12:00 AM XXCoder: it is
12:07 AM XXCoder: its on rotating base thats different from orginial
12:07 AM unterhausen: I guess it's worth $30k to someone
12:07 AM XXCoder: wha one sells for 30k?
12:07 AM unterhausen: the patent
12:07 AM XXCoder: oh
12:07 AM unterhausen: google says $15k-20k
12:11 AM roycroft: that's probably going to be a $3500 vise
12:12 AM XXCoder: likely
12:12 AM XXCoder: kurt kurts your wallet
12:12 AM XXCoder: that vise needs a lot more machining work
12:24 AM unterhausen: I go out of my way to buy vises that don't rotate
12:24 AM unterhausen: I suppose it might be good for engraving though
12:25 AM roycroft: engraving vises need to rotate
12:27 AM unterhausen: makes sense
12:27 AM unterhausen: is that what the original was for?
12:28 AM roycroft: i have no idea
12:28 AM roycroft: but that's what the current version is for
12:31 AM unterhausen: it's pretty, looks like a lot of grinding
12:32 AM XXCoder: it could be solution looking for problem
12:32 AM roycroft: if i were doing a lot of engraving on odd-shaped objects i might have some interest in it
12:32 AM roycroft: but a pin vise works too
12:32 AM roycroft: and is a lot easier and less expensive to make
12:32 AM unterhausen: I want one, not going to buy one though
12:33 AM XXCoder: theres few 3d printable ones out there now
12:34 AM unterhausen: for some of the things I do, it would be worthwhile to have more than two vise faces
12:34 AM unterhausen: have to think about that
12:34 AM roycroft: think of how much fun it would be to index your part on a fractal vise
12:34 AM roycroft: especially one that rotates
12:34 AM XXCoder: its not repeatable too
12:34 AM XXCoder: so small batches only
12:35 AM roycroft: sure it is
12:35 AM unterhausen: when he was messing with it, I just wanted him to lock the rotation
12:35 AM roycroft: but it might take an hour to repeat each time :)
12:35 AM roycroft: for engraving it's fine
12:35 AM unterhausen: good for hand work only
12:35 AM XXCoder: lol repeatable as in just loosen, remove part, insert next part, tighten without any adjustment
12:35 AM roycroft: engraving is done freehand and it's usually easier to rotate the part than to rotate the person doing the engraving
12:36 AM roycroft: so this mail merge is going horribly on my laptop
12:36 AM * roycroft moves to the imac to see if he has better luck there
12:37 AM unterhausen: someone just sent an email to the lcnc list that changed the line length
12:37 AM unterhausen: every other line has a single word on it
12:38 AM unterhausen: it's about midnight commander, I think I can safely delete
12:40 AM roycroft: we have a meeting tomorrow night, and we're going to have a stamp applying party during the meeting
12:40 AM roycroft: i have about 1200 postcards to print that need to be ready for that
12:40 AM roycroft: i've been fighting with the printer driver for days to get it to do 4-up on card stock, and finally got that working tonight
12:40 AM roycroft: so the text side of the postcards are now done
12:41 AM roycroft: then i went to do the mail merge for the address side
12:41 AM roycroft: libre office crashes constantly while trying to do the mail merge
12:41 AM roycroft: but it worked fine the other day doing the same thing
12:42 AM roycroft: i have things to do tomorrow, but nothing pressing - i took care of all my weekend chores today, so i have all day tomorrow to get this done if i need that much time
12:42 AM roycroft: i really wanted to get it done tonight though - i'll sleep better knowing it's done
12:44 AM unterhausen: the worlds most famous violins were treated with a secret chemical mix
12:44 AM unterhausen: It's going to turn out to be cat urine
12:45 AM roycroft: stratavarius used cochineal varnish on his violins
12:45 AM roycroft: it's the most expensive varnish in the world - only a couple folks make it these days, and it goes for $300/oz
12:46 AM roycroft: amd ot
12:46 AM unterhausen: nice
12:46 AM unterhausen: well, you have to catch the female beetles
12:47 AM roycroft: and cochineal is made of bug guts
12:47 AM roycroft: not the same as cat pee, but a similar kind of thing
12:49 AM unterhausen: that's not really a secret though, is it?
12:51 AM unterhausen: someone found out they were treated with "mineral salts"
12:54 AM unterhausen: theory is that they were insecticide
01:00 AM roycroft: it is working on the imaca
01:00 AM roycroft: imac
01:00 AM roycroft: or seems to be, at least
01:00 AM roycroft: it's merging, not crashing
01:01 AM unterhausen: what os on laptop?
01:07 AM roycroft: the exact same os with the exact same patch level
01:07 AM roycroft: and the application software is exactly the same on both machines
01:07 AM roycroft: that's what is so infuriating
01:17 AM Deejay: moin
01:18 AM unterhausen: the wifi on the pi is picking up the network from 2 houses down
01:19 AM unterhausen: it also listed all the rokus in this house
01:55 AM roycroft: what a pain in the butt
01:55 AM roycroft: i got the mail merge data working
01:55 AM roycroft: but i have to save to pdf - i cannot print directly
01:55 AM roycroft: but on my imac i cannot print the pdf to my printer
01:55 AM roycroft: i have to copy to my laptop and print from there
01:56 AM roycroft: and i cannot print the return address at the same time as the mail merge data
01:56 AM roycroft: so i have to run everything through the printer a third time
01:56 AM roycroft: it's a good thing my printer is fast (40 sheets/minute)
02:02 AM * roycroft will at least be able to sleep well tonight, knowing it's done
05:43 AM Tom_L: morning
05:43 AM XXCoder: yo
07:05 AM unterhausen: the only mouse I found so far for the Pi has lights that change and it's really getting on my nerves
07:05 AM XXCoder: tapes is your friend ;)
07:12 AM unterhausen: it would look like that first mouse that bill gates carved out of balsa
07:12 AM unterhausen: only with tape
07:12 AM XXCoder: i goit anoher idea if you got a 3d printer
07:12 AM unterhausen: I do, but maybe I'll use a hammer
07:12 AM unterhausen: much faster
07:13 AM XXCoder: 3d print a new case for mouse
07:14 AM unterhausen: the pi4 system font is set for a small screen, so the text is about 1/8" tall on this one
07:15 AM unterhausen: I guess I should take the little dog to the ER, she won't put weight on one of her front legs
07:15 AM XXCoder: tiny
07:15 AM XXCoder: :( hope dogs ok
07:33 AM unterhausen: well, we're going to the ER
07:36 AM unterhausen: turns out even dogs can get a crick in their neck from sleeping wrong
07:37 AM XXCoder: its mammal thing i guess
07:42 AM unterhausen: I have a facebook friend in France, and half of his posts are memes in French
07:42 AM unterhausen: Took me 7 hours to get the joke on one of them
07:50 AM unterhausen: Every hot dog you eat shortens your life by 36 minutes
08:42 AM skunkworks: well - fresh install of debian 11 on my laptop. Suprisingly painless.
08:42 AM skunkworks: even have dedicated video card passthrough working with my win10 vm
08:43 AM skunkworks: So - went from 9 to 11
08:48 AM -!- #linuxcnc mode set to +v by ChanServ
09:47 AM JT-Cave: well crap Beginning August 13, 2021, we will no longer accept account passwords when authenticating Git operations on GitHub.com.
09:53 AM JT-Cave: found the issue [remote "origin"] was set to https and should have git for ssh
09:54 AM Tom_L: so what will they accept?
09:55 AM JT-Cave: ssh key or personal token
09:55 AM Tom_L: oh
09:55 AM JT-Cave: I use ssh but somehow when I cloned I got https
09:56 AM JT-Cave: all right off to the machine shop
10:36 AM JT-Shop: ordered from amazon friday, they shipped it usps and it's out for delivery... curious to see who delivers it
10:46 AM jdh: I get amazon stuff on sundays from usps
10:50 AM JT-Shop: is it a usps vehicle?
10:50 AM JT-Shop: I've gotten stuff from a little amazon vehicle
10:58 AM Tom_L: yeah if it's on a sunday usually it's an amazon truck
11:02 AM JT-Shop: tracking shows it being handed off this morning at 5am
11:10 AM Tom_L: around here some just drop and run, no doorbell notification etc
11:10 AM Tom_L: good thing is, amazon ones you can track on google maps
11:10 AM JT-Shop: I have a driveway alarm if I'm awake
11:10 AM JT-Shop: really?
11:11 AM JT-Shop: how so?
11:11 AM unterhausen: everything gets delivered by usps in a usps vehicle here
11:11 AM Tom_L: tells you how many more stops before yours
11:11 AM CloudEvil: They started doing that a couple years ago here.
11:11 AM JT-Shop: how?
11:11 AM Tom_L: some of them at least
11:11 AM CloudEvil: Works well, I even get a lil map.
11:11 AM unterhausen: I think it depends on if they hire a contractor for amazon deliveries
11:11 AM Tom_L: has a dot on the map showing delivery truck progress
11:11 AM CloudEvil: It's on the order info page.
11:11 AM CloudEvil: If it's applicable for your order.
11:12 AM Tom_L: yeah not all of them do that
11:12 AM CloudEvil: Indeed.
11:12 AM Tom_L: typicaly the sunday ones do
11:12 AM CloudEvil: I get it for all direct amazon deliveries.
11:12 AM unterhausen: I try not to get sunday deliveries, old fashioned grew up with blue laws kind of person
11:12 AM Tom_L: i generally don't check every one
11:13 AM JT-Shop: they must not have maps of swamp east missouri lol
11:13 AM Tom_L: maybe they show it underwater :)
11:14 AM JT-Shop: hmm looks like you have to sign up for delivery alerts
11:15 AM JT-Shop: is that a phone app?
11:16 AM unterhausen: THey really want you to use their app, so it wouldn't surprise me
11:16 AM unterhausen: $300 later, no idea why the dog got up lame. Must have slept wrong, she's not back to normal, but walking now
11:17 AM JT-Shop: gotta build the dog a dog support with wheels :)
11:19 AM Tom_L: some delivery alerts are with a phone app yes
11:20 AM Tom_L: usps, you're lucky if their web one works
11:22 AM unterhausen: I was thinking about the wheels this morning, she was hit by a car so one shoulder is a real mess
11:22 AM unterhausen: and the other leg is short
11:26 AM JT-Shop: dang, is her name Lucky?
11:28 AM Tom_L: had ice on my shoulder since about 4am, now at least i can move it around a little
11:28 AM Tom_L: dunno what i did
11:28 AM unterhausen: I try not to think about her previous life, she's such a sweetheart I imagine her previous family misses her
11:28 AM unterhausen: Can a dog get repossessed by a vet for non-payment?
11:29 AM Tom_L: you need to find an old school vet
11:29 AM JT-Shop: she was a stray?
11:29 AM Tom_L: not a money grubbin one
11:29 AM unterhausen: we got her from a pet rescue
11:29 AM JT-Shop: cool
11:29 AM unterhausen: all the vets charge a lot around here
11:30 AM unterhausen: probably have to drive a couple of hours to get to the old $10 visit ones
11:30 AM unterhausen: plus this was an ER visit
11:30 AM unterhausen: don't want to go to the ER vet, every other pet that arrived ended up in a box
11:31 AM unterhausen: lots of crying
11:31 AM unterhausen: "Please remit $125" "here are your dog's remains, have a nice day"
11:34 AM Tom_L: i found a retired farm vet that want's to keep busy but can't do all the big animals now
11:36 AM JT-Shop: dangerously close to nap time here...
11:53 AM unterhausen: wife is in charge of vet selection, but she was at the beach so I had to take over
11:57 AM unterhausen: only one vet open on weekends and nights around here anyway
12:59 PM Eric_ is now known as unterhausen
12:59 PM unterhausen: a bike parts manufacturer posted a pic of a batch of parts on a 3d printed manifold of some kind
12:59 PM unterhausen: https://www.instagram.com/p/CS4YRHdLgz3/
01:01 PM Tom_L: we used to have a guy here that made bike parts
01:02 PM JT-Shop: weird onecnc inserted a t0 ho d0 in the code
01:02 PM Tom_L: odd
01:03 PM Tom_L: empty pocket
01:04 PM JT-Shop: actually in the tool comments section... I think that is in response to my custom g code insertion
01:05 PM Tom_L: i've been fiddling with my post for several years off and on to get it just so
01:05 PM Tom_L: adding helpful things along the way etc
01:06 PM Tom_L: like an op stop section in the post that handles the coolant & spindle off and on with a single user event in the cad
01:08 PM Roguish: oh joy. just got an invoice from a hospital for services in Feb 2020 year and a half ago.
01:09 PM Tom_L: yeah they all like to bill separately
01:10 PM Roguish: this is UCSF. supposed to be one of the best in the US.
01:10 PM Tom_L: hospital, doctor, anesthesiologist...
01:10 PM Tom_L: the hospitals love to pad the bill too
01:11 PM Roguish: doesn't even say. just 'past due' haven't heard from them since 4/20
01:11 PM Tom_L: ask for a detailed invoice
01:11 PM Roguish: they may have trouble collecting this one.
01:12 PM Tom_L: they tried billing things like 3-4 gowns for a 1 night stay all sorts of things that were never used etc
01:12 PM Tom_L: they don't expect you to read the bill
01:12 PM JT-Shop: yea I got one like that for 3-4 years ago I just ignored it
01:12 PM Roguish: just went through all the bills and payments and insurance statements. don't see anything that adds up correctly
01:12 PM Tom_L: and you never will :)
01:12 PM JT-Shop: Roguish, I uploaded the deb for gcode got a good start on canned cycles
01:13 PM Tom_L: jt you don't get thanked enough
01:13 PM Roguish: JT-Shop, cool. i'll get it today.... keep up the good work.
01:13 PM JT-Shop: thanks
01:14 PM Roguish: had an issue with rigid tapping (air cutting...). spindle went on, head went down, spindle stayed on, head stayed down.....
01:14 PM Tom_L: not good
01:14 PM Roguish: my 'lincurve' only had positive rotation.
01:15 PM Tom_L: oh i remember reading that
01:15 PM Roguish: and only 16 interpolation points. not enough to add reverse.
01:15 PM Tom_L: did andy add the new one?
01:16 PM Roguish: found the source. changed 16 to 33, compiled and installed. added reverse. much better.
01:16 PM Roguish: what new one?
01:16 PM Tom_L: lincurv
01:16 PM Tom_L: or are you just patching the first one
01:16 PM Roguish: didn
01:17 PM Roguish: didn't know he changed anything. I grabbed the source in master.
01:18 PM Tom_L: k
01:19 PM Roguish: after that I started tramming the spindle
01:19 PM Roguish: the head rotates (B axis) but does not tip (A axis).
01:20 PM Roguish: got it close enough for now in rotation. checked the front to back.....the A rotation. out be like 8-10 thou
01:21 PM Roguish: frick.
01:21 PM Roguish: don't know if the column is tipped (it bolts to the base) or if the head is tipped on the column, or both.....
01:23 PM Roguish: gotta go clean out the bathroom sink drain. running really slow...........bbl
01:29 PM Tom_L: tramming is always fun
01:34 PM unterhausen: I'm curious how people trammed the head on my mill, it's all rigid mounting
01:34 PM Tom_L: you sure they did?
01:34 PM Tom_L: i used shims on mine
01:38 PM unterhausen: I assume bridgeport checked it
01:38 PM Tom_L: probably
01:38 PM Tom_L: didn't know what kind you had
01:43 PM CaptHindsight[m]: I need to grind the surface of my BP's table
01:44 PM JT-Shop: crap I can't figure out why this part the chamfer is twice the size it should be
01:45 PM CaptHindsight[m]: wrong angle?
01:45 PM CaptHindsight[m]: check your math?
01:46 PM JT-Shop: it's generated by onecnc exactly like the last one that works great
01:46 PM CaptHindsight[m]: cold snap here down to 80F for the day, before back to 90's
01:46 PM JT-Shop: the j offset is the same
01:48 PM JT-Shop: I found it, I added a circle with the hole size not the finished chamfer size so it's operator error selecting the wrong hole
01:50 PM Tom_L: JT-Shop, i found my chamfer tool didn't come to an exact point so i have to allow a little for it
01:50 PM CaptHindsight[m]: <insert sophomoric punchline here>
01:51 PM JT-Shop: yes, I know the point diameter and enter that in onecnc
01:52 PM Tom_L: i don't have that luxury, i calculate the offset and enter it as a tool offset
01:52 PM Tom_L: cad is too old for those perks
01:53 PM JT-Shop: I'm just glad the chamfer tool didn't dig into my new vise jaws
01:53 PM Tom_L: yeah
01:53 PM JT-Shop: well it's an easy fix and only scrapped a couple of tiny bits of 6061
01:53 PM Tom_L: i have made the mistake of using the point depth instead of the full drill depth before too :)
01:57 PM Tom_L: you use softjaws for those or parallels?
01:58 PM Tom_L: ick. hi 93F tomorrow 97
02:03 PM solarwind: I gave someone a hand with something and they said "thanks, that was mighty white of ya"
02:04 PM solarwind: Joke's on them; although I do have the same skin tone as a white person, I'm not "white".
02:04 PM CaptHindsight[m]: people get their metaphors wrong all the time
02:05 PM solarwind: CaptHindsight[m] what are you doing, go work on your dyno project!
02:05 PM solarwind: I need to build one too
02:06 PM CaptHindsight[m]: Dear Dopey Friend: I'm not working on a dyno. YOU were supposed to be finding me parts for one.
02:07 PM CaptHindsight[m]: why do you think they call it "dope"?
02:08 PM solarwind: doop, thick sauce
02:09 PM solarwind: Hopefully safe to drop the charade now
02:09 PM solarwind: I moved that 1984 LeBlond Makino CNC mill into the workshop
02:10 PM solarwind: I've been busy getting that up and running. It's been so incredibly fun and exciting
02:11 PM solarwind: The brushed DC servos made it easy to test with a bench power supply
02:11 PM * CaptHindsight[m] thinking about vacuuming and mopping today, hit the horizontal surfaces with the compressed air
02:13 PM CaptHindsight[m]: we get this cotton-like dust that coats everything
02:13 PM solarwind: CaptHindsight[m] what colour?
02:14 PM CaptHindsight[m]: grey-ish
02:14 PM solarwind: THe one on the ceiling in my workshop is pink. Cotton like as well
02:14 PM CaptHindsight[m]: the filters on the AC look like dryer filters
02:14 PM solarwind: but it was from the previous tenant
02:14 PM solarwind: My dust is entirely saw dust and grinding dust
02:15 PM CaptHindsight[m]: few mm thick in a month or two
02:15 PM solarwind: Asbestos?
02:15 PM CaptHindsight[m]: https://www.hgtv.com/outdoors/flowers-and-plants/trees-and-shrubs/all-about-cottonwood-trees
02:16 PM CaptHindsight[m]: in the spring it is thick enough to roll off the outdoor AC coils
02:20 PM Tom_L: yeah i have to clean the AC coils once a year because of that
02:21 PM CaptHindsight[m]: grey lint that looks weavable
02:21 PM Tom_L: lots of cottonwood trees around here
03:13 PM perry_j1987: noticing the saddle rock on direction change on this cnc lathe
04:14 PM perry_j1987: quiet in here today
04:15 PM Tom_L: IS THIS BETTER!?
04:16 PM perry_j1987: lol
04:17 PM perry_j1987: what are you working on today
04:18 PM Tom_L: a couple tacos
04:18 PM perry_j1987: nice
04:18 PM perry_j1987: i am trying to figure out why this lathe's saddle seems to rock
04:18 PM perry_j1987: when you change directions in Z
04:19 PM CloudEvil: Added relaxation?
04:19 PM roycroft: i finally finished printing postcards
04:19 PM roycroft: i now understand why the same os and the same software behaves differently on different machines
04:19 PM roycroft: libreoffice uses java for some of its crap
04:20 PM roycroft: so there's an inherent wildcard
04:20 PM roycroft: anyway, it's 2pm, and my meeting is at, so i finished with 5 hours to spare
04:21 PM roycroft: meeting is at 7, rather
04:58 PM perry_j1987: nice
05:05 PM unterhausen: the pi4 from the buildbot said something about it being marked too old, that's to keep it from updating?
05:14 PM Tom_L: shouldn't be
05:14 PM Tom_L: what version installed from the iso?
05:19 PM XXCoder: cool, damascus steel https://youtu.be/KIC8NTsq9L0
05:19 PM Tom_L: unterhausen, did you start with the 2.8.1 pi4 img?
05:22 PM skunkworks: OMG - debian xfce finally has alt-t for terminal..
05:23 PM skunkworks: out of the box
05:26 PM roycroft: i just saw that video yesterday, xxcoder
05:27 PM XXCoder: nice
05:27 PM roycroft: he made a nice pattern using that hex bar
05:27 PM XXCoder: its not a subbed channel for ne
05:27 PM XXCoder: might sub bit
05:29 PM XXCoder: nice indeed
05:34 PM XXCoder: roy i guess guy never speaks?
05:37 PM JT-Shop: no, but sure is loud when the furnace is going
05:37 PM XXCoder: im not worried about envorment noises :)
05:37 PM XXCoder: just noticed that none of videos is captioned so wonder if guy ever spoke
05:37 PM JT-Shop: I've not heard a word
05:38 PM JT-Shop: interesting change of tools as he progresses
05:38 PM _unreal_: so just got home
05:39 PM _unreal_: hell of a day. went to rapids water park with my daughter.
05:39 PM _unreal_: went to the beach. got a ton of shells
05:39 PM XXCoder: yeah
05:39 PM XXCoder: new one, he uses bandsaw to cut block, but i chose random earlier video and he just grind cut ends off
05:40 PM XXCoder: tha one was year ealier
05:40 PM _unreal_: just got back to town. stopped into starbucks ordered a cap..chini for me got two one free do to a "fuck up????" hehe OH WELL
05:43 PM JT-Shop: https://gnipsel.com/images/wood-working/saw-stop/saw-cabinet-28.jpg
05:44 PM Tom_L: what type of finish is that?
05:45 PM Tom_L: oil, varnish, urethane...
05:46 PM JT-Shop: tried & true varnish oil
05:46 PM JT-Shop: first coat
05:48 PM JT-Shop: standoffs finally showed up at the mail box... after it gets too hot to be at foxy I'll be screwing standoffs
05:53 PM Tom_L: you should make an automated standoff loader
05:54 PM Tom_L: as many things as you've automated in your time...
05:54 PM JT-Shop: not enough volume
05:57 PM JT-Shop: https://www.blackanddecker.com/products/power-tools/portable-power-tools/screwdrivers/lithium-screwdriver-with-compactfit-technology/li3100
05:57 PM JT-Shop: I have and older version of that to assemble with
05:57 PM * JT-Shop wanders over to the grill to fire it up
06:03 PM unterhausen: Tom_L I took the link off the webpage and it says 2.8.1 pi4
06:03 PM unterhausen: the thing inside it says it was made in january of 2021
06:09 PM Tom_L: and it doesn't work?
06:16 PM solarwind: I bought a very cheap used trailer but it has no floor boards
06:16 PM solarwind: Otherwise in good condition
06:17 PM solarwind: Should I make the deck out of plywood or wood boards?
06:18 PM Tom_L: wood would be easier/cheaper to replace as needed
06:25 PM solarwind: Tom_L which type of wood? Plywood or just long boards?
06:26 PM Tom_L: boards
06:27 PM solarwind: Ok thanks
06:35 PM unterhausen: It boots fine, but there is some error message about not updating
06:35 PM Tom_L: i'm making an image to test
06:36 PM Tom_L: probably take a few to finish
06:37 PM Tom_L: what i think i did was uninstall the lcnc version on it then install from that deb i downloaded
06:37 PM Tom_L: is the version on that iso a "pre" version>
06:37 PM Tom_L: ?
06:38 PM Tom_L: i get an error that the zip is corruct
06:38 PM Tom_L: tried 2x
06:40 PM Tom_L: trying it anyway
06:42 PM unterhausen: file name is linux-2.8.1-pi4.zip at the end of the install, it says it needs to update and then it says it can't
06:43 PM Tom_L: no i know that but when you start linuxcnc what version is it?
06:43 PM Tom_L: did you download the .deb file as well?
06:46 PM Tom_L: booting..
06:48 PM unterhausen: no, it was getting late and I didn't get around to starting lcnc
06:49 PM Tom_L: are you near it?
06:49 PM unterhausen: i'm trying to get the monitor to display both computers
06:50 PM Rhine_Labs: Evening
06:51 PM unterhausen: heh, it's showing the full resolution of 43" monitorn in a 12"x8" space
06:55 PM unterhausen: okay, it says 2.8.1
06:55 PM unterhausen: which makes sense
06:56 PM Tom_L: and you downloaded the 2.8.2 deb file?
06:57 PM unterhausen: working on that
06:57 PM unterhausen: how do you uninstall what's there?
06:58 PM Tom_L: it is installed
06:58 PM Tom_L: oh
06:58 PM Tom_L: just a sec
06:58 PM Tom_L: misread..
06:58 PM unterhausen: web browser won't open for some reason
06:59 PM Tom_L: it's slow at best
06:59 PM Tom_L: but yeah i pulled it to a thumbdrive off my other pc
07:00 PM Tom_L: from the rasberry icon, Preferences -> Add/Remove Software
07:00 PM unterhausen: no, started it from a command line and it wants me to update the kernel
07:00 PM Tom_L: why?
07:00 PM unterhausen: no sandbox
07:00 PM unterhausen: let me check the kernel
07:02 PM unterhausen: working with 2 mice and keyboard is always awkward
07:04 PM unterhausen: I had the installer check for updates and it's doing its thing, so not sure what the previous issue on the initial setup was
07:04 PM Tom_L: if you get the gui follow the path to add reemove software
07:04 PM Tom_L: and type in linuxcnc
07:04 PM Tom_L: uncheck it
07:05 PM Tom_L: to remove it
07:05 PM Tom_L: then run the deb
07:10 PM Tom_L: yeah that works. i just did it
07:21 PM _unreal_: My newest listing https://www.etsy.com/BerinsETCHnENGRAVING/listing/1058331700/you-need-this-organizer-3d-print-this?utm_source=Copy&utm_medium=ListingManager&utm_campaign=Share&utm_term=so.lmsm&share_time=1629677247423
07:23 PM Tom_L: we are never that orgainzed
07:25 PM unterhausen: now it says it's 2.8.2
07:26 PM unterhausen: is 2.8.2 as detailed as the version number gets?
07:28 PM Tom_L: that's what i got with the deb
07:28 PM Tom_L: my previous install went a bit further but i don't recall the steps i took
07:28 PM Tom_L: i think they were the same
07:29 PM Tom_L: could be how they packaged the deb on that one
07:29 PM Tom_L: the last one i did was a version prior to that
07:34 PM unterhausen: cool, now to hook up a mesa and see what happens
07:35 PM Tom_L: you will need to load some drivers
07:37 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/RPI4/
07:37 PM Tom_L: those are the latest configs for my rpi4
07:38 PM Tom_L: with the 7i80 card
07:39 PM unterhausen: I'm going to go hook it up to a little pc because picture in picture is infuriating
07:44 PM Tom_L: look at JT's page for setting up the eth0 on it. personally i would go with the alternate address of 10.10.10.xx and set up a static ip on the rpi for such
07:45 PM Tom_L: https://gnipsel.com/linuxcnc/uspace/rpi4-eth.html
07:45 PM Tom_L: i skipped a couple steps but add a static entry to the dhcpcd.conf
07:49 PM unterhausen: the wifi on the pi seems to be pretty good
07:50 PM Tom_L: yes
08:01 PM unterhausen: still can't open a browser, complains about kernel
08:02 PM Unter_pi: Tom_L how hard is it for you to run uname?
08:03 PM Unter_pi: looks old Linux linuxcnc 4.19.71-rt24-v7l+ #1 SMP PREEMPT RT Fri Jan 1 21:15:16 GMT 2021 armv7l GNU/Linux
08:10 PM unterhausen: I have to build mesaflash?
08:12 PM unterhausen: okay, seems to run if I had a mesa card installed
09:00 PM unterhausen: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/RPI4/
09:04 PM unterhausen: so I get the hostmot2 files from mesa?
09:15 PM unterhausen: latency on the pi is good, irc not so much
09:18 PM Tom_L: unterhausen, i put the rpi away already
09:20 PM unterhausen: that's fine, I'll figure out the kernel later
09:20 PM unterhausen: browser works without a sandbox, I misspelled sandbox
09:21 PM Tom_L: it should be set already
09:21 PM Tom_L: or are you just wondering what ver it is?
09:21 PM unterhausen: the browser complains about the kernel, I was wondering if there was a newer kernel
09:21 PM Tom_L: i'm not aware of one
09:28 PM unterhausen: well, looks like I managed to hose my wifi
09:29 PM unterhausen: on the pi
09:29 PM unterhausen: by adding a static address for eth0
09:38 PM Tom_L: shouldn't have
09:41 PM Tom_L: seems you got it back
09:46 PM unterhausen: I couldn't see an error in dmesg
09:46 PM Unter_pi: but I commented out the eth0 lines in the config file and now it works
09:47 PM Unter_pi: I seem to remember having some such problem on the PC,but I don't remember what I did
09:48 PM Tom_L: you can try doing it from the gui
09:48 PM Tom_L: right click on the wireless icon and edit it there
09:49 PM unterhausen: the problem is in dhcptd.conf when I edited it
09:49 PM unterhausen: without the filename misspelled
09:50 PM unterhausen: I think that the examples don't have cr/lf at the end and you have to hit enter
09:51 PM Tom_L: i dunno if i copy / pasted or typed it in
09:51 PM unterhausen: I'm pretty sure that's the problem, but we're about to find out
09:53 PM unterhausen: well, eth0 doesn't have an ip address, but wlan0 works
09:54 PM Tom_L: hmm
09:55 PM unterhausen: I suppose I should relearn how to use grep on dmesg
09:56 PM unterhausen: is it just that there is no cable?
09:56 PM Tom_L: it could be
09:56 PM Unter_pi_: two errors, link is not ready, link is down
09:56 PM Tom_L: what ip did you use?
09:56 PM Unter_pi_:
09:56 PM Tom_L: ok
09:57 PM Tom_L: you need to jumper the mesa card for the alternate ip then
09:57 PM Tom_L: check the switches, they may be different than mine
09:57 PM Unter_pi_: okay
09:57 PM Tom_L: it's default alternate is
09:58 PM Tom_L: also, mesaflash should be installed with that deb now
10:00 PM Tom_L: mesaflash --device 7i80 --addr --readhmid
10:00 PM Tom_L: will give you a pin list
10:00 PM Tom_L: sub your boardname
10:03 PM unterhausen: okay, it was just the lack of a cable, it has the right ip address now
10:04 PM unterhausen: need to go find a 5v psu and hook up the mesa card
10:07 PM unterhausen: my guess is that it has the right firmware loaded
10:08 PM Tom_L: i clipped a usb cable and use that 5v for testing on the mesa card
10:21 PM unterhaus: I think our cable modem is flakey
10:22 PM XXCoder: check its temperate
10:22 PM XXCoder: not kidding, sometimes modem just gets hot
10:22 PM unterhaus: I actually have its replacement
10:22 PM unterhaus: made the mistake of buying an integrated modem router
10:24 PM unterhaus: won't do that again
10:27 PM unterhaus: I should have swapped stuff out when the family was at the beach
11:15 PM solarwind: So 240V circuit breakers are cheap and available everywhere. What about 480/600V circuit breakers?
11:15 PM solarwind: I realized circuit breakers make excellent disconnect switches in general
11:16 PM solarwind: Like general purpose on/off with the bonus of over current protection
11:25 PM roycroft: circuit breakers usually are not rated for as many on-off cycles as power switches
11:25 PM roycroft: personally, i really like to use magnetic switches with overload protection on my machines
11:25 PM solarwind: magnetic switches as in contactors?
11:26 PM solarwind: Or reed switch?
11:27 PM roycroft: https://www.grizzly.com/products/grizzly-5-hp-magnetic-switch-single-phase/t20551
11:27 PM roycroft: this type
11:28 PM roycroft: besides having overload protection, they have the critical feature of always being in the off state when power is first provided to them
11:28 PM roycroft: such as when power is restored after an outage
11:28 PM solarwind: Ah! I have one of those. I replaced that entire mechanism with a VFD and put it on a shelf somewhere
11:29 PM solarwind: It is indeed a contactor
11:29 PM roycroft: most of mine are made by teco
11:29 PM roycroft: yes, a contactor with a thermal overload switch
11:30 PM roycroft: and for the teco ones, you can get the thermal overload switch separately, and dial it in to the correct current for your device
11:30 PM roycroft: so the switch mechansim can be redeployed to a new device with a different current rating by just changing that one component
11:30 PM solarwind: Yeah the one I have that came with my mill is adjustable as well
11:31 PM roycroft: i just don't want a machine to ever turn itself automatically when power is restored
11:31 PM roycroft: i'm funny that way, i guess
11:32 PM solarwind: I think all VFDs do that naturally
11:32 PM roycroft: yes, vfds do that universally, i think
11:32 PM roycroft: but not all my machines have vfds
11:36 PM roycroft: most of those mag switches can handle 3 phase power
11:36 PM roycroft: but not high voltage 3 phase, necessarily
