12:04 AM jesseg: CaptainHindsight, you around? Here's them funny bearings I was talking about: https://i.ibb.co/c1yH776/20220821-211640.jpg
12:13 AM XXCoder: interesting allright
12:39 AM roycroft: yeah, this was always a fun star trek
12:39 AM roycroft: landru just blowed up real good
01:19 AM TurBoss: morning
01:19 AM XXCoder: yo
01:19 AM TurBoss: hello XXCoder
01:20 AM TurBoss: found a issue in latest master `AttributeError: 'linuxcnc.stat' object has no attribute 'axes'`
01:20 AM TurBoss: using qtpyvcp
01:20 AM TurBoss: can't figure, doc says axes is there
01:20 AM TurBoss: https://www.linuxcnc.org/docs/devel/html/config/python-interface.html#_linuxcnc_stat_attributes
01:29 AM CaptHindsight[m]: jesseg: am now for a bit
01:30 AM CaptHindsight[m]: post on reddit
01:30 AM CaptHindsight[m]: see what comes up from ideas of the past
01:30 AM XXCoder: I guess low rpm too
01:31 AM XXCoder: otherwise springs would cause issue
01:32 AM jesseg: CaptainHindsight, what sub should I post in? I did just post it in r/machinist although it's unlikely anyone there will know, since I think it's something specific to aircraft instruments
01:35 AM CaptHindsight[m]: r/MechanicalEngineering
01:38 AM jesseg: Thanks!
01:49 AM jesseg: LOL, I just had a thought. It is remotely conceivable that my old late friend took a normal bearing and took out the cage and bought a bunch of springs and made these up LOL... Just dawned on me. He was not above trying new things to solve obscure problems.
02:00 AM CaptHindsight[m]: jesseg: sure
02:30 AM Deejay: moin
04:34 AM Tom_L: morning
04:55 AM JT-Cave: morning
07:07 AM cpresser1: jesseg: if it was a 'real' product I would assume that there is a cage in the bearings. Just one that has spots for less rollers/balls.
07:33 AM randy: cpresser1: ~~ ;)
08:07 AM perry_j1987: mornin
09:01 AM perry_j1987: whats everyone up to this morning
09:09 AM * roycroft is finishing some elections work and then will start packing for his camping trip
09:09 AM perry_j1987: where you going camping
09:10 AM roycroft: on the northern oregon coast
09:14 AM perry_j1987: nice area
09:14 AM perry_j1987: use to go to seaside every year
12:46 PM -!- #linuxcnc mode set to +v by ChanServ
01:07 PM perry_j1987: hows it going
02:22 PM perry_j1987: well i got the techno isel cross slide all apart
02:23 PM perry_j1987: going to machine this alum bracket they made for their cnc conversion so the cross sldie can travel further
02:23 PM perry_j1987: that coupled with getting rid of one of the limit switches will give me a ton more travel to get 6 or so tools on a gang tooling setup on here
02:24 PM perry_j1987: gotta drill two holes for relief and mill out a notch
02:24 PM perry_j1987: wish me luck
02:36 PM * JT-Shop is fixing to make a couple of tiny gripper arms for a tiny gripper....
02:38 PM JT-Shop: the screws that hold them on are #3-56
02:46 PM perry_j1987: what are you gripping
02:47 PM JT-Shop: a push on washer
02:48 PM JT-Shop: https://m.media-amazon.com/images/I/51ov7GkxJvL.jpg
02:49 PM JT-Shop: I have to grip the washer from the inside and place it in a part
02:55 PM -!- #linuxcnc mode set to +v by ChanServ
03:10 PM perry_j1987: doing enough of them to automate it eh?
03:10 PM perry_j1987: what are you making
03:12 PM JT-Shop: assembling the handle for a whirlpool mixer
03:14 PM CaptHindsight[m]: parts are too small even for tiny Chinese children's hands
03:15 PM t4nk_fn: jesseg, what's with the coloration of those things? is it just oil or is it the material?
03:20 PM CaptHindsight[m]: https://www.reddit.com/r/MechanicalEngineering/comments/wumc2o/what_is_the_purpose_of_these_springcaged_ball/
03:21 PM JT-Shop: https://pyxis.nymag.com/v1/imgs/670/604/3b4fbd3ac3ee3f1c7fd420ae5662115d9a-kitchenaidstandmixer.2x.rsocial.w600.jpg
03:21 PM JT-Shop: the black handle on that mixer
03:21 PM JT-Shop: the one on the right
03:22 PM JT-Shop: they must make a lot of them the assembly machine is up to 70k now
03:23 PM CaptHindsight[m]: those mixers are super popular
03:23 PM CaptHindsight[m]: the parts are pretty easy to find and don't change much from 40+ years ago
03:30 PM t4nk_fn: well, there's a couple of replies already there.. but it doesn't really mention the yellowish color
04:32 PM perry_j1987: odd so just powered up this lathe and the 7i96 sounds like a high pitch noise coming from it
04:32 PM perry_j1987: the 5v power supply was outputting about .4 or .5 of a volt if i unplug the 7i96 it goes back up to steady 5v
04:33 PM skunkworks: something shorted on one of the outputs?
04:34 PM perry_j1987: ah i see a broken ground on an endstop
04:34 PM skunkworks: I would unplug all the field io and see...
04:34 PM skunkworks: or find the problem.. ;)
04:35 PM perry_j1987: ok unplugged the endstops on the 7i96 and now it boots up heh
04:36 PM perry_j1987: that had me scared for moment hah
04:39 PM CloudEvil: :)
04:40 PM roguish[m]: what the heck is an endstop? this particular one.
04:41 PM CloudEvil: Sounds more like a beginningstop
04:41 PM perry_j1987: limit switch / end stop
04:42 PM -!- #linuxcnc mode set to +v by ChanServ
04:49 PM perry_j1987: hmm this is odd
04:49 PM perry_j1987: why is my soldering iron sparking to the wires
04:50 PM Tom_L: shitty iron?
04:51 PM perry_j1987: tenma station
04:52 PM perry_j1987: good brand
04:53 PM Tom_L: put a meter between the tip and the wire you're soldering
04:53 PM Tom_L: see what you get
04:53 PM Tom_L: poor grounding?
04:55 PM perry_j1987: its psosible
04:58 PM perry_j1987: 70v ac
04:59 PM perry_j1987: from the little endstop wire to the tip of the soldering iron wth! lol
05:02 PM perry_j1987: i unplugged the lathe and somehow there's 50v ac reading
05:13 PM perry_j1987: i did a bonehead mistake lol
05:13 PM perry_j1987: pinched the wires in the servo mount too haha
05:13 PM perry_j1987: thats what caused the problem
05:16 PM CaptHindsight[m]: the majority of the used machines i come across have wiring issues
05:17 PM Tom_L: probably why they're for sale
05:18 PM perry_j1987: this wasnt an issue till i made it one haha
05:18 PM perry_j1987: i just took the whole thing apart and milled the bracket so there was room for the cross slide to slide through it for the servo mount
05:18 PM perry_j1987: gave myself an extra 2-3 inches of travel now
05:18 PM JT-Shop: I pinched the hood latch cable in my truck once when changing the battery... took a while to find that
05:19 PM perry_j1987: then on reassembly i pinched all the endstop wires they came out of their groove and got pinched on the underside out of sight when assembling
05:19 PM Tom_L: hmm, it found 2.9.0 this time
05:19 PM JT-Shop: really, no pre?
05:19 PM Tom_L: well yeah
05:19 PM Tom_L: but it hasn't been finding it
05:19 PM * JT-Shop goes to do some bush hogging
05:40 PM perry_j1987: considering doing away with limit switches on this lathe
05:47 PM perry_j1987: so yesterday when i was trying to measure these threads to figure out what they were
05:47 PM perry_j1987: i didnt know that imperial threads apparently are measured from the root
05:47 PM perry_j1987: i was measuring the crest/peeks and thats why it didnt make sense
05:47 PM perry_j1987: so its deff a 1-1/2 x8 thread heh
05:51 PM CloudEvil: :)
05:54 PM JT-Shop: crest or root the pitch will be the same... they are 60°
05:54 PM perry_j1987: yet another reason imperial measurements should be thrown out lol
05:55 PM JT-Shop: don't hold your breath waiting for that
05:55 PM perry_j1987: we ALMOST did it... if that one ship wasnt sank in the 1700's with the weights lol
05:55 PM JT-Shop: lol
05:56 PM JT-Shop: imperials must have sunk it
05:56 PM perry_j1987: prob hah
05:56 PM Tom_L: jt to get 12 or 13 you have to upgrade from 11?
05:56 PM JT-Shop: yep, there is no live build for testing or unstable
05:56 PM perry_j1987: in any case im going to order a Bostar 5c collet chuck for this lathe
05:56 PM JT-Shop: and 13 will report back 12 until it's in testing
05:57 PM Tom_L: i may set up another test pc
05:57 PM JT-Shop: I have a 5c collet chuck that I hold with the 4 jaw chuck
05:57 PM perry_j1987: one of those cartridge types?
05:57 PM JT-Shop: I'm doing 13 again to see what I missed
05:57 PM perry_j1987: i seen one of those before
05:57 PM Tom_L: 3rd time today building this
05:58 PM Tom_L: still comes up short one way or another
05:58 PM JT-Shop: not sure what it's called
05:58 PM Tom_L: trixie
05:58 PM Tom_L: ?
05:58 PM perry_j1987: lol
05:58 PM Tom_L: pixie?
05:58 PM JT-Shop: the 5c chuck...
05:58 PM Tom_L: probably one of those euro metric things
06:00 PM JT-Shop: https://www.travers.com/media/catalog/product/6/3/63-302-170_08-22-00.jpg
06:00 PM JT-Shop: perry_j1987, like that one
06:01 PM perry_j1987: yup thats pretty much what im getting
06:01 PM perry_j1987: i'd LIKE a pneumatic one but its not in the budget
06:01 PM perry_j1987: im told its like 40 turns of the chuck key for these to open and close though
06:01 PM JT-Shop: I only keep a 4 jaw chuck on the Samson lathe
06:01 PM perry_j1987: seen alot of guys using a imapct driver for them
06:02 PM JT-Shop: mine is not that bad
06:02 PM JT-Shop: I think mine is a cheaper version of the bison
06:04 PM perry_j1987: its not a bad deal 140bucks with the backplate semifinished
06:04 PM Tom_L: 11% done to failure
06:05 PM perry_j1987: i also have to drill out a hole in the electrical cabinet of this techno isel
06:05 PM perry_j1987: i'll 3d print some sort of conduit through the electrical cabinet so i can pass bar stock through
06:05 PM perry_j1987: then with the 5c and that conduit done this lathe will be some semblance of a useful little lathe
06:05 PM perry_j1987: in addition to this modifications im making today to increase the travel for gang tooling
06:05 PM JT-Shop: what are you building Tom_L
06:05 PM Tom_L: this one is arm64 live build
06:05 PM JT-Shop: cool
06:05 PM Tom_L: 2.9.0 pre
06:05 PM Tom_L: is the hope
06:05 PM CaptHindsight[m]: it's a good thing it is Debian or building ISO's would be complicated :)
06:05 PM perry_j1987: then i'll make a subplate to perm bolt onto the t slot with locating pins and all the gang tool blocks i make will bolt to that. i'll use the lathe itself with my boring head to make the lathe tool blocks inline with the spindle
06:06 PM Tom_L: run into a few problems trying the 32bit version armhf
06:06 PM Tom_L: for bookworm
06:07 PM perry_j1987: the idea is to have diff tool blocks for diff jobs ready to go and i can just plop them on and go
06:07 PM JT-Shop: take a photo when you have it setup
06:07 PM * JT-Shop calls it a day
06:08 PM perry_j1987: aye
06:26 PM skunkworks: lol - I posted this earlier..
06:26 PM skunkworks: lol - hacking a running config.. Make sure paralel port reset isn't true for a pin you want to output pwm...
06:26 PM skunkworks: it makes no sense what is going on for a bit..
06:38 PM Tom_L: yay
06:39 PM -!- #linuxcnc mode set to +v by ChanServ
06:39 PM Tom_shop: P: Build completed successfully
06:40 PM perry_j1987: any reason i should keep these limit switches on this lathe??
06:40 PM Tom_L: you'll find that reason as soon as you remove them
06:41 PM perry_j1987: always touching off the work every time anyways
06:42 PM perry_j1987: the ones that are on this lathe are those little lever arm microswitches
06:52 PM XXCoder: CaptHindsight[m]: theres guy in reprap asking about laternate computer boards if you care to go over there
07:08 PM unterhaus_: what's a laternate computer board/
07:09 PM CloudEvil: It's one that can't type.
07:17 PM XXCoder: yup
07:17 PM perry_j1987: ok i got 147mm of travel on X now
07:18 PM perry_j1987: i could eek out a tinybit more say 25 more mm if i do a bit more machining
07:19 PM perry_j1987: and thats with about 60% of the saddle supported on either extreme
07:19 PM perry_j1987: err cross slide
08:02 PM -!- #linuxcnc mode set to +v by ChanServ
08:18 PM pcw-home: Got a free pair of wire cutters
08:19 PM Tom_L: yay
08:19 PM Tom_L: will they cut wire?
08:19 PM pcw-home: Left by a copper thief
08:19 PM Tom_L: even better...
08:19 PM Tom_L: hah
08:20 PM Tom_L: cost you a pile of copper?
08:20 PM pcw-home: They opened the wire entry box to our business but thats as far as they got
08:21 PM pcw-home: 440 400A no way to turn off except by PGE
08:22 PM pcw-home: lucky they are not dead (we will add a lock the box just had a sliding cover)
08:22 PM Tom_L: or some stupid method :)
08:22 PM pcw-home: yeah short out and blow the fuse I guess
08:23 PM TurBoss: phew
08:23 PM pcw-home: the wire cutter would not have even worked (way too small)
08:23 PM Tom_L: well i did get an arm64 iso now to get it in the right format
08:24 PM Tom_L: chain cutters
08:25 PM pcw-home: yeah something big. No great love of thieves but I'd prefer not to find one dead
08:25 PM Tom_L: will rpi read ntfs?
08:26 PM pcw-home: I guess Linux has ntfs support
08:26 PM Tom_L: i'm running a build with that switch to see
09:26 PM CaptHindsight[m]: XXCoder: just got back
09:27 PM CaptHindsight[m]: XXCoder: https://forum.linuxcnc.org/18-computer/46077-potential-all-in-one-single-board-computers
09:28 PM CaptHindsight[m]: the focus is mainly on boards with ARM SOC's that have integrated microcontrollers for step gens like the BBB, but it also includes boards that can connect to Mesa FPGA's via SPI, Ethernet or PCIe
09:29 PM XXCoder: capt thanks
09:30 PM CaptHindsight[m]: XXCoder: where is #reprap on Libera?
09:30 PM XXCoder: yeah on libera
09:34 PM Tom_L: CaptHindsight[m], any experience formatting an iso to rpi img?
09:34 PM CaptHindsight[m]: Tom_L: I forget what the Rpi needs
09:35 PM CaptHindsight[m]: fat32 or similar?
09:35 PM Tom_L: i'm hoping the first iso had the wrong format... building one with ntfs now
09:35 PM Tom_L: if ntfs doesn't work i'll try fat32
09:35 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/live-build/raspberrry_pi_amd64.jpg
09:35 PM Tom_L: first try
09:35 PM Tom_L: i did get an iso built
09:36 PM -!- #linuxcnc mode set to +v by ChanServ
09:36 PM CaptHindsight[m]: the Rpi4 is on the bench but not connected to anyting
09:36 PM Tom_dev: https://man.cx/lb_config(1)
09:37 PM Tom_dev: trying --binary-filesystem ntfs now
09:37 PM CaptHindsight[m]: "The SD card formats supported by the Raspberry Pi bootloader are FAT16 and FAT32 only."
09:37 PM Tom_dev: may as well bail on this then
09:37 PM Tom_dev: and do fat32
10:02 PM CaptHindsight[m]: looking for the closed loop stepper configs for LPT ports
10:04 PM CaptHindsight[m]: https://github.com/LinuxCNC/linuxcnc/blob/master/configs/by_interface/parport/etch-servo/etch.hal
10:06 PM CaptHindsight[m]: I thought that there was an example for closed loop Step Dir using LPT
10:07 PM CaptHindsight[m]: using incremental encoders
10:09 PM Tom_L: https://forum.linuxcnc.org/38-general-linuxcnc-questions/3916-closed-loop-with-steppers
10:09 PM Tom_L: dunno
10:14 PM CaptHindsight[m]: the forums and ML are flooded with variations
10:15 PM CaptHindsight[m]: servo stepper configs, closed lop stepper, PID stepper, PID step dir, closed loop step dir, servo step dir ahhhhhhhh
11:26 PM Tom_L: fat32 didn't work. need to figure out how to convert iso to img
11:27 PM Tom_L: but i think fat32 is still needed
11:27 PM XXCoder: maybe im dumb but isnt iso actual image format?
11:27 PM Tom_L: rpi won't recognize it
11:27 PM Tom_L: the pc will
11:27 PM XXCoder: I just dd directly from iso to sdcard
11:27 PM XXCoder: or use etcher
11:28 PM Tom_L: yeah so did i
11:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/live-build/raspberrry_pi_amd64.jpg
11:29 PM Tom_L: still getting similar messages
11:29 PM XXCoder: interesting
11:29 PM XXCoder: cearly expects partition to be fat
11:29 PM Tom_L: you figure it out and lemme know in the AM
11:30 PM XXCoder: how did you build the image?
11:31 PM Tom_L: live build
11:31 PM Tom_L: from scratch
11:32 PM Tom_L: cross compiled to arm64
11:33 PM Tom_L: some boot thing is missing or something
11:38 PM XXCoder: from what I see your partition arent fat
11:38 PM XXCoder: get sdcard out and check it on pc, see what partion is
11:38 PM XXCoder: see if its ex4, or fat or whatever
