12:18 AM enleth: have you ever seen an estop-like emergency vent valve on a compressed air system?
12:26 AM enleth: not a pressure relief, that's obvious, but an additional system that opens a large diameter valve venting the piping out completely when a big red button gets pressed
12:27 AM enleth: fragalot: nothing of the sort right now, and if I do get any holding devices that are air powered, I'll be damn sure to install check valves on them so that they keep holding in case of any air system failures
12:27 AM fragalot: :-)
12:27 AM fragalot: the valve you're lookig for is a "safety pressure release valve" btw
12:28 AM enleth: I know some need a constant flow, like an air-powered vacuum table, but I'm probably going to avoid those anyway, a waste of power IMO
12:30 AM enleth: fragalot: google results are hopelessly contaminated with the automatic pressure relief valves
12:30 AM fragalot: so search on sites like SMC, Festo, metalworks, etc
12:31 AM enleth: in any case, I can just slap a large diameter gas-rated ball valve with a large comfortable handle on there and label it in large clear letters
12:31 AM fragalot: the main thing about them is that they have feedback contacts of the actuator position, are normally open, and more expensive.
12:32 AM fragalot: a 3-way ball valve would indeed work fine
12:33 AM enleth: the remote power control for the compressor sitting in the basement is going to be right there too, but shutting the compressor down in an emergency is really a secondary concern, even if it keeps running for a moment it's not going to be able to build up any sort of pressure with a large valve open to the atmosphere
12:34 AM fragalot: compressor side is not an issue with a 3-way valve like the smc VHS series
12:34 AM enleth: good point
12:40 AM enleth: I'm also lookin into automatic water removal for the tank, most likely a timer relay triggering an off-delay relay, so that every, say, six hours of actual compressor runtime the water drain valve opens for three seconds
12:40 AM fragalot: there is that, or there are float based mechanisms
12:40 AM enleth: I have no idea whatsoever as to what those two times should really be
12:40 AM enleth: but I imagine they're going to vary with ambient temperature and humidity
12:41 AM fragalot: dumb solenoid on a simple programmable timer would work
12:42 AM fragalot: or a standard auto drain valve that you'd normally put in-line with the air lines work work on the bottom of the compressor tank
12:42 AM fragalot: or at least, I can't think of a reason why it wouldn't
12:43 AM enleth: oh, and I'll have to tilt the tank slightly as some dolt installed the drain valve slightly higher than the very bottom
12:43 AM fragalot: don't worry about that last tiny bit too much
12:44 AM enleth: it's easier to mount the thing at an angle than it is to weld in a new valve and test the tank
12:44 AM fragalot: i'm off - good luck. :
12:44 AM fragalot: :)
12:44 AM enleth: thanks
02:10 AM Wolf__: hey syyl, thought you may appreciate this https://www.homemodelenginemachinist.com/threads/arduino-rotary-table-for-dummies.26744/ tho a bit late lol
03:01 AM Deejay: moin
03:12 AM Deejay: grumblfx
03:50 AM Loetmichel: *gnhihi* coworker is just cutting 150pcs spacer blocks 20mm*12mm*15mm out of 1/2" white POM sheet on the CNC router... Workshop looks like a blizzard went thru ;)
04:17 AM Net|: https://netpipe.ca/?page_id=2486
04:22 AM XXCoder1: Loetmichel: lol HUGE cnc mill at shop looked like it had blizzard inside after cutting so much nylon
04:28 AM Loetmichel: XXCoder1: you mean like this just in big? -> http://www.cyrom.org/palbum/main.php?g2_itemId=13888
04:28 AM Loetmichel: :-)
04:28 AM XXCoder1: yeah
04:28 AM XXCoder1: you could fit car inside machine
04:28 AM XXCoder1: though have to remove table lol
04:29 AM XXCoder1: table would serve as fairly narrow and extra long bed
05:40 AM jthornton: morning
05:40 AM Tom_L: morning
05:40 AM XXCoder1: morning
06:00 AM Deejay: hey there
06:00 AM * Deejay just had lunch
07:03 AM XXCoder1: making ring out of brass nut and dome nut https://www.youtube.com/watch?v=MgnlbDVuPdg
07:03 AM XXCoder1: end result looks interesting
09:31 AM CNC_Brian: Anyone had any experience of these $2000 Chinese Spindles?
09:52 AM jdh: I have a $400 chinese spindle
09:53 AM CNC_Brian: Im only want to use it for hobby user, but how many hours it will last I don't know.
09:53 AM CNC_Brian: I suppose its the bearings that will go and can be replaces
10:22 AM Loetmichel: sooo... returned home... now dinner (first thing i eat today), then a bit of sleep (5 hours or so), then a 700km drive, then drop off the goods at the customer and approval, then 700km back home. ;)
10:24 AM jthornton: you make sound like a long trip using kilometers lol it's only 435 miles
10:29 AM Loetmichel: jthornton: it is. about 7 hours on the road. two times. with an estimated 5 hour customer approval process in the middle
10:30 AM Loetmichel: and i am not really 20 any more ;)
10:39 AM JT-Shop2: last time I saw 20 was in 1973...
10:40 AM JT-Shop2: you just need to plug in a Kraftwerk cd and drive lol
10:40 AM Loetmichel: hihi... could help, yes
10:41 AM Loetmichel: i think i'll sleep a bit in the car on the way back when i get tired
10:42 AM Loetmichel: i am not used to doing 18 hours shifts any more ;)
11:00 AM kiboneu is now known as cnomad
11:10 AM jdh: I would not do so.
11:23 AM fragalot: Hi
12:03 PM fragalot: am I in here twice?
12:04 PM fragalot_: .. apparently a 2nd instance of irssi started ._.
12:04 PM gloops: yes
12:04 PM * fragalot shakes fist
12:05 PM gloops: hmm think ill get some more cutters from hong kong, less than 2 weeks seems to be the typical delivery time
12:05 PM gloops: but china - 6 weeks, strange
12:15 PM fragalot: gloops: have you ever looked at a map?
12:16 PM gloops: sometimes
12:16 PM fragalot: also, this damn welder is NOT selling at all
12:16 PM fragalot: 6 people have "bid" on it, but nobody actually wants to take it further than that
12:18 PM gloops: on ebay? you can pull it before the last 24 hours, but the last hour is when it all happens, as you know
12:18 PM fragalot: no, local site
12:18 PM fragalot: the bids mean nothing
12:19 PM CNC_Brian: Anyone recommend some open source or cheap CAM software to create NC code. Trying to use CAMWorks but way too complicated
12:19 PM fragalot: fusion360 is cheap & easy, but not open source
12:19 PM CNC_Brian: Needs to handle solidworks model
12:20 PM CNC_Brian: Yes I was using that on a student license but its expired
12:20 PM fragalot: the hobby license can be renewed every year for free
12:20 PM CNC_Brian: Really?
12:20 PM fragalot: and if you fall within the "I really should be paying for this" category,.. stop cheaping out
12:20 PM fragalot: yes - i've been using it for a few years now
12:21 PM CNC_Brian: No it really is just hobby use. Like to move into making money, but can't afford any decent equipment
12:22 PM fragalot: then it's free
12:22 PM CNC_Brian: Is there nothing open source worth looking at?
12:23 PM fragalot: probably, i've not really looked recently
12:33 PM gloops: there is freecad
12:35 PM gloops: blendercam
12:37 PM gloops: heekscnc
12:52 PM CNC_Brian: Thanks I will have a look Gloops
12:57 PM gloops: they dont compare to f360
01:55 PM renesis: fusion 360 is crazy good for CAM
01:56 PM renesis: i dont like the cad elements, like i hate how the view manipulation UI is setup, but for toolpath generation from models, super easy for how capable it is
02:11 PM CaptHindsight: https://imgur.com/gallery/2wKQEXL why bother with a bandsaw?
02:15 PM fragalot: I mean, he's cheating a bit by using multiple layers of paper folded like that
02:15 PM fragalot: but... damn.
02:46 PM Net|: https://netpipe.ca/wp-content/uploads/2019/01/image-15-1024x351.png
02:46 PM Net|: neat way to organise desktops
03:09 PM CaptHindsight: https://3dprint.com/233981/worlds-first-house-3d-printing-factory-opens-in-eindhoven-netherlands/
03:10 PM CaptHindsight: I want one made of chocolate and in the shape of a shoe
03:10 PM SpeedEvil: CaptHindsight: can't do that in the netherlands.
03:10 PM SpeedEvil: Printing shoes clogs it up.
03:10 PM CaptHindsight: <rimshot?
03:11 PM CaptHindsight: anything interesting going on?
03:12 PM tehnull: I'm eating really good pizza
03:12 PM CaptHindsight: https://3dprint.com/233821/when-should-3d-printing-be-used-in-sand-casting/
03:12 PM SpeedEvil: iI am eating tollerably good pizza.
03:13 PM CaptHindsight: nice chart comparing print cost and time for making sand molds
03:13 PM CaptHindsight: had mediocre pizza last night
03:14 PM CaptHindsight: no good options around here for pizza after 10pm, unless i drive an hour
03:15 PM gloops: i had decent fish and chips
03:16 PM tehnull: Keep a chunk of parmesan in the fridge, a cheese grater, and a few pickled peppers
03:16 PM tehnull: makes any mediocre pizza into a pretty bangin pie
03:16 PM CaptHindsight: they didn't compare resin coated sand cured by laser or DLP/LCD
03:18 PM CaptHindsight: tehnull: I have a fridge full of pizza components
03:18 PM CaptHindsight: some just can't be helped
03:18 PM tehnull: like home run inn
03:19 PM CaptHindsight: the 4 cheese is my favorite by Home Run
03:19 PM CaptHindsight: I tend to embellish it
03:20 PM CaptHindsight: good fish and chips are an hours drive as well
03:21 PM CaptHindsight: good Indian, middle eastern, Thai and Chinese ~20 minutes
03:21 PM CaptHindsight: there tons of bland, undercooked food and pizza around here
03:22 PM CaptHindsight: french fries are like mashed potato sticks
03:22 PM gloops: we'll have tonnes of fish and chips when we ban europeans from our waters
03:23 PM CaptHindsight: have they stolen all the fisheys?
03:23 PM gloops: yes you can hardly navigate the channel for fear of hitting a foreign trawler
03:24 PM gloops: theres nothing left, they even scrape the sea bed
03:26 PM CaptHindsight: I didn't know that the UK was starving
03:27 PM gloops: fish and chips is luxury dining here now
03:28 PM gloops: https://www.ebay.co.uk/itm/1-2-and-5-8-BSP-taps-and-dies/183635207632? quality pity there isnt a bigger set
03:28 PM CaptHindsight: https://www.bbc.com/news/uk-46912691 top story
03:28 PM CaptHindsight: crazy drivers
03:28 PM gloops: 97 year old with half a bottle of port in him
03:30 PM CaptHindsight: is there a faster way of printing sand molds than photopolymer coated sand cured by laser/DLP/LCD?
03:37 PM jthornton: down to 1 item on the bathroom remodel punch list :)
03:45 PM gloops: https://www.ebay.co.uk/itm/5pcs-6mm-Extra-Long-End-Mill-Double-2-Flute-Spiral-Bit-HSS-Aluminium-CNC-Cutter/222565242655? insane value
03:45 PM XXCoder1: jthornton: way to go
03:46 PM XXCoder1: gloops: not bad!
03:47 PM gloops: i wonder why single flute are more expensive than 2 or 4 though
03:47 PM JT-Shop: less common
03:47 PM XXCoder1: i wonder if symmetry got something to do with it.
03:47 PM XXCoder1: ah
03:48 PM gloops: they are less common on searches
03:48 PM gloops: 50 pence for 2 flute cutter £4 for single flute
03:50 PM gloops: those cheap ones i posted are HSS though, assumed they were carbide
03:51 PM XXCoder1: wondering if hss is fine for wood
03:51 PM XXCoder1: think so yeah
03:52 PM gloops: at those prices youll get a few good cuts, throw it away
03:52 PM gloops: not good when it gets hot though
03:53 PM * JT-Shop finds an 1840 one cent coin in his desk...
03:54 PM XXCoder1: did you lose it when it was new? ;)
03:54 PM JT-Shop: must have
03:57 PM gloops: 1840 - is that worth anything now? i mean over 1 cent
03:58 PM JT-Shop: it was worth $5 when Dad bought it who knows when
04:01 PM CaptHindsight: $35
04:01 PM XXCoder1: just dont try polish it before trying to sell it
04:01 PM XXCoder1: its one of biggest rookie coin seller mistake apparently
04:01 PM CaptHindsight: this one says even more https://www.usacoinbook.com/coins/229/large-cents/braided-hair-liberty-head/1840-P/small-date/
04:01 PM gloops: i know a lot of like old but not ancient coins had little value when i was a kid - same coins now are worth having, so many thrown away
04:03 PM JT-Shop: CaptHindsight: yea that's the one I have
04:04 PM CaptHindsight: hah MELT VALUE: $0.0651
04:05 PM JT-Shop: mine is pretty worn on the face side...
04:05 PM CaptHindsight: 180 years is a long time
04:06 PM XXCoder1: yeah. its still few dollars anyway
04:06 PM XXCoder1: unl;ess it gets so abused that you cant tell what coin it was, then its valyue is $.0651 lol
04:07 PM gloops: i found a really old coin in a field, didnt know what it was at the time, gave it to a local metal detector enthusiast to research it, never saw it again
04:07 PM CaptHindsight: did that once, never again
04:07 PM XXCoder1: didnt you get paperwork?
04:07 PM CaptHindsight: you find out who your friends are
04:08 PM gloops: no it was just a pure luck find, i didnt know anything about old coins or antiques or anything, i knew he was into that stuff so showed him and let him take it lol, that was that
04:09 PM CaptHindsight: I found a bunch of Buffalo Nickels on the sidewalk once
04:10 PM CaptHindsight: all in those cardboard and plastic wraps they display them in
04:10 PM Tom_L: what would a 43 penny be made of if not copper? nickel?
04:11 PM gloops: looks like they have some value CaptHindsight
04:11 PM gregcnc: they are all steel, except for the 3 or 4 documented copper ones
04:12 PM gregcnc: there was a real 43 copper penny just auctioned for 200+kUSD
04:14 PM gloops: they all used to look for edward VIII coins, he wasnt king for long so not so many with his head on them
04:14 PM Tom_L: was it just that one year?
04:16 PM CaptHindsight: Steel Composite Penny (1943)
04:17 PM CaptHindsight: https://www.usacoinbook.com/coins/small-cents/lincoln-wheat-cent/
04:17 PM CaptHindsight: 1943 D Bronze/Copper only 1 minted
04:19 PM CaptHindsight: they used to always say to look out for wooden nickels
04:43 PM Tom_L: CaptHindsight as a kid i always did cause they were worth a soda at the corner drug store
05:01 PM CaptHindsight: you had corner drug stores! :)
05:02 PM CaptHindsight: we had a ice cream parlor called "The Buffalo"
05:02 PM CaptHindsight: https://www.wbez.org/shows/wbez-blogs/lost-landmark-the-buffalo/841ff6ed-7230-4263-8bb0-f16fc29a2ef9
05:03 PM MacGalempsy: I need ice cream
05:04 PM CaptHindsight: yeah, don't mention food in here
05:04 PM CaptHindsight: everyone starts to get cravings
05:05 PM XXCoder1: didnt you know if you menion yummy food you must give reasonable amounts to everyone here?
05:05 PM XXCoder1: *the law of
05:05 PM CaptHindsight: did you have akid in school that brough enough gum for everyone just to stick it to the teacher?
05:06 PM CaptHindsight: "Did you bring enough for everyone?"
05:08 PM XXCoder1: we lived at school during weeks. different culture
05:09 PM XXCoder1: theres small amount of "day kids" that is bused in but..
05:09 PM CaptHindsight: looking back we mostly has assholes for teachers
05:09 PM CaptHindsight: a few decent ones in high school
05:11 PM CaptHindsight: a lesson Hillary didn't learn, don't come across like a 3rd grade petty tyrant telling you what books to stay away from, like physics, math and engineering
05:12 PM XXCoder1: i wish i was born say 10 to 15 years ago and not 40 years ago
05:12 PM XXCoder1: deaf school here is LOT better now than back then
05:12 PM CaptHindsight: I can imagine
05:13 PM XXCoder1: im the odd generation between "teach deaf minium" era and high quality schooling current
05:13 PM CaptHindsight: public school for the average child was better pre-70's
05:13 PM XXCoder1: mom went to school where teachers hit hands with ruler if she signed
05:14 PM XXCoder1: and punishment for repeats is requirement to sit on hands so cant use it
05:14 PM CaptHindsight: nice
05:14 PM XXCoder1: no, no it was not
05:14 PM CaptHindsight: <sarcasm>
05:14 PM XXCoder1: unless you mean cheanges to now then yeah, it is very
05:15 PM XXCoder1: i can't imange how mom went though from completely no tech to now
05:15 PM XXCoder1: she used to have giant tty machine lol
05:15 PM XXCoder1: sad grandfather threw it away :( its rare now
05:15 PM CaptHindsight: it's pretty well dumbed down now
05:16 PM CaptHindsight: I was shocked in the 90's when books on reading comprehension were 50% about inferences
05:16 PM CaptHindsight: talk about conditioning children
05:16 PM XXCoder1: not sure what inferences is
05:17 PM XXCoder1: ah evidence based and reasoning
05:17 PM XXCoder1: whats wrong with that?
05:18 PM CaptHindsight: they tell you what to infer
05:18 PM XXCoder1: if they tell you WHAT to think then its not critical thinking class
05:19 PM CaptHindsight: explains why current books and films are so predictable and rehashed
05:19 PM XXCoder1: also theres only so many stories to tell
05:19 PM XXCoder1: want more stories? expand into space :)
05:19 PM XXCoder1: then we have more stories to tell
05:19 PM CaptHindsight: plot twists
05:20 PM XXCoder1: im currently reading Timeline 191
05:20 PM CaptHindsight: it's about conditioning children to react to words and events the way you want them to
05:20 PM XXCoder1: amazing books by turtledove
05:20 PM XXCoder1: yeah thats opposite of what actual critical thinking is
05:21 PM CaptHindsight: here's an example...
05:21 PM XXCoder1: know what i prefer? questions that cant be answered, not answers that cannot be questioned. feyman
05:21 PM CaptHindsight: https://imgur.com/r/Danger5/r96Dt
05:21 PM XXCoder1: lol
05:22 PM XXCoder1: https://i.imgur.com/lg1wcSu.jpg what i thought also. lol
05:29 PM _unreal_: sup... ok so how do I go about installing linuxcnc to an installed ubuntu system?
05:30 PM jthornton: simple you build a real time kernel and install linuxcnc
05:30 PM jthornton: http://gnipsel.com/linuxcnc/uspace/
05:31 PM _unreal_: thats something I'm a little green on... also the computer I'm looking to install linuxcnc on is an asus tinkerboard running ubuntu
05:31 PM jthornton: did you look at the link?
05:32 PM jthornton: but no ubuntu instructions
05:32 PM jthornton: what is a tinkerboard?
05:32 PM Tom_L: an arm platform
05:32 PM rmu: tinkerboard is asus arm board in rpi formfactor
05:32 PM rmu: rockchip
05:33 PM jthornton: ah well that might be fun lol
05:33 PM rmu: also available with emmc
05:33 PM rmu: rt preempt seems to work
05:34 PM rmu: hm2_spi doesn't really work, watchdog bites within seconds
05:35 PM rmu: somebody in south east asia posted videos to youtube with a tinkerboard running linuxcnc/mesa system
05:36 PM jthornton: sounds challenging lol
05:36 PM Tom_L: sounds crazy
05:36 PM jthornton: that too lol
05:36 PM Tom_L: iirc i tried to steer him away from that board
05:38 PM MacGalempsy: dont let the watchdog bite ! WOOF
05:39 PM _unreal_: its about 2x the RPI in preformance
05:39 PM rmu: the board is quite performant
05:39 PM rmu: esp. with emmc
05:39 PM pcw_mesa: I think hm2_spi uses the kernel SPI driver which is liable to be bad for real time
05:40 PM _unreal_: I have had no issues with the board its fast like hell
05:40 PM rmu: yes it is using the kernel spi driver, and that uses the hardware spi engine
05:40 PM rmu: with dma
05:40 PM rmu: and that leads to waiting and preemption in the kernel, which is bad
05:40 PM _unreal_: parallel port works just fine. using a usb to pic 18f455... that was custom programmed for doing cnc
05:41 PM _unreal_: guy named CNCDUDEZ had this whole setup with lots of free software etc.... years back. now its all on archive.org
05:41 PM pcw_mesa: Yeah a polled non DMA driver would be better for SPI
05:41 PM _unreal_: but allthe code etc... is there
05:42 PM _unreal_: and its USB :)
05:42 PM MacGalempsy: anyone interested in some hocked goods?
05:42 PM _unreal_: hocked goods?
05:42 PM MacGalempsy: one is on a trailer and ready to be delivered :)
05:42 PM XXCoder1: someone sold it to mac
05:42 PM rmu: there is a generic bitbang driver in the kernel, in principle it should be possible to configure that onto arbitrary gpios via device tree, but i haven't figured out yet how
05:42 PM _unreal_: what is hocked
05:42 PM MacGalempsy: slang for sale
05:42 PM MacGalempsy: so I have a sinker EDM and a 20" drill press
05:43 PM XXCoder1: where is you mac :P so your offer is in context. also what stuff is lol
05:43 PM _unreal_: rmu, are youtalking about using the RPI I/O header as parallel port?
05:43 PM MacGalempsy: EDM is 30A 110v
05:43 PM XXCoder1: all I know you might be at exactly opposite side of globe from me lol
05:43 PM rmu: _unreal_: interfacing with a mesa 7i90 fpga card
05:43 PM MacGalempsy: and the drill press is 460v /3ph
05:43 PM _unreal_: OH
05:43 PM rmu: _unreal_: talking SPI
05:43 PM pcw_mesa: Yeah bitbanjg might be better than dealing with the general bustage of SPI hardware/drivers
05:44 PM pcw_mesa: Though hm2_rspi seems fine ((my test inst has been running 24/7 since July without issue)
05:46 PM XXCoder1: LOL first moments I think its small machine... then I see guy start it up
05:46 PM XXCoder1: https://www.youtube.com/watch?v=J2weoTGsi5c
05:52 PM _unreal_: so as I was saying before trying to figure out how to get started as far as building and installing linuxcnc for my asus tinkerboard
05:52 PM _unreal_: I'
05:53 PM _unreal_: I've looked at the page http://gnipsel.com/linuxcnc/uspace/ . but as I said I'm rather green when it comes to building custom kernals etc...
05:53 PM _unreal_: not that I cant do it but I just have not done it for like 10 years or so
05:53 PM XXCoder1: okay I assume macgalempsy lives at infinity distance away then
05:54 PM jthornton: he is in Texas I think
05:54 PM jthornton: well my tutorial should give you some hints...
05:55 PM XXCoder1: honesly distance is pretty small before savings gets eaten up
05:56 PM XXCoder1: and wa state has one of highest fuel cost lol
05:56 PM jthornton: what is regular gas up there?
05:56 PM jthornton: $1.89 here
05:56 PM XXCoder1: errrm $2.50 something?
05:57 PM XXCoder1: didnt really pay attention
05:57 PM XXCoder1: highest i ever paid was nearly $4 few years ago
05:58 PM XXCoder1: best and cheapest right now according to website is $2.61/gal
05:59 PM XXCoder1: I will never go to acro they suck
05:59 PM jthornton: I can remember filling up my `57 VW with $0.249 a gallon gas
05:59 PM rmu: _unreal_: what kind of machine do you have?
05:59 PM XXCoder1: costco maintans gas tanks pretty good so never any problem
05:59 PM _unreal_: I have the asus tinkerboard
05:59 PM _unreal_: trying to figure out how to install linuxcnc onto it. its running ubuntu
06:00 PM _unreal_: lubuntu
06:00 PM rmu: _unreal_: no i mean the cnc part
06:00 PM _unreal_: OH.
06:00 PM rmu: _unreal_: you can install linuxcnc and run it in simulation mode
06:00 PM _unreal_: I'm biulding it still slowly
06:00 PM _unreal_: work has been really busy
06:00 PM _unreal_: the machine will be a moving gantry mill
06:01 PM _unreal_: very very heavy duty
06:01 PM _unreal_: #@Q$%^#$%&^# phone again
06:01 PM rmu: _unreal_: generating signals for steppers from a rt-preempt-kernel will give a useful setup
06:01 PM rmu: will NOT give a useful setup
06:02 PM jthornton: steppers on a heavy duty gantry mill is an oxymoron
06:04 PM _unreal_: I have heavy duty steppers
06:04 PM _unreal_: :) I believe all 4 motors are like 8 lbs

06:07 PM rmu: _unreal_: you could probably make them work with something like powerstep01 drivers
06:07 PM rmu: either way, some amount of coding and tinkering ;) will be involved
06:08 PM _unreal_: looks like great GAS knots
06:10 PM _unreal_: you know nautical mile HA... haa.... ha....... GAS milage
06:11 PM _unreal_: so OMG.... every one tried to bypass ME and contact my daughter directly for her birthday

07:05 PM _unreal_: hum more like :( ]........
07:05 PM _unreal_: drop jaw
07:06 PM _unreal_: ok so as far as trying to get linux cnc setup on this tinkerboard..... what do I really need to do first?
07:15 PM _unreal_: ?
07:17 PM norias: .
07:18 PM _unreal_: ..
07:18 PM norias: oh.
07:19 PM _unreal_: oh my...
07:19 PM Tom_L: step 1: install linux
07:19 PM _unreal_: compleated
07:19 PM _unreal_: completed
07:19 PM Tom_L: step2: make sure it's rtai or preempt-rt
07:20 PM norias: step3: do stuff
07:20 PM norias: step4: profit
07:20 PM _unreal_: TinkerBoard-Lubuntu18.04LTS_ELAR-Systems-SD-v2.img
07:21 PM _unreal_: trai or preempt
07:21 PM _unreal_: ?
07:21 PM _unreal_: I dont know those terms directly
07:21 PM Tom_L: it's the realtime component you need to run linuxcnc
07:22 PM _unreal_: what would be my best way of finding out if I have preempt or rtai
07:23 PM Tom_L: you probably don't have either
07:23 PM Tom_L: unless you specifically installed linux with it

07:27 PM Tom_L: you'll have to translate those pages
07:27 PM norias: real time can be terrible for anything that doesn't need real time
07:27 PM _unreal_: its pre built
08:23 PM CaptHindsight: I heard they are working on getting the Rpi3 is QEMU
08:24 PM CaptHindsight: is/in
08:25 PM CaptHindsight: if they build it right then it will be easy to make kernels and Linux builds for them
08:25 PM CaptHindsight: not the shit from fedora or ubuntu
08:25 PM CaptHindsight: https://azeria-labs.com/emulate-raspberry-pi-with-qemu/
08:27 PM CaptHindsight: " there is currently no emulation of the BCM2835 USB controller, so there is no USB support and also, more critically, no networking support. Furthermore, the raspi3 model only works for 64-bit linux kernels, and the Raspbian kernel is 32-bit."
08:27 PM CaptHindsight: Date: 2018-10-12
08:44 PM CaptHindsight: oh yeah, that's right, it's Broadcom and not open source
08:51 PM CaptHindsight: https://en.wikipedia.org/wiki/Asus_Tinker_Board
08:51 PM CaptHindsight: GPU 600 MHz Mali-T760 MP4 GPU
08:52 PM CaptHindsight: https://developer.arm.com/products/graphics-and-multimedia/mali-gpus/mali-t760-gpu
08:53 PM CaptHindsight: https://wiki.debian.org/MaliMidgard
08:55 PM CaptHindsight: so unless you can live with the kernel they build the binary only drivers you are SOL for accelerated graphics
