03:51 AM lcnc-relay: <travis_farmer@discord> Morning
03:53 AM lcnc-relay: <meisterdippel@discord> moin
04:24 AM Tom_L: morning
04:52 AM NetPipe: happy gcode morning to you
04:56 AM JT-Cave: morning
05:00 AM lcnc-relay: <turboss@discord> good morning
05:30 AM memleak: turboss! hey!
05:30 AM lcnc-relay: <TurBoss> hello memleak
05:31 AM memleak: you're really good at python :)
05:32 AM lcnc-relay: <TurBoss> hehe thanks I was bad at the begining 🙂
05:34 AM memleak: would you have any idea how to debug this?
05:34 AM memleak: https://sourceforge.net/p/emc/mailman/message/58847690/
05:35 AM lcnc-relay: <TurBoss> bash?
05:36 AM lcnc-relay: <TurBoss> and rip install?
05:36 AM memleak: system install
05:37 AM memleak: I'm updating the linuxcnc gentoo package
05:40 AM memleak: i found a lot of threads on the forum with the "cannot find module linuxcnc" error but nobody really shares they changes and fixes they made in order to get past it
05:40 AM lcnc-relay: <TurBoss> check if linuxcnc installed somewhere is in path python3 -c "import sys;print(sys.path)"
05:40 AM memleak: so I run `python` then run `import sys;print(sys.path)` ?
05:41 AM lcnc-relay: <TurBoss> yes or all in oneliner
05:41 AM memleak: ah ok
05:41 AM lcnc-relay: <TurBoss> that will print
05:41 AM lcnc-relay: <TurBoss> maybe python 3.11 vs 3.12 paths
05:43 AM memleak: i only have one version of python installed but i'll try it, thanks!
05:43 AM memleak: brb gotta reboot into linux
05:43 AM lcnc-relay: <TurBoss> 👍️
05:52 AM memleak: ok this is what i got: ['', '/usr/lib/python312.zip', '/usr/lib/python3.12', '/usr/lib/python3.12/lib-dynload', '/usr/lib/python3.12/site-packages']
05:53 AM lcnc-relay: <TurBoss> is linuxcnc in /usr/lib/python3.12/site-packages
05:53 AM lcnc-relay: <TurBoss> not sure
05:54 AM memleak: https://pastebin.com/88vyBihk
05:55 AM lcnc-relay: <TurBoss> can you try "export PYTHONPATH=/usr/lib/python3/dist-packages/:$PYTHONPATH" ?
05:58 AM memleak: ok latency-test works now!
05:58 AM lcnc-relay: <TurBoss> hurray!
05:58 AM memleak: i think the sim axis interface is broken again in linuxcnc though
05:58 AM lcnc-relay: <TurBoss> then linuxcnc should be installed in site-packages
05:59 AM memleak: https://pastebin.com/Y4YscVKv
05:59 AM lcnc-relay: <TurBoss> yeah hal moduels not in PATH
05:59 AM memleak: count= and names= are mutually exclusive and2: rtapi_app_main: Invalid argument (-22
06:01 AM memleak: i don't know how to change the installation path of those..
06:01 AM memleak: there's no ./configure option for it
06:01 AM lcnc-relay: <TurBoss> 😕
06:01 AM lcnc-relay: <TurBoss> I dont know..
06:01 AM memleak: AH! I can write an environmental variable to /etc/env.d
06:02 AM lcnc-relay: <TurBoss> 😲 great
06:02 AM memleak: I already have one for TCLLIBPATH. /etc/env,d/99linuxcnc: TCLLIBPATH="/usr/lib/tcltk/linuxcnc"
06:03 AM memleak: so now i just add that line in there and it's done
06:03 AM memleak: but now the count= and name= issue, i think that's actually an upstream bug with the sim axis
06:03 AM memleak: the sim axis breaks a lot i've noticed...
06:11 AM memleak: turboss, thank you!
06:11 AM lcnc-relay: <TurBoss> works?¿!
06:11 AM lcnc-relay: <TurBoss> hurray!
06:12 AM memleak: yup!
06:19 AM memleak: ok I'm switching the built-in browser from epiphnay/gnome web to konqueror because not even yahoo loads
06:23 AM memleak: konqueror uses nodejs and qtwebengine :)
06:27 AM memleak: maybe not the nodejs part actually but it is a dependency at least
06:27 AM memleak: plus gnome web keeps crashing
06:43 AM Tom_L: turboss, maybe you could look at the bridge bot?
06:44 AM Tom_L: getting double posts & alot of the links are 404 on this side
06:44 AM lcnc-relay: <TurBoss> i took a look but looks like when someone pastes a link to a image discord deletes it and replaces that with a preview so get double post
06:44 AM lcnc-relay: <TurBoss> ☹️
06:44 AM lcnc-relay: <TurBoss> can't figure...
06:44 AM lcnc-relay: <TurBoss> I can take a look at the 404
06:48 AM Tom_L: 32°F hi 38°F
06:52 AM memleak: brb again
07:08 AM JT-Cave: https://pasteboard.co/Qjlnb3DpGSfD.png
08:22 AM JT-Cave: https://youtu.be/lpXapGZaF6I
08:52 AM rdtsc-wk: Nice JT! May have noticed a quirk with estop button color and text; it follows logical operation (off initially, changes text and color when pressed), but only once. Physical estop switch or clicking estop button does stop, but button never changes color/text after that. Same with power button - works correctly once. Do have a MPG and estop latch in .hal file - unsure if that has anything to do with it; will check tonight.
09:22 AM JT-Cave: so long as you are using the push button to change power and estop the colors should change
09:23 AM JT-Cave: I would need to move that to status.py to change colors with remotes
09:27 AM rdtsc-wk: maybe that's it - manual actuations work fine (as long as estop doesn't remotely turn off power), but the moment power is on, estop tromples over the power button state, and likewise with the estop switch - will have to look into it tonight
09:30 AM memleak: LinuxCNC I believe is now one step away from working on Gentoo again :)
09:31 AM memleak: I ran into the count= names= issue before, I think andy had to push a change to get it going again
09:31 AM memleak: https://github.com/LinuxCNC/linuxcnc/issues/3205
09:33 AM memleak: Can someone test the sim axis on their end to see if it's working?
09:33 AM memleak: I'm using the latest 2.9 checkout
09:35 AM jpa-: i kinda hope that at some point we'll get a new and better setup syntax for hal
09:35 AM memleak: is that what's broken for me right now?
09:36 AM memleak: it's passing two params when it should be passing one?
09:36 AM jpa-: probably one file uses count= and another file uses names= or something
09:36 AM memleak: ah :)
09:36 AM jpa-: there are a bunch of fun workarounds and hacks to make the hal syntax a bit more bearable, and they interact in funny ways
09:37 AM memleak: i'm going to try and find it and rip one of them out
09:39 AM memleak: oh no, there's a lot :(
09:41 AM memleak: ^a lot of files
09:41 AM JT-Cave: if you need more than one you have to use either count or names
09:42 AM memleak: cooling.hal:loadrt and2 count=3
09:42 AM memleak: and2 is what showed up in the log
09:47 AM memleak: ok the sim lathe works!
10:15 AM memleak: linuxcnc ebuilds are fixed: https://github.com/NTULINUX/ntu_overlay/commit/97bf40771989cd80c067a291a7a17557797a1b68
10:15 AM memleak: oh yeah, just letting you know, linuxcnc works with LTO :)
10:18 AM lcnc-relay: <skunkworks8841@discord> LTO?
10:41 AM rdtsc-wk: Looks like LTO stands for Link-Time Optimization, a compiling feature: https://wiki.gentoo.org/wiki/LTO
10:53 AM memleak: yes :) exactly that
10:55 AM memleak: I'm forking the 6.12 PREEMPT_RT kernel right now to update it from 6.12-rc4 to 6.12.1 and allow for -O3 enablement through Kconfig :)
10:57 AM memleak: -O3 is a compiler flag that can optimize for more performance (built linuxcnc with it too) at the cost of increased memory usage and slower compiling time
11:01 AM memleak: I got 32GB of RAM though so I'm fine :D
11:02 AM memleak: If anything I need more video memory. 4GB is not enough these days :(
11:08 AM bjorkintosh: get ALL The RAM
11:08 AM bjorkintosh: there's no such thing as 'too much ram'
11:08 AM bjorkintosh: (unless it's an embedded device, of course)
11:12 AM memleak: the 7900 XTX has 24GB of VRAM :)
11:22 AM * roycroft does not understand the need for a lot of vram for a cnc controller
11:23 AM bjorkintosh: roycroft: 'there is no such thing as too much ram'
11:23 AM bjorkintosh: get ALL the RAM!
11:25 AM memleak: i dual boot and game on windows a lot
11:25 AM roycroft: so i bought an espresso machine about 15 or so years ago
11:26 AM roycroft: it's small - single group - but it is fairly capable and has a commercial group head
11:26 AM memleak: i have an aeropress!
11:26 AM roycroft: it came with a crappy consumer-type steam wand, though, that has never worked well
11:26 AM roycroft: about 10 or 12 years ago i bought a steam wand upgrade, and promptly lost it
11:27 AM roycroft: and did not want to invest in another
11:27 AM roycroft: over the holiday weekend i was unpacking some moving boxes, and i found it and installed it
11:27 AM roycroft: now i'm getting nice, velvety steamed milk, and the quality of my cappuccinos has gone up dramatically
11:27 AM roycroft: not that they were bad before
11:28 AM * roycroft has never used an aeropress, but word is that they're really good
11:29 AM roycroft: the question is: do you weigh your coffee grounds before putting them in the aeropress?
11:30 AM roycroft: if i cannot make espresso, a french press is my next choice in brewing methods
11:30 AM roycroft: and an aeropress is essentially a french press on steroids
11:32 AM -!- #linuxcnc mode set to +v by ChanServ
11:41 AM bjorkintosh: ah so how did you lose the steam wand in the first place?
11:42 AM memleak: The aeropress comes with a scooper, I use roughly one scoop to make anywhere from 16 to 20oz depending on my desired strength
11:42 AM roycroft: i have no idea
11:42 AM roycroft: i probably put it in a drawer
11:42 AM roycroft: and it got buried
11:43 AM roycroft: when i moved i would pull out a drawer and dump its contents into a box
11:43 AM * roycroft appreciates that memleak enjoys good coffee but is not an obsessive snob about it
11:44 AM roycroft: i have never weighed my coffee when making espresso drinks, and i have friends who chastise me about that all the time
11:44 AM roycroft: i also did not install a pid controller on the espresso machine, so the temperature may vary slightly from time to time
11:44 AM roycroft: again, something my snob friends give me a hard time about
11:45 AM roycroft: i consistently make very good cappuccinos that rival what i can get at a good coffee shop, and i do not have to leave my house to get it
11:46 AM roycroft: the nearest "good" coffee shop is now almost an hour's drive from here anyway
11:47 AM * roycroft also does not use bottled water for his espresso machine
11:47 AM roycroft: i did spend more money on the grinder than on the espresso machine, though, so i guess i did one thing right :)
11:53 AM xxcoder: lol yeah if its plenty good to you, I dont see reason for you to have to go to a shop, unless its for social event of some kind
11:54 AM roycroft: well before i bought my espresso machine i'd go to a coffee shop several times/week, because i really like cappuccinos
11:54 AM roycroft: i had a french press for the days when i did not have the time or inclination to go buy a coffee
11:54 AM roycroft: but most days i'd end up going to a coffee shop
11:55 AM roycroft: the machine and grinder (about a $1k investment at the time) paid for themselves in about 10 months just in the cost of the drinks alone, not to mention the time and fuel invested
11:56 AM roycroft: 50 cents vs $4 on a daily basis makes a big difference
11:56 AM xxcoder: yep
11:57 AM roycroft: my lab jack is out for delivery, so i can start mocking up the lower part of my laser enclosure
11:57 AM roycroft: the 1064nm laser head won't be here for a few days though
11:57 AM roycroft: i have not been able to find the dimensions of it, and i hope it's not much taller than my 20w diode head
11:58 AM * rdtsc-wk thinks Roycroft is competing against JT for "most stuff done in shortest time" :)
11:58 AM roycroft: i don't want to have to do a significant remodel on the upper part of the encloser to accomodate a taller laser
11:58 AM roycroft: i am pushing kind of hard right now
11:58 AM roycroft: i still have to finish moving, but i'm getting really close to being done
11:58 AM bjorkintosh: rdtsc-wk: *before* nap time.
11:59 AM roycroft: having two injuries this year, both of which stopped all progress for a prolonged period of time really put me behind schedule
11:59 AM roycroft: so now it's time to catch up
11:59 AM rdtsc-wk: just be careful not to have an accident... always happens to me when I rush
11:59 AM roycroft: operating the jointer and thicknesser this weekend was really huge for me - the first time i've been able to use those machines in almost a year
12:00 PM roycroft: and the dust collector, while still sub-optimal, is now working better than ever
12:00 PM * roycroft is pacing himself
12:01 PM roycroft: both injuries this year might have been avoidable, albeit at an expense
12:01 PM roycroft: i'm not looking for a third go at hurting myself
12:01 PM roycroft: i still have not built the hand rail for the back steps
12:02 PM roycroft: but i also do not use the back steps when they are wet or at night
12:02 PM memleak: yeah i spent a _lot_ on my grinder
12:02 PM roycroft: and don't even use them much during the day when it's dry
12:02 PM roycroft: the grind is almost everything
12:02 PM memleak: Baratza Encore is mine
12:02 PM roycroft: i got a rancilio rocky
12:02 PM memleak: conical burr
12:03 PM memleak: canonical burr with ubuntu
12:04 PM roycroft: i did a couple reversable mods to my grinder
12:04 PM memleak: you put ubuntu on it?
12:04 PM roycroft: no
12:04 PM memleak: XD
12:04 PM roycroft: it's worked flawlessly for about 15 years
12:04 PM roycroft: the grinder has two switches - a main power switch and a momentary action switch for engaging the motor
12:05 PM roycroft: as it comes it's a pain - you turn on the main switch, and then have to press and hold the motor switch while also holding the group head to receive the grinds
12:05 PM roycroft: i bypassed the momentary action switch
12:05 PM memleak: we need a linuxcnc powered coffee grinder.
12:05 PM roycroft: as well, the burr adjuster on the rocky is stepped
12:06 PM roycroft: and while the steps are pretty fine, sometimes one needs a grind in between the steps
12:06 PM roycroft: so i bypassed that and now it's continuously adjustable
12:06 PM roycroft: after those two mods it was an outstanding grinder
12:07 PM roycroft: there is a version of it with a doser, and some of the espresso carts that hang out in parking lots use that version
12:07 PM roycroft: it's really a pro grinder, not even pro-sumer
12:25 PM memleak: gotta go!
01:12 PM CloudEvil: A linuxcnc coffee grinder is clearly the wrong way. The right way is a arm to grab the bean, and then a micro shaper to slice the bean neatly into precise shapes.
01:25 PM rdtsc-wk: Use a Windows PC to shape a bean into Tux, heheheh
01:26 PM bjorkintosh: you mean, whack the bean with the pc, correct?
01:28 PM rdtsc-wk: If we stack enough Windows PCs on top of each other, it'll definitely work as a grinder
01:29 PM bjorkintosh: btw, is there something like this, but smaller and with steel? https://www.industrialtoolcrib.com/more-industrial-products/bessey-vas-23-2k-clamp-woodworking-strap-clamp-variable-23-ft-strap
01:32 PM roycroft: as far as smaller goes, i don't know
01:32 PM roycroft: but there are strapping machines that wrap steel straps around crates
01:33 PM roycroft: they use crimp connectors to hold the straps in tension, so the bands are essentially one-time use
01:33 PM -!- #linuxcnc mode set to +v by ChanServ
01:35 PM roycroft: https://www.mcmaster.com/20275T23/
01:35 PM roycroft: that one can handle 3/8" straps
01:35 PM roycroft: i don't know if that's small enough for you
01:37 PM roycroft: https://www.mcmaster.com/5967N21/
01:37 PM roycroft: that one goes down to 1/4"
01:37 PM bjorkintosh: hmm. I find there are not many clamping options when it comes to squeezing.
01:37 PM rdtsc-wk: https://www.amazon.com/VEVOR-24-inch-Wrench-Diameter-Capacity/dp/B07MKSSH5S ?
01:37 PM bjorkintosh: worm geared hose clamps are what I use right now. but they're ... problematic.
01:38 PM rdtsc-wk: ...because Vevor makes one of those too, heh
01:38 PM roycroft: vevor makes everything
01:38 PM bjorkintosh: they heat up really fast when the going gets tight enough.
01:39 PM roycroft: and vevor did not exist a few years ago
01:39 PM roycroft: they went from nothing to "if you can imagine it we make it" almost overnight
01:39 PM rdtsc-wk: they probably make an espresso also
01:40 PM rdtsc-wk: https://www.amazon.com/VEVOR-Espresso-Machine-Semi-Automatic-Professional/dp/B0D3TT9WCK yup lol
01:41 PM roycroft: of course they do
01:42 PM xxcoder: vevor rockets when
01:42 PM rdtsc-wk: now are the espresso machines right next to the oily chain wrenches in their warehouse...
01:46 PM roycroft: now that the united states is officially transitioning from an unofficial oligarchy to declared oligarchy, with elon musk being the first official oligarch, there will be no other rockets made other than the spacex ones
01:47 PM roycroft: if vevor make one there will be a 10000% tariff imposed on it
01:48 PM Tom_L: bezos is making em too
01:49 PM Tom_L: the kid makes parts for both of them
01:50 PM roycroft: bezos will be shut down
01:50 PM xxcoder: today and tomorrow will have barely freezing nights. fun!
01:50 PM roycroft: we had a light frost this morning
01:50 PM Tom_L: i see biden pardoned his kid after he said he wouldn't
01:50 PM roycroft: -2 when i woke up
01:50 PM roycroft: yeah, he did
01:51 PM roycroft: and i'm pretty pissed off about that
01:51 PM Tom_L: they all lie to us
01:51 PM Tom_L: mis use of power
01:51 PM * roycroft reiterates that he is not aligned with either of the major parties
01:51 PM Tom_L: not to get started on that topic...
01:52 PM * bjorkintosh simply wants to know where a major party is and why he wasn't invited.
01:53 PM roycroft: i think the best thing biden could do between now and the end of his term is to issue blanket pardons to everyone on the president-elect's enemies list, and to the president-elect as well
01:53 PM roycroft: i thought ford's pardon of nixon was a mistake, but circumstances are different now
01:54 PM lcnc-relay: <skunkworks8841@discord> would that be an olive branch?
01:55 PM roycroft: i think it's just practical
01:55 PM roycroft: nixon did not have a maga movement
01:55 PM roycroft: his own party were against him in the end
01:55 PM roycroft: the pardon did nothing to 'heal' the nation
01:56 PM rdtsc-wk: 248 years... and still a pissing-contest.
01:56 PM roycroft: but a pardon of the former president might calm down his 38 million followers
01:56 PM roycroft: the biggest mistake the founding fathers made was naively believing that we could function without political parties
01:57 PM xxcoder: interesting thing is that accepting pardon means admitting crime was done, which is why I wonder if incoming president would even accept it
01:57 PM roycroft: they were too optimistic for their own good
01:57 PM roycroft: he might not
01:58 PM xxcoder: reminds me of that time pardoned guy was telling people he didnt do the crime, so judge took him back into jail
01:58 PM roycroft: and folks like jack smith and nancy pelosi might not either
01:58 PM roycroft: it's not really an admission of guilt, but it implies guilt
01:58 PM xxcoder: true
01:58 PM roycroft: hillary clinton needs a pardon too
01:59 PM roycroft: the "lock her up" chants will begin after the inauguration
01:59 PM roycroft: and it might just happen
01:59 PM roycroft: anyway
01:59 PM roycroft: i think i asked you this, xxcoder, but i think you were afk or i was when you answered
01:59 PM roycroft: do you have any information at all about that spindle controller that came with the cnc machine?
02:00 PM roycroft: it just says "mach3" on the pcb, and a bunch of chinese writing
02:00 PM roycroft: the bob says the same thing, but i'm already planning on tossing that and using a 7i96
02:01 PM roycroft: if i could just hook up a power supply to the spindle controller and a pot to adjust the speed, that would be a great start
02:09 PM xxcoder: roycroft: its pretty simple really. it accept signal from 0v to 10v
02:09 PM xxcoder: 0v is off, 10v is max speed
02:11 PM xxcoder: so board has 2 inputs and one out, power source for spindle, and 0-10v signal for inputs, spindle output to spindle itself
02:11 PM roycroft: ok, that is simple enough
02:11 PM roycroft: i can use that controller for now
02:11 PM roycroft: thanks
02:12 PM xxcoder: yeah. the spindle "fan" on top has 2 magnets epoxied inside it, to be used with 1khz sensor included in your misc box
02:12 PM xxcoder: no problem
02:12 PM roycroft: right, i found the sensor
02:12 PM roycroft: and a bracket to hold it
02:13 PM xxcoder: bracket is for different sensor type, I found out it wasnt fast enough to measure rpm beyond low speeds lol
02:13 PM roycroft: it's going to be a little while, probably, before i get that machine working
02:13 PM Tom_L: spinx-1 is the mesa interface for that
02:13 PM xxcoder: good sensor is square face umm teal color I think?
02:13 PM roycroft: but maybe sooner than i thought - depending on what i need to fabricate for the laser
02:14 PM roycroft: since my manual mill/drill is in storage, my only fabrication tools at the moment are drills and files
02:14 PM xxcoder: sensor isnt needed for spindle operation so you could just run spindle without feedback
02:15 PM roycroft: right
02:15 PM roycroft: but it's useful, especially with the tiny cutters i'll need to use with that spindle
02:15 PM roycroft: feed rate is going to be critical
02:16 PM Tom_L: chip load
02:16 PM xxcoder: thats cool :) well theres 2 magnets so feedback would be twice rpm so its easy enough to hal divide by 2
02:16 PM Tom_L: maintain that and you will have no problems
02:16 PM roycroft: i'll probably end up running it at full speed at all times, since it maxes out at 12,000rpm
02:16 PM * roycroft does not understand why tiny spindles are so slow
02:17 PM xxcoder: dont know also. my orginal plan was to use PID so linuxcnc could rise voltage if spindle is stalling at lower speeds
02:17 PM roycroft: yeah, i'll want to do that eventually
02:17 PM roycroft: but i can deal with manual speed control at first
02:18 PM xxcoder: indeed. theres very manual way also, it comes with knob (assuming I didnt lose it) you could use in place of 0-10v from board if you had to
02:18 PM roycroft: i'm going to focus on the laser first
02:18 PM roycroft: for indoor projects
02:18 PM roycroft: i also still need to get my utility sink installed
02:18 PM roycroft: which is going to require a fair amount of plumbing work
02:19 PM roycroft: not having that sink prevents me from doing a lot of things, and makes other things a lot more work than they need to be
02:19 PM xxcoder: ugh thanks for reminding me lol. have to empty tank today or tomorrow.
02:19 PM roycroft: plus, the sink is taking up a bunch of space in my portable garage
02:19 PM roycroft: space i could use for other things
02:19 PM roycroft: my belt grinder, for example, uses about the same amount of real estate as the sink, and i would really like to get my belt grinder moved here soon
02:20 PM roycroft: so the laser enclosure and the sink are my top indoor priorities, and the cnc router after that
02:21 PM roycroft: and i still have to get back to insulating and sheathing the shop walls as soon as the shed door is installed
02:22 PM xxcoder: fun lol
02:22 PM roycroft: it will all be good
02:22 PM roycroft: but i'll be pretty busy for a while
03:09 PM lcnc-relay: <Lcvette> is anyone in here using carousel comp?
03:10 PM lcnc-relay: <Lcvette> if so do you know if it allows for acceleration tuning of the drive output?
03:15 PM xxcoder: whew my home feels very hot after being outside emptying tank out
03:16 PM xxcoder: glad I decided to push though and do it today, probably will have unpredicted rain tomorrow and rest of week is predicted to rain
03:24 PM xxcoder: oh im wrong, looks like few days of no rain, but whatever, its good for few weeks
03:25 PM roycroft: the rain returns here later on this week
03:27 PM xxcoder: well I took advange of that, though im too tired to also refill water. tomorrow maybe
03:28 PM xxcoder: im my life, turning water into gray/black water lol
03:28 PM xxcoder: *it's
03:49 PM roycroft: you're supposed to be turning it into gold
03:49 PM roycroft: that's the ultimate goal, isn't it?
03:50 PM bjorkintosh: I discovered the simplest way to turn lead into gold was to become a ... plumber.
03:50 PM xxcoder: well some gray water was orginally golden water
03:52 PM {HD}_ is now known as {HD}
03:54 PM roycroft: not just anyone can become a plumber
03:54 PM xxcoder: certainly not me, if its hard work for me to simply empty out a tank
03:54 PM roycroft: it requires a fairly hideous butt crack, which is a genetic trait that most do not sport
03:56 PM bjorkintosh: yeah. but you can always just get a t-shirt: https://www.cheapundies.com/products/brand-breeders-white-plumber-university-butt-crack-tee
03:57 PM bjorkintosh: so if you don't have one on display, the shirt will reveal one, guaranteed.
03:57 PM xxcoder: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQ6oO4-40Drmak2ZXpECuh5V7vxaqA7AU-OHA&s
04:10 PM * roycroft would not trust a plumber with a paste-on butt crack
04:12 PM xxcoder: theres shirt that makes fake crack
04:19 PM * JT-Shop runs his first program on the BP with Flex
04:31 PM * roycroft wonders if ups will show up today or not
04:31 PM roycroft: they refuse to step foot on my property, so anything they bring gets left out in the street
04:31 PM roycroft: but even then they don't bother dropping it off half the time
04:33 PM roycroft: the driver told me "i won't enter someone's property because some people have dogs and i don't want to get a dog bite"
04:33 PM roycroft: if my front gate is wide open, an untethered dog will not stop at the property line
04:33 PM roycroft: not that i have a dog, tethered or otherwise
04:34 PM roycroft: but that's the excuse for not delivering to my porch
04:34 PM roycroft: i have no idea why they sometimes just don't show up
04:34 PM lcnc-relay: <Lcvette> JT-Shop: make it rain chips!
04:35 PM xxcoder: it would be far more impressive if "chips" word was left out lol
04:35 PM * roycroft will be happy when he's running a machine with linuxcnc and any user interface, but will try flex as soon as he can after a machine is working
04:36 PM Tom_L: so i just ran the first set of threadmill tests
04:36 PM Tom_L: nothing broke.
04:36 PM JT-Shop: nice
04:36 PM Tom_L: i need to adjust things a bit
04:37 PM Tom_L: the OD numbers are off but i think i know why
04:37 PM Tom_L: RH LH ID OD all ran the proper paths
04:38 PM Tom_L: i do have a question though
04:38 PM Tom_L: on an internal thread you start at the bottom and mill upward. should i set the Z start plane at the bottom or the top end of the thread
04:39 PM Tom_L: ?
04:41 PM Tom_L: right now it's set for the bottom Z0 however that same plane is the start for external threads which start at the top
04:41 PM Tom_L: and mill downward
04:49 PM Tom_L: JT-Shop, how's flex working on the BP?
04:50 PM JT-Shop: working good just finding out what things I need to add to make it touch screen functional
04:50 PM JT-Shop: you find this out as you use the GUI
04:51 PM Tom_L: i know.. i changed mine around quite a bit
04:52 PM Tom_L: things you don't think about in sim
04:54 PM Tom_L: wow that fix was easier than i thought
04:54 PM Tom_L: i'd divided D/2 in 2 places and didn't realize it
04:56 PM JT-Shop: sometimes I do something like that in code and it can be fun to find sometimes but grep is my friend
04:56 PM xxcoder: grep is amazing
04:56 PM Tom_L: i had a hunch that's what it was
04:57 PM xxcoder: its probably almost as often used as cd
04:57 PM Tom_L: not sure i'll test on the mill again to day though
04:57 PM Tom_L: found a wood dowel about the right size to 'thread'
04:58 PM JT-Shop: I'm resting a bit before working on the C3
05:01 PM Tom_L: gonna be 22F in the morning
05:01 PM Tom_L: hi 42F
05:01 PM JT-Shop: 20°F here
05:02 PM xxcoder: "The answer to the great question...of Life, the Universe and Everything"f here
05:11 PM JT-Shop: https://youtu.be/lFiuCBTNGVU?t=1544
05:11 PM JT-Shop: interesting woodworking trick
05:11 PM JT-Shop: to find the center
05:13 PM xxcoder: hmm yeah
05:13 PM JT-Shop: sad ending
05:14 PM roycroft: aah, well ups just dumped my parcels off in the street
05:14 PM roycroft: and the lab jack happens to be made by vevor, btw
05:19 PM roycroft: and it's pretty nice - it does not have the razor-sharp edges that people complain about, so i won't have to do any deburring
05:20 PM xxcoder: lol it does seem like some stuff ordered is actually a "kit", requiring rebuild and finishing
05:21 PM xxcoder: capt certainly had experence of that
05:21 PM roycroft: almost anything from asia is like that
05:21 PM roycroft: our air stagnation warning has been extended through thursday
05:21 PM roycroft: yet people are still openly burning around here
05:21 PM xxcoder: geez.
05:22 PM roycroft: open burning is banned during the stagnation period, and even wood stove heat may be banned if things get too bad
05:22 PM xxcoder: im using as much electric heating as possible
05:22 PM roycroft: i have that heat pump, so it's all electric for me
05:22 PM xxcoder: proprane as backup here. I have set it to turn on at below 64f
05:22 PM bjorkintosh: i find that 'made in china' is no longer the crap it used to be.
05:22 PM bjorkintosh: it's approaching stuff made in korea, if not better.
05:23 PM xxcoder: it doesnt turn on most of day, only during night when its really cold
05:23 PM bjorkintosh: but what firmly remains trashy, are 'made in india' tools.
05:23 PM bjorkintosh: they always look like crappy cast iron pieces.
05:24 PM roycroft: taiwan was the new japan
05:25 PM roycroft: china is the new taiwan
05:25 PM roycroft: india is the new china
05:25 PM bjorkintosh: but it's been that way for as far as I know. 'always guaranteed crappy'.
05:25 PM bjorkintosh: I used to work in a shop where it was specifically stated 'no steel from india'.
05:26 PM bjorkintosh: don't get me wrong. I love indian food though.
05:26 PM roycroft: when india starts making decent stuff, i anticipate somewhere like nigeria or ethiopia will be the new india
05:27 PM bjorkintosh: I think Egypt will get there first.
05:27 PM bjorkintosh: or South Africa (if they ever get act together again)
05:27 PM bjorkintosh: *their.
05:27 PM roycroft: the problem is that the world is starting to run out of impoverished third-world countries to do crap manufacturing on the cheap
05:27 PM bjorkintosh: manufacturing and consumption. don't forget the last part.
05:28 PM roycroft: well we're doing all the consumption
05:29 PM JT-Woodshop: dicey part next... taking the spring out
05:29 PM xxcoder: theres literally over couple hundred countries, so probably not anytime soon
05:29 PM roycroft: anyway, this lab jack is pretty nice, and easy to disassemble, which is good, because i need to attach a platform to the top of it
05:29 PM bjorkintosh: how big is it?
05:30 PM roycroft: 200mmx200mm platform, 50mm high when fully lowered, and 300mm high when fully extended
05:30 PM roycroft: it's for the roller for my laser engraver
05:30 PM roycroft: i'm cutting a hole in the bottom of the main laser enclosure, and building a compartment below it for the roller axis
05:31 PM roycroft: when i need it i'll pull a lid on the base of the main enclosure, jack the roller up to the appropriate height, and when i'm done i'll lower it back down and put the lid back on
05:31 PM roycroft: the goal being to minimize setup time, as i don't anticipate a lot of margin on products i engrave
05:32 PM roycroft: every second i save is money in my pocket
05:32 PM roycroft: allegedly
06:14 PM * JT-Shop calls it a night
06:16 PM Tom_L: get the spring out?
06:34 PM lcnc-relay: <skunkworks8841@discord> 38% humidity..
06:35 PM roycroft: it's usually more like 98% here this time of year
06:35 PM roycroft: we're the opposite to most of the country
06:35 PM lcnc-relay: <skunkworks8841@discord> It is currently 10 degrees outside.. A few days ago it was 60%
06:35 PM lcnc-relay: <skunkworks8841@discord> who knew you need a dehumidifier in the winter
06:38 PM lcnc-relay: <skunkworks8841@discord> the windows on the next floor down didn't totally wet up last night.. Yay
06:40 PM xxcoder: my home is at 60%, my drying plants is sucking excess out of air
06:41 PM xxcoder: aloe, pemission, and english ivy
06:41 PM xxcoder: last one is super invastive but its in pot and I will never put it outside so its fine
06:41 PM xxcoder: room its in used to reach 90% pretty often
06:44 PM lcnc-relay: <skunkworks8841@discord> yikes..
06:44 PM rdtsc_away is now known as rdtsc
06:45 PM xxcoder: yeah.
06:45 PM lcnc-relay: <skunkworks8841@discord> This floor (attic) is now feels good. Might be all in my head.. But I think it used to have a smell - now no..
06:45 PM lcnc-relay: <skunkworks8841@discord> musty
06:45 PM xxcoder: those plants is amazing, though I probably would replace aloe and pemimmision plant with english ivy if I acciently kill those.
06:45 PM lcnc-relay: <skunkworks8841@discord> the floor below had mildew in all of the bedrooms.
06:46 PM lcnc-relay: <skunkworks8841@discord> If I can control that - yay!
06:46 PM xxcoder: I do suggest you buy in least one english ivy, it keeps humidity around 60
06:46 PM lcnc-relay: <skunkworks8841@discord> We should have some plants.. But I don't remember to water them
06:46 PM xxcoder: I dont either, so I use tkremind on my linux pc
06:47 PM lcnc-relay: <skunkworks8841@discord> 60 is too high here.
06:47 PM lcnc-relay: <skunkworks8841@discord> in the winter
06:47 PM xxcoder: only once a week for ivy thankfully so its easy. my living room dehumider isnt as good as plants, but I use its water to water plants. free water
06:47 PM lcnc-relay: <skunkworks8841@discord> the problem is the walls and windows sweat then.
06:47 PM lcnc-relay: <skunkworks8841@discord> *condensate
06:47 PM lcnc-relay: <skunkworks8841@discord> windows much worse.
06:48 PM xxcoder: yah I am still waiting for my winterizing sheets to arrive. https://www.amazon.com/gp/product/B0000CBJN3
06:48 PM lcnc-relay: <skunkworks8841@discord> the books up here have mildew in them from all the wetness.
06:48 PM xxcoder: well I do highly recommand ivy
06:49 PM xxcoder: buy one pot and see if room humidity in least get out of wet walls point
06:49 PM xxcoder: https://jayscotts.com/blog/plants-that-dehumidify/ btw thats what I read before deciding on those 3 plants
06:50 PM xxcoder: oh yes peperomia is that third plant
06:50 PM lcnc-relay: <skunkworks8841@discord> I would love to get a snip of the christmas cactus that my grandfather grew - I think all the kids have a plant based on the original
06:52 PM xxcoder: im tempted with spider plant too. looks cool, almost grass
06:55 PM xxcoder: peperomia probably will do just fine, its growing slowly but steady. im worried about aloe lol
06:55 PM xxcoder: if it dies ill just get spider grass I guess
06:56 PM Tom_L: helpful tip: remember to hit 'save' on the editor before you try and rerun the program
06:56 PM xxcoder: doh
07:02 PM bjorkintosh: what? you don't have a foot pedal for that?
07:04 PM bjorkintosh: something like this: https://www.amazon.com/PCsensor-Customized-Computer-Multimedia-Photoelectric/dp/B08SLX75K8?th=1
07:04 PM bjorkintosh: it becomes second nature to step on the thing after a few uses.
07:08 PM Tom_L: what are the other 2 for?
07:08 PM Tom_L: del & cut?
07:08 PM Tom_L: i'd get confused :)
07:08 PM bjorkintosh: hahaha
07:08 PM bjorkintosh: well. you can customize them as you please.
07:08 PM xxcoder: save, save for sure, save in case certainity failed
07:09 PM Tom_L: i did that on my ball mouse with catia
07:09 PM Tom_L: had buttons for pan tilt zoom etc so i didn't have to move my hand off it
07:11 PM bjorkintosh: I must say, it's a relatively cheap quality of life improvement.
07:11 PM bjorkintosh: the other thing I did was to get identical mouses for each hand.
07:14 PM Tom_L: pretty happy with the threadmill ops now
07:14 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/Threadmilling.mkv
07:15 PM Tom_L: i still need to test it on the mill
07:15 PM Tom_L: again
07:16 PM Tom_L: the first 'live' test was 'revealing'
07:17 PM Tom_L: bjorkintosh, you run the keyboard with your nose then? if both hands are tied up on mice
07:17 PM bjorkintosh: hahahaha.
07:18 PM Tom_L: vision commands
07:18 PM bjorkintosh: No. I only use one mouse at a time and I switch mouse hands without moving the mouse itself.
07:18 PM roycroft: i have two mouses for my cad workstation - a conventional one and a 3d one
07:19 PM Tom_L: i don't think i could run a mouse left handed
07:19 PM roycroft: i only use one at a time
07:19 PM * roycroft uses both with the same hand
07:19 PM roycroft: they are one above the other
07:19 PM bjorkintosh: I'm accustomed to switching hands.
07:19 PM roycroft: the 3d mouse does not move
07:19 PM * bjorkintosh just switched hands.
07:20 PM roycroft: i use the 3d mouse primarily for zooming and model rotation
07:20 PM bjorkintosh: a foot board could be configured to do that.
07:20 PM bjorkintosh: one for zoom in, the other for zoom out.
07:20 PM Tom_L: they had those fancy ball things at the votech and nobody used them
07:22 PM rdtsc: "space mice" are neat... full 3D control (any combination of x,y,z input.) As a consequence, any mis-application of force sends your model where it shouldn't go, heheh
07:23 PM roycroft: that's what i have, rdtsc
07:23 PM roycroft: an older one
07:23 PM Tom_L: back then i just took my ball mouse there to use
07:24 PM roycroft: https://www.ebay.com/itm/203942740007
07:24 PM roycroft: that's the one i have
07:24 PM roycroft: i highly recommend it for anyone doing 3d modeling
07:25 PM Tom_L: yeah the ones at the votech had the base with a load of buttons etc
07:25 PM roycroft: i don't use any of those buttons
07:25 PM roycroft: i don't try to emulate a standard mouse or do anything fancy
07:25 PM roycroft: just zoom, pan, and rotate
07:25 PM rdtsc: https://www.amazon.com/connexion-SpaceExplorer-Navigation-Interface-3DX-700026/dp/B000LB5IXC
07:26 PM Tom_L: https://3dconnexion.com/us/product/spacemouse-pro-wireless/
07:26 PM roycroft: that looks way too fancy for me
07:26 PM roycroft: that amazon one
07:26 PM bjorkintosh: I really had high hopes for VR goggles.
07:26 PM bjorkintosh: but. that's what I get for hoping too much.
07:27 PM roycroft: the one tom_l linked to as well
07:27 PM roycroft: i can be a bit dyslexic, and that translates into pushing the wrong button sometimes
07:27 PM roycroft: so keeping things simple is best for me
07:27 PM rdtsc: they work in linux fine, with a bit of tinkering under the hood
07:27 PM Tom_L: after i finished i heard a few were starting to use them
07:28 PM rdtsc: supported in FreeCAD :)
07:28 PM roycroft: speaking of which, i just upgraded freecad on my imac to version 1.0.0
07:28 PM roycroft: it's only taken 22 years for a real release :)
07:28 PM Tom_L: how is the post on it for linuxcnc?
07:28 PM rdtsc: a huuuuuuuge jump for anyone still on the last official 0.22 release lol
07:29 PM roycroft: it's supposed to be decent, tom_l, but i've not used it
07:29 PM Tom_L: maybe one day i'll take another look at it
07:30 PM Tom_L: i don't really need it though
07:30 PM Tom_L: my old cad cam and i are well acquainted
07:30 PM rdtsc: that's the best
07:30 PM * roycroft was on 0.18
07:31 PM Tom_L: and it is full 3d
07:31 PM roycroft: the macos releases tended to be fairly unstable
07:31 PM lcnc-relay: <skunkworks8841@discord> I have used 1.0 off and on.. it seems ok.
07:31 PM Tom_L: but only does wrapped rotary
07:31 PM roycroft: and keeping a couple or three revs back usually worked best
07:31 PM roycroft: my first task with 1.0.0 is to do a few simple things and to see if it crashes easily
07:32 PM Tom_L: i've probably crashed them all at one point
07:32 PM roycroft: now that it has an official assembly workbench it has the potential to be useful software
07:32 PM Tom_L: catia, sw, acad ...
07:32 PM Tom_L: right
07:33 PM roycroft: freecad on macos usually crashes if you look at it funny
07:33 PM roycroft: it has run much more reliably on linux in the past
07:33 PM roycroft: hopefully that has changed now that it's out of beta
07:33 PM Tom_L: if i did, i'd put it on linux
07:33 PM roycroft: i'll probably wait for 1.0.1 if i want to do something real with it
08:02 PM roycroft: for a good time, uri tuchman has attempted to build a rose engine lathe
08:02 PM roycroft: https://www.youtube.com/watch?v=f5QI5Ou7DlM
08:03 PM roycroft: i'll just say he's not quite ready to engrave faces for 50k euro watches yet
08:03 PM roycroft: but he is always entertaining
08:08 PM xxcoder: lol skipped though it a bit, pretty cool
08:09 PM xxcoder: first geared cvt? https://youtu.be/mWJHI7UHuys
08:19 PM xxcoder: very interesting so far
08:23 PM rdtsc: interesting but fragile and uproven so far. kinda more than bummed that https://www.youtube.com/watch?v=sTHSFncPUCQ never went anywhere.
08:24 PM xxcoder: cvt is not engine but transmission
08:24 PM xxcoder: and video was released yeserday
08:24 PM rdtsc: right, prototype, for bicycle. ingenious idea though.
08:25 PM xxcoder: yeah. I wobder if it will hit off
08:25 PM xxcoder: I would love to have that cvs in tricycle lol
08:25 PM rdtsc: well it's uproven... would like to see it in a trike for sure
08:26 PM rdtsc: *unproven
08:27 PM xxcoder: Im not sure how well it would scale also
08:27 PM rdtsc: one-way needle bearings just seem fragile to me (for anything other than a bike)
08:28 PM xxcoder: I suppose car one would need different setup and design but same concept
08:28 PM xxcoder: maybe even more "arms"
08:29 PM roycroft: as we move to more electric vehicles, the need for a variable gear ratio transmission is less and less important
08:30 PM xxcoder: oh interesting look at 24:00
08:30 PM rdtsc: JT, power switch seems to operate normally; Estop changes color and text once then never again - likely something with "remote" latch.
08:30 PM rdtsc: retiring early, g'night
08:31 PM rdtsc is now known as rdtsc_away
08:31 PM xxcoder: well adding channel to feed, seems fun one
08:33 PM xxcoder: wching one where he explains stocks using toy water gun
08:33 PM xxcoder: https://youtu.be/rA552oVncac
08:52 PM xxcoder: well that was amazing. guy may be annoying but very educational.
08:58 PM Tom_L: they fill em with gas so the oil doesn't foam
09:00 PM xxcoder: isnt gas also imcompressable since liquid?
09:00 PM Tom_L: i'm not sure how much of a void there is
09:00 PM xxcoder: well it seems pressuring gas is plenty to stop the foaming
09:01 PM Tom_L: https://www.youtube.com/watch?v=kSoGt-TsZL8
09:01 PM xxcoder: love that show
09:01 PM Tom_L: @4:00
09:02 PM xxcoder: watching whole thing no spoilers lol
09:06 PM xxcoder: nitrogen gas interesting. pressurized I guess
09:07 PM xxcoder: yeah pretty cool allright. I thought you meant gas as in liquid one powering cars and such lol
09:07 PM xxcoder: I do wonder how pressurized the nitrogen is though. if its sprayed in as liquid then it would warm and have quite high pressure for examplke
09:15 PM Tom_L: A typical gas shock absorber usually has a pressure ranging between 20-30 psi
09:16 PM Tom_L: with the gas (typically nitrogen) being separated from the hydraulic oil by a floating piston within the shock cylinder
09:20 PM xxcoder: thats cool. I guess its been refined since basics was com up with. thanks tom
