that not too sure
05:25 AM Loetmichel: -40 you mean?
05:25 AM XXCoder: yeah sorry
05:27 AM Loetmichel: ah, 15F is just -10C. thats still Tshirt weather.
05:28 AM p0g0_: Much of the US enjoys a "continetal climate" it is typical of large land masses to change T more than the ocean bounded folks.
05:29 AM p0g0_: *Continental
05:29 AM XXCoder: yeah usa-wise im just spitting distance to ocean
05:33 AM jthornton: 37°F, high today 34°F then falling to a low of 16°F
05:34 AM XXCoder: today it will be 43f to 39f
05:35 AM XXCoder: 4 whole degrees whoa
05:35 AM XXCoder: in fall I had 50f allll day. no change at all
05:36 AM * Loetmichel had to scrape the car windows this morning... so probably -2 to -5°C here
05:36 AM Loetmichel: now its a cozy +6°C outside
06:35 AM jdh: 73f here today
06:37 AM p0g0_: Florida?
06:37 AM jdh: NC
06:37 AM jdh: on the coast
07:07 AM Loetmichel: soo, next ender3 is printing the test cat... maaan that "throw in" PLA sample is BAD. but it works. Kind of. coworker that assembled it had to file the z motor mount quite a bit though to get it in line with the nut. those injection molded parts are bad for alignment.
08:16 AM fogl81: hello
08:17 AM jdh: my ender3 assembly directions made perfect sense after assembly. zero sense during assembly
08:18 AM jdh: Loetmichel: are yours stock? auto leveling? thermal shutdown? whiney stepper drivers?
08:24 AM fogl81: i am trying to compile my own .comp linuxcnc component. I installed linuxcnc 2.7.15 from git, so i assumed all the tools to make components are already installed, but i connot find the halcompile. sudo apt-get install linuxcnc-dev also doent install anything.
08:24 AM fogl81: were there some changes not noted
08:29 AM JT-Shop: sudo apt install linuxcnc-dev should add the hal component generator in most distros at least it works on debian and linux mint
08:33 AM fogl81: This command return "unable to locate package". Where is this package?
08:34 AM JT-Shop: hmm, I'm trying to remember but you need an extra repository added
08:35 AM JT-Shop: linuxcnc-uspace-dev on this one I think... checking
08:35 AM jymmmm: Good morning
08:36 AM fogl81: But it is still not completely clear to me (i am not a specialist though) if i installed from source/git, those packages should be on my system already?
08:38 AM JT-Shop: no, it's in a separate repository IIRC
08:38 AM JT-Shop: I'm not having any luck here on debian 9 either
08:38 AM * JT-Shop has to tend to the chickens for a bit bbl
08:42 AM unterhaus: I have some barely used Starrett test indicators that are locked up solid
08:44 AM JT-Shop: fogl81, anyone reading back would need to know the OS your using
08:46 AM fogl81: linux mint 4.19.1-rt3
08:47 AM Javabean: linux mint: debian edition?
08:47 AM unterhaus: I don't see references to different repositories after a quick glance at linuxcnc.org
08:49 AM fogl81: Linux Minte 19.1 Tessa
08:50 AM unterhaus: is it halcompile.g?
08:51 AM fogl81: no, there is no halcompile.g on my system
08:51 AM fogl81: i installed the system following the instructions here https://gnipsel.com/linuxcnc/uspace/linuxmint19-rt.html
08:56 AM unterhaus: I was just looking in the git
08:57 AM unterhaus: "This is 'halcompile', a tool to write HAL boilerplate"
08:58 AM unterhaus: oh, looking for "comp"
09:03 AM unterhaus: "To compile a component you need to install dev."
09:06 AM veegee: Any recommendations for a rotary table?
09:06 AM Loetmichel: jdh: totally stock
09:06 AM veegee: I bought the vertex 6" one, but I'm going to exchange it for a 12" one. I want a nice one
09:06 AM Loetmichel: just the cams as additions
09:08 AM CaptHindsight: veegee: these are nice https://www.haascnc.com/machines/rotaries-indexers/rotary-tables.html
09:08 AM Loetmichel: and recently i printed a few fan hoods for the PSU and mainboard fans because one is loud and the other is proe to eat filament debris and get blocked
09:09 AM veegee: CaptHindsight FUCK ME SIDEWAYS starting at $10,000!?
09:09 AM veegee: I was hoping more in the $1,000-$2,000 range
09:09 AM fogl81: @unterhaus: how can i install the dev
09:09 AM veegee: It doesn't need to be CNC, I just want a fully manual one
09:10 AM CaptHindsight: veegee: I come across really nice used ones all the time
09:10 AM CaptHindsight: veegee: do you need new?
09:11 AM veegee: Nope, doesn't need to be new, can be used
09:11 AM veegee: as long as it holds its tolerance
09:14 AM CaptHindsight: #800 new https://www.grizzly.com/products/Grizzly-12-Horizontal-Vertical-Rotary-Table-Yuasa-Type/G9300
09:14 AM CaptHindsight: $800
09:15 AM jthornton: I have one of those... IIRC it's 12"
09:16 AM unterhaus: I really want a Moore. Tried to talk someone into giving me one, no joy
09:16 AM veegee: CaptHindsight I have a Vertex https://www.amazon.ca/gp/product/B00V2YTKKO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
09:16 AM unterhaus: Moore rotary table is the only vernier I am happy to use
09:16 AM CaptHindsight: Chinese versions https://www.shars.com/products/workholding/rotary-machining-tables
09:16 AM veegee: Is the Yuasa better than the Vertex ?
09:17 AM unterhaus: andypugh has built cnc indexers
09:17 AM unterhaus: fog181 there should be a dev package for the version of linuxcnc you are using
09:19 AM CaptHindsight: https://www.ebay.com/itm/VERTEX-12-Horizontal-Vertical-Rotary-Table-Center-Hole-4MT/283621262797
09:19 AM CaptHindsight: https://www.ebay.com/itm/NIB-PYH-12-Horizontal-Vertical-ROTARY-TABLE/233477889149
09:20 AM unterhaus: moore rotary tables on ebay go for between 800 and 8000. the 8000 one looks really nice
09:33 AM fogl81: @unterhaus: i think so also, i also think it should be on my sisysem somewhere if i installed it from git. But i cannot find it, on my system and also not somewhere else - any help would be very much appriciated
09:45 AM unterhaus: I'm pretty sure that if you installed from source, then there is no dev package. but maybe I misunderstand what you mean "from git" maybe a build option?
09:53 AM unterhaus: when I say "no devl package" I mean it's there and you might have a path issue
10:01 AM JT-Shop: https://imagebin.ca/v/5CCrJsU7QbRs
11:40 AM Loetmichel: maaan, the BMW needs a new clutch soon. just gave it a bit much throttle at the traffic light on the way home. Let the clutch pedal go: engine revs 3k... and stays there for 5 seconds while the car accelerates in first gear to match that rpm... seeems its slipping a "wee bit" ;)
12:18 PM skunkworks: http://electronicsam.com/images/greenmachine/2020-02-13-120025_1920x1080_scrot.png
12:21 PM Tom_L: can you imagine an rpi4 running something like the cincinati at MPM....
12:22 PM skunkworks: probably not...
12:22 PM skunkworks: maybe..
12:22 PM Tom_L: :)
12:24 PM skunkworks: 53c
12:24 PM skunkworks: It might be able to run a 40us base thread
12:25 PM Tom_L: it's not like it runs 400+ ipm thru aluminum
12:25 PM skunkworks: that would (if reset was programmed into the gpio driver) give you a max of 25khz.. Good for lots of thigns
12:26 PM skunkworks: Tom_L: Oh - I think it could do it - but the it would have to run ethrenet or spi based hardware..
12:26 PM Tom_L: right
12:26 PM Tom_L: did jepler fix the spi?
12:26 PM skunkworks: and may have to run a 500hz servo thread. and I don't know how much headroom his kins take.
12:26 PM skunkworks: Tom_L: I think so?
12:28 PM skunkworks: I think it would run the matsuura..
12:29 PM Tom_L: well now you've got another viable project
12:29 PM skunkworks: it would be interesting to see what kind of headroom ladder takes. I remember it having an impact on the old atom processors
12:29 PM skunkworks: Tom_L: but it already has a computer in there... ;0
12:29 PM Tom_L: i'm kinda wondering what sort of impact this new qtpyvcp will have on performance
12:30 PM Tom_L: although that seems to need newer hardware anyway
02:28 PM unterhaus: small ssd prices are a jumble
02:29 PM unterhaus: seems like you can get 500gb for only a few $ more than 256
02:32 PM CaptHindsight: similar to HDD there is a floor
03:04 PM SpeedEvil: It's insane you can get 15T 2.5" SSDs.
03:04 PM SpeedEvil: Admittedly $5K. But still.
03:11 PM CaptHindsight: how many more years until x86 PC on chip with storage?
03:13 PM CaptHindsight: AMD 3990 has 64 cores and 256MB of L3
03:15 PM JesseG: CaptHindsight, thanks for the links earlier! Are you involved in any of those projects?
03:15 PM JesseG: I'm actually thinking of making a ridged mounted balancing setup that users nearly zero-displacement realtime force sensors to measure out of balance
03:16 PM CaptHindsight: I was going to build one to balance spindles
03:17 PM SpeedEvil: CaptHindsight: does ESP32 emulating IBMPC count?
03:17 PM SpeedEvil: (perhaps not quite there yet, but nearly)
03:18 PM CaptHindsight: 256MB is enough space for a linux kernel, file system and some big apps
03:20 PM CaptHindsight: some of the ARM SOC's had POP with system memory, add a big NAND flash and you have it
03:32 PM MrHindsight is now known as CaptHindsight
03:49 PM Deejay: gn8
04:32 PM * JT-Shop should have watched the video on changing the eye phone battery before ordering the battery... need some eye phone screwdrivers and adhesive
04:33 PM _unreal_: ve7it, sweet I got my pic programmer finally
04:36 PM _unreal_: ve7it, you where saying I may have to compile a custom hex?
04:39 PM ve7it: possible... but try the hex file you have
04:40 PM _unreal_: trying to figure out how to use the pickit, didnt come with any software
04:40 PM _unreal_: pickit3
04:41 PM _unreal_: one other question, I have two of the servo controllers "" done "" I just need to add the jumper wires. Do any of those jumper wires carry high current? Or are they just signal wires and I can use simple lite wiring
04:41 PM _unreal_: trying to figure out how to use the pickit, didnt come with any software for my pickit3
04:41 PM _unreal_: 3
04:44 PM _unreal_: ve7it, the servo driver?
04:45 PM _unreal_: do I need heavy guage wire for the jumper wires? or can they all be lite signal wire?
04:52 PM ve7it: dont remember... I think they are all small signal
04:52 PM _unreal_: just starting to install mplab
04:52 PM _unreal_: just finished downloading. I mean Whats a gig
04:52 PM _unreal_: download
04:55 PM _unreal_: arg....
04:55 PM _unreal_: i5 computer and this thing is taking for ever to instsall
04:55 PM elmo40: to install or download?
04:55 PM _unreal_: both
04:56 PM _unreal_: I may as well go take a shower
04:56 PM _unreal_: tonights goal
04:56 PM _unreal_: get my daughters Vday cards etc.... then
04:56 PM elmo40: shower is the goal?
04:57 PM _unreal_: get the last of the wires soldered to the two servo drivers that are ready and get the pics programmed
04:57 PM _unreal_: will be nice to be able to maybe test drive a motor
04:57 PM elmo40: i wanna see your machine purr!
04:57 PM _unreal_: you and me both
04:57 PM _unreal_: I'm waiting on the BIG caps for the psu
04:58 PM _unreal_: so I could use a 24v switching PSU to try driving a single motor
04:58 PM _unreal_: but I'd also have to ? setup an arduino
04:58 PM _unreal_: so I could control the servo controller
04:58 PM _unreal_: POT, a switch and a button
04:59 PM _unreal_: switch for direction, button for "power" and pot for speed control
04:59 PM _unreal_: but I cant test the motor on the machine till I get the belt working
04:59 PM _unreal_: I need to adjust one or two things to get enough slack in the belt so I can set it up
04:59 PM _unreal_: anoying
05:00 PM _unreal_: I only need enough tension on the belts so that it cant slip
05:00 PM _unreal_: belt
05:04 PM _unreal_: ok that just finished installing, I'm taking a shower
05:21 PM _unreal_: back in a while, got to get the holiday stuff for my my daught for her school event :)
05:45 PM unterhaus_: I really want to print a couple of manuals, but it's over 100 pages
05:47 PM unterhaus_: kinkos charges by the page, not by the sheet of paper
06:24 PM unterhaus_: machine learning is so cool, I just bought a 3mm bolt assortment from Amazon and now they are trying to sell me more 3mm bolts
06:24 PM unterhaus_: programmer that made up that algorithm deserves every penny, it's genius
06:25 PM unterhaus_: it's like they were reading my mind
06:26 PM ziper: lol
06:35 PM unterhaus_: I just got shipping notification on the bolts, coming tomorrow instead of monday that they previously promised, so that's good
06:36 PM gregcnc: you need moar M3 fasteners for sure., even if you don't know it yet
06:36 PM jthornton: that's better than my Woodpecker... still waiting on shipping conformation
06:41 PM unterhaus_: I didn't think I ever would need any m3 bolts but I recently realized that I didn't want to deal with 6-32 anymore
06:42 PM unterhaus_: or 4-40, for that matter
06:44 PM unterhaus_: jthornton what woodpecker? They keep making new stuff
06:45 PM gregcnc: the poky thing for rc building or?
06:46 PM unterhaus_: if we are talking about the same woodpecker, I kinda want a saw gauge, but not at $250
06:47 PM gregcnc: oh them, they make all kinds of stuff
06:47 PM unterhaus_: some of their stuff should be made out of hardened stainless instead of red aluminum
06:48 PM gregcnc: if people would pay for it, start making them
06:48 PM unterhaus_: in some cases, the alternative exists. It's just that they have fans that buy thier stuff instead
06:51 PM unterhaus_: the definitely have the world's most expensive speed square, $50
06:53 PM Javabean: having a speedsquare made out of pure silver does sound nice
06:54 PM unterhaus_: the most egregious examples are the one-time tools. Most of their normal catalog is ok
06:54 PM Javabean: most "one-time tools/equiptment" is ridiculusly overpriced
06:55 PM unterhaus_: I guess that's the point of having one-time tools. But they are just copying old stanley tools for the most part
06:56 PM unterhaus_: chamfer plane, but aluminum! Trammel points, but aluminum!
06:57 PM unterhaus_: more power to them, I guess
06:57 PM * Javabean would prefer japanese style planes
06:58 PM CaptHindsight: Mike Judge is working on a new series about a near future where an Amazon like co sends you things before you think you need it....
06:59 PM CaptHindsight: the plot is all about somebody getting something they really don't want and try to return it
06:59 PM unterhaus_: good luck with that
06:59 PM Javabean: considering how expensive the stuff in amazon's emails to me are... that sounds really rather expensive
06:59 PM CaptHindsight: there is no return dept since the AI always predicts with 100% accuracy
07:00 PM unterhaus_: there is a show on netflix like that. Sorta
07:01 PM unterhaus_: one of the episodes of Phillip k. Dick's electric dreams
07:01 PM CaptHindsight: https://www.indiebound.org/book/9781538732960 is the book it is based on
07:01 PM CaptHindsight: Qualityland
07:02 PM unterhaus_: okay, I guess you could make a living rewriting Phillip K. Dick stories
07:03 PM CaptHindsight: which K. Dick story are you referring to?
07:06 PM CaptHindsight: yes one likely can
07:08 PM unterhaus_: "autofac"
07:08 PM unterhaus_: I was wrong it's on amazon
07:08 PM unterhaus_: which is funny
07:10 PM unterhaus_: there is a comedy special on Netflix where the subject of amazon predicting what you want is central to his main story
07:10 PM unterhaus_: but first, he came up with "amazon now" which is where you get something when you decide you want it
07:11 PM unterhaus_: that already exists, except there is a 2 hour delay.
07:14 PM unterhaus_: Ronnie Chieng is the comedian.
07:19 PM unterhaus_: he suggests "Prime before"
07:23 PM t4nk_freenode: Loetmichel, ... "those cheap drills work surprisingly well" ey? :) ... :| I went and bought a decent cocrete drill, thinking I'd be home dry. *sigh* not even an inch deep it went!
07:25 PM t4nk_freenode: I was supposed to drill 9 holes, but I instantly gave up on it, bought a strip of wood and made use of some existing holes in the stones just beneath the ceiling, fixed my curtain rails onto that instead
08:25 PM SpeedEvil: 'concrete' is almost as defined as 'cake'.
08:25 PM SpeedEvil: If you include both pound and yellow.
08:26 PM elmo40: true.
08:26 PM elmo40: it can be a mix of a million diff things.
08:26 PM elmo40: just like plastic!
08:46 PM _unreal_: t4nk_freenode, do you have a hammer drill?
08:46 PM _unreal_: those kind of drills dont work well if your not using a hammer drill
08:47 PM t4nk_freenode: I think the machine is just utter rubbish
08:47 PM _unreal_: ve7it, trying to figure out how to get this code written to the chip
08:47 PM elmo40: any masonry needs a hammer action to it
08:48 PM elmo40: _unreal_, use a battery and binary tap the terminals to the leads...
08:48 PM t4nk_freenode: sure it's a 'hammer drill'
08:48 PM _unreal_: elmo40, just 299,999,999 more bits to tap in
08:49 PM t4nk_freenode: _unreal_, you are a liar :((
08:49 PM t4nk_freenode: your pic don't have that much mem
08:49 PM _unreal_: I might be
08:49 PM elmo40: dont make a mistake (sneeze) and double tap a 1 instead of 0!
08:51 PM _unreal_: elmo40, ever played with pickit3?
08:52 PM elmo40: https://images-na.ssl-images-amazon.com/images/I/61KtLaKNFsL._AC_SL1181_.jpg
08:52 PM elmo40: this?
08:52 PM elmo40: nope
08:52 PM _unreal_: si
08:52 PM t4nk_freenode: zif socket is pretty useless if you're developing
08:52 PM elmo40: i used a jtag thingy once... in highschool! (over 100 years ago when binary was just invented) >_<
08:53 PM _unreal_: I just need to dump ve7it code to this dspic
08:54 PM elmo40: for your mill?
08:55 PM elmo40: https://i.ebayimg.com/images/g/XUUAAOSwke9aTaXf/s-l1600.jpg
08:55 PM elmo40: i have one of these that i never used :-P
08:59 PM _unreal_: hum
09:00 PM _unreal_: @#!@#$ target device was not found
09:00 PM _unreal_: ARG...
09:00 PM t4nk_freenode: fried it? :)
09:00 PM _unreal_: not likely
09:01 PM t4nk_freenode: lol, I know you :b
09:01 PM Javabean: its probably not fried... more likely baked
09:01 PM Javabean: :p
09:02 PM elmo40: have the drivers installed?
09:02 PM elmo40: correct port?
09:09 PM _unreal_: I dont know anything about pickit3
09:48 PM ve7it: _unreal_, the ide should make it easy.... did you get the code to compile? or the ide should have options for uploading to device... it has been 13 years since i worked on that project!
09:49 PM t4nk_freenode: well, if he has 'target device not found', it won't have anything to do with compiling
09:50 PM t4nk_freenode: I don't have a pickit3 btw, just the pickit2 clone I built
09:50 PM t4nk_freenode: and some custom pic-driven usb programmer
09:50 PM ve7it: _unreal_, it would open the ide, make a new project, select the correct processor, add the source to the project, select the programming dongle and see if it will upload
10:01 PM ve7it: _unreal_, using the pickit2 from the command line... pk2cmd -PDSPIC30F4012 -Fdspic-servo.hex there must be something similar for the pickit3
10:04 PM ve7it: _unreal_, this should be downloadable... if not included in ide https://www.youtube.com/watch?v=3EkNUa2nSDE
10:59 PM _unreal_: checking
11:10 PM _unreal_: ve7it, I just found the software on archive.org
11:10 PM _unreal_: isnstalling now
11:24 PM flyback: https://soundcloud.com/wayfu/wayfinder-indestructible
11:24 PM flyback: working music
11:59 PM flyback is now known as fishhead
11:59 PM fishhead is now known as i8086
