05:55 PM * JT-Shop goes down to sit with the Piranha chickens
05:59 PM skunkworks: Tom_L: thanks1
05:59 PM skunkworks: !
06:00 PM Tom_L: may have missed a day
06:02 PM _unreal_: pcw_home, you live?
06:03 PM pcw_home: sort of...
06:04 PM pcw_home: just about out the door (as soon as my SO yells)
06:04 PM _unreal_: heh
06:05 PM _unreal_: enable on my stepper motor controllers any suggestions as to what connectrion I should tie them to on the 7i96
06:05 PM _unreal_: only running 4 steppers, xyzA when I have a rotory
06:05 PM pcw_home: what kind of signal do they need?
06:05 PM _unreal_: ttl
06:05 PM _unreal_: ttl + or -
06:06 PM _unreal_: https://www.ebay.com/p/21037462821?iid=254590201506&chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=254590201506&targetid=935083617547&device=c&mktype=&googleloc=9012012&poi=&campaignid=10877432047&mkgroupid=112821775411&rlsatarget=pla-935083617547&abcId=9300402&merchantid=108434799&gclid=Cj0KCQjw5eX7BRDQARIsAMhYLP_noUIBcyd6lq_HkvGms7-HOszirtILa-7OBzYrLYrFRE3HD1D6sVMaAhmiEALw_wcB
06:06 PM _unreal_: that is my motor controller
06:07 PM pcw_home: You could use a spare step/dir output, or an isolated output pulling to ground
06:08 PM _unreal_: I thought you were going to say that. ok then I'll look at DIR "TB2 dir4"
06:13 PM pcw_home: If you dont enable all stepgens, the unused step/dir outputs are available as GP outputs
06:14 PM pcw_home: bye yelling has commenced...
06:16 PM * JT-Cave thinks there is some conversation he is not seeing
06:16 PM XXCoder: JT-Cave: seeds in second eh heh
06:16 PM _unreal_: SHHHHHHHHHHHHH JT-Cave is listening
06:18 PM JT-Cave: dinner time here
06:45 PM XXCoder: yummy send me som
06:46 PM roycroft: stephen miller tested positive, xxcoder
06:46 PM XXCoder: looking up who
06:46 PM roycroft: if you don't know who he is you're lucky
06:46 PM XXCoder: ah trump's another asshole
06:46 PM Tom_L: not the guy with the band :)
06:47 PM roycroft: that would be steve miller
06:47 PM XXCoder: i wonder if trump is ok. he looked really bad
06:47 PM roycroft: we'll know later on this week
06:47 PM roycroft: i hope he is
06:48 PM XXCoder: i dont want pence to be president, not for a second
06:48 PM roycroft: but if things are going to go dowhill, that will likely happen on thursday/friday, or shortly thereafter
06:48 PM JavaBean: remember, the exact condition of the POTUS is classified... as its a matter of National Security
06:48 PM roycroft: but the one thing we know for sure about the novel corona virus is this:
06:49 PM roycroft: we don't know much for sure about it, and every time we figure out how it behaves it starts behaving differently
06:49 PM JavaBean: shhhh, certain sectors of the population would "lose their minds" if they heard about that
06:50 PM XXCoder: from what I read virus tend to sicken for while, get better for a bit then crash
06:50 PM XXCoder: latter sometimes leading to death
06:50 PM roycroft: that's the most typical behavior when things are not going to turn out well
06:50 PM XXCoder: im wondering if trump is at middle stage so he goes "im fine! go home now!"
06:50 PM roycroft: the person is feverish for a day or two, then appears to recover almost completely, only to go dowhill very quickly on day 6-8 after first showing symptoms
06:51 PM roycroft: but sometimes they have the fever for a couple days, then recover mostly or completely
06:52 PM XXCoder: im thinking former because he was breathing pretty hard
06:52 PM roycroft: sometimes after the fever they get better, then they get worse after a few days and stay fairly sick for a long time- sometimes months
06:52 PM roycroft: sometimes they get the fever and never get better
06:52 PM roycroft: it's impossible to predict what will happen until it happens
06:53 PM roycroft: dexamethasone indicates that he was in in pretty bad shape
06:54 PM XXCoder: yeah
06:54 PM roycroft: that's a very powerful steroid that has a lot of really bad side effects
06:54 PM XXCoder: its very much "if we have to" medicine
06:54 PM XXCoder: not "when person has something, we use this medicine" one
06:54 PM roycroft: and is usually only given to people who are having severe problems with their oxygen level
06:54 PM roycroft: and almost never given to anyone except in hospital
06:55 PM XXCoder: https://imgur.com/gallery/uTZxU5R
06:55 PM XXCoder: related
06:56 PM roycroft: remdesivir is an experimental drug and the president owns a lot of stock in the drug company who are developing it
06:56 PM roycroft: so publicity is the most likely reason he took that
06:56 PM XXCoder: possible though i wouldnt take dangerous medicine even if im in 400 million debt and need money
06:57 PM JavaBean: records show he has very little stock in that company
06:57 PM XXCoder: family member i think has more
06:58 PM roycroft: i do not have direct, personal knowledge of how much he owns
06:58 PM roycroft: so i'll withdraw my claim
06:58 PM roycroft: but i stil believe that he took it because he has an interest in it
06:58 PM roycroft: not because science believes it is a good idea
06:59 PM roycroft: at least he did not drink bleach
06:59 PM JavaBean: not saying you are wrong. but it has been described as one of the more promising treatments by media that is otherwise hostile to him
06:59 PM roycroft: i'm not saying i'm wrong either :)
06:59 PM roycroft: i'm saying that i don't personally know for certain
06:59 PM roycroft: so i'll just withdraw
06:59 PM roycroft: and it may end up being the miracle treatment
07:00 PM roycroft: but it's not proven (yet)
07:00 PM roycroft: i'll stand by my claim that he took it because he likes it
07:00 PM roycroft: not because it's effective
07:00 PM roycroft: even though it may be
07:00 PM roycroft: this president does not consider fact and truth and things like that when he makes decisions
07:01 PM roycroft: he only considers optics and what is good for him in the short term
07:01 PM roycroft: when he accidently does the right thing, but for the wrong reason, it's great that he did the right thing
07:02 PM roycroft: but not an indicator that he'll ever do the right thing again
07:02 PM roycroft: anyway, i should head back to the shop before we spend too much time off-topic again
07:03 PM JavaBean: that's the problem with having a "set topic", you can find yourself 3ly away from the topic in a conversation that WAS on-topic
07:03 PM buzzmarshall: the mans the biggest socialpath alive these days and 2nd only to his father and hasn't a clue about what the right thing is unless its strickly about himself
07:03 PM buzzmarshall: lol
07:04 PM XXCoder: buz if he deposted money in bank and earned only interest he'd have more money
07:04 PM XXCoder: ges 400million in debt
07:05 PM buzzmarshall: ya i was following his finacial shenanigans for awhile as i used to think he was smarter then he now appears
07:05 PM CaptHindsight: buzzmarshall: some people were raised so poorly that they can't see that or don't care
07:05 PM XXCoder: not always that
07:06 PM CaptHindsight: they are drawn to the strongman sounding type
07:06 PM XXCoder: sometimes its more basic than that. old human thing of following tribal lines
07:06 PM buzzmarshall: i think bloomberg was right when he trump was nothing more then the bully of the real estate industry but being president is way outside of his wheel house
07:06 PM CaptHindsight: XXCoder: I understand how the selfish are drawn to him
07:06 PM XXCoder: yeah
07:06 PM CaptHindsight: but the stupid that vote against their best interests?
07:07 PM CaptHindsight: they are just too broken to fix
07:07 PM buzzmarshall: everytime i think things are bad up here in canuckland i just look at what all my american buds have had to put up with and realize were not so bad off in the big picture
07:07 PM CaptHindsight: I see it like the macho we used to call it a few decades ago
07:08 PM CaptHindsight: empathy is seen as weakness, or showing of any feelings except for hate
07:08 PM CaptHindsight: I know people on disability that vote against it
07:08 PM CaptHindsight: they do take and cash the checks
07:08 PM XXCoder: yeah theres deaf for trump people
07:09 PM CaptHindsight: they don't see the connections
07:09 PM XXCoder: i saw one extreme trumper deaf person try to outright lie to other deaf people say republicans vote nov 3rd and democrats vote nov 4th
07:09 PM buzzmarshall: as a can that worked for a american company for almost ten years i was glad when he won and am kinda sad he's gonna loose this time around as with him in charge its finally making it easier for the can gov to start easing away from all the grap we've taken up here from the US and Can being its puppy dog
07:09 PM XXCoder: trying to cut votes. sounds very famililar
07:09 PM buzzmarshall: i just feel bad for the us people
07:10 PM CaptHindsight: buzzmarshall: sure you notice the small things, why some down here always bring up really awful countries as comparisons
07:10 PM CaptHindsight: they ignore northern Europe or Canada
07:11 PM buzzmarshall: true... normally i hate the politcal crap as one sides as bad as the other where ever you go but he's sure put a dent in the overall persecption others now have about the US
07:12 PM XXCoder: im not following "both sides is bad"
07:12 PM XXCoder: sure both sides have bad people
07:12 PM CaptHindsight: we really have the old class of white men that really think they are better than everyone else
07:12 PM XXCoder: i see percentage and republicans have far more bad people
07:12 PM buzzmarshall: normal people where ever you go seem to have always put up with the ruling classes stupidity
07:12 PM buzzmarshall: i just mean from a politcal stance which party...
07:13 PM buzzmarshall: here in Can is just as bad
07:13 PM CaptHindsight: they even entrench themselves in religion that reinforces this thought
07:13 PM CaptHindsight: so they fell that the invisible angry man in the sky is on their side
07:13 PM CaptHindsight: self righteous
07:13 PM buzzmarshall: for sure
07:14 PM CaptHindsight: we still debate womens rights, race, religion
07:14 PM CaptHindsight: it ridiculous, what year is this?
07:15 PM buzzmarshall: ya i don't get it either
07:15 PM JavaBean: very off-topic for channel.. but https://kvia.com/your-voice-your-vote/politics/2020/10/06/donald-trump-is-losing-by-16-in-a-new-cnn-poll-and-thats-not-the-worst-news/ and to me, the most "interesting"/scary part is the "and thats not the worst news" part
07:15 PM CaptHindsight: what I see is lots of taking advantage of the systems in place for their own benefit, not everyones
07:16 PM buzzmarshall: technically we move forward but morally were still stuck in that wayback days
07:16 PM buzzmarshall: we live in the me-generation now adays
07:17 PM CaptHindsight: if you are against national healthcare then why not also be against any medical research funded by it?
07:17 PM buzzmarshall: i thnk theres lots of good peeps around but no one seems interested in what they say so they just go quite leaving room for people wanting to take advantage
07:17 PM CaptHindsight: so if you get cancer and you were against it then you get the bible and holy water
07:18 PM CaptHindsight: I see that they want the benefits of everything but don't want to share the costs
07:19 PM CaptHindsight: i live in farm country
07:19 PM CaptHindsight: they don't see why they should have to pay taxes that cover everyone
07:19 PM JavaBean: CaptHindsight the costs to the taxpayer wouldn't be soo bad if, the companies weren't allowed to patent what they discover... even though they got a grant that covered 150% of the R&D costs
07:19 PM CaptHindsight: they just want to maybe pay taxes to cover their local village
07:20 PM CaptHindsight: JavaBean: it's been gamed
07:20 PM CaptHindsight: sure
07:20 PM CaptHindsight: privatize the profits, socialize the risks
07:21 PM CaptHindsight: all these double standards
07:21 PM JavaBean: all of this shit has been "gameified"... not just "healthcare"/"medical research"
07:21 PM CaptHindsight: my gods better than yours, my race is better than yours, men are better than women etc etc
07:21 PM JavaBean: but, did you check out that link i posted?
07:22 PM CaptHindsight: yes
07:23 PM JavaBean: only 1% polled were undecided... the debates barely started!!! but no, you decided to vote for "fox" to go into the chicken pen. never mind that "coyote" might have a point on many things you actually care about
07:27 PM CaptHindsight: seems that Marlin stays with the last feedrate manually entered vs falling back to what they say is the default jog speed
07:27 PM CaptHindsight: LIES LIES LIES!!!
07:28 PM CaptHindsight: can't wait to change over all this old printer stuff to LCNC
07:32 PM buzzmarshall: as a new face around here and still doing a lot of reading and researching LCNC and Machinekit what is the current status of LCNC with 3d printer stuff
07:46 PM buzzmarshall: currently i am working on arm based stuff for a machine ive built here so i looked at mk as most info seemed to say it was where to go with arm related
07:46 PM XXCoder: capt whats you doing with it?
07:46 PM XXCoder: make it a cnc something? or still printer but lcnc?
07:46 PM buzzmarshall: but in the last week or so i have since decided to go with LCNC and figure out a arm setup
07:46 PM buzzmarshall: ive a custom 4 color filament machine
07:46 PM buzzmarshall: that ive added a router to as i am doing guitar work
07:47 PM buzzmarshall: Mali is a ARM IP
07:48 PM buzzmarshall: thats why LE and OE and the rest don't have proper linux support at the hardware level
07:48 PM buzzmarshall: mostly all software rendering
07:49 PM CaptHindsight: we had Xenomai on the Allwinner about 7-8 years ago running at 40,000 latency
07:49 PM buzzmarshall: panfrost and lima are open source projects working on trying to create some open source
07:49 PM CaptHindsight: with software rendering
07:50 PM CaptHindsight: current issue with the Allwinners https://forum.linuxcnc.org/18-computer/39037-linuxcnc-orange-pi?start=40#178058
07:50 PM buzzmarshall: one of these days i will purchase a allwiner device when i have more time to play around
07:50 PM CaptHindsight: they post lots of source but not all
07:50 PM buzzmarshall: they look not bad just not what i need for my current project in cnc related stuff
07:50 PM CaptHindsight: much was also RE'd
07:53 PM buzzmarshall: currently some of us have re'd mali solutions for quite a while up to the malit820's in the s912 devices but nothing that would ever make its way outta private as none of us need the legal hassle
07:53 PM buzzmarshall: lol
07:53 PM buzzmarshall: i think the allwinner's mali is part of that same line
07:54 PM CaptHindsight: I forget if it's panfrost and lima on them
07:54 PM buzzmarshall: ive lost my interest in the media box scene and am more into the cnc thing
07:54 PM CaptHindsight: they work well enough now
07:54 PM buzzmarshall: ya there getting there
07:55 PM CaptHindsight: but with nvidia buying ARM this could be a dead end
07:55 PM buzzmarshall: and in most ways unless your looking for the real high end of their specs they work ok
07:55 PM buzzmarshall: ya thats gonna be interesting to see what twists come now
07:56 PM buzzmarshall: gpu market has always been a hot market
07:56 PM CaptHindsight: this is the GUI it should be able to display smoothly https://www.youtube.com/watch?v=Y4OaXS05ZMQ
07:56 PM buzzmarshall: im still trying to wrap my head around Arm letting itself be sold
07:56 PM CaptHindsight: the backplots is the only 3D
07:57 PM CaptHindsight: if there was Vulkan support then the backplots could be in full color and rendered with textures :)
07:58 PM buzzmarshall: cool....thanx for the link
07:58 PM buzzmarshall: i like that
07:58 PM CaptHindsight: https://www.youtube.com/watch?v=p-QRkQw8JpA
07:58 PM buzzmarshall: that is the direction i want to go
07:58 PM CaptHindsight: now Conversational
07:59 PM CaptHindsight: buzzmarshall: check out #hazzy
07:59 PM CaptHindsight: the QTPYVCP devs are in there
08:00 PM CaptHindsight: I need 4K and 8K video support but it's mostly just SVG layers
08:01 PM buzzmarshall: what i would like to do is create a decent cnc control system thats a couple of notches up from the atmel stuff but cheaper then getting into the serious coinage of the pro stuff
08:01 PM buzzmarshall: so i am trying read and learn so i can figure wher to jump in
08:02 PM buzzmarshall: ive copied alot of gits trying to glean all the differnt things i see and like
08:02 PM buzzmarshall: and am starting to understand more about what i need to do in building my own linux system
08:03 PM buzzmarshall: im old school from the bsd-slackware days
08:03 PM buzzmarshall: all these new fangled debian ubuntu things are nice but i don't like what ive seen in the arm part of them
08:04 PM buzzmarshall: ive got lcncn up and running on a couple of ubuntu boxes here running on pc platforms
08:04 PM buzzmarshall: and like what i see
08:04 PM buzzmarshall: and ive played around with some of the existing arm stuff for the beaglebones
08:05 PM CaptHindsight: https://github.com/sakaki-/gentoo-on-rpi-64bit
08:05 PM buzzmarshall: but id sooner go my own way and support only whats needed for cnc stuff and try and improve on the latency issues
08:07 PM buzzmarshall: ya i was looking at his stuff when i was checking out some rpi4 stuff for a LE fork some of us have privately
08:07 PM louipc: nice
08:07 PM CaptHindsight: actually a her
08:08 PM CaptHindsight: ready to go Gentoo you can start with
08:08 PM buzzmarshall: personally i had enough of broadcom crap in the satelite days and to be honest was kinda sad when i seen they decided to stay on broadcom when they designed the 4
08:08 PM CaptHindsight: I've never liked them
08:08 PM louipc: well. i did see a control with only 8 led array as the 'display' before and tape drive :D
08:09 PM CaptHindsight: worse than intel
08:09 PM buzzmarshall: from what little playing i did with the rpi4 i wasn't impressed with their gpio setup
08:09 PM louipc: so 'only whats needed' is subjective still
08:09 PM buzzmarshall: not for good timing
08:09 PM CaptHindsight: yeah they don't care about RT
08:09 PM buzzmarshall: to much work and the toolchains not what i want
08:09 PM buzzmarshall: im a low level guy
08:09 PM CaptHindsight: i used to write BIOS for PC's
08:10 PM buzzmarshall: all the high level crap for control stuff isnt in my wheelhouse
08:10 PM CaptHindsight: and u-boot
08:10 PM buzzmarshall: u-boot i like and have used for years
08:10 PM CaptHindsight: LinuxBIOS/coreboot
08:10 PM buzzmarshall: ive got a couple my own custom u-boot setups
08:10 PM buzzmarshall: based on the arm stuff
08:10 PM CaptHindsight: i like 1's and 0's
08:11 PM buzzmarshall: ya
08:11 PM louipc: those are the loneliest numbers
08:12 PM CaptHindsight: There are only 10 types of people in the world: Those who understand binary, and those who don’t
08:13 PM buzzmarshall: being a hardware guy
08:13 PM buzzmarshall: assembly was the easiest way for me to understand the electroncic to code transition
08:13 PM buzzmarshall: everythings basically just a switch
08:15 PM CaptHindsight: I started in analog
08:15 PM buzzmarshall: assembly being one step up from pure binary was what i cut my teeth on and just kinda stayed there as most of my coding/hardware interests were small devices
08:15 PM CaptHindsight: TV, RF, Microwave
08:15 PM buzzmarshall: cool
08:16 PM buzzmarshall: being a old musician my interest in electronics came from having to fix all my old tube amps in the way back days
08:16 PM buzzmarshall: i like analog
08:16 PM buzzmarshall: digital is great but i still like the old analog stuff
08:17 PM buzzmarshall: my nick came from all those old buzz'n marshall stacks we all carried around back then
08:17 PM buzzmarshall: lol
08:17 PM * JavaBean grabs a bowl of popcorn. watches a bunch of old people remember the old days, idly wonders who that is going arround stealing canes
08:17 PM buzzmarshall: lol
08:18 PM buzzmarshall: thats funny
08:18 PM buzzmarshall: regarding that gentoo on rasp thing
08:18 PM buzzmarshall: so do people have lcnc running on that?
08:19 PM buzzmarshall: and if so are they crosscompiling it or building on the device?
08:19 PM CaptHindsight: will here soon
08:19 PM CaptHindsight: likely on the Allwinner vs the Rpi
08:19 PM buzzmarshall: k
08:19 PM CaptHindsight: dislike debian/raspbian
08:20 PM CaptHindsight: been trying to get it it since last week
08:20 PM buzzmarshall: im ok with them on a normal intel machine but agree when it comes to the arm stuff
08:21 PM buzzmarshall: hm... i don't got anything allwinner right now but do have some rpi's kicking around here someplace under all the junk
08:21 PM buzzmarshall: maybe i should take alook at that github and see if i can build it for the rpi just to see how things work
08:21 PM CaptHindsight: I uncovered an H3 board either Orange or Banana Pi
08:22 PM CaptHindsight: still has the SD card in it, so I'll have to fire it up and see where we left off 6+ years ago
08:22 PM buzzmarshall: are you using that repo to try and build for the allwinner or you got some different sources your working off
08:22 PM JavaBean: isn't amazing what can end up in some of these piles?? found a 10mb/s ethernet card at the bottom of a box the other day
08:23 PM buzzmarshall: tell me about it... haha
08:23 PM CaptHindsight: buzzmarshall: actually I'm handing it all off the RTAI dev
08:23 PM CaptHindsight: I have hardware to build :)
08:24 PM buzzmarshall: two weeks ago i rented a 10yard dumpster bin to clean out years of crap to make room for my new project and came across crap ive not seen in years
08:24 PM CaptHindsight: I move every few years
08:24 PM buzzmarshall: thats one way to keep the pile smaller
08:24 PM CaptHindsight: evrything is in boxes and on pallets
08:25 PM CaptHindsight: so the pallets move from place to place
08:25 PM CaptHindsight: I'm trying to use all the old stuff up
08:25 PM CaptHindsight: saw a pandaboard
08:26 PM CaptHindsight: https://en.wikipedia.org/wiki/PandaBoard
08:26 PM CaptHindsight: things like that will end up on ebay
08:27 PM CaptHindsight: lots of 386/486 VIA ITX boards
08:28 PM buzzmarshall: if we keep this up JavaBeans gonna have to make some more popcorn
08:28 PM buzzmarshall: that panda thing looks neat
08:28 PM buzzmarshall: ive never had one of them
08:28 PM buzzmarshall: used a lot of TI stuff over the years just not their processors till i got a BBB
08:29 PM CaptHindsight: i try to use up older hardware on cheapskate customers
08:29 PM CaptHindsight: "can you make one for less?"
08:29 PM buzzmarshall: nothing wrong with that
08:29 PM buzzmarshall: i like recyling and seeing old stuff put back to use
08:30 PM buzzmarshall: if id had more rooom i would have not pitched all that stuff either
08:30 PM buzzmarshall: im not a big fan of this whole disposible thought pattern
08:31 PM buzzmarshall: if one can repurpose stuff why not
08:31 PM CaptHindsight: tomorrows problems belong to the kids
08:31 PM CaptHindsight: thanks
08:31 PM buzzmarshall: lol
08:31 PM * JavaBean shudders, wonders what the thoughts are on Fortran still being heavily used
08:32 PM CaptHindsight: if it works
08:32 PM JavaBean: considering the "panicked rush" to find people who can program in it... it may not be working so well these days
08:33 PM CaptHindsight: I can keep cars running for a million miles
08:33 PM buzzmarshall: ya one would think fortran programmers gotta be gettin a bit hard to find these days
08:34 PM CaptHindsight: Fortran, Cobol, Basic
08:34 PM buzzmarshall: but it does create a bit of a niche market for the ones that can
08:34 PM JavaBean: this human malware going around has caused many fortran based systems to get overwhelmed and crash
08:35 PM CaptHindsight: not really a Fortran problem, just old hardware that usually is good enough for expected loads
08:35 PM CaptHindsight: would have happened if it ran C
08:36 PM JavaBean: they can't upgrade the stuff away from the fortran systems if they can't get the formula's and maths out
08:36 PM CaptHindsight: who expects a pandemic? :)
08:36 PM CaptHindsight: just wise old people
08:37 PM CaptHindsight: Chicago's mass transit system still had a big blue processing payroll until 2010
08:37 PM JavaBean: and "the govenator"... that's right, arnie was the one who created what california thought was a great reserve of medical supplies... which had mostly gotten sold off "off the books"
08:38 PM CaptHindsight: thats just typical SNAFU and FUBAR
08:39 PM JavaBean: and corruption, but the point was... arnie saw shit coming and tried to prepare the state for it... and he wasn't "old" then
08:39 PM louipc: im less offended by fortran than javascript
08:40 PM CaptHindsight: I'm just anti *duino
08:40 PM CaptHindsight: buzzmarshall: do you take offense to the duinos hiding all the registers?
08:41 PM * JavaBean hides what's left of his RAMPS-based 3dprinter, which was upgrade to RAMPS from the original board
08:44 PM buzzmarshall: i started out on the older atmels prior to the duino stuff but did unfortunately play with the duino's when i started messing around with filament based 3d printers
08:44 PM buzzmarshall: wasnt a big fan of using someone else's front end
08:44 PM buzzmarshall: i prefer assembly and using atmels tools
08:44 PM buzzmarshall: atmels studio was kind nice
08:46 PM buzzmarshall: i am a self taught programmer and the whole C++ thing i understand it but am not really that sufficient as i don't do it enough
08:46 PM buzzmarshall: c i am better with because of my mac experiences
08:47 PM buzzmarshall: maybe if i would have started out in the atmels later in life i would appreciate the duiono stuff
08:48 PM buzzmarshall: being old tho makes one kinda stuck in the mud in some ways
08:48 PM buzzmarshall: haha
08:48 PM buzzmarshall: and by the time atmel started with their 32bit arm stuff i had moved off onto other boards
08:49 PM CaptHindsight: not really the fault of the *duinos but the reprap firmware rerally turned me off with all the upside down backwards dyslexic comments
08:49 PM buzzmarshall: ya i agree
08:49 PM CaptHindsight: marlin, Sprinter etc
08:50 PM CaptHindsight: just so awful
08:50 PM buzzmarshall: i quess it probably suited the guys creating at that time but i dont get it
08:50 PM buzzmarshall: i basically look at marlin and the rest of them as just hyjacked grpb project with the addition hot end ccontrol stuff added
08:51 PM CaptHindsight: https://www.klipper3d.org/
08:51 PM buzzmarshall: and to me when i look at all the things the poor atmels gotta handle it just cant do it properly
08:51 PM buzzmarshall: it cant keep up and then when people started added better displays trying to keep the market going it just got worse
08:52 PM CaptHindsight: KevinOConnor is an assembly guru, he wrote seabios for PC's to run older windows
08:52 PM buzzmarshall: ya i have his github and looked at his stuff
08:52 PM CaptHindsight: know him from the LinuxBIOS days
08:53 PM buzzmarshall: hes one of the few i think that actually no's whats going on
08:53 PM CaptHindsight: stop, think, ask, what is wrong with that?
08:53 PM CaptHindsight: nope just plow ahead and get stuck in a corner
08:54 PM buzzmarshall: problem with the 3d printer scene is mostly all of its being sucked up by the cheap makers who don't want to invest in anything so they just copy whatever they can pilfer from the open source guys
08:54 PM buzzmarshall: its all about cheap
08:54 PM buzzmarshall: and free
08:55 PM buzzmarshall: ive looked at pretty much all the projects and boards in the last two years while planning on my own system
08:55 PM roycroft: so, it was oil change time for my prius
08:55 PM roycroft: toyota dealership: $900
08:55 PM buzzmarshall: i just took the time to build the machine first while laying out boards
08:55 PM roycroft: my mechanic: $175 (and he does not use synthetic oil)
08:55 PM buzzmarshall: yeozer
08:55 PM roycroft: jug of synth oil + oil filter from local car parts store: $43
08:55 PM roycroft: add 20 minutes of my time
08:55 PM roycroft: i hate working on cars
08:55 PM roycroft: i opted to do it myself
08:57 PM roycroft: i'm willing to do things i hate to do when it's the logical path
08:58 PM roycroft: i hate working on cars enough that if my mechanic would use the proper oil i'd be willing to pay him the $175
08:58 PM roycroft: jiffy lube and that ilk are not even options
08:59 PM roycroft: because i'm not ready to get rid of this car
09:00 PM CaptHindsight: can't trust jiffy to not break something
09:00 PM Tom_L: it's how they generate revenue
09:04 PM roycroft: i don't get why he hates synthetic oil so much
09:04 PM roycroft: yes, he's old
09:04 PM roycroft: but i'm older
09:04 PM roycroft: and i can change with the times
09:05 PM roycroft: synthetic oil is superior in almost every way
09:05 PM roycroft: it may be because i can run 15,000 miles on synthetic oil without a change, while extracted oil requires a change every 3,000 miles
09:05 PM roycroft: so 1/5 the oil change revenue for him
09:05 PM Tom_L: probably a similar transition took place when whale oil was replaced with crude
09:06 PM roycroft: yeah, but we did this like 40 years ago
09:06 PM roycroft: synthetic oil is not new
09:06 PM roycroft: enough time has passed for even the most stubborn luddite to have accepted it
09:07 PM roycroft: and btw, it has been a full 15,000 miles since i changed the oil
09:07 PM roycroft: and it was still mostly clear
09:07 PM roycroft: and i've not been topping it off - my engine is tight and i'e added maybe a half liter in 15,000 miles
09:08 PM roycroft: extracted oil would have been mud by now
09:08 PM roycroft: actually it would have been mud 10,000 miles ago, at least
09:15 PM jdh: after 5k miles?
09:16 PM roycroft: yup
09:16 PM roycroft: the old stuff did not last long
09:18 PM CaptHindsight: the problem with popular resin printer software is it's all closed source
09:18 PM CaptHindsight: and most people don't care...... yet
09:21 PM roycroft: i don't care about closed source vs. open source per se
09:21 PM roycroft: as long as it works
09:22 PM CaptHindsight: https://home.cbd-3d.com/hardware/controller-board/chitu-l-m18-9-4k-monochrome/
09:22 PM roycroft: but as the closed source outfits get more and more intrusive i am starting to care more
09:22 PM CaptHindsight: almost works
09:22 PM CaptHindsight: and then your files are all in some proprietary format
09:23 PM roycroft: i *do* care a lot about file format standards
09:23 PM CaptHindsight: STM32 at least
09:23 PM roycroft: that's what really matters
09:23 PM buzzmarshall: ive not played with any resin based printers yet so i am not sure what software they are using
09:24 PM CaptHindsight: https://home.cbd-3d.com/software/chitubox/
09:24 PM CaptHindsight: or nanodlp
09:24 PM buzzmarshall: ive got a few STM32 dev boards here as well and actually don't mind them
09:24 PM CaptHindsight: https://www.nanodlp.com/
09:24 PM CaptHindsight: awful
09:25 PM CaptHindsight: you can tell they never wrote CNC apps before
09:25 PM buzzmarshall: and if it runs on stm32 i can probably re most things
09:25 PM CaptHindsight: don't even use preempt_rt on the Rpi's
09:25 PM buzzmarshall: ive got most of the tools required to dump their firmware and code and my own core emulators for idapro
09:26 PM CaptHindsight: it's so dumb, you need different hardware for different displays
09:26 PM buzzmarshall: so re is easier on there stuff... i used to re alot of st stuff in sat tuners
09:27 PM CaptHindsight: I'm just using LCNC
09:27 PM buzzmarshall: everyones gotta have their own solution i quess
09:27 PM CaptHindsight: and writing GUI's
09:28 PM CaptHindsight: none support multiple displays or 8K, except LCNC of course
09:28 PM CaptHindsight: on a PC
09:33 PM buzzmarshall: thats cool
09:33 PM buzzmarshall: ive decided to go with lcnc as well
09:33 PM buzzmarshall: i will work as well on a pc but also crosscompile for arm
09:34 PM buzzmarshall: right now i am just trying to learn linuxcnc's exact requirements for linux so i can adapt for arm
09:35 PM buzzmarshall: at a basic level and then progress from that point to the qui stuff as well
09:35 PM buzzmarshall: anyways i gotta go fix up a couple of failed compiles before crashing for the nite
09:36 PM buzzmarshall: and its been a slice... it would be nice to talk again
09:37 PM buzzmarshall: gotta be up at 6am and still got some fixup here so i'll catch you guys l8tr... nite
10:24 PM CaptHindsight: heh, found an Orange Pi from 7 years ago, it already has LCNC on it
10:24 PM roycroft: is that something like a key lime pie?
10:25 PM CaptHindsight: https://orangecnc.gitlab.io/
11:00 PM _unreal_: https://www.youtube.com/watch?v=7J33khH0KjY cool as hel
