03:39 AM miss0r: Glad to be back - thanks
04:50 AM lcnc-relay: <travis_farmer@> Morning
05:43 AM -!- #linuxcnc mode set to +v by ChanServ
05:53 AM JT-Mobile: morning
06:16 AM lcnc-relay: <sodakaustik@> morning!
06:16 AM lcnc-relay: <sodakaustik@> taper threading is such a pain
06:30 AM JT-Mobile: G33?
06:32 AM JT-Mobile: See the Integrators Manual for more information on spindle synchronized motion.
06:33 AM JT-Mobile: I combined that into one manual years ago
06:34 AM lcnc-relay: <sodakaustik@> i just have very specific needs, i have no issues using g33
06:36 AM JT-Mobile: are you using a program to generate the g33 code?
06:44 AM JT-Mobile: https://forum.linuxcnc.org/media/kunena/attachments/21542/npt_pipe_2020-06-21.ngc
06:48 AM JT-Mobile: https://forum.linuxcnc.org/lathe-subroutines-library/32895-pipe-threading?start=0
06:48 AM JT-Mobile: interesting post
11:32 AM lcnc-relay: <sodakaustik@> I wanna do it manually so that i can dial it in better
12:55 PM JT-Mobile: https://ibb.co/ZRPHHc8y
12:58 PM Tom_L: looks like a nice day for it
01:08 PM JT-Mobile: Yup, and a bit of a breeze too
01:29 PM xxcoder: https://youtu.be/ZspDqxx2MFY patent tool recreation
01:29 PM xxcoder: weird wrench
04:41 PM -!- #linuxcnc mode set to +v by ChanServ
04:41 PM JT-Mobile: fun day
04:47 PM lcnc-relay: <skunkworks8841@> neat!
04:48 PM JT-Mobile: https://youtu.be/YdJ0aonX1pU
04:49 PM JT-Mobile: may take a minute or so to process
04:53 PM xxcoder: thats cool
04:53 PM Tom_L: what's a good lap time?
04:54 PM JT-Mobile: I did 1.21 which is a good time
04:58 PM xxcoder: 1.21 days? ;)
04:58 PM xxcoder: I guess its minutes
04:58 PM JT-Mobile: 1 minute 21 seconds for a 1.6 mile lap
04:58 PM xxcoder: nice
04:59 PM lcnc-relay: <skunkworks8841@> lol - do you get a lot of instruction for brake points and turn in/outs?
04:59 PM Tom_L: little over 60 average?
05:02 PM JT-Mobile: skunk, I took a course for performance driving, the first time I drove at this track I followed someone one session
05:02 PM Tom_L: maybe closer to 80
05:03 PM JT-Mobile: the track has apex markers, turn in markers and other clues
05:03 PM JT-Mobile: 125 in the straight
05:04 PM JT-Mobile: so no instructions for this track
05:15 PM JT-Mobile: uploading a pdr
05:39 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/6FPTniyr4UBPwBa28
05:39 PM lcnc-relay: <skunkworks8841@> I think that is going to work
05:42 PM Tom_L: why do you need adjustable mounts on a tree house?
05:50 PM lcnc-relay: <skunkworks8841@> this is a 2 ft in diameter oak tree - I want the tree house to be totoally supported by the tree - I want struts making the triangles down to the tree from the edges - and I can level the whole thing.
05:53 PM lcnc-relay: <skunkworks8841@> that crap machines suprisinly well...
05:53 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/bbgUQ7qwB32gAJzv8
05:54 PM xxcoder: ah good, I see you made a lightsaber, jedi.
06:08 PM JT-Mobile: watch tree house masters for ideas
06:21 PM JT-Mobile: https://youtu.be/FEXbG-ooyp8
06:30 PM JT-Mobile: look close at the start a C4 went off the track
06:40 PM roycroft: treehouses absolutely need adjustable mounts
06:40 PM roycroft: they both grow and move
06:40 PM roycroft: the trees, that is
06:40 PM roycroft: hopefully not the treehouse
06:41 PM xxcoder: hey how are cats
06:41 PM roycroft: they survived the night
06:41 PM roycroft: folks go to bed early around here
06:41 PM roycroft: so the noise was done well before midnight
06:41 PM roycroft: unlike when i lived in eugene, where the fireworks would go on until the wee hours of the morning
06:42 PM xxcoder: saw some fireworks here
06:42 PM roycroft: anyway, they seem no worse for the stress from last night
06:42 PM roycroft: and last year the only fireworks i heard were on the 4th
06:43 PM roycroft: again, unlike eugene, where they'll be going off nightly for a few days
06:43 PM xxcoder: seeing fieworks is fnny. theres $513 fine for that
06:44 PM xxcoder: actually they allows it only on 4th now. interesting
06:44 PM roycroft: same here
06:44 PM roycroft: but that does not stop people from setting them off whenever they want
06:44 PM roycroft: actually, here they are permitted twice/year - on the 4th of july and on new year's eve
06:53 PM xxcoder: interesting
07:06 PM lcnc-relay: <skunkworks8841@> the monarch is awesome
07:06 PM lcnc-relay: <skunkworks8841@> it is running on a rpi4 - instead of the 5.. just takes a bit longer to boot
07:07 PM Tom_L: did you put the newest image on it?
07:07 PM Tom_L: 2.9.4
07:09 PM lcnc-relay: <skunkworks8841@> yes
07:10 PM lcnc-relay: <skunkworks8841@> that is what I ran the green machine for a bit. did have to run a 2ms base thread
07:10 PM lcnc-relay: <skunkworks8841@> the monarch is running a 1ms thread - but that is hal only.
07:11 PM lcnc-relay: <skunkworks8841@> pretty light weight...]]
07:15 PM Tom_L: my D525 runs a slower base thread as well
07:15 PM Tom_L: forget what atm
07:15 PM lcnc-relay: <skunkworks8841@> I bet..
07:16 PM lcnc-relay: <skunkworks8841@> I have been meaning to try the 5 on the green machine with the lastest image
07:16 PM Tom_L: 1.5 maybe
07:16 PM lcnc-relay: <skunkworks8841@> I think that should have no problem running 1ms
07:16 PM Tom_L: i have a 7i80 i can swap for the 7i90 on the mill for testing
07:16 PM Tom_L: has the same config
07:17 PM Tom_L: just change the mesa drivers
07:17 PM lcnc-relay: <skunkworks8841@> neat..
07:17 PM lcnc-relay: <skunkworks8841@> hugs mesa....
07:18 PM Tom_L: https://www.youtube.com/watch?v=g0OLIth_cOI
07:18 PM Tom_L: that's what that spaghetti was all about
07:19 PM Tom_L: that was an older image
07:22 PM lcnc-relay: <skunkworks8841@> neat
07:22 PM lcnc-relay: <skunkworks8841@> going to start storming here
07:22 PM Tom_L: that actually ran ok with a 1ms thread but i've had to slow it down for the newer versions
07:23 PM lcnc-relay: <skunkworks8841@> same - my old image from years ago ran 1ms
07:23 PM Tom_L: that being wheezy
07:23 PM lcnc-relay: <skunkworks8841@> but - it is what it is.
07:23 PM Tom_L: yup
07:23 PM Tom_L: good to know it's not just me then
07:24 PM lcnc-relay: <skunkworks8841@> I spent a good amount of time with kernel line testing but could not get it to run 1ms consistanly,,
07:25 PM lcnc-relay: <skunkworks8841@> with the latest image. (but - yes - it runs just fine with 2ms)
07:25 PM Tom_L: the 5 should have no problems
07:25 PM lcnc-relay: <skunkworks8841@> right - I was running a pretty fast base thread on it..
07:25 PM lcnc-relay: <skunkworks8841@> goofing around
07:27 PM Tom_L: on my rpi5 tests i never did get mesaflash to work with spi on the 7i90 but the spix driver seems to work fine
07:28 PM Tom_L: the guys running the rpi boards seem to be ok afik
07:28 PM lcnc-relay: <skunkworks8841@> I have always use ethernet
07:28 PM lcnc-relay: <skunkworks8841@> never played with spi
07:28 PM Tom_L: i'm using pp on the 7i90 still
07:28 PM Tom_L: but it will do spi
07:28 PM lcnc-relay: <skunkworks8841@> that is crazy
07:28 PM lcnc-relay: <skunkworks8841@> lol
07:29 PM Tom_L: so that's what i test with
07:29 PM roycroft: try spi with your own eye
07:29 PM lcnc-relay: <skunkworks8841@> lol
07:30 PM Tom_L: it was there so i had to try it
07:31 PM Tom_L: it's a pretty fast protocol actually
07:32 PM Tom_L: over a short distance
07:33 PM lcnc-relay: <skunkworks8841@> right - I think it is better than ethernet - not as much overhead
07:34 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Rpi5/spi_cable.jpg
07:34 PM Tom_L: therein lies the problem
07:35 PM Tom_L: that cable is near max length
07:35 PM Tom_L: so for a 7i90 to pc it wouldn't be practical
07:35 PM lcnc-relay: <skunkworks8841@> oops - I think I missed the chance to get back to the house without getting wet
07:35 PM Tom_L: i'm sure you can find a bucket
07:41 PM fywolfluff: well, here's a place I haven't been in a while! what's the current usability of cad+cam on linux? I need to make a motor mounting plate. It'll be a round clamp with mounting tabs cut out from alu plate. Is this something I can do yet without wanting to kill people?
07:41 PM fywolfluff is now known as fluffywolf
07:41 PM lcnc-relay: <skunkworks8841@> freecad.
07:41 PM lcnc-relay: <skunkworks8841@> I think that is your only option currently
07:42 PM Tom_L: hand code it. it's a flat pattern
07:42 PM fluffywolf: freecad fails that requirement. badly.
07:42 PM Tom_L: it's not that difficult compared to learning freecad etc
07:42 PM lcnc-relay: <skunkworks8841@> then - as tom said - by hand
07:42 PM fluffywolf: every time I use it, the people in #freecad insist I have to try the absolute latest version off their website because it's fixed all the bugs, but it hasn't fixed any of the bugs and crashes, does stupid shit, eats my parts, eats my saves files, and never ends up with a part.
07:43 PM lcnc-relay: <skunkworks8841@> lol
07:43 PM Tom_L: like i suggested....
07:43 PM Tom_L: and you might learn something along the way
07:43 PM lcnc-relay: <skunkworks8841@> I have used it off and on over the last few years.. I have even used cam.. it certainly has a learning curve - but not had those problems
07:44 PM Tom_L: both my kids competed for that in a contest with skillsusa
07:44 PM fluffywolf: yes, this part is mostly 2d, and I could code it by hand... but I really want to learn cad for future projects.
07:44 PM Tom_L: given a drawing you had to hand code the part
07:45 PM fluffywolf: cam is the next issue... is there any working cam yet? so far, heekscnc is the only program I've had generate a usable toolpath. nothing else could make even a simple toolpath. pycam had the notable exception of taking a lieral day before producing each useless output.
07:45 PM fluffywolf: literal
07:46 PM Tom_L: they say freecad cam works ok
07:46 PM Tom_L: i use an old commercial product for my needs
07:47 PM fluffywolf: I've tried to get a few commercial products working in wine, with no success... would probably need to use a VM.
07:47 PM roycroft: many folks have said here that freecad's cam workbench does what it is supposed tod o
07:48 PM Tom_L: the first copy i purchased was in DOS if that's any indication of it's age
07:48 PM Tom_L: but, gcode hasn't changed
07:49 PM fluffywolf: I'm probably going to end up manually making this part (the cnc mill is in pieces, with my shiny mesa boards sitting in a box on top of it for... gawd, way too many years), but I really want to get cad+cam working for bigger projects...
07:49 PM Tom_L: may need a cnc to use it on then
07:50 PM fluffywolf: well, it works, with the parallel breakout board that I set up before I got the mesa boards...
07:52 PM fluffywolf: ... which, along with the motor controllers, power supply parts, etc, is all in a big sketchy pile of wires sitting next to it, since I was going to build the enclosure to fit the mesa stuff...
07:56 PM fluffywolf: anyone figured out how to get a proprietary cad program working in wine? the "solidworks on linux" stuff on winehq is spam, with the scripts containing bugs that would prevent them from ever working, and fixing them does not cause working.
07:57 PM roycroft: i tried years ago
07:57 PM roycroft: i ended up buying a dedicated cad workstation that runs windows natively
07:58 PM roycroft: the whole concept of utilities like wine seems kind of silly
07:58 PM fluffywolf: every time I use windows, I always end up very angry. utterly awful user experience, every time without fail.
07:58 PM roycroft: especially in an age where we have freely-available hypervisor software that runs virtual machines at near raw iron speed
07:59 PM xxcoder: wine is amazing for some uses. like running programs too old to run on current windows
07:59 PM roycroft: i would not want to use windows as my primary operating system
07:59 PM xxcoder: theres new pc program thing, forgot name for it though
07:59 PM xxcoder: me either
08:00 PM roycroft: but for dedicated workstations such as i just described, there's usually very little direct interaction with the operating system
08:00 PM roycroft: so the os really doesn't matter much
08:01 PM fluffywolf: about a year ago I have freecad another serious try, wasted several days on it, couldn't manage to make even a simple part without running into bugs.
08:01 PM fluffywolf: s/have/gave
08:02 PM roycroft: lots of folks use it and do real work with it
08:02 PM roycroft: but if it doesn't work for you then i suggest you find something else and not use freecad
08:02 PM xxcoder: I havent really played with very recent 1.0 version but was great for me before even then. though like roy says if it doesnt work, it doesnt work for you
08:02 PM fluffywolf: one of the bugs corrupted my save file so it couldn't re-open the file it had just saved, losing all the work I'd tried so far, and that was when I gave up...
08:02 PM roycroft: i've found that it works decently, but has a very steep learning curve
08:03 PM roycroft: my main objection to it, for years and years, is that it did not have an official assembly workbench, and was therefor unsuitable for my needs
08:03 PM roycroft: but now it does
08:03 PM roycroft: and when i have the time to invest, i may start using it for real projects
08:03 PM xxcoder: yeah. was a surpise its new one, not one of 4 projects before
08:04 PM roycroft: that's why i had said for years that it doesn't matter that there are unofficial ones
08:04 PM xxcoder: also realthunder have finally been merged in I think
08:04 PM fluffywolf: looks like that was may 10th, 2024... I guess I should see if it's become less-buggy in the last 14 months. of course, I've been occasionally trying it for more than 14 years...
08:04 PM xxcoder: so improvements all around
08:04 PM roycroft: it needed the official one
08:04 PM fluffywolf: if it's still a 1GB appimage, won't be trying it for a day.
08:05 PM roycroft: fluffywolf: a lot of people have had problems with freecad, but this is the first time i have every heard anyone say that it's buggy to the point that multiple versions over a long period of time corrupt files such that they cannot be reopened
08:05 PM xxcoder: thats nice thing about freecad, its free to try, and if it dont work just remove and only cost is download and test time
08:05 PM xxcoder: roy I had that, but it was years ago with horrible 0.30 and 0.5 I think
08:05 PM roycroft: i can only think that you might be triggering some edge conditions that nobody else has
08:05 PM roycroft: i've had it happen as well
08:06 PM roycroft: but not consistently over several versions
08:06 PM fluffywolf: ... apparently I'm a bot and their wiki won't load. jesus fuck, they've managed to make it even worse. lol
08:06 PM roycroft: we'll i'll suggest again that you move on to something else
08:06 PM fluffywolf: at least it has a cute anime girl to show failing? lol
08:06 PM xxcoder: uh what
08:07 PM fluffywolf: roycroft: I have no idea what I'm doing, so I likely do things differently than skilled people (like the devs) do, and thus run into issues they do not.
08:07 PM roycroft: not all software works well for all people
08:07 PM xxcoder: tested download at freecad.org. seems ok
08:07 PM fluffywolf: xxcoder: the wiki has a "prove you're not a bot" thing before it loads.
08:08 PM * fluffywolf hasn't tried the download yet
08:08 PM xxcoder: ah I see the anime girl
08:08 PM xxcoder: loaded fine tho
08:09 PM fluffywolf: it decides I'm not a bot, but never shows any content, and repeats the anime girl if I reload the page...
08:09 PM roycroft: i just read the other day, and posted here, that lightburn (the laser software folks) are coming out with some cnc router software this summer that, while grbl oriented and able to directly control grbl-based machines, will support standard gcode-based machines as well, but cannot directly control them
08:09 PM roycroft: linuxcnc is on their list of officially supported platforms
08:10 PM roycroft: i would wager that you would find the lightburn product easy to use and will work well
08:10 PM xxcoder: hmm isnt both of those machine controllers? if so, I am unclear on what support means
08:10 PM roycroft: and it's going to be relatively inexpensive - i forget the exact cost, but $200 sticks in my mind as an approximate cost
08:10 PM Tom_L: i found a way to just buy commercial software and have it earn it's own keep
08:10 PM rdtsc: thought Lightburn dropped linuxcnc a year or so ago
08:10 PM Tom_L: far fewer headaches
08:10 PM rdtsc: err dropped linux
08:11 PM roycroft: what i mean by that, xxcoder, is that if you have a grbl-based machine you can talk directly to the machine with the lightburn software
08:11 PM xxcoder: ahh ok
08:11 PM roycroft: if you have a linuxnc-based machine you talk to the linuxcnc machine which talks to the router
08:11 PM roycroft: but i guess that's essentially the same thing
08:11 PM roycroft: as the grbl-based machine is the router with a built-in controller
08:12 PM fluffywolf: started the current dev build downloading... won't be trying it today due to 775MB download size.
08:12 PM roycroft: anyway, i'm just mentioning that it will soon be an option
08:12 PM roycroft: and the lightburn laser software runs on windows, macos, and linux
08:12 PM Tom_L: better than trying to download xilinx webpack :)
08:12 PM roycroft: i should think the router software woudl also support all three of those platforms
08:12 PM Tom_L: like 6gb?
08:12 PM Tom_L: i forget
08:12 PM fluffywolf: Tom_L: ouch. lol
08:13 PM fluffywolf: my theory is freecad works if you do the exact steps in the exact order than the devs/experienced users would do to create a part, but if you have no idea what you're doing and just try things, you run into about a million bugs that they never run into...
08:15 PM fluffywolf: I mean, I know it must work for someone, since there's shiny images online of parts people have made in it... but I managed to run into critical bugs once just following the exact steps in a youtube tutorial meant for an earlier version...
08:17 PM Tom_L: they need better testers
08:17 PM Tom_L: break it until you can't
08:17 PM Tom_L: then release it
08:17 PM fluffywolf: I get pissy too quickly to be a good tester.
08:17 PM roycroft: it took them 20 years to come out with version 1.0
08:18 PM roycroft: i think they had plenty of time to test :)
08:18 PM Tom_L: i don't have enough years left to wait for v2
08:18 PM Tom_L: and i'm not about to become a freecad tester
08:18 PM Tom_L: i'd just piss them off
08:19 PM roycroft: fluffywolf: https://millmagesoftware.com/
08:19 PM roycroft: you might sign up to be notified
08:19 PM roycroft: and maybe see if you can test a beta version in the meantime
08:20 PM Tom_L: more wonder wear
08:20 PM fluffywolf: is there nothing on that page other than a box to sign up for spam?
08:20 PM roycroft: https://docs.millmagesoftware.com/latest/#
08:20 PM roycroft: i have been trying to be nice and help you
08:20 PM roycroft: i am officially done with that
08:21 PM Tom_L: i'm not trying to be nice :)
08:21 PM roycroft: it is clear now that you live to be contrary, and i do not need any more of that in my life
08:21 PM roycroft: so you're on your own now
08:21 PM roycroft: and we get that you don't like freecad
08:21 PM roycroft: further whining about it is not welcome
08:21 PM roycroft: thank you very much
08:21 PM Tom_L: roy, before you invest time in freecad i'd think it time better spent with sw and it's cam
08:21 PM fluffywolf: the first link you gave, shows nothing but a box asking for your email. no way to close it, clicking outside the box does nothing, etc.
08:22 PM roycroft: that's my intent, tom_l
08:22 PM roycroft: and as soon as the mini router is working i shall do that
08:22 PM roycroft: speaking of which, i have very little work to do on the cabinet before it's time to install the electronics, but i spent 7 hours in town today, and did not get that work done
08:22 PM roycroft: perhaps after dinner, or else first thing in the morning
08:23 PM Tom_L: i had a question about your cabinet
08:23 PM roycroft: what is that?
08:23 PM Tom_L: what about emf and electrical noise in a wood box?
08:23 PM roycroft: i do not anticipate significant problems with that
08:23 PM Tom_L: i hope you're right
08:23 PM roycroft: however, i'll be using shielded cables where appropriate inside the cabinet
08:23 PM Tom_L: i was thinking about that today
08:24 PM roycroft: and worst case, i can build a faraday cage inside the cabinet
08:24 PM fluffywolf: roycroft: https://imgur.com/a/27bl9P9 this is what it shows for me. If you consider my asking if it contains any actual content to be "liv[ing] to be contrary", you must be seeing something else. lol
08:24 PM * roycroft has thought about these things
08:24 PM roycroft: i gave you two links, fluffywolf
08:25 PM fluffywolf: I found my stepper drivers to be very EMF-y, and do highly suggest shielding both the motor power cables and the step/dir cables.
08:25 PM Tom_L: i did
08:25 PM Tom_L: and gnd the stepper frames
08:25 PM * roycroft already said he'll be using shielded cables inside the cabinet
08:25 PM Tom_L: yeah
08:26 PM acer is now known as _unreal_
08:26 PM roycroft: and, of course, i have shielded cables to go from the cabinet to the motors, to replace the flat cables that are there now (and that work)
08:26 PM Tom_L: knowing you i'm sure you thought about it, it just came to me and i wondered
08:26 PM fluffywolf: looks like it only has windows/macos versions... does it WINE?
08:26 PM roycroft: since i don't always know what i'm doing, i consider most of these projects as at least somewhat iterative
08:27 PM Tom_L: i had noise issues on my old sherline until i rewired it
08:27 PM roycroft: starting as simply as makes sense to me
08:27 PM roycroft: and always being prepared for intersting detours
08:29 PM roycroft: thank goodness for din rails and modular components
08:29 PM Tom_L: wonder what ever happened to loet... maybe his haphazard work ethic finally bit him
08:30 PM fluffywolf: my sherline is still using the flashcut box it came with, with a windows laptop... haven't powered it up in a while. also got a mesa board to get rid of the flashcut box, but projects, time, etc.
08:30 PM Tom_L: my flashcut box was serial
08:30 PM fluffywolf: mine too
08:30 PM Tom_L: it's in a box now
08:30 PM roycroft: that's what i was thinking, tom_l, but i hope i'm wrong
08:30 PM fluffywolf: and tied to an utterly ancient windows program that, among other things, crashes if a screensaver comes on. heh.
08:30 PM roycroft: i know a lot of germans
08:30 PM Tom_L: seemed to always have a fresh wound to show
08:31 PM roycroft: and while ichguckslive and loetmichel seem like two peas in a pod, they are unlike most germans i know
08:31 PM fluffywolf: I got a mesa ethernet board to interface to the stepper box instead of the flashcut box, but setting it up is another project.
08:31 PM Tom_L: the stepper box wouldn't work for me. too slow
08:32 PM roycroft: i should finish my leather projects to night, and get bac to the controller tomorrow
08:32 PM JT-Mobile: long day
08:32 PM roycroft: i just got a big chisel and slick for timber framing
08:33 PM roycroft: they are both way too big to fit in my chisel drawer - they need to be wall mounted
08:33 PM fluffywolf: reading comments, sounds like millmage dropped linux support for the RC version, and will not be adding linux support in the near future.
08:33 PM roycroft: and i need leather edge protectors
08:33 PM Tom_L: JT-Mobile, you should be worn out or you didn't play hard enough :)
08:33 PM xxcoder: wonder why
08:33 PM JT-Mobile: I'm worn out totally and fd&h
08:34 PM roycroft: that's one of the town errands today - i had to get some longer leather rivets than i had, as the chisel and slick are too thick
08:35 PM roycroft: stitching through 12mm thick leather is not going to be fun
08:36 PM fluffywolf: only tool I have for timber framing is one of those circular saws with a chainsaw sticking out the bottom... and I'm not sure I still have it, since I lent it to someone a couple years ago... lol
08:36 PM xxcoder: intresting read on why they dropped it. makes sense I guess
08:36 PM roycroft: i have a 15" circular saw for cutting beams
08:36 PM xxcoder: seems lightburn is same, dropped linux support
08:36 PM roycroft: i wish i had a chain mortiser, but i don't
08:36 PM rdtsc: conductive silver paint inside
08:37 PM roycroft: and can't cost justify getting one, at least not right now
08:37 PM roycroft: rdtsc: or line the enclosure with think copper sheet
08:37 PM fluffywolf: I actually do have a makita beam saw, but no blade for it... takes a 15-3/8" or some other odd size.
08:37 PM roycroft: or copper window screen
08:37 PM rdtsc: https://www.amazon.com/conductive-spray-paint/s?k=conductive+spray+paint
08:37 PM fluffywolf: 16-5/16 according to google.
08:37 PM roycroft: i'm hoping i don't have to do any of that
08:38 PM roycroft: i just spent a lot of time sanding and dyeing and shellacking and waxing the inside of the cabinet
08:38 PM roycroft: i'd prefer not to cover that up
08:38 PM roycroft: but if i have emf problems i'll do what needs to be done
08:38 PM fluffywolf: you could always build small boxes for the parts causing problems, so as not to cover up shiny woodworking.
08:39 PM roycroft: or use shielded cables inside the cabinet and probably not have to worry about it :)
08:39 PM JT-Mobile: https://youtu.be/90WgZfvb2-Q
08:39 PM fluffywolf: shellac is semi-banned here, annoyingly.
08:39 PM fluffywolf: water-based poly is the only thing you can get.
08:39 PM roycroft: why would it be banned?
08:39 PM fluffywolf: no shellac or oil poly
08:39 PM roycroft: because of the ethanol?
08:39 PM fluffywolf: the alcohol content doesn't meet VOC limits.
08:40 PM fluffywolf: can't buy denatured alcohol either.
08:40 PM * roycroft guesses fluffywolf lives in the carb state
08:40 PM fluffywolf: yep!
08:40 PM fluffywolf: lol
08:40 PM roycroft: i thought about moving to arcata
08:40 PM roycroft: but then i thought about carb
08:40 PM fluffywolf: I'm a few miles from arcata.
08:41 PM roycroft: i love camping down there and visiting down there
08:41 PM roycroft: actually, arcata itself would probably not make me happy
08:41 PM fluffywolf: bring a gallon of denatured next time you do. :)
08:41 PM roycroft: it's pretty cool and foggy
08:41 PM fluffywolf: I've heard you can still get it from the local marine supply place labeled as stove fuel, but I haven't tried.
08:41 PM roycroft: i have a good friend who lives in blue lake
08:42 PM roycroft: that's just far enough inland that it's a lot warmer and sunnier
08:42 PM fluffywolf: yes, blue lake is *much* sunnier.
08:42 PM fluffywolf: I'm in the hills between arcata and eureka, and get the constant bay fog here.
08:43 PM roycroft: bayside?
08:43 PM roycroft: indianola?
08:43 PM roycroft: i know those places because they're on the old highway
08:44 PM roycroft: and i tend to drive on old highways when they are there
08:44 PM fluffywolf: indianola area
08:44 PM roycroft: so yeah, pretty close to eureka
08:44 PM roycroft: and the hills to the east probably stop the fog and keep you blanketed with it
08:45 PM * roycroft will be staying in oregon
08:45 PM fluffywolf: not only do I get the constant bay fog, but the little valley I'm up in traps cold air, making my place colder than the rest of the coast, so winter kills geraniums, succulents, and all sorts of other plants that grow just fine everywhere else on the coast...
08:46 PM * roycroft heads off to do some work and make dinner after
08:47 PM fluffywolf: I wouldn't mind living in, say, portland... wouldn't fit in in the eastern parts of the state...
08:47 PM fluffywolf: cyas
08:52 PM fluffywolf: freecad downloading at 94K/sec... not terrible...
08:57 PM xxcoder: wolf maybe check out some of freecad files
08:57 PM xxcoder: see what other people did
09:14 PM xxcoder: yay. fixed minor power issue. I can now turn on my ac
09:30 PM _unreal_: OMG... I'm so wiped out. but I need to move stuff into the attic. but I dont want to. its 10pm and I'm soooo tired
09:30 PM _unreal_: hate moving
09:37 PM _unreal_: one of the things I have to do for sure is fix the insulation. the DUMB DUMBs installed it upside down and a lot of it is messed up or just removed in the attic :/
09:37 PM _unreal_: I'll prob just get new insulation and lay it correct. its amazing they put the paper side down and ripped a lot of the paper
09:37 PM _unreal_: just amazing
09:38 PM lfluffywof: is that automatically incorrect? the vapor barrier usually goes towards the living space, no?
09:39 PM _unreal_: no
09:40 PM _unreal_: the paper side is suposed to be out and visible. so you can take a stable gun and take down the paper to the 2x4 beams. Its known as the draft seal
09:41 PM _unreal_: the vapor barrer as your stating is what is installed on the outside of the house first under the shingles both siding and roofing.
09:42 PM _unreal_: paper is NOT a vaper barrior. paper is used to let moisture buy so its not trapped in the insulation. But paper DOES do a good job at cutting down on drafts.
09:45 PM lfluffywof: the first non-reddit google result is https://todayshomeowner.com/insulation/guides/which-way-to-face-insulation/ , which says "Attics: Facing should point down toward the ceiling below."
09:46 PM lfluffywof is now known as fluffywolf
09:46 PM fluffywolf: paper down seems to be consensus on reddit as well
09:46 PM _unreal_: I come from maine
09:47 PM _unreal_: the insulation should always face the "heated/cooled" side. the paper should be to the other side
09:49 PM _unreal_: if you dont you will have mold and mildew
09:49 PM fluffywolf: https://www.antheminsulation.com/which-way-does-insulation-face-in-an-attic/ also says the paper should go down
09:50 PM fluffywolf: it says the paper needs to go down to prevent mold and mildew. lol
09:51 PM fluffywolf: I'm not an insulation expert, but I've always heard what these pages say, the paper always goes towards the living space.
09:56 PM fluffywolf: https://www.mainehousing.org/docs/default-source/ehs-partners-library/maine-weatherization-programs/technical-tools/field-standards-and-guides/maine-weatherization-standards-02242020.pdf?sfvrsn=1d298915_9 "If batt insulation is used, the vapor retarder should always face the conditioned building space." per maine housing authority.
09:57 PM _unreal_: https://valleyinsulationllc.com/attic-insulation-faced-or-unfaced/
09:57 PM _unreal_: says exactly waht I'm dealing with
09:58 PM _unreal_: You can use faced or unfaced batting when installing between the roof rafters of finished attic spaces. When using paper or plastic batting insulation, that moisture barrier should face outward toward the attic space.
10:00 PM -!- #linuxcnc mode set to +v by ChanServ
10:04 PM fluffywolf: seems there's disagreement, then. lol
10:05 PM fluffywolf: since offical-ish sources (like maine housing authority) say paper down, can't really call them DUMB DUMBs for doing it that way...
10:05 PM fluffywolf: also means you probably shouldn't spend any effort fixing it...
10:09 PM fluffywolf: this place (manufactured home) has plastic side down.
10:35 PM fluffywolf: freecad finished downloading... started making my part... was going pretty well until I tried using the trim tool on my sketch... Program received signal SIGSEGV, Segmentation fault.
10:35 PM fluffywolf: and once again, I manage to crash freecad within minutes of opening it.
10:35 PM xxcoder: that is just strange
10:36 PM fluffywolf: I think I trimed a line being used as a constraint, and rather than responding sanely, it did what freecad always does.
10:36 PM fluffywolf: createNewConstraintsForTrim looks like the most relevant bit of the big trace.
10:38 PM fluffywolf: I've been trying freecad for two decades, and every time I manage to segfault it within minutes. lol
10:49 PM _unreal_: hence I use spaceclaim
10:49 PM _unreal_: and fusion360
11:30 PM roycroft: i haven't been following abom's channel for a while - for quite a long time, actually - but i'm watching it tonight, and he's moving his cnc machines around, and said he's selling the cnc lathe
11:30 PM roycroft: the big mill is gone already
11:31 PM fluffywolf: he's very talented, but I find his videos... overly long.
11:33 PM roycroft: it's good background video sometimes
11:33 PM xxcoder: wow wonder why hes selling cnc stuff off. maybe just not his style
11:34 PM roycroft: the channel was better when he was machining huge parts
11:34 PM roycroft: manually
11:34 PM roycroft: all this building out a new shop and trying to figure out cnc hasn't been as good
11:35 PM xxcoder: cnc is great for bulk orders, or extremely complex cant be manually made ones
11:35 PM xxcoder: he dont seem to have such so dunno
11:36 PM roycroft: he's done some neat things with the cnc machines
11:36 PM fluffywolf: I haven't seen any of his cnc content. I thought he was entirely manual. lol
11:36 PM roycroft: he leased a new shop about 3 years or so ago
11:37 PM roycroft: he still has the main shop at his house
11:37 PM xxcoder: I had dropped him on his over year long length of "oh look new thing"
11:37 PM roycroft: but he got a bunch of big cnc machines for the new shop
11:37 PM roycroft: yeah, that was when he was moving into the new shop
11:37 PM roycroft: he had a cnc mill that was about 6m long that is gone
11:38 PM fluffywolf: that's a big mill.
11:38 PM roycroft: yes
11:38 PM roycroft: he had put a dozen or so kurt vises on it
11:38 PM roycroft: and was making lots of multiple parts
11:39 PM roycroft: for production that's great
11:39 PM fluffywolf: you have to make a lot of parts to pay for a mill that size.
11:39 PM roycroft: but he's always been more of a job shop kind of guy
11:39 PM roycroft: unless you're abom
11:39 PM roycroft: you get sponsored
11:39 PM roycroft: keep in mind that abom is the first person in the universe to ever make a profit with a shaper
11:40 PM fluffywolf: heh. I was watching a couple matt's off-road recovery videos, which I haven't done for a while, since they got way too commercial... and half the videos are "and look at this cool <thing> we got sent!"...
11:40 PM fluffywolf: lol
11:40 PM roycroft: the cnc gear was definitely sponsored
11:41 PM roycroft: he talked that stuff up in many videos, and did videos of the company coming out to install/set them up
11:41 PM fluffywolf: I saw the world's cutest shaper at a swap meet once, and ever since I've regretted not buying it.
11:41 PM fluffywolf: it was a little tabletop one
11:41 PM roycroft: quinn from blondihacks is the second person ever to make money with a shaper
11:41 PM roycroft: hers is a little one
11:41 PM fluffywolf: hers is way too shiny.
11:41 PM roycroft: and she isn't even making parts with it yet
11:41 PM roycroft: but she's generating clicks with it
11:41 PM fluffywolf: no tool should look like that if it's more than a month old. :P
11:42 PM roycroft: most of my machines look pretty new, and some of them are decades old
11:42 PM fluffywolf: heh. being poor, all my machines are always rusty and paint-optional...
11:43 PM roycroft: when i first started buying festool i poo-pooed the systainers
11:43 PM roycroft: they seemed an unnecessary added expense, and took up a lot of room
11:44 PM roycroft: but having a significant investment in festool gear now, all of it well-used, i can say that the two sanders that i use pretty much daily and never go back in their systainers look well-used, but all the other tools still look like new
11:45 PM roycroft: systainers do help a lot in protecting the tools
11:47 PM roycroft: as importantly, since the festool stuff is all systems, not just bare tools, everything has lots of accessories
11:47 PM roycroft: keeping them in their systainers, i've never lot so much as even a screw or nut
11:48 PM roycroft: and i can always find whatever i need to set up a tool instantly - there is never any looking around for a fence or an extraction hood or whatever
11:48 PM roycroft: it's all always in the systainer along with the tool
11:52 PM roycroft: aah, abom is getting a new big mill
