04:57 AM jthornton: morning
05:02 AM XXCoder: hey
05:02 AM Tom_L: morning
05:02 AM Tom_L: somebody's been working on the docs... html man pages lost their columns
05:06 AM jthornton: I saw some commits from someone "fixing" the docs for some reason
05:14 AM Tom_L: XXCoder, in washington?
05:14 AM XXCoder: usa
05:14 AM XXCoder: wa alone is over 100
05:15 AM BitEvil is now known as SpeedEvil
05:15 AM Tom_L: jthornton, i wonder if the guy doing the chinese version may have had a part in that
05:16 AM Deejay: moin
05:18 AM jthornton: which page are you looking at
06:04 AM jymmmm: morning
07:19 AM Tom_L: jthornton, http://linuxcnc.org/docs/2.7/html/ , http://linuxcnc.org/docs/2.8/html/ and http://linuxcnc.org/docs/devel/html/
07:19 AM Tom_L: it would be in the formatting file
07:20 AM jthornton: they all look normal to me
07:21 AM Tom_L: from the Man Pages down used to be in multiple columns
07:21 AM Tom_L: now on ff at least they're a single column down the left side
07:22 AM jthornton: they are still in 4 columns for me
07:22 AM Tom_L: even after a refresh, no
07:22 AM jthornton: if I expand the page I get 9 columns
07:23 AM Tom_L: odd
07:23 AM Tom_L: i tried that before i mentioned it...
07:24 AM Tom_L: same on the other pc
07:24 AM jthornton: it's been years since anyone touched the html formatting
07:25 AM Tom_L: i figured
07:25 AM Tom_L: dunno what's goin on
07:25 AM jthornton: someone touched the index.tmpl 22 days ago
07:27 AM jthornton: chris morley added something 22 days ago
07:27 AM Tom_L: not a biggie, just surprised me
07:27 AM Tom_L: gotta run...
08:21 AM thesaint4444: hi, can anyone tell me what is the current computer hardware to buy for linuxcnc? thanks..
08:26 AM Loetmichel: thesaint4444: anything that has at least 2 cores @3ghz and preferably with an LPT port or a PCI slot to put one in.
08:27 AM Loetmichel: or if you want to use MESA: a fitting slot for your mesa card
08:27 AM thesaint4444: amd or intel? no difference?
08:27 AM Loetmichel: it doesent need THAT much computing power
08:27 AM thesaint4444: that depends on what you are doing.
08:28 AM Loetmichel: ah, preferably with a dedicated GPU, no internal graphics
08:28 AM thesaint4444: an external graphics card?
08:28 AM Loetmichel: more to the point: If you want to do LPT drive you have to have a board that has no NMI "power save" routines
08:29 AM Loetmichel: thats why they always say "no notebooks"
08:29 AM thesaint4444: i use a mesa card..
08:29 AM Loetmichel: no, external as "in a PCIE-slot, not in the CPU"
08:30 AM Loetmichel: if you have a mesa card then pretty much the only thing you have to look out for is a fitting slot in the mainboard
08:30 AM thesaint4444: so any modern mini pc board just about?
08:30 AM Loetmichel: or if its a RJ45-one: a dedicatet gbit NIC for the card
08:30 AM thesaint4444: with a pci slot..
08:31 AM thesaint4444: thanks!
08:31 AM Loetmichel: so your mesa card has a PCI interface?
08:31 AM Loetmichel: then yes
08:31 AM thesaint4444: yes, i think..
08:32 AM Loetmichel: anything thats 2 cores and up at 3ghz at least should work fine
08:32 AM thesaint4444: great, cheers!
08:32 AM Loetmichel: hell, there are people that have gotten LinuxCNC to run on a raspberry pi3
08:32 AM Loetmichel: :-)
08:33 AM Loetmichel: (dont know how though, that thing is a bit low on the computing power side)
09:53 AM Loetmichel: GNAH! New worker on the CNC mills since friday... took him 2 days and the 20 2mm tungsten carbide 2flute mill bits i had in stock are gone... *sigh* *reorder another 30*
09:54 AM gregcnc: no guidance? or does he know everything?
09:55 AM skunkworks: heh.. Ouch
09:56 AM Loetmichel: gregcnc: more like: to dumb to learn from errors
09:56 AM Loetmichel: i showed him how to change the mill bit. my bad.
09:56 AM gregcnc: so you hired a tool changer
09:57 AM Loetmichel: kinda ;)
09:57 AM gregcnc: looks like you'll need to spend some time teaching
09:59 AM SpeedEvil: Loetmichel: At some point, HSS might last longer
10:02 AM pcw_home: RPI3 does work (had a demo running LinuxCNC for about a year) but graphics are slow and dense backplots would cause a crash (out of memory) RPI4 (with 2G or 4G RAM) is _much_ better
10:05 AM Loetmichel: SpeedEvil: probably
10:06 AM Loetmichel: or a worker that removes any swarf from the part before before he puts a new alu sheet on teh vacuum table ,)
10:11 AM skunkworks: Yes - the rpi4 is very usable. I have been testing it for a while now.
10:12 AM gregcnc: if I know nothing about rpi how hard is it to setup, is googlefu enough?
10:12 AM sensille: linuxfu is helpful
10:12 AM Loetmichel: SpeedEvil: i suspect thats why he breaks the bits. bump in the sheet metal from swarf under it... and i am close to the max "material removal" capacitiy of the CNC 6040 already with my program
10:13 AM Loetmichel: so when there is a bump it cuts to deep into the materal and breaks the bit off
10:13 AM rmu|w: gregcnc: if you manage to install linuxcnc from github on a pc you will manage on a rpi4
10:13 AM gregcnc: ok.
10:14 AM skunkworks: This was done on the pi.. https://www.youtube.com/watch?v=c9tWtEG1Exc
10:14 AM rmu|w: the only "interesting" thing probably is how and where to get a preempt-rt enabled kernel
10:14 AM skunkworks: gregcnc: there is a image with linuxcnc and everything.
10:15 AM skunkworks: hmm - where is it
10:17 AM skunkworks: https://zaphod.unpythonic.net/pi/
10:19 AM gregcnc: great! do you have a page documenting what you've done in your videos?
10:28 AM skunkworks: eh.. not really.. https://forum.linuxcnc.org/10-advanced-configuration/38549-non-circular-boring-linuxcnc-fun
10:45 AM rmu|w: https://www.osadl.org/Profile-of-system-in-rack-7-slot-2.qa-profile-r7s2.0.html?shadow=1
12:02 PM fragalot: 'sup
12:19 PM JT-Shop: I think I've gotten an email from every supplier I've ever dealt with about covid 19 and they are fully stocked and shipping product
12:42 PM pcw_home: We cant get parts anymore...
12:44 PM pcw_home: Fedex: no shipments to non-essential businesses (we might get a DOD exemption though)
12:44 PM pcw_home: not sure If I want to pursue that or not
12:48 PM * SpeedEvil is hoping for one or two last deliveries before UK shuts down.
12:49 PM SpeedEvil: there may be a van in my driveway soon with 100 bits of wood.
12:49 PM SpeedEvil: (CNC related - I'm sort of thinking about making a concrete printer with it.)
12:56 PM Loetmichel: JT-Shop: same here... and then you have to drive around for half an hour to find a home improvement shop that is still open to get some OSB for a overseas box ;)
12:58 PM Spida: delivery services like UPS/Fedex/DHL are a bit slower than usual (2 or 3 instead of 1 day). apart from that, no limitations except toiletpaper, pasta and canned food.
01:11 PM Rab: pcw_home, are you able to ship (current inventory) product out?
01:18 PM pcw_home: we did on Friday not sure today, maybe USPS only
01:26 PM jymmmm: YAY no power (on gen)
01:27 PM jymmmm: SO, shelter in place, no power, it's gonna rain/snow, are we camping yet?
02:17 PM JT-Shop: I'm trying to decide if I'll ship anything the next two weeks...
02:18 PM JT-Shop: if it's under 8.5 oz I can just put it in the mail box and put the flag up...
02:20 PM JT-Shop: hmm 13 ounces with postage only can't be picked up
02:22 PM andypugh: skunkworks: https://hackaday.com/2020/03/23/a-boring-tale-with-six-sides/#more-404387
02:29 PM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/cnc-parts/cnc-router-rotational-axis-the-4th-axis/ how bad are these? anyone actually try one?
02:30 PM CaptHindsight: likely better off just making one vs taking these apart and replacing the bearings and getting them square
02:34 PM andypugh: I would be more concerned about a lack of holding torque. I can only reallt see them working for engraving, but I could be wrong.
02:35 PM CaptHindsight: pulley ratio 1:6
02:37 PM CaptHindsight: 3A 57type is likely nema23
02:37 PM Loetmichel: CaptHindsight: i have one with a worm drive and one with a pulley
02:37 PM andypugh: So, 6:1 with a (maybe) 3Nm stepper is 18Nm torque. Doesn’t sound like a lot.
02:37 PM Loetmichel: the worm drive is worse because it has close to 1° in play
02:38 PM Loetmichel: the belt drive one is much better
02:38 PM CaptHindsight: 1 deg play :)
02:38 PM Loetmichel: needs light cuts so you dont overpower the stepper holding torque but at least it doesent wobble all over the place
02:38 PM roycroft: we just got semi sheltered in place
02:39 PM CaptHindsight: andypugh: cutting plastic <1mm
02:39 PM CaptHindsight: roycroft: welcome to shelter in place
02:41 PM CaptHindsight: oh they are carrying the cheap ballscrew positioners now https://www.automationtechnologiesinc.com/products-page/ballscrew-supports/ballscrewlinearguideway/
02:41 PM Loetmichel: CaptHindsight: the worm drive one works for certain things
02:42 PM Loetmichel: bit its no good for engraving for example
02:42 PM Loetmichel: pretty good for "turning" on the mill though
02:42 PM Loetmichel: https://www.youtube.com/watch?v=yDcCyF_gVoY
02:42 PM CaptHindsight: Loetmichel: I knew they weren't made well for <$300
02:43 PM Loetmichel: so my advice would be: get the belt drive one and just use it with light cuts
02:44 PM CaptHindsight: Loetmichel: is that the belt drive version?
02:44 PM Loetmichel: thats the worm drive one
02:44 PM Loetmichel: have no pics on the belt drive one, its also with a MUCH smaller 3jaw
02:45 PM CaptHindsight: $4k used https://www.ebay.com/itm/Pocket-NC-5-Axis-Mill-with-new-spindle-and-web-interface-slightly-new/124114972902
02:49 PM Loetmichel: IMHO that 5 axis toy is not worth the money
02:49 PM Loetmichel: depends on what you want to do with it though
02:49 PM CaptHindsight: Loetmichel: the application is <1mm plastic
02:49 PM Loetmichel: then it should work
02:49 PM Loetmichel: still overpriced for the travel it has ;)
02:50 PM andypugh: I think PocketNC is cool. And it runs LinuxCNC.
02:50 PM CaptHindsight: $3k https://www.ebay.com/itm/Steel-Structure-CNC-3040-5axis-2-2KW-Metal-Router-Engraving-Milling-DIY-Machine/202943768725
02:51 PM CaptHindsight: $5500 new
02:52 PM XXCoder: "slightly new" is different from "slightly used" ;)
02:52 PM CaptHindsight: fun with words
02:53 PM XXCoder: that pocket nc seems to be missing panels?
02:53 PM CaptHindsight: if I make enough of them I should cast a frame
02:54 PM CaptHindsight: $36K https://youtu.be/ZLDR0aJAYIA?t=19
02:55 PM XXCoder: i wonder why theres so many haas on ebay
02:56 PM JesseG: A real life friend of mine is friends with Gene Haas - they were like buddies in college or something :P I never met Gene though.
02:56 PM XXCoder: ugh. searched for haas, all results is bunch of NOT haas machines llol
02:57 PM CaptHindsight: https://youtu.be/ZLDR0aJAYIA?t=150 the finish?
02:58 PM Tom_L: JesseG, didn't he get in trouble with the law a while back?
02:58 PM Tom_L: before stuart teamed up with him
02:59 PM XXCoder: .5kw thats 500w
02:59 PM Tom_L: tax fraud
03:00 PM CaptHindsight: https://en.wikipedia.org/wiki/Gene_Haas#Criminal_tax_evasion
03:00 PM Tom_L: guess it was the 'former chief financial officer'
03:01 PM JesseG: Tom_L, LOL my friend was telling me about that, but I forgot the details
03:01 PM Tom_L: https://www.nytimes.com/2006/06/20/business/20tax.html
03:01 PM Tom_L: a refresher
03:01 PM Tom_L: :)
03:02 PM CaptHindsight: XXCoder: that mill is mostly just Yaskawa parts
03:03 PM CaptHindsight: did they let him near the prison shop?
03:04 PM XXCoder: 14 year old news
03:05 PM Tom_L: somehow it stuck in my head though
03:05 PM CaptHindsight: still happened
03:05 PM Tom_L: i'm sure prison made him a new man
03:05 PM XXCoder: old days of actual justice
03:06 PM XXCoder: you know its old news when rich guy pays taxes and actually went to jail
03:08 PM CaptHindsight: https://www.kickstarter.com/projects/19659206/cnc-bt15-iso15-atc-spindles-cartridge-and-spindle
03:11 PM XXCoder: looks like it was successful project'
03:14 PM jymmmm: Ok, rounded up all the squirrels, power has been restored!!!
03:14 PM Tom_L: real power or squirrel power?
03:15 PM jymmmm: Tom_L Little of Column A, little of Column B =)
03:17 PM jymmmm: I replaced the oil drain plug with a ballcock valve, has held up well, when the gen cools down I'll do an oil change. Should be much simpler now
03:18 PM JesseG: I thought you wanted to do an oil change while the oil was still hot and stirred up to get out more of the suspended metal grit which will settle to the bottom and not run out when it's cold... :D
03:19 PM Tom_L: if you open it while it's running that will help push out all the oil...
03:19 PM JesseG: LOL... I guess it'll also pump all the oil out of the galleries also :P
03:19 PM jymmmm: Tom_L Ah, good idea! Silly me have been using the pull start to stir things up
03:20 PM Tom_L: naw, that's too much effort
03:20 PM jymmmm: Yeah, maybe I should use the electric start with the darin valve open???
03:20 PM jymmmm: drain*
03:21 PM Tom_L: good way to test the low oil sensor
03:21 PM JesseG: I *have* "drained" the antifreeze from an engine by revving it up a bit and popping off the radiator inlet hose. But I shut off the engine soon as the water stopped - which only took a couple seconds :P
03:22 PM JesseG: (I had the thermostat removed.)
03:22 PM JesseG: But I'd never drain the oil that way :P
03:23 PM jymmmm: Hmmm, I'm pondering getting this knife... https://www.amazon.com/Schrade-SCHF52-Frontier-Outdoor-Survival/dp/B011US7KWQ
03:23 PM JesseG: I did once start up a 1956 ford tractor with the oil pan off, but I had the oil pump intake connected to a tube in a jug of new oil :P (Had to make sure oil was getting everywhere. It was :P)
03:24 PM Tom_L: those didn't have the cup on the bottom of the rods for oil pickup? maybe that was older tech than 56
03:24 PM Tom_L: more like 40's
03:25 PM Tom_L: andypugh is familiar with those
03:25 PM JesseG: ya, this one had a regular gear pump run off the bottom of the distributor
03:26 PM andypugh: Scoops on the bottom of the con-rods were popular around WW1. I don’t know when they disappeared, but before WW11 in most cases. Basically anything with an oil pressure gauge won’t have them.
03:28 PM JesseG: haha yeah. This guy had called me out to fix his tractor. He's like "Yeah it's making a lot of bad noises and getting hot and losing power...." I says "Well did you check the oil?" he says "Oh yeah it's got plenty.."
03:28 PM JesseG: Last time I trust a customer :P
03:28 PM JesseG: so he offers to start it up so I can hear it... I says "Hey, you have no oil pressure.." he says "Oh, that hasn't worked in a couple years."
03:29 PM JesseG: We drop the pan and there's half a cup of oil in there.
03:29 PM JesseG: I says "hey, you said you'd checked the oil." he says "Well, it was a couple months ago. It doesn't use oil."
03:29 PM JT-Shop: my 56 Continental has an oil pump
03:30 PM JesseG: Anyway I put a new oil pump in for him and guess what - the oil pressure gauge suddenly started working.
03:30 PM Rab: JesseG, bet it uses oil now!
03:31 PM JesseG: Rab, yes, now it smokes and uses oil and fouls the plugs.
03:31 PM JesseG: He's thinking about rebuilding it. I'm not sure I want to do a rebuild for him if he is so likely to burn it up doing stuff like that :P
03:31 PM JesseG: like using it for 2 years with so little oil pressure that the gauge never moved it off zero :P
03:39 PM CaptHindsight: https://www.aliexpress.com/item/32758353154.html ~$700 but BT30
03:42 PM XXCoder: i wonder why bt30 is cheaper than smaller spindle bt20
03:44 PM andypugh: more supply?
03:44 PM XXCoder: possibly and more demend
03:46 PM CaptHindsight: ISO20 spindles with ATC are all higher priced so far
03:46 PM XXCoder: doh I meant iso20
03:47 PM Rab: "Some of you are already familiar with my BT30 spindle cartridges and my ER20 3.0KW electric square body spindle (or the china copies available on ebay) as well as my Sherline/Taig BT15 spindle conversions kits" ...anybody already familiar with these alleged products, and/or Dale Walsh?
03:51 PM andypugh: https://www.cnczone.com/forums/news-announcements/159067-bt15-belt-driven-atc-spindle-cartidge.html
03:53 PM Rab: andypugh, thanks!
03:54 PM andypugh: I am curious why he was banned from CNC zone
03:56 PM Rab: So am I, can't find the last posts from his profile without logging in.
03:57 PM Tom_L: was he trying to do commerce there? maybe that could be
03:57 PM CaptHindsight: "Given the deafening silence I'm receiving from Dave Walsh, I'm guessing he's got no interest in fulfilling all the pledges."
03:58 PM Tom_L: I have quite a large list of people who want them and I can't be forcing them to wait because you want 5 or more pieces and I can barely keep up with the production schedule as it is.
03:59 PM CaptHindsight: same guy as the kickstarter
03:59 PM Tom_L: may have bitten him
03:59 PM CaptHindsight: https://www.kickstarter.com/projects/19659206/cnc-bt15-iso15-atc-spindles-cartridge-and-spindle?ref=card
04:00 PM CaptHindsight: https://www.youtube.com/watch?v=xBg1Je-2lUo similar
04:01 PM Tom_L: UK is on lockdown now
04:02 PM CaptHindsight: https://www.cncdepot.net/
04:03 PM CaptHindsight: maybe I should make them
04:03 PM sync: andypugh: the guy is an idiot
04:03 PM CaptHindsight: where to stop
04:04 PM CaptHindsight: "dull minds think alike"
04:06 PM andypugh: The graphs don’t seem to show lockdown doing any good…
04:07 PM Tom_L: maybe it's a "he did it so i have to" mentality
04:07 PM andypugh: https://www.ft.com/coronavirus-latest
04:09 PM andypugh: I wonder if there will be more suicides than coronavirus deaths if we are all stuck at home alone for three weeks
04:09 PM Tom_L: hope we all have some projects to work on
04:10 PM roycroft: we'll be lucky if it's only three weeks
04:10 PM Tom_L: i built my mill while she was visiting her sister for a month
04:10 PM Rab: andypugh, I don't know about that, but I'm sure the increase will be non-negligible.
04:10 PM roycroft: i've sourced materials for several projects to keep me busy
04:10 PM roycroft: but i'm still working, and won't have any time off
04:10 PM andypugh: Am I allowed out of my house to go to my workshop?
04:11 PM roycroft: as long as "your workshop" is not "the pub"
04:11 PM Tom_L: i won't tell on you
04:11 PM roycroft: but yes, you should be able to go work in your shed
04:11 PM Rab: McMaster-Carr delivery is supposed to arrive on Wednesday, shelter-in-place order is supposed to come through tomorrow. :D
04:11 PM CaptHindsight: the tested numbers are pretty useless, unless you want to compare tests per capita
04:11 PM roycroft: mcmaster will still deliver
04:12 PM Rab: Mouser too, hopefully.
04:12 PM roycroft: all the delivery services will still operate
04:12 PM CaptHindsight: are they delivering in CA and NY?
04:12 PM roycroft: in oregon, we're on semi-lockdown
04:12 PM roycroft: yes
04:12 PM andypugh: Well, not all of them. I was about to arder some wine, but wine deliveries are off.
04:12 PM andypugh: Looks like a teetotal 3 weeks.
04:12 PM roycroft: the new rule, which came down today, is that all businesses whose workers can work from home must close their doors
04:12 PM CaptHindsight: i heard that they were not delivering to non essential businesses
04:13 PM roycroft: places like gyms must close
04:13 PM CaptHindsight: pcw_home: did you lose UPS and FEDEX service?
04:13 PM roycroft: capthindsight: that would make no sense
04:13 PM roycroft: using delivery services should be encouraged
04:13 PM roycroft: people will stay at home and order stuff online instead of driving to stores
04:14 PM CaptHindsight: well... sense you say :)
04:14 PM roycroft: president fuckhead has not ordered the lockdowns
04:14 PM andypugh: Can’t order food online.
04:14 PM roycroft: it's the state governors who are doing it
04:14 PM roycroft: so yes, one can expect some sensible decisions
04:14 PM andypugh: (No delivery slots available for weeks into the future)
04:14 PM roycroft: groceries can be ordered online here
04:14 PM roycroft: and delivered
04:15 PM roycroft: and restaurants are still open for take-away
04:15 PM roycroft: only curbside pickup though
04:15 PM JesseG: So is the general goal to slow the spread until decent testing be developed, or do people really think it can be contained and the genie can be put back in the bottle
04:15 PM pcw_home: CaptHindsight: not sure about UPS
04:15 PM roycroft: not just until decent testing can be developed
04:15 PM CaptHindsight: I'm going to try the curbside grocery pickup
04:15 PM roycroft: the real goal is to slow the rate of spread so that cases can be treated as they come up
04:15 PM roycroft: instead of hospital emergency rooms being totally swamped with a huge influx all at once
04:16 PM JesseG: roycroft, On a scale of 1 to 10, do you think containing it is actually possible?
04:16 PM roycroft: if the average hospital stay for covid-19 is 2 weeks, and you can spread the rate of infection out over 8 weeks, you can treat 4 times as many people
04:16 PM andypugh: And all those in hospital will die anyway
04:16 PM roycroft: no they won't
04:16 PM andypugh: SO what’s the point?
04:17 PM roycroft: but if everyone gets sick at the same time a much larger number will die
04:17 PM roycroft: jesseg: i don't think it's going to be contained for a long long time
04:17 PM roycroft: perhaps a year or more
04:17 PM andypugh: I exaggerate, but one stat I hard was that in the UK 32 pateints had been put on a ventilator and 31 of those had died.
04:17 PM gregcnc: h1n1 was a year
04:17 PM roycroft: it was more like 18 months
04:17 PM CaptHindsight: likely better overt he summer, then spike again when colder
04:18 PM roycroft: but if we slow down the rate of spreading it, more people can be saved
04:18 PM roycroft: we have no idea about that, capthindsight
04:18 PM roycroft: this is a brand new strain
04:18 PM JesseG: How big did h1n1 get before being contained? Because I don't recall everything grinding to a halt
04:18 PM roycroft: iirc about 15,000 people died world-wide
04:18 PM roycroft: and we're at that point already
04:18 PM CaptHindsight: we who?
04:18 PM roycroft: the world
04:18 PM gregcnc: somethign said because economy was in teh dumps they didn't do anything
04:19 PM roycroft: actually, obama took measures to stop it immediately
04:19 PM roycroft: please don't read the right wing propoganda that is 100% wrong about h1n1 :)
04:19 PM gregcnc: this was on CDC
04:19 PM roycroft: read the factual history
04:20 PM roycroft: obama declared a public health emergency days after the first case was reported in this country, and before the first death in this country
04:20 PM CaptHindsight: SARS-COV-2 doesn't survive as long on wet and warmer surfaces, which there are more of during summer
04:20 PM roycroft: and he got billions of dollars to combat it right away
04:20 PM roycroft: the right wing talking point that he did nothing for months refers to his declaring a national emergency
04:20 PM roycroft: which did take months
04:21 PM roycroft: but was not necessary until months into it
04:21 PM roycroft: he declared a national health emergency right away, and that got the money flowing to stop it
04:21 PM roycroft: the national emergency was to get money to help the economoy recover
04:21 PM JesseG: that's the beauty things. When you dump billions of dollars into it, a nasty virus goes away with no disruption. WHen you don't dump in billions of dollars, the whole world grinds to a halt.
04:21 PM roycroft: and then you get to dump trillions into it
04:22 PM JesseG: Could I just print up some overstuffed fake billion dollar bills and staple them on my house to keep away the virus?
04:23 PM roycroft: just stay safe
04:23 PM roycroft: all of you, please
04:23 PM Tom_L: JesseG, use TP instead
04:23 PM JesseG: Tom_L, oh yeah!! I was going to see if I could buy stuff at the store with TP instead of greenbacks
04:23 PM gregcnc: tp forst should protect everyone
04:24 PM roycroft: i can tell you all a secret now that i've gotten what i need
04:24 PM JesseG: The guy at Costco didn't want to touch my coscto card. He had me hold it up so he could scan it. He had no problem taking my money though.
04:24 PM roycroft: auto parts stores still have scott blue shop towels in quantity
04:24 PM JesseG: LOL
04:25 PM roycroft: sadly, i just had to buy some
04:25 PM JesseG: For TP?
04:25 PM gregcnc: https://www.nbcchicago.com/news/local/suburban-chicago-restaurant-offers-free-roll-of-toilet-paper-with-orders/2239505/
04:25 PM roycroft: and they're expensive at the auto parts stores - i paid $2.99/roll
04:25 PM roycroft: i usually order them by the case online for $2/roll, but my latest order got pushed back to may
04:25 PM roycroft: so i bought a half dozen rolls to tide me over until may
04:25 PM JesseG: Maybe I should make a machine that turns old newspapers, phone books, and junk mail into multi-colored TP
04:26 PM roycroft: i'm still not understanding the tp shortage
04:26 PM gregcnc: you still get a newspaper?
04:26 PM gregcnc: run on TP
04:26 PM JesseG: I don't still get the paper. But 20 years ago I did and I think I got a stack of them.
04:26 PM roycroft: if you have no food it doesn't matter if you have tp or not
04:26 PM roycroft: because if nothing's going in nothing will be coming out
04:26 PM roycroft: i can understand hoarding food a lot better than hoarding tp
04:27 PM JesseG: I just got 6 years worth of TP the other day. (A single 48 coscto pack LOL)
04:28 PM roycroft: anyway, for me, not only did i get supplies (and some new tools) to keep me busy, anticipating that i won't be able to go out and socialise for the indefinite future made me rethink the projects i have in my queue
04:28 PM cradek: anyone who's traveled in south asia knows there's billions of people in the world who just wash their butts after pooing and would really wonder what we're all on about
04:28 PM roycroft: i've been in a mode lately of just getting done what needs to be done right now
04:28 PM roycroft: but since i'll probably have a lot more time on my hands, i'm starting to do things more sustainably
04:28 PM roycroft: and more completely
04:30 PM CaptHindsight: https://howmuchtoiletpaper.com/
04:30 PM CaptHindsight: see how long your supply will last
04:30 PM roycroft: over the winter i bought a bunch of parts for my belt grinder, so i can make some more contact wheels
04:30 PM roycroft: and i've not gotten around to making any
04:30 PM SpeedEvil: UK's shut.
04:30 PM roycroft: i think i'll have the time to finish that project upnow
04:31 PM roycroft: yes, apparently "flatten the curve" is the new "the british people will just have to take it on the chin"
04:31 PM CaptHindsight: have to buy bangers and mash local :(
04:33 PM JesseG: CaptHindsight, I used to write the date inside the cardboard tube on a TP roll so when it ran out I could see how long it lasted.
04:33 PM JesseG: Also would tell me if a roommate switched it out on me :P
04:34 PM andypugh: I might actually go mad if I don’t leave the house or speak to anyone for 3 weeks.
04:34 PM gregcnc: do you also have a log of TP usage? how many years?
04:34 PM gregcnc: plan a trip to florida with all the spring breakers?
04:36 PM roycroft: folks here can still go outside to exercise
04:36 PM roycroft: and go to the market for food, of course
04:37 PM roycroft: and if i need to go into work i can - i work for an isp, which is considered a critical business
04:37 PM roycroft: and if i *do* need to into to work, it will be to an unstaffed data center or fiber hut
04:37 PM CaptHindsight: O gotta say those liberals and their hoaxes are great, they have whole world fooled :0
04:37 PM Deejay: gn8
04:37 PM roycroft: so my risk of exposure is quite minimal
04:38 PM roycroft: i'm at much higher risk when i buy groceries
04:38 PM andypugh: We can still go out to buy food. I am not sure if we can buy booze. And I doubt that tools and materials for projects count as essentials.
04:38 PM roycroft: yes, the home centers will still be open
04:39 PM andypugh: ?
04:39 PM CaptHindsight: some https://www.unionleader.com/news/health/coronavirus/hold-the-whiskey-nh-distillers-are-making-hand-sanitizer-now/article_7ab3b3c4-badc-5440-9177-4df5327118d2.html
04:39 PM roycroft: however, the number of customer permitted inside will be serverely restricted
04:39 PM andypugh: Why would they keep open home centres that you are not allowed to go to?
04:39 PM CaptHindsight: it happened, quick hide the whiskey
04:39 PM roycroft: they're considered essential
04:39 PM roycroft: landlords need to be to fix burt plumbing, etc.
04:39 PM roycroft: burst
04:40 PM CaptHindsight: good time to get the remodel project done
04:40 PM roycroft: police are not going to be stopping people for being outside
04:40 PM roycroft: that doesn't work
04:40 PM roycroft: it could never work
04:40 PM roycroft: and it puts the police at higher risk
04:40 PM andypugh: I _was_ planning to take some holiday and do the pointing on my mum’s house. But I doubt I will be able to get the supplies.
04:41 PM andypugh: And she is old, so high risk, so I probably shouldn’t/
04:41 PM roycroft: but if the cinema opens its doors, police would show up and shut it down
04:41 PM CaptHindsight: maybe drive ins will make a comeback
04:41 PM andypugh: Can I just get myself put in a mediacal coma ‘till its all over?
04:42 PM gregcnc: browsing the main stream media is sufficient
04:42 PM CaptHindsight: yeah should have a warning
04:47 PM Spida: sh... do you know the sound that occurs when you remove the load from an axial ball bearing you didn't know of?
04:47 PM gregcnc: oops
04:48 PM Spida: "here are your balls". separated way to much to feel comfortable.
05:03 PM JT-Shop: https://gnipsel.com/images/equipment/kubota/
05:28 PM pink_vampire: skunkworks: https://hackaday.com/2020/03/23/a-boring-tale-with-six-sides/ COOL!!
05:33 PM gregcnc: loo rolls? is that what they call them over there?
05:34 PM JesseG: haha cool
05:35 PM JesseG: I'd seen old fashioned bits for drilling square holes, but I guess no reason to not do it via cnc
06:00 PM _unreal_: sup
06:00 PM _unreal_: pink_vampire, are you on lock down?
06:00 PM pink_vampire: yeah
06:01 PM _unreal_: This whole thing is such BS its scary
06:01 PM _unreal_: now we are drownding in work
06:07 PM _unreal_: pink_vampire, tell me you at least have access to your machines?
06:11 PM skunkworks: pink_vampire: just found out - cooL!
06:13 PM pink_vampire: yeah, my machines are in my living room,
06:14 PM _unreal_: sweet
06:14 PM _unreal_: well time for this old boy to take a shower then I'm going to get back to trying to finish setting up the PSU for my new cnc
06:17 PM jthornton: wow Missouri almost doubled the number of cases today
06:17 PM pink_vampire: skunkworks: I need to try it one day with my machine
06:26 PM Tom_L: jthornton, it's ~89 up from 70 this AM
06:26 PM skunkworks: I need to grab the latest code from the machine...
06:26 PM Tom_L: here
06:26 PM pink_vampire: what do you think is better for cutting PCB climb vs conventional?
06:27 PM jthornton: Tom_L, I think a lot of the increase is due to more testing going on
06:27 PM jthornton: any cases near you?
06:28 PM Tom_L: 2 in town
06:29 PM Tom_L: they're about to put the county on shutdown
06:30 PM jthornton: nothing within 100 miles of me so far
06:30 PM Tom_L: one was brought in to the hospital from Colorado
06:30 PM Tom_L: not sure how the other one got it
06:31 PM Tom_L: being rural probably helps you
06:32 PM Tom_L: they are not testing unless they are showing signs here due to the lack of test kits
06:32 PM Tom_L: under 60 don't get tested right now
06:32 PM jthornton: yea just about ready to pull my head and tail under my shell and chill out
06:33 PM jthornton: just need a few more things to last a month without going out
06:33 PM Tom_L: i think we're good for ~60 days or so
06:34 PM Tom_L: kids won't be restricted to work due to defense contracts
06:35 PM jthornton: most things we have would last for quite some time like freezer meat
06:36 PM Tom_L: severe storms moving in late monday she tells me
06:37 PM jthornton: we get them tomorrow
06:39 PM pink_vampire: here we got some light snow today
06:41 PM _unreal_: jthornton, they dont call it the state of misery for nothing LOL
06:42 PM _unreal_: pink_vampire, PCB?
06:42 PM _unreal_: pink_vampire, what kind of cutting?
06:42 PM _unreal_: cutting the traces?
06:42 PM pink_vampire: yeah
06:42 PM _unreal_: one sec
06:42 PM pink_vampire: and also parting it
06:43 PM _unreal_: pink_vampire, https://www.amazon.com/gp/product/B00SMDOUPS/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
06:43 PM _unreal_: they do NOT ware down
06:43 PM _unreal_: but they also do not cut as fast as V cutter do
06:44 PM pink_vampire: I have the tools, but how it is better to cut, climb OR conventional?
06:44 PM _unreal_: oh
06:44 PM _unreal_: dosent really matter
06:44 PM _unreal_: your cut is so shallow its not enough to defelect the bit
06:44 PM jthornton: actually Missouri is the best place to live
06:45 PM _unreal_: pink_vampire, so does not really matter
06:45 PM _unreal_: I use those bits because I can use one bit to drill all of my holes, cut my traces, cut break patterns and cut out the board witht he same bit
06:45 PM _unreal_: its just not fast
06:45 PM _unreal_: easy to break if the feed is to high
06:46 PM pink_vampire: I need to make 2 pcbs.
06:46 PM _unreal_: well That would be the bit I suggest
06:46 PM _unreal_: other wise you can get the 1/32 V bits
06:46 PM _unreal_: BUT the v bits ware out
06:47 PM _unreal_: those one's I linked do not
06:47 PM pink_vampire: I'm using 4F endmills
06:47 PM _unreal_: 4f?
06:47 PM _unreal_: how big?
06:48 PM pink_vampire: 1/32", 1/16", 1/8"
06:48 PM _unreal_: you have a four flute 1/32?
06:49 PM pink_vampire: yes
06:50 PM _unreal_: hum
06:52 PM pink_vampire: I'm using climb fur cutting and tracing, but I was curious to see what people use here.
06:52 PM _unreal_: I have found no difference
06:52 PM _unreal_: climb or traditional
06:52 PM _unreal_: again, the cut is so shallow it doesnt defelect the bit
06:55 PM Elmo40: _unreal_, you making cuts??
06:59 PM _unreal_: ?
07:00 PM pink_vampire: I don't like the V bits
07:01 PM _unreal_: :)
07:18 PM _unreal_: OMG....
07:18 PM _unreal_: I just gave up waiting and setup an on line account to edit my geico stuff
07:18 PM _unreal_: freaking hell
07:18 PM Tom_L: they won
07:29 PM andypugh: Well, so, I am messing about with a Buster VM (Virtual machine in VMware Fusion on my mac)
07:30 PM andypugh: And the mouse pointer is really slow. So I found some advice on the internet to uninstall libinput.
07:30 PM andypugh: Now, that probably works on systems that have synaptics to fall back on....
07:30 PM _unreal_: and now your mouse is limp?
07:30 PM andypugh: but now I have a Buster that ignores all keyboard and mouse action.
07:31 PM _unreal_: can you telnet in
07:31 PM andypugh: Though the keyboard works in the recovery console
07:31 PM _unreal_: andypugh, try plugging a different keyboard it
07:31 PM _unreal_: if you have one. it may detect it?
07:31 PM andypugh: It’s a VM. so the Mac grabs it.
07:31 PM andypugh: Tried that.
07:31 PM _unreal_: Screwed
07:31 PM andypugh: ssh might be an option.
07:31 PM CaptHindsight: andypugh: saw the new RTAI deb package, memleak was worried about the howto instructions not being clear enough
07:32 PM CaptHindsight: thank you as well
07:32 PM andypugh: It would be nice to have an RTAI builbot slave
07:33 PM andypugh: I could, in theory, reinstall the driver, except that in recovery mode there is no network connection….
07:33 PM CaptHindsight: yeah
07:33 PM andypugh: I will just wipe and rebuild it. It’s only a VM.
07:34 PM CaptHindsight: not ideal but what about using some mamazon VM cloud thing as a buildbot?
07:34 PM _unreal_: hehe, I'm going to cut off your eyes, ears, tung, arms and legs. you can keep the pecker >:) now save your self
07:34 PM andypugh: I mean in the sense of a LinuxCNC buildbot on buildbot.linuxcnc.org
07:34 PM _unreal_: save your self VM
07:34 PM CaptHindsight: yes i know but that is Sebs hardware and bandwidth
07:34 PM roycroft: can't you ssh to the vm and fix the problem?
07:35 PM _unreal_: roycroft, I already said that
07:35 PM roycroft: then i'll withdraw my suggestion and second yours!
07:36 PM roycroft: in future, a snapshot of the vm right before doing the scary thing might be in order
07:36 PM andypugh: It uses bridged networking, I am not sure if I can see it on the network as a different “thing” than my Mac
07:36 PM roycroft: it uses bridged networking, but it has its own ip address
07:36 PM _unreal_: andypugh, can you local as in from the machine your ON tell net into it?
07:37 PM roycroft: usually in net 172 - it brings up the bridge to the mac
07:37 PM roycroft: so you should be able to ssh to it from the mac
07:37 PM roycroft: if you can figure out what ip address it's grabbed
07:37 PM _unreal_: omg two hours later and I'm 11 in queue
07:38 PM _unreal_: I'm on the fedelity live chat, going to talk to them about getting some stocks setup
07:38 PM _unreal_: and an account
07:39 PM _unreal_: oooooh number 10
07:39 PM _unreal_: one away from single digits
07:39 PM Rab: andypugh, is there a way to mount the image's filesystem? E.g. https://askubuntu.com/questions/19430/mount-a-virtualbox-drive-image-vdi
07:40 PM andypugh: I might be able to ut the .deb on a USB stick and mount that on the VM from the command line.
07:41 PM roycroft: in vmware fusion, you can go to the virtual machine settings -> network and get the mac address the vm is using
07:41 PM roycroft: and then, from the mac, arp -a will give you the match, with the ip address assigned to i
07:41 PM roycroft: t
07:41 PM _unreal_: wish I knew if this USB mach3 motion controller supports quadrature control. instead of just step/dir :(
07:43 PM _unreal_: wow the numbers are going down quick now
07:44 PM andypugh: roycroft: You might be on to something….
07:45 PM _unreal_: #5 in line
07:45 PM _unreal_: seems like the numbers are going down faster now
07:45 PM _unreal_: #4
07:46 PM roycroft: it's under advanced options in the vm settings ->network panel
07:47 PM roycroft: and if it doesn't show up when you issue the arp command, ifconfig -a on the mac will show you all the interfaces
07:47 PM roycroft: there will usually be two virtual machine interfaces
07:47 PM roycroft: vmnet1 and vmnet8
07:48 PM roycroft: your vm will probably be using vmnet8
07:48 PM _unreal_: Oh wow there is a us zip code 12345
07:48 PM andypugh: Thanks, that seems to have worked :-)
07:48 PM roycroft: cool
07:49 PM roycroft: i need not go any further then :)
07:49 PM andypugh: And that’s going to be a useful tactic in future.
07:49 PM roycroft: ok, then i'll finish, because i was almost done
07:49 PM andypugh: If nothing else for SCP file transfer
07:50 PM roycroft: if it doesn't show up, then if th eip address of vmnet8 on the mac is, for example, then ping
07:50 PM roycroft: that will populate the arp table with an entry for every device on the network
07:50 PM roycroft: and then the arp -a command will show you the entry for the mac address, if networking is functional on the vm
07:50 PM roycroft: if networking is not functional then you're screwed anyway :)
07:51 PM andypugh: Fixed !
07:52 PM andypugh: And, it even has a decent mouse speed now, as a bonus.
07:52 PM andypugh: So it even worked.
07:52 PM roycroft: brilliant!
07:53 PM roycroft: i should get back to sharpening, because it's a slow and tedious process, which is perfect for being homebound indefinitely
08:41 PM CaptHindsight: $2300 https://www.kickstarter.com/projects/535786699/flxarm-low-cost-precision-robotic-arm/description
08:43 PM Javabean: $2300... low cost... yeah,no
08:45 PM CaptHindsight: even worse one for $750 https://www.ebay.com/itm/4-Axis-SCARA-Robot-Mechanical-Arm-Hand-Manipulator-with-Stepper-Motor-Assembled-/252765883037
08:46 PM CaptHindsight: can't tell from the pics, die cast cheddar or a stiffer cheese?
08:48 PM Javabean: don't know... but i do know that as it is "pre assembled" i will have to take the damn thing apart, clean/fix/adapt it, then put it back together again before i can find out if they bothered to include the magic smoke in the electronics
08:48 PM Rab: From the pix, looks like G10 or maybe even PVC sheet.
08:49 PM CaptHindsight: yeah
08:56 PM CaptHindsight: high density milk solids
09:22 PM roycroft: so i just got an email from digi-key saying they intend to remain open for online business during the pandemic
09:22 PM roycroft: i've received nothing from mouser so far
09:23 PM roycroft: mcmaster say they will continue to ship, even to shelter in lace locations
09:23 PM roycroft: no will-call, of course
09:24 PM roycroft: not that i would drive down to reno for some fasteners
09:26 PM Rab: https://www.mouser.com/service-alerts/
09:26 PM roycroft: that's exactly what i would expect of mouser
09:27 PM roycroft: those suppliers are vital industries
09:27 PM roycroft: they supply the health care and public safety sectors
09:28 PM roycroft: so one would expect them to say "we're still open, we're bing safe, you can't show up at our door, but we'll ship stuff to you"
09:37 PM CaptHindsight: https://imagebin.ca/v/5Gfg9nbI5sMC which mill is more rigid?
09:54 PM _unreal_: That one
10:01 PM CaptHindsight: uh huh
11:37 PM pink_vampire: hi
11:44 PM JesseG: Howdy
