04:25 AM Tom_L: morning
04:30 AM Loetmichel: Hehe, HP 17" notebook, 900 eur. Just delivered. 25min -> Puzzle... I am getting faster... :) http://www.cyrom.org/palbum/main.php?g2_itemId=18131&g2_imageViewsIndex=1
04:32 AM XXCoder: whats you doing with it?
04:33 AM Loetmichel: making a full alu enclosure for it
04:33 AM XXCoder: ah for miliary or whatever?
04:33 AM Loetmichel: yep
04:37 AM travis_farmer: i thought laptops for mills had bad latency
04:37 AM Tom_L: not for a mill
04:37 AM Tom_L: and most do yes
04:38 AM Loetmichel: travis_farmer: real military. (more like: services). Our systems are shielded against eavesdropping
04:38 AM Loetmichel: the enclosure i am designing right now for it will be around 5kg alu
04:39 AM travis_farmer: oh, i see, i mis read

08:42 AM JT-Shop: Hello my uncle is interested in this. Do you have a phone number he can contact you at? He has a few questions
08:42 AM JT-Shop: ask questions here
08:42 AM JT-Shop: I’m not with my uncle to be able to ask the questions. He does not have Facebook
08:42 AM JT-Shop: He wanted to come pick it up today if it’s what he was looking for. He is in poplar bluff
08:42 AM JT-Shop: I’m on the phone with him now. He asked if you could send address so he can come look at it.
08:43 AM JT-Shop: I won't be here this afternoon, I could show it tomorrow
08:43 AM JT-Shop: I’ll have to call & ask him if he wants to do that or not. He lives in malden they are in poplar bluff today. I know he won’t want to drive up there not knowing the information he needs to know about the machine. So if you don’t want him to call he will more than likely pass on the machine
08:43 AM JT-Shop: if uncle doesn't have fb how does he know I have this for sale?
08:45 AM Tom_L: :)
08:48 AM * JT-Shop passes
08:48 AM travis_farmer: lol
08:48 AM JT-Shop: malden is 30 miles from poplar bluff so that's no excuse lol
09:00 AM Tom_L: maybe the nephew showed it to the uncle on his fb
09:01 AM Tom_L: so is fb market more popular than craigslist now?
09:01 AM Tom_L: i don't use either one
09:02 AM JT-Cave: seems no on looks on craigslist anymore
09:02 AM JT-Cave: or at least I never get any response to my ads so I quit using it
09:03 AM JT-Cave: in any case call your uncle and post his question
09:03 AM JT-Cave: the ad has a complete description of the 3-1 machine
09:03 AM Tom_L: you never know what you're gonna run into anymore
09:06 AM JT-Cave: I never give out my phone number unless they are on the way to buy it and the conversation has been legit
09:13 AM Tom_L: a friend on irc has mine and called me once from Canada because i'd been on vacation and didn't wanna publish it. he got worried because i'd been off irc a few days
09:17 AM Unterhaus_ is now known as Unterhausen
09:17 AM Unterhausen: Everyone worries if you go to Canada, it's a jungle up there and they don't rake their forests like civilized countries do
09:33 AM roycroft: they don't need to - all the forests in canada are burning down
10:01 AM roycroft: i went up to salem yesterday (about an hour's drive) to pick up a stick of 2"x2" square tubing for my headache rack project - a 20' stick was for sale for $30, making it worth the trip
10:01 AM roycroft: when i got there it turned out to be 2" round tubing instead
10:01 AM roycroft: $30 is still a great deal for that, so i got it
10:02 AM roycroft: but now i have to redesign the rack, and figure out how tight a radius i can bend in the tubing
10:02 AM roycroft: it will actually be a much better looking rack in the end, if i make it well, but i'm not used to fabricating with round tubing
10:02 AM Tom_L: fill with sand before bending
10:03 AM roycroft: i have a tubing roller and a tubing notcher
10:03 AM roycroft: if i were using a bender i would do that for sure, tom_l
10:03 AM roycroft: i shouldn't need to with the tubing roller
10:04 AM roycroft: the rule of thumb with a tubing roller is a bend radius 10x the diamater of the tubing, but i need it to be closer to 5x
10:04 AM roycroft: hopefully i can pull that off
10:05 AM roycroft: i need the bend angle to be 71 degrees, which should be much easier than 90 degrees
10:06 AM roycroft: i wasn't too impressed that the ad said "2x2x0.120" and then it turned out to be round
10:07 AM roycroft: and the seller was a business - they fabricate off-road accessories for jeeps
10:07 AM roycroft: one would think they would know the difference between square and round tubing
10:10 AM rmu: is this a steel tube?
10:10 AM Tom_L: not 4130 is it?
10:11 AM Tom_L: offroad for jeep kinda makes me wonder if it is
10:12 AM Tom_L: i 20% blame you for realising it's an offroad fab place and afik they only use round tube unless it's an actual frame
10:13 AM Tom_L: for that purpose it's going to be structurally stronger
10:16 AM Unterhausen: It's always a good bet that it's roycroft's fault
10:16 AM Tom_L: hah
10:22 AM Deejay: re
10:36 AM JT-Shop: my shape is getting too round
10:41 AM travis_farmer: "<JT-Shop> my shape is getting too round", i think i have the same problem, getting too round :-)
10:52 AM Unterhausen: "deadlines make the framebuilder sad" is my new shop motto
10:53 AM Scopeuk: "failure to plan on your part does not constitute and emergency on mine"
10:54 AM Unterhausen: is there a good video editor on linux. Need to edit some videos for youtube.
10:55 AM Scopeuk: openshot?
10:56 AM Scopeuk: I heard good things but haven't tried it in a long time
10:56 AM Unterhausen: I'll try it, thanks. Anything to get rid of my stammering
10:57 AM JT-Cave: I use Flowblade
10:59 AM Unterhausen: JT which version of flowblade? Just the debian version?
11:35 AM JT-Cave: yup
11:36 AM JT-Cave: mine is version 2.8
11:38 AM Unterhausen: thanks
11:38 AM Unterhausen: there is a hurricane over Cleveland
11:39 AM Unterhausen: sorry, it's over Erie now
11:40 AM JT-Cave: hmm a video I posted the other day has 1.1k views for some reason
11:41 AM * JT-Cave thinks it's nap time
11:42 AM * travis_farmer thinks JT is correct, it is nap time...
11:44 AM Unterhausen: it's always nap time
11:45 AM travis_farmer: ;-)
12:04 PM Unterhausen: one of our videos about diamond turning has over 600k views. Nobody knows why
12:06 PM Unterhausen: weird comments on that video, as expected
12:07 PM Unterhausen: The one that might make the least sense " It all looks pretty nice but a bit of a one trick pony machine brought about than more than just the cutting insert , probably alot to do with the bearings and geometry of the machine."
12:08 PM Unterhausen: yeah, the machine, the tool and the bearings probably have a lot ot do with 1.6nm Ra
12:39 PM JT-Shop: lol
01:08 PM Loetmichel: Unterhausen: if you make a lens with that out of acrylic: do you still need to polish it?
01:12 PM JT-Shop: Unterhausen, I have one video that has 47k views for some reason
01:17 PM travis_farmer: i love SSH... i installed Debian 12 on my LinuxCNC computer (different hard drive from the running copy), and now i can finish up some task over SSH from the comfort of a good seat, and my laptop. :-)
01:19 PM Tom_L: i run my server headless
01:19 PM travis_farmer: all mine are as well :-)
01:31 PM roycroft: all my servers are headless
01:32 PM roycroft: and most run in a virtualized environment
01:32 PM travis_farmer: mine are VE as well, roycroft :-) using Proxmox VE
01:33 PM roycroft: yes, i use pve these days as well
01:33 PM roycroft: i have one old system that still runs under vmware esxi, but the client isn't willing to pay a few dollars to upgrade the machine
01:34 PM roycroft: it's funny, though, that they're willing to pay several hundred to a couple thousand dollars per month for admistering that machine, because it breaks a lot
01:35 PM roycroft: and rebuilding it would fix almost all their problems
01:35 PM roycroft: but they're government, with weird government accounting systems
01:35 PM travis_farmer: sounds about right
01:35 PM roycroft: they have budget for maintenance, but no budget for replacement
02:15 PM JT-Shop: what does proxmox ve do?
02:16 PM travis_farmer: it allows you to run many virtual machines on a single computer (server). i currently run my web server and FreePBX server on one server.
03:22 PM -!- #linuxcnc mode set to +v by ChanServ
03:44 PM travis_farmer: there, just went out and confirmed LinuxCNC would startup on the fresh install of Debian 12, and after compiling in a bunch of comp programs, it ran perfectly. i have not formatted the previous drive yet, just in case. but the latency on Debian 12 looked better than when i ran Debian 11. more testing tomorrow, before i format the old drive. :-)
03:58 PM roycroft: debian 12 is still kicking my butt a little
03:58 PM travis_farmer: how so?
03:58 PM roycroft: currently i'm dealing with a lot of php7.4 crap that doesn't work right with php8.2
03:58 PM roycroft: and a boss who doesn't want to fix the problems
03:59 PM roycroft: prior to that i had some issues with mysqlbackup, but i've worked through those
03:59 PM roycroft: and prior to that i had some amanda/xfsdump issues, which i never resolved, but came up with a lousy work-around
04:01 PM travis_farmer: hmmm, don't know what to tell you... not actualy being there...
04:11 PM roycroft: this is not the first time an os upgrade has presented challenges to me
04:11 PM roycroft: but i can say it's caused more issues than any recent debian upgrade
04:12 PM roycroft: i still don't know what the amanda/xfsdump problem is all about
04:12 PM roycroft: but the other two are due to mariadb and php upgrades
04:12 PM roycroft: neither of which is a bleeding edge release under debian 12, so i'm not blaming the debian folks at all for any of that
04:13 PM XXCoder: JT-Cave: omg you filmed a mythical animal
04:21 PM travis_farmer: XX, i had to really dig deep to figure out what you were talking about... ;-) then i remembered YT ;-)
04:25 PM XXCoder: travis_farmer: lol yea
04:48 PM * travis_farmer signs off to enjoy some sweet-n-sour kielbasa :-)
04:50 PM * roycroft has a board meeting tonight, so it will be a quick dinner
04:52 PM XXCoder: have a fun meeting
04:55 PM roycroft: i wrote one of the motions that will be new business tonight
04:55 PM XXCoder: cool. well i hope you succeed
04:56 PM roycroft: my motion will be added, for sure
04:56 PM roycroft: but it won't be old business and voted on until next month
04:56 PM roycroft: i'll be curious about member comments on the motion, though
04:57 PM roycroft: that's why we move from new to old after a month - to give the membership time to comment on a motion before it goes to a vote
04:57 PM XXCoder: yeah thats best way reallyu
04:57 PM * roycroft heads off to the scrap yard in search of some metal
05:17 PM Unterhaus_ is now known as Unterhausen
05:18 PM Unterhausen: I wish the scrapyard was closer. On the bright side, it's full of railroad parts
05:19 PM JT-Shop: hmm I thought I had a failed camera but the camera is fine... checks cable now
05:20 PM XXCoder: unicorn probly broke it
05:23 PM JT-Shop: 2 screws for the C8 were $10.02 each but I got them at wholesale price of only $6.89 each
05:23 PM JT-Shop: unicorn can't get into the chicken yard where that camera is
05:24 PM XXCoder: lol
05:47 PM Tom_L: must be some damn good bolts
05:50 PM JT-Shop: t15 screws with large plastic washer
05:57 PM * JT-Shop calls it a night
06:11 PM roycroft: there was no scrap metal even remotely approching what i need
06:11 PM roycroft: in fact, there's virtually no scrap metal to be had except in huge sizes
06:11 PM roycroft: i guess that's part of the inflation thing
06:12 PM roycroft: i needed some angle, and the smallest scrap angle they had was 8x8x1/2
06:12 PM * roycroft ended up buying new, but still came out ok
06:35 PM Tom_L: oh for the trailer project?
07:25 PM roycroft: actually, this was for the headache rack
07:25 PM roycroft: i still need to figure out whether or not i can rebuild the brakes for the trailer
07:26 PM roycroft: if not, i'll need a new axle and wheels, and that would cause a rethink of the whole project
07:26 PM roycroft: but i ran across the tubing for the headache rack really for really cheap, so i'm going to go ahead and fab that first
09:22 PM -!- #linuxcnc mode set to +v by ChanServ
11:33 PM roycroft: i survived the board meeting
11:33 PM roycroft: but it was moving back towards dysfunction
11:33 PM roycroft: i though we were moving forward a wee bit
11:33 PM XXCoder: man those can be nasty war
11:35 PM roycroft: we have an election coming up in october
11:35 PM roycroft: 1/3 of our board members will be up for reelection
11:36 PM * roycroft moves on to other things
11:37 PM roycroft: i'm looking at getting some fixturing gear from fireball tools, over in spokane
11:37 PM XXCoder: pretty long drive
11:37 PM roycroft: i'll have them shipped
11:38 PM roycroft: https://fireballtool.com/products/magic-square
11:38 PM roycroft: that looks like it would be a good first fixturing tool from them
11:38 PM roycroft: very versatile
11:39 PM roycroft: they make a big cast iron welding table
11:40 PM roycroft: that would be really neat if i had the room for it, but i'd be afraid of breaking it
11:41 PM XXCoder: heavy I bet. taking off pallet is big thing
11:41 PM roycroft: it's 4-1/2' x 8-1/2', and a foot thick
11:41 PM roycroft: i think if i got it and put it in my shop the shop floor would sink
11:47 PM roycroft: if it's ductile cast iron i wouldn't be so afraid i'd break it
11:47 PM roycroft: but it would be more unaffordable
11:52 PM roycroft: the casting would weigh about 7500kg
11:52 PM roycroft: there are holes drilled in it
11:53 PM roycroft: a lot of holes
11:53 PM XXCoder: yeah air cooling and weight loss holes ;)
11:53 PM roycroft: but they're relatively small
11:54 PM roycroft: it's still heavy, even with the holes
11:54 PM XXCoder: anyway yeah very heavy. shop I worked at dont weld so they dont have such
11:54 PM XXCoder: yea was joking with it
11:57 PM roycroft: i don't do a lot of welding, but i would like to be able to fabricate more accurately
11:58 PM XXCoder: one of interesting uses for 3d printing is making holders
