12:12 AM Deejay: moin
12:55 AM rtagro: has any one here built cnc plasma cutting, running on linuxcnc?
01:00 AM jym: rtagro: a few have actually, Try JT-Shop tomorrow around 7am pacific time
01:01 AM rtagro: jym, ok thanks
02:50 AM XXCoder: backwards forwards
03:20 AM pink_vampire: hi
03:21 AM XXCoder: hey
03:29 AM pink_vampire: https://i.imgur.com/w0Bk7ms.png
03:29 AM XXCoder: interesting
03:29 AM XXCoder: using sp[indle as rotatary axis?
03:30 AM pink_vampire: correct
03:31 AM XXCoder: nice
03:32 AM pink_vampire: https://i.imgur.com/dRiAkFT.png
03:33 AM pink_vampire: this is the part
03:33 AM XXCoder: interesting design
03:34 AM pink_vampire: hope to make it in 2 setups
03:35 AM pink_vampire: 1 for machining and parting, then just tapping on the top hole
05:17 AM jthornton: morning
05:18 AM XXCoder: hey jt
05:18 AM XXCoder: you remember me talking engraving those super annoying inocel disks?
05:20 AM XXCoder: tools constantly breaking and all
05:21 AM jthornton: aye
05:21 AM XXCoder: well i recently found some very happy news
05:22 AM XXCoder: its now outprocessed, and by laser too lol
05:22 AM XXCoder: i have engraved literal thousands of those. it wont happen again
05:22 AM jthornton: nice
05:23 AM XXCoder: yeah
05:23 AM XXCoder: it'd be better quality also
05:23 AM XXCoder: and no more thickness measuring since .0005 can destroy tool lol
05:24 AM XXCoder: its apperence changes so much with .0005" changes
05:37 AM jthornton: why is is so freekin hard to just find a simple page with the isosceles right-angled triangle formulas
05:38 AM XXCoder: dunno but theres few apps lol
05:39 AM XXCoder: you'd have to look real hard for no ad ones tho lol
05:39 AM jthornton: a million calculators on the net but I need the formula not an app
05:39 AM XXCoder: mine is "tringle solver"
05:39 AM XXCoder: green curcle with tringle in it
05:39 AM XXCoder: yeah annoying. try search trig tringle
05:40 AM XXCoder: http://www.softschools.com/math/calculus/the_6_trig_ratios/
05:40 AM jthornton: I find a bunch of examples that use math symbols but don't break that down
05:40 AM XXCoder: this is all you need for all tringle fun
05:50 AM XXCoder: i'd get an used trig book
05:50 AM XXCoder: probably $5
05:50 AM XXCoder: or free with shipping
05:50 AM XXCoder: info in it is forever
05:50 AM jthornton: I have the machinery handbook out in the machine shop
05:51 AM XXCoder: that should have list of trig identifies also
05:54 AM jthornton: yea it has all the trig stuff, just don't feel like going out there yet
05:54 AM XXCoder: lol
05:54 AM XXCoder: easier to google than walk :)
05:54 AM XXCoder: I really need to get a machinist handbook.
05:54 AM XXCoder: whats good cheap one?
05:55 AM jthornton: I'd have to get my shoes on then pet the cat then feed the cat then carry the cat around for a bit before getting to the shop
05:55 AM XXCoder: we have cat here for a week
05:55 AM XXCoder: shes 20 years old
05:56 AM Deejay: pretty old for a cat
05:56 AM jthornton: that's an old cat
05:56 AM XXCoder: quite old
05:56 AM XXCoder: my grandmother cat lived to be 25
05:56 AM jthornton: we had one that lived 18 years
05:57 AM XXCoder: I was 23 then. it was surreal meeting a cat older than me.
06:01 AM jthornton: hmm I did figure out that the leg x the square root of 2 = the hypotenuse... now to go the other way round lol
06:09 AM jthornton: finally the hypotenuse x the sign of the angle = the length of the leg
06:45 AM Tom_L: morning
07:07 AM JT-Shop: morning
07:07 AM XXCoder: yo
07:07 AM XXCoder: oh yea jt I wondered how powerful laser gonna be to engrave inocel lol
07:33 AM -!- #linuxcnc mode set to +v by ChanServ
07:43 AM elmo40: XXCoder, to engrave inconel? very powerful, but also the correct frequency. metal is demanding.
09:52 AM perry_j1987: morning
09:53 AM * jthornton ponders who will lay the first egg of the month and they are taking their time today
09:53 AM jthornton: morning
09:53 AM * jthornton goes back to lawn mower repairs
10:12 AM rmaw_ is now known as rmaw
10:40 AM Tom_L: finally finished compiling...
10:42 AM Tom_L: yay, it shows preempt-rt
10:43 AM jthornton: yippie!
10:43 AM jthornton: email me an extra usb mouse...
10:44 AM Tom_L: how do i go about getting lcnc on it now?
10:46 AM Tom_L: i should have done this on a faster pc to begin with but it's nearly done now
10:49 AM jthornton: http://gnipsel.com/linuxcnc/uspace/
10:50 AM Tom_L: i think that's where i'm at now
10:51 AM Tom_L: the lbuntu one is empty but i can probably use one of the others
10:51 AM jthornton: hmmm
10:52 AM jthornton: gimme a minute to upload that page
10:53 AM Tom_L: ok
10:53 AM jthornton: well crap, I've not updated the page with Lubuntu specific stuff
10:54 AM jthornton: it should be similar to the linux mint page
10:54 AM jthornton: might have different dependencies but dpkg-checkbuilddeps will let you know
10:58 AM Tom_L: ok
10:58 AM Tom_L: i'm in no rush anyway, working on a couple things here
10:58 AM Tom_L: just letting that run by itself until done
11:00 AM jthornton: ok I just uploaded the terse instructions for lubuntu
11:00 AM Tom_L: it would be nice if the latency on it was decent on the d525
11:01 AM Tom_L: not showing up yet
11:01 AM jthornton: none of my d525's work anymore
11:01 AM jthornton: I had 2 IIRC
11:02 AM Tom_L: been using it on the mill all along
11:03 AM jthornton: one the NIC crapped out, CRS why the other one died
11:03 AM Tom_L: what did you have on it for cards?
11:04 AM Tom_L: mesa cards..
11:04 AM jthornton: 5i25
11:04 AM Tom_L: i doubt ethernet would work on it
11:04 AM jthornton: it was on my BP mill
11:04 AM Tom_L: i've got an ethernet card i could use
11:05 AM * jthornton thinks it's time for a nap now
11:05 AM Tom_L: haven't had any issues with mine yet
11:06 AM Tom_L: your lbuntu page still doesn't show anything
11:15 AM mtpocketscnc: Hello all
11:15 AM Tom_L: hi
12:02 PM perry_j1987: hmmmm https://amzn.to/2Z1CsO2
12:02 PM jthornton: Tom_L: refresh your browser
12:49 PM Tom_L: i will once i return from some errands
12:50 PM Tom_L: did you run any latency tests with it?
01:18 PM JT-Shop: yea, run latency-histogram 1ms
01:36 PM CaptHindsight: Tom_L: what hardware are you trying this on?
01:38 PM CaptHindsight: we have some 5.x rt kernel with Sid running on new AMD Ryzen hardware
01:38 PM CaptHindsight: all the 3d accel works great
01:39 PM CaptHindsight: using an older RX570 card for multiple 4K displays
01:41 PM CaptHindsight: hah got a Chinese DC DC supply in today, the power mosfet isn't touching the heatsink, the standoffs are too long
01:43 PM pcw_home: is it a "GoodLuck" brand power supply?
01:50 PM CaptHindsight: heh, "Noname"
01:51 PM CaptHindsight: they even have a hole in the PCB and tapped hole in the heatsink for the mosfet mounting screw, but decided to leave that out :)
01:52 PM CaptHindsight: on the other hand the spacers are needed to keep the through hole compoenets from shorting to the heatsink, tradeoffs tradeoffs
01:55 PM Tom_L: CaptHindsight, D525
01:55 PM Tom_L: pretty old junk
01:57 PM CaptHindsight: base thread latency with preempt_rt is pretty poor
01:57 PM CaptHindsight: but only using servo on these
01:58 PM Tom_L: gonna test a 7i90 on the parallel port
01:58 PM perry_j1987: new endmill came in
01:58 PM perry_j1987: yay i didnt break it on first test either heh
02:01 PM CaptHindsight: I've bent a few
02:02 PM CaptHindsight: in a hurry using the MPG and forget to change axis, you think you're in Z but actually in X or Y and woops when you crank the dial
02:04 PM perry_j1987: all my endmills explode
02:04 PM perry_j1987: never bent one heh
02:04 PM perry_j1987: still not sure why they design them with explosive charges in every endmill...
02:04 PM Tom_L: CaptHindsight, it's a good stepper skip test :)
02:04 PM SpeedEvil: You can tell a really skilled machinist if they can bend carbide.
02:05 PM perry_j1987: hmm did bore op with this new endmill and holes came out smaller
02:06 PM perry_j1987: its always something to research ugh
02:10 PM CaptHindsight: is there some special magic to building LCNC packages for Debians?
02:10 PM perry_j1987: ok doublechecked the size of the tool in fusion360 and ran the simulation it all looks right
02:10 PM perry_j1987: it put the holes in the right spot...
02:11 PM perry_j1987: just appears helix to be smaller as it went down in
02:12 PM CaptHindsight: lash?
02:12 PM CaptHindsight: worn spindle bearings?
02:12 PM CaptHindsight: or is the G-code just not right?
02:12 PM perry_j1987: its new 6040
02:12 PM CaptHindsight: G-code good, but interpreter off?
02:13 PM CaptHindsight: missing steps?
02:13 PM CaptHindsight: perry_j1987: do other holes come out the correct size?
02:14 PM CaptHindsight: undersized mill?
02:16 PM perry_j1987: i dont believe it missed steps
02:16 PM perry_j1987: it put the multiple holes in right spots
02:17 PM Tom_L: CaptHindsight what would you say to be 'acceptable' latency numbers to run a mesa card off the pp?
02:17 PM Tom_L: i'm a ways from checking it... still installing stuff
02:18 PM perry_j1987: its 1/8 ballnose endmill
02:19 PM perry_j1987: doublechecked it was setup as that in fusion360
02:19 PM Tom_L: carbide?
02:19 PM Tom_L: what did those cost.. comparing to my local supplier
02:19 PM perry_j1987: ya carbide
02:20 PM Tom_L: i got a few 2 & 4 flute the other day
02:20 PM perry_j1987: it was 14.99 or something
02:20 PM perry_j1987: 4 flute
02:20 PM Tom_L: ~10 approx local
02:20 PM perry_j1987: this one has 1" flutes though
02:20 PM Tom_L: oh
02:21 PM Tom_L: well that makes a difference on carbide
02:21 PM Tom_L: but why so long?
02:21 PM perry_j1987: wanted to try milling a hole instead of drilling
02:21 PM perry_j1987: no automatic tool changer on the 6040 heh
02:22 PM CaptHindsight: pcw_home: Tom_L question ^^: what would you say to be 'acceptable' latency numbers to run a mesa card off the pp?
02:22 PM Tom_L: with a ballnose?
02:22 PM CaptHindsight: Tom_L: I don't recall, haven;t use the LPT fpga cards in a few years
02:22 PM Tom_L: what happens if it's too slow?
02:22 PM Tom_L: what to look for...
02:22 PM perry_j1987: i didnt know it was a ballnose when i ordered it
02:23 PM Tom_L: ahh
02:23 PM Tom_L: i sometimes plunge cut when necessary but with a flat mill
02:23 PM pcw_home: really for servo thread only, you just need to get all the I/O done in the allotted 1 ms time
02:24 PM Tom_L: if i ever get past all these damn dependencies i'll test it :)
02:25 PM CaptHindsight: now to find out if the mosfet will be shorted to the heatsink using a conductive fastener through its mounting hole
02:30 PM CaptHindsight: they sanded the part numbers off the chips
02:30 PM Tom_L: awesome
02:30 PM Tom_L: they're proprietary now
02:32 PM CaptHindsight: do any of the Chinese analog IC co's make any proprietary parts yet?
02:32 PM perry_j1987: heh apparently this 6040 hasnt got very repeatable endstops
02:32 PM perry_j1987: just homed it and test it going back through the same op
02:32 PM perry_j1987: oblong holes now in the test piece heh
02:32 PM CaptHindsight: perry_j1987: what does it use for home switches?
02:33 PM CaptHindsight: are they loose or just not very repeatable?
02:33 PM perry_j1987: omron inductive square looking ones
02:33 PM perry_j1987: yellow color
02:33 PM perry_j1987: or.... last time i was running and i zero'd it out maybe it had skipped steps during that round
02:33 PM perry_j1987: and the endstops are infact repeatable heh
02:35 PM Deejay: gn8
02:36 PM CaptHindsight: have to investigate and find the loosey goosey parts
02:36 PM perry_j1987: of course you'd say that :P
02:36 PM * perry_j1987 grabs tools heh
02:41 PM Tom_L: jthornton, how do you get linuxcnc to show up in the package manager?
02:41 PM Tom_L: or do you have to build it locally?
02:42 PM CaptHindsight: Tom_L: are you building a package or just LCNC?
02:42 PM Tom_L: i installed lbuntu and preempt-rt on it
02:43 PM Tom_L: added all the dependencies for lcnc i believe and downloaded the source
02:43 PM CaptHindsight: we just built it for Sid and added it to the task bar
02:43 PM Tom_L: so i'm guessing i need to build it
02:43 PM jthornton: you have to build it
02:43 PM Tom_L: of course you'd say that :)
02:43 PM CaptHindsight: vs packaging it
02:43 PM Tom_L: i forgot the command for the source thing
02:45 PM perry_j1987: everything appears tight on the 6040 still
02:48 PM CaptHindsight: maybe too tight and missing steps?
02:49 PM CaptHindsight: have to get the indicators out and start measuring
02:49 PM CaptHindsight: or cutting test patterns and measuring
02:49 PM Tom_L: i'm beginning to have my doubts if this will run
02:50 PM jthornton: why is that?
02:50 PM Tom_L: brouser is acting strange and i got an 'internal error' of some sort back from the OS
02:50 PM CaptHindsight: but if home is off every time you start you have to fix that
02:50 PM jthornton: you might try an older version to see if it is hardware related
02:50 PM Tom_L: jthornton, do you have the command to build 2.7 for this?
02:51 PM Tom_L: now that i came this far i'd at least like to try a latency test
02:52 PM perry_j1987: CaptHindsight i did have to adjust for skew in software
02:52 PM jthornton: debuild -uc -us
02:53 PM jthornton: but first checkout 2.7 with git checkout 2.7
02:54 PM Tom_L: thanks
02:54 PM Tom_L: seems to be building
02:54 PM Tom_L: why did i need all those language packages in the dependency list?
02:56 PM pink_vampire: hi
02:59 PM perry_j1987: Tom_L incase you hit your head and start speaking french
02:59 PM perry_j1987: then you can still CNC
02:59 PM perry_j1987: :)
03:03 PM CaptHindsight: low profile pc cases are getting hard to find
03:03 PM jthornton: I have no idea we don't even have polish or german but maybe it's for the translated stuff in the guis
03:04 PM Tom_L: well it's building so meh..
03:10 PM Tom_L: do you know how to create a launcher for it in lbuntu?
03:10 PM Tom_L: icon or menu
03:11 PM jthornton: right click on the deb and use gdebi to install it after it builds and the menus show up
03:11 PM jthornton: you need to install the docs en and emc
03:12 PM Tom_L: mmm
03:12 PM Tom_L: i put it in linuxcnc
03:21 PM JT-Shop: the debs?
03:28 PM * Tom_L looks confused
03:28 PM Tom_L: i put the source in linuxcnc and am building it from there right now
03:29 PM JT-Shop: ah ok the debs will be in your home directory when it's done
03:29 PM Tom_L: don't have a deb that i know of yet
03:29 PM JT-Shop: might take a while...
03:29 PM Tom_L: i'm sure on that thing
03:29 PM JT-Shop: you will get several debs
03:29 PM Tom_L: they didn't used to build debs did they?
03:30 PM JT-Shop: they?
03:30 PM Tom_L: the developers
03:30 PM Tom_L: sry, i've got about 4 projects going at once here...
03:30 PM JT-Shop: dunno, I assume they did to build the livecd
03:30 PM JT-Shop: just 4?
03:30 PM Tom_L: heh
03:31 PM JT-Shop: let me email you a couple more so it's an even half dozen lol
03:31 PM * JT-Shop gets back to changing the oil in the uplander
03:32 PM Tom_L: oh wow it finished
03:33 PM Tom_L: i want the uspace one right?
03:33 PM JT-Shop: yea
03:33 PM Tom_L: oh nm, the rest look like docs
03:33 PM JT-Shop: pick the en one
03:34 PM Tom_L: :)
03:43 PM Tom_L: 6997123 servo thread 148556 base thread :D
03:43 PM Tom_L: not so good
03:45 PM perry_j1987: running test now
03:46 PM Tom_L: so, back to wheezy on the D525
03:46 PM perry_j1987: initial fusion360 code was setup for climb milling on the bore
03:46 PM perry_j1987: doing test with conventional
03:46 PM perry_j1987: it defaults to climb
03:46 PM Tom_L: if they fix 2.8 i'll try it again on wheezy but the 'run from here' seems broke which is a handy tool to not have
03:46 PM JT-Shop2: don't run the base thread
03:47 PM JT-Shop2: latency-histogram 1ms
03:47 PM Tom_L: how do i turn it off?
03:47 PM JT-Shop2: or latency-test --help
03:48 PM JT-Shop2: latency-histogram --help
03:48 PM JT-Shop2: latency-plot --help
03:48 PM JT-Shop2: that's all
03:51 PM Tom_L: --help integer expression expected
03:51 PM Tom_L: error: thread 'fast' not found
03:51 PM perry_j1987: well there goes that endmill
03:51 PM perry_j1987: another one bites the dust
03:52 PM perry_j1987: didnt touch speeds and feeds it just out of blue started running like bat out of hell
03:52 PM perry_j1987: starting to get tired of this lol
03:52 PM JT-Shop: what kind of drive is it?
03:53 PM Tom_L: ssd
03:54 PM JT-Shop: no perry_j1987
03:55 PM Tom_L: oh
03:55 PM perry_j1987: its a 6040 cnc ballscrew 2.2kw watercooled spindle with something called mach controller card inside
03:55 PM JT-Shop: ouch
03:55 PM JT-Shop: you running mach?
03:56 PM perry_j1987: ya it was my first foray into cnc world and the controller is usb card
03:56 PM JT-Shop: I'd say buy a lot of endmills or get a different stepper driver and use LinuxCNC
03:57 PM JT-Shop: even the TB6560 is better than using mach
03:58 PM JT-Shop: hmm I see a tb6600 now
03:58 PM JT-Shop: opps nevermind on the tb6600 it's too expensive for that controller
03:59 PM perry_j1987: the box has a vfd and individual stepper drivers and the controller card and a psu
03:59 PM perry_j1987: i could swap out the the controller for one of those parallel breakout boards i guess
03:59 PM JT-Shop: so they only thing that is usb is the controller?
03:59 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/tom-01Jun2019-53.png
04:00 PM JT-Shop: dang the tb6600 cost almost as much as a 7i96... no question use the 7i96
04:02 PM JT-Shop: latency-histogram --nobase
04:02 PM JT-Shop: or latency-test 1ms
04:03 PM Tom_L: heh, the whole screen turned blue
04:03 PM JT-Shop: perry_j1987: https://mesaus.com/index.php?route=product/product&product_id=150&search=7i96
04:03 PM perry_j1987: ya https://www.aliexpress.com/item/XHC-6-axis-mach-3-motion-control-card-cnc-interface-board-MK6-5-axis-controller/32429338022.html it has one of these in it
04:03 PM JT-Shop: for which one?
04:04 PM JT-Shop: damn $353.39 for that plus $34.26 shipping
04:04 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/tom-01Jun2019-53.png
04:04 PM JT-Shop: I hope you didn't pay that much
04:05 PM JT-Shop: Tom_L: that looks much better
04:05 PM Tom_L: useable?
04:05 PM JT-Shop: sure
04:05 PM JT-Shop: Mesa card?
04:06 PM Tom_L: once i finish up a couple things here i might try it
04:06 PM Tom_L: 7i90 on the parport
04:08 PM JT-Shop: that one I'm not very familiar with, maybe pcw_home will chime in?
04:09 PM Tom_L: what about ethernet?
04:09 PM Tom_L: 7i80
04:09 PM perry_j1987: no i didnt heh
04:09 PM perry_j1987: it was in the cnc i got the whole 6040 with a nice pendant and collet set and some other odds and ends for 1200 or so
04:10 PM perry_j1987: others that had all this specs were selling for 1800-2600 at the time
04:10 PM JT-Shop: did you see the link for the 7i96?
04:15 PM Tom_L: ok, one fire out..
04:18 PM perry_j1987: hmm
04:18 PM perry_j1987: is that 7i96 some sort of little arm board?
04:19 PM JT-Shop2: no
04:19 PM JT-Shop2: it's a spartan chip
04:19 PM perry_j1987: fpga then
04:21 PM JT-Shop: aye
04:35 PM perry_j1987: be nice if could just use some raspberry pi zeros for io
04:37 PM CaptHindsight: where has all the low cost dual core intel mini-itx boards gone?
04:37 PM perry_j1987: CaptHindsight look up atomic pi
04:37 PM perry_j1987: quad core
04:37 PM perry_j1987: 35 bucks
04:40 PM tjb1: Anyone here use Cimco NC Base or Predator PDM?
04:42 PM CaptHindsight: perry_j1987: yes, I've crawled through their shitty docs
04:42 PM perry_j1987: Its still new
04:43 PM CaptHindsight: no PCIe or LPT from what I recall
04:49 PM XXCoder: elmo40: interesting! so must be quite specialized company. considering how many tools we destroy on those jobs, well worth it, likely.
04:50 PM CaptHindsight: https://www.ebay.com/itm/MiTAC-PD11TI-Low-Profile-Mini-ITX-Motherboard-Intel-Atom-N2800-1-86GHz-NM10/352618359658
05:01 PM perry_j1987: CaptHindsight its using pcie for the wifi/bt and such it looks like
05:04 PM CaptHindsight: i also need ram slots
05:05 PM CaptHindsight: https://www.asrock.com/MB/Intel/J4005B-ITX/index.asp has it all except its ASRock
05:16 PM Tom_L: you don't like ASRock?
05:16 PM CaptHindsight: broken BIOS
05:17 PM CaptHindsight: as broken as BIOS is to begin with Asus and SuperMicro tend to do the best jobs
05:18 PM CaptHindsight: followed by Gigabyte
05:18 PM CaptHindsight: them MSI ASRock and low on the list Biostar
05:19 PM tjb1: I have a D525MW setup if anyone is interested?
05:19 PM CaptHindsight: best of course is using coreboot
05:19 PM CaptHindsight: tjb1: have 2?
05:20 PM tjb1: no

05:21 PM CaptHindsight: tjb1: what card is that in the PCI slot?
05:22 PM CaptHindsight: 2nd LPT?
05:22 PM tjb1: yes
05:23 PM tjb1: It was for this https://www.cnc4pc.com/c10-bi-directional-parallel-port-interface-card.html

05:35 PM perry_j1987: I have a few amde350 boards in this server rack
05:35 PM perry_j1987: 16 gigs of ram on them dual core amd atom equivalent
05:36 PM CaptHindsight: https://www.amazon.com/PD14TI-HN-Mini-ITX-Motherboard-Parallel/dp/B071JJJ4WV/ref=pd_rhf_dp_s_pop_srecs_sabr_1_5/137-4748236-3645356?_encoding=UTF8&pd_rd_i=B071JJJ4WV&pd_rd_r=05c72281-d9d4-4c49-b412-aa4187e9f2c1&pd_rd_w=zb2t2&pd_rd_wg=uvLSg&pf_rd_p=b2f690dc-2d59-47f6-8525-ac277f41ffca&pf_rd_r=RE6SA6XGX840P6DHKCN0&psc=1&refRID=RE6SA6XGX840P6DHKCN0
05:36 PM perry_j1987: gigabyte boards
05:36 PM CaptHindsight: have never use an Intel board for LCNC in 15+ years
05:40 PM perry_j1987: ya this is the one in this 6040 for sure http://www.cdxhctech.com/html/eProduct/view_337.html
05:43 PM flyback: make sure you use a decent psu
05:43 PM flyback: one with a crowbar
05:43 PM flyback: some people use old server psus and wire them up
05:43 PM flyback: I have a 730 watt it's 12v@60a and a 3.3 always on line
05:43 PM flyback: crowbar owns your "canuck"
05:43 PM * flyback dropkicks perry_j1987
05:43 PM flyback: oh sorry, your nick sounded canadian
05:44 PM perry_j1987: what? lol
05:44 PM flyback: :P
05:44 PM flyback: for anyone who doesn't know a crowbar is a gun with the trigger tied to a door knob
05:44 PM flyback: inside a power supply
05:45 PM flyback: if the psu supply control goes apeshit and is about to spike everything to death with high voltage
05:45 PM flyback: the crowbar triggers and dead shorts the psu
05:45 PM CaptHindsight: an a kick to the canards
05:45 PM flyback: destroys the psu but saves everything attached
05:46 PM flyback: I think they are pretty standard even on low end ones now
05:46 PM flyback: bbut I rememeber "the dark times" in the pc world
05:46 PM flyback: doctor customer of ours had a white box pc someone made him
05:46 PM flyback: BLEW THE CHIPS OFF THE HARD DRIVE PCB
05:46 PM CaptHindsight: psu = pretty sure uh
05:46 PM flyback: shitty powmax (#1 fire starter brand) with no over voltage protection
05:47 PM flyback: even the keyboard and mouse were fried
05:48 PM perry_j1987: probably unplugged and plugged in the ps2 keyboard while power was on and took out the local nuclear power plant
05:54 PM flyback: still bummbed out aussie50 and a friend of mine killed themselves this week
05:55 PM XXCoder: what happened?
05:59 PM flyback: dunno about aussie
06:00 PM flyback: my friend had cancer, was kicked out of his head by his wife and living in his car
06:00 PM flyback: decided to end it
06:00 PM flyback: head/house
06:00 PM XXCoder: that really sucks
06:01 PM XXCoder: I mean, no support
06:03 PM jthornton: wow that sucks
06:06 PM jthornton: XXCoder: I've got my simple part generator working with my nesting on the plasma gui
06:07 PM XXCoder: that is awesome'
06:07 PM XXCoder: make part design then nest it and ready to run
06:09 PM jthornton: yea the complicated parts need to be in the form of a subroutine
06:09 PM jthornton: so far I can generate a rectangle of any size with a lead in arc and lead out arc
06:10 PM jthornton: did you see the nesting video?
06:11 PM XXCoder: think so. last week something?
06:12 PM jthornton: yea
06:12 PM XXCoder: lots of L shaped parts nested into grid
06:12 PM jthornton: aye
06:12 PM jthornton: what's cool is being able to rotate the parts and have an X offset on the even rows
06:13 PM jthornton: dunno if anyone on the forum noticed or not no one commented
06:13 PM XXCoder: nice myfordboy casting video hes making car part for discountuned car
06:13 PM jthornton: new one?
06:13 PM XXCoder: nice! I can see use of that offset. some parts is better laid offset to each opther
06:13 PM XXCoder: more cpompact
06:13 PM XXCoder: one day ago uploaded
06:13 PM jthornton: yep and you can see the result instantly of your changes
06:15 PM XXCoder: thats good
06:26 PM XXCoder: lol closest to failure myfordboy ever had
06:26 PM XXCoder: some metal leaking on mold
06:26 PM XXCoder: he stops it by water sprayer
06:28 PM jthornton: damn something smells good
06:37 PM XXCoder: crazy https://www.youtube.com/watch?v=JldTYkcFDM8&
06:59 PM Tom_L: jthornton, must be food nearby
07:03 PM Tom_L: XXCoder, but why?
07:03 PM XXCoder: ours is not to question why!
07:03 PM XXCoder: ;)
07:05 PM XXCoder: I dont know why guy needs such an giant battery
07:06 PM Tom_L: powered skateboard?
07:06 PM Tom_L: i keep seeing a guy riding one of those downtown
07:07 PM XXCoder: maybe? dunnp
07:07 PM elmo40: have you seen what happens when large Lion batteries catch fire?
07:07 PM elmo40: they don't stop burning!
07:08 PM Tom_L: yeah
07:08 PM Tom_L: you can't put em out afik
07:08 PM elmo40: there was one episode of that british car show... james and captain slow and them... the guy raced an electric can, ran off the track and totalled it.
07:08 PM elmo40: caught fire. was put out, then re-lit again!
07:09 PM Tom_L: i think i saw that
07:09 PM elmo40: self fueling and self oxyginating
07:09 PM Tom_L: good combination.
07:09 PM Tom_L: let's put that in a car
07:09 PM Tom_L: :)
07:09 PM Loetmichel: elmo40: define large
07:10 PM Tom_L: Loetmichel it was in an electric car
07:10 PM Loetmichel: and they DO stop burning. not with water as coolant though
07:10 PM XXCoder: if its hot enough it can take water crack it for oxygen
07:10 PM XXCoder: and use hyrogen as fuel too
07:10 PM Tom_L: cars equiped with them should also have build in extinguishers
07:11 PM XXCoder: lathinium ion is good battery between crap batteries an better future batteries
07:11 PM Loetmichel: Tom_L: teslas have the next best thing: they have a battery cooling system
07:12 PM Loetmichel: so even it ONE cell runs away and explodes the others will stay cool enough to not "chain-react"
07:12 PM XXCoder: nice
07:12 PM Tom_L: wonder how well that was tested
07:12 PM XXCoder: theres people who buy used telsa battery pack and replace few cells, then use it for house power
07:12 PM Loetmichel: thats the problem that occured with hamster: the batteries of the supercar chain-reacted
07:12 PM Loetmichel: one caught fire and heatet the other ones to failure, too
07:13 PM Wolf__: enough tesla cars on the road, if there was a battery system fire issue it would be all over the news
07:15 PM Tom_L: they should come with a wind turbine charger. instead of moving the fuel to a fossil fuel or nuclear electric plant
07:16 PM XXCoder: even with coal power ultimately electric car makes less pollution, though yeah better to have that
07:16 PM XXCoder: I wonder if setup home station, can connect it to solar panels and wind fan
07:16 PM XXCoder: combined is 1k
07:16 PM Wolf__: blah, then I wont be able to get a tesla so I can claim that I have a coal powered car
07:16 PM XXCoder: 1 kwh kit saw one of those
07:17 PM XXCoder: lol
07:17 PM Tom_L: just build one of those wood fired engines
07:18 PM Tom_L: you stop at the light, you can hop out and stoke the fire
07:18 PM Wolf__: really tho, the efficiency on the tesla model 3 is pretty impressive, like 200w per mi or something like that
07:18 PM Tom_L: what's the cost per mile over the vehicle life expectancy?
07:19 PM Tom_L: it's gonna have to be alot lower before the GP catches on
07:20 PM perry_j1987: well that did not seem to work heh
07:20 PM Loetmichel: Tom_L: lithium batteries only catch fire if they overtheat.
07:20 PM Wolf__: I think it falls less then IC cars
07:20 PM Tom_L: perry_j1987 too much tool deflection on that long cutter?
07:20 PM perry_j1987: tried making first rotary axis code with fusion360
07:21 PM perry_j1987: Tom_L no i had the cutter choked up i broke that cutter already haha
07:21 PM Loetmichel: and there are only 2easons for overheat: overcgarge or short circuit
07:21 PM Wolf__: or bad cell
07:22 PM Loetmichel: Wolf__: bad cell results in overcharge/discharge
07:22 PM Loetmichel: hence in overheating
07:22 PM XXCoder: or age
07:22 PM Wolf__: true
07:23 PM Tom_L: i suppose they put temp monitors on each cell
07:23 PM CaptHindsight: what if you crush them with a vise?
07:24 PM Tom_L: you may fuse the vise shut?
07:24 PM CaptHindsight: why do we always blame temperature?
07:24 PM Wolf__: they are grouped, think they are fused, monitored and cooled in set
07:24 PM Loetmichel: there were tests made withe a tesla module. as ling as the cooling system can cope with the heat even a single/few burning cells dont damage the surrounding ones
07:25 PM Tom_L: that's comforting when my arse is sitting em
07:25 PM Tom_L: on em*
07:25 PM Loetmichel: you dont
07:25 PM Tom_L: you're right
07:25 PM Wolf__: https://www.ebay.com/itm/Tesla-60kWh-OEM-Lithium-Battery-Module-22-8V-4-5kWh-18650-384-Panasonic-Cells-/153445855985
07:26 PM Loetmichel: in a tesla they are below the chassis
07:26 PM elmo40: Loetmichel, i guess any size. it is all the same chemicals.
07:26 PM XXCoder: 60 kwh dang
07:26 PM elmo40: but volume helps sustain and concentrate the heat, causing more damage
07:26 PM XXCoder: can be used with badass solar setup
07:26 PM Loetmichel: there is at least two layers of steel between you and the modules
07:27 PM CaptHindsight: so Teslas are more dangerous in hot weather
07:28 PM CaptHindsight: if it's -50C they won't catch fire as easily as if it's 40C
07:28 PM Loetmichel: elmo40: indeed, but lots of small cells have the advantage of smaller energy output when burning. thats easier cooled than a few big 200ah cells and one burning :-)
07:29 PM Loetmichel: at -40c they will not cathch fire at all
07:29 PM Wolf__: if you look at the pics of the tesla pack in that ebay listing you can see the coolant tubes in it
07:29 PM XXCoder: lower power loss when dead cell is bypassed also
07:29 PM Tom_L: i wonder if they have circutry to allow for a 'few bad cells'
07:29 PM XXCoder: cheaper to swap cells
07:30 PM Loetmichel: reactions are way to slow at that temp to even ignite
07:31 PM tjb1: CaptHindsight: did you want the 525?
07:31 PM Loetmichel: Tom_L: each cell in a tesla module has a fuse wire
07:32 PM Loetmichel: so if one fails you only lose about 8% capacity or so
08:03 PM CaptHindsight: tjb1: I need new and more than one of the same
09:00 PM norias: hi
09:19 PM norias: i've never run any cnc swiss machines
09:20 PM norias: anyone know what the max stock size usually is?
09:21 PM norias: nevermind, found some stuff
11:40 PM net|: https://github.com/lakemawu2/omnidirectional-robot does this factor in wheel size ?
11:40 PM net|: could probably make a larger one for printing houses
