12:00 AM Juzzy: (peak)
12:13 AM W1N9Zr0: https://www.geckodrive.com/support/step-motor-basics/motor-power.html
12:18 AM W1N9Zr0: how smooth are your axis? can you move them easily by hand? 4.2A out of 5 shouldn't be too underpowered, 48v is a reasonable voltage for that system too, maybe a bit high since drivers are rated for only 50v
12:21 AM Lcvette: can you guys see me?
12:23 AM W1N9Zr0: yup
12:23 AM Lcvette: awesome, thanks!
12:23 AM XXCoder: nope im not in same room as you
12:28 AM Juzzy: well they used to move easily. once the motors and whatnot are all connected its tougher
12:29 AM Juzzy: not s huge fan of the vbearings + din rail
12:29 AM Juzzy: which is why im leaning towards sbr20's
12:29 AM Juzzy: which is whats on that x axis
12:29 AM Juzzy: and z
12:32 AM W1N9Zr0: are you sure your current switches are configured for 4.2A and not 1.0? (on and off positions switched around)
12:33 AM Juzzy: no, all are off.
12:33 AM Juzzy: 4.20 3.00 OFF OFF OFF
12:34 AM W1N9Zr0: you looked at the label on the switch block to find on/off position right? some of those types of toggles switches are on up, some are on down
12:34 AM Juzzy: I'm actually running OFF OFF OFF
12:35 AM Juzzy: I'm actually running OFF OFF OFF (4.2a) OFF (half power at standby) and OFF ON ON (1600 revs)
12:35 AM Juzzy: which i was debating dropping it from 8 steps to 4 steps, when i tested i was unable to improve anything though
12:38 AM Juzzy: i think my current problem is my gantry is binding after about 15" of travel
12:38 AM Juzzy: happens at like 6-7" out and again at 15" or so
12:38 AM Juzzy: i lose about 1-2" over 17" (450mm) test
12:38 AM Juzzy: does it on the return too
12:39 AM Juzzy: im going to remove the belts tomorrow and play with the resistances
12:40 AM Juzzy: see if i can maybe loosen the bearing bolts to allow for a little more play, maybe i can get them centered and retighten down a little better or something
12:40 AM Juzzy: SBR + screw upgrade is $500, add on 2 new 8-12nM motors and thats $900 upgrade in all :(
12:41 AM Juzzy: bc they need new drivers and new psu
12:41 AM Juzzy: but i would probably repurpose an old X to the bottom of my gantry to get X more juice
12:41 AM Juzzy: erm an old Y motor to X
01:08 AM -!- #linuxcnc mode set to +v by ChanServ
01:39 AM Deejay: moin
02:06 AM Loetmichel: mornin'. Nice, main internet is back. I like that the openWRT uses "whatever is aviable"... so the backup like is now inactive. Boss just deactivated the LTE route and it switched over without a hitch. "i like it when a plan works!" :)
03:07 AM asdfasd: for those who was telling me to forget about LPT port, just found how to achieve jitter less than 3000, most of the time is just above 2000ns haha
03:08 AM XXCoder: unterhaus: forget the replacement for web ui, it dont work properly. i had to restart printer for it to work again after print.
03:08 AM XXCoder: stock one has bug where it doesnt wait for bed to warm up, (and sometimes even hotend!) but easy enough to fix, pre-heat before start next print
03:12 AM rs[m]: asdfasd: what did you do?
03:37 AM asdfasd: I did what some people here told me not to do - wasted few days investigating haha
04:00 AM CaptHindsight: asdfasd: we were talking about you last night
04:00 AM CaptHindsight: we posted a bunch of info in case you read the logs
04:01 AM asdfasd: Im sorry I did see anything more after I left
04:01 AM CaptHindsight: asdfasd: did you set affinity for irq's? or that and/or something else
04:01 AM XXCoder: hence the logs :)
04:01 AM asdfasd: affinity yes, somebody posted some ready scripts, set-irq-affinity
04:02 AM asdfasd: but that was only one of many problems
04:02 AM asdfasd: it seems most CPUs refuse to cooperate
04:04 AM asdfasd: there are many requirements that must be met simultaneously to achieve result, 1 missing and jitter become big
04:06 AM asdfasd: I was replacing motherboards, graphic cards, and nothing worked properly, at the end I did replace the CPU and noticed huge difference
04:06 AM asdfasd: certain CPUs work well, but most dont
04:13 AM asdfasd: how to read the logs?
04:15 AM Tom_L: or
04:16 AM asdfasd: haha
04:16 AM asdfasd: so easy
04:22 AM asdfasd: how close to stable is 2.8 ?
04:23 AM Tom_L: it's been released
04:23 AM asdfasd: The 2.8 branch, currently being stabilized for release
04:25 AM Tom_L: Current release: 2.8.1
04:25 AM Tom_L: http://linuxcnc.org/
04:33 AM asdfasd: yes, its current release, but is it considered as stable or not yet?
05:00 AM JT-Cave: morning
05:00 AM XXCoder: heys
05:13 AM CaptHindsight: asdfasd: stable enough to release
05:14 AM CaptHindsight: asdfasd: usually takes many months to be considered stable before it is released
05:17 AM asdfasd: thanks, I will give it a try
05:32 AM Tom_L: morning
05:42 AM JT-Cave: morning
07:02 AM asdfasd: it seems some packages are available for buster but 2.8 spit some errors when installing
07:03 AM asdfasd: deb http://buildbot.linuxcnc.org/ buster 2.8-rtpreempt
07:03 AM asdfasd: is that correct?
07:03 AM JT-Cave: what's a buster?
07:03 AM * JT-Cave goes to wake up the chickens
07:03 AM asdfasd: debian 10
07:05 AM JT-Cave: I'm running debian 10 here
07:05 AM asdfasd: and which version of linuxcnc?
07:19 AM * JT-Cave is back from cleaning up all the chicken poop
07:19 AM JT-Cave: 2.8
07:20 AM XXCoder: yo yo bathe already ;)
07:20 AM XXCoder: hows eggmakers so far
07:20 AM JT-Cave: https://gnipsel.com/linuxcnc/uspace/debian10-rt.html
07:21 AM JT-Cave: hmm my debian 10 instructions are out of date
07:21 AM gregcnc: 3000 jitter is crazy what hardware?
07:22 AM asdfasd: so if i follow these instructions then linuxcnc should install properly?
07:22 AM JT-Cave: they are doing good, none of the hens are laying at the moment
07:22 AM JT-Cave: asdfasd, let me verify that is the latest info
07:26 AM JT-Cave: I just installed 10 uspace and lcnc 2.8 the other day on a pc
07:27 AM XXCoder: winter thing eh? stopping laying eggs
07:29 AM JT-Cave: some have been sick in the past and don't lay anymore only 2 hens have been laying this winter
07:32 AM asdfasd: JT-Cave: thanks, I will try now
07:34 AM JT-Cave: updating it now
09:45 AM Juzzy: anyone tried this moving knot gantry trick? https://en.industryarena.com/forum/make-your-gantry-rock-solid--51485.html
10:04 AM perry_j1987: Good morning everyone
10:04 AM perry_j1987: wow i really slept in
10:05 AM perry_j1987: that was an accident heh but it sure feels good once in a while
10:05 AM gregcnc: all the worms are gone
10:48 AM perry_j1987: so im looking at different options for collet holding for the new lathe
10:48 AM perry_j1987: i use er32 on my old lathe
10:49 AM perry_j1987: contemplating one of these 5c chucks
10:49 AM perry_j1987: but i also would like to realize an eventual goal of full automation with this thing heh
10:50 AM gregcnc: find one of those I mentioned
10:54 AM perry_j1987: when was this?
10:54 AM gregcnc: front mount lever operated 5C chuck
10:55 AM gregcnc: https://groups.io/g/atlas-craftsman/topic/67744443
10:56 AM perry_j1987: oh ya the lever one
10:56 AM perry_j1987: i had that saved on a tab somewhere
10:57 AM perry_j1987: *ruffling through hundred or so tabs
11:00 AM perry_j1987: found it
11:04 AM perry_j1987: reading up on them someone said they run with bushings instead of bearings and heatup running long term
11:13 AM gregcnc: how many million parts are you running?
11:14 AM gregcnc: those made by Royal use a bearing
11:15 AM perry_j1987: hopefully millions haha
11:16 AM gregcnc: why are you playing with machines if the product is viable?
11:20 AM perry_j1987: im having fun
11:23 AM unterhaus: Somehow I think if you wear out the bushings you'll be able to afford a better closer
11:27 AM perry_j1987: get out of here with *facts lol
12:25 PM unterhaus: There are things I regret not buying 10 years ago, because ebay sellers seem to overvalue everything now
12:25 PM unterhaus: finding a closer for my lathe isn't easy because it's relatively rare
12:25 PM unterhaus: The one that usually shows up for it takes collets I don't have, the rubber ones
12:26 PM unterhaus: good news is if I make one, it has a relatively large opening in the head, so just about anything will fit
12:52 PM gregcnc: unterhaus which lathe?
12:53 PM gregcnc: pretty much nothing is getting cheaper more people are into making or machining
12:57 PM gregcnc: virtually everything that fits in a garage has gone up in price
12:57 PM unterhaus: True
12:57 PM unterhaus: I have a Sheldon R13
12:57 PM unterhaus: It was a toolroom lathe but nobody wanted it because there were better lathes for the price
12:57 PM unterhaus: Pretty awesome lathe though, even though there is significant wear in the ways up near the headstock
12:57 PM unterhaus: it's forward of where I usually have the carriage, so not that significant, just aesthetically horrible
12:57 PM unterhaus: it has the most complex gearbox ever put on a lathe.
12:57 PM unterhaus: and still doesn't do metric without a lot of extra gears
12:57 PM gregcnc: https://www.ebay.com/itm/184629522432
12:59 PM gregcnc: these are good if you can live without the lever
01:08 PM unterhaus: That looks good, the reserve is probably $450
01:09 PM unterhaus: I have been thinking about getting one of the chinese 5c collet chucks. I have a cheap one but I need to true it up
01:10 PM gregcnc: those are slow with the key in the side
01:11 PM gregcnc: https://www.ebay.com/itm/363267257334
01:12 PM gregcnc: if you don't use them often or don't have a lot parts, this can work
01:12 PM gregcnc: these have a cam
01:14 PM gregcnc: https://kalamazooind.com/products/5c-collet-fixtures/1cc-5c-collet-fixture-for-chucks/
01:15 PM unterhaus: That's kinda cool, I have something similar for a different style collet.
01:16 PM unterhaus: much bigger collets than 5c, so a little weird for small things, and I don't have a complete set of collets either
01:16 PM gregcnc: Those sjogern come in larger collets like 2J, so if you have a larger bore, you can make use of it
01:17 PM unterhaus: I feel like if I get a sjogern, I might have to get a backplate too
01:18 PM gregcnc: sure, might not find one with what you need
01:21 PM unterhaus: some days, I don't feel like a particularly good machinist and think I might screw up
01:22 PM unterhaus: Although I watched a youtube of a guy that was no better than me and he trued up a chines 5c chuck just fine, so I should just have faith
01:24 PM gregcnc: some of the precision stuff is about technique you can try things before coming to your finish size to see if its' working
01:32 PM unterhaus: True, and if I ever get my dro working it will make things a lot easier
01:34 PM unterhaus: I have done quite a bit of precision machining, but not on my lathe
01:47 PM perry_j1987: that kalamazoo looks interesting
01:47 PM perry_j1987: looks like can be put on a backplate too not just for holding in bigger chucks?
01:50 PM perry_j1987: yup just called
01:50 PM perry_j1987: that cam action sells it heh
01:50 PM perry_j1987: those other 5c chucks take forever to spin the chuck keys
01:54 PM perry_j1987: likes like machined registration not ground
01:55 PM unterhaus: my guess is rotary ground, but do you see machine marks?
01:55 PM gregcnc: OD is ground
01:56 PM FinboySlick: How can ground be OD if earth be flat?
01:56 PM FinboySlick: (sorry, couldn't help myself)
02:10 PM perry_j1987: ya OD is ground, i was meaning the inside registration surface for if i were to make a backplate for it
02:29 PM perry_j1987: ok heading over to the shop after an extremely long mornin and coffee heh
02:57 PM unterhaus: If the od is ground you can machine a recess. And even grind the mating surface of the recess
02:57 PM unterhaus: the ebay vendor asked for information that wasn't on or in the box, not happy with them now
02:59 PM unterhaus: I am trying to think of where I would have a 2.5/5.5mm dc power connector
03:01 PM unterhaus: psu with 2.1 inner is cheaper on amazon
03:14 PM CaptHindsight: gregcnc: asdfasd started with an intel E5800, then he said he changed cpu's but didn't say to what, he also didn't mention any details about what he did
03:15 PM gregcnc: yeah, would be nice to know
03:15 PM CaptHindsight: irq affinity and other things
03:15 PM CaptHindsight: i5's have been in that range
03:16 PM CaptHindsight: we also don't know how he exercised the system
03:16 PM CaptHindsight: youtubes might bump his latency up
03:17 PM CaptHindsight: I gave him the link to https://forum.linuxcnc.org/18-computer/39371-results-of-latency-test-list-of-computers-tested-for-use-with-linuxcnc so we might know more
03:18 PM eraserhd: Is converting a grbl 3018 to linuxCNC in order to get better gcodes a completely ridiculous thing for a hobbyist software engineer and long-time linux enthusiast?
03:18 PM CaptHindsight: some people run the latency test for 2 minutes without any stress on the system and then go with the results
03:19 PM gregcnc: hopefully he follows up
03:19 PM CaptHindsight: eraserhd: piece of cake
03:20 PM CaptHindsight: eraserhd: you just need to change the controller
03:21 PM eraserhd: So I know smol bit of hobby electronics, definitely anything logic related. I'd need some kind of parallel port logic-level to 24v?
03:21 PM CaptHindsight: eraserhd: GRBL CNC 3018 uses a duino
03:25 PM eraserhd: wait, the existing microcontroller be used? I thought it couldn't. Something something realtime something something.
03:26 PM CaptHindsight: eraserhd: no, LinuxCNC does not run on a duino
03:26 PM CaptHindsight: you have to change the controller to a PC or Rpi
03:27 PM eraserhd: right, I got that part... but how to get parport to drive the steppers and spindle? I have an old junk PC that I'll try (I'll replace if the latency ends up sucking).
03:28 PM CaptHindsight: https://i.pinimg.com/originals/90/f5/b8/90f5b86834e2e12a8ffba0c6aea32968.png
03:28 PM CaptHindsight: does it use this board currentlY
03:28 PM CaptHindsight: eraserhd: ^^
03:29 PM eraserhd: It looks very similar.
03:29 PM CaptHindsight: https://user-images.githubusercontent.com/17933038/73784362-9b559d80-4795-11ea-9ff2-5362aa8671bc.JPG
03:32 PM eraserhd: I'm not at my CNC at the moment, but the layout of the ports is the same, it's definitely AVR-based, it's a different color and from SainSmart.
03:33 PM CaptHindsight: does the PC have a LPT port?
03:33 PM CaptHindsight: there are $10 LPT cards for PCI/e
03:34 PM eraserhd: Not yet, but it will. Or a Mesa card if I fail to be reasonable.
03:34 PM CaptHindsight: LPT ---> BOB (break out board) ---> spindle driver and stepper drivers
03:37 PM CaptHindsight: if the PC has low enough jitter for use with LPT be sure to pick a good vendor for the BOB
03:37 PM CaptHindsight: somebody here just went through a few before getting a good one
03:37 PM CaptHindsight: poor Chinese QC was the problem
03:38 PM CaptHindsight: poo to NO QC
03:40 PM perry_j1987: frozen!
03:40 PM perry_j1987: got caught up talking to neighbor at my building... outside.. far too long lol
03:41 PM FinboySlick: Why control quality when you control the people.
03:41 PM FinboySlick: How goes CaptHindsight?
03:42 PM * eraserhd falls into a hole investigating BOBs. "Nice."
03:43 PM FinboySlick: eraserhd: I think going for a mesa right away is probably worth it.
03:45 PM eraserhd: FinboySlick: heh ok. It was pretty hard to resist, honestly. I could use random extra IO pins in the shop.
03:48 PM FinboySlick: eraserhd: If you were going for a BOB, a 6I25 would do the trick and it's not too expensive.
03:48 PM FinboySlick: I haven't touched my setup in a long time, they can be flashed from linux now, right?
03:57 PM CaptHindsight: FinboySlick: nice to have adults back in charge again :)
03:59 PM FinboySlick: CaptHindsight: Heh, I'll settle for appreciating your newfound optimism.
04:02 PM CaptHindsight: FinboySlick: ?
04:02 PM FinboySlick: You were pretty glum for a while. It's nice to see you perk up a bit.
04:03 PM CaptHindsight: same stuff
04:07 PM CaptHindsight: any further comments in here might enrage the koolaid drinkers
04:16 PM unterhaus: dang, zygo newview for $3700
04:16 PM unterhaus: it's beat though
04:17 PM unterhaus: there is a good one for $3750 https://www.ebay.com/itm/Zygo-NewView-5000-Non-Contact-Surface-Profiler-/293400539830
04:21 PM CaptHindsight: unterhaus: it's 20+ years old
04:21 PM CaptHindsight: all the mm must be old and worn by now
04:21 PM unterhaus: ours is quite old and works really well
04:22 PM unterhaus: only problem is the stitching runs out of memory
04:22 PM unterhaus: I missed the upgrade window though
04:23 PM unterhaus: I imagine that a majority of equipment like that sees very little use and some of it is used a lot
04:23 PM CaptHindsight: can you upgrade the photons?
04:23 PM CaptHindsight: :)
04:23 PM unterhaus: the specs haven't gotten that much better
04:24 PM unterhaus: software is better and you can jostle the machine now, which is a problem with the 5000
04:24 PM CaptHindsight: how do they justify requiring new models?
04:24 PM CaptHindsight: ah ok
04:25 PM unterhaus: I imagine optics have gotten better too, I know microscope objective have
04:26 PM unterhaus: the big thing they could do better for ours is put a nicer camera on it, the imagers are a lot bigger now
04:26 PM unterhaus: but you're talking $5000 maybe
04:27 PM CaptHindsight: image sensors have come a long way in 20 years
04:27 PM unterhaus: yeah, and the 5000 came with one that was out of date when shipped
04:27 PM Tom_itx: do most BOBs adhere to the same DB25 pinout?
04:28 PM unterhaus: I can only answer questions form Tom_L, but yes
04:28 PM Tom_itx: curious where that initial pinout was established? MACH?
04:28 PM CaptHindsight: close except for a couple pins
04:28 PM unterhaus: most of them are what PCW uses on the 25 pin stepper boards
04:29 PM Tom_itx is now known as Tom_L
04:29 PM unterhaus: I think you can reassign pins with mach
04:30 PM unterhaus: steppers outputs are always the same. They switch up on some of the i/o
04:30 PM CaptHindsight: http://www.cncroutersource.com/cnc-breakout-board.html
04:31 PM CaptHindsight: pins 13-18 vary
04:32 PM Tom_L: weren't some pins on the parport not bidirectional initially?
04:32 PM Tom_L: 'control' pins iirc
04:33 PM CaptHindsight: Tom_L: yes, as the port evolved they added more modes
04:33 PM CaptHindsight: but that was all in the 80's- 90's
04:33 PM Tom_L: is that what the EPP is all about?
04:33 PM CaptHindsight: yeah some of that
04:34 PM CaptHindsight: the LCNC wiki has more on the modes
04:34 PM JT-Shop: first covid shot done...
04:35 PM CaptHindsight: http://linuxcnc.org/docs/2.4/html/hal_parallel_port.html
04:36 PM Tom_L: i just never considered using a parport so i didn't look into any of it's options
04:36 PM CaptHindsight: Tom_L: table 1 http://linuxcnc.org/docs/html/hal/parallel-port.html#_pci_port_address
04:37 PM Tom_L: yeah i vaguely recall some of their port address
04:37 PM roycroft: you got yoru first shot, jt-shop?
04:37 PM roycroft: oh, wait
04:37 PM CaptHindsight: I have Mesa and LPT running at the same time
04:37 PM roycroft: you live in a red state
04:38 PM roycroft: so the feds have shipped some to your state
04:38 PM CaptHindsight: roycroft: they are not all crazy :)
04:38 PM roycroft: i'm in a blue state, and they kept saying NO SHOTS FOR YOU!
04:38 PM roycroft: hopefully we'll get some again soon
04:38 PM Tom_L: hardly seems fair
04:39 PM CaptHindsight: Vaccine Tourism in FL
04:39 PM roycroft: without getting into this deeply, it's impossible to say "fair" with anything that the previous regime did while keeping a straight face
04:39 PM JT-Shop: roycroft, yea the national guard and butler county health dept did 2,000 today
04:40 PM CaptHindsight: roycroft: might take a bit to clean up the train wreck
04:40 PM roycroft: we're still fighting to get enough to vaccinate people over 75 in assisted living centers
04:40 PM roycroft: yes, it's going to take a while
04:40 PM JT-Shop: this county was the first in the state to get any
04:41 PM roycroft: and in fairness to the previous regime (it's ok for me to use the word, because i acutally mean it), much of what some attribute to nastiness can actually be explained by incompetence
04:41 PM roycroft: it's funny, though, that florida has gotten way more doses per capita than any blue state
04:42 PM roycroft: the way things are going, i'm looking at mid-april before i'll be able to get my first shot
04:42 PM unterhaus: I think I have 3 parport bobs for no good reason.
04:42 PM roycroft: and just a few days ago our governor said i could get it on 23 january
04:42 PM Tom_L: unterhaus, do they all have analog out?
04:42 PM roycroft: then the very next day she exploded in a press conference about the news from the feds that they would not be sending any more
04:42 PM unterhaus: I think only one
04:43 PM roycroft: she made the promise to us based on a promise from the feds
04:43 PM unterhaus: It's PMDX
04:43 PM roycroft: a promise on which they renegged the very next day
04:43 PM unterhaus: Probably shouldn't have relied on anything coming out of the new administration just yet
04:44 PM Tom_L: wait and see how they change their tune now
04:44 PM unterhaus: can't get worse
04:44 PM JT-Shop: it can always get worse
04:45 PM unterhaus: unlikely in this case
04:46 PM CaptHindsight: the news I've heard recently : 100 million in 100 days, 85% by july
04:46 PM FinboySlick: "There is nothing we can do to change the trajectory of the pandemic in the next several months." is the latest word on the issue so I'd say temper expectations.
04:46 PM roycroft: time will tell
04:46 PM roycroft: my current expectation is that *IF* people start behaving responsibly, the pandemic may be over by the end of the year
04:47 PM roycroft: with still a significant number of cases over the next several years
04:47 PM roycroft: there are virtually no cases on the african continent at all right now
04:47 PM FinboySlick: roycroft: On that front it's not so bad. I was just reading that 80% of americans already wear masks in public.
04:47 PM roycroft: that's expected to change soon, with northern africa starting to see some outbreaks this spring and sub-saharan africa by next year
04:47 PM CaptHindsight: we look like Asians here now, masks have been common since the early 00's
04:47 PM roycroft: 80% is not nearly enough
04:47 PM roycroft: we need 100%
04:48 PM roycroft: especially since the ones who refuse to mask are the same ones who engage in other behaviors that make them much more susceptable to contracting the virus
04:48 PM roycroft: and btw
04:49 PM roycroft: those 15,000 national guard troops who were deployed to protect the capitol a couple weeks ago were all tested before going there
04:49 PM roycroft: they get tested regularly
04:49 PM roycroft: hundreds of them now test positive
04:50 PM FinboySlick: Well, I wasn't suggesting that it's enough. It's just a lot more than I expected.
04:50 PM unterhaus: the kid that checked me out at the grocery had the sniffles. I was glad we had masks on, even thouogh sniffles aren't a symptom of covid
04:51 PM XXCoder: hey all
04:52 PM roycroft: fedex showed up here two days ago with a parcel that had to be handed off in person - signature release was not allowed
04:52 PM CaptHindsight: was at the ER last night, was allowed to stay as a visitor and just had to wear a mask
04:52 PM roycroft: the guy knocked on my door
04:52 PM roycroft: i answered it, masked
04:53 PM roycroft: he was standing right at the door - his nose must have been pressing aginst it before i opened it, and he was unmasked
04:53 PM CaptHindsight: was pretty quiet bu they are all set to handle overflow with beds in all the hallways
04:53 PM roycroft: i've received two phone calls from federal express supervisors since then asking me for details
04:53 PM roycroft: they seem to be taking this very seriously
04:53 PM CaptHindsight: roycroft: is he recovering from your beating? :)
04:53 PM roycroft: i did not say a word to him about it
04:54 PM roycroft: my goal was to get him to go away as quickly as possible
04:54 PM roycroft: and then i immediately called fedex
04:54 PM XXCoder: jeez
04:54 PM CaptHindsight: yeah they should know better
04:54 PM roycroft: they do
04:54 PM roycroft: they get reminded every single day before they go out on their route
04:57 PM XXCoder: unterhaus: any luck so far?
04:57 PM CaptHindsight: i drove past the bars around here the other day, filled with 20-somethings , no masks, side by side at the bar
04:57 PM unterhaus: they asked me for 2 things that they didn't send me
04:57 PM roycroft: that driver has been working for them for years and years
04:58 PM CaptHindsight: open against state orders
04:58 PM roycroft: i don't like to make assumptions, but i'm assuming he's of the same ilk as the insurrectionists
04:58 PM roycroft: perhaps not as radical, but with the same basic beliefs
04:58 PM unterhaus: XXCoder, a green hu man IT ty barcode and a serial number, which the machine doesn't have
04:59 PM roycroft: either that or he's just really really stupid in some other way
04:59 PM XXCoder: mine has barcode under bed
04:59 PM XXCoder: piush it forward fully and you might see it
04:59 PM unterhaus: okay, that's a weird place for it
05:00 PM XXCoder: yeah
05:00 PM XXCoder: might want to get phone with camera to take picture of it for easier reading
05:01 PM CaptHindsight: i don't have gutters, should I be worried that they will get clogged? I don't like climbing ladders either
05:01 PM JT-Shop: had a guy call me with questions about a 7i96, turns out he didn't even buy it from me... next he wanted me to ssh into his pc to diagnose a problem lol
05:02 PM XXCoder: jeez free tech support guy. that guy.
05:02 PM XXCoder: capt huh
05:02 PM CaptHindsight: XXCoder: incessant gutter guard commercials
05:02 PM XXCoder: oh lol
05:03 PM JT-Shop: hmm replacement stepper cable will be here monday... that was an interesting thing to diagnose
05:03 PM CaptHindsight: JT-Shop: was that why the stepper was running backwards?
05:03 PM perry_j1987: hey guys, these quickchange tool posts... i assume the dove tails should be perfectly 90 degrees to eachother no? :P
05:04 PM Tom_L: JT-Shop, ssh in and dd
05:04 PM JT-Shop: two wires were crossed up at the plug
05:04 PM CaptHindsight: perry_j1987: would definitely help
05:04 PM JT-Shop: Tom_L, I too tired to even do that lol
05:05 PM JT-Shop: CaptHindsight, yes
05:05 PM JT-Shop: B+ and B- were swapped
05:05 PM perry_j1987: i indicated in the face of my #1 tool holder its deadon
05:05 PM perry_j1987: put drill chuck holder on the other face thats inline with the spindle
05:05 PM perry_j1987: and its very off
05:09 PM roycroft: and i'm off to the steel yard
05:09 PM JT-Cave: my youngest daughter got her second shot yesterday
05:17 PM gregcnc: capthindsight, IL is opening back up real quick here
05:18 PM XXCoder: jt awesome :)
05:20 PM unterhaus: ssh in and rm -rf
05:20 PM unterhaus: I ssee the problem now
05:20 PM CaptHindsight: gregcnc: is that the local news? i haven't heard
05:21 PM unterhaus: XXCoder, no stickers there either
05:21 PM XXCoder: looked on main body? not on bed
05:21 PM gregcnc: chicago schools opened this week or last? school sports are back on,
05:21 PM unterhaus: yeah. pretty much looked the whole thing over, haven't disassembled anything yet
05:22 PM XXCoder: no disassembly needed
05:22 PM unterhaus: they really screwed this one up
05:22 PM JT-Cave: XXCoder, she is a nurse near Houston
05:23 PM unterhaus: JT-Cave, did she hold out for the $500 bonus?
05:23 PM XXCoder: jt yeah i think i remember you menioning that :)
05:23 PM gregcnc: how many coworkers aren't taking it?
05:24 PM JT-Cave: what $500 bonus?
05:24 PM unterhaus: there is a hospital system in Houston that is giving people $500 to take the vaccine
05:24 PM unterhaus: because their percentages were so low
05:25 PM JT-Cave: she is north of Houston
05:25 PM JT-Cave: geez you would think people working in a hospital would be first in line to get it
05:26 PM unterhaus: I would pay, tbh
05:26 PM XXCoder: https://i.imgur.com/sNpO4xX.png
05:26 PM XXCoder: thats where mine is
05:27 PM XXCoder: maybe yours is on front not back like mine
05:56 PM roycroft: that's stupid
05:56 PM roycroft: you don't pay people $500 to behave properly
05:57 PM roycroft: you tell them to stay home without pay until they get the vaccine
05:57 PM JT-Cave: all the grocery stores here send there employees to get their shots on the clock
05:57 PM roycroft: the market that i go to tests all employees at the beginning of their shift
05:58 PM roycroft: and the employees must wear a sticker with their picture on it and the time and date of their most recent test
05:58 PM roycroft: we're not at the point where grocery workers are eligible to get the vaccine yet
05:58 PM JT-Cave: test with the rapid antibody test?
05:58 PM roycroft: we're still working on those seniors in assisted living centers who are over 75
05:59 PM roycroft: and first responders
05:59 PM roycroft: then comes teachers
05:59 PM roycroft: because we need to reopen our schools
05:59 PM roycroft: i'm not sure what test they're using
05:59 PM roycroft: nor if they get instant results
05:59 PM JT-Cave: my sister is teaching via some kind of internet thing they came up with
05:59 PM roycroft: but even if it takes a day to get results, getting tested very day is a big step forward
05:59 PM roycroft: we've been doing remote learning in oregon for almost a year
06:00 PM roycroft: but that's not good enough
06:00 PM roycroft: we really need to get the student back in the classroom
06:00 PM roycroft: students
06:00 PM roycroft: what we need is for this whole thing to be over
06:00 PM JT-Cave: you gotta do what you can if you can't have the ideal
06:00 PM roycroft: which is why people need to learn how to behave properly
06:00 PM JT-Cave: yea that won't be anytime soon
06:01 PM roycroft: yes, and the longer the anti-maskers are allowed to roam freely, the longer before the pandemic is over
06:01 PM XXCoder: yeah. i still remember that "i cant get haircut" guy
06:01 PM XXCoder: heez
06:01 PM JT-Cave: don't hold your breath waiting for idiots to start doing sensible things
06:01 PM roycroft: may be president biden should build a wall around florida and deport the anti-maskers to florida :)
06:02 PM roycroft: and offer amnesty to masked floridians seeking asylum
06:02 PM JT-Cave: send them to Mexico, no need to build anythign
06:02 PM roycroft: why?
06:02 PM roycroft: we don't hate mexico :)
06:02 PM JT-Cave: I'm sure they would deal with them quickly
06:03 PM roycroft: anyway, congrats on getting your first poke
06:03 PM JT-Cave: can't wait for the second one
06:03 PM roycroft: please wait 21 or 28 days, depending on which one you got :)
06:04 PM roycroft: but actually, you'll see about 50% immunity in a couple weeks from just the first one
06:04 PM XXCoder: yeah though keep using masks, as can still spread even when immune
06:05 PM roycroft: and recent studies have shown that if you can't get the second one as soon as it's time, because of scheduling/availability, you can go at least up to 45 days to get the second one with the same efficacy as if you got it sooner
06:05 PM roycroft: so if you can't get it on the day it's due, don't worry about it
06:05 PM roycroft: we're not sure about that, xxcoder
06:05 PM roycroft: but being not sure is enough reason to continue to mask
06:06 PM roycroft: there are mixed results from studies on shedding the virus after being vaccinated or having had covid-19
06:06 PM XXCoder: i remember reading about person can be still slightly infected before immune system responds
06:06 PM XXCoder: shredding virus how?
06:06 PM roycroft: until we reach herd immunity we're all going to have to keep masking and distancing
06:07 PM roycroft: by breathing
06:07 PM roycroft: hence the reason to continue masking
06:07 PM XXCoder: no, i mean vaccine dont have whole viruses at all
06:07 PM roycroft: right
06:07 PM roycroft: well the current ones are not viral - they're mrna
06:07 PM roycroft: some of the ones coming up are actually viruses, but not sars-cov-2
06:08 PM roycroft: they're different viruses that are modified to produce the spike protein that sars-cov-2 makes
06:08 PM roycroft: and one of the chinese viruses is actually a weakened sars-cov-2 virus
06:08 PM roycroft: we won't see that one in the us, i think
06:09 PM CaptHindsight: XXCoder: even when immune your immune system takes a little bit of time to respond, during that period you can shed the virus, you are correct
06:09 PM roycroft: yes, when you first contract the virus you can shed it while your immune system is starting to attack it
06:09 PM XXCoder: yeah
06:09 PM XXCoder: ah yeah thats what you mean roy :)
06:09 PM roycroft: yes
06:09 PM CaptHindsight: there is also the period between receiving an immunization and becoming immune
06:10 PM XXCoder: i thought you mean just start shredding virus by vaccine lol
06:10 PM roycroft: oh, that cannot happen
06:10 PM XXCoder: indeed
06:10 PM roycroft: what jt got was not anything resembling a virus
06:10 PM roycroft: it was a little strand of rna wrapped in a nanolipid packet
06:11 PM JT-Cave: I got the Pfizer
06:11 PM roycroft: yup
06:11 PM CaptHindsight: mRNA vaccines do NOT alter your DNA https://imgur.com/gallery/GZDisBs
06:11 PM roycroft: and what i just described is what both the pfeizer and moderna vaccines are
06:12 PM roycroft: btw, as a bit of trivia, a lot of folks think that the name moderna is a take on "modern"
06:12 PM roycroft: it's really describing what they do - it's a take on "modified rna"
06:13 PM roycroft: i picked up some um plate today, so i should probably get out to the shop - i need to fabricate the motor mount for my new bandsaw stand
06:14 PM JT-Cave: go get that thing back in service so we can see a photo of it
06:14 PM * JT-Cave has to focus on automating that second spoke lathe starting Monday
06:14 PM roycroft: it will be a little while yet
06:15 PM roycroft: but i'm making steady progress
06:15 PM roycroft: i just ordered a new fence for the saw, which will arrive next week
06:15 PM JT-Cave: anything good is worth waiting for
06:15 PM roycroft: i figured since i'm not going to spend $2k on a new saw, i can spend ~$500 for the stand, motor upgrade, and fence for the current one, and still be $1500 ahead
06:16 PM JT-Cave: and end up with a better saw
06:16 PM roycroft: yes
06:16 PM roycroft: it will work better
06:16 PM roycroft: and it will be a lot safer - i got a magnetic switch for it
06:16 PM roycroft: i hate stationary tools that don't have mag switches
06:16 PM JT-Cave: I remember
06:16 PM roycroft: it's just scary
06:17 PM roycroft: also, i'm going to mount the switch up at chest level
06:17 PM roycroft: on the current stand the switch is way down at the bottom, and i have to bend down to reach it
06:17 PM roycroft: also scary
06:18 PM JT-Cave: I like the switch location on the SawStop I can reach it with my knee
06:18 PM JT-Cave: it is the best switch in my shop for turning a machine off
06:20 PM roycroft: yes, that's the perfect place to locate a power switch, at least on any tool that requires both hands to operate
06:20 PM JT-Cave: a bit of triva the first table saws had detect contact with skin
06:20 PM roycroft: my table saw switch is at knee level, but inset under the table
06:20 PM roycroft: i need to relocate it when i get a chance
06:21 PM JT-Cave: after a while it became normal to turn the saw off with my left knee
06:22 PM unterhaus: XXCoder, maybe that's it, it's on the back under the bed
06:22 PM XXCoder: yay! :) hope they will send you power brick soon then
06:22 PM roycroft: my plan is to pull the switch out closer to the front of the saw, and then hinge a big paddle in front of it that will press on the off button
06:23 PM roycroft: so i don't even really have to aim to turn it off
06:23 PM JT-Cave: good plan
06:23 PM roycroft: just move my knee in the general direction of the saw
06:23 PM XXCoder: so far my prints is amazing, and im now daring to do very big print now. 12 hours. lincoln seated statue scan
06:23 PM roycroft: anyway, i should get started on this motor mount
06:23 PM roycroft: it's kind of overkill - i got 3/8" um for it
06:24 PM JT-Cave: oh yea it is a Barnes treadle saw
06:24 PM roycroft: but i need some 3/8"x8" plate for another project, so i figure i'd just buy a long piece of it and have a very sturdy motor mount
06:26 PM JT-Cave: 3/8" hot roll plate?
06:46 PM perry_j1987: hmm how do you install pip on linuxcnc distro
06:46 PM perry_j1987: wheezy
06:46 PM perry_j1987: unable to locate package
06:46 PM JT-Cave: google how do I install pip or pip3
06:47 PM perry_j1987: thats not the issue
06:47 PM perry_j1987: the repos are just not there on linuxcnc wheezy distro
06:47 PM JT-Cave: what is the?
06:47 PM Tom_L: was wheezy pre pip?
06:47 PM perry_j1987: how do you install pip on linuxcnc wheezy
06:48 PM JT-Cave: google it
06:48 PM Tom_L: https://unix.stackexchange.com/questions/182308/install-python-pip-in-debian-wheezy
06:48 PM JT-Cave: pip has been around for a long timne
06:48 PM Tom_L: naw i did it for him
06:48 PM JT-Cave: lol
06:48 PM Tom_L: lazy bastard
06:48 PM JT-Cave: I'm too tired to do it for him
06:49 PM Tom_L: why do you need pip anyway?
06:49 PM JT-Cave: see you in the morning
06:49 PM Tom_L: bright and early
06:49 PM JT-Cave: cause some stuff is not in the debian repositories
06:49 PM JT-Cave: yup
06:49 PM XXCoder: later jt
06:50 PM Tom_L: although i might sleep in, been a hectic week
06:52 PM XXCoder: man I love Thomas Johnson Antique Furniture Restoration channel for some reason
07:12 PM roycroft: i don't know of that channel
07:12 PM roycroft: i assume you're talking about a youtube channel
07:12 PM roycroft: pip?
07:12 PM Tom_L: a package installer
07:12 PM roycroft: that's the old file copy command from cp/m
07:12 PM roycroft: pip dest source
07:18 PM XXCoder: roy yeah its restoration channel. its not one of those bullshit restore sites
07:18 PM XXCoder: he restores many stuff, and sometimes its hundreds years old stuff
07:18 PM XXCoder: all stuff wood, not electrics etc
07:19 PM XXCoder: one im watching is one about 17th centry stool
07:19 PM XXCoder: https://youtu.be/U3wAQzjlj54
07:20 PM XXCoder: hm he says its 17th, but video info says 18th. lol ok
07:21 PM roycroft: i'll check out his channel when i get a chance and let you know if he's real or not :)
07:22 PM roycroft: oh, he's from maine, so there's already a chance he knows his stuff
07:31 PM roycroft: so far he seems to know his stuff
07:31 PM roycroft: he's using liquid hide glue, though, which is not as strong as the stuff you have to heat up
07:31 PM XXCoder: yeah. suggest watch some more videos, including restoring some congress chairs thats 300 years old
07:32 PM roycroft: the glue joints wil probably only last a couple hundred years instead of 300+ years :)
07:32 PM roycroft: old brown is the best of the liquid hide glues on the market
07:32 PM XXCoder: i suspect hes also looking into future
07:32 PM XXCoder: keeping them restorable in future
07:32 PM roycroft: well that's the case with all hide glue
07:32 PM XXCoder: rather than more eprment fix that cannot be restored
07:32 PM roycroft: and that's what i was looking for when i started watching the video
07:33 PM roycroft: if he pull out some yellow glue or epoxy i'd have turned it off immediately
08:35 PM roycroft: i'll have to watch some more of that guy's videos, xxcoder, but based on the one that you linked he seems to know his stuff
08:35 PM XXCoder: yeah :)
09:36 PM Tom_L: roycroft, you referring to that animal glue you heat in a pot of water?
09:37 PM Tom_L: https://upload.wikimedia.org/wikipedia/commons/f/f1/Knochenleim_Granulat.jpg
09:44 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20210122_212704.jpg
09:45 PM XXCoder: is that umm whats that thing called again?
09:45 PM XXCoder: homostatic gear something?
09:45 PM skunkworks: 100 to 1
09:45 PM skunkworks: harmonic
09:45 PM XXCoder: ah yes
09:45 PM Tom_L: printed?
09:45 PM skunkworks: yes
09:46 PM skunkworks: feels good
09:46 PM XXCoder: nice
09:46 PM XXCoder: https://imgur.com/a/Eau1C0B been printing stuff heh
09:46 PM XXCoder: now printing abe lincoln seated statue
09:46 PM XXCoder: not done anytime soon lol
09:47 PM skunkworks: I have a mini too!
09:47 PM Tom_L: skunkworks, did you do the cad model yourself?
09:47 PM skunkworks: and an ender 3 now.. Like it
09:47 PM skunkworks: yes
09:47 PM skunkworks: Tom_L: yes
09:48 PM skunkworks: autocad 12 for the tooth profile -> imported into freecad to make the model.
09:48 PM skunkworks: because that is how I roll
09:48 PM Tom_L: wondered what tooth profile you used
09:48 PM skunkworks: It is just a triangle - 50deg
09:48 PM XXCoder: skunk its VERY nice printer
09:48 PM skunkworks: (it doesn't need to be fancy involute)
09:48 PM XXCoder: got it for 77 usd, shipped
09:49 PM Tom_L: sure it does :)
09:49 PM skunkworks: I don't remember what I paid for mine - it was pretty new at the time - probably close to 200 (V2)
09:49 PM XXCoder: org price 216 i think
09:49 PM Tom_L: i stopped on my gear macro, having issues joining the 2 endpoints when i array the gear
09:50 PM Tom_L: they're very close but don't quite touch
09:51 PM skunkworks: It took a bit of thought to get the tooth array to work. (the reason why I did it in autocad is there wasn't a polar array in sketch in freecad)
09:51 PM skunkworks: I probably should have made 1 tooth a solid model - then arrayed that.
09:51 PM skunkworks: still learning
09:52 PM skunkworks: filleting the 200 teeth takes a bit - when you draw it this way
09:52 PM skunkworks: :)
10:03 PM skunkworks: the inside and outside need to be the same pitch - just 2 or whatever less teeth
10:08 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Gear_info/gear.jpg
10:08 PM skunkworks: http://electronicsam.com/images/greenmachine/Screenshot_2021-01-22_21-54-45.png
10:08 PM Tom_L: i just threw some random numbers at it
10:09 PM skunkworks: cool
10:10 PM Tom_L: the root diameter would need trimmed at each tooth
10:12 PM Tom_L: i did one for sprockets too
10:29 PM roycroft: for sprockets?
10:29 PM roycroft: did you get to meet dieter?
10:30 PM roycroft: did you touch his monkey?
10:31 PM skunkworks: Tom_L: is that some sort of lisp?
10:31 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/GEAR1.MCL
10:31 PM Tom_L: my threadmill one is there too
10:32 PM skunkworks: does anyone remember dc cad?
10:32 PM Tom_L: dancad?
10:32 PM Tom_L: no
10:32 PM skunkworks: no.. I think it was design cad
10:33 PM Tom_L: acad has a lisp language doesn't it?
10:33 PM skunkworks: yes
10:33 PM roycroft: acad has a lisp engine
10:33 PM Tom_L: i looked at it many years ago but never did much with it
11:11 PM roycroft: so the pfizer five dose vaccine vials are being shipped with enough of the vaccine for six doses, if the correct type of syringe is used
11:11 PM roycroft: pfizer asked the feds if they could count each vial as six doses instead of five
11:11 PM roycroft: last week the fda agreed
11:12 PM roycroft: the vaccines ship from the feds with syringes
11:12 PM roycroft: the feds do not have the low dead space syringes that let one get six doses out of a vial
11:12 PM roycroft: there is shortage of those syringes
11:12 PM roycroft: so pfizer get to ship less vaccine to the us for the same price as they were getting before
11:13 PM roycroft: and we get less
11:13 PM Tom_L: welcome to merica
11:15 PM Tom_L: by the time i can get it, i likely won't need it
11:15 PM roycroft: i hope the fda is run by scientists again soon
11:16 PM Tom_L: i'm not holding my breath
11:16 PM roycroft: there will be a lot of changes
11:17 PM roycroft: but a lot of damage has been done over the last four years, and it's going to take time to fix things
11:17 PM roycroft: but i'm pretty confident that dealing with the pandemic is the top priority and the thing that will improve the most visibly in the near term
11:28 PM roycroft: wow
11:28 PM roycroft: monday's forecast calls for snow in the morning and thunderstorms in the afternoon
