12:02 AM XXCoder: maybe but then seems everyone makes samples of filiment test to dial in
12:22 AM XXCoder: i think the picture isnt great one for engraving heh
12:22 AM XXCoder: gonna test another pic once its done
12:30 AM XXCoder: i need a firm bed for my laser machine lol
12:31 AM XXCoder: its on box atm and its not a steady platform, nor flat
12:32 AM CaptHindsight: 5 ton block of concrete might just do it
12:33 AM XXCoder: lol
12:33 AM CaptHindsight: unless you're on floor 3 of a frame building
12:33 AM CaptHindsight: then it's a pendulum
12:33 AM XXCoder: then its 10 tons
12:34 AM CaptHindsight: people do forget about machine bases
12:38 AM CaptHindsight: https://www.youtube.com/watch?v=8PSG2al1Sus
12:38 AM CaptHindsight: a true classic
12:48 AM XXCoder: made a R engrave
12:48 AM XXCoder: its mirrored
12:59 AM XXCoder: really simple fix tho, swap y and yr
02:03 AM Jymmm: Tom_L: I rather have a bottle in front of me, than a frontalabotomy
02:17 AM XXCoder: didnt like swapped y and yr, reversed that and reversed x.
02:17 AM XXCoder: looks great
04:10 AM Loetmichel: XXCoder: could you try again?
04:10 AM XXCoder: on what?
04:10 AM Loetmichel: i am testing from home: works. testing from company: doesent
04:10 AM XXCoder: oh site
04:11 AM Loetmichel: the links to my website
04:11 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=10791
04:11 AM XXCoder: it scrolled up. thanks
04:11 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=10788
04:11 AM XXCoder: Firefox can’t establish a connection to the server at www.cyrom.org.
04:12 AM Loetmichel: strange
04:12 AM XXCoder: yeah
04:12 AM Loetmichel: maaan, what did they damage this time?
04:12 AM Loetmichel: i can access it just fine from home, from the company its the same as you
04:12 AM Loetmichel: ?!?
04:12 AM XXCoder: ip change?
04:14 AM Loetmichel: nope, botk copputers resolve the same IP for www.cyrom.org
04:14 AM Loetmichel: thats fishy
04:15 AM XXCoder: starts with 80. and ends with .125?
04:15 AM Loetmichel: yes
04:15 AM XXCoder: icmp_seq=5 Destination Net Unreachable
04:21 AM Tom_L: morning
04:22 AM XXCoder: yo
04:22 AM Tom_L: laser working better?
04:22 AM XXCoder: yep did lot of fixing and tuning
04:23 AM XXCoder: figuring what its abilities are
04:25 AM XXCoder: im taking some break then ill remove old laser board and put in new one into rame.
04:28 AM XXCoder: (its running machine but its off on box off the frame lol not very safe)
04:30 AM XXCoder: tom i do plan to test cutting for cardboard, but that needs more safe place to test it out on.
04:30 AM XXCoder: not on box on floor
04:35 AM Deejay: hi
05:13 AM jthornton: morning
05:13 AM XXCoder: wb
05:18 AM jthornton: cold front moving in we'll be in the teens Sunday night
05:21 AM XXCoder: here its all 40s
05:21 AM XXCoder: rain
05:31 AM jthornton: raining pretty hard at the moment
05:33 AM XXCoder: fun
05:34 AM XXCoder: my laser engraver is partially disassembled. build showed it liiping wire though gantry
05:34 AM XXCoder: its bad idea and wastes wire length
05:34 AM jthornton: got a photo?
05:34 AM XXCoder: so im removing that and im thinking on how to use spring wires to hoist it upwards.
05:35 AM XXCoder: not yet
05:50 AM XXCoder: took few pics need a bit before upload
06:09 AM jthornton: 10:00 hours of daylight today
06:33 AM XXCoder: jthornton: https://imgur.com/a/s9u6x6B
06:33 AM XXCoder: Tom_L: _unreal_
06:40 AM gloops: cheap drag chain any good for that XXCoder?
06:41 AM XXCoder: wires isnt quite long enough im thinking using some spring wire
06:41 AM XXCoder: so wires stay up
06:43 AM gloops: should work ok yeah
06:44 AM gloops: i always think of looking for these things in household stuff that might be laying around, spring wire...tricky one
06:45 AM gloops: those flexible plastic duct pipes for tumble dryers, kitchen extractors etc, have springy wire
06:46 AM XXCoder: it dont really have to be spting wire, it can be just lower gauge wire
07:27 AM Tom_L: 32°F Lo 25
07:40 AM miss0r2: jthornton: Wanna see my blooper from last night? :D
07:41 AM jthornton: sure
07:41 AM miss0r2: https://imgur.com/a/4mi3Ect
07:41 AM miss0r2: notice the chamfer in the lower right corner on the bore
07:41 AM miss0r2: 3rd last operation :)
07:41 AM jthornton: opps
07:41 AM miss0r2: hehe yea
07:42 AM jthornton: that's a busy part, what does it do
07:42 AM XXCoder: can it be salvaged?
07:42 AM miss0r2: Its an improved oil pan for my land rovers transfer box
07:42 AM XXCoder: if its something like steel can weld then mill it again?
07:42 AM jthornton: more surface area?
07:42 AM miss0r2: XXCoder: Well... if I wouldn't mind using a huge washer for that bolt, sure.. but I mind :)
07:43 AM jthornton: you could counterbore and fit a cylinder
07:43 AM miss0r2: jthornton: That part is just for shits'n giggles :) It never overheats with me driving it.. But the original pan is a 1.5mm sheet folded double over the gasket area. Its simbly too flexible to get a proper seal
07:43 AM miss0r2: This is 10mm alu on the gasket area. Somewhat stiffer
07:43 AM jthornton: ah that makes more sense now
07:43 AM miss0r2: jthornton nah :)
07:44 AM miss0r2: scrap! :)
07:44 AM jthornton: but your like me if you can make it fancy do it
07:44 AM XXCoder: big washer lol enough to bend em in
07:45 AM miss0r2: jthornton: Now that I scrapped the first part, I'm considering making the lines "wavey"
07:45 AM miss0r2: as an added bonus :D
07:45 AM jthornton: nice
07:45 AM miss0r2: But I'm not sure I can be bothered to draw all that geometry
07:46 AM miss0r2: in addition, I will need to do something about the tool path.. or make a cleanup path on the bottom of the slots there. It reflects on the side of the protruding heat sinks and makes the surface look like crap :D
07:46 AM miss0r2: Not only on camera, also when you look at it in person
07:47 AM miss0r2: bah. family time. See you around
07:48 AM jthornton: k
07:57 AM jymmmm: good morning folks
07:58 AM XXCoder: yo
07:58 AM jymmmm: jthornton: Is the shop the only wood stove you have?
08:00 AM jymmmm: BTW... Is anyone interested in SIMTEL - MSDOS collection by chance? 9GB zipped
08:00 AM XXCoder: huh
08:00 AM jymmmm: XXCoder: If you don't know what SIMTEL is, no big deal.
08:00 AM XXCoder: lol
08:01 AM XXCoder: okay first rule of club is never talk about club
08:01 AM jymmmm: SIMTEL was a repository of freeware/shareware for MSDOS, WINDOWS, etc
08:01 AM XXCoder: found archive site
08:02 AM XXCoder: http://www.lanet.lv/simtel.net/msdos/index-msdos-pre.html
08:02 AM jymmmm: Yep, that's it
08:03 AM jymmmm: The archives are getting harder and harder to find these days
08:03 AM jthornton: again I have 3 wood stoves
08:03 AM XXCoder: files links is broken
08:03 AM XXCoder: wanted to read asm magazine
08:05 AM jymmmm: jthornton: HAve you ever come across burning oak and the damper mostly closed and it just smolder like crazy? Almost acting like there is a blockage?
08:05 AM jymmmm: jthornton: or even with the damper fully open but acting the same, like it's starving for air?
08:06 AM SpeedEvil: damp wood?
08:06 AM jthornton: yea sometimes the wind or something is just right and it creates a positive pressure on the flue
08:06 AM jthornton: makes it hard to get a fire going sometimes
08:07 AM jymmmm: SpeedEvil: maybe a bit damp, but 2year seasoned.
08:07 AM jymmmm: jthornton: We dont have a lot of wind up here, and this is after the stove has been going for 2+ hours
08:07 AM SpeedEvil: yeah - that should be fine unless you seasoned it in a pond
08:08 AM jthornton: sounds like langoliers
08:10 AM jymmmm: It was weird, been going for 6 hours, moslty smoldering, open the door to stire things up, set off the smoke alarm many times. Then just shut it down, 6 hours later at 4am set off the smoke alarm again WITHOUT opening the door
08:11 AM jymmmm: With soft wood, hadn't been an issue at all.
08:12 AM jymmmm: Just really weird, hadn't come across this before. I have to wait till the snow melts to get on the roof to inspect /sweep it
08:15 AM jymmmm: I just anted to know if anyone else came across something like this before
08:19 AM _unreal_: morning
08:24 AM Loetmichel: *maaaan* thats what you get if you let the coworker make a DP adapter cable... Lane 0, 2 and 3 + and - swapped, ground for the prom is missing, 3,3V pr the prom is shorted to gnd and also missing on the other end. *repairing the GPU* *repairing the cable* CANT THAT GUY DO RIGHT ONCE? [/pissed]
08:27 AM Loetmichel: ... so much for "just going to work on a saturday for a few hours, wife. Will be back soon!"
08:37 AM JT-Shop: jymmmm, I use an old hair dryer to get my embers rocking in the morning
08:40 AM jymmmm: JT-Shop: By morning, I don't have any embers, stove is cold by then.
08:42 AM jymmmm: XXCoder: ASMMAG1 https://pastebin.com/raw/WFt5DG3f
08:44 AM jymmmm: XXCoder: if you want the others, let me know ASAP
08:47 AM jymmmm: JT-Shop: ...but, I'm not loading up the stove before going to bed at night either.
08:49 AM _unreal_: shiver me embers
09:02 AM skunkworks: jymmmm: did you see the converstaion about proxmox?
09:02 AM skunkworks: I like it so far.
09:03 AM jymmmm: skunkworks: the fallover? I did =) How long did it take? instantly?
09:05 AM jymmmm: skunkworks: Also, how do you have the replication setup and how often?
09:11 AM jymmmm: JT-Shop: Still learning to NOT to overfire the stove, it's way too easy to get the house into the 80's without realizing it.
09:16 AM jymmmm: XXCoder: ping
09:21 AM skunkworks: jymmmm: the fall over took a minute or 2
09:22 AM skunkworks: this was replicating every 15 minutes - but that could be tweeked. it will depend on how much actually changes. On our slow testing network - it was taking about 6 seconds to replicate
09:23 AM skunkworks: but not much changing obviously.
09:23 AM skunkworks: (after the first full replicate which took minutes)
09:24 AM skunkworks: only a 32gb windows server 2019vm
09:30 AM skunkworks: Haven't really looked to see what it uses to figure out if it should fall over..
09:31 AM skunkworks: it was funny - I was goofing around with it and shut the vm down. After a bit - it was running again. WTF - then dawned on me - in HA - it keeps the vm running no matter what.
09:51 AM Tom_L: jymmmm, where's the zip file?
10:02 AM Tom_L: jymmmm, i think most of those links are dead
10:04 AM Tom_L: picked a few random ones and they were all dead
11:46 AM _unreal_: well I finally got some REAL word back on my fathers condition. Stage 4 cancer
11:47 AM Elmo40: >_<
11:47 AM Loetmichel: _unreal_: ouch.
11:47 AM _unreal_: and he's FIANLLY accepted that he FUCKED UP in ignoring doing a colonoscopy and the other SIGNS there was an issue.
11:48 AM _unreal_: he could have gotten checked out 2 years ago now when the first real signs started to show.
11:48 AM _unreal_: people have recovered from stage 4 before. happens often but thats about as much as I know.
11:52 AM unterhaus: sorry to hear that. My dad was lucky because he had pain from gallstones, but they found his colon cancer as a result of finding thatcancer
12:02 PM _unreal_: yep.. some peole get the two for one'er
12:35 PM * Deejay did his first colonoscopy three days ago (age 39)
12:36 PM Elmo40: i should...
12:36 PM Deejay: there is no reason for not doing this.
12:36 PM Elmo40: very true
12:37 PM Deejay: my dad died last november... cancer. he never did any prevental medical checkup
12:37 PM Deejay: of course it was too late when the cancer was detected
12:37 PM _unreal_: I should type on this keyboard not the cad computer keyboard
12:37 PM _unreal_: heeh
12:37 PM _unreal_: ya I turned 40 last year
12:37 PM _unreal_: my birthday is comming up 41 in march :/
12:37 PM Deejay: he was 2 weeks in hospital, then 2 weeks at home. then he died.
12:38 PM _unreal_: so he was late stage 4
12:38 PM Deejay: dunno about the stages
12:38 PM Deejay: the cancer already spread (if thats the right term)
12:38 PM _unreal_: yes
12:39 PM _unreal_: metastasize
12:39 PM Deejay: jep
12:39 PM _unreal_: and yes that would be late stage 4
12:39 PM Deejay: ah okay
12:39 PM _unreal_: I only found out a few hours ago stage4
12:40 PM Deejay: that really hard :( i feel with you
12:43 PM _unreal_: sad thing is I spent so many years as a nurse, medtech, and working for the jackson lab where I had to put down thousands of mice. I'm kind of numb to the sad emotion aspect.
12:43 PM _unreal_: well currently anyays
01:08 PM SpeedEvil: Checkups in general have very very mixed results and you need to carefully work through if doing them has a point. Very often, for many checkups, with a 'positive' there is significant harm done by interventions on things you would have died with, not from.
01:08 PM SpeedEvil: Never mind incidental findings.
01:10 PM SpeedEvil: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4322920/ is worth a read and a think.
01:45 PM CaptHindsight: is you cup half empty or full?
01:46 PM CaptHindsight: sounds better using you vs your
01:47 PM _unreal_: hum
01:47 PM _unreal_: well I'm milling an other one of these feet
01:47 PM _unreal_: err not feet
01:47 PM _unreal_: bearing retainers
01:47 PM CaptHindsight: foots?
02:07 PM _unreal_: they are end captures
02:07 PM Jymmm: Tom_L: Got a place for me to upload it to? 9GB
02:08 PM SpeedEvil: https://osmocom.org/projects/osmo-fl2k/wiki If your parallel port is not fast enough.
02:08 PM SpeedEvil: (150MHz ADC *3 from a $5 USB dongle.)
02:08 PM _unreal_: I'd have to snap a photo but regardless they are HDPE based rectangles with a hole in the middle to hold the outter ring of the bearings, and two screw holes with lots of slop for centering. they are mounted on the + / - sides of the aluminum holders for the lead screws
02:09 PM _unreal_: SpeedEvil, ?
02:09 PM SpeedEvil: _unreal_: random project that I thought people might be interested in - linuxcnc came to mind.
02:09 PM SpeedEvil: And DAC, not ADC, I can't type
02:10 PM SpeedEvil: 150Msteps/s
02:10 PM _unreal_: SpeedEvil, I thought lcnc does NOT support usb devices
02:11 PM SpeedEvil: It was not a serious suggestion.
02:17 PM Loetmichel: MAN what a pain... finally got the PC with the DP and the 3 HDMI converters running... just to notice that it freezes when i plug in the fourth monitor... THANKS Microsoft. With win7 that was no problem, win10 (as customer ordered) 2Monitors: works, 3 displays: staggers, 4 displays: frozen solid. If you unplug the fourth it is back to staggering though. seems not only my coworkers can do
02:17 PM Loetmichel: anything right, M$ cant either :-(
02:18 PM CaptHindsight: Loetmichel: possible feature vs bug
02:19 PM _unreal_: so I got my vacuum working for my cnc again FINALLY
02:19 PM _unreal_: my 12v car vacuum
02:19 PM CaptHindsight: SpeedEvil: nice, i recall something similar years ago, might have been the start of that project
02:20 PM _unreal_: I thought the motor went bad
02:20 PM _unreal_: come to find out the impeller slips and drops down till it starts to contact something it shouldnt
02:21 PM Loetmichel: CaptHindsight: feature? how so?
02:41 PM SpeedEvil is now known as Guest84965
02:43 PM BitEvil_ is now known as SpeedEvil
02:59 PM Tom_L: Jymmm, not easily
03:21 PM Jymmm: Tom_L: Here the file list 3MB... https://defuse.ca/b/lldpqxYueqqUiaW24BrwGr
03:23 PM Jymmm: Tom_L: It is NOT in alphabetical order
03:34 PM nvz: which mode should I put the parport in? EPP, ECP, ECP w/ DMA, PS/2 or AT?
03:35 PM burklefoo: EPP is often best for drive strength
03:59 PM Deejay: gn8
04:13 PM Rab: Started the holiday weekend off right: http://reboots.g-cipher.net/screwed.jpg
04:17 PM Jymmm: Rab: They go in your roof, not your hand
04:19 PM Jymmm: Rab: looks like your hand is/was pretty swollen too
04:22 PM Jymmm: Rab: BTW, replace the siren with a motor and tin can... Same effect, less shock the shit out of you at 4am
04:25 PM Rab: Jymmm, haha, eventually solved that problem by banning the cats from the house.
04:26 PM Jymmm: Rab: that works too =)
04:26 PM Jymmm: Rab: hows the hand doing?
04:26 PM Rab: Jymmm, doing OK, the doc numbed it up and literally unscrewed the screw.
04:27 PM Jymmm: Rab: Did it get JABBED in otr screwed it? About an inch???
04:29 PM Rab: The screws I had were too small to hold the conduit hangers I was using, and the washers I had were slightly too small for the screws, so I was holding a washer in a pair of vise grips and putting in the screw with a cordless drill. Of course the washer slipped.
04:29 PM Rab: I need to print out the pic to hang in my workshop and remind me of my stupidity.
04:30 PM Jymmm: Rab: You in the US?
04:30 PM Rab: Jymmm, affirmative.
04:30 PM Rab: It went in about 1/2". My hands aren't that big.
04:31 PM Jymmm: Rab: Send to walgreens.com they'll print an 8x10 for about $4. some stores are 24hr and one hour pickup
04:31 PM Jymmm: Rab: Then hit dollar tree and get a frame for $1
04:31 PM Rab: Jymmm, sounds like a plan.
04:32 PM Jymmm: I've done that before with some on the fly photographs I've taken of people and to give as gifts
04:41 PM Jymmm: Tom_L: You can use this to see the descriptions, I have the files of course http://www.lanet.lv/simtel.net/msdos/index-msdos.html
04:41 PM Tom_L: most of the links are broke though
04:42 PM Tom_L: sunsite.lanet.lv cannot be found.
04:42 PM Tom_L: i probably wouldn't use it anyway
04:43 PM Jymmm: Yes, all the archives are dead, just the indexes remain
04:43 PM Tom_L: what good is that?
04:43 PM Jymmm: The last one I had found was in japan, that' when I grabbed them
04:44 PM Jymmm: Cause it's a single html file
04:44 PM Tom_L: don't worry on my part...
04:44 PM Jymmm: Tom_L: ok =)
04:44 PM Jymmm: Was jsut offering
04:44 PM Tom_L: if you happen across the files i might grab em though
04:44 PM Tom_L: just for posterity
04:45 PM Jymmm: I HAVE the files
04:45 PM Tom_L: oh?
04:45 PM Jymmm: Tom_L: 2020-01-18.13:14:34 Jymmm: Tom_L: Here the file list 3MB... https://defuse.ca/b/lldpqxYueqqUiaW24BrwGr
04:52 PM Tom_L: 1 big zip file?
05:04 PM Jymmm: Tom_L: yeah, 9GB
05:08 PM XXCoder: Jymmm: lol patebin under heavy load
05:08 PM Jymmm: XXCoder: the link I gave a long time ago?
05:08 PM XXCoder: yeah
05:16 PM Jymmm: XXCoder: https://defuse.ca/b/Hz95ZV5Bifur69rjn7joCB
05:16 PM XXCoder: thanks
05:20 PM XXCoder: mailed checks lol old
05:20 PM XXCoder: if it was written today, "just paypal me or something"
05:21 PM Jymmm: XXCoder: Did you not see the FIDONET address?!?!?!
05:21 PM XXCoder: ?
05:22 PM Jymmm: XXCoder: FIDONET predates email
05:22 PM XXCoder: sunnyvale?
05:23 PM XXCoder: ah different protocol, something akin to email I guess?
05:23 PM Jymmm: BEFORE internet
05:23 PM Jymmm: dialup BBS email
05:25 PM Jymmm: XXCoder: https://en.wikipedia.org/wiki/FidoNet
05:25 PM XXCoder: nice
05:26 PM XXCoder: i started by aol then internet. didnt use bbs a lot
05:26 PM XXCoder: in most cases, couldnt afford phone fees
05:26 PM Jymmm: You wou;d login to a LOCAL bbs
05:31 PM XXCoder: looks like bbs is making a return
05:31 PM XXCoder: using telnet
05:32 PM XXCoder: or its secure version
05:32 PM Jymmm: Both, dialup and telnet/ssh
05:35 PM Jymmm: XXCoder: And can even have over radio too
05:35 PM XXCoder: not surpised lol (wifi is radar too ;) )
05:35 PM XXCoder: byt yeah i know what you meant
05:36 PM Jymmm: No no, NOT WIFI, I mean like the same radio like walkie talkies
05:36 PM XXCoder: like I said...
05:39 PM XXCoder: this. "but yeah i know what you meant" ;)
05:40 PM XXCoder: and the that I said wifi is radar ALSO
05:41 PM XXCoder: welcome back lol
05:44 PM CaptHindsight: https://youtu.be/mxxdq6y8z8M somebody has stolen lots of Stuarts pixels!
05:44 PM CaptHindsight: LinuxCNC 5 axis cinci at MPM
05:45 PM CaptHindsight: Apr 18, 2008
05:45 PM CaptHindsight: pixels are cheaper now in 2020
05:45 PM XXCoder: i find it interesting that it has no toolchanger wheel or whatever
05:46 PM XXCoder: definitely a machine you must pay attention on what youre doing
06:40 PM Elmo40: CaptHindsight, LoL. Pixels are cheaper now!
06:40 PM Elmo40: but that is a monster machine!!
06:40 PM Elmo40: i bet it is rock solid, too.
06:52 PM andypugh: How many pixels?
06:57 PM andypugh: This is TkLinuxCNC on a 5120x2880 monitor: https://forum.linuxcnc.org/media/kunena/attachments/723/Screenshot2019-04-29at02.04.30.png
06:57 PM infornography: 5 pixels
06:57 PM XXCoder: extremely readable
06:58 PM andypugh: I suspect TkLinuxCNC wasnt
06:58 PM andypugh: ‘-really designed with that monitor in mind.
07:08 PM XXCoder: .42 n.m to n.cm
07:08 PM XXCoder: $wa .42 n.m to n.cm
07:08 PM XXCoder: $wa .42 n/m to n/cm
07:08 PM XXCoder: bah whatever
07:09 PM infornography: 42
07:09 PM XXCoder: yeah thats what I thought but wanted to confirm lol
07:09 PM infornography: boop beep
07:10 PM infornography: I'm just guessing tho
07:11 PM infornography: We have a bot that does conversion?
07:11 PM infornography: $wa help
07:11 PM XXCoder: yep
07:11 PM XXCoder: no help tho
07:11 PM XXCoder: $wa 100 usd to eu
07:12 PM XXCoder: $wa 100 usd to yuan
07:12 PM infornography: :/
07:12 PM XXCoder: ummm
07:12 PM XXCoder: gthx is dead
07:12 PM XXCoder: someone beat on it too often
07:15 PM XXCoder: okay I see why now
07:15 PM XXCoder: wrong channel. dammit. lol
07:18 PM infornography: lol
07:19 PM XXCoder: i wish this channel had gthx
07:34 PM jymmmm: XXCoder: Nope, just has Dolby Surround Sound 5.1
07:35 PM XXCoder: lol
08:11 PM JesseG: hey is pycam still around or did they die out?
08:12 PM andypugh: As far as I know
08:12 PM JesseG: The release notes sort of petered out in late 2017
08:13 PM JesseG: and the windows download link is 404
08:13 PM JesseG: and the macports command they give to install it on macos can't find py25
08:13 PM JesseG: so it almost looks abandoned
08:14 PM andypugh: This version was last updated 7 days ago: https://github.com/SebKuzminsky/pycam
08:14 PM JesseG: cool thanks!
08:14 PM JesseG: so I guess the bigger question is how to get a compatible python onto macos (it's for a friend)
08:15 PM JesseG: maybe it's macports that's abandoned :P
08:15 PM andypugh: I don’t know. I should, I am on a Mac as we speak.
08:15 PM andypugh: But (to my chagrin) I rather tend to use Fusion360
08:17 PM andypugh: Are you on the LinuxCNC mailing list? You could ask Seb for clarification there.
08:17 PM JesseG: no I'm not
08:18 PM andypugh: I think he took it over, sort of, and brought it in to the LinuxCNC org, in some vague way, and then sort of faded out of both,,,
08:18 PM andypugh: I am unclear on the details :-)
08:19 PM andypugh: But, yes, some version of PyCAM is definitely still getting updates. But how that relates to releases, who knows?
08:19 PM JesseG: sounds good to me
08:20 PM JesseG: I'm just not a mac guy, and not a python guy either. Me and curly braces are good friends lol
08:20 PM andypugh: You could raise an issue on that Github asking for clarification on the status of Windows and Mac
08:20 PM JesseG: well the thing you linked to has instructions for mac that my friend' is gonna try
09:01 PM Jymmm: OMG, andypugh left, such a quitter!!! ;)
09:15 PM _unreal_: so whats going on?
09:20 PM Tom_L: just patiently waiting for you to show up
09:21 PM _unreal_: taaa daaaaa.....
09:21 PM Tom_L: messin wiht my FPGA board a bit
09:21 PM _unreal_: I'm trying to harden some ultra low carbon coupler nuts
09:21 PM XXCoder: yo
09:22 PM _unreal_: I have them baking away in charcoal
09:22 PM Tom_L: cherry red then dip in oil
09:22 PM Tom_L: almost orange
09:23 PM _unreal_: I did
09:24 PM _unreal_: I'm cooking it for an other hour
09:24 PM _unreal_: will give it 3 hours of charcoal cherry red hot expsure
09:24 PM Tom_L: what for?
09:27 PM _unreal_: they are to drive my new cnc machine
09:27 PM Tom_L: no, why bake it so long?
09:27 PM _unreal_: it really needs to bake for 8 hours
09:27 PM _unreal_: and inside a sealed container with carbon
09:28 PM Tom_L: trying to increase the carbon content..
09:28 PM _unreal_: normally people use a metal container filled with charcoal powder, coat the container with clay to seal it. and bake for 8 hours at like 1400F as I recalll
09:28 PM _unreal_: case harden
09:28 PM _unreal_: yes
09:29 PM Tom_L: you don't think regular steel couplers are strong enough?
09:29 PM XXCoder: ordered some jst xh cable extensions
09:29 PM XXCoder: cables on laser machine isnt quuuite long enough lol
09:29 PM _unreal_: they are PLENTY strong enough. the idea is to harden them so they dont ware
09:29 PM _unreal_: Tom_L, if I dont harden the surface then the threads on the nuts will ware fast
09:29 PM _unreal_: and I'll get backlash
09:30 PM _unreal_: if I harden them then they will not ware half as fast
09:30 PM Tom_L: just the oil dip will case harden them probably .020"
09:30 PM _unreal_: I already tried
09:30 PM _unreal_: didnt do squat
09:30 PM _unreal_: so I'm giving them a longer dose
09:30 PM Tom_L: get better nuts?
09:31 PM _unreal_: are you making fun of my nuts
09:32 PM Tom_L: maybe they're just not tough enough for the job
09:33 PM _unreal_: I may water quench next
09:34 PM _unreal_: ok 10:30 back in a few going to water quench
09:43 PM _unreal_: ok
09:43 PM _unreal_: didnt do much
09:44 PM _unreal_: its clearly harder then it was
09:44 PM _unreal_: but even after a second hardening its not very hard
09:44 PM _unreal_: a file grabs them half as much as it did before
10:35 PM veegee: So I'm powering my 600V 3 phase motor from a 120V residential socket
10:36 PM veegee: 120V -> 240V step up -> VFD -> 3 phase transformer to 600V
10:37 PM veegee: The VFD can be powered by DC. So I want to put some capacitors on the VFD input because I'm treating the VFD more as a regular 3 phase inverter than a soft start VFD because I'm powering multiple things from it
10:37 PM veegee: My plan is to put a full wave rectifier in front of the VFD input and then a few motor start capacitors in parallel. Right now the VFD complains of the input voltage dip when I start a motor right at 60Hz
10:38 PM veegee: so some capacitors in front of the VFD input should do the trick I hope
10:39 PM veegee: 7.5kW VFD is $400. An "industrial grade" bullshit 3 phase inverter is 10x that for no reason. It's the same damn thing. The VFD is far more complex actually
10:39 PM Elmo40: why the DC?
10:39 PM veegee: because I need a low impedance energy source in front of the VFD so it doesn't see the voltage dip too much when I start a big load
10:39 PM Elmo40: the VFD turns the input to DC then variable AC output.
10:40 PM veegee: Yeah but if I treat the VFD as a normal 60Hz inverter and suddenly flip a switch to turn on a big load like a 3 phase motor, the motor has a huge start up current which causes the voltage at the VFD input side to drop
10:40 PM Elmo40: then why a VFD at all? just use a transformer if you are simply going to 'flip a switch'
10:40 PM veegee: the VFD complains about that and shuts off with a "low input voltage" error
10:40 PM veegee: it's a 3 phase motor
10:41 PM Elmo40: the VFD gives you the oportunity to soft start and minimize the current load at startup
10:41 PM veegee: yeah but I want a full pure sine wave on all 3 phases
10:41 PM Elmo40: and the VFD can give that.
10:41 PM veegee: yes but if I drive multiple loads on the same VFD, you can't "soft start" that
10:41 PM Elmo40: remember, it goes like this: AC=>DC=>AC
10:42 PM Elmo40: ah. so there is the snag
10:42 PM veegee: yes but there's a rectifier inside the VFD anyway
10:42 PM veegee: it doesn't care if the input is AC or DC. It's not mentioned officially, but that's how they work anyway
10:42 PM Elmo40: i was wondering why you wanted the VFD before a 600V transformer...
10:42 PM Elmo40: you simply want it as a phase generator
10:42 PM veegee: so full wave rectifier -> big capacitors -> VFD
10:42 PM veegee: yes
10:43 PM veegee: "industrial" 3 phase inverters are a rip off
10:43 PM Elmo40: and why do you have 600V motors at home?
10:43 PM Elmo40: and dont say because they were free...
10:43 PM veegee: I tested the VFD output with my oscilloscope and some isolated high voltage probes and the output is nice
10:44 PM veegee: I got good deals on the vertical mill and other equipment
10:44 PM veegee: they were all 600V
10:44 PM veegee: bought from a machinist who took care of his equipment with daily lubrication, scrape marks all intact, etc.
10:45 PM veegee: The motors aren't easy to switch to 240V. Have to rewind everything and that's a huge waste of time
10:45 PM veegee: 4 pole motors, so many windings
10:46 PM veegee: compared to the time needed to rewind a single 3 phase 4 pole motor (or cost of paying someone to do it), I can buy so many capacitors
10:47 PM veegee: Or possibly considering building a high power LiFePO4 battery pack that can sustain 10kW output and treating it like a big capacitor. Since I don't need 10kW continuous, it's fine. That + solar charge controller will handle keeping the pack charged and provide burst power when needed. Even for big industrial 10HP air compressors
10:54 PM CaptHindsight: sounds like a plan
11:00 PM veegee: I don't know why they don't bring 600V to the home
11:00 PM veegee: We get better efficiency, more power, higher death rate of stupid people. Wins all around
11:10 PM CaptHindsight: 120VAC is already the standard, it will take quite some doing to change that
11:11 PM CaptHindsight: imagine all the changes required
11:11 PM CaptHindsight: and stupid people are good for business
11:12 PM CaptHindsight: imagine all the profits lost if you got rid of stupid
11:13 PM XXCoder: would be interesting if house changed over ro 5v
11:13 PM XXCoder: lot stuff can be ran on that nowdays
11:14 PM XXCoder: not some stuff tho like washer, ref, etc
11:20 PM CaptHindsight: new construction is getting 5V next to some outlets
11:21 PM CaptHindsight: https://www.amazon.com/Electrical-Outlet-Charger-Tamper-Resistant-Receptacle/dp/B07CTP4GFQ
11:28 PM tiwake: veegee: more darwin awards is never a bad thing
11:28 PM Kevin`: be careful with those, they need a lot more safety-critical quality than a normal outlet and your average asshole building a house to sell isn't going to investigate
11:29 PM tiwake: Kevin`: it will be easier to troubleshoot at least
11:30 PM veegee: well at least why not 240V? Why does Europe/Asia do 240V and not North America?
11:30 PM tiwake: 240 is standard
11:30 PM tiwake: I'm using 240v single phase right now actually
11:31 PM tiwake: (just put clothes in the dryer)
11:31 PM veegee: I mean yeah you get split phase 240V to the house
11:31 PM veegee: but most outlets are still 120V
11:31 PM tiwake: and my shop has 240 outlets in it
11:37 PM CaptHindsight: Edison initially pushed DC
11:37 PM CaptHindsight: but after a few years the pitfalls of trying to run DC into every home and business became apparent
11:40 PM CaptHindsight: http://large.stanford.edu/courses/2013/ph240/iskhakov2/
11:41 PM tiwake: I'm surprised modern houses are not running dedicated DC lines from a single converter box inside or near the house
11:41 PM tiwake: because of how many things need DC power, it would seem more efficient
11:42 PM _unreal_: ok I've had enough fun screwing with the cnc for a while
11:42 PM _unreal_: I just finished running the TAP down the coupler/drive nuts
11:42 PM _unreal_: they clearly took a hardness
11:43 PM _unreal_: not super hard but clearly harder
11:43 PM tiwake: took a hardness?
11:43 PM _unreal_: quenching
11:43 PM tiwake: from what?
11:43 PM _unreal_: water
11:43 PM _unreal_: tried oil. didnt do well
11:43 PM _unreal_: so went with ICE water
11:43 PM _unreal_: much better
11:43 PM tiwake: oh you are trying to harden steel
11:44 PM _unreal_: low carb steel
11:44 PM tiwake: what is the carbon content?
11:44 PM _unreal_: I'm using very large/long coupler nuts to drive my new cnc
11:44 PM _unreal_: no idea
11:44 PM _unreal_: low
11:44 PM XXCoder: from what i understand cooling faster does make it harder but thats about the extent of my knowlege lol
11:44 PM XXCoder: also depends on makeup I guess
11:44 PM tiwake: 0.2% and less is considered low carbon
11:45 PM _unreal_: lower grade needs higher cooling rate to get better hardening
11:45 PM tiwake: 1018 steel is 0.18% carbon
11:45 PM _unreal_: these are coupler nuts from lowes
11:45 PM tiwake: if I remember how the numbers go
11:45 PM _unreal_: 1/2-13
11:46 PM tiwake: oh yeah then crap metal unless its specifically grade 8 or 10
11:46 PM _unreal_: I just finished running the 1/2-13 tap down the nuts. and it was a challenage
11:46 PM _unreal_: no one has grade 5+ coupler nuts
11:47 PM tiwake: so grade 3?
11:47 PM _unreal_: and I didnt feel like ordering on line
11:47 PM _unreal_: I needed nuts that have a tight fit to my stainless 1/2-13 threaded rods
11:47 PM tiwake: you need tighter nuts
11:47 PM tiwake: I understand the desire
11:47 PM _unreal_: if the threads dont match you get backlash
11:48 PM tiwake: and backlash in bed because of loose nuts is not a good thing
11:51 PM _unreal_: next I need to order timing belts and pullies
11:53 PM tiwake: lol there is another thing I could say, but I'm cutting myself off at this point
11:54 PM _unreal_: 208xl timing belts
11:54 PM _unreal_: I need to find a cheap source of belts that match that tooth count
11:54 PM _unreal_: I'm not 100% sure of the size belt I need but I need one large one
11:56 PM _unreal_: no one around... sigh
11:58 PM tiwake: what machine is it?
11:58 PM tiwake: also, its nearly midnight here
