01:28 AM roycroft: well, setting up dual boot and installing linux mint on this old imac alongside os x was trivial
01:58 AM drdoc: roycroft: how you like it?
02:28 AM miss0r: goodmorning
02:33 AM drdoc: hola
02:52 AM miss0r: Just got back from the o-ring pusher... why is it they always have a +1 and a -1 but never the exact size you need? :S
03:03 AM miss0r: meh.. the smaller size was just perfect for this pneumatic cylinder. it is now air tight again
03:11 AM drdoc: that's luck
03:16 AM miss0r: yup
03:17 AM miss0r: but client will be pleased, as now I can go reinstall it tomorrow instead of them having to wait 4 weeks for a replacement cylinder from the machine builder :)
03:17 AM drdoc: heh
03:17 AM miss0r: drdoc; what do you do for a living, since you can be in here floating around at this hour? :)
03:17 AM drdoc: that kind of rep is priceless
03:18 AM drdoc: I don't, right now
03:18 AM drdoc: between jobs
03:18 AM miss0r: Meaning; lots of time to fiddle around with linuxcnc? :)
03:19 AM drdoc: I quit doing unix admin to go to school & learn CAD/CAM, did that for a year, and got edged out of the job a few months back
03:19 AM drdoc: lots of time to do squat
03:20 AM miss0r: s/squat/improve skills
03:20 AM drdoc: this is the first time in my life there hasn't been work right around the corner
03:20 AM miss0r: I have a side buisness doing unix admin stuff. You can have it :D I'm sick of it
03:21 AM drdoc: yeah, I got spoiled working in the machine shop - I had free run of the machines after hours
03:22 AM miss0r: I never had that option. I had to make my own shop to have use of machine tools
03:22 AM drdoc: I did linux, AIX, HP/UX, and a bit of Solaris from '95 till 2015
03:22 AM Loetmichel: hmpf... i think my 800W china cnc milling spindle is on its way out... bearings dont sound tooo goood and i had "overload" on the (1.5kW!)VFD while spinning up for the third time this week...
03:22 AM drdoc: it was a dream job - small shop, big mills, small crew, and mostly prototype work
03:23 AM miss0r: that sounds realy nice
03:23 AM miss0r: Loetmichel: sure sounds like it
03:23 AM drdoc: I got to do design for Samsung, AMD, and a coupleof other semi-conductor plants here
03:23 AM miss0r: drdoc: I used to be a slackware freak, back in the '90s. I've since "seen the light" and am now a full on debian guy
03:23 AM Loetmichel: ... may have to do with the fact that it spins up in 1 sec to 24kRPM though
03:23 AM miss0r: Loetmichel... yeah
03:24 AM drdoc: miss0r: slack was my first linux
03:24 AM drdoc: 54 floppy disks
03:24 AM miss0r: the first one I ever installed was corel.. didn't like it & installed slackware :D
03:24 AM Loetmichel: still i didnt change the parameters on the VFD for the last 6 years, and it just started doing overloads now
03:24 AM miss0r: damn... I remember installing windows 95 from floppies.. exactly 54 :D
03:24 AM drdoc: heh, I remember corel
03:24 AM miss0r: I can't remember slackware
03:24 AM Loetmichel: so i think the bearings have more drag now
03:24 AM miss0r: (amount of disks anyway)
03:25 AM drdoc: about 2 months later I found out about the repo CD sets
03:25 AM miss0r: Loetmichel: If they even sound funny... 6 years you say? on a 24k rpm chinesium spindle?
03:25 AM Loetmichel: miss0r: i still have an "original" suse 6.4 on 1,44mb disks.. :-)
03:25 AM drdoc: and damned if I can remember the name
03:25 AM Loetmichel: miss0r: yes
03:25 AM Loetmichel: 7 years now
03:25 AM drdoc: walnut creek
03:25 AM Loetmichel: and 5 days a week about 4 hours usage at the company
03:25 AM miss0r: Loetmichel: That is a damn miracle. Just go ahead and replace it and be very happy it lasted so long
03:26 AM Loetmichel: quite good for chinesium if you ask me ;)
03:26 AM drdoc: Loetmichel: I think I still have a copy of Yggdrasil
03:26 AM miss0r: drdoc: The stuff you sometimes remember
03:26 AM drdoc: yeah
03:27 AM * miss0r is just standing around now waiting for the mailman do drop off two cylinder seals, so I can get the h... out of here to install some refurbished gear at a client
03:27 AM Loetmichel: drdoc: was quite the package: ah, no picture of the disk box. only the CD versions... -> http://www.cyrom.org/palbum/main.php?g2_itemId=13853
03:27 AM Loetmichel: but the disk box was about as big as the 9.1 in the back
03:28 AM drdoc: yup
03:28 AM drdoc: I had 6.2 for powerpc
03:28 AM Loetmichel: IMHO 7.3 was the last good one from suse
03:28 AM drdoc: heh, yes
03:28 AM Loetmichel: but i digress ;)
03:28 AM miss0r: I did a cute little repair last night. an APC(Automatic pallet changer) for a mazak cnc mill. it has a 20mm pin that runs up and down in a bushing, locking the pallet from rotation at 4 positions 90degrees apart. The bushing was looking like it was grease(so deformed) and the 20mm pin was snapped... it took some work
03:28 AM drdoc: Novell actually did a good job with them
03:29 AM miss0r: ahh.. one thing I am sad I never got to play around with: a sun workstation.
03:29 AM drdoc: you didn't miss much
03:29 AM miss0r: like an old ultrasparc or something
03:29 AM drdoc: Sun had the worst management tools ever
03:30 AM miss0r: I dunno... theres always just been something about them that I found appealing(without ever having had hands on experience)
03:30 AM drdoc: all Java based, all slow as molasses, and no two alike
03:30 AM miss0r: lol.. sounds like something right up my alley.. I drive a '72 land rover some simular reasons :D
03:30 AM drdoc: even at the commandline, there's no convention to the tools' options and arguments
03:30 AM * Loetmichel is always looking for a cheap indy pizzabox
03:30 AM Loetmichel: always wanted to have one
03:31 AM drdoc: Shoulda met me 18 months ago
03:31 AM drdoc: I gave away a pallet of Indys
03:31 AM miss0r: :o
03:32 AM drdoc: I'd been storing them for 10 years, couldn't get anybody to pay for them
03:32 AM miss0r: I love classic IT hardware :D
03:32 AM drdoc: there are 2 NeXT Turbo Slabs and a Cube in my garage
03:32 AM drdoc: and a couple of PDP-11s
03:32 AM drdoc: :-)
03:33 AM miss0r: I mean; I have one of those "transportable" PCs.. where they keyboard is clipped to the front of the box, and the albeit color monitor flat screen sorta "pop" up and at an angle :)
03:33 AM drdoc: dolch?
03:33 AM miss0r: I bring it into the living room once in a while to kick my wifes ass in classic arcade games
03:33 AM drdoc: heh
03:33 AM miss0r: that doesn't ring a bell
03:34 AM drdoc: color screen?
03:34 AM miss0r: yeah. it looks like the real classic. even has a simular same
03:34 AM drdoc: Dolch was the best-known luggable, but Compaq, HP, and a few others made them
03:35 AM miss0r: "portable pc III"
03:35 AM drdoc: Compaq, then
03:35 AM miss0r: but this is one bought as a kit at some point -
03:35 AM drdoc: ah
03:35 AM miss0r: it has a K6 socket motherboard ect
03:35 AM miss0r: it came with a special graphics card that could handle the screen
03:36 AM miss0r: but the keyboard is the round DIN plug... :)
03:36 AM drdoc: I think my favorite toy right now is a 486 color laptop
03:36 AM miss0r: I get that :D
03:37 AM miss0r: I did the best of my gaming on a 486-66 DX(if I recall correctly). it ran duke nukem 3D like a charm.
03:37 AM Loetmichel: miss0r: like this? -> http://www.cyrom.org/palbum/main.php?g2_itemId=4591&g2_imageViewsIndex=1
03:37 AM miss0r: Loetmichel: close: google "portable PC III"
03:37 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=4403&g2_imageViewsIndex=1 <- left corner
03:37 AM drdoc: https://imgur.com/gallery/jPan5
03:38 AM drdoc: https://imgur.com/gallery/5PBWf
03:38 AM miss0r: how did that repair hold up? those hinges are ridiculously stressfull for the plastic at the mounts
03:44 AM drdoc: it's great
03:44 AM drdoc: JB Weld is ridiculously strong if you treat it right
03:44 AM miss0r: that is true
03:44 AM miss0r: I have a compaq armada in the basement
03:44 AM drdoc: I used it insted of Bondo on my motorcycle's tanks
03:44 AM miss0r: It only ever comes out to emulate a tape station for the commodore 64 :D
03:44 AM drdoc: heh
03:44 AM drdoc: Uh
03:44 AM drdoc: you want a Commodore tape deck?
03:44 AM miss0r: I have one. I just don't have any tapes :)
03:44 AM drdoc: ah
03:44 AM miss0r: I actualy have two...
03:44 AM Loetmichel: drdoc: hehe, yes, the old stuff is indestructible... recently found a chicony 486 on my scrapheap, broken off display, missing covers, dead batters... powered it externally: http://www.cyrom.org/palbum/main.php?g2_itemId=16238&g2_imageViewsIndex=1
03:44 AM miss0r: but in all fairness. It does not see alot of use
03:44 AM drdoc: Loetmichel: got the keyboard?
03:44 AM Loetmichel: drdoc: as you can see on the pic: it still had the keyboard
03:44 AM Loetmichel: or what did you mean?
03:44 AM miss0r: Loetmichel: I used to have a IBM thinkpad I was handed because my uncle managed(don't ask me how) to back it over with his car. The screen was done for, but I made a bracket and mounted it in a 19" rack & ran it as a webserver for years
03:45 AM drdoc: I used them at work for too long - teaching AIX admin courses for IBM
03:46 AM miss0r: why would anyone want to spend money on those?
03:46 AM drdoc: the old RISC workstations used Model M-alikes
03:46 AM drdoc: because they're in style
03:47 AM miss0r: hah...
03:47 AM drdoc: I prefer Cherry-type keyboards
03:47 AM miss0r: Axle seals just got dropped off. See you around
03:47 AM drdoc: I'm converting an old Link-branded Wyse keyboard now
03:47 AM drdoc: https://imgur.com/gallery/ArIVUxl
03:47 AM drdoc: later
03:49 AM drdoc: You'd think that when you build a .deb package of a freshly-built kernel, dpkg would take the binaries and pak 'em up
03:49 AM drdoc: but noooooo
03:49 AM drdoc: clean it out and do the whole dang compile again
03:53 AM Loetmichel: drdoc: i know... i have four Model M
03:54 AM Loetmichel: and apart from the one i got from my father 25 years back they were all above 40 eur on ebay
03:54 AM drdoc: I have a WheelWriter I'm thinking about separating
03:55 AM drdoc: I could use a dot-matrix printer, and the keyboard's buckling-spring
04:26 AM Loetmichel: drdoc: we still sell Epson LQ 300+... new ;)
04:26 AM Loetmichel: but a bit modified ;)
04:26 AM Loetmichel: http://cordsen.com/index.php/rugged/printer/59-rugged/bw-printer-rugged/147-cp-8240n
04:26 AM Loetmichel: ... "a bit" :-)
04:27 AM Loetmichel: ... and you DONT want to know the price .-)
05:02 AM jthornton: morning
05:03 AM XXCoder: yo
05:10 AM Loetmichel: hmmm... i have my machine running under Linux CNC6040 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 GNU/Linux ....
05:10 AM Loetmichel: any idea how to upgrade to something thats still supportet without destroying the CNC config??
05:11 AM XXCoder: its not martin so maybe config is more... portable?
05:11 AM Loetmichel: martin?
05:11 AM XXCoder: oh reprap firmware. tends to change configuration a lot so updates breaks it
05:11 AM drdoc: Loetmichel: marlin
05:11 AM Loetmichel: problem is: last time i tried to upgrade it destroyed the linuxCNC system
05:12 AM drdoc: look for a .something file or directory
05:12 AM Loetmichel: lots of step loss
05:12 AM drdoc: .linuxcncrc or something
05:12 AM Loetmichel: and not because of the config itself but beacuse linuxcnc had a bug ;)
05:12 AM drdoc: ah
05:13 AM drdoc: not much direct defense against that
05:13 AM drdoc: image your drive before you upgrade
05:13 AM XXCoder: you could yeah there ya go
05:13 AM drdoc: heh
05:13 AM XXCoder: or just install new one on seperate drive
05:13 AM drdoc: or that
05:14 AM drdoc: ok
05:14 AM drdoc: it's about 8 hours past my bedtime
05:16 AM drdoc: kernel packages built, RTAI packages built
05:16 AM drdoc: linuxcnc packages can wait till I've napped
05:16 AM drdoc: later, gents
05:18 AM XXCoder: later
06:41 AM janmar is now known as JanMrlth
06:44 AM XXCoder: https://www.youtube.com/watch?v=C4qGxFDJPi4 pretty cool. make knife by cmc
06:44 AM miss0r: job complete :)
06:45 AM miss0r: XXCoder: Carbide knife? :S
06:45 AM XXCoder: yeah
06:45 AM XXCoder: maybe bit brittle but damn strong
06:46 AM miss0r: sounds awesome
06:49 AM miss0r: but that is not carbide.. he is using O2 tool steel
06:49 AM XXCoder: yeah
06:49 AM XXCoder: i dont know that metal lol
06:50 AM miss0r: its a cool material
06:50 AM miss0r: I use it often :D
06:50 AM XXCoder: all tools at work is carbide
06:51 AM XXCoder: i dont think we ever cut carbide either
06:51 AM XXCoder: though we also run inecel which is extra fun
06:51 AM miss0r: :D
06:53 AM XXCoder: wonder if my machine can do it lol
06:53 AM XXCoder: his machine seems light duty
06:53 AM XXCoder: but not el cheapo like mine
06:54 AM miss0r: hmm... Its all a question of feeds'n speeds
06:54 AM miss0r: and if you have time enough
06:56 AM miss0r: I've wanted to make knifes for a while :) I might just go ahead soon
06:57 AM XXCoder: could do fake ones out of alum
06:57 AM XXCoder: display only
06:57 AM XXCoder: and backup murder weapon lol
06:57 AM XXCoder: jk
06:57 AM miss0r: and melt them after the fact.. there can be no murder if theres no murder weapon
06:57 AM miss0r: :P
06:58 AM XXCoder: oh just mill it into smaller knife
06:58 AM miss0r: Reminds me of a story where someone killed someone with a frosen salmon, and ate it afterwards
06:58 AM miss0r: I was going to make a glorious kitchen knife (I love cooking)
06:58 AM XXCoder: nice
06:59 AM miss0r: and that would be a nice addition to the "tool rack" of the kitchen
06:59 AM miss0r: and it would have to be crazy sharp. bodyguard katana sharp :P
07:00 AM XXCoder: one I would make would envy butter knife's sharpness
07:00 AM miss0r: https://www.youtube.com/watch?v=axS2H5cYfUg 2:40
07:02 AM XXCoder: heh corwin's time machine book they invented a knife where any atom touch it would be transported away
07:02 AM XXCoder: essentally infinitely sharp knife
07:02 AM XXCoder: it cuts in any direction, include sideways
07:02 AM miss0r: :D nice
07:02 AM XXCoder: negative is its noisy
07:02 AM XXCoder: due to it sucking in air
07:03 AM miss0r: yeah... that thing is dangerous :D
07:05 AM miss0r: you couldn't even keep it suspended in a box... well, you could, but you would be unable to open it, due to the vacuum created
07:05 AM XXCoder: thankfully it can be turned off
07:05 AM XXCoder: requires all 5 fingers to press on its switch
07:05 AM XXCoder: guess why
07:05 AM XXCoder: 5 switches that is
07:06 AM miss0r: makes sense
07:06 AM miss0r: you wouldn't want to have it suck in your fingers :D
07:06 AM XXCoder: from story it dont seem to have that strong of a suck force
07:06 AM XXCoder: but it goes though with zero effort
07:07 AM XXCoder: oh yeah they was also machinists. they finally said "oh duh we can make tools with this"
07:07 AM XXCoder: infinite life endmill for one
07:07 AM XXCoder: rpm, as high as you can go without it vibrating
07:08 AM XXCoder: same for ipm, theres no limit on that besides machine limit
07:08 AM XXCoder: well maybe limited by rpm also, if too fast you might have "bumps" on cutting side
07:09 AM XXCoder: ie not perfectly flat
07:10 AM miss0r: now that sounds interresting
07:10 AM miss0r: especially not having to clear chips
07:10 AM XXCoder: yeah it would get dusty later as atoms returns to around the area after few seconds. never was serious problem apparently
07:12 AM miss0r: hmm.. A model where the atoms are teleported to the center of the earth. that would be nice
07:13 AM XXCoder: yeah that was early version, later ones they simply sent it off to hyperspace and left it there
08:53 AM R2E4: hello all
08:54 AM R2E4: JT-Shop you there?
08:54 AM JT-Shop: yo
08:54 AM R2E4: I checked your site and 7io84 are out of stock
08:54 AM R2E4: You getting some soon?
08:56 AM R2E4: plus you only have 1 thcad?
08:56 AM R2E4: I would like to order 3
08:57 AM JT-Shop: for a little bit
08:58 AM JT-Shop: yes, I'll be placing a stock order this week, how many do you need?
08:58 AM R2E4: I need 2 7i84 and 3 thcad
08:59 AM JT-Shop: thcad-10?
08:59 AM R2E4: everything else you have. for two machines
09:42 AM T_F_Skywalker: So I notice a few folks use PC based cooling stuff for their liquid cooled spindles... A good setup looks to be about $250-300 and is only designed to disapate about 200W. What would be wrong with using a Tig Cooler? I can get a "decent" chiller for <$200 and it will move ~1.5kW and seems like it would be a bit more robust.
10:38 AM syyl: i have a cheap aquarium pump and a rubbermaid box with 10 liters volume
10:38 AM syyl: i think that setup was less than 40eur
10:38 AM syyl: cooling a 2,2kW spindle
10:41 AM syyl: i monitored it over a few hours and couldnt measure any temperatur rise more than a few °C
10:41 AM syyl: but i didnt run it at 2,2kW load ;)
10:45 AM gregcnc: must be an important drill press https://www.ebay.com/itm/303175769074?
10:49 AM methods_: oh wow that price is serious lol
11:00 AM jthornton: does it come with the house?
11:04 AM T_F_Skywalker: @syyl, seems like a better solution. I doubt most jobs I'd run would last long enough to thermal soak 10L.
11:25 AM SpeedEvil: https://i.imgur.com/l3AivvC.jpg :)
11:57 AM tommylight: evening
11:58 AM JT-Shop: yo
11:59 AM tommylight: yo JT, sup ?
12:01 PM JT-Shop: trying to find my desk...
12:08 PM tommylight: LOL, did it move or ?
12:08 PM JT-Shop: it's covered up lol
12:08 PM JT-Shop: I'm sure it's under this pile of paperwork somewhere
12:08 PM tommylight: oh cr@p
12:08 PM tommylight: =D
12:09 PM JT-Shop: I had to revert all the reconciles back to june, kept getting them fouled up with transfers lol
01:51 PM drdoc: holy crap
01:51 PM drdoc: the dependency list for building linuxcnc is *nuts*
02:01 PM drdoc: why do I need Apache installed to run a mill????
02:05 PM Tom_L: you don't unless you want to go on the ninnernet with the mill
02:06 PM gregcnc: what are you going to do during cycles? be productive?
02:06 PM Tom_L: you can only debur so much before it's out of tolerance
02:07 PM SpeedEvil: Or round.
02:07 PM SpeedEvil: ^spherical
02:10 PM syyl: lol
02:10 PM syyl: cycletime is gold ;)
02:12 PM gregcnc: syyl i just watched the lathe churn for an hour on of 609.6mm of Ø25.4m bar ;)
02:12 PM gregcnc: mm
02:12 PM syyl: haha
02:12 PM syyl: there is always something else to do ;)
02:14 PM gregcnc: I have to figure out how to make sure things don't go bad at the end of a bar. Right now the prg calculates how many parts and stops. only 2 more could be made so that is safe
02:16 PM gregcnc: but it still needs proving. I should set the drawbar monitor and have it err on overtravel
02:16 PM gregcnc: but I'm not quite sure how to avoid clamping on say 1mm and pulling out while running
02:18 PM drdoc: Tom_L: running a dependency check on the linuxcnc package build got me over 100 new dependencies
02:19 PM drdoc: including not only Apache, but all of the development packages for Apache
02:50 PM Tom_L: get a bigger hdd?
02:51 PM Tom_L: it is getting a bit bloated i agree
02:51 PM drdoc: I'm not concerned about disk space
02:51 PM drdoc: it's just sloppy
02:54 PM JT-Shop: I've never had any where close to that many packages and never apache
02:54 PM * JT-Shop thinks something is wrong...
02:56 PM JT-Shop: 36 dependencies for linux mint 19 and 1/2 are for the pdf document I think
02:56 PM XXCoder: why do linuxcnc need apache dev stuff?
02:58 PM drdoc: JT-Shop: running dpkg-checkbuilddeps in the linuxcnc repo throws a list of dependencies whose sub-deps include apache
02:59 PM drdoc: IOW satisfying the dependencies for the linuxcnc dependencies includes installing Apache
02:59 PM JT-Shop: I've installed LinuxCNC a 100 times and never had to install apache, what do you mean exactly by linuxcnc repo?
03:00 PM drdoc: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Building_RTAI_5.2_Packages
03:00 PM drdoc: I'm not installing, I'm *building* .deb packages
03:01 PM JT-Shop: yea that's what I do as well but I build linuxcnc uspace
03:01 PM drdoc: it's moot at this point, though - patching the linuxcnc repo hangs indefinitely
03:02 PM JT-Shop: and that's RTAI, which I don't use anymore
03:02 PM drdoc: I haven't gotten as far as configure
03:03 PM JT-Shop: Andy is usually around this time of day but I see he out right now or you could ask him, that's his page
03:04 PM drdoc: ok
03:10 PM jthornton: so your down to the next to last line?
03:10 PM jthornton: dpkg-checkbuilddeps
03:13 PM drdoc: yes
03:13 PM drdoc: after ditching the patch
03:14 PM drdoc: it hangs without changing anything
03:14 PM jthornton: oh you skipped parts?
03:15 PM drdoc: I couldn't find the error in the patch file, so I used "configure --with-realtime=uspace"
03:16 PM jthornton: you can't use uspace with rtai only rt preempt
03:16 PM drdoc: which according to README.md, should build against the installed RTAI kernel & modules
03:16 PM jthornton: ok
03:17 PM jthornton: why rtai and uspace?
03:17 PM jthornton: parallel port stepper?
03:17 PM drdoc: yup
03:17 PM drdoc: this is a very shoestring project
03:18 PM jthornton: well you can't skip and steps in Andy's guide...
03:18 PM jthornton: and > any
03:18 PM jthornton: anyhow back to work for me
03:28 PM SpeedEvil is now known as Guest63641
03:31 PM jym: howdy y'all
03:32 PM JT-Shop: yo
03:33 PM jym: Had a kitty cat and cub playing in the backyard last night
03:33 PM jym: ...and by kitty kat, I mean Mnt Lion and cub
03:34 PM JT-Shop: getting kinda close?
03:35 PM jym: The back neighbor has goats and horses, so I figure they just hopped the fence to go whereever they go
03:35 PM jym: They didn't really play, just passed thru
03:36 PM jym: I'm just glad I have motion lights, and they tend to avoid lighted areas
03:36 PM JT-Shop: we have some feral dog packs that have killed goats twice and cats, dogs, ducks, chickens
03:37 PM jym: Do YOU have motion lights? just curious
03:38 PM JT-Shop: yea
03:38 PM jym: Ah, so they aren't efective at keeping them away, good to know.
03:38 PM jym: They are for MntLion's though, for the most part.
03:38 PM JT-Shop: they killed my cat at noon...
03:39 PM jym: Oh geeze, sorry to hear that.
03:40 PM jym: I've been thinking about fly paper or eve motion activated water sprayers
03:40 PM JT-Shop: I'll pay them back...
03:42 PM jym: .22lr trip wire?
03:43 PM JT-Shop: 12 gauge...
03:44 PM JT-Shop: guy with the goats has killed 10-12 of them so far, but that is a different bunch from the ones I'm hunting
03:45 PM jym: Damn, that's a lot
03:45 PM jym: Poisoned food?
03:45 PM jym: thugh might get other critters too
03:46 PM JT-Shop: there ain't no other critters around any more, just dogs
03:48 PM XXCoder: im curious if you noticed that theres much fewer bird now
03:48 PM XXCoder: I read article that thers 25% to 90% exinaction each bird species now :(
03:50 PM JT-Shop: not around here, I put out the same amount of food for them every day
04:00 PM Deejay: gn8
04:03 PM jym: JT-Shop Just a thought... https://www.youtube.com/watch?v=leBv8XUE_oo
04:04 PM jym: 32 minutes
04:05 PM JT-Shop: way too long to watch this early in the month, yesterday I had a ton of usage left
04:05 PM jym: uses .22 nail gun blanks as trip wires
04:06 PM jym: JT-Shop Of course, murphys law, https://www.amazon.com/MULTICAM-Property-Perimeter-Mini-Sentry-Paintball/dp/B00VVUCF6A
04:06 PM jym: you could make a few of those easily
04:07 PM jym: iirc they say NOT to use fishing line as it stretched, But I find some no stretch braided line too
04:10 PM JT-Shop: about the only way in and out of this property is through my gate or my neighbors gate or over the fence
04:11 PM jym: Is that how they have been getting in so far?
04:12 PM JT-Shop: I guess, I have a gate alarm but I can't always be in here to hear it anyway nothing left here for them to kill
04:12 PM jym: are your chickens okey?
04:13 PM JT-Shop: chickens live in Chicken Fort Knox
04:13 PM jym: k
04:13 PM JT-Shop: 5' chain link fence with 3 hot wires around the outside and a gun toting old fart
04:14 PM jym: Well, maybe it'll scare the fuck out of them ? future preventative measures?
04:15 PM jym: .22lr nail gun blanks wouldn't be a felony, so you could make and even sell a few as I'm sure others are having the same issue.
04:18 PM JT-Shop: county police told us if you get one in your sights kill it
04:18 PM jym: good,
04:18 PM jym: I just wouldn't want to kill other things is all
04:21 PM JT-Shop: damn I found my desk...
04:21 PM jym: Did it walk away and got homesick?
04:22 PM JT-Shop: covered up in paperwork and crap lol
04:22 PM jym: Noting 2 gallons of gasoline and a road flare wouldn't reoslve
04:27 PM jym: JT-Shop FWIW.... .22 fits 1/8" black pipe, and .12ga fits 3/4" black pipe, just sayin =)
04:29 PM jym: Hmmm, I wonder if 410 will fit 1/2" black pipe?
05:09 PM BitEvil is now known as SpeedEvil
05:17 PM * JT-Shop is not looking for a Darwin award...
05:20 PM _unreal_: drdoc, yes RT on tinkerboard
07:26 PM _unreal_: good lord carbide create crashes easy
07:31 PM _unreal_: I am SOO damn smart :)
07:31 PM _unreal_: I didnt save a file I should have a cad drawing
07:31 PM _unreal_: or I over wrote it
07:31 PM _unreal_: I do HAVE an ESTLcam file of it
07:32 PM _unreal_: but I cant edit the cad drawing
07:32 PM _unreal_: and the only EDIT is shifting everyting 2mm :)
07:32 PM _unreal_: WELL SHIT I can just re-offset my machines location and go from there
07:32 PM _unreal_: :)
07:32 PM _unreal_: same damn thing
07:34 PM roycroft: i've yet to find a decent version control mechanism for cad drawings that doesn't cost thousands of dollars
07:35 PM roycroft: currently i'm using git, and that works, but it's a stupid and wasteful way to do it
07:39 PM _unreal_: huh?
07:39 PM _unreal_: I'm not sure I follow you'
07:40 PM _unreal_: heh this fixture is soo freaking tight I have to fiddle with it several times and then tap it in
07:42 PM _unreal_: gid as in git clone?
07:42 PM roycroft: you mentioned overwriting a cad file
07:42 PM roycroft: using version control lets you recover the older version
07:42 PM _unreal_: oh OHHHH oh ok thats what you mean
07:42 PM _unreal_: version control
07:42 PM _unreal_: ya...
07:43 PM _unreal_: thats one of those sticky slopes
07:43 PM _unreal_: some times you want non stop version maintaining and other times. it does not matter no way no how if its over writeten
07:43 PM _unreal_: especially when it comes to cad drawings
07:44 PM roycroft: the one thing that makes git really good for cad drawings is how it is designed to be able to fork and merge branches so easily
07:44 PM _unreal_: roycroft, I cant tell you how OVERLY impressed I am with these bits https://www.amazon.com/gp/product/B078S3S956/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
07:44 PM roycroft: i'll do a rough drawing or set of drawings, do a commit
07:44 PM _unreal_: These are good as well but I use the first link 10x more https://www.amazon.com/gp/product/B078MJCZFK/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
07:44 PM roycroft: if i want to play with a variant i'll fork off a sandbox branch
07:45 PM roycroft: if i like the results i'll merge it back in
07:45 PM _unreal_: humn
07:45 PM roycroft: or toss if if not
07:45 PM roycroft: the big problem with git is that it does not understand .dwg or .stl or similar file formats
07:45 PM roycroft: so its granularity is at the file level for cad stuff
07:45 PM roycroft: "that file has changed"
07:45 PM roycroft: instead of
07:45 PM roycroft: "that feature has changed"
07:46 PM roycroft: i rarely use upcut tooling for the stuff i do
07:47 PM roycroft: but i don't do cnc cutting at the moment
07:48 PM _unreal_: these blades do not leave much in the way of ruff frills
07:48 PM _unreal_: on the top level of the material
07:48 PM _unreal_: tey do chatter a little but almost nothing
07:48 PM _unreal_: and they are SOO strong
08:23 PM CaptTactful: hey out there!
08:24 PM CaptTactful: Im running 2.7 Wheezy lcnc and am having home issues with my z axis. anybody wanna take a shot with help?
08:25 PM CaptTactful: its a fresh install and my old step config is nowhere to be found so im winging it.
09:17 PM drdoc: _unreal_: speak to me of this LCNC on Tinkerboard
09:18 PM * drdoc haz one
09:35 PM norias: hello
09:40 PM CaptTactful: heya
09:42 PM andypugh: There are some forum posts about LinuxCNC on the Tinkerboard.
09:43 PM CaptTactful: would anyone be willing to help me refine my stepconfig please?
09:44 PM CaptTactful: im trying to add i9n my homing switches
09:45 PM norias: oh, while i'm here
09:45 PM norias: any thoughts on spindle speed feedback in linuxcnc?
09:45 PM CaptTactful: thx
09:45 PM drdoc: andypugh: I'm reading them now
09:51 PM drdoc: I presume it would need external motion control hardware?
09:54 PM norias: drdoc: you mean for spindle speed feedback?
09:55 PM drdoc: norias: really I meant "I presume that the TB isn't fast enough for software step generation"
09:55 PM norias: oh, ok
10:19 PM _unreal_: hi
10:19 PM _unreal_: drdoc,
10:20 PM _unreal_: drdoc, first off https://www.armbian.com/tinkerboard/
10:21 PM _unreal_: drdoc, https://forum.armbian.com/topic/10007-tinker-board-current-rtos-working-free-offer/
10:22 PM drdoc: _unreal_: reading the forum thread now
10:22 PM _unreal_: its my post
10:24 PM drdoc: ah, cool. Mine's running LibreElec at the moment, but that - streaming TV - is literally the only thing it doesn't do better than a Raspberry Pi
10:25 PM _unreal_: realy?
10:25 PM _unreal_: drdoc, if you follow some of my post's I talk about how to get that fixed
10:25 PM _unreal_: drdoc, https://github.com/berinc/Asus-Tinker-Board
10:25 PM _unreal_: that will link you to a lot of info
10:25 PM _unreal_: and howto's
10:25 PM _unreal_: but based on armbian
10:26 PM _unreal_: from that link #4 you may find interesting
10:29 PM _unreal_: ?
10:31 PM drdoc: yeah, the Pi has better graphics
10:31 PM drdoc: Babe's home, I'll be back later
10:31 PM drdoc: thanks for the links
10:31 PM _unreal_: according to the specs the tinkerboard has a better GPU
10:32 PM drdoc: LibreElec, OSMC and the like don't support it as well as the Pi
10:33 PM drdoc: oddly, the best gfx performance I've gotten with it was in Android
10:33 PM drdoc: anyhow, I need to pay attention to the lady for a while
10:33 PM drdoc: later!
10:55 PM Elmo40: hardware any better on the TB vs RasPi?
10:56 PM Elmo40: or has the R4 one-up'd it?
11:29 PM drdoc: Elmo40: The TB has one thing over the RP4 - 802.11 antenna connectors
11:30 PM drdoc: other than that, I couldn't say. I haven't paid a lot of attention
11:34 PM Elmo40: but are either of them worth running LCNC on ?
11:34 PM drdoc: that's what I'm looking at
11:37 PM drdoc: my guess would be "no", at least not if you need software stepping
11:37 PM drdoc: but it would be a total guess
11:44 PM andypugh: drdoc: Maybe not, depending on the step rates needed.
11:50 PM drdoc: andypugh: the current machine is running 1.5A steppers, so... step rates are probably not going to be crazy high, no matter what the controller looks like
11:50 PM _unreal_: drdoc, I've already proven the tinkerboard could be a software stepper
11:51 PM _unreal_: the issue is getting a GPIO HAL driver written
11:51 PM _unreal_: I CANT I dont know how to code at that level and not by a long shot
11:51 PM drdoc: yeah, me either. I'm a systems guy, not a coder
11:51 PM _unreal_: that project is totally stalled at this point and if not indefinite. I have had a SHIT load of peple offer to help and then just disapeared off the face of the earth
11:52 PM drdoc: that's kind of normal
11:52 PM drdoc: unfortunately
11:52 PM _unreal_: On top of that work gave me a PC they broke
11:52 PM _unreal_: 23" I5 TOUCH SCREEN. broken touch screen
11:52 PM drdoc: ah, yeah
11:53 PM _unreal_: So I'm going to get a USB touch screen overlay and make a small shell for it
11:53 PM drdoc: some guy gave me a touch screen laptop Sunday
11:53 PM drdoc: proved something I always suspected
11:54 PM _unreal_: which is?
11:54 PM drdoc: if there's a real keyboard, I don't need to get the display dirty
11:54 PM drdoc: it was fun for about 8 minutes
11:54 PM _unreal_: touch displays are helpful when doing machining
11:55 PM drdoc: for a control head, where there isn't really room for a keyboard, of course
11:55 PM Wolf__: hotkeys>touchscreen
11:55 PM _unreal_: its much faster to display control then fumbel for the mouse. when your in a race
11:56 PM _unreal_: !@#%@#$^!@#$ 1am already
11:56 PM _unreal_: I freaking passed out for 2 hours
11:56 PM drdoc: I was at the local goodwill this evening; they had 3 or 4 Intuos graphics tablets
11:56 PM drdoc: $10, no stylus or puck
11:56 PM _unreal_: intuos ?
11:57 PM drdoc: Wacom gfx tablet
11:57 PM _unreal_: OH
11:57 PM _unreal_: I was thinking tablet computer not drawing tablet
11:57 PM drdoc: ah, no
11:58 PM drdoc: I was mightily tempted
11:58 PM _unreal_: those wacom's are like $80 + as I recall
11:58 PM _unreal_: and the stylet are cheap to replay "amazon"
11:58 PM _unreal_: styless
11:58 PM _unreal_: OMG I'm tired
11:59 PM _unreal_: and the styless are cheap to replace "amazon"
11:59 PM drdoc: yeah
11:59 PM drdoc: I wanted to check the resolution & price of replacements
