01:16 AM Deejay: moin
02:27 AM Loetmichel: *giggle* i have two interns from school at the moment. Showed the kids how to solder. Used my finger to clean the sodering típ like always... "Oh, and by the way: YOU use the damp sponge in the holder for this please, i dont want to explain to our parents why you have burns!" Kid: "Yeah, i wouldnt touch a 310°C metal anyways." :)
02:27 AM XXCoder: lol
02:27 AM XXCoder: you got finger of steel
02:29 AM Loetmichel: 40+ years of training. you'll get used to it eventually
02:30 AM Loetmichel: funny thing was that it was totally automatic. Only noticed what i did afterwards, hence the warning to the kids
02:45 AM CaptHindsight[m]: Loetmichel: ping, which brand of copper coating do you have?
02:56 AM Loetmichel: ah!
02:56 AM Loetmichel: moment
02:57 AM Loetmichel: CaptainHindsight: Cramolin(r) EMV-Lack (EMILAC)
02:58 AM Loetmichel: Artikel number: 1241411
02:58 AM Loetmichel: its from www.itwcp.de
03:34 AM CaptHindsight[m]: thanks
03:34 AM CaptHindsight[m]: https://repository.qtpyvcp.com/repo/linuxcnc_debs/ LCNC 2.9 debs for Debian 11
03:36 AM CaptHindsight[m]: Surface resistance < 0,5 Ohm/mm2
03:36 AM CaptHindsight[m]: bei 0,25 µm film thickness
03:36 AM CaptHindsight[m]: thin stuff
03:36 AM CaptHindsight[m]: https://www.cramolin.de/product-1241411-en.html
03:38 AM CaptHindsight[m]: I tried building LCNC 2.9 on Sid and the same problem
03:39 AM CaptHindsight[m]: so it's more than just po4a issues
03:39 AM CaptHindsight[m]: I haven't tried installing those debs yet on Sid
03:40 AM CaptHindsight[m]: spent the day migrating a dev system to Deb 11
03:40 AM CaptHindsight[m]: I'll clone it and update it to Sid and see what breaks
03:41 AM CaptHindsight[m]: and try installing to a clean Sid system
03:43 AM Loetmichel: CaptainHindsight: yep. that stuff
04:24 AM travis_farmer: G'Morning
04:44 AM Tom_L: morning
04:57 AM john__: morning
04:58 AM Tom_L: did you get sserial to work?
05:02 AM XXCoder: geez thats massive split
05:02 AM XXCoder: that or matrix disconnected
05:03 AM travis_farmer: lots of people evacuating.... was there a tornado warning i missed??? ;)
05:03 AM XXCoder: nah probably a nuke
05:04 AM -!- #linuxcnc mode set to +v by ChanServ
05:04 AM JT-Cave: didn't work on it yet, got home kinda late yesterday
05:10 AM JT-Cave: it will create working outputs still need to fix inputs and fix loading the ini
05:22 AM Loetmichel: XXCoder: they should buy the tech of the company i work for... EMP-Proof :D
05:24 AM travis_farmer: must be the bridge just opened...
05:38 AM travis-farmer is now known as travis_farmer
05:39 AM pere: any spanish speaking individual present?
05:42 AM travis_farmer: it would seem that the IRC - Matrix - Discord bridge is a bit unstable at the moment...
05:44 AM pere: travis_farmer: bungee-joining. :)
05:45 AM travis_farmer: yeah, it seems to be going in and out
05:52 AM pere: It would be great if someone who knew spanish could go through the strings marked for editing in <URL: https://hosted.weblate.org/projects/linuxcnc/linuxcnc-docs/es/ > and review the translations for correctness.
05:53 AM travis_farmer[m]: Hmm, does the bridge work? my discord self has not re-joined IRC yet...
05:54 AM travis_farmer: well that was obnoxious...
05:56 AM pere: hard to keep a conversation going with so much join/leave-noise in the channel.
05:57 AM travis_farmer: yes it is
05:57 AM travis_farmer: i only know enough spanish to get me into a LOT of trouble... ;)
05:59 AM pere: While my level of Spanish would not even help me get out of trouble. :)
05:59 AM travis_farmer: years ago, i have a Cuban friend. all i know is "O'ye loco" (forgive the spelling)
05:59 AM travis_farmer: had, not have
06:00 AM pere: which I would guess means crazy bastart, and I understand how it could get you into trouble. :)
06:01 AM travis_farmer: i thought it meant "hey, crazy!"...
06:05 AM pere: you are probably more correct than me, as I can barely say hello in spanish.
06:05 AM travis_farmer: hola
06:05 AM travis_farmer: i learned that on Sesame Street ;)
06:12 AM pere: In Norwegian: Hei or Hallo. Now you know Norwegian too. :)
06:12 AM travis_farmer: lol
06:15 AM pere: btw, any of you know if the real time properties of a Raspberry Pi is better than a desktop motherboard?
06:16 AM travis_farmer: i have heard there are issues, but don't hold me to it
06:16 AM travis_farmer: i think some have had limited success
06:19 AM pere: travis_farmer: what kind of computer are you using with LinuxCNC?
06:20 AM travis_farmer: i have a Dell PowerEdge R200 rack mount server that i am using. it is less than ideal, but seems to be working for now
06:22 AM travis_farmer: were you planning on using parallel port control, or a Mesa board?
06:23 AM pere: I am using ethernet to a mesa board.
06:23 AM travis_farmer: ok, i was just going to say, the Dell R200 has no parallel ports, IIRC
06:24 AM pere: looking for a permanent computer, currently testing various ones and found a desktop that is working fairly well. but I want a smaller form factor.
06:24 AM pere: A 1U rack server seem way overkill...
06:24 AM travis_farmer: yeah, but i had it on hand, and it works, mostly
06:25 AM travis_farmer: i tried an Asus motherboard, but it failed miserably. it is really a trial and error kind of thing
06:27 AM travis_farmer: when i mount my Dell R200, i plan on building a vertical mount enclosure for it, so it takes less space
09:03 AM F4HVX[m]: Hello there !
09:05 AM F4HVX[m]: I noticed a problem on miled face, on a newly build cnc router : I get small step every two tool path, I dont understand why it's not on every path, any advices ?
09:06 AM ZincBoy[CAON][m]: Step in what axis? Picture of what is happening?
09:09 AM F4HVX[m]: https://hysope.ynh.fr/nextcloud/s/iGq6C3t52tHaAmm
09:09 AM F4HVX[m]: 5mm tool, you can see a litlle "step" every two path
09:09 AM ZincBoy[CAON][m]: What is your toolpath overlap?
09:10 AM F4HVX[m]: there is none overlap
09:11 AM ZincBoy[CAON][m]: You need overlap. What you are seeing is the bit deflection and that is dependent on cut direction. I would use at least 20% overlap (80% cut width).
09:12 AM F4HVX[m]: but why is it on every two path, not on each path ?
09:12 AM F4HVX[m]: oh I think I understand !
09:13 AM ZincBoy[CAON][m]: Because your are cutting back and forth in a zig-zag tool path. Because of the tool rotation, it pulls one way on left and the other on right. So you get some overlap between one pair and negative overlap on the other.
09:14 AM F4HVX[m]: I will add more screw to the spindle mounting to lower the deflection and add overlap
09:14 AM F4HVX[m]: thank you for your very clear explanation
09:16 AM ZincBoy[CAON][m]: You won't be able to eliminate the deflection. It is just something to work with. Even my 6 ton machine has deflection that needs to be compensated. The other way is to do a light finishing pass to clean things up. The light cut will also minimize deflection.
09:24 AM F4HVX[m]: this machine is not totaly finished, I wanted to test everything quickly, so I havent fully screwed the two X axis prismatic rail, only 3 screw on each (each side and middle) so I guess if I put all the screw it will be a lot better
09:24 AM F4HVX[m]: (this is a small machine)
11:57 AM travis_farmer: pretty quiet in here...
11:59 AM roycroft: shh - we're hunting wabbits
12:00 PM travis_farmer: lol
12:00 PM * travis_farmer heads out to workshop...
12:20 PM MrSunshine_ is now known as MrSunshine
12:34 PM CaptHindsight[m]: pere: finding a suitable PC for servo threads should be pretty easy (Mesa over Ethernet)
01:21 PM -!- #linuxcnc mode set to +v by ChanServ
01:50 PM CaptHindsight[m]: XXCoder: discord bot looks stuck for the past few hours
01:50 PM XXCoder: yeah
01:51 PM * travis_farmer returns from the sweaty workshop...
01:52 PM CaptHindsight[m]: travis_farmer: are the floors slippery?
01:53 PM XXCoder: lately 3d printing have discovered what cnc machinists have known for while... toolchangers is good lol
01:53 PM travis_farmer: no, wooden floors in this shop
01:54 PM XXCoder: example https://www.kickstarter.com/projects/bigbrain3d/swapper3d
01:56 PM travis_farmer: XXCoder: looks expensive and complicated... ;)
01:56 PM XXCoder: yeah.
01:56 PM XXCoder: its real multitool though, so you can use different plastics like pva for supports and pla
01:57 PM travis_farmer: yeah, but $8K ?
01:57 PM XXCoder: 8k?
01:57 PM XXCoder: nah iots 311 usd
01:58 PM travis_farmer: oh, the $8k was the dev funding they needed, ok
02:02 PM CaptHindsight[m]: I told everyone how to get around that 10 years ago
02:03 PM CaptHindsight[m]: better way is just add the color to white or clear filament as you print
02:08 PM CaptHindsight[m]: and not like that printer that used a TIJ ink cartridge
02:10 PM CaptHindsight[m]: https://www.xyzprinting.com/en-US/product/da-vinci-color
02:12 PM XXCoder: yeah
02:12 PM XXCoder: not always possible, and it dont cover all color possibilities]
02:14 PM CaptHindsight[m]: CMYM+W
02:14 PM CaptHindsight[m]: * CMYK+W
02:15 PM CaptHindsight[m]: no metallic's,florescent's, etc etc
02:16 PM CaptHindsight[m]: s/florescent/ fluorescent/
02:17 PM XXCoder: yep. also no mixed plastics
02:18 PM CaptHindsight[m]: a printer with DRM!
02:18 PM XXCoder: well yeah ignored the olvious part.
02:19 PM CaptHindsight[m]: I forget how controlling some FFF printers are
02:19 PM XXCoder: also, it uses ink, which is way more expensive than blood at hospital rates
02:19 PM roycroft: https://roycroft.us/New_Cabinets/28_Finished_Drawer_Fronts.jpeg
02:19 PM roycroft: finally
02:19 PM XXCoder: thats awesome work indeed.
02:19 PM roycroft: and i hate it even more than before :)
02:19 PM roycroft: but i can live with it ofr a while
02:19 PM travis_farmer: looks very nice, very nice indeed!
02:20 PM roycroft: from a distance it looks ok
02:20 PM roycroft: replacing the drawer pulls would help a lot
02:20 PM roycroft: but installing the drawer fronts properly is what i really need to do
02:20 PM roycroft: i've already come up with some ideas about how i could reuse the existing drawer fronts if i end up replacing them
02:21 PM travis_farmer: they aren't properly installed now?
02:21 PM roycroft: but my goal right now is to get the job done so i can move on
02:21 PM roycroft: i gang cut them, and i did so in columns, not rows
02:21 PM roycroft: as a result they don't line up very well
02:21 PM roycroft: i did it the way i did it to save time
02:21 PM roycroft: i do think i did a good job on grain matching/flow, though
02:21 PM travis_farmer: Hmm, hardly noticed
02:22 PM travis_farmer: yes, the grain matches :)
02:22 PM XXCoder: honestly its not house drawers, id not care as long as drawers dont bang each other
02:22 PM roycroft: yeah, but some day a prospective customer may come to my shop
02:23 PM roycroft: that day is not going to happen with a cabinet that looks like that
02:23 PM travis_farmer: if it was me showing up, i would still like them
02:23 PM XXCoder: lol didnt think of that. faceplates can be moved later I guess
02:23 PM roycroft: but there's a decent chance i'll be leasing some shop space with a proper office and showroom before i bring customers in to look at things
02:24 PM travis_farmer: looks like a LOT of hard work setting them up
02:24 PM roycroft: in which case i would just move that cabinet
02:24 PM roycroft: it's not hard work, but it is tedious work doing it properly
02:24 PM roycroft: and as i've said before, i think this is the most drawers i've ever built for one project
02:25 PM travis_farmer: well, that is what i meant by hard work
02:25 PM roycroft: even back in the '80s, when i was building cabinets for a living, and had a bigger shop and better fixtures for handling the parts, i don't think i ever built a set of cabinets with 48 drawers
02:25 PM roycroft: usually there are half dozen drawers and a bunch of doors on kitchen or bathroom cabinets
02:26 PM travis_farmer: i think the most drawers i have done in a kitchen build was 16
02:26 PM roycroft: and that's a *lot*
02:26 PM roycroft: even for a big kitchen
02:26 PM travis_farmer: customer liked drawers, what can i say? ;)
02:26 PM roycroft: so do i, for this application
02:27 PM travis_farmer: and i used a router and jig to half-blind dovetail all the drawers. what a PITA
02:29 PM roycroft: i made these greene and greene drawer pulls for another project:
02:29 PM roycroft: https://roycroft.us/Drawer-Pulls/DrawerPulls2.jpeg
02:29 PM roycroft: i think those would look better on the cabinets i just installed
02:29 PM roycroft: they're lower profile, a bit sleeker
02:29 PM roycroft: the mortises are for ebony pegs
02:30 PM travis_farmer: yeah, they doo look better, if you can keep your pants from hooking on them as you walk by
02:30 PM roycroft: https://roycroft.us/Sander-Cabinet/Sander-Cabinet-4.jpeg
02:31 PM roycroft: there they are installed
02:31 PM roycroft: i hadn't finished the plugs yet in that picture
02:32 PM roycroft: i hate those drawers too :)
02:32 PM roycroft: it's another shop cabinet, and i just used baltic birch plywood for the drawer fronts
02:32 PM roycroft: i can't stand rotary sliced veneer
02:32 PM travis_farmer: perhaps you are just too critical of yourself ;)
02:32 PM roycroft: but that's not one i'm going to redo
02:33 PM roycroft: there's a small chance i'll pull those drawers and veneer a skin of ash on the outsides
02:34 PM roycroft: but i won't ever replace them, nor even add edge banding
02:35 PM roycroft: making those drawer pulls (the greene and greene ones) was the impetus for my plan to build an over/under cnc/conventional router table setup
02:35 PM roycroft: the length of the pull has to be proportional to the width of the drawer to look decent
02:36 PM roycroft: and the curves need to vary with length so that they look and feel decent
02:36 PM travis_farmer: understandable
02:36 PM roycroft: the result being that i need a set of jigs for every size drawer pull i want to make
02:36 PM XXCoder: travis paint ripper handles I hate those
02:36 PM roycroft: it would be trivial to make those jigs with a cnc router
02:37 PM roycroft: i don't think the greene and greene ones are a problem
02:37 PM roycroft: my shop is a very small, tight space, and i've brushed against those pulls on the sander cabinet countless times
02:37 PM roycroft: they're rounded at the ends, and have just never gotten in the way
02:38 PM travis_farmer: yes XXCoder, i have several pants that died due to bad drawer pulls. usually the single knob will do it
02:39 PM roycroft: i've seen some art deco pulls that are curved like those greene and green pulls, but terminate flush at the ends
02:39 PM roycroft: if snagging were a concern i could use pulls like that
02:40 PM roycroft: i'm pondering doing small production runs of nice, unique wooden drawer pulls and selling them as an income generator
02:40 PM roycroft: and a way to use up scraps
02:40 PM travis_farmer: snagging isn't a concern? what, do you wear spandex in the shop? ;)
02:40 PM roycroft: i wear carhartt jeans
02:40 PM XXCoder: overcomplicated. nude. ;) kidding
02:40 PM travis_farmer: lol, i was just joking ;)
02:40 PM * roycroft owns no clothing made of artificial fabrics
02:40 PM roycroft: cotton, linen, hemp, wool
02:41 PM travis_farmer: oh, man, i did not need that images in my head XXCoder
02:41 PM XXCoder: lol
02:42 PM roycroft: i have a few rayon shirts, and while rayon is technically a non-natural fabric, it is derived from wood and it breathes and otherwise behaves more like natural fabrics than plastic fabrics
02:42 PM travis_farmer: yeah, looks like the Discord bridge has passed on... it is no more... it has ceased to exist...
02:42 PM roycroft: i don't know how people can stand to wear clothes made of plastic
02:42 PM roycroft: they are so uncomfortable
02:42 PM XXCoder: I was big fan of bamboo clothes but they take so much treatments to turn into fiber suitable for clothes :(
02:42 PM roycroft: i have a couple bamboo tee shirts
02:43 PM * travis_farmer wears Carhart's as well
02:43 PM roycroft: but yeah, bamboo takes a lot of processing
02:43 PM XXCoder: it takes a lot more than basic cotton, so I just wont buy em till theres some new process
02:43 PM XXCoder: maybe you can think of a solution dunno
02:44 PM XXCoder: im fine with heavy chemicals if its fully closed loop
02:47 PM XXCoder: talking about pollution, seems one of first co2 capture plants just started
02:48 PM XXCoder: and theres scientists that made artifical fish that eats microplastics. lets see how successful that is?
02:48 PM roycroft: cotton does not require a lot of processing to make into fabric, but it's a very heavy drain on the environment
02:48 PM XXCoder: yeah. so much chemical sprays, and they often kill plants then plant again for double plant season
02:48 PM roycroft: it's a very very heavy feeder, and will deplete the soil quickly unless it's well-fed, and it's also a very thirsty crop, and requires heavy irrigation in most places
02:49 PM XXCoder: bamboo is basically inverse. its like grass, just need small amount of maintance to keep going
02:49 PM roycroft: yes
02:49 PM XXCoder: but turning into cloth...
02:50 PM roycroft: hemp also does not need much food or water, but requires a lot of processing
02:50 PM XXCoder: however, processing side? oppunity for making closed loops
02:50 PM roycroft: traditionally the processing is time-consuming and labor-intensive, but low impact on the environment
02:50 PM XXCoder: closed loops means much lower chemical use, virtually. even if you use whole giant vats of dangerous chemicals
02:53 PM XXCoder: anyway yeah cotton sucks as farm product
03:02 PM XXCoder: not bridge fault this time

03:15 PM travis_farmer: what the heck???
03:15 PM roycroft: nice army base you have there, president erdogan
03:15 PM roycroft: it would be a shame if anything happened to it
03:17 PM XXCoder: interesting to see other side of split convos lol (via discord)
03:18 PM travis_farmer: something fishy going on here...
03:18 PM XXCoder: travis irc servers having some problems
03:19 PM travis_farmer: i gathered ;)
03:19 PM XXCoder: and bridge is not handling it quite well. lol
03:19 PM XXCoder: bridge users all are on single server, so when split happens, boom
03:19 PM travis_farmer: all Putin's fault ;)
03:20 PM CaptHindsight[m]: and it's not a problem if you feel that you are better than everyone else and deserve your riches and power because you are better of course
03:20 PM CaptHindsight[m]: wow i haven't even heard any of his new stuff from the past 20 years
03:21 PM xxcoder[m]: hmm
03:21 PM CaptHindsight[m]: https://www.reddit.com/r/pics/comments/vinu44/weird_al_and_his_mentor_dr_demento_1976_and_this/
03:21 PM roycroft: i haven't heard a lot of it
03:21 PM roycroft: i'm not a huge fan of his
03:21 PM roycroft: but he's funny, and a friend of mine wanted to see him, so i thought it would be fun
03:22 PM roycroft: sadly, my friend had an accident a month ago and broke his leg and elbow in multiple places
03:22 PM roycroft: he is currently in a rehab facility, and will not be able to attend
03:22 PM roycroft: but i'm still going to go
03:25 PM CaptHindsight[m]: reading through the comments it looks like kids today will not know what it's like to have to hope for good reception at night to get broadcasts from afar
03:26 PM roycroft: what do you mean?
03:26 PM roycroft: does the wifi go down at night or something? :)
03:29 PM XXCoder: radio
03:29 PM * roycroft was making a joke
03:30 PM XXCoder: ah lol
03:30 PM roycroft: and specifically, am radio is what he was talking about, i suspect
03:31 PM XXCoder: :)
03:33 PM * JT-Shop2 ponders how to make an edge band that overlaps the top and can expand and contract...\

03:38 PM XXCoder: texas is a country of its own
03:40 PM roycroft: well it wants to be one again
03:40 PM Rab: We're gonna build a wall!
03:40 PM roycroft: maybe we should let it secede
03:40 PM roycroft: as long as we get to keep austin and there's a rail and road corridor from the united states to austin
03:41 PM * roycroft thinks people just need to learn how to be nice to each other again, and then all this silly talk about civil wars and secession will go away
03:43 PM CaptHindsight[m]: happy to be nice to them and let them leave as well
03:43 PM travis_farmer: glad i live in Maine :)
03:43 PM XXCoder: year of assisting people to move to, or from, texas
03:44 PM CaptHindsight[m]: travis_farmer: but you face the Canadian threat
03:44 PM CaptHindsight[m]: and they speak French
03:44 PM travis_farmer: invasion from canada? seems low risk at this point... ;)
03:46 PM CaptHindsight[m]: poutine and Indian wars
03:46 PM CaptHindsight[m]: much gravy was spilled
03:49 PM roycroft: we (the usa) had a war with canada in 1859
03:49 PM roycroft: a pig was shot and killed
03:49 PM roycroft: it's funny how in europe it takes shooting an archduke to start a war, but here in north america a mere pig can be the cause
03:49 PM CaptHindsight[m]: might have deserved it
03:50 PM CaptHindsight[m]: https://www.thecanadianencyclopedia.ca/en/article/pig-war
03:51 PM roycroft: canada wasn't really a sovereign nation until 1867, so technically it was another war with england
03:51 PM CaptHindsight[m]: Canadian propaganda
03:51 PM roycroft: i'm sure our friends to the north see it differently to how we see it

04:13 PM mrec: ew a lathe bug G1 X1.5 F20 is skipped before M61 Q1/G43 H1 however if I put a comment in between it's okay it seems
04:15 PM JT-Shop2: hmm maybe a 1/4" strip of red oak, paduk, red oak or red oak, purpleheart, red oak...
04:16 PM roycroft: red oak is nice for firewood :)
04:17 PM JT-Shop2: and I used a lot for firewood, making a top for an egg drawer the top is small pieces of red oak glued up into a slab
04:18 PM JT-Shop2: https://gnipsel.com/images/wood-working/table-top/table-top-10.jpg
04:18 PM XXCoder: nice
04:18 PM JT-Shop2: It will be like that but with a 3/4" wide band and I'm thinking of adding an accent piece in the middle
04:19 PM JT-Shop2: https://gnipsel.com/images/wood-working/table-top/mobile-table-06.jpg
04:19 PM roycroft: i've been using ash a lot lately, but i like white oak quite a bit
04:19 PM JT-Shop2: that's the finished table top and refinished bottom parts
04:19 PM roycroft: but red oak just reminds me of the 1980s, shag carpeting, and appliances that are either avocodo green or mustard yellow
04:19 PM JT-Shop2: I have quite a bit of white oak
04:19 PM roycroft: those are not reminders i enjoy
04:20 PM JT-Shop2: I think my tables look nice
04:20 PM roycroft: yes, your tables do not look like the 1980s
04:20 PM roycroft: this is my problem, not yours
04:20 PM JT-Shop2: lol
04:20 PM XXCoder: 1980s was horrible era for me too lol
04:20 PM JT-Shop2: O
04:21 PM JT-Shop2: I'm thinking of using paduk for the center of the band, I think purpleheart is too dark
04:21 PM roycroft: you don't use wide, flatsawn boards with heaps of cathedraling
04:21 PM roycroft: padouk gets rather dark over time
04:21 PM roycroft: it is that nice, bright orange when it's freshly machined, but it turns a lot darker and browner over time
04:21 PM JT-Shop2: dark as walnut?
04:22 PM roycroft: usually not that dark, but it can get fairly dark
04:22 PM roycroft: there are several varieties of padouk
04:23 PM JT-Shop2: I also have some zebra wood but don't know if I want to use that for this but it would look nice as the whole band board
04:24 PM JT-Shop2: mine says african padauk
04:31 PM roycroft: well if you have the padouk go for it
04:31 PM roycroft: it will be fine
04:32 PM roycroft: i'm just saying it will get darker over time
04:32 PM roycroft: cherry would be nice but it, too, will darken somewhat over time
04:37 PM JT-Shop2: no cherry in stock... aspen and mahogany
04:37 PM JT-Shop2: I think I'll make a test piece to see what it looks like
04:39 PM Tom_L: anything new to test?
04:41 PM JT-Shop2: sserial
04:41 PM Tom_L: what does it do now?
04:41 PM Tom_L: the pin list?
04:41 PM JT-Shop2: "should" work as advertised
04:42 PM JT-Shop2: creates a working configuration and loads it back up now
04:42 PM Tom_L: i'll grab it here in a bit
04:42 PM JT-Shop2: ok, thanks
04:43 PM roycroft: mahogany would be nice
04:43 PM roycroft: but i'm rather partial to mahogany
04:45 PM Tom_L: you don't see much of it nowdays
04:45 PM Tom_L: that or walnut
04:46 PM Tom_L: red or brown?
04:46 PM JT-Shop2: hmm mahogany for the whole piece might just be what I'm looking for, just a bit darker than the red oak
04:47 PM Tom_L: woopsie
04:48 PM Tom_L: a program error occurred in request.py line 649 404 not found :)
04:48 PM JT-Shop2: I have some walnut but I think it would be too dark except for maybe a 1/8" wide accent strip
04:48 PM JT-Shop2: wonder that request.py is?
04:49 PM Tom_L: trying to dl the deb
04:49 PM Tom_L: can't find one aparently
04:49 PM JT-Shop2: I bumped the version...
04:49 PM Tom_L: i clicked dl deb
04:49 PM JT-Shop2: hmm I need to check for that and offer the latest one
04:49 PM JT-Shop2: I assumed so
04:49 PM Tom_L: :)
04:50 PM JT-Shop2: but the last deb is still there
04:50 PM Tom_L: it can't see it
04:50 PM Tom_L: i guess
04:50 PM JT-Shop2: might be an internet issue
04:50 PM Tom_L: and i dumped my old one
04:51 PM Tom_L: gnipsel works
04:51 PM JT-Shop2: https://github.com/jethornton/mesact
04:51 PM JT-Shop2: 0.6.5 is the latest and I just remembered I didn't change it in the main py file :(
04:52 PM Tom_L: ok i got it the _hard_ way :)
04:52 PM JT-Shop2: two mouse clicks instead of one?
04:53 PM Tom_L: error reading package list
04:55 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/Mesact_install.png
04:57 PM Tom_L: i get that on the .4 version too
04:58 PM JT-Shop2: I've never seen the reinstall for apt-get but I don't use apt-get, I use apt install
04:58 PM Tom_L: i thought it was the same
04:58 PM Tom_L: shows what i know
04:58 PM JT-Shop2: but only if gdebi is not installed
04:58 PM roycroft: i thought apt-get was deprecated
04:58 PM JT-Shop2: that's kinda what I thought
04:59 PM XXCoder: apt and apt-get should both always work
04:59 PM XXCoder: apt-get sometimes redirected to apt
04:59 PM * roycroft wonders why one would type apt-get when apt would suffice
04:59 PM roycroft: that's over twice the typing for the same thing!
05:00 PM JT-Shop2: in the infamous quote from Jim Mora coach of the saints football team "shoulda, woulda, couda"
05:00 PM Tom_L: same thing with gdebi
05:00 PM roycroft: well, it is 3 o'clock
05:00 PM XXCoder: im not certain but I think apt was orginal, apt-get was upgraded fork for while, then apt updated
05:00 PM * roycroft heads out to the fair
05:00 PM JT-Shop2: I'll see what's up in the mornin
05:00 PM JT-Shop2: g
05:00 PM XXCoder: could be wrong however
05:00 PM * Tom_L puts his toys away
05:00 PM roycroft: hopefully the work i do today will be the end of it
05:01 PM * JT-Shop2 did find 4 strips of black walnut that would be perfect
05:01 PM XXCoder: roy whats up with gst3d?
05:28 PM * JT-Shop2 has the strips prepped for the edge banding so time to call it a night
05:31 PM coralgoat: I am looking into building a CNC router from an open source design.
05:31 PM coralgoat: I have found some open source CNC designs.
05:31 PM coralgoat: I have decided that I am not going to build one of these:
05:31 PM coralgoat: <https://www.maslowcnc.com/> - the example pictures only show wood parts being made. I want to build aluminum parts.
05:31 PM coralgoat: MPCNC <https://docs.v1engineering.com/mpcnc/intro/> - but <https://inv.vern.cc/watch?v=68ohaPYyiDA> says that the MPCNC is not a free design (creative commons non commercial) and the project lead of MPCNC is hostile toward free design derivatives of their work.
05:32 PM coralgoat: The ones I am thinking about are:
05:32 PM coralgoat: https://indystry.cc/indymill/
05:32 PM coralgoat: https://indystry.cc/2020/07/06/how-to-build-3d-printed-dremel-cnc/
05:32 PM coralgoat: Openbuilds <https://docs.openbuilds.com/doku.php?id=docs:machines:comparison>
05:32 PM coralgoat: Any other interesting open source CNC router designs I have missed and should be looking at?
05:32 PM coralgoat: I have only taken a brief cursory look at openbuilds. They have several different machine designs. They are using the creative commons by share alike license. Looking at just one of the machines there is a detailed step by step build video.
05:33 PM CaptHindsight[m]: look at all of them, try building, how you learn
05:34 PM CaptHindsight[m]: cutting aluminum rapidly requires a more rigid machine
05:35 PM CaptHindsight[m]: coralgoat: are you interested in milling or engraving aluminum?
05:37 PM CaptHindsight[m]: CaptHindsight: for milling you must consider https://www.khanacademy.org/science/physics/forces-newtons-laws/newtons-laws-of-motion/a/what-is-newtons-third-law
05:38 PM coralgoat: I would like to be able to mill aluminum.
05:38 PM CaptHindsight[m]: then you need a machine frame stiffer than the aluminum that you will cut
05:40 PM coralgoat: CaptHindsight[m], thanks for pointing that out.
05:41 PM CaptHindsight[m]: Newton knew what he was talking about
05:42 PM CaptHindsight[m]: https://www.youtube.com/watch?v=4aBVAbfxLJw
05:42 PM roguish[m]: coralgoat: much, much stiffer. look up the difference between stiffness and strength. it will really help understanding
05:45 PM CaptHindsight[m]: wow there is so much wrongness here https://www.youtube.com/watch?v=q0RE-h1VDIg
05:53 PM JT-Cave: Tom_L, mesact deb installs just fine here...
05:55 PM roguish[m]: JT-Cave: used your gcode gen this morning to do some facing
05:55 PM JT-Cave: nice
05:56 PM roguish[m]: had to dink around a bit to get the depth right. not at the mill now, so I can't recall and explain everything I did.
05:56 PM JT-Cave: when you remember let me know
05:56 PM roguish[m]: sure thing
05:58 PM JT-Cave: Tom_L, download deb should get the latest one by default
05:58 PM JT-Cave: just looked at my code
06:48 PM Tom_L: i'll check
06:49 PM Tom_L: dl worked this time
06:50 PM Tom_L: installed this time
06:53 PM Tom_L: read ss pins this time
06:54 PM Tom_L: analog spindle on spindle tab doesn't require pid now
06:55 PM Tom_L: it did ask about an older version ini on loading
06:57 PM coralgoat: CaptHindsight[m], I had not thought of using epoxy.
06:58 PM coralgoat: roguish[m], thanks for that tip.
07:01 PM Tom_L: JT-Cave, sserial pins are assigned now.. config started with no mods this time
07:02 PM Tom_L: it would be cool if you could populate the tool table as part of the config
07:02 PM Tom_L: just a thought...
07:04 PM Tom_L: relay schematic is a plus :)
07:38 PM Thorhian[m]: Hey guys, I'm trying to learn about tool length offsets. I'm using M6 to load a tool (manual tool change). From there I use a 123 block on my machine table and put the tool right above it to a set distance using some shim stock. I then use the tool touch off button to set the offset. However, no changes seem to be permanent and don't save to my tool table. If I switch tools and switch back, G43 doesn't do anything (implying the offset
07:38 PM Thorhian[m]: hasn't been saved to the tool table). How should I do this properly in my current situation?
07:39 PM ZincBoy[CAON][m]: Does the tool table update? You should see the change in tool.tbl or what ever you defined.
07:39 PM ZincBoy[CAON][m]: Also, what GUI?
07:39 PM Thorhian[m]: Axis
07:40 PM ZincBoy[CAON][m]: You call T<number> as well as the M6 correct?
07:40 PM Thorhian[m]: Yes, and the Z coordinate in the table should be changing right?
07:41 PM ZincBoy[CAON][m]: Yes, the Z coordinate should update when the touch off is complete.
07:41 PM Thorhian[m]: It never changes.
07:43 PM Thorhian[m]: Does having the tool table GUI interfere with LCNC from updating that table?
07:44 PM ZincBoy[CAON][m]: Not in my experience. The tool table GUI does not keep the file open and you have to refresh to see any changes.
07:45 PM Thorhian[m]: That's what I thought.
07:45 PM ZincBoy[CAON][m]: I use gmoccapy so I am not familiar with the axis touch off behavior.
07:45 PM ZincBoy[CAON][m]: Does the Z DRO value change after touch off?
07:49 PM Thorhian[m]: Yes, but like I said, that change doesn't stick if I load another tool and perform another tool touchoff. If I got back to the first tool I did and load the offset for that first tool, Z DRO doesn't change.
07:49 PM ZincBoy[CAON][m]: What is the code you use to change tool?
07:49 PM Thorhian[m]: M6 Tn
07:50 PM ZincBoy[CAON][m]: That should be fine.
07:50 PM Thorhian[m]: G43 for loading the offset.
07:51 PM ZincBoy[CAON][m]: If you do a G10 L10 Pn Zheight does it update the table?
08:00 PM Thorhian[m]: I restarted the whole system, rehomed, and made sure to use m6 t10 g43 before doing the tool offset. It saved finally.
08:06 PM Thorhian[m]: And it worked on tool 11 without changing t10. Excellent.
08:09 PM Tom_L: you can use the axis gui to set the tools too
08:09 PM Tom_L: are you setting several at once or one at a time?
