12:32 AM sensille: so when i want input filtering i have to use inm instead of gpio?
12:44 AM Bleepshop: sensille: Don't look at me, I'm trying to figure out why hardware GL is screwed with 3 different video cards in my CNC machine.
12:46 AM Bleepshop: Neat kvirc just seg-faulted over there. [12 feet away]
01:13 AM sensille: whoa, inm is expensive is term of gates
01:37 AM sensille: i guess something else is wrong, the code doesn't look that expensive
01:37 AM travis_farmer[m]: G'Morning, it is 2:33am here. i woke up so early, mostly, because my room was very cold. see, i have website servers in my room that make a lot of heat, so i had a fan in the window to cool the room down, so i could sleep. long story short, i forgot to turn the fan off once the room cooled down. it was 41F in there... so i came downstairs, and here i am. :-)
01:38 AM -!- #linuxcnc mode set to +v by ChanServ
02:01 AM Deejay: moin
02:01 AM Deejay: happy new year!
02:03 AM verm__: happy new year!
02:16 AM Deejay: :)
02:23 AM XXCoder: happy new year
02:46 AM travis_farmer[m]: what a way to start the new year... my cableTV went out, and therefore my internet and phone... :-(
02:46 AM XXCoder: doh
02:46 AM XXCoder: well happy new year
02:47 AM travis_farmer[m]: happy new year to you as well :-)
02:51 AM travis_farmer[m]: just happened to think... i wonder if my new spindle will come with a tool holder, and if so, i wonder what collet size it takes... i know it is a BT30 (ATC)... i may have to buy at least one to start, so i can use the spindle, but with funds running very low, i hate to buy something that it comes with. i mean, i will have to pick up several later to take advantage of the ATC, but for just starting i can get by with 1.
02:52 AM XXCoder: bt30 isnt too expensive on aliexpress, but you probably have to dial in tools due to error
02:53 AM XXCoder: looks like $15-$20 for more average ones
02:53 AM travis_farmer[m]: "dial in tools due to error" ??
02:53 AM XXCoder: facemills or sets cost a bit more
02:53 AM XXCoder: yeah its made very cheaply in china so its probably bit iffy on tolences
02:53 AM XXCoder: so tool might not be stright down
02:53 AM travis_farmer[m]: ahh, ok
02:54 AM XXCoder: facemill $30, $50 for boring head
02:54 AM XXCoder: not too expensive
02:54 AM travis_farmer[m]: it is a woodworking router table
02:55 AM XXCoder: you probably still want facemill but boring probably not
02:55 AM XXCoder: or maybe flycutter if its larger area
02:57 AM travis_farmer[m]: i have several CNC router bits, mostly 1/2" and 1/4" shanks. i have a surfacing bit as well. Amana(sp?) Tools brand bits (so far)
02:58 AM XXCoder: you'll have fun trueing your spindle
02:58 AM XXCoder: pretty important to do that
02:58 AM travis_farmer[m]: i am sure.
02:59 AM travis_farmer[m]: i need to get a tramming gauge at some point
02:59 AM XXCoder: can always make one
02:59 AM XXCoder: make spindle hold a rod, then you can attach a rod horzional to it and have dial indictor at end
03:00 AM XXCoder: even better if you can do both sides at once
03:00 AM travis_farmer[m]: the gauges are somewhat cheap i think...
03:00 AM XXCoder: or very cheap from aliexpress
03:01 AM XXCoder: usually metric and around $15?
03:01 AM travis_farmer[m]: https://www.ebay.com/itm/394362729622 or maybe not as much as i think...
03:01 AM XXCoder: yeah special tool gonna be expensive
03:02 AM XXCoder: https://www.ebay.com/itm/115647640344
03:02 AM XXCoder: with 2 cheaper dial indictors it would be around 100 usd total
03:03 AM XXCoder: but you can go cheaper if you make your own mount
03:03 AM XXCoder: just ensure it does not flex
03:04 AM XXCoder: https://www.ebay.com/itm/203961794526 looks virtually 3d printed, if not literally
03:04 AM travis_farmer[m]: how cheap?
03:05 AM travis_farmer[m]: dang, that is cheap!
03:05 AM XXCoder: nicer ones is designed to avoid flex
03:05 AM XXCoder: those cheaper ones dunno, I bet you can make more rigid ones easy
03:06 AM XXCoder: you could just use cheap crap wood to dial it in some ways too
03:06 AM XXCoder: just use facemill
03:06 AM XXCoder: you can see steps if its slanted on one axis, bowling for other axis
03:07 AM XXCoder: adjust till its as perfectly flat as you can feel and care about
03:09 AM travis_farmer[m]: yeah, though at this point, i don't have $100... will be a future purchase, for sure. i can square it by rough measurement while just testing
03:09 AM XXCoder: facemill is cheaper than 2 indictors and holder for em
03:09 AM XXCoder: and it remains useful
03:09 AM travis_farmer[m]: dialing it in using the facemill sounds best for now
03:09 AM XXCoder: smaller tools you can still use
03:09 AM travis_farmer[m]: yup
03:09 AM XXCoder: just more work
03:13 AM travis_farmer[m]: i still have to figure out how i am going to mount it (the new spindle). may have to make a adaptor plate out of aluminum... though i have a large piece of 1/4" or 3/8" plate steel... just have the dissimilar metals issue
03:15 AM XXCoder: not sure also
03:15 AM travis_farmer[m]: will know more when it arrives...
03:17 AM XXCoder: good idea yeah
03:27 AM travis_farmer[m]: buying some proper T-nuts fitted for my machine extrusions... they have a M6 thread... i don't deal with metric much, that 6mm?
03:27 AM travis_farmer[m]: googled it, 6mm :-)
03:27 AM pere: inspired by <URL: https://yewtu.be/watch?v=jmKUV3aNLjk >, I am writing a LinuxCNC user space component to publish pins to MQTT.
03:27 AM travis_farmer[m]: that would be neat, pere
03:28 AM pere: at the moment it can only handle float pins, as I lack a good notation to specify pin type for dynamic pins.
03:31 AM travis_farmer[m]: bit pins can be converted at each end. 1.0 = true, 0.0 = false, maybe
03:31 AM travis_farmer[m]: that way they are sent as a float
03:32 AM travis_farmer[m]: though that would mean LCNC would have to do the conversion, so maybe not...
03:35 AM travis_farmer[m]: http://linuxcnc.org/docs/2.9/html/hal/components.html 1.6.3 "type conversion" so maybe LCNC can do the conversion
03:36 AM pere: the issue at hand is that I use names=pin1,pin2,pin3,... and do not know how to best specify each pin type.
03:38 AM travis_farmer[m]: if every pin is set as a float, then the conversion components i referenced can convert most any input to a float. then whatever software at the other end of the MQTT just has to convert it back to what it is supposed to be.
03:43 AM travis_farmer[m]: so in the HAL config file, if you need to convert a bit pin to a float pin to enter your MQTT component, you "loadrt conv_bit_float..." and assign the bit pin you want to monitor to the input of the conversion, and the output of the conversion goes to the input pin of your MQTT component. am i making sense? i only have had one cup of coffee... ;-)
03:45 AM travis_farmer[m]: that way, your MQTT component only needs to handle float pin definitions
03:45 AM travis_farmer[m]: it is messy, but it would work
03:56 AM pere: <URL: https://github.com/petterreinholdtsen/linuxcnc/tree/comp-mqtt-client > is the fairly untested code so far.
03:57 AM pere: I believe it would work too, expect for strings. but it is the messy part I want to avoid, just need to come up with a way to do it.
03:57 AM pere: Perhaps names=pin1[type],pin2[type] or something like that is a good approach.
04:09 AM travis_farmer[m]: Hmmm, python isn't my strong-suit. the simple comps i wrote were in C/C++. in C/C++, i would make an array of each pin type available. so like if you had pin_float[count], pin_string[count], ... but i am not sure how that would work in python
04:18 AM pere: note, I am only talking about the HAL configuration notation, not the code internals. considered C/C++ to be able to make a .comp with emdedded documentation, but decided the extra work to handle mqtt libraries were not worth the effort.
04:19 AM pere: this way the package do not need to build depend on a mqtt library, and the resulting deb do not end up pulling in new dependencies. only those using the component need to install paho.
04:19 AM travis_farmer[m]: "but decided the extra work to handle mqtt libraries were not worth the effort." i can agree on that point
04:20 AM pere: In python I could represent this using a hash/associative array, similar to json notation: pins = { 'name' : 'pin1', 'type' : 'bit'} or similar.
04:40 AM pere: is runtime and ini file MACHINE value available from HAL? Or perhaps some other python library?
04:56 AM JT-Cave: morning
06:03 AM saquzi: What would be the most cost efficient and easiest way to get more inputs for gray scale encoder inputs using 7i97? I need 7i74 or 7i44 for the rest sserial 8i20 communication. Could i connect the boards via sserial like PC - 7i44 - 7i97, 8i20 (x3) and use the 7i97 P1 expansion connector for the encoder inputs?
06:18 AM * travis_farmer[m] dines on a plate full of bacon :-)
06:22 AM * pere imagines dining on a plate made of bacon. :)
06:29 AM Tom_L: morning
07:52 AM boozeman[m]: one question about mesact
07:55 AM boozeman[m]: i have firmware files on /lib/firmware/hm2 with directory rights drwxr-x-r-x and files rw -rw-r--r-- Starting mesact on normal user i can not choose firmware. Only sudo mesact activates the dropdown. I have 7i96S_d firmware installed, so this is not a problem, but just wondering. I remember that 0.7.x version works with normal account.
07:56 AM boozeman[m]: * i have firmware files on /lib/firmware/hm2 with directory rights drwxr-x-r-x and files rw -rw-r--r-- . When starting mesact with normal user I can not choose firmware. Only sudo mesact activates the fw-dropdown. I have 7i96S_d firmware already installed, so this is not a problem, but just wondering. i am remembering that 0.7.x version worked with normal account.
08:07 AM sensille: what a nasty trap. testing tool sensor overtravel estop. works. but how to move up the spindle now?
08:07 AM sensille: the new steppers don't have a handwheel
08:11 AM JT-Cave: mesact doesn't use firmware from /lib/firmware/hm2
08:12 AM JT-Cave: mesact used to store firmware in /usr/lib/libmesact/name of board
08:13 AM boozeman[m]: ok
08:14 AM JT-Cave: to make mesact acceptable to include in Debian I had to remove the firmware because I didn't supply the source and now firmware is downloaded and installed in ~/.local/lib/libmesact/
08:14 AM JT-Cave: so if your using the 1.2.0 version you need to select a board then Download > Firmware
08:16 AM boozeman[m]: just downloading 1.2.0, thanks for info
08:19 AM JT-Cave: you're welcome
09:06 AM Tom_L: JT-Cave, build or wait for a pdf change?
09:07 AM sensille: i'm afraid now i have to choose a GUI ...
09:21 AM Tom_L: JT-Cave, you might consider looking at /usr/lib/libmesact and ask the user if they want to remove old version files
09:21 AM Tom_L: if they're upgrading from an old version
09:21 AM Tom_L: (i did it manually)
09:22 AM Tom_L: or show how to do it manually for them
09:22 AM _unreal_: https://github.com/berin-aquaquad/orange-pi-5 thoughts on my beta design for the micro desktop case for the OPI5?
09:22 AM _unreal_: I designed it with a VERTICLA style MB
09:40 AM JT-Cave: Tom_L, wait a while... I wonder how to upgrade and remove the firmware files???
10:23 AM Tom_L: check to see if the dir is there
10:23 AM Tom_L: i doubt anybody would have added any files there
10:24 AM Tom_L: then cd /usr/lib sudo rm -r libmesact
10:24 AM Tom_L: -R
10:28 AM Tom_L: -R
10:29 AM Tom_L: os.path.isdir('new_folder')
10:29 AM Tom_L: True
10:29 AM Bleep-CNC: Tom_L: 'tar tzvf libmesaact-[date].tar /usr/lib/mesaact' will package them for storage
10:29 AM Tom_L: no real need to keep them
10:30 AM Tom_L: for licensing purposes
10:30 AM Tom_L: he has moved them into the home/user/.local directory
10:32 AM travis_farmer[m]: too bad there wasn't version control on each individual firmware file... then it would be easy to update only changed firmware
10:32 AM Tom_L: not a matter of updating
10:32 AM Tom_L: the source isn't provided so they need to be separate from the deb install file
10:33 AM Bleep-CNC: I'm calling this succcess. It's been running ~8 hours and the histogram looks like an insulin needle. -7.8 / 0.0 / 8.1.
10:33 AM Tom_L: kinda like a debian install non-free
10:33 AM travis_farmer[m]: oh, so it is a one-time pull?
10:33 AM Tom_L: per board
10:34 AM travis_farmer[m]: ok, i see
10:34 AM Tom_L: so it shrinks the install size
10:34 AM Tom_L: very doubtful the end user will have every board
10:34 AM Tom_L: so install the firmware for the one you have
10:34 AM Bleep-CNC: Tom_L: I don't know. Some of these people seem a little OCD. ;D
10:35 AM Tom_L: i have a handfull
10:35 AM * Bleep-CNC whistles innocently.
10:35 AM * travis_farmer[m] is very OCD ;-)
10:35 AM Tom_L: but i try to test with them
10:42 AM travis_farmer[m]: hmmm, been perusing my schematic i have for reference on my machine wiring, and i am finally getting close to REALLY using my 7i80HD-16. :-) glad i didn't go with a board with less I/O :-)
10:42 AM sensille: so nice to be able to use mesaflash with my rv901t :)
10:43 AM Tom_L: travis_farmer[m], i use a chart over a schematic. seemed easier to edit to me
10:44 AM travis_farmer[m]: i edit it in Fusion360 electronics design, so it is fairly simple for me
10:44 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.2/New_Mill_IO_Pinout.pdf
10:44 AM Tom_L: some wire colors change at a connector and that is also noted
10:44 AM travis_farmer[m]: hmmm, i wish Fusion360 let me color the wires...
10:45 AM travis_farmer[m]: i can make notes, i guess
10:45 AM Tom_L: i have made alot of changes to it as i test different things
10:46 AM * travis_farmer[m] posted a file: (47KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/DdNBYqcgxbnVgJCuiCfeozqI/7i80hd-16_connections%20v60.pdf >
10:46 AM travis_farmer[m]: hmmm, that didn't work exactly like i thought...
10:47 AM Tom_L: that's the 'usual' way to do it but i took a different approach
10:47 AM travis_farmer[m]: whatever lets you keep track, is what is good for you :-)
10:47 AM Tom_L: seemed easier to edit a txt file
10:51 AM travis_farmer[m]: i started with EagleCAD, designing, so when Eagle became part of Fusion360, it was a smooth transition for me
10:53 AM travis_farmer[m]: gotta take lunch out of oven :-)
10:56 AM Tom_L: i used to use eagle quite a bit
11:00 AM Tom_L: JT-Cave, do you check the new firmware directory to see if it's there before installing?
11:04 AM Tom_L: meh, nevermind
11:04 AM Tom_L: something i did here...
11:07 AM Tom_L: JT-Cave, an idea on the pdf files... what if you put each one in the same directory as the bit/bin files and installed along with the firmware?
11:07 AM Tom_L: it's still offloaded
11:08 AM Tom_L: that might not work for daughter cards
11:14 AM JT-Cave: Tom_L, before installing measct?
11:16 AM JT-Cave: I think for the pdf files I make an option to download direct from mesa the pdf's they want
11:16 AM JT-Cave: make it like the pushbutton for I/O which looks like a menu with submenus
11:21 AM Tom_L: even better, then you don't have to store them
11:22 AM Tom_L: as long as the link doesn't change
11:24 AM Tom_L: <JT-Cave> Tom_L, before installing measct? ... not sure what you're asking
11:41 AM Bleep-CNC: Other option is have them uploaded to a git where you can controll the URLs.
11:42 AM roycroft: happy new year, folks!
12:14 PM Bleep-CNC: It's over 10 hours with 'latency-histogram --show --nobase --sbins 1000 --servo 25000' running and I'm at -11.3 / 0.0 / 12.4. I think I have a winner.
12:15 PM Bleep-CNC: Tom_L: JT-Cave: Do those look like decent numbers?
12:29 PM JT-Woodshop: what did you do to get the numbers that low?
12:29 PM JT-Woodshop: you can software step with that
12:30 PM JT-Woodshop: oh you raised the servo period way up
12:30 PM travis_farmer[m]: i think he sold his soul to the devil... ;-)
12:35 PM travis_farmer[m]: there, bought 1 BT30 (ER20) tool holder, a retention knob thing, and a set of ER20 collets... officially out of money, but i think i can use what i have coming to at least use the spindle, even if i am doing manual tool changes with it for a while. i think i still have $60 in cash that i can deposit on monday for any small last minute needs. i REALLY need to get some income coming in...
12:37 PM -!- #linuxcnc mode set to +v by ChanServ
12:43 PM * travis_farmer[m] ponders selling his E-drum kit, and 32CH Mackie analog mixer to raise some funds...
12:45 PM travis_farmer[m]: cnc router tables are an expensive hobby... even more expensive if you have plans to make a job out of using one...
12:47 PM roycroft: it takes money to make money
12:47 PM roycroft: and the best way to make $1000 woodworking is to spend $2000
12:48 PM travis_farmer[m]: yeah, true. but i have to sell off all my failed hobbies in order to make money, at this moment.
12:50 PM boozeman[m]: I am still hunting good machine for foam cutter. Lenovo M700 is better than Lenovo M910q (i5 6500t vs. i5 7500t) in latency. Same Debian bookworm with same settings both.
12:52 PM travis_farmer[m]: roycroft: "and the best way to make $1000 woodworking is to spend $2000" i think in this economy, they would be spend $3000 to make $1000 ;-)
12:52 PM travis_farmer[m]: s/they/that/
12:53 PM sensille: does it need a 2.5kW spindle for woodworking?
12:53 PM roycroft: mayhap
12:54 PM roycroft: sensille: a 2.5kw spindle is not that much power for woodworking
12:54 PM roycroft: that's the size on the smaller commercial routers
12:54 PM travis_farmer[m]: yeah, my spindle i have coming is 4.5kw...
12:54 PM roycroft: many of the ones that handle full sheets have 7kw or bigger spindles
12:54 PM sensille: oh, 4.5, not 2.5 ...
12:55 PM sensille: needed for a large DOC?
12:55 PM roycroft: or large area of cut
12:55 PM roycroft: if you're putting a 75mm diameter cutter on the thing you need some power
12:55 PM travis_farmer[m]: mostly for the dynamic load from the change in grain
12:56 PM roycroft: i have a 2.5kw spindle for the router i'm building, which will be small, and i know that the spindle is going to be fairly limiting
12:57 PM roycroft: but it should work for what i plan on doing
12:57 PM roycroft: the alternative is not just a more powerful spindle, but a much more massive machine to handle the bigger spindle
12:58 PM Bleep-CNC: boozeman[m]: Dell Optiplex 390 here. bumped it to 12gb RAM, using onboard video and audio.
01:03 PM boozeman[m]: That ThinkCentre M700 has disabled audio with 20GB memory etc. 37000-47000ns for latency test. M910q peaks sometimes about 70000ns. There's even high difference with the same machine models (I have 8 M700 and 3 M910Q) All tested with the same memory banks and ssd with same bios version and settings.
01:07 PM Bleep-CNC: boozeman[m]: https://imgur.com/a/OqeaRhS
01:07 PM travis_farmer[m]: hmmm, i really need to seek out a better computer for my LCNC... i think i have it set very high on servo period, and it has no hardware graphics, so glxgears really harms the latency. so far, i just ran nothing but LCNC, and haven't had much problem... but i think i could do better on the computer, at some point...
01:08 PM boozeman[m]: That's quite narrow jitter. Mine has somewhate wider 😄
01:09 PM travis_farmer[m]: my servo period is way up at 1100000, lol
01:09 PM Bleep-CNC: boozeman[m]: No Hyperthreading. No VM/VT. xfce for the desktop.
01:10 PM Bleep-CNC: boozeman[m]: lightdm for display manager.
01:10 PM Bleep-CNC: This is the only time I have seen sdev at 0.0 LOL
01:11 PM Bleep-CNC: command line is 'latency-histogram --show --nobase --sbins 1000 --servo 25000'
01:11 PM boozeman[m]: yeah. All disabled, tried with isolcpus=2,3. Debian bookworm, xfce without debian-desktop. All "nonsense" removed, like Cups etc.
01:12 PM Bleep-CNC: boozeman[m]: Turn off HT, turn off VT. You'll apparently lose cores, but it gets a lot smoother.
01:13 PM boozeman[m]: One dump question about wiring. I have Stepperonline DM332T drivers and there enable is on by default (+5vdc) If I want to use it like motors are not enabled when starting linuxcnc, I route enable pin to gnd, yes? Can I use single output for 4 motors in this purpose.?
01:13 PM boozeman[m]: and yes. hyperthreading is of and also all virtualization support. Only multicore support is on
01:13 PM Bleep-CNC: boozeman[m]: Yeah, you should be able to tie all your EN pins to the same line.
01:16 PM Bleep-CNC: This machine dropped from 4 cores showing to only 2 when I turned VT/HT off. But the latency numbers started dropping through the floor after that and adding isolcpus-0,1.
01:17 PM JoseIgnacioRomer: isolcpus is the flex tape of latency
01:17 PM boozeman[m]: I will test tomorrow with that
01:17 PM boozeman[m]: 🙂
01:19 PM boozeman[m]: Cpu governor is set to Performance at the startup. Without it the governor is set to powersave by default. I do not want green Office. I want Nuclear Office! 😄
01:19 PM Bleep-CNC: boozeman[m]: The difference may be that I used JT's 11>13>lcnc guide and am running 13.
01:20 PM Bleep-CNC: boozeman[m]: C-states! Turn that puppy down as far as you can in the BIOS.
01:20 PM boozeman[m]: 13 here too. Some performance drop happened when changing to 6.x RT kernels.
01:20 PM boozeman[m]: Cs disabled from bios too
01:21 PM * Bleep-CNC has reloaded the OS on thisa machine so many times he does it in his sleep.
01:22 PM boozeman[m]: 😄
01:22 PM travis_farmer[m]: i know that feeling, when i first started with LCNC
01:23 PM Bleep-CNC: I've built and rebuilt with different combos of RAM, video cards and settings to get to this point.
01:23 PM Bleep-CNC: All in the last week. LOL
01:24 PM travis_farmer[m]: i just found a computer i could get by with, for using the machine, and used a different hard drive to experiment with
01:24 PM * Bleep-CNC is upgrading from software stepping to a 7i96s.
01:24 PM travis_farmer[m]: welcome to the Mesa gang Bleep-CNC ;-)
01:25 PM boozeman[m]: Finding the good LCNC machine is like The hunt of Atlantis/Graal/Approving cat or wife/Unicorn from the enhanched forest / etc machical creature.
01:25 PM Bleep-CNC: Old machine was a Dell Precision T3400. Ex medical/cardiac imaging workstation.
01:25 PM boozeman[m]: Like I say, the same product models differ each other with same ssd and memory
01:26 PM travis_farmer[m]: yeah, and the computers you think will be great, are far from it lol
01:26 PM Bleep-CNC: Old machine ran fine, just too slow for my tastes.
01:27 PM * Bleep-CNC has been spoiled with decades of RAMDISK and more recently SSDs.
01:28 PM travis_farmer[m]: i have a Asus intel i7 with 32GB ram desktop pc, but i doubt it would make a good LCNC machine...
01:29 PM boozeman[m]: I quess that the RT kernel is always a compromise (I am quessing, I really do not know. When i was compiling the Kernel myself, the version was 2.0.0.36)
01:32 PM boozeman[m]: Haha! Kernel 6.0 notes Named "Hurr durr I'ma ninja sloth" 😄
01:33 PM roycroft: i'm pretty accustomed to computers with at least 16GB of ram these days
01:34 PM roycroft: to the point that i don't bother with the old rule of thumb to allocate 2x as much swap partitioning as physical memory, because most machines i manage these days rarely, if ever, swap
01:34 PM roycroft: the imac i use as my primary workstation nothwithstanding
01:34 PM roycroft: because macos is pretty sucky in many ways, and their web framework is leaky as hell and consumes massive amounts of ram
01:35 PM roycroft: i've never had to reboot a machine so often as i reboot this imac
01:35 PM roycroft: not even windows machines
01:37 PM Bleepshop: I only reboot if the power is out longer than the UPS can handle. LOL
01:37 PM roycroft: i have to reboot my imac a couple times/month or so
01:37 PM roycroft: it has 32gb of ram
01:38 PM Bleepshop: roycroft: Oh. So it wants more does it. LOL
01:38 PM roycroft: web browsers consuming ever-increasing amounts of ram
01:38 PM roycroft: and killing the browser does not release all the memory
01:38 PM roycroft: it doesn't matter which browser - they all use the apple web framework
01:39 PM Bleepshop: roycroft: Same problem with Firefox. Eventually it'll crash the box if I'm not carefull
01:39 PM roycroft: safari is the worst, but any other browser i've tried eventually succombs to memory suckage
01:40 PM roycroft: i've mitigated the problem somewhat by upping the physical memory from 24gb to 32gb, and by replacing the hybrid drive with a high-performance ssd
01:40 PM roycroft: but when it starts swapping, computer life grinds almost to a halt
01:41 PM roycroft: this is a big reason i bought a dedicated cad workstation - running solidworks/autocad in a vm on the imac just got too slow
01:41 PM Bleepshop: roycroft: Ditch the MacOS and install Debian? Debian has installed on every Mac I've thrown it at. ;D
01:41 PM roycroft: debian doesn't have decent apps
01:41 PM roycroft: the thing i like about macos is that is unix with apps
01:42 PM Bleepshop: Nag, Nag, Nag, Gripe, Gripe, Gripe... LOL
01:42 PM roycroft: i'm not griping, actually
01:42 PM roycroft: it's a situation i've found a way to live with
01:42 PM roycroft: the cad workstation helped a lot
01:43 PM roycroft: and i have a couple decent servers in the back room running proxmox pve, and i run most of my vms on those these days
01:43 PM roycroft: i used to have vmware fusion running on my imac 24/7
01:43 PM roycroft: now it fire it up once/month or so
01:43 PM Bleepshop: roycroft: Years ago [right after OSX release] the boss [hardcore fanboi] where I was working wanted to know if I'd consider switching from doing PC repairs to Mac repairs.
01:44 PM roycroft: what is a "mac repair"?
01:44 PM roycroft: mac fanboi mentality is to replace a machine when a newer, shinier one comes out, regardless of how well the current one is running
01:45 PM roycroft: macs are not ever supposed to be in service long enough to require repair
01:45 PM Bleepshop: I thought about it ofr a minute and said "So oyu want me to work on PC hardware running a bastardized BSD? Sure.". Never heard another word about me switching repair tracks. LMAO
01:45 PM roycroft: if they are, then marketing are not doing their job well enough
01:45 PM * roycroft is an avid mac user, and is the anti-mac fanboi at the same time
01:46 PM roycroft: but maybe that will all change soon
01:46 PM roycroft: after all, it's 2023
01:46 PM roycroft: and 2023 is the year of the linux laptop
01:47 PM Bleepshop: I put Apple on my shitlist when they brought out the Macintosh series. It was a total sealed box, consumer-fuck if you were used to the IIc or IIe.
01:49 PM Bleepshop: I could etch boards for a II series in my garage and populate them myself. The Macintrash had no slots, soldered in RAM and needed a screwdriver a foot long to open.
01:49 PM * travis_farmer[m] wonders where all his money went... as he checks status on orders at Amazon and eBay... ;-)
01:50 PM Bleepshop: travis_farmer[m4: It went to corporations after you sucumbed to their blandishments?
01:50 PM travis_farmer[m]: apparently...
01:50 PM roycroft: the original macintosh was great
01:50 PM roycroft: i loved it
01:51 PM roycroft: i had to go out and buy a 24" long #2 phillips screwdriver to open the case on that machine
01:51 PM roycroft: and in the almost 40 years that i've had that screwdriver, it has come in handy more times than one can imagine
01:51 PM roycroft: it's only opened a dozen or so macintoshes in all that time though
01:52 PM roycroft: but if it hadn't been for the macintosh, i probably wouldn't own that screwdriver
01:52 PM roycroft: so kudos, apple, for inspiring me to buy a very useful tool!
01:53 PM XXCoder: orginal maconish was fun
01:53 PM XXCoder: school one come with that physics sim program
01:53 PM XXCoder: played with that a lot
01:54 PM travis_farmer[m]: one of the governors for my state, Maine, once used a grant from microsoft, slated for student laptops, to buy APPLE laptops! and then wondered why no more grants came from microsoft...
01:54 PM XXCoder: ouch lol
01:55 PM roycroft: that seems kind of silly, because apple used to almost give away computers to schools
01:55 PM travis_farmer[m]: no idea, i just remember it from the news
01:56 PM XXCoder: andypugh: you was referenced in one of discord channels. fun lol
01:57 PM XXCoder: your plastic probe thing for mill
01:57 PM roycroft: was this governor baldacci?
01:57 PM travis_farmer[m]: probably microsoft wanted students to not be limited on only one student laptop brand, but the gov' screwed that up
01:57 PM roycroft: or angus king?
01:57 PM XXCoder: likely intent is "any windows laptop" but yeah guy failed on that I guess
01:57 PM travis_farmer[m]: king
01:58 PM travis_farmer[m]: yup
01:58 PM travis_farmer[m]: guy probably didn't even know the difference between windows and mac, LOL
01:58 PM roycroft: that's microsoft's bad, for not stipulating the terms precisely enough
01:58 PM travis_farmer[m]: that too
01:59 PM roycroft: if it was governor king, it was in the steve ballmer days at m$
01:59 PM roycroft: and ballmer is pretty arrogant
02:00 PM roycroft: he probably sincerely believes that all real laptops run windows
02:00 PM roycroft: and anything else is some kind of abomination that need not be discussed or considered
02:00 PM travis_farmer[m]: that has always been my guess
02:01 PM roycroft: i need to decide on whether to make a new jig for my disc sander today
02:01 PM roycroft: or muddle through with my router table
02:01 PM * travis_farmer[m] has never had to dance a jig to make a sander work...
02:02 PM travis_farmer[m]: ;-)
02:02 PM roycroft: i'm a fan of jigs
02:02 PM roycroft: it must be the scottish blood in me
02:02 PM travis_farmer[m]: i have schot blood too
02:03 PM roycroft: i'm almost out of boeshield t-9
02:03 PM travis_farmer[m]: stewart, from my fathers mother
02:04 PM roycroft: my scottish ancestors are from clan geddis
02:04 PM roycroft: geddes, rather
02:05 PM travis_farmer[m]: i am supposedly descended from King James Stewart, or some such thing...
02:05 PM roycroft: the name got morphed to gaddis when they emigrated to the us
02:06 PM * Bleepshop has Picts, Germans and Swedes from Dad's side of the family and Conquistadors and Yaqui on Mom's side.
02:06 PM Bleepshop: No wonder I'm an impatient SOB with anger management issues. LOL
02:06 PM roycroft: sounds about right, given where you are from
02:07 PM roycroft: assuming that where you are is not far from where you're from
02:07 PM roycroft: my ancestry are scottish, english, dutch, and german
02:07 PM roycroft: my grandmother on my father's side was a dar
02:08 PM roycroft: she had no daughters, though, only sons
02:08 PM Bleepshop: On the plus side I can never be called "culturally insensitive" for telling ethnic jokes. :D
02:09 PM roycroft: i wish there was a quantity of boeshield available >4oz and <1 gallon
02:09 PM roycroft: 16oz would be perfect
02:09 PM Bleepshop: I've got an aunt, Spent too much $ in the late 70s/early 80s doing genelogical research because she was so sure she'd find royalty.
02:09 PM roycroft: 32oz would be acceptable
02:09 PM roycroft: almost all of us are related to royalty
02:10 PM Bleepshop: She found it all right. It was James the first in 1628 IIRC holding a death warrant for the entire family. LMAO
02:11 PM roycroft: yesterday, when i moved my winch off the table saw into its temporary home, i did my autumnal cleanup and protection of my table saw, jointer, and thicknesser beds
02:11 PM Bleepshop: Took the wind right out of her sails.
02:11 PM roycroft: and used up my boeshield t-9
02:12 PM roycroft: i really don't want to spend $120 on a gallon of the stuff
02:12 PM roycroft: which will last me at least a decade
02:12 PM Bleepshop: roycroft: Buy more? Brew more? Conjure more? Don't just complain, do something about it. ;D
02:12 PM roycroft: i'm madly searching for a quantity that i would find most suitable
02:13 PM roycroft: but in the end, i'll probably end up buying a couple 4oz bottles
02:13 PM roycroft: i should organize a group buy
02:13 PM roycroft: i'd get a gallon and split it into pints
02:13 PM Bleepshop: roycroft: Hey, I'm finally using up the last 20' of a 2500' roll of shielded SO cable I bought in 2001.
02:13 PM roycroft: that's the right thing to do
02:14 PM roycroft: that works out to $15/pint
02:14 PM roycroft: vs ~$50/pint buying it in 4oz bottles
02:15 PM roycroft: but it looks like 4oz and gallon are the two options
02:15 PM travis_farmer[m]: and 12oz
02:15 PM roycroft: btw, do not EVER buy that stuff in an aerosol can
02:15 PM travis_farmer[m]: oh...
02:15 PM roycroft: i have never once been able to completely empty a can
02:16 PM roycroft: no matter how well i clean it after use, the nozzle clogs over time
02:16 PM roycroft: i only buy it in liquid form now
02:16 PM travis_farmer[m]: what about a gallon for $84?
02:16 PM roycroft: where?
02:16 PM roycroft: the cheapest i've found it is $114
02:17 PM travis_farmer[m]: https://www.infinitytools.com/boeshield-rust-free-rust-stain-remover
02:17 PM roycroft: btw, the "boeshield bicycle chain lubricant" is t-9
02:17 PM travis_farmer[m]: scroll down a bit
02:17 PM roycroft: that's a different product
02:17 PM roycroft: i'm looking for boeshield t-9
02:18 PM travis_farmer[m]: oh, google failed me LMAO
02:18 PM roycroft: boeshield rust free is a good rust removal product
02:18 PM roycroft: but it does not protect like t-9
02:18 PM roycroft: i use wd-40 for rust removal
02:19 PM roycroft: i lightly coat the surface with it, then use a green scotch-brite pad on a rotary sander to clean up the surface
02:19 PM roycroft: i wipe down with acetone after to remove the wd-40
02:19 PM roycroft: then i heat the surface until it's fairly warm, and then apply the boeshield t-9
02:20 PM roycroft: heating the surface both ensures that it's dry and helps open the pores in the cast iron, so it will absorb the boeshield better
02:21 PM travis_farmer[m]: yeah, i usually just scrub with wd-40, and then acetone to remove, then leave it... for long term storage, i spray with wd40, and lay plastic on top to keep the dust off...
02:22 PM roycroft: i'd have surface rust within minutes if i left the cast iron bare like that after the acetone cleaning
02:23 PM roycroft: but i live in an area where the humidity is >90% for much of the year
02:23 PM travis_farmer[m]: maybe thats why we do it every day...
02:23 PM roycroft: i would recommend you try boeshield t-9
02:23 PM roycroft: i've tried many different ways of protecting cast iron beds over the years, and that has worked the best for me
02:24 PM travis_farmer[m]: may try it when i can afford to buy some
02:24 PM roycroft: and it will dry completely, so it won't transfer anything to your materials
02:24 PM roycroft: i'm about to order a couple 4oz bottles
02:25 PM roycroft: and i might get another sure shot sprayer to pad the order so can get free shipping
02:26 PM XXCoder: roy really? tacoma its dry pretty much most of year lol
02:26 PM travis_farmer[m]: is it free shipping if you have to spend more to get it? ;-)
02:26 PM XXCoder: kinda inverse of most of world humidity pattern kinda
02:27 PM roycroft: our seasonal humidity is so different that most folks don't even acknowledge it
02:28 PM roycroft: i have never seen a discussion of seasonal wood movement that does not state unequivocally that wood in an indoor setting expands in the summer due to high humidity, and shrinks in the winter due to low humidity
02:28 PM roycroft: it is the exact opposite here
02:29 PM XXCoder: yeah
02:29 PM Tom_L: really?
02:29 PM XXCoder: fun isnt it
02:29 PM Tom_L: all the rain?
02:30 PM XXCoder: tom when I was young, we could have summer rains
02:30 PM XXCoder: not like that lately. but biome is rainforst
02:31 PM roycroft: our rainy season is in the winter, where it's in the summer in most of the country
02:31 PM roycroft: and our climate is rather mild
02:31 PM roycroft: so we don't rely on hvac as much as most of the country
02:32 PM XXCoder: yeah. it used to rain year around, and more in winter
02:32 PM roycroft: back east, not only is it fairly dry in the winter, central heating is heavily used, which tends to dry the interior air more than outdoor air
02:32 PM XXCoder: nowdays summers dont get rain :(
02:32 PM roycroft: i'm trying to decide whether i shold get a steel sure shot sprayer or not
02:33 PM roycroft: i have steel ones for acetone and lacquer thinner, and they're fine
02:33 PM roycroft: but the one i want to get now will be for denatured alcohol
02:33 PM roycroft: which tends to absorb a bit of water
02:33 PM roycroft: i may need to get an aluminium one for that
02:33 PM roycroft: which costs more
02:33 PM Bleep-CNC: roycroft: Get a stainless one?
02:34 PM roycroft: they don't make a ss one
02:34 PM roycroft: and if they did, i'm sure it would cost over $100
02:36 PM roycroft: $73 for the aluminium one vs $54 for the steel one
02:37 PM roycroft: and the aluminium one has a capacity of 16oz, vs 32oz for the steel one
02:37 PM roycroft: this is probably why i don't have one yet
02:45 PM roycroft: folks say the aluminium ones corrode with denatured alcohol
02:46 PM roycroft: but they also say that the seals fail quickly when filling the steel ones with solvents
02:46 PM XXCoder: cant coat inside with stuff?
02:46 PM XXCoder: something that dont go away with ipa but protects alum
02:46 PM roycroft: and i've had my steel ones with acetone and lacquer thinner for years with no problems
02:46 PM roycroft: i'm thinking i'll just get a plastic spray bottle for now
02:47 PM roycroft: https://www.amazon.com/Pre-Labeled-GHS-Spray-Bottles-Denatured/dp/B07H7RBGHR
02:47 PM roycroft: that should be fine
02:47 PM roycroft: and if it fails, it's not expensive
02:47 PM XXCoder: theres even cheaper ones but yeah
02:48 PM roycroft: oh, except that one has $9 shipping
02:48 PM roycroft: so i'll get something else
02:48 PM travis_farmer[m]: happened to think, my new spindle says to not change the tool while the spindle is still spinning down. is there a way to pause in my M6 macro, and wait for the spindle to be fully stopped?
02:48 PM * JT[m]1 uploaded an image: (212KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/KFNpheNFmJeIzRrGSeznHgLs/20230101_144802.jpg >
02:49 PM XXCoder: wow nice
02:49 PM roycroft: you can add pauses to gcode
02:49 PM XXCoder: I guess bottom is next?
02:49 PM XXCoder: spindle dont have brake?
02:49 PM roycroft: but, perhaps more useful would be to program a spin-down time on your vfd
02:50 PM roycroft: and have the macro "sleep" for that long plus a few seconds
02:50 PM travis_farmer[m]: yes, but automated pauses? maybe XX, i don't know
02:50 PM XXCoder: theres definitely gcodes for just waiting x seconds
02:50 PM roycroft: i'm not a gcode expert, but i'm almost certain you can tell it to pause for a set period of time
02:51 PM XXCoder: if im wrong, you could make it move a inch for a minute
02:51 PM travis_farmer[m]: that is what i am scanning the docs for now, XX
02:51 PM XXCoder: but not best, and im pretty darn sure theres pause
02:52 PM travis_farmer[m]: M66, wait on input... not that i guess...
02:53 PM JT-Cave: G4 is dwell
02:53 PM roycroft: yeah, g4 p20000 will pause for 20 seconds
02:54 PM roycroft: and then auto-resume
02:54 PM travis_farmer[m]: there we go, thanks JT
02:54 PM XXCoder: nice
02:54 PM roycroft: jt-cave: i took some pics of the disc sander yesterday while i was doing some maintenance work in the ship
02:54 PM roycroft: shop
02:55 PM roycroft: roycroft.us/Disc-Sander
02:55 PM roycroft: i'm thinking of making a circle jig for it today
02:55 PM roycroft: and btw, you asked about the miter slot that's perpendicular to the disc on yours
02:55 PM roycroft: that would be perfect for a circle jig
02:56 PM XXCoder: square jig is interesting
02:56 PM XXCoder: way to sand and still ensure 90 degree
02:56 PM roycroft: yes
02:57 PM XXCoder: whats guide table for?
02:57 PM XXCoder: I see it has edge
02:57 PM roycroft: look at the kumiko jig pics
02:57 PM roycroft: they use it
02:57 PM XXCoder: ahh
02:57 PM XXCoder: so basically any angle?
02:57 PM roycroft: for kumiko i need to make little pieces of wood that have precise lengths and the ends need to be at precise angles
02:57 PM roycroft: yes
02:58 PM roycroft: so i use the walnut strip in the jig to adjust the length
02:58 PM roycroft: and the angle is fixed by the jig
02:58 PM XXCoder: nice
02:59 PM roycroft: the square and miter plates have adjustment slots so that i can most of the disc, evening out the wear
02:59 PM roycroft: can use, rather
03:03 PM ZincBoy[CAON][m]: Any ideas why the global #<_feed> variable seems to be always 0 in a remapped gcode call?
03:04 PM roycroft: i just realized that the boeshield ships free no matter what, so i don't need to pad the order
03:04 PM roycroft: i'll get ahold of the sure shot folks on tuesday and ask them about ethanol
03:04 PM ZincBoy[CAON][m]: Things like #<_x> and #<_absolute> work fine, but #<_feed> always seems to be zero
03:04 PM Bleep-CNC: JT-Cave: Looks fantastic but aren't you getting a little fancy with the dinnerware for the chickens? ;D
03:04 PM JT-Shop: nice jigs, got a photo of a circle jig
03:04 PM Tom_L: ZincBoy[CAON][m], may be a -devel question
03:06 PM Tom_L: gives the optica illusion of not being round
03:07 PM roycroft: i'm working on a design for one now
03:08 PM roycroft: i think i'm going to make one today
03:08 PM Bleep-CNC: roycroft: Check the dollar stores. The ones here have aluminum spray bottles for <$5.
03:08 PM roycroft: the bottle isn't an issue
03:08 PM roycroft: it's the o-rings/seals
03:09 PM roycroft: if they're rubber they will foul and quickly fail in the presence of ethanol
03:09 PM roycroft: if they're viton they will be fine
03:09 PM Bleep-CNC: roycroft: Viton O-ring set from HF and re-ring it? Be creative. LOL
03:10 PM roycroft: IF that's the only rubber part
03:10 PM Bleep-CNC: I really need to stiffen this console mount up. You typed 3 sentences in the time it took me for 1.
03:10 PM roycroft: and i have viton o-ring kits in both us customary and metric sizes
03:14 PM Tom_L: ZincBoy[CAON][m], does it make a difference if it's local or global? http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Named_Parameters
03:15 PM ZincBoy[CAON][m]: I am trying to use the #<_feed> global named parameter. The other ones I used seem to work fine and have the expected values. I just ran into this as I started trying to read the feedrate. This is in a re-mapped custom gcode .ngc file.
03:16 PM Tom_L: also https://linuxcnc.org/docs/html/remap/remap.html#_f_set_feed_code_setfeed_prolog_code_and_code_setfeed_epilog_code
03:19 PM Bleep-CNC: Anybody know why Gmoccapy would throw hal_gremlins and refuse to show a preview?
03:26 PM Tom_L: ZincBoy[CAON][m], is there a list of named parameters?
03:27 PM ZincBoy[CAON][m]: In: http://linuxcnc.org/docs/stable/html/gcode/overview.html#gcode:predefined-named-parameters
03:28 PM Tom_L: sure it's not _feedrate?
03:28 PM JT-Woodshop: http://linuxcnc.org/docs/2.9/html/gcode/overview.html#sub:system-parameters
03:29 PM ZincBoy[CAON][m]: Found the problem. I had a G94 in my modal storage function that did not have a feedrate set. This cleared the feedrate in the rest of the subroutine. Adding a F code to reset the value after the G94 fixes the issue.
03:29 PM Tom_L: ok
03:29 PM JT-Woodshop: if F is not set then #<_feed> should return 0
03:29 PM JT-Woodshop: there you go
03:31 PM ZincBoy[CAON][m]: Yes, F was set before the call but the G94 clears the F value so it needs to be reset 🙂 PEBKAC
03:31 PM Tom_L: more common the older you get
03:50 PM travis_farmer[m]: Hmm, been rocking out to music in my headphones, and doing research on some sort of ATC compatible dust collection shoe... didn't realize it was so late in the day already... :-)
03:51 PM Bleep-CNC: Shouldn't the pyvcp go away after I close out lcnc?
03:51 PM XXCoder: travis_farmer[m]: I saw interesting system where vacuum system for collection is on its own seperate z
03:51 PM XXCoder: one you manually set
03:51 PM * Bleep-CNC has a "Spindle Speed" window cluttering up his desktop.
03:52 PM XXCoder: so it is always at good height to clean chips
03:52 PM travis_farmer[m]: sounds interesting XX
03:53 PM JT-Woodshop: it just dawned on me what roycroft meant by the perpendicular slot is for circle jig
03:54 PM travis_farmer[m]: sounds logical
04:11 PM JT-Woodshop: Feed Rate Mode It is an error if: A new feed rate is not specified after switching to G94 or G95
04:14 PM Tom_L: what do lathes use most?
04:14 PM Tom_L: for constant surface speed
04:15 PM Bleep-CNC: CaptHindsight: Greetings Feel like chasing hal_gremlins?
04:19 PM * Bleep-CNC is having issues with gmoccapy.
04:19 PM JT-Woodshop: must be broken... I don't think anyone here uses it
04:22 PM solarwind: https://www.omc-stepperonline.com/e6-series-400w-ac-servo-motor-kit-3000rpm-1-27nm-17-bit-encoder-ip65-e6-rs400h2a2-m17s -- I really wonder what the actual accuracy of the magnetic encoder is
04:22 PM solarwind: 17 bit is very high resolution, but I can't imagine that the accuracy is anywhere near that
04:23 PM solarwind: But maybe that's not important, as long as the precision is actually 17 bits and it can reliably sense the change in position over even a few bits
04:23 PM solarwind: Time to order some very expensive "samples"...
04:25 PM * travis_farmer[m] signs out, as for some reason he no longer gives a damn about life anymore... people suck...
04:25 PM unterhaus: I wonder why I bought any usb asp
04:27 PM ZincBoy[CAON][m]: Most magnetic encoders will specify the accuracy as a % error or in ENOB (effective number of bits). It will almost always be less accurate than the resolution but the higher resolution is great for closing the servo position loop.
04:28 PM Bleep-CNC: solarwind: I was looking at some cheap ones that were 1024 ppr
04:29 PM solarwind: Bleep-CNC Yeah 4096 counts is pretty damn good. Most of the steppers from stepperonline have optical encoders which I've found to be excellent
04:29 PM ZincBoy[CAON][m]: An encoder with 20bit resolution might have an enob of 14 or 15 bits.
04:29 PM Bleep-CNC: These are the AS5600 based ones.
04:29 PM solarwind: I'm not sure why they specify in "ppr", the "counts" is the actual resolution
04:30 PM solarwind: each transition gives you information
04:30 PM solarwind: ZincBoy[CAON][m] yeah I'm trying to find the datasheet for these. Really, even 12 bit effective is more than enough for CNC purposes
04:33 PM Bleep-CNC: Yeah, I'm looking at putting 400 - 800 count on my steppers that way it'll read the stepper rotation and can pseudo-read external applied loads.
04:34 PM ZincBoy[CAON][m]: Since they are a 17bit raw sensor, I would expect 12bit would be reasonable. I have seen 18bit sensors with 13bit absolute accuracy and that would be more than enough. I would think that these would be fine for cnc use.
04:35 PM ZincBoy[CAON][m]: All of those cheap drive/servos seem to use the same 17bit encoder so if you can find the datasheet for one it will probably apply to all.
04:35 PM solarwind: Time to order these as well as one of these https://www.automationtechnologiesinc.com/products-page/ac-servo-motors/ac-brushless-servo-motor-and-driver with a 23 bit absolute optical encoder
04:35 PM solarwind: Couple the shafts and measure the actual accuracy
04:37 PM solarwind: I'm just impressed that stepperonline has actual 4000 count optical encoders on their steppers for < $50 CAD
04:37 PM solarwind: it's hard to find just the encoder for that price
04:37 PM ZincBoy[CAON][m]: You will need something pretty accurate to get to the 12bit range.
04:38 PM * ZincBoy[CAON][m] uploaded an image: (3534KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/yRdciJFwmRQarUgEtXiKwrmU/IMG_1451.JPEG >
04:38 PM ZincBoy[CAON][m]: Something like this:
04:39 PM ZincBoy[CAON][m]: I am still looking for the angular measurement optics... I have the linear, straightness, and square optics so can measure in the nm range.
04:52 PM roguish[m]: ZincBoy[CA, ON]: measure angles.... https://en.wikipedia.org/wiki/Autocollimator
05:00 PM ZincBoy[CAON][m]: Yes, I am looking for one of these though: https://www.keysight.com/ca/en/product/10770A/angular-interferometer.html
05:00 PM ZincBoy[CAON][m]: 0.006 arc sec resolution 🙂
05:03 PM CaptHindsight[m]: solarwind: is 17 bits or 23 bits the new years resolution?
05:09 PM CaptHindsight[m]: 0.001666 mdeg = 0.006 arc sec resolution
05:11 PM x__ is now known as micges
05:12 PM CaptHindsight[m]: https://www.newport.com/f/rga-direct-drive-rotation-stages?q=:ranking-desc:isObsolete:false:-excludeCountries:US:suppress:false:motorized-rotation-stages-minimumIncrementalMotion:0.01%20mdeg:npCategory:direct-drive-rotation-stages
05:12 PM CaptHindsight[m]: ZincBoy[CA, ON]: accurate enough to be useful for ^^
05:15 PM CaptHindsight[m]: Bleep-CNC: nope, sorry, that sounds like software
05:18 PM CaptHindsight[m]: solarwind: did you ever her back about the number of poles for each motor?
05:22 PM Tom_L: JT-Shop, got a link to your debian img? may test it out
05:22 PM CaptHindsight[m]: s/her/hear/
05:24 PM Bleep-CNC: CaptHindsight[m]: Yeah, It's a rendering issue I think. Going to install blender in a bit to test.
05:27 PM roycroft: i am confused
05:28 PM roycroft: mcmaster have 1/4"-32 unf tap sets and 1/4"-32 unef tap sets
05:28 PM roycroft: actually, i think i am not confused
05:28 PM roycroft: i think mcmaster are confused
05:29 PM roycroft: and they are selling something that does not exist
05:31 PM JT-Cave: Tom_L, https://github.com/jethornton/rpi4
05:31 PM Tom_L: roycroft, unef is a thing
05:31 PM Tom_L: JT-Cave, i'll try it on a spare sd
05:31 PM JT-Cave: ok, thanks
05:31 PM Tom_L: comes with lcnc installed?
05:32 PM JT-Cave: that's the lcnc deb
05:32 PM JT-Cave: https://github.com/jethornton/rpi4/releases/download/1.0/linuxcnc-uspace_2.9.0.pre1_armhf.deb
05:32 PM JT-Cave: I'll make a arm64 in a day or three
05:33 PM Tom_L: not an os?
05:33 PM Tom_L: with lcnc preinstalled?
05:34 PM Tom_L: ok
05:34 PM JT-Cave: no just a deb of lcnc
05:34 PM Tom_L: ok, just making sure what i'm testing :)
05:36 PM roycroft: yes, tom_l
05:36 PM roycroft: and 1/4"-32 is a unef thread
05:37 PM roycroft: but 1/4"-28 is the unf thread
05:38 PM roycroft: https://www.mcmaster.com/2521A211/
05:45 PM * JT-Cave calls it a day
05:46 PM roycroft: i'm working on a design for a circle jig for the disc sander that will be able to micro-adust with a granularity of around 0.001"
05:46 PM roycroft: maybe it will be 0.002" in the end
05:46 PM roycroft: but it will still be pretty fine
05:49 PM CaptHindsight[m]: how useful is a centerless disc sander?
05:49 PM roycroft: the center of the disc is useless
05:50 PM CaptHindsight[m]: no it might be open for a reason
05:51 PM CaptHindsight[m]: https://en.wikipedia.org/wiki/Centerless_grinding#/media/File:Centerless_grinding_schematic.svg like this only with sanding discs
05:58 PM CaptHindsight[m]: 1/4-32 is available as a UNF and as a UNEF
05:59 PM CaptHindsight[m]: if you don't like it, write to your local thread lord and ask for help
06:04 PM * roycroft suspects that #10-32 would work for his application, and should perhaps go with the more common thread size
06:05 PM unterhaus: use common thread sizes, don't encourage people to make the weird sizes
06:06 PM roycroft: i would not call a unef thread "weird"
06:06 PM roycroft: it's just uncommon
06:07 PM roycroft: if i were cutting a 1/4"-31 thread that would definitely be weird
06:08 PM CaptHindsight[m]: https://torqbolt.com/unef-unified-national-extra-fine-thread-dimensions-specifications vs https://torqbolt.com/unf-unified-national-fine-thread-dimensions-specifications
06:09 PM CaptHindsight[m]: same proportions and angles
06:10 PM CaptHindsight[m]: 1/4" is absent from the UNF list
06:10 PM roycroft: 1/4" is not on the unf list at all
06:10 PM roycroft: that chart is defective
06:10 PM -!- #linuxcnc mode set to +v by ChanServ
06:10 PM roycroft: 1/4"-28 unf is a defined thread size
06:11 PM CaptHindsight[m]: 1/4" - 28 is in ANSI B1.1
06:11 PM roycroft: i have heaps of fasteners with that thread
06:11 PM CaptHindsight[m]: roycroft: so
06:12 PM CaptHindsight[m]: maybe India doesn't use 1/4"
06:12 PM CaptHindsight[m]: does it really matter as long as it works?
06:13 PM roycroft: https://en.wikipedia.org/wiki/Unified_Thread_Standard
06:13 PM roycroft: teh wikipedia have it right
06:13 PM CaptHindsight[m]: are you willing to contact McMaster and express your outrage?
06:14 PM roycroft: i may drop them a polite email pointing out that there is an error on thier website
06:14 PM roycroft: i'm not outraged by any means
06:15 PM roycroft: i was momentarily confused, until i realised that they are the ones who are confused
06:15 PM CaptHindsight[m]: be sure to keep us updated on that issue
06:16 PM CaptHindsight[m]: did it really matter that much?
06:21 PM CaptHindsight[m]: solarwind: do you have a link to the Stepper Online 4000 count encoder for $50
06:58 PM * Bleepshop pokes solarwind
06:59 PM Bleepshop: solarwind: Dish with the link dude. I'm interested in those encoders too. LOL
07:06 PM Bleepshop: CaptHindsight[m]: All i can find through them is 1000 count AB or ABZ units. https://www.omc-stepperonline.com/1000-cpr-optical-rotary-encoder-abz-3-channel-id-5mm-w-shielded-cable-hkt32-hkt3205-302g-1000bz3-5e
07:35 PM _unreal_: man every channel is quiet....
07:35 PM _unreal_: except for this one
07:40 PM CaptHindsight[m]: Bleepshop: I think they confuse 1000 and 4000 due to pulses vs counts
07:40 PM CaptHindsight[m]: But maybe he found others
07:52 PM Bleepshop: Anybody here using Gmoccapy with 13?
08:05 PM CaptHindsight[m]: Bleepshop: it starts here in Sid with a couple errors
08:05 PM CaptHindsight[m]: but the GUI does run in the sim
08:06 PM CaptHindsight[m]: the backplot window has remnants of the GUI on the desktop behind it
08:08 PM Bleep-CNC: CaptHindsight[m]: You're getting "raise error.NullFunctionError( OpenGL.error.NullFunctionError: Attempt to call an undefined function glutInit, check for bool(glutInit) before calling " ?
08:09 PM Bleep-CNC: That's the first error I'm getting.
08:09 PM Bleep-CNC: It seems to be related to glade-gtk2 and the fact that my gmoccapy.glade file is AWOL.
08:10 PM CaptHindsight[m]: typeRoor: /NoneType' object is not callable
08:10 PM CaptHindsight[m]: TypeError
08:10 PM Bleep-CNC: Taht's my other one.
08:11 PM CaptHindsight[m]: and a bunch of other but I can't copy pasta
08:11 PM Bleep-CNC: Wow. and nothing exists for glade-gtk2 on the repo.
08:15 PM CaptHindsight[m]: there rare occasion that Debian has packages that are too new
08:24 PM CaptHindsight[m]: Bleep-CNC: https://en.wikipedia.org/wiki/GTK#Releases
08:28 PM CaptHindsight[m]: Bleep-CNC: looks like you have to port the GUI or use something a bit more modern
08:58 PM Bleepshop: Or re-install from the lcnc iso where the glade version works. :/
08:58 PM * Bleepshop has been reading the issues for gmoccapy on github.
09:01 PM solarwind: CaptHindsight[m] _most_ of their stepper motors
09:02 PM solarwind: CaptHindsight[m] https://www.omc-stepperonline.com/p-series-nema-23-closed-loop-stepper-motor-1-2nm-169-97oz-in-with-encoder-1000ppr-4000cpr-23e1k-12 like that one
09:02 PM solarwind: Some of them are even cheaper, around $40 CAD
09:04 PM CaptHindsight[m]: oh ok with the motor and under $40
09:05 PM solarwind: Yeah
09:05 PM solarwind: You can disassemble it from the motor easily, it's just 5 screws
09:05 PM solarwind: The encoder ring is coupled to the shaft with a set screw
09:13 PM CaptHindsight[m]: solarwind: that is what I's mount it on anyway
09:13 PM CaptHindsight[m]: interesting nema17 motors with encoders as well
09:14 PM CaptHindsight[m]: solarwind: have you come across any new nema17 closed loop motors with the drive attached to the rear of the motor?
09:15 PM solarwind: CaptHindsight[m] just these: https://www.aliexpress.com/item/1005003340856835.html
09:15 PM solarwind: CaptHindsight[m] and https://www.ustepper.com/
09:15 PM solarwind: second one uses a TMC5130 which has some level of motion control
09:16 PM solarwind: TMC has a very good chip for closed loop control https://www.trinamic.com/fileadmin/assets/Support/AppNotes/AN032_TMC4361A_closed_loop_motor_control.pdf
09:17 PM solarwind: the "stealthchop" is excellent, it really is silent
09:18 PM solarwind: If I were making a new compact closed loop driver, I'd go with the chips referenced in the app note above
09:22 PM CaptHindsight[m]: YATIDWTM
09:22 PM solarwind: say again?
09:22 PM _unreal_: again
09:22 PM CaptHindsight[m]: yet another thing I don't want to make
09:23 PM solarwind: then the ustepper is what I'd use
09:23 PM solarwind: just because it uses the TMC5130
09:23 PM CaptHindsight[m]: I'd like to buy a nema17 stepper with an integrated closed loop driver
09:23 PM solarwind: you can get the MKR servo42C PCB assembly on their own on aliexpress for about $20 CAD and mount them on to any NEMA 17
09:24 PM solarwind: Yeah then the above two links are what you want
09:24 PM solarwind: that's exactly what they are
09:24 PM CaptHindsight[m]: but i don't want to assemble it
09:24 PM solarwind: the first two links require no assembly
09:24 PM solarwind: They're ready to use
09:24 PM solarwind: Oh my bad, wrong first link
09:24 PM CaptHindsight[m]: I want one stop warranty complaints
09:25 PM CaptHindsight[m]: yeah
09:26 PM solarwind: https://www.aliexpress.com/i/1005004509772371.html if you search "servo42a" / "servo42b" / "servo42c", you'll find what you're looking for
09:26 PM solarwind: or the ustepper
09:27 PM solarwind: Click the first option from the link above for the assembled version
09:28 PM solarwind: Why avoid assembly though? it only takes a minute
09:29 PM solarwind: I guess if you build machines for customers, makes sense for easy warranty and what not
09:30 PM CaptHindsight[m]: 500 just a minutes all add up
09:31 PM CaptHindsight[m]: and no US supplier that I can find yet
09:32 PM CaptHindsight[m]: I can't rely on Chinese suppliers to ship from China
09:32 PM CaptHindsight[m]: I stopped doing that about 10 years ago
09:33 PM solarwind: CaptHindsight[m] https://www.leadshine.com/products/closed-loop-stepper/integrated-closed-loop-stepper-motor/ics-series.html
09:33 PM solarwind: They have US distributors
09:34 PM solarwind: and a US HQ
09:35 PM solarwind: 14 bit incremental magnetic encoder, should be pretty good
09:36 PM solarwind: If you're really stuck, I'll build em for ya :P
09:37 PM roycroft: we need to make stuff here and stop buying it from our enemies
09:37 PM solarwind: you can just hop the border to Toronto, they don't care. I know because I forgot my passport a couple of years ago
09:38 PM CaptHindsight[m]: solarwind: USA --> Canada or Canada --> USA?
09:38 PM solarwind: Both directions
09:39 PM CaptHindsight[m]: that was probably USA --> Canada since you had the proper secret handshake
09:39 PM solarwind: they also let me into the USA
09:39 PM CaptHindsight[m]: pics or it didn't happen
09:39 PM solarwind: I forgot it at home and it's a 2 hour drive
09:40 PM CaptHindsight[m]: it's unheard of
09:40 PM CaptHindsight[m]: in recent years
09:40 PM solarwind: less than 4 years ago
09:40 PM CaptHindsight[m]: with no complementary strip search and beating?
09:41 PM solarwind: I had to go inside for 5 minutes, but that's it
09:41 PM XXCoder: inside the torture box?
09:41 PM MikeM[m]: I think I looked in here at at the wrong (or possibly right?) moment.
09:42 PM solarwind: I had my drivers licence, and we all know that's all they really need
09:42 PM CaptHindsight[m]: MikeM: just discussing USA --> Canada border crossings
09:42 PM MikeM[m]: Gotcha
09:42 PM solarwind: they have all the information on you they'll ever need at their fingertips
09:43 PM CaptHindsight[m]: yes, but illusion of security is pierced
09:44 PM roycroft: real id is coming this year
09:44 PM roycroft: again
09:44 PM roycroft: like it has every year for the past decade or so
09:44 PM roycroft: but it's really coming this time
09:45 PM roycroft: maybe
09:45 PM CaptHindsight[m]: solarwind: is I forgot still an acceptable reason to stay in Canada without a residency permit for >6 months
09:45 PM solarwind: I've never once heard of anyone getting deported
09:45 PM Bleepshop: roycroft: Just like Global warming wiping out Obama's place on Martha's vineyard? LOL
09:45 PM CaptHindsight[m]: the deadline would be extended until May 7, 2025
09:45 PM XXCoder: not sure how that is related
09:46 PM roycroft: when i renewed my driver's license last (about 6 years go) i was required to produce a copy of my birth certificate and proof of residency in order to get it renewed
09:46 PM roycroft: because real id was here then
09:46 PM roycroft: they renewed my license
09:46 PM roycroft: after producing all the documents
09:46 PM XXCoder: that reminds me, I need to renew mine
09:46 PM CaptHindsight[m]: my last renewal was over the phone
09:46 PM roycroft: but it was not a real id license, because they were nor ready to issue them
09:46 PM Bleepshop: XXCoder: I'd give the flood-out higher odds than them getting their shit together on real-id.
09:47 PM roycroft: now they're telling me i can renew early, and get a real id license
09:47 PM roycroft: as long as i produce all the documents
09:47 PM roycroft: and i can do that any time, so they tell me
09:47 PM roycroft: except they still don't issue real id licenses
09:48 PM roycroft: and i'm not going to be able to get on a bus or a plane, or cross the border on the 49th, until i get a real id
09:48 PM roycroft: except i can still do all that stuff, because real id is not here yet, even though is is but it isn't
09:49 PM Bleepshop: I was so sure they'd fail to have it together last year I went for the 8 year renewal on my license.
09:49 PM CaptHindsight[m]: solarwind: I just need a place to live and job in Canada and I'm there
09:49 PM CaptHindsight[m]: which line do I stand in?
09:49 PM roycroft: 8 years is the only option for folks like me
09:49 PM roycroft: it's only young people who get 4 year licenses here
09:49 PM solarwind: I don't even know. I don't think there's a line
09:50 PM XXCoder: didnt know 8 years existed
09:50 PM roycroft: canada is pretty strict about immigration, unless you're from a commonwealth country
09:50 PM roycroft: most countries are, actually
09:50 PM CaptHindsight[m]: solarwind: do I have to request to own a farm or anything?
09:50 PM solarwind: A friend of mine from the US applied to nursing school here and got accepted and now he's here
09:50 PM roycroft: having a big wad o' cash helps
09:50 PM solarwind: I never heard him mention or ask anything about immigration stuff, so I assume it wasn't an issue
09:51 PM roycroft: if you're rich you can move almost anywhere
09:51 PM roycroft: but you can figure it out, capthindsight
09:51 PM roycroft: canada has a point system
09:51 PM CaptHindsight[m]: Canada has blocked the purchase of new homes for two years for foreigners
09:51 PM roycroft: and they publish the criteria
09:52 PM roycroft: you can add up how many points you have and you'll know if they'll let you in or not
09:52 PM CaptHindsight[m]: I've been studying Canadian for a few years
09:52 PM solarwind: CaptHindsight[m] I think that's for different reasons
09:52 PM CaptHindsight[m]: it gets harder as you get older
09:52 PM roycroft: that legislation is for foreign investors
09:53 PM roycroft: immigrants and people with permanent residence status can still buy homes
09:53 PM solarwind: it's because they were buying up all the properties in Vancouver
09:53 PM roycroft: they're just tired of chinese businss people buying up properties in the lower mainland bc and driving property values up to the point that locals cannot afford a home
09:53 PM CaptHindsight[m]: isn't Toronto also in a bubble?
09:53 PM solarwind: In the middle of the city, yeah
09:54 PM solarwind: but who the hell wants to live there anyway
09:54 PM CaptHindsight[m]: https://www.canadianrealestatemagazine.ca/news/whats-happening-with-toronto-real-estate-in-2022-335245.aspx
09:54 PM roycroft: the problem in bc started when hong kong was returned to the prc
09:54 PM roycroft: there was a mass exodus from hong kong to british columbia
09:54 PM Bleepshop: CaptHindsight[m]: Studying Canadian? Watched "Strange Brew" again?
09:55 PM * Bleepshop knows that if he hears "Take off hoser" he's right...
09:55 PM CaptHindsight[m]: solarwind: i had an office on Yonge st in Davisville
09:55 PM roycroft: he's learning how to pronounce "sorry" like "sawrey", and using it as often as usians use colorful metaphors
09:56 PM CaptHindsight[m]: CaptHindsight: is that area expensive or not worth living in now?
09:57 PM XXCoder: apparently ASL is main signed langiage, so are LSQ
09:57 PM CaptHindsight[m]: Bleepshop: pretty sure they don't talk like that anymore unless you live in the sticks
09:58 PM solarwind: CaptHindsight[m] yeah it wasn't that bad back in the day
09:58 PM solarwind: it's just overcrowded like any city now
09:58 PM CaptHindsight[m]: solarwind: how far north do you have to go be left alone?
09:58 PM Bleepshop: That's why I moved to an area with a population <50k.
09:59 PM solarwind: Not very far, like an hour drive or less
09:59 PM solarwind: it drops off very fast
09:59 PM solarwind: 2 hours and you're into the Ontario wilderness
10:00 PM Bleepshop: CaptHindsight[m]: You can do that <50 miles from me. and get 440V/3PH power and fiber internet. LOL
10:01 PM Bleepshop: Hell, I'm looking at 10k sq/ft of shop with a 1 bedroom apartment for $600/mo over there.
10:01 PM CaptHindsight[m]: I moved 50 miles out of Chicago 12 years ago, I think i have had enough of "country living" for a while
10:01 PM CaptHindsight[m]: it wasn't so bad when i was also out of the country half the time
10:02 PM CaptHindsight[m]: Bleepshop: sure but there is no culture
10:03 PM CaptHindsight[m]: Bleepshop: you have to have your foods and spices flown in
10:03 PM roycroft: it used to be that 90% of the population of canada lived within 100 miles of the us border
10:03 PM Bleepshop: CaptHindsight[m]: Las Vegas NM. 87701. Big enough for a Mall-Wart and a Starbucks but too small for Krispy Kreme or adult bookstores.
10:03 PM roycroft: if that is not still the case, i'm sure it's close to 90%
10:03 PM solarwind: That's still the case
10:04 PM roycroft: and i don't think it's because canadians love their neighbors in the us so much
10:04 PM roycroft: i think it's because the southern border of canada is way north to begin with
10:04 PM solarwind: no, it's just because of the great lakes and climate
10:04 PM ZincBoy[CAON][m]: The matrix to discord bridge seems to be generating "You're invited to talk on Matrix" messages after every user message. It is quite annoying.
10:04 PM roycroft: and everyone huddles around the border to keep warm
10:05 PM Bleepshop: roycroft: I think it has something to do with the fact that the further North you go the higher the odds of a bear kicking down your door and shitting on your rug. LOL
10:05 PM CaptHindsight[m]: XXCoder: any ideas on the bridge or is that all turboss?
10:05 PM XXCoder: capt its been working fine for a bit now
10:06 PM * ZincBoy[CAON][m] uploaded an image: (53KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/pJaMxKbUJqjevoySXJcCAJqA/image.png >
10:06 PM TurBoss: there still 2 bugs... the apos one and the mentions invite thing
10:06 PM TurBoss: that
10:06 PM XXCoder: yeah apos is extremely hard bug to fix
10:07 PM XXCoder: quote thing was fixed, turboss would need to remember how he did it last time
10:07 PM CaptainHindsight: oh yeah
10:07 PM CaptainHindsight: I see them
10:08 PM CaptainHindsight: 😫
10:08 PM CaptHindsight[m]: ZincBoy[CA, ON]: well hav you thought about joining? :)
10:09 PM ZincBoy[CAON][m]: LOL. I am trying to cut down. Teams, Slack, and Discord are enough.
10:10 PM CaptHindsight[m]: https://www.nbcnews.com/nightly-news/video/canadian-government-makes-immigration-push-to-fill-labor-shortage-159118405834
10:11 PM roycroft: it just occured to me that i don't need a particular thread pitch for my microadjuster
10:11 PM roycroft: i can use a common thread pitch, and adjust the angle that the adjuster feeds at to get the advance rate that i want
10:12 PM CaptHindsight[m]: wonder if they need more speedbump installers?
10:14 PM CaptHindsight[m]: Toronto: JOB OFFER: Urban Farmer for the 2023 season
10:14 PM solarwind: I just sprayed a whole bunch of motorcycle chain oil into my old paper shredder
10:14 PM solarwind: and then turned it on
10:14 PM CaptHindsight[m]: Jobs in Toronto for foreigners
10:14 PM solarwind: Forgot that the aerosol sprays have some volatile hydrocarbons in them lol
10:15 PM CaptHindsight[m]: no explosion so call it a win
10:15 PM solarwind: it exploded
10:15 PM solarwind: but no damage
10:15 PM solarwind: the volatile gas mixture settled into the enclosed bin and the motor spark ignited it
10:16 PM solarwind: so that was fun
10:17 PM Bleepshop: CaptainHindsight: Found it. Need to recompile glade to get version >3.8 without deprecated widgets.
10:17 PM CaptHindsight[m]: Bleepshop: yeah I knew it was some software thing
10:18 PM CaptHindsight[m]: glad to help
10:18 PM CaptHindsight[m]: solarwind: shreds and incinerates
10:18 PM Bleepshop: I actually tried running gmoccapy and then touchy direct from glade and got an error with touchy.
10:19 PM solarwind: I use it to make pet bedding. Just order catalogs for free.
10:19 PM solarwind: It popped the bin out, but other than that, the explosion had surprisingly little energy it seems
10:20 PM Bleepshop: solarwind: No seals to build pressure.
10:20 PM solarwind: yeah that's true
10:21 PM CaptHindsight[m]: solarwind: do they still make you wait 6 months to see a doctor up there?
10:21 PM solarwind: I've never had that issue
10:21 PM solarwind: If I break a bone, I get treated the same day
10:21 PM solarwind: if I want to see the GP for non emergencies, I can have the appointment in a couple of days
10:22 PM CaptHindsight[m]: i read that one in six Canadian docs are close to retirement
10:22 PM _unreal_: just scared the shit out of my daughter
10:22 PM solarwind: Only thing I can think of is specialist referrals for certain things
10:22 PM _unreal_: she was brushing her teeth and didnt bother to turn on the bathroom light.
10:23 PM _unreal_: I did a side ways door peek around were you litteraly lean over side ways and poke your head in lateral.
10:23 PM _unreal_: eheheheheh
10:23 PM solarwind: And I've never known anyone to have that issue either
10:23 PM _unreal_: I have hick ups now
10:23 PM CaptHindsight[m]: this is a public channel so child abuse will be reported
10:23 PM _unreal_: lol she just said I mock her with my hickups and must be bragging LOL
10:24 PM CaptHindsight[m]: solarwind: we have lots of lies down here about how bad the heath system is up there
10:24 PM Bleepshop: _unreal_: Axe wielding wombats.
10:24 PM solarwind: well obviously, there's a whole bunch of business assholes profiting off of being the middle men
10:24 PM _unreal_: I dont know what hurts worse, laughing or hickups
10:24 PM Bleepshop: _unreal_: Are the hiccups gone?
10:24 PM _unreal_: no
10:25 PM CaptHindsight[m]: solarwind: death panels, months to see docs, Canadians coming down to Florida for surgeries etc etc
10:25 PM Bleepshop: _unreal_: OK. So that tactic doesn't work on you.
10:25 PM solarwind: I've honestly witnessed zero cases of anyone having to go elsewhere for surgeries
10:25 PM solarwind: I've had a few myself and they've been _the same day_ of the accident
10:26 PM solarwind: and they could have safely waited a few days if needed
10:26 PM CaptHindsight[m]: solarwind: well if you want it done right stories
10:26 PM Bleepshop: _unreal_: Got a ffreind, she gets the hiccups and the easiest way to cure them is throw some cognitive dissoance at her. LOL
10:26 PM solarwind: I'm happy with my surgeons. Everything still works the way I expect it
10:26 PM CaptHindsight[m]: happy to hear
10:27 PM solarwind: The nurses on the other hand, I have a long story about that...
10:27 PM solarwind: absolutely evil
10:27 PM Bleepshop: solarwind: Yes, but can you play the piano? LOL
10:27 PM solarwind: Bleepshop yes I can
10:29 PM Bleepshop: solarwind: Yes, but could you play the piano before? [old joke LMAO
10:30 PM CaptHindsight[m]: every doc I tried that on knew that joke
10:30 PM solarwind: I don't get the joke. But yes I was able to play the piano just as well before
10:31 PM CaptHindsight[m]: solarwind: ah Patient asks the doc: will I be able to play the piano after surgery?
10:31 PM CaptHindsight[m]: Dos says : yes,...... Patient: well i always wanted to play the piano
10:32 PM solarwind: How did I know the punchline without even knowing the joke
10:33 PM CaptHindsight[m]: https://www.youtube.com/watch?v=Bg36PU96U0w the best ones
10:34 PM solarwind: Ah the sleeping pills joke, too true
10:37 PM CaptHindsight[m]: solarwind: are you building high-g cnc glue guns?
10:39 PM CaptHindsight[m]: about 8 years ago there was a company trying to print water soluble molds for injection molding
10:40 PM CaptHindsight[m]: or extruded thermoplastic shells that were injection molded or filled with casting thermosets
11:14 PM isaacggw[m]: How should I go about controlling my PM25 spindle with linuxcnc?

11:38 PM isaacggw[m]: It is just the standard controls that come with the precision Matthews p.m. 25 mill
11:38 PM xxcoder8265[m]: yeah looks like matrix to discord thats issue
11:38 PM isaacggw[m]: I was hoping to just add that and not use a VFD
11:38 PM xxcoder8265[m]: its still working so eh
11:38 PM CaptHindsight[m]: So only from matrix
