02:07 AM randy: morning
02:34 AM solarwind: Hi all, does anyone have a dependency list to compile linuxcnc on vanilla Ubuntu?
02:34 AM solarwind: That is, I don't want to have to keep adding dependencies every time the compile fails. I'd rather just `sudo apt install ... ... ... ...` all at once since all dependencies should be known
02:36 AM solarwind: I don't need any realtime components yet. I can compile a different kernel later.
02:36 AM solarwind: I'm just getting used to it for now, so getting it fully compiled would be a good start
02:42 AM CaptHindsight[m]: http://linuxcnc.org/docs/master/html/code/building-linuxcnc.html#Satisfying-Build-Dependencies
02:43 AM solarwind: CaptHindsight[m] thank you. I thought I checked those docs, not sure how I missed that

02:58 AM CaptHindsight[m]: https://imgur.com/gallery/WSQoaxw 8 hours of GOES orbital imagery showing Oregon Wildfires
04:06 AM Tom_L: morning
04:42 AM gloopz: so, a battery power supply, a stepper, some way of controlling the speed, what do i need?
04:46 AM gloopz: (barn door sky tracker)
04:59 AM JT-Cave: morning
04:59 AM XXCoder: heys
06:32 AM CloudEvil: glguy: Some means of either using a curved rod and stuff, or a speed controller that understands trig.
09:11 AM perry_j1987: morning
09:19 AM perry_j1987: trying that butter in coffee thing this morning
11:37 AM Roguish_shop: machining for $$$ today.
11:38 AM Tom_L: hope you find em
01:08 PM roycroft: great, letsencrypt.org is broken, and i'm in the middle of moving some websites
01:09 PM roycroft: i managed to revoke their certificates right before letsencrypt broke, but i can't issue new ones on the new host, so the sites are down until they fix their problem
01:27 PM CloudEvil: :/
02:31 PM jepler: roycroft: ow. https://letsencrypt.status.io/ "All issuance has been interrupted."
02:31 PM roycroft: yes, and it's been that way for about 3 hours now
02:31 PM roycroft: i have four websites that are non-functional because of it
02:32 PM jepler: oh and ocsp is disrupted too
02:32 PM roycroft: i put them in maintenance mode, revoked their certificates, and then moved them to the new server, at which point letsencrypt were down
02:32 PM * roycroft hopes they get it sorted soon
02:33 PM roycroft: if this goes on for much longer and the customers start complaining loudly i may have to purchase some commercial certs for them to get them back online
02:37 PM jepler: "our usual vendor for snake oil has had their lead times go up, do you want to wait or should I buy second-supplier snake oil for $60 more?"
02:37 PM jepler: everyone understands about lead times now :)
02:42 PM roycroft: lead times in the real world are measured in days, months, and years
02:42 PM roycroft: lead times in the minds of customers are measured in nanoseconds, microseconds, and milliseconds
02:43 PM roycroft: speaking of which
02:43 PM roycroft: i ordered some chisels in early march, that were scheduled to be delivered by the beginning of april
02:43 PM roycroft: i just got an email saying maybe september
02:56 PM roycroft: letsencrypt just upgraded to "degrated performance"
02:56 PM * roycroft tries to generate a cert
02:57 PM roycroft: it is not failing immediately
02:57 PM roycroft: this is an improvement
03:02 PM CloudEvil: roycroft: check it's not all 3s.
03:39 PM skunkworks: Dads starlink keeps getting better and better.. Latency is going down, Speed is going up and downtime is going down.
04:16 PM CloudEvil: :)
04:16 PM CloudEvil: And this is before LASER interlink
04:17 PM CloudEvil: I do wonder what they're paying for the basestations
05:17 PM perry_j1987: o/
05:17 PM perry_j1987: hows it going
05:51 PM roguish[m]: Tom_L: 4 of 6 parts done. 2 of 'em definitely the most difficult.
05:52 PM Tom_L: roguish[m], what are they for?
06:08 PM perry_j1987: got bit of shop reorganizing done so far today
06:09 PM perry_j1987: the center is opened up again heh
06:09 PM perry_j1987: can walk in here
06:19 PM Roguish_desk: Tom_L, parts for a packaging manufacturer's production line equipment. nothing complicated, just work... but it pays. they're on Cash in Advance basis because they hung me out way too long, too many times.
06:21 PM Tom_L: always interesting to see what ppl are working on
06:25 PM perry_j1987: think i maybe should get some beer for the shop fridge
07:36 PM roycroft: i'm still making jigs and fixtures, but i've actually started work on a product prototype, which i've added into the mix of things
07:36 PM roycroft: my goal is to start making products this summer, and there's a decent chance i'll reach that goal
08:31 PM CaptHindsight[m]: where does one find a vertical turning center? https://youtu.be/1OmrlXbbcU4?t=321
08:34 PM Tom_L: when one holds the camera 90deg
08:35 PM Tom_L: defies gravity too :)
08:43 PM CaptHindsight[m]: one would be handy when running short of floor space
08:46 PM Tom_L: not practical though
08:46 PM Tom_L: all the chips would collect around the chuck
08:50 PM CloudEvil: Hold it 270 degrees. Problem solved.
09:00 PM CaptHindsight[m]: Just mount the chuck at the highest point and add a chip pan to the tailstock. If the pan rotates with the material then chips would just get flung out of the way. :)
09:09 PM roycroft: using a lathe in space would be interesting
09:10 PM roycroft: chip management would have to be very well engineered
09:10 PM roycroft: as would coolant manatement
09:10 PM XXCoder: wow gravity defying person too
09:10 PM roycroft: management
09:10 PM roycroft: otoh, schlepping that 12" rotary table onto the milling machine bed would be a breeze
09:11 PM -!- #linuxcnc mode set to +v by ChanServ
09:12 PM JT-Mobile: yo
09:13 PM XXCoder: o/
09:14 PM JT-Mobile: in the mountains east of gatlinburg FD&H after dinner
09:14 PM roycroft: souhds like a fun place to be
09:14 PM * roycroft will be heading down to the southern oregon coast in 3 weeks
09:15 PM JT-Mobile: cool
09:15 PM roycroft: yes
09:15 PM roycroft: and the campground where i'm going has no internet and spotty cell phone coverage at best
09:15 PM roycroft: which is one of the reasons i like that campground so much
09:15 PM JT-Mobile: pretty tired after the long ride but glad to be here
09:16 PM * roycroft just milled up a bunch of beer wood
09:16 PM roycroft: the hardwood vendors around here label steamed european beechwood "BEER"
09:16 PM JT-Mobile: interesting
09:16 PM roycroft: they say it means "BEech EuRopean"
09:17 PM roycroft: but everyone calls it beer wood
09:17 PM roycroft: oddly, though, i was not drinking beer when i was milling it
09:17 PM Roguish: good evening all. Hey, is the Forum down??
09:18 PM JT-Mobile: some rituals should be adhered to
09:18 PM JT-Mobile: Roguish, been on the road all day dunno
09:18 PM Roguish: ok, just came up. really slow.
09:19 PM JT-Mobile: maybe sun spots
09:19 PM Roguish: thanks JT. how's the trip going?
09:19 PM JT-Mobile: good a bit of traffic in knoxville but ok otherwise
09:21 PM Roguish: enjou. be safe
09:22 PM JT-Mobile: will do
09:31 PM roycroft: the bootleg fire is now larger than lost angeles, and still growing at a rate of a football field every 30 seconds
09:31 PM XXCoder: if thats the case, then growth rate in least is being flattened
09:31 PM XXCoder: hopefully it will strunk to negative
09:32 PM roycroft: it's been a steady rate of growth for days
09:32 PM roycroft: good that it's not accelerating
09:32 PM roycroft: but it's not diminishing at all
09:36 PM XXCoder: considering growing edge normally means fairly exponental growth of area burnt per time, it being flat is due to more and more areas being contained
09:40 PM roycroft: it is being slowly contained
09:40 PM roycroft: but residences and businesses are still being destroyed
09:41 PM roycroft: i'm sure they're putting the greatest containment efforts where there are houses to protect, so that indicates that the fire is still controlling things
09:44 PM roycroft: southern oregon may have a dry lightning storm over the next few days
09:44 PM roycroft: that would certainly start dozens of new fires
09:44 PM XXCoder: no shit
09:51 PM roycroft: the governor of montana recently withdrew from a pact entered into by a dozen states pledging to abide by the paris accords
09:52 PM CaptHindsight: step right up folks, here's your chance to buy that room sized mill you've always wanted https://milwaukee.craigslist.org/tld/d/waukesha-surplus-to-the-ongoing/7353357991.html
09:52 PM roycroft: he said he believes that innovation, not government regulation, should address climate change
09:52 PM CaptHindsight: room sized, I mwant house sized
09:52 PM roycroft: two days later he asked the feds to declare his state a disaster area due to the climate-induced drought
09:53 PM XXCoder: https://images.craigslist.org/00k0k_2eGNPxXSKxVz_0lM0t2_1200x900.jpg interesting design
09:53 PM XXCoder: roycroft: gonna love self-owns
09:53 PM roycroft: i could make some pretty big parts with that thing
09:53 PM XXCoder: tons of old tool chests there too
09:54 PM Tom_L: nice okuma there
09:54 PM XXCoder: I dislike okuma
09:54 PM XXCoder: i used to run one, and I hated it
09:54 PM Tom_L: they're good machines
09:54 PM roycroft: i don't think i could haul that on my pickup
09:54 PM XXCoder: sure, but why do they error out on tool change from t1 to t1?
09:54 PM roycroft: even disassembled
09:55 PM XXCoder: i had to use unsafe gcode to prevent that error
09:55 PM XXCoder: but otherwise yes its good machine
09:55 PM XXCoder: shop i worked at, they retired it after it destroyed covers for third time
09:55 PM Tom_L: we never ran into that problem
09:56 PM XXCoder: i have no idea what right side box thing is. one i ran didnt have it
09:56 PM Tom_L: pallet changer probably
09:56 PM XXCoder: possibly because it looks exactly same otherwise
09:56 PM Tom_L: toumbstone
09:57 PM Tom_L: probably not toumbstone since it's a vmc
09:57 PM XXCoder: one i ran it only has window on tgat side. smallish one
09:57 PM Tom_L: we had a platform you had to step up to to get to the pallets
09:57 PM CaptHindsight: https://madison.craigslist.org/tls/d/verona-large-granite-surface-plate-36/7345827148.html $325
09:58 PM XXCoder: one of flaws i hated about that okuma is if you turn on chip cleaning coolant sprays it can overflow and make mess
09:58 PM Tom_L: changer was behind on a belt of like 99+ tools
09:58 PM CaptHindsight: ok now all the shops going out of business are selling
09:58 PM XXCoder: capt yeah look at ebay
09:58 PM XXCoder: so many dial indictors and shop stuff
09:58 PM XXCoder: small shops closing down
09:58 PM CaptHindsight: this plate is perfect for a high precision lathe or mill
09:58 PM CaptHindsight: already has the mounting holes
09:59 PM XXCoder: that surface is interesting. you could convert it to CMM due to all that bolts
09:59 PM Tom_L: looks like it may have been a cmm
09:59 PM XXCoder: or planned for that yeah. guys being vague "robot prokecy"
09:59 PM CaptHindsight: was specific built for a cnc robot project that never happened
09:59 PM Tom_L: mmm
09:59 PM Tom_L: just read that
09:59 PM CaptHindsight: anyway that is what a 24 x 36 usually costs
10:00 PM XXCoder: costs always been on hauling rather than item usually
10:00 PM XXCoder: very heavyu
10:00 PM CaptHindsight: XXCoder: https://grandrapids.craigslist.org/tls/d/grand-rapids-walter-grinders-helitronic/7341079363.html grinder like the other you looked at
10:00 PM XXCoder: shop i worked at, they have dead cell that they refuse to haul away because its value is still postive
10:01 PM CaptHindsight: really? $50k!
10:01 PM XXCoder: interesting
10:01 PM XXCoder: 6 axis grinder. great for making custom tools?
10:01 PM Tom_L: CaptHindsight, you wanted something with 5+ axis to play with
10:01 PM CaptHindsight: Tom_L: HAH! https://grandrapids.craigslist.org/tls/d/hopkins-daewoo-puma-v10-vertical-cnc/7350073804.html
10:01 PM Tom_L: heh
10:05 PM CaptHindsight: XXCoder: $200 extra for delivery from 100 miles away https://i.imgur.com/k6H0MPo.jpg
10:05 PM CaptHindsight: OSHA cert rigger $3500
10:06 PM XXCoder: not too bd, though not in market for one
10:07 PM CloudEvil: 'I don't do codes' ?
10:08 PM CaptHindsight: yeah, odd
10:09 PM CaptHindsight: maybe it's the error code https://images.craigslist.org/01313_4Hh2gtmZ0Qez_0CI0t2_1200x900.jpg
10:10 PM XXCoder: some buttons is handwritten
10:10 PM XXCoder: olviously very long service life
10:11 PM CaptHindsight: same code https://www.bidspotter.com/en-us/auction-catalogues/koster-industries/catalogue-id-bscko10323/lot-9e3604be-c928-4a43-8808-a8690107edd0
10:13 PM CaptHindsight: the machine has lost parameters
10:13 PM CaptHindsight: in Polish https://www.cnc.info.pl/fanuc-o-t-problem-z-uruchomieniem-t78167.html
10:15 PM CaptHindsight: finally i find one https://cleveland.craigslist.org/tls/d/newington-axis-cnc-machining-center/7321037249.html
