12:17 AM drdoc: roycroft: commercial woodworking CNC will often handle a full 4x8 sheet
12:24 AM roycroft: yeah, that seems to be the standard size to me
12:24 AM roycroft: for what i want to do, 2'x4' is fine for now
01:21 AM Deejay: moin
04:05 AM Tom_L: morning
05:38 AM JT-Cave: morning

10:38 AM JT-Shop: yo
12:29 PM Tom_L: officially the weekend
01:12 PM roycroft: it has been for me since yesterday afternoon :)
01:15 PM Loetmichel: oh man, context completion. Brain is a curious thing. Just read `With that she jumped down the wall. A bone breaking, brain smashing twenty yards down...` in a book and thought "Nah, been there done that. just a bit uncomfortable. Then, a few sentences later... "Oh. yards. not feet."
02:40 PM JT-Shop: total for 2 scrap runs $497
03:03 PM CaptHindsight[m]: norias: looks good on the surface but...
03:03 PM CaptHindsight[m]: I really wonder what they are trying to really offer
03:04 PM -!- #linuxcnc mode set to +v by ChanServ
03:05 PM CaptHindsight[m]: space vehicles, drones, manufacturers are mostly staffed with young engineers with little experience
03:07 PM CaptHindsight[m]: "making precision components for SpaceX, Google, Lockheed Martin." are they going to make the parts for them since they can't make the parts internally?
03:08 PM CaptHindsight[m]: "Hadrian builds autonomous, software-defined precision component factories that help our customers make Rockets, Satellites, Jets & eVTOLs 2x faster and cheaper."
03:13 PM CaptHindsight[m]: who takes old car batteries these days?
03:17 PM Tom_L: i take mine back where i get new ones
03:18 PM Tom_L: cartel takes em
03:21 PM Tom_L: JT-Shop, how much is that an hour?
03:21 PM norias: CaptHindsight[m]: I wouldn't expect a lot of those places to make all of their components in house.
03:22 PM norias: CaptHindsight[m]: maybe the things that require a unique process, like some of the motor components.
03:26 PM Tom_L: looking at their jobs list, we've been doing all that crap here for years
03:26 PM JT-Shop: 50 cents an hour
03:27 PM Tom_L: nothing 'special' about them that i see
03:27 PM * Tom_L hi5's JT-Shop for keeping a job and staying off the streets!
03:27 PM JT-Shop: LOL
03:28 PM Tom_L: in fact, alot of companies come here looking for our engineers etc
03:29 PM Tom_L: my kid makes spacex parts... anybody can :)
03:30 PM Tom_L: i wouldn't wanna move to LA for a job anyway
03:31 PM Roguish: wow, it's a balmy 104 right now... still time to go higher
03:31 PM CaptHindsight[m]: the manufacturers seem to use whomever manipulates them best vs the other way around
03:31 PM Tom_L: ~96 here
03:32 PM CaptHindsight[m]: 72F here and partly cloudy with a light breeze
03:32 PM Tom_L: windy as heck here
03:33 PM CaptHindsight[m]: it felt like Wichita here the other day
03:33 PM XXCoder: 76f partially cloudy
03:34 PM Tom_L: it's been back and forth all spring/summer so far
03:34 PM CaptHindsight[m]: steady wind from the south. cleared the air up after a very humid and hot spell
03:34 PM CaptHindsight[m]: similar here, about a 8-9 day cycle of cooler and then warmer
03:35 PM CaptHindsight[m]: only high 60's here this weekend, and next is back to high 80's
03:35 PM Tom_L: surprised we haven't had more t-storms, hail etc here
03:35 PM CaptHindsight[m]: we started on those about a week ago
03:36 PM Tom_L: it's been soupy enough for it
03:36 PM CaptHindsight[m]: was a really dry spring early summer
03:36 PM CaptHindsight[m]: no mosquitoes until this week
03:37 PM CaptHindsight[m]: putting together a propane heated trap
03:37 PM CaptHindsight[m]: if you try to work with the doors open you get attacked
03:51 PM CaptHindsight[m]: https://electronics.stackexchange.com/questions/110574/how-to-choose-a-flyback-diode-for-a-relay
03:51 PM CaptHindsight[m]: https://electronics.stackexchange.com/questions/93452/correct-use-of-flyback-or-snubber-diode-across-motor-or-transistor
03:52 PM CaptHindsight[m]: https://electronics.stackexchange.com/questions/357392/selecting-flyback-diode-for-inductive-load
03:52 PM Roguish: thanks. reading now.
03:52 PM CaptHindsight[m]: one that switches fast enough, high enough current and voltage rating without wasting money
03:56 PM unterhausen: this 3d printed 4th axis looks fairly lame, but I guess he's just using it for lasing https://www.facebook.com/groups/unofficialshapeoko/posts/1097851643956127/
03:57 PM unterhausen: sorry private group

04:23 PM JT-Shop: when things are smooth usually 2 weeks for me
04:23 PM JT-Shop: are/were
04:23 PM Tom_L: that's real good
04:23 PM Roguish: Tom_L, I just read over the stuff Capt linked. couldn't find info on my contactor. it's a pretty good size Siemens. could actually measure the current, but checking my fav Amazon, can't get anything less that $4-$5..... found an assortment for $5. has lots, including 1n4001 thru 1n4007
04:23 PM Tom_L: Roguish, what's the coil voltage?
04:23 PM Tom_L: you want at least 2x that
04:24 PM Roguish: trying real hard not to damage the Mesa boards. oh, coil is 24vDC
04:24 PM Tom_L: https://www.ebay.com/p/1407936132?iid=313132410244
04:25 PM JT-Shop: the guy that complained the most still has not received his package I mailed on Apr 22nd but it's been in NZ for 8 days now
04:25 PM Tom_L: that should more than cover it
04:25 PM Tom_L: JT-Shop, maybe the post senses his attitude
04:25 PM JT-Shop: lol
04:26 PM JT-Shop: maybe the post know him...
04:28 PM Tom_L: Roguish, https://www.mouser.com/ProductDetail/Diodes-Incorporated/SB550-T?qs=sxN%252BoM2fis%252BarIksZvmXzg%3D%3D
04:28 PM Tom_L: should also be plenty
04:29 PM Tom_L: the coil current should be in the mA range
04:38 PM Tom_L: Roguish, they say basically the same thing: https://www.vpforums.org/index.php?showtopic=43291
04:39 PM Tom_L: 1n4007 or 1n5401
