12:08 AM pink_vampire: not sure if i even saved it it was just a quick stuff
03:35 AM Deejay: moin
04:22 AM XXCoder: man~~
04:22 AM XXCoder: was busy alll day
04:22 AM pink_vampire: woman
04:22 AM XXCoder: went to deaf students event, talked about working
04:23 AM pink_vampire: sounds interesting
04:25 AM XXCoder: it was
04:25 AM XXCoder: i got back to work t 7 pm so i worked just over 5 hours
04:28 AM XXCoder: glad I went even though it cost me some hours of work lol
04:29 AM pink_vampire: sounds like you have fun working there
05:04 AM jthornton: morning
05:05 AM XXCoder: pink_vampire: I did
05:05 AM XXCoder: it was pretty great event. look forward to it next year.
05:05 AM XXCoder: wish I bought in more examples though
05:09 AM Tom_L: morning
05:15 AM jthornton: morning
05:15 AM XXCoder: morning
05:15 AM Tom_L: any rain over there?
05:16 AM Tom_L: supposed to here but not yet
05:16 AM weenerdog: goood mawnin
05:18 AM jthornton: supposed to be sunny here today but rain friday and saturday
05:19 AM jthornton: hmm the tomato seeds have been in the germination box for 10 days now at 85°F and no sign of life yet
05:21 AM weenerdog: gently probe one or two with a toothpick and see if they're doing anything. thats a little warm too. have you had good luck at that temp before?
05:22 AM weenerdog: i dunno is why i'm askin. i've never germinated except room temp, which is generally in the 60s here except the living rm
05:22 AM jthornton: all the seed packs say ideal temperature 75-95 so I picked the middle as a tomato is a tropical plant
05:22 AM weenerdog: heh never read the pack. oughtta be fine then
05:23 AM jthornton: it's my first time trying to use the fermentation box for germination
05:23 AM jthornton: do you cover yours up until the sprout?
05:23 AM weenerdog: nah
05:23 AM jthornton: I've been spritzing them with water twice a day
05:24 AM weenerdog: when i have done "other" (shhhh) seeds in the past, i've covered a rubber tub with plastic wrap and kinda made a terrarium
05:24 AM XXCoder: heh only thing i tried to grow was certain tree
05:24 AM XXCoder: seed is very hard to start growing, and i failed few times
05:25 AM jthornton: I think I'll put the cover on for a while, it gets pretty dry pretty quick
05:25 AM weenerdog: i have the best luck with the little peat moss cups. they're flat til you soak'em. put them in a plastic container or dish with maybe 3/8" of water in it, cover with plastic wrap. dont have to touch'em til you see green
05:26 AM weenerdog: i get a high germination percentae like dat
05:27 AM weenerdog: but my favorite way to germinate tomato plants is there is this discount store here that always buys way to many plants and puts them on death row for a dollar a flat of 6 (and 1/2 of them have 2 in'em) :)
05:28 AM weenerdog: they look like hell when i get them but they all live and get pretty
05:28 AM weenerdog: are these heirloom seeds, jt?
05:28 AM jthornton: yea we have a place that grows them for wholesale and you can get a flat for $5 like 24 plants
05:29 AM jthornton: yea cherokee purple, german lunchbox
05:29 AM weenerdog: the heirlooms are a different animal. these might just be long germinating cultivar. they like it wet.
05:30 AM jthornton: ok good to know, I think I'll put some water in the bottom tray
05:30 AM jthornton: need to take apart my raised bed and rework it into a different configuration
05:31 AM weenerdog: i put my tomatos where i've burned a brush pile and they grow the tack welds on the little cages apart sometimes
05:38 AM jthornton: they like the slightly acidic soil for sure, I guess the ash makes it lower the ph?
05:40 AM weenerdog: no its alkaline, oddly
05:40 AM jthornton: the wood ash?
05:41 AM weenerdog: i just tried it and had good luck.
05:41 AM weenerdog: ya
05:41 AM jthornton: odd
05:41 AM jthornton: I save the ash from my heaters for the chickens dust bath, I might mix some in the soil of the raised bed
05:45 AM jthornton: Tom_L: did you make that change to pyvcp?
05:53 AM weenerdog: 57 today, 62 tomorrow, 61 saturday then back to typical cold & rainy. may have to fire up the four wheeler this weekend.
07:26 AM Tom_L: JT-Shop i did but only locally
07:27 AM Tom_L: needs testing
07:35 AM jthornton: seems to work for me :)
10:28 AM asdfasd1: any idea what can be used as relatively pure iron anode? something easy to find? with minimum other metals?
10:30 AM Jymmm: used brake disc or drum
10:32 AM asdfasd1: they are very fragile I think, which make me think they are far from pure?
10:34 AM Jymmm: Well, I suppose you could work an ore mine instead =)
10:34 AM asdfasd1: haha
10:35 AM asdfasd1: I was looking around for something soft, but whatever I tried have too much other metals
10:35 AM asdfasd1: nails have too much copper
10:36 AM asdfasd1: steel wire have something else, not sure what it is
10:37 AM asdfasd1: the guy where I took the idea says "malleable cast iron washer in the bottom as a spent anode."
10:38 AM asdfasd1: but not sure what type of washer is that, my washers are not so good
10:40 AM jdh: iron skillet
10:42 AM asdfasd1: thanks about that, I have to find one now and destroy it haha
10:50 AM ziper: is carbon an issue?
10:52 AM jdh: yes, it is destroying the climate
10:54 AM ziper: is carbon in your iron an issue?
10:59 AM Loetmichel: Jymmm: mined raw iron is usually VERY high carbon content
11:00 AM Loetmichel: to the point that the ignots break when you knock them on a desk corner
11:03 AM asdfasd1: ziper: carbon probably not an issue, but other metals should be minimum
11:05 AM ziper: looks like plain cast iron has <1% manganese and barely anything else
11:06 AM asdfasd1: I should be looking for cast iron then
11:06 AM asdfasd1: thanks for the advises
11:07 AM JT-Shop: got some kind of critter in the new shop...
11:08 AM Rab: asdfasd1, lots of older car parts are cast iron. Connecting rods in particular are supposed to be malleable cast iron.
11:09 AM Rab: But that is a high-performance application relative to other parts of the engine, so maybe they have special stuff added.
11:11 AM asdfasd1: Rab: thanks, I had somewhere casted bearing housing, but cant find it now...
11:17 AM Jymmm: Loetmichel: Ah ok, mostly meant as a joke
11:59 AM fragalot: 'sup
01:49 PM Lcvette: https://youtu.be/zTXBCbFdMTY
01:49 PM Lcvette: success!
01:49 PM Lcvette: for the sim
01:49 PM Lcvette: now we can tie in the rest of the qml
01:49 PM Lcvette: for the in gui atc wheel
01:49 PM Lcvette: :D
01:49 PM Lcvette: \o/
01:53 PM pink_vampire: Lcvette: WOW, this is the most beautiful interface i ever saw for linuxcnc - this is look amazing
01:53 PM Lcvette: thanks!
01:54 PM Lcvette: theres alot of us working to make it
01:54 PM pink_vampire: what is based on?
01:55 PM Lcvette: QtPyVCP
01:55 PM fragalot: Lcvette: I have to say. That looks fantastic.
01:55 PM Lcvette: https://qtpyvcp.kcjengr.com/
01:57 PM Lcvette: fragalot: thanks!
01:57 PM Lcvette: like i said there are many putting forth a great deal of effort to bring about a new way to make updated gui's easy
01:57 PM pink_vampire: so this is going to replace the Axis gui?
01:57 PM Lcvette: or easier
01:58 PM pink_vampire: sounds amazing!
01:58 PM Lcvette: its just another option, there are several already built in the link i sent you being tested
01:59 PM Lcvette: Probe Basic is just the most involved of them all
01:59 PM Lcvette: which is the one in the video link
02:01 PM Lcvette: JT is working on some super cool stuff as well with conversational
02:03 PM pink_vampire: what kinda stuff?
02:12 PM pink_vampire: Lcvette: I can help with probing, and ridgid tapping
02:26 PM Lcvette: that would be awesome!
02:27 PM Lcvette: we have some probing done already but we need to finish up the controller programming for it before we can start writing all the macros
02:27 PM Lcvette: all the buttons are there along with in screen help
02:27 PM Lcvette: its a little bit different then you may be used to though
02:28 PM pink_vampire: mmm
02:28 PM Lcvette: but i saw your probe routines and they look great!
02:28 PM methods_: ahhh probing
02:28 PM pink_vampire: do i need to install something ?
02:28 PM methods_: https://vangogh.teespring.com/v3/image/f9hTbpy43y5IqpOeT3OKDhlxwTI/756/560.jpg
02:28 PM Lcvette: i think you could see what we were doing and it would click
02:29 PM Lcvette: yeah you would need to do the devel install
02:29 PM Lcvette: but we aren't quiote to the probing portion yet
02:29 PM Lcvette: hazzy needs to finish the subcall backend portion
02:30 PM pink_vampire: I'm with the 2.7.8 linuxcnc
02:31 PM Lcvette: this is all in master 2.8
02:31 PM Tom_L: Lcvette see you didn't really need my help
02:32 PM Lcvette: JT helped me this monring
02:32 PM Tom_L: JT-Shop if you think somebody could use that, i'd say add it in if you want
02:33 PM Lcvette: Tom_L: JT helped me see around my mental block this monring
02:33 PM Tom_L: well a good kick in the pants is really all you needed
02:34 PM Tom_L: it is pretty cool
02:35 PM Lcvette: once he pointed out it was the P0 that correlated to the motion.digital-out-00 and i sorted my excel table by the Px column i saw everything make perfect sense and was able to hash it out from there
02:35 PM Tom_L: yeah that's the pin number
02:35 PM Tom_L: P0..3
02:35 PM Lcvette: that is what i did not realize
02:36 PM Tom_L: i thought you got that from yesterday sry
02:36 PM pink_vampire: what is the benefit of the simulation?
02:36 PM Lcvette: i was thinking the Mx was a customized code of sorts
02:36 PM Lcvette: pink_vampire: without it, you cannot run through the M6 remap macros
02:36 PM Lcvette: it errors out
02:37 PM Lcvette: like trying to home with no home switches
02:37 PM Lcvette: so you use the sim to simulate so you can run through the tool change process
02:37 PM Lcvette: now turboss, hazzy etc can do coding for the atc stuff without having an actual atc to test
02:39 PM pink_vampire: but there is no part on the simulation, and it is all happen in real time as the machine move, it is not easier just look at the machine?
02:39 PM fragalot: pink_vampire: the idea is you do it WITHOUT the machine moving
02:39 PM fragalot: see if it's going to do anything weird and unexpected
02:40 PM pink_vampire: I see, this is going to be grate!
02:43 PM Lcvette: pink_vampire: most of the work done is not even near a machine
02:43 PM Lcvette: sim will be helpful for probe routine testing as well
02:46 PM pink_vampire: so it is display the toolpath in the sim?
02:48 PM Lcvette: mmmm, not sure
02:48 PM Lcvette: but it will in the backplot
02:49 PM pink_vampire: what is the "backplot"?
02:49 PM pink_vampire: the regular tool path display?
02:49 PM Tom_L: yes
02:49 PM pink_vampire: I see
03:30 PM JT-Shop: Tom_L: add what?
03:41 PM SpeedEvil is now known as Guest64462
04:30 PM Tom_L: JT-Shop the bar widget mods
04:30 PM Tom_L: if you want
04:55 PM Deejay: gn8
05:23 PM BitEvil is now known as SpeedEvil
06:02 PM Loetmichel: *snicker* just changed my wifes asus UX307f battery... it went "pregnant" a few weeks ago, so i ordered a replacement battery, today wife said id didnt boot any more, not even with the PSU connected... NICE haul: two of three pouch cells doubled in thickness, one tripled. All have 0V... and that thing isnt older than maybe a year or so.
06:14 PM pink_vampire: Loetmichel: is that an original battery?
06:19 PM Loetmichel: yes, it was
06:19 PM Loetmichel: the replacement isnt though
06:19 PM Loetmichel: ebay, cheapest
06:19 PM Loetmichel: we'll see how long THAT will last ;)
06:23 PM pink_vampire: hope it will no go on fire
06:24 PM Loetmichel: which one?`
06:25 PM Loetmichel: the new? unlikely
06:25 PM Loetmichel: it has only a small capacity
06:25 PM pink_vampire: so it ill be just a smaller flame
06:55 PM _unreal_: hay guys not sure which to choose? https://pastebin.com/Jn7QU81X
06:55 PM _unreal_: trying to compile the RT
06:57 PM _unreal_: hello?
06:58 PM ronox: hey anyone here use a taig mill before
07:00 PM _unreal_: not me
07:00 PM _unreal_: I'm trying to figure out what kind of RT kernel to compile
07:04 PM jthornton: what version of linuxcnc?
07:04 PM jthornton: Fully Preemptible Kernel (RT) (PREEMPT_RT_FULL) (NEW)
07:05 PM jthornton: _unreal_: that's the one you want for uspace
07:05 PM pink_vampire: ronox: i have the g0704, the taig is smaller
07:06 PM _unreal_: jthornton, ok...
07:06 PM _unreal_: figures I just CTRL+C'ed my progress ment to copy from CLI
07:06 PM _unreal_: stating over again
07:06 PM _unreal_: sigh
07:06 PM _unreal_: [ warn ] * [l][c] patch-4.19.31-rt18.patch [ failed ]
07:06 PM jthornton: have fun
07:07 PM _unreal_: when it finishes thisnext part it ask's which RT patch type to use
07:09 PM ronox: i wanna buy a taig, initially manual but eventually to do cnc, ive heard they are good but wanted to find someone with one that could tell me anything
07:10 PM jthornton: hmm I patch then build
07:11 PM ronox: ive decided to designate my upcomming tax return to buying a taig
07:11 PM * jthornton hates to get a tax return
07:12 PM _unreal_: jthornton, patch then build?
07:12 PM _unreal_: I guess thats what I'm doing
07:12 PM _unreal_: jthornton, https://pastebin.com/hNYs1AAK
07:12 PM _unreal_: I assume pre-empt is not working
07:13 PM _unreal_: there are no [ ] marks for pre-empt
07:13 PM ronox: mainly im trying to find out what upgrading the lead screws to ball would entail
07:13 PM jthornton: _unreal_: http://gnipsel.com/linuxcnc/uspace/linuxmint19-rt.html
07:14 PM jthornton: that's the way I build for linux mint 19
07:14 PM jthornton: ronox: you might have better luck on the forum
07:14 PM _unreal_: I'm trying to build for armbian
07:14 PM _unreal_: jthornton, I'm trying to get my tinker board up and running linuxcncn
07:15 PM ronox: yeah i figured as much, just thought it would be worth a shot to try here first
07:15 PM jthornton: that may help guide you dunno, never built for armbian... I think Peter has
07:15 PM ronox: one other thing then, does backlash matter as much when you are machining manually?
07:15 PM _unreal_: would love all the help I can get
07:16 PM jthornton: ronox: yea
07:16 PM _unreal_: jthornton, the other issue is I have to cross compile
07:16 PM ronox: could you elaborate on how?
07:17 PM ronox: or when its difficult to compensate
07:17 PM jthornton: well if the mill lead screws are sloppy it's hard to hold a tolerance
07:18 PM ronox: what, like when you basically do blind movements with your only refference being the x/y/z dial?
07:19 PM jthornton: yea
07:19 PM jthornton: plus you get a crappy finish if the leadscrews are sloppy
07:19 PM ronox: wwell, on the taig they arent sloppy i know that much
07:19 PM * jthornton goes to tuck the chickens in and do a bed check

07:33 PM Jymmm: Bayer bought Monsanto last year
07:36 PM ronox: ooh, i forgot to ask this, or keep forgetting, does anyone like smelt their own metal ingots to mill stuff from?
07:36 PM ronox: like brass or aluminium
07:36 PM Tom_L: Jymmm are they lacing their asprin now?
07:36 PM Jymmm: Probably
07:37 PM Tom_L: ronox it's not that pure if you plan to do something important with it
07:37 PM ronox: nah just for like screwing around
07:37 PM Tom_L: you don't know what alloy you have
07:37 PM Tom_L: or how it will machine
07:37 PM ronox: like from scraps
07:37 PM Tom_L: i know somebody that has been collecting ingots
07:38 PM Tom_L: not sure if he's done any casting or not yet
07:38 PM ronox: i was also thinking of setting up a large plastic reclaimer
07:38 PM ronox: to mill stuff with
07:39 PM ronox: anyway i do realize that smelting will shift the concentrations and such
07:41 PM ronox: i just wanted to know, with brass and alu, mainly brass though, if recycling it has some significant consequences, besides slag being destructive to bits and certain aluminium alloys not being castable
07:42 PM ronox: i dont have anything specific in mind but i am just thinking mainly of bulky stuff i dont want to buy huge chunks of metal to make, or things where id want to first mould it, like imagine milling a brass wineglass
07:43 PM ronox: the massive expensive lump of metal youd have to machine down to like $10 worth of metal or something
07:58 PM skunkworks: https://youtu.be/7LAtx8o48jI
08:52 PM Tom_L: skunkworks so you can set a wattage limit on the pid so you will stay within the power range of your system?
08:56 PM skunkworks: that is the thought.. set it to 750w and the feed will slow when the wattage is avo
08:56 PM skunkworks: above that
08:57 PM Tom_L: (found some earbuds and re'watched it :D)
08:57 PM Tom_L: cool stuff
08:57 PM Tom_L: what commands control adaptive feed?
08:58 PM skunkworks: m53? i would have to look
08:58 PM Tom_L: or is that part of the config
08:58 PM Tom_L: 52.. thanks
08:58 PM skunkworks: you turn it on.,. then the motion.adaptivefeed pin workd
08:58 PM skunkworks: works
08:59 PM Tom_L: and what do you feed that pin to?
08:59 PM skunkworks: currently the output of the pid comparing setpoint to spindle power
09:00 PM Tom_L: so you need a way to read the spindle power
09:00 PM skunkworks: yes.. stmbl has it
09:01 PM Tom_L: my sherline doesn't
09:01 PM skunkworks: add a current ring?
09:01 PM skunkworks: :)
09:02 PM Tom_L: i made one for a windmill generator but never tested it
09:07 PM pink_vampire: skunkworks: look super cool!!!
09:09 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/hall/HallSensor3.jpg
09:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/hall/Hall1.jpg
09:10 PM Tom_L: had to slot the ring without breaking it
09:15 PM pink_vampire: Tom_L: this is look like something that i would do ! cool!!
09:16 PM pink_vampire: Tom_L: what this thing do?
09:17 PM skunkworks: Tom_L: cool - just need a way to get that back into linuxcnc ;)
09:17 PM Tom_L: that was a while back. not even sure where it is now
09:18 PM Tom_L: i did get a power meter from china though, just need to hook it up
09:18 PM pink_vampire: for dc?
09:18 PM Tom_L: yup

09:27 PM net|: the ebay age
09:30 PM net|: so friendly old people even know how to use it
09:31 PM Tom_L: of course... they're the ones with the money
09:57 PM net|: not really, alot of baby boomers are bust
09:57 PM net|: not even enough money for retirement
