03:06 AM CaptHindsight: $16K http://www.automationtechnologiesinc.com/products-page/industrial-robot/industrial-robot
03:07 AM CaptHindsight: 6 Axis Industrial Collaborative Robot, 5Kg load, 924mm reach
04:21 AM Tom_L: morning
04:21 AM XXCoder: hey
05:02 AM JT-Cave: morning
05:03 AM JT-Cave: Tom_L, no such thing as a rank... the only measure of firewood is a cord
05:04 AM XXCoder: yo
05:33 AM Tom_L: ranks are for the military...
05:33 AM XXCoder: captain cord
05:35 AM Tom_L: programming a 1.5" x 16 tpi thread for a extinguisher pressure tester
05:35 AM Tom_L: https://www.hydro-test.com/ecommerce/replacement-parts/test-adapters-for-fire-extinguishers/100-236-adapter-test-1-1-2-dia-16-tpi-female-brass.html
05:36 AM Tom_L: mine won't be hex
05:36 AM Tom_L: cause my brass stock is somewhat round
06:14 AM Loetmichel: hehe, ich glaub ich bin ein rassist... Kollege grade... "gugg ma, der neue C5"... "taugt nix, isn franzose." "aber sieht geil aus!" "Bleibt ein franzose. Beim Essen: GERNE ein französischer koch, beim auto: deutsch!" Kolelge: "...[kopfschüttel]" :)
06:17 AM Loetmichel: hehe, i think i am a racist... Coworker just: "hey, look, the new Citroen C5!" "Nah, not good, its a french car." But it looks great!" "Still a french car. A french chef: every time. Cars: buy german!"... Him: "...[SMH]" :)
06:17 AM Loetmichel: sorry for german
07:16 AM JT-Cave: asus pro h410m-c is a windblows 10 motherboard and refuses to work with debian... x11
07:42 AM unterhaus: I'm not sure why you would want a contactor with 1 normally closed contact
07:56 AM JT-Cave: you want to know for sure that the contact is not pulled in...
08:32 AM miss0r: JT-Cave: I now have most of the cnc lathe working
08:32 AM miss0r: just a few minor kinks and ajustments
08:33 AM miss0r: like; for some reason the axis can only move in one direction, so I have some sort of fault in my direction wiring ;D
08:33 AM miss0r: and I would also like for it to accept that I want to use the brake on the spindle while stopping. I don't just want to release it
08:33 AM miss0r: Other than that it seems to be working. tool turret'n all
08:50 AM JT-Cave: cool
09:30 AM JT-Shop: crap just took all the clamps off the dust collection manifold and realized I had a Loetmichel moment... I glued the back on backwards
09:38 AM rs[m]: the spilling of blood is missing
09:39 AM roycroft: as i'm wont to read the news from multiple perspectives, i loaded the foxnews.com website yesterday around dinner time to see what they had to say
09:39 AM roycroft: i forgot to close the window
09:40 AM roycroft: i just got a pop-up notice from firefox informing me that it had blocked over 10,000 trackers on that website since i opened the window
09:41 AM roycroft: i can't even load foxnews.com with safari, which is my usual browser, as safari gets really sluggish and then locks up when i do
10:11 AM JT-Shop: I need to get my camera server back up and running I can't have 6 cameras running in explorer and use solidworks no cpu time left
10:15 AM roycroft: can you cut the back off the manifold without damaging the main body, jt-shop?
10:32 AM ziper: why is this so cheap? https://miami.craigslist.org/brw/hvo/d/coral-springs-vertical-cnc-mill/7275734485.html
10:32 AM ziper: scam?
10:33 AM bjorkintosh: likely not working.
10:33 AM norias: old and taking up space?
10:34 AM bjorkintosh: it's really old. you can almost see ghosting on the crt.
10:34 AM ziper: 20 years is really old?
10:34 AM bjorkintosh: depends on what they were using it for.
10:34 AM JT-Shop: roycroft, that's my plan to cut the back off on the bandsaw and if that works it won't go in the burn barrel
10:35 AM bjorkintosh: they weren't exactly towing it at the back of an RV to florida or something.
10:42 AM Rab: Remarkably clean for its age.
10:44 AM Rab: The pair of vises alone make it a bargain. But the rigging fees will be substantial.
10:44 AM JT-Shop: Tom_L, I figured out what happened to my part the other day
10:46 AM ziper: i talked to the guy, sounds like he is moving shop and just doesn't use them/need them at the new place
10:46 AM roycroft: use the table saw
10:46 AM ziper: said they worked fine
10:46 AM roycroft: it will be a cleaner cut
10:47 AM roycroft: just make a filler strip the width of the kerf to stuff in when you get to the third side
10:49 AM ziper: but they're too fucking tall, cant fit them in the garage
10:58 AM unterhaus_: JT-Shop, why did it happen?
10:59 AM unterhaus_: roycroft, what was that place you got your hole punches from?
10:59 AM unterhaus_: brewing supply or something?
11:00 AM JT-Shop: unterhaus_, why did what happen?
11:00 AM unterhaus_: you said you figured out what happened the other day
11:01 AM unterhaus_: I assume you are talking about the heavy cut
11:01 AM roycroft: chassis punches?
11:02 AM unterhaus_: roycroft, yes
11:02 AM roycroft: auberins.com
11:03 AM JT-Shop: on the last pass a piece of cut off jammed in the end mill for a moment and moved the fixture over for the remaining cut which cut too much off the left side then
11:06 AM unterhaus_: JT was it ruined?
11:07 AM JT-Shop: roycroft, I've used that technique to separate the lid from a box
11:07 AM JT-Shop: yes, making two new ones after lunch
11:07 AM unterhaus_: at least it wasn't the control acting up
11:07 AM JT-Shop: going to pry that part off before the final profile pass
11:07 AM JT-Shop: yeah that would have been very bad
11:12 AM JT-Shop: speaking of lunch...
11:12 AM roycroft: yes, jt-shop, this is pretty much the same operation as cuting the lid off a box
11:31 AM * roycroft will be bringing the lower casting of his bandsaw indoors today so it can cure at room temperature
12:10 PM Tom_L: temps dropping next couple days
12:11 PM JT-Shop: no days above freezing here on the forecast up to Wednesday
12:16 PM roycroft: same here, but it's still cool outside
12:16 PM roycroft: my fabriction shop is sitting at about 12 degrees with the heater on
12:17 PM roycroft: my fermenting room is 20 degrees, which is much better for curing paint
12:17 PM roycroft: we were supposed to get snow starting today, but now there's none at all in the forecast
12:17 PM roycroft: just rain, rain, and more rain
12:21 PM CaptHindsight: we won't be above 20F until the middle of next week, above freezing by the end of the month
12:23 PM JT-Shop: crap went to do Op2 on the parts and they are scrap...
12:23 PM JT-Shop: I give up
12:29 PM Tom_L: better fire the operator
12:30 PM Tom_L: 8am tomorrow 5F
12:31 PM Tom_L: JT-Shop, what happened this time?
12:34 PM Tom_L: 8am sat 2F
12:38 PM * Tom_L goes to finish programming the extinguisher test cap http://tom-itx.no-ip.biz:81/~webpage/rue/extinguisher_cap_path.JPG
01:17 PM CaptHindsight: roycroft: what was the brand of iso paint that you used for machines?
01:17 PM CaptHindsight: it's a 2K (2 part)
01:21 PM roycroft: i'm using a ppg enamel for this machine, that i had them put in some rattle cans for me
01:21 PM roycroft: i don't know the exact product name
01:22 PM roycroft: it doesn't have isocyanates though, so i feel ok using it with my standard respirator
01:24 PM miss0r: ahh. "nice" to feel wanted. Here in Denmark we used to have a rule, where all the kitchen sewage had to be let through a kitchen well, where the fat would float, while the water drains away underneath to the main sewage line. This is no longer a rule - thank god - but us with old houses, still find it clogged right up once in a while when the weather is the coldest. Like just 30 minuts ago.
01:27 PM CaptHindsight: miss0r: we call that a grease trap here
01:27 PM miss0r: makes sense
01:27 PM miss0r: I've often thought about having it removed. But then a few years passes and I forget it exist.. and BOOM backed up again :)
01:29 PM CaptHindsight: does it work like this? https://www.liquidenviro.com/blog-news/grease-trap-vs-grease-interceptor
01:30 PM JT-Shop: Tom_L, I drilled 4mm holes with a 3/16" bit...
01:30 PM miss0r: CaptHindsight: well yeah. except this one is 60 years old and made of concrete
01:31 PM miss0r: and it is single chambered, so theres just some sort of reiser pipe on the outlet. Basically like the two chambers, the one chamber is just a pipe parallel to the well
01:32 PM CaptHindsight: been cold here as well, -15 to -25C
01:32 PM miss0r: damn. that is cold. we only got -13
01:33 PM Tom_L: JT-Shop, woops
01:33 PM miss0r: now that I've gotten the smudge cleaned off the tools, I will get back to working on the lathe :)
01:33 PM CaptHindsight: warm today -8 at 1pm
01:34 PM JT-Shop: yea and used the last bit of that material...
01:38 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Brass_cup/Brass_bar1.jpg
01:38 PM Tom_L: now i gotta figure out how to part off a piece of that bar with no bandsaw
01:43 PM JT-Shop: hacksaw
01:43 PM Tom_L: that's one option
01:43 PM roycroft: karate chop
01:43 PM JT-Shop: borrow someone's chain saw who you don't like
01:44 PM Tom_L: might see what the sawzall does with it
01:46 PM Tom_L: but not just yet. no heat on out there
01:49 PM * JT-Shop finds a piece of 1/4" x 3" and cuts it 3/4" long so I can stagger the two parts from one blank
01:49 PM JT-Shop: orig material was 1/4" x 1 3/4"
02:06 PM * JT-Shop leaves the stock in the band saw as there is enough for one more try at not screwing it up
02:07 PM JT-Shop: soon I'll have to make a trip to McCoys...
03:04 PM -!- #linuxcnc mode set to +v by ChanServ
03:59 PM JT-Shop: geez Louise 3 days to make two little parts...
04:08 PM JT-Shop: I'm glad it's a short month as I'm almost out of data already :(
04:09 PM CaptHindsight: has anyone seen CAM that can deal with a conical cutting tool? Can it understand that as the Z has more depth it cuts a wider path without changing tools?
04:10 PM Tom_L: JT-Shop, you still don't get paid more for them
04:10 PM Tom_L: just because it took 3x as long :)
04:11 PM Tom_L: i wish there was a source for scrap brass around here
04:11 PM Tom_L: they get a few bits from time to time but not that much
04:13 PM JT-Shop: scrap yard doesn't have any brass?
04:13 PM Tom_L: very little
04:14 PM Tom_L: the steel yard i used to go to closed but they didn't have any either\
04:14 PM Tom_L: iirc that aluminum yard was where i got those bits from
04:15 PM W1N9Zr0: CaptHindsight - v-carving? fusion's Engrave op does that, and most engraving CAM packages do it
04:15 PM JT-Shop: next little part will be fun
04:15 PM Tom_L: this for the spoke machine?
04:16 PM JT-Shop: aye
04:17 PM JT-Shop: I can use my scraped parts for the smaller parts
04:47 PM Tom_L: yeah i keep all my cutoffs for smaller parts
05:11 PM skunkworks: Going from a hodge podge wired gb network to fiber home runs is going to be very nice. Farthest run hooked up and working.. 10GB backbone. People noticed.
05:34 PM JT-Cave: nice
05:37 PM CaptHindsight: W1N9Zr0: do you happen to know if they can handle a cone that is inverted ^ vs v so that as the Z moves up from the bed the ^ gets wider vs more narrow?
05:40 PM CaptHindsight: so a V shaped cutting tool with the shank on the pointy side of the V vs the wide side
05:41 PM W1N9Zr0: i doubt there's a market for engraving with dovetail cutters, so probably not
05:44 PM W1N9Zr0: but you could program it with a V-bit and do some post-processor math on gcode to turn it upside-down
05:44 PM CaptHindsight: what I figured
05:45 PM W1N9Zr0: fusion only does it with v-bits, other software can do ball-mills too, so maybe there is some software that supports arbitrary shapes
05:45 PM CaptHindsight: this is with light based tooling vs a hard tool, ^ shaped light beam or liquid spray pattern
05:47 PM CaptHindsight: easy enough with 3 axis on planar surfaces, a but more difficult with 5-axis and non planar surfaces
05:48 PM CaptHindsight: tool close to the surface . , farther away o, even farther O
05:48 PM CaptHindsight: point source of the tool
06:08 PM XXCoder: "Dr. Michael Obeng, who performed the procedure, said all it took was a combination of medical grade adhesive remover, aloe vera, olive oil and acetone to remove it"
06:08 PM XXCoder: that was to clean up lady hair who used gorilla glue to smooth hair
06:08 PM XXCoder: JT-Cave: you dont melt and recast?
06:09 PM XXCoder: i know some parts specs require extrude or forged but..
06:10 PM JT-Cave: melt and recast 6061, no it's not cast it's made through a die
06:10 PM JT-Cave: mic6 is cast aluminum
06:11 PM JT-Cave: I don't think 6061 is castable so to speal
06:11 PM JT-Cave: k
06:21 PM XXCoder: hmm too bad
06:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/extinguisher_nut/Brass_bar3.jpg
06:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/extinguisher_nut/Brass_bar4.jpg
06:27 PM jdh]: that's a pretty clean cut for that file.
06:28 PM Tom_L: it's a damn sharp file
08:42 PM roycroft: oh dear
08:42 PM roycroft: chick corea has passed
08:43 PM XXCoder: huh
08:43 PM XXCoder: oh actor
08:44 PM XXCoder: mostly musician more like
08:53 PM roycroft: he was a great musician
08:54 PM roycroft: i was privileged to see him perform twice in the '70s
08:59 PM XXCoder: nice
08:59 PM XXCoder: i didnt go to much live perforances, but I remember one
09:00 PM XXCoder: chriss angel
09:00 PM XXCoder: (not music but..)
09:00 PM XXCoder: we paid $40 each, which was price for far off corner prices, but got second row because we are deaf
09:00 PM XXCoder: second row is $250 something
09:01 PM XXCoder: and man was it really good
09:02 PM CaptHindsight: yeah it's 2021 and people are still dying
09:02 PM XXCoder: im not sure what your point is
09:04 PM CaptHindsight: 2020 was pretty bad
09:05 PM CaptHindsight: some thing got better this year
09:09 PM CaptHindsight: first image of a coronavirus 1966 https://www.biomerieuxconnection.com/2020/08/27/june-almeida-the-discovery-of-the-first-human-coronavirus/
09:13 PM XXCoder: oh yeah its for us which average 40s I guess that see so many stars in our lives die now
09:20 PM roycroft: three republican senators, who are the jurors in the impeachemnt trial, had a private meeting today with the defense attornies to discuss strategy
09:21 PM XXCoder: yep
09:21 PM roycroft: i can't think of many things that are more wrong than that, yet those senators think it was just fine
09:21 PM XXCoder: interview one of senates (not one who met) said its ethitically doubtious but no law against it
09:21 PM roycroft: no, it's not illegal
09:21 PM roycroft: but it is as wrong as wrong can be
09:22 PM Tom_L: glad you pointed it out here
09:22 PM roycroft: it needs to be pointed out everywhere
09:22 PM roycroft: because so many people would never have heard about it otherwise
09:23 PM roycroft: i won't further belabor the issue - i've said enough already
09:24 PM roycroft: oh, except i need to say one more thing
09:25 PM roycroft: if three democratic senators had met with the house managers to discuss strategy, that would have been just as wrong
09:25 PM roycroft: now i'm done :)
09:27 PM Tom_L: https://www.today.com/food/food-truck-owner-s-relatable-sign-about-masking-goes-viral-t208540
09:28 PM XXCoder: whooo good one
11:11 PM roycroft: i just got an update from the county
11:11 PM roycroft: there are 40,000 unvaccinated people in phase 1a groups 1-4 (currently eligible)
11:12 PM roycroft: the count has 400 vaccines for that group this week
11:12 PM roycroft: county
