#linuxcnc Calendar

12:08 AM Bleepshop: roycroft: AutoCAD's lawyers probably started arriving via parachute, waving threatening documentation.
12:15 AM * Bleepshop is still cleaning...
12:15 AM roycroft: that would have been very nice
02:01 AM randy: morning
02:03 AM Deejay: moin
04:39 AM -!- #linuxcnc mode set to +v by ChanServ
05:05 AM Tom_itx: morning
05:13 AM Tom_itx is now known as Tom_L
05:22 AM Tom_L: 24°F
07:32 AM JT-Cave: yesterday I was removing an OLED from Coop Uno to make room on the terminal block to connect a DS18B20 and after I removed all the wires going to the breakout board I noticed a few still in the breakout board going into the coop... I thought I hope that's not the door sensors
07:34 AM JT-Cave: turns out it was a BME280 I had installed a long time ago
10:02 AM roycroft: teh wormhole to teh matrix has been rather unstable of late
10:02 AM Guest67: Anyone available with experience making userspace python components? The example in the docs has a time.sleep(1) in the components main loop. Is it necessary to sleep?
10:02 AM Guest67: http://linuxcnc.org/docs/html/hal/halmodule.html
10:05 AM Guest67: I guess I'm trying to understand how the cycles fit together. Each userspace component is in it's own thread? will I lock something up without a call to sleep?
04:15 PM Tom_L: .
04:27 PM JT-Shop: ,
04:28 PM JT-Shop: next 3 nights in the teens here
04:30 PM Tom_L: yeah summer can't last forever
04:31 PM -!- #linuxcnc mode set to +v by ChanServ
04:58 PM JT-Shop: still calling for snow tomorrow and it should stick with the low temps
04:58 PM XXCoder: interesting
04:58 PM XXCoder: here its raining. if its not raining,its raining some more
04:58 PM roycroft: it's going to rain heree tomorro
04:59 PM roycroft: and i should set up a cron job to repeat that every day until july
04:59 PM XXCoder: I miss days when it rained in summers
05:00 PM JT-Shop: I think my method of cutting thin spines is flawed... I think jointing the face then cutting with a resaw blade on the bandsaw might be better than the table saw for a 2 1/2" thick piece of oak
05:00 PM JT-Shop: sizing with the drum sander worked well
05:24 PM roycroft: i'd probably use a band saw
05:24 PM roycroft: if only i were able to use my new one :)
05:24 PM roycroft: i could still use my old one - i'm not going to sell it until my new one is working properly
05:26 PM XXCoder: what the
05:26 PM XXCoder: seems theres teacher who had J and J vaccine and gave some student a shot at her home
05:27 PM XXCoder: so many questions. like how she got one, and why is that kid taking shot there
05:27 PM XXCoder: that teacher may end up in jail for 4 years
05:27 PM JT-Shop: aye I'll use the band saw next time...
05:27 PM roycroft: yeah, i read about that
05:28 PM roycroft: the student is a minor, and the parents did not consent
05:28 PM XXCoder: indeed. while I am very strongly supportive of vaccines, that was just very strange and yeah law breaking
05:28 PM roycroft: i think the fundamental question is who initiated the discussion of giving the student the jab
05:28 PM roycroft: the teacher still was wrong to give it
05:29 PM XXCoder: yah
05:29 PM roycroft: but i think that motive is important
05:29 PM roycroft: i can see the teacher asking who has gotten it, and the student saying "i did not get it because my parents don't believe in it"
05:30 PM JT-Shop: https://gnipsel.com/images/chickens/elevated-dust-bath/edb-05.jpg
05:30 PM roycroft: and then the teacher convincing the student to let the teacher administer it
05:30 PM JT-Shop: https://gnipsel.com/images/chickens/elevated-dust-bath/edb-06.jpg
05:30 PM XXCoder: JT-Shop: nice job
05:30 PM roycroft: i can also see the student wanting the jab, frustrated that the parents do not consent, and approaching the teacher for advise
05:30 PM JT-Shop: getting there, need more practice
05:31 PM XXCoder: roy yeah though probably affects if she gets jail time or not. though it may be just length of time in jail not in or out
05:31 PM * roycroft is still trying to make sense out of solidworks
05:31 PM roycroft: i've gotten past the hole wizard :)
05:31 PM JT-Shop: :)
05:31 PM roycroft: now it's smart fasteners that baffle me
05:31 PM roycroft: that same assembly i was working on
05:31 PM roguish[m]: skip 'em
05:32 PM roycroft: i'm not going to add all the fasteners in by hand - there will be hundreds of them
05:32 PM roycroft: i open the back plate
05:32 PM roguish[m]: that's what patterns are for.\
05:32 PM roycroft: i create an assembly with it
05:32 PM JT-Shop: I never put fasteners in an assembly
05:32 PM roycroft: i add the bearing blocks
05:32 PM roycroft: they line up perfectly
05:32 PM cradek: poor kid. poor stupid teacher. stupid parents.
05:32 PM roycroft: it makes it easier to generate a bom, jt-shop
05:33 PM roycroft: i even use the hole alignment tool, and set the variance to 0.001"
05:33 PM roycroft: it's perfect
05:33 PM roycroft: i then open the smart fastener tool and try to add the fasteners
05:34 PM XXCoder: cradek: not enough context to know what exactly happened besides shot being given
05:34 PM roycroft: it works for 1/2 of the holes
05:34 PM roycroft: the other half not at all
05:34 PM roycroft: then, in a different experiment, i decided to see if it runs faster if i save the bearing block assembly as a solid part
05:34 PM roycroft: it does, btw, run *way* faster
05:35 PM roycroft: so i did the same assembly, using the bearing block part instead of the bearing block assembly
05:35 PM roycroft: again, everything lines up perfectly
05:35 PM roycroft: but this time, the smart fastener tool populates all of the holes
05:35 PM roycroft: weird, eh?
05:36 PM roycroft: since the solid part is much faster than the assembly, i prefer to use it, so i can move on
05:37 PM roycroft: but i am trying to figure out why the smart fastener tool behaves differently with a subassembly vs a part
05:37 PM roycroft: and i made no changes at all to the subassembly
05:37 PM roycroft: i opened it, and then immediately saved it as a part
05:37 PM roycroft: i did not even click on it to highlight a surface
05:43 PM * JT-Shop wonders about laminating the arched legs for the elevated dust bath...
05:50 PM snakedGT is now known as snaked
05:50 PM JT-Shop: hey snaked
05:50 PM * snaked waves
05:51 PM * JT-Shop gets ready for frozen stuff tomorrow
05:51 PM snaked: My frozen stuff will be coming in ice and snow form. It's rare that we share this burden!
05:52 PM JT-Shop: looks like snow tomorrow and with temps in the teens at night and below freezing during the day it may stick for a few days
05:52 PM CaptHindsight[m]: https://rockford.craigslist.org/for/d/rockford-mazak-qt10-cnc-lathe/7418236757.html
05:53 PM JT-Shop: a poor excuse to play in the wood shop is good enough for me tomorrow
05:53 PM * JT-Shop goes to get the chicken soup ready... not my chickens you know
05:57 PM roycroft: i'm assuming you mean you're making some soup for your chickens :)
05:57 PM roycroft: corn chowder would be a good choice
06:00 PM CaptHindsight[m]: anyone hear from Gene the past few months?
06:01 PM CaptHindsight[m]: not Heskett, the Gene that used to be in here
06:01 PM XXCoder: whats nick?
06:01 PM CaptHindsight[m]: Gene(something something)
06:02 PM CaptHindsight[m]: he had a turining shop inn his garage, used to be in here near every day until a few months ago

06:11 PM roycroft: and guess what
06:11 PM CaptHindsight[m]: yeah, it's that bad here
06:11 PM XXCoder: chin diapers nice
06:11 PM roycroft: the two counties to the north of us each have zero icu beds available
06:11 PM roycroft: and our hospitals are almost full as well
06:12 PM CaptHindsight[m]: similar here
06:12 PM roycroft: this wave should peak in about a two weeks

06:15 PM roguish[m]: roycroft: Djokovic just got denied entry into Aus
06:15 PM roguish[m]: no vax, no play
06:15 PM CaptHindsight[m]: I'm thinking maybe 2030 or 2040 unless Darwin really kicks in to gear
06:16 PM roguish[m]: good for the Ausies.
06:16 PM roycroft: yes, i read that, roguish
06:16 PM roycroft: if they make dogs quarantine i see no reason they should not make humans quarantine :)
06:16 PM Tom_L: you know it's all coming from the ice caps thawing out releasing all those captured organisms :)
06:16 PM roguish[m]: on a better note, the James Webb scope is getting it done.
06:17 PM roycroft: the southernmost glacier in oregon is gone
06:17 PM roguish[m]: Tom_L: that's a good one....
06:17 PM Tom_L: roguish[m], nice
06:17 PM roycroft: that was reported on the news today
06:17 PM Tom_L: i was watching a show on that the other day
06:17 PM Tom_L: i also watched one on the stuff they're finding buried in the ice :)
06:17 PM roycroft: that episode of madame secretary where the tundra in siberia was melting and started a smallpox outbreak?
06:18 PM CaptHindsight[m]: Tom_L: I heard it was meteorites that escaped from Uranus
06:18 PM roguish[m]: NASA does good work, they just add a zero to the schedule of years, and a couple of zeros to the cost.....
06:18 PM roycroft: c'mon, man
06:18 PM roycroft: you know that's a bunch of malarkey
06:18 PM Tom_L: really hard to say what can survive in that frozen environment
06:18 PM roycroft: there are no meteorites from uranus
06:18 PM roguish[m]: capt_hindsight[m]: those are Klingons.
06:18 PM roycroft: it is those jewish space lasers that are messing with us
06:21 PM roguish[m]: have you guys seen those fancy workout machine things Tonal ???
06:21 PM CaptHindsight[m]: sounds familiar on late night TV
06:21 PM roguish[m]: I just started a project on a competitor..............
06:21 PM CaptHindsight[m]: with the LCD
06:21 PM roguish[m]: pretty cool.
06:22 PM CaptHindsight[m]: does it have a roid dispenser? :)
06:24 PM roguish[m]: no roids......unless ya grunt real hard doing a workout.
06:24 PM CaptHindsight[m]: https://www.reddit.com/r/tonalgym/comments/nwd0iw/is_my_tonal_about_to_fall_off_the_wall_bulging/
06:24 PM roguish[m]: that's it
06:25 PM roguish[m]: that sounds like an installer FU

06:26 PM CaptHindsight[m]: I see Bowflexes on CLfor $200
06:27 PM CaptHindsight[m]: we just keep freeweights around
06:27 PM CaptHindsight[m]: no cloud, just gravity
06:29 PM roycroft: i'll decide closer to the event date
06:29 PM roycroft: the venue are requiring proof of vaccine for everyone
06:29 PM roycroft: they're not accepting recent negative tests - proof of vaccine is required, and current vaccine status
06:29 PM roycroft: so if you're eligible for a booster you must have the booster
06:30 PM CaptHindsight[m]: get the SCUBA!
06:30 PM CaptHindsight[m]: only way to be sure
06:30 PM roycroft: of the three eugene symphony concerts for which i have tickets this season, this first one is the one i would least mind missing, if it comes to that
06:31 PM CaptHindsight[m]: I had a friend once go to concert in the middle of winter in just his wet suit
06:31 PM XXCoder: roycroft: french has a interesting strat - increasily deny stuff to 10% remaining unvaccined
06:32 PM roycroft: i don't think that would be appropriate for the symphony
06:32 PM CaptHindsight[m]: roycroft: It may be soon enough
06:32 PM roycroft: i may not wear a suit, but dress slacks, a tie, and a nice sweater at least
06:32 PM XXCoder: well can always buy what I linked picture of
06:32 PM roycroft: we should not be denying things to the unvaxed
06:32 PM CaptHindsight[m]: PAPR
06:32 PM roycroft: we should be giving them things
06:32 PM XXCoder: "hey antimaskers, I arent wearing a mask, why complain?"
06:33 PM CaptHindsight[m]: like a brain
06:33 PM roycroft: like a good *thwap* on their heads in an attempt to knock some sens into them :)
06:33 PM CaptHindsight[m]: wellJesus will save them
06:33 PM XXCoder: jesus take the wheel
06:33 PM roycroft: yeah, i heard that ron johnson crap again last night
06:33 PM CaptHindsight[m]: or take them, Jesus's call
06:33 PM roycroft: i never knew he was a scientologist
06:33 PM XXCoder: wrong wheel!
06:34 PM roycroft: does ron johnson believe in using aspirin?
06:34 PM roycroft: blood pressure meds?
06:34 PM roycroft: antibiotics?
06:34 PM roycroft: does he use plastics for anything?
06:34 PM roycroft: god did not create plastics - they are a human invention
06:35 PM CaptHindsight[m]: roycroft: this one? https://www.ronjohnson.senate.gov/
06:35 PM roycroft: i won't bother going there
06:35 PM roycroft: but yes, that one
06:35 PM roycroft: the cro-magnon from wisconsin
06:36 PM CaptHindsight[m]: roycroft: well the lord works in mysterious ways
06:36 PM roycroft: and maybe one of those ways was to give pfizer et al. a vaccine
06:36 PM CaptHindsight[m]: "heal me Jesus"
06:37 PM CaptHindsight[m]: A ...... men
06:37 PM CaptHindsight[m]: my parents were very religious, but they also lived through very traumatic times
06:38 PM XXCoder: I remember that story where man on flooded region, on roof, denied rescue from couple boats, then helicoper, saying "no, jesus will save me". when he died, he asked him, and jesus said "I sent you 2 boats and helicopers, why didnt you accept them?"
06:38 PM CaptHindsight[m]: what limited them just train wrecks vs top news story train wrecks
06:41 PM CaptHindsight[m]: my dad didn't believe in doctors until he was in his 50's
06:42 PM CaptHindsight[m]: then surgery was better than death
06:42 PM roycroft: what? when he saw a doctor on the street he thought the doctor was a hologram or something?
06:43 PM XXCoder: different type of belive
06:43 PM CaptHindsight[m]: doctors are for sissies kinda thing
06:45 PM CaptHindsight[m]: unless blood is leaking/squirting or flesh is hanging loose, you just tough it out
06:45 PM CaptHindsight[m]: how he survived WWII
06:45 PM XXCoder: my grandfather was quite different, he refused to go to doctors, because he didnt want to pay
06:46 PM CaptHindsight[m]: that was partially my dad as well
06:46 PM CaptHindsight[m]: would walk that extra 2 miles uphill to save the 5 cents on bread
06:46 PM XXCoder: when he was 70s, he broke a leg, then he found out he had prosite cancer. he couldnt get surgery due to clots from broken leg
06:47 PM XXCoder: doctor told hime he will die in a month. he lived for a year
06:47 PM XXCoder: whats sad grandmother, who was former nurse was making care of him died 2 weeks before him, had heart attack right in front of him
06:48 PM CaptHindsight[m]: mine had 3 surgeries after 60, then he wore a hernia belt for 20 years until 90
06:48 PM XXCoder: that was week before my birthday, and grandfather died a week after
06:48 PM XXCoder: it was bad year
06:48 PM CaptHindsight[m]: wow
06:50 PM CaptHindsight[m]: mine divorced ~40 years before they passed
06:50 PM roycroft: i don't believe in overmedicating
06:50 PM XXCoder: yeah. m grandfather was real tough guy, funny for techologist atheist pacifist guy
06:50 PM CaptHindsight[m]: probably would have only lived another 10 or so if they had stayed together
06:50 PM roycroft: but there's nothing wrong with seeing a medical professional when you have medical issues that can be treated
06:51 PM XXCoder: pacifist guy who went to ww2 at both locations. wish I can know more, but he refused to talk about ww2 besides "went there"
06:51 PM roycroft: a lot of wwii vets refused to talk about the war
06:52 PM CaptHindsight[m]: my dad got mad at my mom for taking my brother to the doc after he got a pitchfork through the foot
06:52 PM CaptHindsight[m]: dirty fork, all the way through
06:52 PM XXCoder: roy yeah. never understood why my grandfather didnt take concous objection to draft. hes pacificist after all
06:53 PM CaptHindsight[m]: my dad objected to the war after it was over and didn't go back to his home, came to the US
06:54 PM CaptHindsight[m]: though his return would have been "Thank you for you service" followed by a bullet to the head.
06:55 PM XXCoder: my dad quit school to help ww2, he essentally had friend help him get though interviews. worked on navy boat as dishwasher 2 weeks before captain caught him throwing trash away, navy is VERY strict on roles. he spoke to my dad, but my dad didnt reply or turn around. captain screamed few times, caught the fact that my dad is deaf
06:55 PM XXCoder: gave him honorable discarge out of navy
06:56 PM CaptHindsight[m]: an unfortunate liability
06:56 PM XXCoder: yeah it was well before it was more acceptable
06:56 PM CaptHindsight[m]: was he in the pacific?
06:57 PM XXCoder: no idea sadly
06:57 PM XXCoder: dont think boat havent went anywhere before he was given the boot
06:57 PM CaptHindsight[m]: was just watching WWII in Color, the Midway and Dec 6 episodes
06:57 PM XXCoder: oh interviews cheat? his friend told him what questions was, so my dad just spoke answers in order
06:58 PM XXCoder: my dad was late deafened so he could speak well enough
06:59 PM roycroft: there's an interesting youtube series on the battle of midway
06:59 PM roycroft: it's presented from the japanese perspetive, through the fog of war
06:59 PM CaptHindsight[m]: I've seen several
06:59 PM roycroft: three parts, about 40 minutes each
06:59 PM roycroft: well worth watching
06:59 PM CaptHindsight[m]: yeah the Japanese persepective
06:59 PM XXCoder: CaptHindsight[m]: my best guess is boat was still setting up, since they was hiring a lot of navy workers then
07:00 PM roycroft: that was such a pivotal battle
07:00 PM roycroft: and the japanese really screwed up
07:01 PM roycroft: i'm trying to decide whether i should display my flag tomorrow, upside-down
07:01 PM roycroft: my neighbors already hate me enough
07:02 PM roycroft: and christmas is just ending, so i still have my big peace sign lit up on the front of my house
07:02 PM roycroft: perhaps it would be best not to fly the flag that way tomorrow
07:03 PM CaptHindsight[m]: roycroft: ever see "The Eternal Zero"
07:03 PM CaptHindsight[m]: https://en.wikipedia.org/wiki/The_Eternal_Zero
07:03 PM CaptHindsight[m]: never forget
07:04 PM roycroft: no
07:04 PM roycroft: and the former president has cancelled his rally that was scheduled for tomorrow
07:04 PM roycroft: so i'll be generous and not poke at my neighbors
07:04 PM CaptHindsight[m]: I grew up on US made war films, watching them made by ex-axis countries is very interesting
07:05 PM XXCoder: roy ya saw that. good
07:06 PM roycroft: that looks like a potentially interesting film, capthindsight
07:10 PM CaptHindsight[m]: high quality film
07:10 PM CaptHindsight[m]: Russian made WWII films are the most brutal
07:11 PM XXCoder: was it from era when it was still soviet, or later>
07:12 PM CaptHindsight[m]: XXCoder: The Eternal Zero was made in japan about 8 years ago
07:12 PM XXCoder: not talking about japan film
07:13 PM CaptHindsight[m]: https://www.rbth.com/arts/332154-top-russian-wwii-movies
07:14 PM CaptHindsight[m]: XXCoder: https://www.imdb.com/title/tt0091251/
07:14 PM CaptHindsight[m]: if you want something to leave an impression on you
07:15 PM XXCoder: interesting
07:15 PM CaptHindsight[m]: it's from a young boys perspective
07:16 PM CaptHindsight[m]: well early teen
07:18 PM CaptHindsight[m]: my dad wasn't much older during WWII, he started out with one guy getting a rifle and your partner getting the bullets, since he was a disposable minority
07:19 PM XXCoder: i wonder what would happen if my dad didnt get caught
07:19 PM XXCoder: where he would go and so on. oh why he was taking trash out is because trahs guy was sick
07:20 PM CaptHindsight[m]: don't know, would he have heard the general alarm?
07:20 PM XXCoder: no idea. he dont work anywhere really vital, being a dishwasher
07:20 PM CaptHindsight[m]: yeah but if he had to get out
07:20 PM XXCoder: yeah
07:20 PM CaptHindsight[m]: abandon ship etc
07:21 PM XXCoder: i wish I asked more details. little bit too late now
07:21 PM CaptHindsight[m]: or help wounded, or even warn of something he sees
07:21 PM XXCoder: he died in 2003. nearly 20 years ago
07:22 PM CaptHindsight[m]: we found out a lot about our parents after they passed when we finally exchanged stories
07:22 PM CaptHindsight[m]: we filled in lots of each others blanks
07:22 PM XXCoder: nice. unfortunately my brother and sis didnt know anything more
07:23 PM CaptHindsight[m]: mom survived the bombing of Dresden
07:23 PM XXCoder: grandpa simply refused to talk, and my dad experence totaled to all of 2 weeks and no going to wr
07:24 PM CaptHindsight[m]: when we were kids my parents would only talk with their friends about the war, and only in languages they did not pass on to us
07:24 PM CaptHindsight[m]: they both spoke >5
07:24 PM XXCoder: interesting
07:25 PM CaptHindsight[m]: my dad could speak in 7-9
07:25 PM XXCoder: no idea what you mean by numbers
07:25 PM CaptHindsight[m]: different langiages
07:25 PM CaptHindsight[m]: heh languages
07:25 PM XXCoder: ok
07:35 PM FinboySlick: CaptHindsight[m]: Damn, you're not messing around with your movie recommendations.
07:36 PM CaptHindsight[m]: FinboySlick: have you seen any?
07:36 PM CaptHindsight[m]: we might have fewer wars IF people watched them
07:42 PM CaptHindsight[m]: then again I find Fox news and conservative talk radio equally revolting
07:45 PM FinboySlick: I haven't seen them but I know about "Come and See" and how it was made. Been meaning to watch it even though I am quite familiar with that history.
07:47 PM CaptHindsight[m]: it's pretty awful, it's usually on Top for most brutally realistic
07:48 PM andypugh: Was it XXCoder or CaptHindsight[m] looking for a low-Z probe for a router?
07:48 PM andypugh: https://a360.co/3HHQlHs
07:48 PM FinboySlick: I think the biggest mistake people make is thinking that 'modern' war is any better.
07:48 PM andypugh: That’s a modification of my recent probe design, to fit direcltly to the spindle taper.
07:48 PM CaptHindsight[m]: andypugh: Not I
07:49 PM CaptHindsight[m]: andypugh: you getting any sleep?
07:49 PM andypugh: Sleep is for the weak!
07:49 PM FinboySlick: andypugh: Quite enjoyed the video you made about that probe, btw.
07:54 PM andypugh: I am not sure how many got the point. It’s not about making a probe, it’s about how you can use geometry and borrowed accuracy to make something that measures to a micron using a tool that deflects my 1000x that.
07:56 PM FinboySlick: andypugh: The novel thing to me was doing it with pins instead of balls. I knew those were already surprisingly accurate but how would you say the pins compare?
07:56 PM FinboySlick: (I'm probably still missing the point)
07:58 PM XXCoder: andypugh: me
07:58 PM XXCoder: also, congats you was featured on hack a day
07:59 PM andypugh: I cheat, Dave Rowntree is a friend from college 30+ years ago, and Jenny List was one of my RobotWars team 20 years ago. So my stuff tends to get picked up.
07:59 PM XXCoder: andy I was thinking if its possible to use very thin gage rods fir er16 completeky inside (besides probe and wires) probe
08:00 PM * FinboySlick fans himself rom all the fame-flexing Andy is doing.
08:00 PM XXCoder: you adjust centerness by rising or lowering pins
08:00 PM FinboySlick: Oh my, stop before I rename myself Fanboy.
08:00 PM XXCoder: fanboyslack
08:01 PM FinboySlick: Thank god Stefan isn't around too, I might faint.
08:01 PM XXCoder: andypugh: 3 sets of pins, and center probe has disc for contacts. you AND all 3 contacts and if one breaks contact, its triggered
08:03 PM FinboySlick: Kidding aside though, what did you mean by adjusting centerness, XXCoder? The probe pins do not seem adjustable.
08:04 PM XXCoder: not his probe, no
08:04 PM XXCoder: my idea might be
08:04 PM XXCoder: his design can be modified to be
08:04 PM XXCoder: just need one of each pair to have set screw
08:04 PM XXCoder: and slightly looser
08:05 PM FinboySlick: If you don't want to depend on probe length for centerness though, you'll have to make your adjustment perpendicular to the probe axis.
08:05 PM XXCoder: in least think so.
08:05 PM andypugh: Going back a bit, if you use pins then as long as the holes are drilled in the right place, it’s easy to get the pin axis in the right place. I think that’s easier than locating a ball.
08:05 PM XXCoder: yeah
08:06 PM andypugh: My Renishaw probe has a ball at the top and 4 screws, you rock the whole thing. If you change the stylus, you re-centre.
08:07 PM andypugh: The styluses only screw in anyway, no real effort to locate them on a register.
08:07 PM XXCoder: andy for your design, I was thinking maybe can have set screw adjust how close your pin pair is to each other
08:09 PM FinboySlick: andypugh: Though it doesn't add adjustability per say, what I was thinking was that if you drilled and threaded a hole in the midle of where the spring is, you could lock the probe once assembled, then re-bore the stylus hole.
08:09 PM FinboySlick: (carefully, of course, that's not a very rigid setup and you don't want to flex the assembly)
08:10 PM andypugh: Yes, in-situ threading the stylus hole would help.
08:10 PM andypugh: Though you would probably also want to in-situ face the mating face.
08:11 PM FinboySlick: Are those centered by the thread itself or do they have locating shoulder/shaft?
08:11 PM FinboySlick: (typically, I imagine that's brand-dependant)
08:16 PM andypugh: They have nothing, in general.
08:16 PM andypugh: They centre on the thread and pull up with a shoulder against the face.
08:17 PM XXCoder: andy had a idea how to do adjustable rods better. bolts on bottom where you can screw something holding rods in angle upwards or downwards
08:17 PM XXCoder: so rods can go anywhere from say 5 degrees from center to parallel
08:17 PM andypugh: But, for a CMM it doesn’t matter, and for a spindle probe, there is adjustment.
08:18 PM andypugh: I think tilting the whole body is probably the way.
08:18 PM XXCoder: could work too though cant visualize how
08:18 PM XXCoder: large ball socket thats lockable?
08:19 PM andypugh: My Renishaw has a ball at the top. then 4 screws that pull the body against the ball. You adjust the screws like a 4-jaw chuck.
08:20 PM andypugh: But it’s only a small ball.
08:20 PM XXCoder: oh interesting. harder to make your own I guess
08:20 PM FinboySlick: XXCoder: Two plates and set screws. One plate with the pins, one with the stylus.
08:20 PM FinboySlick: Adjust like a tripod.
08:20 PM XXCoder: indeed. nice
08:20 PM FinboySlick: Might be doable by doing a single puck and partial groove with a parting tool.
08:21 PM FinboySlick: You just push in the set screws to bend the part.
08:21 PM XXCoder: compressable, but quite rigid
08:24 PM FinboySlick: If you line up the set screws with the pins, you already have a hardened surface to push against.
08:24 PM andypugh: Anyway, ’tis late here…
08:25 PM FinboySlick: So he is weak. He said sleep is for the weak.
08:47 PM XXCoder: rain/snow here now
09:43 PM roycroft: it is just raining here
09:43 PM roycroft: we won't get any more snow any time soon
10:05 PM XXCoder: yeah it stopped here. just cloudy now
11:15 PM solarwind: I love oxy acetylene so much
11:16 PM solarwind: When you need precision and tolerance for somewhat dirty material, no other welding process can match it
11:16 PM solarwind: TIG will foul tungsten and such and can't do it outdoors. TIG brazing almost always melts the base metal
11:17 PM solarwind: Oxy acetylene can be done outdoors, easily in any position, dirty material won't hurt it
11:17 PM solarwind: If only acetylene weren't so damn expensive :(
11:26 PM Lcvette[m]: What's poppin?
