01:28 AM XXCoder: hm extreme snow warning for jan 9-12
01:40 AM XXCoder: tacoma weather dont show any snow as prediction so dunno lol
01:40 AM XXCoder: not that it really affects me either way
01:59 AM Deejay: moin
04:42 AM Tom_L: morning
04:42 AM Tom_L: 25 / 45
05:25 AM JT-Cave1: morning
06:12 AM travis_farmer: Morning
06:15 AM Deejay: good afternoon ;)
07:10 AM JT-Cave1: 34/45
07:35 AM travis_farmer: 15F/19F and snowing
08:41 AM NoSpark: I'm having massive latency spike caused by the nouveau driver. Any advice?
08:42 AM lcnc-relay: <zincboy_ca_on> Don't use the nouveau driver?
08:43 AM NoSpark: lcnc-relay: I always thought you were a bot :P
08:43 AM NoSpark: ok, is the radeon driver better?
08:43 AM NoSpark: lcnc-relay: good bot
08:44 AM lcnc-relay: <zincboy_ca_on> Not a bot 😛 Just a link to discord.
08:45 AM lcnc-relay: <zincboy_ca_on> I tend to just use whatever the default kernel driver is. It is not like you need high performance video or 3d for linuxcnc.
08:45 AM NoSpark: send me a discord invite?
08:45 AM NoSpark: true
08:46 AM lcnc-relay: <zincboy_ca_on> https://discord.gg/SbskPKPJc6
08:57 AM Unterhaus_ is now known as Unterhausen
09:04 AM Tom_L: JT-Cave1, PR#62 up
09:07 AM lcnc-relay: <satiowadahc#0> Better option don't use a dedicated GPU and skip both nouveau and proprietary drivers.
09:09 AM lcnc-relay: <jackrabbitjury> I agree, but I have a PCI (not PCIe) card I need to use, and I also require hdmi
09:13 AM Tom_L: JT-Cave1, encoder feedback & scale still don't get saved in the ini
09:13 AM Tom_L: in the spindle section
09:13 AM Tom_L: i forgot if we already talked about that
09:16 AM JT-Cave1 is now known as JT-Cave
09:16 AM JT-Cave: working on the spindle now
09:21 AM JT-Cave: a few things will likely break if you try and update... I'll be releasing 2.1.0 soon
09:27 AM Tom_L: ok
09:28 AM Tom_L: i'll wait for 2.1.0 and your ok
09:43 AM JT-Cave: ok
09:55 AM Tom_L: wonder if i dare update lcnc on the rpi
09:59 AM Tom_L: naw, there's no deb for it just a full install .gz
10:03 AM Tom_L: what is a .dsc file?
10:12 AM JT-Cave: dunno
10:12 AM JT-Cave: today
10:12 AM JT-Cave: 's challenge is to figure out how to set a minimum spindle speed
10:12 AM Roguish: fricking cold here. was down to 29, now all the way up to 32
10:12 AM Tom_L: we've got some sub 20 weather coming
10:12 AM Roguish: JT-Cave, give it an arbitrary 1000rpm
10:13 AM JT-Cave: it"
10:13 AM JT-Cave: it?
10:13 AM Roguish: oh, minimum. well, depends upon the spindle of course. like 200 rpm.
10:13 AM Tom_L: predicted 2 on friday
10:14 AM JT-Cave: in hal
10:14 AM Roguish: it's up to the user. your config creator is wonderful. but the user should learn what's going on, and RTFM
10:14 AM Tom_L: i keep mine at 300 or >
10:15 AM JT-Cave: what on earth are you talking about Roguish
10:15 AM Roguish: I think my spindle min is 250
10:15 AM Tom_L: he's not from earth!
10:15 AM Roguish: don't know. just buttttin in
10:15 AM JT-Cave: must not be
10:15 AM JT-Cave: I need to figure out in hal to set a minimum spindle speed
10:15 AM Tom_L: i think he was making suggestions for minimum spindle speed
10:16 AM JT-Cave: ah well that is another subject for a different show
10:16 AM JT-Cave: prob a limit in hal
10:17 AM Roguish: check this out. https://g1.ipcamlive.com/player/player.php?alias=5e863c6e0e66d
10:20 AM Tom_L: most if not all spindle control will come from motion and i don't see any mention of min or max settings
10:22 AM Tom_L: spindle comp mentions spindle.N.max.float and spindle.N.min.float
10:22 AM Tom_L: so that would likely be where to put it
10:22 AM Roguish: mine is set in the vfd comp .ini settings
10:23 AM Tom_L: sure, not everybody will use it
10:23 AM Tom_L: it's a template to start from
10:26 AM Tom_L: but spindle comp probably won't help much with a mesa controlled spindle
10:30 AM JT-Cave: # Spindle Connections
10:30 AM JT-Cave: net spindle-vel-cmd <= spindle.0.speed-out-abs
10:30 AM JT-Cave: net spindle-vel-cmd => pid.s.command
10:30 AM JT-Cave: net spindle-pid-out <= pid.s.output
10:30 AM JT-Cave: net spindle-pid-out => hm2_[MESA](BOARD).0.pwmgen.00.value
10:31 AM JT-Cave: I "think" I just need to put a limit1 in between spindle speed out and pid command
10:31 AM Tom_L: http://linuxcnc.org/docs/stable/html/drivers/hostmot2.html
10:31 AM Tom_L: If you wanted to scale the analog out of a channel to RPM for a 0 to 6000 RPM spindle with 0-10 V control you could set the limits like this:
10:31 AM Tom_L: minlimit: 0
10:31 AM Tom_L: maxlimit: 6000
10:31 AM Tom_L: maxfullscale: 6000
10:31 AM Tom_L: (this would prevent unwanted negative output voltages from being set)
10:33 AM JT-Cave: interesting
10:35 AM JT-Cave: 7 float RW 10 hm2_5i25.0.7i77.0.1.analogout0-maxlim
10:35 AM JT-Cave: 7 float RW -10 hm2_5i25.0.7i77.0.1.analogout0-minlim
10:36 AM Tom_L: i've never messed with the 5ixx 6ixx or 7i77 stuff
10:37 AM Tom_L: and you have some with +10 -10 and 0 - +10v ranges
10:37 AM JT-Cave: 7i77 doesn't have a Six uncommitted OPTO coupler outputs are available for drive enable. Five of these
10:37 AM JT-Cave: outputs are (ENA0 through ENA4) are switched in common while ENA5 can be
10:37 AM JT-Cave: independently switched for spindle applications.
10:37 AM JT-Cave: 7i77 doesn't really have a spindle pwm drive just have to use drv 5
10:37 AM Tom_L: spindle control on mesa cards varies quite a bit i think
10:38 AM Tom_L: i get mine off the 7i47s which has 0-10v swing
10:39 AM Tom_L: with direction control
10:39 AM Tom_L: where others use -10v to +10v for both
10:41 AM Tom_L: and a lathe spindle may be different yet i dunno
10:43 AM Tom_L: i don't have limits set on mine but know to keep my cad cam around 300rpm or above
10:44 AM JT-Cave: if parent.spindleMinRpmFwd.value() > 0: # use limit1
10:44 AM JT-Cave: halContents.append('net spindle-vel-cmd => spindle-limit.in\n')
10:44 AM JT-Cave: halContents.append('net spindle-limit-cmd <= spindle-limit.out\n')
10:44 AM JT-Cave: halContents.append('net spindle-limit-cmd => pid.s.command\n')
10:44 AM JT-Cave: looks like it already is there lol
10:45 AM JT-Cave: except it's broken lol
10:46 AM JT-Cave: ah the limit1 is never created
10:50 AM JT-Cave: needs more work
10:54 AM JT-Cave: hmm limit1 does not work as expected
10:55 AM Tom_L: there are limit 2 & 3 :)
10:55 AM Tom_L: don't think those apply though
10:56 AM Tom_L: i'm not entirely sure you'll find a way to set a min limit. generally that comes within the user's knowledge and the cad cam
10:57 AM JT-Cave: limit1 if you set min to 500 and put 1 to in you get 500 out!
10:58 AM Tom_L: i was wondering that
10:58 AM Tom_L: it shortens the range
10:58 AM JT-Cave: if your spindle min rpm is 500 then that should be enforced by hal
10:58 AM JT-Cave: even if you command s4 m3 nothing should go out
10:58 AM Tom_L: because 1 on my spindle requires 500 for the pwm to start turning
10:59 AM JT-Cave: yup
11:00 AM Tom_L: that was why i think it can't be set
11:00 AM JT-Cave: it?
11:00 AM Tom_L: now, prove me wrong :)
11:00 AM Tom_L: the min spindle speed
11:01 AM travis_farmer: depends on the spindle and VFD. mine will start at around 300, but has very little power
11:02 AM Tom_L: some spindles are tuned well enough they can do 1 rpm but i think that's a small number of them
11:03 AM Tom_L: i can tell you the PID behaves different around those rpm
11:03 AM Tom_L: i bet your car cruise won't engage below 20 mph
11:04 AM JT-Cave: bet mine will engage at 0.1 mph
11:04 AM Tom_L: i'd be curious
11:04 AM JT-Cave: the truck and C8 won't below 25 mph but the insight will
11:05 AM Tom_L: most of them are around 20ish
11:07 AM travis_farmer: i wish i could buy some energy and motivation... hard to stay awake today...
11:08 AM JT-Cave: Which version of LinuxCNC are you using?
11:08 AM JT-Cave: If it is 2.9+ then you can set spindle min and max limits in the ini.
11:08 AM Tom_L: the docs & test pc i use are 2.9
11:09 AM JT-Cave: http://linuxcnc.org/docs/stable/html/config/ini-config.html#sub:ini:sec:spindle-num
11:09 AM Tom_L: the mill has 2.8 on wheezy
11:09 AM travis_farmer: 290-pre1
11:09 AM Tom_L: i didn't look for that in the ini section :)
11:09 AM JT-Cave: I found a post by Andy that mentioned it
11:10 AM Tom_L: i wonder if mesa honors that
11:10 AM Tom_L: i wonder if those are mostly for lathe
11:10 AM JT-Cave: it's part of linuxcnc
11:11 AM Tom_L: there are a couple gcode you wouldn't use on a mill
11:13 AM Tom_L: try it i guess
11:14 AM Tom_L: i can't test that
11:15 AM Tom_L: the [DISPLAY] section MIN_SPINDLE_OVERRIDE would be affected by this too
11:16 AM Tom_L: or MIN_SPINDLE_0_OVERRIDE... it mentions both
11:18 AM Roguish: wow, just hit 40
11:18 AM Roguish: it's blazin...
11:18 AM * Tom_L puts on some shorts
11:28 AM JT-Cave: me prepares for a nap
11:30 AM Tom_L: lunch first
11:37 AM * travis_farmer ate lunch, and prepares for another psudo-nap
01:21 PM Roguish: ok, just tipping into 50 territory. time for a quick, short, easy ride......
01:31 PM Tom_L: you're really pushin it now
02:01 PM andypugh: Oh! The shame! I just noticed that my Holbrook lathe is running 2.8.0-pre on Debian Wheezy with RTAI kernel 3.4.9.
02:04 PM Tom_L: hey! if it ain't broke...
02:04 PM andypugh: Well, in general, yes, but perhaps I should be actually testing my releases?
02:05 PM Tom_L: i've got 2.9.2.14 on the test pc if that makes ya feel any better
02:06 PM Tom_L: i see seb puts up rpi images now.. what would be nice is a .deb so an update can be done without a full reinstall
02:07 PM Tom_L: and the .gz does work but i hate to lose everything just to update lcnc
02:07 PM Tom_L: yeah yeah i could build from scratch...
02:07 PM -!- #linuxcnc mode set to +v by ChanServ
02:08 PM JT-Shop: whew it's warm in here
02:08 PM Tom_L: store it up, it's supposed to be 2F here friday
02:09 PM XXCoder: heat capactor would be awesome lol
02:09 PM * JT-Shop takes 5 from splitting firewood
02:10 PM andypugh: Tom_L: There are debs, at www.linuxcnc.org/dists/
02:10 PM Tom_L: oh?
02:10 PM Tom_L: i was looking on the buildbot2 site
02:10 PM andypugh: Only for 64 bit kernels, though, and only for Buster and Bookworm.
02:10 PM Tom_L: that would still be ok
02:10 PM Tom_L: i'm running bookworm on one sd
02:11 PM JT-Shop: hmm grep for MIN_FORWARD_VELOCITY in 2.9 /src and there are no hits... maybe that's why it doesn't work?
02:11 PM andypugh: Yeah, well, the buildbot is almost no help to me at the moment, I end up building everything for the releases from scratch. (With help from Rod, whi builds iso and pi images)
02:11 PM Tom_L: i tried that once but failed miserably
02:12 PM lcnc-relay: <skunkworks8841> I am not to the point of actually testing anything again.
02:12 PM Tom_L: it shows both armhf and arm64 there
02:13 PM Tom_L: ahh the armhf only has docs
02:14 PM Tom_L: i'll see if the deb update works
02:15 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/FLkWFTqflXTMrbllBuMQlLLH
02:15 PM Tom_L: too many files in too many places :)
02:16 PM Tom_L: hah tube & transistor combined
02:17 PM lcnc-relay: <skunkworks8841> I remember my dad using this and thinking it was magic.. LOL
02:17 PM Tom_L: i had an old old transistor tester but no longer do
02:17 PM roycroft: i still have my jackson tube tester
02:18 PM roycroft: https://www.ebay.com/itm/256364496966
02:18 PM roycroft: similar to that
02:18 PM JT-Shop: looks like Andy commited the spindle min/max 3 years ago
02:19 PM lcnc-relay: <skunkworks8841> Rotary smp posted a video about setting up his lathe using mesa.. Peter is a super star 🙂
02:19 PM JT-Shop: and Chris "fixed" something a few months ago...
02:19 PM Tom_L: no 2.9.2 deb at linuxcnc.org/dists just the dev one
02:20 PM Tom_L: wait.. i think i found it

02:25 PM Tom_dev: gdebi linuxcnc-uspace_2.9.2_arm64.deb
02:25 PM Tom_dev: Reading package lists... Done
02:25 PM Tom_dev: Building dependency tree... Done
02:25 PM Tom_dev: Reading state information... Done
02:25 PM Tom_dev: Reading state information... Done
02:25 PM Tom_dev: This package is uninstallable
02:25 PM Tom_dev: Breaks existing package 'linuxcnc-uspace-dev' dependency linuxcnc-uspace (= 1:2.9.1)
02:25 PM * JT-Shop gives up trying to figure out min spindle limits and goes back to splitting firewood
02:25 PM Tom_L: so i need 2.9.2.1 first?
02:25 PM Tom_L: so i need 2.9.1.1 first?
02:26 PM Tom_L: no, i have 2.9.1 installed

02:29 PM Tom_dev: Dependency is not satisfiable: linuxcnc-uspace (= 1:2.9.2)
02:29 PM Tom_L: for the dev version
02:30 PM Tom_L: arm64
02:36 PM Tom_L: the last .gz i used from buildbot2 was ok... i think that was 2.9.1
02:36 PM Tom_L: but iirc those are full installs
02:43 PM Tom_L: so for now the choice seems to be to build from source for rpi updates
02:47 PM andypugh: What happens if you set up the linuxcnc repository?
02:47 PM andypugh: Rather than manually downloading the debs.
02:47 PM Tom_L: don't quite follow
02:47 PM Tom_L: from github?
02:48 PM andypugh: Actually, if you used the _right_ Rpi image (ie the one fro LinuxCNC, rather than some random one, that should already be configured)
02:49 PM Tom_L: i'm pretty sure now that i used the one from linuxcnc because seb's is armhf not arm64
02:49 PM Tom_L: 32 vs 64 bit
02:49 PM andypugh: So, what is in etx/apt/sources.list.d/linuxcnc.list ?
02:50 PM andypugh: Sudo apt-get update should automatically update.
02:50 PM andypugh: (Not sure if the Pi gets Synaptic)
02:50 PM Tom_L: no that just returns 2.9.1

02:52 PM Tom_dev: bash: /etc/apt/sources.list.d/linuxcnc.list: No such file or directory
02:52 PM JT-Shop: just tried MIN_FORWARD_VELOCITY in a 2.9 sim and it does not limit the rpm
02:53 PM Tom_dev: that folder is empty andy
02:53 PM JT-Shop: back to turning rounds to firewood

03:02 PM andypugh: (Doesn’t anyone read the docs?)
03:03 PM Tom_L: only when i have to

04:18 PM solarwind: guys shhhh don't tell OSHA
04:18 PM solarwind: but I use BBQ propane tanks on my forklifts :P
04:20 PM solarwind: CaptHindsight can y ou find out what kind of connector automotive propane tanks use to fill up at the station? It's $0.70/L around here which is half the cost of having a forklift tank filled up
04:23 PM Roguish-shop: solarwind, you might be able to find, or make, an adapter
04:23 PM solarwind: taht's teh goal
04:23 PM solarwind: I'm going to take a few pics of the connector and see what I can do
04:24 PM Roguish-shop: THINK SAFETY
04:24 PM solarwind: Also spares me from having to wait for the gas station attendant to send someone
04:24 PM solarwind: Roguish-shop always do
04:25 PM solarwind: The cylinder specs are so vague
04:25 PM solarwind: "100lb" cylinder shows LPG capacity of 87L
04:26 PM solarwind: but does that mean 87L is 80% of its total internal volume? or is that 100% of its internal volume?
04:26 PM solarwind: Because you're supposed to fill them up to only 80% of their volume for safety reasons
04:27 PM solarwind: It lists the water capacity as 108kg
04:47 PM solarwind: Tom_L: UPS tracking page: Estimated Delivery Date Thursday 08/01/2024
04:47 PM solarwind: lol what
04:47 PM solarwind: The actual delivery date is tomorrow, which is a Monday
04:48 PM solarwind: but also their format is dd/mm/yyyy
04:48 PM solarwind: again, fucking americans...
04:48 PM solarwind: I told you, there's no standard
04:50 PM Tom_L: i've got a few propane adapters
04:50 PM Tom_L: not sure which is for what
04:50 PM solarwind: They're likely ACME/POL/CGA
04:51 PM solarwind: not for automotive tanks
04:51 PM Tom_L: RV?
04:51 PM solarwind: RV uses standard CGA/POL
04:51 PM Tom_L: pretty sure one is LH thread
04:51 PM solarwind: yeah that's CGA/POL
04:51 PM solarwind: same as acetylene cylinders, low pressure fuel gas
04:51 PM Tom_L: https://www.fairviewfittings.com/products/fittings-adapters/brass-fittings/propane-gas-fittings/propane-motor-fuel-fill-adapter-19420/
04:52 PM Tom_L: you probably want the reverse of that?
04:52 PM solarwind: Found that page earlier, need the reverse of that
04:53 PM solarwind: or at least the spec so I can machine it

04:54 PM Unterhausen: gotta ban Tom, I don't make the rules
04:54 PM JT-Shop: look before you press enter lol
04:54 PM Tom_L: i can't see that far
04:55 PM Unterhausen: we've all done it. Okay, maybe just me and Tom
04:55 PM XXCoder: once pasted entire wiki into irc lol
04:55 PM XXCoder: had to close clint
04:56 PM Tom_L: i pasted a raw jpg once

04:56 PM XXCoder: me too, couple times, PNG encoded
04:56 PM Tom_L: anyway, just wanted to make my presence known!
04:56 PM XXCoder: well its certainly known now ;)
04:57 PM Tom_L: solarwind, just picture a chunk of brass with the right threads on both ends overprices of course
04:58 PM solarwind: That link is just for POL to ACME
04:58 PM Unterhausen: there was a place near where I was consulting in california that had every fitting
04:58 PM solarwind: all my tanks have both
04:58 PM Unterhausen: it was nice, because the CMM I was working with had some ridiculous fittings
04:58 PM solarwind: the newer ACME threads have outer threads AND LH inner POL threads
04:59 PM Tom_L: i'd imagine a male fitting you need will be hard to find
04:59 PM solarwind: taht's still not a vehicle fill connector as far as I know
04:59 PM solarwind: I think the vehicle tanks have a completely different connector
05:05 PM JT-Shop: so min spindle vel what it does is if you do S100 and min is 500 the spindle runs at 500 if your version is new enough
05:05 PM Tom_L: so you got it figured out?
05:06 PM JT-Shop: Chris M helped sort it out but 2.9.0~pre doesn't work and that's the debian version
05:06 PM Tom_L: i can see that going wrong if your code relied on the spindle being 100rpm
05:07 PM JT-Shop: yup
05:07 PM Tom_L: but meh
05:07 PM Tom_L: i'm not gonna use it
05:08 PM Tom_L: back to the rpi update, do i need to add linuxcnc.org to the sources.list?
05:08 PM JT-Shop: are you pulling from linuxcnc.org?
05:08 PM Tom_L: i'm not pulling from anywhere right now
05:09 PM Tom_L: i'm pretty sure the install was a .gz from linuxcnc for bookworm 64 bit with linuxcnc pre installed
05:09 PM JT-Shop: you got me on that one
05:10 PM Tom_L: it's not a big deal i was just testing the various update methods
05:10 PM Tom_L: the 2 debs on the lcnc site don't work for 2.9.2
05:10 PM Tom_L: regular and dev
05:11 PM Tom_L: and seb's is 32bit
05:11 PM Tom_L: or at least the wrapper is
05:11 PM Tom_L: armhf
05:13 PM Tom_L: is bookworm 64 bit only?
05:14 PM Tom_L: JT-Shop, you remember the problem i had updating bullseye? starting out with armhf but the update ended up being arm64
05:17 PM Tom_L: i do see one on seb's site i might try
05:20 PM Tom_L: no that's not one
05:21 PM JT-Shop: yup
05:22 PM snakedLX is now known as snaked
05:23 PM JT-Shop: hey snaked
05:23 PM * snaked waves
05:23 PM Tom_L: sudo apt remove linuxcnc results in 'linuxcnc is not installed'
05:23 PM Tom_L: but it is
05:23 PM JT-Shop: on the rpi
05:23 PM JT-Shop: ?
05:23 PM Tom_L: yes
05:24 PM Tom_L: bookworm linuxcnc 2.9.1
05:24 PM Tom_L: i wonder if that's because it was part of the 'iso' .gz file
05:25 PM Tom_L: or whatever format pi uses
05:26 PM Tom_L: i'll try the new .gz for 2.9.2 on a fresh sd and see what happens
05:32 PM Tom_L: mmm i don't see anything to install. alot of Contents-xxx.gz etc but no installable file
05:32 PM Tom_L: most of those are empty too
05:38 PM Tom_L: so if i add a deb to the sources.list how would i format this link: http://linuxcnc.org/dists/bookworm/2.9-uspace/binary-arm64/
05:38 PM Tom_L: ?
05:41 PM * JT-Shop calls it a day
05:53 PM Tom_L: trying the new img file on the download page now
06:10 PM Tom_L: andypugh, the image on the linuxcnc/downloads page for 2.9.2 rpi4 installs as 2.9.1
06:12 PM Tom_L: linuxcnc.org/rpi-4-debian-bookworm-6.1.54-rt15-arm64-ext4-2023-11-17-1731.img.xz
06:12 PM andypugh: Hmm. Blame Rod for that, id so.
06:12 PM Tom_L: heh just letting you know
06:12 PM andypugh: It should auto-update to 2.9.2 though
06:12 PM Tom_L: i'll try, just finished booting the img
06:18 PM solarwind: Why is it so hard to find NLGI #3 grease
06:18 PM solarwind: it's never in stores, can't find it on amazon
06:19 PM Tom_L: because it's you
06:19 PM Tom_L: you want a 5gal tub?
06:20 PM Tom_L: https://schaeffersoilshop.com/products/02383-040-ultra-supreme-grease-nlgi-3
06:20 PM solarwind: Just a single cartridge would do
06:20 PM solarwind: oh that's actually not a bad price
06:21 PM solarwind: but need lithium complex or shear stable polyurea
06:21 PM Tom_L: andypugh, that worked
06:21 PM andypugh: i don’t seem to be able to post here
06:22 PM andypugh: Oh.
06:22 PM andypugh: Now I am just confiused.
06:23 PM andypugh: No, I simply can’t post my observations on NLG3 availablilty
06:23 PM andypugh: tubes
06:23 PM andypugh: grease
06:24 PM andypugh: Oh! For goodness sake!
06:26 PM andypugh: Grease GNU
06:26 PM andypugh: Grease gun
06:26 PM andypugh: No, baffled
06:28 PM Tom_L: ?
06:28 PM Tom_L: now we're both baffled
06:29 PM Tom_L: https://simplybearings.co.uk/shop/product_info.php?products_id=153290&currency=USD
06:32 PM andypugh: I was trying to post a comment to the effect that I managed to find some NLG3 grease on eBay in tubes. But that isn’t ideal as my grease gun does not take tubes.
06:32 PM Tom_L: i had an old one i had to fill from a can
06:32 PM Tom_L: messy
06:32 PM andypugh: And for hwhatever reason the sentence just wasn’t being sent.
06:33 PM andypugh: I was trying to see if it was a trigger workd or something.
06:33 PM Tom_L: so i'm wondering if those 2.9.2 deb files would install on a clean bookworm install for the rpi
06:33 PM andypugh: The cans are OK if they have the disc with a hole in it to squrt the grease into the gun.
06:33 PM Tom_L: not sure i have a way to test that
06:35 PM Tom_L: but it wouldn't have preempt-rt
06:39 PM Tom_L: enough messin with pi unless it's one i can eat
06:44 PM Unterhausen: it's amazing how strong wirewrap wire gets when you're looking at it in a microscope
07:28 PM roycroft: the real strength of wirewrapping is in the hardened, square posts, which dig into the wire as it's wrapped around them
07:29 PM roycroft: wire wrapping is still very common in telco central offices, for good reason
07:30 PM roycroft: i don't work in the broadcasting industry, but i should imagine it's common there as well
07:42 PM Tom_L: they must use some non corrosive metals
07:43 PM lcnc-relay: <zincboy_ca_on> LOL. Not for a few decades.
07:44 PM lcnc-relay: <zincboy_ca_on> Even in telco I can't imagine it is used much except for legacy final mile stuff.
07:50 PM Tom_L: don't they use those punch down connections now?
07:53 PM lcnc-relay: <zincboy_ca_on> Yes, for any of the twisted pair connections in the local station. Then it is converted to digital and sent over IP. The days of SONET and ISDN are long gone. At least for new installs. I am sure
07:53 PM lcnc-relay: <zincboy_ca_on> there are tons of those systems still out there because no one is investing in new land line infrastructure unless it supports DSL primarily.
07:59 PM Tom_L: land lines are probably disappearing anyway
08:03 PM roycroft: punch down blocks are used at customer premises
08:04 PM roycroft: but a 66 block is designed for a very low number of cycles - a half dozen or so and then they stop working effectively
08:04 PM roycroft: whereas wire wrap terminals can be used over and over again
08:04 PM roycroft: in a central office, where there are frequent routing changes, that is a great benefit
08:11 PM lcnc-relay: <zincboy_ca_on> I thought everyone had gone to a DSLAM with fiber backhaul to the central office. I wasn't aware that there were many pure analog connections still in operation.
08:22 PM roycroft: there are still plenty of pots lines in the universe
08:23 PM roycroft: but even when there are digital connections, there still needs to be a lot of cross-connects in the central office, at least in the united states
08:23 PM roycroft: our incumbent local exchange carriers own and operating the central offices
08:23 PM roycroft: but they are required to provide collocation space to competing carriers, and make their cable plant available to the competition
08:24 PM roycroft: that's generally done with discrete cable connections in the central office
08:25 PM roycroft: and the competitors generally locate their dslams in the central office, so they need copper pairs from the ilec
08:26 PM roycroft: it's been a while since i worked for a telco, and things are changing, certainly, but much of that legacy cable plant infrastructure is still intact and in active use
08:47 PM XXCoder: yeah some stuff move slowly because its so expensive
08:58 PM roycroft: also the old model amortized the cost of cable plant infrastructure over 40 years
08:59 PM roycroft: so a lot of it isn't paid for yet
09:52 PM lcnc-relay: <skunkworks8841> work just converted thier t1 lines to fiber...
09:52 PM lcnc-relay: <skunkworks8841> Plus that gave us backup internet over fiber.
10:11 PM Unterhausen: I just used the wirewrap wire to fix a circuit board. Not sure I'll ever make a circuit that way again
10:13 PM Unterhausen: I have some strain gauge hookup wire somewhere, it knows I'm looking for it and is hiding.
10:48 PM duatepe: Hi everyone, I am new in LinuxCNC. I started a new job and we making a CNC machine and my boss want me to enable TCP mode with that, so as you see I dont have any information about that, I have read linuxcnc doc as much as I can to understand cnc basics and linuxCNC and now I think I reached the  point to ask this question and understand the
10:48 PM duatepe: answers. Now My first question -> does the any variable exist to enable the TCB mode or should I make some math for that
10:56 PM lcnc-relay: <skunkworks8841> Sorry? Tcp?
10:57 PM duatepe: TCP means Tool Center Point

11:03 PM solarwind: LOL $200 for a snap on ratchet?
11:03 PM solarwind: who the hell buys that shit...
11:03 PM solarwind: overpriced trash
11:03 PM lcnc-relay: <skunkworks8841> Have you searched the forums.. I think I remember it talked about there - switchkins?
11:08 PM duatepe: I started to search and I didnt get starter results, that is why I asked here at first maybe this platform can give me a way to understand the basics about that like some docs, right pages of forum. I am  beginner that is why the best one first asking the basic question and going to right points
